Bump gunicorn from 23.0.0 to 24.1.1

[dependabot]

Bumps gunicorn from 23.0.0 to 24.1.1.

Release notes

Sourced from gunicorn's releases.

24.1.1

Bug Fixes

• Fix forwarded_allow_ips and proxy_allow_ips to remain as strings for backward compatibility with external tools like uvicorn. Network validation now uses strict mode to detect invalid CIDR notation (e.g., 192.168.1.1/24 where host bits are set) (#3458, [PR #3459](benoitc/gunicorn#3459))

Full Changelog: benoitc/gunicorn@24.1.0...24.1.1

Gunicorn 24.1.0

New Features

• Official Docker Image: Gunicorn now publishes official Docker images to GitHub Container Registry ([PR #3454](benoitc/gunicorn#3454))

  • Available at ghcr.io/benoitc/gunicorn
  • Based on Python 3.12 slim image
  • Uses recommended worker formula (2 × CPU + 1)
  • Configurable via environment variables

• PROXY Protocol v2 Support: Extended PROXY protocol implementation to support the binary v2 format in addition to the existing text-based v1 format ([PR #3451](benoitc/gunicorn#3451))

  • New --proxy-protocol modes: off, v1, v2, auto
  • auto mode (default when enabled) detects v1 or v2 automatically
  • v2 binary format is more efficient and supports additional metadata
  • Works with HAProxy, AWS NLB/ALB, and other PROXY protocol v2 sources

• CIDR Network Support: --forwarded-allow-ips and --proxy-allow-from now accept CIDR notation (e.g., 192.168.0.0/16) for specifying trusted networks ([PR #3449](benoitc/gunicorn#3449))

• Socket Backlog Metric: New gunicorn.socket.backlog gauge metric reports the current socket backlog size on Linux systems ([PR #3450](benoitc/gunicorn#3450))

• InotifyReloader Enhancement: The inotify-based reloader now watches newly imported modules, not just those loaded at startup ([PR #3447](benoitc/gunicorn#3447))

Bug Fixes

• Fix signal handling regression where SIGCLD alias caused "Unhandled signal: cld" errors on Linux when workers fail during boot (#3453)
• Fix socket blocking mode on keepalive connections preventing SSL handshake failures with async workers ([PR #3452](benoitc/gunicorn#3452))
• Use smaller buffer size in finish_body() for faster timeout detection on slow or abandoned connections ([PR #3453](benoitc/gunicorn#3453))
• Handle SSLWantReadError in finish_body() to prevent worker hangs during SSL renegotiation ([PR #3448](benoitc/gunicorn#3448))
• Log SIGTERM as info level instead of warning to reduce noise in orchestrated environments ([PR #3446](benoitc/gunicorn#3446))
• Print exception details to stderr when worker fails to boot ([PR #3443](benoitc/gunicorn#3443))
• Fix unreader.unread() to prepend data to buffer instead of appending ([PR #3442](benoitc/gunicorn#3442))
• Prevent RecursionError when pickling Config objects ([PR #3441](benoitc/gunicorn#3441))
• Use proper exception chaining with raise from in glogging.py ([PR #3440](benoitc/gunicorn#3440))
