zedr 6fe22b30e0 Fixed #22085 -- Added a feature for setting non-expiring keys as the default.
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).

Michael Manfre 3ffeb93186 Ensure cursors are closed when no longer needed.
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()'.

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.
2013-10-01 13:42:59 -04:00
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.

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.
2013-03-11 22:19:48 +01:00
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.

Claude Paroz 79dd751b0b Fixed #14315 -- Made memcached backend handle negative incr/decr values

Tobias McNulty for the review.
2012-11-06 12:22:42 +01:00
Alex Gaynor 335a9f9cf1 Removed many uses of bare "except:", which were either going to a) silence real issues, or b) were impossible to hit. 2012-09-07 15:08:07 -04:00
Claude Paroz ae88e73fa6 Replaced some smart_xxx by force_xxx equivalent
smart_str/smart_text should only be used when a potential lazy
string should be preserved in the result of the function call.
2012-08-30 15:46:16 +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.

Claude Paroz ac37c9e495 [py3] Encoded value before feeding it to hashlib.md5 2012-08-12 22:49:10 +02:00
Aymeric Augustin c5ef65bcf3 [py3] Ported django.utils.encoding.
* 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.

Mike Grouchy a2e927b7ed BaseCache now has a no-op close method as per ticket #18582
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
