2014-11-13Fixed #16358 - Made memcache backend delete old value on a failure to set.Michael Manfre
Default Memcached configuration allows for a maximum object of 1MB and will fail to set the key if it is too large. The key will be deleted from memcached if it fails to be set. This is needed to avoid an issue with cache_db session backend using the old value stored in memcached, instead of the newer value stored in the database.

2014-06-16Fixed #22845 -- Correctly handled memcached default timeout value.Vincent-Vega
2014-05-09Fixed #22606 -- Locmemcache has_key() failed for infinite cache expiryMalcolm Box
Refactored cache expiry logic for Locmemcache to make consistent across all places where accessed, and correctly handle None as expiry time.
2014-04-23Fixed #22495 -- Locmem cache.add() failed with infinite timeoutsMalcolm Box
cache.add() incorrectly succeeded when there was an existing key with an infinite (None) timeout.

Thanks Anssi Kääriäinen for the idea and Simon Charette for the review.
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).

import_string(). Thanks Aymeric Augustin for the suggestion and review.
2014-02-02Ensure cursors are closed when no longer needed.Michael Manfre
This commit touchs various parts of the code base and test framework. Any found usage of opening a cursor for the sake of initializing a connection has been replaced with 'ensure_connection()'.

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.
2013-09-26Fixed #21146 - DatabaseCache converts expires to python valueMichael Manfre
DatabaseCache uses raw cursors to bypass the ORM. This prevents it from being used by database backends that require special handling of datetime values. There is no easy way to test this, so no tests added.

Also, streamline the use of 0 and None between cache backends.
2013-03-13Made atomic usable when autocommit is off.Aymeric Augustin
Thanks Anssi for haggling until I implemented this. This change alleviates the need for atomic_if_autocommit. When autocommit is disabled for a database, atomic will simply create and release savepoints, and not commit anything. This honors the contract of not doing any transaction management. This change also makes the hack to allow using atomic within the legacy transaction management redundant. None of the above will work with SQLite, because of a flaw in the design of the sqlite3 library. This is a known limitation that cannot be lifted without unacceptable side effects eg. triggering arbitrary commits.
2013-03-11Fixed #11569 -- Wrapped DatabaseCache._base_set in an atomic block.Aymeric Augustin
The atomic block provides a clean rollback to a savepoint on failed writes. The ticket reported a race condition which I don't know how to test.
2013-03-11Deprecated transaction.commit/rollback_unless_managed.Aymeric Augustin
Since "unless managed" now means "if database-level autocommit", committing or rolling back doesn't have any effect. Restored transactional integrity in a few places that relied on automatically-started transactions with a transitory API.

2012-11-10Fixed #19273 -- Fixed DB cache backend on pg 9.0+ and py3Anssi Kääriäinen
There was a problem caused by Postgres 9.0+ having bytea_output default value of 'hex' and cache backend inserting the content as 'bytes' into a column of type TEXT. Fixed by converting the bytes value to a string before insert.
