* Fix HTTP repl response to use minimum token (#16578)Erik Johnston2023-10-301-1/+1

* Fix bug where a new writer advances their token too quickly (#16473)Erik Johnston2023-10-231-1/+1
| | | | | | | | | | | | | | | | | | | * Fix bug where a new writer advances their token too quickly When starting a new writer (for e.g. persisting events), the `MultiWriterIdGenerator` doesn't have a minimum token for it as there are no rows matching that new writer in the DB. This results in the the first stream ID it acquired being announced as persisted *before* it actually finishes persisting, if another writer gets and persists a subsequent stream ID. This is due to the logic of setting the minimum persisted position to the minimum known position of across all writers, and the new writer starts off not being considered. * Fix sending out POSITIONs when our token advances without update Broke in #14820 * For replication HTTP requests, only wait for minimal position
* Clean up logging on event persister endpoints (#16488)Richard van der Hoff2023-10-142-6/+13

* Recheck if remote device is cached before requesting it (#16252)Erik Johnston2023-09-071-2/+2
| | | | This fixes a bug where we could get stuck re-requesting the device over replication again and again.
* Cache device resync requests over replication (#16241)David Robertson2023-09-041-1/+1
|
* Pass the device ID around in the presence handler (#16171)Patrick Cloke2023-08-281-4/+7
| | | | | | Refactoring to pass the device ID (in addition to the user ID) through the presence handler (specifically the `user_syncing`, `set_state`, and `bump_presence_active_time` methods and their replication versions).
* Combine logic about not overriding BUSY presence. (#16170)Patrick Cloke2023-08-281-5/+5
| | | | | | | | | | | | | Simplify some of the presence code by reducing duplicated code between worker & non-worker modes. The main change is to push some of the logic from `user_syncing` into `set_state`. This is done by passing whether the user is setting the presence via a `/sync` with a new `is_sync` flag to `set_state`. If this is `true` some additional logic is performed: * Don't override `busy` presence. * Update the `last_user_sync_ts`. * Never update the status message.
* Clarify comment on key uploads over replication (#16016)Shay2023-07-271-2/+2

* Use a custom scheme & the worker name for replication requests. (#15578)Jason Little2023-05-231-12/+6
| | | | | | | | All the information needed is already in the `instance_map`, so use that instead of passing the hostname / IP & port manually for each replication request. This consolidates logic for future improvements of using e.g. UNIX sockets for workers.
* Remove `worker_replication_*` settings (#15491)Jason Little2023-05-111-11/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Add master to the instance_map as part of Complement, have ReplicationEndpoint look at instance_map for master. * Fix typo in drive by. * Remove unnecessary worker_replication_* bits from unit tests and add master to instance_map(hopefully in the right place) * Several updates: 1. Switch from master to main for naming the main process in the instance_map. Add useful constants for easier adjustment of names in the future. 2. Add backwards compatibility for worker_replication_* to allow time to transition to new style. Make sure to prioritize declaring main directly on the instance_map. 3. Clean up old comments/commented out code. 4. Adjust unit tests to match with new code. 5. Adjust Complement setup infrastructure to only add main to the instance_map if workers are used and remove now unused options from the worker.yaml template. * Initial Docs upload * Changelog * Missed some commented out code that can go now * Remove TODO comment that no longer holds true. * Fix links in docs * More docs * Remove debug logging * Apply suggestions from code review Co-authored-by: reivilibre <olivier@librepush.net> * Apply suggestions from code review Co-authored-by: reivilibre <olivier@librepush.net> * Update version to latest, include completeish before/after examples in upgrade notes. * Fix up and docs too --------- Co-authored-by: reivilibre <olivier@librepush.net>
* HTTP Replication Client (#15470)Jason Little2023-05-091-1/+1
| | | | | | Separate out a HTTP client for replication in preparation for also supporting using UNIX sockets. The major difference from the base class is that this does not use treq to handle HTTP requests.
* Remove legacy code of single user device resync api (#15418)Alok Kumar Singh2023-04-211-57/+0

