The bug report the agent sees
Redis workers can stop consuming tasks after a broker connection is lost and re-established. If a stale connection reports its disconnect after the replacement connection has registered polling, the worker remains alive but no longer receives tasks; new messages accumulate in Redis instead of being consumed. Disconnect handling must clean up the disconnected socket and its event-loop file-descriptor mapping, including when the socket is represented by a raw descriptor or has no usable descriptor. It must also leave the polling callback registered on the event loop’s per-tick hook: a connection loss must never unregister that callback, whether or not any file descriptors are active, so that polling resumes as soon as the replacement connection is registered.
Separately, shutting down a channel can race with task completion. During restoration of unacknowledged messages, a message may be acknowledged by another thread after restoration begins but before that message is processed. In this case the broker can report that the message is missing or unavailable, and shutdown must not surface this expected race as an error. Already-acknowledged messages must not produce restoration errors, while genuine restoration failures must remain observable. This is a separate bug in the virtual transport base’s unacked-message restoration, which every virtual transport uses when a channel closes; it is not the Redis transport’s periodic restore described above. When restoring a message raises, the error must be recorded only if that message has not been acknowledged since the flush at the start of the restore. A message acknowledged in the meantime is dropped from the unacknowledged set without an error, while failures for messages that were never acknowledged are still returned to the caller.
Contract for cleaning up after a dropped connection, as observed through the poller’s disconnect handling: if the dropped connection still has a socket object or a raw integer descriptor, that same object must be removed from the event loop exactly once. Its entry must be removed from the poller’s descriptor-to-channel registrations only when a valid descriptor is known: `fileno()` values of 0 or greater and raw integer descriptors. If `fileno()` returns `-1` or raises, no registration is removed, because that descriptor may already belong to another socket. Missing registrations and other cleanup races must not raise. The poller object the transport is registered with may support nothing beyond its descriptor set, its descriptor-to-channel mapping and its callbacks: the transport's own disconnect handling must perform the loop removal and the pruning itself, must not read poller attributes that nothing has set, and must not rely on a disconnect method of the poller doing the work (it may be inert); any per-registration state such as timer handles has to be kept by the transport's own code.
If the connection has no socket at all, nothing is removed from the loop. Registrations associated with channels whose `client` or `subclient` is backed by the dropped connection must instead be removed, while registrations belonging to other connections remain. The channels expose `client` and `subclient` as ordinary attributes and may be lightweight objects without a populated instance dictionary. All of this holds whether or not the loop currently tracks any descriptors, and the per-tick polling callback remains registered on the loop.
How the tests reach the cleanup: they replace `transport.cycle` with a `Mock` (spec'd to `fds`, `_fd_to_chan`, `on_poll_init`, `on_poll_start`, `maybe_restore_messages`, `maybe_check_subclient_health` and `_on_connection_disconnect`) BEFORE calling `redis.Transport.register_with_event_loop(transport, conn, loop)`, then call `transport.cycle._on_connection_disconnect(connection)` and assert on `loop.remove`, `cycle._fd_to_chan` and `loop.on_tick`. So registering with the event loop must assign the disconnect cleanup callable to the poller's `_on_connection_disconnect` attribute, and that callable must act on the `loop` object that was passed to `register_with_event_loop`; cleanup logic that lives only as a method of the real poller class is never executed.
