<h2 id="choosing-your-server-name"><a class="header" href="#choosing-your-server-name">Choosing your server name</a></h2>
|
|||
|
<p>It is important to choose the name for your server before you install Synapse,
|
|||
|
because it cannot be changed later.</p>
|
|||
|
<p>The server name determines the "domain" part of user-ids for users on your
|
|||
|
server: these will all be of the format <code>@user:my.domain.name</code>. It also
|
|||
|
determines how other matrix servers will reach yours for federation.</p>
|
|||
|
<p>For a test configuration, set this to the hostname of your server. For a more
|
|||
|
production-ready setup, you will probably want to specify your domain
|
|||
|
(<code>example.com</code>) rather than a matrix-specific hostname here (in the same way
|
|||
|
that your email address is probably <code>user@example.com</code> rather than
|
|||
|
<code>user@email.example.com</code>) - but doing so may require more advanced setup: see
|
|||
|
<a href="setup/../federate.html">Setting up Federation</a>.</p>

|
<h3 id="installing-from-source"><a class="header" href="#installing-from-source">Installing from source</a></h3>
|
|||
|
<p>(Prebuilt packages are available for some platforms - see <a href="setup/installation.html#prebuilt-packages">Prebuilt packages</a>.)</p>
|
|||
|
<p>When installing from source please make sure that the <a href="setup/installation.html#platform-specific-prerequisites">Platform-specific prerequisites</a> are already installed.</p>
|
|||
|
<p>System requirements:</p>
|
|||
|
<ul>
|
|||
|
<li>POSIX-compliant system (tested on Linux & OS X)</li>
|
|||
|
<li>Python 3.5.2 or later, up to Python 3.9.</li>
|
|||
|
<li>At least 1GB of free RAM if you want to join large public rooms like #matrix:matrix.org</li>
|
|||
|
</ul>
|
|||
|
<p>To install the Synapse homeserver run:</p>
|
|||
|
<pre><code class="language-sh">mkdir -p ~/synapse
|
|||
|
virtualenv -p python3 ~/synapse/env
|
|||
|
source ~/synapse/env/bin/activate
|
|||
|
pip install --upgrade pip
|
|||
|
pip install --upgrade setuptools
|
|||
|
pip install matrix-synapse
|
|||
|
</code></pre>
|
|||
|
<p>This will download Synapse from <a href="https://pypi.org/project/matrix-synapse">PyPI</a>
|
|||
|
and install it, along with the python libraries it uses, into a virtual environment
|
|||
|
under <code>~/synapse/env</code>. Feel free to pick a different directory if you
|
|||
|
prefer.</p>
|
|||
|
<p>This Synapse installation can then be later upgraded by using pip again with the
|
|||
|
update flag:</p>
|
|||
|
<pre><code class="language-sh">source ~/synapse/env/bin/activate
|
|||
|
pip install -U matrix-synapse
|
|||
|
</code></pre>
|
|||
|
<p>Before you can start Synapse, you will need to generate a configuration
|
|||
|
file. To do this, run (in your virtualenv, as before):</p>
|
|||
|
<pre><code class="language-sh">cd ~/synapse
|
|||
|
python -m synapse.app.homeserver \
|
|||
|
--server-name my.domain.name \
|
|||
|
--config-path homeserver.yaml \
|
|||
|
--generate-config \
|
|||
|
--report-stats=[yes|no]
|
|||
|
</code></pre>
|
|||
|
<p>... substituting an appropriate value for <code>--server-name</code>.</p>
|
|||
|
<p>This command will generate you a config file that you can then customise, but it will
|
|||
|
also generate a set of keys for you. These keys will allow your homeserver to
|
|||
|
identify itself to other homeserver, so don't lose or delete them. It would be
|
|||
|
wise to back them up somewhere safe. (If, for whatever reason, you do need to
|
|||
|
change your homeserver's keys, you may find that other homeserver have the
|
|||
|
old key cached. If you update the signing key, you should change the name of the
|
|||
|
key in the <code><server name>.signing.key</code> file (the second word) to something
|
|||
|
different. See the <a href="https://matrix.org/docs/spec/server_server/latest.html#retrieving-server-keys">spec</a> for more information on key management).</p>
|
|||
|
<p>To actually run your new homeserver, pick a working directory for Synapse to
|
|||
|
run (e.g. <code>~/synapse</code>), and:</p>
|
|||
|
<pre><code class="language-sh">cd ~/synapse
|
|||
|
source env/bin/activate
|
|||
|
synctl start
|
|||
|
</code></pre>
|
|||
|
<h4 id="platform-specific-prerequisites"><a class="header" href="#platform-specific-prerequisites">Platform-specific prerequisites</a></h4>
|
|||
|
<p>Synapse is written in Python but some of the libraries it uses are written in
|
|||
|
C. So before we can install Synapse itself we need a working C compiler and the
|
|||
|
header files for Python C extensions.</p>