* Have replication clients remove _INT_STREAM_POS (#15309)David Robertson2023-03-221-1/+1
| | | | | | | | | | | | | | | | | | | * Have replication clients remove _INT_STREAM_POS Suppose worker A makes an internal http request from worker B. B may make changes that A later learns about over replication. We want A's request to block until it has seen those changes—mainly to ensure A's caches are invalidated promptly. This helps provide read-after-write consistency, eliminating entire categories of races and test flakes. To implement this, B includes a top-level field `_INT_STREAM_POS` in its response JSON. Roughly speaking, the field's value tells A what to wait for. But we weren't removing that internal field before A's request completed! Introduced in https://github.com/matrix-org/synapse/pull/14820. Fixes #15308. * Changelog

* Reduce max time we wait for stream positions (#14881)Erik Johnston2023-01-201-2/+0
| | | | | | Now that we wait for stream positions whenever we do a HTTP replication hit, we need to be less brutal in the case where we do timeout (as we have bugs around this).
* Wait for streams to catch up when processing HTTP replication. (#14820)Erik Johnston2023-01-1813-89/+140
| | | | This should hopefully mitigate a class of races where data gets out of sync due a HTTP replication request racing with the replication streams.

* Faster room joins: fix race in recalculation of current room state (#13151)Sean Quah2022-07-072-0/+77
| | | | | | | | | | | Bounce recalculation of current state to the correct event persister and move recalculation of current state into the event persistence queue, to avoid concurrent updates to a room's current state.

* Handle race between persisting an event and un-partial stating a room (#13100)Sean Quah2022-07-052-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Whenever we want to persist an event, we first compute an event context, which includes the state at the event and a flag indicating whether the state is partial. After a lot of processing, we finally try to store the event in the database, which can fail for partial state events when the containing room has been un-partial stated in the meantime. We detect the race as a foreign key constraint failure in the data store layer and turn it into a special `PartialStateConflictError` exception, which makes its way up to the method in which we computed the event context. To make things difficult, the exception needs to cross a replication request: `/fed_send_events` for events coming over federation and `/send_event` for events from clients. We transport the `PartialStateConflictError` as a `409 Conflict` over replication and turn `409`s back into `PartialStateConflictError`s on the worker making the request. All client events go through `EventCreationHandler.handle_new_client_event`, which is called in *a lot* of places. Instead of trying to update all the code which creates client events, we turn the `PartialStateConflictError` into a `429 Too Many Requests` in `EventCreationHandler.handle_new_client_event` and hope that clients take it as a hint to retry their request. On the federation event side, there are 7 places which compute event contexts. 4 of them use outlier event contexts: `FederationEventHandler._auth_and_persist_outliers_inner`, `FederationHandler.do_knock`, `FederationHandler.on_invite_request` and `FederationHandler.do_remotely_reject_invite`. These events won't have the partial state flag, so we do not need to do anything for then. The remaining 3 paths which create events are `FederationEventHandler.process_remote_join`, `FederationEventHandler.on_send_membership_event` and `FederationEventHandler._process_received_pdu`. We can't experience the race in `process_remote_join`, unless we're handling an additional join into a partial state room, which currently blocks, so we make no attempt to handle it correctly. `on_send_membership_event` is only called by `FederationServer._on_send_membership_event`, so we catch the `PartialStateConflictError` there and retry just once. `_process_received_pdu` is called by `on_receive_pdu` for incoming events and `_process_pulled_event` for backfill. The latter should never try to persist partial state events, so we ignore it. We catch the `PartialStateConflictError` in `on_receive_pdu` and retry just once. Refering to the graph of code paths in https://github.com/matrix-org/synapse/issues/12988#issuecomment-1156857648 may make the above make more sense. Signed-off-by: Sean Quah <seanq@matrix.org>

