2022-08-05Invalidate lazyLoadCache if we're doing an initial sync (#2623)Till
* Bypass lazyLoadCache if we're doing an initial sync * Make the linter happy again? * Revert "Make the linter happy again?" This reverts commit 52a5691ba3c17c05698bcc6a13092090f27ace63. * Try that again * Invalidate LazyLoadCache on initial syncs * Remove unneeded check * Add TODO * Rename Invalite -> InvalidateLazyLoadedUser * Thanks IDE
2022-08-03Remove roominfo cache (#2615)Neil Alexander
* Remove roominfo cache It's the source of a number of race conditions which are seemingly causing bugs and CI failures. * Make the linter less sad
2022-07-19Add event state key cache (#2576)Neil Alexander
2022-07-18Tweak cache counters (#2575)Neil Alexander
* Tweak cache counters This makes the number of counters relative to the maximum cache size. Since the counters effectively manage the size of the bloom filter, larger caches need more counters and smaller caches need less. 10 counters per 1KB data means that the default cache size of 1GB should result in a bloom filter and TinyLRU admission set of about 16MB estimated. * Remove line left by accident

2022-05-17bugfix: E2EE device keys could sometimes not be sent to remote servers (#2466)kegsay
* Fix flakey sytest 'Local device key changes get to remote servers' * Debug logs * Remove internal/test and use /test only Remove a lot of ancient code too. * Use FederationRoomserverAPI in more places * Use more interfaces in federationapi; begin adding regression test * Linting * Add regression test * Unbreak tests * ALL THE LOGS * Fix a race condition which could cause events to not be sent to servers If a new room event which rewrites state arrives, we remove all joined hosts then re-calculate them. This wasn't done in a transaction so for a brief period we would have no joined hosts. During this interim, key change events which arrive would not be sent to destination servers. This would sporadically fail on sytest. * Unbreak new tests * Linting
