Allow non-member state sent in room batch to resolve for historic events. /batch_send state_events_at_start

Previously, non-member state didn't resolve because filter_events_for_client filters out all outlier state except for out-of-band membership.

Part of #12110

Complement test: matrix-org/complement#354

Part of MSC2716

Removing these as outliers because filter_events_for_client filters out all outlier state except for out-of-band membership. And we want all of the state_events_at_start to resolve when a historical event is pulled.

This state chain is still disconnected from the normal DAG because the first event has empty prev_events so they state just floats in a chain of its own.

I'm struggling to understand how the diagram relates to the change here. Which of the events on the diagram correspond to this code path?

Just giving it as a reference. It shows that the state chain floats by no prev_events and that the state chain is disconnected from the historical message chain (no prev_event edges connect them).

ok, so this code is handling the events in the yellow boxes labelled batch0, batch1, batch2 ?

persist_state_events_at_start is handling the state events above the yellow boxes (m.room.member events in the diagram). The historical state chain.

The yellow boxes are the historical messages chains

well in that case, this seems wrong. those events seem to be random state events where we haven't wired them up to the event dag? why would we have the state at those events?

Either I'm severely understanding your diagram, or something is odd here.

Correct, they float in their own chain.

why would we have the state at those events?

But we technically do have the state for them because we're manually providing it via state_event_ids

generally not setting these things as outliers seem sensible, but I'm not quite following the justification.

Fundamentally, we have the state at these events so they shouldn't be marked as outliers, so this seems correct.

This is a great point too! Wasn't thinking in that context.

Synapse 1.57.0 (2022-04-19)
===========================

This version includes a [change](matrix-org/synapse#12209) to the way transaction IDs are managed for application services. If your deployment uses a dedicated worker for application service traffic, **it must be stopped** when the database is upgraded (which normally happens when the main process is upgraded), to ensure the change is made safely without any risk of reusing transaction IDs.

See the [upgrade notes](https://github.com/matrix-org/synapse/blob/v1.57.0rc1/docs/upgrade.md#upgrading-to-v1570) for more details.

No significant changes since 1.57.0rc1.

Synapse 1.57.0rc1 (2022-04-12)
==============================

Features
--------

- Send device list changes to application services as specified by [MSC3202](matrix-org/matrix-spec-proposals#3202), using unstable prefixes. The `msc3202_transaction_extensions` experimental homeserver config option must be enabled and `org.matrix.msc3202: true` must be present in the application service registration file for device list changes to be sent. The "left" field is currently always empty. ([\#11881](matrix-org/synapse#11881))
- Optimise fetching large quantities of missing room state over federation. ([\#12040](matrix-org/synapse#12040))
- Offload the `update_client_ip` background job from the main process to the background worker, when using Redis-based replication. ([\#12251](matrix-org/synapse#12251))
- Move `update_client_ip` background job from the main process to the background worker. ([\#12252](matrix-org/synapse#12252))
- Add a module callback to react to new 3PID (email address, phone number) associations. ([\#12302](matrix-org/synapse#12302))
- Add a configuration option to remove a specific set of rooms from sync responses. ([\#12310](matrix-org/synapse#12310))
- Add a module callback to react to account data changes. ([\#12327](matrix-org/synapse#12327))
- Allow setting user admin status using the module API. Contributed by Famedly. ([\#12341](matrix-org/synapse#12341))
- Reduce overhead of restarting synchrotrons. ([\#12367](matrix-org/synapse#12367), [\#12372](matrix-org/synapse#12372))
- Update `/messages` to use historic pagination tokens if no `from` query parameter is given. ([\#12370](matrix-org/synapse#12370))
- Add a module API for reading and writing global account data. ([\#12391](matrix-org/synapse#12391))
- Support the stable `v1` endpoint for `/relations`, per [MSC2675](matrix-org/matrix-spec-proposals#2675). ([\#12403](matrix-org/synapse#12403))
- Include bundled aggregations in search results
  ([MSC3666](matrix-org/matrix-spec-proposals#3666)). ([\#12436](matrix-org/synapse#12436))

Bugfixes
--------

- Fix a long-standing bug where updates to the server notices user profile (display name/avatar URL) in the configuration would not be applied to pre-existing rooms. Contributed by Jorge Florian. ([\#12115](matrix-org/synapse#12115))
- Fix a long-standing bug where events from ignored users were still considered for bundled aggregations. ([\#12235](matrix-org/synapse#12235), [\#12338](matrix-org/synapse#12338))
- Fix non-member state events not resolving for historical events when used in [MSC2716](matrix-org/matrix-spec-proposals#2716) `/batch_send` `state_events_at_start`. ([\#12329](matrix-org/synapse#12329))
- Fix a long-standing bug affecting URL previews that would generate a 500 response instead of a 403 if the previewed URL includes a port that isn't allowed by the relevant blacklist. ([\#12333](matrix-org/synapse#12333))
- Default to `private` room visibility rather than `public` when a client does not specify one, according to spec. ([\#12350](matrix-org/synapse#12350))
- Fix a spec compliance issue where requests to the `/publicRooms` federation API would specify `limit` as a string. ([\#12364](matrix-org/synapse#12364), [\#12410](matrix-org/synapse#12410))
- Fix a bug introduced in Synapse 1.49.0 which caused the `synapse_event_persisted_position` metric to have invalid values. ([\#12390](matrix-org/synapse#12390))

