"""Tests for SessionStore._prune_stale_sessions_locked — crash self-healing.
|
|
|
|
When a gateway crashes (exit code 1) the graceful shutdown path is skipped and
|
|
sessions.json is left pointing at sessions already ended in state.db. On the
|
|
next startup _ensure_loaded_locked calls _prune_stale_sessions_locked to detect
|
|
and remove those stale routing entries before get_or_create_session() can reuse
|
|
them and silently route incoming messages into a closed session (#52804).
