-Synapse 1.13.0rc2 (2020-05-14)
-==============================
-
-Bugfixes
---------
-
-- Fix a long-standing bug which could cause messages not to be sent over federation, when state events with state keys matching user IDs (such as custom user statuses) were received. ([\#7376](https://github.com/matrix-org/synapse/issues/7376))
-- Restore compatibility with non-compliant clients during the user interactive authentication process, fixing a problem introduced in v1.13.0rc1. ([\#7483](https://github.com/matrix-org/synapse/issues/7483))
-
-Internal Changes
-----------------
-
-- Fix linting errors in new version of Flake8. ([\#7470](https://github.com/matrix-org/synapse/issues/7470))

-
-Synapse 1.13.0rc1 (2020-05-11)
-==============================
-
-This release brings some potential changes necessary for certain
-configurations of Synapse:
-
-* If your Synapse is configured to use SSO and have a custom
-  `sso_redirect_confirm_template_dir` configuration option set, you will need
-  to duplicate the new `sso_auth_confirm.html`, `sso_auth_success.html` and
-  `sso_account_deactivated.html` templates into that directory.
-* Synapse plugins using the `complete_sso_login` method of
-  `synapse.module_api.ModuleApi` should instead switch to the async/await
-  version, `complete_sso_login_async`, which includes additional checks. The
-  former version is now deprecated.
-* A bug was introduced in Synapse 1.4.0 which could cause the room directory
-  to be incomplete or empty if Synapse was upgraded directly from v1.2.1 or
-  earlier, to versions between v1.4.0 and v1.12.x.
-
-Please review [UPGRADE.rst](UPGRADE.rst) for more details on these changes
-and for general upgrade guidance.

-
-Synapse 1.12.0 (2020-03-23)
-===========================
-
-Debian packages and Docker images are rebuilt using the latest versions of
-dependency libraries, including Twisted 20.3.0. **Please see security advisory
-below**.
-
-Potential slow database update during upgrade
----------------------------------------------
-
-Synapse 1.12.0 includes a database update which is run as part of the upgrade,
-and which may take some time (several hours in the case of a large
-server). Synapse will not respond to HTTP requests while this update is taking
-place. For imformation on seeing if you are affected, and workaround if you
-are, see the [upgrade notes](UPGRADE.rst#upgrading-to-v1120).
-
-Security advisory
------------------
-
-Synapse may be vulnerable to request-smuggling attacks when it is used with a
-reverse-proxy. The vulnerabilties are fixed in Twisted 20.3.0, and are
-described in
-[CVE-2020-10108](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2020-10108)
-and
-[CVE-2020-10109](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2020-10109).
-For a good introduction to this class of request-smuggling attacks, see
-https://portswigger.net/research/http-desync-attacks-request-smuggling-reborn.
-
-We are not aware of these vulnerabilities being exploited in the wild, and
-do not believe that they are exploitable with current versions of any reverse
-proxies. Nevertheless, we recommend that all Synapse administrators ensure that
-they have the latest versions of the Twisted library to ensure that their
-installation remains secure.
-
-* Administrators using the [`matrix.org` Docker
-  image](https://hub.docker.com/r/matrixdotorg/synapse/) or the [Debian/Ubuntu
-  packages from
-  `matrix.org`](https://github.com/matrix-org/synapse/blob/master/INSTALL.md#matrixorg-packages)
-  should ensure that they have version 1.12.0 installed: these images include
-  Twisted 20.3.0.
-* Administrators who have [installed Synapse from
-  source](https://github.com/matrix-org/synapse/blob/master/INSTALL.md#installing-from-source)
-  should upgrade Twisted within their virtualenv by running:
-  ```sh
-  <path_to_virtualenv>/bin/pip install 'Twisted>=20.3.0'
-  ```
-* Administrators who have installed Synapse from distribution packages should
-  consult the information from their distributions.
-
-The `matrix.org` Synapse instance was not vulnerable to these vulnerabilities.
-
-Advance notice of change to the default `git` branch for Synapse
-----------------------------------------------------------------
-
-Currently, the default `git` branch for Synapse is `master`, which tracks the
-latest release.
-
-After the release of Synapse 1.13.0, we intend to change this default to
-`develop`, which is the development tip. This is more consistent with common
-practice and modern `git` usage.
-
-Although we try to keep `develop` in a stable state, there may be occasions
-where regressions creep in. Developers and distributors who have scripts which
-run builds using the default branch of `Synapse` should therefore consider
-pinning their scripts to `master`.

-## Merge Strategy
-
-We use the commit history of develop/master extensively to identify
-when regressions were introduced and what changes have been made.
-
-We aim to have a clean merge history, which means we normally squash-merge
-changes into develop. For small changes this means there is no need to rebase
-to clean up your PR before merging. Larger changes with an organised set of
-commits may be merged as-is, if the history is judged to be useful.
-
-This use of squash-merging will mean PRs built on each other will be hard to 
-merge. We suggest avoiding these where possible, and if required, ensuring
-each PR has a tidy set of commits to ease merging.
-
 ## Conclusion
 
 That's it! Matrix is a very open and collaborative project as you might expect

+### Troubleshooting Installation
+
+XXX a bunch of this is no longer relevant.
+
+Synapse requires pip 8 or later, so if your OS provides too old a version you
+may need to manually upgrade it::
+
+    sudo pip install --upgrade pip
+
+Installing may fail with `Could not find any downloads that satisfy the requirement pymacaroons-pynacl (from matrix-synapse==0.12.0)`.
+You can fix this by manually upgrading pip and virtualenv::
+
+    sudo pip install --upgrade virtualenv
+
+You can next rerun `virtualenv -p python3 synapse` to update the virtual env.
+
+Installing may fail during installing virtualenv with `InsecurePlatformWarning: A true SSLContext object is not available. This prevents urllib3 from configuring SSL appropriately and may cause certain SSL connections to fail. For more information, see https://urllib3.readthedocs.org/en/latest/security.html#insecureplatformwarning.`
+You can fix this  by manually installing ndg-httpsclient::
+
+    pip install --upgrade ndg-httpsclient
+
+Installing may fail with `mock requires setuptools>=17.1. Aborting installation`.
+You can fix this by upgrading setuptools::
+
+    pip install --upgrade setuptools
+
+If pip crashes mid-installation for reason (e.g. lost terminal), pip may
+refuse to run until you remove the temporary installation directory it
+created. To reset the installation::
+
+    rm -rf /tmp/pip_install_matrix
+
+pip seems to leak *lots* of memory during installation.  For instance, a Linux
+host with 512MB of RAM may run out of memory whilst installing Twisted.  If this
+happens, you will have to individually install the dependencies which are
+failing, e.g.::

