Trace how many new events from the backfill response we need to process (#15633)
You can kinda derive this information from how many `_process_pulled_event` spans there are but it would be nice to quickly glance.

Handle missing previous read marker event. (#15464)
If the previous read marker is pointing to an event that no longer exists
(e.g. due to retention) then assume that the newly given read marker

Error if attempting to set m.push_rules account data, per MSC4010. (#15555)
m.push_rules, like m.fully_read, is a special account data type that cannot
be set using the normal /account_data endpoint. Return an error instead
of allowing data that will not be used to be stored.

Check appservices for devices during a /user/devices query. (#15539)
MSC3984 proxies /keys/query requests to appservices, but servers will
can also requests devices / keys from the /user/devices endpoint.

The formats are close enough that we can "proxy" that /user/devices to
appservices (by calling /keys/query) and then change the format of the
returned data before returning it over federation.

Factor out an is_mine_server_name method (#15542)
Add an `is_mine_server_name` method, similar to `is_mine_id`.

Ideally we would use this consistently, instead of sometimes comparing
against `hs.hostname` and other times reaching into
`hs.config.server.server_name`.

Also fix a bug in the tests where `hs.hostname` would sometimes differ
from `hs.config.server.server_name`.

Initial implementation of MSC3981: recursive relations API (#15315)
Adds an optional keyword argument to the /relations API which
will recurse a limited number of event relationships.

This will cause the API to return not just the events related to the
parent event, but also events related to those related to the parent
event, etc.

This is disabled by default behind an experimental configuration
flag and is currently implemented using prefixed parameters.

Add unstable /keys/claim endpoint which always returns fallback keys. (#15462)
It can be useful to always return the fallback key when attempting to
claim keys. This adds an unstable endpoint for `/keys/claim` which
always returns fallback keys in addition to one-time-keys.

The fallback key(s) are not marked as "used" unless there are no
corresponding OTKs.

This is currently defined in MSC3983 (although likely to be split out
to a separate MSC). The endpoint shape may change or be requested
differently (i.e. a keyword parameter on the current endpoint), but the
core logic should be reasonable.

Fix a rare bug where initial /syncs would fail (#15383)
This change fixes a rare bug where initial /syncs would fail with a
`KeyError` under the following circumstances:
 1. A user fast joins a remote room.
 2. The user is kicked from the room before the room's full state has
    been synced.
 3. A second local user fast joins the room.
 4. Events are backfilled into the room with a higher topological
    ordering than the original user's leave. They are assigned a
    negative stream ordering. It's not clear how backfill happened here,
    since it is expected to be equivalent to syncing the full state.
 5. The second local user leaves the room before the room's full state
    has been synced. The homeserver does not complete the sync.
 6. The original user performs an initial /sync with lazy_load_members
    enabled.
     * Because they were kicked from the room, the room is included in
       the /sync response even though the include_leave option is not
       specified.
     * To populate the room's timeline, `_load_filtered_recents` /
       `get_recent_events_for_room` fetches events with a lower stream
       ordering than the leave event and picks the ones with the highest
       topological orderings (which are most recent). This captures the
       backfilled events after the leave, since they have a negative
       stream ordering. These events are filtered out of the timeline,
       since the user was not in the room at the time and cannot view
       them. The sync code ends up with an empty timeline for the room
       that notably does not include the user's leave event.
       This seems buggy, but at least we don't disclose events the user
       isn't allowed to see.
     * Normally, `compute_state_delta` would fetch the state at the
       start and end of the room's timeline to generate the sync
       response. Since the timeline is empty, it fetches the state at
       `min(now, last event in the room)`, which corresponds with the
       second user's leave. The state during the entirety of the second
       user's membership does not include the membership for the first
       user because of partial state.
       This part is also questionable, since we are fetching state from
       outside the bounds of the user's membership.
     * `compute_state_delta` then tries and fails to find the user's
       membership in the auth events of timeline events. Because there
       is no timeline event whose auth events are expected to contain
       the user's membership, a `KeyError` is raised.

Also contains a drive-by fix for a separate unlikely race condition.

