This file is offered as-is, without warranty of any kind. Basic Installation ================== Briefly, the shell commands `./configure; make; make install' should configure, build, and install this package. The following more-detailed instructions are generic; see the `README' file for instructions specific to this package. Some packages provide this `INSTALL' file but do not implement all of the features documented below. The lack of an optional feature in a given package is not necessarily a bug. More recommendations for GNU packages can be found in *note Makefile Conventions: (standards)Makefile Conventions. The `configure' shell script attempts to guess correct values for various system-dependent variables used during compilation. It uses those values to create a `Makefile' in each directory of the package. It may also create one or more `.h' files containing system-dependent definitions. Finally, it creates a shell script `config.status' that you can run in the future to recreate the current configuration, and a file `config.log' containing compiler output (useful mainly for debugging `configure'). It can also use an optional file (typically called `config.cache' and enabled with `--cache-file=config.cache' or simply `-C') that saves the results of its tests to speed up reconfiguring. Caching is disabled by default to prevent problems with accidental use of stale cache files. If you need to do unusual things to compile the package, please try to figure out how `configure' could check whether to do them, and mail diffs or instructions to the address given in the `README' so they can be considered for the next release. If you are using the cache, and at some point `config.cache' contains results you don't want to keep, you may remove or edit it. The file `configure.ac' (or `configure.in') is used to create `configure' by a program called `autoconf'. You need `configure.ac' if you want to change it or regenerate `configure' using a newer version of `autoconf'. The simplest way to compile this package is: 1. `cd' to the directory containing the package's source code and type `./configure' to configure the package for your system. Running `configure' might take a while. While running, it prints some messages telling which features it is checking for. 2. Type `make' to compile the package. 3. Optionally, type `make check' to run any self-tests that come with the package, generally using the just-built uninstalled binaries. 4. Type `make install' to install the programs and any data files and documentation. When installing into a prefix owned by root, it is recommended that the package be configured and built as a regular user, and only the `make install' phase executed with root privileges. 5. Optionally, type `make installcheck' to repeat any self-tests, but this time using the binaries in their final installed location. This target does not install anything. Running this target as a regular user, particularly if the prior `make install' required root privileges, verifies that the installation completed correctly. 6. You can remove the program binaries and object files from the source code directory by typing `make clean'. To also remove the files that `configure' created (so you can compile the package for a different kind of computer), type `make distclean'. There is also a `make maintainer-clean' target, but that is intended mainly for the package's developers. If you use it, you may have to get all sorts of other programs in order to regenerate files that came with the distribution. 7. Often, you can also type `make uninstall' to remove the installed files again. In practice, not all packages have tested that uninstallation works correctly, even though it is required by the GNU Coding Standards. 8. Some packages, particularly those that use Automake, provide `make distcheck', which can by used by developers to test that all other targets like `make install' and `make uninstall' work correctly. This target is generally not run by end users. Compilers and Options ===================== Some systems require unusual options for compilation or linking that the `configure' script does not know about. Run `./configure --help' for details on some of the pertinent environment variables. You can give `configure' initial values for configuration parameters by setting variables in the command line or in the environment. Here is an example: ./configure CC=c99 CFLAGS=-g LIBS=-lposix *Note Defining Variables::, for more details. Compiling For Multiple Architectures ==================================== You can compile the package for more than one kind of computer at the same time, by placing the object files for each architecture in their own directory. To do this, you can use GNU `make'. `cd' to the directory where you want the object files and executables to go and run the `configure' script. `configure' automatically checks for the source code in the directory that `configure' is in and in `..'. This is known as a "VPATH" build. With a non-GNU `make', it is safer to compile the package for one architecture at a time in the source code directory. After you have installed the package for one architecture, use `make distclean' before reconfiguring for another architecture. On MacOS X 10.5 and later systems, you can create libraries and executables that work on multiple system types--known as "fat" or "universal" binaries--by specifying multiple `-arch' options to the compiler but only a single `-arch' option to the preprocessor. Like this: ./configure CC="gcc -arch i386 -arch x86_64 -arch ppc -arch ppc64" \ CXX="g++ -arch i386 -arch x86_64 -arch ppc -arch ppc64" \ CPP="gcc -E" CXXCPP="g++ -E" This is not guaranteed to produce working output in all cases, you may have to build one architecture at a time and combine the results using the `lipo' tool if you have problems. Installation Names ================== By default, `make install' installs the package's commands under `/usr/local/bin', include files under `/usr/local/include', etc. You can specify an installation prefix other than `/usr/local' by giving `configure' the option `--prefix=PREFIX', where PREFIX must be an absolute file name. You can specify separate installation prefixes for architecture-specific files and architecture-independent files. If you pass the option `--exec-prefix=PREFIX' to `configure', the package uses PREFIX as the prefix for installing programs and libraries. Documentation and other data files still use the regular prefix. In addition, if you use an unusual directory layout you can give options like `--bindir=DIR' to specify different values for particular kinds of files. Run `configure --help' for a list of the directories you can set and what kinds of files go in them. In general, the default for these options is expressed in terms of `${prefix}', so that specifying just `--prefix' will affect all of the other directory specifications that were not explicitly provided. The most portable way to affect installation locations is to pass the correct locations to `configure'; however, many packages provide one or both of the following shortcuts of passing variable assignments to the `make install' command line to change installation locations without having to reconfigure or recompile. The first method involves providing an override variable for each affected directory. For example, `make install prefix=/alternate/directory' will choose an alternate location for all directory configuration variables that were expressed in terms of `${prefix}'. Any directories that were specified during `configure', but not in terms of `${prefix}', must each be overridden at install time for the entire installation to be relocated. The approach of makefile variable overrides for each directory variable is required by the GNU Coding Standards, and ideally causes no recompilation. However, some platforms have known limitations with the semantics of shared libraries that end up requiring recompilation when using this method, particularly noticeable in packages that use GNU Libtool. The second method involves providing the `DESTDIR' variable. For example, `make install DESTDIR=/alternate/directory' will prepend `/alternate/directory' before all installation names. The approach of `DESTDIR' overrides is not required by the GNU Coding Standards, and does not work on platforms that have drive letters. On the other hand, it does better at avoiding recompilation issues, and works well even when some directory options were not specified in terms of `${prefix}' at `configure' time. Optional Features ================= If the package supports it, you can cause programs to be installed with an extra prefix or suffix on their names by giving `configure' the option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'. Some packages pay attention to `--enable-FEATURE' options to `configure', where FEATURE indicates an optional part of the package. They may also pay attention to `--with-PACKAGE' options, where PACKAGE is something like `gnu-as' or `x' (for the X Window System). The `README' should mention any `--enable-' and `--with-' options that the package recognizes. For packages that use the X Window System, `configure' can usually find the X include and library files automatically, but if it doesn't, you can use the `configure' options `--x-includes=DIR' and `--x-libraries=DIR' to specify their locations. Some packages offer the ability to configure how verbose the execution of `make' will be. For these packages, running `./configure --enable-silent-rules' sets the default to minimal output, which can be overridden with `make V=1'; while running `./configure --disable-silent-rules' sets the default to verbose, which can be overridden with `make V=0'. Particular systems ================== On HP-UX, the default C compiler is not ANSI C compatible. If GNU CC is not installed, it is recommended to use the following options in order to use an ANSI C compiler: ./configure CC="cc -Ae -D_XOPEN_SOURCE=500" and if that doesn't work, install pre-built binaries of GCC for HP-UX. HP-UX `make' updates targets which have the same time stamps as their prerequisites, which makes it generally unusable when shipped generated files such as `configure' are involved. Use GNU `make' instead. On OSF/1 a.k.a. Tru64, some versions of the default C compiler cannot parse its `' header file. The option `-nodtk' can be used as a workaround. If GNU CC is not installed, it is therefore recommended to try ./configure CC="cc" and if that doesn't work, try ./configure CC="cc -nodtk" On Solaris, don't put `/usr/ucb' early in your `PATH'. This directory contains several dysfunctional programs; working variants of these programs are available in `/usr/bin'. So, if you need `/usr/ucb' in your `PATH', put it _after_ `/usr/bin'. On Haiku, software installed for all users goes in `/boot/common', not `/usr/local'. It is recommended to use the following options: ./configure --prefix=/boot/common Specifying the System Type ========================== There may be some features `configure' cannot figure out automatically, but needs to determine by the type of machine the package will run on. Usually, assuming the package is built to be run on the _same_ architectures, `configure' can figure that out, but if it prints a message saying it cannot guess the machine type, give it the `--build=TYPE' option. TYPE can either be a short name for the system type, such as `sun4', or a canonical name which has the form: CPU-COMPANY-SYSTEM where SYSTEM can have one of these forms: OS KERNEL-OS See the file `config.sub' for the possible values of each field. If `config.sub' isn't included in this package, then this package doesn't need to know the machine type. If you are _building_ compiler tools for cross-compiling, you should use the option `--target=TYPE' to select the type of system they will produce code for. If you want to _use_ a cross compiler, that generates code for a platform different from the build platform, you should specify the "host" platform (i.e., that on which the generated programs will eventually be run) with `--host=TYPE'. Sharing Defaults ================ If you want to set default values for `configure' scripts to share, you can create a site shell script called `config.site' that gives default values for variables like `CC', `cache_file', and `prefix'. `configure' looks for `PREFIX/share/config.site' if it exists, then `PREFIX/etc/config.site' if it exists. Or, you can set the `CONFIG_SITE' environment variable to the location of the site script. A warning: not all `configure' scripts look for a site script. Defining Variables ================== Variables not defined in a site shell script can be set in the environment passed to `configure'. However, some packages may run configure again during the build, and the customized values of these variables may be lost. In order to avoid this problem, you should set them in the `configure' command line, using `VAR=value'. For example: ./configure CC=/usr/local2/bin/gcc causes the specified `gcc' to be used as the C compiler (unless it is overridden in the site shell script). Unfortunately, this technique does not work for `CONFIG_SHELL' due to an Autoconf bug. Until the bug is fixed you can use this workaround: CONFIG_SHELL=/bin/bash /bin/bash ./configure CONFIG_SHELL=/bin/bash `configure' Invocation ====================== `configure' recognizes the following options to control how it operates. `--help' `-h' Print a summary of all of the options to `configure', and exit. `--help=short' `--help=recursive' Print a summary of the options unique to this package's `configure', and exit. The `short' variant lists options used only in the top level, while the `recursive' variant lists options also present in any nested packages. `--version' `-V' Print the version of Autoconf used to generate the `configure' script, and exit. `--cache-file=FILE' Enable the cache: use and save the results of the tests in FILE, traditionally `config.cache'. FILE defaults to `/dev/null' to disable caching. `--config-cache' `-C' Alias for `--cache-file=config.cache'. `--quiet' `--silent' `-q' Do not print messages saying which checks are being made. To suppress all normal output, redirect it to `/dev/null' (any error messages will still be shown). `--srcdir=DIR' Look for the package's source code in directory DIR. Usually `configure' can determine that directory automatically. `--prefix=DIR' Use DIR as the installation prefix. *note Installation Names:: for more details, including other options available for fine-tuning the installation locations. `--no-create' `-n' Run the configure checks, but stop before creating any output files. `configure' also accepts some other, not widely useful, options. Run `configure --help' for more details. pgpool-II-4.6.1/NEWS0000644000175000017500000153567115010601344010755 00000000000000 Release Notes =============================================================================== 3.6 Series (201x/xx/xx - ) =============================================================================== 3.6.0 (subaruboshi) 201x/xx/xx * Version 3.6.0 This is the first version of pgpool-II 3.6 series. That is, a "major version up" from 3.5 series. * Overview Major enhancements in Pgpool-II 3.6 include: - Improve the behavior of fail-over. In the steaming replication mode, client sessions will not be disconnected when a fail-over occurs any more if the session does not use the failed standby server. If the primary server goes down, still all sessions will be disconnected. Also it is possible to connect to Pgpool-II even if it is doing health checking retries. Before all attempt of connecting to Pgpool-II failed while doing health checking retries. - New PGPOOL SET command has been introduced. Certain configuration parameters now can be changed on the fly in a session. - Watchdog is significantly enhanced. It becomes more reliable than previous releases. - Handling of extended query protocol (e.g. used by Java applications) in streaming replication mode speeds up if many rows are returned in a result set. - Import parser of PostgreSQL 9.6. - In some cases pg_terminate_backend() now does not trigger a fail-over. - Change documentation format from raw HTML to SGML. The above items are explained in more detail in the sections below. * Major Enhancements - Improve the behavior of fail-over. (Tatsuo Ishii) In the steaming replication mode, client sessions will not be disconnected when a fail-over occurs any more if the session does not use the failed standby server. If the primary server goes down, still all sessions will be disconnected. Health check timeout case will also cause the full session disconnection. Other health check error, including retry over case does not trigger full session disconnection. For user's convenience, "show pool_nodes" command shows the session local load balance node info since this is important for users in case of fail-over. If the load balance node is not the failed node, the session will not be affected by fail-over. Also now it is possible to connect to Pgpool-II even if it is doing health checking retries. Before all attempt of connecting to Pgpool-II failed while doing health checking retries. Before any attempt to connect to Pgpool-II fails if it is doing a health check against failed node even if fail_over_on_backend_error is off because Pgpool-II child first tries to connect to all backend including the failed one and exits if it fails to connect to a backend (of course it fails). This is a temporary situation and will be resolved before pgpool executes fail-over. However if the health check is retrying, the temporary situation keeps longer depending on the setting of health_check_max_retries and health_check_retry_ delay. This is not good. Attached patch tries to mitigate the problem: When an attempt to connect to backend fails, give up connecting to the failed node and skip to other node, rather than exiting the process if operating in streaming replication mode and the node is not primary node. Mark the local status of the failed node to "down". This will let the primary node be selected as a load balance node and every queries will be sent to the primary node. If there's other healthy standby nodes, one of them will be chosen as the load balance node. After the session is over, the child process will suicide to not retain the local status. - Add PGPOOL SHOW, PGPOOL SET and PGPOOL RESET commands. (Muhammad Usama) These are similar to the PostgreSQL's SET and SHOW commands for GUC variables, adding the functionality in Pgpool-II to set and reset the value of config parameters for the current session, and for that it adds a new syntax in Pgpool-II which is similar to PostgreSQL's SET and RESET variable syntax with an addition of PGPOOL keyword at the start. Currently supported configuration parameters by PGPOOL SHOW/SET/RESET are: log_statement, log_per_node_statement, check_temp_table, check_unlogged_ table, allow_sql_comments, client_idle_limit, log_error_verbosity, client_min_messages, log_min_messages, client_idle_limit_in_recovery. - Sync inconsistent status of PostgreSQL nodes in Pgpool-II instances after restart. (Muhammad Usama) - At the Pgpool-II startup, the status of each configured backend node is loaded from the backend status file or otherwise initialized by querying the backend nodes. This technique works fine in stand alone mode and also with the watchdog enabled as long as the status of backend nodes remains consistent until all Pgpool-II nodes got up and running. But since Pgpool-II does not sync the backend node status from the watchdog cluster at startup time, so in some cases the Pgpool-II nodes participating in the watchdog cluster may get a different status for the same backend, especially if the Pgpool-II nodes part of the watchdog cluster starts at different times and between that time an unavailable backend PostgreSQL node had become available again. So to solve this, the commit implements the new startup procedure for the standby Pgpool-II, And now the standby Pgpool-II will load the backend status of all configured PostgreSQL nodes from the watchdog master/coordinator node at the time of startup. - Enhance performance of SELECT when lots of rows involved. (Tatsuo Ishii) Pgpool-II flushes data to network (calling write(2)) every time it sends a row data ("Data Row" message) to frontend. For example, if 10,000 rows needed to be transfer, 10,000 times write()s are issued. This is pretty expensive. Since after repeating to send row data, "Command Complete" message is sent, it's enough to issue a write() with the command complete message. Also there are unnecessary flushing are in handling the command complete message. Quick testing showed that from 47% to 62% performance enhancements were achieved in some cases. Unfortunately, performance in workloads where transferring few rows, will not be enhanced since such rows are needed to flush to network anyway. - Import PostgreSQL 9.6's SQL parser. (Bo Peng) This allows Pgpool-II to fully understand the newly added SQL syntax such as COPY INSERT RETURNING. - In some cases pg_terminate_backend() now does not trigger a fail-over. (Muhammad Usama) Since the pg_terminate_backend function in PostgreSQL is used to terminate the backend connection, So what happens is, when this function kills a PostgreSQL backend that is connected to the Pgpool-II, This disconnection of backend by pg_terminate_backend function is appeared as a backend node failure to the Pgpool-II. But the problem here is, PostgreSQL does not give any information to the client program that the connection is going to be killed because of the pg_terminate_backend call and on the client side, it looks similar to the backend node failure. Now to solve this in Pgpool-II we need two things. First is to identify the pg_terminate_backend function in the query and the Pgpool-II child process that hosts the particular backend connection which will be killed by that pg_terminate_backend function call, so that we get a heads up in advance about the backend termination, and secondly the routing of the query containing pg_terminate_backend also needs a new logic so that the query should be sent to the correct PostgreSQL node that hosts the backend with the PID referred by the pg_terminate_backend() So how does this commit handles pg_terminate_backend()?? In the SimpleQuery() function which is the work horse of simple query processing in the Pgpool-II we start with the search of the pg_terminate_backend() function call in the query parse tree and if the search comes out to be successful, the next step is to locate the Pgpool-II child process and a backend node of that connection whose PID is specified in pg_terminate_backend function's argument. Once the connection and the Pgpool-II child process is identified, we just set the swallow_termination flag(added by this commit in ConnectionInfo structure) for that connection in the shared memory, and also set the query destination node to the backend node that hosts that particular connection and does not call pool_where_to_send() for this query so that the query should be sent to the correct backend node. Now when the query is routed to the correct node and consequently the backend gets killed, that results in the communication error on Pgpool-II side, the Pgpool-II already knows that this disconnection is due the pg_terminate_backend and not because of node failure as the swallow_termination flag is already set for the connection. Some works are still remaining. pg_terminate_backend is not handled with extended query protocol. Currently we only support pg_terminate_backend(constant number) function calls. If the expression or sub query is used in the argument of pg_terminate_backend then it would not be handled e.g pgpool=# select pg_terminate_backend(1025); -- Supported pgpool=# select pg_terminate_backend( 2 +1); -- NOT SUPPORTED pgpool=# select pg_terminate_backend((select 1)); -- NOT SUPPORTED Currently only one pg_terminate_backend call in a query is handled. - HTML documents are now generated from SGML documents. (Muhammad Usama, Tatsuo Ishii, Bo Peng) It is intended to have better construction, contents and maintainability. However, still there's tremendous room to enhance the SGML documents. Please help us! * Other Enhancements - Make authentication error message more user friendly. (Tatsuo Ishii) When attempt to connect to backend (including health checking), emit error messages from backend something like "sorry, too many clients already" instead of "invalid authentication message response type, Expecting 'R' and received '%c'" - Tighten up health check timer expired condition in pool_check_fd(). (Muhammad Usama) Check if the signal was actually the health check timer expire to make sure that we do not declare the timer expire due to some other signal arrived while waiting for data for health check in pool_check_fd(). - Add new script called "watchdog_setup". (Tatsuo Ishii) watchdog_setup is a command to create a temporary installation of Pgpool-II clusters with watchdog for mainly testings. Add "-pg" option to pgpool_setup. (Tatsuo Ishii) This is useful when you want to assign specific port numbers to PostgreSQL while using pgpool_setup. Also now pgpool_setup is installed in the standard bin directory which is same as pgpool. - Add "replication delay" column to "show pool_nodes". (Tatsuo Ishii) This column shows the replication delay value in bytes if operated in streaming replication mode. - Do not update status file if all backend nodes are in down status. (Chris Pacejo, Tatsuo Ishii) This commit tries to remove the data inconsistency in replication mode found in [pgpool-general: 3918] by not recording the status file when all backend nodes are in down status. This surprisingly simple but smart solution was provided by Chris Pacejo. - Allow to use multiple SSL cipher protocols. (Multiple Usama) By replacing TLSv1_method() with SSLv23_method() while initializing the SSL session, we can use more protocols than TLSv1 protocol. Allow to use arbitrary number of items in the black_function_list/white_function_list. (Muhammad Usama) Previously there were fixed limits for those. - Properly process empty queries (all comments). (Tatsuo Ishii) Pgpool-II now recognizes an empty query consisted of all comments (for example "/* DBD::Pg ping test v3.5.3 */") (note that no ';') as an empty query. Before such that query was recognized an error. Add some warning messages for wd_authkey hash calculation failure. (Yugo Nagata) Sometimes wd_authkey calculation fails for some reason other than authkey mismatch. The additional messages make these distinguishable for each other. * Changes - Change the default value of search_primary_node_timeout from 10 to 300. (Tatsuo Ishii) Prior default value 10 seconds is sometimes too short for a standby to be promoted. - Change the Makefile under directory src/sql/, that is proposed by [pgpool-hackers: 1611]. (Bo Peng) - Change the PID length of pcp_proc_count command output to 6 characters long. (Bo Peng) If the Pgpool-II process ID are over 5 characters, the 6th character of each process ID will be removed. This commit changes the process ID length of pcp_proc_count command output to 6 characters long. - Redirect all user queries to primary server. (Tatsuo Ishii) Up to now some user queries are sent to other than the primary server even if load_balance_mode = off. This commit changes the behavior: if load_balance_mode = off in streaming replication mode, now all the user queries are sent to the primary server only. * Bug fixes - Fix the case when all backends are down then 1 node attached. (Tatsuo Ishii) When all backends are down, no connection is accepted. Then 1 PostgreSQL becomes up, and attach the node using pcp_attach_node. It successfully finishes. However, when a new connection arrives, still the connection is refused becausePgpool-II child process looks into the cached status, in which the recovered node is still in down status if mode is streaming replication mode (native replication and other modes are fine). Solution is, if all nodes are down, force to restart all pgpool child. - Fix for avoiding downtime when Pgpool-II changes require a restart. (Muhammad Usama) To fix this, The verification mechanism of configuration parameter values is reversed, previously the standby nodes used to verify their parameter values against the respective values on the master Pgpool-II node and when the inconsistency was found the FATAL error was thrown, now with this commit the verification responsibility is delegated to the master Pgpool-II node. Now the master node will verify the configuration parameter values of each joining standby node against its local values and will produce a WARNING message instead of an error in case of a difference. This way the nodes having the different configurations will also be allowed to join the watchdog cluster and the user has to manually look out for the configuration inconsistency warnings in the master Pgpool-II log to avoid the surprises at the time of Pgpool-II master switch over. - Fix a problem with the watchdog failover_command locking mechanism. (Muhammad Usama) From Pgpool-II 3.5 watchdog was using the separate individual locks for each node-failover command (failover, failback and follow-master) and the lock was acquired just before executing the respective failover script and was released as soon as the script execution finishes. This technique although was very efficient but also had a problem. If the failover_command takes a very little time and gets finished before the lock request from other Pgpool-II node arrives, the other node is also granted a lock, since the lock was already released by the first node at that time. Consequently, both nodes ends up executing the failover script. So to fix this we are reverting back to the tested failover interlocking design used prior to Pgpool-II 3.5 where all the commands gets locked at the failover start by the node that becomes a lock-holder and each command lock is released after its execution finishes. And only the lock-holder node is allowed to acquire/release the individual command lock. That way the lock-holder node keeps the lock-holder status throughout the span of the failover execution and the system becomes less time sensitive. - Disable strict aliasing optimization. (Tatsuo Ishii) flatten_set_variable_args() was imported from PostgreSQL in Pgpool-II 3.5. To make the code work, a compiler flag -fno-strict-aliasing is necessary (PostgreSQL does so). Unfortunately when the function was imported, the compiler flag was not added. To fix this, configure.ac was modified. - Do not use random() while generating MD5 salt. (Tatsuo Ishii) random() should not be used in security related applications. To replace random(), import PostmasterRandom() from PostgreSQL. Also store current time at the start up of Pgpool-II main process for later use. - Don't ignore sync message from frontend when query cache is enabled. (Tatsuo Ishii) While returning cached query result, sync message sent from frontend is discarded. This is harmless because "ready for query" messages is sent to frontend afterward. Problem is, AccessShareLock held by previous parse message processing is not released until sync message is received by the backend. Fix is, forwarding the sync message to backend and discarding "ready for query" message returned from backend. - Fix bug that Pgpool-II fails to start if listen_addresses is empty string. (bug 237) (Muhammad Usama) The socket descriptor array (fds[]) was not getting the array end marker when TCP listen addresses are not used. - Create regression log directory if it does not exist yet. (Tatsuo Ishii) - Fixing the error messages when the socket operation fails. (Muhammad Usama) When some socket operation fails, we issue close socket before throwing an error which causes the errno value to be overwritten and consequently the error log does not print the correct failure reason. The solution is to save the errno before closing the socket and use the saved value to print error description. - Fix regression failure of 003.failover. (Tatsuo Ishii) Update expected data to reflect the changes made to show pool_nodes. Also fix show pool_nodes to proper use "_" instead of space for the column name. - Fix hang when portal suspend received. (bug 230) (Tatsuo Ishii) When portal suspend message is received, it's not enough to forward it to the client. Since backend expects to receive execute message, trying to read further more messages from backend will never succeed. To fix this, turn off the query in progress flag, which will pole incoming message from the client. - Fix pgpool doesn't de-escalate IP in case network restored. (bug 228) (Muhammad Usama) set_state function is made to de-escalate, when it is changing the local node's state from the coordinator state to some other state. - SIGUSR1 signal handler should be installed before watchdog initialization. (Muhammad Usama) Since there can be a case where a failover request from other watchdog nodes arrive at the same time when the watchdog has just been initialized, and if we wait any longer to install a SIGUSR1 signal handler, it can result in a potential crash - Fix for bug of inconsistent status of PostgreSQL nodes in Pgpool-II instances after restart. (bug 218) (Muhammad Usama) Watchdog does not synchronize status. Currently at the Pgpool-II startup, The status of each configured backend node is loaded from the backend status file or otherwise initialized by querying the backend nodes. This technique works fine in stand alone mode and also with the watchdog enabled as long as the status of backend nodes remains consistent until all Pgpool-II nodes got up and running. But since Pgpool-II does not sync the backend node status from the watchdog cluster at startup time, so in some cases the pgpool-II nodes participating in the watchdog cluster may get a different status for the same backend, especially if the Pgpool-II nodes part of the watchdog cluster starts at different times and between that time an unavailable backend PostgreSQL node had become available again. So to solve this, the commit implements the new startup procedure for the standby Pgpool-II, And now the standby Pgpool-II will load the backend status of all configured PostgreSQL nodes from the watchdog master/coordinator node at the time of startup. - Fix Pgpool-II doesn't escalate ip in case of another node unavailability. (bug 215) (Muhammad Usama) The heartbeat receiver fails to identify the heartbeat sender watchdog node when the heartbeat destination is specified in terms of an IP address while wd_hostname is configured as a hostname string or vice versa. - Fixing a coding mistake in watchdog code. (Muhammad Usama) wd_issue_failover_lock_command() function is supposed to forward command type passed in as an argument to the wd_send_failover_sync_command() function instead it was passing the NODE_FAILBACK_CMD command type. The commit also contains some log message enhancements. - Display human readable output for backend node status. (Muhammad Usama) Changed the output of pcp_node_info utility and show commands display human readable backend status string instead of internal status code. - Replace "MAJOR" macro to prevent occasional failure. (Tatsuo Ishii) The macro calls pool_virtual_master_db_node_id() and then access backend->slots[id]->con using the node id returned. In rare cases, it could point to 0 (in case when the DB node is not connected), which gives access to con->major, then it causes a segfault. - Fix "kind mismatch" error message in Pgpool-II. (Muhammad Usama) Many of "kind mismatch..." errors are caused by notice/warning messages produced by one or more of the DB nodes. In this case now Pgpool-II forwards the messages to frontend, rather than throwing the "kind mismatch..." error. This would reduce the chance of "kind mismatch..." errors. - Fix handling of pcp_listen_addresses config parameter. (Muhammad Usama) - Save and restore errno in each signal handler. (Tatsuo Ishii) - Fix usage of wait(2) in pgpool main process. (Tatsuo Ishii) When child process dies, SIGCHLD signal is raised and wait(2) knows the event. However, multiple child death does not necessarily creates exact same number of SIGCHLD signal as the number of dead children and wait(2) could wait for an event which never happens in this case. I Actually encountered this situation while testing Pgpool-II. Solution is, to use waitpid(2) instead of wait(2). - Fix confusing error messages. (Tatsuo Ishii) pool_read() does not emit error messages when read(2) returns -1 if fail_over_on_backend_error is off. In any case the cause of error should be emitted. I do not back port this because it's a too trivial enhancement. - Fix buffer over run problem in "show pool_nodes". (Tatsuo Ishii) While processing "show pool_nodes", the buffer for hostname was too short. It should be same size as the buffer used for pgpool.conf. Problem reported by a twitter user who is using pgpool on AWS (which could have very long hostname). - Fix [pgpool-hackers: 1638] pgpool-II does not use default configuration. (Muhammad Usama) Configuration file not found should just throw a WARNING message instead of ERROR or FATAL. - Fix bug with load balance node id info on shmem. (Tatsuo Ishii) There are few places where the load balance node was mistakenly put on wrong place. It should be placed on: ConnectionInfo *con_info[child id, connection pool_id, backend id].load_balancing_node]. In fact it was placed on: *con_info[child id, connection pool_id, 0].load_balancing_node]. As long as the backend id in question is 0, it is ok. However while testing Pgpool-II 3.6's enhancement regarding failover, if primary node is 1 (which is the load balance node) and standby is 0, a client connecting to node 1 is disconnected when failover happens on node 0. This is unexpected and the bug was revealed. It seems the bug was there since long time ago but it had not found until today by the reason above. - Fix for bug that pgpool hangs connections to database. (bug 197) (Muhammad Usama) The client connection was getting stuck when backend node and remote Pgpool-II node becomes unavailable at the same time. The reason was a missing command timeout handling in the function that sends the IPC commands to watchdog. - Fix a possible hang during health checking. (bug 204) (Yugo Nagata) Health checking was hang when any data wasn't sent from backend after connect(2) succeeded. To fix this, pool_check_fd() returns 1 when select(2) exits with EINTR due to SIGALRM while health checking is performed. - Deal with the case when the primary is not node 0 in streaming replication mode. (Tatsuo Ishii) http://www.pgpool.net/mantisbt/view.php?id=194#c837 reported that if primary is not node 0, then statement timeout could occur even after bug194-3.3.diff was applied. After some investigation, it appeared that MASTER macro could return other than primary or load balance node, which was not supposed to happen, thus do_query() sends queries to wrong node (this is not clear from the report but I confirmed it in my investigation). pool_virtual_master_db_node_id(), which is called in MASTER macro returns query_context->virtual_master_node_id if query context exists. This could return wrong node if the variable has not been set yet. To fix this, the function is modified: if the variable is not either load balance node or primary node, the primary node id is returned. For master and 3.5-stable, additional fixes/enhancements are made: pool_extended_send_and_wait() now issues flush message if the request is 'E' (execute). Before it was issued outside (in Execute), but this makes the logic to determine to which node the flush message to be sent unnecessary complex. A debug message in pool_write is enhanced by adding backend node id. - If statement timeout is enabled on backend and do_query() sends a query to primary node, and all of following user queries are sent to standby, it is possible that the next command, for example END, could cause a statement timeout error on the primary, and a kind mismatch error on pgpool-II is raised. (bug 194) (Tatsuo Ishii) This fix tries to mitigate the problem by sending sync message instead of flush message in do_query(), expecting that the sync message reset the statement timeout timer if we are in an explicit transaction. We cannot use this technique for implicit transaction case, because the sync message removes the unnamed portal if there's any. Plus, pg_stat_statement will no longer show the query issued by do_query() as "running". - Fix extended protocol handling in raw mode. (Tatsuo Ishii) Bug152 reveals that extended protocol handling in raw mode (actually other than in stream mode) was wrong in Describe() and Close(). Unlike stream mode, they should wait for backend response. - Fix confusing comments in pgpool.conf. (Tatsuo Ishii) - Fix Japanese and Chinese documentation bug about raw mode. (Yugo Nagata, Bo Peng) Connection pool is available in raw mode. - Fix is_set_transaction_serializable() when SET default_transaction_isolation TO 'serializable'. (bug 191) (Bo Peng) SET default_transaction_isolation TO 'serializable' is sent to not only primary but also to standby server in streaming replication mode, and this causes an error. Fix is, in streaming replication mode, SET default_transaction_isolation TO 'serializable' is sent only to the primary server. - Fix extended protocol hang with empty query. (bug 190) (Tatsuo Ishii) The fixes related to extended protocol cases in 3.5.1 broke the case of empty query. In this case backend replies with "empty query response" which is same meaning as a command complete message. Problem is, when empty query response is received, pgpool does not reset the query in progress flag thus keeps on waiting for backend. However, backend will not send the ready for query message until it receives a sync message. Fix is, resetting the in progress flag after receiving the empty query response and reads from frontend expecting it sends a sync message. - Fix for [pgpool-general: 4569] Pgpool-II 3.5 : segfault. (Muhammad Usama) PostgreSQL's memory and exception manager APIs adopted by the Pgpool-II 3.4 are not thread safe and are causing the segmentation fault in the watchdog lifecheck process, as it uses the threads to ping configured trusted hosts for checking the upstream connections. Fix is to remove threads and use the child process approach instead. - Validating the PCP packet length. (Muhammad Usama) Without the validation check, a malformed PCP packet can crash the PCP child and/or can run the server out of memory by sending the packet with a very large data size. - Fix Pgpool-II hang bug (bug 167). (Tatsuo Ishii) Pgpool-II 3.5 or after in streaming replication mode does not wait for response from each phase such parse, bind anymore. However, if do_query is called, it sends flush message to retrieve the result of system catalog look up. This is only sent to primary node which may results in retrieving previous message results, for example parse complete. If standby is assigned to load balance node, the node does not return parse complete message, which will cause a problem in bug167 case, because parse message for "BEGIN" was sent to both the primary and the standby. Fix is, send flush message in do_query if the load balance node is one of standbys. - Fix pgpool_setup to not confuse log output. (Tatsuo Ishii) Before it simply redirects the stdout and stderr of pgpool process to a log file. This could cause log contents being garbled or even missed because of race condition caused by multiple process being writing concurrently. I and Usama found this while investigating the regression failure of 004.watchdog. To fix this, pgpool_setup now generates startall script so that pgpool now sends stdout/stderr to cat command and cat writes to the log file (It seems the race condition does not occur when writing to a pipe). - Fix for [pgpool-general: 4519] Worker Processes Exit and Are Not Re-spawned. (Muhammad Usama) The problem was due to a logical mistake in the code for checking the exiting child process type when the watchdog is enabled. I have also changed the severity of the message from FATAL to LOG, emitted for child exits due to max connection reached. - Fix pgpool hung after receiving error state from backend. (bug #169) (Tatsuo Ishii) This could happen if we execute an extended protocol query and it fails. After an error is received the "ignore till sync flag" is set and retained even if sync message was actually received. Thus any subsequent query (in the case above "DEALLOCATE message") is not processed and pgpool waits for message from frontend and backend, and pgpool sticks here because no message will arrive from both side. To fix this, unconditionally reset the "ignore till sync flag" in ReadyforQuery(). This is safe because apparently we already received the ready for query message. - Fix query stack problems in extended protocol case. (bug 167, 168) (Tatsuo Ishii) - Fix [pgpool-hackers: 1440] yet another reset query stuck problem. (Tatsuo Ishii) After receiving X message from frontend, if Pgpool-II detects EOF on the connection before sending reset query, Pgpool-II could wait for backend which had not received the reset query. To fix this, if EOF received, treat this as FRONTEND_ERROR, rather than ERROR. - Fix for [pgpool-general: 4265] another reset query stuck problem. (Muhammad Usama) The solution is to report FRONTEND_ERROR instead of simple ERROR when pool_flush on front-end socket fails. - Fixing pgpool-recovery module compilation issue with PostgreSQL 9.6. (Muhammad Usama) Incorporating the change of function signature for GetConfigOption() functions in PostgreSQL 9.6 - Fix compile issue on freebsd. (Muhammad Usama) Add missing include files. The patch is contributed by the bug reporter and enhanced a little by me. - Fix regression test to check timeout of each test. (Yugo Nagata) - Add some warning messages for wd_authkey hash calculation failure. (Yugo Nagata) Sometimes wd_authkey calculation fails for some reason other than authkey mismatch. The additional messages make these distinguishable for each other. =============================================================================== 3.5 Series (2016/01/29 - ) =============================================================================== 3.5.4 (ekieboshi) 2016/08/31 * Version 3.5.4 This is a bugfix release against pgpool-II 3.5.3. __________________________________________________________________ * Bug fixes - Fix buffer over run problem in "show pool_nodes". (Tatsuo Ishii) While processing "show pool_nodes", the buffer for hostname was too short. It should be same size as the buffer used for pgpool.conf. Problem reported by a twitter user who is using pgpool on AWS (which could have very long hostname). - Fix usage of wait(2) in pgpool main process. (Tatsuo Ishii) The usage of wait(2) in pgpool main could cause infinite wait in the system call. Solution is, to use waitpid(2) instead of wait(2). - Save and restore errno in each signal handler. (Tatsuo Ishii) - Fix handling of pcp_listen_addresses config parameter. (Muhammad Usama) - Fix "kind mismatch" error message in pgpool. (Muhammad Usama) Many of "kind mismatch..." errors are caused by notice/warning messages produced by one or more of the DB nodes. In this case now Pgpool-II forwards the messages to frontend, rather than throwing the "kind mismatch..." error. This would reduce the chance of "kind mismatch..." errors.

