Sun, 14 Jan 2024 08:49:00 -0700 Sean Reifschneider * Fix some docstring typos (Christian Clauss PR #192) * delete() return value now is 1 for "DELETED" and 0 for "NOT_FOUND" or server error. (Nick Pope PR #190) * Removed obsolete configuration for Travis CI. (Nick Pope PR #189) Thu, 28 Dec 2023 19:24:00 -0700 Sean Reifschneider * 1.61 release. * Fixing the ChangeLog entry which had a bad date. Sun, 24 Dec 2023 22:33:47 -0700 Sean Reifschneider * 1.60 release. * Allow to use a datetime.timedelta parameter for Client.set (PR from Theo Massard) * Fix cmemcahe_hash 0 values being translated to 1 (PR from Chow Loong Jin) * Fix tuple key support in multi methods (PR from Sergii Mikhtoniuk) #154 * Add support for default value in get (PR from Jakub Szafrański) * test_memcache.py: try import unittest.mock (PR from Tim Orling) * Use == as suggested by Python 3.8 (PR from @za) * Decoding in slab funcs, replacing "1" with "True" in while. #175 * Tell PyPI to parse README as markdown (PR from @MartinThoma) #168 * test_memcache.py: try import unittest.mock (PR from @moto-timo) #172 * Removed Python 2.7 from setup.cfg, adding 3.8-3.12 * Add support for default value in get() (PR from @samupl) #158 * Fix tuple key support in multi methods (regression in 1.55). (PR from @sergiimk) #155 * Fix cmemcahe_hash 0 values being translated to 1. For example "ob" would hash to 0 and then get converted to 1. Looks like this dated back to 2009, the original code we imported for that hash function. (PR from @hyperair) #152 * Removing six.PY2/3 conditionals * Removing "time" from delete and making expiry mandatory in touch. (port of @erankor's PR in #30 ) * Added quit() method. This method sends the 'quit' command to the servers and then closes the connections, reducing the number of TIME_WAIT sockets hanging around the OS. (PR from @userrl) #15 * Allow to use a datetime.timedelta parameter for Client.set (PR from @tbobm) #146 * Allow keys to be encoded before use. (Port of PR in #52 from @harlowja) * Removing historic python 2to3 code and deprecated socket.error (for OSError).

Patch by edmorley #86 * Support for "stats slabs". Patch by grg350 #93 * get_stats encoding fix. Patch by bartTC #91 * Pin Six version to >= 1.4 Patch by pipermirriam #81 * setup.py build process pulls version from memcached.py Patch by dieselmachine #72 * delete() and delete_multi() now default the "time" argument to None, since the protocol doesn't allow a time in some implementations. Patch by oremj #27 Fri, 31 Jul 2015 11:38:25 -0600 Sean Reifschneider * 1.57 release. * Fix for #75 and #76, mc.set(key, False) results in "ValueError: invalid literal for int()". Reported by Carlos Sanchez on github. Sun, 26 Jul 2015 14:44:20 -0600 Sean Reifschneider * 1.56 release. * More patches for python3 from Victor Stinner #67. Thanks! * Tests moved out into their own unittest testcases. Patch by Jeremy Thurgood. * Adding support for pluggable compressors. Patch by cactus on github. * Adding support for "noreply". Patch by cactus on github. * Allowing empty key in _multi() calls. Suggested by sergio97 on github. Sun, 21 Sep 2014 13:41:30 -0600 Sean Reifschneider * 1.54 release. * Numerous patches to attempt to get Python 3 working, but tests are still failing under Python 3, so this code is not ready yet. * MemcachedKeyCharacterError better describes key problem. Suggested by Roy Smith * Added touch(), patch by erankor on github. * Allow empty server list, patch by zewt on github. * If unknown flags in get request, raises a value error rather than the code bombing out. * Setting the SERVER_MAX_* values after import did not work, despite being documented to. Reported by alexf101 on github. Sun, 07 Jun 2013 11:12:18 -0600 Sean Reifschneider * 1.53 release. * Fixing set_multi() so that if the server closes the connection it will no longer raise AttributeError. Issue found and resolution reviewed by Ben Hoyt. * readline() now will mark the connection dead if the read fails. It was just closing it before. This is related to the set_multi() change but worth noting separately. Thanks to Ben Hoyt. * Discussion of the above: https://github.com/linsomniac/python-memcached/commit/b7054a964aed0e6d86e853e60aab09cd0183b9f6#commitcomment-3337557 Sun, 02 Jun 2013 01:08:26 -0600 Sean Reifschneider * 1.52 release. * Changing check_keys to use re.match() instead of str.translate(), because re.match() works with Python < 2.6. Found by Giovanni Di Milia. Mon, 06 May 2013 15:29:07 -0600 Sean Reifschneider * 1.51 release. * Add a MANIFEST.in file, patch by Daniel Widerin. Mon, 06 May 2013 07:20:21 -0600 Sean Reifschneider * 1.50 release. * Client() now takes a "check_keys" option, which defaults to True. If False, it disables the checking