+# Synapse Docker
+
+The `matrixdotorg/synapse` Docker image will run Synapse as a single process. It does not provide a
+database server or a TURN server, you should run these separately.
+
+If you run a Postgres server, you should simply include it in the same Compose
+project or set the proper environment variables and the image will automatically
+use that server.
+
+## Build
+
+Build the docker image with the `docker build` command from the root of the synapse repository.
+
+```
+docker build -t docker.io/matrixdotorg/synapse .
+```
+
+The `-t` option sets the image tag. Official images are tagged `matrixdotorg/synapse:<version>` where `<version>` is the same as the release tag in the synapse git repository.
+
+You may have a local Python wheel cache available, in which case copy the relevant packages in the ``cache/`` directory at the root of the project.
+
+## Run
+
+This image is designed to run either with an automatically generated configuration
+file or with a custom configuration that requires manual edition.
+
+### Automated configuration
+
+It is recommended that you use Docker Compose to run your containers, including
+this image and a Postgres server. A sample ``docker-compose.yml`` is provided,
+including example labels for reverse proxying and other artifacts.
+
+Read the section about environment variables and set at least mandatory variables,
+then run the server:

+docker-compose up -d
+```
+
+If secrets are not specified in the environment variables, they will be generated
+as part of the startup. Please ensure these secrets are kept between launches of the
+Docker container, as their loss may require users to log in again.
+
+### Manual configuration
+
+A sample ``docker-compose.yml`` is provided, including example labels for
+reverse proxying and other artifacts. The docker-compose file is an example,
+please comment/uncomment sections that are not suitable for your usecase.
+
+Specify a ``SYNAPSE_CONFIG_PATH``, preferably to a persistent path,
+to use manual configuration. To generate a fresh ``homeserver.yaml``, simply run:
+
+```
+docker-compose run --rm -e SYNAPSE_SERVER_NAME=my.matrix.host synapse generate
+```
+
+Then, customize your configuration and run the server:
+
+```
+docker-compose up -d
+```
+
+### Without Compose
+
+If you do not wish to use Compose, you may still run this image using plain
+Docker commands. Note that the following is just a guideline and you may need
+to add parameters to the docker run command to account for the network situation
+with your postgres database.
+
+```
+docker run \
+    -d \
+    --name synapse \
+    -v ${DATA_PATH}:/data \
+    -e SYNAPSE_SERVER_NAME=my.matrix.host \
+    -e SYNAPSE_REPORT_STATS=yes \
+    docker.io/matrixdotorg/synapse:latest
+```
+
+## Volumes
+
+The image expects a single volume, located at ``/data``, that will hold:
+
+* temporary files during uploads;
+* uploaded media and thumbnails;
+* the SQLite database if you do not configure postgres;
+* the appservices configuration.
+
+You are free to use separate volumes depending on storage endpoints at your
+disposal. For instance, ``/data/media`` coud be stored on a large but low
+performance hdd storage while other files could be stored on high performance
+endpoints.
+
+In order to setup an application service, simply create an ``appservices``
+directory in the data volume and write the application service Yaml
+configuration file there. Multiple application services are supported.
+
+## Environment
+
+Unless you specify a custom path for the configuration file, a very generic
+file will be generated, based on the following environment settings.
+These are a good starting point for setting up your own deployment.
+
+Global settings:
+
+* ``UID``, the user id Synapse will run as [default 991]
+* ``GID``, the group id Synapse will run as [default 991]
+* ``SYNAPSE_CONFIG_PATH``, path to a custom config file
+
+If ``SYNAPSE_CONFIG_PATH`` is set, you should generate a configuration file
+then customize it manually. No other environment variable is required.
+
+Otherwise, a dynamic configuration file will be used. The following environment
+variables are available for configuration:
+
+* ``SYNAPSE_SERVER_NAME`` (mandatory), the current server public hostname.
+* ``SYNAPSE_REPORT_STATS``, (mandatory, ``yes`` or ``no``), enable anonymous
+  statistics reporting back to the Matrix project which helps us to get funding.
+* ``SYNAPSE_NO_TLS``, set this variable to disable TLS in Synapse (use this if
+  you run your own TLS-capable reverse proxy).
+* ``SYNAPSE_ENABLE_REGISTRATION``, set this variable to enable registration on
+  the Synapse instance.
+* ``SYNAPSE_ALLOW_GUEST``, set this variable to allow guest joining this server.
+* ``SYNAPSE_EVENT_CACHE_SIZE``, the event cache size [default `10K`].
+* ``SYNAPSE_CACHE_FACTOR``, the cache factor [default `0.5`].
+* ``SYNAPSE_RECAPTCHA_PUBLIC_KEY``, set this variable to the recaptcha public
+  key in order to enable recaptcha upon registration.
+* ``SYNAPSE_RECAPTCHA_PRIVATE_KEY``, set this variable to the recaptcha private
+  key in order to enable recaptcha upon registration.
+* ``SYNAPSE_TURN_URIS``, set this variable to the coma-separated list of TURN
+  uris to enable TURN for this homeserver.
+* ``SYNAPSE_TURN_SECRET``, set this to the TURN shared secret if required.
+
+Shared secrets, that will be initialized to random values if not set:
+
+* ``SYNAPSE_REGISTRATION_SHARED_SECRET``, secret for registrering users if
+  registration is disable.
+* ``SYNAPSE_MACAROON_SECRET_KEY`` secret for signing access tokens
+  to the server.
+
+Database specific values (will use SQLite if not set):
+
+* `POSTGRES_DB` - The database name for the synapse postgres database. [default: `synapse`]
+* `POSTGRES_HOST` - The host of the postgres database if you wish to use postgresql instead of sqlite3. [default: `db` which is useful when using a container on the same docker network in a compose file where the postgres service is called `db`]
+* `POSTGRES_PASSWORD` - The password for the synapse postgres database. **If this is set then postgres will be used instead of sqlite3.** [default: none] **NOTE**: You are highly encouraged to use postgresql! Please use the compose file to make it easier to deploy.
+* `POSTGRES_USER` - The user for the synapse postgres database. [default: `matrix`]
+
+Mail server specific values (will not send emails if not set):
+
+* ``SYNAPSE_SMTP_HOST``, hostname to the mail server.
+* ``SYNAPSE_SMTP_PORT``, TCP port for accessing the mail server [default ``25``].
+* ``SYNAPSE_SMTP_USER``, username for authenticating against the mail server if any.
+* ``SYNAPSE_SMTP_PASSWORD``, password for authenticating against the mail server if any.

