Native build ------------ 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, a file `config.cache' that saves the results of its tests to speed up reconfiguring, and a file `config.log' containing compiler output (useful mainly for debugging `configure'). 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.md' so they can be considered for the next release. If at some point `config.cache' contains results you don't want to keep, you may remove or edit it. The file `configure.in' is used to create `configure' by a program called `autoconf'. You only need `configure.in' 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. If you're using `csh' on an old version of System V, you might need to type `sh ./configure' instead to prevent `csh' from trying to execute `configure' itself. Running `configure' takes awhile. While running, it prints some messages telling which features it is checking for. 2. Type `make' to compile the package. (Add e.g. `-j8` to run up to 8 simultanerous compiler processes to speed this up.) 3. Optionally, type `make check' to run any self-tests that come with the package. 4. Type `make install' to install the programs and any data files and documentation. 5. 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. CMake build ----------- With CMake you can generate a build setup in your choice of build system. The one I'm most familiar with is `make`. Like the native build, the CMake build needs the libpq library and headers installed. But in addition, it also needs the `pg_type.h` header installed. On some systems this will be in one of the `postgresql-server-dev-*` packages. That extra header is just to allow CMake to detect that you have a PostgreSQL development setup installed. The build shouldn't actually need the file otherwise, so if you can't find the file, it may be enough to create an empty file in the right place. The CMake build works like: 1. Go into the directory where you would like to build the library and its intermediate files. This may be the source directory. 2. Enter `cmake `, where `` is the location of the libpqxx source code. This generates the build configuration. 3. Type `make' to compile the package. (Add e.g. `-j8` to run up to 8 simultanerous compiler processes to speed this up.) Compilers and Options ===================== Some systems require unusual options for compilation or linking that the `configure' script does not know about. You can give `configure' initial values for variables by setting them in the environment, or by adding them to the `configure` command line: ./configure CXX='clang++' CXXFLAGS=-O3 LIBS=-lposix 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 must use a version of `make' that supports the `VPATH' variable, such as 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 `..'. If you have to use a `make' that does not supports the `VPATH' variable, you have 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. Installation Names ================== By default, `make install' will install the package's files in `/usr/local/bin', `/usr/local/man', etc. You can specify an installation prefix other than `/usr/local' by giving `configure' the option `--prefix=PATH'. You can specify separate installation prefixes for architecture-specific files and architecture-independent files. If you give `configure' the option `--exec-prefix=PATH', the package will use PATH as the prefix for installing programs and libraries. Documentation and other data files will still use the regular prefix. In addition, if you use an unusual directory layout you can give options like `--bindir=PATH' 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. 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'. Optional Features ================= 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.md' 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. Specifying the System Type ========================== There may be some features `configure' can not figure out automatically, but needs to determine by the type of host the package will run on. Usually `configure' can figure that out, but if it prints a message saying it can not guess the host type, give it the `--host=TYPE' option. TYPE can either be a short name for the system type, such as `sun4', or a canonical name with three fields: CPU-COMPANY-SYSTEM 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 host type. If you are building compiler tools for cross-compiling, you can also use the `--target=TYPE' option to select the type of system they will produce code for and the `--build=TYPE' option to select the type of system on which you are compiling the package. 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. Operation Controls ================== `configure' recognizes the following options to control how it operates. `--cache-file=FILE' Use and save the results of the tests in FILE instead of `./config.cache'. Set FILE to `/dev/null' to disable caching, for debugging `configure'. `--help' Print a summary of the options to `configure', and exit. `--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. `--version' Print the version of Autoconf used to generate the `configure' script, and exit. `configure' also accepts some other, not widely useful, options. libpqxx-6.4.5/Makefile.am000066400000000000000000000011471350065432700152610ustar00rootroot00000000000000SUBDIRS = include src test tools win32 config doc EXTRA_DIST = autogen.sh configitems README.md README-UPGRADE VERSION MAINTAINERCLEANFILES = \ Makefile.in aclocal.m4 config.h.in config.log configure stamp-h.in pkgconfigdir = $(libdir)/pkgconfig pkgconfig_DATA = libpqxx.pc TESTS = tools/lint # Generate ChangeLog from git history.

Thanks Ivan Poiakov. - Fix string conversion to bool for "1". Thanks Amaracs. - Fix in escaping of strings in arrays. Thanks smirql. - Faster copying of results of large queries. Thanks Vsevolod Strukchinsky. - Starting to handle encodings properly! Thanks to Joseph Durel. - No longer using std::iterator (deprecated in C++17). 6.2.5 - Removed deprecated pqxx-config. - Build fix on Visual C++ when not defining NOMINMAX. - Reduce setup code for string conversions, hopefully improving speed. - Allow nul bytes in tablereader. - Support defining string conversions for enum types. - Fixed const/pure attributes warning in gcc 8. - Updated build documentation to mention CMake option. - Fixed a floating-point string conversion failure with Visual Studio 2017. 6.2.4 - Fix builds in paths containing non-ASCII characters. - New macro: PQXX_HIDE_EXP_OPTIONAL (to work around a client build error). 6.2.3 - Build fixes. 6.2.2 - Variable number of arguments to prepared or parameterised statement (#75). - Windows build fix (#76). 6.2.1 - Compile fixes. 6.2.0 - At last! A check against version mismatch between library and headers. - Small compile fixes. 6.1.1 - Small compile fixes. - A particular error string would always come out empty. 6.1.0 - Dependencies among headers have changed. You may need extra includes. - Library headers now include "*.hxx" directly, not the user-level headers. - Supports parsing of SQL arrays, when using "ASCII-like" encodings. 6.0.0 - C++11 is now required. Your compiler must have shared_ptr, noexcept, etc. - Removed configure.ac.in; we now use configure.ac directly. - Removed pqxx::items. Use the new C++11 initialiser syntax. - Removed maketemporary. We weren't using it. - Can now be built outside the source tree. - New, simpler, lambda-friendly transactor framework. - New, simpler, prepared statements and parameterised statements. - Result rows can be passed around independently. - New exec0(): perform query, expect zero rows of data. - New exec1(): perform query, expect (and return) a single row of data. - New exec_n(): perform query, expect exactly n rows of data. - No longer defines Visual Studio's NOMINMAX in headers. - Much faster configure script. - Most configuration items are gone. - Retired all existing capability flags. - Uses WSAPoll() on Windows. - Documentation on readthedocs.org, thanks Tim Sheerman-Chase. 5.1.0 - Releases after this will require C++11! - Internal simplification to pqxx::result. - A row object now keeps its result object alive. - New exec() variants: "expect & return 1 row," "expect no rows," "expect n." - ChangeLog is gone. It was a drag on maintenance. 5.0.1 - Exposed sqlstate in sql_error exception class. 5.0 - The PGSTD namespace alias is gone. Use the std namespace directly. - pqxx::tuple is now pqxx::row, to avoid clashes with std::tuple. - Deprecated escape_binary functions dropped. - Deprecated notify_listener class dropped. - Support for many old compilers dropped. - Support for "long long" and "long double" types is always enabled. - No longer uses obsolete std::tr1 namespace; use plain std instead. - Now requires libpq 9.1 or better. - Requires server version 9.1 or better. - Support for REPEATABLE READ isolation level added. - Makefile fixes for Visual Studio 2013. - Supports C++11 and C++14. - No longer has obsolete debian & RPM packaging built in. - Fixed failure to abort uncommitted subtransactions on destruction. - Fixed failure to detect some integer overflows during conversion. - Build tooling uses /usr/bin/env python instead of /usr/bin/python. - New configure options: --with-postgres-include and --with-postgres-lib. - In g++ or compatible compilers, non-exported items are no longer accessible. - Many build fixes for various platforms and compilers. 4.0 - API change: noticers are gone!

Make sure that your libpqxx is built against the same version of the C++ standard as your own application, or there may be build problems. It may be possible to paper over some mismatches. If your application build fails with errors about `std::experimental::optional`, try defining a macro `PQXX_HIDE_EXP_OPTIONAL` in your application's build. This will suppress support for `std::experimental::optional` even if libpqxx was built to assume that the feature is present. libpqxx-6.4.5/README.md000066400000000000000000000453521350065432700145120ustar00rootroot00000000000000libpqxx ======= Welcome to libpqxx, the C++ API to the PostgreSQL database management system. Compiling this package requires PostgreSQL to be installed -- including the C headers for client development. The library builds on top of PostgreSQL's standard C API, libpq, though this fact is almost completely hidden from programmes which use libpqxx. As of release 6.0, C++11 is the minimum supported C++ version. Make sure your compiler supports this, and if necessary, that you have support for C++11 configured. **Version 7.0 will require C++17.** However, it's probably not a problem if your compiler does not implement C++17 fully. Initially the 7.x series will only require some basic C++17 features such as `std::string_view`. More advanced use may follow later. Also, **7.0 will make some breaking changes in rarely used APIs:** * All `connection` classes will be folded into a single class. * Custom `connection` classes will no longer be supported. * Connection reactivation will be explicit: _you_ call `activate()` if needed. * "String traits" (for string conversions) will have a slightly different API. Find libpqxx on Github: https://github.com/jtv/libpqxx Building libpqxx ---------------- There are three very different ways of building libpqxx: 1. Using CMake, on any system which supports it. 2. On Unix-like systems, using a `configure` script. 3. With Visual Studio on Windows, using supplied project files and headers. The CMake build should work on any system where CMake is supported. This is a recently contributed alternative build, so if you run into problems, your help could be crucial in fixing them. The "Unix-like" section applies to systems that look like Unix: GNU/Linux, Apple OSX and the BSD family, AIX, HP-UX, Irix, Solaris, etc. Microsoft Windows with a Unix-like environment such as Cygwin or MinGW installed should also work in the same way. There is a separate section below for a Visual C++ build on Windows. It takes a bit of work, and if the CMake build works well, we may drop support for the Windows/Visual C++ build later. ### Using CMake On CMake the standard way of working is to have the source tree in one directory, and build in another. (The `configure` script supports this as well, but that build is enough work that I didn't bother documenting it.) Let's say you have the libpqxx source tree in a location `$SOURCE`, and are building in a different location `$BUILD`. CMake also lets you choose whether to run the ultimate build through `make`, or some other tool. The default on Unix-like systems is `make`, but you may have to look in the CMake documentation what works well on your system. For a default build, using those two directories, go into `$BUILD` and run: ```shell cmake $SOURCE ``` This sets up the build, in your current directory. Stay in the `$SOURCE` directory, and run: ```shell make ``` If you have multiple cores that you want to put to good use, use the `-j` option to make it run multiple jobs in parallel. For instance, if you have 8 CPU cores, you'll probably want to be compiling about 8 files simultaneously: ```shell make -j8 ``` ### On Unix-like systems For the Unix-like systems the procedure is the standard "configure, make, make install" sequence. In order to run the test suite, you'll also need to set up a database for the tests to play with. Run the "configure" script with the `--help` option to see build and installation options. You need to get these right before you compile. Then: ```shell ./configure # (plus any options you find appropriate) make ``` This will compile the library. You'll also want to run the test suite to make sure that everything works. To prepare for that, you need to set up a disposable test database that the test suite to play with. You'll want password-less authentication so that you won't need to log in for every test. In this example, the test database is called pqxx-test and runs on a server at IP address 192.168.1.99. Before running the test, make sure you can log into your test database with psql, the command-line SQL shell that comes with PostgreSQL: ```shell PGHOST=192.168.1.99 PGDATฺABASE=pqxx-test psql ``` Once you have that working, use the same login parameters to run the libpqxx test suite: ```shell make PGHOST=192.168.1.99 PGDATABASE=pqxx-test check ``` Assuming that the test suite runs successfully, you are now ready to install. You'll typically need superuser privileges to run this command: ```shell make install ``` Now you should be able to link your own programs with libpqxx. If something went wrong along the way, or what you have isn't quite what you wanted, it's time to move on to that fineprint that we hinted at earlier. #### 1. Configure A word on the configure script. It needs to find the C header and the binary for libpq, the C-level client library, so that the