* Fix (final) Bugbear violations (#9838)Jonathan de Jong2021-04-201-2/+2

* Remove redundant "coding: utf-8" lines (#9786)Jonathan de Jong2021-04-149-9/+0
| | | | | | | Part of #9744 Removes all redundant `# -*- coding: utf-8 -*-` lines from files, as python 3 automatically reads source code as utf-8 now. `Signed-off-by: Jonathan de Jong <jonathan@automatia.nl>`
* Use mock from the stdlib. (#9772)Patrick Cloke2021-04-092-2/+2

* Make it possible to use dmypy (#9692)Erik Johnston2021-03-261-0/+1
| | | | | | | | | Running `dmypy run` will do a `mypy` check while spinning up a daemon that makes rerunning `dmypy run` a lot faster. `dmypy` doesn't support `follow_imports = silent` and has `local_partial_types` enabled, so this PR enables those options and fixes the issues that were newly raised. Note that `local_partial_types` will be enabled by default in upcoming mypy releases.
* Clean up `ShardedWorkerHandlingConfig` (#9466)Erik Johnston2021-02-241-1/+1
| | | | | | | | | | | | | | | | | * Split ShardedWorkerHandlingConfig This is so that we have a type level understanding of when it is safe to call `get_instance(..)` (as opposed to `should_handle(..)`). * Remove special cases in ShardedWorkerHandlingConfig. `ShardedWorkerHandlingConfig` tried to handle the various different ways it was possible to configure federation senders and pushers. This led to special cases that weren't hit during testing. To fix this the handling of the different cases is moved from there and `generic_worker` into the worker config class. This allows us to have the logic in one place and allows the rest of the code to ignore the different cases.
* Update black, and run auto formatting over the codebase (#9381)Eric Eastwood2021-02-163-10/+12
| | | | | | | - Update black version to the latest - Run black auto formatting over the codebase - Run autoformatting according to [`docs/code_style.md `](https://github.com/matrix-org/synapse/blob/80d6dc9783aa80886a133756028984dbf8920168/docs/code_style.md) - Update `code_style.md` docs around installing black to use the correct version
* Tell Black to format code for Python 3.5 (#8664)Dan Callahan2020-10-271-1/+1
| | | | | | | | This allows trailing commas in multi-line arg lists. Minor, but we might as well keep our formatting current with regard to our minimum supported Python version. Signed-off-by: Dan Callahan <danc@element.io>
* Convert the message handler to async/await. (#7884)Patrick Cloke2020-07-221-32/+44
|
* Discard RDATA from already seen positions. (#7648)Patrick Cloke2020-06-152-21/+141
|
* fix mypy for tests/replication (#7518)Richard van der Hoff2020-05-181-2/+2
|
* Fix limit logic for AccountDataStream (#7384)Richard van der Hoff2020-05-151-0/+117
| | | | | | Make sure that the AccountDataStream presents complete updates, in the right order. This is much the same fix as #7337 and #7358, but applied to a different stream.
* Clean up replication unit tests. (#7490)Erik Johnston2020-05-135-311/+4
|
* Fix catchup-on-reconnect for the Federation Stream (#7374)Richard van der Hoff2020-05-053-12/+94
| | | | looks like we managed to break this during the refactorathon.
* Thread through instance name to replication client. (#7369)Erik Johnston2020-05-013-6/+6
| | | For in memory streams when fetching updates on workers we need to query the source of the stream, which currently is hard coded to be master. This PR threads through the source instance we received via `POSITION` through to the update function in each stream, which can then be passed to the replication client for in memory streams.
* Use `stream.current_token()` and remove `stream_positions()` (#7172)Erik Johnston2020-05-014-34/+26
| | | | We move the processing of typing and federation replication traffic into their handlers so that `Stream.current_token()` points to a valid token. This allows us to remove `get_streams_to_replicate()` and `stream_positions()`.
* Add instance name to RDATA/POSITION commands (#7364)Erik Johnston2020-04-291-2/+4
| | | | | This is primarily for allowing us to send those commands from workers, but for now simply allows us to ignore echoed RDATA/POSITION commands that we sent (we get echoes of sent commands when using redis). Currently we log a WARNING on the master process every time we receive an echoed RDATA.
* Don't relay REMOTE_SERVER_UP cmds to same conn. (#7352)Erik Johnston2020-04-291-0/+62
| | | | | | | | | | | | | | For direct TCP connections we need the master to relay REMOTE_SERVER_UP commands to the other connections so that all instances get notified about it. The old implementation just relayed to all connections, assuming that sending back to the original sender of the command was safe. This is not true for redis, where commands sent get echoed back to the sender, which was causing master to effectively infinite loop sending and then re-receiving REMOTE_SERVER_UP commands that it sent. The fix is to ensure that we only relay to *other* connections and not to the connection we received the notification from. Fixes #7334.
* Fix limit logic for EventsStream (#7358)Richard van der Hoff2020-04-294-21/+458
| | | | | | | | | | | | | | | | | | | * Factor out functions for injecting events into database I want to add some more flexibility to the tools for injecting events into the database, and I don't want to clutter up HomeserverTestCase with them, so let's factor them out to a new file. * Rework TestReplicationDataHandler This wasn't very easy to work with: the mock wrapping was largely superfluous, and it's useful to be able to inspect the received rows, and clear out the received list. * Fix AssertionErrors being thrown by EventsStream Part of the problem was that there was an off-by-one error in the assertion, but also the limit logic was too simple. Fix it all up and add some tests.
* Add some replication tests (#7278)Erik Johnston2020-04-282-11/+298
| | | | | | | Specifically some tests for the typing stream, which means we test streams that fetch missing updates via HTTP (rather than via the DB). We also shuffle things around a bit so that we create two separate `HomeServer` objects, rather than trying to insert a slaved store into places. Note: `test_typing.py` is heavily inspired by `test_receipts.py`
* Another go at fixing one-word commands (#7326)Richard van der Hoff2020-04-221-0/+42
| | | I messed this up last time I tried (#7239 / e13c6c7).
* Move client command handling out of TCP protocol (#7185)Erik Johnston2020-04-062-24/+15
| | | The aim here is to move the command handling out of the TCP protocol classes and to also merge the client and server command handling (so that we can reuse them for redis protocol). This PR simply moves the client paths to the new `ReplicationCommandHandler`, a future PR will move the server paths too.
* Move catchup of replication streams to worker. (#7024)Erik Johnston2020-03-252-23/+84
| | | This changes the replication protocol so that the server does not send down `RDATA` for rows that happened before the client connected. Instead, the server will send a `POSITION` and clients then query the database (or master out of band) to get up to date.
* Convert `*StreamRow` classes to inner classes (#7116)Richard van der Hoff2020-03-231-2/+2
| | | | | This just helps keep the rows closer to their streams, so that it's easier to see what the format of each stream is.
* Port synapse.replication.tcp to async/await (#6666)Erik Johnston2020-01-161-1/+1
| | | | | | | | | | * Port synapse.replication.tcp to async/await * Newsfile * Correctly document type of on_<FOO> functions as async * Don't be overenthusiastic with the asyncing....

* Fix bug where read-receipts lost their timestamps (#4927)Richard van der Hoff2019-03-254-0/+148
Make sure that they are sent correctly over the replication stream. Fixes: #4898
