Releases for Memcache API and Integration

Release notes

Since 7.x-1.0-rc3 there have been no reported regressions, so we're releasing 7.x-1.0 today.

This is the same code as rc3, so see the release notes for changes since 7.x-rc2.

If you are using 7.x-0.2 or a previous 7.x-1.x release candidate prior to 7.x-1.x-rc3 you are strongly urged to upgrade, several major bugs have been fixed since those releases.

Note that sessions are not fully ported to 7.x yet, and session.inc has been moved to an unstable folder for this reason. If you're using memcache sessions in 7.x, we'd suggest sticking with core's database sessions for now.

Final checks and benchmarking of this release were sponsored by ITV and carried out by Tag1 Consulting.

Thanks to das-peter and berdir for extensive testing and patching of the 7.x-1.x branch.

Release notes

Release notes

Bug fix and testing release.

We're also moving to a new numbering scheme. Memcache for Drupal 7 has around the same stability and feature set as memcache 6.x-1.8, it is lagging behind 6.x-1.9 by a few commits. However it has been in production on some sites for more than a year (at least cache and lock backends), so it makes sense to cut a stable release at this point.

The 7.x-0.x series will be pure bug fix and testing releases.

Once we start adding the new features added in 6.x-1.9 we'll switch back to a 7.x-1.x numbering scheme, with the eventual plan to have the 6.x-1.x and 7.x-1.x branches completely in sync with each other (apart from changes to the core API etc.).

The session back end is not as well tested for 7.x and there are outstanding major bugs with the database back end in core, so post bug reports if you find them.

Changes since 7.x-1.0-beta4:

Release notes

This is a significant release for memcache, including new simpletests, critical bug fixes, performance improvements and new features. Thanks to Acquia for sponsoring this release!

It has had significant regression testing compared to previous memcache releases, however as with any new release of a contributed module, be sure to test in your development and/or staging environments before deploying to production.

Should you discover any bugs or regressions, please check known issues before reporting.

The 'upgrade path' has been tested between 6.x-1.8 and 6.x-1.9, no changes should be necessary to your configuration to upgrade between those versions. If you have both the memcached and memcache PECL extensions installed, 1.9 will now default to the memcache extension due to several known, unresolved issues with the PECL memcached extension, however this is configurable in settings.php now.

There are some other new configuration options available with this release, check README.txt for documentation.

We now also ship a memcache module in addition to the memcache_admin module, this entirely optional for the moment and doesn't do much, however you will need to install it if you want to run the simpletests.

Release notes

If using memcache 6.x-1.6 or 6.x-1.7, it is highly recommended that you upgrade to 6.x-1.8 which solves some known cache flushing bugs.

If you are upgrading from versions prior to 6.x-1.6 to 6.x-1.8, it is possible that some items cleared with a wildcard flush will no longer be treated as invalid. You may want to flush memcache or run drush cc all to correct this.

If you are using memcache.db.inc, we HIGHLY recommend you switch to using memcache.inc, as memcache.db.inc is no longer supported and will likely be removed in future 6.x releases.

Features:

• Memcache locking implementation [link]
• #961434: Improve stats by reporting delete success or failure
• #959200: Add ability to exclude bins (tables) from memcache

Bug fixes:

• #958930: Performance of 6.x-1.7 still degraded compared to 6.x-1.5 addressed known performance issues
• #961474: Don't allow reset via stats pages
• #538042: cache_set duplicated keys error. NOTE: memcache.db.inc is deprecated and should not be used
• #961496: Deprecate memcache.db.inc NOTE: memcache.db.inc may be removed completely in future 6.x releases

Release notes

Fixes DRUPAL-SA-CONTRIB-2010-098.

Changes since DRUPAL-7--1-0-BETA1:

Release notes

This release offers two major new features: It is now possible to flush only part of a bin within memcache (meaning that you no longer have to configure multiple bins), and the memcache module now supports both the older memcache PECL extension, and the newer memcached PECL extension. Your PECL extension is automatically detected, no configuration is necessary.

Features:

#493448: Memcache and cache_clear_all wildcard
#775498: Support use of PECL memcached
Bugs:

#525400: long keys get truncated
#541136: Notice: Undefined property $expire in dmemcache.inc on line 74
#580372: Notice: Undefined index: cache
#810306: Debugging slipped into -rc release

Release notes

Beta release of the memcache module for Drupal 7.

This is primarily a direct port of the memcache module from Drupal 6 to Drupal 7. This version of the module supports the newer memcached PECL extension as well as the older memcache PECL extension.

Still known to not work:

• Sessions in memcache (memcache-session.inc)
• Database-backed memcache caching (memcache.db.inc)
