+Changes in <unreleased>
+=======================
+
+This release adds an index to the events table. This means that on first
+startup there will be an inceased amount of IO until the index is created, and
+an increase in disk usage.
+
+
+Changes in synapse v0.30.0 (2018-05-24)
+==========================================
+
+'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 policies (see ``docs/consent_tracking.md``),
+however the intention is that they may also find a use for features such
+as "Message of the day".
+
+This feature is specific to Synapse, but uses standard Matrix communication mechanisms,
+so should work with any Matrix client. For more details see ``docs/server_notices.md``
+
+Further Server Notices/Consent Tracking Support:
+
+* Allow overriding the server_notices user's avatar (PR #3273)
+* Use the localpart in the consent uri (PR #3272)
+* Support for putting %(consent_uri)s in messages (PR #3271)
+* Block attempts to send server notices to remote users (PR #3270)
+* Docs on consent bits (PR #3268)
+
+
+
+Changes in synapse v0.30.0-rc1 (2018-05-23)
+==========================================
+
+Server Notices/Consent Tracking Support:
+
+* ConsentResource to gather policy consent from users (PR #3213)
+* Move RoomCreationHandler out of synapse.handlers.Handlers (PR #3225)
+* Infrastructure for a server notices room (PR #3232)
+* Send users a server notice about consent (PR #3236)
+* Reject attempts to send event before privacy consent is given (PR #3257)
+* Add a 'has_consented' template var to consent forms (PR #3262)
+* Fix dependency on jinja2 (PR #3263)
+
+Features:
+
+* Cohort analytics (PR #3163, #3241, #3251)
+* Add lxml to docker image for web previews (PR #3239) Thanks to @ptman!
+* Add in flight request metrics (PR #3252)

+Changes in synapse v0.29.1 (2018-05-17)
+==========================================
+Changes:
+
+* Update docker documentation (PR #3222)
+
+Changes in synapse v0.29.0 (2018-05-16)
+===========================================
+Not changes since v0.29.0-rc1
+
+Changes in synapse v0.29.0-rc1 (2018-05-14)
+===========================================
+
+Notable changes, a docker file for running Synapse (Thanks to @kaiyou!) and a
+closed spec bug in the Client Server API. Additionally further prep for Python 3
+migration.
+
+Potentially breaking change:
+
+* Make Client-Server API return 401 for invalid token (PR #3161).
+
+  This changes the Client-server spec to return a 401 error code instead of 403
+  when the access token is unrecognised. This is the behaviour required by the
+  specification, but some clients may be relying on the old, incorrect
+  behaviour.
+
+  Thanks to @NotAFile for fixing this.
+
+Features:
+
+* Add a Dockerfile for synapse (PR #2846) Thanks to @kaiyou!

+* Make 'unexpected logging context' into warnings (PR #3007)
+* Set Server header in SynapseRequest (PR #3208)
+* remove duplicates from groups tables (PR #3129)
+* Improve exception handling for background processes (PR #3138)
+* Add missing consumeErrors to improve exception handling (PR #3139)
+* reraise exceptions more carefully (PR #3142)
+* Remove redundant call to preserve_fn (PR #3143)

+
+Changes in synapse v0.28.1 (2018-05-01)
+=======================================
+
+SECURITY UPDATE
+
+* Clamp the allowed values of event depth received over federation to be
+  [0, 2^63 - 1].  This mitigates an attack where malicious events
+  injected with depth = 2^63 - 1 render rooms unusable.  Depth is used to
+  determine the cosmetic ordering of events within a room, and so the ordering
+  of events in such a room will default to using stream_ordering rather than depth
+  (topological_ordering).
+
+  This is a temporary solution to mitigate abuse in the wild, whilst a long term solution
+  is being implemented to improve how the depth parameter is used.
+
+  Full details at
+  https://docs.google.com/document/d/1I3fi2S-XnpO45qrpCsowZv8P8dHcNZ4fsBsbOW7KABI
+
+* Pin Twisted to <18.4 until we stop using the private _OpenSSLECCurve API.
+
+

+overal growth of the Matrix ecosystem. It is defined as:-
+
+Counts the number of native 30 day retained users, defined as:-
+         * Users who have created their accounts more than 30 days
+         * Where last seen at most 30 days ago
+         * Where account creation and last_seen are > 30 days"

