* Fix PostgreSQL sometimes using table scans for `event_search` (#14409)Sean Quah2022-11-101-0/+33
| | | | | | | | | | | PostgreSQL may underestimate the number of distinct `room_id`s in `event_search`, which can cause it to use table scans for queries for multiple rooms. Fix this by setting `n_distinct` on the column. Resolves #14402. Signed-off-by: Sean Quah <seanq@matrix.org>

* Fix background update table-scanning `events` (#14374)Richard van der Hoff2022-11-071-8/+8
| | | | | When this background update did its last batch, it would try to update all the events that had been inserted since the bgupdate started, which could cause a table-scan. Make sure we limit the update correctly.

| | | | | | | PostgreSQL 14 changed the behavior of `websearch_to_tsquery` to improve some behaviour. The tests were hitting those edge-cases about handling of hanging double quotes. This fixes the tests to take into account the PostgreSQL version.

* Unified search query syntax using the full-text search capabilities of the ↵James Salter2022-10-253-35/+240
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | underlying DB. (#11635) Support a unified search query syntax which leverages more of the full-text search of each database supported by Synapse. Supports, with the same syntax across Postgresql 11+ and Sqlite: - quoted "search terms" - `AND`, `OR`, `-` (negation) operators - Matching words based on their stem, e.g. searches for "dog" matches documents containing "dogs". This is achieved by - If on postgresql 11+, pass the user input to `websearch_to_tsquery` - If on sqlite, manually parse the query and transform it into the sqlite-specific query syntax. Note that postgresql 10, which is close to end-of-life, falls back to using `phraseto_tsquery`, which only supports a subset of the features. Multiple terms separated by a space are implicitly ANDed. Note that: 1. There is no escaping of full-text syntax that might be supported by the database; e.g. `NOT`, `NEAR`, `*` in sqlite. This runs the risk that people might discover this as accidental functionality and depend on something we don't guarantee. 2. English text is assumed for stemming. To support other languages, either the target language needs to be known at the time of indexing the message (via room metadata, or otherwise), or a separate index for each language supported could be created.

* Fix MSC3030 `/timestamp_to_event` returning `outliers` that it has no idea ↵Eric Eastwood2022-10-181-21/+38
| | | | | | | | | | | | | | | | | | | | | | | | | | | whether are near a gap or not (#14215) Fix MSC3030 `/timestamp_to_event` endpoint returning `outliers` that it has no idea whether are near a gap or not (and therefore unable to determine whether it's actually the closest event). The reason Synapse doesn't know whether an `outlier` is next to a gap is because our gap checks rely on entries in the `event_edges`, `event_forward_extremeties`, and `event_backward_extremities` tables which is [not the case for `outliers`](https://github.com/matrix-org/synapse/blob/2c63cdcc3f1aa4625e947de3c23e0a8133c61286/docs/development/room-dag-concepts.md#outliers). Also fixes MSC3030 Complement `can_paginate_after_getting_remote_event_from_timestamp_to_event_endpoint` test flake. Although this acted flakey in Complement, if `sync_partial_state` raced and beat us before `/timestamp_to_event`, then even if we retried the failing `/context` request it wouldn't work until we made this Synapse change. With this PR, Synapse will never return an `outlier` event so that test will always go and ask over federation. Fix https://github.com/matrix-org/synapse/issues/13944 ### Why did this fail before? Why was it flakey? Sleuthing the server logs on the [CI failure](https://github.com/matrix-org/synapse/actions/runs/3149623842/jobs/5121449357#step:5:5805), it looks like `hs2:/timestamp_to_event` found `$NP6-oU7mIFVyhtKfGvfrEQX949hQX-T-gvuauG6eurU` as an `outlier` event locally. Then when we went and asked for it via `/context`, since it's an `outlier`, it was filtered out of the results -> `You don't have permission to access that event.` This is reproducible when `sync_partial_state` races and persists `$NP6-oU7mIFVyhtKfGvfrEQX949hQX-T-gvuauG6eurU` as an `outlier` before we evaluate `get_event_for_timestamp(...)`. To consistently reproduce locally, just add a delay at the [start of `get_event_for_timestamp(...)`](https://github.com/matrix-org/synapse/blob/cb20b885cb4bd1648581dd043a184d86fc8c7a00/synapse/handlers/room.py#L1470-L1496) so it always runs after `sync_partial_state` completes. ```py from twisted.internet import task as twisted_task d = twisted_task.deferLater(self.hs.get_reactor(), 3.5) await d ``` In a run where it passes, on `hs2`, `get_event_for_timestamp(...)` finds a different event locally which is next to a gap and we request from a closer one from `hs1` which gets backfilled. And since the backfilled event is not an `outlier`, it's returned as expected during `/context`. With this PR, Synapse will never return an `outlier` event so that test will always go and ask over federation.

