The prompt the agent sees
Two changes to celery's result backends.
A shared reconnection API on the base result consumer. `BaseResultConsumer` (celery/backends/asynchronous.py) must provide what the Redis and RPC consumers currently each implement privately: - A class attribute `_connection_errors`, an empty tuple by default, naming the transport exceptions that mean the connection was lost. - A context manager method `reconnect_on_error()`. A block that raises nothing completes normally. An exception that is not an instance of `_connection_errors` propagates unchanged, and with the default empty tuple every exception propagates, including one that would be a connection error for a real transport. When the block raises one of `_connection_errors`, the manager calls `self._reconnect()` with no arguments exactly once and suppresses the original error. If `_reconnect()` itself raises one of `_connection_errors`, the manager logs a critical message and raises `RuntimeError` whose message contains `Retry limit exceeded`, chained so that its `__cause__` is exactly the exception `_reconnect()` raised. The message constant is defined in this module and no longer in the Redis backend. - A method `_reconnect()` that the base class implements as a no-op returning `None`, for subclasses to override. The Redis consumer's own `reconnect_on_error` is replaced by overriding `_reconnect()` to re-establish its pub/sub connection through its existing retry helper. The RPC consumer drops its private `_handle_connection_errors` in favour of `reconnect_on_error()`, sets `_connection_errors` to its connection's `connection_errors + channel_errors` both when constructed and again after reconnecting, and logs the lost-connection warning from `_reconnect()`.
Extra connection-error types for the Redis result backend. `RedisBackend.__init__` must read `additional_connection_errors` from `app.conf.result_backend_transport_options` and append every valid entry to the backend's `connection_errors`, so that `backend.exception_safe_to_retry` accepts them and `backend.result_consumer._connection_errors` includes them too. The value may be: - a tuple or other iterable of entries, a single exception class, or a single dotted import path string such as `'t.unit.backends.test_redis.ConnectionError'`; - where each entry is either an exception class or a dotted path resolved with celery's `symbol_by_name`. An empty tuple, `None`, or a missing key adds nothing, so `ConnectionError` is then absent from `connection_errors`. Invalid entries are skipped with a warning and never stop the backend from being created: a path that fails to import such as `'no.such.module.Error'`, a class that is not an `Exception` subclass such as `int`, and a value that is not a class at all such as `42`. With `(ConnectionError, int)` the result contains `ConnectionError` and not `int`.

The current Redis consumer owns the retry context and the RPC consumer owns a separate error handler. I’ll move the common exception-handling semantics into `BaseResultConsumer`, preserve Redis’s existing retry helper in `_reconnect()`, and update RPC’s connection-error tuple whenever its Kombu connection changes. Redis option parsing will normalize scalar versus iterable values and validate imported/classes before extending the backend tuple.

Plan: add the context-managed reconnection contract and retry-limit constant/logging to `BaseResultConsumer`; make Redis delegate reconnection through `_reconnect`; update RPC to use the shared manager and refresh its error tuple around connection creation/reconnection; finally normalize and validate Redis transport-option exception entries before constructing the consumer. I’ll preserve existing reconnect behavior and ensure non-transport exceptions remain untouched.
