Erik Johnston	9407bcf37a	Replace custom DeferredTimeoutError with defer.TimeoutError	6 years ago
Erik Johnston	6c48aa0256	Run canceller first to allow it to generate correct error	6 years ago
Erik Johnston	a334e1cace	Update to use new timeout function everywhere. ... The existing deferred timeout helper function (and the one into twisted) suffer from a bug when a deferred's canceller throws an exception, #3842. The new helper function doesn't suffer from this problem.	6 years ago
Erik Johnston	24efb2a70d	Fix timeout function ... Turns out deferred.cancel sometimes throws, so we do that last to ensure that we always do resolve the new deferred.	6 years ago
Erik Johnston	fcfe7a850d	Add an awful secondary timeout to fix wedged requests ... This is an attempt to mitigate #3842 by adding yet-another-timeout	6 years ago
Amber Brown	b37c472419	Rename async to async_helpers because `async` is a keyword on Python 3.7 (#3678)	6 years ago
Richard van der Hoff	638d35ef08	Fix linearizer cancellation on twisted < 18.7 ... Turns out that cancellation of inlineDeferreds didn't really work properly until Twisted 18.7. This commit refactors Linearizer.queue to avoid inlineCallbacks.	6 years ago
Richard van der Hoff	3d6df84658	Test and fix support for cancellation in Linearizer	6 years ago
Richard van der Hoff	7c712f95bb	Combine Limiter and Linearizer ... Linearizer was effectively a Limiter with max_count=1, so rather than maintaining two sets of code, let's combine them.	6 years ago
Richard van der Hoff	8462c26485	Improvements to the Limiter ... * give them names, to improve logging * use a deque rather than a list for efficiency	6 years ago

Richard van der Hoff	2a13af23bc	Use run_in_background in preference to preserve_fn ... While I was going through uses of preserve_fn for other PRs, I converted places which only use the wrapped function once to use run_in_background, to avoid creating the function object.	7 years ago
Richard van der Hoff	9d2c1b8429	Backport deferred.addTimeout ... Twisted 16.0 doesn't have addTimeout, so let's backport it.	7 years ago
Richard van der Hoff	7e6fa29cb5	Remove preserve_context_over_{fn, deferred} ... Both of these functions ae known to leak logcontexts. Replace the remaining calls to them and kill them off.	7 years ago
Richard van der Hoff	bf993db11c	Logging and logcontext fixes for Limiter ... Add some logging to the Limiter in a similar spirit to the Linearizer, to help debug issues. Also fix a logcontext leak. Also refactor slightly to avoid throwing exceptions.	7 years ago
Richard van der Hoff	eaaabc6c4f	replace 'except:' with 'except Exception:' ... what could possibly go wrong	7 years ago
Richard van der Hoff	2e9f5ea31a	Fix logcontext handling for persist_events ... * don't use preserve_context_over_deferred, which is known broken. * remove a redundant preserve_fn. * add/improve some comments	7 years ago
Richard van der Hoff	4fad8efbfb	Fix stackoverflow and logcontexts from linearizer ... 1. make it not blow out the stack when there are more than 50 things waiting for a lock. Fixes https://github.com/matrix-org/synapse/issues/2505. 2. Make it not mess up the log contexts.	7 years ago
