Original Pull Request: https://github.com/ArchiveBox/ArchiveBox/pull/1400

State: closed
Merged: No

Bumps urllib3 from 2.1.0 to 2.2.1.

Release notes

Sourced from urllib3's releases.

2.2.1

🚀 urllib3 is fundraising for HTTP/2 support

urllib3 is raising ~$40,000 USD to release HTTP/2 support and ensure long-term sustainable maintenance of the project after a sharp decline in financial support for 2023. If your company or organization uses Python and would benefit from HTTP/2 support in Requests, pip, cloud SDKs, and thousands of other projects please consider contributing financially to ensure HTTP/2 support is developed sustainably and maintained for the long-haul.

Thank you for your support.

Changes

Fixed issue where InsecureRequestWarning was emitted for HTTPS connections when using Emscripten. (#3331)

Fixed HTTPConnectionPool.urlopen to stop automatically casting non-proxy headers to HTTPHeaderDict. This change was premature as it did not apply to proxy headers and HTTPHeaderDict does not handle byte header values correctly yet. (#3343)

Changed ProtocolError to InvalidChunkLength when response terminates before the chunk length is sent. (#2860)

Changed ProtocolError to be more verbose on incomplete reads with excess content. (#3261)

2.2.0

🖥️ urllib3 now works in the browser

🎉 This release adds experimental support for using urllib3 in the browser with Pyodide! 🎉

Thanks to Joe Marshall (@joemarshall) for contributing this feature. This change was possible thanks to work done in urllib3 v2.0 to detach our API from http.client. Please report all bugs to the urllib3 issue tracker.

Changes

Added support for Emscripten and Pyodide, including streaming support in cross-origin isolated browser environments where threading is enabled. (#2951)

Added support for HTTPResponse.read1() method. (#3186)

Added rudimentary support for HTTP/2. (#3284)

Fixed issue where requests against urls with trailing dots were failing due to SSL errors when using proxy. (#2244)

Fixed HTTPConnection.proxy_is_verified and HTTPSConnection.proxy_is_verified to be always set to a boolean after connecting to a proxy. It could be None in some cases previously. (#3130)

Fixed an issue where headers passed in a request with json= would be mutated (#3203)

Fixed HTTPSConnection.is_verified to be set to False when connecting from a HTTPS proxy to an HTTP target. It was set to True previously. (#3267)

Fixed handling of new error message from OpenSSL 3.2.0 when configuring an HTTP proxy as HTTPS (#3268)

Fixed TLS 1.3 post-handshake auth when the server certificate validation is disabled (#3325)

Note for downstream distributors: To run integration tests, you now need to run the tests a second time with the --integration pytest flag. (#3181)