(Muhammad Usama) The socket descriptor array (fds[]) was not getting the array end marker when TCP listen addresses are not used. See bug 237 for related info. =============================================================================== 3.5.3 (ekieboshi) 2016/06/17 * Version 3.5.3 This is a bugfix release against pgpool-II 3.5.2. __________________________________________________________________ * New features - Allow to access to pgpool while doing health checking (Tatsuo Ishii) Currently any attempt to connect to pgpool fails if pgpool is doing health check against failed node even if fail_over_on_backend_error is off because pgpool child first tries to connect to all backend including the failed one and exits if it fails to connect to a backend (of course it fails). This is a temporary situation and will be resolved before pgpool executes failover. However if the health check is retrying, the temporary situation keeps longer depending on the setting of health_check_max_retries and health_check_retry_delay. This is not good. Attached patch tries to mitigate the problem: - When an attempt to connect to backend fails, give up connecting to the failed node and skip to other node, rather than exiting the process if operating in streaming replication mode and the node is not primary node. - Mark the local status of the failed node to "down". - This will let the primary node be selected as a load balance node and every queries will be sent to the primary node. If there's other healthy standby nodes, one of them will be chosen as the load balance node. - After the session is over, the child process will suicide to not retain the local status. Per [pgpool-hackers: 1531]. * Bug fixes - Fix is_set_transaction_serializable() when SET default_transaction_isolation TO 'serializable'. (Bo Peng) SET default_transaction_isolation TO 'serializable' is sent to not only primary but also to standby server in streaming replication mode, and this causes an error. Fix is, in streaming replication mode, SET default_transaction_isolation TO 'serializable' is sent only to the primary server. See bug 191 for related info. - Fix Chinese documentation bug about raw mode (Yugo Nagata, Bo Peng) Connection pool is available in raw mode. - Fix confusing comments in pgpool.conf (Tatsuo Ishii) - Fix extended protocol handling in raw mode (Tatsuo Ishii) Bug152 reveals that extended protocol handling in raw mode (actually other than in stream mode) was wrong in Describe() and Close(). Unlike stream mode, they should wait for backend response. See bug 152 for related info. - Permit pgpool to support multiple SSL cipher protocols (Muhammad Usama) Currently TLSv1_method() is used to initialize the SSL context, that puts an unnecessary limitation to allow only TLSv1 protocol for SSL communication. While postgreSQL supports other ciphers protocols as well. The commit changes the above and initializes the SSLSession using the SSLv23_method() (same is also used by PostgreSQL). Because it can negotiate the use of the highest mutually supported protocol version and remove the limitation of one specific protocol version. - If statement timeout is enabled on backend and do_query() sends a (Tatsuo Ishii) query to primary node, and all of following user queries are sent to standby, it is possible that the next command, for example END, could cause a statement timeout error on the primary, and a kind mismatch error on pgpool-II is raised. This fix tries to mitigate the problem by sending sync message instead of flush message in do_query(), expecting that the sync message reset the statement timeout timer if we are in an explicit transaction. We cannot use this technique for implicit transaction case, because the sync message removes the unnamed portal if there's any. Plus, pg_stat_statement will no longer show the query issued by do_query() as "running". See bug 194 for related info. - Deal with the case when the primary is not node 0 in streaming replication mode. (Tatsuo Ishii) http://www.pgpool.net/mantisbt/view.php?id=194#c837 reported that if primary is not node 0, then statement timeout could occur even after bug194-3.3.diff was applied. After some investigation, it appeared that MASTER macro could return other than primary or load balance node, which was not supposed to happen, thus do_query() sends queries to wrong node (this is not clear from the report but I confirmed it in my investigation). pool_virtual_master_db_node_id(), which is called in MASTER macro returns query_context->virtual_master_node_id if query context exists. This could return wrong node if the variable has not been set yet. To fix this, the function is modified: if the variable is not either load balance node or primary node, the primary node id is returned. - Fix a possible hang during health checking (Yugo Nagata) Health checking was hang when any data wasn't sent from backend after connect(2) succeeded. To fix this, pool_check_fd() returns 1 when select(2) exits with EINTR due to SIGALRM while health checking is performed. Reported and patch provided by harukat and some modification by Yugo. See bug 204 for related info. - change the Makefile under this directory src/sql/,that is proposed by (Bo Peng) [pgpool-hackers: 1611] - fix for 0000197: pgpool hangs connections to database.. (Muhammad Usama) The client connection was getting stuck when backend node and remote pgpool-II node becomes unavailable at the same time. The reason was a missing command timeout handling in the function that sends the IPC commands to watchdog. - Fix bug with load balance node id info on shmem (Tatsuo Ishii) There are few places where the load balance node was mistakenly put on wrong place. It should be placed on: ConnectionInfo *con_info[child id, connection pool_id, backend id].load_balancing_node]. In fact it was placed on: *con_info[child id, connection pool_id, 0].load_balancing_node]. As long as the backend id in question is 0, it is ok. However while testing pgpool-II 3.6's enhancement regarding failover, if primary node is 1 (which is the load balance node) and standby is 0, a client connecting to node 1 is disconnected when failover happens on node 0. This is unexpected and the bug was revealed. It seems the bug was there since long time ago but it had not found until today by the reason above. - Fixing coverity scan reported issues. (Muhammad Usama) =============================================================================== 3.5.2 (ekieboshi) 2016/04/26 * Version 3.5.2 This is a bugfix release against pgpool-II 3.5.1. __________________________________________________________________ * Bug fixes - Fix for segfault during trusted_servers check (Muhammad Usama) PostgreSQL's memory and exception manager APIs adopted by the pgpool 3.4 are not thread safe and are causing the segmentation fault in the watchdog lifecheck process, as it uses the threads to ping configured trusted hosts for checking the upstream connections. Fix is to remove threads and use the child process approach instead. See [pgpool-general: 4569] for more details. - Removing the limit on the maximum number of items in the black_function_list and white_function_list lists (Muhammad Usama) extract_string_tokens in pool_config uses the fixed size malloc on the array to hold the black_function_list/white_function_list items. This imposes a limit of maximum items in these lists. The fix is to use realloc to increase the array size when it gets full. - Fix check "PCP Directory" in "Parameter Setting" in install (Nozomi Anzai) The command "pcp_system_info" was discarded in 3.5, but pgpoolAdmin still confirmed if it existed. Per bug #187. - Fix extended protocol hang with empty query (Tatsuo Ishii) The fixes related to extended protocol cases in 3.5.1 broke the case of empty query. In this case backend replies with "empty query response" which is same meaning as a command complete message. Problem is, when empty query response is received, pgpool does not reset the query in progress flag thus keeps on waiting for backend. However, backend will not send the ready for query message until it receives a sync message. Fix is, resetting the in progress flag after receiving the empty query response and reads from frontend expecting it sends a sync message. Per bug #190. - Redirect all user queries to primary server (Tatsuo Ishii) Up to now some user queries are sent to other than the primary server even if load_balance_mode = off. This commit changes the behavior: if load_balance_mode = off in streaming replication mode, now all the user queries are sent to the primary server only. Per bug #189. - Change the PID length of pcp_proc_count command result to 6 characters long (Bo Peng) If the pgpool process ID are over 5 characters, the 6th character of each process ID will be removed. This commit changes the process ID length of pcp_proc_count command result to 6 characters long. Per bug #188. =============================================================================== 3.5.1 (ekieboshi) 2016/04/04 * Version 3.5.1 This is a bugfix release against pgpool-II 3.5.0. __________________________________________________________________ * Bug fixes - Add some warning messages for wd_authkey hash calculation failure (Yugo Nagata) Sometimes wd_authkey calculation fails for some reason other than authkey mismatch. The additional messages make these distinguishable for each other. - test: Fix regression test to check timeout of each test (Yugo Nagata) - test: Allow timeout value to be specified by the command option (Yugo Nagata) - Fix compile issue on FreeBSD (Muhammad Usama) Added missing include files. Per bug #166. The patch is contributed by the bug reporter and enhanced a little by Usama. - test: Fix test/regression/clean.sh to remove binary files of 010.rewrite_timestamp test (Yugo Nagata) - Fix memory leak reported by Coverity (CID 1350095) (Yugo Nagata) - Fixing pgpool-recovery module compilation issue with PostgreSQL 9.6 (Muhammad Usama) Incorporating the change of function signature for GetConfigOption..() functions in PostgreSQL 9.6. - Fix to properly process an empty query that has only comments (Tatsuo Ishii) Pgpool-II recognized an empty query, for example "/* DBD::Pg ping test v3.5.3 */" (note that it has no ';') as an error and emits message "Unable to parse the query". This is because raw_parser() cannot distinguish an empty query from an error query due to the poor API design. To fix this new out parameter "*error" added to the function. If an error occurred, the variable is set to true and caller can know the reason why raw_parser() returns NIL is because of an error query or an empty query. Per bug #154. See [pgpool-hackers: 1359] for additional information. - Fix a reset query stuck problem (Muhammad Usama) The solution is to report FRONTEND_ERROR instead of simple ERROR when pool_flush on front-end socket fails. The original report is [pgpool-general: 4265] Pgpool - connection hangs in DISCARD ALL The patch was generated by Usama and Pawel Ufnalewski, and Gerhard Wiesinger helped to verify and test the fix. - Fix a reset query stuck problem (Tatsuo Ishii) After receiving X message from frontend, if pgpool-II detects EOF on the connection before sending reset query, pgpool-II could wait for a response from backend which had not received the reset query. To fix this, if EOF received, treat this as FRONTEND_ERROR, rather than ERROR. See "[pgpool-hackers: 1440] Yet another reset query stuck problem" for more details. - Fix query stuck problems in streaming replication mode with extended protocol queries (Tatsuo Ishii) This fix is for both bug #167 and #168. - Fix pgpool hung after receiving error state from backend (Tatsuo Ishii) This could happened if we execute an extended protocol query and it fails. Per bug #169. - Fix bug that child processes exit and are not re-spawned (Muhammad Usama) The problem was due to a logical mistake in the code for checking the exiting child process type when the watchdog is enabled. Also the severity of the message emitted for child exits due to max connection reached from FATAL to LOG. Per [pgpool-general: 4519] Worker Processes Exit and Are Not Re-spawned - Fix typo in configure (Tatsuo Ishii) Patch provided by Thomas Munro. - doc: Change description of backend_flag (Tatsuo Ishii) It is pointed out that restarting pgpool-II is not necessary. Per [pgpool-general-jp: 1394]. - doc: Fix installation procedure. (Tatsuo Ishii) With PostgreSQL 9.4 or later, installing pgpool_regclass is not needed. - test: Fix pgpool_setup to not confuse log output (Tatsuo Ishii) Before it simply redirects stdout and stderr of pgpool processes to a log file. This could cause the log contents being garbled or even missed because of race condition caused by multiple process being writing concurrently. To fix this, pgpool_setup now generates startall script in which pgpool sends stdout/stderr to cat command by pipe, and cat writes to the log file. - Fix to validate the PCP packet length (Muhammad Usama) Without the validation check, a malformed PCP packet can crash the PCP child and/or can run the server out of memory by sending the packet with a very large data size. =============================================================================== 3.5.0 (ekieboshi) 2016/01/29 * Version 3.5.0 This is the first version of pgpool-II 3.5 series. That is, a "major version up" from 3.4 series. __________________________________________________________________ * Incompatible changes - Remove parallel query mode codes (Yugo Nagata) There are very few users and the maintenance efforts are not worth it. Codes for system db are also removed, since this was used in only parallel query mode and old query cache on disk. - Rename parameter name from ifconfig_path to if_cmd_path (Yugo Nagata) ifconfig_path isn't appropriate for the parameter name because ifconfig command is obsolete and now ip command is used as default. - Change the syntax of pcp commands arguments (Muhammad Usama) - Change the output and the argument semantics of pcp_watchdog_info command (Muhammad Usama) The command is enhanced to show watchdog information about all pgpool-II nodes in the cluster. According to this, the argument to specify node index is changed so that 0 means local pgpool-II node instead of the first remote node. __________________________________________________________________ * New features - Add new parameter "serialize_accept" (Tatsuo Ishii) This parameter defines whether to serialize accept() call for incoming client connections. Default is off, which means no serializing (same behavior as pgpool-II 3.4 or before). If this is off, the kernel wakes up all of pgpool-II child process to execute accept() and one of them actually accepts the incoming connection. Problem here is, because so my child process wake up at a same time, heavy context switching occurred and the performance is affected. This phenomena is a classic problem called "the thundering herd problem". By enabling serialize_accept, only one of pgpool-II child process is woken up and executes accept() and the problem can be avoided. - Import parser of PostgreSQL 9.5 (Yugo Nagata) pgpool-II can understand new syntax introduced in PostgreSQL 9.5 now. Especially GROUPING SET, CUBE, ROLLUP and TABLESAMPLE can be be load balanced and can be used in query cache (except for TABLESAMPLE). Also INSERT...ON CONFLICT and UPDATE tab SET (col1, col2, ...) = (SELECT ...) ... can now be properly handled in query rewriting in native replication mode. - Allow to specify database for health check and streaming replication delay check. (Tatsuo Ishii) For this purpose new directive "health_check_database" and "sr_check_database" are added. __________________________________________________________________ * Enhancements - Performance improvement in extended query protocol (Tatsuo Ishii) Unnecessary "flush" messages which used to be sent in each step of extended protocol messages (parse, bind, describe and execute) and brought significant communication overhead are removed. For now it only affects to streaming replication mode, that is, the performance of other modes remains same. - watchdog feature enhancements (Muhammad Usama, Yugo Nagata) The goal of this enhancement is to address the shortcomings and problems in the pgpool watchdog and make the watchdog system more robust and adaptable. Patch created by Usama, and reviewed, tested, and debugged by Yugo. -- The watchdog should consider the quorum and only elect the master/leader node if the quorum exist in the watchdog cluster. -- All the participating pgpool-II nodes in the watchdog cluster should have similar pgpool-II configurations. -- Watchdog nodes should have configurable watchdog node priority, to give users more control on which node should become a leader node. -- More options for the node health-checking, especially watchdog should allow external/3rd party node health checking system to integrate with it. -- The watchdog should keep looking for problems like split-brain syndrome and should automatically recover from it. -- Allow user to provide scripts to be executed at time of escalation and de-escalation to master/leader nodes. Add these new parameters: -- wd_ipc_socket_dir: This parameter is used to specify the directory where the UNIX domain socket accepting pgpool-II watchdog IPC connections will be created. -- wd_priority: This new parameter can be used to elevate the current watchdog node priority in leader elections. The node with the higher wd_priority value will get selected as master/coordinator watchdog node when cluster will be electing its master node at cluster startup or in the event of old master watchdog node failure. -- wd_de_escalation_command: This parameter holds the command that watchdog will execute on the master pgpool-II watchdog node when that node resigns from the master node responsibilities. -- wd_monitoring_interfaces_list: This parameter holds a comma separated list of network device names to be monitored by the watchdog process for the network link state. - Overhauling pcp commands (Muhammad Usama) -- Improved handling of command argument: Long command line options can be used now. -- PCP password is safe: Don't pass password via command line, which causes security risks. -- Multiple concurrent execution of pcp commands: Allow to execute a pcp command while running pcp_recovery_node which takes sometime to finish. - SELECT count statics in "show pool_nodes" command results (Tatsuo Ishii) show pool_nodes results which briefly describes the status of each backend now shows how many SELECTs are issued to them. So you can quickly recognize the effect of load balancing for example; test=# show pool_nodes; node_id | hostname | port | status | lb_weight | role | select_cnt ---------+----------+-------+--------+-----------+---------+------------ 0 | /tmp | 11002 | 2 | 0.500000 | primary | 338230 1 | /tmp | 11003 | 2 | 0.500000 | standby | 163939 (2 rows) - Parser enhancements for query rewriting (Yugo Nagata) INSERT/UPDATE/DELETE with WITH clause, writable CTE, RETURNING clause can now be properly handled in query rewriting in native replication mode. - Allow to open pool_passwd file in read only mode by pgpool-II main process (Tatsuo Ishii) - Allow to run pgpool in debug mode in regression tests (Tatsuo Ishii) - doc:Add pgpool_adm documents (Tatsuo Ishii) - doc:Update Chinese documents (Bambo Huang) __________________________________________________________________ * Bug fixes (since 3.4.3) - doc: Fix misinformation regarding load balancing in docs (Tatsuo Ishii) In streaming replication mode, DECLARE, FETCH, CLOSE and SHOW are sent to primary node only. Pointed out in [pgpool-general-jp: 1378]. - Issue fsync() when writing pgpool_status. (Tatsuo Ishii) This ensures that pgpool_status is saved to permanent storage and allow to survive after system crash. - Fix reset query stuck problem (Muhammad Usama) It is reported that reset query (DISCARD ALL etc.) occasionally does not finish and pgpool child remain waiting for reply from the backend thus client cannot connect to pgpool (for example bug report #107). The cause of problem is not identified yet but if client suddenly closes connection to pgpool in the middle of query processing, backend may not accept the reset queries because they are not ready for query. The fix is to keep track of the status of frontend socket state and not caching the PostgreSQL connection if the connection to frontend was not properly terminated. - test: Fix false alarm of regression tset 062 (Yugo Nagata) - test: Fix broken regression test for native replication (Yugo Nagata) Test for insert-lock didn't work. - test: Fix regress test to sleep after pgpool_reload (Yugo Nagata) Some regression tests modify configuration file and reloads. However, sometimes these were not applied to pgpool just after reloading. - Fix inconsistency of sequence values in replication mode (Yugo Nagata) When a schema name was provided, the table name was quoted wrongly as like "public.mytbl" instead of "public"."mytbl". So, pool_regclass and to_regclass couldn't find right table oid and insert lock was never executed. This caused inconsistency between DB nodes. - test: Fix complication error and segfault of timestamp rewrite test (Yugo Nagata) - doc: Fix untranslated sentence in Japanese document (Yugo Nagata) - Fix ancient bug of pool_push() and friends. (Tatsuo Ishii) It allocates buffer using realloc and uses the pointer returned. However it does the pointer calculation *before* realloc gets called. So the calculation uses the old pointer value, which causes various problems including segfault later. Also there were other problems with it. The buffer pointer and buffer size variable is not initialized. The buffer is not freed by pool_close. Typo in debugging message (3.4 or later only). They are fixed as well. - doc: Fix wrong description in documents about log_standby_delay (Yugo Nagata) - Fix segfault that occurs when function is used in FROM clause (Yugo Nagata) PREPARE statements in streaming-reapplication mode and INSERT/UPDATE with SELECT in native-replication mode were affected. For example: - prepare p as select * from generate_series(1,1); - insert into tbl select now(), * from generate_series(1,1); - doc: Add caution about JDBC driver version regarding app_name_redirect_preference_list (Tatsuo Ishii) - Fix hang problem reported in bug #145. (Tatsuo Ishii) The problem occurs when all the condition below are met: 1) pgpool-II 3.4 or later 2) streaming replication mode 3) primary node is also load balance node 4) extended protocol is used 5) client_idle_limit reached - Fix a in-memory query cache bug (Tatsuo Ishii) If extended query protocol is used and a bind/execute message arrives which uses a statement created by prior parse message, the temp_cache is not initialized by a parse messages. Thus messages are added to pre existing temp cache buffer which causes the trouble, that is, when the cached result returns, Data Row message and Command Complete message appeared twice. Per by bug #152. - test: Fix regression test 065. (Tatsuo Ishii) The path to JDBC driver was explicitly defined. This is wrong. This should be inherited from JDBC_DRIVER environment variable. - test: Fix possible hang-up of regression test 054.postgres_fdw (Yugo Nagata) - test: Add option to regress.sh and pgpool_setup for unix domain socket directory (Yugo Nagata) - doc: Add missing descriptions about default values to documents (Yugo Nagata) - test: Fix regression test 055 for rhel7 rpm (Yugo Nagata) - Fix reset query stuck problem (Muhammad Usama) The issue is already fixed in older branches and this fix adopts the same solution used by 3.3 series, i.e. closing the backend connection when client idle limit is reached. - Fix bug with "SET TRANSACTION READ ONLY" (Tatsuo Ishii) Pgpool-II remembers that non read only queries (including SET) were executed in an explicit transaction and adds a "writing transaction" mark to the transaction. The mark affects the query routing behavior of pgpool-II while running in streaming replication mode. Pgpool-II starts sending queries to the primary after the mark is set. Because the effect of writing queries may appear on standbys after some delay in streaming replication mode, it is safer to route read queries to the primary after the mark is set. However there's oversight here. "SET TRANSACTION READ ONLY" does no data modification and should be treated as an exception. Per bug #157. - test: Fix to use timeout command to handle time out of regress test 062 (Yugo Nagata) - Fix to show wrong error (Tatsuo Ishii) connect_with_timeout() does not show proper error info when getsockopt(SO_ERROR) reports an error. Pointed out in bug #159. - test: Add regress.sh missing \n in help messages (Yugo Nagata) - Fix the logic issue in get_backends_status() function (Muhammad Usama) get_backends_status () function counts the number of current valid and down backend nodes. The function assumed that the node was also invalid when its connection status was down. However, that is not always right. - Fix white/black_memqcache_table_list not to require quotation (Yugo Nagata) The tables and schemas name specified in *_memqcache_table_list were needed to be quoted by double quotation. Patch contributed by Dang Minh Huong. Per [pgpool-hackers: 1323] - Fix FATAL error with reloading (Tatsuo Ishii) While reloading pgpool.conf, the number of DB nodes is tentatively set to 0, then counted up until reaching to the actual number of backends by the pgpool main process. Unfortunately the variable was on the shared memory and it confused pgpool child process when they were using the variable and this caused FATAL error. Per bug #156 report by harukat. - test: Add some tests for white/black_memqcache_table_list to regression test 006.memqcache (Yugo Nagata) - Fix reset query stuck problem (Muhammad Usama, Tatsuo Ishii) When pool_read fails to read from frontend or pool_flush fails to write to the frontend, report FRONTEND_ERROR, rather than ERROR to disconnect and terminate pgpool child process, to prevent the query stuck problem. - test: Fix some regression tests that failed in debug mode (Yugo Nagata) - Fix performance degradation while using IPv6 (Muhammad Usama) Per bug #165. =============================================================================== 3.4 Series (2014/11/07 - ) =============================================================================== 3.4.8 (tataraboshi) 2016/08/31 * Version 3.4.8 This is a bugfix release against pgpool-II 3.4.7. __________________________________________________________________ * Bug fixes - Fix buffer over run problem in "show pool_nodes". (Tatsuo Ishii) While processing "show pool_nodes", the buffer for hostname was too short. It should be same size as the buffer used for pgpool.conf. Problem reported by a twitter user who is using pgpool on AWS (which could have very long hostname). - Fix usage of wait(2) in pgpool main process. (Tatsuo Ishii) The usage of wait(2) in pgpool main could cause infinite wait in the system call. Solution is, to use waitpid(2) instead of wait(2). - Save and restore errno in each signal handler. (Tatsuo Ishii) - Fix handling of pcp_listen_addresses config parameter. (Muhammad Usama) - Fix "kind mismatch" error message in pgpool. (Muhammad Usama) Many of "kind mismatch..." errors are caused by notice/warning messages produced by one or more of the DB nodes. In this case now Pgpool-II forwards the messages to frontend, rather than throwing the "kind mismatch..." error. This would reduce the chance of "kind mismatch..." errors. See [pgpool-hackers: 1501] for more details. - Replace "MAJOR" macro to prevent occasional failure. (Tatsuo Ishii) The macro calls pool_virtual_master_db_node_id() and then access backend->slots[id]->con using the node id returned. In rare cases, it could point to 0 (in case when the DB node is not connected), which gives access to con->major, then it causes a segfault. See bug 225 for related info. - doc : Fixing a typo in english doc (Muhammad Usama) - doc : fix Japanese document typo. (Bo Peng) - Fixing a typo in the log message. (Muhammad Usama) - Tighten up health check timer expired condition in pool_check_fd(). (Muhammad Usama) - doc : Add comment to the document about connection_cache. (Tatsuo Ishii) - Fix for 237 that Pgpool-II fails to start if listen_addresses is empty string. (Muhammad Usama) The socket descriptor array (fds[]) was not getting the array end marker when TCP listen addresses are not used. See bug 237 for related info. =============================================================================== 3.4.7 (tataraboshi) 2016/06/17 * Version 3.4.7 This is a bugfix release against pgpool-II 3.4.6. __________________________________________________________________ * New features - Allow to access to pgpool while doing health checking (Tatsuo Ishii) Currently any attempt to connect to pgpool fails if pgpool is doing health check against failed node even if fail_over_on_backend_error is off because pgpool child first tries to connect to all backend including the failed one and exits if it fails to connect to a backend (of course it fails). This is a temporary situation and will be resolved before pgpool executes failover. However if the health check is retrying, the temporary situation keeps longer depending on the setting of health_check_max_retries and health_check_retry_delay. This is not good. Attached patch tries to mitigate the problem: - When an attempt to connect to backend fails, give up connecting to the failed node and skip to other node, rather than exiting the process if operating in streaming replication mode and the node is not primary node. - Mark the local status of the failed node to "down". - This will let the primary node be selected as a load balance node and every queries will be sent to the primary node. If there's other healthy standby nodes, one of them will be chosen as the load balance node. - After the session is over, the child process will suicide to not retain the local status. Per [pgpool-hackers: 1531]. * Bug fixes - Fix is_set_transaction_serializable() when SET default_transaction_isolation TO 'serializable'. (Bo Peng) SET default_transaction_isolation TO 'serializable' is sent to not only primary but also to standby server in streaming replication mode, and this causes an error. Fix is, in streaming replication mode, SET default_transaction_isolation TO 'serializable' is sent only to the primary server. See bug 191 for related info. - Fix Chinese documentation bug about raw mode (Yugo Nagata, Bo Peng) Connection pool is available in raw mode. - Fix confusing comments in pgpool.conf (Tatsuo Ishii) - Permit pgpool to support multiple SSL cipher protocols (Muhammad Usama) Currently TLSv1_method() is used to initialize the SSL context, that puts an unnecessary limitation to allow only TLSv1 protocol for SSL communication. While postgreSQL supports other ciphers protocols as well. The commit changes the above and initializes the SSLSession using the SSLv23_method() (same is also used by PostgreSQL). Because it can negotiate the use of the highest mutually supported protocol version and remove the limitation of one specific protocol version. - If statement timeout is enabled on backend and do_query() sends a (Tatsuo Ishii) query to primary node, and all of following user queries are sent to standby, it is possible that the next command, for example END, could cause a statement timeout error on the primary, and a kind mismatch error on pgpool-II is raised. This fix tries to mitigate the problem by sending sync message instead of flush message in do_query(), expecting that the sync message reset the statement timeout timer if we are in an explicit transaction. We cannot use this technique for implicit transaction case, because the sync message removes the unnamed portal if there's any. Plus, pg_stat_statement will no longer show the query issued by do_query() as "running". See bug 194 for related info. - Fix a possible hang during health checking (Yugo Nagata) Health checking was hang when any data wasn't sent from backend after connect(2) succeeded. To fix this, pool_check_fd() returns 1 when select(2) exits with EINTR due to SIGALRM while health checking is performed. Reported and patch provided by harukat and some modification by Yugo. See bug 204 for related info. - change the Makefile under this directory src/sql/,that is proposed by (Bo Peng) [pgpool-hackers: 1611] - Fix bug with load balance node id info on shmem (Tatsuo Ishii) There are few places where the load balance node was mistakenly put on wrong place. It should be placed on: ConnectionInfo *con_info[child id, connection pool_id, backend id].load_balancing_node]. In fact it was placed on: *con_info[child id, connection pool_id, 0].load_balancing_node]. As long as the backend id in question is 0, it is ok. However while testing pgpool-II 3.6's enhancement regarding failover, if primary node is 1 (which is the load balance node) and standby is 0, a client connecting to node 1 is disconnected when failover happens on node 0. This is unexpected and the bug was revealed. It seems the bug was there since long time ago but it had not found until today by the reason above. - Deal with the case when the primary is not node 0 in streaming replication mode. (Tatsuo Ishii) http://www.pgpool.net/mantisbt/view.php?id=194#c837 reported that if primary is not node 0, then statement timeout could occur even after bug194-3.3.diff was applied. After some investigation, it appeared that MASTER macro could return other than primary or load balance node, which was not supposed to happen, thus do_query() sends queries to wrong node (this is not clear from the report but I confirmed it in my investigation). pool_virtual_master_db_node_id(), which is called in MASTER macro returns query_context->virtual_master_node_id if query context exists. This could return wrong node if the variable has not been set yet. To fix this, the function is modified: if the variable is not either load balance node or primary node, the primary node id is returned. =============================================================================== 3.4.6 (tataraboshi) 2016/04/26 * Version 3.4.6 This is a bugfix release against pgpool-II 3.4.5. __________________________________________________________________ * Bug fixes - Fix for segfault during trusted_servers check (Muhammad Usama) PostgreSQL's memory and exception manager APIs adopted by the pgpool 3.4 are not thread safe and are causing the segmentation fault in the watchdog lifecheck process, as it uses the threads to ping configured trusted hosts for checking the upstream connections. Fix is to remove threads and use the child process approach instead. See [pgpool-general: 4569] for more details. - Removing the limit on the maximum number of items in the black_function_list and white_function_list lists. (Muhammad Usama) extract_string_tokens in pool_config uses the fixed size malloc on the array to hold the black_function_list/white_function_list items. This imposes a limit of maximum items in these lists. The fix is to use realloc to increase the array size when it gets full. - Redirect all user queries to primary server (Tatsuo Ishii) Up to now some user queries are sent to other than the primary server even if load_balance_mode = off. This commit changes the behavior: if load_balance_mode = off in streaming replication mode, now all the user queries are sent to the primary server only. Per bug #189. - Change the PID length of pcp_proc_count command result to 6 characters long (Bo Peng) If the pgpool process ID are over 5 characters, the 6th character of each process ID will be removed. This commit changes the process ID length of pcp_proc_count command result to 6 characters long. Per bug #188. =============================================================================== 3.4.5 (tataraboshi) 2016/04/04 * Version 3.4.5 This is a bugfix release against pgpool-II 3.4.4. __________________________________________________________________ * Bug fixes - test: Fix test/regression/clean.sh to remove binary files of 010.rewrite_timestamp test (Yugo Nagata) - Fix memory leak reported by Coverity (CID 1350095) (Yugo Nagata) - Fixing pgpool-recovery module compilation issue with PostgreSQL 9.6 (Muhammad Usama) Incorporating the change of function signature for GetConfigOption..() functions in PostgreSQL 9.6. - Fix a reset query stuck problem (Muhammad Usama) The solution is to report FRONTEND_ERROR instead of simple ERROR when pool_flush on front-end socket fails.

To fix this, pgpool_setup now generates startall script in which pgpool sends stdout/stderr to cat command by pipe, and cat writes to the log file. - Fix to validate the PCP packet length (Muhammad Usama) Without the validation check, a malformed PCP packet can crash the PCP child and/or can run the server out of memory by sending the packet with a very large data size. =============================================================================== 3.4.4 (tataraboshi) 2016/02/05 * Version 3.4.4 This is a bugfix release against pgpool-II 3.4.3. __________________________________________________________________ * Bug fixes - doc: Fix misinformation regarding load balancing in docs (Tatsuo Ishii) In streaming replication mode, DECLARE, FETCH, CLOSE and SHOW are sent to primary node only. Pointed out in [pgpool-general-jp: 1378]. - Issue fsync() when writing pgpool_status (Tatsuo Ishii) This ensures that pgpool_status is saved to permanent storage and allow to survive after system crash. - Fix reset query stuck problem (Muhammad Usama) It is reported that reset query (DISCARD ALL etc.) occasionally does not finish and pgpool child remain waiting for reply from the backend thus client cannot connect to pgpool (for example bug report #107). The cause of problem is not identified yet but if client suddenly closes connection to pgpool in the middle of query processing, backend may not accept the reset queries because they are not ready for query. The fix is to keep track of the status of frontend socket state and not caching the PostgreSQL connection if the connection to frontend was not properly terminated. - test: Fix false alarm of regression tset 062 (Yugo Nagata) - test: Fix broken regression test for native replication (Yugo Nagata) Test for insert lock didn't work. - test: Fix regress test to sleep after pgpool_reload (Yugo Nagata) Some regression tests modify configuration file and reloads. However, sometimes these were not applied to pgpool just after reloading. - Fix inconsistency of sequence values in replication mode (Yugo Nagata) When a schema name was provided, the table name was quoted wrongly as like "public.mytbl" instead of "public"."mytbl". So, pool_regclass and to_regclass couldn't find right table oid and insert lock was never executed. This caused inconsistency between DB nodes. - test: Fix complication error and segfault of timestamp rewrite test (Yugo Nagata) - test: Add timestamp-rewrite unit test to regression test suite (Yugo Nagata) - doc: Fix untranslated sentence in Japanese document (Yugo Nagata) - Fix ancient bug of pool_push() and friends (Tatsuo Ishii) It allocates buffer using realloc and uses the pointer returned. However it does the pointer calculation *before* realloc gets called. So the calculation uses the old pointer value, which causes various problems including segfault later. Also there were other problems with it. The buffer pointer and buffer size variable is not initialized. The buffer is not freed by pool_close. Typo in debugging message (3.4 or later only). They are fixed as well. - doc: Fix wrong description about log_standby_delay in the document (Yugo Nagata) - doc: Add caution about JDBC driver version regarding app_name_redirect_preference_list (Tatsuo Ishii) - Fix hang problem reported in bug#145 (Tatsuo Ishii) The problem occurs when all the condition below are met: 1) pgpool-II 3.4 or later 2) streaming replication mode 3) primary node is also load balance node 4) extended protocol is used 5) client_idle_limit reached - test: Fix regression test 065 (Tatsuo Ishii) The path to JDBC driver was explicitly defined. This is wrong. This should be inherited from JDBC_DRIVER environment variable. - test: Fix possible hang-up of regression test 054.postgres_fdw (Yugo Nagata) - test: Add option to regress.sh and pgpool_setup for unix domain socket directory (Yugo Nagata) - doc: Add missing descriptions about default values to documents (Yugo Nagata) - test: Fix a bug of regress.sh option handling (Yugo Nagata) - test: Fix regression test 055.backend_all_down to use PGSOCKET_DIR for PostgreSQL rhel7 rpm (Yugo Nagata) - Fix reset query stuck problem (Muhammad Usama) The issue is already fixed in older branches and this fix adopts the same solution used by 3.3 series, i.e. closing the backend connection when client idle limit is reached. - Fix bug with "SET TRANSACTION READ ONLY" (Tatsuo Ishii) Pgpool-II remembers that non read only queries (including SET) were executed in an explicit transaction and adds a "writing transaction" mark to the transaction. The mark affects the query routing behavior of pgpool-II while running in streaming replication mode. Pgpool-II starts sending queries to the primary after the mark is set. Because the effect of writing queries may appear on standbys after some delay in streaming replication mode, it is safer to route read queries to the primary after the mark is set. However there's oversight here. "SET TRANSACTION READ ONLY" does no data modification and should be treated as an exception. Per bug #157. - test: Fix to use timeout command to handle time out of regress test 062 (Yugo Nagata) - Fix to show wrong error (Tatsuo Ishii) connect_with_timeout() does not show proper error info when getsockopt(SO_ERROR) reports an error. Pointed out in bug #159. - test: Add missing \n in help messages (Yugo Nagata) - Fixing the logic issue in get_backends_status() function (Muhammad Usama) get_backends_status () function counts the number of current valid and down backend nodes. The function assumed that the node was also invalid when its connection status was down. However, that is not always right. - test: Fix regression test 003.failover for rhel7 postgresql rpm (Yugo Nagata) The expected result of 'show pool_nodes' is fixed to use PGSOCKET_DIR in hostname column. - Fix white/black_memqcache_table_list not require quotation (Yugo Nagata) The tables and schemas name specified in *_memqcache_table_list were needed to be quoted by double quotation. Patch contributed by Dang Minh Huong. Per [pgpool-hackers: 1323] - Fix FATAL error with reloading (Tatsuo Ishii) While reloading pgpool.conf, the number of DB nodes is tentatively set to 0, then counted up until reaching to the actual number of backends by the pgpool main process. Unfortunately the variable was on the shared memory and it confused pgpool child process when they were using the variable and this caused FATAL error. Per bug #156 report by harukat. - test: Add some tests for white/black_memqcache_table_list to regression test 006.memqcache (Yugo Nagata) - Fix reset query stuck problem (Muhammad Usama, Tatsuo Ishii) When pool_read fails to read from frontend or pool_flush fails to write to the frontend, report FRONTEND_ERROR, rather than ERROR to disconnect and terminate pgpool child process, to prevent the query stuck problem. - test: Fix regression test 008 & 009 failure in debug mode (Yugo Nagata) - Fix performance degradation while using IPv6 (Muhammad Usama) Per bug #165. - Add some warning messages for wd_authkey hash calculation failure (Yugo Nagata) Sometimes wd_authkey calculation fails for some reason other than authkey mismatch. The additional messages make these distinguishable for each other. - test: Fix regression test to check timeout of each test (Yugo Nagata) - test: Allow timeout value to be specified by the command option (Yugo Nagata) - Fix bugs with data modifying WITH clause. (Tatsuo Ishii) pgpool-II did not recognize the data modifying WITH clause despite pgpool-II 3.3 or after has SQL parser which recognizes it. The bug has been fixed in pgpool-II 3.5 (having PostgreSQL 9.5 parser), and the fix is back ported to pgpool-II 3.3 and 3.4. Per bug #153. - Fix segfault that occurs when function is used in FROM clause (Yugo Nagata) PREPARE statements in streaming-reapplication mode and INSERT/UPDATE with SELECT in native-replication mode were affected. For example: - prepare p as select * from generate_series(1,1); - insert into tbl select now(), * from generate_series(1,1); - Fix broken arping_cmd configuration check(Muhammad Usama) wd_chk_setuid() function was bailing out with the NOTICE message as soon as it finds the setuid bit is not set on any configured network command and was ignoring the rest of configurations. Per bug #139. - doc: Add restriction about starting multiple pgpool simultaneously (Yugo Nagata) - Fix to use saved errno for erreport instead of the direct value (Yugo Nagata) Some system calls are called in errmsg() and errhint(), and it isn't safe to pass errno directly as an argument. This caused the confusable log message as below. DETAIL: connect() reports failure "Success" - Fix a in-memory query cache bug (Tatsuo Ishii) If extended query protocol is used and a bind/execute message arrives which uses a statement created by prior parse message, the temp_cache is not initialized by a parse messages. Thus messages are added to pre existing temp cache buffer which causes the trouble, that is, when the cached result returns, Data Row message and Command Complete message appeared twice. Per by bug #152. - Fix a compile issue on freebsd, added missing include files (Muhammad Usama) =============================================================================== 3.4.3 (tataraboshi) 2015/07/24 * Version 3.4.3 This is a bugfix release against pgpool-II 3.4.2. __________________________________________________________________ * Bug fixes - Fix "cannot find xlog functions" error in pgpool-recovery (Muhammad Usama) The argument data type of PostgreSQL's pg_xlogfile_name() function has been changed from text to pg_lsn since PostgreSQL 9.4. And pgpool-recovery was still trying to locate the function by old signature. - Fix problem with memory cache invalidation (Muhammad Usama) The internal buffer for storing the table oids needs to be homed in long living memory context as it has to survive throughout the child life. See [pgpool-general: 3643] for details. - Pass empty string parameters in failover command when pgpool-II does not have a value for any particular parameter (Muhammad Usama) Instead of omitting the values for the parameters when pgpool-II does not have any value for a particular parameter, it now passes an empty string to the failover command. This makes sure that failover script will always receive the exact number of expected parameters. - pgpool-II should use the local definition of snprintf functions only if they are not provided by OS (Muhammad Usama) - Add debug info to show how much shared memory is allocated (Tatsuo Ishii) - Downgrading the error level for EOF on backend connection for main process (Muhammad Usama) Throwing the FATAL error when EOF is encountered with backend is very harsh in pgpool main process and can cause undesirable behavior. Downgrading it to simple ERROR. - doc: Clarify load balancing condition (Tatsuo Ishii) - doc: Clarify description of pcp_promote_node (Tatsuo Ishii) It does not actually promote PostgreSQL standby. - doc: Fix outdated limitation description about load balancing using JDBC driver (Tatsuo Ishii) Even if autocommit is false, load balancing is possible in certain conditions. - Fix a misplaced code which makes a log code unreachable and rephrase the log message (Muhammad Usama) - Fix a problem in elog.c when forwarding a message to frontend clients (Muhammad Usama) Error while forwarding the message to the frontend client can potentially cause the infinite recursion and terminate the child with ERRORDATA_STACK_SIZE exceeded error. Fix is to check the recursion depth of send_message_to_frontend() function and pulling the plug if it is more than two levels deep. - Fix "select() system call interrupted" error (Tatsuo Ishii) The health check process complains above and then: ERROR: failed to make persistent db connection DETAIL: connection to host:"x.x.x.x:5432 failed However, the healthcheck triggers neither fail over nor retrying. So, except the annoying messages above, everything goes well. This could occur more easily if 1) num_init_children is big and 2) pgpool children go into idle state (no query arrived from client for child_life_time seconds). Original bug report is [pgpool-general: 3756] Connection Interrupted. Patch created by Tatsuo Ishii. Enhancement from Usama. - Fix the case when user table includes spaces (Tatsuo Ishii) For example if table names including spaces are used, pgpool-II cannot be handled correctly by the internal functions which access system catalogs and it results in SQL errors. Solution is, to always use delimited identifier. Per bug #136. http://www.pgpool.net/mantisbt/view.php?id=136 Also see [pgpool-general: 3818]. - Allow to use in-memory query cache size more than 4GB (Tatsuo Ishii) This should have been allowed since in memory query cache was born. - Do not send a query for checking insert lock in non replication mode with extended query (Tatsuo Ishii) - Save pgpool_status to disk each time when it is changed (Tatsuo Ishii) Previously, pgpool-II saves pgpool_status file when pgpool-II explicitly is going shutdown. This is fine in most cases and it saves slight CPU cycles. But if pgpool-II killed abnormally or the system forces pgpool-II to go down by OOM killer, next pgpool-II restarting could load obsolete status file. =============================================================================== 3.4.3 (tataraboshi) 2015/07/24 * Version 3.4.3 This is a bugfix release against pgpool-II 3.4.2. __________________________________________________________________ * Bug fixes - Fix "cannot find xlog functions" error in pgpool-recovery (Muhammad Usama) The argument data type of PostgreSQL's pg_xlogfile_name() function has been changed from text to pg_lsn since PostgreSQL 9.4.

