Synapse 1.46.0rc1 (2021-10-26)
==============================
The cause of the [performance regression affecting Synapse 1.44](https://github.com/matrix-org/synapse/issues/11049) has been identified and fixed. ([\#11177](https://github.com/matrix-org/synapse/issues/11177))
Features
--------
- Add support for Ubuntu 21.10 "Impish Indri". ([\#11024](https://github.com/matrix-org/synapse/issues/11024))
- Port the Password Auth Providers module interface to the new generic interface. ([\#10548](https://github.com/matrix-org/synapse/issues/10548), [\#11180](https://github.com/matrix-org/synapse/issues/11180))
- Experimental support for the thread relation defined in [MSC3440](https://github.com/matrix-org/matrix-doc/pull/3440). ([\#11088](https://github.com/matrix-org/synapse/issues/11088), [\#11181](https://github.com/matrix-org/synapse/issues/11181), [\#11192](https://github.com/matrix-org/synapse/issues/11192))
- Users admin API can now also modify user type in addition to allowing it to be set on user creation. ([\#11174](https://github.com/matrix-org/synapse/issues/11174))
Bugfixes
--------
- Newly-created public rooms are now only assigned an alias if the room's creation has not been blocked by permission settings. Contributed by @AndrewFerr. ([\#10930](https://github.com/matrix-org/synapse/issues/10930))
- Fix a long-standing bug which meant that events received over federation were sometimes incorrectly accepted into the room state. ([\#11001](https://github.com/matrix-org/synapse/issues/11001), [\#11009](https://github.com/matrix-org/synapse/issues/11009), [\#11012](https://github.com/matrix-org/synapse/issues/11012))
- Fix 500 error on `/messages` when the server accumulates more than 5 backwards extremities at a given depth for a room. ([\#11027](https://github.com/matrix-org/synapse/issues/11027))
- Fix a bug where setting a user's `external_id` via the admin API returns 500 and deletes user's existing external mappings if that external ID is already mapped. ([\#11051](https://github.com/matrix-org/synapse/issues/11051))
- Fix a long-standing bug where users excluded from the user directory were added into the directory if they belonged to a room which became public or private. ([\#11075](https://github.com/matrix-org/synapse/issues/11075))
- Fix a long-standing bug when attempting to preview URLs which are in the `windows-1252` character encoding. ([\#11077](https://github.com/matrix-org/synapse/issues/11077), [\#11089](https://github.com/matrix-org/synapse/issues/11089))
- Fix broken export-data admin command and add test script checking the command to CI. ([\#11078](https://github.com/matrix-org/synapse/issues/11078))
- Show an error when timestamp in seconds is provided to the `/purge_media_cache` Admin API. ([\#11101](https://github.com/matrix-org/synapse/issues/11101))
- Fix local users who left all their rooms being removed from the user directory, even if the `search_all_users` config option was enabled. ([\#11103](https://github.com/matrix-org/synapse/issues/11103))
- Fix a bug which caused the module API's `get_user_ip_and_agents` function to always fail on workers. `get_user_ip_and_agents` was introduced in 1.44.0 and did not function correctly on worker processes at the time. ([\#11112](https://github.com/matrix-org/synapse/issues/11112))
- Identity server connection is no longer ignoring `ip_range_whitelist`. ([\#11120](https://github.com/matrix-org/synapse/issues/11120))
- Fix a bug introduced in Synapse 1.45.0 breaking the configuration file parsing script. ([\#11145](https://github.com/matrix-org/synapse/issues/11145))
- Fix a performance regression introduced in 1.44.0 which could cause client requests to time out when making large numbers of outbound requests. ([\#11177](https://github.com/matrix-org/synapse/issues/11177), [\#11190](https://github.com/matrix-org/synapse/issues/11190))
- Resolve and share `state_groups` for all [MSC2716](https://github.com/matrix-org/matrix-doc/pull/2716) historical events in batch. ([\#10975](https://github.com/matrix-org/synapse/issues/10975))
Improved Documentation
----------------------
- Fix broken links relating to module API deprecation in the upgrade notes. ([\#11069](https://github.com/matrix-org/synapse/issues/11069))
- Add more information about what happens when a user is deactivated. ([\#11083](https://github.com/matrix-org/synapse/issues/11083))
- Clarify the the sample log config can be copied from the documentation without issue. ([\#11092](https://github.com/matrix-org/synapse/issues/11092))
- Update the admin API documentation with an updated list of the characters allowed in registration tokens. ([\#11093](https://github.com/matrix-org/synapse/issues/11093))
- Document Synapse's behaviour when dealing with multiple modules registering the same callbacks and/or handlers for the same HTTP endpoints. ([\#11096](https://github.com/matrix-org/synapse/issues/11096))
- Fix instances of `[example]{.title-ref}` in the upgrade documentation as a result of prior RST to Markdown conversion. ([\#11118](https://github.com/matrix-org/synapse/issues/11118))
- Document the version of Synapse each module callback was introduced in. ([\#11132](https://github.com/matrix-org/synapse/issues/11132))
- Document the version of Synapse that introduced each module API method. ([\#11183](https://github.com/matrix-org/synapse/issues/11183))

