* Fix stackoverflow and logcontexts from linearizerRichard van der Hoff2017-10-111-4/+24
| | | | | | | 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.
* Make get_state_groups_from_groups faster.Erik Johnston2017-05-171-1/+1
| | | | | | | | | Most of the time was spent copying a dict to filter out sentinel values that indicated that keys did not exist in the dict. The sentinel values were added to ensure that we cached the non-existence of keys. By updating DictionaryCache to keep track of which keys were known to not exist itself we can remove a dictionary copy.

* Fix the logcontext handling in the cache wrappers (#2077)Richard van der Hoff2017-03-301-0/+91
| | | | | | | The cache wrappers had a habit of leaking the logcontext into the reactor while the lookup function was running, and then not restoring it correctly when the lookup function had completed. It's all the fault of `preserve_context_over_{fn,deferred}` which are basically a bit broken.

| * Fix time_bound_deferred to throw the right exceptionRichard van der Hoff2017-03-231-0/+33
| | | | | | | | | | | | Due to a failure to instantiate DeferredTimedOutError, time_bound_deferred would throw a CancelledError when the deferred timed out, which was rather confusing.
* | Fix caching of remote servers' signature keysRichard van der Hoff2017-03-222-0/+100
|/ | | | | | | | | The `@cached` decorator on `KeyStore._get_server_verify_key` was missing its `num_args` parameter, which meant that it was returning the wrong key for any server which had more than one recorded key. By way of a fix, change the default for `num_args` to be *all* arguments. To implement that, factor out a common base class for `CacheDescriptor` and `CacheListDescriptor`.
* Stop preserve_fn leaking context into the reactorRichard van der Hoff2017-03-181-0/+61
| | | | | | | | Fix a bug in ``logcontext.preserve_fn`` which made it leak context into the reactor, and add a test for it. Also, get rid of ``logcontext.reset_context_after_deferred``, which tried to do the same thing but had its own, different, set of bugs.

* Speed up cache size calculationErik Johnston2017-01-171-15/+15
| | | | | | | | | | | 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.
