From d3347ad48553bd678fca7e3259d0824225cc6af2 Mon Sep 17 00:00:00 2001 From: Richard van der Hoff Date: Fri, 13 Apr 2018 11:16:43 +0100 Subject: [PATCH] Revert "Use sortedcontainers instead of blist" This reverts commit 9fbe70a7dc3afabfdac176ba1f4be32dd44602aa. It turns out that sortedcontainers.SortedDict is not an exact match for blist.sorteddict; in particular, `popitem()` removes things from the opposite end of the dict. This is trivial to fix, but I want to add some unit tests, and potentially some more thought about it, before we do so. --- synapse/federation/send_queue.py | 14 +++++++------- synapse/python_dependencies.py | 2 +- synapse/util/caches/stream_change_cache.py | 4 ++-- 3 files changed, 10 insertions(+), 10 deletions(-) diff --git a/synapse/federation/send_queue.py b/synapse/federation/send_queue.py index 945832283f..93e5acebc1 100644 --- a/synapse/federation/send_queue.py +++ b/synapse/federation/send_queue.py @@ -35,7 +35,7 @@ from synapse.storage.presence import UserPresenceState from synapse.util.metrics import Measure import synapse.metrics -from sortedcontainers import SortedDict +from blist import sorteddict from collections import namedtuple import logging @@ -56,19 +56,19 @@ class FederationRemoteSendQueue(object): self.is_mine_id = hs.is_mine_id self.presence_map = {} # Pending presence map user_id -> UserPresenceState - self.presence_changed = SortedDict() # Stream position -> user_id + self.presence_changed = sorteddict() # Stream position -> user_id self.keyed_edu = {} # (destination, key) -> EDU - self.keyed_edu_changed = SortedDict() # stream position -> (destination, key) + self.keyed_edu_changed = sorteddict() # stream position -> (destination, key) - self.edus = SortedDict() # stream position -> Edu + self.edus = sorteddict() # stream position -> Edu - self.failures = SortedDict() # stream position -> (destination, Failure) + self.failures = sorteddict() # stream position -> (destination, Failure) - self.device_messages = SortedDict() # stream position -> destination + self.device_messages = sorteddict() # stream position -> destination self.pos = 1 - self.pos_time = SortedDict() + self.pos_time = sorteddict() # EVERYTHING IS SAD.
