Release Notes

tkem/cachetools (cachetools)

v7.0.5

Compare Source

===================

• Minor @cachedmethod performance improvements.

v7.0.4

Compare Source

===================

• Fix and properly document @cachedmethod.cache_key behavior.

• Minor documentation improvements.

v7.0.3

Compare Source

===================

• Fix DeprecationWarning when creating an autospec mock with
  @cachedmethod decorations.

v7.0.2

Compare Source

===================

• Provide more efficient clear() implementation for all support
  Cache classes (courtesy Josep Pon Farreny).

v7.0.1

Compare Source

===================

• Various test improvements.

• Update Copilot Instructions.

v7.0.0

Compare Source

===================

• Require Python 3.10 or later (breaking change).

• Drop support for passing info as fourth positional parameter to
  @cached (breaking change).

• Drop support for cache(self) returning None with
  @cachedmethod (breaking change).

• Convert the @cachedmethod wrappers to descriptors, deprecating
  its use with class methods and instances that do not provide a
  mutable __dict__ attribute (potentially breaking change).

• Convert the previously undocumented @cachedmethod attributes
  (cache, cache_lock, etc.) to properties for instance
  methods, providing official support and documentation (potentially
  breaking change).

• Add an optional info parameter to the @cachedmethod
  decorator for reporting per-instance cache statistics. Note that
  this requires the instance's __dict__ attribute to be a mutable
  mapping.

v6.2.6

Compare Source

===================

• Improve typedkey performance.

• Minor documentation improvements.

• Minor testing improvements.

• Minor code readability improvements.

v6.2.5

Compare Source

===================

• Improve documentation regarding @cachedmethod with lock
  parameter.

• Add test cases for cache stampede scenarios.

• Update CI environment.

v6.2.4

Compare Source

===================

• Fix license information displayed on PyPI be using an updated
  version of twine for uploading.

v6.2.3

Compare Source

===================

• Improve documentation regarding @cachedmethod with condition
  parameter.

• Minor style and readability improvements.

• Modernize build environment.

• Update CI environment.

v6.2.2

Compare Source

===================

• Minor improvements from GitHub Copilot code review.

• Improve documentation.

v6.2.1

Compare Source

===================

• Add support for Python 3.14.

• Improve documentation.

• Update CI environment.

v6.2.0

Compare Source

===================

• Improve general RRCache performance by storing cache keys in an
  additional sequence container. Note that this will increase memory
  consumption.

• Add more unit tests.

v6.1.0

Compare Source

===================

• Improve LFUCache insertion performance by switching to an
  implementation based on the cacheing <https://pypi.org/project/cacheing/>_ library.

• Update CI environment.

v6.0.0

Compare Source

===================

• Require Python 3.9 or later (breaking change).

• Remove MRUCache and the @func.mru_cache decorator (breaking
  change).

• Add an optional condition parameter to the @cached and
  @cachedmethod decorators, which, when used with a
  threading.Condition instance, should improve cache stampede <https://en.wikipedia.org/wiki/Cache_stampede>_ issues in massively
  parallel environments. Note that this will inflict some performance
  penalty, and therefore has to be enabled explicitly.

• Convert the cachetools.func decorators to use a
  threading.Condition instance to deal with cache stampede <https://en.wikipedia.org/wiki/Cache_stampede>_ issues. Note that
  this may result in a noticable performance degradation, depending
  on your actual use case.

• Deprecate support for cache(self) returning None to suppress
  caching with the @cachedmethod decorator.

• Improve documentation.

• Update CI environment.