* Respect the `@cancellable` flag for `ReplicationEndpoint`s (#12700)Sean Quah2022-05-111-2/+19
| | | | | | | | | While `ReplicationEndpoint`s register themselves via `JsonResource`, they pass a method that calls the handler, instead of the handler itself, to `register_paths`. As a result, `JsonResource` will not correctly pick up the `@cancellable` flag and we have to apply it ourselves. Signed-off-by: Sean Quah <seanq@element.io>

* Fix opentracing and Prometheus metrics for replication requests (#10996)Sean Quah2021-10-121-76/+78
| | | | | | | | | | | | | | | | | | | | | | | | This commit fixes two bugs to do with decorators not instrumenting `ReplicationEndpoint`'s `send_request` correctly. There are two decorators on `send_request`: Prometheus' `Gauge.track_inprogress()` and Synapse's `opentracing.trace`. `Gauge.track_inprogress()` does not have any support for async functions when used as a decorator. Since async functions behave like regular functions that return coroutines, only the creation of the coroutine was covered by the metric and none of the actual body of `send_request`. `Gauge.track_inprogress()` returns a regular, non-async function wrapping `send_request`, which is the source of the next bug. The `opentracing.trace` decorator would normally handle async functions correctly, but since the wrapped `send_request` is a non-async function, the decorator ends up suffering from the same issue as `Gauge.track_inprogress()`: the opentracing span only measures the creation of the coroutine and none of the actual function body. Using `Gauge.track_inprogress()` as a context manager instead of a decorator resolves both bugs.

* Extend `ResponseCache` to pass a context object into the callback (#10157)Richard van der Hoff2021-06-142-4/+4
| | | | | This is the first of two PRs which seek to address #8518. This first PR lays the groundwork by extending ResponseCache; a second PR (#10158) will update the SyncHandler to actually use it, and fix the bug. The idea here is that we allow the callback given to ResponseCache.wrap to decide whether its result should be cached or not. We do that by (optionally) passing a ResponseCacheContext into it, which it can modify.

* Make RateLimiter class check for ratelimit overrides (#9711)Erik Johnston2021-03-301-1/+1
| | | | | | | This should fix a class of bug where we forget to check if e.g. the appservice shouldn't be ratelimited. We also check the `ratelimit_override` table to check if the user has ratelimiting disabled. That table is really only meant to override the event sender ratelimiting, so we don't use any values from it (as they might not make sense for different rate limits), but we do infer that if ratelimiting is disabled for the user we should disabled all ratelimits. Fixes #9663
* Prep work for removing `outlier` from `internal_metadata` (#9411)Richard van der Hoff2021-03-172-1/+6
| | | | | | | | | | | | * Populate `internal_metadata.outlier` based on `events` table Rather than relying on `outlier` being in the `internal_metadata` column, populate it based on the `events.outlier` column. * Move `outlier` out of InternalMetadata._dict Ultimately, this will allow us to stop writing it to the database. For now, we have to grandfather it back in so as to maintain compatibility with older versions of Synapse.
* Fix the auth provider on the logins metric (#9573)Richard van der Hoff2021-03-101-2/+2
| | | | | We either need to pass the auth provider over the replication api, or make sure we report the auth provider on the worker that received the request. I've gone with the latter.

| | | | | This PR grew out of #6739, and adds typing to some method arguments You'll notice that there are a lot of `# type: ignores` in here. This is due to the base methods not matching the overloads here. This is necessary to stop mypy complaining, but a better solution is #8828.
* Generalise _maybe_store_room_on_invite (#8754)Andrew Morgan2020-11-131-5/+5
| | | | | | | | | There's a handy function called maybe_store_room_on_invite which allows us to create an entry in the rooms table for a room and its version for which we aren't joined to yet, but we can reference when ingesting events about. This is currently used for invites where we receive some stripped state about the room and pass it down via /sync to the client, without us being in the room yet. There is a similar requirement for knocking, where we will eventually do the same thing, and need an entry in the rooms table as well. Thus, reusing this function works, however its name needs to be generalised a bit. Separated out from #6739.
* Add ability for access tokens to belong to one user but grant access to ↵Erik Johnston2020-10-292-6/+3
| | | | | | | | | | another user. (#8616) We do it this way round so that only the "owner" can delete the access token (i.e. `/logout/all` by the "owner" also deletes that token, but `/logout/all` by the "target user" doesn't). A future PR will add an API for creating such a token. When the target user and authenticated entity are different the `Processed request` log line will be logged with a: `{@admin:server as @bob:server} ...`. I'm not convinced by that format (especially since it adds spaces in there, making it harder to use `cut -d ' '` to chop off the start of log lines). Suggestions welcome.