libpqxx build procedure can make use of them. The configure script finds these files by running a script called pg\_config that comes with PostgresQL. If you have postgres installed, pg\_config should be somewhere on your system. It will "know" where the relevant files are. The configure script just needs to run it. Make sure that the folder containing pg\_config is in your executable path before you run the configure script, or it will fail with a message like: ``` configure: error: PostgreSQL configuration script pg_config was not found. ``` If you don't want to have pg\_config in your path for whatever reason, or you have multiple PostgreSQL installations on your system (each with their own copy of pg\_config) and wish to override the default version, add an option like this to your "configure" command line: ```shell PG_CONFIG=/home/me/postgres/bin/pg_config ``` Here, "/home/me/postgres/bin/pg\_config" is just an example of where your preferred copy of pg\_config might be. This would tell the configure script that you wish to build a libpqxx based on the postgres version found in /home/me/postgres. About installing: if you wish to install libpqxx in a custom location, such as your home directory /home/me, you can specify this to the configure script before you build libpqxx. You select the installation location using the configure script's --prefix option, e.g.: ```shell ./configure --prefix=/home/me ``` A custom location can be useful to keep locally-build software separate from packaged software. Conventional installation locations for custom software on Unix-like systems are /usr/local and /opt. Custom installation locations can also be handy if you don't have administrator rights on the machine you're working on! The configure scripts supports many other options to tweak how and where libpqxx is to be built and installed; try the --help option to get an overview if you're interested. If configuration just plain won't work for whatever reason: take a look in the config/sample-headers/ directory. Here you will find configuration headers for various compilers and libpq versions. Pick the config-internal-\*.h and config-public-\*.h headers for the compiler and libpq version most closely matching your own, and see if they work for you. You may also want to tweak them manually. #### 2. Make One problem some people have run into at this stage is that the header files for PostgreSQL need the OpenSSL header files to be installed. If this happens to you, make sure openssl is installed and its headers are in your compiler's include path. #### 3. Make Check "Make check" is where you compile and run the test suite that verifies the library's functionality. The "make check" procedure needs a database to play with. It will create and drop various tables in that database. Use a throwaway database for this or risk losing data! (Actually the test only manipulates tables whose names start with "pqxx" so in practice the risk will be small. But better safe than sorry: use a disposable test database separate from your own data.) To direct the test suite to the right database, set some or all of the following environment variables as needed for "make check": ``` PGDATABASE (name of database; defaults to your user name) PGHOST (database server; defaults to local machine) PGPORT (TCP port to connect to; default is 5432) PGUSER (your PostgreSQL user ID; defaults to your login name) PGPASSWORD (your PostgreSQL password, if needed) ``` Further environment variables that may be of use to you are documented in the libpq documentation and in the manpage for Postgres' command-line client, psql. Setting environment variables works differently depending on your shell, but try one of these: ```shell VARIABLE=value export VARIABLE ``` or ```shell set VARIABLE=value ``` Try printing the variable afterwards to make sure. The command is normally ```shell echo $VARIABLE ``` If you set the variable successfully, it should print the value you assigned. It will print nothing if you failed to set the variable. On Unix-like systems, postgres may be listening on a Unix domain socket instead of a TCP port. The socket will appear as a file somewhere in the filesystem with a name like .s.PGSQL.5432. To connect to this type of socket, set PGHOST to the directory where you find this file, as an absolute path. For example, it may be "/tmp" or "/var/run" or "/var/run/postgresql". The leading slash tells libpq that this is not a network address but a local Unix socket. #### 4. Make Install This is where you install the libpqxx library and header files to your system. Assuming this succeeds, you should now be able to build your own programs by adding the location of the header files (e.g. /usr/local/pqxx/include) to your compiler's include path when compiling your application. Similarly, add the location of the library binary (e.g. /usr/local/pqxx/lib) to your library search path when linking your application. See the documentation and the test programs for more information on using libpqxx. If you link with the dynamic version of the library, you may find that your program fails to run because the run-time loader cannot find the library. There are several ways around that. Pick the first option that works for you: 1. by linking to the static version of the library, or 2. adding a link to the dynamic libpqxx library somewhere in your system's standard library locations, or 3. adding libpqxx's lib/ directory to your loader's search path before running your program. On Unix-like systems including GNU/Linux, the loader's search path can be extended by setting the LD\_LIBRARY\_PATH variable. Enjoy! ### On Microsoft Windows Project files for Visual C++ are provided in the win32 directory, along with some other Windows-specific material. These are very old, so if you run into problems, please let us know what we can do to fix them. One known problem is that _folder names with spaces in them_ cause trouble. If you run into trouble, try using the alternative build using CMake! As yet another alternative, if you are running a Unix-like environment such as Cygwin, you may want to try if the Unix build procedure works for you. In theory it should be possible to run the configure script and build with Visual C++ or any other compiler, so long as you have a reasonably Unix-like shell environment. If you do proceed with the Visual C++ files, you'll need to copy the most appropriate compile-time configuration files from various subdirectories in config/example-headers/ to include/pqxx. You'll want to tweak them manually to define the exact features your system, compiler, and PostgreSQL versions support. On a Unix-like system the configure script would do this for you. Before trying to compile with Visual C++, you'll at least need to copy the file win32/common-sample to win32/common, and edit the latter to reflect the proper paths to your PostgreSQL headers and the libpq library. See the win32 subdirectory for more documentation. #### Manual Configuration: config-\*-\*.h Normally, on any vaguely Unix-like system, the configuration headers (called config-internal-\*.h for the library's internal use, config-public-\*.h for both the library and client programs) are generated from config.h.in. All these files, once generated, are situated in the include/pqxx/ directory. The configitems file lists all configuration items and where they go; but see win32/INSTALL.txt for a detailed description of how these files work. Getting the compiler-related configuration right can take several stages of trying to build, looking at error messages, looking for configuration items that may be related, changing them, and building again. If nothing seems to help, register an issue on Github. Be sure to read the FAQ though, because there are some known problems. #### Windows-Specific Build Problems One problem specific to Windows is that apparently it doesn't let you free memory in a DLL that was allocated in the main program or in another DLL, or vice versa. This can cause trouble when setting your own notice handlers to process error or warning output. Recommended practice is to build libpqxx as a static library, not a DLL. Documentation ------------- The doc/ directory contains API reference documentation and a tutorial, both in HTML format. These are also available online. For more detailed information, look at the header files themselves. These are in the include/pqxx/ directory. The reference documentation is extracted from the headers using a program called Doxygen. When learning about programming with libpqxx, you'll want to start off by reading about the `connection_base` class and its children, as well as the `transaction_base` class. For programming examples, take a look at the test programs in the test/ directory. If you don't know how a certain function or class is used, try searching the test programs for that name. Programming with libpqxx ------------------------ Your first program will involve the libpqxx classes "connection" (see headers `pqxx/connection_base.hxx` and `pqxx/connection.hxx`), and `work` (a convenience alias for `transaction<>` which conforms to the interface defined in `pqxx/transaction_base.hxx`). These `*.hxx` headers are not the ones you include in your program. Instead, include the versions without filename suffix (e.g. `pqxx/connection_base`). Those will include the actual .hxx files for you. This was done so that includes are in standard C++ style (as in `` etc.), but an editor will still recognize them as files containing C++ code. Continuing the list of classes, you will most likely also need the result class (`pqxx/result.hxx`). In a nutshell, you create a `connection` based on a Postgres connection string (see below), create a `work` in the context of that connection, and run one or more queries on the work which return `result` objects. The results are containers of rows of data, each of which you can treat as an array of strings: one for each field in the row. It's that simple. Here is a simple example program to get you going, with full error handling: ```c++ #include #include int main() { try { pqxx::connection C; std::cout << "Connected to " << C.dbname() << std::endl; pqxx::work W(C); pqxx::result R = W.exec("SELECT name FROM employee"); std::cout << "Found " << R.size() << "employees:" << std::endl; for (auto row: R) std::cout << row[0].c_str() << std::endl; std::cout << "Doubling all employees' salaries..." << std::endl; W.exec("UPDATE employee SET salary = salary*2"); std::cout << "Making changes definite: "; W.commit(); std::cout << "OK." << std::endl; } catch (const std::exception &e) { std::cerr << e.what() << std::endl; return 1; } return 0; } ``` Connection strings ------------------ Postgres connection strings state which database server you wish to connect to, under which username, using which password, and so on. Their format is defined in the documentation for libpq, the C client interface for PostgreSQL. Alternatively, these values may be defined by setting certain environment variables as documented in e.g. the manual for psql, the command line interface to PostgreSQL. Again the definitions are the same for libpqxx-based programs. The connection strings and variables are not fully and definitively documented here; this document will tell you just enough to get going. Check the PostgreSQL documentation for authoritative information. The connection string consists of attribute=value pairs separated by spaces, e.g. "user=john password=1x2y3z4". The valid attributes include: - `host` Name of server to connect to, or the full file path (beginning with a slash) to a Unix-domain socket on the local machine. Defaults to "/tmp". Equivalent to (but overrides) environment variable PGHOST. - `hostaddr` IP address of a server to connect to; mutually exclusive with "host". - `port` Port number at the server host to connect to, or socket file name extension for Unix-domain connections. Equivalent to (but overrides) environment variable PGPORT. - `dbname` Name of the database to connect to. A single server may host multiple databases. Defaults to the same name as the current user's name. Equivalent to (but overrides) environment variable PGDATABASE. - `user` User name to connect under. This defaults to the name of the current user, although PostgreSQL users are not necessarily the same thing as system users. - `requiressl` If set to 1, demands an encrypted SSL connection (and fails if no SSL connection can be created). Settings in the connection strings override the environment variables, which in turn override the default, on a variable-by-variable basis. You only need to define those variables that require non-default values. Linking with libpqxx -------------------- To link your final program, make sure you link to both the C-level libpq library and the actual C++ library, libpqxx. With most Unix-style compilers, you'd do this using the options ``` -lpqxx -lpq ``` while linking. Both libraries must be in your link path, so the linker knows where to find them. Any dynamic libraries you use must also be in a place where the loader can find them when loading your program at runtime. Some users have reported problems using the above syntax, however, particularly when multiple versions of libpqxx are partially or incorrectly installed on the system. If you get massive link errors, try removing the "-lpqxx" argument from the command line and replacing it with the name of the libpqxx library binary instead. That's typically libpqxx.a, but you'll have to add the path to its location as well, e.g. /usr/local/pqxx/lib/libpqxx.a. This will ensure that the linker will use that exact version of the library rather than one found elsewhere on the system, and eliminate worries about the exact right version of the library being installed with your program.. libpqxx-6.4.5/VERSION000066400000000000000000000000061350065432700142660ustar00rootroot000000000000006.4.5 libpqxx-6.4.5/aclocal.m4000066400000000000000000002243401350065432700150670ustar00rootroot00000000000000# generated automatically by aclocal 1.15.1 -*- Autoconf -*- # Copyright (C) 1996-2017 Free Software Foundation, Inc. # This file is free software; the Free Software Foundation # gives unlimited permission to copy and/or distribute it, # with or without modifications, as long as this notice is preserved. # This program is distributed in the hope that it will be useful, # but WITHOUT ANY WARRANTY, to the extent permitted by law; without # even the implied warranty of MERCHANTABILITY or FITNESS FOR A # PARTICULAR PURPOSE. m4_ifndef([AC_CONFIG_MACRO_DIRS], [m4_defun([_AM_CONFIG_MACRO_DIRS], [])m4_defun([AC_CONFIG_MACRO_DIRS], [_AM_CONFIG_MACRO_DIRS($@)])]) m4_ifndef([AC_AUTOCONF_VERSION], [m4_copy([m4_PACKAGE_VERSION], [AC_AUTOCONF_VERSION])])dnl m4_if(m4_defn([AC_AUTOCONF_VERSION]), [2.69],, [m4_warning([this file was generated for autoconf 2.69.