Updates to the Docker image
---------------------------

- Bundle locked versions of dependencies into the Docker image. ([\#12385](matrix-org/synapse#12385), [\#12439](matrix-org/synapse#12439))
- Fix up healthcheck generation for workers docker image. ([\#12405](matrix-org/synapse#12405))

- Upgrade the version of `mdbook` in CI to 0.4.17. ([\#12339](matrix-org/synapse#12339))
- Updates to the Room DAG concepts development document to clarify that we mark events as outliers because we don't have any state for them. ([\#12345](matrix-org/synapse#12345))
- Update the link to Redis pub/sub documentation in the workers documentation. ([\#12369](matrix-org/synapse#12369))
- Remove documentation for converting a legacy structured logging configuration to the new format. ([\#12392](matrix-org/synapse#12392))

Deprecations and Removals
-------------------------

- Remove the unused and unstable `/aggregations` endpoint which was removed from [MSC2675](matrix-org/matrix-spec-proposals#2675). ([\#12293](matrix-org/synapse#12293))

Internal Changes
----------------

- Remove lingering unstable references to MSC2403 (knocking). ([\#12165](matrix-org/synapse#12165))

- Omit sending "offline" presence updates to application services after they are initially configured. ([\#12193](matrix-org/synapse#12193))
- Switch to using a sequence to generate AS transaction IDs. Contributed by Nick @ Beeper. If running synapse with a dedicated appservice worker, this MUST be stopped before upgrading the main process and database. ([\#12209](matrix-org/synapse#12209))
- Add missing type hints for storage. ([\#12267](matrix-org/synapse#12267))

- Fix typechecker problems exposed by signedjson 1.1.2. ([\#12326](matrix-org/synapse#12326))
- Remove the `tox` packaging job: it will be redundant once #11537 lands. ([\#12334](matrix-org/synapse#12334))
- Ignore `.envrc` for `direnv` users. ([\#12335](matrix-org/synapse#12335))
- Remove the (broadly unused, dev-only) dockerfile for pg tests. ([\#12336](matrix-org/synapse#12336))
- Remove redundant `get_success` calls in test code. ([\#12346](matrix-org/synapse#12346))

- Make `StreamToken.from_string` and `RoomStreamToken.parse` propagate cancellations instead of replacing them with `SynapseError`s. ([\#12366](matrix-org/synapse#12366))
- Add type hints to tests files. ([\#12371](matrix-org/synapse#12371))
- Allow specifying the Postgres database's port when running unit tests with Postgres. ([\#12376](matrix-org/synapse#12376))
- Remove temporary pin of signedjson<=1.1.1 that was added in Synapse 1.56.0. ([\#12379](matrix-org/synapse#12379))
- Add opentracing spans to calls to external cache. ([\#12380](matrix-org/synapse#12380))
- Lay groundwork for using `poetry` to manage Synapse's dependencies. ([\#12381](matrix-org/synapse#12381), [\#12407](matrix-org/synapse#12407), [\#12412](matrix-org/synapse#12412), [\#12418](matrix-org/synapse#12418))

- Update docstrings for `ReadWriteLock` tests. ([\matrix-org#12354](matrix-org#12354))
- Refactor `Linearizer`, convert methods to async and use an async context manager. ([\matrix-org#12357](matrix-org#12357))
- Fix a long-standing bug where `Linearizer`s could get stuck if a cancellation were to happen at the wrong time. ([\matrix-org#12358](matrix-org#12358))
- Make `StreamToken.from_string` and `RoomStreamToken.parse` propagate cancellations instead of replacing them with `SynapseError`s. ([\matrix-org#12366](matrix-org#12366))
- Add type hints to tests files. ([\matrix-org#12371](matrix-org#12371))
- Allow specifying the Postgres database's port when running unit tests with Postgres. ([\matrix-org#12376](matrix-org#12376))
- Remove temporary pin of signedjson<=1.1.1 that was added in Synapse 1.56.0. ([\matrix-org#12379](matrix-org#12379))
- Add opentracing spans to calls to external cache. ([\matrix-org#12380](matrix-org#12380))
- Lay groundwork for using `poetry` to manage Synapse's dependencies. ([\matrix-org#12381](matrix-org#12381), [\matrix-org#12407](matrix-org#12407), [\matrix-org#12412](matrix-org#12412), [\matrix-org#12418](matrix-org#12418))
