In other projects, it is set to # `$srcdir', `$srcdir/..', or `$srcdir/../..'. # # Of course, Automake must honor this variable whenever it calls a # tool from the auxiliary directory. The problem is that $srcdir (and # therefore $ac_aux_dir as well) can be either absolute or relative, # depending on how configure is run. This is pretty annoying, since # it makes $ac_aux_dir quite unusable in subdirectories: in the top # source directory, any form will work fine, but in subdirectories a # relative path needs to be adjusted first. # # $ac_aux_dir/missing # fails when called from a subdirectory if $ac_aux_dir is relative # $top_srcdir/$ac_aux_dir/missing # fails if $ac_aux_dir is absolute, # fails when called from a subdirectory in a VPATH build with # a relative $ac_aux_dir # # The reason of the latter failure is that $top_srcdir and $ac_aux_dir # are both prefixed by $srcdir. In an in-source build this is usually # harmless because $srcdir is `.', but things will broke when you # start a VPATH build or use an absolute $srcdir. # # So we could use something similar to $top_srcdir/$ac_aux_dir/missing, # iff we strip the leading $srcdir from $ac_aux_dir. That would be: # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"` # and then we would define $MISSING as # MISSING="\${SHELL} $am_aux_dir/missing" # This will work as long as MISSING is not called from configure, because # unfortunately $(top_srcdir) has no meaning in configure. # However there are other variables, like CC, which are often used in # configure, and could therefore not use this "fixed" $ac_aux_dir. # # Another solution, used here, is to always expand $ac_aux_dir to an # absolute PATH.

stats command adjusted for better rendering; now more replication statistics info is provided. * more compact and verbose message for logging * lots of replication code clean up for more reliable electing, a new option "-n" is added that allows user to customize the votes of electing. * "memcache.py" is nearly patched for recent changes on private commands. 2008-09-04 Steve Chu * New option '-e' to set percent of the pages in the cache that should be clean, used for memp_trickle call(only available when '-T' is presented). 2008-09-03 Steve Chu * Replace the database type setting option '-T' with '-B' * Now '-T' has new meaning that it fires a separate thread to do memp_trickle every xx seconds. This feature makes the memory pool more effective by reducing too much frequent pages swapping. 2008-09-01 Steve Chu * Now 'append' and 'prepend' commands are supported. * Merge bugfix code from Memecached community. * lots of refactors for better implementation and a bit code tuning. 2008-08-28 Version 1.1.0 released 2008-08-28 Version 1.0.4 released(maitaining release) 2008-07-25 Steve Chu * Warning: 'pkget' and 'pvget' private command now has been discarded. MemcacheDB will be a more memcache protocol compatible daemon(append and prepend command will be implemented later), and will not add relational data model any more, the structural data storage will be issued by another project (now internal only). 2008-07-25 Steve Chu * Bugfix: "multiple get" did not return the right value 2008-07-23 Steve Chu * add more other replication configure parameters 2008-07-14 Steve Chu * rename "default.db" to "data.db" for less ambiguity 2008-07-04 Steve Chu * work well with Mac OS X(tested on Lepard 10.5.4) * new 'db_compact' private command to compact a btree database 2008-07-03 Version 1.1.0-beta released 2008-06-26 Steve Chu * unix socket connectivity now has be well tested. 2008-06-13 Steve Chu * some code refactoring to improve a bit performance 2008-06-11 Steve Chu * now '-b' option is a tuning way, not a limit. item size that smaller than '-b' value use fast freelist alloc, otherwise, use system 'malloc' instead. Many thanks to Davies Liu for patches and ideas. 2008-06-03 Steve Chu * new support to BerkeleyDB 4.7 - new version is BerkeleyDB 4.7 only, due to the changed bdb api - 'rep_set_request' now use time, not the number of messages * Bugfix: 'pkget' and "multiple get" that return lots of items may cause memory overflow so the daemon crashes. Thanks to Davies Liu * flooded verbose messages of bdb and replication now move to '-vv' option 2008-04-13 Steve Chu * Changes: - allow limitation to 'pkget' and 'pvget' command, use 'pkget/pvget [limit]' to get limited matched items. - 'memcache.py' is also patched for this feature. 