* Stop getting missing `prev_events` after we already know their signature is ↵Eric Eastwood2022-10-151-0/+54
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | invalid (#13816) While https://github.com/matrix-org/synapse/pull/13635 stops us from doing the slow thing after we've already done it once, this PR stops us from doing one of the slow things in the first place. Related to - https://github.com/matrix-org/synapse/issues/13622 - https://github.com/matrix-org/synapse/pull/13635 - https://github.com/matrix-org/synapse/issues/13676 Part of https://github.com/matrix-org/synapse/issues/13356 Follow-up to https://github.com/matrix-org/synapse/pull/13815 which tracks event signature failures. With this PR, we avoid the call to the costly `_get_state_ids_after_missing_prev_event` because the signature failure will count as an attempt before and we filter events based on the backoff before calling `_get_state_ids_after_missing_prev_event` now. For example, this will save us 156s out of the 185s total that this `matrix.org` `/messages` request. If you want to see the full Jaeger trace of this, you can drag and drop this `trace.json` into your own Jaeger, https://gist.github.com/MadLittleMods/4b12d0d0afe88c2f65ffcc907306b761 To explain this exact scenario around `/messages` -> backfill, we call `/backfill` and first check the signatures of the 100 events. We see bad signature for `$luA4l7QHhf_jadH3mI-AyFqho0U2Q-IXXUbGSMq6h6M` and `$zuOn2Rd2vsC7SUia3Hp3r6JSkSFKcc5j3QTTqW_0jDw` (both member events). Then we process the 98 events remaining that have valid signatures but one of the events references `$luA4l7QHhf_jadH3mI-AyFqho0U2Q-IXXUbGSMq6h6M` as a `prev_event`. So we have to do the whole `_get_state_ids_after_missing_prev_event` rigmarole which pulls in those same events which fail again because the signatures are still invalid. - `backfill` - `outgoing-federation-request` `/backfill` - `_check_sigs_and_hash_and_fetch` - `_check_sigs_and_hash_and_fetch_one` for each event received over backfill - ❗ `$luA4l7QHhf_jadH3mI-AyFqho0U2Q-IXXUbGSMq6h6M` fails with `Signature on retrieved event was invalid.`: `unable to verify signature for sender domain xxx: 401: Failed to find any key to satisfy: _FetchKeyRequest(...)` - ❗ `$zuOn2Rd2vsC7SUia3Hp3r6JSkSFKcc5j3QTTqW_0jDw` fails with `Signature on retrieved event was invalid.`: `unable to verify signature for sender domain xxx: 401: Failed to find any key to satisfy: _FetchKeyRequest(...)` - `_process_pulled_events` - `_process_pulled_event` for each validated event - ❗ Event `$Q0iMdqtz3IJYfZQU2Xk2WjB5NDF8Gg8cFSYYyKQgKJ0` references `$luA4l7QHhf_jadH3mI-AyFqho0U2Q-IXXUbGSMq6h6M` as a `prev_event` which is missing so we try to get it - `_get_state_ids_after_missing_prev_event` - `outgoing-federation-request` `/state_ids` - ❗ `get_pdu` for `$luA4l7QHhf_jadH3mI-AyFqho0U2Q-IXXUbGSMq6h6M` which fails the signature check again - ❗ `get_pdu` for `$zuOn2Rd2vsC7SUia3Hp3r6JSkSFKcc5j3QTTqW_0jDw` which fails the signature check

| | | | | | | | | | | | | | | | | | The root node of a thread (and events related to it) are considered "part of a thread" when validating receipts. This allows clients which show the root node in both the main timeline and the threaded timeline to easily send receipts in either.