Vermeulen 2002—2017 Jeroen T. Vermeulen About libpqxx libpqxx is a C++ API for PostgreSQL. Since libpqxx builds on top of the C frontend libpq, you will need a working libpq library on your system prior to getting started with libpqxx. This is similar to the situation with the older libpq++ interface. See the Github page for more information. Class overview To work with libpqxx, you need to be aware of at least the following classes. These are all introduced in a dedicated namespace, pqxx: connection represents a connection from your program to a PostgreSQL back-end server. Naturally your program may open multiple connections, simultaneous or not, to any number of databases. work, actually an alias for the transaction class template, represents a transaction being executed in the context of a connection. This is a unit of work that must be completed as a whole by the database backend. If execution fails, everything done within that transaction is undone by the backend as if it had never happened. Actually libpqxx provides three classes doing this at various levels of reliability, called nontransaction, transaction, and robusttransaction for no, standard, and best reliability respectively. You probably shouldn't mess with robusttransaction though, because it comes with complications. You may execute any number of transactions on a single connection, but only one at a time. I recommend that you do not set up your own transactions, but have them managed for you by a transactor instead (see below). A result is a container holding the resulting data coming out of a query or command executed in a transaction. It behaves just like a standard C++ container as found in the STL, although its contents can't be modified in any way. (You can assign or copy it cheaply though; it's basically a smart pointer). The rows held in the result in turn behave much like non-modifiable containers themselves. I would also like to use this opportunity to plug the esc function, which you should use whenever you want to include a variable as a string in your SQL (eg. insert it into a text field in a table). See below. There are other classes that may be of interest to you, but which you don't necessarily need to be aware of for writing programs. You will probably want to look them up at some point when it becomes necessary to figure out complex compiler warnings. Some of the classes you may become interested in fairly quickly are: broken_connection is an exception class that is thrown if libpqxx loses its connection to the back-end. It is derived from the standard C++ exception std::runtime_error, and can generally be treated as such. sql_error is an exception class that is thrown if a query to the back-end fails. Like broken_connection it is derived from std::runtime_error, but it also carries information about the failed query. This may be useful for debugging. icursorstream is a way of iterating over a query result using an SQL cursor. This can be useful for selectively retrieving parts of a query, or for retrieving and processing results in chunks so your program can do useful work on one chunk while the next is still coming in over a network connection. Or you may want to use this to give progress reports to the user between chunk transfers. in_doubt_error is an exception class to indicate a rare and difficult error condition. Explaining this is a bit painful, since it invalidates some of what was said above (and is commonly said in the database world). In theory, a "transaction" is an integral, atomic unit of work that either fails or succeeds. This is a beautiful idea, but in practice there is nothing that cannot be broken. There is a tiny risk that, like Schroedinger's Cat, the transaction can end up in an indeterminate state. This happens when the connection to the backend is lost just when you were waiting for confirmation after completing your transaction. Your transaction may have succeeded (in fact it probably has), but if the connection is lost during just this small time window, there is no way to confirm this to your application. When this happens, libpqxx throws an in_doubt_error on the client side, which you may want to catch as a special case. If you do, make sure all alarm bells go off! See also the description for robusttransaction, which sacrifices some performance to minimize this risk. nontransaction is just like a regular transaction as far your code is concerned (except that it's not a template). The big difference is that where the latter opens a back-end transaction to keep your view and modifications of the database atomic, the former does nothing to maintain integrity. It just passes your queries directly to the database, with no enclosing transaction. This difference is expressed by the fact that the other transaction classes are derived from dbtransaction, an abstract class that expresses the presence of a real backend transaction, whereas nontransaction is not. This may give you better performance if your transaction does not modify the database, but if it does, may have unforeseen implications if you expect certain levels of consistency in the database--especially if other processes or threads may be modifying the database at the same time. You'll probably only want to use this in the following cases: If you only want to read from the database, not modify it, and you know that the data is not going to be updated while your program is running. If you are interested in always getting the very latest information out of your database, even if that means that you may not get a temporally consistent view of the database. When making changes to the database schema; some operations may not be supported by the backend inside backend transactions. robusttransaction (a template just like transaction) is essentially the same as a transaction, ie. an atomic unit of work, except that it works harder to prevent in_doubt_errors from happening. This comes at the cost of some performance, which is one reason why this behaviour isn't the default. It also creates some extra tables in your database to keep track of what's happening. Use this class instead of plain old transaction if you get in_doubt_errors in your application--but only after thoroughly inspecting your code for bugs that might be causing the problem, or you'll only be hiding glitches that should be fixed instead. transaction_base defines the common public interface for the transaction-like classes: nontransaction, robusttransaction, and transaction itself. To look up methods available in these classes, see the definition (or documentation) for transaction_base instead. You'll usually want to refer to the default transaction type as work, an alias that means "transaction with default (read-committed) isolation level." transactor<> provides a framework that makes it easier for you to write correct, robust transaction code to be executed in a transaction. You should generally try to write your code as a class derived from transactor<>, but this is not required. A transactor-derived class may select its own "quality of service" in transactional integrity by choosing a transaction type as its template argument, e.g. transactor<robusttransaction<> >. The default transactor<> is equivalent to transactor<work>. Within your class you can refer to the transaction type used as argument_type. notification_receiver is an instance of the Observer design pattern. Any code connected to a backend may flag an event using the PostgreSQL NOTIFY command. Frontends connected to that same backend database may be listening for an event of that name to occur. A frontend using libpqxx does this by registering an observer object derived from notification_receiver, which will be invoked by libpqxx to handle the event when it occurs. Something every programmer using notification receivers in PostgreSQL should know, by the way, is that notifications are not delivered to your program while it is inside a back-end transaction. Nor are they sent until the notifying process has committed any transaction it may be in. This makes sense from a correctness point of view (otherwise your processing of the event might get rolled back just because the transaction you're in happens to fail), but may be a little confusing to the unaware programmer. row refers to a row of data within a result object. field refers to one field within a row. A field contains one retrieved value such as a number or a string, and can be read into variables of various types such as ints or strings. result::const_iterator allows you to enumerate the rows in a result in a similar way to the iterators defined by any standard C++ container. result::row::const_iterator similarly iterates over the fields in a row. Finally, there are also some functions that you may want to know about, that live alone in the pqxx namespace without being part of any class: esc, found in the transaction classes, is the canonical way to use strings in your SQL. This function escapes any quotes, backslashes, and other characters in your input string that would otherwise cause syntax errors (or worse, security holes) in your queries when included directly. Use these functions whenever you want to have a variable string in your SQL queries. If you don't, you'll be left with annoying bugs or possibly even security holes in your program. Use this function, use this function, use this function. Please. Make me proud. to_string knows how to render many types of values as strings. This is used internally by libpqxx to convert values coming out of or going into the backend, and doesn't respect locale settings. from_string is the inverse of to_string. It is used by eg. field::to() to convert the incoming field data (which is in text format) to the desired C++ type. Tutorial
Before we begin programming
This document This frontend library is built on top of the libpq frontend library, which defines PostgreSQL's C API. Therefore this manual will sometimes refer to the libpq documentation rather than repeat what is said there. This was not done to annoy you, but to ensure that the libpqxx documentation remains up-to-date with any changes in the C frontend. Please bear with us. Furthermore, if you're ever in doubt about how to use the basic features of libpqxx, take a look at the example programs provided; they're called test000, test001 etc. Those should help give you an idea of how simple the library can be in practice. Don't let that keep you from submitting a request for improved documentation though; your questions define what this tutorial needs to say!
C++ conventions All definitions made by libpqxx reside in a namespace pqxx. If you're not familiar with C++ namespaces, you have two options: Always import the whole of the pqxx namespace in your programs. This tells the compiler to always look in the pqxx namespace when trying to resolve a name that doesn't occur in the global (ie. the "default") namespace). To do this, include the directive using namespace pqxx; near the top of each source file that uses libpqxx. This is typically best for your source files (you're probably doing it already for the std namespace), though it is not considered good practice in header files. Explicitly qualify each libpqxx name with the pqxx namespace. This will tell the compiler exactly which names are supposed to be in the pqxx namespace, avoiding any confusion over multiple classes or functions used in your program possibly having the same name. As long as they're in different namespaces, the compiler will be able to tell them apart without trouble. To do this, write pqxx::connection instead of connection, pqxx::result::const_iterator instead of result::const_iterator, and so on. This is the mode of address you will typically want to use in header files, to avoid polluting the namespaces of the actual source files with the definitions of the extra namespace.
Setting up a connection The very first thing to do before we can begin working with a database, is actually connect to one. We do this by creating a connection object that will serve as our "handle" on the connection: connection Conn("dbname=test"); This gives us a connection object called Conn. The connection constructor here takes one argument, the "connect string." This string may be used to specify which host on the network runs the database backend we wish to connect to, which database we're interested in, which user name we'll be using to log in, etc. Refer to the libpq connect call for a complete definition of what may go into the connect string. In this case we're connecting to a database test residing on the local machine. By default the client will try to connect to a server running on the local machine. If no connection could be established, the connection constructor may throw an exception immediately; or it may decide to retry the connection later in case the problem is only temporary. In the latter case, an exception may occur at some later point if the problem turns out not to be so temporary after all. The connection can now act as a "service counter" for our database; your client will use it to perform one or more transactions related to the database. Connections cannot be copied or assigned. Any attempt to do so will be met with a compiler error. As a matter of design, libpqxx will not allow you to perform queries on the connection directly. You will need to open a transaction instead. See the section on transactions below.