+
+To use it, first install prometheus by following the instructions at
+
+  http://prometheus.io/
+
+### for Prometheus v1
+Add a new job to the main prometheus.conf file:
+
+  job: {
+    name: "synapse"
+
+    target_group: {
+      target: "http://SERVER.LOCATION.HERE:PORT/_synapse/metrics"
+    }

+### for Prometheus v2
+Add a new job to the main prometheus.yml file:
+
+  - job_name: "synapse"
+    metrics_path: "/_synapse/metrics"
+    # when endpoint uses https:
+    scheme: "https"
+
+    static_configs:
+    - targets: ['SERVER.LOCATION:PORT']
+
+To use `synapse.rules` add
+
+    rule_files:
+      - "/PATH/TO/synapse-v2.rules"
+
+Metrics are disabled by default when running synapse; they must be enabled
+with the 'enable-metrics' option, either in the synapse config file or as a
+command-line option.

-``POST /_matrix/client/r0/admin/purge_history/<room_id>/<event_id>``
+``POST /_matrix/client/r0/admin/purge_history/<room_id>[/<event_id>]``
 
 including an ``access_token`` of a server admin.
+
+By default, events sent by local users are not deleted, as they may represent
+the only copies of this content in existence. (Events sent by remote users are
+deleted.)
+
+Room state data (such as joins, leaves, topic) is always preserved.
+
+To delete local message events as well, set ``delete_local_events`` in the body:
+
+.. code:: json
+
+   {
+       "delete_local_events": true
+   }
+
+The caller must specify the point in the room to purge up to. This can be
+specified by including an event_id in the URI, or by setting a
+``purge_up_to_event_id`` or ``purge_up_to_ts`` in the request body. If an event
+id is given, that event (and others at the same graph depth) will be retained.
+If ``purge_up_to_ts`` is given, it should be a timestamp since the unix epoch,