-Upgrading to v1.13.0
-====================
-
-
-Incorrect database migration in old synapse versions
-----------------------------------------------------
-
-A bug was introduced in Synapse 1.4.0 which could cause the room directory to
-be incomplete or empty if Synapse was upgraded directly from v1.2.1 or
-earlier, to versions between v1.4.0 and v1.12.x.
-
-This will *not* be a problem for Synapse installations which were:
- * created at v1.4.0 or later,
- * upgraded via v1.3.x, or
- * upgraded straight from v1.2.1 or earlier to v1.13.0 or later.
-
-If completeness of the room directory is a concern, installations which are
-affected can be repaired as follows:
-
-1. Run the following sql from a `psql` or `sqlite3` console:
-
-   .. code:: sql
-
-     INSERT INTO background_updates (update_name, progress_json, depends_on) VALUES
-        ('populate_stats_process_rooms', '{}', 'current_state_events_membership');
-
-     INSERT INTO background_updates (update_name, progress_json, depends_on) VALUES
-        ('populate_stats_process_users', '{}', 'populate_stats_process_rooms');
-
-2. Restart synapse.
-
-New Single Sign-on HTML Templates
----------------------------------
-
-New templates (``sso_auth_confirm.html``, ``sso_auth_success.html``, and
-``sso_account_deactivated.html``) were added to Synapse. If your Synapse is
-configured to use SSO and a custom  ``sso_redirect_confirm_template_dir``
-configuration then these templates will need to be copied from
-`synapse/res/templates <synapse/res/templates>`_ into that directory.
-
-Synapse SSO Plugins Method Deprecation
---------------------------------------
-
-Plugins using the ``complete_sso_login`` method of
-``synapse.module_api.ModuleApi`` should update to using the async/await
-version ``complete_sso_login_async`` which includes additional checks. The
-non-async version is considered deprecated.
-
-Rolling back to v1.12.4 after a failed upgrade
-----------------------------------------------
-
-v1.13.0 includes a lot of large changes. If something problematic occurs, you
-may want to roll-back to a previous version of Synapse. Because v1.13.0 also
-includes a new database schema version, reverting that version is also required
-alongside the generic rollback instructions mentioned above. In short, to roll
-back to v1.12.4 you need to:
-
-1. Stop the server
-2. Decrease the schema version in the database:
-
-   .. code:: sql
-    
-      UPDATE schema_version SET version = 57;
-
-3. Downgrade Synapse by following the instructions for your installation method
-   in the "Rolling back to older versions" section above.
-    
-
-Upgrading to v1.12.0
-====================
-
-This version includes a database update which is run as part of the upgrade,
-and which may take some time (several hours in the case of a large
-server). Synapse will not respond to HTTP requests while this update is taking
-place.
-
-This is only likely to be a problem in the case of a server which is
-participating in many rooms.
-
-0. As with all upgrades, it is recommended that you have a recent backup of
-   your database which can be used for recovery in the event of any problems.
-
-1. As an initial check to see if you will be affected, you can try running the
-   following query from the `psql` or `sqlite3` console. It is safe to run it
-   while Synapse is still running.
-
-   .. code:: sql
-
-      SELECT MAX(q.v) FROM (
-        SELECT (
-          SELECT ej.json AS v
-          FROM state_events se INNER JOIN event_json ej USING (event_id)
-          WHERE se.room_id=rooms.room_id AND se.type='m.room.create' AND se.state_key=''
-          LIMIT 1
-        ) FROM rooms WHERE rooms.room_version IS NULL
-      ) q;
-
-   This query will take about the same amount of time as the upgrade process: ie,
-   if it takes 5 minutes, then it is likely that Synapse will be unresponsive for
-   5 minutes during the upgrade.
-
-   If you consider an outage of this duration to be acceptable, no further
-   action is necessary and you can simply start Synapse 1.12.0.
-
-   If you would prefer to reduce the downtime, continue with the steps below.
-
-2. The easiest workaround for this issue is to manually
-   create a new index before upgrading. On PostgreSQL, his can be done as follows:
-
-   .. code:: sql
-
-      CREATE INDEX CONCURRENTLY tmp_upgrade_1_12_0_index
-      ON state_events(room_id) WHERE type = 'm.room.create';
-
-   The above query may take some time, but is also safe to run while Synapse is
-   running.
-
-   We assume that no SQLite users have databases large enough to be
-   affected. If you *are* affected, you can run a similar query, omitting the
-   ``CONCURRENTLY`` keyword. Note however that this operation may in itself cause
-   Synapse to stop running for some time. Synapse admins are reminded that
-   `SQLite is not recommended for use outside a test
-   environment <https://github.com/matrix-org/synapse/blob/master/README.rst#using-postgresql>`_.
-
-3. Once the index has been created, the ``SELECT`` query in step 1 above should
-   complete quickly. It is therefore safe to upgrade to Synapse 1.12.0.
-
-4. Once Synapse 1.12.0 has successfully started and is responding to HTTP
-   requests, the temporary index can be removed:
-
-   .. code:: sql
-
-      DROP INDEX tmp_upgrade_1_12_0_index;
-
-Upgrading to v1.10.0
-====================
-
-Synapse will now log a warning on start up if used with a PostgreSQL database
-that has a non-recommended locale set.
-
-See `docs/postgres.md <docs/postgres.md>`_ for details.
-
-
-Upgrading to v1.8.0
-===================
-
-Specifying a ``log_file`` config option will now cause Synapse to refuse to
-start, and should be replaced by with the ``log_config`` option. Support for
-the ``log_file`` option was removed in v1.3.0 and has since had no effect.
-
-

