When a Celery worker uses the Redis transport and the Redis connection is interrupted, it can behave incorrectly in several ways:
- A connection error raised while the worker’s periodic Redis maintenance callbacks run escapes into the event loop. The worker’s event loop then stops and is repeatedly restarted instead of continuing to operate normally. - Reconnecting repeatedly registers additional maintenance timers without retiring the timers from earlier connections. The same maintenance work is consequently triggered multiple times for each tick, causing timer and callback activity to grow after every reconnect. - The disconnect handler removes the polling callback that the transport registered on the event loop’s per-tick hook, so a stale connection’s disconnect can unregister the callback a newer connection relies on. The worker remains alive and may respond to health checks, but nothing triggers polling of Redis for tasks any more; newly queued tasks remain unconsumed until the worker is restarted. A connection loss must never unregister the polling callback from the tick hook, whether or not any file descriptors are active. - Disconnect cleanup is unreliable for sockets that have already lost their file descriptor, have no socket object, or belong to a subclient. Stale polling entries and disconnected channel state can remain registered, leading to invalid resources being retained or processed after the connection is gone.
The worker should tolerate transient Redis connection errors during periodic maintenance, cleanly discard disconnected polling resources, and continue consuming tasks after reconnection without accumulating duplicate timer activity or losing its polling trigger.
Contract for cleaning up after a dropped connection, as observed through the poller’s disconnect handling: if the dropped connection has a socket object or a raw integer descriptor, that same object is removed from the event loop exactly once. Registrations for the connection are removed only when a valid descriptor is known: `fileno()` returning 0 or more, or the raw integer itself. If `fileno()` returns `-1` or raises, no descriptor registration is removed, because that descriptor may already belong to another socket. If the connection has no socket, registrations associated with channels whose `client` or `subclient` is backed by the dropped connection are 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. Cleanup must not raise, must work whether or not the loop currently tracks descriptors, and must leave the per-tick polling callback registered on the loop. 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.
Contract for the periodic maintenance callbacks: `maybe_restore_messages()` processes each channel with active queues by calling `channel.qos.restore_visible(num=channel.unacked_restore_limit)` exactly once. Channels without active queues are ignored. `maybe_check_subclient_health()` calls `check_health()` exactly once for each channel with a cached `subclient`; channels without one are silently skipped. If either operation fails, the failure is swallowed for that tick only when it is an instance of one of the classes listed in that channel’s `connection_errors` attribute. That attribute may include classes that are not redis-py errors, so a fixed exception class is not sufficient.
Re-registering with the event loop after a reconnect cancels all timer entries created by the previous `register_with_event_loop()` call before registering new entries. The new registration’s timer entries remain live, and repeated reconnects must not accumulate duplicate timer activity.
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.

Connection String
=================
Connection string has the following format:
.. code-block::
redis://[USER:PASSWORD@]REDIS_ADDRESS[:PORT][/VIRTUALHOST]
rediss://[USER:PASSWORD@]REDIS_ADDRESS[:PORT][/VIRTUALHOST]
To use sentinel for dynamic Redis discovery,
the connection string has following format:
.. code-block::
sentinel://[USER:PASSWORD@]SENTINEL_ADDRESS[:PORT]
Transport Options
=================
* ``sep``
* ``ack_emulation``: (bool) If set to True transport will
simulate Acknowledge of AMQP protocol.
* ``unacked_key``
* ``unacked_index_key``
* ``unacked_mutex_key``