+Shared-Secret Registration
+==========================
+
+This API allows for the creation of users in an administrative and
+non-interactive way. This is generally used for bootstrapping a Synapse
+instance with administrator accounts.
+
+To authenticate yourself to the server, you will need both the shared secret
+(``registration_shared_secret`` in the homeserver configuration), and a
+one-time nonce. If the registration shared secret is not configured, this API
+is not enabled.
+
+To fetch the nonce, you need to request one from the API::
+
+  > GET /_matrix/client/r0/admin/register
+
+  < {"nonce": "thisisanonce"}
+
+Once you have the nonce, you can make a ``POST`` to the same URL with a JSON
+body containing the nonce, username, password, whether they are an admin
+(optional, False by default), and a HMAC digest of the content.
+
+As an example::
+
+  > POST /_matrix/client/r0/admin/register
+  > {
+     "nonce": "thisisanonce",
+     "username": "pepper_roni",
+     "password": "pizza",
+     "admin": true,
+     "mac": "mac_digest_here"
+    }
+
+  < {
+     "access_token": "token_here",
+     "user_id": "@pepper_roni@test",
+     "home_server": "test",
+     "device_id": "device_id_here"
+    }
+
+The MAC is the hex digest output of the HMAC-SHA1 algorithm, with the key being
+the shared secret and the content being the nonce, user, password, and either
+the string "admin" or "notadmin", each separated by NULs. For an example of
+generation in Python::
+
+  import hmac, hashlib
+
+  def generate_mac(nonce, user, password, admin=False):
+
+      mac = hmac.new(
+        key=shared_secret,
+        digestmod=hashlib.sha1,
+      )
+
+      mac.update(nonce.encode('utf8'))
+      mac.update(b"\x00")
+      mac.update(user.encode('utf8'))
+      mac.update(b"\x00")
+      mac.update(password.encode('utf8'))
+      mac.update(b"\x00")
+      mac.update(b"admin" if admin else b"notadmin")

+Support in Synapse for tracking agreement to server terms and conditions
+========================================================================
+
+Synapse 0.30 introduces support for tracking whether users have agreed to the
+terms and conditions set by the administrator of a server - and blocking access
+to the server until they have.
+
+There are several parts to this functionality; each requires some specific
+configuration in `homeserver.yaml` to be enabled.
+
+Note that various parts of the configuation and this document refer to the
+"privacy policy": agreement with a privacy policy is one particular use of this
+feature, but of course adminstrators can specify other terms and conditions
+unrelated to "privacy" per se.
+
+Collecting policy agreement from a user
+---------------------------------------
+
+Synapse can be configured to serve the user a simple policy form with an
+"accept" button. Clicking "Accept" records the user's acceptance in the
+database and shows a success page.
+
+To enable this, first create templates for the policy and success pages.
+These should be stored on the local filesystem.
+
+These templates use the [Jinja2](http://jinja.pocoo.org) templating language,
+and [docs/privacy_policy_templates](privacy_policy_templates) gives
+examples of the sort of thing that can be done.
+
+Note that the templates must be stored under a name giving the language of the
+template - currently this must always be `en` (for "English");
+internationalisation support is intended for the future.
+
+The template for the policy itself should be versioned and named according to 
+the version: for example `1.0.html`. The version of the policy which the user
+has agreed to is stored in the database.
+
+Once the templates are in place, make the following changes to `homeserver.yaml`:
+
+ 1. Add a `user_consent` section, which should look like:
+
+    ```yaml
+    user_consent:
+      template_dir: privacy_policy_templates
+      version: 1.0
+    ```
+