<p>A port of Synapse is available under <code>net/synapse</code>. The filesystem

underlying the homeserver directory (defaults to <code>/var/synapse</code>) has to be

<h3 id="using-postgresql"><a class="header" href="#using-postgresql">Using PostgreSQL</a></h3>
|
|||
|
<p>By default Synapse uses an <a href="https://sqlite.org/">SQLite</a> database and in doing so trades
|
|||
|
performance for convenience. Almost all installations should opt to use <a href="https://www.postgresql.org">PostgreSQL</a>
|
|||
|
instead. Advantages include:</p>
|
|||
|
<ul>
|
|||
|
<li>significant performance improvements due to the superior threading and
|
|||
|
caching model, smarter query optimiser</li>
|
|||
|
<li>allowing the DB to be run on separate hardware</li>
|
|||
|
</ul>
|
|||
|
<p>For information on how to install and use PostgreSQL in Synapse, please see
|
|||
|
<a href="setup/../postgres.html">Using Postgres</a></p>
|
|||
|
<p>SQLite is only acceptable for testing purposes. SQLite should not be used in
|
|||
|
a production server. Synapse will perform poorly when using
|
|||
|
SQLite, especially when participating in large rooms.</p>
|
|||
|
<h3 id="tls-certificates"><a class="header" href="#tls-certificates">TLS certificates</a></h3>
|
|||
|
<p>The default configuration exposes a single HTTP port on the local
|
|||
|
interface: <code>http://localhost:8008</code>. It is suitable for local testing,
|
|||
|
but for any practical use, you will need Synapse's APIs to be served
|
|||
|
over HTTPS.</p>
|
|||
|
<p>The recommended way to do so is to set up a reverse proxy on port
|
|||
|
<code>8448</code>. You can find documentation on doing so in
|
|||
|
<a href="setup/../reverse_proxy.html">the reverse proxy documentation</a>.</p>
|
|||
|
<p>Alternatively, you can configure Synapse to expose an HTTPS port. To do
|
|||
|
so, you will need to edit <code>homeserver.yaml</code>, as follows:</p>
|
|||
|
<ul>
|
|||
|
<li>First, under the <code>listeners</code> section, uncomment the configuration for the
|
|||
|
TLS-enabled listener. (Remove the hash sign (<code>#</code>) at the start of
|
|||
|
each line). The relevant lines are like this:</li>
|
|||
|
</ul>
|
|||
|
<pre><code class="language-yaml"> - port: 8448
|
|||
|
type: http
|
|||
|
tls: true
|
|||
|
resources:
|
|||
|
- names: [client, federation]
|
|||
|
</code></pre>
|
|||
|
<ul>
|
|||
|
<li>
|
|||
|
<p>You will also need to uncomment the <code>tls_certificate_path</code> and
|
|||
|
<code>tls_private_key_path</code> lines under the <code>TLS</code> section. You will need to manage
|
|||
|
provisioning of these certificates yourself.</p>
|
|||
|
<p>If you are using your own certificate, be sure to use a <code>.pem</code> file that
|
|||
|
includes the full certificate chain including any intermediate certificates
|
|||
|
(for instance, if using certbot, use <code>fullchain.pem</code> as your certificate, not
|
|||
|
<code>cert.pem</code>).</p>
|
|||
|
</li>
|
|||
|
</ul>
|
|||
|

