==============================
Synapse 1.59 makes several changes that server administrators should be aware of:
- Device name lookup over federation is now disabled by default. ([\#12616](https://github.com/matrix-org/synapse/issues/12616))
- The `synapse.app.appservice` and `synapse.app.user_dir` worker application types are now deprecated. ([\#12452](https://github.com/matrix-org/synapse/issues/12452), [\#12654](https://github.com/matrix-org/synapse/issues/12654))
See [the upgrade notes](https://github.com/matrix-org/synapse/blob/develop/docs/upgrade.md#upgrading-to-v1590) for more details.
Additionally, this release removes the non-standard `m.login.jwt` login type from Synapse. It can be replaced with `org.matrix.login.jwt` for identical behaviour. This is only used if `jwt_config.enabled` is set to `true` in the configuration. ([\#12597](https://github.com/matrix-org/synapse/issues/12597))
Bugfixes
--------
- Fix a bug introduced in Synapse 1.58.0 where `/sync` would fail if the most recent event in a room was rejected. ([\#12729](https://github.com/matrix-org/synapse/issues/12729))

Synapse 1.59.0rc2 (2022-05-16)
==============================
Synapse 1.59 makes several changes that server administrators should be aware of:
- Device name lookup over federation is now disabled by default. ([\#12616](https://github.com/matrix-org/synapse/issues/12616))
- The `synapse.app.appservice` and `synapse.app.user_dir` worker application types are now deprecated. ([\#12452](https://github.com/matrix-org/synapse/issues/12452), [\#12654](https://github.com/matrix-org/synapse/issues/12654))
See [the upgrade notes](https://github.com/matrix-org/synapse/blob/develop/docs/upgrade.md#upgrading-to-v1590) for more details.
Additionally, this release removes the non-standard `m.login.jwt` login type from Synapse. It can be replaced with `org.matrix.login.jwt` for identical behaviour. This is only used if `jwt_config.enabled` is set to `true` in the configuration. ([\#12597](https://github.com/matrix-org/synapse/issues/12597))
Bugfixes
--------
- Fix a bug introduced in Synapse 1.58.0 where `/sync` would fail if the most recent event in a room was rejected. ([\#12729](https://github.com/matrix-org/synapse/issues/12729))
Parse the `m.relates_to` event content field (which describes relations)
in a single place, this is used during:
* Event persistence.
* Validation of the Client-Server API.
* Fetching bundled aggregations.
* Processing of push rules.
Each of these separately implement the logic and each made slightly
different assumptions about what was valid. Some had minor / potential
bugs.
Refactor how the `EventContext` class works, with the intention of reducing the amount of state we fetch from the DB during event processing.
The idea here is to get rid of the cached `current_state_ids` and `prev_state_ids` that live in the `EventContext`, and instead defer straight to the database (and its caching).
One change that may have a noticeable effect is that we now no longer prefill the `get_current_state_ids` cache on a state change. However, that query is relatively light, since its just a case of reading a table from the DB (unlike fetching state at an event which is more heavyweight). For deployments with workers this cache isn't even used.
Part of #12684
* Add mau_appservice_trial_days
* Add a test
* Tweaks
* changelog
* Ensure we sync after the delay
* Fix types
* Add config statement
* Fix test
* Reinstate logging that got removed
* Fix feature name
* Changes hidden read receipts to be a separate receipt type
(instead of a field on `m.read`).
* Updates the `/receipts` endpoint to accept `m.fully_read`.
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).
I've seen a few errors which can only plausibly be explained by the calculated
event id for an event being different from the ID of the event in the
database. It should be cheap to check this, so let's do so and raise an
exception.
This works by taking a row level lock on the `rooms` table at the start of both transactions, ensuring that they don't run at the same time. In the event persistence transaction we also check that there is an entry still in the `rooms` table.
I can't figure out how to do this in SQLite. I was just going to lock the table, but it seems that we don't support that in SQLite either, so I'm *really* confused as to how we maintain integrity in SQLite when using `lock_table`....
Over time we've begun to use newer versions of mypy, typeshed, stub
packages---and of course we've improved our own annotations. This makes
some type ignore comments no longer necessary. I have removed them.
There was one exception: a module that imports `select.epoll`. The
ignore is redundant on Linux, but I've kept it ignored for those of us
who work on the source tree using not-Linux. (#11771)
I'm more interested in the config line which enforces this. I want
unused ignores to be reported, because I think it's useful feedback when
annotating to know when you've fixed a problem you had to previously
ignore.
* Installing extras before typechecking
Lacking an easy way to install all extras generically, let's bite the bullet and
make install the hand-maintained `all` extra before typechecking.
Now that https://github.com/matrix-org/backend-meta/pull/6 is merged to
the release/v1 branch.
Try to avoid an OOM by checking fewer extremities.
Generally this is a big rewrite of _maybe_backfill, to try and fix some of the TODOs and other problems in it. It's best reviewed commit-by-commit.
Multiple calls to `EventsWorkerStore._get_events_from_cache_or_db` can
reuse the same database fetch, which is initiated by the first call.
Ensure that cancelling the first call doesn't cancel the other calls
sharing the same database fetch.

