These are mainly used to +help avoid confusion if the Synapse codebase is rolled back after the database is +updated. They work as follows: + + * The Synapse codebase defines a constant `synapse.storage.schema.SCHEMA_VERSION` + which represents the expectations made about the database by that version. For + example, as of Synapse v1.36, this is `59`. + + * The database stores a "compatibility version" in + `schema_compat_version.compat_version` which defines the `SCHEMA_VERSION` of the + oldest version of Synapse which will work with the database. On startup, if + `compat_version` is found to be newer than `SCHEMA_VERSION`, Synapse will refuse to + start. + + Synapse automatically updates this field from + `synapse.storage.schema.SCHEMA_COMPAT_VERSION`. + + * Whenever a backwards-incompatible change is made to the database format (normally + via a `delta` file), `synapse.storage.schema.SCHEMA_COMPAT_VERSION` is also updated + so that administrators can not accidentally roll back to a too-old version of Synapse. + +Generally, the goal is to maintain compatibility with at least one or two previous +releases of Synapse, so any substantial change tends to require multiple releases and a +bit of forward-planning to get right. + +As a worked example: we want to remove the `room_stats_historical` table. Here is how it +might pan out. + + 1. Replace any code that *reads* from `room_stats_historical` with alternative + implementations, but keep writing to it in case of rollback to an earlier version. + Also, increase `synapse.storage.schema.SCHEMA_VERSION`. In this + instance, there is no existing code which reads from `room_stats_historical`, so + our starting point is: + + v1.36.0: `SCHEMA_VERSION=59`, `SCHEMA_COMPAT_VERSION=59` + + 2. Next (say in Synapse v1.37.0): remove the code that *writes* to + `room_stats_historical`, but don’t yet remove the table in case of rollback to + v1.36.0. Again, we increase `synapse.storage.schema.SCHEMA_VERSION`, but + because we have not broken compatibility with v1.36, we do not yet update + `SCHEMA_COMPAT_VERSION`. We now have: + + v1.37.0: `SCHEMA_VERSION=60`, `SCHEMA_COMPAT_VERSION=59`. + + 3. Later (say in Synapse v1.38.0): we can remove the table altogether. This will + break compatibility with v1.36.0, so we must update `SCHEMA_COMPAT_VERSION` accordingly. + There is no need to update `synapse.storage.schema.SCHEMA_VERSION`, since there is no + change to the Synapse codebase here. So we end up with: + + v1.38.0: `SCHEMA_VERSION=60`, `SCHEMA_COMPAT_VERSION=60`. + +If in doubt about whether to update `SCHEMA_VERSION` or not, it is generally best to +lean towards doing so. + +## Full schema dumps + +In the `full_schemas` directories, only the most recently-numbered snapshot is used +(`54` at the time of writing).

It may also verify +that the configuration is correct, and raise an instance of +`synapse.module_api.errors.ConfigError` if not. + +### Registering a web resource + +Modules can register web resources onto Synapse's web server using the following module +API method: + +```python +def ModuleApi.register_web_resource(path: str, resource: IResource) +``` + +The path is the full absolute path to register the resource at. For example, if you +register a resource for the path `/_synapse/client/my_super_module/say_hello`, Synapse +will serve it at `http(s)://[HS_URL]/_synapse/client/my_super_module/say_hello`. Note +that Synapse does not allow registering resources for several sub-paths in the `/_matrix` +namespace (such as anything under `/_matrix/client` for example). It is strongly +recommended that modules register their web resources under the `/_synapse/client` +namespace. + +The provided resource is a Python class that implements Twisted's [IResource](https://twistedmatrix.com/documents/current/api/twisted.web.resource.IResource.html) +interface (such as [Resource](https://twistedmatrix.com/documents/current/api/twisted.web.resource.Resource.html)). + +Only one resource can be registered for a given path. If several modules attempt to +register a resource for the same path, the module that appears first in Synapse's +configuration file takes priority. + +Modules **must** register their web resources in their `__init__` method. + +### Registering a callback + +Modules can use Synapse's module API to register callbacks. Callbacks are functions that +Synapse will call when performing specific actions. Callbacks must be asynchronous, and +are split in categories. A single module may implement callbacks from multiple categories, +and is under no obligation to implement all callbacks from the categories it registers +callbacks for. + +#### Spam checker callbacks + +To register one of the callbacks described in this section, a module needs to use the +module API's `register_spam_checker_callbacks` method. The callback functions are passed +to `register_spam_checker_callbacks` as keyword arguments, with the callback name as the +argument name and the function as its value. This is demonstrated in the example below. + +The available spam checker callbacks are: + +```python +async def check_event_for_spam(event: "synapse.events.EventBase") -> Union[bool, str] +``` + +Called when receiving an event from a client or via federation. The module can return +either a `bool` to indicate whether the event must be rejected because of spam, or a `str` +to indicate the event must be rejected because of spam and to give a rejection reason to +forward to clients. + +```python +async def user_may_invite(inviter: str, invitee: str, room_id: str) -> bool +``` + +Called when processing an invitation. The module must return a `bool` indicating whether +the inviter can invite the invitee to the given room. Both inviter and invitee are +represented by their Matrix user ID (i.e. `@alice:example.com`). + +```python +async def user_may_create_room(user: str) -> bool +``` + +Called when processing a room creation request. The module must return a `bool` indicating +whether the given user (represented by their Matrix user ID) is allowed to create a room. + +```python +async def user_may_create_room_alias(user: str, room_alias: "synapse.types.RoomAlias") -> bool +``` + +Called when trying to associate an alias with an existing room. The module must return a +`bool` indicating whether the given user (represented by their Matrix user ID) is allowed +to set the given alias. + +```python +async def user_may_publish_room(user: str, room_id: str) -> bool +``` + +Called when trying to publish a room to the homeserver's public rooms directory. The +module must return a `bool` indicating whether the given user (represented by their +Matrix user ID) is allowed to publish the given room. + +```python +async def check_username_for_spam(user_profile: Dict[str, str]) -> bool +``` + +Called when computing search results in the user directory. The module must return a +`bool` indicating whether the given user profile can appear in search results. The profile +is represented as a dictionary with the following keys: + +* `user_id`: The Matrix ID for this user. +* `display_name`: The user's display name. +* `avatar_url`: The `mxc://` URL to the user's avatar. + +The module is given a copy of the original dictionary, so modifying it from within the +module cannot modify a user's profile when included in user directory search results. + +```python +async def check_registration_for_spam( + email_threepid: Optional[dict], + username: Optional[str], + request_info: Collection[Tuple[str, str]], + auth_provider_id: Optional[str] = None, +) -> "synapse.spam_checker_api.RegistrationBehaviour" +``` + +Called when registering a new user. The module must return a `RegistrationBehaviour` +indicating whether the registration can go through or must be denied, or whether the user +may be allowed to register but will be shadow banned. + +The arguments passed to this callback are: + +* `email_threepid`: The email address used for registering, if any. +* `username`: The username the user would like to register. Can be `None`, meaning that + Synapse will generate one later. +* `request_info`: A collection of tuples, which first item is a user agent, and which + second item is an IP address. These user agents and IP addresses are the ones that were + used during the registration process. +* `auth_provider_id`: The identifier of the SSO authentication provider, if any. + +```python +async def check_media_file_for_spam( + file_wrapper: "synapse.rest.media.v1.media_storage.ReadableFileWrapper", + file_info: "synapse.rest.media.v1._base.FileInfo" +) -> bool +``` + +Called when storing a local or remote file. The module must return a boolean indicating +whether the given file can be stored in the homeserver's media store. + +### Porting an existing module that uses the old interface + +In order to port a module that uses Synapse's old module interface, its author needs to: + +* ensure the module's callbacks are all asynchronous. +* register their callbacks using one or more of the `register_[...]_callbacks` methods + from the `ModuleApi` class in the module's `__init__` method (see [this section](#registering-a-web-resource) + for more info). + +Additionally, if the module is packaged with an additional web resource, the module +should register this resource in its `__init__` method using the `register_web_resource` +method from the `ModuleApi` class (see [this section](#registering-a-web-resource) for +more info). + +The module's author should also update any example in the module's configuration to only +use the new `modules` section in Synapse's configuration file (see [this section](#using-modules) +for more info). + +### Example + +The example below is a module that implements the spam checker callback +`user_may_create_room` to deny room creation to user `@evilguy:example.com`, and registers +a web resource to the path `/_synapse/client/demo/hello` that returns a JSON object. + +```python +import json + +from twisted.web.resource import Resource +from twisted.web.server import Request + +from synapse.module_api import ModuleApi + + +class DemoResource(Resource): + def __init__(self, config): + super(DemoResource, self).__init__() + self.config = config + + def render_GET(self, request: Request): + name = request.args.get(b"name")[0] + request.setHeader(b"Content-Type", b"application/json") + return json.dumps({"hello": name}) + + +class DemoModule: + def __init__(self, config: dict, api: ModuleApi): + self.config = config + self.api = api + + self.api.register_web_resource( + path="/_synapse/client/demo/hello", + resource=DemoResource(self.config), + ) + + self.api.register_spam_checker_callbacks( + user_may_create_room=self.user_may_create_room, + ) + + @staticmethod + def parse_config(config): + return config + + async def user_may_create_room(self, user: str) -> bool: + if user == "@evilguy:example.com": + return False + + return True +``` diff --git a/docs/presence_router_module.md b/docs/presence_router_module.md index d2844915..bf859e42 100644 --- a/docs/presence_router_module.md +++ b/docs/presence_router_module.md @@ -30,7 +30,7 @@ presence to (for those users that the receiving user is considered interested in It does not include state for users who are currently offline, and it can only be called on workers that support sending federation.
