* Fix MultiWriteIdGenerator's handling of restarts. (#8374)Erik Johnston2020-09-241-0/+2
| | | | | | | | | | | | | | | | | | | On startup `MultiWriteIdGenerator` fetches the maximum stream ID for each instance from the table and uses that as its initial "current position" for each writer. This is problematic as a) it involves either a scan of events table or an index (neither of which is ideal), and b) if rows are being persisted out of order elsewhere while the process restarts then using the maximum stream ID is not correct. This could theoretically lead to race conditions where e.g. events that are persisted out of order are not sent down sync streams. We fix this by creating a new table that tracks the current positions of each writer to the stream, and update it each time we finish persisting a new entry. This is a relatively small overhead when persisting events. However for the cache invalidation stream this is a much bigger relative overhead, so instead we note that for invalidation we don't actually care about reliability over restarts (as there's no caches to invalidate) and simply don't bother reading and writing to the new table in that particular case.
* Add EventStreamPosition type (#8388)Erik Johnston2020-09-241-3/+9
| | | | | | | | | | | | | | The idea is to remove some of the places we pass around `int`, where it can represent one of two things: 1. the position of an event in the stream; or 2. a token that partitions the stream, used as part of the stream tokens. The valid operations are then: 1. did a position happen before or after a token; 2. get all events that happened before or after a token; and 3. get all events between two tokens. (Note that we don't want to allow other operations as we want to change the tokens to be vector clocks rather than simple ints)
* Simplify super() calls to Python 3 syntax. (#8344)Patrick Cloke2020-09-1819-25/+25
| | | | | | | This converts calls like super(Foo, self) -> super(). Generated with: sed -i "" -Ee 's/super\([^\(]+\)/super()/g' **/*.py

* Use slots in attrs classes where possible (#8296)Patrick Cloke2020-09-141-2/+2
| | | | | slots use less memory (and attribute access is faster) while slightly limiting the flexibility of the class attributes. This focuses on objects which are instantiated "often" and for short periods of time.

* Add experimental support for sharding event persister. Again. (#8294)Erik Johnston2020-09-143-6/+12
| | | | | | This is *not* ready for production yet. Caveats: 1. We should write some tests... 2. The stream token that we use for events can get stalled at the minimum position of all writers. This means that new events may not be processed and e.g. sent down sync streams if a writer isn't writing or is slow.
* Clean up `Notifier.on_new_room_event` code path (#8288)Erik Johnston2020-09-101-6/+3
| | | | | | | | | | | | | The idea here is that we pass the `max_stream_id` to everything, and only use the stream ID of the particular event to figure out *when* the max stream position has caught up to the event and we can notify people about it. This is to maintain the distinction between the position of an item in the stream (i.e. event A has stream ID 513) and a token that can be used to partition the stream (i.e. give me all events after stream ID 352). This distinction becomes important when the tokens are more complicated than a single number, which they will be once we start tracking the position of multiple writers in the tokens. The valid operations here are: 1. Is a position before or after a token 2. Fetching all events between two tokens 3. Merging multiple tokens to get the "max", i.e. `C = max(A, B)` means that for all positions P where P is before A *or* before B, then P is before C. Future PR will change the token type to a dedicated type.
* Remove some unused distributor signals (#8216)Patrick Cloke2020-09-091-6/+4
| | | | | Removes the `user_joined_room` and stops calling it since there are no observers. Also cleans-up some other unused signals and related code.
* Fixup pusher pool notifications (#8287)Erik Johnston2020-09-091-1/+2
| | | | | `pusher_pool.on_new_notifications` expected a min and max stream ID, however that was not what we were passing in. Instead, let's just pass it the current max stream ID and have it track the last stream ID it got passed. I believe that it mostly worked as we called the function for every event. However, it would break for events that got persisted out of order, i.e, that were persisted but the max stream ID wasn't incremented as not all preceding events had finished persisting, and push for that event would be delayed until another event got pushed to the effected users.

* Move and rename `get_devices_with_keys_by_user` (#8204)Richard van der Hoff2020-09-011-0/+3
| | | | | | | | | | | | | | | | | | * Move `get_devices_with_keys_by_user` to `EndToEndKeyWorkerStore` this seems a better fit for it. This commit simply moves the existing code: no other changes at all. * Rename `get_devices_with_keys_by_user` to better reflect what it does. * get_device_stream_token abstract method To avoid referencing fields which are declared in the derived classes, make `get_device_stream_token` abstract, and define that in the classes which define `_device_list_id_gen`.
* Fix `wait_for_stream_position` for multiple waiters. (#8196)Erik Johnston2020-08-281-4/+2
| | | | | | This fixes a bug where having multiple callers waiting on the same stream and position will cause it to try and compare two deferreds, which fails (due to the sorted list having an entry of `Tuple[int, Deferred]`).

| | | | | It's just a thin wrapper around two ID gens to make `get_current_token` and `get_next` return tuples. This can easily be replaced by calling the appropriate methods on the underlying ID gens directly.