of keys to ensure they have acceptable size and are composed of non-control characters. Suggested by Ben Hoyt. * Converting control character checking of keys based on performance testing of alternatives by Ben Hoyt. * Converted unicode tests from using u'', patch from Eren Güve. * Included license file (pull request by "Philippe" pombredanne). * Doing a "set" after server goes away, raised AttributeError: 'NoneType' object has no attribute 'sendall'. Patch by Ken Lalonde * incr/decr return None instead of 0 on server connection failure. Suggested by Ivan Virabyan * Supports IPv6 connections using: "inet6:[fd00::32:19f7]:11000". Patch by Romain Courteaud * Switching over to github for this project: https://github.com/linsomniac * Bug #974632: _ConnectionDeadError sometimes was escaping the get/set code. This should return to readline() not raising an exception, except in the case that it's called from the get/set(). Report from Gary Poster, proposed patch by Brad Crittenden. Misc fixes by Brad Crittenden: fixing a docstring, if "port" is set to any false-like value it will default to 11211. Mon, 29 Nov 2011 12:37:32 -0700 Sean Reifschneider * Bug #887765: Interrupted connection to memcache server can cause inconsistencies. Added "flush_on_reconnect" (defaults to off) to Client() which will cause a client that has lost connection to a server and then reconnects to flush the cache on the reconnect so that it doesn't get old values from that server. Patch by Daniel Benamy. Sun, 27 Nov 2011 18:15:32 -0700 Sean Reifschneider * Bug #745633: Values of maximum size are not stored API inconsistency, max value length was tested for <= while max KEY length was <. So I picked that keys and values *LONGER* than the specified max value are what is used, and added documentation and tests to that effect. The test for max value tested that length plus 4, so I've changed that to be that value plus 1. Issue found by matt-quru. * Bug #713488: Issues Invalid "delete" command. Protocol has changed so that the "delete" operation no longer takes a "time" argument. It seems that some servers will refuse a "delete key 0" while others will accept it, but the official server will NOT accept "delete key 1". So I've changed it so that if no "time" argument is specified, no time argument is sent to the server. * Bug #713451: server.expect("END") needs to be in a finally block Expect an "END" when the _recv_value() raises an exception. Patch by Jay Farrimond. * Bug: #741090: cas cache can grow unbounded. Default now is that the cache is not used, unless the "Client()" object is created with "cache_cas=True". In that case, you need to have your own cas clearing code, a simple one would be to use Client().reset_cas() to completely clear the cas_ids cache. Problem pointed out by Shaun Cutts. * Bug #728359: Make python-memcache work on memcache restarts. Patch by Tarek Ziade', reviewed and further patches submitted by Hugo Beauze'e-Luysse and Neganov Alexandr. * Bug #798342: If memcached server sends unknown flag in response for "get", results in: "UnboundLocalError: local variable 'val' referenced before assignment" Now returns "None" instead. Patch by Sharoon Thomas Mon, 20 Dec 2010 19:14:17 -0700 Sean Reifschneider * Bug #680359: useOldServerHashFunction() is broken. It now correctly switches back to the old memcache hash function. Thu, 16 Dec 2010 02:07:40 -0700 Sean Reifschneider * Bug #471727: Changed the delete() code to explicitly check for both NOT_FOUND and DELETED as the responses and return successful for both. It also logs an error if one of these two responses is not found. Also added a test to ensure that delete() works. * When using set_multi and one value is too big, traceback TypeError: 'int' object is unsubscriptable Patch by Orjan Persson * Fixing Bug #529855: Server host can now be bare host without ":". Fix proposed by Roger Binns. * Fixing Bug #491164: Typo fix, "compession" -> "compRession". * Fixing Bug #509712: "TypeError: 'NoneType' object is unsubscriptable" Also fixed some other similar code to not have issues with that. * Also related to 509712 and 628339: readline() now returns '' instead of None when a server dies. This should be safer. Patch suggested by Denis Otkidach. * Fixing Bug #628339: Read from server sometimes fails. Patch by Jeremy Cowles. * Fixing Bug #633553: Add stat arguments support to get_stats(). Patch by Ryan Lane. * Changing the license to the PSF License. * Removing Evan's e-mail address at his request, changing authorship to Sean. Sat, 28 Nov 2009 01:07:42 -0700 Sean Reifschneider * Version 1.45 * Per-connection max server key length. Patch by Nicolas Delaby * Patches to make memcached more garbage-collectable. Removes "debugfunc" argument