Summary

This release introduces several bug fixes and minor improvements across various modules including checks, mux_quic, servers, and acme. It also includes optimizations and new features for Lua integration and task management.

Migration Steps

  1. Remove the per-thread group wait queue.
  2. Remove wq_lock and the per-thread group wait queues.
  3. Move the lua httpclient code to http_client.c.
  4. Make __tasklet_wakeup_on() only accept non-local threads.
  5. Do not try to redistribute the WQ when single-threaded.

✨ New Features

  • Support healtcheck keyword on default-server lines.
  • Introduce acme_challenge_ready() for reuse outside the CLI.
  • Extend trace verbosity for H3.
  • Trace HTTP headers on FE side.
  • Trace HTTP headers on BE side.
  • Add REGISTER_HLUA_STATE_INIT() to register state init callbacks.
  • Implement ACME.challenge_ready() Lua function.
  • Add ha_diag_notice() to report diag-level notifications.
  • Publish ACME_NEWCERT event via event_hdl.
  • Publish ACME_DEPLOY event via event_hdl.
  • Add a dns-01 handler for Gandi LiveDNS API in lua/acme examples.
  • Introduce __task_set_state_and_tid.
  • Add __task_get_new_tid_field().
  • Introduce __task_get_current_owner.
  • Use __task_get_current_owner() in task_kill.
  • Start using __task_set_state_and_tid().
  • Use __task_set_state_and_tid() in task_instant_wakeup().
  • Allow multiple requests from a single core.httpclient() instance.
  • Add a BUG_ON on shut flags when the endpoint is shut.
  • Add missing NULL check after hpack_dht_defrag().
  • Make a copy of the sample expr in (set/add)-headers-bin.
  • Add a new explicitly local tasklet wakeup function.
  • Make tasklet_wakeup() explicitly call _tasklet_wakeup_here().
  • Make task_instant_wakeup() explicitly call _tasklet_wakeup_here().
  • Add a new flag TASK_RT to permit a task to skip the priority queue.
  • Add "rt=1" to "debug dev task" to tune the RT flag.
  • Add a new tasklet class for real-time: TL_RT.
