Unreleased

  • Assume config file is located at config/pitchfork.rb if -c argument isn't provided.

0.16.0

  • Use exit! for exiting the middle process when forking a new worker or mold. This skips at_exit and finalizer hooks, which shouldn't be needed.

0.15.0

  • Encode pure ASCII strings in Rack env as UTF-8, as allowed by the rack spec. Other strings remain as ASCII-8BIT aka BINARY as required by the rack spec.
  • Fix compatibility with Rack 3.1.
  • Fix rack.hijack support.
  • Support Rack 3 streaming bodies.
  • Implement listen queues for fairer load balancing (optional).
  • Assume C99 compatible compiler.
  • Declare dependency on logger for Ruby 3.5 compatibility.

0.14.0

  • Remove the dependency on raindrops.
  • Add X-Request-Id header in the workers proctitle if present.
  • Added experimental service workers.

0.13.0

  • Fix compatibility with --enable-frozen-string-literal in preparation for Ruby 3.4.
  • Extend timed out workers deadline after sending signals to avoid flooding.
  • Fix compilation with Ruby 2.7 and older on macOS.

0.12.0

  • Disable IO tracking on Rubies older than 3.2.3 to avoid running into https://bugs.ruby-lang.org/issues/19531. This Ruby bug can lead to memory corruption that cause VM crashes when calling various IO methods.
  • Implement rack.response_finished (#97).
  • Don't break the rack.after_reply callback chain if one callback raises (#97).

0.11.1

  • Fix Ruby 3.4-dev compatibility.

0.11.0

  • Drop invalid response headers.
  • Enforce spawn_timeout for molds too.
  • Gracefully shutdown the server if the mold appear to be corrupted (#79).
  • Add more information in proctitle when forking a new sibbling.
  • Add a before_fork callback called before forking new molds and new workers.

0.10.0

  • Include requests count in workers proctitle.

0.9.0

  • Implement spawn_timeout to protect against bugs causing workers to get stuck before they reach ready state.

0.8.0

  • Add an after_monitor_ready callback, called in the monitor process at end of boot.
  • Implement Pitchfork.prevent_fork for use in background threads that synchronize native locks with the GVL released.

0.7.0

  • Set nicer proctile to better see the state of the process tree at a glance.
  • Pass the last request env to after_request_complete callback.
  • Fix the slow rollout of workers on a new generation.
  • Expose Pitchfork::Info.fork_safe? and Pitchfork::Info.no_longer_fork_safe!.

0.6.0

  • Expose Pitchfork::Info.workers_count and .live_workers_count to be consumed by application health checks.
  • Implement before_worker_exit callback.
  • Make each mold and worker a process group leader.
  • Get rid of Pitchfork::PrereadInput.
  • Add Pitchfork.shutting_down? to allow health check endpoints to fail sooner on graceful shutdowns.
  • Treat TERM as graceful shutdown rather than quick shutdown.
  • Implement after_worker_hard_timeout callback.

0.5.0

  • Added a soft timeout in addition to the historical Unicorn hard timeout. On soft timeout, the after_worker_timeout callback is invoked.
  • Implement after_request_complete callback.

0.4.1

  • Avoid a Rack 3 deprecation warning.
  • Fix handling on non-ASCII cookies.
  • Log unknown process being reaped at INFO level.

0.4.0

  • Preserve the current thread when reforking.

0.3.0

  • Renamed after_promotion in after_mold_fork.
  • Renamed after_fork in after_worker_fork.
  • Backoff 10s after every mold spawning attempt.
  • Spawn mold from workers instead of promoting workers (#42).

0.2.0

  • Remove default middlewares.
  • Refork indefinitely when refork_after is set, unless the last element is false.
  • Remove mold_selector. The promotion logic has been moved inside workers (#38).
  • Add the after_promotion callback.
  • Removed the before_fork callback.
  • Fork workers and molds with a clean stack to allow more generations. (#30)

0.1.2

  • Improve Ruby 3.2 and Rack 3 compatibility.

0.1.1

  • Fix extconf.rb to move the extension in the right place on gem install. (#18)

0.1.0
