IPC-Manager-0.000024

Changes for version 0.000024 - 2026-04-18

  • Fix sync_request hang when a peer disappears mid-request: await_response now snapshots the peer at send time and croaks if the peer is fully removed from the bus before the response arrives. Suspend-capable protocols (those advertising suspend_supported) keep waiting across a clean suspend or a restart-under-a-new-pid because the response can still be delivered once the peer resumes — only full unregistration counts as "gone"
  • Add optional $timeout argument to sync_request() and await_response(); without it the behavior is unchanged (blocks indefinitely), with it the call croaks once the deadline elapses
  • Sweep orphaned Atomic::Pipe reassembly state when a peer leaves the bus: a new Client peer_left() hook (called from the service loop on peer-delta removal) lets AtomicPipe drop per-(pid, tid) parts/buffers entries belonging to dead peers instead of accumulating them forever