Fixed by adding on_exit_reset() at child start-up in both processes. - Fix to use void * type for receiving return value of thread function (Yugo Nagata) Previously int type was used and this could occur stack buffer overflow. This caused an infinity loop of ping error at bringing up or down VIP. - Fix to set SIGCHLD to SIG_DFL instead of SIG_IGN in watchdog processes (Yugo Nagata) When using waitpid, it isn't necessary to set SIGCHLD to SIG_IGN. Rather, it is harmful, and due to this it was regarded that ping command exited abnormally in error even when this succeeded. - Fix to use waitpid instead of wait in exec_ifconfig (Yugo Nagata) - Remove an unnecessary include directive (Yugo Nagata) - Enlarge POOLCONFIG_MAXDESCLEN to 80 (Tatsuo Ishii) This is used in show pool_status command and limits the length of parameter description. Unfortunately recovery_timeout description is 64 chars, which is 1 byte longer than former definition of the macro. - doc: Update document of condition for load balancing (Yugo Nagata) Load balancing is possible in an explicit transaction block even in replication mode since 3.3.0. - Support SSL certificate chains in the certificate file for incoming frontend connections (Muhammad Usama) - Use to_regclass if available in time stamp rewriting in replication mode (Tatsuo Ishii) - Fix to not emits a fatal error message when clear text password auth is used (Muhammad Usama) The problem was introduced in pgpool-II after inclusion of exception manager. EOF on the frontend connection during client authentication should not be treated as an error when the password authentication method is used. psql disconnects from the server in such case to get the password from the terminal, reconnects and sends the read password to server. - previous session for the same child had exited because of some ERROR. (Muhammad Usama) - Fix a hang when an error occurs in a transaction block with replication mode (Yugo Nagata) When an error occurs at a backend node in a transaction block with replication mode, pgpool-II sends an invalid query to other backends to sync transaction states. However, previously, this was not sent to master node, and pgpool-II was waiting for master's response forever. - Fix a problem with pcp_detach_node about graceful node detach (Muhammad Usama) When graceful node detach is requested gracefully, pcp_detach_node should check if it is allowed to process detach_node command on the particular node before blocking the incoming connections and closing the existing connections. - doc: Update table and flowchart of where a query should be sent to (Yugo Nagata) - rpm: pgpool.spec is required only in RHEL/CentOS 7 (Nozomi Anzai) - Fix a compilation issue about sighandler_t type on BSD variants (Muhammad Usama) =============================================================================== 3.4.1 (tataraboshi) 2015/02/05 * Version 3.4.1 This is a bugfix release against pgpool-II 3.4.0. __________________________________________________________________ * Bug fixes - RPM: Add to support for memcached. (Tatsuo Ishii) - Fix number of parameters of pgpool_recovery from 3 to 4. (Tatsuo Ishii) This really should be done before releasing 3.4.0. - test: Allow pgpool_setup to set configuration file directory by setting environment variable PGPOOLDIR (Tatsuo Ishii) - RPM: Rename RPM file (Yugo Nagata) Rename filename to include the RHEL version number like PostgreSQL's official RPM file. (e.g. pgpool-II-pg93-3.4.0-2pgdg.rhel6.x86_64.rpm) - Fix node id range check bug in trigger_failover_command(). (Tatsuo Ishii) The node id should be lower than NUM_BACKENDS. Probably harmless since callers never pass node ids greater or equal to NUM_BACKENDS. - Fix occasional stuck that occurs when a NOTIFY message is sent from a backend. (Muhammad Usama) The issue happens in master slave mode with load balancing when the client is doing extended query messaging. per bug #116 http://www.pgpool.net/mantisbt/view.php?id=116 - test: Fix failover script of pgpool_setup to use absolute path to the database cluster (Tatsuo Ishii) - test: Reorganize port numbers assigned in pgpool_setup (Tatsuo Ishii) Assign base port (11000 by default) to pgpool, base port + 1 to pcp, port + 2 to PostgreSQL node0, port + 3 to PostgreSQL node1 and so on. - Fix a bug that pgpool-II 3.4 can't cancel query (Muhammad Usama) - test: Add regression test for cancelling query (Muhammad Usama) - Fix to not use non-thread-safe APIs in thread functions (Muhammad Usama) pgpool-II has borrowed the Memory and Exception managers from PostgreSQL which never utilizes the threads so its APIs are not thread safe. Previously, those API functions which manipulate the global variables in thread functions, and it caused to undefined behavior or a segmentation fault. Especially, the main process could die silently. - test: Add memory leak regression test (Tatsuo Ishii) - Fix a memory leak with long-lived connections (Muhammad Usama) Problem reported in [pgpool-general: 3325]. - Change the log level of "Frontend Terminated" message to DEBUG1 from LOG (Muhammad Usama) - Fix ill signal behavior of SIGCHLD in exec_ifconfig() (Tatsuo Ishii) For some reason SIGCHLD was set to SIG_IGN *and* tries to wait child process which always fails because SIGCHLD is never delivered. Due to this "ifconfig up" fails when switching to watchdog master. See "[pgpool-general: 3310] for more details. - Allow $_IP_$ having address prefix in if_up_cmd and if_down_cmd (Muhammad Usama) Previously, it is assumed that "$_IP_$" keyword will always have a white space at the end, and when "$_IP_$" has address prefix (e.g. $_IP_$/24), this prefix was ignored. Per bug #122. http://www.pgpool.net/mantisbt/view.php?id=122 - Fix to not send signal to init process (Muhammad Usama) This is more of a guard against a situation where a crash of the pgpool main process can make the child processes to send the signal to system's init process. Per bug #119. http://www.pgpool.net/mantisbt/view.php?id=119 - RPM: Fix "error: Installed (but unpackaged) file(s) found" while creating RPMs for PostgreSQL 9.4 (Tatsuo Ishii) - Allow "show pool_nodes" to print node ids having more than one digits (Muhammad Usama) Problem reported in [pgpool-general: 3374]. - Prevent "WARNING: failed to execute regex matching, pattern is NULL" message that could happen when application name is not set in the old clients (Tatsuo Ishii) - Fix pgpool main process to shutdown in case of child process start-up failures (Muhammad Usama) Problem reported in [pgpool-general: 3358]. - Fix a segmentation fault that could happen in child process error (Muhammad Usama) Problem reported in [pgpool-general: 3377]. - Fix occasional failure in regression test '004.watchdog' (Yugo Nagata) The patch provided by uehara in bug #127. http://www.pgpool.net/mantisbt/view.php?id=127 - Fix client connection leak (Tatsuo Ishii) Since 3.4.0 pgpool-II child does not close the connection to client when it ends the session. This leads to serious "CLOSE_WAIT" flood, which makes pgpool-II unusable since no new connection from clients accepted. Problem reported by Pablo Sanchez in [pgpool-general: 3394]. - Restore SIGCHLD handler to its original after executing if_up/down_cmd (Yugo Nagata) Previously SIGCHLD was set to SIGIGN always after if_up/down_cmd. This led to a incorrect error handling of ping or other commands execution, and warning messages were output to log even when the command exited successfully. - RPM: Add pgpool.service for systemd in RHEL/CentOS 7 (Nozomi Anzai) - Fix process termination after several reload with enabled_pool_hba (Muhammad Usama) - Tighten up checking for app_name_redirect_preference_list and database_redirect_preference_list (Tatsuo Ishii) Before empty application name or database name or invalid DB node number were silently accepted. Now they are strictly checked and let raise fatal error when starting up. Problem reported in [pgpool-general-jp: 1337]. - RPM: Change to use systemd if it is available (Nozomi Anzai) - Fix the behavior of "client_min_messages" configuration parameter (Muhammad Usama) This parameter controls the minimum message levels to be sent to the frontend. Previously, regardless of the value of the parameter all the messages with severity less than NOTICE level were not being forwarded to the client. =============================================================================== 3.4.0 (tataraboshi) 2014/11/07 * Version 3.4.0 This is the first version of pgpool-II 3.4 series. That is, a "major version up" from 3.3 series. __________________________________________________________________ * Incompatible changes - Parallel query mode is obsoleted and is removed from pgpool.conf. This is due to the very few users using the mode (and the relatively high cost to maintain it). Actual codes for the mode are still there and users can use the mode if they specify necessary parameters in pgpool.conf. Note, however, the next version of pgpool-II (will be 3.5.0) will actually remove the code. - "print_timestamp" parameter is removed. Instead new "log_line_prefix" should be used. - Recovery script now accepts 4 parameters, rather than 3 (the 4th parameter is the port number of master PostgreSQL). Existing 3-parameter-style recovery scripts can be used if you don't care about information provided by the 4th parameter. __________________________________________________________________ * New features - Allow fine control of load balancing by using application name or database name. For example, if a client has particular application name, read queries can be redirect to master node, rather than to one of slave nodes (Tatsuo Ishii) - Allow to print pgpool-II process names in the log output. New parameter "log_line_prefix", which is the printf-style string that is output at the beginning of each log line (Muhammad Usama) - Allow to control log verbosity like PostgreSQL. For this purpose new parameters "log_error_verbosity", "client_min_messages", "log_min_messages" are added (Muhammad Usama) - Allow to use SQL comments without disturbing load balancing if new parameter "allow_sql_comments" is on. If it's off, previous behavior is kept (Tatsuo Ishii) - Allow to skip unlogged tables checking by using new parameter "check_unlogged_table". This reduces the number of pgpool-II's internal catalog look up queries and enhances performance (Tatsuo Ishii) - Prevent listen backlog overflow by using new parameter "listen_backlog_multiplier" for very busy systems (Tatsuo Ishii) - Prevent connection timeout to backend by using new parameter "connect_timeout". This is useful in unstable networks (Tatsuo Ishii) __________________________________________________________________ * Enhancements - Builtin SQL parser is now compatible with PostgreSQL 9.4 (Muhammad Usama) - Import PostgreSQL's memory manager and exception manager (Muhammad Usama) - Reorganize source code tree (Muhammad Usama) - The status file "pgpool_status" is now a plain ASCII file. This allows to register down PostgreSQL nodes before pgpool-II starts for example (Tatsuo Ishii) - Allow to use IPv6 address for PostgreSQ (Michael Stapelberg) - Allow to use IPv6 bind address for pgpool-II (Michael Stapelberg) - Rename all occurrence of "on memory query cache" to "in memory query cache" because latter is more correct in English (Tatsuo Ishii) - Add 4th parameter "master node port number" to recovery script (Tatsuo Ishii) - Allow to handle more than 3 database nodes in pgpool_setup (Tatsuo Ishii) __________________________________________________________________ * Bug fixes (since 3.3.4) - Fix failover deadlock problem in watchdog (Muhammad Usama). See bug #105 and [pgpool-committers: 2195] for more details. - As per the PostgreSQL specification, calling close on non existing portals is not an error. So on the same footings this commit ignores all such packets and return the 'close complete' message to client with out going to backend (Muhammad Usama) - Fix many issues/bugs found by Coverity (Muhammad Usama, Tatsuo Ishii) =============================================================================== 3.3 Series (2013/07/30 - ) =============================================================================== 3.3.12 (tokakiboshi) 2016/08/31 * Version 3.3.12 This is a bugfix release against pgpool-II 3.3.11. __________________________________________________________________ * Bug fixes - Fix buffer over run problem in "show pool_nodes". (Tatsuo Ishii) While processing "show pool_nodes", the buffer for hostname was too short. It should be same size as the buffer used for pgpool.conf. Problem reported by a twitter user who is using pgpool on AWS (which could have very long hostname). - Fix usage of wait(2) in pgpool main process. (Tatsuo Ishii) The usage of wait(2) in pgpool main could cause infinite wait in the system call. Solution is, to use waitpid(2) instead of wait(2). - Fix "kind mismatch" error message in pgpool. (Muhammad Usama) Many of "kind mismatch..." errors are caused by notice/warning messages produced by one or more of the DB nodes. In this case now Pgpool-II forwards the messages to frontend, rather than throwing the "kind mismatch..." error. This would reduce the chance of "kind mismatch..." errors. See [pgpool-hackers: 1501] for more details. - Replace "MAJOR" macro to prevent occasional failure. (Tatsuo Ishii) The macro calls pool_virtual_master_db_node_id() and then access backend->slots[id]->con using the node id returned. In rare cases, it could point to 0 (in case when the DB node is not connected), which gives access to con->major, then it causes a segfault. See bug 225 for related info. - doc : Fixing a typo in english doc (Muhammad Usama) - doc : fix Japanese document typo. (Bo Peng) - Fixing a typo in the log message. (Muhammad Usama) - doc : Add comment to the document about connection_cache. (Tatsuo Ishii) =============================================================================== 3.3.11 (tokakiboshi) 2016/06/17 * Version 3.3.11 This is a bugfix release against pgpool-II 3.3.10. __________________________________________________________________ * New features - Allow to access to pgpool while doing health checking (Tatsuo Ishii) Currently any attempt to connect to pgpool fails if pgpool is doing health check against failed node even if fail_over_on_backend_error is off because pgpool child first tries to connect to all backend including the failed one and exits if it fails to connect to a backend (of course it fails). This is a temporary situation and will be resolved before pgpool executes failover. However if the health check is retrying, the temporary situation keeps longer depending on the setting of health_check_max_retries and health_check_retry_delay. This is not good. Attached patch tries to mitigate the problem: - When an attempt to connect to backend fails, give up connecting to the failed node and skip to other node, rather than exiting the process if operating in streaming replication mode and the node is not primary node. - Mark the local status of the failed node to "down". - This will let the primary node be selected as a load balance node and every queries will be sent to the primary node. If there's other healthy standby nodes, one of them will be chosen as the load balance node. - After the session is over, the child process will suicide to not retain the local status. Per [pgpool-hackers: 1531]. * Bug fixes - Fix is_set_transaction_serializable() when SET default_transaction_isolation TO 'serializable'. (Bo Peng) SET default_transaction_isolation TO 'serializable' is sent to not only primary but also to standby server in streaming replication mode, and this causes an error. Fix is, in streaming replication mode, SET default_transaction_isolation TO 'serializable' is sent only to the primary server. See bug 191 for related info. - Fix Chinese documentation bug about raw mode (Yugo Nagata, Bo Peng) Connection pool is available in raw mode. - Fix confusing comments in pgpool.conf (Tatsuo Ishii) - Permit pgpool to support multiple SSL cipher protocols (Muhammad Usama) Currently TLSv1_method() is used to initialize the SSL context, that puts an unnecessary limitation to allow only TLSv1 protocol for SSL communication. While postgreSQL supports other ciphers protocols as well. The commit changes the above and initializes the SSLSession using the SSLv23_method() (same is also used by PostgreSQL). Because it can negotiate the use of the highest mutually supported protocol version and remove the limitation of one specific protocol version. - If statement timeout is enabled on backend and do_query() sends a (Tatsuo Ishii) query to primary node, and all of following user queries are sent to standby, it is possible that the next command, for example END, could cause a statement timeout error on the primary, and a kind mismatch error on pgpool-II is raised. This fix tries to mitigate the problem by sending sync message instead of flush message in do_query(), expecting that the sync message reset the statement timeout timer if we are in an explicit transaction. We cannot use this technique for implicit transaction case, because the sync message removes the unnamed portal if there's any. Plus, pg_stat_statement will no longer show the query issued by do_query() as "running". See bug 194 for related info. - Deal with the case when the primary is not node 0 in streaming replication mode. (Tatsuo Ishii) http://www.pgpool.net/mantisbt/view.php?id=194#c837 reported that if primary is not node 0, then statement timeout could occur even after bug194-3.3.diff was applied. After some investigation, it appeared that MASTER macro could return other than primary or load balance node, which was not supposed to happen, thus do_query() sends queries to wrong node (this is not clear from the report but I confirmed it in my investigation). pool_virtual_master_db_node_id(), which is called in MASTER macro returns query_context->virtual_master_node_id if query context exists. This could return wrong node if the variable has not been set yet. To fix this, the function is modified: if the variable is not either load balance node or primary node, the primary node id is returned. - change the Makefile under the directory src/sql/, that is proposed (Bo Peng) by [pgpool-hackers: 1611] - Fix a possible hang during health checking (Yugo Nagata) Health checking was hang when any data wasn't sent from backend after connect(2) succeeded. To fix this, pool_check_fd() returns 1 when select(2) exits with EINTR due to SIGALRM while health checking is performed. Reported and patch provided by harukat and some modification by Yugo. Per bug #204. backported from 3.4 or later; https://git.postgresql.org/gitweb/?p=pgpool2.git;a=commitdiff;h=ed9f2900f1b611f5cfd52e8f758c3616861e60c0 - Fix bug with load balance node id info on shmem (Tatsuo Ishii) There are few places where the load balance node was mistakenly put on wrong place. It should be placed on: ConnectionInfo *con_info[child id, connection pool_id, backend id].load_balancing_node]. In fact it was placed on: *con_info[child id, connection pool_id, 0].load_balancing_node]. As long as the backend id in question is 0, it is ok. However while testing pgpool-II 3.6's enhancement regarding failover, if primary node is 1 (which is the load balance node) and standby is 0, a client connecting to node 1 is disconnected when failover happens on node 0. This is unexpected and the bug was revealed. It seems the bug was there since long time ago but it had not found until today by the reason above. =============================================================================== 3.3.10 (tokakiboshi) 2016/04/26 * Version 3.3.10 This is a bugfix release against pgpool-II 3.3.9. __________________________________________________________________ * Bug fixes - Removing the limit on the maximum number of items in the black_function_list and white_function_list lists. (Muhammad Usama) extract_string_tokens in pool_config uses the fixed size malloc on the array to hold the black_function_list/white_function_list items. This imposes a limit of maximum items in these lists. The fix is to use realloc to increase the array size when it gets full. - Redirect all user queries to primary server (Tatsuo Ishii) Up to now some user queries are sent to other than the primary server even if load_balance_mode = off. This commit changes the behavior: if load_balance_mode = off in streaming replication mode, now all the user queries are sent to the primary server only. Per bug #189. - Change the PID length of pcp_proc_count command result to 6 characters long (Bo Peng) If the pgpool process ID are over 5 characters, the 6th character of each process ID will be removed. This commit changes the process ID length of pcp_proc_count command result to 6 characters long. Per bug #188. =============================================================================== 3.3.9 (tokakiboshi) 2016/04/04 * Version 3.3.9 This is a bugfix release against pgpool-II 3.3.8. __________________________________________________________________ * Bug fixes - test: Fix test/regression/clean.sh to remove binary files of 010.rewrite_timestamp test (Yugo Nagata) - Fix memory leak reported by Coverity (CID 1350095) (Yugo Nagata) - Fixing pgpool-recovery module compilation issue with PostgreSQL 9.6 (Muhammad Usama) Incorporating the change of function signature for GetConfigOption..() functions in PostgreSQL 9.6. - Fix typo in configure (Tatsuo Ishii) Patch provided by Thomas Munro. - doc: Change description of backend_flag (Tatsuo Ishii) It is pointed out that restarting pgpool-II is not necessary. Per [pgpool-general-jp: 1394]. - doc: Fix installation procedure. (Tatsuo Ishii) With PostgreSQL 9.4 or later, installing pgpool_regclass is not needed. - test: Fix pgpool_setup to not confuse log output (Tatsuo Ishii) Before it simply redirects stdout and stderr of pgpool processes to a log file. This could cause the log contents being garbled or even missed because of race condition caused by multiple process being writing concurrently. To fix this, pgpool_setup now generates startall script in which pgpool sends stdout/stderr to cat command by pipe, and cat writes to the log file. - Fix to validate the PCP packet length (Muhammad Usama) Without the validation check, a malformed PCP packet can crash the PCP child and/or can run the server out of memory by sending the packet with a very large data size. - Fix a reset query stuck problem (Muhammad Usama) The solution is to return POOL_END_WITH_FRONTEND_ERROR instead of POOL_END when pool_flush on front-end socket fails. The original report is [pgpool-general: 4265] Pgpool - connection hangs in DISCARD ALL =============================================================================== 3.3.8 (tokakiboshi) 2016/02/05 * Version 3.3.8 This is a bugfix release against pgpool-II 3.3.7. __________________________________________________________________ * Bug fixes - doc: Fix misinformation regarding load balancing in docs (Tatsuo Ishii) In streaming replication mode, DECLARE, FETCH, CLOSE and SHOW are sent to primary node only. Pointed out in [pgpool-general-jp: 1378]. - Issue fsync() when writing pgpool_status (Tatsuo Ishii) This ensures that pgpool_status is saved to permanent storage and allow to survive after system crash. - test: Fix false alarm of regression tset 062 (Yugo Nagata) - test: Fix broken regression test for native replication (Yugo Nagata) Test for insert lock didn't work. - test: Fix regress test to sleep after pgpool_reload (Yugo Nagata) Some regression tests modify configuration file and reloads. However, sometimes these were not applied to pgpool just after reloading. - Fix inconsistency of sequence values in replication mode (Yugo Nagata) When a schema name was provided, the table name was quoted wrongly as like "public.mytbl" instead of "public"."mytbl". So, pool_regclass and to_regclass couldn't find right table oid and insert lock was never executed. This caused inconsistency between DB nodes. - test: Fix complication error and segfault of timestamp rewrite test (Yugo Nagata) - test: Add timestamp-rewrite unit test to regression test suite (Yugo Nagata) - Fix ancient bug of pool_push() and friends (Tatsuo Ishii) It allocates buffer using realloc and uses the pointer returned. However it does the pointer calculation *before* realloc gets called. So the calculation uses the old pointer value, which causes various problems including segfault later. Also there were other problems with it. The buffer pointer and buffer size variable is not initialized. The buffer is not freed by pool_close. Typo in debugging message (3.4 or later only). They are fixed as well. - doc: Fix wrong description about log_standby_delay in the document (Yugo Nagata) - test: Fix regression test 065 (Tatsuo Ishii) The path to JDBC driver was explicitly defined. This is wrong. This should be inherited from JDBC_DRIVER environment variable. - test: Add option to regress.sh and pgpool_setup for unix domain socket directory (Yugo Nagata) - doc: Add missing descriptions about default values to documents (Yugo Nagata) - test: Fix a bug of regress.sh option handling (Yugo Nagata) - test: Fix regression test 055.backend_all_down to use PGSOCKET_DIR for PostgreSQL rhel7 rpm (Yugo Nagata) - Fix bug with "SET TRANSACTION READ ONLY" (Tatsuo Ishii) Pgpool-II remembers that non read only queries (including SET) were executed in an explicit transaction and adds a "writing transaction" mark to the transaction. The mark affects the query routing behavior of pgpool-II while running in streaming replication mode. Pgpool-II starts sending queries to the primary after the mark is set. Because the effect of writing queries may appear on standbys after some delay in streaming replication mode, it is safer to route read queries to the primary after the mark is set. However there's oversight here. "SET TRANSACTION READ ONLY" does no data modification and should be treated as an exception. Per bug #157. - test: Fix to use timeout command to handle time out of regress test 062 (Yugo Nagata) - test: Add missing \n in help messages (Yugo Nagata) - test: Fix regression test 003.failover for rhel7 postgresql rpm (Yugo Nagata) The expected result of 'show pool_nodes' is fixed to use PGSOCKET_DIR in hostname column. - Fix white/black_memqcache_table_list not require quotation (Yugo Nagata) The tables and schemas name specified in *_memqcache_table_list were needed to be quoted by double quotation. Patch contributed by Dang Minh Huong. Per [pgpool-hackers: 1323] - Fix FATAL error with reloading (Tatsuo Ishii) While reloading pgpool.conf, the number of DB nodes is tentatively set to 0, then counted up until reaching to the actual number of backends by the pgpool main process. Unfortunately the variable was on the shared memory and it confused pgpool child process when they were using the variable and this caused FATAL error. Per bug #156 report by harukat. - test: Add some tests for white/black_memqcache_table_list to regression test 006.memqcache (Yugo Nagata) - Add some warning messages for wd_authkey hash calculation failure (Yugo Nagata) Sometimes wd_authkey calculation fails for some reason other than authkey mismatch. The additional messages make these distinguishable for each other. - test: Fix regression test to check timeout of each test (Yugo Nagata) - test: Allow timeout value to be specified by the command option (Yugo Nagata) - Fix bugs with data modifying WITH clause. (Tatsuo Ishii) pgpool-II did not recognize the data modifying WITH clause despite pgpool-II 3.3 or after has SQL parser which recognizes it. The bug has been fixed in pgpool-II 3.5 (having PostgreSQL 9.5 parser), and the fix is back ported to pgpool-II 3.3 and 3.4. Per bug #153. - Fix broken arping_cmd configuration check(Muhammad Usama) wd_chk_setuid() function was bailing out with the NOTICE message as soon as it finds the setuid bit is not set on any configured network command and was ignoring the rest of configurations. Per bug #139. - doc: Add restriction about starting multiple pgpool simultaneously (Yugo Nagata) - Fix a in-memory query cache bug (Tatsuo Ishii) If extended query protocol is used and a bind/execute message arrives which uses a statement created by prior parse message, the temp_cache is not initialized by a parse messages. Thus messages are added to pre existing temp cache buffer which causes the trouble, that is, when the cached result returns, Data Row message and Command Complete message appeared twice. Per by bug #152. - Ignore close statement/portal request if they do not exist (Tatsuo Ishii) In this case just returns a close complete message to client. This is a back port of the following commit from pgpool-II 3.4: 1a37e1c35bd8b6f10f524693bbcb7b51f73b4bf0 - test: Fix port numbers in expected result of show pool_nodes (Yugo Nagata) =============================================================================== 3.3.7 (tokakiboshi) 2015/07/24 * Version 3.3.7 This is a bugfix release against pgpool-II 3.3.6. __________________________________________________________________ * Bug fixes - Fix "cannot find xlog functions" error in pgpool-recovery (Muhammad Usama) The argument data type of PostgreSQL's pg_xlogfile_name() function has been changed from text to pg_lsn since PostgreSQL 9.4. And pgpool-recovery was still trying to locate the function by old signature. - Pass empty string parameters in failover command when pgpool-II does not have a value for any particular parameter (Muhammad Usama) Instead of omitting the values for the parameters when pgpool-II does not have any value for a particular parameter, it now passes an empty string to the failover command. This makes sure that failover script will always receive the exact number of expected parameters. - doc: Clarify load balancing condition (Tatsuo Ishii) - doc: Clarify description of pcp_promote_node (Tatsuo Ishii) It does not actually promote PostgreSQL standby. - doc: Fix outdated limitation description about load balancing using JDBC driver (Tatsuo Ishii) Even if autocommit is false, load balancing is possible in certain conditions. - Fix "select() system call interrupted" error (Tatsuo Ishii) The health check process complains above and then: ERROR: failed to make persistent db connection DETAIL: connection to host:"x.x.x.x:5432 failed However, the healthcheck triggers neither fail over nor retrying. So, except the annoying messages above, everything goes well. This could occur more easily if 1) num_init_children is big and 2) pgpool children go into idle state (no query arrived from client for child_life_time seconds). Original bug report is [pgpool-general: 3756] Connection Interrupted. Patch created by Tatsuo Ishii. Enhancement from Usama. - Fix the case when user table includes spaces (Tatsuo Ishii) For example if table names including spaces are used, pgpool-II cannot be handled correctly by the internal functions which access system catalogs and it results in SQL errors. Solution is, to always use delimited identifier. Per bug #136. http://www.pgpool.net/mantisbt/view.php?id=136 Also see [pgpool-general: 3818]. - Allow to use in-memory query cache size more than 4GB (Tatsuo Ishii) This should have been allowed since in memory query cache was born. - Do not send a query for checking insert lock in non replication mode with extended query (Tatsuo Ishii) =============================================================================== 3.3.6 (tokakiboshi) 2015/04/08 * Version 3.3.6 This is a bugfix release against pgpool-II 3.3.5. __________________________________________________________________ * Bug fixes - rpm: Fix %tmpfiles_create to not be executed in RHEL/CentOS 6 (Nozomi Anzai) - Fix to use void * type for receiving return value of thread function (Yugo Nagata) Previously int type was used and this could occur stack buffer overflow. This caused an infinity loop of ping error at bringing up or down VIP. - Fix to set SIGCHLD to SIG_DFL instead of SIG_IGN in watchdog processes (Yugo Nagata) When using waitpid, it isn't necessary to set SIGCHLD to SIG_IGN. Rather, it is harmful, and due to this it was regarded that ping command exited abnormally in error even when this succeeded. - Remove an unnecessary include directive (Yugo Nagata) - Enlarge POOLCONFIG_MAXDESCLEN to 80 (Tatsuo Ishii) This is used in show pool_status command and limits the length of parameter description. Unfortunately recovery_timeout description is 64 chars, which is 1 byte longer than former definition of the macro. - doc: Update document of condition for load balancing (Yugo Nagata) Load balancing is possible in an explicit transaction block even in replication mode since 3.3.0. - Support SSL certificate chains in the certificate file for incoming frontend connections (Muhammad Usama) - Use to_regclass if available in time stamp rewriting in replication mode (Tatsuo Ishii) - Fix a hang when an error occurs in a transaction block with replication mode (Yugo Nagata) When an error occurs at a backend node in a transaction block with replication mode, pgpool-II sends an invalid query to other backends to sync transaction states. However, previously, this was not sent to master node, and pgpool-II was waiting for master's response forever. - Fix a problem with pcp_detach_node about graceful node detach (Muhammad Usama) When graceful node detach is requested gracefully, pcp_detach_node should check if it is allowed to process detach_node command on the particular node before blocking the incoming connections and closing the existing connections. - doc: Update table and flowchart of where a query should be sent to (Yugo Nagata) - rpm: pgpool.service is required only in RHEL/CentOS 7 (Nozomi Anzai) =============================================================================== 3.3.5 (tokakiboshi) 2015/02/05 * Version 3.3.5 This is a bugfix release against pgpool-II 3.3.4. __________________________________________________________________ * Bug fixes - doc: Describe explicitly that the number of slave nodes is not necessarily 1 (Tatsuo Ishii) - Fix occasional deadlock in failover with watchdog enabled (Muhammad Usama) per bug #105 http://www.pgpool.net/mantisbt/view.php?id=105 - Fix uninitialized variable (Tatsuo Ishii) Per Coverity 1234603. - doc: Fix missing release note entries in the previous release (Tatsuo Ishii) - test: Fix wait_for_pgpool_startup in pgpool_setup to use "postgres" database rather than "test" (Tatsuo Ishii) The test database may or may not exist and if it does not, it will always retry until timeout expired (20 seconds), and regression test takes unnecessary long. - Fix possible segmentation fault in query cache (Tatsuo Ishii) - RPM: Add to support for memcached. (Tatsuo Ishii) - test: Allow pgpool_setup to set configuration file directory by setting environment variable PGPOOLDIR (Tatsuo Ishii) - RPM: Rename RPM file (Yugo Nagata) Rename filename to include the RHEL version number like PostgreSQL's official RPM file. (e.g. pgpool-II-pg93-3.4.0-2pgdg.rhel6.x86_64.rpm) - Fix node id range check bug in trigger_failover_command(). (Tatsuo Ishii) The node id should be lower than NUM_BACKENDS. Probably harmless since callers never pass node ids greater or equal to NUM_BACKENDS. - test: Fix failover script of pgpool_setup to use absolute path to the database cluster (Tatsuo Ishii) - test: Add memory leak regression test (Tatsuo Ishii) - Fix ill signal behavior of SIGCHLD in exec_ifconfig() (Tatsuo Ishii) For some reason SIGCHLD was set to SIG_IGN *and* tries to wait child process which always fails because SIGCHLD is never delivered. Due to this "ifconfig up" fails when switching to watchdog master. See "[pgpool-general: 3310] for more details. - Allow $_IP_$ having address prefix in if_up_cmd and if_down_cmd (Muhammad Usama) Previously, it is assumed that "$_IP_$" keyword will always have a white space at the end, and when "$_IP_$" has address prefix (e.g. $_IP_$/24), this prefix was ignored. Per bug #122. http://www.pgpool.net/mantisbt/view.php?id=122 - Allow "show pool_nodes" to print node ids having more than one digits (Muhammad Usama) Problem reported in [pgpool-general: 3374]. - Fix occasional failure in regression test '004.watchdog' (Yugo Nagata) The patch provided by uehara in bug #127. http://www.pgpool.net/mantisbt/view.php?id=127 - Restore SIGCHLD handler to its original after executing if_up/down_cmd (Yugo Nagata) Previously SIGCHLD was set to SIGIGN always after if_up/down_cmd. This led to a incorrect error handling of ping or other commands execution, and warning messages were output to log even when the command exited successfully. - RPM: Add pgpool.service for systemd in RHEL/CentOS 7 (Nozomi Anzai) - RPM: Split pgpool_regclass and pgpool_recovery as a separate extension package (Tatsuo Ishii) On PostgreSQL server, only the extension package is required, no pgpool full package is necessary. Per Andrew N Golovkov. - RPM: Fix wrong SSL configure option in the RPM spec file (Tatsuo Ishii) SSL enabling option is "--with-openssl=/usr" and this is wrong. This should be "--with-openssl". Per bug #115. http://www.pgpool.net/mantisbt/view.php?id=115 - RPM: Change to use systemd if it is available and adopt to PostgreSQL 9.4 (Nozomi Anzai) - Fix to disable debug mode by reloading config (Yugo Nagata) Per bug #114 http://www.pgpool.net/mantisbt/view.php?id=114 =============================================================================== 3.3.4 (tokakiboshi) 2014/09/05 * Version 3.3.4 This is a bugfix release against pgpool-II 3.3.3. __________________________________________________________________ * Bug fixes - Fix a typo of pgpool.spec (Yugo Nagata) - Fix bug that worker child process keeps failing when there's no primary backend (Tatsuo Ishii) Problem identified and fix contributed by Junegunn Choi. See [pgpool-hackers: 471] for more details. - Close listen socket when smart shutdown request is made (Tatsuo Ishii) When smart shutdown process starts, pgpool children still listen on the port and clients can send further connection requests which fail in the end. Which is not only waste of time, but also prevents a load balancer which sits in front of pgpool from realizing the pgpool is going down. Problem analyzed and patch provided by Junegunn Choi in [pgpool-hackers 474], and enhanced to take care not only inet domain socket but UNIX domain socket by Tatsuo Ishii. - doc: Add cautions that recovery commands are killed by statement_timeout of PostgreSQL. (Tatsuo Ishii) - test: Fix bug that wait_for_pgpool_startup does not work. (Tatsuo Ishii) - test: Fix test driver for watchdog to use wait_for_pgpool_startup correctly (Tatsuo Ishii) - Fix to ignore a harmless error code when executing ifconfig command (Yugo Nagata) When executing command such as ifconfig or ping by execv() in a forked child process, wait() can fails with an error code ECHILD, although the process exists exactly, if SIGCHLD is set to SIG_IGN in Linux. We should ignore this and not treat as failure of the command. - test: Add undocumented "-j" option to the script comment. (Tatsuo Ishii) - test: Fix unwanted JDBC regression test failure (Tatsuo Ishii) - test: Fix to prevent regression test failures on slow machines (Tatsuo Ishii) - test: Allow to specify PostgreSQL library directory by environment variable (Tatsuo Ishii) - Adopt PostgreSQL 9.4 having to_regclass (Tatsuo Ishii) PostgreSQL 9.4 has built-in function "to_regclass", which has equivalent functionality of pgpool_regclass. Now pgpool searches to_regclass first then try pgpool_regclass. - Fix unportable code related to SO_REUSEPORT (Tatsuo Ishii) There are several places using setsockopt(sock, SOL_SOCKET, SO_REUSEPORT...). SO_REUSEPORT is not available on all Linux kernels and the source code uses ifdef to detect the feature in the compile time. Problem is, the binary created with kernel which provides the feature cannot run on a kernel which does not provide the feature. Fix is, detecting the feature in the run time by checking error code returned by setsockopt() and ignore it if the cause of the error is lacking the feature. - doc: Remove old restriction description which is no longer true (Tatsuo Ishii) - Fix return type of text_to_lsn() function (Yugo Nagata) This caused compile warning. - Fix file descriptor leak when daemonize. (Tatsuo Ishii) Per Coverity 1111471. - Fix memory leak. (Tatsuo Ishii) Per Coverity 1111442. - Fix pgpool.init's long-standing bug of stop/restart failure (Yugo Nagata) In previous, pgpool.init uses killproc for stopping pgpool, but there are several problems. In the new version, "pgpool -m fast stop" is used in stop command. Original patch contributed by Ryan DeShone and modified by Yugo Nagata. See [pgpool-hackers: 239][pgpool-hackers: 512]. - Allow to run pgpool_setup and regression test on Ubuntu box (Tatsuo Ishii) - test: Fix -i option (install directory of pgpool) not working (Tatsuo Ishii) - Add missing include file sys/wait.h. (Tatsuo Ishii) Per bug #104. http://www.pgpool.net/mantisbt/view.php?id=104 - Fix an infinite loop of ping error at new active pgpool when virtual IP switching (Yugo Nagata) This bug also caused hangs of the old active pgpool, since this waits response from the new active pgpool, which is in the infinite loop and not able to respond. This problem is reported by Qian Peng in [pgpool-hackers: 520]. - Disable statement_timeout of PostgreSQL while executing online recovery (Tatsuo Ishii) Online recovery may take very long time and user may enable statement timeout. To prevent online recovery canceled by statement timeout, disable statement timeout in the connection used by online recovery. See [pgpool-general: 2919] for more details. - Fix pool_table_name_to_oid in case new to_regclass used which is introduced in PostgreSQL 9.4 (Tatsuo Ishii) The relcache func used here should return 0 if target table is not found. However to_regclass returns NULL in this case. To fix the problem now COALESCE is used. - test: Fix regression test 057 hung if run against PostgreSQL 9.4 or later (Tatsuo Ishii) PostgreSQL 9.4 or later changed libpq behavior: NULL username for connection string does not cause an error, which was expected in the test. - Fix to close pipe when ping command exits with failure (Yugo Nagata) This bug causes pipe open error: Too many open files, which leads to failure of connecting to trusted servers, and then pgpool goes to down status. - Fix Resource leaks (Muhammad Usama) Coverity issue #1222998 and #1222999. - Add a description that pcp_detach_node command disconnects existing sessions (Tatsuo Ishii) - Fix failover.sh produced by pgpool_setup (Tatsuo Ishii) It did not support there's more than 2 nodes case. It always tries to promoto node0 or node1. - Remove meaningless minus check because of unsigned int variable (Tatsuo Ishii) Coverity issue #1111419, #1111420, #1111422. - replacing strcpy() with much safer and recommended call strlcpy() (Muhammad Usama) Coverity issue #1111480. - Fix pgpool.spec to support openssl (Tatsuo Ishii) - Fix pgpool.spec to use 3.3-stable tree head (Tatsuo Ishii) - Remove unnecessary call to pool_shmem_exit() which removes semaphore when it shouldn't (Tatsuo Ishii) exit_handler checks if the process is parent or not. This is good. However, even if it is a child process, it calls pool_shmem_exit() which removes semaphore and shmem when it should not. It should be called only from parent process. Per bug #102. http://www.pgpool.net/mantisbt/view.php?id=102 - Fix get_insert_command_table_name() function not to use freed pointer (Muhammad Usama) Coverity issue #1223007. - Fix pool_handle_query_cache() to not free NULL pointer (Tatsuo Ishii) - Change connect() timeout longer (10 seconds) for flaky network (Tatsuo Ishii) Change connect() timeout in connect_inet_domain_socket_by_port() from 1 second to 10 seconds for flaky network such as AWS. This should help reducing frequent failover. - Fix reset query stuck problem. (Tatsuo Ishii) It is reported that reset query (DISCARD ALL etc.) occasionally does not finish and pgpool child remain waiting for reply from backend thus client cannot connect to pgpool. The cause of problem is not identified yet but if client suddenly closes connection to pgpool in the middle of query processing, backend may not accept the reset queries because they are not ready for query. The fix is, if frontend closes connection in unexpected way, query process loop immediately returns with new state: POOL_END_WITH_FRONTEND_ERROR and pgpool closes connection to PostgreSQL then goes back to new connection request waiting loop. Also, pgpool closes connections to backend when client_idle_limit is set and the idle limit. Per bug #107. http://www.pgpool.net/mantisbt/view.php?id=107 - Fix other dozens of coverity issues (Muhammad Usama) =============================================================================== 3.3.3 (tokakiboshi) 2014/03/24 * Version 3.3.3 This is a bugfix release against pgpool-II 3.3.2. __________________________________________________________________ * Bug fixes - installer: Fix bug that install of pgpool-II RPM fails (Yugo Nagata) - installer: Fix to set up passwordless SSH from apache@localhost to postgres@localhost (Yugo Nagata) - Fix bug that restarted pgpool's watchdog status is regarded as down (Yugo Nagata) - doc: Add mention about "listen queue" and how to increase the "backlog" in the num_init_children section. (Tatsuo Ishii) - Fix bug that watchdog status goes down even when only one of trusted servers get unpingable (Yugo Nagata) - Fix bad performance of unlogged tables detection code. (Tatsuo Ishii) Pointed out at [pgpool-hackers: 435][[pgpool-general:2325]. - Fix primary node detection logic. (Tatsuo Ishii) There's a possibility that primary node is not detected. This happens in following situation. node 0: primary, node 1: standby. Node 0 goes down. Health checking detects the fact but local status is not updated yet. Primary node finding (find_primary_node) runs. Node 0's status is yet healthy. Because find_primary_node fails to connect to node 0, it immediately returns -1 and fails to find that fact that node 1 is now primary. Fix is just continuing to look for primary node when fails to connect to a node. Per [pgpool-general: 2409]. - Add raw mode support to pgpool_setup. (Tatsuo Ishii) - test: Integrate jdbc test to regression test. (Tatsuo Ishii) - Fix jdbc DML fails when operated in raw mode and auto commit is off. (Tatsuo Ishii) This is reported in bug #92. - Fix to output error message when wd_escalation_command fails with exit code other than 0 (Yugo Nagata) This is suggested by Sergey Arlashin in [pgpool-general: 2457]. - test: Add new regression test for query cache. (Tatsuo Ishii) - Fix query cache bug with extended protocol. (Tatsuo Ishii) SELECT retrieves outdated cache even DML was executed in an explicit transaction. The bug had been there since in memory query cache was born. Per [pgpool-general-jp: 1252]. - Add missing entries "relcache_size" and "check_temp_table" to show pool_status (Tatsuo Ishii) - Fix to output error message when if_up_cmd fails. (Yugo Nagata) This is suggested by Sergey Arlashin in [pgpool-general: 2457]. - Avoid to send queries to unrelated nodes in streaming replication mode. (Tatsuo Ishii) Pgpool-II sends certain queries, such as BEGIN, END and SET commands to all of DB nodes. However in streaming replication mode, only primary node and at most one standby node are only concerned (if primacy node is selected as the load balance node, only 1 node is concerned). See [pgpool-hackers: 464] for more details. - Fix possible buffer overrun problem and memory leak. (Tatsuo Ishii) Per Coverity 1111465 and 1111482. - Fix possible buffer overrun. (Tatsuo Ishii) Replace strcpy() with strlcpy(). Per Coverity report 1111478, 1111480, 1111481. - Add debug messages for analyzing errors in if_up_cmd (Yugo Nagata) - Fix freeing NULL. (Tatsuo Ishii) Per Coverity 1111384. - Do not enable query cache on materialized views. (Tatsuo Ishii) Per bug #95. - Fix memory leak. (Tatsuo Ishii) Per Coverity 1111446. - Fix a segmentation fault in parallel mode with system_db_hostname is empty (Yugo Nagata) - Fix to output debug messages in processing pgpool.conf with -d option (Yugo Nagata) Previously, some debug messages in pool_get_config() ware not output even when -d option was used. - Fix JDBC exception of prepared statement including now() in replication mode (Yugo Nagata) With JDBC, when a prepared statement is executed more than PrepareThreshold times, the statement is named and Describe message is sent after Parse. With named statement, pgpool rewrite now() to parameter in replication mode. Hence, rewritten query has additional parameter than original. In this case, ParameterDescription message sent to frontend (response of Describe) should include OIDs of the same number os original query's parameters. Otherwize, JDBC throws ArrayIndexoutOfBoundsException. This is reported in [pgpool-general-jp: 1192]. - Fix backend error of prepared statement about table which has column whose default value is now() in replication mode (Yugo Nagata) When pgpool parses a named prepared statement with default now(), timestamps are replaced to additional parameters. So, Bind message also should included additional parameter format codes. However, when the number of original parameter was one, pgpool didn't handle this. This caused a error like "incorrect binary data format in bind parameter 2". - test: Fix a bug of regression test of JDBC that shows OK even when this fails (Yugo Nagata) - test: Add a new regression test for JDBC's PrepareThreshold (Yugo Nagata) - doc: Add description about parallel mode doesn't support PREPARE (Yugo Nagata) Per bug #93 =============================================================================== 3.3.2 (tokakiboshi) 2013/11/29 * Version 3.3.2 This is a bugfix release against pgpool-II 3.3.1. __________________________________________________________________ * Bug fixes - Fix incorrect time stamp rewriting in replication mode for certain time zones. (Tatsuo Ishii) Time stamp rewriting calls "SELECT now()" to get current time. Unfortunately the buffer for the current time is too small for certain time zones such as "02:30". Note that non-30-minutes-time-zone such as "0900" does not reveal the problem. This explains why we haven't the bug report until today. Bug reported in [pgpool-general: 2113] and fix provided by Sean Hogan. http://www.sraoss.jp/pipermail/pgpool-general/2013-September/002142.html - installer: Fix the way to specify pgpoolAdmin version in redhat/rpm_installer/getsources.sh. (Yugo Nagata) - Makefile: Replace pg_config by $(PG_CONFIG) in Makefiles so it can be overridden at build time when compiling for different PG major versions. (Tatsuo Ishii) Patch contributed by Christoph Berg ([pgpool-general: 2127]). http://www.sraoss.jp/pipermail/pgpool-general/2013-September/002156.html - watchdog: Fix a warning/error when compiling with -Werror=format-security. (Tatsuo Ishii) Patch contributed by Christoph Berg ([pgpool-general: 2127]). http://www.sraoss.jp/pipermail/pgpool-general/2013-September/002156.html - configure: Remove -lcompat because it confuses FreeBSD per bug#15. (Tatsuo Ishii) http://www.pgpool.net/mantisbt/view.php?id=15 - Fix segfault when pgpool.conf does not set log_standby_delay. (Tatsuo Ishii) This is caused by wrong initialization for log_standby_delay in pool_config.l. Per bug#74. http://www.pgpool.net/mantisbt/view.php?id=74 - doc: Modify descriptions about restrictions of parallel mode Multiple rows INSERT using VALUES are not supported in parallel mode. (Yugo Nagata) - Avoid calling find_primary_node_repeatedly() when standby node goes down. (Tatsuo Ishii) This will reduce the time to failover. Per bug #75, patch modified by Tatsuo Ishii. http://www.pgpool.net/mantisbt/view.php?id=75 - Fix data inconsistency problem with native replication mode + extended protocol case. (Tatsuo Ishii) It is reported that concurrent INSERT using JDBC driver causes data difference among database node. This only happens following conditions are all met: 1) Native replication mode 2) Extended protocol used 3) The portal created by parse message is reused by bind message 4) autocommit is on 5) SERIAL (sequence) is used Pgpool-II's parse message function knows it has to lock the target table when INSERT (plus #5) is issued by clients. Unfortunately bind message function did not know it. Once parse/bind/execute finishes, pgpool releases the lock obtained by parse because of #4. JDBC wants to reuse the portal and starts the cycle from bind message, which does not obtain lock. As as result, lock-free INSERT are floating around which causes data inconsistency of course. The solution is, lock the table in bind phase. For this bind needs to issue LOCK in extended protocol. This was a little bit hard because the module (do_command()) to issue internal SQL command (other than SELECT) does not support extended protocol. To solve the problem do_query() is modified so that it accepts other than SELECT because it already accepts extended protocol. The modification is minimum and is only tested for the case called from insert_lock(). I do not recommend to replace every occurrence of do_command () with do_query() at this point. BTW the reason why the bug is not reported is, most users uses JDBC with auto commit = off. In this case, the lock obtained by parse persists until user explicitly issues commit or rollback. Per bug report by Steve Kuekes in [pgpool-general: 2142]. http://www.sraoss.jp/pipermail/pgpool-general/2013-September/002171.html - Fix memory allocation size bug in the code path of query cache. (Tatsuo Ishii) In execute() memory allocation size is too small incertain case. No bug has been reported so far, but certainly this is a bug. - Fix occasional segfault in query cache + extended protocol. (Tatsuo Ishii) When the query is not "cache safe", bind_msg->param_offset was not set in Bind(). However, Execute() unconditionally uses bind_msg->param_offset to convert bind parameters to string so that they can be added to the cached query string and it causes segfault because bind_msg->param_offset is a garbage. Also logic bug to calculate bind_msg->param_offset is corrected. Per bug#76. http://www.pgpool.net/mantisbt/view.php?id=76 - Avoid to run out free query cache hash index entry. (Tatsuo Ishii) If hash index entries are run out, pgpool-II cannot reuse old cache entry because pgpool-II always expects there's at least one empty hash index entry. To mitigate the problem, if free hash index entries are run out, look for victim cache block to reuse the hash index entry. Per bug #70. http://www.pgpool.net/mantisbt/view.php?id=70 - installer: checkEnv() didn't do anything and always returned 0. (Nozomi Anzai) - Fix inappropriate shared memory allocation size for clock hand. (Tatsuo Ishii) The memory for clock hand was allocated as sizeof(pool_fsmm_clock_hand)) which is 8 bytes long because the variable is declared as: static int *pool_fsmm_clock_hand; This is plain wrong. The memory size actually needed is only 4 bytes, which is sizeof(*pool_fsmm_clock_hand)). In other word, the bug allocated unnecessary 4 bytes, which did nothing bd for the execution of program. But a bug is a bug. Per coverity report "1111476 Wrong sizeof argument" - Fix "show pool_status" always shows memqcache_auto_cache_invalidation as 0. (Tatsuo Ishii) Per bug #80. http://www.pgpool.net/mantisbt/view.php?id=80 - Fix error message in read_password_packet(). (Tatsuo Ishii) - watchdog: Fix to pass big parameter by pointer instead of by value at some function. (Yugo Nagata) - Fix memory leak when SSL is requested. (Tatsuo Ishii) When SSL is requested, pgpool child retries to read start up packet. However it does not free the memory for previous start up packet. Per Coverity report "1111443 Resource". - Fix memory leak when do_query() fails in timestamp rewriting. (Tatsuo Ishii) For this purpose free_select_result() is changed to accept NULL argument. Per Coverity report "1111454, 1111455 Resource leak". - Fix load balance bug in replication mode. (Tatsuo Ishii) When load_balance_mode = off, SELECTs including writing function should be sent to all the DB nodes. Per [pgpool-general: 2221]. http://www.sraoss.jp/pipermail/pgpool-general/2013-October/002250.html The bug was introduced in: http://git.postgresql.org/gitweb/?p=pgpool2.git;a=commitdiff;h=1ac45a28258074ea4d9d902aca016f970d31f311 (3.3.1). - watchdog: Fix to put null character at end of ping result string used in watchdog. (Yugo Nagata) - Fix target node selection logic when "DEALLOCATE portal|statement". (Tatsuo Ishii) When "DEALLOCATE portal|statement" is used and last prepared statement or portal was not found, target node selection map is not set. Probably this is not actually harmful because prepared statement or portal was not found is an error case. The bug was there since day 0. Per Coverity report "1111491 Structurally dead code". - Fix range check bug of MAX_NUM_BACKENDS in corner case. (Tatsuo Ishii) MAX_NUM_BACKENDS is the allowed max number of DB nodes (128, at this point). In reality, probably no one ever tried more than 128 DB nodes and that's the reason why nobody noticed. Per Coverity report "1111429, 1111430 and 1111431 Out-of-bounds write". - Do not set/unset fronted connection info for dead backend. (Tatsuo Ishii) Per bug #82. http://www.pgpool.net/mantisbt/view.php?id=82 - Fix that the script forgets to allow public access to pgpool_catalog. (Tatsuo Ishii) The bug prevents inserting data into user tables if pgpool_catalog is created in native replication mode. The bug was there from day 1. I wonder why nobody noticed until today. Per [pgpool-general-jp: 1229]. http://www.sraoss.jp/pipermail/pgpool-general-jp/2013-November/001228.html - doc: Add description that it is recommended to specify multiple servers to trusted_servers. (Yugo Nagata) - Fix uninitialized variable in error case in pool_do_auth(). (Tatsuo Ishii) If there's no valid backend, pgpool will return garbage pid to frontend in auth phase. Actually because no backend is available, frontend will be disconnected later on. So this is harmless. Per Coverity report "1127331 Uninitialized scalar variable". - Fix to add node id range check when issue an error message using node id. (Tatsuo Ishii) Per Coverity report #1111433 "Out-of-bounds read". - Fix buffer overrun bug and resource leak bug of parse_copy_data(). (Tatsuo Ishii) Per Coverity report 1111427 "Out-of-bounds write" and 1111453 "Resource leak". - Fix possible segfault in CopyDataRaws(). (Tatsuo Ishii) Coverity pointed out that if pool_get_id() returns an error, VALID_BACKEND will access out of array. Per Coverity report 1111413 "Memory - illegal accesses". - Fix query cache is enabled and protocol version = 2 case. (Tatsuo Ishii) When the protocol version = 2, we assume that session state is "idle". This is not feasible but no way. I recommend to not use query cache with protocol 2. Per Coverity report 1111488 "Uninitialized scalar variable". - Fix strftime() usage in pool_pools(). (Tatsuo Ishii) The buffer is not large enough as expected by the second parameter. This is not harmless because the format string will not produce longer result string than the buffer. Per Coverity report 1111426 "Out-of-bounds access". - RPM: Improved to specify the versions of pgpool-II and PostgreSQL in the. spec file. (Nozomi Anzai) - Fix resource leak in make_persistent_db_connection. (Tatsuo Ishii) For this purpose, new static function free_persisten_db_connection_memory is added. Per Coverity report #1111468. - Fix a bug that connection check to trusted servers fails when the RTT is very short. (Yugo Nagata) - Fix several small bug fixes detected by Coverity. (Tatsuo Ishii) =============================================================================== 3.3.1 (tokakiboshi) 2013/09/06 * Version 3.3.1 This is a bugfix release against pgpool-II 3.3.0. __________________________________________________________________ * Bug fixes - Fix to add the regression test suite for making tar boll (Tatsuo Ishii) This isn't included in the tar ball of 3.3.0 release. - Fix watchdog test script in regression test (Tatsuo Ishii) - Fix a memory overrun bug (Tatsuo Ishii) This problem is pointed out in [pgpool-general: 1956] by Sean Hogan. [pgpool-general: 1956] memory overrun bug? http://www.sraoss.jp/pipermail/pgpool-general/2013-July/001984.html - Fix a compile error (Yugo Nagata) - Fix child process termination with sig abort when memory query cache is enabled (Tatsuo Ishii) This is due to double free bug that occurs when multiple bind/execute messages come after a parse message. When a parse messages comes, query context is created along with temp cache. The pointer to the temp cache is added to the temp cache array when the query executed. Subsequent bind messages uses the same temp cache pointer. This is the source of double free bug when the cache array discarded. This is reported in Bug track #68 by harukat. #68: child process termination with sigabort when memory_cache_enabled = on http://www.pgpool.net/mantisbt/view.php?id=68 - Add some test cases to regression test (Tatsuo Ishii) - Fix typos of the document in installation of pgpool-recovery section. (Tatsuo Ishii) - Fix a typo of log message (Yugo Nagata) - Fix typos of the japanese document (Yugo Nagata) - Fix to send SELECT to master node only when load_balance_mode is off in replication mode (Tatsuo Ishii) When load_balance_mode is off in replication mode, SELECT queries should be sent to master node only, rather than sent to all nodes in an explicit transaction. This problem is reported in [pgpool-general: 2038] by Rypl Lukas. [pgpool-general: 2038] SELECT sent to both nodes in replication mode http://www.sraoss.jp/pipermail/pgpool-general/2013-August/002066.html - Fix pgpool_setup to work in standalone. (Tatsuo Ishii) =============================================================================== 3.3.0 (tokakiboshi) 2013/07/30 * Version 3.3.0 This is the first version of pgpool-II 3.3 series. That is, a "major version up" from 3.2 series. __________________________________________________________________ * Incompatible changes - All the following are about watchdog. See "New features" section below for details of these changes. - Default monitoring method was changed from query mode to heartbeat mode. - Failover/failback commands are executed in only one pgpool-II. - In default, all the query caches on shared memory are cleared when standby pgpool-II escalates to active. - Database name, user name, and password used for monitoring other pgpool-II by query are specified by dedicated parameters. Previously, template1, recovery_user, and recovery_password are used. __________________________________________________________________ * New features ** Watchdog - Add a new monitoring method using heartbeat signal of UDP packet in lifecheck. (Yugo Nagata) You can select a method from either of two methods, "heartbeat" mode or "query" mode. The heartbeat mode is the new method. In this mode, watchdog monitors other pgpool-II process by using heartbeat signal. Watchdog receives heartbeat signals sent by other pgpool-II periodically. If there are no signal for a certain period, watchdog regards it as failure of the pgpool-II. For redundancy you can use multiple networks for heartbeat exchange between pgpool-IIs. This mode is default and recommended one. The query mode is the conventional method. In this mode, watchdog monitors pgpool-II's service rather than process. Watchdog sends queries to other pgpool-II and checks the response. Note that this method requires connections from other pgpool-IIs, so it would fail motoring if num_init_children isn't large enough. This mode is deprecated and left for backward compatibility. Add these new parameters: - wd_lifecheck_method - wd_heartbeat_port - wd_heartbeat_keepalive - wd_heartbeat_deadtime - heartbeat_destinationX - heartbeat_destination_portX - heartbeat_deviceX - Add interlocking mechanism of exclusive failover/failback command execution. (Yugo Nagata) When using multiple pgpool-IIs with watchdog enabled, failover commands (failover_command, failback_command, and follow_master_command) get executed only at one pgpool-II. Previously, these command got executed at all pgpool-IIs. - Add authentication mechanism for watchdog packet communication. (Yugo Nagata) Watchdog packets (include heartbeat signal) from pgpool-II with wrong authentication key are rejected. All pgpool-IIs must have the same key, which is specified wd_authkey parameter in pgpool.conf. pgpool-II with wrong authkey can't even start watchdog, because the startup packet is rejected by other pgpool-IIs. - Add clear_memqcache_on_escalation parameter. (Yugo Nagata) If this is on, all the query caches on shared memory are cleared when standby pgpool-II escalates to active. This is aimed to prevent the new active pgpool-II from using inconsistent query caches with the previous active. - Add wd_escalation_command parameter. (Yugo Nagata) This specifies command which is executed at escalation on the new active pgpool-II server. The timing is just before virtual IP is brought up. - Add parameters wd_lifecheck_dbname, wd_lifecheck_user, and wd_lifecheck_password. (Yugo Nagata) These parameters specify the database name, the user name, and password used in query mode lifecheck of watchdog . Previously, these are hard coded to use template1, recovery_user, and recovery_password. - When delegate_IP parameter is empty, virtual IP is neither brought up nor switched. (Yugo Nagata) This allows multi-master like configuration without virtual IP. - Add pcp_watchdog_info command (Yugo Nagata) This is PCP command for retrieving the watchdog status. ** Others - Import PostgreSQL 9.2 raw parser. (Nozomi Anzai, Tatsuo Ishii) - Add a tool called pgpool_setup to set up pgpool-II and PostgreSQL temporary installation in current directory for *testing* purpose. (Tatsuo Ishii) usage: pgpool_setup [-m r|s][-n num_clusters][--no-stop] -m s: create an installation as streaming replication mode. (the default) -m r: create an installation as native replication mode. -n num_clusters: create num_clusters PostgreSQL database cluster nodes -p base_port: specify base port. The first PostgreSQL node's port is base_port. Second PostgreSQL node's port is base_port+1 ... nth PostgreSQL node's port is base_port+n-1, pgpool port is base_port+n, pcp port is base_port+n+1. --no-stop: do not stop pgpool and PostgreSQL after the work - Support installation method using CREATE EXTENSION for pgpool-recovery and pgpool-regclass. (Tatsuo Ishii) Older installation method is still preserved. Note: extension names are "pgpool_recovery" and "pgpool_regclass", not "pgpool-recovery" and "pgpool-regclass" because letters are not convenient in using CREATE EXTENSION command (requires double quotes). - Add a function "pgpool_pgctl()" which enables to execute pg_ctl stop/restart/reload (except for start) by SQL. (Nozomi Anzai) $ psql sales -c "select pgpool_pgctl('reload', 'fast')"; pgpool_pgctl -------------- t (1 row) This function always ignores the actual result and returns 't', so the user can't know if pg_ctl succeeded or failed. To use this we have to set the custom variable for security which limits the users to execute pg_ctl who has the permission of data directory. - Add shell scripts to install pgpool-II and pgpoolAdmin by RPM. (Nozomi Anzai, Yugo Nagata) To make the installer package execute getsources.sh, and the directory named "work" will be created. And you rpmbuild each spec files in work/, put RPMs into work/installer and make tar ball of work/installer. The installer does not only install RPMs but also edit postgresql.conf, pgpool.conf, pg_hba.conf, recovery.conf and scripts for failover and online recovery. This assumes two-nodes configuration and the install script have to be executed in both nodes. - Add new parameter "search_primary_node_timeout". (Muhammad Usama, Tatsuo Ishii) The parameter specifies the maximum amount of time in seconds to search for a primary node when a failover scenario occurs. Patch contributed by Muhammad Usama. Japanese doc and slight editing of English doc by Tatsuo Ishii. - Chinese tutorials for memqcache and watchdog. (Bambo Huang) - Add regression test suit. (Tatsuo Ishii) __________________________________________________________________ * Bug fixes - Consider timeout waiting for completion of failback request in on line recovery. (Tatsuo Ishii) This will prevent the situation that recovery operation continues forever and we cannot even shutdown pgpool-II main process. This could happen especially while executing follow master command. - Fix a bug that %H of follow_master_command is not assigned correctly the new primary node in stream replication mode. (Tatsuo Ishii) - Fix not to execute escalation when the pgpool-II which is already active receives down notification from other pgpool-II. (Yugo Nagata) - Fix wd_create_send_socket() not to execute select() before connect(). (Yugo Nagata) How select() works on an unconnected socket is undefined, and differs between platform. On Linux, this returns 2 and it is eventually harmless. However, on Soraris, this returns 0 and it is indistinguishable from time timeout, so watchdog wouldn't work correctly. - Fix error when pgpool_regclass is not installed. (Tatsuo Ishii) The query used in pool_has_pgpool_regclass() fails if pgpool_regclass does not exist. The bug was introduced in 3.2.4. See [pgpool-general: 1722] for more details. [pgpool-general: 1722] [PgPool-II 3.2.4] pgpool_regclass now mandatory? http://www.sraoss.jp/pipermail/pgpool-general/2013-May/001749.html - Fix do_query() not to hang when PostgreSQL returns an error. (Tatsuo Ishii) The typical symptom is "I see SELECT is keep on running according to pg_stat_activity". To fix this pgpool-II just exits the process and kill the existing connection. This is not gentle but at this point I believe this is the best solution. - Fix possible deadlock during failover with watchdog enabled. (Yugo Nagata) This is reported in Bug track #54 by arshu arora http://www.pgpool.net/mantisbt/view.php?id=54 - Fix unnecessary degeneration caused by error on commit. (Tatsuo Ishii) In master slave mode, if master gets an error at commit, while other slaves are normal at commit, we don't need to degenerate any backend because it is likely that the "kind mismatch error" was caused by a deferred trigger. - Fix bug with do_query which causes hung in extended protocol. (Tatsuo Ishii) This problem could occur when insert lock is enabled and pgpool_catalog.insert_lock exists, See [pgpool-general: 1684] for more details. [pgpool-general: 1684] insert_lock hangs http://www.sraoss.jp/pipermail/pgpool-general/2013-May/001711.html - Fix possible failure of query cache invalidation for DML in transaction. (Tatsuo Ishii) CREATE TABLE t1(i INTEGER); CREATE TABLE t2(i INTEGER); SELECT * FROM t1; BEGIN; DELETE FROM t2 WHERE i = 0; INSERT INTO t1(i) VALUES(1); COMMIT; SELECT * FROM t1; At commit pgpool tries to delete cache for t2 but fails because there's no oid table entry for t2. Problem is, it fails to check oid table for t1. So cache for t1 remains and the last SELECT incorrectly returns cached data. Fix is, continuing to check oid table entries. This is reported in Bug track #58 by wms http://www.pgpool.net/mantisbt/view.php?id=58 - Fix to register pgpool_regclass in pg_catalog schema (Tatsuo Ishii) This is necessary to deal with clients which restricts schema search path to pg_catalog only. Postgres_fdw is such a client. - Fix a hang of "pgpool -m f stop" (Tatsuo Ishii) This is caused by unmanaged pgpool children remaining. This could happen when multiple PostgreSQLs are going down or even when pgpool is started before PostgreSQL startup. - Fix a potential crash in pg_md5 command (Muhammad Usama) - Fix a segmentation fault that occurs when on memory query cache enabled and the query is issued in extended query mode and the result is too large (Tatsuo Ishii) This is reported in Bug track #63 by harukat. Analysis and a test case are also provided. #63 Child process was terminated by segmentation fault with memcached http://www.pgpool.net/mantisbt/view.php?id=63 - Fix a segmentation fault of a child process that occurs when a startup packet has no PostgreSQL user information (Yugo Nagata) You can reproduce it by $ psql -p 9999 -U '' If enable_pool_hba is on, a child process terminates by segmentation fault. Otherwise if enable_pool_hba is off, the error message is ERROR: pool_discard_cp: cannot get connection pool for user (null) database (null) In both cases, psql terminates with no message on frontend. In the fixed version, if PostgreSQL user is not specified in startup packet, the message as following is output to both log and frontend. This is the same behavior as PostgreSQL. FATAL: no PostgreSQL user name specified in startup packet - Fix memory allocation logic in extended query processing with on-memory query cache enabled (Tatsuo Ishii) When very long query string (> 1024 bytes) supplied in extended query with bind parameters, it fails to allocate enough memory. - Fix to verify the backend node number in pcp_recovery_node (Yugo Nagata) When an invalid number is used, null value is passed as an arguments of recovery script, and this causes a malfunction. In especially, rsync may delete unrelated files in basebackup scripts. - Fix a segmentation fault on main process that could occurs after backend error detection (Tatsuo Ishii) This is reported in Bug track #62 by tuomas. #62 Slave network outage causes a segmentation fault on main process http://www.pgpool.net/mantisbt/view.php?id=62 - Fix bug with health check when used with child_life_time (Tatsuo Ishii) Failover could happen even if the backend was running fine. This problem is reported in [pgpool-general: 1892] by larisa sabban. [pgpool-general: 1892] Pgpool is unable to connect backend PostgreSQL http://www.sraoss.jp/pipermail/pgpool-general/2013-July/001920.html - Fix bug in parsing prepared statements with transaction handling in replication mode (Tatsuo Ishii) Parse() automatically starts a transaction for non SELECT query to keep consistency among nodes in replication mode. But this wasn't closed. If wrong query comes in, the transaction goes into an abort state but pgpool does not close the transaction. Thus next query causes error because the transaction is still in abort status. This problem was reported in [pgpool-general: 1877] by Sean Hogan. [pgpool-general: 1877] current transaction is aborted, commands ignored http://www.sraoss.jp/pipermail/pgpool-general/2013-July/001905.html __________________________________________________________________ * Enhancements - Add mention about "-D" option to the man page. (Tatsuo Ishii) - Fix to restart watchdog processes automatically when these exit abnormally. (Yugo Nagata) - Add more error checks and reportings to functions executing ping command with watchdog enabled. (Tatsuo Ishii) - Replace some unsafe functions, sprintf and strncpy, with more safe ones, snprintf and strlcpy respectively. (Yugo Nagata) - Replace "sticky bit" to "setuid bit" in log message, comments and function names. (Yugo Nagata) These words were used mistakenly and caused confusion. - Fix description on SSL in pool_hba.conf.sample. (Tatsuo Ishii) - Allow to load balancing in an explicit transaction in replication mode. (Tatsuo Ishii) The condition to allow the load balancing is as follows: 1) replicate_select is off 2) no writing functions are used 3) transaction isolation level is not serializable 4) no DML/DDL are issued in the transaction - Chinese manual is updated to the latest especially about watchdog. (Bambo Huang) - Add mention about "-D" option to the man page. (Tatsuo Ishii) - Move ssl_ca_cert and ssl_ca_cert_dir descriptions to the SSL section in the document (Yugo Nagata) - Add ssl_ca_cert and ssl_ca_cert_dir descriptions to the japanese document (Yugo Nagata) =============================================================================== 3.2 Series (2012/08/03 - ) =============================================================================== 3.2.17 (namameboshi) 2016/08/31 * Version 3.2.17 This is a bugfix release against pgpool-II 3.2.16. __________________________________________________________________ * Bug fixes - Fix buffer over run problem in "show pool_nodes". (Tatsuo Ishii) While processing "show pool_nodes", the buffer for hostname was too short. It should be same size as the buffer used for pgpool.conf. Problem reported by a twitter user who is using pgpool on AWS (which could have very long hostname). - Fix usage of wait(2) in pgpool main process. (Tatsuo Ishii) The usage of wait(2) in pgpool main could cause infinite wait in the system call. Solution is, to use waitpid(2) instead of wait(2). - Fix "kind mismatch" error message in pgpool. (Muhammad Usama) Many of "kind mismatch..." errors are caused by notice/warning messages produced by one or more of the DB nodes. In this case now Pgpool-II forwards the messages to frontend, rather than throwing the "kind mismatch..." error. This would reduce the chance of "kind mismatch..." errors. See [pgpool-hackers: 1501] for more details. - Replace "MAJOR" macro to prevent occasional failure. (Tatsuo Ishii) The macro calls pool_virtual_master_db_node_id() and then access backend->slots[id]->con using the node id returned. In rare cases, it could point to 0 (in case when the DB node is not connected), which gives access to con->major, then it causes a segfault. See bug 225 for related info. - doc : fix Japanese document typo. (Bo Peng) - Fixing a typo in the log message. (Muhammad Usama) - doc : Add comment to the document about connection_cache. (Tatsuo Ishii) =============================================================================== 3.2.16 (namameboshi) 2016/06/17 * Version 3.2.16 This is a bugfix release against pgpool-II 3.2.15. __________________________________________________________________ * New features - Allow to access to pgpool while doing health checking (Tatsuo Ishii) Currently any attempt to connect to pgpool fails if pgpool is doing health check against failed node even if fail_over_on_backend_error is off because pgpool child first tries to connect to all backend including the failed one and exits if it fails to connect to a backend (of course it fails). This is a temporary situation and will be resolved before pgpool executes failover. However if the health check is retrying, the temporary situation keeps longer depending on the setting of health_check_max_retries and health_check_retry_delay. This is not good. Attached patch tries to mitigate the problem: - When an attempt to connect to backend fails, give up connecting to the failed node and skip to other node, rather than exiting the process if operating in streaming replication mode and the node is not primary node. - Mark the local status of the failed node to "down". - This will let the primary node be selected as a load balance node and every queries will be sent to the primary node. If there's other healthy standby nodes, one of them will be chosen as the load balance node. - After the session is over, the child process will suicide to not retain the local status. * Bug fixes - Fix is_set_transaction_serializable() when SET default_transaction_isolation TO 'serializable'. (Bo Peng) SET default_transaction_isolation TO 'serializable' is sent to not only primary but also to standby server in streaming replication mode, and this causes an error. Fix is, in streaming replication mode, SET default_transaction_isolation TO 'serializable' is sent only to the primary server. See bug 191 for related info. - Fix Chinese documentation bug about raw mode (Yugo Nagata, Bo Peng) Connection pool is available in raw mode. - Fix confusing comments in pgpool.conf (Tatsuo Ishii) - Permit pgpool to support multiple SSL cipher protocols (Muhammad Usama) Currently TLSv1_method() is used to initialize the SSL context, that puts an unnecessary limitation to allow only TLSv1 protocol for SSL communication. While postgreSQL supports other ciphers protocols as well. The commit changes the above and initializes the SSLSession using the SSLv23_method() (same is also used by PostgreSQL). Because it can negotiate the use of the highest mutually supported protocol version and remove the limitation of one specific protocol version. - If statement timeout is enabled on backend and do_query() sends a (Tatsuo Ishii) query to primary node, and all of following user queries are sent to standby, it is possible that the next command, for example END, could cause a statement timeout error on the primary, and a kind mismatch error on pgpool-II is raised. This fix tries to mitigate the problem by sending sync message instead of flush message in do_query(), expecting that the sync message reset the statement timeout timer if we are in an explicit transaction. We cannot use this technique for implicit transaction case, because the sync message removes the unnamed portal if there's any. Plus, pg_stat_statement will no longer show the query issued by do_query() as "running". See bug 194 for related info. - Deal with the case when the primary is not node 0 in streaming replication mode. (Tatsuo Ishii) http://www.pgpool.net/mantisbt/view.php?id=194#c837 reported that if primary is not node 0, then statement timeout could occur even after bug194-3.3.diff was applied. After some investigation, it appeared that MASTER macro could return other than primary or load balance node, which was not supposed to happen, thus do_query() sends queries to wrong node (this is not clear from the report but I confirmed it in my investigation). pool_virtual_master_db_node_id(), which is called in MASTER macro returns query_context->virtual_master_node_id if query context exists. This could return wrong node if the variable has not been set yet. To fix this, the function is modified: if the variable is not either load balance node or primary node, the primary node id is returned. - change the Makefile under the directory src/sql/, that is proposed (Bo Peng) by [pgpool-hackers: 1611] - Fix a possible hang during health checking (Yugo Nagata) Health checking was hang when any data wasn't sent from backend after connect(2) succeeded. To fix this, pool_check_fd() returns 1 when select(2) exits with EINTR due to SIGALRM while health checking is performed. Reported and patch provided by harukat and some modification by Yugo. Per bug #204. backported from 3.4 or later; https://git.postgresql.org/gitweb/?p=pgpool2.git;a=commitdiff;h=ed9f2900f1b611f5cfd52e8f758c3616861e60c0 - Fix bug with load balance node id info on shmem (Tatsuo Ishii) There are few places where the load balance node was mistakenly put on wrong place. It should be placed on: ConnectionInfo *con_info[child id, connection pool_id, backend id].load_balancing_node]. In fact it was placed on: *con_info[child id, connection pool_id, 0].load_balancing_node]. As long as the backend id in question is 0, it is ok. However while testing pgpool-II 3.6's enhancement regarding failover, if primary node is 1 (which is the load balance node) and standby is 0, a client connecting to node 1 is disconnected when failover happens on node 0. This is unexpected and the bug was revealed. It seems the bug was there since long time ago but it had not found until today by the reason above. =============================================================================== 3.2.15 (namameboshi) 2016/04/26 * Version 3.2.15 This is a bugfix release against pgpool-II 3.2.14. __________________________________________________________________ * Bug fixes - Removing the limit on the maximum number of items in the black_function_list and white_function_list lists. (Muhammad Usama) extract_string_tokens in pool_config uses the fixed size malloc on the array to hold the black_function_list/white_function_list items. This imposes a limit of maximum items in these lists. The fix is to use realloc to increase the array size when it gets full. - Redirect all user queries to primary server (Tatsuo Ishii) Up to now some user queries are sent to other than the primary server even if load_balance_mode = off. This commit changes the behavior: if load_balance_mode = off in streaming replication mode, now all the user queries are sent to the primary server only. Per bug #189. - Change the PID length of pcp_proc_count command result to 6 characters long (Bo Peng) If the pgpool process ID are over 5 characters, the 6th character of each process ID will be removed. This commit changes the process ID length of pcp_proc_count command result to 6 characters long. Per bug #188. =============================================================================== 3.2.14 (namameboshi) 2016/04/04 * Version 3.2.14 This is a bugfix release against pgpool-II 3.2.13. __________________________________________________________________ * Bug fixes - doc: Change description of backend_flag (Tatsuo Ishii) It is pointed out that restarting pgpool-II is not necessary. Per [pgpool-general-jp: 1394]. - doc: Fix installation procedure. (Tatsuo Ishii) With PostgreSQL 9.4 or later, installing pgpool_regclass is not needed. - Fix to validate the PCP packet length (Muhammad Usama) Without the validation check, a malformed PCP packet can crash the PCP child and/or can run the server out of memory by sending the packet with a very large data size. - Fix a reset query stuck problem (Muhammad Usama) The solution is to return POOL_END_WITH_FRONTEND_ERROR instead of POOL_END when pool_flush on front-end socket fails. The original report is [pgpool-general: 4265] Pgpool - connection hangs in DISCARD ALL =============================================================================== 3.2.13 (namameboshi) 2016/02/05 * Version 3.2.13 This is a bugfix release against pgpool-II 3.2.12. __________________________________________________________________ * Bug fixes - doc: Fix misinformation regarding load balancing in docs (Tatsuo Ishii) In streaming replication mode, DECLARE, FETCH, CLOSE and SHOW are sent to primary node only. Pointed out in [pgpool-general-jp: 1378]. - Issue fsync() when writing pgpool_status (Tatsuo Ishii) This ensures that pgpool_status is saved to permanent storage and allow to survive after system crash. - Fix ancient bug of pool_push() and friends (Tatsuo Ishii) It allocates buffer using realloc and uses the pointer returned. However it does the pointer calculation *before* realloc gets called. So the calculation uses the old pointer value, which causes various problems including segfault later. Also there were other problems with it. The buffer pointer and buffer size variable is not initialized. The buffer is not freed by pool_close. Typo in debugging message (3.4 or later only). They are fixed as well. - doc: Fix wrong description about log_standby_delay in the document (Yugo Nagata) - Fix bug with "SET TRANSACTION READ ONLY" (Tatsuo Ishii) Pgpool-II remembers that non read only queries (including SET) were executed in an explicit transaction and adds a "writing transaction" mark to the transaction. The mark affects the query routing behavior of pgpool-II while running in streaming replication mode. Pgpool-II starts sending queries to the primary after the mark is set. Because the effect of writing queries may appear on standbys after some delay in streaming replication mode, it is safer to route read queries to the primary after the mark is set. However there's oversight here. "SET TRANSACTION READ ONLY" does no data modification and should be treated as an exception. Per bug #157. - Fix FATAL error with reloading (Tatsuo Ishii) While reloading pgpool.conf, the number of DB nodes is tentatively set to 0, then counted up until reaching to the actual number of backends by the pgpool main process. Unfortunately the variable was on the shared memory and it confused pgpool child process when they were using the variable and this caused FATAL error. Per bug #156 report by harukat. - doc: Add restriction about starting multiple pgpool simultaneously (Yugo Nagata) - Fix a in-memory query cache bug (Tatsuo Ishii) If extended query protocol is used and a bind/execute message arrives which uses a statement created by prior parse message, the temp_cache is not initialized by a parse messages. Thus messages are added to pre existing temp cache buffer which causes the trouble, that is, when the cached result returns, Data Row message and Command Complete message appeared twice. Per by bug #152. - Ignore close statement/portal request if they do not exist (Tatsuo Ishii) In this case just returns a close complete message to client. This is a back port of the following commit from pgpool-II 3.4: 1a37e1c35bd8b6f10f524693bbcb7b51f73b4bf0 =============================================================================== 3.2.12 (namameboshi) 2015/07/24 * Version 3.2.12 This is a bugfix release against pgpool-II 3.2.11. __________________________________________________________________ * Bug fixes - Fix "cannot find xlog functions" error in pgpool-recovery (Muhammad Usama) The argument data type of PostgreSQL's pg_xlogfile_name() function has been changed from text to pg_lsn since PostgreSQL 9.4. And pgpool-recovery was still trying to locate the function by old signature. - Pass empty string parameters in failover command when pgpool-II does not have a value for any particular parameter (Muhammad Usama) Instead of omitting the values for the parameters when pgpool-II does not have any value for a particular parameter, it now passes an empty string to the failover command. This makes sure that failover script will always receive the exact number of expected parameters. - doc: Fix outdated limitation description about load balancing using JDBC driver (Tatsuo Ishii) Even if autocommit is false, load balancing is possible in certain conditions. - Allow to use in-memory query cache size more than 4GB (Tatsuo Ishii) This should have been allowed since in memory query cache was born. - Do not send a query for checking insert lock in non replication mode with extended query (Tatsuo Ishii) =============================================================================== 3.2.11 (namameboshi) 2015/04/08 * Version 3.2.11 This is a bugfix release against pgpool-II 3.2.10. __________________________________________________________________ * Bug fixes - Fix to use void * type for receiving return value of thread function (Yugo Nagata) Previously int type was used and this could occur stack buffer overflow. This caused an infinity loop of ping error at bringing up or down VIP. - Fix to set SIGCHLD to SIG_DFL instead of SIG_IGN in watchdog processes (Yugo Nagata) When using waitpid, it isn't necessary to set SIGCHLD to SIG_IGN. Rather, it is harmful, and due to this it was regarded that ping command exited abnormally in error even when this succeeded. - Remove an unnecessary include directive (Yugo Nagata) - Enlarge POOLCONFIG_MAXDESCLEN to 80 (Tatsuo Ishii) This is used in show pool_status command and limits the length of parameter description. Unfortunately recovery_timeout description is 64 chars, which is 1 byte longer than former definition of the macro. - Support SSL certificate chains in the certificate file for incoming frontend connections (Muhammad Usama) - Fix a problem with pcp_detach_node about graceful node detach (Muhammad Usama) When graceful node detach is requested gracefully, pcp_detach_node should check if it is allowed to process detach_node command on the particular node before blocking the incoming connections and closing the existing connections. =============================================================================== 3.2.10 (namameboshi) 2015/02/05 * Version 3.2.10 This is a bugfix release against pgpool-II 3.2.9. __________________________________________________________________ * Bug fixes - doc: Describe explicitly that the number of slave nodes is not necessarily 1 (Tatsuo Ishii) - Fix uninitialized variable (Tatsuo Ishii) Per Coverity 1234603. - doc: Fix missing release note entries in the previous release (Tatsuo Ishii) - Fix possible segmentation fault in query cache (Tatsuo Ishii) - Fix node id range check bug in trigger_failover_command(). (Tatsuo Ishii) The node id should be lower than NUM_BACKENDS. Probably harmless since callers never pass node ids greater or equal to NUM_BACKENDS. - Allow $_IP_$ having address prefix in if_up_cmd and if_down_cmd (Muhammad Usama) Previously, it is assumed that "$_IP_$" keyword will always have a white space at the end, and when "$_IP_$" has address prefix (e.g. $_IP_$/24), this prefix was ignored. Per bug #122. http://www.pgpool.net/mantisbt/view.php?id=122 - Allow "show pool_nodes" to print node ids having more than one digits (Muhammad Usama) Problem reported in [pgpool-general: 3374]. - Fix to disable debug mode by reloading config (Yugo Nagata) Per bug #114 http://www.pgpool.net/mantisbt/view.php?id=114 =============================================================================== 3.2.9 (namameboshi) 2014/09/05 * Version 3.2.9 This is a bugfix release against pgpool-II 3.2.8. __________________________________________________________________ * Bug fixes - Fix a typo of pgpool.spec (Yugo Nagata) - Fix bug that worker child process keeps failing when there's no primary backend (Tatsuo Ishii) Problem identified and fix contributed by Junegunn Choi. See [pgpool-hackers: 471] for more details. - Close listen socket when smart shutdown request is made (Tatsuo Ishii) When smart shutdown process starts, pgpool children still listen on the port and clients can send further connection requests which fail in the end. Which is not only waste of time, but also prevents a load balancer which sits in front of pgpool from realizing the pgpool is going down. Problem analyzed and patch provided by Junegunn Choi in [pgpool-hackers 474], and enhanced to take care not only inet domain socket but UNIX domain socket by Tatsuo Ishii. - doc: Add cautions that recovery commands are killed by statement_timeout of PostgreSQL. (Tatsuo Ishii) - doc: Remove old restriction description which is no longer true (Tatsuo Ishii) - Fix return type of text_to_lsn() function (Yugo Nagata) This caused compile warning. - Fix file descriptor leak when daemonize. (Tatsuo Ishii) Per Coverity 1111471. - Fix memory leak. (Tatsuo Ishii) Per Coverity 1111442. - Fix pgpool.init's long-standing bug of stop/restart failure (Yugo Nagata) In previous, pgpool.init uses killproc for stopping pgpool, but there are several problems. In the new version, "pgpool -m fast stop" is used in stop command. Original patch contributed by Ryan DeShone and modified by Yugo Nagata. See [pgpool-hackers: 239][pgpool-hackers: 512]. - Add missing include file sys/wait.h. (Tatsuo Ishii) Per bug #104. http://www.pgpool.net/mantisbt/view.php?id=104 - Disable statement_timeout of PostgreSQL while executing online recovery (Tatsuo Ishii) Online recovery may take very long time and user may enable statement timeout. To prevent online recovery canceled by statement timeout, disable statement timeout in the connection used by online recovery. See [pgpool-general: 2919] for more details. - Remove unnecessary call to pool_shmem_exit() which removes semaphore when it shouldn't (Tatsuo Ishii) exit_handler checks if the process is parent or not. This is good. However, even if it is a child process, it calls pool_shmem_exit() which removes semaphore and shmem when it should not. It should be called only from parent process. Per bug #102. http://www.pgpool.net/mantisbt/view.php?id=102 - Fix reset query stuck problem. (Tatsuo Ishii) It is reported that reset query (DISCARD ALL etc.) occasionally does not finish and pgpool child remain waiting for reply from backend thus client cannot connect to pgpool. The cause of problem is not identified yet but if client suddenly closes connection to pgpool in the middle of query processing, backend may not accept the reset queries because they are not ready for query. The fix is, if frontend closes connection in unexpected way, query process loop immediately returns with new state: POOL_END_WITH_FRONTEND_ERROR and pgpool closes connection to PostgreSQL then goes back to new connection request waiting loop. Also, pgpool closes connections to backend when client_idle_limit is set and the idle limit. Per bug #107. http://www.pgpool.net/mantisbt/view.php?id=107 =============================================================================== 3.2.8 (namameboshi) 2014/03/24 * Version 3.2.8 This is a bugfix release against pgpool-II 3.2.7. __________________________________________________________________ * Bug fixes - doc: Add mention about "listen queue" and how to increase the "backlog" in the num_init_children section. (Tatsuo Ishii) - Fix bug that watchdog status goes down even when only one of trusted servers get unpingable (Yugo Nagata) - Fix bad performance of unlogged tables detection code. (Tatsuo Ishii) Pointed out at [pgpool-hackers: 435][[pgpool-general:2325]. - Fix primary node detection logic. (Tatsuo Ishii) There's a possibility that primary node is not detected. This happens in following situation. node 0: primary, node 1: standby. Node 0 goes down. Health checking detects the fact but local status is not updated yet. Primary node finding (find_primary_node) runs. Node 0's status is yet healthy. Because find_primary_node fails to connect to node 0, it immediately returns -1 and fails to find that fact that node 1 is now primary. Fix is just continuing to look for primary node when fails to connect to a node. Per [pgpool-general: 2409]. - Fix jdbc DML fails when operated in raw mode and auto commit is off. (Tatsuo Ishii) This is reported in bug #92. - Fix query cache bug with extended protocol. (Tatsuo Ishii) SELECT retrieves outdated cache even DML was executed in an explicit transaction. The bug had been there since in memory query cache was born. Per [pgpool-general-jp: 1252]. - Add missing entries "relcache_size" and "check_temp_table" to show pool_status (Tatsuo Ishii) - Avoid to send queries to unrelated nodes in streaming replication mode. (Tatsuo Ishii) Pgpool-II sends certain queries, such as BEGIN, END and SET commands to all of DB nodes. However in streaming replication mode, only primary node and at most one standby node are only concerned (if primacy node is selected as the load balance node, only 1 node is concerned). See [pgpool-hackers: 464] for more details. - Fix possible buffer overrun problem and memory leak. (Tatsuo Ishii) Per Coverity 1111465 and 1111482. - Fix possible buffer overrun. (Tatsuo Ishii) Replace strcpy() with strlcpy(). Per Coverity report 1111478, 1111480, 1111481. - Fix freeing NULL. (Tatsuo Ishii) Per Coverity 1111384. - Do not enable query cache on materialized views. (Tatsuo Ishii) Per bug #95. - Fix memory leak. (Tatsuo Ishii) Per Coverity 1111446. - Fix a segmentation fault in parallel mode with system_db_hostname is empty (Yugo Nagata) - Fix to output debug messages in processing pgpool.conf with -d option (Yugo Nagata) Previously, some debug messages in pool_get_config() ware not output even when -d option was used. - Fix JDBC exception of prepared statement including now() in replication mode (Yugo Nagata) With JDBC, when a prepared statement is executed more than PrepareThreshold times, the statement is named and Describe message is sent after Parse. With named statement, pgpool rewrite now() to parameter in replication mode. Hence, rewritten query has additional parameter than original. In this case, ParameterDescription message sent to frontend (response of Describe) should include OIDs of the same number os original query's parameters. Otherwize, JDBC throws ArrayIndexoutOfBoundsException. This is reported in [pgpool-general-jp: 1192]. - Fix backend error of prepared statement about table which has column whose default value is now() in replication mode (Yugo Nagata) When pgpool parses a named prepared statement with default now(), timestamps are replaced to additional parameters. So, Bind message also should included additional parameter format codes. However, when the number of original parameter was one, pgpool didn't handle this. This caused a error like "incorrect binary data format in bind parameter 2". - doc: Add description about parallel mode doesn't support PREPARE (Yugo Nagata) Per bug #93 =============================================================================== 3.2.7 (tokakiboshi) 2013/12/06 * Version 3.2.7 This is a bugfix release against pgpool-II 3.2.6. __________________________________________________________________ * Bug fixes - Fix incorrect time stamp rewriting in replication mode for certain time zones. (Tatsuo Ishii) Time stamp rewriting calls "SELECT now()" to get current time. Unfortunately the buffer for the current time is too small for certain time zones such as "02:30". Note that non-30-minutes-time-zone such as "0900" does not reveal the problem. This explains why we haven't the bug report until today. Bug reported in [pgpool-general: 2113] and fix provided by Sean Hogan. http://www.sraoss.jp/pipermail/pgpool-general/2013-September/002142.html - Makefile: Replace pg_config by $(PG_CONFIG) in Makefiles so it can be overridden at build time when compiling for different PG major versions. (Tatsuo Ishii) Patch contributed by Christoph Berg ([pgpool-general: 2127]). http://www.sraoss.jp/pipermail/pgpool-general/2013-September/002156.html - Remove -lcompat because it confuses FreeBSD per bug#15. (Tatsuo Ishii http://www.pgpool.net/mantisbt/view.php?id=15 - Fix segfault when pgpool.conf does not set log_standby_delay. (Tatsuo Ishii) This is caused by wrong initialization for log_standby_delay in pool_config.l. Per bug#74. http://www.pgpool.net/mantisbt/view.php?id=74 - doc: Modify descriptions about restrictions of parallel mode Multiple rows INSERT using VALUES are not supported in parallel mode. (Yugo Nagata) - Avoid calling find_primary_node_repeatedly() when standby node goes down. (Tatsuo Ishii) This will reduce the time to failover. Per bug #75, patch modified by Tatsuo Ishii. http://www.pgpool.net/mantisbt/view.php?id=75 - Fix data inconsistency problem with native replication mode + extended protocol case. (Tatsuo Ishii) It is reported that concurrent INSERT using JDBC driver causes data difference among database node. This only happens following conditions are all met: 1) Native replication mode 2) Extended protocol used 3) The portal created by parse message is reused by bind message 4) autocommit is on 5) SERIAL (sequence) is used Pgpool-II's parse message function knows it has to lock the target table when INSERT (plus #5) is issued by clients. Unfortunately bind message function did not know it. Once parse/bind/execute finishes, pgpool releases the lock obtained by parse because of #4. JDBC wants to reuse the portal and starts the cycle from bind message, which does not obtain lock. As as result, lock-free INSERT are floating around which causes data inconsistency of course. The solution is, lock the table in bind phase. For this bind needs to issue LOCK in extended protocol. This was a little bit hard because the module (do_command()) to issue internal SQL command (other than SELECT) does not support extended protocol. To solve the problem do_query() is modified so that it accepts other than SELECT because it already accepts extended protocol. The modification is minimum and is only tested for the case called from insert_lock(). I do not recommend to replace every occurrence of do_command () with do_query() at this point. BTW the reason why the bug is not reported is, most users uses JDBC with auto commit = off. In this case, the lock obtained by parse persists until user explicitly issues commit or rollback. Per bug report by Steve Kuekes in [pgpool-general: 2142]. http://www.sraoss.jp/pipermail/pgpool-general/2013-September/002171.html - Fix memory allocation size bug in the code path of query cache. (Tatsuo Ishii) In execute() memory allocation size is too small incertain case. No bug has been reported so far, but certainly this is a bug. - Fix occasional segfault in query cache + extended protocol. (Tatsuo Ishii) When the query is not "cache safe", bind_msg->param_offset was not set in Bind(). However, Execute() unconditionally uses bind_msg->param_offset to convert bind parameters to string so that they can be added to the cached query string and it causes segfault because bind_msg->param_offset is a garbage. Also logic bug to calculate bind_msg->param_offset is corrected. Per bug#76. http://www.pgpool.net/mantisbt/view.php?id=76 - Avoid to run out free query cache hash index entry. (Tatsuo Ishii) If hash index entries are run out, pgpool-II cannot reuse old cache entry because pgpool-II always expects there's at least one empty hash index entry. To mitigate the problem, if free hash index entries are run out, look for victim cache block to reuse the hash index entry. Per bug #70. http://www.pgpool.net/mantisbt/view.php?id=70 - Fix inappropriate shared memory allocation size for clock hand. (Tatsuo Ishii) The memory for clock hand was allocated as sizeof(pool_fsmm_clock_hand)) which is 8 bytes long because the variable is declared as: static int *pool_fsmm_clock_hand; This is plain wrong. The memory size actually needed is only 4 bytes, which is sizeof(*pool_fsmm_clock_hand)). In other word, the bug allocated unnecessary 4 bytes, which did nothing bd for the execution of program. But a bug is a bug. Per coverity report "1111476 Wrong sizeof argument" - Fix "show pool_status" always shows memqcache_auto_cache_invalidation as 0. (Tatsuo Ishii) Per bug #80. http://www.pgpool.net/mantisbt/view.php?id=80 - Fix error message in read_password_packet(). (Tatsuo Ishii) - watchdog: Fix to pass big parameter by pointer instead of by value at some function. (Yugo Nagata) - Fix memory leak when SSL is requested. (Tatsuo Ishii) When SSL is requested, pgpool child retries to read start up packet. However it does not free the memory for previous start up packet. Per Coverity report "1111443 Resource". - Fix memory leak when do_query() fails in timestamp rewriting. (Tatsuo Ishii) For this purpose free_select_result() is changed to accept NULL argument. Per Coverity report "1111454, 1111455 Resource leak". - watchdog: Fix to put null character at end of ping result string used in watchdog. (Yugo Nagata) - Fix target node selection logic when "DEALLOCATE portal|statement". (Tatsuo Ishii) When "DEALLOCATE portal|statement" is used and last prepared statement or portal was not found, target node selection map is not set. Probably this is not actually harmful because prepared statement or portal was not found is an error case. The bug was there since day 0. Per Coverity report "1111491 Structurally dead code". - Fix range check bug of MAX_NUM_BACKENDS in corner case. (Tatsuo Ishii) MAX_NUM_BACKENDS is the allowed max number of DB nodes (128, at this point). In reality, probably no one ever tried more than 128 DB nodes and that's the reason why nobody noticed. Per Coverity report "1111429, 1111430 and 1111431 Out-of-bounds write". - Do not set/unset fronted connection info for dead backend. (Tatsuo Ishii) Per bug #82. http://www.pgpool.net/mantisbt/view.php?id=82 - Fix that the script forgets to allow public access to pgpool_catalog. (Tatsuo Ishii) The bug prevents inserting data into user tables if pgpool_catalog is created in native replication mode. The bug was there from day 1. I wonder why nobody noticed until today. Per [pgpool-general-jp: 1229]. http://www.sraoss.jp/pipermail/pgpool-general-jp/2013-November/001228.html - Fix uninitialized variable in error case in pool_do_auth(). (Tatsuo Ishii) If there's no valid backend, pgpool will return garbage pid to frontend in auth phase. Actually because no backend is available, frontend will be disconnected later on. So this is not harmless. Per Coverity report "1127331 Uninitialized scalar variable". - Fix to add node id range check when issue an error message using node id. (Tatsuo Ishii) Per Coverity report #1111433 "Out-of-bounds read". - Fix buffer overrun bug and resource leak bug of parse_copy_data(). (Tatsuo Ishii) Per Coverity report 1111427 "Out-of-bounds write" and 1111453 "Resource leak". - Fix possible segfault in CopyDataRaws(). (Tatsuo Ishii) Coverity pointed out that if pool_get_id() returns an error, VALID_BACKEND will access out of array. Per Coverity report 1111413 "Memory - illegal accesses". - Fix query cache is enabled and protocol version = 2 case. (Tatsuo Ishii) When the protocol version = 2, we assume that session state is "idle". This is not feasible but no way. I recommend to not use query cache with protocol 2. Per Coverity report 1111488 "Uninitialized scalar variable". - Fix strftime() usage in pool_pools(). (Tatsuo Ishii) The buffer is not large enough as expected by the second parameter. This is not harmless because the format string will not produce longer result string than the buffer. Per Coverity report 1111426 "Out-of-bounds access". - Fix resource leak in make_persistent_db_connection. (Tatsuo Ishii) For this purpose, new static function free_persisten_db_connection_memory is added. Per Coverity report #1111468. - Fix a bug that connection check to trusted servers fails when the RTT is very short. (Yugo Nagata) - Fix several small bug fixes detected by Coverity.