2008-04-03 Steve Chu * New features: - add '-T' option to set database type, 'btree' or 'hash' - add '-E' option to enable second database, so we can use 'pvget' - new command 'pkget' that you can get items with a key prefix - new command 'pvget' that you can get items with a value prefix * Changes: - add support to memcache.py for 'pkget' and 'pvget' command, see 'tools/memcache.py' 2008-03-21 Version 1.0.3 released 2008-03-21 Steve Chu * Bugfix: --with-bdb can not find libdb.so and db.h 2008-03-17 Steve Chu * add a '-A' option to set page size, and also can get this value from 'stats bdb' 2008-03-07 Steve Chu * new private command 'rep_set_request' available, to set wehther it allows bulk transfer and also can get this value from 'stats rep'. See 'doc/replication.txt' * mdbtop.py update 2008-03-06 Steve Chu * new private command 'rep_set_bulk' available, to set wehther it allows bulk transfer and also can get this value from 'stats rep'. See 'doc/replication.txt' 2008-03-05 Steve Chu * add 'next_lsn' to 'stats rep' to show master-slave sync status * Make the default ack policy 'DB_REPMGR_ACKS_ONE_PEER' * upgrade 'mdbtop.py' for better rendering 2008-03-04 Version 1.0.2-beta released 2008-03-03 Steve Chu * replication configure changed and improved: - Make the default ack policy 'DB_REPMGR_ACKS_ALL_PEERS' - Make the default ack timeout 20 millisecond - two new private commands 'rep_set_ack_policy' and 'rep_set_ack_timeout' are available to set ack_policy and ack_timeout, and 'stats rep' also includes this two value. See 'docs/replication.txt' 2008-02-29 Steve Chu * give a warning if item buffer size larger than 256KB * memcache.py is patched for private commands. See 'tools/memcache.py' 2008-02-26 Steve Chu * Bugfix: incr/decr is not atomic in multithread, porting mistake from memcached 2008-02-21 Version 1.0.1-beta released 2008-02-21 Steve Chu * Bugfix: some private commands may cause seg fault 2008-02-20 Steve Chu * Bugfix: incr/decr command did not update length string 2008-02-18 Steve Chu * merge all read-only private command of replication into 'stats rep' that memcached client can read it. Original commands are still available. 'stats bdb' is also provided. * 'mdbtop.py', a new monitor tool is added for easy maintaining. See 'tools/mdbtop.py' 2008-02-14 Big Version 1.0.0-beta released 2008-02-01 Steve Chu * Almost entire code is rewritten based on Memcached 1.2.x. * More memcache protocol compatibility, now multiple get and flags are supported, also udp and unix socket is ready(not yet tested). * big performance improved due to memcached 1.2.x code base. Thread is used to resolve the blocked I/O. * use standard build tool, "./configure;make;make install" and done. * two new pravite command for replication to set/get priority. See "doc/replication.txt". 2008-01-21 Version 0.1.1 released 2008-01-21 Steve Chu * Bug fix: out string 'NOT STORED' breaks clients, it should be 'NOT_STORED'! 2007-11-05 Version 0.1.0 released 2007-10-30 Cao Kai , Steve Chu * big replication code merged, let's ship it! using option "-R" to enable replication, two private command is added for replication: db_ismaster, db_whoismaster * code refactor for performance and readability 2007-10-23 Version 0.0.4 released 2007-10-22 Steve Chu * add a new struct db_settings for all db related configures. * big code cleanup for performance. * "-L" option now uses a unit of kbytes. 2007-10-19 Cao Kai * add option "-C" and create a separate thread to do periodic checkpoint * add option "-D" and create a separate thread to do periodic deadlock detecting 2007-10-15 Novey Donar * remove the item key in data.data, about 50% db file size reduced, but not compatible with previous versions, warning to use. 2007-10-08 Steve Chu * add option "-L" to allow to set transaction log buffer * add option "-N" to allow to set DB_TXN_NOSYNC flag, if someone wanted lots of performance improved, but warning to use, because it loses transaction's durability 2007-09-29 Version 0.0.3 released 2007-09-29 Steve Chu * add command "flush_all" that will truncate a database, warning to use. * lots of code formated * Bugfix: Now using "-u" option can get proper db file mode 2007-09-21 Version 0.0.2 released 2007-09-20 Steve Chu * move some macro to memcachedb.h * rename chkpoint to db_checkpoint, for consistency. * add new command "db_archive" to remove log files that are no longer needed * README updated 2007-09-19 Steve Chu * enlarge incr value to unsigned int to conform memcache protocol, now supports max value of 4294967295. 2007-09-18 Version 0.0.1 released memcachedb-1.2.0.orig/compile0000755000175000017500000000717311055713177015174 0ustar viiruviiru#! /bin/sh # Wrapper for compilers which do not understand `-c -o'. scriptversion=2005-05-14.22 # Copyright (C) 1999, 2000, 2003, 2004, 2005 Free Software Foundation, Inc. # Written by Tom Tromey . # # This program is free software; you can redistribute it and/or modify # it under the terms of the GNU General Public License as published by # the Free Software Foundation; either version 2, or (at your option) # any later version. # # This program is distributed in the hope that it will be useful, # but WITHOUT ANY WARRANTY; without even the implied warranty of # MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