Performing a transaction
What's a Transaction? A transaction demarcates a "unit of work" operating on the database, ie. a series of operations that must either complete successfully, or if it is aborted at any stage, must not affect the data in the database at all. Hence the process of completing a transaction is called the "commit" operation, and the process of aborting it and undoing any changes it may have made is called "rollback." All access to the database in libpqxx must go through a transaction object, so familiarity with this class family's interface is essential.
Creating a transaction object Creating a transaction object is not normally something you will have to do. The transactor class, discussed below, will take care of that and some other red tape besides. Still, there are cases where creating the object is unavoidable (when acting on multiple database connections simultaneously) or just plain easier to do. Please consider using a transactor whereever possible. When creating a transaction, pass it the connection object it is to act on, and optionally an identifying name for your transaction. The name, which need not be unique but should begin with a letter and may contain only letters, digits and underscores, can be used by libpqxx to make some error messages more specific. transaction<> Xaction(Conn, "DemoTransaction"); Or, alternatively (once you get fed up with typing transaction<>): work Xaction(Conn, "DemoTransaction"); The lifetime of the transaction object demarcates the unit of work. Its construction marks the beginning of the transaction, and its destruction means that the transaction is ended--whether through commit or rollback. The transaction class hierarchy is built on the principle of "explicit commit," ie. the commit operation must always be explicit in the code. If the transaction is destroyed before a commit was given, the transaction is implicitly aborted (rolled back). If your transaction makes no changes to the database, however, there is nothing to commit or roll back and the commit may safely be omitted. Destroying the connection object while the transaction still exists is an error that may result in a program crash, although the library will try to log an error message. Transactions cannot be copied, nor assigned, nor constructed without a connection (default-constructed); attempts to do any of these will result in compile errors.
Ending a transaction A transaction ends either successfully through an explicit commit command, or unsuccessfully in any of a number of ways. The following are the ways to end a transaction: The transaction may be committed through its commit member function: Xaction.commit(); The commit operation is sent to the backend at the point where the commit call occurs. Any exceptions generated by the database transaction will be thrown from here at the latest. The only exceptions that may be generated by Xaction beyond this point are related to incorrect handling of the transaction object, eg. if an attempt is made to abort Xaction after it has been committed, or runtime errors such as memory running out. As a consequence, any streams or cursors nested within the transaction (to be discussed later) must have been closed before the commit(). To do otherwise could possibly allow a transaction to be committed before all related actions had completed. The library will throw an exception if any streams are still open when the transaction is ended. A transaction is aborted if it is destroyed without having been explicitly committed: { work Xaction(Conn, "DemoTransaction"); // (Queries) } // Xaction destroyed here work *XactionP = new work(Conn, "DemoTransaction"); // (Queries) delete XactionP; // Xaction destroyed here try { work Xaction(Conn, "DemoTransaction"); // (Queries) Xaction.commit(); // If we get here, Xaction is committed } catch (...) { // If we get here, Xaction has been rolled back } No matter where exactly the decision to abort is made, the actual abort operation is sent to the backend when the transaction's destructor is called. If the abort fails, eg. because the network connection has been lost, no error is reported Throwing an exception from a destructor to report the error would have serious effects on program correctness. Never throw exceptions from a destructor. and the transaction will die of natural causes (either it has been closed by the backend already, or it soon will be if the connection is lost). If a database error occurs during the transaction, such as an SQL syntax error or lost connection to the backend, the transaction is aborted. work Xaction(Conn, "DemoTransaction"); try { // (Queries) Xaction.exec("SELECT !?^H^H^H^H"); // Fails: SQL syntax error } catch (...) { } Xaction.commit(); // ERROR: Xaction has already aborted! For this reason, it is recommended always to include the "commit" operation inside the try block (if any) surrounding the transaction code, not after the catch block. Think of it as a natural extension of structural programming: the transaction is "nested" within the connection, and the transaction code can be "nested" in a try/catch block. No more queries may be issued to the transaction regardless of how it ended; an exception will be thrown if the application attempts to continue the transaction after that time. Ending a transaction more than once is an error, except that aborting it multiple times is tolerated to facilitate error handling.
Executing queries So let's execute an actual query. There is no "query class" in libpqxx; we really do try to keep your life simple. A query is executed within a transaction by passing the query string to the transaction object's exec method. If the query fails to complete successfully, this method will throw the appropriate exception. The query itself is a standard C string in this case, ie. a const char * but you'll frequently want to use a C++ string to make it easy to include variables: void DeleteEntry(work &T, string Table, long ID) { T.exec("DELETE FROM " + Table + " WHERE ID=" + to_string(ID)); } In some places, even stringstreams will work, so you can use the full stream formatting capabilities, locales etc. in the standard C++ library to compose your SQL queries.
Getting query results Obviously not all queries are commands--the more common kind actually returns useful data. Result data in libpqxx are encapsulated in a result object, which acts as a container similar to the STL's vector template. result R = T.exec("SELECT firstname FROM employee WHERE lastname='Ng'"); This executes a query on the database, collects all matching data, and stores it in the form of a result. Two ways are provided to get at individual rows in a result: first, through indexing with the array index operator [] or the at member function, and second, through random-access iterators. Either will give you a row object that in turn can be addressed with the array index operator (or the at member function) or using iterators to get at its individual fields The difference between [] and at is that the latter is guaranteed to perform bounds-checking, throwing an exception if you pass it an illegal index value. With the array index operator you may get slightly better performance, but attempting to address a nonexistent row or field will result in undefined behaviour such as program crashes or inexplicably strange results. . Thus, R[0] will return the first ("zeroth") row in R. You won't normally want to bother with rows though; they don't contain the actual data, but rather serve as placeholders to later tell result which fields to fetch when field values from the row are requested. The class exists mostly for technical reasons related to the array index operators This is an instance of the Proxy implementation pattern, needed to allow a result to be indexed as if it were a two-dimensional array. C++'s array index operator doesn't allow this usage directly, but the operator can be applied to the result of a previous use of the same operator. The "result in the middle" needs to have a type of its own, though, and that's what row is for. . What you'll usually do is index the row directly to get at the field you want, e.g. R[0][0] to get the first field of the first row. Array indexing of rows also works with the fields' names instead of their numbers, eg.: // Process employees' names one by one. ProcessNames() doesn't know exactly // what columns are going to be in R, but there must be one called "lastname". void ProcessNames(result R) { for (result::size_type i = 0; i != R.size(); ++i) Process(R[i]["lastname"]); } As for the alternative, accessing the result rows through an iterator, only const iterators are provided so the contents of the result cannot be modified. Use these iterators as random-access iterators like with any STL-like container: for (result::const_iterator i = R.begin(); i != R.end(); ++i) Process(*i); Iterators may be incremented or decremented (whether pre- or post-), they may be added to or subtracted from to jump through the result rows; their positions may be compared (provided they point into the same result), and they may be dereferenced through the * or -> operators. Finally, the iterated rows' fields may be addressed using the array index operator on the iterator directly, eg. R.begin()[0] gets you the first field of R's first row, just like R[0][0] would Or (*R.begin())[0]. It may seem quirky to have R.begin() and *R.begin() mean the same thing, but it makes practical use of iterators a lot easier. In fact it matches how arrays and pointers work in C and C++. . Either way, once you've indexed the row you get a field--which is another placeholder, but this time encapsulates an actual field value in our query result. A field F also knows its column name, which can be obtained as F.Name(). Again, there is more than one way to read the field's value. Let's start out with the easy one, c_str, which reads the value as a C string: cout << "Name: " << F.c_str() << endl; This will return the empty string ("") if field F has the null value. Use is_null to see if this is the case: if (!F.is_null()) cout << "Name: " << F.c_str() << endl; In practice of course, not all data is going to consist of strings. Many fields will be integer values, or decimals, or Booleans. To convert the field's value to one of these, use its to method. This adapts itself to the type of variable you pass it, expecting the field value to be of an appropriate form for that type. For convenience, to returns false if the field had the null value, and true otherwise. In the former case, the variable will retain the value it had before the call. // Pay an employee his salary. Add bonus for managers. // The employee row must contain the fields void PaySalary(result::const_iterator empl) { long id; float salary; bool is_manager=false; // Get id. Must never be null. if (!empl[0].to(id)) throw runtime_error("No id!"); // Get salary. If this employee has no salary, skip payment. if (!empl[1].to(salary)) return; // Get manager status. If field is null, variable's original value (false) // will be preserved. empl[2].to(is_manager); if (is_manager) salary += Bonus; TransferMoney(id, salary); } If conversion fails, e.g. when trying to convert a floating-point value to an integer variable, to will throw a runtime_error reporting the problem in its what message.
Doing Transactions Right: Transactors Writing database code can be tricky. One of the most complicated areas is dealing with unexpected error conditions, such as losing one's connection to the database server. For long-running processes you'll frequently find yourself rewriting code for a simple transaction to make it: Attempt to perform the transaction. Check for "connection lost" errors. Attempt to restore the connection. Repeat until the transaction succeeds. This is bad for the heart, and clutters up your code besides. The transactor framework will take this work out of your hands if you let it.
Functors The mechanism is based on the concept of Functors, a powerful object-oriented design pattern that replaces the older practice of passing callback functions (or hooks, as they're sometimes called, or exits) to foreign code. Unlike classic callback functions, Functors provide an elegant way of maintaining custom state in your callback code, when the exact form or size of that state was not known in advance to the writer of the foreign code that will eventually invoke your callback. Functors in C++ are simple objects that can be invoked just like functions or function pointers can, by virtue of providing the function invocation operator, operator(). A simple functor could look like this: struct HelloFunctor { void operator()() { cout << "Hello World" << endl; } }; ...And once an object of this functor type has been created, it can be "invoked" just as if it were a function: HelloFunctor Hi; Hi(); But the invoking code may also be foreign code knowing nothing about the type of your functor. The foreign code is usually a template, so it automatically becomes "specialized" to your type of functor when the one meets the other: template<typename FUNCTOR> void DoFunctor(const FUNCTOR &Hi) { Hi(); } The great thing about functors is that they can carry state. This is most useful when you need to pass a functor object to foreign code like DoFunctor above, but you need certain extra parameters to be passed to your functor that the foreign code isn't going to pass. The classic C solution to this problem is to let you pass both a function pointer and a pointer-to-void as a method of letting you provide any type of data of your liking to it. This generally makes programs a little harder to read, and is not very safe or convenient. With functors, there is a better way to do the same thing. Let's say you want to adapt the HelloFunctor class to print its output to a different output stream. What you'd really like to do is add a parameter to your () operator to indicate which stream to print to: void operator()(ostream &Stream) { Stream << "Hello World" << endl; } Unfortunately, DoFunctor doesn't know about this new parameter, let alone what argument to pass! So instead, let's make this Stream a class member: struct HelloFunctor { ostream &Stream; // Set Stream when creating a HelloFunctor explicit HelloFunctor(ostream &S) : Stream(S) { } // Print to output stream selected at construction time void operator()() { Stream << "Hello World" << endl; } }; We can now provide the necessary information (ie., which stream to print to) to our HelloFunctor before we pass it to DoFunctor: HelloFunctor Hi1(cout), Hi2(cerr); DoFunctor(Hi1); // Print to cout DoFunctor(Hi2); // Print to cerr Naturally a functor's () operator may also return some other type than void, and it may take arguments just like any other function. This mechanism is used extensively by the STL to sort containers, to find items in sorted containers like set or map, and so on.