* Separate `get_current_token` into two. (#8113)Erik Johnston2020-08-192-1/+9
| | | | | | | | | | | | The function is used for two purposes: 1) for subscribers of streams to get a token they can use to get further updates with, and 2) for replication to track position of the writers of the stream. For streams with a single writer the two scenarios produce the same result, however the situation becomes complicated for streams with multiple writers. The current `MultiWriterIdGenerator` does not correctly handle the first case (which is not an issue as its only used for the `caches` stream which nothing subscribes to outside of replication).

|\ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Synapse 1.18.0rc2 (2020-07-28) ============================== Bugfixes -------- - Fix an `AssertionError` exception introduced in v1.18.0rc1. ([\#7876](https://github.com/matrix-org/synapse/issues/7876)) - Fix experimental support for moving typing off master when worker is restarted, which is broken in v1.18.0rc1. ([\#7967](https://github.com/matrix-org/synapse/issues/7967)) Internal Changes ---------------- - Further optimise queueing of inbound replication commands. ([\#7876](https://github.com/matrix-org/synapse/issues/7876))
| * 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.
| * Handle replication commands synchronously where possible (#7876)Richard van der Hoff2020-07-273-86/+111
| | | | | | Most of the stuff we do for replication commands can be done synchronously. There's no point spinning up background processes if we're not going to need them.

* Fix typing replication not being handled on master (#7959)Erik Johnston2020-07-271-0/+8
| | | | | | | | | | | | | | | | Handling of incoming typing stream updates from replication was not hooked up on master, effecting set ups where typing was handled on a different worker. This is really only a problem if the master process is also handling sync requests, which is unlikely for those that are at the stage of moving typing off. The other observable effect is that if a worker restarts or a replication connect drops then the typing worker will issue a `POSITION typing`, triggering master process to try and stream *all* typing updates from position 0. Fixes #7907

|
* Stop using 'device_max_stream_id' (#7882)Erik Johnston2020-07-171-1/+1
| | | | | It serves no purpose and updating everytime we write to the device inbox stream means all such transactions will conflict, causing lots of transaction failures and retries.
* Optimise queueing of inbound replication commands (#7861)Richard van der Hoff2020-07-161-116/+215
| | | | | | | | | | | When we get behind on replication, we tend to stack up background processes behind a linearizer. Bg processes are heavy (particularly with respect to prometheus metrics) and linearizers aren't terribly efficient once the queue gets long either. A better approach is to maintain a queue of requests to be processed, and nominate a single process to work its way through the queue. Fixes: #7444

* 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.

* Fix bug in account data replication stream. (#7656)Erik Johnston2020-06-092-3/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | * Ensure account data stream IDs are unique. The account data stream is shared between three tables, and the maximum allocated ID was tracked in a dedicated table. Updating the max ID happened outside the transaction that allocated the ID, leading to a race where if the server was restarted then the same ID could be allocated but the max ID failed to be updated, leading it to be reused. The ID generators have support for tracking across multiple tables, so we may as well use that instead of a dedicated table. * Fix bug in account data replication stream. If the same stream ID was used in both global and room account data then the getting updates for the replication stream would fail due to `heapq.merge(..)` trying to compare a `str` with a `None`. (This is because you'd have two rows like `(534, '!room')` and `(534, None)` from the room and global account data tables). Fix is just to order by stream ID, since we don't rely on the ordering beyond that. The bug where stream IDs can be reused should be fixed now, so this case shouldn't happen going forward.

|
* Add ability to wait for replication streams (#7542)Erik Johnston2020-05-225-18/+108
| | | | | | | 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.

| | | | | | | | | | | | 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.
* | Move event stream handling out of slave store. (#7491)Erik Johnston2020-05-152-97/+0
|/ | | | | This allows us to have the logic on both master and workers, which is necessary to move event persistence off master. We also combine the instantiation of ID generators from DataStore and slave stores to the base worker stores. This allows us to select which process writes events independently of the master/worker splits.
* Move EventStream handling into default ReplicationDataHandler (#7493)Erik Johnston2020-05-141-4/+33

|
* Have all instances correctly respond to REPLICATE command. (#7475)Erik Johnston2020-05-133-48/+50
| | | | | 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.
* Fix Redis reconnection logic (#7482)Erik Johnston2020-05-132-2/+14
| | | Proactively send out `POSITION` commands (as if we had just received a `REPLICATE`) when we connect to Redis. This is important as other instances won't notice we've connected to issue a `REPLICATE` command (unlike for direct TCP connections). This is only currently an issue if master process reconnects without restarting (if it restarts then it won't have written anything and so other instances probably won't have missed anything).