<h3 id="client-well-known-uri"><a class="header" href="#client-well-known-uri">Client Well-Known URI</a></h3>
|
|||
|
<p>Setting up the client Well-Known URI is optional but if you set it up, it will
|
|||
|
allow users to enter their full username (e.g. <code>@user:<server_name></code>) into clients
|
|||
|
which support well-known lookup to automatically configure the homeserver and
|
|||
|
identity server URLs. This is useful so that users don't have to memorize or think
|
|||
|
about the actual homeserver URL you are using.</p>
|
|||
|
<p>The URL <code>https://<server_name>/.well-known/matrix/client</code> should return JSON in
|
|||
|
the following format.</p>
|
|||
|
<pre><code class="language-json">{
|
|||
|
"m.homeserver": {
|
|||
|
"base_url": "https://<matrix.example.com>"
|
|||
|
}
|
|||
|
}
|
|||
|
</code></pre>
|
|||
|
<p>It can optionally contain identity server information as well.</p>
|
|||
|
<pre><code class="language-json">{
|
|||
|
"m.homeserver": {
|
|||
|
"base_url": "https://<matrix.example.com>"
|
|||
|
},
|
|||
|
"m.identity_server": {
|
|||
|
"base_url": "https://<identity.example.com>"
|
|||
|
}
|
|||
|
}
|
|||
|
</code></pre>
|
|||
|
<p>To work in browser based clients, the file must be served with the appropriate
|
|||
|
Cross-Origin Resource Sharing (CORS) headers. A recommended value would be
|
|||
|
<code>Access-Control-Allow-Origin: *</code> which would allow all browser based clients to
|
|||
|
view it.</p>
|
|||
|
<p>In nginx this would be something like:</p>
|
|||
|
<pre><code class="language-nginx">location /.well-known/matrix/client {
|
|||
|
return 200 '{"m.homeserver": {"base_url": "https://<matrix.example.com>"}}';
|
|||
|
default_type application/json;
|
|||
|
add_header Access-Control-Allow-Origin *;
|
|||
|
}
|
|||
|
</code></pre>
|
|||
|
<p>You should also ensure the <code>public_baseurl</code> option in <code>homeserver.yaml</code> is set
|
|||
|
correctly. <code>public_baseurl</code> should be set to the URL that clients will use to
|
|||
|
connect to your server. This is the same URL you put for the <code>m.homeserver</code>
|
|||
|
<code>base_url</code> above.</p>
|
|||
|
<pre><code class="language-yaml">public_baseurl: "https://<matrix.example.com>"
|
|||
|
</code></pre>
|
|||
|
<h3 id="email"><a class="header" href="#email">Email</a></h3>
|
|||
|
<p>It is desirable for Synapse to have the capability to send email. This allows
|
|||
|
Synapse to send password reset emails, send verifications when an email address
|
|||
|
is added to a user's account, and send email notifications to users when they
|
|||
|
receive new messages.</p>
|
|||
|
<p>To configure an SMTP server for Synapse, modify the configuration section
|
|||
|
headed <code>email</code>, and be sure to have at least the <code>smtp_host</code>, <code>smtp_port</code>
|
|||
|
and <code>notif_from</code> fields filled out. You may also need to set <code>smtp_user</code>,
|
|||
|
<code>smtp_pass</code>, and <code>require_transport_security</code>.</p>
|
|||
|
<p>If email is not configured, password reset, registration and notifications via
|
|||
|
email will be disabled.</p>
|
|||
|
<h3 id="registering-a-user"><a class="header" href="#registering-a-user">Registering a user</a></h3>
|
|||
|
<p>The easiest way to create a new user is to do so from a client like <a href="https://element.io/">Element</a>.</p>
|
|||
|
<p>Alternatively, you can do so from the command line. This can be done as follows:</p>
|
|||
|
<ol>
|
|||
|
<li>If synapse was installed via pip, activate the virtualenv as follows (if Synapse was
|
|||
|
installed via a prebuilt package, <code>register_new_matrix_user</code> should already be
|
|||
|
on the search path):
|
|||
|
<pre><code class="language-sh">cd ~/synapse
|
|||
|
source env/bin/activate
|
|||
|
synctl start # if not already running
|
|||
|
</code></pre>
|
|||
|
</li>
|
|||
|
<li>Run the following command:
|
|||
|
<pre><code class="language-sh">register_new_matrix_user -c homeserver.yaml http://localhost:8008
|
|||
|
</code></pre>
|
|||
|
</li>
|
|||
|
</ol>
|
|||
|
<p>This will prompt you to add details for the new user, and will then connect to
|
|||
|
the running Synapse to create the new user. For example:</p>
|
|||
|
<pre><code>New user localpart: erikj
|
|||
|
Password:
|
|||
|
Confirm password:
|
|||
|
Make admin [no]:
|
|||
|
Success!
|
|||
|
</code></pre>
|
|||
|
<p>This process uses a setting <code>registration_shared_secret</code> in
|
|||
|
<code>homeserver.yaml</code>, which is shared between Synapse itself and the
|
|||
|
<code>register_new_matrix_user</code> script. It doesn't matter what it is (a random
|
|||
|
value is generated by <code>--generate-config</code>), but it should be kept secret, as
|
|||
|
anyone with knowledge of it can register users, including admin accounts,
|
|||
|
on your server even if <code>enable_registration</code> is <code>false</code>.</p>
|
|||
|
<h3 id="setting-up-a-turn-server"><a class="header" href="#setting-up-a-turn-server">Setting up a TURN server</a></h3>
|
|||
|
<p>For reliable VoIP calls to be routed via this homeserver, you MUST configure
|
|||
|
a TURN server. See <a href="setup/../turn-howto.html">TURN setup</a> for details.</p>
|
|||
|
<h3 id="url-previews"><a class="header" href="#url-previews">URL previews</a></h3>
|
|||
|
<p>Synapse includes support for previewing URLs, which is disabled by default. To
|
|||
|
turn it on you must enable the <code>url_preview_enabled: True</code> config parameter
|
|||
|
and explicitly specify the IP ranges that Synapse is not allowed to spider for
|
|||
|
previewing in the <code>url_preview_ip_range_blacklist</code> configuration parameter.
|
|||
|
This is critical from a security perspective to stop arbitrary Matrix users
|
|||
|
spidering 'internal' URLs on your network. At the very least we recommend that
|
|||
|
your loopback and RFC1918 IP addresses are blacklisted.</p>
|
|||
|
<p>This also requires the optional <code>lxml</code> python dependency to be installed. This
|
|||
|
in turn requires the <code>libxml2</code> library to be available - on Debian/Ubuntu this
|