-The documentation for using systemd to manage synapse workers is now part of
-the main synapse distribution. See [docs/systemd-with-workers](../../docs/systemd-with-workers).
+# Setup Synapse with Workers and Systemd
+
+This is a setup for managing synapse with systemd including support for
+managing workers. It provides a `matrix-synapse`, as well as a
+`matrix-synapse-worker@` service for any workers you require. Additionally to
+group the required services it sets up a `matrix.target`. You can use this to
+automatically start any bot- or bridge-services. More on this in
+[Bots and Bridges](#bots-and-bridges).
+
+See the folder [system](system) for any service and target files.
+
+The folder [workers](workers) contains an example configuration for the
+`federation_reader` worker. Pay special attention to the name of the
+configuration file. In order to work with the `matrix-synapse-worker@.service`
+service, it needs to have the exact same name as the worker app.
+
+This setup expects neither the homeserver nor any workers to fork. Forking is
+handled by systemd.
+
+## Setup
+
+1. Adjust your matrix configs. Make sure that the worker config files have the
+exact same name as the worker app. Compare `matrix-synapse-worker@.service` for
+why. You can find an example worker config in the [workers](workers) folder. See
+below for relevant settings in the `homeserver.yaml`.
+2. Copy the `*.service` and `*.target` files in [system](system) to
+`/etc/systemd/system`.
+3. `systemctl enable matrix-synapse.service` this adds the homeserver
+app to the `matrix.target`
+4. *Optional.* `systemctl enable
+matrix-synapse-worker@federation_reader.service` this adds the federation_reader
+app to the `matrix-synapse.service`
+5. *Optional.* Repeat step 4 for any additional workers you require.
+6. *Optional.* Add any bots or bridges by enabling them.
+7. Start all matrix related services via `systemctl start matrix.target`
+8. *Optional.* Enable autostart of all matrix related services on system boot
+via `systemctl enable matrix.target`
+
+## Usage
+
+After you have setup you can use the following commands to manage your synapse
+installation:
+
+```
+# Start matrix-synapse, all workers and any enabled bots or bridges.
+systemctl start matrix.target
+
+# Restart matrix-synapse and all workers (not necessarily restarting bots
+# or bridges, see "Bots and Bridges")
+systemctl restart matrix-synapse.service
+
+# Stop matrix-synapse and all workers (not necessarily restarting bots
+# or bridges, see "Bots and Bridges")
+systemctl stop matrix-synapse.service
+
+# Restart a specific worker (i. e. federation_reader), the homeserver is
+# unaffected by this.
+systemctl restart matrix-synapse-worker@federation_reader.service
+
+# Add a new worker (assuming all configs are setup already)
+systemctl enable matrix-synapse-worker@federation_writer.service
+systemctl restart matrix-synapse.service
+```
+
+## The Configs
+
+Make sure the `worker_app` is set in the `homeserver.yaml` and it does not fork.
+
+```
+worker_app: synapse.app.homeserver 
+daemonize: false
+```
+
+None of the workers should fork, as forking is handled by systemd. Hence make
+sure this is present in all worker config files.
+
+```
+worker_daemonize: false
+```
+
+The config files of all workers are expected to be located in
+`/etc/matrix-synapse/workers`. If you want to use a different location you have
+to edit the provided `*.service` files accordingly.  
+
+## Bots and Bridges
+
+Most bots and bridges do not care if the homeserver goes down or is restarted.
+Depending on the implementation this may crash them though. So look up the docs
+or ask the community of the specific bridge or bot you want to run to make sure
+you choose the correct setup.
+
+Whichever configuration you choose, after the setup the following will enable
+automatically starting (and potentially restarting) your bot/bridge with the
+`matrix.target`.
+
+```
+systemctl enable <yourBotOrBridgeName>.service
+```
+
+**Note** that from an inactive synapse the bots/bridges will only be started with
+synapse if you start the `matrix.target`, not if you start the
+`matrix-synapse.service`. This is on purpose. Think of `matrix-synapse.service`
+as *just* synapse, but `matrix.target` being anything matrix related, including
+synapse and any and all enabled bots and bridges.
+
+### Start with synapse but ignore synapse going down
+
+If the bridge can handle shutdowns of the homeserver you'll want to install the
+service in the `matrix.target` and optionally add a
+`After=matrix-synapse.service` dependency to have the bot/bridge start after
+synapse on starting everything.
+
+In this case the service file should look like this.
+
+```
+[Unit]
+# ...
+# Optional, this will only ensure that if you start everything, synapse will
+# be started before the bot/bridge will be started.
+After=matrix-synapse.service
+
+[Service]
+# ...
+
+[Install]
+WantedBy=matrix.target
+```
+
+### Stop/restart when synapse stops/restarts
+
+If the bridge can't handle shutdowns of the homeserver you'll still want to
+install the service in the `matrix.target` but also have to specify the
+`After=matrix-synapse.service` *and* `BindsTo=matrix-synapse.service`
+dependencies to have the bot/bridge stop/restart with synapse.
+
+In this case the service file should look like this.
+
+```
+[Unit]
+# ...
+# Mandatory
+After=matrix-synapse.service
+BindsTo=matrix-synapse.service
+
+[Service]
+# ...
+
+[Install]
+WantedBy=matrix.target
+```

 # 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, and for existing accounts in June 2020.
-
-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 2020.
-* 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.

+will provision server-to-server certificates automatically for you for free

-# List Room API
-
-The List Room admin API allows server admins to get a list of rooms on their
-server. There are various parameters available that allow for filtering and
-sorting the returned list. This API supports pagination.
-
-## Parameters
-
-The following query parameters are available:
-
-* `from` - Offset in the returned list. Defaults to `0`.
-* `limit` - Maximum amount of rooms to return. Defaults to `100`.
-* `order_by` - The method in which to sort the returned list of rooms. Valid values are:
-  - `alphabetical` - Same as `name`. This is deprecated.
-  - `size` - Same as `joined_members`. This is deprecated.
-  - `name` - Rooms are ordered alphabetically by room name. This is the default.
-  - `canonical_alias` - Rooms are ordered alphabetically by main alias address of the room.
-  - `joined_members` - Rooms are ordered by the number of members. Largest to smallest.
-  - `joined_local_members` - Rooms are ordered by the number of local members. Largest to smallest.
-  - `version` - Rooms are ordered by room version. Largest to smallest.
-  - `creator` - Rooms are ordered alphabetically by creator of the room.
-  - `encryption` - Rooms are ordered alphabetically by the end-to-end encryption algorithm.
-  - `federatable` - Rooms are ordered by whether the room is federatable.
-  - `public` - Rooms are ordered by visibility in room list.
-  - `join_rules` - Rooms are ordered alphabetically by join rules of the room.
-  - `guest_access` - Rooms are ordered alphabetically by guest access option of the room.
-  - `history_visibility` - Rooms are ordered alphabetically by visibility of history of the room.
-  - `state_events` - Rooms are ordered by number of state events. Largest to smallest.
-* `dir` - Direction of room order. Either `f` for forwards or `b` for backwards. Setting
-          this value to `b` will reverse the above sort order. Defaults to `f`.
-* `search_term` - Filter rooms by their room name. Search term can be contained in any
-                  part of the room name. Defaults to no filtering.
-
-The following fields are possible in the JSON response body:
-
-* `rooms` - An array of objects, each containing information about a room.
-  - Room objects contain the following fields:
-    - `room_id` - The ID of the room.
-    - `name` - The name of the room.
-    - `canonical_alias` - The canonical (main) alias address of the room.
-    - `joined_members` - How many users are currently in the room.
-    - `joined_local_members` - How many local users are currently in the room.
-    - `version` - The version of the room as a string.
-    - `creator` - The `user_id` of the room creator.
-    - `encryption` - Algorithm of end-to-end encryption of messages. Is `null` if encryption is not active.
-    - `federatable` - Whether users on other servers can join this room.
-    - `public` - Whether the room is visible in room directory.
-    - `join_rules` - The type of rules used for users wishing to join this room. One of: ["public", "knock", "invite", "private"].
-    - `guest_access` - Whether guests can join the room. One of: ["can_join", "forbidden"].
-    - `history_visibility` - Who can see the room history. One of: ["invited", "joined", "shared", "world_readable"].
-    - `state_events` - Total number of state_events of a room. Complexity of the room.
-* `offset` - The current pagination offset in rooms. This parameter should be
-             used instead of `next_token` for room offset as `next_token` is
-             not intended to be parsed.
-* `total_rooms` - The total number of rooms this query can return. Using this
-                  and `offset`, you have enough information to know the current
-                  progression through the list.
-* `next_batch` - If this field is present, we know that there are potentially
-                 more rooms on the server that did not all fit into this response.
-                 We can use `next_batch` to get the "next page" of results. To do
-                 so, simply repeat your request, setting the `from` parameter to
-                 the value of `next_batch`.
-* `prev_batch` - If this field is present, it is possible to paginate backwards.
-                 Use `prev_batch` for the `from` value in the next request to
-                 get the "previous page" of results.