How Transactors Work A transactor is a functor derived from an instantiation of libpqxx's transactor class template. Instead of writing your database transaction inline with the rest of your code, you encapsulate it in your functor's () operator. When the time comes to execute your transaction, you create an object of your functor type and pass it to the perform method of your connection to the database. perform will make a copy of your transactor (which means it needs to be copy-constructible, by the way). It will also create a transaction object and invoke your transactor's () operator, passing the transaction object to it. All your transactor needs to do is perform its queries on this object and return, after which perform will commit the transaction. If your () operator throws an exception instead, perform will discard the copy of your original transactor, and try again with a new copy until it either succeeds or eventually gives up perform gives up if the transaction fails too many times in succession. The maximum number of attempts that are made can be passed to perform as an optional second argument. . If the connection is lost, the transaction will fail but perform will restore it transparently and simply try again. To make all this work, your transactor's () operator must make no changes to the rest of your program's state. Any intermediate results, data to be processed, and so on, must stay within your transactor, and be destroyed when the transactor is. That is the magic trick that allows perform to create copies of your transactor and use them to rerun the transaction as many times as needed, without your program noticing. So how does your transactor pass query results back to the outside world once it's done? For this purpose, you may redefine transactor's on_commit member function to pass any data back to the rest of your program. This member function will be called only if your transaction succeeded. (You may also wish to go the other route, storing data to variables outside the transactor right away, and override the on_abort and on_doubt functions to remove the data again if the transaction failed, but this is much more likely to cause subtle bugs.) Please refer to the reference manual, the source code, and the test programs that come with libpqxx to learn more about how transactors work.

In the context of that connection you can create * transactions, which in turn you can use to execute SQL. A connection can * have only one regular transaction open at a time, but you can break your work * down into any number of consecutive transactions and there is also some * support for transaction nesting (using the subtransaction class). * * Many things come together in the connection classes. Handling of error and * warning messages, for example, is defined by @e errorhandlers in the context * of a connection. Prepared statements are also defined here. * * @warning In libpqxx 7, all built-in connection types will be implemented * as a single class. You'll specify the connection policy as an optional * constructor argument. * * Several types of connections are available, including plain connection and * lazyconnection. These types are aliases combining a derivative of the * connection_base class (where essentially all connection-related functionality * is defined) with a policy class which governs how the connection is to be * established. You pass details such as the database you wish to connect to, * username and password, and so on as as PostgreSQL "connection string" and * certain environment variables that you can learn more about from the core * postgres documentation. * * See the connection_base documentation for a full list of features inherited * by all connection classes. Connections can be deactivated and reactivated if * needed (within reason, of course--you can't do this in the middle of a * transaction), and where possible, disabled or broken connections are * transparently re-enabled when you use them again.

They are documentation, not code. Keeping them in this form lets the documentation system process them in the same way as in-line documentation, supporting references back and forth between the two kinds. libpqxx-6.4.5/include/pqxx/doc/accessing-results.md000066400000000000000000000041401350065432700223710ustar00rootroot00000000000000Accessing results and result rows {#accessing-results} --------------------------------- Let's say you have a result object. For example, your program may have done: pqxx::result r = w.exec("SELECT * FROM mytable"); Now, how do you access the data inside `r`? Result sets act as standard C++ containers of rows. Rows act as standard C++ containers of fields. So the easiest way to go through them is: for (const auto &row: r) { for (const auto &field: row) std::cout << field.c_str() << '\t'; std::cout << std::endl; } But results and rows also support other kinds of access. Array-style indexing, for instance, such as `r[rownum]`: const int num_rows = r.size(); for (int rownum=0; rownum < num_rows; ++rownum) { const pqxx::row row = r[rownum]; const int num_cols = row.size(); for (int colnum=0; colnum < num_cols; ++colnum) { const pqxx::field field = row[colnum]; std::cout << field.c_str() << '\t'; } std::cout << std::endl; } And of course you can use classic "begin/end" loops: for (auto row = r.begin(); row != r.end(); row++) { for (auto field = row.begin(); field != row.end(); field++) std::cout << field->c_str() << '\t'; std::cout << std::endl; } Result sets are immutable, so all iterators on results and rows are actually `const_iterator`s. There are also `const_reverse_iterator` types, which iterate backwards from `rbegin()` to `rend()` exclusive. All these iterator types provide one extra bit of convenience that you won't normally find in C++ iterators: referential transparency. You don't need to dereference them to get to the row or field they refer to. That is, instead of `row->end()` you can also choose to say `row.end()`. Similarly, you may prefer `field.c_str()` over `field->c_str()`. This becomes really helpful with the array-indexing operator. With regular C++ iterators you would need ugly expressions like `(*row)[0]` or `row->operator[](0)`. With the iterator types defined by the result and row classes you can simply say `row[0]`. libpqxx-6.4.5/include/pqxx/doc/escaping.md000066400000000000000000000051171350065432700205310ustar00rootroot00000000000000String escaping {#escaping} =============== Writing queries as strings is easy. But sometimes you need a variable in there: `"SELECT id FROM user WHERE name = '" + name + "'"`. This is dangerous. See the bug? If `name` can contain quotes, you may have an SQL injection vulnerability there, where users can enter nasty stuff like "`.'; DROP TABLE user`". Or if you're lucky, it's just a nasty bug that you discover when `name` happens to be "d'Arcy". So, you'll need to _escape_ the `name` before you insert it. This is where quotes and other problematic characters are marked as "this is just a character in the string, not the end of the string." There are [several functions](@ref escaping-functions) in libpqxx to do this for you. SQL injection ------------- To understand what SQL injection vulnerabilities are and why they should be prevented, imagine you use the following SQL statement somewhere in your program: TX.exec( "SELECT number,amount " "FROM accounts " "WHERE allowed_to_see('" + userid + "','" + password + "')"); This shows a logged-in user important information on all accounts he is authorized to view. The userid and password strings are variables entered by the user himself. Now, if the user is actually an attacker who knows (or can guess) the general shape of this SQL statement, imagine he enters the following password: x') OR ('x' = 'x Does that make sense to you? Probably not. But if this is inserted into the SQL string by the C++ code above, the query becomes: SELECT number,amount FROM accounts WHERE allowed_to_see('user','x') OR ('x' = 'x') Is this what you wanted to happen? Probably not! The neat `allowed_to_see()` clause is completely circumvented by the "`OR ('x' = 'x')`" clause, which is always `true`. Therefore, the attacker will get to see all accounts in the database! Using the esc functions ----------------------- Here's how you can fix the problem in the example above: TX.exec( "SELECT number,amount " "FROM accounts " "WHERE allowed_to_see('" + TX.esc(userid) + "', " "'" + TX.esc(password) + "')"); Now, the quotes embedded in the attacker's string will be neatly escaped so they can't "break out" of the quoted SQL string they were meant to go into: SELECT number,amount FROM accounts WHERE allowed_to_see('user', 'x'') OR (''x'' = ''x') If you look carefully, you'll see that thanks to the added escape characters (a single-quote is escaped in SQL by doubling it) all we get is a very strange-looking password string--but not a change in the SQL statement. libpqxx-6.4.5/include/pqxx/doc/getting-started.md000066400000000000000000000116221350065432700220430ustar00rootroot00000000000000Getting started {#getting-started} =============== The most basic three types in libpqxx are the _connection_, the _transaction_, and the _result_. They fit together as follows: * You connect to the database by creating a connection object (see @ref connection). The connection type you'll usually want is `pqxx::connection`. * You create a transaction object (see @ref transaction) operating on that connection. You'll usually want the `pqxx::work` variety. Once you're done you call the transaction's `commit` function to make its work final. If you don't call this, the work will be rolled back when the transaction object is destroyed. * Until then, use the transaction's `exec` functions to execute queries, which you pass in as simple strings. * Most of the `exec` functions return a `pqxx::result` object, which acts as a standard container of rows. Each row in a result, in turn, acts as a container of fields. You can use array indexing or iterators to access either. * The field's data is stored internally as a text string. You can read it as such using its `c_str` function, or convert it to other types using its `as` and `to` member functions. These are templated on the destination type: `myfield.as();` or `myfield.to(myint);` * After you've closed the transaction, the connection is free to run a next transaction. Here's a very basic example. It connects to the default database (you'll need to have one set up), queries it for a very simple result, converts it to an `int`, and prints it out. It also contains some basic error handling. #include #include int main() { try { // Connect to the database. In practice we may have to pass some // arguments to say where the database server is, and so on. // The constructor parses options exactly like libpq's // PQconnectdb/PQconnect, see: // https://www.postgresql.org/docs/10/static/libpq-connect.html pqxx::connection c; // Start a transaction. In libpqxx, you always work in one. pqxx::work w(c); // work::exec1() executes a query returning a single row of data. // We'll just ask the database to return the number 1 to us. pqxx::row r = w.exec1("SELECT 1"); // Commit your transaction. If an exception occurred before this // point, execution will have left the block, and the transaction will // have been destroyed along the way. In that case, the failed // transaction would implicitly abort instead of getting to this point. w.commit(); // Look at the first and only field in the row, parse it as an integer, // and print it. std::cout << r[0].as() << std::endl; } catch (const std::exception &e) { std::cerr << e.what() << std::endl; return 1; } } This prints the number 1. Notice that you can keep the result object around after the transaction (or even the connection) has been closed. There are situations where you can't do it, but generally it's fine. If you're interested: you can install your own callbacks for receiving error messages from the database, and in that case you'll have to keep the connection object alive. But otherwise, it's nice to be able to "fire and forget" your connection and deal with the data. Here's a slightly more complicated example. It takes an argument from the command line and retrieves a string with that value. The interesting part is that it uses the escaping-and-quoting function `quote` to embed this string value in SQL safely. It also reads the result field's value as a plain C-style string using its `c_str` function. #include #include #include int main(int argc, char *argv[]) { try { if (!argv[1]) throw std::runtime_error("Give me a string!"); pqxx::connection c; pqxx::work w(c); // work::exec() returns a full result set, which can consist of any // number of rows. pqxx::result r = w.exec("SELECT " + w.quote(argv[1])); // End our transaction here. We can still use the result afterwards. w.commit(); // Print the first field of the first row. Read it as a C string, // just like std::string::c_str() does. std::cout << r[0][0].c_str() << std::endl; } catch (const std::exception &e) { std::cerr << e.what() << std::endl; return 1; } } You can find more about converting field values to native types, or