Granian 2.8.0

on GitHub

What's Changed

New features

• Add header atom to access log format (#829 by @nitrag)

Changes

• BREAKING prioritize request's scope over OS env when building WSGI environ dict (#879 by @Barsoomx)
  • This means conflicting keys won't override WSGI request data anymore
• BREAKING TCP handshake errors are now logged under debug severity
• Add Python 3.15 support
• Drop free-threaded Python 3.13 support
• Bump PyO3 to 0.29 (#820 by @tobiasge)
• Bump dependencies

Enhancements

• BREAKING Refactor socket sharing on Linux
  • Granian on Linux now requires kernel >= 5.14 and net.ipv4.tcp_migrate_req sysctl option enabled when using multiple workers and respawn features
• BREAKING Implement (non-configurable) backpressure over streamed/iterable responses in ASGI and WSGI protocols
  • This trades a bit of throughput (mostly unnoticeable) for lower memory usage
• Refactor workers main loop and shutdown process

Fixes

• Fix several bugs on shutdown process (thanks @Malkiz223)
• Fix a shared socket bug on free-threaded Python causing crashes on workers respawn