-# Delegation
-
-By default, other homeservers will expect to be able to reach yours via
-your `server_name`, on port 8448. For example, if you set your `server_name`
-to `example.com` (so that your user names look like `@user:example.com`),
-other servers will try to connect to yours at `https://example.com:8448/`.
-
-Delegation is a Matrix feature allowing a homeserver admin to retain a
-`server_name` of `example.com` so that user IDs, room aliases, etc continue
-to look like `*:example.com`, whilst having federation traffic routed
-to a different server and/or port (e.g. `synapse.example.com:443`).
-
-## .well-known delegation
-
-To use this method, you need to be able to alter the
-`server_name` 's https server to serve the `/.well-known/matrix/server`
-URL. Having an active server (with a valid TLS certificate) serving your
-`server_name` domain is out of the scope of this documentation.
-
-The URL `https://<server_name>/.well-known/matrix/server` should
-return a JSON structure containing the key `m.server` like so:
-
-```json
-{
-    "m.server": "<synapse.server.name>[:<yourport>]"
-}
-```
-
-In our example, this would mean that URL `https://example.com/.well-known/matrix/server`
-should return:
-
-```json
-{
-    "m.server": "synapse.example.com:443"
-}
-```
-
-Note, specifying a port is optional. If no port is specified, then it defaults
-to 8448.
-
-With .well-known delegation, federating servers will check for a valid TLS
-certificate for the delegated hostname (in our example: `synapse.example.com`).
-
-## SRV DNS record delegation
-
-It is also possible to do delegation using a SRV DNS record. However, that is
-considered an advanced topic since it's a bit complex to set up, and `.well-known`
-delegation is already enough in most cases.
-
-However, if you really need it, you can find some documentation on how such a
-record should look like and how Synapse will use it in [the Matrix
-specification](https://matrix.org/docs/spec/server_server/latest#resolving-server-names).
-
-## Delegation FAQ
-
-### When do I need delegation?
-
-If your homeserver's APIs are accessible on the default federation port (8448)
-and the domain your `server_name` points to, you do not need any delegation.
-
-For instance, if you registered `example.com` and pointed its DNS A record at a
-fresh server, you could install Synapse on that host, giving it a `server_name`
-of `example.com`, and once a reverse proxy has been set up to proxy all requests
-sent to the port `8448` and serve TLS certificates for `example.com`, you
-wouldn't need any delegation set up.
-
-**However**, if your homeserver's APIs aren't accessible on port 8448 and on the
-domain `server_name` points to, you will need to let other servers know how to
-find it using delegation.
-
-### Do you still recommend against using a reverse proxy on the federation port?
-
-We no longer actively recommend against using a reverse proxy. Many admins will
-find it easier to direct federation traffic to a reverse proxy and manage their
-own TLS certificates, and this is a supported configuration.
-
-See [reverse_proxy.md](reverse_proxy.md) for information on setting up a
-reverse proxy.
-
-### Do I still need to give my TLS certificates to Synapse if I am using a reverse proxy?
-
-This is no longer necessary. If you are using a reverse proxy for all of your
-TLS traffic, then you can set `no_tls: True` in the Synapse config.
-
-In that case, the only reason Synapse needs the certificate is to populate a legacy
-`tls_fingerprints` field in the federation API. This is ignored by Synapse 0.99.0
-and later, and the only time pre-0.99 Synapses will check it is when attempting to
-fetch the server keys - and generally this is delegated via `matrix.org`, which
-is running a modern version of Synapse.
-
-### Do I need the same certificate for the client and federation port?
-
-No. There is nothing stopping you from using different certificates,
-particularly if you are using a reverse proxy.

-# How to test CAS as a developer without a server
-
-The [django-mama-cas](https://github.com/jbittel/django-mama-cas) project is an
-easy to run CAS implementation built on top of Django.
-
-## Prerequisites
-
-1. Create a new virtualenv: `python3 -m venv <your virtualenv>`
-2. Activate your virtualenv: `source /path/to/your/virtualenv/bin/activate`
-3. Install Django and django-mama-cas:
-   ```
-   python -m pip install "django<3" "django-mama-cas==2.4.0"
-   ```
-4. Create a Django project in the current directory:
-   ```
-   django-admin startproject cas_test .
-   ```
-5. Follow the [install directions](https://django-mama-cas.readthedocs.io/en/latest/installation.html#configuring) for django-mama-cas
-6. Setup the SQLite database: `python manage.py migrate`
-7. Create a user:
-   ```
-   python manage.py createsuperuser
-   ```
-   1. Use whatever you want as the username and password.
-   2. Leave the other fields blank.
-8. Use the built-in Django test server to serve the CAS endpoints on port 8000:
-   ```
-   python manage.py runserver
-   ```
-
-You should now have a Django project configured to serve CAS authentication with
-a single user created.
-
-## Configure Synapse (and Riot) to use CAS
-
-1. Modify your `homeserver.yaml` to enable CAS and point it to your locally
-   running Django test server:
-   ```yaml
-   cas_config:
-     enabled: true
-     server_url: "http://localhost:8000"
-     service_url: "http://localhost:8081"
-     #displayname_attribute: name
-     #required_attributes:
-     #    name: value
-   ```
-2. Restart Synapse.
-
-Note that the above configuration assumes the homeserver is running on port 8081
-and that the CAS server is on port 8000, both on localhost.
-
-## Testing the configuration
-
-Then in Riot:
-
-1. Visit the login page with a Riot pointing at your homeserver.
-2. Click the Single Sign-On button.
-3. Login using the credentials created with `createsuperuser`.
-4. You should be logged in.
-
-If you want to repeat this process you'll need to manually logout first:
-
-1. http://localhost:8000/admin/
-2. Click "logout" in the top right.

