Erik Johnston	2506074ef0	Fix receipts or account data not being sent down sync (#9193) ... Introduced in #9104 This wasn't picked up by the tests as this is all fine the first time you run Synapse (after upgrading), but then when you restart the wrong value is pulled from `stream_positions`.	4 years ago

Erik Johnston	8de3703d21	Make event persisters periodically announce position over replication. (#8499) ... Currently background proccesses stream the events stream use the "minimum persisted position" (i.e. `get_current_token()`) rather than the vector clock style tokens. This is broadly fine as it doesn't matter if the background processes lag a small amount. However, in extreme cases (i.e. SyTests) where we only write to one event persister the background processes will never make progress. This PR changes it so that the `MultiWriterIDGenerator` keeps the current position of a given instance as up to date as possible (i.e using the latest token it sees if its not in the process of persisting anything), and then periodically announces that over replication. This then allows the "minimum persisted position" to advance, albeit with a small lag.	4 years ago
Erik Johnston	e3debf9682	Add logging on startup/shutdown (#8448) ... This is so we can tell what is going on when things are taking a while to start up. The main change here is to ensure that transactions that are created during startup get correctly logged like normal transactions.	4 years ago