from _Host objects and changed to "debug" boolean. Patches by John McFarlane and Aryeh Katz. * Switching to a cmemcache compatible hash function. Implemented by André Cru and Ludvig Ericson. To switch back to the old style, use: memcached.useOldServerHashFunction() * Rejecting keys that have spaces in them. Patch by Etienne Posthumus. * Fixing exception raising syntax. Patch by Samuel Stauffer. * Optimizations in read code. Patch by Samuel Stauffer. * Changing classes to be newstyle. Patch by Samuel Stauffer. * Changed "has_key" to "in". Patch by Samuel Stauffer. * incr/decr were raising ValueError if the key did not exist, the docstring said it returned none. Patch by Chihiro Sakatoku. * Adding cas method, submitted by Ben Gutierrez. * Fix in the docstring for how to use the "set" method. Found and fixed by William McVey Thu, 02 Apr 2009 13:37:49 -0600 Sean Reifschneider * Version 1.44 * Allowing spaces in the key. (Patch provided by xmm on Launchpad) * Detecting when the pickler needs a positional argument. (Patch provided by Brad Clements on Launchpad) * Moving length check after the compression. (Patch provided by user Tom on Launchpad) * Fixing arguments passed to the _Error if invalid read length. * Fixing the representation of domain sockets. (Patch provided by user MTB on Launchpad) * Changing a typo of dead_until. (Patch provided by Shane R. Spencer) * Providing better error messages (patch provided by Johan Euphrosine). * Adding get_slabs() function to get stats. (Patch provided by Nick Verbeck) Sun, 01 Jun 2008 15:05:11 -0600 Sean Reifschneider * Version 1.43 * eliott reported a bug in the 1.42 related to the socket timeout code causing a traceback due to the timeout value not being set. Sat, 31 May 2008 02:09:17 -0600 Sean Reifschneider * Version 1.42 * Paul Hummer set up a Launchpad project which I'm going to start using to track patches and allow users to set up their own bzr branches and manage merging in the upstream patches with their own. https://launchpad.net/python-memcached * Patch from Jehiah Czebotar which does: Changing the calls to mark_dead() to make them dereference tuples, reducing timeout on sockets to 3 seconds, settable via setting Host._SOCKET_TIMEOUT. * Patches from Steve Schwarz for set_multi() to return the full set of keys if all servers are down. Previously would not report any keys. * Fix from Steve Schwarz delete_multi() argument "seconds" not being correctly handled. Changed it to "time" to match all other calls. * Patch from Peter Wilkinson to support using unix domain sockets. He reports that tests succeed with with memcached daemons running, the normal and a domain socket started via "memcached -s memcached.socket". I massaged it quite a bit. To use domain sockets, use a connect string of "unix:/path/to/socket" Note however that if you are using a host name of "unix", it will now detect "unix:11211" as being a domain socket with the name "11211". In this case, please use "inet:unix:11211". Because of this, it is now preferred to use a connect string prefix of "inet:" or "unix:". Tue, 29 Apr 2008 21:03:53 -0600 Sean Reifschneider * Version 1.41 * Patch from Jehiah Czebotar to catch an additional server disconnect situation. * Patch from Andrey Petrov to add the "append" and "replace" commands. Tue, 18 Sep 2007 20:52:09 -0600 Sean Reifschneider * Version 1.40 * Updated setup.py file that uses distutils provided by Kai Lautaportti. * Prevent keys from containing ASCII character 127 as well, patch provided by Philip Neustrom. * Added ability to overload the persistent_load/id, patch provided by Steve Schwarz. * Fixed ability to pass (server_hash,key) in place of key in Client.set() Reported by Alexander Klyuev. Tue, 14 Aug 2007 14:43:27 -0600 Sean Reifschneider * Version 1.39 * Michael Krause reports the previous version doesn't work for _val_to_store_info() calls because it's defined as a staticmethod. Removing staticmethod decorator. Also confirmed by Kai Lautaportti, with suggested fix of removing staticmethod. Fri, 10 Aug 2007 17:50:13 -0600 Sean Reifschneider * Version 1.38 * Matt McClanahan submitted a patch that allow add() to have a min_compress_len argument. * Steve Schwarz submitted a patch allowing user-defined picklers. * Michael Krause suggested checking the return value to prevent an exception from being raised in _set() when a value is too large to be stored. Fri, 27 Jul 2007 01:55:48 -0600 Sean Reifschneider * Version 1.37 * Fixing call from add() to _set() with parameter for min_compress_len. Reported by Jeff Fisher. Thu, 07 Jun 2007 04:10:31 -0600 Sean Reifschneider * Version 1.36 * Patch by Dave St.Germain to make the Client() class sub-class threadlocal to help with multi-threading issues. Only available in Python 2.4 and above. * Patch by James Robinson with: 1) new set_multi method. 