* 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 <[email protected]>
* 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 <[email protected]>
* 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 <[email protected]>
* 1.51 release.
* Add a MANIFEST.in file, patch by Daniel Widerin.
Mon, 06 May 2013 07:20:21 -0600 Sean Reifschneider <[email protected]>
* 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 <[email protected]>
* 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 <[email protected]>
* 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 <[email protected]>
* 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 <[email protected]>
* 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 ":<port>".
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 <[email protected]>
* 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 <[email protected]>
* 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 <[email protected]>
* 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 <[email protected]>
* 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 marging 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 <[email protected]>
* 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 <[email protected]>
* 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 <[email protected]>
* 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 <[email protected]>
* 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 <[email protected]>
* 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 <[email protected]>
* 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 <[email protected]>
* 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 <[email protected]>
* 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 <[email protected]>
* 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 <[email protected]>
* 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 <[email protected]>
* 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 <[email protected]>
* 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 <[email protected]>
* 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 <[email protected]>