<p><code>pip</code> seems to leak <em>lots</em> of memory during installation. For instance, a Linux

host with 512MB of RAM may run out of memory whilst installing Twisted. If this

|
<li>
|

<p>Assuming your PostgreSQL database user is called <code>postgres</code>, first authenticate as the database user with:</p>
|

|
<pre><code>su - postgres
|

|
# Or, if your system uses sudo to get administrative rights
|
|||
|
sudo -u postgres bash
|

<p>Then, create a postgres user and a database with:</p>
|

|
<pre><code># this will prompt for a password for the new user
|
|||
|
createuser --pwprompt synapse_user

|
createdb --encoding=UTF8 --locale=C --template=template0 --owner=synapse_user synapse
|

|
<p>The above will create a user called <code>synapse_user</code>, and a database called
|
|||
|
<code>synapse</code>.</p>
|
|||
|
<p>Note that the PostgreSQL database <em>must</em> have the correct encoding set
|

|
(as shown above), otherwise it will not be able to store UTF8 strings.</p>
|

<p>You may need to enable password authentication so <code>synapse_user</code> can

<p>When you are ready to start using PostgreSQL, edit the <code>database</code>
|

|
section in your config file to match the following lines:</p>
|
|||
|
<pre><code class="language-yaml">database:
|

<p>All key, values in <code>args</code> are passed to the <code>psycopg2.connect(..)</code>
|

|
function, except keys beginning with <code>cp_</code>, which are consumed by the

|
<p>You should consider tuning the <code>args.keepalives_*</code> options if there is any danger of
|
|||
|
the connection between your homeserver and database dropping, otherwise Synapse
|
|||
|
may block for an extended period while it waits for a response from the
|