* | Thread through instance name to replication client. (#7369)Erik Johnston2020-05-017-29/+90
| | | | | | 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.

| | | | | 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 Johnston2020-04-293-16/+51
| | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | * 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.

* Fix EventsStream raising assertions when it falls behindRichard van der Hoff2020-04-241-18/+95
| | | | | | | | | | Figuring out how to correctly limit updates from this stream without dropping entries is far more complicated than just counting the number of rows being returned. We need to consider each query separately and, if any one query hits the limit, truncate the results from the others. I think this also fixes some potentially long-standing bugs where events or state changes could get missed if we hit the limit on either query.

* Stop the master relaying USER_SYNC for other workers (#7318)Richard van der Hoff2020-04-222-12/+10
| | | | | | | Long story short: if we're handling presence on the current worker, we shouldn't be sending USER_SYNC commands over replication. In an attempt to figure out what is going on here, I ended up refactoring some bits of the presencehandler code, so the first 4 commits here are non-functional refactors to move this code slightly closer to sanity. (There's still plenty to do here :/). Suggest reviewing individual commits. Fixes (I hope) #7257.

| | | | | | | The general idea here is to get rid of the type: ignore annotations on all of the current_token and update_function assignments, which would have caught #7290. After a bit of experimentation, it seems like the least-awful way to do this is to pass the offending functions in as parameters to the Stream constructor. Unfortunately that means that the concrete implementations no longer have the same constructor signature as Stream itself, which means that it gets hard to correctly annotate STREAMS_MAP. I've also introduced a couple of new types, to take out some duplication.
* Fix 'generator object is not subscriptable' error (#7290)Richard van der Hoff2020-04-161-1/+2
| | | | | | Some of the query functions return generators rather than lists, so we can't index into the result. Happily we already have a copy of the results. (think this was introduced in #7024)
* Handle one-word replication commands correctlyRichard van der Hoff2020-04-071-3/+11
| | | | | `REPLICATE` is now a valid command, and it's nice if you can issue it from the console without remembering to call it `REPLICATE ` with a trailing space.
* Fix warnings about not calling superclass constructorRichard van der Hoff2020-04-071-15/+24
| | | | | | Separate `SimpleCommand` from `Command`, so that things which don't want to use the `data` property don't have to, and thus fix the warnings PyCharm was giving me about not calling `__init__` in the base class.

* Fix race in replication (#7226)Erik Johnston2020-04-072-29/+47

* Move server command handling out of TCP protocol (#7187)Erik Johnston2020-04-073-269/+236
| | | This completes the merging of server and client command processing.
* Move client command handling out of TCP protocol (#7185)Erik Johnston2020-04-064-322/+336
| | | 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.
* Remove connections per replication stream metric. (#7195)Erik Johnston2020-04-011-16/+0
| | | | | This broke in a recent PR (#7024) and is no longer useful due to all replication clients implicitly subscribing to all streams, so let's just remove it.
* Remove usage of "conn_id" for presence. (#7128)Erik Johnston2020-03-304-18/+50
| | | | | | | | | | | | | | | | * Remove `conn_id` usage for UserSyncCommand. Each tcp replication connection is assigned a "conn_id", which is used to give an ID to a remotely connected worker. In a redis world, there will no longer be a one to one mapping between connection and instance, so instead we need to replace such usages with an ID generated by the remote instances and included in the replicaiton commands. This really only effects UserSyncCommand. * Add CLEAR_USER_SYNCS command that is sent on shutdown. This should help with the case where a synchrotron gets restarted gracefully, rather than rely on 5 minute timeout.
* Move catchup of replication streams to worker. (#7024)Erik Johnston2020-03-2512-232/+319
| | | 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 Hoff2020-03-232-96/+101

* | Store room_versions in EventBase objects (#6875)Richard van der Hoff2020-03-052-8/+19

* 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...

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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | This is the first tranche of support for room versioning. It includes: * setting the default room version in the config file * new room_version param on the createRoom API * storing the version of newly-created rooms in the m.room.create event * fishing the version of existing rooms out of the m.room.create event

| * Kill off MatrixCodeMessageExceptionRichard van der Hoff2018-08-012-16/+12
| | | | | | | | | | | | | | | | | | | | | | This code brings the SimpleHttpClient into line with the MatrixFederationHttpClient by having it raise HttpResponseExceptions when a request fails (rather than trying to parse for matrix errors and maybe raising MatrixCodeMessageException). Then, whenever we were checking for MatrixCodeMessageException and turning them into SynapseErrors, we now need to check for HttpResponseExceptions and call to_synapse_error.

* 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
| | | | | This will reduce the number of "Starting db connection from sentinel context" warnings, and will help with our metrics.

* Use stream cache in get_linearized_receipts_for_roomErik Johnston2018-07-101-1/+1