This problem is reported in [pgpool-general: 1892] by larisa sabban. [pgpool-general: 1892] Pgpool is unable to connect backend PostgreSQL http://www.sraoss.jp/pipermail/pgpool-general/2013-July/001920.html - Fix "Deploying pgpool-II" section in the document (Tatsuo Ishii) Update descriptions about watchdog use. - Fix a mistake in ssh command of doc/basebackup.sh (Tatsuo Ishii) - Fix a bug in parsing prepared statements with transaction handling in replication mode (Tatsuo Ishii) Parse() automatically starts a transaction for non SELECT query to keep consistency among nodes in replication mode. But this wasn't closed. If wrong query comes in, the transaction goes into an abort state but pgpool does not close the transaction. Thus next query causes error because the transaction is still in abort status. This problem was reported in [pgpool-general: 1877] by Sean Hogan. [pgpool-general: 1877] current transaction is aborted, commands ignored http://www.sraoss.jp/pipermail/pgpool-general/2013-July/001905.html - Fix child process termination with sig abort when memory query cache is enabled (Tatsuo Ishii) This is due to double free bug that occurs when multiple bind/execute messages come after a parse message. When a parse messages comes, query context is created along with temp cache. The pointer to the temp cache is added to the temp cache array when the query executed. Subsequent bind messages uses the same temp cache pointer. This is the source of double free bug when the cache array discarded. This is reported in Bug track #68 by harukat. #68: child process termination with sigabort when memory_cache_enabled = on http://www.pgpool.net/mantisbt/view.php?id=68 - Fix typos of the japanese document (Yugo Nagata) =============================================================================== 3.2.5 (namameboshi) 2013/07/10 * Version 3.2.5 This is a bugfix release against pgpool-II 3.2.4. __________________________________________________________________ * Bug fixes - Add mention about "-D" option to the man page. (Tatsuo Ishii) - Consider timeout waiting for completion of failback request in on line recovery (Tatsuo Ishii) This will prevent the situation that recovery operation continues forever and we cannot even shutdown pgpool-II main process. This could happen especially while executing follow master command. - Fix a bug that %H of follow_master_command is not assigned correctly the new primary node in stream replication mode (Tatsuo Ishii) - Fix wd_create_send_socket() to not execute select() before connect() (Yugo Nagata) How select() works on an unconnected socket is undefined, and differs between platform. On Linux, this returns 2 and it is eventually harmless. However, on Soraris, this returns 0 and it is indistinguishable from time timeout, so watchdog wouldn't work correctly. - Fix error when pgpool_regclass is not installed (Tatsuo Ishii) The query used in pool_has_pgpool_regclass() fails if pgpool_regclass does not exist. The bug was introduced in 3.2.4. See [pgpool-general: 1722] for more details. [pgpool-general: 1722] [PgPool-II 3.2.4] pgpool_regclass now mandatory? http://www.sraoss.jp/pipermail/pgpool-general/2013-May/001749.html - Fix do_query() to not hang when PostgreSQL returns an error (Tatsuo Ishii) The typical symptom is "I see SELECT is keep on running according to pg_stat_activity". To fix this pgpool-II just exits the process and kill the existing connection. This is not gentle but at this point I believe this is the best solution. - Fix possible deadlock during failover with watchdog enabled (Yugo Nagata) This is reported in Bug track #54 by arshu arora #54 pgpool-II semaphore lock problem http://www.pgpool.net/mantisbt/view.php?id=54 - Fix bug with do_query which causes hung in extended protocol (Tatsuo Ishii) This problem could occur when insert lock is enabled and pgpool_catalog.insert_lock exists, See [pgpool-general: 1684] for more details. [pgpool-general: 1684] insert_lock hangs http://www.sraoss.jp/pipermail/pgpool-general/2013-May/001711.html - Fix unnecessary degeneration caused by error on commit (Tatsuo Ishii) In master slave mode, if master gets an error at commit, while other slaves are normal at commit, we don't need to degenerate any backend because it is likely that the "kind mismatch error" was caused by a deferred trigger. - Fix possible failure of query cache invalidation for DML in transaction (Tatsuo Ishii) CREATE TABLE t1(i INTEGER); CREATE TABLE t2(i INTEGER); SELECT * FROM t1; BEGIN; DELETE FROM t2 WHERE i = 0; INSERT INTO t1(i) VALUES(1); COMMIT; SELECT * FROM t1; At commit pgpool tries to delete cache for t2 but fails because there's no oid table entry for t2. Problem is, it fails to check oid table for t1. So cache for t1 remains and the last SELECT incorrectly returns cached data. Fix is, continuing to check oid table entries. This is reported in Bug track #58 by wms #58 query cache invalidation does not fire for multiple DML in transaction http://www.pgpool.net/mantisbt/view.php?id=58 - Fix to register pgpool_regclass in pg_catalog schema (Tatsuo Ishii) This is necessary to deal with clients which restricts schema search path to pg_catalog only. Postgres_fdw is such a client. - Fix a potential crash in pg_md5 command (Muhammad Usama) - Fix a segmentation fault that occurs when on memory query cache enabled and the query is issued in extended query mode and the result is too large (Tatsuo Ishii) This is reported in Bug track #63 by harukat. Analysis and a test case are also provided. #63 Child process was terminated by segmentation fault with memcached http://www.pgpool.net/mantisbt/view.php?id=63 - Fix a segmentation fault of a child process that occurs when a startup packet has no PostgreSQL user information (Yugo Nagata) You can reproduce it by $ psql -p 9999 -U '' If enable_pool_hba is on, a child process terminates by segmentation fault. Otherwise if enable_pool_hba is off, the error message is ERROR: pool_discard_cp: cannot get connection pool for user (null) database (null) In both cases, psql terminates with no message on frontend. In the fixed version, if PostgreSQL user is not specified in startup packet, the message as following is output to both log and frontend. This is the same behavior as PostgreSQL. FATAL: no PostgreSQL user name specified in startup packet - Fix memory allocation logic in extended query processing with on-memory query cache enabled (Tatsuo Ishii) When very long query string (> 1024 bytes) supplied in extended query with bind parameters, it fails to allocate enough memory. - Move ssl_ca_cert and ssl_ca_cert_dir descriptions to the SSL section (Yugo Nagata) - Add ssl_ca_cert and ssl_ca_cert_dir descriptions to the japanese document (Yugo Nagata) - Fix to verify the backend node number in pcp_recovery_node (Yugo Nagata) When an invalid number is used, null value is passed as an arguments of recovery script, and this causes a malfunction. In especially, rsync may delete unrelated files in basebackup scripts. =============================================================================== 3.2.4 (namameboshi) 2013/04/26 * Version 3.2.4 This is a bugfix release against pgpool-II 3.2.3. __________________________________________________________________ * Bug fixes - Fix connect_inet_domain_socket_by_port() to set more appropriate value for timeout parameter of select(2). (Tatsuo Ishii) Some platforms such as Solaris do not allow to specify too large microseconds timeout value (>=1000000). So divide the timeout value to seconds and microseconds. - Fix connect_inet_domain_socket_by_port() to not return as normal when interrupted by alarm. (Tatsuo Ishii) This confuses health checking because connect_inet_domain_socket_by_port() returns usable fd. This makes detecting errors in health checking longer. See the following for more details: [pgpool-general: 1458] health check timeout in pgpool-II-3.2.3 http://www.pgpool.net/pipermail/pgpool-general/2013-March/001482.html - Fix long standing bug with timestamp rewriting code for processing extended protocol. (Tatsuo Ishii) Parse() allocate memory using palloc() while rewriting the parse message. Problem is, the rewritten message was kept in the data which is managed by pool_create_sent_message() etc. The function assumes that all the data is in session context memory. However, palloc() allocates memory in query context of course, and gets freed later on when the query context disappears. And the function tries to free the memory as well, which causes various problems, including segfault and double free. To fix this, memory to store rewritten message is allocated using session context. The bug was there since pgpool-II 3.0 was born. Problem analysis and patch contributed by Naoya Anzai. [pgpoolgenera-jp: 1146]. (in Japanese) http://www.pgpool.net/pipermail/pgpool-general-jp/2013-March/001145.html - Fix bug with md5 auth long user name handling.