This should help reduce the number of devices e.g. simple bots the repeatedly login rack up.

Fix joining rooms you have been unbanned from (#15323)
* Fix joining rooms you have been unbanned from

Since forever synapse did not allow you to join a room after you have
been unbanned from it over federation. This was not actually because of
the unban event not federating. Synapse simply used outdated state to
validate the join transition. This skips the validation if we are not in
the room and for that reason won't have the current room state.

Fixes #1563

Make cleaning up pushers depend on the device_id instead of the token_id (#15280)
This makes it so that we rely on the `device_id` to delete pushers on logout,
instead of relying on the `access_token_id`. This ensures we're not removing
pushers on token refresh, and prepares for a world without access token IDs
(also known as the OIDC).

This actually runs the `set_device_id_for_pushers` background update, which
was forgotten in #13831.

Note that for backwards compatibility it still deletes pushers based on the
`access_token` until the background update finishes.

Faster joins: Fix spurious errors on incremental sync (#15232)
When pushing events in partial state rooms down incremental /sync, we
try to find the `m.room.member` state event for their senders by digging
through their auth events, so that we can present the membership to the
client. Events usually have a membership event in their auth events,
with the exception of the `m.room.create` event and a user's first join
into the room.

When implementing #13477, we took the case of a user's first join into
account, but forgot to handle the `m.room.create` case. This change
fixes that.

Mitigate a race where /make_join could 403 for restricted rooms (#15080)
Previously, when creating a join event in /make_join, we would decide
whether to include additional fields to satisfy restricted room checks
based on the current state of the room. Then, when building the event,
we would capture the forward extremities of the room to use as prev
events.

This is subject to race conditions. For example, when leaving and
rejoining a room, the following sequence of events leads to a misleading
403 response:
1. /make_join reads the current state of the room and sees that the user
   is still in the room. It decides to omit the field required for
   restricted room joins.
2. The leave event is persisted and the room's forward extremities are
   updated.
3. /make_join builds the event, using the post-leave forward extremities.
   The event then fails the restricted room checks.

To mitigate the race, we move the read of the forward extremities closer
to the read of the current state. Ideally, we would compute the state
based off the chosen prev events, but that can involve state resolution,
which is expensive.

* Tweak DBAPI2 Protocol to be accepted by mypy 1.0

Some extra context in:
- https://github.com/matrix-org/python-canonicaljson/pull/57
- https://github.com/python/mypy/issues/6002
- https://mypy.readthedocs.io/en/latest/common_issues.html#covariant-subtyping-of-mutable-protocol-members-is-rejected

* Pull in updated canonicaljson lib

so the protocol check just works

* Improve comments in opentracing

I tried to workaround the ignores but found it too much trouble.

I think the corresponding issue is
https://github.com/python/mypy/issues/12909. The mypy repo has a PR
claiming to fix this (https://github.com/python/mypy/pull/14677) which
might mean this gets resolved soon?

* Better annotation for INTERACTIVE_AUTH_CHECKERS

* Drive-by AUTH_TYPE annotation, to remove an ignore

Fix order of partial state tables when purging (#15068)
* Fix order of partial state tables when purging

`partial_state_rooms` has an FK on `events` pointing to the join event we
get from `/send_join`, so we must delete from that table before deleting
from `events`.

**NB:** It would be nice to cancel any resync processes for the room
being purged. We do not do this at present. To do so reliably we'd need
an internal HTTP "replication" endpoint, because the worker doing the
resync process may be different to that handling the purge request.

The first time the resync process tries to write data after the deletion
it will fail because we have deleted necessary data e.g. auth
events. AFAICS it will not retry the resync, so the only downside to
not cancelling the resync is a scary-looking traceback.

(This is presumably extremely race-sensitive.)

* Changelog

* admist(?) -> between

Faster joins: Omit device list updates from partial state rooms in /sync (#15069)
...when lazy loading of members is not enabled. It's weird to notify
a client that another user's device list has changed when the client
doesn't think that they share a room.

Note that when a room is un-partial stated, device list updates are
emitted for every member in that room over /sync.

