Change Log

New in version 1.6.0

Though no major feature overhauls have taken place, this release is partially incompatible with 1.5.0. This stems from the fact that python-memcached is now using a flag that pylibmc has been using for some years. python-memcached uses it for a different purpose, and an incompatible one. We deemed that it would be better to support this interoperability. The change also means that Unicode strings are now stored as UTF-8 rather than pickled, which may or may not result in a slight performance improvement for this type of data.

We have also introduced a pickle_protocol behavior to enable seamless interoperability between Python 2.x and 3.x. Also, this release introduces a ManyLinux wheel, making installation a breeze on ManyLinux systems (which I suppose is many linuxes.)

New in version 1.5.0

This release fixes critical memory leaks in common code paths introduced in 1.4.2. Also fixes a critical bug in a corner of the zlib inflation code, where prior memory errors would trigger a double free. Thank you to everybody involved in the making of this release, and especially Eau de Web, without their contributions, this release and the bug fixes it contains wouldn’t have been so expedient.

New in version 1.4.0

Brace yourself, Python 3.x support has come!

Thanks to everybody involved in this project; this release involves less authors but a lot more work per person. Thanks especially to Harvey Falcic for the work he put in, without which there wouldn’t be any Python 3.x support. Also thanks to Sergey Pashinin for the initial stab at the problem.

Other than that, we had miscellaneous bug fixes, testing improvements, and documentation updates.

Last but not least I would like to ask for your support in this project, either by helping out with development, testing, documentation or anything at all; or simply by donating some magic internet money to the project’s Bitcoin address 12dveKhqiJWCY8zXT4kaHdHELXPeGAUo9h

New in version 1.3.0

Because there ain’t nothing better than releasing software in the spring time.

Lots of improvements have come about in just about every corner of the library, thanks to eighteen different authors over almost 20 pull requests. Amazing.

  • Added touch support
  • Added compress_level
  • Added weighted distribution
  • Added automated benchmarking utility
  • Added Travis CI and build status
  • Added behavior dead_timeout
  • Added behaviors tcp_keepalive

New in version 1.1

  • Removed deprecated space-based behavior names.
  • Acquire and release the GIL properly, thanks ketralnis
  • Add support for libmemcached 0.40
  • Included a more useful command-line interface
  • Fixed handling of NUL-byte keys in get_multi in binary protocol
  • Fixed some valgrind-reported memory warnings
  • Fixed bogus usage of time argument for delete.
  • 1.1.1: Fixed tests under Python 2.5

New in version 1.0

  • Lots of documentation fixes and other nice things like that.
  • Nailed what appears to be the last outstanding memory leak.
  • Explicitly require libmemcached 0.32 or newer.

New in version 0.9

  • Added a get_stats method, which behaves exactly like python-memcached’s equivalent.
  • Gives the empty string for empty memcached values like python-memcached does.
  • Added exceptions for most libmemcached return codes.
  • Fixed an issue with Client.behaviors.update.

New in version 0.8

  • Pooling helpers are now available. See pooling.rst in the distribution.
  • The binary protocol is now properly exposed, simply pass binary=True to the constructor and there you go.
  • Call signatures now match libmemcached 0.32, but should work with older versions. Remember to run the tests!

New in version 0.7

  • Restructured some of the code, which should yield better performance (if not for that, it reads better.)
  • Fixed some memory leaks.
  • Integrated changes from amix.dk, which should make pylibmc work under Snow Leopard.
  • Add support for the boolean datatype.
  • Improved test-runner – now tests build/lib.*/_pylibmc.so if available, and reports some version information.
  • Support for x86_64 should now work completely.
  • Builds with Python 2.4, tests run fine, but not officially supported.
  • Fixed critical bugs in behavior manipulation.

New in version 0.6

  • Added compatibility with libmemcached 0.26, WRT error return codes.
  • Added flush_all and disconnect_all methods.
  • Now using the latest pickling protocol.

New in version 0.5

  • Fixed lots of memory leaks, and added support for libmemcached 0.23.
  • Also made the code tighter in terms of compiler pedantics.

New in version 0.4

  • Renamed the C module to _pylibmc, and added lots of libmemcached constants to it, as well as implemented behaviors.