+    `template_dir` points to the directory containing the policy
+    templates. `version` defines the version of the policy which will be served
+    to the user. In the example above, Synapse will serve
+    `privacy_policy_templates/en/1.0.html`.
+
+
+ 2. Add a `form_secret` setting at the top level:
+
+
+    ```yaml
+    form_secret: "<unique secret>"
+    ```
+
+    This should be set to an arbitrary secret string (try `pwgen -y 30` to
+    generate suitable secrets).
+
+    More on what this is used for below.
+
+ 3. Add `consent` wherever the `client` resource is currently enabled in the
+    `listeners` configuration. For example:
+
+    ```yaml
+    listeners:
+      - port: 8008
+        resources:
+          - names:
+            - client
+            - consent
+    ```
+
+
+Finally, ensure that `jinja2` is installed. If you are using a virtualenv, this
+should be a matter of `pip install Jinja2`. On debian, try `apt-get install
+python-jinja2`.
+
+Once this is complete, and the server has been restarted, try visiting
+`https://<server>/_matrix/consent`. If correctly configured, this should give
+an error "Missing string query parameter 'u'". It is now possible to manually
+construct URIs where users can give their consent.
+
+### Constructing the consent URI
+
+It may be useful to manually construct the "consent URI" for a given user - for
+instance, in order to send them an email asking them to consent. To do this,
+take the base `https://<server>/_matrix/consent` URL and add the following
+query parameters:
+
+ * `u`: the user id of the user. This can either be a full MXID
+   (`@user:server.com`) or just the localpart (`user`).
+
+ * `h`: hex-encoded HMAC-SHA256 of `u` using the `form_secret` as a key. It is
+   possible to calculate this on the commandline with something like:
+
+   ```bash
+   echo -n '<user>' | openssl sha256 -hmac '<form_secret>'
+   ```
+
+   This should result in a URI which looks something like:
+   `https://<server>/_matrix/consent?u=<user>&h=68a152465a4d...`.
+
+
+Sending users a server notice asking them to agree to the policy
+----------------------------------------------------------------
+
+It is possible to configure Synapse to send a [server
+notice](server_notices.md) to anybody who has not yet agreed to the current
+version of the policy. To do so:
+
+ * ensure that the consent resource is configured, as in the previous section
+
+ * ensure that server notices are configured, as in [server_notices.md](server_notices.md).
+
+ * Add `server_notice_content` under `user_consent` in `homeserver.yaml`. For
+   example:
+
+   ```yaml
+   user_consent:
+     server_notice_content:
+       msgtype: m.text
+       body: >-
+         Please give your consent to the privacy policy at %(consent_uri)s.
+   ```
+
+   Synapse automatically replaces the placeholder `%(consent_uri)s` with the
+   consent uri for that user.
+
+ * ensure that `public_baseurl` is set in `homeserver.yaml`, and gives the base
+   URI that clients use to connect to the server. (It is used to construct
+   `consent_uri` in the server notice.)
+
+
+Blocking users from using the server until they agree to the policy
+-------------------------------------------------------------------
+
+Synapse can be configured to block any attempts to join rooms or send messages
+until the user has given their agreement to the policy. (Joining the server
+notices room is exempted from this).
+
+To enable this, add `block_events_error` under `user_consent`. For example:
+
+```yaml
+user_consent:
+  block_events_error: >-
+    You can't send any messages until you consent to the privacy policy at
+    %(consent_uri)s.
+```
+
+Synapse automatically replaces the placeholder `%(consent_uri)s` with the
+consent uri for that user.
+
+ensure that `public_baseurl` is set in `homeserver.yaml`, and gives the base
+URI that clients use to connect to the server. (It is used to construct
+`consent_uri` in the error.)

