  fix(runner): fix audio task infinite loop and semaphore race

  kamil released this 2026-03-25 15:09:52 +05:00 | -247 commits to main since this release

  Two bugs caused audio tasks to loop endlessly:

  1. claimRecord never set heartbeat_at — newly claimed tasks had
     heartbeat_at=null, which matched the reaper's stale filter
     (heartbeat_at=null || heartbeat_at<threshold). Tasks were reaped
     and reset to pending within seconds of being claimed, before the
     30s heartbeat goroutine had a chance to write a timestamp.
     Fix: set heartbeat_at=now() in claimRecord alongside status=running.

  2. Audio semaphore was checked AFTER claiming the task. When the
     semaphore was full the select/break only broke the inner select,
     not the for loop — the code fell through and launched an uncapped
     goroutine that blocked forever on <-audioSem drain. The task also
     stayed status=running with no heartbeat, feeding bug #1.
     Fix: pre-acquire a semaphore slot BEFORE claiming the task; release
     it immediately if the queue is empty or claim fails.
