Avoid an n+1 query problem and fetch the bundled aggregations for
m.annotation relations in a single query instead of a query per event.
This applies similar logic for as was previously done for edits in
8b309adb43 (#11660) and threads
in b65acead42 (#11752).
When the last event in a thread is redacted we need to update
the threads table:
* Find the new latest event in the thread and store it into the table; or
* Remove the thread from the table if it is no longer a thread (i.e. all
events in the thread were redacted).
Stabilize the threads API (MSC3856) by supporting (only) the v1
path for the endpoint.
This also marks the API as safe for workers since it is a read-only
API.
Implement the /threads endpoint from MSC3856.
This is currently unstable and behind an experimental configuration
flag.
It includes a background update to backfill data, results from
the /threads endpoint will be partial until that finishes.
Keep the old behavior (of including the original_event field) for any
requests to the /unstable version of the endpoint, but do not include
the field when the /v1 version is used.
This should avoid new clients from depending on this field, but will
not help with current dependencies.
Since MSC3715 has passed FCP, the stable parameter can be used.
This currently falls back to the unstable parameter if the stable
parameter is not provided (and MSC3715 support is enabled in
the configuration).
This fixes a bug where the `/relations` API with `dir=f` would
skip the first item of each page (except the first page), causing
incomplete data to be returned to the client.
Fixes a regression from 8b309adb43 (#11660)
and b65acead42 (#11752) where events which
themselves were an edit or an annotation could have bundled aggregations calculated,
which is not allowed.
The `latest_event` field of the bundled aggregations for `m.thread` relations
did not include bundled aggregations itself. This resulted in clients needing to
immediately request the event from the server (and thus making it useless that
the latest event itself was serialized instead of just including an event ID).
Consider the requester's ignored users when calculating the
bundled aggregations.
See #12285 / 4df10d3214
for corresponding changes for the `/relations` endpoint.
This endpoint was removed from MSC2675 before it was approved.
It is currently unspecified (even in any MSCs) and therefore subject to
removal. It is not implemented by any known clients.
This also changes the bundled aggregation format for `m.annotation`,
which previously included pagination tokens for the `/aggregations`
endpoint, which are no longer useful.
We fetch the thread summary in two phases:
1. The summary that is shared by all users (count of messages and latest event).
2. Whether the requesting user has participated in the thread.
There's no use in attempting step 2 for events which did not return a summary
from step 1.
An error occured if a filter was supplied with `event_fields` which did not include
`unsigned`.
In that case, bundled aggregations are still added as the spec states it is allowed
for servers to add additional fields.
* Moves the relation pagination tests to a separate class.
* Move the assertion of the response code into the `_send_relation` helper.
* Moves some helpers into the base-class.
The unstable identifiers are still supported if the experimental configuration
flag is enabled. The unstable identifiers will be removed in a future release.
This is allowed per MSC2675, although the original implementation did
not allow for it and would return an empty chunk / not bundle aggregations.
The main thing to improve is that the various caches get cleared properly
when an event is redacted, and that edits must not leak if the original
event is redacted (as that would presumably leak something similar to
the original event content).
* Add type hints to `tests/rest/client`
* newsfile
* fix imports
* add `test_account.py`
* Remove one type hint in `test_report_event.py`
* change `on_create_room` to `async`
* update new functions in `test_third_party_rules.py`
* Add `test_filter.py`
* add `test_rooms.py`
* change to `assertEquals` to `assertEqual`
* lint
If the latest event in a thread was edited than the original
event content was included in bundled aggregation for
threads instead of the edited event content.
This is some odds and ends found during the review of #11791
and while continuing to work in this code:
* Return attrs classes instead of dictionaries from some methods
to improve type safety.
* Call `get_bundled_aggregations` fewer times.
* Adds a missing assertion in the tests.
* Do not return empty bundled aggregations for an event (preferring
to not include the bundle at all, as the docstring states).
* Disable aggregation bundling on `/sync` responses
A partial revert of #11478. This turns out to have had a significant CPU impact
on initial-sync handling. For now, let's disable it, until we find a more
efficient way of achieving this.
* Fix tests.

Due to updates to MSC2675 this includes a few fixes:
* Include bundled aggregations for /sync.
* Do not include bundled aggregations for /initialSync and /events.
* Do not bundle aggregations for state events.
* Clarifies comments and variable names.