+Using the synapse manhole
+=========================
+
+The "manhole" allows server administrators to access a Python shell on a running
+Synapse installation. This is a very powerful mechanism for administration and
+debugging.
+
+To enable it, first uncomment the `manhole` listener configuration in
+`homeserver.yaml`:
+
+```yaml
+listeners:
+  - port: 9000
+    bind_addresses: ['::1', '127.0.0.1']
+    type: manhole
+```
+
+(`bind_addresses` in the above is important: it ensures that access to the
+manhole is only possible for local users).
+
+Note that this will give administrative access to synapse to **all users** with
+shell access to the server. It should therefore **not** be enabled in
+environments where untrusted users have shell access.
+
+Then restart synapse, and point an ssh client at port 9000 on localhost, using
+the username `matrix`:
+
+```bash
+ssh -p9000 matrix@localhost
+```
+
+The password is `rabbithole`.
+
+This gives a Python REPL in which `hs` gives access to the
+`synapse.server.HomeServer` object - which in turn gives access to many other
+parts of the process.
+
+As a simple example, retrieving an event from the database:
+
+```
+>>> hs.get_datastore().get_event('$1416420717069yeQaw:matrix.org')

+Password auth provider modules
+==============================
+
+Password auth providers offer a way for server administrators to integrate
+their Synapse installation with an existing authentication system.
+
+A password auth provider is a Python class which is dynamically loaded into
+Synapse, and provides a number of methods by which it can integrate with the
+authentication system.
+
+This document serves as a reference for those looking to implement their own
+password auth providers.
+
+Required methods
+----------------
+
+Password auth provider classes must provide the following methods:
+
+*class* ``SomeProvider.parse_config``\(*config*)
+
+    This method is passed the ``config`` object for this module from the
+    homeserver configuration file.
+
+    It should perform any appropriate sanity checks on the provided
+    configuration, and return an object which is then passed into ``__init__``.
+
+*class* ``SomeProvider``\(*config*, *account_handler*)
+
+    The constructor is passed the config object returned by ``parse_config``,
+    and a ``synapse.module_api.ModuleApi`` object which allows the
+    password provider to check if accounts exist and/or create new ones.
+
+Optional methods
+----------------
+
+Password auth provider classes may optionally provide the following methods.
+
+*class* ``SomeProvider.get_db_schema_files``\()
+
+    This method, if implemented, should return an Iterable of ``(name,
+    stream)`` pairs of database schema files. Each file is applied in turn at
+    initialisation, and a record is then made in the database so that it is
+    not re-applied on the next start.
+
+``someprovider.get_supported_login_types``\()
+
+    This method, if implemented, should return a ``dict`` mapping from a login
+    type identifier (such as ``m.login.password``) to an iterable giving the
+    fields which must be provided by the user in the submission to the
+    ``/login`` api. These fields are passed in the ``login_dict`` dictionary
+    to ``check_auth``.
+
+    For example, if a password auth provider wants to implement a custom login
+    type of ``com.example.custom_login``, where the client is expected to pass
+    the fields ``secret1`` and ``secret2``, the provider should implement this
+    method and return the following dict::
+
+      {"com.example.custom_login": ("secret1", "secret2")}
+
+``someprovider.check_auth``\(*username*, *login_type*, *login_dict*)
+
+    This method is the one that does the real work. If implemented, it will be
+    called for each login attempt where the login type matches one of the keys
+    returned by ``get_supported_login_types``.
+
+    It is passed the (possibly UNqualified) ``user`` provided by the client,
+    the login type, and a dictionary of login secrets passed by the client.
+
+    The method should return a Twisted ``Deferred`` object, which resolves to
+    the canonical ``@localpart:domain`` user id if authentication is successful,
+    and ``None`` if not.
+

+Server Notices
+==============
+
+'Server Notices' are a new feature introduced in Synapse 0.30. They provide a
+channel whereby server administrators can send messages to users on the server.
+
+They are used as part of communication of the server polices(see
+[consent_tracking.md](consent_tracking.md)), however the intention is that
+they may also find a use for features such as "Message of the day".
+
+This is a feature specific to Synapse, but it uses standard Matrix
+communication mechanisms, so should work with any Matrix client.
+
+User experience
+---------------
+
+When the user is first sent a server notice, they will get an invitation to a
+room (typically called 'Server Notices', though this is configurable in
+`homeserver.yaml`). They will be **unable to reject** this invitation -
+attempts to do so will receive an error.
+
+Once they accept the invitation, they will see the notice message in the room
+history; it will appear to have come from the 'server notices user' (see
+below).
+
+The user is prevented from sending any messages in this room by the power
+levels.
+
+Having joined the room, the user can leave the room if they want. Subsequent
+server notices will then cause a new room to be created.
+
+Synapse configuration
+---------------------
+
+Server notices come from a specific user id on the server. Server
+administrators are free to choose the user id - something like `server` is
+suggested, meaning the notices will come from
+`@server:<your_server_name>`. Once the Server Notices user is configured, that
+user id becomes a special, privileged user, so administrators should ensure
+that **it is not already allocated**.
+
+In order to support server notices, it is necessary to add some configuration
+to the `homeserver.yaml` file. In particular, you should add a `server_notices`
+section, which should look like this:
+
+```yaml
+server_notices:
+   system_mxid_localpart: server
+   system_mxid_display_name: "Server Notices"
+   system_mxid_avatar_url: "mxc://server.com/oumMVlgDnLYFaPVkExemNVVZ"
+   room_name: "Server Notices"
+```
+
+The only compulsory setting is `system_mxid_localpart`, which defines the user
+id of the Server Notices user, as above. `room_name` defines the name of the
+room which will be created.
+
+`system_mxid_display_name` and `system_mxid_avatar_url` can be used to set the
+displayname and avatar of the Server Notices user.
+
+Sending notices
+---------------
+
+As of the current version of synapse, there is no convenient interface for
+sending notices (other than the automated ones sent as part of consent
+tracking).
+
+In the meantime, it is possible to test this feature using the manhole. Having
+gone into the manhole as described in [manhole.md](manhole.md), a notice can be
+sent with something like:
+
+```
+>>> hs.get_server_notices_manager().send_notice('@user:server.com', {'msgtype':'m.text', 'body':'foo'})
+```

+User Directory API Implementation
+=================================

+The user directory is currently maintained based on the 'visible' users
+on this particular server - i.e. ones which your account shares a room with, or