2) factored out determining the flags, length, and value to store from set() into method _val_to_store_info() for use by both set() and set_multi(). 3) send_cmds() method on host which doesn't apply the trailing '\r\n' for use by set_multi. 4) check_key() extended a bit to allow for testing the prefix passed to set_multi just once, not once per each key. 5) Patch also enables support for auto compression in set, set_multi, and replace. * Suggestion by Helge Tesdal, fixes in check_key for non-string keys. * NOTE: On a farm of clients with multiple servers, all clients will need to be upgraded to this version. The next patch changes the server hash. * Philip Neustrom supplied a patch to change the server hash function to binascii.crc32. The original "hash()" call is not cross-platform, so big and little endian systems accessing the same memcache may end up hitting different servers. Restore the old functionality by calling: "memcached.serverHashFunction = hash" after importing memcache. * Philip Neustrom points out that passing Unicode keys or values causes problems because len(key) or len(value) is not equal to the number of bytes that are required to store the key/value. Philip provides a patch which raises an exception in this case. Raises memcache.Client.MemcachedStringEncodingError exception in this case. * NOTE: If you recompiled memcached to increase the default 1MB max value size, you will need to call "memcached.MAX_SERVER_VALUE_LENGTH = N" or memcached will not store values larger than the default 1MB. * Philip Neustrom includes another patch which checks that the key doesn't exceed the memcache server's max size. If it does, the item is silently not stored. * Philip Neustrom added a bunch of sanity checks. * Jehiah Czebotar provided a patch to make the add() and replace() functions return 0 when the add or replace fails, similar to how set() works. Sat, 16 Sep 2006 18:31:46 -0600 Sean Reifschneider * Version 1.34 * In get_multi, if the recv loop reads 0 bytes, raising an EOFError. Identified by Jim Baker. Tue, 05 Sep 2006 14:06:50 -0600 Sean Reifschneider * Version 1.33 * Including patch from Yoshinori K. Okuji to read in larger chunks for readline() calls. This should dramatically improve performance under some circumstances. Sun, 03 Sep 2006 14:02:03 -0600 Sean Reifschneider * Version 1.32 * Including patch from Philip Neustrom which checks keys sent to the server for length and bad characters. Sat, 20 May 2006 14:51:28 -0600 Sean Reifschneider * Version 1.31 * Rolled version 1.30 since the Danga folks are now listing this version as the official version. Removing the "tummy" from the version number, and incrementing so that it's clear it's more recent than "1.2". * Patch applied from Simon Forman for handling of weighted hosts. * Added a little more meat to the README. Sat, 28 Jan 2006 15:59:50 -0700 Sean Reifschneider * cludwin at socallocal suggested that the write-combining with sendall() may not be beneficial. After testing on both SMP and non-SMP machines, I can't see a significant benefit to not doing the write-combining, even on large strings. The benefits of write-combining on smaller strings seems to be significant on UP machines in tight loops. Even on strings that are larger than 2MB, there seems to be no benefit to splitting out the writes. Sun, 18 Sep 2005 18:56:31 -0600 Sean Reifschneider * Changing a printf to debuglog and catching a pickle exception, patch submitted by Justin Azoff. Thu, 14 Jul 2005 11:17:30 -0700 Sean Reifschneider * Alex Stapleton found that the sendall call was slow for writing data larger than several kilobytes. I had him test a change to his patch, which worked as well, but was simpler. The code now does two sendall calls, one for the data and one for the line termination, if the data is larger than 100 bytes. Thu, 7 Apr 2005 14:45:44 -0700 Sean Reifschneider * Incorporating some fixes to get_multi() from Bo Yang Mon, 13 Dec 2004 02:35:17 -0700 Sean Reifschneider * Simplifying the readline() function and speeding it up ~25%. * Fixing a bug in readline() if the server drops, mark_dead() was not being properly called. Sun, 12 Dec 2004 18:56:33 -0700 Sean Reifschneider * Adding "stats()" and "flush_all()" methods. Thu, 10 Aug 2003 12:17:50 -0700 Evan Martin * Slightly more verbose self-test output. * Fix mark_dead() to use proper classname. * Make pooltest.py run from the test directory. Thu, 07 Aug 2003 16:32:32 -0700 Evan Martin * Add incr, decr, and delete. * Better Python (based on comments from Uriah Welcome). * Docs, using epydoc. Thu, 07 Aug 2003 14:20:27 -0700 Evan Martin * Initial prerelease.
