Updates uvicorn from 0.51.0 to 0.52.1

Release notes

Sourced from uvicorn's releases.

Version 0.52.1

Fixed

• Complete the closing handshake on server-initiated WebSocket closes in the websockets-sansio and wsproto implementations, waiting for the client's close reply with a 10 second timeout instead of resetting the connection (#3053)
• Add missing write flow control to the websockets-sansio implementation, preventing data truncation on server-initiated closes with large in-flight payloads (#3048)
• Handle connection loss while a WebSocket write is waiting on backpressure (#3050)
• Remove duplicate Content-Type and Content-Length headers from WebSocket denial responses on the websockets-sansio implementation, and deliver non-UTF-8 denial bodies intact (#3041)

Full Changelog: Kludex/uvicorn@0.52.0...0.52.1

Version 0.52.0

This release adds an experimental HTTP/1.1 implementation backed by zttp, a sans-IO HTTP parser I've been developing on the side: a core written in Zig, with bindings to Python. It has been running under a fuzzer for some weeks now, and has been through multiple rounds of security auditing.

It is still experimental, so don't put it in front of production traffic yet. Try it with --http zttp, and please send any feedback to the issue tracker.

Added

• Add an experimental zttp HTTP/1.1 implementation, selectable with --http zttp (#2979)

Fixed

• Keep non-ASCII WebSocket request headers intact with websockets 17.0, which encodes them with ISO-8859-1 (#3036)