| * Typing worker needs to handle stream update requests (#7967)Erik Johnston2020-07-281-1/+1
| | | | | | | | | | IIRC this doesn't break tests because its only hit on reconnection, or something. Basically, when a process needs to fetch missing updates for the `typing` stream it needs to query the writer instance via HTTP (as we don't write typing notifications to the DB), the problem was that the endpoint (`streams`) was only registered on master and specifically not on the typing writer worker.

* Generate real events when we reject invites (#7804)Richard van der Hoff2020-07-091-67/+25
| | | | | | | | Fixes #2181. The basic premise is that, when we fail to reject an invite via the remote server, we can generate our own out-of-band leave event and persist it as an outlier, so that we have something to send to the client.

|
* Add ability to wait for replication streams (#7542)Erik Johnston2020-05-224-16/+20
| | | | | | | The idea here is that if an instance persists an event via the replication HTTP API it can return before we receive that event over replication, which can lead to races where code assumes that persisting an event immediately updates various caches (e.g. current state of the room). Most of Synapse doesn't hit such races, so we don't do the waiting automagically, instead we do so where necessary to avoid unnecessary delays. We may decide to change our minds here if it turns out there are a lot of subtle races going on. People probably want to look at this commit by commit.
* Allow ReplicationRestResource to be added to workers (#7515)Erik Johnston2020-05-181-5/+8
| | | This allows workers to talk to each other over HTTP replication.
* Add `instance_map` config and route replication calls (#7495)Erik Johnston2020-05-141-6/+15
|
* Have all instances correctly respond to REPLICATE command. (#7475)Erik Johnston2020-05-131-2/+2
| | | | | Before all streams were only written to from master, so only master needed to respond to `REPLICATE` commands. Before all instances wrote to the cache invalidation stream, but didn't respond to `REPLICATE`. This was a bug, which could lead to missed rows from cache invalidation stream if an instance is restarted, however all the caches would be empty in that case so it wasn't a problem.
* Thread through instance name to replication client. (#7369)Erik Johnston2020-05-012-2/+21
| | | 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.
* Remove 'limit' param from `get_repl_stream_updates` APIRichard van der Hoff2020-04-231-5/+7
| | | | | there doesn't seem to be much point in passing this limit all around, since both sides agree it's meant to be 100.
* Move catchup of replication streams to worker. (#7024)Erik Johnston2020-03-252-0/+80
| | | 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.
* Store room_versions in EventBase objects (#6875)Richard van der Hoff2020-03-052-8/+19
| | | | | | | This is a bit fiddly because it all has to be done on one fell swoop: * Wherever we create a new event, pass in the room version (and check it matches the format version) * When we prune an event, use the room version of the unpruned event to create the pruned version. * When we pass an event over the replication protocol, pass the room version over alongside it, and use it when deserialising the event again.
* Store room version on invite (#6983)Richard van der Hoff2020-02-262-2/+36
| | | | | When we get an invite over federation, store the room version in the rooms table. The general idea here is that, when we pull the invite out again, we'll want to know what room_version it belongs to (so that we can later redact it if need be). So we need to store it somewhere...

| * Fix caching devices for remote servers in worker.Erik Johnston2019-11-052-1/+78
| | | | | | | | | | | | | | | | When the `/keys/query` API is hit on client_reader worker Synapse may decide that it needs to resync some remote deivces. Usually this happens on master, and then gets cached. However, that fails on workers and so it falls back to fetching devices from remotes directly, which may in turn fail if the remote is down.
