#22495: Locmem cache.add() fails with infinitely cached objects
-------------------------------------+--------------------
Reporter: boxm | Owner: nobody
Type: Bug | Status: new
Component: Core (Cache system) | Version: 1.6
Severity: Normal | Keywords:
Triage Stage: Unreviewed | Has patch: 0

-------------------------------------+--------------------
Simple test case:
{{{
from django.core.cache.backends.locmem import LocMemCache
c2 = LocMemCache("locmem", {})
In [18]: c2.set('test', 'locked', timeout=None)
In [19]: c2.add('test', 'new')
Out[19]: True
In [20]: c2.get('test')
Out[20]: 'new'
}}}
Since a timeout of None now means "cache forever", the cache.add() should
not succeed and should return False.
Memcached behaviour for comparison:
{{{
In [24]: from django.core.cache.backends.memcached import PyLibMCCache
In [25]: memcache = PyLibMCCache(server="localhost:11211", params={})
In [26]: memcache.set('test', 'locked', timeout=None)
In [27]: memcache.add('test', 'new')
Out[27]: False
}}}
