Liquidsoap 2.4.5

2.4.5 (2026-06-15)

New:

• Added remove and remove_request_id methods to request.queue to remove
  a specific request from the queue, also available as a telnet remove command (#5237)
• Improved error messages in playlist parsers to include more context about the
  source of the error
• Added audio/aiff, audio/x-aiff and audio/x-wavpack entries to
  the default settings.http.mime.extnames table so protocol.http resolves
  AIFF and WavPack URLs to their real extensions instead of the .osb
  fallback.

Fixed:

• Fixed crash when external input (input.process, input.ffmpeg, etc.) encounters an EOF (thanks to @MikaSappi, #5139)
• Fixed harbor.remove_http_handler discarding all registered handlers except the one being removed
• Fixed crash in crossfade/cross when source.skip is called from outside the clock thread, e.g. from a harbor.http handler or thread.run (#5194)
• Fixed memory leak in Strings.Mutable (#5231)

Optimized:

• Clock sync-source propagation is now push-based and O(1) per tick instead of scanning all sources (#5133)
• Stream format/kind dispatch now uses O(1) int-indexed array lookup instead of iterating a queue (#5136)
• Optimized content_length and timed blit hot paths (#5137)
• Chunk total length is now cached in the chunks record to avoid recomputation (#5140)
• Chunk length is now pre-computed on lift (#5135)
• Watcher before/after cycle callbacks are only registered when watchers are actually present
• WeakQueue now uses geometric doubling and a RW-lock for faster concurrent access (#5118)
• Use direct Int comparison functions in stream hot paths