converting values to strings for use with libpqxx, under @ref stringconversion. More about getting to the rows and fields of a result is under @ref accessing-results. If you want to handle exceptions thrown by libpqxx in more detail, for example to print the SQL contents of a query that failed, see @ref exception. libpqxx-6.4.5/include/pqxx/doc/mainpage.md000066400000000000000000000014461350065432700205220ustar00rootroot00000000000000libpqxx {#mainpage} ======= @author Jeroen T. Vermeulen @see http://pqxx.org @see https://github.com/jtv/libpqxx Welcome to libpqxx, the C++ API to the PostgreSQL database management system. Compiling this package requires PostgreSQL to be installed -- including the C headers for client development. The library builds on top of PostgreSQL's standard C API, libpq. The libpq headers are not needed to compile client programs, however. For a quick introduction to installing and using libpqxx, see the README.md file. The latest information can be found at http://pqxx.org/ Some links that should help you find your bearings: * @ref getting-started * @ref thread-safety * @ref connection * @ref transaction * @ref escaping * @ref performance * @ref transactor libpqxx-6.4.5/include/pqxx/doc/performance.md000066400000000000000000000015251350065432700212400ustar00rootroot00000000000000Performance features {#performance} ==================== If your program's database interaction is not as efficient as it needs to be, the first place to look is usually the SQL you're executing. But libpqxx has a few specialized features to help you squeeze more performance out of how you issue commands and retrieve data: * @ref streams. Use these as a faster way to transfer data between your code and the database. * @ref prepared. These can be executed many times without the server parsing and planning them each and every time. They also save you having to escape string parameters. * pqxx::pipeline lets you send queries to the database in batch, and continue other processing while they are executing. As always of course, don't risk the quality of your code for optimizations that you don't need! libpqxx-6.4.5/include/pqxx/doc/prepared-statement.md000066400000000000000000000103071350065432700225410ustar00rootroot00000000000000Prepared statements {#prepared} =================== Prepared statements are SQL queries that you define once and then invoke as many times as you like, typically with varying parameters. It's basically a function that you can define ad hoc. If you have an SQL statement that you're going to execute many times in quick succession, it may be more efficient to prepare it once and reuse it. This saves the database backend the effort of parsing complex SQL and figuring out an efficient execution plan. Another nice side effect is that you don't need to worry about escaping parameters. You create a prepared statement by preparing it on the connection (using the `pqxx::connection_base::prepare` functions), passing an identifier and its SQL text. The identifier is the name by which the prepared statement will be known; it should consist of ASCII letters, digits, and underscores only, and start with an ASCII letter. The name is case-sensitive. void prepare_my_statement(pqxx::connection_base &c) { c.prepare( "my_statement", "SELECT * FROM Employee WHERE name = 'Xavier'"); } Once you've done this, you'll be able to call `my_statement` from any transaction you execute on the same connection. For this, use the `pqxx::transaction_base::exec_prepared` functions. pqxx::result execute_my_statement(pqxx::transaction_base &t) { return t.exec_prepared("my_statement"); } Did I mention that prepared statements can have parameters? The query text can contain `$1`, `$2` etc. as placeholders for parameter values that you will provide when you invoke the prepared satement. void prepare_find(pqxx::connection_base &c) { // Prepare a statement called "find" that looks for employees with a // given name (parameter 1) whose salary exceeds a given number // (parameter 2). c.prepare( "find", "SELECT * FROM Employee WHERE name = $1 AND salary > $2"); } This example looks up the prepared statement "find," passes `name` and `min_salary` as parameters, and invokes the statement with those values: pqxx::result execute_find( pqxx::transaction_base &t, std::string name, int min_salary) { return t.exec_prepared("find", name, min_salary); } There is one special case: the _nameless_ prepared statement. You may prepare a statement without a name, i.e. whose name is an empty string. The unnamed statement can be redefined at any time, without un-preparing it first. Never try to prepare, execute, or unprepare a prepared statement manually using direct SQL queries. Always use the functions provided by libpqxx. Prepared statements are not necessarily defined on the backend right away. It's usually done lazily. This means that you can prepare statements before the connection is fully established, and that it's relatively cheap to pre-prepare lots of statements that you may or may not not use during the session. On the other hand, it also means that errors in a prepared statement may not show up until you first try to invoke it. Such an error may then break the transaction it occurs in. A performance note: There are cases where prepared statements are actually slower than plain SQL. Sometimes the backend can produce a better execution plan when it knows the parameter values. For example, say you've got a web application and you're querying for users with status "inactive" who have email addresses in a given domain name X. If X is a very popular provider, the best way for the database engine to plan the query may be to list the inactive users first and then filter for the email addresses you're looking for. But in other cases, it may be much faster to find matching email addresses first and then see which of their owners are "inactive." A prepared statement must be planned to fit either case, but a direct query will be optimised based on table statistics, partial indexes, etc. @warning Beware of "nul" bytes. Any string you pass as a parameter will end at the first char with value zero. If you pass a `std::string` that contains a zero byte, the last byte in the value will be the one just before the zero. If you need a zero byte, consider using pqxx::binarystring and/or SQL's `bytea` type. libpqxx-6.4.5/include/pqxx/doc/streams.md000066400000000000000000000044441350065432700204200ustar00rootroot00000000000000Streams {#streams} ======= Most of the time it's fine to retrieve data from the database using `SELECT` queries, and store data using `INSERT`. But for those cases where efficiency matters, there are two classes to help you do this better: `stream_from` and `stream_to`. They're less flexible than SQL queries, but you get speed and memory efficiencies in return. `stream_from` ------------- Use `stream_from` to read data directly from a database table. It's likely to be faster than a `SELECT`, but also, you won't need to keep your full result set in memory. That can really matter with larger data sets. So, use `stream_from` when you need to... * read all rows in a table, * in an arbitrary order, * without any computation done on them. You can select which _columns_ you want though, and in which order. Every row is converted to a tuple type of your choice as you read it. You stream into the tuple: pqxx::stream_from stream{ tx, "score", std::vector{"name", "points"}}; std::tuple row; while (stream >> row) process(row); stream.complete(); As the stream reads each row, it converts that row's data to your tuple, and then promptly forgets it. This means you can easily read more data than will fit in memory. `stream_to` ----------- Use `stream_to` to write data directly to a database table. This saves you having to perform an `INSERT` for every row, and so it can be significantly faster for larger insertions. As with `stream_from`, you can specify the table and the columns, and not much else. You insert tuple-like objects of your choice: pqxx::stream_to stream{ tx, "score", std::vector{"name", "points"}}; for (const auto &entry: scores) stream << entry; stream.complete(); Each row is processed as you provide it, and not retained in memory after that. The call to `complete()` is more important here than it is for `stream_from`. It's a lot like a "commit" or "abort" at the end of a transaction. If you omit it, it will be done automatically during the stream's destructor. But since destructors can't throw exceptions, any failures at that stage won't be visible in your code. So, always call `complete()` on a `stream_to` to close it off properly! libpqxx-6.4.5/include/pqxx/doc/thread-safety.md000066400000000000000000000025531350065432700215010ustar00rootroot00000000000000Thread safety {#thread-safety} ============= This library does not contain any locking code to protect objects against simultaneous modification in multi-threaded programs. Therefore it is up to you, the user of the library, to ensure that your threaded client programs perform no conflicting operations concurrently. Most of the time this isn't hard. Result sets are immutable, so you can share them between threads without problem. The main rule is: @li Treat a connection, together with any and all objects related to it, as a "world" of its own. You should generally make sure that the same "world" is never accessed by another thread while you're doing anything non-const in there. That means: don't issue a query on a transaction while you're also opening a subtransaction, don't access a cursor while you may also be committing, and so on. In particular, cursors are tricky. It's easy to perform a non-const operation without noticing. So, if you're going to share cursors or cursor-related objects between threads, lock very conservatively! Use `pqxx::describe_thread_safety` to find out at runtime what level of thread safety is implemented in your build and version of libpqxx. It returns a `pqxx::thread_safety_model` describing what you can and cannot rely on. A command-line utility `tools/pqxxthreadsafety` prints out the same information. libpqxx-6.4.5/include/pqxx/errorhandler000066400000000000000000000003011350065432700202510ustar00rootroot00000000000000/** pqxx::errorhandler class. * * Callbacks for handling errors and warnings. */ // Actual definitions in .hxx file so editors and such recognize file type. #include "pqxx/errorhandler.hxx" libpqxx-6.4.5/include/pqxx/errorhandler.hxx000066400000000000000000000051751350065432700210750ustar00rootroot00000000000000/** Definition of the pqxx::errorhandler class. * * pqxx::errorhandler handlers errors and warnings in a database session. * * DO NOT INCLUDE THIS FILE DIRECTLY; include pqxx/connection_base instead. * * Copyright (c) 2000-2019, Jeroen T.

In postgres, * it actually prevents all three. * * Third, "serializable" is only properly supported starting at postgres 9.1. * If you request "serializable" isolation on an older backend, you will get * the same isolation as in "repeatable read." It's better than the "repeatable * read" defined in the SQL standard, but not a complete implementation of the * standard's "serializable" isolation level. * * In general, a lower isolation level will allow more surprising interactions * between ongoing transactions, but improve performance. A higher level * gives you more protection from subtle concurrency bugs, but sometimes it * may not be possible to complete your transaction without avoiding paradoxes * in the data. In that case a transaction may fail, and the application will * have to re-do the whole thing based on the latest state of the database. * (If you want to retry your code in that situation, have a look at the * transactor framework.) * * Study the levels and design your application with the right level in mind. */ enum isolation_level { // read_uncommitted, read_committed, repeatable_read, serializable }; /// Traits class to describe an isolation level; primarly for libpqxx's own use template struct isolation_traits { static constexpr isolation_level level() noexcept { return LEVEL; } static constexpr const char *name() noexcept; }; template<> inline constexpr const char *isolation_traits::name() noexcept { return "READ COMMITTED"; } template<> inline constexpr const char *isolation_traits::name() noexcept { return "REPEATABLE READ"; } template<> inline constexpr const char *isolation_traits::name() noexcept { return "SERIALIZABLE"; } } #include "pqxx/compiler-internal-post.hxx" #endif libpqxx-6.4.5/include/pqxx/largeobject000066400000000000000000000003331350065432700200500ustar00rootroot00000000000000/** Large Objects interface. * * Supports direct access to large objects, as well as through I/O streams */ // Actual definitions in .hxx file so editors and such recognize file type. #include "pqxx/largeobject.hxx" libpqxx-6.4.5/include/pqxx/largeobject.hxx000066400000000000000000000524601350065432700206660ustar00rootroot00000000000000/** Large Objects interface. * * Allows access to large objects directly, or through I/O streams. * * DO NOT INCLUDE THIS FILE DIRECTLY; include pqxx/largeobject instead. * * Copyright (c) 2000-2019, Jeroen T.

