Thanks to Code Shelter and contributors for making this release possible!

Serialization

Note: Due to the following changes, responses cached with previous versions of requests-cache will be invalid. These old responses will be treated as expired, and will be refreshed the next time they are requested. They can also be manually converted or removed, if needed (see notes below).

  • Add example script to convert an existing cache from previous serialization format to new one

  • When running remove_expired_responses(), also remove responses that are invalid due to updated serialization format

  • Add CachedResponse class to wrap cached requests.Response objects, which makes additional cache information available to client code

  • Add CachedHTTPResponse class to wrap urllib3.response.HTTPResponse objects, available via CachedResponse.raw

    • Re-construct the raw response on demand to avoid storing extra data in the cache

    • Improve emulation of raw request behavior used for iteration, streaming requests, etc.

  • Add BaseCache.urls property to get all URLs persisted in the cache

  • Add optional support for itsdangerous for more secure serialization

Cache Expiration

  • Cached responses are now stored with an absolute expiration time, so CachedSession.expire_after no longer applies retroactively. To revalidate previously cached items with a new expiration time, see below:

  • Add support for overriding original expiration (i.e., revalidating) in CachedSession.remove_expired_responses()

  • Add support for setting expiration for individual requests

  • Add support for setting expiration based on URL glob patterns

  • Add support for setting expiration as a datetime

  • Add support for explicitly disabling expiration with -1 (Since None may be ambiguous in some cases)

Backends

  • SQLite: Allow passing user paths (~/path-to-cache) to database file with db_path param

  • SQLite: Add timeout parameter

  • Make default table names consistent across backends ('http_cache')

Bugfixes

  • Fix caching requests with data specified in json parameter

  • Fix caching requests with verify parameter

  • Fix duplicate cached responses due to some unhandled variations in URL format

    • To support this, the url-normalize library has been added to dependencies

  • Fix usage of backend-specific params when used in place of cache_name

  • Fix potential TypeError with DbPickleDict initialization

  • Fix usage of CachedSession.cache_disabled if used within another contextmanager

  • Fix non-thread-safe iteration in BaseCache

  • Fix get_cache(), clear(), and remove_expired_responses() so they will do nothing if requests-cache is not installed

  • Update usage of deprecated MongoClient save() method

  • Replace some old bugs with new and different bugs, just to keep life interesting