(Yugo Nagata) When the primary server is behind from standby server, negative value of delay is calculated and the value is assigned to unsigned variable. It causes a log message informing negative replication delay. And what is worse, it also causes SELECT queries to be sent to the primary in load balance even though there are no replication delay in fact. The problem is reported and analyzed by Saitoh Hidenori in [pgpool-genera-jp: 1145].

(Tatsuo Ishii) Even though pgpool_regclass() exists, if pgpool cannot execute the function, the connection to backend hangs. You can reproduce the problem by just dropping the execute privilege from pgpool_regclass and do some insert in native replication mode. The problem is reported in bugtrack #53. #53 pgpool_regclass hangs all connections Date: 2013-04-04 13:35 Reporter: tmandke http://www.pgpool.net/mantisbt/view.php?id=53 - Fix error message mistakes in detect_postmaster_down_error(). (Tatsuo Ishii) For example, "LOG: detect_stop_postmaster_error: detect_error error" is fixed to "LOG: detect_postmaster_down_error: detect_error error", and so on. - Remove root user check when watchdog is enabled. (Tatsuo Ishii) Per discussion [pgpool-general: 1627] Re: watchdog root requirement. [pgpool-general: 1627] Re: watchdog root requirement. http://www.pgpool.net/pipermail/pgpool-general/2013-April/001654.html - Fix bug with on memory query cache in handling UPDATE/DELETE with table alias. (Tatsuo Ishii) If UPDATE/DELETE is with table alias (UPDATE t1 AS foo...) pgpool thinks the table name is "t1 AS foo" and fails to invalidate query cache. This is caused by _outRangeVar() called from nodeToString() which generates a query string from RangeVar node in raw parse tree. The solution is removing "AS foo" part from the output of the string. Reported in bugtrack #56. #56 UPDATE with alias does not discard cache Date: 2013-04-18 17:33 Reporter: harukat http://www.pgpool.net/mantisbt/view.php?id=56 =============================================================================== 3.2.3 (namameboshi) 2013/02/18 * Version 3.2.3 This is a bug fix release against pgpool-II 3.2.2. Main purpose of this release is to fix fatal problem with pgpool-II 3.2.2's health checking. If all of following conditions are met, pgpool main process disappeared and all client connections to pgpool-II hang forever when failover happens. And the only way to recover from it is, manually killing the pgpool child process and restart pgpool-II. - health checking is enabled - connecting method to PostgreSQL is TCP/IP, not UNIX domain socket(i.e. "backend_hostnameN" is not empty string) __________________________________________________________________ * Bug fixes - Fix connect_inet_domain_socket_by_port() bug introduced in 3.2.2. (Tatsuo Ishii) When non blocking connect() reports EINPROGRESS or EALREADY, it calls select(2) to wait for read or write fd ready. However it mistakenly checks error condition using getsockopt(). It should be called when select() returns > 0, rather than 0. Because of this, connect_inet_domain_socket_by_port() could return succeeded fd even it actually failed. And what is worse, this health_check() mistakenly believes that backend is alive and tries to write to backend socket, which of course fails. This triggers to call notice_backend_error(), which sends SIGUSR1 signal to pgpool main's parent process. This will result in various weird things: for example, if you start pgpool from a shell, the signal kills the shell. If you start pgpool in background, pgpool's parent is the process #1. As long as you started pgpool as non root, it's ok. Even if you start pgpool as root, init just reopens /dev/initctl by receiving SIGUSR1. These all annoying bugs have been there since pgpool was born. The connect_inet_domain_socket_by_port() bug just reveals it. To fix this, I modified notice_backend_error and child_exit() so that it does nothing when called from pgpool main process itself to prevent pgpool from shooting itself in the foot. - Fix to show pool_passwd in "SHOW pool_status". (Yugo Nagata) - Fix a typo at configure's help in configure.in. (Yugo Nagata) =============================================================================== 3.2.2 (namameboshi) 2013/02/08 * Version 3.2.2 This is a bugfix release against pgpool-II 3.2.1. __________________________________________________________________ * Bug fixes - Fix compile errors on FreeBSD. (Tatsuo Ishii) - Fix pgpool does not recognize VIEWs other than in default schema, which is usually "public". (Tatsuo Ishii) This makes pgpool to create caches for such a VIEW's query results, which of course should not be allowed. Problem reported and patch provided by jgentsch in bug id #30. #30 pgpool 3.2.1 - views in schema other than public are caching Reporter: jgentsch Date: 2012-10-19 23:13 http://www.pgpool.net/mantisbt/view.php?id=30 - Fix race condition when using md5 authentication. (Tatsuo Ishii) The file descriptor to pool_passwd is opened in pgpool main and pgpool child inherits it. When concurrent connections try to authenticate md5 method, they call pool_get_passwd and seek the fd and cause random md5 auth failure because underlying fd is shared. Fix is, let individual pgpool child open the file by calling pool_reopen_passwd_file. Problem reported and analyzed by Jason Slagle in pgpool-general:1141. [pgpool-general: 1141] Possible race condition in pool_get_passwd From: Jason Slagle Date: Sun, 28 Oct 2012 01:12:52 -0400 http://www.sraoss.jp/pipermail/pgpool-general/2012-October/001160.html - Clarify load balance condition information in manual. (Tatsuo Ishii) - Fix segfault due to bug with query cache array handling. (Tatsuo Ishii) The cache array is used to keep temporary cache results in a transaction. If there are more than 128 SELECTs in a transaction, the module expands cache_array by using realloc. However it does not record the new pointer returned by realloc. So the module keeps on using the old pointer which is obsoleted. This problem is reported in bug track #31 by jgentsch. #31 pgpool V3_2_STABLE - segfault in pool_memqcache.c:2529 Reporter:jgentsch Date: 2012-10-23 06:25 http://www.pgpool.net/mantisbt/view.php?id=31 - Fix hung up while repeating pcp_attach_node and pcp_detach_node (Tatsuo Ishii) When node status is changed by pcp_attach_node and pcp_detach_node, failover() sends SIGUSR1 to pcp_child process expecting it exits to refresh node status. In this situation lots of pgpool children exit and produce SIGCHLD as well. The SIGCHLD handler reaper() tries catch all SIGCHLD but sometimes it fails depending on the system load and timing. If SIGCHLD produced by pcp child is not caught, the process becomes zombie and never restarted. This problem is reported in bug track #32 (by oleg_myrk) etc. #32 PGPool hangs on pcp_attach/detach Reporter: oleg_myrk Date: 2012-10-24 00:01 http://www.pgpool.net/mantisbt/view.php?id=32 - Fix pool_send_severity_message() not to use uninitialized memory. (Tatsuo Ishii) It cause a segmentation fault. Reported in Bug #33's attached valgrind output by dudee. #33 pgpool-II 3.2.1 segfault Reporter: dudee Date: 2012-10-30 19:16 http://www.pgpool.net/mantisbt/view.php?id=33 - Fix bug with query cache returning incorrect data in some cases when a persistent table and temp table have same name. (Tatsuo Ishii) Here is a sequence to trigger the bug: 1) CREATE TABLE t1(i int); -- create a persistent table 2) INSERT INTO t1 VALUES(1); 3) SELECT * FROM t1; -- query cache entry created 4) CREATE TEMP TABLE t1(i int); -- create a temp table 5) SELECT * FROM t1; -- query cache entry mistakenly created! Problem is #3 creates relcache entry for t1, and #5 incorrectly uses it and believes that temp table t1 is not a temp table. - Add a description about "-f" to help message. (Tatsuo Ishii) - Fix reaper() not to exit wait3() loop when catches pcp or worker child exit event. (Tatsuo Ishii) Otherwise reaper() mistakenly ignore some process exit event and make a risk of creating zombie process and forgetting to create new process. Problem reported and fix suggested by Goto in [pgpool-general-jp: 1123]. http://www.sraoss.jp/pipermail/pgpool-general-jp/2012-November/001122.html (in Japanese) - Fix a typo of configure help message. (Yugo Nagata) - Add wd_hostname to pool_process_reporting.c. (Yugo Nagata) Otherwise, wd_hostname is not contained in results of SHOW pool_status and cp_pool_status. - Fix connect_inet_domain_socket_by_port() to not error out when connect(2) returns EISCONN (Socket is already connected) error. (Tatsuo Ishii) This could happen with non blocking socket and should be treated as normal. Per bug track #29 (by spork) and pgpool-general 1218 (by Mikola Rose). #29 pgpool 3.2.1 cannot connect to db hosts Reporter: spork Date: 2012-10-18 15:03 http://www.pgpool.net/mantisbt/view.php?id=29 [pgpool-general: 1218] pgpool 3.2.1 - Health check failing to connect From: Mikola Rose Date: Tue, 4 Dec 2012 20:21:55 +0000 http://www.sraoss.jp/pipermail/pgpool-general/2012-December/001237.html - Fix health_check() to check the health check timer before retrying with template1 database. (Tatsuo Ishii) Without this, the retry with node 0 always fails because health check timer may be already expired. - Fix pool_search_relcache() to use MASTER or MASTER_NODE_ID macro, rather than REAL_MASTER_NODE_ID. (Tatsuo Ishii) In case node 0 fail back in streaming replication mode, pgpool does not restart child process. So REAL_MASTER_NODE_ID looks for node 0 con info, which is not present until new connection to backend made. Thus referring to node con info results in segfault. MASTER or MASTER_NODE_ID are safe in this situation because they look at cached former master node id. - Fix long standing bug "portal not found" error when replication delay is too much in streaming replication mode. (Tatsuo Ishii) The bug had been there since the delay threshold was introduced. We changed destination DB node if delay threshold exceeds in bind, describe and execute. However, if parse sends to different node, bind, describe or execute will fail because no parsed statement or portal exists. Solution is, not to send to different parse node even if delay threshold is too much. - Fix pg_md5 to output "\n" after user inputs password. (Yugo Nagata) - Fix to print error message when the port number for watchdog is already used. (Yugo Nagata) This issue was reported by Will Ferguson in [pgpool-general: 1167]. [pgpool-general: 1167] Re: Watchdog error - wd_init: delegate_IP already exists From: Will Ferguson Date: Tue, 6 Nov 2012 13:03:36 +0000 http://www.sraoss.jp/pipermail/pgpool-general/2012-November/001186.html - Fix child_exit() to not call send_frontend_exits() if there's no connection pool. (Tatsuo Ishii) Otherwise, it segfaults because send_frontend_exits() refers to objects pointed to by pool_connection_pool. Per bug track #44 by tuomas. #44 pgpool went haywire after slave shutdown triggering master failover Reporter: tuomas Date: 2012-12-11 00:33 http://www.pgpool.net/mantisbt/view.php?id=44 - Fix bug that only tables in white_memqcache_table_list was cached when black_memqcache_table_list has any tables. (Yugo Nagata) - Fix read_startup_packet() to reset alarm and free StartupPacket when pool_read() returns 0 which means incorrect packet length. (Nozomi Anzai) Previously, authentication timeout occurs when connected by a program monitoring the pgpool port.It is reported in bug track #35. #35 Authentication is timeout Reporter: tuomas Date: 2012-11-20 11:54 http://www.pgpool.net/mantisbt/view.php?id=35 - Fix long standing bug with pool_open(). (Tatsuo Ishii) It initializes wrong buffer pointer. Actually this is harmless because the pointer is initialized by prior memset() call, though. - Log that failover is avoided because "fail_over_on_backend_error" is turned off. (Tatsuo Ishii) - Fix LISTEN/NOTIFY handling bugs. (Tatsuo Ishii) 1) In streaming replication mode: Session 1: LISTEN aaa; Session 2: NOTIFY aaa; Session 1: LISTEN aaa; --- hangs (If LISTEN and NOTIFY are issued in a same session, it works fine.) We assume that packets come from all nodes. However in streaming replication mode, notification message only comes from primary node and we should avoid reading from standby nodes. 2) In streaming replication mode: If primary node is not node 0, it hangs like #1 even if fix applies. This is because MASTER_NODE_ID macro (actually pool_virtual_master_db_node_id()) always returns REAL_MASTER_NODE_ID, which is node 0 (if it is alive). The function should return PRIMARY_NODE_ID in master/slave mode. 3) In replication mode, LISTEN/NOTIFY simply does not work. In the mode, NOTIFY is sent to all backends. However the order of arrival of 'Notification response' is not necessarily the master first and then slaves. So if it arrives slave first, we should try to read from master, rather than just discard it. Fixed in pool_process_query(). 4) In replication mode, if LISTEN and NOTIFY are issued in a same session, the session is disconnected because do_command() may receive other than 'N', 'E', 'S' and 'C'. The solution is, put 'A' packet on a stack and pop out when it is convenient. For this purpose, new functions pool_push(), pool_pop() and pool_stacklen() are added. This problem is reported in but grack #45 by rpashin. #45 LISTEN/NOTIFY doesn't work if cluster contains more then 1 node in streaming replication mode Reporter: rpashin Date: 2012-12-12 00:09 http://www.pgpool.net/mantisbt/view.php?id=45 Considering the size of the patch, I do not back patch to 3.1 or before(so far, we have not heard any complaints on 3.1 or before). - Fix connect_inet_domain_socket_by_port() to call select(2) rather than error out when connect(2) returns EINPROGESS or EALREADY error. (Tatsuo Ishii) When using non-blocking socket, despite the errors like "Connection timed out", actually connection has been established. To solve the problem we should use select(2) to wait for connection establishing when connect(2) reports EINPROGRESS or EALREADY, instead of doing a retry tight loop. This problem is reported in bug track #46 by mcousin. #46 Watchdog failing to connect sometimes Reporter: mcousin Date: 2012-12-15 01:01 http://www.pgpool.net/mantisbt/view.php?id=46 - Add caution to increase num_init_children if watchdog enabled in manual.

