Compare Source

⚠️ Deprecations & removals:

• See changes to BSON and JSON serializers below:

💾 Serialization:

• Significantly reduce the memory usage of JSON serialization
• ⚠️ serializer='json' will no longer automatically use ultrajson if installed; it must be specified explicitly
• ⚠️ Drop support for standalone bson codec; please install pymongo to use BSON serialization
• Remove [bson] package extra to prevent accidentally installing it in the same environment as pymongo
• When using BSON serialization with the filesystem backend, add a .bson file extension by default
• Add support for orjson as a JSON serializer
  • However, see ijl/orjson#483 for potential memory issues
• Add the following serializer objects to specify a JSON library: json_serializer, ujson_serializer, and orjson_serializer
• Remove [json] package extra due to multiple supported JSON libraries
• Allow decode_content to be set to different values across multiple sessions in use at the same time

💾 Backends:

• SQLite:
  • Use exclusive transaction locks to prevent write contention; replaces retry behavior
• *Filesystem:
  • Add {py:class}requests_cache.backends.filesystem.LRUFileDict class to optionally limit the size of the filesystem cache. Enabled with max_cache_bytes argument.
• Redis:
  • For maintenance/inspection methods that iterate over the cache, use SCAN and HSCAN instead of KEYS, HKEYS, and HGETALL
• DynamoDB:
  • Add optional parameter create_table of DynamoDBCache to control if the class attempts to create the table in DynamoDB or not.
• GridFS:
  • Add a connection parameter to allow passing an existing MongoClient object

🕗 Expiration & headers:

• Add support for Vary: Cookie

⚙️ Session settings:

• Add autoclose option to close backend connections when the session is closed
• Add read_only option to read existing cached responses, but not write any new responses to the cache

• Add compatibility with FIPS-compliant systems
  • Note: Due to using a different hashing algorithm for cache keys, caches cannot be shared between FIPS- and non-FIPS-compliant systems
• Packaging and project config are now managed by uv
  • This has no impact for users; installation from PyPI still works the same
  • For developers, see Contributing Guide for details

🪲 Bugfixes:

• Fix request headers sent when expire_after is set to DO_NOT_CACHE
• Show a warning when initializing a cache with both cache_name and a backend instance (database names, file paths, etc. cannot be reliably updated after initialization)
• When updating response headers after revalidating a cached response, don't set both Content-Length and Transfer-Encoding
• Treat invalid HTTP dates (eg. 'Expires: 0' and 'Expires: -1') as 'already expired' as per RFC 2616, section 14.21

Compare Source

See all unreleased issues and PRs

🕗 Expiration & headers:

• Add support for Cache-Control: min-fresh
• Add support for Cache-Control: max-stale
• Add support for Cache-Control: only-if-cached
• Add support for Cache-Control: stale-if-error
• Add support for Cache-Control: stale-while-error

• Revalidate for Cache-Control: no-cache request or response header
• Revalidate for Cache-Control: max-age=0, must-revalidate response headers
• Add an attribute CachedResponse.revalidated to indicate if a cached response was revalidated for
  the current request

⚙️ Session settings:

• All settings that affect cache behavior can now be accessed and modified via CachedSession.settings
• Add always_revalidate session setting to always revalidate before using a cached response (if a validator is available).
• Add only_if_cached session setting to return only cached results without sending real requests
• Add stale_while_revalidate session setting to return a stale response initially, while a non-blocking request is sent to refresh the response
• Make behavior for stale_if_error partially consistent with Cache-Control: stale-if-error: Add support for time values (int, timedelta, etc.) in addition to True/False

⚙️ Request settings:

• Add only_if_cached option to CachedSession.request() and send() to return only cached results without sending real requests
• Add refresh option to CachedSession.request() and send() to revalidate with the server before using a cached response
• Add force_refresh option to CachedSession.request() and send() to awlays make and cache a new request regardless of existing cache contents
• Make behavior for expire_after=0 consistent with Cache-Control: max-age=0: if the response has a validator, save it to the cache but revalidate on use.
  • The constant requests_cache.DO_NOT_CACHE may be used to completely disable caching for a request

💾 Backends:

• DynamoDB:
  • For better read performance and usage of read throughput:
    • The cache key is now used as the partition key
    • Redirects are now cached only in-memory and not persisted
    • Cache size (len()) now uses a fast table estimate instead of a full scan
  • Store responses in plain (human-readable) document format instead of fully serialized binary
  • Create default table in on-demand mode instead of provisioned
  • Add optional integration with DynamoDB TTL to improve performance for removing expired responses
    • This is enabled by default, but may be disabled
  • Decode JSON and text response bodies so the saved response can be fully human-readable/editable.
    May be disabled with decode_content=False.
• Filesystem:
  • The default file format has been changed from pickle to JSON
  • Decode JSON and text response bodies so the saved response can be fully human-readable/editable.
    May be disabled with decode_content=False.
• MongoDB:
  • Store responses in plain (human-readable) document format instead of fully serialized binary
  • Add optional integration with MongoDB TTL to improve performance for removing expired responses
    • Disabled by default. See 'Backends: MongoDB' docs for details.
  • Decode JSON and text response bodies so the saved response can be fully human-readable/editable.
    May be disabled with decode_content=False.
• Redis:
  • Add ttl_offset argument to add a delay between cache expiration and deletion
• SQLite:
  • Improve performance for removing expired responses with delete()
  • Improve performance (slightly) with a large number of threads and high request rate
  • Add count() method to count responses, with option to exclude expired responses (performs a fast indexed count instead of slower in-memory filtering)
  • Add size() method to get estimated size of the database (including in-memory databases)
  • Add sorted() method with sorting and other query options
  • Add wal parameter to enable write-ahead logging
• SQLite, Redis, MongoDB, and GridFS:
  • Close open database connections when CachedSession is used as a contextmanager, or if CachedSession.close() is called

↔️ Request matching:

• Add serializer name to cache keys to avoid errors due to switching serializers
• Always skip both cache read and write for requests excluded by allowable_methods (previously only skipped write)
• Ignore and redact common authentication headers and request parameters by default. This provides
  some default recommended values for ignored_parameters, to avoid accidentally storing common
  credentials in the cache. This will have no effect if ignored_parameters is already set.
• Support distinct matching for requests that differ only by a parameter in ignored_parameters
  (e.g., for a request sent both with and without authentication)
• Support distinct matching for requests that differ only by duplicate request params (e.g, a=1 vs ?a=1&a=2)

ℹ️ Convenience methods:

• Add expired and invalid arguments to BaseCache.delete() (to replace remove_expired_responses())
• Add urls and requests arguments to BaseCache.delete() (to replace delete_url())
• Add older_than argument to BaseCache.delete() to delete responses older than a given value

• Add url argument to BaseCache.contains() method (to replace has_url())
• Add BaseCache.filter() method to get responses from the cache with various filters
• Add BaseCache.reset_expiration() method to reset expiration for existing responses
• Add BaseCache.recreate_keys() method to recreate cache keys for all previously cached responses
  (e.g., to preserve cache data after an update that changes request matching behavior)
• Update BaseCache.urls into a method that takes optional filter params, and returns sorted unique URLs

ℹ️ Response attributes and type hints:

• Add OriginalResponse type, which adds type hints to requests.Response objects for extra attributes added by requests-cache:
  • cache_key
  • created_at
  • expires
  • from_cache
  • is_expired
  • revalidated
• OriginalResponse.cache_key and expires will be populated for any new response that was written to the cache
• Add request wrapper methods with return type hints for all HTTP methods (CachedSession.get(), head(), etc.)
• Set CachedResponse.cache_key attribute for responses read from lower-level storage methods
  (items(), values(), etc.)

  • Previously, this would be quietly ignored, and the response would be cached indefinitely
• Fix behavior for stale_if_error if an error response code is added to allowable_codes

📦 Dependencies:

• Replace appdirs with platformdirs

⚠️ Deprecations:

The following methods are deprecated, and will be removed in 1.2. The recommended
replacements are listed below. If this causes problems for you, please open an issue to discuss.

• CachedSession.remove_expired_responses(): BaseCache.delete(expired=True)
• BaseCache.remove_expired_responses(): BaseCache.delete(expired=True)
• BaseCache.delete_url(): BaseCache.delete(urls=[...])
• BaseCache.delete_urls(): BaseCache.delete(urls=[...])
• BaseCache.has_key(): BaseCache.contains()
• BaseCache.has_url(): BaseCache.contains(url=...)
• BaseCache.keys(): BaseCache.responses.keys() (for all keys), or BaseCache.filter() (for filtering options)
• BaseCache.values(): BaseCache.responses.values() (for all values), or BaseCache.filter() (for filtering options)
• BaseCache.response_count(): len(BaseCache.responses) (for all responses), or BaseCache.filter() (for filtering options)

⚠️ Breaking changes:

• After initialization, cache settings can only be accessed and modified via CachedSession.settings. Previously, some settings could be modified by setting them on either CachedSession or BaseCache. In some cases this could silently fail or otherwise have undefined behavior.
• BaseCache.urls has been replaced with a method that returns a list of URLs.
• DynamoDB table structure has changed. If you are using the DynamoDB backend, you will need to create a new table when upgrading to 1.0. See DynamoDB backend docs for more details.

