2020-12-17Fixed #29867 -- Added support for storing None value in caches.Nick Pope
Many of the cache operations make use of the default argument to the .get() operation to determine whether the key was found in the cache. The default value of the default argument is None, so this results in these operations assuming that None is not stored in the cache when it actually is. Adding a sentinel object solves this issue. Unfortunately the unmaintained python-memcached library does not support a default argument to .get(), so the previous behavior is preserved for the deprecated MemcachedCache backend.

2015-12-04Fixed #25840 -- Fixed BaseCache.get_or_set() on the DummyCache backend.Emre Yilmaz
This also fixes a possible data eviction race condition between setting and getting a key. Another thread could remove the key before get_and_set() accesses it again. In this case, now the default value will be returned instead of None.

2014-03-04Fixed #22085 -- Added a feature for setting non-expiring keys as the default.zedr
This feature allows the default `TIMEOUT` Cache argument to be set to `None`, so that cache instances can set a non-expiring key as the default, instead of using the default value of 5 minutes. Previously, this was possible only by passing `None` as an argument to the set() method of objects of type `BaseCache` (and subtypes).
2014-02-08Fixed #21674 -- Deprecated the import_by_path() function in favor of ↵Berker Peksag
import_string(). Thanks Aymeric Augustin for the suggestion and review.

2013-10-01Fixed #21147 -- Avoided time.time precision issue with cache backends.Michael Manfre
The precision of time.time() is OS specific and it is possible for the resolution to be low enough to allow reading a cache key previously set with a timeout of 0.
2013-09-10Fixed #20841 -- Added messages to NotImplementedErrorsGregor MacGregor
Thanks joseph at vertstudios.com for the suggestion.
2013-05-18Fixed #9595 -- Allow non-expiring cache timeouts.Jacob Burch
Also, streamline the use of 0 and None between cache backends.

2012-08-13[py3] Fixed encoding issues in cache key generationClaude Paroz
2012-08-07[py3] Ported django.utils.encoding.Aymeric Augustin
* Renamed smart_unicode to smart_text (but kept the old name under Python 2 for backwards compatibility). * Renamed smart_str to smart_bytes. * Re-introduced smart_str as an alias for smart_text under Python 3 and smart_bytes under Python 2 (which is backwards compatible). Thus smart_str always returns a str objects. * Used the new smart_str in a few places where both Python 2 and 3 want a str.
2012-07-18BaseCache now has a no-op close method as per ticket #18582Mike Grouchy
Also removed the hasattr check when firing request_finished signal for caches with a 'close' method. Should be safe to call `cache.close` everywhere now
2011-07-13Fixed #16225 -- Removed unused imports. Many thanks to Aymeric Augustin for ↵Jannis Leidel
the work on the patch and Alex for reviewing. git-svn-id: http://code.djangoproject.com/svn/django/trunk@16539 bcc190cf-cafb-0310-a4f2-bffc1f526a37
2010-12-21Fixed #11675 -- Added support for the PyLibMC cache library. In order to ↵Russell Keith-Magee
support this, and clean up some other 1.3 caching additions, this patch also includes some changes to the way caches are defined. This means you can now have multiple caches, in the same way you have multiple databases. A huge thanks to Jacob Burch for the work on the PyLibMC backend, and to Jannis for his work on the cache definition changes. git-svn-id: http://code.djangoproject.com/svn/django/trunk@15005 bcc190cf-cafb-0310-a4f2-bffc1f526a37

2010-11-02Fixed #14596 -- Light refactoring of the cache backends.Russell Keith-Magee

2010-09-12Add warning when using cache keys that might not work with memcached.Malcolm Tredinnick
This means testing with local dev caches (not memcache) will warn developers if they are introducing inadvertent importabilities. There is also the ability to silence the warning if a dev is not planning to use memcache and knows what they are doing with their keys. Thanks to Carl Meyer for the patch.