- Add some extra logging to the event persistence code. ([\#11014](https://github.com/matrix-org/synapse/issues/11014))
- Rearrange the internal workings of the incremental user directory updates. ([\#11035](https://github.com/matrix-org/synapse/issues/11035))
- Fix a long-standing bug where users excluded from the directory could still be added to the `users_who_share_private_rooms` table after a regular user joins a private room. ([\#11143](https://github.com/matrix-org/synapse/issues/11143))

provenance of the modules they use on their homeserver and make sure the modules aren't

## Using multiple modules
Also note that we are currently in the process of migrating module interfaces to this
system. While some interfaces might be compatible with it, others still require
configuring modules in another part of Synapse's configuration file.
The order in which modules are listed in this section is important. When processing an
action that can be handled by several modules, Synapse will always prioritise the module
that appears first (i.e. is the highest in the list). This means:
* If several modules register the same callback, the callback registered by the module
that appears first is used.
* If several modules try to register a handler for the same HTTP path, only the handler
registered by the module that appears first is used. Handlers registered by the other
module(s) are ignored and Synapse will log a warning message about them.
Note that Synapse doesn't allow multiple modules implementing authentication checkers via
the password auth provider feature for the same login type with different fields. If this
happens, Synapse will refuse to start.
## Current status
We are currently in the process of migrating module interfaces to this system. While some
interfaces might be compatible with it, others still require configuring modules in
another part of Synapse's configuration file.
Currently, only the following pre-existing interfaces are compatible with this new system:
* spam checker
* third-party rules
* presence router
* password auth providers

# Password auth provider callbacks
Password auth providers offer a way for server administrators to integrate
their Synapse installation with an external authentication system. The callbacks can be
registered by using the Module API's `register_password_auth_provider_callbacks` method.
## Callbacks
### `auth_checkers`
_First introduced in Synapse v1.46.0_
```
auth_checkers: Dict[Tuple[str,Tuple], Callable]
```
A dict mapping from tuples of a login type identifier (such as `m.login.password`) and a
tuple of field names (such as `("password", "secret_thing")`) to authentication checking
callbacks, which should be of the following form:
```python
async def check_auth(
user: str,
login_type: str,
login_dict: "synapse.module_api.JsonDict",
) -> Optional[
Tuple[
str,
Optional[Callable[["synapse.module_api.LoginResponse"], Awaitable[None]]]
]
]
```
The login type and field names should be provided by the user in the
request to the `/login` API. [The Matrix specification](https://matrix.org/docs/spec/client_server/latest#authentication-types)
defines some types, however user defined ones are also allowed.
The callback is passed the `user` field provided by the client (which might not be in
`@username:server` form), the login type, and a dictionary of login secrets passed by
the client.
If the authentication is successful, the module must return the user's Matrix ID (e.g.
`@alice:example.com`) and optionally a callback to be called with the response to the
`/login` request. If the module doesn't wish to return a callback, it must return `None`
instead.
If the authentication is unsuccessful, the module must return `None`.
If multiple modules register an auth checker for the same login type but with different
fields, Synapse will refuse to start.
If multiple modules register an auth checker for the same login type with the same fields,
then the callbacks will be executed in order, until one returns a Matrix User ID (and
optionally a callback). In that case, the return value of that callback will be accepted
and subsequent callbacks will not be fired. If every callback returns `None`, then the
authentication fails.
### `check_3pid_auth`
_First introduced in Synapse v1.46.0_
```python
async def check_3pid_auth(
medium: str,
address: str,
password: str,
) -> Optional[
Tuple[
str,
Optional[Callable[["synapse.module_api.LoginResponse"], Awaitable[None]]]
]
]
```
Called when a user attempts to register or log in with a third party identifier,
such as email. It is passed the medium (eg. `email`), an address (eg. `jdoe@example.com`)
and the user's password.
If the authentication is successful, the module must return the user's Matrix ID (e.g.
`@alice:example.com`) and optionally a callback to be called with the response to the `/login` request.
If the module doesn't wish to return a callback, it must return None instead.
If the authentication is unsuccessful, the module must return `None`.
If multiple modules implement this callback, they will be considered in order. If a
callback returns `None`, Synapse falls through to the next one. The value of the first

### `on_logged_out`
_First introduced in Synapse v1.46.0_
```python
async def on_logged_out(
user_id: str,
device_id: Optional[str],
access_token: str
) -> None
```
Called during a logout request for a user. It is passed the qualified user ID, the ID of the
deactivated device (if any: access tokens are occasionally created without an associated
device ID), and the (now deactivated) access token.
If multiple modules implement this callback, Synapse runs them all in order.
## Example
The example module below implements authentication checkers for two different login types:
- `my.login.type`
- Expects a `my_field` field to be sent to `/login`
- Is checked by the method: `self.check_my_login`
- `m.login.password` (defined in [the spec](https://matrix.org/docs/spec/client_server/latest#password-based))
- Expects a `password` field to be sent to `/login`
- Is checked by the method: `self.check_pass`
```python
from typing import Awaitable, Callable, Optional, Tuple
import synapse
from synapse import module_api