-# How to test OpenID Connect
-
-Any OpenID Connect Provider (OP) should work with Synapse, as long as it supports the authorization code flow.
-There are a few options for that:
-
- - start a local OP. Synapse has been tested with [Hydra][hydra] and [Dex][dex-idp].
-   Note that for an OP to work, it should be served under a secure (HTTPS) origin.
-   A certificate signed with a self-signed, locally trusted CA should work. In that case, start Synapse with a `SSL_CERT_FILE` environment variable set to the path of the CA.
- - use a publicly available OP. Synapse has been tested with [Google][google-idp].
- - setup a SaaS OP, like [Auth0][auth0] and [Okta][okta]. Auth0 has a free tier which has been tested with Synapse.

-## Sample configs
-
-Here are a few configs for providers that should work with Synapse.
-
-### [Dex][dex-idp]
-
-[Dex][dex-idp] is a simple, open-source, certified OpenID Connect Provider.
-Although it is designed to help building a full-blown provider, with some external database, it can be configured with static passwords in a config file.
-
-Follow the [Getting Started guide](https://github.com/dexidp/dex/blob/master/Documentation/getting-started.md) to install Dex.
-
-Edit `examples/config-dev.yaml` config file from the Dex repo to add a client:
-
-```yaml
-staticClients:
-- id: synapse
-  secret: secret
-  redirectURIs:
-  - '[synapse base url]/_synapse/oidc/callback'
-  name: 'Synapse'
-```
-
-Run with `dex serve examples/config-dex.yaml`
-
-Synapse config:
-
-```yaml
-oidc_config:
-   enabled: true
-   skip_verification: true # This is needed as Dex is served on an insecure endpoint
-   issuer: "http://127.0.0.1:5556/dex"
-   discover: true
-   client_id: "synapse"
-   client_secret: "secret"
-   scopes:
-     - openid
-     - profile
-   user_mapping_provider:
-     config:
-       localpart_template: '{{ user.name }}'
-       display_name_template: '{{ user.name|capitalize }}'
-```
-
-### [Auth0][auth0]
-
-1. Create a regular web application for Synapse
-2. Set the Allowed Callback URLs to `[synapse base url]/_synapse/oidc/callback`
-3. Add a rule to add the `preferred_username` claim.

-### GitHub
-
-GitHub is a bit special as it is not an OpenID Connect compliant provider, but just a regular OAuth2 provider.
-The `/user` API endpoint can be used to retrieve informations from the user.
-As the OIDC login mechanism needs an attribute to uniquely identify users and that endpoint does not return a `sub` property, an alternative `subject_claim` has to be set.

-Setting up federation
+Setting up Federation
 =====================
 
 Federation is the process by which users on different servers can participate
 in the same room. For this to work, those other servers must be able to contact
 yours to send messages.
 
-The `server_name` configured in the Synapse configuration file (often
-`homeserver.yaml`) defines how resources (users, rooms, etc.) will be
-identified (eg: `@user:example.com`, `#room:example.com`). By default,
-it is also the domain that other servers will use to try to reach your
-server (via port 8448). This is easy to set up and will work provided
-you set the `server_name` to match your machine's public DNS hostname.
-
-For this default configuration to work, you will need to listen for TLS
-connections on port 8448. The preferred way to do that is by using a
-reverse proxy: see [reverse_proxy.md](<reverse_proxy.md>) for instructions
-on how to correctly set one up.
-
-In some cases you might not want to run Synapse on the machine that has
-the `server_name` as its public DNS hostname, or you might want federation
-traffic to use a different port than 8448. For example, you might want to
-have your user names look like `@user:example.com`, but you want to run
-Synapse on `synapse.example.com` on port 443. This can be done using
-delegation, which allows an admin to control where federation traffic should
-be sent. See [delegate.md](delegate.md) for instructions on how to set this up.
+The ``server_name`` configured in the Synapse configuration file (often
+``homeserver.yaml``) defines how resources (users, rooms, etc.) will be
+identified (eg: ``@user:example.com``, ``#room:example.com``). By
+default, it is also the domain that other servers will use to
+try to reach your server (via port 8448). This is easy to set
+up and will work provided you set the ``server_name`` to match your
+machine's public DNS hostname, and provide Synapse with a TLS certificate
+which is valid for your ``server_name``.
 
 Once federation has been configured, you should be able to join a room over
-federation. A good place to start is `#synapse:matrix.org` - a room for
+federation. A good place to start is ``#synapse:matrix.org`` - a room for
 Synapse admins.
 
+
+## Delegation
+
+For a more flexible configuration, you can have ``server_name``
+resources (eg: ``@user:example.com``) served by a different host and
+port (eg: ``synapse.example.com:443``). There are two ways to do this:
+
+- adding a ``/.well-known/matrix/server`` URL served on ``https://example.com``.
+- adding a DNS ``SRV`` record in the DNS zone of domain
+  ``example.com``.
+
+Without configuring delegation, the matrix federation will
+expect to find your server via ``example.com:8448``. The following methods
+allow you retain a `server_name` of `example.com` so that your user IDs, room
+aliases, etc continue to look like `*:example.com`, whilst having your
+federation traffic routed to a different server.
+
+### .well-known delegation
+
+To use this method, you need to be able to alter the
+``server_name`` 's https server to serve the ``/.well-known/matrix/server``
+URL. Having an active server (with a valid TLS certificate) serving your
+``server_name`` domain is out of the scope of this documentation.
+
+The URL ``https://<server_name>/.well-known/matrix/server`` should
+return a JSON structure containing the key ``m.server`` like so:
+
+    {
+	    "m.server": "<synapse.server.name>[:<yourport>]"
+    }
+
+In our example, this would mean that URL ``https://example.com/.well-known/matrix/server``
+should return:
+
+    {
+	    "m.server": "synapse.example.com:443"
+    }
+
+Note, specifying a port is optional. If a port is not specified an SRV lookup
+is performed, as described below. If the target of the
+delegation does not have an SRV record, then the port defaults to 8448.
+
+Most installations will not need to configure .well-known. However, it can be
+useful in cases where the admin is hosting on behalf of someone else and
+therefore cannot gain access to the necessary certificate. With .well-known,
+federation servers will check for a valid TLS certificate for the delegated
+hostname (in our example: ``synapse.example.com``).
+
+### DNS SRV delegation
+
+To use this delegation method, you need to have write access to your
+``server_name`` 's domain zone DNS records (in our example it would be
+``example.com`` DNS zone).
+
+This method requires the target server to provide a
+valid TLS certificate for the original ``server_name``.
+
+You need to add a SRV record in your ``server_name`` 's DNS zone with
+this format:
+
+     _matrix._tcp.<yourdomain.com> <ttl> IN SRV <priority> <weight> <port> <synapse.server.name>
+
+In our example, we would need to add this SRV record in the
+``example.com`` DNS zone:
+
+     _matrix._tcp.example.com. 3600 IN SRV 10 5 443 synapse.example.com.
+
+Once done and set up, you can check the DNS record with ``dig -t srv
+_matrix._tcp.<server_name>``. In our example, we would expect this:
+
+    $ dig -t srv _matrix._tcp.example.com
+    _matrix._tcp.example.com. 3600    IN      SRV     10 0 443 synapse.example.com.
+
+Note that the target of a SRV record cannot be an alias (CNAME record): it has to point
+directly to the server hosting the synapse instance.
+
+### Delegation FAQ
+#### When do I need a SRV record or .well-known URI?
+
+If your homeserver listens on the default federation port (8448), and your
+`server_name` points to the host that your homeserver runs on, you do not need an SRV
+record or `.well-known/matrix/server` URI.
+
+For instance, if you registered `example.com` and pointed its DNS A record at a
+fresh server, you could install Synapse on that host,
+giving it a `server_name` of `example.com`, and once [ACME](acme.md) support is enabled,
+it would automatically generate a valid TLS certificate for you via Let's Encrypt
+and no SRV record or .well-known URI would be needed.
+
+**However**, if your server does not listen on port 8448, or if your `server_name`
+does not point to the host that your homeserver runs on, you will need to let
+other servers know how to find it. The way to do this is via .well-known or an
+SRV record.
+
+#### I have created a .well-known URI. Do I also need an SRV record?
+
+No. You can use either `.well-known` delegation or use an SRV record for delegation. You
+do not need to use both to delegate to the same location.
+
+#### Can I manage my own certificates rather than having Synapse renew certificates itself?
+
+Yes, you are welcome to manage your certificates yourself. Synapse will only
+attempt to obtain certificates from Let's Encrypt if you configure it to do
+so.The only requirement is that there is a valid TLS cert present for
+federation end points.
+
+#### Do you still recommend against using a reverse proxy on the federation port?
+
+We no longer actively recommend against using a reverse proxy. Many admins will
+find it easier to direct federation traffic to a reverse proxy and manage their
+own TLS certificates, and this is a supported configuration.
+
+See [reverse_proxy.md](reverse_proxy.md) for information on setting up a
+reverse proxy.
+
+#### Do I still need to give my TLS certificates to Synapse if I am using a reverse proxy?
+
+Practically speaking, this is no longer necessary.
+
+If you are using a reverse proxy for all of your TLS traffic, then you can set
+`no_tls: True` in the Synapse config. In that case, the only reason Synapse
+needs the certificate is to populate a legacy `tls_fingerprints` field in the
+federation API. This is ignored by Synapse 0.99.0 and later, and the only time
+pre-0.99 Synapses will check it is when attempting to fetch the server keys -
+and generally this is delegated via `matrix.org`, which will be running a modern
+version of Synapse.
+
+#### Do I need the same certificate for the client and federation port?
+
+No. There is nothing stopping you from using different certificates,
+particularly if you are using a reverse proxy. However, Synapse will use the
+same certificate on any ports where TLS is configured.

