Michael Manfre bf757a2f4d Fixed #21147 -- Avoided time.time precision issue with cache backends.
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.

Michael Manfre d5606b5763 Fixed #21146 - DatabaseCache converts expires to python value
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.

Jacob Burch 89955cc35f Fixed #9595 -- Allow non-expiring cache timeouts.
Also, streamline the use of 0 and None between cache backends.

Aymeric Augustin 83a416f5e7 Made atomic usable when autocommit is off.
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.

Aymeric Augustin 1b12e248ea Fixed #11569 -- Wrapped DatabaseCache._base_set in an atomic block.
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.

Aymeric Augustin ba5138b1c0 Deprecated transaction.commit/rollback_unless_managed.
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.

Anssi Kääriäinen cc0ac26f4a Fixed #19273 -- Fixed DB cache backend on pg 9.0+ and py3
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.
2012-11-10 19:42:20 +02:00
Claude Paroz ebc773ada3 Replaced many smart_bytes by force_bytes
In all those occurrences, we didn't care about preserving the
lazy status of the strings, but we really wanted to obtain a
real bytestring.

Russell Keith-Magee 673e6fc7fb Fixed #11675 -- Added support for the PyLibMC cache library. In order to 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.

Russell Keith-Magee 1fc7c4aee4 Fixed #14596 -- Light refactoring of the cache backends.
* Removes some code duplication,
 * Provides a convenient base class for db-like cache backends
 * Adds tests for an edge case of culling,
 * Marks the memcached tests as "skipped", rather than omitting them.

Thanks to Jonas H for the patch.

Malcolm Tredinnick fc26da645a Add warning when using cache keys that might not work with memcached.
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. Fixed #6447.

The cache tests have been failing for a long time with the db backend. This
change makes them pass again, so no test changes required here.
