Erik Johnston	8ea887856c	Don't update eviction metrics on explicit removal	6 years ago
Erik Johnston	3baf6e1667	Fix ExpiringCache.__len__ to be accurate ... It used to try and produce an estimate, which was sometimes negative. This caused metrics to be sad, so lets always just calculate it from scratch. (This appears to have been a longstanding bug, but one which has been made more of a problem by #3932 and #3933). (This was originally done by Erik as part of #3933. I'm cherry-picking it because really it's a fix in its own right)	7 years ago

Erik Johnston	fdd1a62e8d	Add a five minute cache to get_destination_retry_timings ... Hopefully helps with #3931	7 years ago
Erik Johnston	79eded1ae4	Make ExpiringCache slightly more performant	7 years ago
Erik Johnston	8601c24287	Fix some instances of ExpiringCache not expiring cache items ... ExpiringCache required that `start()` be called before it would actually start expiring entries. A number of places didn't do that. This PR removes `start` from ExpiringCache, and automatically starts backround reaping process on creation instead.	7 years ago
Richard van der Hoff	03751a6420	Fix some looping_call calls which were broken in #3604 ... It turns out that looping_call does check the deferred returned by its callback, and (at least in the case of client_ips), we were relying on this, and I broke it in #3604. Update run_as_background_process to return the deferred, and make sure we return it to clock.looping_call.	7 years ago
Richard van der Hoff	667fba68f3	Run things as background processes ... This fixes #3518, and ensures that we get useful logs and metrics for lots of things that happen in the background. (There are certainly more things that happen in the background; these are just the common ones I've found running a single-process synapse locally).	7 years ago

Richard van der Hoff	bc496df192	report metrics on number of cache evictions	7 years ago
Erik Johnston	c72058bcc6	Use an ExpiringCache for storing registration sessions ... This is because pruning them was a significant performance drain on matrix.org	8 years ago
Erik Johnston	3545e17f43	Add setdefault key to ExpiringCache	8 years ago
Erik Johnston	f85b6ca494	Speed up cache size calculation ... Instead of calculating the size of the cache repeatedly, which can take a long time now that it can use a callback, instead cache the size and update that on insertion and deletion. This requires changing the cache descriptors to have two caches, one for pending deferreds and the other for the actual values. There's no reason to evict from the pending deferreds as they won't take up any more memory.	8 years ago
Erik Johnston	6d00213e80	Use OrderedDict in ExpiringCache	8 years ago
Erik Johnston	46aebbbcbf	Add support for 'iterable' to ExpiringCache	8 years ago
Erik Johnston	73c7112433	Change CacheMetrics to be quicker ... We change it so that each cache has an individual CacheMetric, instead of having one global CacheMetric. This means that when a cache tries to increment a counter it does not need to go through so many indirections.	9 years ago