+
+The directory info is stored in various tables, which can (typically after

 Scaling synapse via workers

 Synapse has experimental support for splitting out functionality into
 multiple separate python processes, helping greatly with scalability.  These
 processes are called 'workers', and are (eventually) intended to scale

+Configuration
+-------------
+
+To make effective use of the workers, you will need to configure an HTTP

+``synapse.app.pusher``
+~~~~~~~~~~~~~~~~~~~~~~
+
+Handles sending push notifications to sygnal and email. Doesn't handle any
+REST endpoints itself, but you should set ``start_pushers: False`` in the
+shared configuration file to stop the main synapse sending these notifications.
+
+Note this worker cannot be load-balanced: only one instance should be active.
+
+``synapse.app.synchrotron``

+
+The synchrotron handles ``sync`` requests from clients. In particular, it can
+handle REST endpoints matching the following regular expressions::
+
+    ^/_matrix/client/(v2_alpha|r0)/sync$
+    ^/_matrix/client/(api/v1|v2_alpha|r0)/events$
+    ^/_matrix/client/(api/v1|r0)/initialSync$
+    ^/_matrix/client/(api/v1|r0)/rooms/[^/]+/initialSync$
+
+The above endpoints should all be routed to the synchrotron worker by the
+reverse-proxy configuration.
+
+It is possible to run multiple instances of the synchrotron to scale
+horizontally. In this case the reverse-proxy should be configured to
+load-balance across the instances, though it will be more efficient if all
+requests from a particular user are routed to a single instance. Extracting
+a userid from the access token is currently left as an exercise for the reader.
+
+``synapse.app.appservice``
+~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Handles sending output traffic to Application Services. Doesn't handle any
+REST endpoints itself, but you should set ``notify_appservices: False`` in the
+shared configuration file to stop the main synapse sending these notifications.
+
+Note this worker cannot be load-balanced: only one instance should be active.
+
+``synapse.app.federation_reader``
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Handles a subset of federation endpoints. In particular, it can handle REST
+endpoints matching the following regular expressions::
+
+    ^/_matrix/federation/v1/event/
+    ^/_matrix/federation/v1/state/

+    ^/_matrix/federation/v1/publicRooms
+
+The above endpoints should all be routed to the federation_reader worker by the
+reverse-proxy configuration.
+
+``synapse.app.federation_sender``
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Handles sending federation traffic to other servers. Doesn't handle any
+REST endpoints itself, but you should set ``send_federation: False`` in the
+shared configuration file to stop the main synapse sending this traffic.
+
+Note this worker cannot be load-balanced: only one instance should be active.
+
+``synapse.app.media_repository``
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Handles the media repository. It can handle all endpoints starting with::
+
+    /_matrix/media/
+
+You should also set ``enable_media_repo: False`` in the shared configuration
+file to stop the main synapse running background jobs related to managing the
+media repository.
+
+Note this worker cannot be load-balanced: only one instance should be active.
+
+``synapse.app.client_reader``
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Handles client API endpoints. It can handle REST endpoints matching the
+following regular expressions::

+    ^/_matrix/client/(api/v1|r0|unstable)/publicRooms$
+    ^/_matrix/client/(api/v1|r0|unstable)/rooms/.*/joined_members$

+
+Handles searches in the user directory. It can handle REST endpoints matching
+the following regular expressions::
+
+    ^/_matrix/client/(api/v1|r0|unstable)/user_directory/search$
+
+``synapse.app.frontend_proxy``
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Proxies some frequently-requested client endpoints to add caching and remove
+load from the main synapse. It can handle REST endpoints matching the following
+regular expressions::
+
+    ^/_matrix/client/(api/v1|r0|unstable)/keys/upload
+
+It will proxy any requests it cannot handle to the main synapse instance. It
+must therefore be configured with the location of the main instance, via
+the ``worker_main_http_uri`` setting in the frontend_proxy worker configuration
+file. For example::
+
+    worker_main_http_uri: http://127.0.0.1:8008
+
+
+``synapse.app.event_creator``
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Handles some event creation. It can handle REST endpoints matching::

+    ^/_matrix/client/(api/v1|r0|unstable)/rooms/.*/send
+    ^/_matrix/client/(api/v1|r0|unstable)/rooms/.*/(join|invite|leave|ban|unban|kick)$
+    ^/_matrix/client/(api/v1|r0|unstable)/join/
+
+It will create events locally and then send them on to the main synapse
