What’s new in django-cachalot?
|
||
==============================
|
||
|
||
1.0.1
|
||
-----
|
||
|
||
- Fixes an invalidation issue discovered by Helen Warren that was occurring
|
||
when updating a ``ManyToManyField`` after executing using ``.exclude``
|
||
on that relation. For example, ``Permission.objects.all().delete()`` was not
|
||
invalidating ``User.objects.exclude(user_permissions=None)``
|
||
- Fixes a ``UnicodeDecodeError`` introduced with python-memcached 1.54
|
||
- Adds a ``post_invalidation`` signal
|
||
|
||
|
||
1.0.0
|
||
-----
|
||
|
||
Fixes a bug occurring when caching a SQL query using a non-ascii table name.
|
||
|
||
|
||
1.0.0rc
|
||
-------
|
||
|
||
Added:
|
||
|
||
- Adds an `invalidate_cachalot` command to invalidate django-cachalot
|
||
from a script without having to clear the whole cache
|
||
- Adds the benchmark introduction, conditions & results to the documentation
|
||
- Adds a short guide on how to configure Redis as a LRU cache
|
||
|
||
Fixed:
|
||
|
||
- Fixes a rare invalidation issue occurring when updating a many-to-many table
|
||
after executing a queryset generating a ``HAVING`` SQL statement –
|
||
for example,
|
||
``User.objects.first().user_permissions.add(Permission.objects.first())``
|
||
was not invalidating
|
||
``User.objects.annotate(n=Count('user_permissions')).filter(n__gte=1)``
|
||
- Fixes an even rarer invalidation issue occurring when updating a many-to-many
|
||
table after executing a queryset filtering nested subqueries
|
||
by another subquery through that many-to-many table – for example::
|
||
|
||
User.objects.filter(
|
||
pk__in=User.objects.filter(
|
||
pk__in=User.objects.filter(
|
||
user_permissions__in=Permission.objects.all())))
|
||
- Avoids setting useless cache keys by using table names instead of
|
||
Django-generated table alias
|
||
|
||
|
||

|
||
``invalidate_tables``, ``invalidate_models``, ``invalidate_all``

|
||
|
||
Fixed:
|
||
|
||
- Rewrites invalidation for a better speed & memory performance
|
||
- Fixes a stale cache issue occurring when an invalidation is done
|
||
exactly during a SQL request on the invalidated table(s)
|
||
- Fixes a stale cache issue occurring after concurrent transactions
|
||
- Uses an infinite timeout
|
||
|