Reporter: chads Date: 2013-01-16 05:44 http://www.pgpool.net/mantisbt/view.php?id=48 - Avoid split-brain situation reported in [pgpool-general: 1046] (Yugo Nagata) After all backend nodes are detached from pgpools and then some backend node are attached to these, multiple active pgpools could exist simultaneously, that is to say, split-brain situation occurs. In this fix, when once all backend DB nodes are detached from pgpool, the pgpool stays DOWN status until this is restarted. The pgpool in DOWN status cannot escalate to active (delegate IP holder), so split-brain situation is avoided. [pgpool-general: 1046] watchdog enabled delegate_IP on multiple nodes simultaneously From: Lonni J Friedman Date: Wed, 26 Sep 2012 09:05:09 -0700 http://www.sraoss.jp/pipermail/pgpool-general/2012-September/001064.html - Avoid a possible hang during the active pgpool exits. (Yugo Nagata) When exiting, the active pgpool brings down the virtual IP and then sends a packet to other pgpools. However, the packet sometimes is sent before the virtual IP is brought down completely. In this case the packet sender is set to this IP. When the IP is brought down before other pgpools respond, the active pgpool can not receive the response, and hang up. In this fix, the active pgpool confirms that the virtual IP is brought down before sending the packet. - Modify descriptions of restrictions on watchdog. (Yugo Nagata) - Modify pgpool.conf.sample* and documents to correct information of whether a certain parameter change requires restart. (Yugo Nagata) - Add pool_passwd option to pgpool.conf.sample*, pool_process_reporting.c, and documents. (Yugo Nagata) Otherwise, wd_hostname is not contained in results of SHOW pool_status and pcp_pool_status. =============================================================================== 3.2.1 (namameboshi) 2012/10/12 * Version 3.2.1 This is a bugfix release against pgpool-II 3.2.0. __________________________________________________________________ * Bug fixes - Fix send_cached_messages(). (Tatsuo Ishii) Before it had 8192 bytes fix length buffer for each row data and if data exceeded 8192 bytes, it just crashed. To fix this, eliminate copying raw data which is passed as an argument to buffer and pass the pointer to send_message. - Fix that extended queries failed due to query cache. (Nozomi Anzai) - Fix read_startup_packet(). (Tatsuo Ishii) If packet length is lower than 0, it should have returned immediately. Otherwise it would cause memory allocation error later on. per pgpool-general:886. Also add canceling alarm. [pgpool-general: 886] read_startup_packet: out of memory From: Lonni J Friedman Date: Wed, 8 Aug 2012 10:18:15 -0700 http://www.sraoss.jp/pipermail/pgpool-general/2012-August/000896.html - Fix too watchdog process's aggressively kill other processes when pgpool shuts down. (Tatsuo Ishii) watchdog process calls kill(0,SIG) to kill all processes related to watchdog. Unfortunately this will kill not only watchdog related processes but parent pgpool and even httpd in case when pgpool was invoked from pgpoolAdmin because they are in the same process group. So for now, fix is removing call to the kill() and setpgid() because setpgid() does nothing useful. In the future, we should call setsid() to establish new process group in any case. - Fix query cache to regist such queries that start with "-- comment" or have comments more than one. (Nozomi Anzai) - Fix query cache to ignore multi statement. (Nozomi Anzai) In previous, queries like "SELECT 1;UPDATE..." were cached, too, but it was wrong. - Add a watchdog restriction to documents. (Yugo Nagata) - Add NOTICE message handling to s_do_auth(). (Tatsuo Ishii) Without this, health check responses false alarm and causes failover. per bug track: #25 s_do_auth doesn't handle NoticeResponse (N) message Date: 2012-08-28 03:57 Reporter: singh.gurjeet Date: http://www.pgpool.net/mantisbt/view.php?id=25 - Remove unnecessary/confusing debug log from s_do_auth().(Tatsuo Ishii) - Fix buffer overrun in Execute when memory cache enabled. (Tatsuo Ishii) If one of bind parameter < 0, it was possible to produce more than 2 byte string for "%02X" due to sign extension. Also use snprintf, rather than sprintf to prevent from possible buffer overrun in the future. - Fix long standing memory leak bug with free_select_result() since pgpool-II 2.3 was born in December 2009. (Tatsuo Ishii) Actually this bug only appears when operated in replication mode (triggered by timestamp rewriting process by coincidence). Per bug track #24: #24 Severe memory leak in an OLTP environment Date: 2012-08-28 03:43 Reporter: singh.gurjeet Date: http://www.pgpool.net/mantisbt/view.php?id=24 - Fix typo in cache_reporting(). (Tatsuo Ishii) - Fix infinite loop in SSL mode. (Tatsuo Ishii) When there's pending data in SSL layer of frontend, pool_process_query() checks pending data in backend. If there's non, it loops again and checks frontend/backend receive buffer by using is_cache_empty(). Unfortunately it first checks pending data in SSL layer of frontend, thus goes to backend data and checks again (infinite loop). The solution is, if there's pending data in SSL layer of frontend and query is not in progress, call ProcessFrontendResponse() to process new request from frontend. - Fix is_system_catalog() to use pgpool_regclass if available. (Tatsuo Ishii) - Fix memory leak in pool_get_insert_table_name(). (Tatsuo Ishii) If session context's memory contex is used for nodeToString(), memory is not freed until session ends. See bug track #24 for more details. #24 Severe memory leak in an OLTP environment Date: 2012-08-28 03:43 Reporter: singh.gurjeet http://www.pgpool.net/mantisbt/view.php?id=24 - Use fcntl(2) rather than flock(2) to lock oid map files. (Tatsuo Ishii) flock(2) is not portable and cannot be used on Solaris. Patch contributed by Ibrar Ahmed. - Fix oversight of get_next_master_node() when operated in raw mode. (Tatsuo Ishii) If master node goes down, it always returned master node id 0. See [pgpool-general: 1039] for more details. [pgpool-general: 1039] Raw failover not working as expected on pgpool-II v3.2.0 From: Quentin White Date: Tue, 25 Sep 2012 07:45:34 +0000 http://www.sraoss.jp/pipermail/pgpool-general/2012-September/001057.html - Fix segfault of do_query(). (Tatsuo Ishii) When memqcache enabled and extended protocol is used, do_query() accesses system catalog and use pool_read2(). Unfortunately parse message packet is given to Parse() and the packet contents is on pool_read2's buffer. Thus do_query could break the packet contents, and it leads to segfault. Solution is, allocate memory and copies the packet contents and pass to Parse(). Note that query context holds query string, which is in the packet as well. So we need to copy it and save the pointer in the query context. We think the problem is not only with Parse() but with other protocol modules. So this fix is not Parse() only, rather for other modules. For this purpose ProcessFrontendResponse() is changed. See bugtrack in detail. #21 pgpool-II 3.2.0 cannot execute sql through jdbc Date: 2012-08-17 16:31 Reporter: elisechiang http://www.pgpool.net/mantisbt/view.php?id=21 - Fix to set unix domain socket path for pgpool PCP communication before setting up signal handlers. (Yugo Nagata) Previously, unlink of the socket in exiting process was failed because the path of the socket was not set. Patch contributed by Gilles Darold [pgpool-hackers: 131] Found bug with watchdog resulting in pgpool segmentation fault From: Gilles Darold Date: Thu, 13 Sep 2012 18:54:42 +0200 http://www.sraoss.jp/pipermail/pgpool-hackers/2012-September/000130.html - Fix to output the message when, in watchdog, ifup/down or arping command does not exist. (Yugo Nagata) - Fix long standing problem with do_query(). (Tatsuo Ishii) When 1) extended protocol used and 2)unnamed portal is used and 3) no explicit transaction is used, user's unnamed portal is removed by Sync message. This is because Sync message closes transaction and unnamed portal is removed. This leads to "portal "" does not exist" error. Fix is, use "Flush" message instead of Sync. Main difference between using Sync and Flush is, Flush does not return Ready for Query message. So do_query() does not return until all expected responses are returned. It seems the order of messages returned from backend is random, and do_query () manages it by using state bits. =============================================================================== 3.2.0 (namameboshi) 2012/08/03 * Version 3.2.0 This is the first version of pgpool-II 3.2 series. That is, a "major version up" from 3.1 series. __________________________________________________________________ * Incompatible changes - The new query cache "On memory query cache" took the place of the old one. - Now the parameter "enable_query_cache" is deleted. __________________________________________________________________ * New features ** Memory based query cache Original author is Masanori Yamazaki, improved by Development Group. (Tatsuo Ishii, Nozomi Anzai, Yugo Nagata) Overview: On memory query cache is faster because cache storage is on memory. Moreover you don't need to restart pgpool-II when the cache is outdated because the underlying table gets updated. On memory cache saves pair of SELECT statements (with its Bind parameters if the SELECT is an extended query). If the same SELECTs comes in, it returns the value from cache. Since no SQL parsing nor access to PostgreSQL are involved, it's extremely fast. On the other hand, it might be slower than the normal path because it adds some overhead to store cache. Moreover when a table is updated, pgpool automatically deletes all the caches related to the table. So the performance will be degraded by a system with a lot of updates. If the cache_hit_ratio is lower than 70%, you might want to disable onl memory cache. Choosing cache storage: You can choose a cache storage: shared memory or memcached (you can't use the both). Query cache with shared memory is fast and easy because you don't have to install and config memcached, but restricted the max size of cache by the one of shared memory. Query cache with memcached needs a overhead to access network, but you can set the size as you like. Restrictions: - On memory query cache deletes the all cache of an updated table automatically with monitoring if the executed query is UPDATE, INSERT, ALTER TABLE and so on. But pgpool-II isn't able to recognize implicit updates due to triggers, foreign keys and DROP TABLE CASCADE. You can avoid this problem with memqcache_expire by which pgpool deletes old cache in a fixed time automatically, or with black_memqcache_table_list by which pgpool's memory cache flow ignores the tables. - If you want to use multiple instances of pgpool-II with online memory cache which uses shared memory, it could happen that one pgpool deletes cache, and the other one doesn't do it thus finds old cached result when a table gets updated. Memcached is the better cache storage in this case. New parameters: - Add parameters for on memory query cache as follows: memory_cache_enabled, memqcache_method, memqcache_expire, memqcache_maxcache, memqcache_oiddir. (Tatsuo Ishii) - Add parameters about shared memory for on memory query cache as follows: memqcache_total_size, memqcache_max_num_cache, memqcache_cache_block_size. (Tatsuo Ishii) - Add parameters about memcached for on memory query cache as follows: memqcache_memcached_host, memqcache_memcached_port. (Tatsuo Ishii) - Add parameters about relation cache for on memory query cache as follows: relcache_expire, relcache_size. (Tatsuo Ishii) - Add a parameter "check_temp_table" to check if the SELECTed table is temp table. (Tatsuo Ishii) - Add the parameters of white_memqcache_table_list, black_memqcache_table_list that check if the SELECTed tables, temp tables and views are to be cached or not. (Nozomi Anzai) - Add a parameter "memqcache_auto_cache_invalidation" of the flag if query cache is triggered by corresponding DDL/DML/DCL (and memqcache_expire). (Yugo Nagata) New commands: - Add "SHOW pool cache" which shows hit ratio of query cache and the status of cache storage. - Add "--with-memcached" option to configure. (Nozomi Anzai) - Add "-C, --clear-oidmaps" option to "pgpool" command. (Nozomi Anzai) If pgpool with memcached starts / restarts with -C option, discard oid maps, if not, it can reuse old oid maps and query caches. ** Watchdog The author is Atsushi Mitani, tested by Yugo Nagata. Overview: "Watchdog" is a sub process of pgpool-II aiming for adding high availability feature to it. Features added by watchdog include: - Life checking of pgpool service Watchdog monitors responses of pgpool service rather than process. It sends queries to PostgreSQL via pgpool which is being monitored by watchdog and watchdog checks the response. Also watchdog monitors connections to up stream servers (application servers etc.) from the pgpool. The connection between the up stream servers and the pgpool is monitored as service of pgpool. - Mutual monitoring of watchdog processes Watchdog processes exchange information on the monitored servers to keep the information up to date, and to allow watchdog processes to mutually monitor each other. - Changing active/standby state in case of certain faults detected When a fault is detected in the pgpool service, watchdog notifies the other watchdogs of it. Watchdogs decide the new active pgpool if previous active pgpool is broken by voting and change active/standby state. - Automatic virtual IP address assigning synchronous to server switching When a standby pgpool server promotes to active, the new active server brings up virtual IP interface. Meanwhile, the previous active server brings down the virtual IP interface. This enables the active pgpool to work using the same IP address even when servers is switched over. - Automatic registration of a server as standby in recovery When broken server recovers or new server is attached, the watchdog process notifies the other watchdog process along with information of the new server, and the watchdog process receives information on the active server and other servers. Then, the attached server is registered as standby. New parameters: - Add a parameter to enable watchdog: use_watchdog. (Atsushi Mitani) - Add the parameters about life checking of pgpool service as follows: wd_interval,other_pgpool_port wd_life_point, wd_lifecheck_query, other_pgpool_hostname, other_pgpool_port. (Atsushi Mitani) - Add the parameters about up to stream connection (e.g. to application servers) as follows: trusted_servers, ping_path. (Atsushi Mitani) - Add the parameters about mutual monitoring of watchdog processes as follows: wd_hostname, wd_port, other_wd_port. (Atsushi Mitani) - Add the parameters about virtual IP as follows: ifconfig_path, if_up_cmd, if_down_cmd, arping_path, arping_cmd. (Atsushi Mitani) __________________________________________________________________ * Enhancements - Retry if health check failed rather than immediately do failover. For this purpose new directives "health_check_max_retries" and "health_check_retry_delay" were added. (Tatsuo Ishii) Patch contributed by Matt Solnit. Subject: [Pgpool-hackers] Health check retries (patch) From: Matt Solnit Date: Fri, 18 Nov 2011 16:28:44 -0500 - Log client IP and port number when pgpool failed to parse given query. (Tatsuo) This is useful to identify which client gives wrong query without enabling log_connections, which produces too many log entries on busy web systems. - Refactor pool_process_query(). (Tatsuo Ishii) Deal with the case when: 1) query not in progress 2) other than master node has pending data. It is reported that pgpool goes into infinite loop in this case. [pgpool-general: 43] Re: [Pgpool-general] seemingly hung pgpool process consuming 100% CPU http://www.pgpool.net/pipermail/pgpool-general/2011-December/000042.html - Add "role" which represents "primary" or "standby" iin streaming replication mode for example to "SHOW pool_nodes" command.(Tatsuo Ishii) - Add params to the result of "SHOW pool_status": backend_data_directory, ssl_ca_cert, ssl_ca_cert_dir, and sort by orders in pgpool.conf. (Anzai) - Commentout params about system db from pgpool.conf.sample-*. (Nozomi Anzai) - Add new parameter to failover/failback/followmaster command. (Tatsuo Ishii) %r: new master port number %R: new master database cluster path - Allow to reload to recognize md5 password change. (Tatsuo Ishii) Before, the only way to recognize md5 password change was restarting pgpool-II. Patch contributed by Gurjeet Singh. - Remove unused parameter "query" from is_set_transaction_serializable(). (Tatsuo Ishii) - Fix on memory query cache section's comments in pgpool.com in the way which other sections employ. (Tatsuo Ishii) - Add missing health_check_max_retries and health_check_retry_delay directives to pgpool.conf.sample-master-slave, pgpool.conf.sample-replication pgpool.conf.sample-stream. (Tatsuo Ishii) - Fix pool_ssl_write. It seems someone forgot to do retrying when SSL returns SSL_ERROR_WANT_READ or SSL_ERROR_WANT_WRITE. Per [pgpool-general: 797] [pgpool-general: 797] Re: Problem with pgpool when using SSL, for client/pgpool communication http://www.sraoss.jp/pipermail/pgpool-general/2012-July/000807.html - Improve the design of manuals. (Nozomi Anzai) __________________________________________________________________ * Bug Fix - Fix memory leak in Raw mode.(Tatsuo Ishii) - Fix failover/failback in Raw mode. (Tatsuo Ishii) - Simply does not failover if target node is not master. - Fail to select master node if the node is in CON_UP. - Allow health check retry while connect(). (Tatsuo Ishii) It is reported that connect() blocks sigalarm under some conditions, for example: When system is configured for security reasons not to return destination host unreachable messages ([pgpool-general: 131]) Part of changes are contributed by Stevo Slavic. [pgpool-general: 131] Healthcheck timeout not always respected http://www.pgpool.net/pipermail/pgpool-general/2012-January/000131.html - Fix pool_send_and_wait() to send or not to send COMMIT / ABORT depending on the transaction state on each node. (Tatsuo Ishii) It is possible that only primary is in an explicit transaction but standby is not in it if multi statement query has been sent. Per bug report [pgpool-general-jp: 1049]. - Fix load balance in Solaris. (Tatsuo Ishii) Problem is, random() in using random() in Solaris results in strange load balancing calculation. Use srand()/rand() instead although they produce lesser quality random Problem reported at [pgpool-general: 396]. [pgpool-general: 396] strange load balancing issue in Solaris http://www.pgpool.net/pipermail/pgpool-general/2012-April/000397.html - Fix segfault of pcp_systemdb_info not in parallel mode. (Nozomi Anzai) - Fix "unnamed prepared statement does not exist" error. (Tatsuo Ishii) This is caused by pgpool's internal query, which breaks client's unnamed statements. To fix this, if extended query is used, named statement/portal for internal are used for internal query. - Fix hangup when query conflict occurs in Hot-Standby mode. (Yugo Nagata) Query example to reproduce: (S1) BEGIN; (S1) SELECT * FROM t; (S2) DELETE FROM t; (S2) VACUUM t; - Fix pool_process_query() bug reported in [pgpool-general: 672]. (Tatsuo Ishii) This is caused by the function waits for primary node which does not have pending data, while standbys have pending data. [pgpool-general: 672] Transaction never finishes http://www.pgpool.net/pipermail/pgpool-general/2012-June/000676.html - Fix wait_for_query_response() not to send param status to frontend if frontend is NULL. (Tatsuo Ishii) This could happen while processing reset_query_list and occur crash. - Fix bug with treatment of BEGIN TRANSACTION in master/slave mode. (Tatsuo Ishii) Original complain is [pgpool-general: 714]. From 3.1, pgpool-II sends BEGIN.. to all DB nodes. Of course we cannot send BEGIN TRANSACTION READ WRITE to standby nodes. Problem is, we did not check BEGIN WORK ISOLATION LEVEL SERIALIZABLE; and sent to standby nodes. Of course this is wrong, since it's not allowed to run transactions in serializable mode on standby nodes. So added check for BEGIN WORK ISOLATION LEVEL SERIALIZABLE case. [pgpool-general: 714] Load Balancing / Streaming Replication / Isolation Level serializable http://www.pgpool.net/pipermail/pgpool-general/2012-July/000719.html - Fix send_to_where() to send the query to only primary if the it is like SET TRANSACTION ISOLATION LEVELSERIALIZABLE etc. (Tatsuo Ishii) Case in streaming replication mode. Previously, it was sent to not only primary but also to standby and of course this causes an error. Similar SQLs are: SET SESSION CHARACTERISTICS AS TRANSACTION ISOLATION LEVEL SERIALIZABLE or SET transaction_isolation TO 'serializable' SET default_transaction_isolation TO 'serializable' Original complain is [pgpool-general: 715]. [pgpool-general: 715] Re: Load Balancing / Streaming Replication / Isolation Level serializable http://www.pgpool.net/pipermail/pgpool-general/2012-July/000720.html - Prevent errors even if memcached is not available with on memory query cache enabled and cache storage is memcached. (Tatsuo Ishii) This is mainly achieved by modifying pool_fetch_cache to pretend "cache not found" if memcached_get returns error other than MEMCACHED_NOTFOUND. Also we set pool_config->memory_cache_enabled to 0 to prevent future errors by accessing memcached. - Run rerun libtoolize with --copy and --force option. (Tatsuo Ishii) This should prevent build problems in different environment. Following commands were executed: libtoolize --copy --force aclocal autoheader automake -a autoconf - Fix pool_ssl_read. (Tatsuo Ishii) When SSL_read returns unknown error, treat as if EOF detected and returns 0 to caller (pool_read). This is same as libpq's behavior. Also this will avoid unwanted failover in pool_read. pool_read triggers failover if underlying I/O functions, read(2) or pool_ssl_read returns -1. - Fix pool_process_query. (Tatsuo Ishii) When other than primary sends packet, pgpool tries to terminate session gracefully and hung because now ssl_read returns EOF, rather than error and triggers failover. For example [pgpool-general: 766] reported this: 2012-07-17 00:11:03 NZST [15692]: [257-1] ERROR: canceling statement due to conflict with recovery 2012-07-17 00:11:03 NZST [15692]: [258-1] DETAIL: User query might have needed to see row versions that must be removed. 2012-07-17 00:11:03 NZST [15692]: [259-1] STATEMENT: 2012-07-17 00:11:03 NZST [15696]: [366-1] FATAL: terminating connection due to conflict with recovery 2012-07-17 00:11:03 NZST [15696]: [367-1] DETAIL: User query might have needed to see row versions that must be removed. In this case pool_process_query should return POOL_ERROR, rather than POOL_END. [pgpool-general: 766] Re: pgpool dropping backends too much http://www.pgpool.net/pipermail/pgpool-general/2012-July/000774.html - If frontend terminates while reading large number of query results from backend, pgpool continues to read from backend and write to frontend until all query results consumed. (Tatsuo Ishii) This will take very long time if query results is huge. To finish pgpool session as soon as possible, modify pool_flush_it to returns error if fail to write to frontend when operated in other than replication mode. In replication mode, we need to keep the previous behavior to save consistency among backends). Also fix SimpleForwardToFrontend to return pool_write_and_flush error status. Before it was ignored. =============================================================================== 3.1 Series (2011/09/08 - ) =============================================================================== 3.1.20 (hatsuiboshi) 2016/08/31 * Version 3.1.20 This is a bugfix release against pgpool-II 3.1.19. __________________________________________________________________ * Bug fixes - Fix buffer over run problem in "show pool_nodes". (Tatsuo Ishii) While processing "show pool_nodes", the buffer for hostname was too short. It should be same size as the buffer used for pgpool.conf. Problem reported by a twitter user who is using pgpool on AWS (which could have very long hostname). - Fix usage of wait(2) in pgpool main process. (Tatsuo Ishii) The usage of wait(2) in pgpool main could cause infinite wait in the system call. Solution is, to use waitpid(2) instead of wait(2). - Fix "kind mismatch" error message in pgpool. (Muhammad Usama) Many of "kind mismatch..." errors are caused by notice/warning messages produced by one or more of the DB nodes. In this case now Pgpool-II forwards the messages to frontend, rather than throwing the "kind mismatch..." error. This would reduce the chance of "kind mismatch..." errors. See [pgpool-hackers: 1501] for more details. - Replace "MAJOR" macro to prevent occasional failure. (Tatsuo Ishii) The macro calls pool_virtual_master_db_node_id() and then access backend->slots[id]->con using the node id returned. In rare cases, it could point to 0 (in case when the DB node is not connected), which gives access to con->major, then it causes a segfault. See bug 225 for related info. - doc : fix Japanese document typo. (Bo Peng) - Fixing a typo in the log message. (Muhammad Usama) - doc : Add comment to the document about connection_cache. (Tatsuo Ishii) =============================================================================== 3.1.19 (hatsuiboshi) 2016/06/17 * Version 3.1.19 This is a bugfix release against pgpool-II 3.1.18. __________________________________________________________________ * Bug fixes - Fix is_set_transaction_serializable() when SET default_transaction_isolation TO 'serializable'. (Bo Peng) SET default_transaction_isolation TO 'serializable' is sent to not only primary but also to standby server in streaming replication mode, and this causes an error. Fix is, in streaming replication mode, SET default_transaction_isolation TO 'serializable' is sent only to the primary server. See bug 191 for related info. - Fix Chinese documentation bug about raw mode (Yugo Nagata, Bo Peng) Connection pool is available in raw mode. - Fix confusing comments in pgpool.conf (Tatsuo Ishii) - Permit pgpool to support multiple SSL cipher protocols (Muhammad Usama) Currently TLSv1_method() is used to initialize the SSL context, that puts an unnecessary limitation to allow only TLSv1 protocol for SSL communication. While postgreSQL supports other ciphers protocols as well. The commit changes the above and initializes the SSLSession using the SSLv23_method() (same is also used by PostgreSQL). Because it can negotiate the use of the highest mutually supported protocol version and remove the limitation of one specific protocol version. - If statement timeout is enabled on backend and do_query() sends a (Tatsuo Ishii) query to primary node, and all of following user queries are sent to standby, it is possible that the next command, for example END, could cause a statement timeout error on the primary, and a kind mismatch error on pgpool-II is raised. This fix tries to mitigate the problem by sending sync message instead of flush message in do_query(), expecting that the sync message reset the statement timeout timer if we are in an explicit transaction. We cannot use this technique for implicit transaction case, because the sync message removes the unnamed portal if there's any. Plus, pg_stat_statement will no longer show the query issued by do_query() as "running". See bug 194 for related info. - Deal with the case when the primary is not node 0 in streaming replication mode. (Tatsuo Ishii) http://www.pgpool.net/mantisbt/view.php?id=194#c837 reported that if primary is not node 0, then statement timeout could occur even after bug194-3.3.diff was applied. After some investigation, it appeared that MASTER macro could return other than primary or load balance node, which was not supposed to happen, thus do_query() sends queries to wrong node (this is not clear from the report but I confirmed it in my investigation). pool_virtual_master_db_node_id(), which is called in MASTER macro returns query_context->virtual_master_node_id if query context exists. This could return wrong node if the variable has not been set yet. To fix this, the function is modified: if the variable is not either load balance node or primary node, the primary node id is returned. - change the Makefile under the directory src/sql/, that is proposed (Bo Peng) by [pgpool-hackers: 1611] - Fix a possible hang during health checking (Yugo Nagata) Health checking was hang when any data wasn't sent from backend after connect(2) succeeded. To fix this, pool_check_fd() returns 1 when select(2) exits with EINTR due to SIGALRM while health checking is performed. Reported and patch provided by harukat and some modification by Yugo. Per bug #204. backported from 3.4 or later; https://git.postgresql.org/gitweb/?p=pgpool2.git;a=commitdiff;h=ed9f2900f1b611f5cfd52e8f758c3616861e60c0 - Fix bug with load balance node id info on shmem (Tatsuo Ishii) There are few places where the load balance node was mistakenly put on wrong place. It should be placed on: ConnectionInfo *con_info[child id, connection pool_id, backend id].load_balancing_node]. In fact it was placed on: *con_info[child id, connection pool_id, 0].load_balancing_node]. As long as the backend id in question is 0, it is ok. However while testing pgpool-II 3.6's enhancement regarding failover, if primary node is 1 (which is the load balance node) and standby is 0, a client connecting to node 1 is disconnected when failover happens on node 0. This is unexpected and the bug was revealed. It seems the bug was there since long time ago but it had not found until today by the reason above. =============================================================================== 3.1.18 (hatsuiboshi) 2016/04/26 * Version 3.1.18 This is a bugfix release against pgpool-II 3.1.17. __________________________________________________________________ * Bug fixes - Removing the limit on the maximum number of items in the black_function_list and white_function_list lists. (Muhammad Usama) extract_string_tokens in pool_config uses the fixed size malloc on the array to hold the black_function_list/white_function_list items. This imposes a limit of maximum items in these lists. The fix is to use realloc to increase the array size when it gets full. - Redirect all user queries to primary server (Tatsuo Ishii) Up to now some user queries are sent to other than the primary server even if load_balance_mode = off. This commit changes the behavior: if load_balance_mode = off in streaming replication mode, now all the user queries are sent to the primary server only. Per bug #189. - Change the PID length of pcp_proc_count command result to 6 characters long (Bo Peng) If the pgpool process ID are over 5 characters, the 6th character of each process ID will be removed. This commit changes the process ID length of pcp_proc_count command result to 6 characters long. Per bug #188. =============================================================================== 3.1.17 (hatsuiboshi) 2016/04/04 * Version 3.1.17 This is a bugfix release against pgpool-II 3.1.16. __________________________________________________________________ * Bug fixes - doc: Change description of backend_flag (Tatsuo Ishii) It is pointed out that restarting pgpool-II is not necessary. Per [pgpool-general-jp: 1394]. - doc: Fix installation procedure. (Tatsuo Ishii) With PostgreSQL 9.4 or later, installing pgpool_regclass is not needed. - Fix to validate the PCP packet length (Muhammad Usama) Without the validation check, a malformed PCP packet can crash the PCP child and/or can run the server out of memory by sending the packet with a very large data size. - Fix a reset query stuck problem (Muhammad Usama) The solution is to return POOL_END_WITH_FRONTEND_ERROR instead of POOL_END when pool_flush on front-end socket fails. The original report is [pgpool-general: 4265] Pgpool - connection hangs in DISCARD ALL =============================================================================== 3.1.16 (hatsuiboshi) 2016/02/05 * Version 3.1.16 This is a bugfix release against pgpool-II 3.1.15. __________________________________________________________________ * Bug fixes - doc: Fix misinformation regarding load balancing in docs (Tatsuo Ishii) In streaming replication mode, DECLARE, FETCH, CLOSE and SHOW are sent to primary node only. Pointed out in [pgpool-general-jp: 1378]. - Issue fsync() when writing pgpool_status (Tatsuo Ishii) This ensures that pgpool_status is saved to permanent storage and allow to survive after system crash. - doc: Fix wrong description about log_standby_delay in the document (Yugo Nagata) - Fix bug with "SET TRANSACTION READ ONLY" (Tatsuo Ishii) Pgpool-II remembers that non read only queries (including SET) were executed in an explicit transaction and adds a "writing transaction" mark to the transaction. The mark affects the query routing behavior of pgpool-II while running in streaming replication mode. Pgpool-II starts sending queries to the primary after the mark is set. Because the effect of writing queries may appear on standbys after some delay in streaming replication mode, it is safer to route read queries to the primary after the mark is set. However there's oversight here. "SET TRANSACTION READ ONLY" does no data modification and should be treated as an exception. Per bug #157. - Fix FATAL error with reloading (Tatsuo Ishii) While reloading pgpool.conf, the number of DB nodes is tentatively set to 0, then counted up until reaching to the actual number of backends by the pgpool main process. Unfortunately the variable was on the shared memory and it confused pgpool child process when they were using the variable and this caused FATAL error. Per bug #156 report by harukat. - Ignore close statement/portal request if they do not exist (Tatsuo Ishii) In this case just returns a close complete message to client. This is a back port of the following commit from pgpool-II 3.4: 1a37e1c35bd8b6f10f524693bbcb7b51f73b4bf0 =============================================================================== 3.1.15 (hatsuiboshi) 2015/07/24 * Version 3.1.15 This is a bugfix release against pgpool-II 3.1.14. __________________________________________________________________ * Bug fixes - Fix "cannot find xlog functions" error in pgpool-recovery (Muhammad Usama) The argument data type of PostgreSQL's pg_xlogfile_name() function has been changed from text to pg_lsn since PostgreSQL 9.4. And pgpool-recovery was still trying to locate the function by old signature. - Do not send a query for checking insert lock in non replication mode with extended query (Tatsuo Ishii) =============================================================================== 3.1.14 (hatsuiboshi) 2015/04/08 * Version 3.1.14 This is a bugfix release against pgpool-II 3.1.13. __________________________________________________________________ * Bug fixes - Enlarge POOLCONFIG_MAXDESCLEN to 80 (Tatsuo Ishii) This is used in show pool_status command and limits the length of parameter description. Unfortunately recovery_timeout description is 64 chars, which is 1 byte longer than former definition of the macro. - Support SSL certificate chains in the certificate file for incoming frontend connections (Muhammad Usama) - Fix a problem with pcp_detach_node about graceful node detach (Muhammad Usama) When graceful node detach is requested gracefully, pcp_detach_node should check if it is allowed to process detach_node command on the particular node before blocking the incoming connections and closing the existing connections. =============================================================================== 3.1.13 (hatsuiboshi) 2015/02/05 * Version 3.1.13 This is a bugfix release against pgpool-II 3.1.12. __________________________________________________________________ * Bug fixes - doc: Describe explicitly that the number of slave nodes is not necessarily 1 (Tatsuo Ishii) - Fix uninitialized variable (Tatsuo Ishii) Per Coverity 1234603. - doc: Fix missing release note entries in the previous release (Tatsuo Ishii) - Fix node id range check bug in trigger_failover_command(). (Tatsuo Ishii) The node id should be lower than NUM_BACKENDS. Probably harmless since callers never pass node ids greater or equal to NUM_BACKENDS. - Fix to disable debug mode by reloading config (Yugo Nagata) Per bug #114 http://www.pgpool.net/mantisbt/view.php?id=114 =============================================================================== 3.1.12 (hatsuiboshi) 2014/09/05 * Version 3.1.12 This is a bugfix release against pgpool-II 3.1.11. __________________________________________________________________ * Bug fixes - Fix a typo of pgpool.spec (Yugo Nagata) - Fix bug that worker child process keeps failing when there's no primary backend (Tatsuo Ishii) Problem identified and fix contributed by Junegunn Choi. See [pgpool-hackers: 471] for more details. - Close listen socket when smart shutdown request is made (Tatsuo Ishii) When smart shutdown process starts, pgpool children still listen on the port and clients can send further connection requests which fail in the end. Which is not only waste of time, but also prevents a load balancer which sits in front of pgpool from realizing the pgpool is going down. Problem analyzed and patch provided by Junegunn Choi in [pgpool-hackers 474], and enhanced to take care not only inet domain socket but UNIX domain socket by Tatsuo Ishii. - doc: Add cautions that recovery commands are killed by statement_timeout of PostgreSQL. (Tatsuo Ishii) - doc: Remove old restriction description which is no longer true (Tatsuo Ishii) - Fix return type of text_to_lsn() function (Yugo Nagata) This caused compile warning. - Fix file descriptor leak when daemonize. (Tatsuo Ishii) Per Coverity 1111471. - Fix memory leak. (Tatsuo Ishii) Per Coverity 1111442. - Fix pgpool.init's long-standing bug of stop/restart failure (Yugo Nagata) In previous, pgpool.init uses killproc for stopping pgpool, but there are several problems. In the new version, "pgpool -m fast stop" is used in stop command. Original patch contributed by Ryan DeShone and modified by Yugo Nagata. See [pgpool-hackers: 239][pgpool-hackers: 512]. - Disable statement_timeout of PostgreSQL while executing online recovery (Tatsuo Ishii) Online recovery may take very long time and user may enable statement timeout. To prevent online recovery canceled by statement timeout, disable statement timeout in the connection used by online recovery. See [pgpool-general: 2919] for more details. - Remove unnecessary call to pool_shmem_exit() which removes semaphore when it shouldn't (Tatsuo Ishii) exit_handler checks if the process is parent or not. This is good. However, even if it is a child process, it calls pool_shmem_exit() which removes semaphore and shmem when it should not. It should be called only from parent process. Per bug #102. http://www.pgpool.net/mantisbt/view.php?id=102 - Fix reset query stuck problem. (Tatsuo Ishii) It is reported that reset query (DISCARD ALL etc.) occasionally does not finish and pgpool child remain waiting for reply from backend thus client cannot connect to pgpool. The cause of problem is not identified yet but if client suddenly closes connection to pgpool in the middle of query processing, backend may not accept the reset queries because they are not ready for query. The fix is, if frontend closes connection in unexpected way, query process loop immediately returns with new state: POOL_END_WITH_FRONTEND_ERROR and pgpool closes connection to PostgreSQL then goes back to new connection request waiting loop. Also, pgpool closes connections to backend when client_idle_limit is set and the idle limit. Per bug #107. http://www.pgpool.net/mantisbt/view.php?id=107 =============================================================================== 3.1.11 (hatsuiboshi) 2014/03/24 * Version 3.1.11 This is a bugfix release against pgpool-II 3.1.10. __________________________________________________________________ * Bug fixes - doc: Add mention about "listen queue" and how to increase the "backlog" in the num_init_children section. (Tatsuo Ishii) - Fix bad performance of unlogged tables detection code. (Tatsuo Ishii) Pointed out at [pgpool-hackers: 435][[pgpool-general:2325]. - Fix primary node detection logic. (Tatsuo Ishii) There's a possibility that primary node is not detected. This happens in following situation. node 0: primary, node 1: standby. Node 0 goes down. Health checking detects the fact but local status is not updated yet. Primary node finding (find_primary_node) runs. Node 0's status is yet healthy. Because find_primary_node fails to connect to node 0, it immediately returns -1 and fails to find that fact that node 1 is now primary. Fix is just continuing to look for primary node when fails to connect to a node. Per [pgpool-general: 2409]. - Fix jdbc DML fails when operated in raw mode and auto commit is off. (Tatsuo Ishii) This is reported in bug #92. - Avoid to send queries to unrelated nodes in streaming replication mode. (Tatsuo Ishii) Pgpool-II sends certain queries, such as BEGIN, END and SET commands to all of DB nodes. However in streaming replication mode, only primary node and at most one standby node are only concerned (if primacy node is selected as the load balance node, only 1 node is concerned). See [pgpool-hackers: 464] for more details. - Fix possible buffer overrun problem and memory leak. (Tatsuo Ishii) Per Coverity 1111465 and 1111482. - Fix possible buffer overrun. (Tatsuo Ishii) Replace strcpy() with strlcpy(). Per Coverity report 1111478, 1111480, 1111481. - Fix freeing NULL. (Tatsuo Ishii) Per Coverity 1111384. - Fix memory leak. (Tatsuo Ishii) Per Coverity 1111446. - Fix a segmentation fault in parallel mode with system_db_hostname is empty (Yugo Nagata) - Fix to output debug messages in processing pgpool.conf with -d option (Yugo Nagata) Previously, some debug messages in pool_get_config() ware not output even when -d option was used. - Fix JDBC exception of prepared statement including now() in replication mode (Yugo Nagata) With JDBC, when a prepared statement is executed more than PrepareThreshold times, the statement is named and Describe message is sent after Parse. With named statement, pgpool rewrite now() to parameter in replication mode. Hence, rewritten query has additional parameter than original. In this case, ParameterDescription message sent to frontend (response of Describe) should include OIDs of the same number os original query's parameters. Otherwize, JDBC throws ArrayIndexoutOfBoundsException. This is reported in [pgpool-general-jp: 1192]. - Fix backend error of prepared statement about table which has column whose default value is now() in replication mode (Yugo Nagata) When pgpool parses a named prepared statement with default now(), timestamps are replaced to additional parameters. So, Bind message also should included additional parameter format codes. However, when the number of original parameter was one, pgpool didn't handle this. This caused a error like "incorrect binary data format in bind parameter 2". - doc: Add description about parallel mode doesn't support PREPARE (Yugo Nagata) Per bug #93 =============================================================================== 3.1.10 (hatsuiboshi) 2013/12/06 * Version 3.1.10 This is a bugfix release against pgpool-II 3.1.9. __________________________________________________________________ * Bug fixes - Fix incorrect time stamp rewriting in replication mode for certain time zones. (Tatsuo Ishii) Time stamp rewriting calls "SELECT now()" to get current time. Unfortunately the buffer for the current time is too small for certain time zones such as "02:30". Note that non-30-minutes-time-zone such as "0900" does not reveal the problem. This explains why we haven't the bug report until today. Bug reported in [pgpool-general: 2113] and fix provided by Sean Hogan. http://www.sraoss.jp/pipermail/pgpool-general/2013-September/002142.html - Makefile: Replace pg_config by $(PG_CONFIG) in Makefiles so it can be overridden at build time when compiling for different PG major versions. (Tatsuo Ishii) Patch contributed by Christoph Berg ([pgpool-general: 2127]). http://www.sraoss.jp/pipermail/pgpool-general/2013-September/002156.html - configure: Remove -lcompat because it confuses FreeBSD per bug#15. (Tatsuo Ishii) http://www.pgpool.net/mantisbt/view.php?id=15 - Fix segfault when pgpool.conf does not set log_standby_delay. (Tatsuo Ishii) This is caused by wrong initialization for log_standby_delay in pool_config.l. Per bug#74. http://www.pgpool.net/mantisbt/view.php?id=74 - doc: Modify descriptions about restrictions of parallel mode Multiple rows INSERT using VALUES are not supported in parallel mode. (Yugo Nagata) - Avoid calling find_primary_node_repeatedly() when standby node goes down. (Tatsuo Ishii) This will reduce the time to failover. Per bug #75, patch modified by Tatsuo Ishii. http://www.pgpool.net/mantisbt/view.php?id=75 - Fix data inconsistency problem with native replication mode + extended protocol case. (Tatsuo Ishii) It is reported that concurrent INSERT using JDBC driver causes data difference among database node. This only happens following conditions are all met: 1) Native replication mode 2) Extended protocol used 3) The portal created by parse message is reused by bind message 4) autocommit is on 5) SERIAL (sequence) is used Pgpool-II's parse message function knows it has to lock the target table when INSERT (plus #5) is issued by clients. Unfortunately bind message function did not know it. Once parse/bind/execute finishes, pgpool releases the lock obtained by parse because of #4. JDBC wants to reuse the portal and starts the cycle from bind message, which does not obtain lock. As as result, lock-free INSERT are floating around which causes data inconsistency of course. The solution is, lock the table in bind phase. For this bind needs to issue LOCK in extended protocol. This was a little bit hard because the module (do_command()) to issue internal SQL command (other than SELECT) does not support extended protocol. To solve the problem do_query() is modified so that it accepts other than SELECT because it already accepts extended protocol. The modification is minimum and is only tested for the case called from insert_lock(). I do not recommend to replace every occurrence of do_command () with do_query() at this point. BTW the reason why the bug is not reported is, most users uses JDBC with auto commit = off. In this case, the lock obtained by parse persists until user explicitly issues commit or rollback. Per bug report by Steve Kuekes in [pgpool-general: 2142]. http://www.sraoss.jp/pipermail/pgpool-general/2013-September/002171.html - Fix error message in read_password_packet(). (Tatsuo Ishii) - Fix memory leak when do_query() fails in timestamp rewriting. (Tatsuo Ishii) For this purpose free_select_result() is changed to accept NULL argument. Per Coverity report "1111454, 1111455 Resource leak". - Fix target node selection logic when "DEALLOCATE portal|statement". (Tatsuo Ishii) When "DEALLOCATE portal|statement" is used and last prepared statement or portal was not found, target node selection map is not set. Probably this is not actually harmful because prepared statement or portal was not found is an error case. The bug was there since day 0. Per Coverity report "1111491 Structurally dead code". - Fix range check bug of MAX_NUM_BACKENDS in corner case. (Tatsuo Ishii) MAX_NUM_BACKENDS is the allowed max number of DB nodes (128, at this point). In reality, probably no one ever tried more than 128 DB nodes and that's the reason why nobody noticed. Per Coverity report "1111429, 1111430 and 1111431 Out-of-bounds write". - Fix that the script forgets to allow public access to pgpool_catalog. (Tatsuo Ishii) The bug prevents inserting data into user tables if pgpool_catalog is created in native replication mode. The bug was there from day 1. I wonder why nobody noticed until today. Per [pgpool-general-jp: 1229]. http://www.sraoss.jp/pipermail/pgpool-general-jp/2013-November/001228.html - Fix uninitialized variable in error case in pool_do_auth(). (Tatsuo Ishii) If there's no valid backend, pgpool will return garbage pid to frontend in auth phase. Actually because no backend is available, frontend will be disconnected later on. So this is not harmless. Per Coverity report "1127331 Uninitialized scalar variable". - Fix to add node id range check when issue an error message using node id. (Tatsuo Ishii) Per Coverity report #1111433 "Out-of-bounds read". - Fix buffer overrun bug and resource leak bug of parse_copy_data(). (Tatsuo Ishii) Per Coverity report 1111427 "Out-of-bounds write" and 1111453 "Resource leak". - Fix possible segfault in CopyDataRaws(). (Tatsuo Ishii) Coverity pointed out that if pool_get_id() returns an error, VALID_BACKEND will access out of array. Per Coverity report 1111413 "Memory - illegal accesses". - Fix resource leak in make_persistent_db_connection. (Tatsuo Ishii) For this purpose, new static function free_persisten_db_connection_memory is added. Per Coverity report #1111468. =============================================================================== 3.1.9 (hatsuiboshi) 2013/09/06 * Version 3.1.9 This is a bugfix release against pgpool-II 3.1.8. __________________________________________________________________ * Bug fixes - Fix a mistake in ssh command of doc/basebackup.sh (Tatsuo Ishii) - Fix a bug in parsing prepared statements with transaction handling in replication mode (Tatsuo Ishii) Parse() automatically starts a transaction for non SELECT query to keep consistency among nodes in replication mode. But this wasn't closed. If wrong query comes in, the transaction goes into an abort state but pgpool does not close the transaction. Thus next query causes error because the transaction is still in abort status. This problem was reported in [pgpool-general: 1877] by Sean Hogan. [pgpool-general: 1877] current transaction is aborted, commands ignored http://www.sraoss.jp/pipermail/pgpool-general/2013-July/001905.html - Fix typos of the japanese document (Yugo Nagata) =============================================================================== 3.1.8 (hatsuiboshi) 2013/07/10 * Version 3.1.8 This is a bugfix release against pgpool-II 3.1.7. __________________________________________________________________ * Bug fixes - Add mention about "-D" option to the man page. (Tatsuo Ishii) - Consider timeout waiting for completion of failback request in on line recovery (Tatsuo Ishii) This will prevent the situation that recovery operation continues forever and we cannot even shutdown pgpool-II main process. This could happen especially while executing follow master command. - Fix a bug that %H of follow_master_command is not assigned correctly the new primary node in stream replication mode (Tatsuo Ishii) - Fix do_query() to not hang when PostgreSQL returns an error (Tatsuo Ishii) The typical symptom is "I see SELECT is keep on running according to pg_stat_activity". To fix this pgpool-II just exits the process and kill the existing connection. This is not gentle but at this point I believe this is the best solution. - Fix bug with do_query which causes hung in extended protocol (Tatsuo Ishii) This problem could occur when insert lock is enabled and pgpool_catalog.insert_lock exists, See [pgpool-general: 1684] for more details. [pgpool-general: 1684] insert_lock hangs http://www.sraoss.jp/pipermail/pgpool-general/2013-May/001711.html - Fix unnecessary degeneration caused by error on commit (Tatsuo Ishii) In master slave mode, if master gets an error at commit, while other slaves are normal at commit, we don't need to degenerate any backend because it is likely that the "kind mismatch error" was caused by a deferred trigger. - Fix to register pgpool_regclass in pg_catalog schema (Tatsuo Ishii) This is necessary to deal with clients which restricts schema search path to pg_catalog only. Postgres_fdw is such a client. - Fix a potential crash in pg_md5 command (Muhammad Usama) - Fix a segmentation fault of a child process that occurs when a startup packet has no PostgreSQL user information (Yugo Nagata) You can reproduce it by $ psql -p 9999 -U '' If enable_pool_hba is on, a child process terminates by segmentation fault. Otherwise if enable_pool_hba is off, the error message is ERROR: pool_discard_cp: cannot get connection pool for user (null) database (null) In both cases, psql terminates with no message on frontend. In the fixed version, if PostgreSQL user is not specified in startup packet, the message as following is output to both log and frontend. This is the same behavior as PostgreSQL. FATAL: no PostgreSQL user name specified in startup packet - Move ssl_ca_cert and ssl_ca_cert_dir descriptions to the SSL section (Yugo Nagata) - Add ssl_ca_cert and ssl_ca_cert_dir descriptions to the japanese document (Yugo Nagata) - Fix to verify the backend node number in pcp_recovery_node (Yugo Nagata) When an invalid number is used, null value is passed as an arguments of recovery script, and this causes a malfunction. In especially, rsync may delete unrelated files in basebackup scripts. =============================================================================== 3.1.7 (hatsuiboshi) 2013/4/26 * Version 3.1.7 This is a bugfix release against pgpool-II 3.1.6 __________________________________________________________________ * Bug fixes - Fix to show pool_passwd in "SHOW pool_status". (Yugo Nagata) - Fix long standing bug with timestamp rewriting code for processing extended protocol. (Tatsuo Ishii) Parse() allocate memory using palloc() while rewriting the parse message. Problem is, the rewritten message was kept in the data which is managed by pool_create_sent_message() etc. The function assumes that all the data is in session context memory. However, palloc() allocates memory in query context of course, and gets freed later on when the query context disappears. And the function tries to free the memory as well, which causes various problems, including segfault and double free. To fix this, memory to store rewritten message is allocated using session context. The bug was there since pgpool-II 3.0 was born. Problem analysis and patch contributed by Naoya Anzai. [pgpoolgenera-jp: 1146]. (in Japanese) http://www.pgpool.net/pipermail/pgpool-general-jp/2013-March/001145.html - Fix bug with md5 auth long user name handling.

(Yugo Nagata) When the primary server is behind from standby server, negative value of delay is calculated and the value is assigned to unsigned variable. It causes a log message informing negative replication delay. And what is worse, it also causes SELECT queries to be sent to the primary in load balance even though there are no replication delay in fact. The problem is reported and analyzed by Saitoh Hidenori in [pgpool-genera-jp: 1145].

(Tatsuo Ishii) Even though pgpool_regclass() exists, if pgpool cannot execute the function, the connection to backend hangs. You can reproduce the problem by just dropping the execute privilege from pgpool_regclass and do some insert in native replication mode.

(Tatsuo Ishii) The file descriptor to pool_passwd is opened in pgpool main and pgpool child inherits it. When concurrent connections try to authenticate md5 method, they call pool_get_passwd and seek the fd and cause random md5 auth failure because underlying fd is shared. Fix is, let individual pgpool child open the file by calling pool_reopen_passwd_file. Problem reported and analyzed by Jason Slagle in pgpool-general:1141. [pgpool-general: 1141] Possible race condition in pool_get_passwd From: Jason Slagle Date: Sun, 28 Oct 2012 01:12:52 -0400 http://www.sraoss.jp/pipermail/pgpool-general/2012-October/001160.html - Fix hung up while repeating pcp_attach_node and pcp_detach_node (Tatsuo Ishii) When node status is changed by pcp_attach_node and pcp_detach_node, failover() sends SIGUSR1 to pcp_child process expecting it exits to refresh node status. In this situation lots of pgpool children exit and produce SIGCHLD as well. The SIGCHLD handler reaper() tries catch all SIGCHLD but sometimes it fails depending on the system load and timing. If SIGCHLD produced by pcp child is not caught, the process becomes zombie and never restarted. This problem is reported in bug track #32 (by oleg_myrk) etc. #32 PGPool hangs on pcp_attach/detach Reporter: oleg_myrk $B!!(BDate: 2012-10-24 00:01 http://www.pgpool.net/mantisbt/view.php?id=32 - Fix pool_send_severity_message() not to use uninitialized memory.