+
+
+Changes in synapse v0.27.0-rc1 (2018-03-14)
+===========================================
+
+The common case for running Synapse is not to run separate workers, but for those that do, be aware that synctl no longer starts the main synapse when using ``-a`` option with workers. A new worker file should be added with ``worker_app: synapse.app.homeserver``.
+
+This release also begins the process of renaming a number of the metrics
+reported to prometheus. See `docs/metrics-howto.rst <docs/metrics-howto.rst#block-and-response-metrics-renamed-for-0-27-0>`_.
+Note that the v0.28.0 release will remove the deprecated metric names.

+However, for federation to work on hosts with IPv6 DNS servers you **must**

+yet as it will break most older distributions (see https://github.com/matrix-org/synapse/pull/1909)
+so if you are using operating system dependencies you'll have to install your
+own Twisted 17.1 package via pip or backports etc.

+If you're running in a virtualenv then pip should have installed the newest

+Running out of File Handles
+~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+If synapse runs out of filehandles, it typically fails badly - live-locking
+at 100% CPU, and/or failing to accept new TCP connections (blocking the
+connecting client).  Matrix currently can legitimately use a lot of file handles,
+thanks to busy rooms like #matrix:matrix.org containing hundreds of participating
+servers.  The first time a server talks in a room it will try to connect
+simultaneously to all participating servers, which could exhaust the available
+file descriptors between DNS queries & HTTPS sockets, especially if DNS is slow
+to respond.  (We need to improve the routing algorithm used to be better than
+full mesh, but as of June 2017 this hasn't happened yet).
+
+If you hit this failure mode, we recommend increasing the maximum number of
+open file handles to be at least 4096 (assuming a default of 1024 or 256).
+This is typically done by editing ``/etc/security/limits.conf``
+
+Separately, Synapse may leak file handles if inbound HTTP requests get stuck
+during processing - e.g. blocked behind a lock or talking to a remote server etc.
+This is best diagnosed by matching up the 'Received request' and 'Processed request'
+log lines and looking for any 'Processed request' lines which take more than
+a few seconds to execute.  Please let us know at #matrix-dev:matrix.org if
+you see this failure mode so we can help debug it, however.

+# 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.

+This directory contains some sample monitoring config for using the
+'Prometheus' monitoring server against synapse.
+
+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.

+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')
+<Deferred at 0x7ff253fc6998 current result: <FrozenEvent event_id='$1416420717069yeQaw:matrix.org', type='m.room.create', state_key=''>>

+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.
+
+    Alternatively, the ``Deferred`` can resolve to a ``(str, func)`` tuple, in
+    which case the second field is a callback which will be called with the
+    result from the ``/login`` call (including ``access_token``, ``device_id``,
+    etc.)
+
+``someprovider.check_password``\(*user_id*, *password*)
+
+    This method provides a simpler interface than ``get_supported_login_types``
+    and ``check_auth`` for password auth providers that just want to provide a
+    mechanism for validating ``m.login.password`` logins.
+
+    Iif implemented, it will be called to check logins with an
+    ``m.login.password`` login type. It is passed a qualified
+    ``@localpart:domain`` user id, and the password provided by the user.
+
+    The method should return a Twisted ``Deferred`` object, which resolves to
+    ``True`` if authentication is successful, and ``False`` if not.
+
+``someprovider.on_logged_out``\(*user_id*, *device_id*, *access_token*)
+
+    This method, if implemented, is called when a user logs out. It is passed
+    the qualified user ID, the ID of the deactivated device (if any: access
+    tokens are occasionally created without an associated device ID), and the
+    (now deactivated) access token.
+
+    It may return a Twisted ``Deferred`` object; the logout request will wait
+    for the deferred to complete but the result is ignored.

