Dogpile.cache

Released: Wed Apr 26 2023
feature


- **[feature] [region]** Added new construct `api.CantDeserializeException` which can be
raised by user-defined deserializer functions which would be passed to
`CacheRegion.deserializer`, to indicate a cache value that can't
be deserialized and therefore should be regenerated. This can allow an
application that's been updated to gracefully re-cache old items that were
persisted from a previous version of the application. Pull request courtesy
Simon Hewitt.

Released: Fri Jul 8 2022
bug


- **[bug] [memcached]** Moved the `MemcacheArgs.dead_retry` argument and the
`MemcacheArgs.socket_timeout` argument which were
erroneously added to the "set_parameters",
where they have no effect, to be part of the Memcached connection
arguments `MemcachedBackend.dead_retry`,
`MemcachedBackend.socket_timeout`.

rel_1_1_6

Released: Fri Jun 10 2022
usecase


- **[usecase] [redis]** Added `RedisBackend.connection_kwargs` parameter, which is a
dictionary of additional keyword arguments that will be passed directly to
`StrictRedis()` or `StrictRedis.from_url()`, in the same way that this
parameter works with the `RedisSentinelBackend` already.