Problem reported and fix suggested by Goto in [pgpool-general-jp: 1123]. http://www.sraoss.jp/pipermail/pgpool-general-jp/2012-November/001122.html (in Japanese) - Fix pool_search_relcache() to use MASTER or MASTER_NODE_ID macro, rather than REAL_MASTER_NODE_ID. (Tatsuo Ishii) In case node 0 fail back in streaming replication mode, pgpool does not restart child process. So REAL_MASTER_NODE_ID looks for node 0 con info, which is not present until new connection to backend made. Thus referring to node con info results in segfault. MASTER or MASTER_NODE_ID are safe in this situation because they look at cached former master node id. - Fix long standing bug "portal not found" error when replication delay is too much in streaming replication mode. (Tatsuo Ishii) The bug had been there since the delay threshold was introduced. We changed destination DB node if delay threshold exceeds in bind, describe and execute. However, if parse sends to different node, bind, describe or execute will fail because no parsed statement or portal exists. Solution is, not to send to different parse node even if delay threshold is too much. - Fix pg_md5 to output "\n" after user inputs password. (Yugo Nagata) - Fix child_exit() to not call send_frontend_exits() if there's no connection pool. (Tatsuo Ishii) Otherwise, it segfaults because send_frontend_exits() refers to objects pointed to by pool_connection_pool. Per bug track #44 by tuomas. #44 pgpool went haywire after slave shutdown triggering master failover Reporter: tuomas Date: 2012-12-11 00:33 http://www.pgpool.net/mantisbt/view.php?id=4 - Fix read_startup_packet() to reset alarm and free StartupPacket when pool_read() returns 0 which means incorrect packet length. (Nozomi Anzai) Previously, authentication timeout occurs when connected by a program monitoring the pgpool port.It is reported in bug track #35 by tuomas. #35 Authentication is timeout Reporter: tuomas Date: 2012-11-20 11:54 http://www.pgpool.net/mantisbt/view.php?id=3 - Fix long standing bug with pool_open(). (Tatsuo Ishii) It initializes wrong buffer pointer. Actually this is harmless because the pointer is initialized by prior memset() call, though. - Modify documents to correct information of whether a certain parameter change requires restart. (Yugo Nagata) - Add pool_passwd option to pgpool.conf.sample*, and documents. (Yugo Nagata) =============================================================================== 3.1.5 (hatsuiboshi) 2012/10/12 * Version 3.1.5 This is a bugfix release against pgpool-II 3.1.4 __________________________________________________________________ * Bug fixes - Fix read_startup_packet. (Tatsuo Ishii) If packet length is lower than 0, it should have returned immediately. Otherwise it would cause memory allocation error later on. per pgpool-general:886. Also add canceling alarm. - Add NOTICE message handling to s_do_auth. (Tatsuo Ishii) Without this, health check responses false alarm and causes failover. per bug track: http://www.pgpool.net/mantisbt/view.php?id=25 Also allow to receive ready for query packet *not* right after backend keydata. I'm not sure if this could happen in the real world but the protocol seems to allow this. - Remove unnecessary/confusing debug log from s_do_auth.(Tatsuo Ishii) - Fix infinite loop in SSL mode. When there's pending data in SSL layer of frontend, pool_process_query() checks pending data in backend. (Tatsuo Ishii) If there's non, it loops again and checks frontend/backend receive buffer by using is_cache_empty(). Unfortunately it first checks pending data in SSL layer of frontend, thus goes to backend data and checks again (infinite loop). The solution is, if there's pending data in SSL layer of frontend and query is not in progress, call ProcessFrontendResponse() to process new request from frontend. - Fix is_system_catalog to use pgpool_regclass if available. (Tatsuo Ishii) - Fix memory leak in pool_get_insert_table_name(). (Tatsuo Ishii) If session context's memory contex is used for nodeToString(), memory is not freed until session ends. - Fix possible memory leak in nodeToString(). (Tatsuo Ishii) Since the memory context could be session context, memory used for String object may be considerable if user session continues for hours or days. See bug track #24 for more details. - Fix long standing problem with do_query(). (Tatsuo Ishii) When 1) extended protocol used and 2)unnamed portal is used and 3) no explicit transaction is used, user's unnamed portal is removed by Sync message. This is because Sync message closes transaction and unnamed portal is removed. This leads to "portal "" does not exist" error. Fix is, use "Flush" message instead of Sync. Main difference between using Sync and Flush is, Flush does not return Ready for Query message. So do_query() does not return until all expected responses are returned. It seems the order of messages returned from backend is random, and do_query () manages it by using state bits. =============================================================================== 3.1.4 (hatsuiboshi) 2012/08/06 * Version 3.1.4 This is a bugfix release against pgpool-II 3.1.3. __________________________________________________________________ * General - Adopt PostgreSQL 9.2. (Tatsuo Ishii) __________________________________________________________________ * Bug fixes - Fix pool_send_and_wait() to send or not to send COMMIT / ABORT depending on the transaction state on each node. (Tatsuo Ishii) It is possible that only primary is in an explicit transaction but standby is not in it if multi statement query has been sent. Per bug report [pgpool-general-jp: 1049]. - Fix load balance in Solaris. (Tatsuo Ishii) Problem is, random() in using random() in Solaris results in strange load balancing calculation. Use srand()/rand() instead although they produce lesser quality random Problem reported at [pgpool-general: 396]. [pgpool-general: 396] strange load balancing issue in Solaris http://www.pgpool.net/pipermail/pgpool-general/2012-April/000397.html - Add params to the result of "SHOW pool_status": backend_data_directory, ssl_ca_cert, ssl_ca_cert_dir. (Nozomi Anzai) - Fix segfault of pcp_systemdb_info not in parallel mode. (Nozomi Anzai) - Fix "unnamed prepared statement does not exist" error. (Tatsuo Ishii) This is caused by pgpool's internal query, which breaks client's unnamed statements. To fix this, if extended query is used, named statement/portal for internal are used for internal query. - Fix is_system_catalog(). Its relcache was accidently defined as "session local". (Tatsuo Ishii) - Fix hangup when query conflict occurs in Hot-Standby mode. (Yugo Nagata) Query example to reproduce: (S1) BEGIN; (S1) SELECT * FROM t; (S2) DELETE FROM t; (S2) VACUUM t; - Improve reading and writing pid_file. (Tatsuo Ishii) - Fix pool_process_query() bug reported in [pgpool-general: 672]. (Tatsuo Ishii) This is caused by the function waits for primary node which does not have pending data, while standbys have pending data. [pgpool-general: 672] Transaction never finishes http://www.pgpool.net/pipermail/pgpool-general/2012-June/000676.html - Fix wait_for_query_response() not to send param status to frontend if frontend is NULL. (Tatsuo Ishii) This could happen while processing reset_query_list and occur crash. - Fix bug with treatment of BEGIN TRANSACTION in master/slave mode. (Tatsuo Ishii) Original complain is [pgpool-general: 714]. From 3.1, pgpool-II sends BEGIN.. to all DB nodes. Of course we cannot send BEGIN TRANSACTION READ WRITE to standby nodes. Problem is, we did not check BEGIN WORK ISOLATION LEVEL SERIALIZABLE; and sent to standby nodes. Of course this is wrong, since it's not allowed to run transactions in serializable mode on standby nodes. So added check for BEGIN WORK ISOLATION LEVEL SERIALIZABLE case. [pgpool-general: 714] Load Balancing / Streaming Replication / Isolation Level serializable http://www.pgpool.net/pipermail/pgpool-general/2012-July/000719.html - Fix send_to_where() to send the query to only primary if the it is like SET TRANSACTION ISOLATION LEVELSERIALIZABLE etc. (Tatsuo Ishii) Case in streaming replication mode. Previously, it was sent to not only primary but also to standby and of course this causes an error. Similar SQLs are: SET SESSION CHARACTERISTICS AS TRANSACTION ISOLATION LEVEL SERIALIZABLE or SET transaction_isolation TO 'serializable' SET default_transaction_isolation TO 'serializable' Original complain is [pgpool-general: 715]. [pgpool-general: 715] Re: Load Balancing / Streaming Replication / Isolation Level serializable http://www.pgpool.net/pipermail/pgpool-general/2012-July/000720.html =============================================================================== 3.1.3 (hatsuiboshi) 2012/04/23 * Version 3.1.3 This is a bugfix release against pgpool-II 3.1.2. __________________________________________________________________ * Bug fixes - Add m4 files. This should prevent compiling problem on older OS's. (Tatsuo Ishii) - Fix to handle failover properly in detect_postmaster_down_error(). (Tatsuo Ishii) It is possible that it fails to read backend socket after detecting backend errors and before actually detaching the backend. - Fix bug that the process exits before unlocking semaphore by a signal interrupt. (Tatsuo Ishii) - Fix a memory leak in case of reset_query. (Tatsuo Ishii) - Fix pool_ssl_read() to deal with large data reading. (Tatsuo Ishii) Original complain is here: http://www.pgpool.net/pipermail/pgpool-general/2012-March/000299.html - Fix deadlock by enabling log_destination = syslog. (Tatsuo Ishii) Reported in bug tracker http://www.pgpool.net/mantisbt/view.php?id=9. Patch provided by Gilles Darold. - Allow to use multi statement in master/slave mode. (Tatsuo Ishii) From 3.1 transactional statements such as "BEGIN" are sent to not only primary but also standbys. This brings an unfortunate side effect: if the multi statement is "BEGIN;DELETE FROM table;END", this will be sent to standby as well and cause an error because standby does notallow write SQL. So fix is, if a query is a multi statement one, then send it to primary only. - Allow to have private cache of master node id. (Tatsuo Ishii) When master goes down running pgpool children look into NULL pointer because the process does not connect to the new master yet. The private cache returns the old master node id and will avoid the situation. Per bug reported in http://www.pgpool.net/mantisbt/view.php?id=51 - Fix pool_start_query() so that it uses my_master_node_id instead of REAL_MASTER_NODE_ID for initial virtual_master_node_id. (Tatsuo Ishii) Real master node could be changed while pgpool is running in streaming replication mode. Previously it is assigned REAL_MASTER_NODE_ID, which could have no connections after fail over and cause segfault. - Fix pool_setall_node_to_be_sent() to use private_backend_status instead of BACKEND_INFO macro. (Tatsuo Ishii) It is possible that while processing, the node returned by BACKEND_INFO is not usable any more. - Fix failover(). (Tatsuo Ishii) Before it only restarts worker child only when pgpool child do not need restart. This is wrong. We need to restart worker child in any case. Otherwise it continues to send replication time lag check request to down the node. - Fix debug log message so that it does not contain null characters. (Toshihiro Kitagawa) - Fix SimpleQuery() so that it restores parser memory context when: 1) Builtin show commands are used 2) Parallel query mode 3) Query cache is used (Tatsuo Ishii) - Fix hangup when PREPARE statement causes error. (Toshihiro Kitagawa) This issue was reported by Tomonari Katsumata: Subject: [pgpool-general: 121] question of pgpool's behavior - Add doc/pgpool-fr.html to Makefile.am. (Tatsuo Ishii) This had been forgotten when the doc was added. - Fix hangup during md5 authentication that occurs in daemon mode and log_destination is 'syslog'. (Yugo Nagata) Reported in bug tracker http://www.pgpool.net/mantisbt/view.php?id=2. =============================================================================== 3.1.2 (hatsuiboshi) 2012/01/31 * Version 3.1.2 This is a bugfix release against pgpool-II 3.1.1. __________________________________________________________________ * Bug fixes - Fix to recognize READ UNCOMMITTED and REPEATABLE READ of transaction isolation levels. (Tatsuo Ishii) - Fix infinite loop reported in this thread (Tatsuo Ishii): http://www.pgpool.net/pipermail/pgpool-general/2011-December/000099.html It was not considered the case that, when received buffer in primary was empty but the one in a standby was not, the standby spontaneously sent packet to pgpool. This could happen when, for example, reloading postgresql.conf. The fix is that such buffer in standby is discarded. =============================================================================== 3.1.1 (hatsuiboshi) 2011/12/06 * Version 3.1.1 This is a bugfix release against pgpool-II 3.1. __________________________________________________________________ * Bug fixes - Fix add_regex_pattern(). It does not allocate enough memory for each black/white_function_list items. The function adds "^" and "$" to each function items which do not contain those characters. Unfortunately the function forgot to add extra 2 bytes for those characters. This may lead to memory corruption errors when pgpool starting up. - Fix error message of check_replication_time_lag(Tatsuo Ishii). It emitted wrong error message when it failed to connect to PostgreSQL while checking streaming replication delay. Because it does not use health_check_user anymore. - Fix memory leak(Toshihiro Kitagawa). This is essentially same as the fix made for 3.0.5(commit 19a4ea9215da0b61728741fc0da2271958b09238). - Major cleanup for strncpy(Tatsuo Ishii). There are several places where strncpy() is used. Problem is some of them do not consider the case when copy length == buffer size. In this case copied buffer is not null terminated and may cause tons of problems later. To fix this, most of them are replaced by strlcpy(). - Update cached backend status whenever possible(Tatsuo Ishii). This solves the problem of follow_master_command not being able to lookup backend status correctly which was reported by Jeff Frost: Subject: [Pgpool-general] diagnosing BackendError from pcp_recovery_node To: pgpool-general@pgfoundry.org Date: Wed, 05 Oct 2011 15:15:07 -0700 - Fix buffer overrun problem when pcp password is longer than 32(Tatsuo Ishii). - Remove PGDLLIMPORTI which is only necessary for Windows and cause a problem for non gcc. Patch contributed by Ibrar Ahmed. =============================================================================== 3.1 (hatsuiboshi) 2011/09/08 * Version 3.1 This is the first version of pgpool-II 3.1 series. That is, a "major version up" from 3.0 series. __________________________________________________________________ * Incompatible changes - Change the lock method of insert_lock. The previous insert_lock uses row locking against the sequence relation, but the current one uses row locking against pgpool_catalog.insert_lock table. The reason is that PostgreSQL core developers decided to disallow row locking against the sequence relation to avoid an internal error which it leads. So creating insert_lock table in all databases which are accessed via pgpool-II beforehand is required. If does not exist insert_lock table, pgpool-II locks the insert target table. This behavior is same as pgpool-II 2.2 and 2.3 series. If you want to use insert_lock which is compatible with older releases, you can specify lock method by configure options: --enable-sequence-lock, --enable-table-lock(Toshihiro Kitagawa) - Deprecate backend_socket_dir. Instead, if backend_hostname starts with '/' it is regarded the as path to Unix domain. If backend_hostname is left empty, then default Unix domain path(/tmp) is used. This follows the convention of libpq interface. Patch contributed by Jehan-Guillaume (ioguix) de Rorthais. - Now "pgpool_walrecrunning()" was not used. pgpool-II used to consider the node that is promoted a primary node using the function. Now, pgpool-II waits for completing of the promotion to primary node because it did not work as we intended. But we still have a problem that pgpool-II waits while recovery_timeout, when there is no primary node(Toshihiro Kitagawa) - Add node_id to each PostgreSQL DB node info in the output of show pool_nodes(Jean-Paul Argudo) - Change the handling of sequence functions(nextval, setval) so that they completely obey setting of black/white_function_list. They were always handled as write functions before(Toshihiro Kitagawa) __________________________________________________________________ * New features - Add syslog support. Patch contributed by Gilles Darold. Review and editing by Guillaume Lelarge. - Adapt application_name introduced in PostgreSQL 9.0. When reusing connection, send application_name in the startup packet to backend and send parameter status to frontend(Tatsuo Ishii) - Add relcache_expire directive to control the expiration of the internal system catalog cache. ALTER TABLE might make these cache values obsoleted and the new directive will make the risk lower(Tatsuo Ishii). - Add follow_master_command directive. This directive specifies a command to run in master/slave streaming replication only after a master failover. Patch contributed by Gilles Darold. - Add pcp_promote_node command. This command promotes a new master node to pgpool-II. This can use in master/slave streaming replication only. Patch contributed by Gilles Darold. - Add pcp_pool_status command which produces similar output of show pool_status. Also C API for this command is added. Patch contributed by Jehan-Guillaume (ioguix) de Rorthais. - Add new per backend directive "backend_flag". This controls per backend behavior. Currently "ALLOW_TO_FAILOVER" or "DISALLOW_TO_FAILOVER" are allowed(Tatsuo Ishii) - Add health_check_password directive, but is not yet implemented (Nicolas Thauvin) - Add sr_check_period, sr_check_user and sr_check_password directives. These are used for streaming replication delay checking and determining primary node(Tatsuo Ishii) - Add --username(or -u) option to pg_md5 command. This allows to manage users which do not have UNIX accounts. Japanese document change by Tatsuo Ishii(Nicolas Thauvin) - Add pgpool_adm functions to pgpool_adm/. These are user-defined functions written in C language which work like pcp commands (Jehan-Guillaume (ioguix) de Rorthais) - Add Simplified Chinese version of documents(Huang Jian, Sun Peng) - Add SQL files to uninstall functions to sql/(Nicolas Thauvin) - In master/slave mode, SELECTs to unlogged table execute only on master/primary(Toshihiro Kitagawa) __________________________________________________________________ * Bug fixes - Fix bug which cannot use the cursors of JDBC driver on standby node. The transaction commands come to be sent to all nodes by this fix in master/slave mode(Toshihiro Kitagawa) - Fix bug with the handling of empty queries. The empty queries come to be handled the same as SELECT queries. This fix allows load-balance after the empty query(Toshihiro Kitagawa) - Fix insert_lock so that it works correctly even if the column definition such as "DEFAULT nextval(('"x_seq"'::text)::regclass)" (Toshihiro Kitagawa) - Fix pcp_attach_node command so that it emits error message while doing failover(Toshihiro Kitagawa) - Fix log message which is emitted when pgpool-II cannot parse the query in the extended query protocol so that it shows the query (Toshihiro Kitagawa) - Fix description about backend_weight inpgpool-II manual. It can be changed by reloading pgpool.conf(Tatsuo Ishii) - Fix and enhance wording in English tutorial document. Fix suggested by Huang Jian(Tatsuo Ishii) - Fix bug which does not update the node status when reattaching the node in raw mode(Guillaume Lelarge) - Fix incorrect calculation of the replication delay in streaming replication mode(Tatsuo Ishii) - Replace wrong function name "notice_backend_error" with correct one "degenerate_backend_set" in the failover log message(Tatsuo Ishii) - Remove unnecessary logging at the end of pgpool.conf parsing(Tatsuo Ishii) - Fix possible crash of pgpool/worker child after attaching new backend. Fix suggested by Gurjeet Singh(Tatsuo Ishii) - Fix bug that SELECTs which have subquery with FOR SHARE/UPDATE clause are sent to slave/standby(Tatsuo Ishii) - Fix bug which rewriting timestamp of default value fails in PREPARE statements. This used to work but was broken in 3.0(Toshihiro Kitagawa) - Fix fail to compile pcp commands on the environment without getopt_long()(Tatsuo Ishii) - Fix crash of pgpool child when frontend connects if in raw mode, enable_hba is off and more than 2 backends(Toshihiro Kitagawa) - Fix some memory leaks(Toshihiro Kitagawa) __________________________________________________________________ * Enhancements - Enhance online recovery in streaming replication mode. Now restarting pgpool-II children is avoided when recovery finished. So existing sessions can be continued while doing online recovery(Tatsuo Ishii) - pcp_attach_node does not disconnect existing sessions in streaming replication mode. In other mode, pcp_attach_node still disconnects existing sessions(Tatsuo Ishii). - Import PostgreSQL 9.0 parser. This allows to use CREATE INDEX with implicit index name, which is new in 9.0. Patch contributed by Akio Ishida. - Allow to use regular expressions in black and white function list. Patch contributed by Gilles Darold. Patch reviewed by Guillaume Lelarge. - Reorganize pgpool.conf sample files so that they are easier to read (Guillaume Lelarge) - Add tags into all parameters in the pgpool-II user manual(Haruka Takatsuka) - Enhance online recovery documents in streaming replication(Tatsuo Ishii) - Change the function to check the replication delay in streaming replication mode. Currently, pgpool uses pg_last_xlog_replay_location() instead of pg_last_xlog_receive_location(). Fix suggested by Anton Yuzhaninov (Tatsuo Ishii) - Allow time stamp rewriting to work with arbitrary expression in default value of a column. Before we detected anything including now() then simply replaced it to now(). This will lead to wrong rewriting of default value. for example, timezone('utc'::text, now()). Note that, however, this only adopts to simple queries. Extended protocols(for example Java, PHP PDO) or SQL "PREPARE" still remain same(Tatsuo Ishii) - Enhance the error message which is emitted when failed to check replication delay(Nicolas Thauvin) - Change error message "do_md5: read_password_packet failed" into debug level(Toshihiro Kitagawa) - Allow to compile pgpool-regclass() against PostgreSQL 9.1(Tatsuo Ishii) - Update and sync pgpool-II manuals of English version and Japanese version(Tatsuo Ishii) =============================================================================== 3.0 Series (2013/07/30 - ) =============================================================================== 3.0.20 (umiyameboshi) 2016/02/05 * Version 3.0.20 This is a bugfix release against pgpool-II 3.0.19. This is the final release of the series. pgpool-II 3.0 has reached End of Life, and is no longer maintained and does not receive any updates. __________________________________________________________________ * Bug fixes - doc: Fix misinformation regarding load balancing in docs (Tatsuo Ishii) In streaming replication mode, DECLARE, FETCH, CLOSE and SHOW are sent to primary node only. Pointed out in [pgpool-general-jp: 1378]. - Issue fsync() when writing pgpool_status (Tatsuo Ishii) This ensures that pgpool_status is saved to permanent storage and allow to survive after system crash. - doc: Fix wrong description about log_standby_delay in the document (Yugo Nagata) - Fix bug with "SET TRANSACTION READ ONLY" (Tatsuo Ishii) Pgpool-II remembers that non read only queries (including SET) were executed in an explicit transaction and adds a "writing transaction" mark to the transaction. The mark affects the query routing behavior of pgpool-II while running in streaming replication mode. Pgpool-II starts sending queries to the primary after the mark is set. Because the effect of writing queries may appear on standbys after some delay in streaming replication mode, it is safer to route read queries to the primary after the mark is set. However there's oversight here. "SET TRANSACTION READ ONLY" does no data modification and should be treated as an exception. Per bug #157. - Fix FATAL error with reloading (Tatsuo Ishii) While reloading pgpool.conf, the number of DB nodes is tentatively set to 0, then counted up until reaching to the actual number of backends by the pgpool main process. Unfortunately the variable was on the shared memory and it confused pgpool child process when they were using the variable and this caused FATAL error. Per bug #156 report by harukat. - Ignore close statement/portal request if they do not exist (Tatsuo Ishii) In this case just returns a close complete message to client. This is a back port of the following commit from pgpool-II 3.4: 1a37e1c35bd8b6f10f524693bbcb7b51f73b4bf0 =============================================================================== 3.0.19 (umiyameboshi) 2015/07/24 * Version 3.0.19 This is a bugfix release against pgpool-II 3.0.18. __________________________________________________________________ * Bug fixes - Fix "cannot find xlog functions" error in pgpool-recovery (Muhammad Usama) The argument data type of PostgreSQL's pg_xlogfile_name() function has been changed from text to pg_lsn since PostgreSQL 9.4. And pgpool-recovery was still trying to locate the function by old signature. - Do not send a query for checking insert lock in non replication mode with extended query (Tatsuo Ishii) =============================================================================== 3.0.18 (umiyameboshi) 2015/04/08 * Version 3.0.18 This is a bugfix release against pgpool-II 3.0.17. __________________________________________________________________ * Bug fixes - Enlarge POOLCONFIG_MAXDESCLEN to 80 (Tatsuo Ishii) This is used in show pool_status command and limits the length of parameter description. Unfortunately recovery_timeout description is 64 chars, which is 1 byte longer than former definition of the macro. - Support SSL certificate chains in the certificate file for incoming frontend connections (Muhammad Usama) - Fix a problem with pcp_detach_node about graceful node detach (Muhammad Usama) When graceful node detach is requested gracefully, pcp_detach_node should check if it is allowed to process detach_node command on the particular node before blocking the incoming connections and closing the existing connections. =============================================================================== 3.0.17 (umiyameboshi) 2015/02/05 * Version 3.0.17 This is a bugfix release against pgpool-II 3.0.16. __________________________________________________________________ * Bug fixes - doc: Describe explicitly that the number of slave nodes is not necessarily 1 (Tatsuo Ishii) - Fix uninitialized variable (Tatsuo Ishii) Per Coverity 1234603. - doc: Fix missing release note entries in the previous release (Tatsuo Ishii) - Fix node id range check bug in trigger_failover_command(). (Tatsuo Ishii) The node id should be lower than NUM_BACKENDS. Probably harmless since callers never pass node ids greater or equal to NUM_BACKENDS. - Fix to disable debug mode by reloading config (Yugo Nagata) Per bug #114 http://www.pgpool.net/mantisbt/view.php?id=114 =============================================================================== 3.0.16 (umiyameboshi) 2014/09/05 * Version 3.0.16 This is a bugfix release against pgpool-II 3.0.15. __________________________________________________________________ * Bug fixes - Fix a typo of pgpool.spec (Yugo Nagata) - Fix bug that worker child process keeps failing when there's no primary backend (Tatsuo Ishii) Problem identified and fix contributed by Junegunn Choi. See [pgpool-hackers: 471] for more details. - Close listen socket when smart shutdown request is made (Tatsuo Ishii) When smart shutdown process starts, pgpool children still listen on the port and clients can send further connection requests which fail in the end. Which is not only waste of time, but also prevents a load balancer which sits in front of pgpool from realizing the pgpool is going down. Problem analyzed and patch provided by Junegunn Choi in [pgpool-hackers 474], and enhanced to take care not only inet domain socket but UNIX domain socket by Tatsuo Ishii. - doc: Add cautions that recovery commands are killed by statement_timeout of PostgreSQL. (Tatsuo Ishii) - doc: Remove old restriction description which is no longer true (Tatsuo Ishii) - Fix return type of text_to_lsn() function (Yugo Nagata) This caused compile warning. - Fix file descriptor leak when daemonize. (Tatsuo Ishii) Per Coverity 1111471. - Fix memory leak. (Tatsuo Ishii) Per Coverity 1111442. - Fix pgpool.init's long-standing bug of stop/restart failure (Yugo Nagata) In previous, pgpool.init uses killproc for stopping pgpool, but there are several problems. In the new version, "pgpool -m fast stop" is used in stop command. Original patch contributed by Ryan DeShone and modified by Yugo Nagata. See [pgpool-hackers: 239][pgpool-hackers: 512]. - Disable statement_timeout of PostgreSQL while executing online recovery (Tatsuo Ishii) Online recovery may take very long time and user may enable statement timeout. To prevent online recovery canceled by statement timeout, disable statement timeout in the connection used by online recovery. See [pgpool-general: 2919] for more details. - Remove unnecessary call to pool_shmem_exit() which removes semaphore when it shouldn't (Tatsuo Ishii) exit_handler checks if the process is parent or not. This is good. However, even if it is a child process, it calls pool_shmem_exit() which removes semaphore and shmem when it should not. It should be called only from parent process. Per bug #102. http://www.pgpool.net/mantisbt/view.php?id=102 =============================================================================== 3.0.15 (umiyameboshi) 2014/03/24 * Version 3.0.15 This is a bugfix release against pgpool-II 3.0.14. __________________________________________________________________ * Bug fixes - doc: Add mention about "listen queue" and how to increase the "backlog" in the num_init_children section. (Tatsuo Ishii) - Fix bad performance of unlogged tables detection code. (Tatsuo Ishii) Pointed out at [pgpool-hackers: 435][[pgpool-general:2325]. - Fix primary node detection logic. (Tatsuo Ishii) There's a possibility that primary node is not detected. This happens in following situation. node 0: primary, node 1: standby. Node 0 goes down. Health checking detects the fact but local status is not updated yet. Primary node finding (find_primary_node) runs. Node 0's status is yet healthy. Because find_primary_node fails to connect to node 0, it immediately returns -1 and fails to find that fact that node 1 is now primary. Fix is just continuing to look for primary node when fails to connect to a node. Per [pgpool-general: 2409]. - Fix jdbc DML fails when operated in raw mode and auto commit is off. (Tatsuo Ishii) This is reported in bug #92. - Avoid to send queries to unrelated nodes in streaming replication mode. (Tatsuo Ishii) Pgpool-II sends certain queries, such as BEGIN, END and SET commands to all of DB nodes. However in streaming replication mode, only primary node and at most one standby node are only concerned (if primacy node is selected as the load balance node, only 1 node is concerned).

(Tatsuo Ishii) Per Coverity 1111446. - Fix a segmentation fault in parallel mode with system_db_hostname is empty (Yugo Nagata) - Fix to output debug messages in processing pgpool.conf with -d option (Yugo Nagata) Previously, some debug messages in pool_get_config() ware not output even when -d option was used. - Fix JDBC exception of prepared statement including now() in replication mode (Yugo Nagata) With JDBC, when a prepared statement is executed more than PrepareThreshold times, the statement is named and Describe message is sent after Parse. With named statement, pgpool rewrite now() to parameter in replication mode. Hence, rewritten query has additional parameter than original. In this case, ParameterDescription message sent to frontend (response of Describe) should include OIDs of the same number os original query's parameters. Otherwize, JDBC throws ArrayIndexoutOfBoundsException. This is reported in [pgpool-general-jp: 1192]. - Fix backend error of prepared statement about table which has column whose default value is now() in replication mode (Yugo Nagata) When pgpool parses a named prepared statement with default now(), timestamps are replaced to additional parameters. So, Bind message also should included additional parameter format codes. However, when the number of original parameter was one, pgpool didn't handle this. This caused a error like "incorrect binary data format in bind parameter 2". - doc: Add description about parallel mode doesn't support PREPARE (Yugo Nagata) Per bug #93 =============================================================================== 3.0.14 (umiyameboshi) 2013/12/06 * Version 3.0.14 This is a bugfix release against pgpool-II 3.0.13. __________________________________________________________________ * Bug fixes - Fix incorrect time stamp rewriting in replication mode for certain time zones. (Tatsuo Ishii) Time stamp rewriting calls "SELECT now()" to get current time. Unfortunately the buffer for the current time is too small for certain time zones such as "02:30". Note that non-30-minutes-time-zone such as "0900" does not reveal the problem. This explains why we haven't the bug report until today. Bug reported in [pgpool-general: 2113] and fix provided by Sean Hogan. http://www.sraoss.jp/pipermail/pgpool-general/2013-September/002142.html - Makefile: Replace pg_config by $(PG_CONFIG) in Makefiles so it can be overridden at build time when compiling for different PG major versions. (Tatsuo Ishii) Patch contributed by Christoph Berg ([pgpool-general: 2127]). http://www.sraoss.jp/pipermail/pgpool-general/2013-September/002156.html - configure: Remove -lcompat because it confuses FreeBSD per bug#15. (Tatsuo Ishii) http://www.pgpool.net/mantisbt/view.php?id=15 - Fix segfault when pgpool.conf does not set log_standby_delay. (Tatsuo Ishii) This is caused by wrong initialization for log_standby_delay in pool_config.l.

Per bug #75, patch modified by Tatsuo Ishii. http://www.pgpool.net/mantisbt/view.php?id=75 - Fix error message in read_password_packet(). (Tatsuo Ishii) - Fix memory leak when do_query() fails in timestamp rewriting. (Tatsuo Ishii) For this purpose free_select_result() is changed to accept NULL argument. Per Coverity report "1111454, 1111455 Resource leak". - Fix target node selection logic when "DEALLOCATE portal|statement". (Tatsuo Ishii) When "DEALLOCATE portal|statement" is used and last prepared statement or portal was not found, target node selection map is not set. Probably this is not actually harmful because prepared statement or portal was not found is an error case. The bug was there since day 0. Per Coverity report "1111491 Structurally dead code". - Fix range check bug of MAX_NUM_BACKENDS in corner case. (Tatsuo Ishii) MAX_NUM_BACKENDS is the allowed max number of DB nodes (128, at this point). In reality, probably no one ever tried more than 128 DB nodes and that's the reason why nobody noticed. Per Coverity report "1111429, 1111430 and 1111431 Out-of-bounds write". - Fix that the script forgets to allow public access to pgpool_catalog. (Tatsuo Ishii) The bug prevents inserting data into user tables if pgpool_catalog is created in native replication mode. The bug was there from day 1. I wonder why nobody noticed until today. Per [pgpool-general-jp: 1229]. http://www.sraoss.jp/pipermail/pgpool-general-jp/2013-November/001228.html - Fix uninitialized variable in error case in pool_do_auth(). (Tatsuo Ishii) If there's no valid backend, pgpool will return garbage pid to frontend in auth phase. Actually because no backend is available, frontend will be disconnected later on. So this is not harmless. Per Coverity report "1127331 Uninitialized scalar variable". - Fix to add node id range check when issue an error message using node id. (Tatsuo Ishii) Per Coverity report #1111433 "Out-of-bounds read". - Fix buffer overrun bug and resource leak bug of parse_copy_data(). (Tatsuo Ishii) Per Coverity report 1111427 "Out-of-bounds write" and 1111453 "Resource leak". - Fix possible segfault in CopyDataRaws(). (Tatsuo Ishii) Coverity pointed out that if pool_get_id() returns an error, VALID_BACKEND will access out of array. Per Coverity report 1111413 "Memory - illegal accesses". - Fix strftime() usage in pool_pools(). (Tatsuo Ishii) The buffer is not large enough as expected by the second parameter. This is not harmless because the format string will not produce longer result string than the buffer. Per Coverity report 1111426 "Out-of-bounds access". - Fix resource leak in make_persistent_db_connection. (Tatsuo Ishii) For this purpose, new static function free_persisten_db_connection_memory is added. Per Coverity report #1111468. =============================================================================== 3.0.13 (umiyameboshi) 2013/09/06 * Version 3.0.13 This is a bugfix release against pgpool-II 3.0.12. __________________________________________________________________ * Bug fixes - Fix a mistake in ssh command of doc/basebackup.sh (Tatsuo Ishii) - Fix a bug in parsing prepared statements with transaction handling in replication mode (Tatsuo Ishii) Parse() automatically starts a transaction for non SELECT query to keep consistency among nodes in replication mode. But this wasn't closed. If wrong query comes in, the transaction goes into an abort state but pgpool does not close the transaction. Thus next query causes error because the transaction is still in abort status. This problem was reported in [pgpool-general: 1877] by Sean Hogan. [pgpool-general: 1877] current transaction is aborted, commands ignored http://www.sraoss.jp/pipermail/pgpool-general/2013-July/001905.html - Fix typos of the japanese document (Yugo Nagata) =============================================================================== 3.0.12 (umiyameboshi) 2013/07/10 * Version 3.0.12 This is a bugfix release against pgpool-II 3.0.11. __________________________________________________________________ * Bug fixes - Add mention about "-D" option to the man page. (Tatsuo Ishii) - Consider timeout waiting for completion of failback request in on line recovery (Tatsuo Ishii) This will prevent the situation that recovery operation continues forever and we cannot even shutdown pgpool-II main process. This could happen especially while executing follow master command. - Fix do_query() to not hang when PostgreSQL returns an error (Tatsuo Ishii) The typical symptom is "I see SELECT is keep on running according to pg_stat_activity". To fix this pgpool-II just exits the process and kill the existing connection. This is not gentle but at this point I believe this is the best solution. - Fix bug with do_query which causes hung in extended protocol (Tatsuo Ishii) This problem could occur when insert lock is enabled and pgpool_catalog.insert_lock exists, See [pgpool-general: 1684] for more details. [pgpool-general: 1684] insert_lock hangs http://www.sraoss.jp/pipermail/pgpool-general/2013-May/001711.html - Fix unnecessary degeneration caused by error on commit (Tatsuo Ishii) In master slave mode, if master gets an error at commit, while other slaves are normal at commit, we don't need to degenerate any backend because it is likely that the "kind mismatch error" was caused by a deferred trigger. - Fix to register pgpool_regclass in pg_catalog schema (Tatsuo Ishii) This is necessary to deal with clients which restricts schema search path to pg_catalog only. Postgres_fdw is such a client. - Fix a potential crash in pg_md5 command (Muhammad Usama) - Fix a segmentation fault of a child process that occurs when a startup packet has no PostgreSQL user information (Yugo Nagata) You can reproduce it by $ psql -p 9999 -U '' If enable_pool_hba is on, a child process terminates by segmentation fault. Otherwise if enable_pool_hba is off, the error message is ERROR: pool_discard_cp: cannot get connection pool for user (null) database (null) In both cases, psql terminates with no message on frontend. In the fixed version, if PostgreSQL user is not specified in startup packet, the message as following is output to both log and frontend. This is the same behavior as PostgreSQL. FATAL: no PostgreSQL user name specified in startup packet - Move ssl_ca_cert and ssl_ca_cert_dir descriptions to the SSL section (Yugo Nagata) - Add ssl_ca_cert and ssl_ca_cert_dir descriptions to the japanese document (Yugo Nagata) - Fix to verify the backend node number in pcp_recovery_node (Yugo Nagata) When an invalid number is used, null value is passed as an arguments of recovery script, and this causes a malfunction. In especially, rsync may delete unrelated files in basebackup scripts. - Fix reset query stuck problem. (Tatsuo Ishii) It is reported that reset query (DISCARD ALL etc.) occasionally does not finish and pgpool child remain waiting for reply from backend thus client cannot connect to pgpool. The cause of problem is not identified yet but if client suddenly closes connection to pgpool in the middle of query processing, backend may not accept the reset queries because they are not ready for query. The fix is, if frontend closes connection in unexpected way, query process loop immediately returns with new state: POOL_END_WITH_FRONTEND_ERROR and pgpool closes connection to PostgreSQL then goes back to new connection request waiting loop. Also, pgpool closes connections to backend when client_idle_limit is set and the idle limit. Per bug #107. http://www.pgpool.net/mantisbt/view.php?id=107 =============================================================================== 3.0.11 (umiyameboshi) 2013/04/26 * Version 3.0.11 This is a bugfix release against pgpool-II 3.0.10. __________________________________________________________________ * Buf fixes - Fix to show pool_passwd in "SHOW pool_status". (Yugo Nagata) - Fix long standing bug with timestamp rewriting code for processing extended protocol. (Tatsuo Ishii) Parse() allocate memory using palloc() while rewriting the parse message. Problem is, the rewritten message was kept in the data which is managed by pool_create_sent_message() etc. The function assumes that all the data is in session context memory. However, palloc() allocates memory in query context of course, and gets freed later on when the query context disappears. And the function tries to free the memory as well, which causes various problems, including segfault and double free. To fix this, memory to store rewritten message is allocated using session context. The bug was there since pgpool-II 3.0 was born. Problem analysis and patch contributed by Naoya Anzai.

(Yugo Nagata) When the primary server is behind from standby server, negative value of delay is calculated and the value is assigned to unsigned variable. It causes a log message informing negative replication delay. And what is worse, it also causes SELECT queries to be sent to the primary in load balance even though there are no replication delay in fact. The problem is reported and analyzed by Saitoh Hidenori in [pgpool-genera-jp: 1145].

(Tatsuo Ishii) Even though pgpool_regclass() exists, if pgpool cannot execute the function, the connection to backend hangs. You can reproduce the problem by just dropping the execute privilege from pgpool_regclass and do some insert in native replication mode. The problem is reported in bugtrack #53. #53 pgpool_regclass hangs all connections Date: 2013-04-04 13:35 Reporter: tmandke http://www.pgpool.net/mantisbt/view.php?id=53 - Fix error message mistakes in detect_postmaster_down_error().

(Tatsuo Ishii) The file descriptor to pool_passwd is opened in pgpool main and pgpool child inherits it. When concurrent connections try to authenticate md5 method, they call pool_get_passwd and seek the fd and cause random md5 auth failure because underlying fd is shared. Fix is, let individual pgpool child open the file by calling pool_reopen_passwd_file. Problem reported and analyzed by Jason Slagle in pgpool-general:1141. [pgpool-general: 1141] Possible race condition in pool_get_passwd From: Jason Slagle Date: Sun, 28 Oct 2012 01:12:52 -0400 http://www.sraoss.jp/pipermail/pgpool-general/2012-October/001160.html - Fix pool_send_severity_message() not to use uninitialized memory.

(Tatsuo Ishii) Otherwise reaper() mistakenly ignore some process exit event and make a risk of creating zombie process and forgetting to create new process. Problem reported and fix suggested by Goto in [pgpool-general-jp: 1123]. http://www.sraoss.jp/pipermail/pgpool-general-jp/2012-November/001122.html (in Japanese) - Fix pool_search_relcache() to use MASTER or MASTER_NODE_ID macro, rather than REAL_MASTER_NODE_ID. (Tatsuo Ishii) In case node 0 fail back in streaming replication mode, pgpool does not restart child process. So REAL_MASTER_NODE_ID looks for node 0 con info, which is not present until new connection to backend made. Thus referring to node con info results in segfault. MASTER or MASTER_NODE_ID are safe in this situation because they look at cached former master node id. - Fix long standing bug "portal not found" error when replication delay is too much in streaming replication mode. (Tatsuo Ishii) The bug had been there since the delay threshold was introduced. We changed destination DB node if delay threshold exceeds in bind, describe and execute. However, if parse sends to different node, bind, describe or execute will fail because no parsed statement or portal exists. Solution is, not to send to different parse node even if delay threshold is too much. - Fix pg_md5 to output "\n" after user inputs password. (Yugo Nagata) - Fix child_exit() to not call send_frontend_exits() if there's no connection pool. (Tatsuo Ishii) Otherwise, it segfaults because send_frontend_exits() refers to objects pointed to by pool_connection_pool. Per bug track #44 by tuomas. #44 pgpool went haywire after slave shutdown triggering master failover Reporter: tuomas Date: 2012-12-11 00:33 http://www.pgpool.net/mantisbt/view.php?id=44 - Fix read_startup_packet() to reset alarm and free StartupPacket when pool_read() returns 0 which means incorrect packet length.

(Tatsuo Ishii) If packet length is lower than 0, it should have returned immediately. Otherwise it would cause memory allocation error later on. per pgpool-general:886. Also add canceling alarm. - Add NOTICE message handling to s_do_auth. (Tatsuo Ishii) Without this, health check responses false alarm and causes failover. per bug track: http://www.pgpool.net/mantisbt/view.php?id=25 Also allow to receive ready for query packet *not* right after backend keydata. I'm not sure if this could happen in the real world but the protocol seems to allow this. - Remove unnecessary/confusing debug log from s_do_auth.(Tatsuo Ishii) - Fix infinite loop in SSL mode. When there's pending data in SSL layer of frontend, pool_process_query() checks pending data in backend. (Tatsuo Ishii) If there's non, it loops again and checks frontend/backend receive buffer by using is_cache_empty(). Unfortunately it first checks pending data in SSL layer of frontend, thus goes to backend data and checks again (infinite loop). The solution is, if there's pending data in SSL layer of frontend and query is not in progress, call ProcessFrontendResponse() to process new request from frontend. - Fix is_system_catalog to use pgpool_regclass if available. (Tatsuo Ishii) - Fix memory leak in pool_get_insert_table_name(). (Tatsuo Ishii) If session context's memory contex is used for nodeToString(), memory is not freed until session ends. - Fix possible memory leak in nodeToString(). (Tatsuo Ishii) Since the memory context could be session context, memory used for String object may be considerable if user session continues for hours or days. See bug track #24 for more details. - Fix long standing problem with do_query(). (Tatsuo Ishii) When 1) extended protocol used and 2)unnamed portal is used and 3) no explicit transaction is used, user's unnamed portal is removed by Sync message. This is because Sync message closes transaction and unnamed portal is removed. This leads to "portal "" does not exist" error. Fix is, use "Flush" message instead of Sync. Main difference between using Sync and Flush is, Flush does not return Ready for Query message. So do_query() does not return until all expected responses are returned. It seems the order of messages returned from backend is random, and do_query () manages it by using state bits. =============================================================================== 3.0.8 (umiyameboshi) 2012/08/06 * Version 3.0.8 This is a bugfix release against pgpool-II 3.0.7. __________________________________________________________________ * General - Adopt PostgreSQL 9.2.

(Tatsuo Ishii) - Improve reading and writing pid_file. (Tatsuo Ishii) - Fix pool_process_query() bug reported in [pgpool-general: 672].

Consider following scenario. Suppose node 0 is the initial primary server and 1 is the initial standby server. 1) Node 0 going down and node 1 promotes to new primary. 2) Recover node 0 as new standby. 3) pgpool-II assumes that node 0 is the new primary. This problem happens because pgpool-II regarded unconditionally the youngest node to be the primary. pgpool-II 3.0.3 now checks each node by using pgpool_walrecrunning() to see if it is a actually primary or not and is able to avoid the problem and regards node as standby correctly. Also you can use new variable "%P" to be used in the recovery script. If you do not install the function, the above problem is not resolved. - Fix backend complaining "unexpected EOF on client connection" while doing failover in streaming replication mode(Tatsuo Ishii) - Fix pgpool crashes when all backends go down(Tatsuo Ishii) - Fix replication delay checking so that it does not keep persistent connection to backends.

Patch contributed by Asaf Ohaion(Tatsuo Ishii) =============================================================================== 3.0 (umiyameboshi) 2010/09/10 * Version 3.0 This is the first version of pgpool-II 3.0 series. That is, a "major version up" from 2.2 or 2.3 series. The biggest news is, this version adapts to PostgreSQL 9.0's new feature: Streaming Replication/Hot Standby. Streaming replication can be used as a sub mode of master slave mode. Master slave mode itself heavily enhanced: - SELECTs in explicit transactions can be load balanced - In extended protocol, PARSE/BIND/DESCRIBE messages are sent to the node which execute EXECUTE message, not all node. This will reduce lock contentions. - Auto start of transaction happens only when it needed. - Temporary tables can be used safely. - SELECT which calls functions possibly write to database executes on master(primary) Also many new features are added and major refactoring has been made to the internal structure of pgpool-II. For example, in replication mode, SELECTs calling functions possibly write to database will not allow to load balance. __________________________________________________________________ * New features - Online recovery can be used with master/slave/streaming replication mode(Tatsuo Ishii) - New directive "delay_threshold" is added to monitor replication delay in master/slave/streaming replication mode. If replication delay is too much, SELECTs are not load balanced(Tatsuo Ishii) - show pool_status shows replication delay in master/slave/streaming replication mode(Tatsuo Ishii) - New directive "log_standby_delay" is added to control logging of replication delay in master/slave/streaming replication mode(Tatsuo Ishii) - When insert_lock is enabled and the table includes SERIAL data type, issue row lock on the sequence table. Before we issues table lock. Problem is, the table lock conflicts with auto vacuum and sometimes caused excessive lock waiting(Tatsuo Ishii) - Add support for more "SHOW" commands: pool_nodes, pool_processes, pool_pools, and pool_version(Guillaume Lelarge) - Backend process id and whether frontend connects to this connection pool or not are added to pcp_proc_info's output(Tatsuo Ishii) - "Gracefully detach" option is added to pcp_detach_node. With this option, pcp_detach_node waits until all frontends disconnected(Tatsuo Ishii) - New directive "white_function_list" and "black_function_list" are added to register functions those do not or do write to database(Tatsuo Ishii) - In master/slave mode, SELECTs to system catalogs executes only on master/primary(Tatsuo Ishii) - In master/slave mode, SELECTs to temporary table executes only on master/primary(Tatsuo Ishii) - In master/slave mode, write queries outside of explicit transactions no longer trigger to start internal transaction(Tatsuo Ishii) - In master/slave mode, SELECTs inside explicit transactions are load balanced(Tatsuo, Kitagawa) - In master/slave mode, commands are no longer sent to all DB nodes. This will prevent unnecessary locking(Tatsuo, Kitagawa) - New command option adds to ignore the status file when starting up(Tatsuo Ishii) - Supports PostgreSQL 9.0's new VACUUM syntax(Tatsuo Ishii) - New directive "failover_if_affected_tuples_mismatch" controls the behavior when number of result rows of INSERT/UPDATE/DELETE are differ(Tatsuo Ishii) - When number of result rows of INSERT/UPDATE/DELETE are differ, each number are logged(Tatsuo Ishii) - md5 authentication is supported in replication mode and master/slave mode(Tatsuo Ishii) - Allow to force to move to online recovery second stage even there are connecting frontends(Tatsuo Ishii) - If there's only one DB node and it triggers failover, pgpool-II will automatically connects if the DB node coming up(Tatsuo Ishii) - Pcp commands supports long options(Guillaume Lelarge) - New directive "debug_level" added to control the debug message logging(Tatsuo Ishii) - Allow to use various boolean representations as PostgreSQL in pgpool.conf(Toshihiro Kitagawa) - New C language function pgpool_switch_xlog for online recovery added(Toshihiro Kitagawa) - New C language function pgpool_regclass added to avoid a trouble about handling of duplicate table names in different schema(Tatsuo Ishii) __________________________________________________________________ * Bug fixes - Do not rewrite statement which accesses columns having now() etc. as the default value but the data type are not timestamp etc. Otherwise we have an error in DMLs(Tatsuo Ishii) - Fix timestamp rewriting not to omit schema qualification(Tatsuo Ishii) - Fix bug with timeout handling in pcp commands(Tatsuo Ishii) - Fix SSL hang when large amount of data transferred(Tatsuo Ishii) - Fix failover when there's only one DB node(Tatsuo Ishii) - Fix bug with postmaster start check in online recovery.