Previously, we grabbed thousands of backfill points from the database, then sorted and filtered them in the app. Fetching the 4.6k backfill points for `#matrix:matrix.org` from the database takes ~50ms - ~570ms so it's not like this saves a lot of time 🤷. But it might save us more time now that `get_backfill_points_in_room`/`get_insertion_event_backward_extremities_in_room` are more complicated after https://github.com/matrix-org/synapse/pull/13635 This PR moves the filtering and limiting to the SQL query so we just have less data to work with in the first place.

* Handle remote device list updates during partial join (#13913)Erik Johnston2022-09-283-0/+103
| | | | | | | c.f. #12993 (comment), point 3 This stores all device list updates that we receive while partial joins are ongoing, and processes them once we have the full state. Note: We don't actually process the device lists in the same ways as if we weren't partially joined. Instead of updating the device list remote cache, we simply notify local users that a change in the remote user's devices has happened. I think this is safe as if the local user requests the keys for the remote user and we don't have them we'll simply fetch them as normal.

As an example, disabling the `have_seen_event` cache saves 10 seconds for each `/messages` request in that MSC2716 Complement test because we're not making as many federation requests for `/state` (speeding up `have_seen_event` itself is related to https://github.com/matrix-org/synapse/issues/13625) > > But this will also make `/messages` faster in general so we can include it in the [faster `/messages` milestone](https://github.com/matrix-org/synapse/milestone/11). > > *-- https://github.com/matrix-org/synapse/issues/13856* ### The problem `_invalidate_caches_for_event` doesn't run in monolith mode which means we never even tried to clear the `have_seen_event` and other caches. And even in worker mode, it only runs on the workers, not the master (AFAICT). Additionally there was bug with the key being wrong so `_invalidate_caches_for_event` never invalidates the `have_seen_event` cache even when it does run. Because we were using the `@cachedList` wrong, it was putting items in the cache under keys like `((room_id, event_id),)` with a `set` in a `set` (ex. `(('!TnCIJPKzdQdUlIyXdQ:test', '$Iu0eqEBN7qcyF1S9B3oNB3I91v2o5YOgRNPwi_78s-k'),)`) and we we're trying to invalidate with just `(room_id, event_id)` which did nothing.

The `thread_id` column for `event_push_actions` and `event_push_summary` is backfilled with `"main"` for all existing rows. New entries into `event_push_actions` and `event_push_actions_staging` will get the proper thread ID. `receipts_linearized` and `receipts_graph` also gain a `thread_id` column, which is similar, except `NULL` is a special value meaning the receipt is "unthreaded".