|
database server. Example values might be:</p>
|

<h3 id="overview"><a class="header" href="#overview">Overview</a></h3>
|
|||
|
<p>The script <code>synapse_port_db</code> allows porting an existing synapse server
|
|||
|
backed by SQLite to using PostgreSQL. This is done in as a two phase
|
|||
|
process:</p>
|
|||
|
<ol>
|
|||
|
<li>Copy the existing SQLite database to a separate location and run
|
|||
|
the port script against that offline database.</li>
|
|||
|
<li>Shut down the server. Rerun the port script to port any data that
|
|||
|
has come in since taking the first snapshot. Restart server against
|
|||
|
the PostgreSQL database.</li>
|
|||
|
</ol>
|
|||
|
<p>The port script is designed to be run repeatedly against newer snapshots
|
|||
|
of the SQLite database file. This makes it safe to repeat step 1 if
|
|||
|
there was a delay between taking the previous snapshot and being ready
|
|||
|
to do step 2.</p>
|
|||
|
<p>It is safe to at any time kill the port script and restart it.</p>
|
|||
|
<p>Note that the database may take up significantly more (25% - 100% more)
|
|||
|
space on disk after porting to Postgres.</p>
|
|||
|
<h3 id="using-the-port-script"><a class="header" href="#using-the-port-script">Using the port script</a></h3>
|
|||
|
<p>Firstly, shut down the currently running synapse server and copy its
|
|||
|
database file (typically <code>homeserver.db</code>) to another location. Once the
|
|||
|
copy is complete, restart synapse. For instance:</p>
|
|||
|
<pre><code>./synctl stop
|
|||
|
cp homeserver.db homeserver.db.snapshot
|
|||
|
./synctl start
|
|||
|
</code></pre>
|
|||
|
<p>Copy the old config file into a new config file:</p>
|
|||
|
<pre><code>cp homeserver.yaml homeserver-postgres.yaml
|
|||
|
</code></pre>
|
|||
|
<p>Edit the database section as described in the section <em>Synapse config</em>
|
|||
|
above and with the SQLite snapshot located at <code>homeserver.db.snapshot</code>
|
|||
|
simply run:</p>
|
|||
|
<pre><code>synapse_port_db --sqlite-database homeserver.db.snapshot \
|
|||
|
--postgres-config homeserver-postgres.yaml
|
|||
|
</code></pre>
|
|||
|
<p>The flag <code>--curses</code> displays a coloured curses progress UI.</p>
|
|||
|
<p>If the script took a long time to complete, or time has otherwise passed
|
|||
|
since the original snapshot was taken, repeat the previous steps with a
|
|||
|
newer snapshot.</p>
|
|||
|
<p>To complete the conversion shut down the synapse server and run the port
|
|||
|
script one last time, e.g. if the SQLite database is at <code>homeserver.db</code>
|
|||
|
run:</p>
|
|||
|
<pre><code>synapse_port_db --sqlite-database homeserver.db \
|
|||
|
--postgres-config homeserver-postgres.yaml
|
|||
|
</code></pre>
|
|||
|
<p>Once that has completed, change the synapse config to point at the
|
|||
|
PostgreSQL database configuration file <code>homeserver-postgres.yaml</code>:</p>
|
|||
|
<pre><code>./synctl stop
|
|||
|
mv homeserver.yaml homeserver-old-sqlite.yaml
|
|||
|
mv homeserver-postgres.yaml homeserver.yaml
|
|||
|
./synctl start
|
|||
|
</code></pre>
|
|||
|
<p>Synapse should now be running against PostgreSQL.</p>

<h3 id="alternative-auth-methods"><a class="header" href="#alternative-auth-methods">Alternative auth methods</a></h3>
|
|||
|
<p>If you get an error along the lines of <code>FATAL: Ident authentication failed for user "synapse_user"</code>, you may need to use an authentication method other than
|
|||
|
<code>ident</code>:</p>
|
|||
|
<ul>
|
|||
|
<li>
|
|||
|
<p>If the <code>synapse_user</code> user has a password, add the password to the <code>database:</code>
|
|||
|
section of <code>homeserver.yaml</code>. Then add the following to <code>pg_hba.conf</code>:</p>
|
|||
|
<pre><code>host synapse synapse_user ::1/128 md5 # or `scram-sha-256` instead of `md5` if you use that
|
|||
|
</code></pre>
|
|||
|
</li>
|
|||
|
<li>
|
|||
|
<p>If the <code>synapse_user</code> user does not have a password, then a password doesn't
|
|||
|
have to be added to <code>homeserver.yaml</code>. But the following does need to be added
|
|||
|
to <code>pg_hba.conf</code>:</p>
|
|||
|
<pre><code>host synapse synapse_user ::1/128 trust
|
|||
|
</code></pre>
|
|||
|
</li>
|
|||
|
</ul>
|
|||
|
<p>Note that line order matters in <code>pg_hba.conf</code>, so make sure that if you do add a
|
|||
|
new line, it is inserted before:</p>
|
|||
|
<pre><code>host all all ::1/128 ident
|
|||
|
</code></pre>