(Toshihiro Kitagawa) Note that we need to preserve non-error responses (i.e. ReadyForQuery) and put back them using pool_unread(). Otherwise, ReadyForQuery response of DEALLOCATE. This could happen if PHP PDO used. - Fix SimpleForwardToFrontend() so that it reset select_in_transaction flag and execute_select flag when bind error occurred while executing SELECT. (Toshihiro Kitagawa) - Fix SSL connection sometimes hung if lots of data read from backend. This is caused by the buffering in OpenSSL layer. To fix the problem, (Tatsuo Ishii) we check the buffer has any pending data by using SSL_pending() before calling select(2). See thread [Pgpool-general] Fwd: PGPOOL II 2.3.3 hang in ssl mode for more details. - Fix bug with pcp_check_fd()'s timeout handling. (Tatsuo Ishii) Per erboles. Subject: [Pgpool-general] question about pcp_check_fd Date: Sun, 23 May 2010 18:21:41 -0500 To: pgpool - Do not force replication of DEALLOCATE if operated in master/slave mode. Reported by Jan Kantert.

(Tatsuo Ishii) - Fix long standing bug with timestamp rewriting against array and complex types. (Tatsuo Ishii) Failed examples are: INSERT INTO r1(col[1], col2.foo) VALUES (1, 2); -- insert_column_item UPDATE r1 SET col1[1] = 1, col2.foo = 1; -- set_target PREPARE "p" (int4[]) AS SELECT $1[1]; -- c_expr SELECT (ARRAY[1,2,3])[1]; SELECT (ARRAY[ARRAY[1]])[1][1]; SELECT ('{1,2,3}'::int[])[1]; SELECT ('{1,2,3}'::int[3])[1]; SELECT r1.col[1], (r1.col1).bar, (r1.col1).* FROM r1; -- columnref SELECT (r1.col1).baz[1], (r1.col1).baz[1][2] FROM r1; Patch provided by Akio Ishida. - Fix buffer overrun problem when pcp password is longer than 32. (Tatsuo Ishii) - Fix wait_for_query_response() not to send param status to frontend if frontend is NULL. This could happen while processing reset_query_list. (Tatsuo Ishii) =============================================================================== 2.3.3 (tomiteboshi) 2010/04/23 * Version 2.3.3 This version fixes various bugs since 2.3.2.2. __________________________________________________________________ * Incompatible changes - Please note that this version of pgpool consumes more shared memory than before. If you encounter problems when starting up pgpool, please look into pgpool log. If you find messages something like "could not create shared memory segment: Cannot allocate memory", please increase the shared memory on your system. - Now parallel mode requires replication mode turned on. parallel mode without replication mode turned on has been broken since pgpool-II was born anyway(Toshihiro Kitagawa) - Change default value for insert_lock to false since there's no point in turning this on in master/slave mode. Fix suggested by Fujii Masao(Tatsuo Ishii) __________________________________________________________________ * Newly added documents - README.online-recovery, which is an internal document of online recovery, added(Tatsuo Ishii) __________________________________________________________________ * Bug fixes - Fix long standing bug since pgpool-II 1.0 which causes segfault of pgpool child process. This was caused by miscalculation of shmem size in pgpool parent. Bug analysis by Kitagawa patch created by Tatsuo - Add restriction for parallel mode(Toshihiro Kitagawa) - The Natural Join is not supported - The USING CLAUSE is converted to ON CLAUSE by query rewrite process - Fix possible crash during rewriting JOIN syntax that have USING in parallel query mode(Toshihiro Kitagawa) This fix is supporting such as following JOIN syntax. example: - SELECT * FROM a JOIN b USING (aid) JOIN c USING (cid); - SELECT * FROM a JOIN b USING (aid) JOIN c USING (cid) JOIN d USING (did) - Fix parallel query so that it can parse INSERT statements that have current_time before a partitioning key column (Toshihiro Kitagawa) - Fix SimpleForwardToBackend() so that pgpool doesn't keep waiting for reply from a backend, when clients using the extended query protocol cause a command error such as bind error. This bug occur in master/slave, raw, and connection pool mode. This fix is, sending SYNC message to recover error after command error(Toshihiro Kitagawa) - Fix SIGINT/SIGQUIT is ignored if pgpool child is in select(). In this case pgpool retries select() thus the signal is ignored(Tatsuo Ishii) - Fix connect_inet_domain_socket_by_port/ connect_unix_domain_socket_by_port so that they check if SIGTERM/SIGINT/SIGQUIT signal has been delivered. Per bug report from Daniel Codina(Tatsuo Ishii) - Fix possible crash during creating "kind mismatch" error message. This used to work but was broken in 2.3.2(Tatsuo Ishii) - Fix bug with health checking. If a network problem such as unplugged wire happens while calling connect(), health checking does not work since connect_unix_domain_socket()/connect_inet_domain_socket() do retry if connect() is interrupted by ALARM signal. Added new retry argument which controls the retrying behavior to those functions. Per bug report and problem analysis by Daniel Codina(Tatsuo Ishii) - Fix enbug in 2.3.2.2 with time stamp rewriting in SimpleForwardToBackend. Per bug report from Bugtrack #1010771. Report from Peter Pramberge(Tatsuo Ishii) - Fix rewriting "*" in parallel query. Patch contributed by sho-san(Toshihiro Kitagawa) - Fix connect_inet_domain_socket_by_port() so that it print out error message by using hstrerror(), rather than strerror()(Tatsuo Ishii) =============================================================================== 2.3.2.2 (tomiteboshi) 2010/02/22 * Version 2.3.2.2 This version fixes various bug in 2.3.x. - When rewriting timestamp in extended query, it allocated less than what it actually needed. This causes random problematic behavior, typically "message: invalid string in message" error in backend(Tatsuo Ishii). - In extended query, if one of parameters contains NULL, ppool crashes(Tatsuo Ishii). - If in previous status file all nodes were marked down status, it is regarded that this file is bogus. This will prevent "all node down" syndrome(Tatsuo Ishii). =============================================================================== 2.3.2.1 (tomiteboshi) 2010/02/11 * Version 2.3.2.1 This version fixes bug in 2.3.x. It is identified that pgpool-II 2.3.x has a problem with erroneous query processing(Akio Ishida). =============================================================================== 2.3.2 (tomiteboshi) 2010/02/07 * Version 2.3.2 This version includes various fixes for bugs in 2.3.1 or before. All 2.3.x users are encouraged to upgrade to 2.3.2 as soon as possible. Also this version enables long awaited SSL support and large object replication support. __________________________________________________________________ * Enhancements - SSL support(Sean Finney) - Large object replication support. You need PostgreSQL 8.1 or later, however(Tatsuo Ishii) - Emit statement log when error or notice message comes from query parsing process. This is useful because PostgreSQL does not log particular statement if the error was detected *before* raw parser get executed. This typically happens when encoding error was found(Tatsuo Ishii) - Display original query to log if kind mismatch error was caused by DEALLOCATE(Tatsuo Ishii) - While health checking and recovery use postgres database if possible. If postgres database does not exist, use template1 as it stands now. While connecting template1, certain commands, for example DROP DATABASE cannot used. Using postgres database allows to use these commands while recovery(Tatsuo Ishii) __________________________________________________________________ * Bug fixes - Fix errors in timestamp rewriting which occasionally cause broken packet sentto slave nodes(Tatsuo Ishii) - Fix errors when timestamp rewriting is used with V2 protocol(Toshihiro Kitagawa) - Propagate Bind, Describe and Close messages to only master node if running in master/slave and in transaction (Tatsuo Ishii) - Fix do_child() so that check_stop_request() exits immediately when smart shutdown signal has been sent. This has been used to work in 2.2(Toshihiro Kitagawa) - Fix ProcessFrontendResponse not to accept invalid frontend packet(Xavier Noguer) - Use %dz for sizeof in fprintf for more portability(Tatsuo Ishii) - Fix compiler warnings(Tatsuo Ishii) - Do not force replication of DEALLOCATE if operated in master/slave mode. Now that pgpool do not execute PARSE in all nodes, this was pointless and caused problem (kind mismatch when executing DEALLOCATE)(Tatsuo Ishii) =============================================================================== 2.3.1 (tomiteboshi) 2009/12/18 * Version 2.3.1 This version includes various fixes for bugs in 2.3 or before. All 2.3 users are encouraged to upgrade to 2.3.1 as soon as possible. __________________________________________________________________ * Bug fixes - If all of following conditions met, incorrect data is written to DB(Tatsuo Ishii) - pgpool is running in replication mode - pgpool is running on 64bit OS - INSERT or UPDATE are used which explicitly include now(), - CURRENT_TIMESTAMP, CURRENT_DATE, CURRENT_TIME. Or the target - Table's default value use above functions - The SQL statement includes out of 32bit integer value(-2147483648 to 2147483647 in decimal) Example SQL: INSERT INTO t1(id, regdate) VALUES(98887776655, NOW()); - Fix crush in case of more than 18 DB nodes are used(Tatsuo Ishii) - Enhance kind mismatch error message. If kind is ERROR or NOTICE, the error or notice message from PostgreSQL will be printed (Tatsuo Ishii) =============================================================================== 2.3 (tomiteboshi) 2009/12/07 * Version 2.3 This version enhances replication, especially CURRENT_TIMESTAMP, CURRENT_DATE, now() etc. now can be properly replicated. Also performance of replication when num_init_children == 1 is enhanced. Pgpool-II now records the status of down nodes, and remember when it restarts to ensure that keep the node status as before. Also some logs are enhanced and more fine fail over controls are added. Please note that pgpool-II 2.3 includes all of enhancements and fixes of pgpool-II 2.2.1 to 2.2.6. __________________________________________________________________ * Incompatibilities from 2.2.x - pgpool_status file is created under logdir. So you need to give write permission to the directory so that pgpool-II can read/write pgpool_status file. __________________________________________________________________ * Enhancements - Enable proper replication of results of temporal functions (CURRENT_TIMESTAMP, CURRENT_DATE, now() etc.). Now applications can execute INSERT/UPDATE tables which include default values using those temporal functions. There are small limitations. See restriction sections of docs for more details (Akio Ishida) - Use PostgreSQL 8.4's SQL parser(Akio Ishida) - Enhance the performance 20% to 100% of replication when num_init_children == 1(Tatsuo Ishii) - Add new directive log_per_node_statement which is similar to log_statement except that prints info for each DB node to make it easier which query is sent to which DB node(Tatsuo Ishii) - Add new directive fail_over_on_backend_error to control the behavior of fail over(Tatsuo Ishii) - Record DB node status and remember when pgpool-II restarts(Tatsuo Ishii) - EXPLAIN and EXPLAIN ANALYZE for SELECT query are now load balanced. This will prevent unwanted kind mismatch errors when EXPLAIN produces slightly different plan(Tatsuo Ishii) - Enhance CSS of pgpool-ja.html(Tatsuo Ishii) - Add sample configuration file for replication mode and master/slave mode(Tatsuo Ishii) - Add test for temporal data(Akio Ishida) =============================================================================== 2.2 Series (2009/02/08 - 2012/08/06) =============================================================================== 2.2.8 (urukiboshi) 2012/08/06 * Version 2.2.8 It includes various fixes for bugs various bug fixes in 2.2.7. __________________________________________________________________ * Bug fixes - Fix do_error_execute_command() so that it discards responses from backend until ErrorResponse received.

Also it allows to use temp tables in master/slave mode. It includes various fixes for bugs in 2.2.5 or before as usual. __________________________________________________________________ * Bug fixes - Do not allow to load balance DECLARE, CLOSE, FETCH and MOVE. If data gets updated and CLOSE issued after transaction commit(i.e. holdbale cursor), this will cause data inconsistency since CLOSE is executed one of the severs, rather than all(Tatsuo Ishii) - In master/slave mode, execute Parse message on only master node. In previous versions Parse executed on all nodes, which grabbed unnecessary lock(Tatsuo Ishii) - Remove init script from all runlevels before uninstall(Devrim) - Fix pgpool.spec(Devrim) - Do not execute REINDEX DATABASE or SYSTEM, CREATE/DROP TABLE SPACE inside a transaction block(Tatsuo Ishii) __________________________________________________________________ * Enhancements - Allow to change weight by reloading pgpool.conf.

Load balance control variables may remain not be restored and subsequent DML/DDL call might sent to only master node(Tatsuo Ishii) - Send NOTICE message to frontend periodically if V2 protocol is used. This is ifdef out since it affects visible change to applications. 2.2.3 unconditionally sends param packet to client even it uses version 2 protocol, which is apparently wrong. Also tweak checking period from 1 second to 30 seconds since 1 second seems too aggressive(Tatsuo Ishii) - Block signals before forking children rather after. Otherwise parent will be killed by failover signal if it receives a signal before establishing signal handler(Tatsuo Ishii) - Remove unnecessary spaces and tabs at the end of line(Jun Kuriyama) =============================================================================== 2.2.3 (urukiboshi) 2009/8/11 * Version 2.2.3 This version fixes various bugs in 2.2.2 or before. __________________________________________________________________ * Bug fixes - Fix child process death if one of backends is not available(Tatsuo Ishii). - Fix various parallel query bugs(Yoshiharu Mori) - Fix message corruption for kid mismatch error(Akio Ishida) - Now statement_time works(Tatsuo Ishii) - Enhance health checking to detect postmaster stopping by SIGSTOP(Tatsuo Ishii) - Detect frontend abnormal exiting while waiting for reply from backend.

Please note that an important fix is made to avoid data inconsistency risk, which could happen when client does not exit gracefully(without sending "X" packet) while pgpool is trying to send data to it. This could happen with all version of pgpool-II. __________________________________________________________________ * Bug fixes - Ignore write error on frontend connection. This is needed to continue processing with backend, otherwise we risk data inconsistency(Tatsuo Ishii) - Fix bug introduced in 2.2.1 (In master slave mode, sometimes DEALLOCATE fails). If prepared statement reused, pgpool hangs(Toshihiro Kitagawa) - Fix pgpool crash when SQL command PREPARE and protocol level EXECUTE are mixed.

Also an important bug, serializable transactions could cause data inconsistency among DB nodes, is fixed. Query cancelation, which never worked since pgpool-II was born, is finally fixed. __________________________________________________________________ * New features/enhancements - With insert_lock, now a table is locked only if it has SERIAL data type and now the default value for insert_lock is true(Tatsuo Ishii) - Start internal transaction other than INSERT, UPDATE, DELETE and SELECT to keep node consistency(Tatsuo Ishii) - Add client_idle_limit_in_recovery directive. This will prevent 2nd stage of on line recovery from not going forward by idle clients sitting forever(Tatsuo Ishii) - Add pid_file_name directive which specifies a path to the file containing pgpool process id. "logdir" is no more used(Tatsuo Ishii) - Allow to load balance DECLARE, FETCH and CLOSE(Tatsuo Ishii) - Add -d option to pcp commands(Jun Kuriyama) - Enhance kind mismatch error message to include original query string(Tatsuo Ishii) __________________________________________________________________ * Bug fixes - Close all file descriptors when running in daemon mode. Otherwise we inherit sockets from apache when it's started by pgpoolAdmin. This results in that port 80 is occupied for example. Patch provided by Akio Ishida. Also add chdir("/"). This is always good for daemon programs(Tatsuo Ishii) - Allow MD5 authentication in raw mode as stated in docs(Tatsuo Ishii) - Check transaction serialization failure error in serializable mode and abort all nodes if so. Otherwise we allow data inconsistency among DB nodes(Tatsuo Ishii). See following scenario: (M:master, S:slave) M:S1:BEGIN; M:S2:BEGIN; S:S1:BEGIN; S:S2:BEGIN; M:S1:SET TRANSACTION ISOLATION LEVEL SERIALIZABLE; M:S2:SET TRANSACTION ISOLATION LEVEL SERIALIZABLE; S:S1:SET TRANSACTION ISOLATION LEVEL SERIALIZABLE; S:S2:SET TRANSACTION ISOLATION LEVEL SERIALIZABLE; M:S1:UPDATE t1 SET i = i + 1; S:S1:UPDATE t1 SET i = i + 1; M:S2:UPDATE t1 SET i = i + 1; <-- blocked S:S1:COMMIT; M:S1:COMMIT; M:S2:ERROR: could not serialize access due to concurrent update S:S2:UPDATE t1 SET i = i + 1; <-- success in UPDATE and data becomes inconsistent! - avoid kind mismatch error caused by "SET TRANSACTION ISOLATION LEVEL must be called before any query"(Tatsuo Ishii). This could happen in following scenario: M:S1:BEGIN; S:S1:BEGIN; M:S1:SELECT 1; <-- only sent to MASTER M:S1:SET TRANSACTION ISOLATION LEVEL SERIALIZABLE; S:S1:SET TRANSACTION ISOLATION LEVEL SERIALIZABLE; M: <-- error S: <-- ok since no previous SELECT is sent. kind mismatch error occurs! - Process status display has extra space on FreeBSD(Jun Kuriyama) - Fix incorrect kind mismatch detection case. e.g: BEGIN; BEGIN; (Tatsuo Ishii) - If PostgreSQL sends lots of DEBUG message, sometimes pgpool complains: 2008-11-08 22:41:53 ERROR: pid 23744: do_command: backend does not return ReadyForQuery. This due to a wrong assumption for the client/server protocol(Tatsuo Ishii) - Fix the case when sending an erroneous query to abort transaction. It assumed that after sending an error query, always ReadyForQuery came right after that. If some debugging or logging verboseness is set, PostgreSQL might sends NOTICE before ReadyForQuery(Tatsuo Ishii) - Query cancelation now works. It never worked since pgpool-II was born(Tatsuo Ishii) - Fix online recovery to wait for failback done before allowing to accept connections from clients. It was supposed to work like this but actually was not since the day 0 when online recovery was born. Without the fix there could be potential data inconsistency among DB nodes(Tatsuo Ishii) - Fix pgpool-II crash after on line recovery. This happens after the failback process adds a recovered node which has no connection to the node(Tatsuo Ishii) - Fix pgpool-II errors when postgresql.conf is reloaded. This was caused by parameter status packet sent asynchronously from backend, which indicates the internal setting of backend has been changed(Tatsuo Ishii) __________________________________________________________________ * Incompatible changes - Always fail over and restart all children. Before we do restart only if master has not been changed. This is wrong. If we have trouble with network cable or something, TCP/IP stack keeps on retrying for long time and the only way to prevent it is restarting process(Tatsuo Ishii) - "logdir" is no more used. Instead use "pid_file_name"(Tatsuo Ishii) - Default value for insert_lock is now true(Tatsuo Ishii) =============================================================================== 2.1 Series (2008/07/25 - 2008/07/25) =============================================================================== 2.1 (inamiboshi) 2008/7/25 * Version 2.1 __________________________________________________________________ * New feature - Add '%m' format to failover_command and failback_command to obtain new master node ID.

You can embed shell variables for delayed # expansion at the time the message is displayed, but you will need to # quote other shell meta-characters carefully to prevent them being # expanded when the contents are evaled. usage='$progpath [OPTION]...' # Short help message in response to '-h' and '--help'.

The client * should send an empty string as the username. * * - If the password isn't valid UTF-8, or contains characters prohibited * by the SASLprep profile, we skip the SASLprep pre-processing and use * the raw bytes in calculating the hash. * * - Channel binding is not supported yet. * * * The password stored in pg_authid consists of the iteration count, salt, * StoredKey and ServerKey. * * SASLprep usage * -------------- * * One notable difference to the SCRAM specification is that while the * specification dictates that the password is in UTF-8, and prohibits * certain characters, we are more lenient. If the password isn't a valid * UTF-8 string, or contains prohibited characters, the raw bytes are used * to calculate the hash instead, without SASLprep processing. This is * because PostgreSQL supports other encodings too, and the encoding being * used during authentication is undefined (client_encoding isn't set until * after authentication). In effect, we try to interpret the password as * UTF-8 and apply SASLprep processing, but if it looks invalid, we assume * that it's in some other encoding. * * In the worst case, we misinterpret a password that's in a different * encoding as being Unicode, because it happens to consists entirely of * valid UTF-8 bytes, and we apply Unicode normalization to it. As long * as we do that consistently, that will not lead to failed logins. * Fortunately, the UTF-8 byte sequences that are ignored by SASLprep * don't correspond to any commonly used characters in any of the other * supported encodings, so it should not lead to any significant loss in * entropy, even if the normalization is incorrectly applied to a * non-UTF-8 password. * * Error handling * -------------- * * Don't reveal user information to an unauthenticated client. We don't * want an attacker to be able to probe whether a particular username is * valid. In SCRAM, the server has to read the salt and iteration count * from the user's password verifier, and send it to the client. To avoid * revealing whether a user exists, when the client tries to authenticate * with a username that doesn't exist, or doesn't have a valid SCRAM * verifier in pg_authid, we create a fake salt and iteration count * on-the-fly, and proceed with the authentication with that. In the end, * we'll reject the attempt, as if an incorrect password was given. When * we are performing a "mock" authentication, the 'doomed' flag in * scram_state is set. * * In the error messages, avoid printing strings from the client, unless * you check that they are pure ASCII. We don't want an unauthenticated * attacker to be able to spam the logs with characters that are not valid * to the encoding being used, whatever that is. We cannot avoid that in * general, after logging in, but let's do what we can here. * * * Portions Copyright (c) 1996-2017, PostgreSQL Global Development Group * Portions Copyright (c) 1994, Regents of the University of California * * src/backend/libpq/auth-scram.c * *------------------------------------------------------------------------- */ #include #include #include #include "pool.h" #include "auth/scram-common.h" #include "utils/sha2.h" #include "auth/pool_passwd.h" #include "auth/scram.h" #include "auth/pool_auth.h" #include "utils/base64.h" #include "utils/elog.h" #include "utils/palloc.h" #include "utils/memutils.h" #include "parser/stringinfo.h" #include "utils/palloc.h" #include "utils/elog.h" #include "utils/memutils.h" #define MOCK_AUTH_NONCE_LEN 32 typedef enum { FE_SCRAM_INIT, FE_SCRAM_NONCE_SENT, FE_SCRAM_PROOF_SENT, FE_SCRAM_FINISHED } fe_scram_state_enum; typedef struct { fe_scram_state_enum state; /* These are supplied by the user */ const char *username; char *password; /* We construct these */ uint8 SaltedPassword[SCRAM_KEY_LEN]; char *client_nonce; char *client_first_message_bare; char *client_final_message_without_proof; /* These come from the server-first message */ char *server_first_message; char *salt; int saltlen; int iterations; char *nonce; /* These come from the server-final message */ char *server_final_message; char ServerSignature[SCRAM_KEY_LEN]; } fe_scram_state; /* * Status data for a SCRAM authentication exchange.

Refer to chapter "Client Authentication" for a # complete description. A short synopsis follows. # # This file controls: which hosts are allowed to connect, how clients # are authenticated, which user names they can use, which databases they # can access. Records take one of these forms: # # local DATABASE USER METHOD [OPTION] # host DATABASE USER ADDRESS METHOD [OPTIONS] # hostssl DATABASE USER ADDRESS METHOD [OPTIONS] # hostnossl DATABASE USER ADDRESS METHOD [OPTIONS] # # (The uppercase items must be replaced by actual values.) # # The first field is the connection type: "local" is a Unix-domain # socket, "host" is either a plain or SSL-encrypted TCP/IP socket. # "hostssl" is an SSL-encrypted TCP/IP socket, and "hostnossl" is a # plain TCP/IP socket. # # DATABASE can be "all", "sameuser", a database name, or a comma-separated # list thereof. Note that "samegroup" like in PostgreSQL's pg_hba.conf # file is not supported, since pgpool does not know which group a user # belongs to. Also note that the database specified here may not exist in # the backend PostgreSQL. pgpool will authenticate based on the database's # name, not based on whether it exists or not. # # USER can be "all", a user name, or a comma-separated list thereof. In # both the DATABASE and USER fields you can also write a file name prefixed # with "@" to include names from a separate file. Note that a group name # prefixed with "+" like in PostgreSQL's pg_hba.conf file is not supported # because of the same reason as "samegroup" token. Also note that a user # name specified here may not exist in the backend PostgreSQL. pgpool will # authenticate based on the user's name, not based on whether he/she exists. # # CIDR-ADDRESS specifies the set of hosts the record matches. # It is made up of an IP address and a CIDR mask that is an integer # (between 0 and 32 (IPv4) that specifies the number of significant bits in # the mask. Alternatively, you can write an IP address and netmask in # separate columns to specify the set of hosts. # # METHOD can be "trust", "reject", "md5" , "scram-sha-256" or "pam". # Note that "pam" sends passwords in clear text. # # OPTION is the name of the PAM service. Default service name is "pgpool" # # Database and user names containing spaces, commas, quotes and other special # characters must be quoted. Quoting one of the keywords "all" or "sameuser" # makes the name lose its special character, and just match a database or # username with that name. # # This file is read on pgpool startup. If you edit the file on a running # system, you have to restart the pgpool for the changes to take effect. # Put your actual configuration here # ---------------------------------- # # If you want to allow non-local connections, you need to add more # "host" records. In that case you will also need to make pgpool listen # on a non-local interface via the listen_addresses configuration parameter. # # TYPE DATABASE USER CIDR-ADDRESS METHOD # "local" is for Unix domain socket connections only local all all trust # IPv4 local connections: host all all 127.0.0.1/32 trust host all all ::1/128 trust pgpool-II-4.6.1/src/sample/pcp.conf.sample0000644000175000017500000000153215010601345015217 00000000000000# PCP Client Authentication Configuration File # ============================================ # # This file contains user ID and his password for pgpool # communication manager authentication. # # Note that users defined here do not need to be PostgreSQL # users.

To execute regress.sh you need to install: - pgpool_setup - PostgreSQL 8.3 or later (requires EXTENSION) - pgbench - perl PostgreSQL interface - other tools or libraries required in each test cases regress.sh: the regression test driver. To execute the test, type "sh regress.sh". To get the lists of arguments accepted by regress.sh type "sh regress.sh -?" clean.sh: remove files including PostgreSQL DB clusters created by regress.sh. tests: test scripts live here. Each test case has its own subdirectory. In the directory the test script resides and the script name must be "test.sh". The script should return exit code 0 upon successful completion of the test. Otherwise it should return non 0 value. To add a new test case, simply create a shell script under this. The test name "001.*" to "050.*" is for regular regression tests, while after "051.*" are for bugs. regress.sh exports following environment variables which can be used by test scripts. PGPOOL_SETUP file path of pgpool_setup file PGPOOL_INSTALL_DIR pgpool-II installed directory PGBIN directory path containing PostgreSQL binaries JDBC_DRIVER file path of JDBC driver log: any output of the test files above is created under the directory. The log file name is same as the test name. libs.sh: contains some useful bash functions.

Refer to chapter "Client Authentication" for a # complete description. A short synopsis follows. # # This file controls: which hosts are allowed to connect, how clients # are authenticated, which user names they can use, which databases they # can access. Records take one of these forms: # # local DATABASE USER METHOD [OPTION] # host DATABASE USER CIDR-ADDRESS METHOD [OPTION] # # (The uppercase items must be replaced by actual values.) # # The first field is the connection type: "local" is a Unix-domain # socket, "host" is either a plain or SSL-encrypted TCP/IP socket. # # DATABASE can be "all", "sameuser", a database name, or a comma-separated # list thereof. Note that "samegroup" like in PostgreSQL's pg_hba.conf # file is not supported, since pgpool does not know which group a user # belongs to. Also note that the database specified here may not exist in # the backend PostgreSQL. pgpool will authenticate based on the database's # name, not based on whether it exists or not. # # USER can be "all", a user name, or a comma-separated list thereof. In # both the DATABASE and USER fields you can also write a file name prefixed # with "@" to include names from a separate file. Note that a group name # prefixed with "+" like in PostgreSQL's pg_hba.conf file is not supported # because of the same reason as "samegroup" token. Also note that a user # name specified here may not exist in the backend PostgreSQL. pgpool will # authenticate based on the user's name, not based on whether he/she exists. # # CIDR-ADDRESS specifies the set of hosts the record matches. # It is made up of an IP address and a CIDR mask that is an integer # (between 0 and 32 (IPv4) that specifies the number of significant bits in # the mask. Alternatively, you can write an IP address and netmask in # separate columns to specify the set of hosts. # # METHOD can be "trust", "reject", "md5" , "scram-sha-256" or "pam". # Note that "pam" sends passwords in clear text. # # OPTION is the name of the PAM service. Default service name is "pgpool" # # Database and user names containing spaces, commas, quotes and other special # characters must be quoted. Quoting one of the keywords "all" or "sameuser" # makes the name lose its special character, and just match a database or # username with that name. # # This file is read on pgpool startup. If you edit the file on a running # system, you have to restart the pgpool for the changes to take effect. # Put your actual configuration here # ---------------------------------- # # If you want to allow non-local connections, you need to add more # "host" records. In that case you will also need to make pgpool listen # on a non-local interface via the listen_addresses configuration parameter. # # TYPE DATABASE USER CIDR-ADDRESS METHOD # "local" is for Unix domain socket connections only local all all trust # IPv4 local connections: host all md5_user 127.0.0.1/32 scram-sha-256 host all md5_user ::1/128 scram-sha-256 host all scram_user 127.0.0.1/32 md5 host all scram_user ::1/128 md5 pgpool-II-4.6.1/src/test/regression/tests/022.pool_passwd_alternative_auth/test.sh0000755000175000017500000000706715010601345025130 00000000000000#!/usr/bin/env bash #------------------------------------------------------------------- # test script for scram and md5 authentication # where password is stored in pool_passwd file and # frontend uses different auth from backends # # This test is only valid with PostgreSQL 10 or later. if [ $PGVERSION -le 9 ];then exit 0 fi source $TESTLIBS TESTDIR=testdir PSQL=$PGBIN/psql CREATEUSER=$PGBIN/createuser rm -fr $TESTDIR mkdir $TESTDIR cd $TESTDIR # create test environment echo -n "creating test environment..." $PGPOOL_SETUP -m s -n 2 || exit 1 echo "done." source ./bashrc.ports #echo "enable_pool_hba = on" >> etc/pgpool.conf echo "allow_clear_text_frontend_auth = off" >> etc/pgpool.conf #set max_init_children to 1 to make sure we reuse the #connection to test wrong password rejection echo "num_init_children = 1" >> etc/pgpool.conf echo "enable_pool_hba = on" >> etc/pgpool.conf #create pool_passwd file echo "scram_user:scram_password" >> etc/pool_passwd echo "md5_user:md5_password" >> etc/pool_passwd #copy the pool_hba to etc dir cp ../pool_hba.conf etc/ ./startall export PGPORT=$PGPOOL_PORT wait_for_pgpool_startup #set passwords $PSQL -c "SET password_encryption = 'scram-sha-256';

Refer to chapter "Client Authentication" for a # complete description. A short synopsis follows. # # This file controls: which hosts are allowed to connect, how clients # are authenticated, which user names they can use, which databases they # can access. Records take one of these forms: # # local DATABASE USER METHOD [OPTION] # host DATABASE USER CIDR-ADDRESS METHOD [OPTION] # # (The uppercase items must be replaced by actual values.) # # The first field is the connection type: "local" is a Unix-domain # socket, "host" is either a plain or SSL-encrypted TCP/IP socket. # # DATABASE can be "all", "sameuser", a database name, or a comma-separated # list thereof. Note that "samegroup" like in PostgreSQL's pg_hba.conf # file is not supported, since pgpool does not know which group a user # belongs to. Also note that the database specified here may not exist in # the backend PostgreSQL. pgpool will authenticate based on the database's # name, not based on whether it exists or not. # # USER can be "all", a user name, or a comma-separated list thereof. In # both the DATABASE and USER fields you can also write a file name prefixed # with "@" to include names from a separate file. Note that a group name # prefixed with "+" like in PostgreSQL's pg_hba.conf file is not supported # because of the same reason as "samegroup" token. Also note that a user # name specified here may not exist in the backend PostgreSQL. pgpool will # authenticate based on the user's name, not based on whether he/she exists. # # CIDR-ADDRESS specifies the set of hosts the record matches. # It is made up of an IP address and a CIDR mask that is an integer # (between 0 and 32 (IPv4) that specifies the number of significant bits in # the mask. Alternatively, you can write an IP address and netmask in # separate columns to specify the set of hosts. # # METHOD can be "trust", "reject", "md5" , "scram-sha-256" or "pam". # Note that "pam" sends passwords in clear text. # # OPTION is the name of the PAM service. Default service name is "pgpool" # # Database and user names containing spaces, commas, quotes and other special # characters must be quoted. Quoting one of the keywords "all" or "sameuser" # makes the name lose its special character, and just match a database or # username with that name. # # This file is read on pgpool startup.

Also, it's important to keep in mind that this code may * get called from within an aborted transaction, in which case operations * such as syscache lookups are unsafe. * * Some notes about recursion and errors during error processing: * * We need to be robust about recursive-error scenarios --- for example, * if we run out of memory, it's important to be able to report that fact. * There are a number of considerations that go into this. * * First, distinguish between re-entrant use and actual recursion. It * is possible for an error or warning message to be emitted while the * parameters for an error message are being computed. In this case * errstart has been called for the outer message, and some field values * may have already been saved, but we are not actually recursing. We handle * this by providing a (small) stack of ErrorData records. The inner message * can be computed and sent without disturbing the state of the outer message. * (If the inner message is actually an error, this isn't very interesting * because control won't come back to the outer message generator ... but * if the inner message is only debug or log data, this is critical.) * * Second, actual recursion will occur if an error is reported by one of * the elog.c routines or something they call. By far the most probable * scenario of this sort is "out of memory"; and it's also the nastiest * to handle because we'd likely also run out of memory while trying to * report this error!

We fill in all of the type-independent MemoryContext fields. * 4. We call the type-specific init routine (using the methods pointer). * The init routine is required to make the node minimally valid * with zero chance of failure --- it can't allocate more memory, * for example. * 5. Now we have a minimally valid node that can behave correctly * when told to reset or delete itself. We link the node to its * parent (if any), making the node part of the context tree. * 6.

This routine can now do things * that might fail (like allocate more memory), so long as it's * sure the node is left in a state that delete will handle. * * This protocol doesn't prevent us from leaking memory if step 6 fails * during creation of a top-level context, since there's no parent link * in that case. However, if you run out of memory while you're building * a top-level context, you might as well go home anyway... * * Normally, the context node and the name are allocated from * TopMemoryContext (NOT from the parent context, since the node must * survive resets of its parent context!). However, this routine is itself * used to create TopMemoryContext! If we see that TopMemoryContext is NULL, * we assume we are creating TopMemoryContext and use malloc() to allocate * the node. * * Note that the name field of a MemoryContext does not point to * separately-allocated storage, so it should not be freed at context * deletion. *-------------------- */ MemoryContext MemoryContextCreate(NodeTag tag, Size size, MemoryContextMethods *methods, MemoryContext parent, const char *name) { MemoryContext node;

This will use gram_template.y file and will generate two grammar files. gram_minimal.y (for the minimal parser) and gram.y (for the standard parser). 'make generate_parsers' uses sunifdef (http://www.linuxcertif.com/man/1/sunifdef/) utility to generate the parsers. And If the 'sunifdef' utility is present on the the system in the standard path then the configure will automatically pick it up by itself. But in the case when the sunifdef is not present in the default path then you can use "--with-sunifdef=sunifdef_dir' configure switch to provide the 'sunifdef' path. Notes on importing the PostgreSQL parser ---------------------------------------- To import the PostgreSQL parser, merge all the changes in gram_template.y file from PostgreSQL's gram.y, and then run 'make generate_parsers' to generate updated minimal and standard grammar files for Pgpool-II Controlling minimal and standard parser output ----------------------------------------------- All the code in gram_template.y file inside #ifdef pgpool_minimal_parser section will only gets included in the gram_minimal.y file while the code inside #ifndef pgpool_minimal_parser section will only be included in the standard parser file. Similarly, the unconditional code which is not in either #ifndef pgpool_minimal_parser or #ifdef pgpool_minimal_parser will become part of both the parser. Example:1 --------- #ifdef pgpool_minimal_parser code only for the minimal parser #else code only for the standard parser #endif code for both parsers .. Example:2 --------- #ifndef pgpool_minimal_parser code only for the standard parser #else code only for the minimal parser #endif code for both parsers pgpool-II-4.6.1/src/parser/gram.c0000644000175000017500001325122715010606503013430 00000000000000/* A Bison parser, made by GNU Bison 3.7.4. */ /* Bison implementation for Yacc-like parsers in C Copyright (C) 1984, 1989-1990, 2000-2015, 2018-2020 Free Software Foundation, Inc.

If you do * database accesses, your code will fail when we have aborted the * current transaction and are just parsing commands to find the next * ROLLBACK or COMMIT. If you make use of SET variables, then you * will do the wrong thing in multi-query strings like this: * SET constraint_exclusion TO off; SELECT * FROM foo; * because the entire string is parsed by gram.y before the SET gets * executed. Anything that depends on the database or changeable state * should be handled during parse analysis so that it happens at the * right time not the wrong time. * * WARNINGS * If you use a list, make sure the datum is a node so that the printing * routines work. * * Sometimes we assign constants to makeStrings.

While that's not really necessary since * we removed postfix operators, we continue to do so because it provides a * reference point for a precedence level that we can assign to other * keywords that lack a natural precedence level. * * We need to do this for PARTITION, RANGE, ROWS, and GROUPS to support * opt_existing_window_name (see comment there). * * The frame_bound productions UNBOUNDED PRECEDING and UNBOUNDED FOLLOWING * are even messier: since UNBOUNDED is an unreserved keyword (per spec!), * there is no principled way to distinguish these from the productions * a_expr PRECEDING/FOLLOWING. We hack this up by giving UNBOUNDED slightly * lower precedence than PRECEDING and FOLLOWING. At present this doesn't * appear to cause UNBOUNDED to be treated differently from other unreserved * keywords anywhere else in the grammar, but it's definitely risky. We can * blame any funny behavior of UNBOUNDED on the SQL standard, though. * * To support CUBE and ROLLUP in GROUP BY without reserving them, we give them * an explicit priority lower than '(', so that a rule with CUBE '(' will shift * rather than reducing a conflicting rule that takes CUBE as a function name. * Using the same precedence as IDENT seems right for the reasons given above. * * SET is likewise assigned the same precedence as IDENT, to support the * relation_expr_opt_alias production (see comment there). * * KEYS, OBJECT_P, SCALAR, VALUE_P, WITH, and WITHOUT are similarly assigned * the same precedence as IDENT. This allows resolving conflicts in the * json_predicate_type_constraint and json_key_uniqueness_constraint_opt * productions (see comments there). * * Like the UNBOUNDED PRECEDING/FOLLOWING case, NESTED is assigned a lower * precedence than PATH to fix ambiguity in the json_table production. */ %nonassoc UNBOUNDED NESTED /* ideally would have same precedence as IDENT */ %nonassoc IDENT PARTITION RANGE ROWS GROUPS PRECEDING FOLLOWING CUBE ROLLUP SET KEYS OBJECT_P SCALAR VALUE_P WITH WITHOUT PATH %left Op OPERATOR /* multi-character ops and user-defined operators */ %left '+' '-' %left '*' '/' '%' %left '^' /* Unary Operators */ %left AT /* sets precedence for AT TIME ZONE, AT LOCAL */ %left COLLATE %right UMINUS %left '[' ']' %left '(' ')' %left TYPECAST %left '.' /* * These might seem to be low-precedence, but actually they are not part * of the arithmetic hierarchy at all in their use as JOIN operators. * We make them high-precedence to support their use as function names. * They wouldn't be given a precedence at all, were it not that we need * left-associativity among the JOIN rules themselves. */ %left JOIN CROSS LEFT FULL RIGHT INNER_P NATURAL %% /* * The target production for the whole parse. * * Ordinarily we parse a list of statements, but if we see one of the * special MODE_XXX symbols as first token, we parse something else. * The options here correspond to enum RawParseMode, which see for details. */ parse_toplevel: stmtmulti { pg_yyget_extra(yyscanner)->parsetree = $1; (void) yynerrs; /* suppress compiler warning */ } | MODE_TYPE_NAME Typename { pg_yyget_extra(yyscanner)->parsetree = list_make1($2); } | MODE_PLPGSQL_EXPR PLpgSQL_Expr { pg_yyget_extra(yyscanner)->parsetree = list_make1(makeRawStmt($2, 0)); } | MODE_PLPGSQL_ASSIGN1 PLAssignStmt { PLAssignStmt *n = (PLAssignStmt *) $2; n->nnames = 1; pg_yyget_extra(yyscanner)->parsetree = list_make1(makeRawStmt((Node *) n, 0)); } | MODE_PLPGSQL_ASSIGN2 PLAssignStmt { PLAssignStmt *n = (PLAssignStmt *) $2; n->nnames = 2; pg_yyget_extra(yyscanner)->parsetree = list_make1(makeRawStmt((Node *) n, 0)); } | MODE_PLPGSQL_ASSIGN3 PLAssignStmt { PLAssignStmt *n = (PLAssignStmt *) $2; n->nnames = 3; pg_yyget_extra(yyscanner)->parsetree = list_make1(makeRawStmt((Node *) n, 0)); } ; /* * At top level, we wrap each stmt with a RawStmt node carrying start location * and length of the stmt's text.