This will mainly be useful when dealing with module callbacks, which are
all typed as returning `Awaitable`s instead of coroutines or
`Deferred`s.

When we join a room via the faster-joins mechanism, we end up with "partial
state" at some points on the event DAG. Many parts of the codebase need to
wait for the full state to load. So, we implement a mechanism to keep track of
which events have partial state, and wait for them to be fully-populated.
We work through all the events with partial state, updating the state at each
of them. Once it's done, we recalculate the state for the whole room, and then
mark the room as having complete state.
* Add some type hints to datastore
* newsfile
* change `Collection` to `List`
* refactor return type of `select_users_txn`
* correct type hint in `stream.py`
* Remove `Optional` in `select_users_txn`
* remove not needed return type in `__init__`
* Revert change in `get_stream_id_for_event_txn`
* Remove import from `Literal`
Consider the requester's ignored users when calculating the
bundled aggregations.
See #12285 / 4df10d3214
for corresponding changes for the `/relations` endpoint.
Of note:
* No untyped defs in `register_new_matrix_user`
This one might be contraversial. `request_registration` has three
dependency-injection arguments used for testing. I'm removing the
injection of the `requests` module and using `unitest.mock.patch` in the
test cases instead.
Doing `reveal_type(requests)` and `reveal_type(requests.get)` before the
change:
```
synapse/_scripts/register_new_matrix_user.py:45: note: Revealed type is "Any"
synapse/_scripts/register_new_matrix_user.py:46: note: Revealed type is "Any"
```
And after:
```
synapse/_scripts/register_new_matrix_user.py:44: note: Revealed type is "types.ModuleType"
synapse/_scripts/register_new_matrix_user.py:45: note: Revealed type is "def (url: Union[builtins.str, builtins.bytes], params: Union[Union[_typeshed.SupportsItems[Union[builtins.str, builtins.bytes, builtins.int, builtins.float], Union[builtins.str, builtins.bytes, builtins.int, builtins.float, typing.Iterable[Union[builtins.str, builtins.bytes, builtins.int, builtins.float]], None]], Tuple[Union[builtins.str, builtins.bytes, builtins.int, builtins.float], Union[builtins.str, builtins.bytes, builtins.int, builtins.float, typing.Iterable[Union[builtins.str, builtins.bytes, builtins.int, builtins.float]], None]], typing.Iterable[Tuple[Union[builtins.str, builtins.bytes, builtins.int, builtins.float], Union[builtins.str, builtins.bytes, builtins.int, builtins.float, typing.Iterable[Union[builtins.str, builtins.bytes, builtins.int, builtins.float]], None]]], builtins.str, builtins.bytes], None] =, data: Union[Any, None] =, headers: Union[Any, None] =, cookies: Union[Any, None] =, files: Union[Any, None] =, auth: Union[Any, None] =, timeout: Union[Any, None] =, allow_redirects: builtins.bool =, proxies: Union[Any, None] =, hooks: Union[Any, None] =, stream: Union[Any, None] =, verify: Union[Any, None] =, cert: Union[Any, None] =, json: Union[Any, None] =) -> requests.models.Response"
```
* Drive-by comment in `synapse.storage.types`
* No untyped defs in `synapse_port_db`
This was by far the most painful. I'm happy to break this up into
smaller pieces for review if it's not managable as-is.