We avoid this by adding ## dummy dependencies for each header file. Too bad gcc doesn't do ## this for us directly. tr ' ' ' ' < "$tmpdepfile" | ## Some versions of gcc put a space before the `:'. On the theory ## that the space means something, we add a space to the output as ## well. ## Some versions of the HPUX 10.20 sed can't process this invocation ## correctly.

(A UDP interface is also available; details are below under "UDP protocol.") A given running memcached server listens on some (configurable) port; clients connect to that port, send commands to the server, read responses, and eventually close the connection. There is no need to send any command to end the session. A client may just close the connection at any moment it no longer needs it. Note, however, that clients are encouraged to cache their connections rather than reopen them every time they need to store or retrieve data. This is because memcached is especially designed to work very efficiently with a very large number (many hundreds, more than a thousand if necessary) of open connections. Caching connections will eliminate the overhead associated with establishing a TCP connection (the overhead of preparing for a new connection on the server side is insignificant compared to this). There are two kinds of data sent in the memcache protocol: text lines and unstructured data. Text lines are used for commands from clients and responses from servers. Unstructured data is sent when a client wants to store or retrieve data. The server will transmit back unstructured data in exactly the same way it received it, as a byte stream. The server doesn't care about byte order issues in unstructured data and isn't aware of them. There are no limitations on characters that may appear in unstructured data; however, the reader of such data (either a client or a server) will always know, from a preceding text line, the exact length of the data block being transmitted. Text lines are always terminated by \r\n. Unstructured data is _also_ terminated by \r\n, even though \r, \n or any other 8-bit characters may also appear inside the data. Therefore, when a client retrieves data from a server, it must use the length of the data block (which it will be provided with) to determine where the data block ends, and not the fact that \r\n follows the end of the data block, even though it does. Keys ---- Data stored by memcached is identified with the help of a key. A key is a text string which should uniquely identify the data for clients that are interested in storing and retrieving it. Currently the length limit of a key is set at 250 characters (of course, normally clients wouldn't need to use such long keys); the key must not include control characters or whitespace. Commands -------- There are three types of commands. Storage commands (there are six: "set", "add", "replace", "append" "prepend" and "cas") ask the server to store some data identified by a key. The client sends a command line, and then a data block; after that the client expects one line of response, which will indicate success or faulure. Retrieval commands (there are two: "get" and "gets") ask the server to retrieve data corresponding to a set of keys (one or more keys in one request). The client sends a command line, which includes all the requested keys; after that for each item the server finds it sends to the client one response line with information about the item, and one data block with the item's data; this continues until the server finished with the "END" response line. All other commands don't involve unstructured data. In all of them, the client sends one command line, and expects (depending on the command) either one line of response, or several lines of response ending with "END" on the last line. A command line always starts with the name of the command, followed by parameters (if any) delimited by whitespace. Command names are lower-case and are case-sensitive. Expiration times ---------------- Some commands involve a client sending some kind of expiration time (relative to an item or to an operation requested by the client) to the server. In all such cases, the actual value sent may either be Unix time (number of seconds since January 1, 1970, as a 32-bit value), or a number of seconds starting from current time. In the latter case, this number of seconds may not exceed 60*60*24*30 (number of seconds in 30 days); if the number sent by a client is larger than that, the server will consider it to be real Unix time value rather than an offset from current