We can follow-up this PR with: 1. Only try to backfill from an event if we haven't tried recently -> https://github.com/matrix-org/synapse/issues/13622 1. When we decide to backfill that event again, process it in the background so it doesn't block and make `/messages` slow when we know it will probably fail again -> https://github.com/matrix-org/synapse/issues/13623 1. Generally track failures everywhere we try and fail to pull an event over federation -> https://github.com/matrix-org/synapse/issues/13700 Fix https://github.com/matrix-org/synapse/issues/13621 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.qv7cj51sv9i5)
2022-09-14Update event push action and receipt tables to support threads. (#13753)Patrick Cloke11-20/+312
Adds a `thread_id` column to the `event_push_actions`, `event_push_actions_staging`, and `event_push_summary` tables. This will notifications to be segmented by the thread in a future pull request. The `thread_id` column stores the root event ID or the special value `"main"`. 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". See MSC3771 and MSC3773 for where this data will be useful.
2022-09-14Use partial indices on SQLIte. (#13802)Patrick Cloke4-5/+59
Partial indices have been supported since SQLite 3.8, but Synapse now requires >= 3.27, so we can enable support for them. This requires rebuilding previous indices which were partial on PostgreSQL, but not on SQLite.

2022-09-14Remove incorrect migration file from `state` logical DB (#13788)David Robertson2-37/+1
* Remove incorrect migration file from `state` logical DB The table `ex_outlier_stream` is part of the `main` logical DB; it should not have been created in the `state` logical DB. We remove this migration now as a tidy-up. Note: we cannot `DROP TABLE IF EXISTS ex_outlier_stream` in a new migration, because some (most) instances of Synapse host both of these logical DBs on the same DB cluster. * Changelog
2022-09-14Fix bug in device list caching when remote users leave rooms (#13749)Sean Quah5-15/+51
When a remote user leaves the last room shared with the homeserver, we have to mark their device list as unsubscribed, otherwise we would hold on to a stale device list in our cache. Crucially, the device list would remain cached even after the remote user rejoined the room, which could lead to E2EE failures until the next change to the remote user's device list. Fixes #13651.

2022-09-09Concurrently collect room unread counts for push badges (#13765)Nick Mills-Barrett2-3/+11
Most of the time this function is heavily cached, but when that isn't the case fetching the counts room by room slows down push delivery on users with many (thousands) of rooms. Signed off by Nick @ Beeper.
2022-09-09Tag trace with instance name (#13761)Eric Eastwood3-2/+12
We tag the Synapse instance name so that it's an easy jumping off point into the logs. Can also be used to filter for an instance that is under load. As suggested by @clokep and @reivilibre in, - https://github.com/matrix-org/synapse/pull/13729#discussion_r964719258 - https://github.com/matrix-org/synapse/pull/13729#discussion_r964733578
2022-09-09Strip number suffix from instance name to consolidate services that traces ↵Eric Eastwood2-1/+13
are spread over (#13729) The problem with many services is that it makes it hard to find which service has the trace you want, see https://github.com/jaegertracing/jaeger-ui/issues/985 Previously, we split traces out into services based on their instance name like `matrix.org client_reader-1`, etc but there are many worker instances of the same `client_reader` so there is a lot to click through. With this PR, all of the traces are just collected under the worker type like `client_reader`, `event_persister` 😇 Note: A Synapse worker instance name is an opaque string with the number convention only being our own thing for the `matrix.org` deployment. But seems pretty sensible to group things this way.
2022-09-09Use an upsert for `receipts_graph`. (#13752)Patrick Cloke2-8/+5

2022-09-07Instrument `get_metadata_for_events` for tracing (#13730)Eric Eastwood2-0/+3

For `#matrix:matrix.org`, it's called with 77k `state_events` which means 77 calls to the database and takes 28 seconds.

The `room_id` field represented the parent space for each room and was made redundant by changes in the API shape where the `children_state` is now nested underneath each `room`. The room ID of each child is in the `state_key` field and is still available.

2022-08-31Change dpkg-statoverride to use --force-statoverride-add (#13638)Jörg Behrmann2-1/+2
The --force flag of dpkg-statoverride has been deprecated (apparently starting with the dpkg version in Debian buster). It offers --force-all as q quick fix, but the usage in the Debian postinst script is probably covered by --force-statoverride-add.

2022-08-30Fix bug where we wedge media plugins if clients disconnect early (#13660)Erik Johnston2-19/+22
We incorrectly didn't use the returned `Responder` if the client had disconnected, which meant that the resource used by the Responder wasn't correctly released. In particular, this exhausted the thread pools so that *all* requests timed out.
2022-08-30Do not wait for background updates to complete do expire URL cache. (#13657)Patrick Cloke2-4/+1
Media downloaded as part of a URL preview is normally deleted after two days. However, while a background database migration is running, the process is stopped. A long-running database migration can therefore cause the media store to fill up with old preview files. This logic was added in #2697 to make sure that we didn't try to run the expiry without an index on `local_media_repository.created_ts`; the original logic that needs that index was added in #2478 (in `get_url_cache_media_before`, as amended by 93247a424a5068b088567fa98b6990e47608b7cb), and is still present. Given that the background update was added before Synapse v1.0.0, just drop this check and assume the index exists.

2022-08-30Optimize how we calculate `likely_domains` during backfill (#13575)Eric Eastwood5-70/+89
Optimize how we calculate `likely_domains` during backfill because I've seen this take 17s in production just to `get_current_state` which is used to `get_domains_from_state` (see case [*2. 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/

2022-08-24When loading current ids, sort by `stream_id` to avoid incorrect overwrite ↵Eric Eastwood2-2/+12
and avoid errors caused by sorting alphabetical instance name which can be `null` (#13585) When loading current ids, sort by stream ID so that we don't want to overwrite the `current_position` of an instance to a lower stream ID than we're actually at ([discussion](https://github.com/matrix-org/synapse/pull/13585#discussion_r951795379)). Previously, it sorted alphabetically by instance name which can be `null` and throw errors but more importantly, accomplishes nothing. Fixes the following startup error which is why I started looking into this area: ``` $ poetry run synapse_homeserver --config-path homeserver.yaml **************************************************************** Error during initialisation: '<' not supported between instances of 'NoneType' and 'str' There may be more information in the logs. **************************************************************** ``` Somehow my database ended up looking like the following, notice the `instance_name` is `null` in the db, and we can't sort `NoneType` things. Another question is why do we see the `instance_name` as `null` sometimes instead of `master` in monolith mode? ``` $ psql synapse synapse=# SELECT * FROM stream_positions; stream_name | instance_name | stream_id -----------------+---------------+----------- account_data | master | 1242 events | master | 1787 to_device | master | 58 presence_stream | master | 485638 receipts | master | 341 backfill | master | -139106 (6 rows) synapse=# SELECT instance_name, stream_id FROM receipts_linearized; instance_name | stream_id ---------------+----------- | 211 | 3 | 4 | 212 | 213 | 224 | 228 | 164 | 313 | 253 | 38 | 321 | 324 | 189 | 192 | 193 | 194 | 195 | 197 | 198 | 275 | 79 | 339 | 340 | 82 | 341 | 84 | 85 | 91 | 119 ```
