From e908b8683248328dd92479fc81be350336b9c8f4 Mon Sep 17 00:00:00 2001 From: Travis Ralston Date: Mon, 30 Jul 2018 16:24:02 -0600 Subject: Remove pdu_failures from transactions The field is never read from, and all the opportunities given to populate it are not utilized. It should be very safe to remove this. --- changelog.d/3628.misc | 1 + synapse/federation/federation_server.py | 4 --- synapse/federation/send_queue.py | 63 +-------------------------------- synapse/federation/transaction_queue.py | 32 +++-------------- synapse/federation/transport/server.py | 3 +- synapse/federation/units.py | 1 - tests/handlers/test_typing.py | 1 - 7 files changed, 8 insertions(+), 97 deletions(-) create mode 100644 changelog.d/3628.misc diff --git a/changelog.d/3628.misc b/changelog.d/3628.misc new file mode 100644 index 0000000000..1aebefbe18 --- /dev/null +++ b/changelog.d/3628.misc @@ -0,0 +1 @@ +Remove unused field "pdu_failures" from transactions. diff --git a/synapse/federation/federation_server.py b/synapse/federation/federation_server.py index e501251b6e..657935d1ac 100644 --- a/synapse/federation/federation_server.py +++ b/synapse/federation/federation_server.py @@ -207,10 +207,6 @@ class FederationServer(FederationBase): edu.content ) - pdu_failures = getattr(transaction, "pdu_failures", []) - for fail in pdu_failures: - logger.info("Got failure %r", fail) - response = { "pdus": pdu_results, } diff --git a/synapse/federation/send_queue.py b/synapse/federation/send_queue.py index 5157c3860d..0bb468385d 100644 --- a/synapse/federation/send_queue.py +++ b/synapse/federation/send_queue.py @@ -62,8 +62,6 @@ class FederationRemoteSendQueue(object): self.edus = SortedDict() # stream position -> Edu - self.failures = SortedDict() # stream position -> (destination, Failure) - self.device_messages = SortedDict() # stream position -> destination self.pos = 1 @@ -79,7 +77,7 @@ class FederationRemoteSendQueue(object): for queue_name in [ "presence_map", "presence_changed", "keyed_edu", "keyed_edu_changed", - "edus", "failures", "device_messages", "pos_time", + "edus", "device_messages", "pos_time", ]: register(queue_name, getattr(self, queue_name)) @@ -149,12 +147,6 @@ class FederationRemoteSendQueue(object): for key in keys[:i]: del self.edus[key] - # Delete things out of failure map - keys = self.failures.keys() - i = self.failures.bisect_left(position_to_delete) - for key in keys[:i]: - del self.failures[key] - # Delete things out of device map keys = self.device_messages.keys() i = self.device_messages.bisect_left(position_to_delete) @@ -204,13 +196,6 @@ class FederationRemoteSendQueue(object): self.notifier.on_new_replication_data() - def send_failure(self, failure, destination): - """As per TransactionQueue""" - pos = self._next_pos() - - self.failures[pos] = (destination, str(failure)) - self.notifier.on_new_replication_data() - def send_device_messages(self, destination): """As per TransactionQueue""" pos = self._next_pos() @@ -285,17 +270,6 @@ class FederationRemoteSendQueue(object): for (pos, edu) in edus: rows.append((pos, EduRow(edu))) - # Fetch changed failures - i = self.failures.bisect_right(from_token) - j = self.failures.bisect_right(to_token) + 1 - failures = self.failures.items()[i:j] - - for (pos, (destination, failure)) in failures: - rows.append((pos, FailureRow( - destination=destination, - failure=failure, - ))) - # Fetch changed device messages i = self.device_messages.bisect_right(from_token) j = self.device_messages.bisect_right(to_token) + 1 @@ -417,34 +391,6 @@ class EduRow(BaseFederationRow, namedtuple("EduRow", ( buff.edus.setdefault(self.edu.destination, []).append(self.edu) -class FailureRow(BaseFederationRow, namedtuple("FailureRow", ( - "destination", # str - "failure", -))): - """Streams failures to a remote server.