Return read-only collections from @cached methods (#13755)

the given room is no longer partial stated, to explicitly indicate when
the room has partial state. Otherwise it's not clear whether an empty

but the server we joined off told us that there are no servers in the

a specific user and a specific sync. This rename helps to clarify the
distinction between the global config and the rooms to exclude for a
specific sync.

* Track a list of excluded rooms on SyncResultBuilder

given sync period.

* Fix mutation of `@cached` return value

This was fouling up a complement test added alongside this PR.
Excluding a room would mean the set of forgotten rooms in the cache
would be extended. This means that room could be erroneously considered
forgotten in the future.

Introduced in #12310, Synapse 1.57.0. I don't think this had any
user-visible side effects (until now).

Similar plan as before. We've omitted rooms from certain sync responses;
now we establish the mechanism to reintroduce them into future syncs.

* Force un-partial-stated rooms to be newly-joined

for eager incremental syncs only, provided they're still fully stated

Faster joins: Update room stats and the user directory on workers when finishing join (#14874)
* Faster joins: Update room stats and user directory on workers when done

When finishing a partial state join to a room, we update the current
state of the room without persisting additional events. Workers receive
notice of the current state update over replication, but neglect to wake
the room stats and user directory updaters, which then get incidentally
triggered the next time an event is persisted or an unrelated event
persister sends out a stream position update.

We wake the room stats and user directory updaters at the appropriate
time in this commit.

Faster joins: Fix incompatibility with restricted joins (#14882)

When joining a restricted room where the local homeserver does not have
a user able to issue invites, we perform a second remote join. We want
to avoid clearing out forward extremities in this case because the
forward extremities we have are up to date and clearing out forward
extremities creates a window in which the room can get bricked if
Synapse crashes.

Faster joins: Avoid starting duplicate partial state syncs (#14844)
Currently, we will try to start a new partial state sync every time we
perform a remote join, which is undesirable if there is already one
running for a given room.

We intend to perform remote joins whenever additional local users wish
to join a partial state room, so let's ensure that we do not start more
than one concurrent partial state sync for any given room.

------------------------------------------------------------------------

There is a race condition where the homeserver leaves a room and later
rejoins while the partial state sync from the previous membership is
still running. There is no guarantee that the previous partial state
sync will process the latest join, so we restart it if needed.

This has two related changes:

* It enables fast-path processing for an empty filter (`[]`) which was

* It special cases a `/sync` filter with no-rooms to skip all room
  processing, previously we would partially skip processing, but would
  generally still calculate intermediate values for each room which were
  then unused.

Future changes might consider further optimizations:

* Skip calculating per-room account data when all rooms are filtered (currently

Use the room type from stats in hierarchy response. (#14263)
This avoids pulling additional state information (and events) from
the database for each item returned in the hierarchy response.

The room type might be out of date until a background update finishes
running, the worst impact of this would be spaces being treated as rooms
in the hierarchy response. This should self-heal once the background
update finishes.

Allow selecting "prejoin" events by state keys (#14642)
* Declare new config

* Parse new config

* Read new config

* Don't use trial/our TestCase where it's not needed

Before:

```
$ time trial tests/events/test_utils.py > /dev/null

real	0m2.277s
user	0m2.186s
sys	0m0.083s
```

After:
```
$ time trial tests/events/test_utils.py > /dev/null

real	0m0.566s
user	0m0.508s
sys	0m0.056s
```

* Helper to upsert to event fields

without exceeding size limits.

* Use helper when adding invite/knock state

Now that we allow admins to include events in prejoin room state with
arbitrary state keys, be a good Matrix citizen and ensure they don't
accidentally create an oversized event.

* Changelog

* Move StateFilter tests

should have done this in #14668

* Add extra methods to StateFilter

* Use StateFilter

* Ensure test file enforces typed defs; alphabetise

* Workaround surprising get_current_state_ids

Improve logging and opentracing for to-device message handling (#14598)
A batch of changes intended to make it easier to trace to-device messages through the system.

The intention here is that a client can set a property org.matrix.msgid in any to-device message it sends. That ID is then included in any tracing or logging related to the message. (Suggestions as to where this field should be documented welcome. I'm not enthusiastic about speccing it - it's very much an optional extra to help with debugging.)