+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. They also cannot leave it.
+
+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'})
+```

+TCP Replication
+===============
+
+Motivation
+----------
+
+Previously the workers used an HTTP long poll mechanism to get updates from the
+master, which had the problem of causing a lot of duplicate work on the server.
+This TCP protocol replaces those APIs with the aim of increased efficiency.
+
+
+
+Overview
+--------
+
+The protocol is based on fire and forget, line based commands. An example flow
+would be (where '>' indicates master to worker and '<' worker to master flows)::
+
+    > SERVER example.com
+    < REPLICATE events 53
+    > RDATA events 54 ["$foo1:bar.com", ...]
+    > RDATA events 55 ["$foo4:bar.com", ...]
+
+The example shows the server accepting a new connection and sending its identity
+with the ``SERVER`` command, followed by the client asking to subscribe to the
+``events`` stream from the token ``53``. The server then periodically sends ``RDATA``
+commands which have the format ``RDATA <stream_name> <token> <row>``, where the
+format of ``<row>`` is defined by the individual streams.
+
+Error reporting happens by either the client or server sending an `ERROR`
+command, and usually the connection will be closed.
+
+
+Since the protocol is a simple line based, its possible to manually connect to
+the server using a tool like netcat. A few things should be noted when manually
+using the protocol:
+
+* When subscribing to a stream using ``REPLICATE``, the special token ``NOW`` can
+  be used to get all future updates. The special stream name ``ALL`` can be used
+  with ``NOW`` to subscribe to all available streams.
+* The federation stream is only available if federation sending has been
+  disabled on the main process.
+* The server will only time connections out that have sent a ``PING`` command.
+  If a ping is sent then the connection will be closed if no further commands
+  are receieved within 15s. Both the client and server protocol implementations
+  will send an initial PING on connection and ensure at least one command every
+  5s is sent (not necessarily ``PING``).
+* ``RDATA`` commands *usually* include a numeric token, however if the stream
+  has multiple rows to replicate per token the server will send multiple
+  ``RDATA`` commands, with all but the last having a token of ``batch``. See
+  the documentation on ``commands.RdataCommand`` for further details.
+
+
+Architecture
+------------
+
+The basic structure of the protocol is line based, where the initial word of
+each line specifies the command. The rest of the line is parsed based on the
+command. For example, the `RDATA` command is defined as::
+
+    RDATA <stream_name> <token> <row_json>
+
+(Note that `<row_json>` may contains spaces, but cannot contain newlines.)
+
+Blank lines are ignored.
+
+
+Keep alives
+~~~~~~~~~~~
+
+Both sides are expected to send at least one command every 5s or so, and
+should send a ``PING`` command if necessary. If either side do not receive a
+command within e.g. 15s then the connection should be closed.
+
+Because the server may be connected to manually using e.g. netcat, the timeouts
+aren't enabled until an initial ``PING`` command is seen. Both the client and
+server implementations below send a ``PING`` command immediately on connection to
+ensure the timeouts are enabled.
+
+This ensures that both sides can quickly realize if the tcp connection has gone
+and handle the situation appropriately.
+
+
+Start up
+~~~~~~~~
+
+When a new connection is made, the server:
+
+* Sends a ``SERVER`` command, which includes the identity of the server, allowing
+  the client to detect if its connected to the expected server
+* Sends a ``PING`` command as above, to enable the client to time out connections
+  promptly.
+
+The client:
+
+* Sends a ``NAME`` command, allowing the server to associate a human friendly
+  name with the connection. This is optional.
+* Sends a ``PING`` as above
+* For each stream the client wishes to subscribe to it sends a ``REPLICATE``
+  with the stream_name and token it wants to subscribe from.
+* On receipt of a ``SERVER`` command, checks that the server name matches the
+  expected server name.
+
+
+Error handling
+~~~~~~~~~~~~~~
+
+If either side detects an error it can send an ``ERROR`` command and close the
+connection.
+
+If the client side loses the connection to the server it should reconnect,
+following the steps above.
+
+
+Congestion
+~~~~~~~~~~
+
+If the server sends messages faster than the client can consume them the server
+will first buffer a (fairly large) number of commands and then disconnect the
+client. This ensures that we don't queue up an unbounded number of commands in
+memory and gives us a potential oppurtunity to squawk loudly. When/if the client
+recovers it can reconnect to the server and ask for missed messages.
+
+
+Reliability
+~~~~~~~~~~~
+
+In general the replication stream should be considered an unreliable transport
+since e.g. commands are not resent if the connection disappears.
+
+The exception to that are the replication streams, i.e. RDATA commands, since
+these include tokens which can be used to restart the stream on connection
+errors.
+
+The client should keep track of the token in the last RDATA command received
+for each stream so that on reconneciton it can start streaming from the correct
+place. Note: not all RDATA have valid tokens due to batching. See
+``RdataCommand`` for more details.
+
+
+Example
+~~~~~~~
+
+An example iteraction is shown below. Each line is prefixed with '>' or '<' to
+indicate which side is sending, these are *not* included on the wire::
+
+    * connection established *
+    > SERVER localhost:8823
+    > PING 1490197665618
+    < NAME synapse.app.appservice
+    < PING 1490197665618
+    < REPLICATE events 1
+    < REPLICATE backfill 1
+    < REPLICATE caches 1
+    > POSITION events 1
+    > POSITION backfill 1
+    > POSITION caches 1
+    > RDATA caches 2 ["get_user_by_id",["@01register-user:localhost:8823"],1490197670513]
+    > RDATA events 14 ["$149019767112vOHxz:localhost:8823",
+        "!AFDCvgApUmpdfVjIXm:localhost:8823","m.room.guest_access","",null]
+    < PING 1490197675618
+    > ERROR server stopping
+    * connection closed by server *
+
+The ``POSITION`` command sent by the server is used to set the clients position
+without needing to send data with the ``RDATA`` command.
+
+
+An example of a batched set of ``RDATA`` is::
+
+    > RDATA caches batch ["get_user_by_id",["@test:localhost:8823"],1490197670513]
+    > RDATA caches batch ["get_user_by_id",["@test2:localhost:8823"],1490197670513]
+    > RDATA caches batch ["get_user_by_id",["@test3:localhost:8823"],1490197670513]
+    > RDATA caches 54 ["get_user_by_id",["@test4:localhost:8823"],1490197670513]
+
+In this case the client shouldn't advance their caches token until it sees the
+the last ``RDATA``.

