* Fix ClientReplicationStreamProtocol.__str__ (#4929)Richard van der Hoff2019-03-252-4/+5
| | | | | | | | `__str__` depended on `self.addr`, which was absent from ClientReplicationStreamProtocol, so attempting to call str on such an object would raise an exception. We can calculate the peer addr from the transport, so there is no need for addr anyway.
* Fix bug where read-receipts lost their timestamps (#4927)Richard van der Hoff2019-03-252-11/+27
| | | | | Make sure that they are sent correctly over the replication stream. Fixes: #4898

| | | Setting this to 50 or so makes a bunch of sytests fail in worker mode.

| * Increase the max delay between retry attemptsErik Johnston2019-02-261-1/+1
| | | | | | | | | | Otherwise if you have many workers they can easily take out master with their connection attempts
| * Fix tightloop over connecting to replication serverErik Johnston2019-02-262-4/+39
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If the client failed to process incoming commands during the initial set up of the replication connection it would immediately disconnect and reconnect, resulting in a tightloop. This can happen, for example, when subscribing to a stream that has a row that is too long in the backlog. The fix here is to not consider the connection successfully set up until the client has succesfully subscribed and caught up with the streams. This ensures that the retry logic timers aren't reset until then, meaning that if an error does happen during start up the client will continue backing off before retrying again.

* Remove conn_id from repl prometheus metricsErik Johnston2018-09-031-10/+10
| | | | | `conn_id` gets set to a random string, and so we end up filling up prometheus with tonnes of data series, which is bad.
* Logcontexts for replication command handlersRichard van der Hoff2018-08-173-15/+43
| | | | | | | | | | 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 unit testsRichard van der Hoff2018-07-251-1/+1
| | | | | | on_notifier_poke no longer runs synchonously, so we have to do a different hack to make sure that the replication data has been sent. Let's actually listen for its arrival.
* Wrap a number of things that run in the backgroundRichard van der Hoff2018-07-251-6/+8
