Add `event.internal_metadata.instance_name` (the worker instance that persisted the event) to go alongside the existing `event.internal_metadata.stream_ordering`.
`instance_name` is useful to properly compare and query for events with a token since you need to compare both the `stream_ordering` and `instance_name` against the vector clock/`instance_map` in the `RoomStreamToken`.
This is pre-requisite work and may be used in https://github.com/element-hq/synapse/pull/17293
Adding `event.internal_metadata.instance_name` was first mentioned in the initial Sliding Sync PR while pairing with @erikjohnston, see 09609cb0db (diff-5cd773fb307aa754bd3948871ba118b1ef0303f4d72d42a2d21e38242bf4e096R405-R410)
During the migration the automated script to update the copyright
headers accidentally got rid of some of the existing copyright lines.
Reinstate them.
For now this maintains compatible with old Synapses by falling back
to using transaction semantics on a per-access token. A future version
of Synapse will drop support for this.
The location of the redacts field changes in room version 11. Ensure
it is copied to the *new* location for *old* room versions for
forwards-compatibility with clients.
Note that copying it to the *old* location for the *new* room version
was previously handled.
And fix a bug in the implementation of the updated redaction
format (MSC2174) where the top-level redacts field was not
properly added for backwards-compatibility.
The event_fields property in filters should use the proper
escape rules, namely backslashes can be escaped with
an additional backslash.
This adds tests (adapted from matrix-js-sdk) and implements
the logic to properly split the event_fields strings.
MSC3389 proposes protecting the relation type & parent event ID
from redaction. This keeps the relation information intact after
redaction which helps with some UX flaws (e.g. deleting an
event causes it to no longer be in a thread, which is confusing).
Additionally:
* Consistently use `freeze()` in test

Enables MSC3925 support by default, which:
* Includes the full edit event in the bundled aggregations of an
edited event.
* Stops modifying the original event's content to return the new
content from the edit event.
This is a backwards-incompatible change that is considered to be
"correct" by the spec.
It turns out that no clients rely on server-side aggregation of `m.annotation`
relationships: it's just not very useful as currently implemented.
It's also non-trivial to calculate.
I want to remove it from MSC2677, so to keep the implementation in line, let's
remove it here.
* Better test for bad values in power levels events
The previous test only checked that Synapse didn't raise an exception,
but didn't check that we had correctly interpreted the value of the
dodgy power level.
It also conflated two things: bad room notification levels, and bad user
levels. There _is_ logic for converting the latter to integers, but we
should test it separately.
* Check we ignore types that don't convert to int
* Handle `None` values in `notifications.room`
* Changelog
* Also test that bad values are rejected by event auth
* Docstring
* linter scripttttttttt
* Test boolean values in PL content
* Reject boolean power levels
* Changelog
Two parts to this:
* Bundle the whole of the replacement with any edited events. This is backwards-compatible so I haven't put it behind a flag.
* Optionally, inhibit server-side replacement of edited events. This has scope to break things, so it is currently disabled by default.
* Declare new config
* Parse new config
* Read new config
* Don't use trial/our TestCase where it's not needed

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.

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).
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.
The unstable identifiers are still supported if the experimental configuration
flag is enabled. The unstable identifiers will be removed in a future release.
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).
This makes the serialization of events synchronous (and it no
longer access the database), but we must manually calculate and
provide the bundled aggregations.
Overall this should cause no change in behavior, but is prep work
for other improvements.
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.