I've also generally improved the data we send to opentracing for these messages.

Include thread information when sending receipts over federation. (#14466)
Include the thread_id field when sending read receipts over
federation. This might result in the same user having multiple
read receipts per-room, meaning multiple EDUs must be sent
to encapsulate those receipts.

This restructures the PerDestinationQueue APIs to support
multiple receipt EDUs, queue_read_receipt now becomes linear
time in the number of queued threaded receipts in the room for
the given user, it is expected this is a small number since receipt
EDUs are sent as filler in transactions.

Track unconverted device list outbound pokes using a position instead (#14516)
When a local device list change is added to
`device_lists_changes_in_room`, the `converted_to_destinations` flag is
set to `FALSE` and the `_handle_new_device_update_async` background
process is started. This background process looks for unconverted rows
in `device_lists_changes_in_room`, copies them to
`device_lists_outbound_pokes` and updates the flag.

To update the `converted_to_destinations` flag, the database performs a
`DELETE` and `INSERT` internally, which fragments the table. To avoid
this, track unconverted rows using a `(stream ID, room ID)` position
instead of the flag.

From now on, the `converted_to_destinations` column indicates rows that
need converting to outbound pokes, but does not indicate whether the
conversion has already taken place.

Closes #14037.

Stop getting missing prev_events after we already know their signature is 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 summarization code is also updated to be per thread, instead of per
room.

Do not return unspecced original_event field when using the stable /relations endpoint. (#14025)
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.

should accept a ts parameter for appservices. This change expands support
to /state and adds tests.

Fix get_users_in_room mis-use in transfer_room_state_on_room_upgrade (#13960)
Spawning from looking into `get_users_in_room` while investigating https://github.com/matrix-org/synapse/issues/13942#issuecomment-1262787050.

Clarifications in user directory for users who share rooms tracking (#13966)
Spawned while working on [`get_users_in_room` mis-uses](https://github.com/matrix-org/synapse/pull/13958#discussion_r984074897) and thinking we could use `get_local_users_in_room` here but we can't.

From first glance, it seemed like this was only using local users from all of the `is_mine_id(user_id)` checks but I see that it does actually use remote users. Just making things a little more clear here what it does and mentions remote users so maybe that will be more obvious in the future.

Fix performance regression in get_users_in_room (#13972)
Fixes #13942. Introduced in #13575.

Basically, let's only get the ordered set of hosts out of the DB if we need an ordered set of hosts. Since we split the function up the caching won't be as good, but I think it will still be fine as e.g. multiple backfill requests for the same room will hit the cache.

Handle local device list updates during partial join (#13934) 2022-09-28 23:22:35 +01:00

Limit and filter the number of backfill points to get from the database (#13879)
There is no need to grab thousands of backfill points when we only need 5 to make the `/backfill` request with. We need to grab a few extra in case the first few aren't visible in the history.

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)
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.

Prepatory work for batching events to send (#13487)
This PR begins work on batching up events during the creation of a room. The PR splits out the creation and sending/persisting of the events. The first three events in the creation of the room-creating the room, joining the creator to the room, and the power levels event are sent sequentially, while the subsequent events are created and collected to be sent at the end of the function. This is currently done by appending them to a list and then iterating over the list to send, the next step (after this PR) would be to send and persist the collected events as a batch.

Faster room joins: Fix spurious error when joining a room (#13872)
During a `lazy_load_members` `/sync`, we look through auth events in
rooms with partial state to find prior membership events. When such a
membership is not found, an error is logged.

Since the first join event for a user never has a prior membership event
to cite, the error would always be logged when one appeared in the room
timeline.

Avoid logging errors for such events.

Introduced in #13477.

Send device list updates out to servers in partially joined rooms (#13874)
Use the provided list of servers in the room from the `/send_join`
response, since we will not know which users are in the room.  This
isn't sufficient to ensure that all remote servers receive the right
device list updates, since the `/send_join` response may be inaccurate
or we may calculate the membership state of new users in the room
incorrectly.
