Module developers +are encouraged to implement `check_event_for_spam` from the spam checker category instead. +</span>** + +Called when processing any incoming event, with the event and a `StateMap` +representing the current state of the room the event is being sent into. A `StateMap` is +a dictionary that maps tuples containing an event type and a state key to the +corresponding state event. For example retrieving the room's `m.room.create` event from +the `state_events` argument would look like this: `state_events.get(("m.room.create", ""))`. +The module must return a boolean indicating whether the event can be allowed. + +Note that this callback function processes incoming events coming via federation +traffic (on top of client traffic). This means denying an event might cause the local +copy of the room's history to diverge from that of remote servers. This may cause +federation issues in the room. It is strongly recommended to only deny events using this +callback function if the sender is a local user, or in a private federation in which all +servers are using the same module, with the same configuration. + +If the boolean returned by the module is `True`, it may also tell Synapse to replace the +event with new data by returning the new event's data as a dictionary. In order to do +that, it is recommended the module calls `event.get_dict()` to get the current event as a +dictionary, and modify the returned dictionary accordingly. + +Note that replacing the event only works for events sent by local users, not for events +received over federation. + +```python +async def on_create_room( + requester: "synapse.types.Requester", + request_content: dict, + is_requester_admin: bool, +) -> None +``` + +Called when processing a room creation request, with the `Requester` object for the user +performing the request, a dictionary representing the room creation request's JSON body +(see [the spec](https://matrix.org/docs/spec/client_server/latest#post-matrix-client-r0-createroom) +for a list of possible parameters), and a boolean indicating whether the user performing +the request is a server admin. + +Modules can modify the `request_content` (by e.g. adding events to its `initial_state`), +or deny the room's creation by raising a `module_api.errors.SynapseError`. + + ### 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: diff --git a/docs/sample_config.yaml b/docs/sample_config.yaml index f4845a5841..853c2f6899 100644 --- a/docs/sample_config.yaml +++ b/docs/sample_config.yaml @@ -2654,19 +2654,6 @@ stats: # action: allow -# Server admins can define a Python module that implements extra rules for -# allowing or denying incoming events.
