py-dogpile-cache: updated to 1.1.4

1.1.4
usecase

[usecase] [memcached]
Added support for pymemcache socket keepalive and retrying client.
See also PyMemcacheBackend.socket_keepalive
PyMemcacheBackend.enable_retry_client

bug

[bug] [general]
Fixed Python 3.10 deprecation warning involving threading

1.1.3
bug

[bug] [regression] [tests]
Repaired the test suite to work with the 5.x series of the decorator module, which now appears to make use of the __signature__ attribute.
[bug] [regression]
Fixed regression where ProxyBackend was missing several methods that were added as part of the 1.1 release.

1.1.2
feature

[feature] [region]
Added new region method CacheRegion.key_is_locked(). Returns True if the given key is subject to the dogpile lock, which would indicate that the generator function is running at that time. Pull request courtesy Bastien Gerard.

[feature] [memcached]
Added support for the pymemcache backend, using the "dogpile.cache.pymemcache" backend identifier. Pull request courtesy Moisés Guimarães de Medeiros.

1.1.1
bug

[bug] [region]
Fixed regression where the serialization and deserialization functions could be inadvertently turned into instance methods with an unexpected argument signature, namely when pickle.dumps and pickle.loads are the pure Python version as is the case in pypy.

1.1.0
feature

[feature] [region]
Reworked the means by which values are serialized and deserialized from backends, and provided for custom serialization of values. Added the CacheRegion.serializer and CacheRegion.deserializer parameters which may be set to any serializer.
Serialization and deserialization now take place within the CacheRegion so that backends may now assume string values in all cases. This simplifies the existing backends and also makes custom backends easier to write and maintain.
Additionally, the serializer is now applied to the user-defined value portion of the CachedValue and not to the metadata or other portions of CachedValue object itself, so the serialized portion is effectively a “payload” within the larger CachedValue structure that is passed as part of the larger string format. The overall format is a separate JSON of the cached value metadata, followed by the serialized form. This allows for end-user serialization schemes that are hardwired to the values themselves without the need to serialize dogpile’s internal structures as well.
Existing custom backends should continue to work without issue; they now have the option to forego any separate serialization steps, and can also subclass a new backend BytesBackend that marks them as a backend that only deals with bytes coming in and out; all internal serialization logic from such a backend can be removed.
Pull request courtesy Alessio Bogon.

misc

[change]
Added pep-484 annotations to most of the dogpile.cache package.

1.0.2
feature

[feature] [memcached]
Added support for TLS connections to the bmemcached backend. Pull request courtesy Moisés Guimarães de Medeiros.
bug

[bug] [installation]
Repaired the setup.cfg file so that the source and wheel distributions will not add the “tests” directory to the Python environment. Pull request courtesy Michał Górny.

1.0.1
bug

[bug] [install]
dogpile.cache 1.0.0 was released with a minimum Python version of 3.5. However, due to a dependency issue, the minimum version is now Python 3.6. The 1.0.0 release will be removed from PyPI so that Python versions prior to 3.6 will continue to make use of the previous dogpile.cache 0.9.2.

[bug] [installation]
Removed the “universal=1” directive from setup.cfg as this would create py2/py3 wheels. dogpile 1.0.x is Python 3 only so a py3-only wheel is now created.

1.0.0
feature

[feature]
Improved plugin scanner performance by switching from pkg_resources to stevedore.
[feature] [redis]
Added support for Redis Sentinel. Pull request courtesy Stéphane Brunner. See RedisSentinelBackend.

misc

[change: py3k]
For version 1.0.0, dogpile.cache now supports Python 3.5 and above only.
