Unreleased
==========
Changes in synapse v0.30.0 (2018-05-24)
==========================================
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``.
'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!

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.

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.

Changes in synapse v0.27.3-rc2 (2018-04-09)
==========================================

Changes in synapse v0.27.3-rc1 (2018-04-09)
=======================================
Notable changes include API support for joinability of groups. Also new metrics
and phone home stats. Phone home stats include better visibility of system usage
so we can tweak synpase to work better for all users rather than our own experience
with matrix.org. Also, recording 'r30' stat which is the measure we use to track
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"
Features:
* Add joinability for groups (PR #3045)
* Implement group join API (PR #3046)
* Add counter metrics for calculating state delta (PR #3033)
* R30 stats (PR #3041)
* Measure time it takes to calculate state group ID (PR #3043)
* Add basic performance statistics to phone home (PR #3044)
* Add response size metrics (PR #3071)
* phone home cache size configurations (PR #3063)
Changes:
* Add a blurb explaining the main synapse worker (PR #2886) Thanks to @turt2live!
* Replace old style error catching with 'as' keyword (PR #3000) Thanks to @NotAFile!
* Use .iter* to avoid copies in StateHandler (PR #3006)

Changes in synapse v0.26.1 (2018-03-15)
=======================================
Bug fixes:
* Fix bug where an invalid event caused server to stop functioning correctly,
due to parsing and serializing bugs in ujson library (PR #3008)
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.
Features:
* Add ability for ASes to override message send time (PR #2754)
* Add support for custom storage providers for media repository (PR #2867, #2777, #2783, #2789, #2791, #2804, #2812, #2814, #2857, #2868, #2767)
* Add purge API features, see `docs/admin_api/purge_history_api.rst <docs/admin_api/purge_history_api.rst>`_ for full details (PR #2858, #2867, #2882, #2946, #2962, #2943)
* Add support for whitelisting 3PIDs that users can register. (PR #2813)
* Add ``/room/{id}/event/{id}`` API (PR #2766)
* Add an admin API to get all the media in a room (PR #2818) Thanks to @turt2live!
* Add ``federation_domain_whitelist`` option (PR #2820, #2821)
Changes:
* Continue to factor out processing from main process and into worker processes. See updated `docs/workers.rst <docs/workers.rst>`_ (PR #2892 - #2904, #2913, #2920 - #2926, #2947, #2847, #2854, #2872, #2873, #2874, #2928, #2929, #2934, #2856, #2976 - #2984, #2987 - #2989, #2991 - #2993, #2995, #2784)
* Ensure state cache is used when persisting events (PR #2864, #2871, #2802, #2835, #2836, #2841, #2842, #2849)
* Change the default config to bind on both IPv4 and IPv6 on all platforms (PR #2435) Thanks to @silkeh!
* No longer require a specific version of saml2 (PR #2695) Thanks to @okurz!
* Remove ``verbosity``/``log_file`` from generated config (PR #2755)
* Add and improve metrics and logging (PR #2770, #2778, #2785, #2786, #2787, #2793, #2794, #2795, #2809, #2810, #2833, #2834, #2844, #2965, #2927, #2975, #2790, #2796, #2838)
* When using synctl with workers, don't start the main synapse automatically (PR #2774)
* Minor performance improvements (PR #2773, #2792)
* Use a connection pool for non-federation outbound connections (PR #2817)
* Make it possible to run unit tests against postgres (PR #2829)
* Update pynacl dependency to 1.2.1 or higher (PR #2888) Thanks to @bachp!
* Remove ability for AS users to call /events and /sync (PR #2948)
* Use bcrypt.checkpw (PR #2949) Thanks to @krombel!
Bug fixes:
* Fix broken ``ldap_config`` config option (PR #2683) Thanks to @seckrv!
* Fix error message when user is not allowed to unban (PR #2761) Thanks to @turt2live!

Running the Integration Tests
=============================
Synapse is accompanied by `SyTest <https://github.com/matrix-org/sytest>`_,
a Matrix homeserver integration testing suite, which uses HTTP requests to
access the API as a Matrix client would. It is able to run Synapse directly from
the source tree, so installation of the server is not required.
Testing with SyTest is recommended for verifying that changes related to the
Client-Server API are functioning correctly. See the `installation instructions

Upgrading to $NEXT_VERSION
====================
This release expands the anonymous usage stats sent if the opt-in
``report_stats`` configuration is set to ``true``. We now capture RSS memory
and cpu use at a very coarse level. This requires administrators to install
the optional ``psutil`` python module.
We would appreciate it if you could assist by ensuring this module is available
and ``report_stats`` is enabled. This will let us see if performance changes to
synapse are having an impact to the general community.

# 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.

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=''>>

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

If the event is invalid, then this method throws a FederationError.
(The error will then be logged and sent back to the sender (which
probably won't do anything with it), and other events in the
transaction will be processed as normal).
It is likely that we'll then receive other events which refer to
this rejected_event in their prev_events, etc. When that happens,
we'll attempt to fetch the rejected event again, which will presumably
fail, so those second-generation events will also get rejected.
Eventually, we get to the point where there are more than 10 events
between any new events and the original rejected event. Since we
only try to backfill 10 events deep on received pdu, we then accept the
new event, possibly introducing a discontinuity in the DAG, with new
forward extremities, so normal service is approximately returned,
until we try to backfill across the discontinuity.
Args:
origin (str): server which sent the pdu
pdu (FrozenEvent): received pdu
Returns (Deferred): completes with None
Raises: FederationError if the signatures / hash do not match
Raises: FederationError if the signatures / hash do not match, or
if the event was unacceptable for any other reason (eg, too large,
too many prev_events, couldn't find the prev_events)