Loading tons of events* in the `/messages` investigation issue](https://github.com/matrix-org/synapse/issues/13356)). There are 3 ways we currently calculate hosts that are in the room: 1. `get_current_state` -> `get_domains_from_state` - Used in `backfill` to calculate `likely_domains` and `/timestamp_to_event` because it was cargo-culted from `backfill` - This one is being eliminated in favor of `get_current_hosts_in_room` in this PR 🕳 1. `get_current_hosts_in_room` - Used for other federation things like sending read receipts and typing indicators 1. `get_hosts_in_room_at_events` - Used when pushing out events over federation to other servers in the `_process_event_queue_loop` Fix https://github.com/matrix-org/synapse/issues/13626 Part of https://github.com/matrix-org/synapse/issues/13356 Mentioned in [internal doc](https://docs.google.com/document/d/1lvUoVfYUiy6UaHB6Rb4HicjaJAU40-APue9Q4vzuW3c/edit#bookmark=id.2tvwz3yhcafh) ### Query performance #### Before The query from `get_current_state` sucks just because we have to get all 80k events. And we see almost the exact same performance locally trying to get all of these events (16s vs 17s): ``` synapse=# SELECT type, state_key, event_id FROM current_state_events WHERE room_id = '!OGEhHVWSdvArJzumhm:matrix.org'; Time: 16035.612 ms (00:16.036) synapse=# SELECT type, state_key, event_id FROM current_state_events WHERE room_id = '!OGEhHVWSdvArJzumhm:matrix.org'; Time: 4243.237 ms (00:04.243) ``` But what about `get_current_hosts_in_room`: When there is 8M rows in the `current_state_events` table, the previous query in `get_current_hosts_in_room` took 13s from complete freshness (when the events were first added). But takes 930ms after a Postgres restart or 390ms if running back to back to back. ```sh $ psql synapse synapse=# \timing on synapse=# SELECT COUNT(DISTINCT substring(state_key FROM '@[^:]*:(.*)$')) FROM current_state_events WHERE type = 'm.room.member' AND membership = 'join' AND room_id = '!OGEhHVWSdvArJzumhm:matrix.org'; count ------- 4130 (1 row) Time: 13181.598 ms (00:13.182) synapse=# SELECT COUNT(*) from current_state_events where room_id = '!OGEhHVWSdvArJzumhm:matrix.org'; count ------- 80814 synapse=# SELECT COUNT(*) from current_state_events; count --------- 8162847 synapse=# SELECT pg_size_pretty( pg_total_relation_size('current_state_events') ); pg_size_pretty ---------------- 4702 MB ``` #### After I'm not sure how long it takes from complete freshness as I only really get that opportunity once (maybe restarting computer but that's cumbersome) and it's not really relevant to normal operating times. Maybe you get closer to the fresh times the more access variability there is so that Postgres caches aren't as exact. Update: The longest I've seen this run for is 6.4s and 4.5s after a computer restart. After a Postgres restart, it takes 330ms and running back to back takes 260ms. ```sh $ psql synapse synapse=# \timing on Timing is on. synapse=# SELECT substring(c.state_key FROM '@[^:]*:(.*)$') as host FROM current_state_events c /* Get the depth of the event from the events table */ INNER JOIN events AS e USING (event_id) WHERE c.type = 'm.room.member' AND c.membership = 'join' AND c.room_id = '!OGEhHVWSdvArJzumhm:matrix.org' GROUP BY host ORDER BY min(e.depth) ASC; Time: 333.800 ms ``` #### Going further To improve things further we could add a `limit` parameter to `get_current_hosts_in_room`. Realistically, we don't need 4k domains to choose from because there is no way we're going to query that many before we a) probably get an answer or b) we give up. Another thing we can do is optimize the query to use a index skip scan: - https://wiki.postgresql.org/wiki/Loose_indexscan - Index Skip Scan, https://commitfest.postgresql.org/37/1741/ - https://www.timescale.com/blog/how-we-made-distinct-queries-up-to-8000x-faster-on-postgresql/

Previously, we returned the same `event` reference that we stored in the cache which downstream code modified in place and added metadata like setting it as an `outlier` and essentially poisoned our cache. Now we always return a copy of the `event` so the original can stay pristine in our cache and re-used for the next cache call.

* Handle race between persisting an event and un-partial stating a room (#13100)Sean Quah2022-07-053-21/+93
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

* Speed up `get_unread_event_push_actions_by_room` (#13005)Erik Johnston2022-06-157-108/+256
| | | | | | | | | | | Fixes #11887 hopefully. The core change here is that `event_push_summary` now holds a summary of counts up until a much more recent point, meaning that the range of rows we need to count in `event_push_actions` is much smaller. This needs two major changes: 1. When we get a receipt we need to recalculate `event_push_summary` rather than just delete it 2. The logic for deleting `event_push_actions` is now divorced from calculating `event_push_summary`. In future it would be good to calculate `event_push_summary` while we persist a new event (it should just be a case of adding one to the relevant rows in `event_push_summary`), as that will further simplify the get counts logic and remove the need for us to periodically update `event_push_summary` in a background job.

These happen rather differently depending on whether we are on Postgres or SQLite. For SQLite, we just rebuild the whole table, copying only the rows we want to keep. For Postgres, we try to do things in the background as much as possible. * Stop populating `event_edges.room_id` and `is_state` We can just rely on the defaults.

It turns out we don't really need that event, and can just work with its ID and metadata, which sidesteps the whole problem.

| | | | | | | | | | Implements the following behind an experimental configuration flag: * A new push rule kind for mutually related events. * A new default push rule (`.m.rule.thread_reply`) under an unstable prefix. This is missing part of MSC3772: * The `.m.rule.thread_reply_to_me` push rule, this depends on MSC3664 / #11804.
