* Combine Limiter and LinearizerRichard van der Hoff2018-07-201-89/+10
| | | | | Linearizer was effectively a Limiter with max_count=1, so rather than maintaining two sets of code, let's combine them.
* Improvements to the LimiterRichard van der Hoff2018-07-201-13/+20
| | | | | * give them names, to improve logging * use a deque rather than a list for efficiency
* Add a sleep to the Limiter to fix stack overflows.Richard van der Hoff2018-07-201-3/+20

| | * Use run_in_background in preference to preserve_fnRichard van der Hoff2018-04-271-2/+2
| | | | | | | | | | | | | | | | | | 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.

* / Backport deferred.addTimeoutRichard van der Hoff2018-04-271-0/+67
|/ | | | Twisted 16.0 doesn't have addTimeout, so let's backport it.
* Remove preserve_context_over_{fn, deferred}Richard van der Hoff2017-11-141-3/+3
| | | | | Both of these functions ae known to leak logcontexts. Replace the remaining calls to them and kill them off.
* Logging and logcontext fixes for LimiterRichard van der Hoff2017-11-071-7/+17
| | | | | | | | | 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.
* replace 'except:' with 'except Exception:'Richard van der Hoff2017-10-231-3/+3

* Fix logcontext handling for persist_eventsRichard van der Hoff2017-10-171-0/+5
| | | | | | | | * don't use preserve_context_over_deferred, which is known broken. * remove a redundant preserve_fn. * add/improve some comments
* Fix stackoverflow and logcontexts from linearizerRichard van der Hoff2017-10-111-2/+22
| | | | | | | 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.
* Fix logcontext handling for concurrently_executeRichard van der Hoff2017-10-061-2/+2
| | | | Avoid preserve_context_over_deferred, which is broken.
