Cleanup never matched a live session because the controller registered empty
manifest and segment paths, renewal was a read-modify-write that could revert a
takeover, and the takeover script compared an ISO date to a number, so it errored.
- populate the session record's manifest and segment paths from the playlist path
- renew the lease via a Lua compare-and-set on the owning pod
- store the lease expiry as unix milliseconds so the scripts can compare it
- retain the session record past its lease so an orphan can still be taken over
- test the Redis store against a real Redis, including the renew-vs-takeover race
- drop the live stream record nothing ever read back
Timer-driven library tasks fire on every replica, so a library refresh or a
database optimise runs once per pod against the same shared library.
- add IScanLeaderLease with a Redis TTL implementation and a no-op default
- skip timer-driven runs of the gated tasks on instances without the lease
- treat an unreachable Redis as holding the lease so tasks never stop running
- leave manual and API-triggered runs ungated
Every replica runs the transcode cleanup task against the same shared transcode
directory, so one pod deletes segments another pod is still streaming.
- read the active sessions from ITranscodeSessionStore before deleting
- keep files matching an active session manifest path or segment prefix
- abort the sweep when the store cannot be reached