+# SAML Mapping Providers
+
+A SAML mapping provider is a Python class (loaded via a Python module) that
+works out how to map attributes of a SAML response object to Matrix-specific
+user attributes. Details such as user ID localpart, displayname, and even avatar
+URLs are all things that can be mapped from talking to a SSO service.
+
+As an example, a SSO service may return the email address
+"john.smith@example.com" for a user, whereas Synapse will need to figure out how
+to turn that into a displayname when creating a Matrix user for this individual.
+It may choose `John Smith`, or `Smith, John [Example.com]` or any number of
+variations. As each Synapse configuration may want something different, this is
+where SAML mapping providers come into play.
+
+## Enabling Providers
+
+External mapping providers are provided to Synapse in the form of an external
+Python module. Retrieve this module from [PyPi](https://pypi.org) or elsewhere,
+then tell Synapse where to look for the handler class by editing the
+`saml2_config.user_mapping_provider.module` config option.
+
+`saml2_config.user_mapping_provider.config` allows you to provide custom
+configuration options to the module. Check with the module's documentation for
+what options it provides (if any). The options listed by default are for the
+user mapping provider built in to Synapse. If using a custom module, you should
+comment these options out and use those specified by the module instead.
+
+## Building a Custom Mapping Provider
+
+A custom mapping provider must specify the following methods:
+
+* `__init__(self, parsed_config)`
+   - Arguments:
+     - `parsed_config` - A configuration object that is the return value of the
+       `parse_config` method. You should set any configuration options needed by
+       the module here.
+* `saml_response_to_user_attributes(self, saml_response, failures)`
+    - Arguments:
+      - `saml_response` - A `saml2.response.AuthnResponse` object to extract user
+                          information from.
+      - `failures` - An `int` that represents the amount of times the returned
+                     mxid localpart mapping has failed.  This should be used
+                     to create a deduplicated mxid localpart which should be
+                     returned instead. For example, if this method returns
+                     `john.doe` as the value of `mxid_localpart` in the returned
+                     dict, and that is already taken on the homeserver, this
+                     method will be called again with the same parameters but
+                     with failures=1. The method should then return a different
+                     `mxid_localpart` value, such as `john.doe1`.
+    - This method must return a dictionary, which will then be used by Synapse
+      to build a new user. The following keys are allowed:
+       * `mxid_localpart` - Required. The mxid localpart of the new user.
+       * `displayname` - The displayname of the new user. If not provided, will default to
+                         the value of `mxid_localpart`.
+* `parse_config(config)`
+    - This method should have the `@staticmethod` decoration.
+    - Arguments:
+        - `config` - A `dict` representing the parsed content of the
+          `saml2_config.user_mapping_provider.config` homeserver config option.
+           Runs on homeserver startup. Providers should extract any option values
+           they need here.
+    - Whatever is returned will be passed back to the user mapping provider module's
+      `__init__` method during construction.
+* `get_saml_attributes(config)`
+    - This method should have the `@staticmethod` decoration.
+    - Arguments:
+        - `config` - A object resulting from a call to `parse_config`.
+    - Returns a tuple of two sets. The first set equates to the saml auth
+      response attributes that are required for the module to function, whereas
+      the second set consists of those attributes which can be used if available,
+      but are not necessary.
+
+## Synapse's Default Provider
+
+Synapse has a built-in SAML mapping provider if a custom provider isn't
+specified in the config. It is located at
+[`synapse.handlers.saml_handler.DefaultSamlMappingProvider`](../synapse/handlers/saml_handler.py).

