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.

2020-12-09Fixed #32193 -- Deprecated MemcachedCache.Mariusz Felisiak
2020-12-08Fixed #32233 -- Cleaned-up duplicate connection functionality.Florian Apolloner
2020-12-07Refs #21012 -- Removed unnecessary _create_cache() hook.Florian Apolloner
This removes unused (since d038c547b5ce585cbf9ef5bb7e5298f52e4a243b) workaround to load a cache backend with its dotted import path and moves remaining logic to the CacheHandler. Thanks Tim Graham for the review.

2020-09-02Refs #29887, Refs #24212 -- Added servers configuration hook for memcached ↵Nick Pope
backends. The servers property can be overridden to allow memcached backends to alter the server configuration prior to it being passed to instantiate the client. This allows avoidance of documentation for per-backend differences, e.g. stripping the 'unix:' prefix for pylibmc.

backends.
2020-06-22Fixed #31728 -- Fixed cache culling when no key is found for deletion.Guillermo Bonvehí
DatabaseCache._cull implementation could fail if no key was found to perform a deletion in the table. This prevented the new cache key/value from being correctly added.

Removed usage of urllib.quote(), unnecessary since cbbe60c7fc39fa8ff75554bd90104eaad6924bb1. Used hasher's .update() on key fragments.

2018-01-24Fixed #28977 -- Changed local-memory cache to use LRU culling.Grant Jenks
LRU culling turns every read into a kind of write to the cache: cache keys are moved to the first position in the OrderedDict when they are retrieved. The RWLock which permitted multiple readers while prioritizing a single writer is obsolete since all accesses are now writes.