In * this case, there is no way to determine whether the backend managed to * commit the transaction before noticing the loss of connection. * * In such cases, this class tries to reconnect to the database and figure out * what happened. It will need to store and manage some information (pretty * much a user-level transaction log) in the back-end for each and every * transaction just on the off chance that this problem might occur. * This service level was made optional since you may not want to pay this * overhead where it is not necessary. Certainly the use of this class makes * no sense for local connections, or for transactions that read the database * but never modify it, or for noncritical database manipulations. * * Besides being slower, it's theoretically possible that robusttransaction * actually fails more instead of less often than a normal transaction. This is * due to the added work and complexity. What robusttransaction tries to * achieve is to be more deterministic, not more successful per se. * * When a user first uses a robusttransaction in a database, the class will * attempt to create a log table there to keep vital transaction-related state * information in. This table, located in that same database, will be called * pqxxlog_*user*, where *user* is the PostgreSQL username for that user. If * the log table can not be created, the transaction fails immediately. * * If the user does not have permission to create the log table, the database * administrator may create one for him beforehand, and give ownership (or at * least full insert/update rights) to the user. The table must contain two * non-unique fields (which will never be null): "name" (of text type, * @c varchar(256) by default) and "date" (of @c timestamp type). Older * versions of robusttransaction also added a unique "id" field; this field is * now obsolete and the log table's implicit oids are used instead. The log * tables' names may be made configurable in a future version of libpqxx. * * The transaction log table contains records describing unfinished * transactions, i.e. ones that have been started but not, as far as the client * knows, committed or aborted. This can mean any of the following: * *
    *
  1. The transaction is in progress. Since backend transactions can't run * for extended periods of time, this can only be the case if the log record's * timestamp (compared to the server's clock) is not very old, provided of * course that the server's system clock hasn't just made a radical jump. *
  2. The client's connection to the server was lost, just when the client was * committing the transaction, and the client so far has not been able to * re-establish the connection to verify whether the transaction was actually * completed or rolled back by the server. This is a serious (and luckily a * rare) condition and requires manual inspection of the database to determine * what happened. The robusttransaction will emit clear and specific warnings * to this effect, and will identify the log record describing the transaction * in question. *
  3. The transaction was completed (either by commit or by rollback), but the * client's connection was durably lost just as it tried to clean up the log * record. Again, robusttransaction will emit a clear and specific warning to * tell you about this and request that the record be deleted as soon as * possible. *
  4. The client has gone offline at any time while in one of the preceding * states. This also requires manual intervention, but the client obviously is * not able to issue a warning. *
* * It is safe to drop a log table when it is not in use (ie., it is empty or all * records in it represent states 2-4 above). Each robusttransaction will * attempt to recreate the table at its next time of use. */ template class robusttransaction : public internal::basic_robusttransaction { public: using isolation_tag = isolation_traits; /// Constructor /** Creates robusttransaction of given name * @param C Connection that this robusttransaction should live inside. * @param Name optional human-readable name for this transaction */ explicit robusttransaction( connection_base &C, const std::string &Name=std::string{}) : namedclass{fullname("robusttransaction",isolation_tag::name()), Name}, internal::basic_robusttransaction(C, isolation_tag::name()) { Begin(); } virtual ~robusttransaction() noexcept { End(); } }; /** * @} */ } // namespace pqxx #include "pqxx/compiler-internal-post.hxx" #endif libpqxx-6.4.5/include/pqxx/row000066400000000000000000000003051350065432700163750ustar00rootroot00000000000000/** pqxx::row class. * * pqxx::row refers to a row in a result. */ // Actual definitions in .hxx file so editors and such recognize file type. #include "pqxx/result.hxx" #include "pqxx/row.hxx" libpqxx-6.4.5/include/pqxx/row.hxx000066400000000000000000000321751350065432700172150ustar00rootroot00000000000000/** Definitions for the pqxx::result class and support classes. * * pqxx::result represents the set of result rows from a database query. * * DO NOT INCLUDE THIS FILE DIRECTLY; include pqxx/result instead. * * Copyright (c) 2000-2019, Jeroen T.

The right way * to handle those failures is often just to re-run the transaction from * scratch. * * For example, your REST API might be handling each HTTP request in its own * database transaction, and if this kind of transient failure happens, you * simply want to "replay" the whole request, in a fresh transaction. * * You won't necessarily want to execute the exact same SQL commands with the * exact same data. Some of your SQL statements may depend on state that can * vary between retries. So instead of dumbly replaying the SQL, you re-run * the same application code that produced those SQL commands. * * The transactor framework makes it a little easier for you to do this safely, * and avoid typical pitfalls. You encapsulate the work that you want to do * into a callable that you pass to the @c perform function. * * Here's how it works. You write your transaction code as a lambda or * function, which creates its own transaction object, does its work, and * commits at the end. You pass that callback to @c pqxx::perform, which runs * it for you. * * If there's a failure inside your callback, there will be an exception. Your * transaction object goes out of scope and gets destroyed, so that it aborts * implicitly. Seeing this, @c perform tries running your callback again. It * stops doing that when the callback succeeds, or when it has failed too many * times, or when there's an error that leaves the database in an unknown * state, such as a lost connection just while we're waiting for the database * to confirm a commit. It all depends on the type of exception. * * The callback takes no arguments. If you're using lambdas, the easy way to * pass arguments is for the lambda to "capture" them from your variables. Or, * if you're using functions, you may want to use @c std::bind. * * Once your callback succeeds, it can return a result, and @c perform will * return that result back to you. */ //@{ /// Simple way to execute a transaction with automatic retry. /** * Executes your transaction code as a callback.

This can happen if the network * connection to the server is lost just while we're waiting for its reply to * a "commit" statement. The server may have completed the commit, or not, but * it can't tell you because there's no longer a connection. * * Using this still takes a bit of care. If your callback makes use of data * from the database, you'll probably have to query that data within your * callback. If the attempt to perform your callback fails, and the framework * tries again, you'll be in a new transaction and the data in the database may * have changed under your feet. * * Also be careful about changing variables or data structures from within * your callback. The run may still fail, and perhaps get run again.

This file documents building and installation of libpqxx on Windows systems. Please see the regular README.md for general instructions on building, installing, and using the library. If you are using Cygwin, MSYS, or another Unix-like environment please try the Unix configuration & build procedure instead of the one described here. Some help for the MSYS/MinGW combination is given below, but in general, things are a bit more complicated for Windows than they are for other environments. The only Windows compilers currently documented here are: Visual C++ (the newer the better) MinGW If you are using a different compiler, you should still be able to get it to work. If you do, or if you fail, please report your results so any problems can be resolved, and so that we can add support for your compiler in the standard libpqxx distribution. We'll be using the command line throughout this document. Build Environment ----------------- If you use MSYS, you may need various additional tools (such as "mktemp") installed. If you use Visual C++, make sure you have at least the 2015 version or you'll run into serious compilation trouble. You may have to make some adjustments to these instructions and scripts for the build to succeeed. If you do, let us know so we can improve the procedure. Obtaining libpq --------------- Next, make sure you have a working installation of libpq, the C-level client library included with PostgreSQL. There are two ways to make libpq available on a Windows system: Install it, or build it from sources. Either way, make sure that you get the right build: don't mix 32-bit and 64-bit libraries, or ones built for "debug" and "release." Installing libpq ---------------- The easiest way to get libpq on a Windows system, is to install PostgreSQL. The PostgreSQL installer from Windows can be obtained from http://www.postgresql.org/download/windows This build procedure has been tested against installes done by the One Click Installer. If you opt for the pgInstaller, you will have to make some adjustments to these instructions and scripts for the build to succeeed. By default, for some `{Version}` of postgres, the installer sets up libpq under: C:\Program Files\PostgreSQL\{Version}\lib Building libpq from source -------------------------- If you prefer to build libpq from source, you can compile a recent version of PostgreSQL. Its source tree should then contain libpq in binary form, as well as the corresponding headers. Look for these in src/interfaces/libpq. Visual C++ will generate separate Debug and Release versions in subdirectories called Debug and Release, respectively, at that location. Note these locations; they will become important in the next section. The source code for PostgreSQL can be obtained from http://postgresql.org/download/ Select a recent version of postgres and download the corrresponding .tar.gz or .tar.bz2 archive for that version. Unpack the sources to some directory on your computer. Select "Visual Studio Command Prompt" from the Start menu. Alternatively, open a Command Prompt window and run: VCVARSALL.BAT amd64 to prepare the environment. From the Command Prompt window, "cd" into the postgres source tree directory, and run: nmake /f win32.mak You'll also want to build a Debug-flavour libpq, so then run: nmake /f win32.mak DEBUG=1 The libpq binaries will be produced in src/interfaces/libpq/Release and src/interface/libpq/Debug, respecitively, and the Debug versions will have an extra "D" in their names. (Instructions for building PostgreSQL with MinGW are given in the MSYS section below). Preparing to Compile libpqxx ---------------------------- The rest of this text will assume that you have the libpq library in its binary form(s), as well as its header files. Now, to work on building libpqxx! You'll need to provide certain common settings: i) Copy the file `win32/common-sample` to `win32/common`, and edit the latter to reflect the paths to your PostgreSQL includes and library files: - If you compiled PostgreSQL for yourself to obtain libpq, set PGSQLSRC in win32/common to point to the "src" subdirectory in your PostgreSQL source tree. - If you installed libpq using the One Click Installer, verify that PGSQLSRC points to your specific installation of PostgreSQL. Then follow the instructions in `win32/common`. - If you obtained libpq in any other way, you may be able to build libpqxx by making the appropriate adjustments to the `common` file. ii) Create the configuration headers: `include/pqxx/config-*-*.h`. The easiest start for this is to copy from available samples. In `config/sample-headers`, find the directories most closely matching your compiler and libpq version, respectively. Take the `config-*-*.h` headers from those directories and copy them into the `include/pqxx/` directory. On a Unix-like system these headers would be generated automatically by the configure script; in the Windows case they may need some editing. How these files work is described in more detail below. iii) If you are building libpqxx from a development source tree rather than from a release distribution, you may not have the makefiles for your compiler. These makefiles should be in the `win32` directory and have names ending in ".mak": "mingw.mak," "vc-libpqxx.mak," "vc-test.mak," and so on. If you don't have these files but you do have a python interpreter, you can generate them using the template2mak.py script in the tools directory: tools/template2mak.py win32/mingw.mak.template win32/mingw.mak tools/template2mak.py win32/vc-libpqxx.mak.template win32/vc-libpqxx.mak tools/template2mak.py win32/vc-test.mak.template win32/vc-test.mak tools/template2mak.py win32/vc-test-unit.mak.template win32/vc-test-unit.mak Building libpqxx ---------------- The rest of the procedure depends on your compiler. If you're using Visual C++: 1) Select Visual Studio Command Prompt from the Start menu. Alternatively, open a Command Prompt window and run VCVARSALL.BAT amd64 to prepare the environment. Then CD into the main directory of the libpqxx source tree. Among other things it will contain the files "configure" and "Makefile.am," and subdirectories "src," "include," "win32" etc. 2) Run: "nmake /f win32/vc-libpqxx.mak ALL" to compile all dynamic, static, debug and release libraries. Once completed, you will find them in these libraries in the lib directory. The build script also copies the libpq dlls and stub libraries to the lib directory. You will have to link with these files when building applications that use libpqxx clases and methods. 