@pacien pacien commented Jul 2, 2023

Old device entries for the same user were being removed in individual
SQL commands, making the batch take way longer than necessary.

This combines the commands into a single one with a IN/ANY clause.

Example of log entry before the change, regularly observed with
"log_min_duration_statement = 10000" in PostgreSQL's config:

LOG:  duration: 42538.282 ms  statement:
DELETE FROM device_lists_stream
WHERE user_id = '@someone' AND device_id = 'someid1'
AND stream_id < 123456789
;
DELETE FROM device_lists_stream
WHERE user_id = '@someone' AND device_id = 'someid2'
AND stream_id < 123456789
;
[repeated for each device ID of that user, potentially a lot...]

With the patch applied on my instance for the past couple of days, I
no longer notice overly long statements of that particular kind.

Merge tag 'v1.88.0' into develop
55a9f8a 
This release
 - raises the minimum supported version of Python to 3.8, as Python 3.7 is now [end-of-life](https://devguide.python.org/versions/), and
 - removes deprecated config options related to worker deployment.

See [the upgrade notes](https://github.com/matrix-org/synapse/blob/release-v1.88/docs/upgrade.md#upgrading-to-v1880) for more information.

- Revert "Stop writing to column `user_id` of tables `profiles` and `user_filters`", which was introduced in Synapse 1.88.0rc1. ([\matrix-org#15953](matrix-org#15953))

- Add `not_user_type` param to the [list accounts admin API](https://matrix-org.github.io/synapse/v1.88/admin_api/user_admin_api.html#list-accounts). ([\matrix-org#15844](matrix-org#15844))

- Pin `pydantic` to `^=1.7.4` to avoid backwards-incompatible API changes from the 2.0.0 release.
  Contributed by @PaarthShah. ([\matrix-org#15862](matrix-org#15862))
- Correctly resize thumbnails with pillow version >=10. ([\matrix-org#15876](matrix-org#15876))

- Fixed header levels on the [Admin API "Users"](https://matrix-org.github.io/synapse/v1.87/admin_api/user_admin_api.html) documentation page. Contributed by @sumnerevans at @beeper. ([\matrix-org#15852](matrix-org#15852))
- Remove deprecated `worker_replication_host`, `worker_replication_http_port` and `worker_replication_http_tls` configuration options. ([\matrix-org#15872](matrix-org#15872))

- **Remove deprecated `worker_replication_host`, `worker_replication_http_port` and `worker_replication_http_tls` configuration options.** See the [upgrade notes](https://github.com/matrix-org/synapse/blob/release-v1.88/docs/upgrade.md#removal-of-worker_replication_-settings) for more details. ([\matrix-org#15860](matrix-org#15860))
- Remove support for Python 3.7 and hence for Debian Buster. ([\matrix-org#15851](matrix-org#15851), [\matrix-org#15892](matrix-org#15892), [\matrix-org#15893](matrix-org#15893), [\matrix-org#15917](matrix-org#15917))

- Add foreign key constraint to `event_forward_extremities`. ([\matrix-org#15751](matrix-org#15751), [\matrix-org#15907](matrix-org#15907))
- Add read/write style cross-worker locks. ([\matrix-org#15782](matrix-org#15782))
- Stop writing to column `user_id` of tables `profiles` and `user_filters`. ([\matrix-org#15787](matrix-org#15787))
- Use lower isolation level when cleaning old presence stream data to avoid serialization errors. ([\matrix-org#15826](matrix-org#15826))
- Add tracing to media `/upload` code paths. ([\matrix-org#15850](matrix-org#15850), [\matrix-org#15888](matrix-org#15888))
- Add a timeout that aborts any Postgres statement taking more than 1 hour. ([\matrix-org#15853](matrix-org#15853))
- Fix the `devenv up` configuration which was ignoring the config overrides. ([\matrix-org#15854](matrix-org#15854))
- Optimised cleanup of old entries in `device_lists_stream`. ([\matrix-org#15861](matrix-org#15861))
- Update the Matrix clients link in the _It works! Synapse is running_ landing page. ([\matrix-org#15874](matrix-org#15874))
- Fix building Synapse with the nightly Rust compiler. ([\matrix-org#15906](matrix-org#15906))
- Add `Server` to Access-Control-Expose-Headers header. ([\matrix-org#15908](matrix-org#15908))
