* Fix some instances of ExpiringCache not expiring cache itemsErik Johnston2018-09-211-1/+0
| | | | | | | | 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.
* Make sure that we close db connections opened during initRichard van der Hoff2018-08-281-4/+1
| | | | | | | | | We should explicitly close any db connections we open, because failing to do so can block other transactions as per https://github.com/matrix-org/synapse/issues/3682. Let's also try to factor out some of the boilerplate by having server classes define their datastore class rather than duplicating the whole of `setup`.

| * Logcontexts for replication command handlersRichard van der Hoff2018-08-171-1/+2
| | | | | | | | | | | | | | | | | | | | Run the handlers for replication commands as background processes. This should improve the visibility in our metrics, and reduce the number of "running db transaction from sentinel context" warnings. Ideally it means converting the things that fire off deferreds into the night into things that actually return a Deferred when they are done. I've made a bit of a stab at this, but it will probably be leaky.
* | Fix logcontexts for running pushersRichard van der Hoff2018-08-171-2/+2
|/ | | | | | | First of all, avoid resetting the logcontext before running the pushers, to fix the "Starting db txn 'get_all_updated_receipts' from sentinel context" warning. Instead, give them their own "background process" logcontexts.

* Set Server header in SynapseRequestRichard van der Hoff2018-05-101-0/+1
| | | | | | | | | | | | (instead of everywhere that writes a response. Or rather, the subset of places which write responses where we haven't forgotten it). This also means that we don't have to have the mysterious version_string attribute in anything with a request handler. Unfortunately it does mean that we have to pass the version string wherever we instantiate a SynapseSite, which has been c&ped 150 times, but that is code that ought to be cleaned up anyway really.

| * Improve exception handling for background processesRichard van der Hoff2018-04-271-14/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There were a bunch of places where we fire off a process to happen in the background, but don't have any exception handling on it - instead relying on the unhandled error being logged when the relevent deferred gets garbage-collected. This is unsatisfactory for a number of reasons: - logging on garbage collection is best-effort and may happen some time after the error, if at all - it can be hard to figure out where the error actually happened. - it is logged as a scary CRITICAL error which (a) I always forget to grep for and (b) it's not really CRITICAL if a background process we don't care about fails. So this is an attempt to add exception handling to everything we fire off into the background.
* | 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.

* Factor out get_db_conn to HomeServer base classRichard van der Hoff2018-01-261-13/+0
| | | | | This function is identical to all subclasses, so we may as well push it up to the base class to reduce duplication (and make use of it in the tests)

* Reduce DB hits for replicationErik Johnston2016-09-231-2/+2
| | | | | | | | | | | | | | Some streams will occaisonally advance their positions without actually having any new rows to send over federation. Currently this means that the token will not advance on the workers, leading to them repeatedly sending a slightly out of date token. This in turns requires the master to hit the DB to check if there are any new rows, rather than hitting the no op logic where we check if the given token matches the current token. This commit changes the API to always return an entry if the position for a stream has changed, allowing workers to advance their tokens correctly.