3) Your version of the libpq DLL may require other DLLs in order to execute. If you installed libpq with the one click installer, these DLLs can be found in the same folder as libpq itself. The exact set of DLLs varies depending on the version of PostgreSQL that you installed. For the 9.1 version of the One Click Installer, they were: `libeay32.dll`, `libiconv-2.dll`, `libintl-8.dll`, and `ssleay32.dll`. 4) Once you have identified any additional DLLs, you should copy them to another location (perhaps the libpqxx lib folder). 5) At this point, you will no longer need to keep the postgres sources or binaries on your computer to build applications with libpqxx. If you're using MinGW (but without a Unix-like environment, see above): 1) Run `mingw32-make -f win32/MinGW.mak` 2) Consider installing a Unix-like environment like MSYS to automate all this! Running the test suite ---------------------- After building libpqxx, it is recommended that you compile and run the self-test programs included in the package. Unix, Cygwin, or MSYS users simply type "make check" to build and run the entire regression test. For Visual C++ users, the following steps should accomplish the same: 1) To build all of the self-test configurations, run: nmake /f win32\vc-test.mak ALL nmake /f win32\vc-test.mak ALL DEBUG=1 nmake /f win32\vc-test.mak ALL DLL=1 nmake /f win32\vc-test.mak ALL DLL=1 DEBUG=1 This will create four new directories: TestStaticDebug, TestStaticRelease, TestDllDebug, and TestDllRelease. Each of these folders will contain the program "runner.exe," as well as any required DLLs. 2) Make sure a PostgreSQL database is running and accessible, and set up the environment variables PGDATABASE, PGHOST, PGPORT, and PGUSER as described in the libpqxx README.md file so the test program can connect without needing to pass a connection string. 3) Run runner.exe from any of the test directories. When runner.exe runs, it executes each of the test programs in order. Some of the tests will produce lots of output, some won't produce any. Error messages that are expected in the course of a normal test run are prefixed with "(Expected)" to show that they are not harmful. All tests should complete successfully. Running the unit tests ---------------------- You may also want to compile and run the unit test programs included in the package. The procedure for doing so for Visual Studio users is nearly identical to the procedure for running the main test suite, except for the name of the .mak file, which is `win32\vc-unit.mak`. The output build directories are UnitStaticDebug, UnitStaticRelease, UnitDllDebug, and UnitDllRelease. The test application name is again runner.exe. All of these tests should complete successfully as well. Setting Up a Visual Studio Project ---------------------------------- Here's how to set up a Visual C++ project file for your own program using libpqxx (based on description by Alexandre Hanft, 2006-03-06): 1) Create a new project in the Visual C++ development environment. 2) Add your first C++ file and provide some initial code, e.g. by copying the example from the libpqxx home page. 3) Edit Project Properties, C++: Additional Include Directories. Add the location of the "include" directory found in your libpqxx source tree, e.g. `C:\src\libpqxx\include` if you keep libpqxx in `C:\src\libpqxx`. 4) Edit Project Properties, Linker: Additional Library Directories. Add the directory where your libpq and libpqxx libraries are, for example: `C:\src\libpqxx\lib` 5) Edit Project Properties, Linker, Input: Additional Dependencies. Add: libpqxx.lib. That is for your Release build. Do the same for your Debug build, but replace that "libpqxx.lib" in there with "libpqxxD.lib". 6) Your program should build successfully now. It may not be ready to run yet, because some dynamically loaded libraries are needed when starting your program. Copy the necessary libpq and libpqxx DLLs from the lib directory in your libpqxx tree, directly into your project's build directory so the system can find them when your development environment launches your program. 7) Your program should now be able to run. However, you may need to tell it how to connect to a database. If you set the environment variables PGDATABASE, PGHOST, PGPORT, and PGUSER as described in the libpqxx README.md file, your program should be able to connect without passing further parameters. 8) Once your program gets to the point where users should be able to configure it properly, change it to pass a connection string where it connects to any databases, and include your user's configuration settings. A typical connection string setting all parameters named above might look like: "dbname=testbase user=testuser host=my.dbserver.somewhere.com" 9) For any other problems, please check the project homepage as listed in the main libpqxx README.md file. Getting Started with MinGW and MSYS ----------------------------------- (Based on contribution by Michael J. Pedersen, 2004-08-17) MSYS is a Unix-like environment for Windows. Once you have this installed, building libpqxx should be a lot more like it is under Unix except that the locations of libraries and such aren't sufficiently standardized. Packages to download if you don't have them already: 1) MinGW (http://www.mingw.org/). 2) MSYS (http://www.mingw.org/). 3) w32api (http://www.mingw.org/). 4) PostgreSQL (http://www.postgresql.org/). 5) zlib (http://www.zlib.org/). It is generally recommended to get the latest versions of these packages. Compiling and installing PostgreSQL before you get to libpqxx: 1) Install MinGW (install to `c:\mingw`) 2) Install MSYS -- but not into the MinGW directory tree! 3) Run MSYS (Start -> Programs -> MinGW -> MSYS -> msys) 4) Extract, compile, and install zlib # From the main source directory of zlib: ./configure --prefix=c:/mingw/local && make && make install 5) Extract, compile, and install postgres # From the main source directory of PostgreSQL: ./configure --prefix=c:/mingw/local --with-includes=c:/mingw/local/include --with-libs=c:/mingw/local/lib make && make install 6) Extract, compile, and install libpqxx export lDFLAGS=-lws2_32 ./configure --prefix=c:/mingw/local --enable-static make && make install If you don't have and don't want to install MSYS, you won't be able to perform the "./configure" step. You can build libpqxx without it, but it takes a bit more work and doesn't build the self-test. Use the special makefile MinGW.mak in the win32 directory instead of the regular Makefile, and follow the procedure described below to use the prefabricated configuration headers enclosed in the source archive. Building libpqxx without MSYS ----------------------------- # (First set up configuration headers, see below) export LDFLAGS=-lws2_32 make -f win32/MinGW.mak # (Also install library, headers, and pkg-config on your system) Having installed libpqxx, when compiling your own programs, use the following steps (examples only here): g++ -c -o myfile.o myfile.cpp `pkg-config libpqxx --cflags` g++ -o myexec myfile.o `pkg-config libpqxx --libs` -lws2_32 Note that the linker step (g++ -o myexec) will give a spurious warning about not knowing how to use the -R flag, but the executable will still be generated, and work just fine. The last argument to that linker step MUST be `-lws2_32`. Without it, the link will provide errors about undefined references to select(). If it's not the last argument, you will get the same results. Make sure it's there, and make sure it's last. Trust me, you'll be happier. Setting up the configuration headers ------------------------------------ Several headers, normally generated by the configure script, define certain aspects of your compilation environment so that the library can work around compiler shortcomings, functions missing in older libpq versions, etc. (Samples for various compiler and libpq versions can be found in the subdirectory config/sample-headers, so if you find you need to provide these headers yourself, look there first.) Each of the aspects mentioned below is represented by a configuration item -- a preprocessor macro that is either #define'd to some value or not defined at all. Most of the items are of a Boolean nature, i.e. some feature or workaround is enabled if the corresponding macro is defined, or disabled if the macro is left undefined. Note that defining these macros to anything at all, even 0, means that the corresponding option is _enabled_. At the time of writing, there are 2 of these configuration headers that you need to concern yourself about, both of which should be created in the include/pqxx subdirectory: config-internal-compiler.h config-public-compiler.h The names contain two variables: 1. Internal or public. Configuration items that affect the compilation of your client program are located in the config-public-*.h files (currently only one file); ones that affect only the compilation of the library itself are kept in the config-internal-*.h ones and are not included at all when compiling client programs. Public configuration items are prefixed with PQXX_ to avoid clashes with macros defined by other code. 2. Autotools-related, compiler-related, or libpq-related. The autotools items are of no real interest, and the libpq section is currently empty, but the compiler one is different. The compiler-related items describe features and shortcomings of the compiler environment, such as the availability of particular headers or definitions, or the ability to compile C++ language constructs that aren't always available. The libpq items (none at the time of writing) describe what features are available in the version of libpq you're compiling against. A complete list of configuration items and their categorizations can be found in the configitems file. The normal configure script reads the list of items from include/pqxx/config.h.in and writes them to include/pqxx/config.h, then splits them up into the five smaller files as directed by the configitems database. Again, sample versions of these headers for various environments can be found in the config/sample-headers/ directory. Try copying the ones that most resemble your own environment into include/pqxx/ and, if you have any problems compiling with those, editing them by hand to enable or disable features that appear to be giving you trouble. Shared and Static Libraries, or .DLL vs. .LIB --------------------------------------------- There are two ways to build the libpqxx library: as a shared library (known in the Unix world as a Shared Object or "so," but in the Windows world as a Dynamically Loaded Library or DLL) or as a static library (whose name would end in ".a" on Unix systems but in ".LIB" on Windows systems). Linking your own applications to these types of libraries is quite similar, except with a DLL the system will also have to be able to find the library when your program is loaded--not just when you are compiling it. Unlike the situation in the Unix world, however, your choice on this point must be known as you compile your application code. With libpqxx you do this by defining the preprocessor macro PQXX_SHARED when compiling your code for use with a libpqxx DLL. Leave this definition out if you intend to link to the static version of the library. (Internally, when compiling libpqxx, this variable will also be set according to which kind of library is being built. It has a slightly different meaning in that case, but this should really only matter to you if you are helping debug the library) Similarly, you may choose to link to either the static or the shared version of libpq. The default is to use the dynamic library, which makes more sense there because libpq's API and ABI are much simpler and more stable. To build a libpqxx for use with a static libpq, however, define the preprocessor symbol PQXX_PQ_STATIC both when compiling libpqxx and while building your own application. Troubleshooting: config headers ------------------------------- The biggest typical problem for Windows/VC++ users is the need to edit the configuration headers manually, resulting usually in compile errors, e.g. for missing header files. Thus, if you get a compile error, the first places to look are the config-*-*.h and config-*-*.h files in include/pqxx. If, for instance, the error states that the header file is missing, you will find a configuration variable called PQXX_HAVE_SYS_SELECT_H, which should not be set if your system doesn't have sys/select.h. Remove the line defining this variable from the configuration header where it is defined (see the configitems file for a list of locations) and the error should disappear on the next compilation attempt. If you have to edit your configuration headers, please send your results on Github, so that headers corresponding to your environment can be included in later libpqxx releases. CAUTION: DO NOT try to unset yes/no configuration items by defining their macros to zero. A value of zero counts as "yes." If a macro is defined at all, that means "yes" (or "true," or "enabled" etc.) regardless of what actual value you set. To disable an item, make sure it is not defined at all. Troubleshooting: linking ------------------------ When you link your application to libpqxx on Windows, you may also need to link to ws2_32.lib. On Visual C++, add these in the compiler user interface under: Project Properties::Linker::Input::Additional Dependencies We recommend that you specify libpqxx_static.lib and ws2_32.lib there, in that order. libpqxx-6.4.5/win32/Makefile.am000066400000000000000000000003451350065432700162220ustar00rootroot00000000000000EXTRA_DIST = \ common-sample \ INSTALL.txt \ libpqxx.cxx \ MinGW.mak.template \ MinGW.mak \ vc-libpqxx.mak.template \ vc-libpqxx.mak \ vc-test.mak.template \ vc-test.mak \ vc-test-unit.mak.template \ vc-test-unit.mak libpqxx-6.4.5/win32/Makefile.in000066400000000000000000000307761350065432700162460ustar00rootroot00000000000000# Makefile.in generated by automake 1.15.1 from Makefile.am. # @configure_input@ # Copyright (C) 1994-2017 Free Software Foundation, Inc. # This Makefile.in is free software;