-# A cache 'factor' is a multiplier that can be applied to each of
-# Synapse's caches in order to increase or decrease the maximum

-# 'name' gives the database engine to use: either 'sqlite3' (for SQLite) or
-# 'psycopg2' (for PostgreSQL).
-#
-# 'args' gives options which are passed through to the database engine,
-# except for options starting 'cp_', which are used to configure the Twisted
-# connection pool. For a reference to valid arguments, see:
-#   * for sqlite: https://docs.python.org/3/library/sqlite3.html#sqlite3.connect

-# Handling spam in Synapse
-
-Synapse has support to customize spam checking behavior. It can plug into a
-variety of events and affect how they are presented to users on your homeserver.
-
-The spam checking behavior is implemented as a Python class, which must be
-able to be imported by the running Synapse.
-
-## Python spam checker class
-
-The Python class is instantiated with two objects:
-
-* Any configuration (see below).
-* An instance of `synapse.spam_checker_api.SpamCheckerApi`.
-
-It then implements methods which return a boolean to alter behavior in Synapse.
-
-There's a generic method for checking every event (`check_event_for_spam`), as
-well as some specific methods:
-
-* `user_may_invite`
-* `user_may_create_room`
-* `user_may_create_room_alias`
-* `user_may_publish_room`
-
-The details of the each of these methods (as well as their inputs and outputs)
-are documented in the `synapse.events.spamcheck.SpamChecker` class.
-
-The `SpamCheckerApi` class provides a way for the custom spam checker class to
-call back into the homeserver internals. It currently implements the following
-methods:
-
-* `get_state_events_in_room`
-
-### Example
-
-```python
-class ExampleSpamChecker:
-    def __init__(self, config, api):
-        self.config = config
-        self.api = api
-
-    def check_event_for_spam(self, foo):
-        return False  # allow all events
-
-    def user_may_invite(self, inviter_userid, invitee_userid, room_id):
-        return True  # allow all invites
-
-    def user_may_create_room(self, userid):
-        return True  # allow all room creations
-
-    def user_may_create_room_alias(self, userid, room_alias):
-        return True  # allow all room aliases
-
-    def user_may_publish_room(self, userid, room_id):
-        return True  # allow publishing of all rooms
-
-    def check_username_for_spam(self, user_profile):
-        return False  # allow all usernames
-```
-
-## Configuration
-
-Modify the `spam_checker` section of your `homeserver.yaml` in the following
-manner:
-
-Create a list entry with the keys `module` and `config`.
-
-* `module` should point to the fully qualified Python class that implements your
-  custom logic, e.g. `my_module.ExampleSpamChecker`.
-
-* `config` is a dictionary that gets passed to the spam checker class.
-
-### Example
-
-This section might look like:
-
-```yaml
-spam_checker:
-  - module: my_module.ExampleSpamChecker
-    config:
-      # Enable or disable a specific option in ExampleSpamChecker.
-      my_custom_option: true
-```
-
-More spam checkers can be added in tandem by appending more items to the list. An
-action is blocked when at least one of the configured spam checkers flags it.
-
-## Examples
-
-The [Mjolnir](https://github.com/matrix-org/mjolnir) project is a full fledged
-example using the Synapse spam checking API, including a bot for dynamic
-configuration.

-# SSO Mapping Providers
-
-A mapping provider is a Python class (loaded via a Python module) that
-works out how to map attributes of a SSO response to Matrix-specific
-user attributes. Details such as user ID localpart, displayname, and even avatar
-URLs are all things that can be mapped from talking to a SSO service.
-
-As an example, a SSO service may return the email address
-"john.smith@example.com" for a user, whereas Synapse will need to figure out how
-to turn that into a displayname when creating a Matrix user for this individual.
-It may choose `John Smith`, or `Smith, John [Example.com]` or any number of
-variations. As each Synapse configuration may want something different, this is
-where SAML mapping providers come into play.
-
-SSO mapping providers are currently supported for OpenID and SAML SSO
-configurations. Please see the details below for how to implement your own.
-
-External mapping providers are provided to Synapse in the form of an external
-Python module. You can retrieve this module from [PyPi](https://pypi.org) or elsewhere,
-but it must be importable via Synapse (e.g. it must be in the same virtualenv
-as Synapse). The Synapse config is then modified to point to the mapping provider
-(and optionally provide additional configuration for it).
-
-## OpenID Mapping Providers
-
-The OpenID mapping provider can be customized by editing the
-`oidc_config.user_mapping_provider.module` config option.
-
-`oidc_config.user_mapping_provider.config` allows you to provide custom
-configuration options to the module. Check with the module's documentation for
-what options it provides (if any). The options listed by default are for the
-user mapping provider built in to Synapse. If using a custom module, you should
-comment these options out and use those specified by the module instead.
-
-### Building a Custom OpenID Mapping Provider
-
-A custom mapping provider must specify the following methods:
-
-* `__init__(self, parsed_config)`
-   - Arguments:
-     - `parsed_config` - A configuration object that is the return value of the
-       `parse_config` method. You should set any configuration options needed by
-       the module here.
-* `parse_config(config)`
-    - This method should have the `@staticmethod` decoration.
-    - Arguments:
-        - `config` - A `dict` representing the parsed content of the
-          `oidc_config.user_mapping_provider.config` homeserver config option.
-           Runs on homeserver startup. Providers should extract and validate
-           any option values they need here.
-    - Whatever is returned will be passed back to the user mapping provider module's
-      `__init__` method during construction.
-* `get_remote_user_id(self, userinfo)`
-    - Arguments:
-      - `userinfo` - A `authlib.oidc.core.claims.UserInfo` object to extract user
-                     information from.
-    - This method must return a string, which is the unique identifier for the
-      user. Commonly the ``sub`` claim of the response.
-* `map_user_attributes(self, userinfo, token)`
-    - This method should be async.
-    - Arguments:
-      - `userinfo` - A `authlib.oidc.core.claims.UserInfo` object to extract user
-                     information from.
-      - `token` - A dictionary which includes information necessary to make
-                  further requests to the OpenID provider.
-    - Returns a dictionary with two keys:
-      - localpart: A required string, used to generate the Matrix ID.
-      - displayname: An optional string, the display name for the user.
-
-### Default OpenID Mapping Provider
-
-Synapse has a built-in OpenID mapping provider if a custom provider isn't
-specified in the config. It is located at
-[`synapse.handlers.oidc_handler.JinjaOidcMappingProvider`](../synapse/handlers/oidc_handler.py).
-
-## SAML Mapping Providers
-
-The SAML mapping provider can be customized by editing the
-`saml2_config.user_mapping_provider.module` config option.
-
-`saml2_config.user_mapping_provider.config` allows you to provide custom
-configuration options to the module. Check with the module's documentation for
-what options it provides (if any). The options listed by default are for the
-user mapping provider built in to Synapse. If using a custom module, you should
-comment these options out and use those specified by the module instead.
-
-### Building a Custom SAML Mapping Provider
-
-A custom mapping provider must specify the following methods:
-
-* `__init__(self, parsed_config)`
-   - Arguments:
-     - `parsed_config` - A configuration object that is the return value of the
-       `parse_config` method. You should set any configuration options needed by
-       the module here.
-* `parse_config(config)`
-    - This method should have the `@staticmethod` decoration.
-    - Arguments:
-        - `config` - A `dict` representing the parsed content of the
-          `saml_config.user_mapping_provider.config` homeserver config option.
-           Runs on homeserver startup. Providers should extract and validate
-           any option values they need here.
-    - Whatever is returned will be passed back to the user mapping provider module's
-      `__init__` method during construction.
-* `get_saml_attributes(config)`
-    - This method should have the `@staticmethod` decoration.
-    - Arguments:
-        - `config` - A object resulting from a call to `parse_config`.
-    - Returns a tuple of two sets. The first set equates to the SAML auth
-      response attributes that are required for the module to function, whereas
-      the second set consists of those attributes which can be used if available,
-      but are not necessary.
-* `get_remote_user_id(self, saml_response, client_redirect_url)`
-    - Arguments:
-      - `saml_response` - A `saml2.response.AuthnResponse` object to extract user
-                          information from.
-      - `client_redirect_url` - A string, the URL that the client will be
-                                redirected to.
-    - This method must return a string, which is the unique identifier for the
-      user. Commonly the ``uid`` claim of the response.
-* `saml_response_to_user_attributes(self, saml_response, failures, client_redirect_url)`
-    - Arguments:
-      - `saml_response` - A `saml2.response.AuthnResponse` object to extract user
-                          information from.
-      - `failures` - An `int` that represents the amount of times the returned
-                     mxid localpart mapping has failed.  This should be used
-                     to create a deduplicated mxid localpart which should be
-                     returned instead. For example, if this method returns
-                     `john.doe` as the value of `mxid_localpart` in the returned
-                     dict, and that is already taken on the homeserver, this
-                     method will be called again with the same parameters but
-                     with failures=1. The method should then return a different
-                     `mxid_localpart` value, such as `john.doe1`.
-      - `client_redirect_url` - A string, the URL that the client will be
-                                redirected to.
-    - This method must return a dictionary, which will then be used by Synapse
-      to build a new user. The following keys are allowed:
-       * `mxid_localpart` - Required. The mxid localpart of the new user.
-       * `displayname` - The displayname of the new user. If not provided, will default to
-                         the value of `mxid_localpart`.
-
-### Default SAML Mapping Provider
-
-Synapse has a built-in SAML mapping provider if a custom provider isn't
-specified in the config. It is located at
-[`synapse.handlers.saml_handler.DefaultSamlMappingProvider`](../synapse/handlers/saml_handler.py).