time. Error strings ------------- Each command sent by a client may be answered with an error string from the server. These error strings come in three types: - "ERROR\r\n" means the client sent a nonexistent command name. - "CLIENT_ERROR \r\n" means some sort of client error in the input line, i.e. the input doesn't conform to the protocol in some way. is a human-readable error string. - "SERVER_ERROR \r\n" means some sort of server error prevents the server from carrying out the command. is a human-readable error string. In cases of severe server errors, which make it impossible to continue serving the client (this shouldn't normally happen), the server will close the connection after sending the error line. This is the only case in which the server closes a connection to a client. In the descriptions of individual commands below, these error lines are not again specifically mentioned, but clients must allow for their possibility. Storage commands ---------------- First, the client sends a command line which looks like this: []\r\n - is "set", "add", "replace", "append", "prepend", or "cas" "set" means "store this data". "add" means "store this data, but only if the server *doesn't* already hold data for this key". "replace" means "store this data, but only if the server *does* already hold data for this key". "append" means "add this data to an existing key after existing data". "prepend" means "add this data to an existing key before existing data". The append and prepend commands do not accept flags or exptime. They update existing data portions, and ignore new flag and exptime settings. "cas" is a check and set operation which means "store this data but only if no one else has updated since I last fetched it." - is the key under which the client asks to store the data - is an arbitrary 16-bit unsigned integer (written out in decimal) that the server stores along with the data and sends back when the item is retrieved. Clients may use this as a bit field to store data-specific information; this field is opaque to the server. Note that in memcached 1.2.1 and higher, flags may be 32-bits, instead of 16, but you might want to restrict yourself to 16 bits for compatibility with older versions. - is expiration time. If it's 0, the item never expires (although it may be deleted from the cache to make place for other items). If it's non-zero (either Unix time or offset in seconds from current time), it is guaranteed that clients will not be able to retrieve this item after the expiration time arrives (measured by server time). - is the number of bytes in the data block to follow, *not* including the delimiting \r\n. may be zero (in which case it's followed by an empty data block). - is a unique 64-bit value of an existing entry. Clients should use the value returned from the "gets" command when issuing "cas" updates. After this line, the client sends the data block: \r\n - is a chunk of arbitrary 8-bit data of length from the previous line. After sending the command line and the data blockm the client awaits the reply, which may be: - "STORED\r\n", to indicate success. - "NOT_STORED\r\n" to indicate the data was not stored, but not because of an error. This normally means that either that the condition for an "add" or a "replace" command wasn't met, or that the item is in a delete queue (see the "delete" command below). - "EXISTS\r\n" to indicate that the item you are trying to store with a "cas" command has been modified since you last fetched it. - "NOT_FOUND\r\n" to indicate that the item you are trying to store with a "cas" command did not exist or has been deleted. Retrieval command: ------------------ The retrieval commands "get" and "gets" operates like this: get *\r\n gets *\r\n - * means one or more key strings separated by whitespace. After this command, the client expects zero or more items, each of which is received as a text line followed by a data block. After all the items have been transmitted, the server sends the string "END\r\n" to indicate the end of response. Each item sent by the server looks like this: VALUE []\r\n \r\n - is the key for the item being sent - is the flags value set by the storage command - is the length of the data block to follow, *not* including its delimiting \r\n - is a unique 64-bit integer that uniquely identifies this specific item. - is the data for this item. If some of the keys appearing in a retrieval request are not sent back by the server in the item list this means that the server does not hold items with such keys (because they were never stored, or stored but deleted to make space for more items, or expired, or explicitly deleted by a client). Deletion -------- The command "delete" allows for explicit deletion of items: delete