Minor breaking changes:

The following changes only affect advanced or undocumented usage, and are not expected to impact most users:

• The arguments match_headers and ignored_parameters must be passed to CachedSession. Previously, these could also be passed to a BaseCache instance.
• The CachedSession backend argument must be either an instance or string alias. Previously it would also accept a backend class.
• All serializer-specific BaseStorage subclasses have been removed, and merged into their respective parent classes. This includes SQLitePickleDict, MongoPickleDict, and GridFSPickleDict.
  • All BaseStorage subclasses now have a serializer attribute, which will be unused if set to None.
• The cache_control module (added in 0.7) has been split up into multiple modules in a new policy subpackage

v0.7.3

Compare Source

• SQLite backend:
  • Update DbCache.clear() to succeed even if the database is corrupted
  • Update DbDict.bulk_delete() to split the operation into multiple statements to support deleting more items than SQLite's variable limit (999)
• Filesystem backend:
  • When using JSON serializer, pretty-print JSON by default
  • Add an appropriate file extension to cache files (.json, .yaml, .pkl, etc.) by default; can be overridden or disabled with the extension parameter.
• Add a BaseCache.delete_urls() method to bulk delete multiple responses from the cache based on
  request URL

v0.7.2

Compare Source

• Add support for Response.next (to get the next request in a redirect chain) when 302 responses are cached directly
• Add a CachedResponse.cache_key attribute
• Make CachedResponse a non-slotted class to allow client code to set arbitrary attributes on it

v0.7.1

Compare Source

• Fix a bug in which Cache-Control headers would be used unexpectedly

v0.7.0

See all issues and PRs for 0.7

🕗 Expiration & headers:

• Add optional support for the following request headers:
  • Cache-Control: max-age
  • Cache-Control: no-cache
  • Cache-Control: no-store
• Add optional support for the following response headers:
  • Cache-Control: max-age
  • Cache-Control: no-store
  • Expires
• Add cache_control option to CachedSession to enable setting expiration with cache headers
• Add support for HTTP timestamps (RFC 5322) in expire_after parameters
• Add support for bypassing the cache if expire_after=0
• Add support for making a cache allowlist using URL patterns

💾 Backends:

• Add a filesystem backend that stores responses as local files
• DynamoDB:
  • Fix DynamoDbDict.__iter__ to return keys instead of values
  • Accept connection arguments for boto3.resource
• MongoDB:
  • Remove usage of deprecated pymongo Collection.find_and_modify()
  • Accept connection arguments for pymongo.MongoClient
• Redis:
  • Accept connection arguments for redis.Redis
• SQLite:
  • Use persistent thread-local connections, and improve performance for bulk operations
  • Add use_temp option to store files in a temp directory
  • Accept connection arguments for sqlite3.connect

💾 Serialization:

• Add data models for all serialized objects
• Add a JSON serializer
• Add a YAML serializer
• Add a BSON serializer
• Add optional support for cattrs
• Add optional support for ultrajson

↔️ Request matching:

• Add support for caching multipart form uploads
• Update ignored_parameters to also exclude ignored request params, body params, or headers from cached response data (to avoid storing API keys or other credentials)
• Update old_data_on_error option to also handle error response codes
• Only log request exceptions if old_data_on_error is set

ℹ️ Convenience methods:

• Add option to manually cache response objects with BaseCache.save_response()
• Add BaseCache.keys() and values() methods
• Add BaseCache.response_count() method to get an accurate count of responses (excluding invalid and expired)
• Show summarized response details with str(CachedResponse)
• Add more detailed repr methods for CachedSession, CachedResponse, and BaseCache
• Update BaseCache.urls to only skip invalid responses, not delete them (for better performance)

📦 Dependencies:

• Add minimum requests version of 2.17
• Add attrs as a dependency for improved serialization models
• Add cattrs as an optional dependency
• Add some package extras to install optional dependencies (via pip install):
  • requests-cache[all] (to install everything)
  • requests-cache[bson]
  • requests-cache[json]
  • requests-cache[dynamodb]
  • requests-cache[mongodb]
  • requests-cache[redis]

📦 Compatibility and packaging:

• requests-cache is now fully typed and PEP-561 compliant
• Fix some compatibility issues with requests 2.17 and 2.18
• Run pre-release tests for each supported version of requests
• Packaging is now managed by Poetry
  • For users, installation still works the same.
  • For developers, see Contributing Guide for details