-# Setting up Synapse with Workers and Systemd
-
-This is a setup for managing synapse with systemd, including support for
-managing workers. It provides a `matrix-synapse` service for the master, as
-well as a `matrix-synapse-worker@` service template for any workers you
-require. Additionally, to group the required services, it sets up a
-`matrix-synapse.target`.
-
-See the folder [system](system) for the systemd unit files.
-
-The folder [workers](workers) contains an example configuration for the
-`federation_reader` worker.
-
-## Synapse configuration files
-
-See [workers.md](../workers.md) for information on how to set up the
-configuration files and reverse-proxy correctly. You can find an example worker
-config in the [workers](workers) folder.
-
-Systemd manages daemonization itself, so ensure that none of the configuration
-files set either `daemonize` or `worker_daemonize`.
-
-The config files of all workers are expected to be located in
-`/etc/matrix-synapse/workers`. If you want to use a different location, edit
-the provided `*.service` files accordingly.
-
-There is no need for a separate configuration file for the master process.
-
-## Set up
-
-1. Adjust synapse configuration files as above.
-1. Copy the `*.service` and `*.target` files in [system](system) to
-`/etc/systemd/system`.
-1. Run `systemctl deamon-reload` to tell systemd to load the new unit files.
-1. Run `systemctl enable matrix-synapse.service`. This will configure the
-synapse master process to be started as part of the `matrix-synapse.target`
-target.
-1. For each worker process to be enabled, run `systemctl enable
-matrix-synapse-worker@<worker_name>.service`. For each `<worker_name>`, there
-should be a corresponding configuration file
-`/etc/matrix-synapse/workers/<worker_name>.yaml`.
-1. Start all the synapse processes with `systemctl start matrix-synapse.target`.
-1. Tell systemd to start synapse on boot with `systemctl enable matrix-synapse.target`/
-
-## Usage
-
-Once the services are correctly set up, you can use the following commands
-to manage your synapse installation:
-
-```sh
-# Restart Synapse master and all workers
-systemctl restart matrix-synapse.target
-
-# Stop Synapse and all workers
-systemctl stop matrix-synapse.target
-
-# Restart the master alone
-systemctl start matrix-synapse.service
-
-# Restart a specific worker (eg. federation_reader); the master is
-# unaffected by this.
-systemctl restart matrix-synapse-worker@federation_reader.service
-
-# Add a new worker (assuming all configs are set up already)
-systemctl enable matrix-synapse-worker@federation_writer.service
-systemctl restart matrix-synapse.target
-```

-### **Experimental** support for replication over redis
-
-As of Synapse v1.13.0, it is possible to configure Synapse to send replication
-via a [Redis pub/sub channel](https://redis.io/topics/pubsub). This is an
-alternative to direct TCP connections to the master: rather than all the
-workers connecting to the master, all the workers and the master connect to
-Redis, which relays replication commands between processes. This can give a
-significant cpu saving on the master and will be a prerequisite for upcoming
-performance improvements.
-
-Note that this support is currently experimental; you may experience lost
-messages and similar problems! It is strongly recommended that admins setting
-up workers for the first time use direct TCP replication as above.
-
-To configure Synapse to use Redis:
-
-1. Install Redis following the normal procedure for your distribution - for
-   example, on Debian, `apt install redis-server`. (It is safe to use an
-   existing Redis deployment if you have one: we use a pub/sub stream named
-   according to the `server_name` of your synapse server.)
-2. Check Redis is running and accessible: you should be able to `echo PING | nc -q1
-   localhost 6379` and get a response of `+PONG`.
-3. Install the python prerequisites. If you installed synapse into a
-   virtualenv, this can be done with:
-   ```sh
-   pip install matrix-synapse[redis]
-   ```
-   The debian packages from matrix.org already include the required
-   dependencies.
-4. Add config to the shared configuration (`homeserver.yaml`):
-    ```yaml
-    redis:
-      enabled: true
-    ```
-    Optional parameters which can go alongside `enabled` are `host`, `port`,
-    `password`. Normally none of these are required.
-5. Restart master and all workers.
-
-Once redis replication is in use, `worker_replication_port` is redundant and
-can be removed from the worker configuration files. Similarly, the
-configuration for the `listener` for the TCP replication port can be removed
-from the main configuration file. Note that the HTTP replication port is
-still required.
-
-### Using synctl
-
-If you want to use `synctl` to manage your synapse processes, you will need to
-create an an additional configuration file for the master synapse process. That
-configuration should look like this:
-
-```yaml
-worker_app: synapse.app.homeserver
-```
-
-Additionally, each worker app must be configured with the name of a "pid file",
-to which it will write its process ID when it starts. For example, for a
-synchrotron, you might write:
