Deprecations and Removals
-------------------------
- The current spam checker interface is deprecated in favour of a new generic modules system. See the [upgrade notes](https://github.com/matrix-org/synapse/blob/master/UPGRADE.rst#deprecation-of-the-current-spam-checker-interface) for more information on how to update to the new system.

# ACME
From version 1.0 (June 2019) onwards, Synapse requires valid TLS
certificates for communication between servers (by default on port
`8448`) in addition to those that are client-facing (port `443`). To
help homeserver admins fulfil this new requirement, Synapse v0.99.0
introduced support for automatically provisioning certificates through
[Let's Encrypt](https://letsencrypt.org/) using the ACME protocol.
## Deprecation of ACME v1
In [March 2019](https://community.letsencrypt.org/t/end-of-life-plan-for-acmev1/88430),
Let's Encrypt announced that they were deprecating version 1 of the ACME
protocol, with the plan to disable the use of it for new accounts in
November 2019, for new domains in June 2020, and for existing accounts and
domains in June 2021.
Synapse doesn't currently support version 2 of the ACME protocol, which
means that:
* for existing installs, Synapse's built-in ACME support will continue
to work until June 2021.
* for new installs, this feature will not work at all.
Either way, it is recommended to move from Synapse's ACME support
feature to an external automated tool such as [certbot](https://github.com/certbot/certbot)
(or browse [this list](https://letsencrypt.org/fr/docs/client-options/)
for an alternative ACME client).
It's also recommended to use a reverse proxy for the server-facing
communications (more documentation about this can be found
[here](/docs/reverse_proxy.md)) as well as the client-facing ones and
have it serve the certificates.
In case you can't do that and need Synapse to serve them itself, make
sure to set the `tls_certificate_path` configuration setting to the path
of the certificate (make sure to use the certificate containing the full
certification chain, e.g. `fullchain.pem` if using certbot) and
`tls_private_key_path` to the path of the matching private key. Note
that in this case you will need to restart Synapse after each
certificate renewal so that Synapse stops using the old certificate.
If you still want to use Synapse's built-in ACME support, the rest of
this document explains how to set it up.
## Initial setup
In the case that your `server_name` config variable is the same as
the hostname that the client connects to, then the same certificate can be
used between client and federation ports without issue.
If your configuration file does not already have an `acme` section, you can
generate an example config by running the `generate_config` executable. For
example:
```
~/synapse/env3/bin/generate_config
```
You will need to provide Let's Encrypt (or another ACME provider) access to
your Synapse ACME challenge responder on port 80, at the domain of your
homeserver. This requires you to either change the port of the ACME listener
provided by Synapse to a high port and reverse proxy to it, or use a tool
like `authbind` to allow Synapse to listen on port 80 without root access.
(Do not run Synapse with root permissions!) Detailed instructions are
available under "ACME setup" below.
If you already have certificates, you will need to back up or delete them
(files `example.com.tls.crt` and `example.com.tls.key` in Synapse's root
directory), Synapse's ACME implementation will not overwrite them.
## ACME setup
The main steps for enabling ACME support in short summary are:
1. Allow Synapse to listen for incoming ACME challenges.
1. Enable ACME support in `homeserver.yaml`.
1. Move your old certificates (files `example.com.tls.crt` and `example.com.tls.key` out of the way if they currently exist at the paths specified in `homeserver.yaml`.
1. Restart Synapse.
Detailed instructions for each step are provided below.
### Listening on port 80
In order for Synapse to complete the ACME challenge to provision a
certificate, it needs access to port 80. Typically listening on port 80 is
only granted to applications running as root. There are thus two solutions to
this problem.
#### Using a reverse proxy
A reverse proxy such as Apache or nginx allows a single process (the web
server) to listen on port 80 and proxy traffic to the appropriate program
running on your server. It is the recommended method for setting up ACME as
it allows you to use your existing webserver while also allowing Synapse to
provision certificates as needed.
For nginx users, add the following line to your existing `server` block:
```
location /.well-known/acme-challenge {
proxy_pass http://localhost:8009;
}
```
For Apache, add the following to your existing webserver config:
```
ProxyPass /.well-known/acme-challenge http://localhost:8009/.well-known/acme-challenge
```
Make sure to restart/reload your webserver after making changes.
Now make the relevant changes in `homeserver.yaml` to enable ACME support:
```
acme:
enabled: true
port: 8009
```
#### Authbind
`authbind` allows a program which does not run as root to bind to
low-numbered ports in a controlled way. The setup is simpler, but requires a
webserver not to already be running on port 80. **This includes every time
Synapse renews a certificate**, which may be cumbersome if you usually run a
web server on port 80. Nevertheless, if you're sure port 80 is not being used
for any other purpose then all that is necessary is the following:
Install `authbind`. For example, on Debian/Ubuntu:
```
sudo apt-get install authbind
```
Allow `authbind` to bind port 80:
```
sudo touch /etc/authbind/byport/80
sudo chmod 777 /etc/authbind/byport/80
```
When Synapse is started, use the following syntax:
```
authbind --deep <synapse start command>
```
Make the relevant changes in `homeserver.yaml` to enable ACME support:
```
acme:
enabled: true
```
### (Re)starting synapse
Ensure that the certificate paths specified in `homeserver.yaml` (`tls_certificate_path` and `tls_private_key_path`) do not currently point to any files. Synapse will not provision certificates if files exist, as it does not want to overwrite existing certificates.
Finally, start/restart Synapse.

# Modules
Synapse supports extending its functionality by configuring external modules.
## Using modules
To use a module on Synapse, add it to the `modules` section of the configuration file:
```yaml
modules:
- module: my_super_module.MySuperClass
config:
do_thing: true
- module: my_other_super_module.SomeClass
config: {}
```
Each module is defined by a path to a Python class as well as a configuration. This
information for a given module should be available in the module's own documentation.
**Note**: When using third-party modules, you effectively allow someone else to run
custom code on your Synapse homeserver. Server admins are encouraged to verify the
provenance of the modules they use on their homeserver and make sure the modules aren't
running malicious code on their instance.
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. Currently, only the
spam checker interface is compatible with this new system.
## Writing a module
A module is a Python class that uses Synapse's module API to interact with the
homeserver. It can register callbacks that Synapse will call on specific operations, as
well as web resources to attach to Synapse's web server.
When instantiated, a module is given its parsed configuration as well as an instance of
the `synapse.module_api.ModuleApi` class. The configuration is a dictionary, and is
either the output of the module's `parse_config` static method (see below), or the
configuration associated with the module in Synapse's configuration file.
See the documentation for the `ModuleApi` class
[here](https://github.com/matrix-org/synapse/blob/master/synapse/module_api/__init__.py).
### Handling the module's configuration
A module can implement the following static method:
```python
@staticmethod
def parse_config(config: dict) -> dict
```
This method is given a dictionary resulting from parsing the YAML configuration for the
module. It may modify it (for example by parsing durations expressed as strings (e.g.
"5d") into milliseconds, etc.), and return the modified dictionary. 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
```

#
# * If you already have an Apache, Nginx, or similar listening on port 80,
