Changelog

Version 2.0.2

Released 2023-01-12

  • fix issue with boto3 dependencie due to latest cachelib released

  • migrate flask_caching.backends.RedisCluster dependency from redis-py-cluster to redis-py

  • bug fix: make the make_cache_key attributed of decorated view functions writeable. :pr:`431`, issue #97

Version 2.0.1

Released 2022-07-30

  • Relax dependency pin to allow Flask 2.x.x

Version 2.0.0

Released 2022-06-26

  • fix bug where flask_caching.backends.RedisSentinelCache.get_many would query wrong host&port combination. :pr:`372`

  • Remove flask_caching.backends.FileSystemCache method overrides. It now shares 100% of cachelib.FileSystemCache API and is fully compatible. Functionality relient on implementation details of said overrides from older releases might not work anymore. :pr:`369`

  • Add proxy to underlaying has method of cache clients. :pr:`356`

  • flask_caching.backends.FileSystemCache now stores timestamps in a universal (non-frammed) way following the lastest version of cachelib.FileSystemCache. The change also reduces overhead from 17 bytes (via previous method using pickle) to 4 bytes (using python’s struct). This, however, will break compatibily since older timestamps are serialized with a different strategy.

Version 1.10.0

Released 2021-03-04

  • Important: The way caching backends are loaded have been refactored. Instead of passing the name of the initialization function one can now use the full path to the caching backend class.

Released 2020-06-02

  • Add an option to include the functions source code when generating the cache key. :pr:`#156`

  • Add an feature that allows one to completely control the way how cache keys are generated. For example, one can now implement a function that generates a cache key the based on POST requests. :pr:`#159`

  • Fix the cache backend naming collisions by renaming them from simple to simplecache, null to nullcache and filesystem to filesystemcache.

  • Explicitly pass the default_timeout to RedisCache from RedisSentinelCache.

  • Use os.replace instead of werkzeug’s rename due to Windows raising an OSError if the dst file already exist.

  • Documentation updates and fixes.

Version 1.8.0

Released 2019-11-24

  • BREAKING: Removed support for Python 2. Python 3.5 and upwards are supported as of now.

Released 2019-05-28

This is the last version supporting Python 2!

  • Do not run a cached/memoized function if the cached return value is None. :pr:`#108`

Version 1.7.1

Released 2019-04-16

Released 2019-03-29

  • Added a feature called ‘response_filter’ which enables one to only cache views depending on the response code. :pr:`#99`

  • A DeprecationWarning got turned into a TypeError.

Version 1.6.0

Released 2019-03-06

  • The delete_many function is now able to ignore any errors and continue deleting the cache. However, in order to preserve backwards compatibility, the default mode is to abort the deletion process. In order to use the new deletion mode, one has to flip the config setting CACHE_IGNORE_ERRORS to True. This was and still is only relevant for the filesystem and simple cache backends. :pr:`#94`

  • Re-added the gaememcached CACHE_TYPE for improved backwards compatibility.

  • Documentation improvements

Version 1.3.0

Released 2017-06-17

  • Add uWSGI Caching backend (requires Werkzeug >= 0.12)

  • Provide a keyword query_string to the cached decorator in order to create the same cache key for different query string requests, so long as they have the same key/value (order does not matter). :pr:`#35`

  • Use pytest as test suite and test runner. Additionally, the tests have been split up into multiple files instead of having one big file.

Version 1.2.0

Version 1.1.0

Released 2016-12-09

Released 2016-08-30

  • The caching wrappers like add, set, etc are now returning the wrapped result as someone would expect. See #5

  • Changed the way of importing Flask-Cache. Instead of using the depreacted method for importing Flask Extensions (via flask.ext.cache), the name of the extension, flask_cache is used. Have a look at Flask’s documentation for more information regarding this matter. This also fixes the deprecation warning from Flask.

  • Lots of PEP8 and Documentation fixes.

  • Renamed this fork Flask-Caching (flask_caching) as it will now be available on PyPI for download.

  • #123 “forced_update” option to ‘cache’ and ‘memoize’ decorators

  • #124 Fix handling utf8 key args (cherry-picked)

  • #125 Fix unittest failing for redis unittest

  • #127 Improve doc for using @cached on view

  • Added better support for per-instance memoization.

  • Various bug fixes

Version 0.12

Released 2013-04-29

  • Changes jinja2 cache templates to use stable predictable keys. Previously the key for a cache tag included the line number of the template, which made it difficult to predict what the key would be outside of the application.

  • Adds config variable CACHE_NO_NULL_WARNING to silence warning messages when using ‘null’ cache as part of testing.

  • Adds passthrough to clear entire cache backend.

Version 0.11.1

Released 2013-04-7

  • Bugfix for using memoize on instance methods. The previous key was id(self), the new key is repr(self)

Version 0.11

Released 2013-03-23

  • Fail gracefully in production if cache backend raises an exception.

  • Support for redis DB number

  • Jinja2 templatetag cache now concats all args together into a single key instead of treating each arg as a separate key name.

  • Added delete memcache version hash function

  • Support for multiple cache objects on a single app again.

  • Added SpreadSASLMemcached, if a value is greater than the memcached threshold which defaults to 1MB, this splits the value across multiple keys.

  • Added support to use URL to connect to redis.

Version 0.10.1

Released 2013-01-13

  • Added warning message when using cache type of ‘null’

  • Changed imports to relative instead of absolute for AppEngine compatibility

Version 0.10.0

Released 2013-01-05

  • Added saslmemcached backend to support Memcached behind SASL authentication.

Version 0.8.0

Released 2012-09-30

  • Migrated to the new flask extension naming convention of flask_cache instead of flaskext.cache

  • Removed unnecessary dependencies in setup.py file.

  • Documentation updates

Version 0.7.0

Released 2012-08-25

  • Allows multiple cache objects to be instantiated with different configuration values.

Version 0.6.0

Released 2012-08-12

Version 0.5.0

Released 2012-02-03

  • Deleting memoized functions now properly functions in production environments where multiple instances of the application are running.

  • get_memoized_names and get_memoized_keys have been removed.

  • Added make_name to memoize, make_name is an optional callable that can be passed to memoize to modify the cache_key that gets generated.

  • Added unless to memoize, this is the same as the unless parameter in cached

  • memoization now converts all kwargs to positional arguments, this is so that when a function is called multiple ways, it would evaluate to the same cache_key

Version 0.4.0

Released 2011-12-11

  • Added attributes for uncached, make_cache_key, cache_timeout to the decorated functions.

Version 0.3.4

Released 2011-09-10

  • UTF-8 encoding of cache key

  • key_prefix argument of the cached decorator now supports callables.

Adds support for deleting memoized caches optionally based on function parameters.

Python 2.5 compatibility, plus bugfix with string.format.

Added the ability to retrieve memoized function names or cache keys.

Version 0.3.2

Bugfix release. Fixes a bug that would cause an exception if no CACHE_TYPE was supplied.

  • Added delete_memoized

Version 0.1

  • Initial public release