 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
 horizontally independently.
 
+All of the below is highly experimental and subject to change as Synapse evolves,
+but documenting it here to help folks needing highly scalable Synapses similar
+to the one running matrix.org!
+
 All processes continue to share the same database instance, and as such, workers
 only work with postgres based synapse deployments (sharing a single sqlite
 across multiple processes is a recipe for disaster, plus you should be using
 postgres anyway if you care about scalability).
 
 The workers communicate with the master synapse process via a synapse-specific
-HTTP protocol called 'replication' - analogous to MySQL or Postgres style
+TCP protocol called 'replication' - analogous to MySQL or Postgres style
 database replication; feeding a stream of relevant data to the workers so they
 can be kept in sync with the main synapse process and database state.
 
-To enable workers, you need to add a replication listener to the master synapse, e.g.::
+Configuration
+-------------
+
+To make effective use of the workers, you will need to configure an HTTP
+reverse-proxy such as nginx or haproxy, which will direct incoming requests to
+the correct worker, or to the main synapse instance. Note that this includes
+requests made to the federation port. The caveats regarding running a
+reverse-proxy on the federation port still apply (see
+https://github.com/matrix-org/synapse/blob/master/README.rst#reverse-proxying-the-federation-port).
+
+To enable workers, you need to add two replication listeners to the master
+synapse, e.g.::
 
     listeners:
+      # The TCP replication port
       - port: 9092
+        bind_address: '127.0.0.1'
+        type: replication
+      # The HTTP replication port
+      - port: 9093
         bind_address: '127.0.0.1'
         type: http

-        x_forwarded: false
         resources:
-          - names: [replication]
+         - names: [replication]
-            compress: false

+
- * synapse.app.client_reader - handles client API endpoints like /publicRooms
+    worker_app: synapse.app.homeserver
+    daemonize: true
 
 Each worker configuration file inherits the configuration of the main homeserver
 configuration file.  You can then override configuration specific to that worker,
 e.g. the HTTP listener that it provides (if any); logging configuration; etc.
 You should minimise the number of overrides though to maintain a usable config.

+Available worker applications
+-----------------------------
+
+``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/state_ids/
+    ^/_matrix/federation/v1/backfill/
+    ^/_matrix/federation/v1/get_missing_events/
+    ^/_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$
+
+``synapse.app.user_dir``
+~~~~~~~~~~~~~~~~~~~~~~~~
+
+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
+instance to be persisted and handled.