<h3 id="fixing-incorrect-collate-or-ctype"><a class="header" href="#fixing-incorrect-collate-or-ctype">Fixing incorrect <code>COLLATE</code> or <code>CTYPE</code></a></h3>
|
|||
|
<p>Synapse will refuse to set up a new database if it has the wrong values of
|
|||
|
<code>COLLATE</code> and <code>CTYPE</code> set, and will log warnings on existing databases. Using
|
|||
|
different locales can cause issues if the locale library is updated from
|
|||
|
underneath the database, or if a different version of the locale is used on any
|
|||
|
replicas.</p>
|
|||
|
<p>The safest way to fix the issue is to dump the database and recreate it with
|
|||
|
the correct locale parameter (as shown above). It is also possible to change the
|
|||
|
parameters on a live database and run a <code>REINDEX</code> on the entire database,
|
|||
|
however extreme care must be taken to avoid database corruption.</p>
|
|||
|
<p>Note that the above may fail with an error about duplicate rows if corruption
|
|||
|
has already occurred, and such duplicate rows will need to be manually removed.</p>

<h3 id="fixing-inconsistent-sequences-error"><a class="header" href="#fixing-inconsistent-sequences-error">Fixing inconsistent sequences error</a></h3>
|
|||
|
<p>Synapse uses Postgres sequences to generate IDs for various tables. A sequence
|
|||
|
and associated table can get out of sync if, for example, Synapse has been
|
|||
|
downgraded and then upgraded again.</p>
|
|||
|
<p>To fix the issue shut down Synapse (including any and all workers) and run the
|
|||
|
SQL command included in the error message. Once done Synapse should start
|
|||
|
successfully.</p>

|
|||
|
<p>It is recommended to put a reverse proxy such as
|
|||
|
<a href="https://nginx.org/en/docs/http/ngx_http_proxy_module.html">nginx</a>,
|
|||
|
<a href="https://httpd.apache.org/docs/current/mod/mod_proxy_http.html">Apache</a>,
|
|||
|
<a href="https://caddyserver.com/docs/quick-starts/reverse-proxy">Caddy</a>,
|
|||
|
<a href="https://www.haproxy.org/">HAProxy</a> or
|
|||
|
<a href="https://man.openbsd.org/relayd.8">relayd</a> in front of Synapse. One advantage
|
|||
|
of doing so is that it means that you can expose the default https port
|
|||
|
(443) to Matrix clients without needing to run Synapse with root
|
|||
|
privileges.</p>
|
|||
|
<p>You should configure your reverse proxy to forward requests to <code>/_matrix</code> or
|
|||
|
<code>/_synapse/client</code> to Synapse, and have it set the <code>X-Forwarded-For</code> and
|
|||
|
<code>X-Forwarded-Proto</code> request headers.</p>
|
|||
|
<p>You should remember that Matrix clients and other Matrix servers do not
|
|||
|
necessarily need to connect to your server via the same server name or
|
|||
|
port. Indeed, clients will use port 443 by default, whereas servers default to
|
|||
|
port 8448. Where these are different, we refer to the 'client port' and the
|
|||
|
'federation port'. See <a href="https://matrix.org/docs/spec/server_server/latest#resolving-server-names">the Matrix
|
|||
|
specification</a>
|
|||
|
for more details of the algorithm used for federation connections, and
|
|||
|
<a href="delegate.html">Delegation</a> for instructions on setting up delegation.</p>
|
|||
|
<p><strong>NOTE</strong>: Your reverse proxy must not <code>canonicalise</code> or <code>normalise</code>
|
|||
|
the requested URI in any way (for example, by decoding <code>%xx</code> escapes).
|
|||
|
Beware that Apache <em>will</em> canonicalise URIs unless you specify
|
|||
|
<code>nocanon</code>.</p>
|
|||
|
<p>Let's assume that we expect clients to connect to our server at
|
|||
|
<code>https://matrix.example.com</code>, and other servers to connect at
|
|||
|
<code>https://example.com:8448</code>. The following sections detail the configuration of
|
|||
|
the reverse proxy and the homeserver.</p>
|
|||
|
<h2 id="homeserver-configuration"><a class="header" href="#homeserver-configuration">Homeserver Configuration</a></h2>
|
|||
|
<p>The HTTP configuration will need to be updated for Synapse to correctly record
|
|||
|
client IP addresses and generate redirect URLs while behind a reverse proxy. </p>
|
|||
|
<p>In <code>homeserver.yaml</code> set <code>x_forwarded: true</code> in the port 8008 section and
|
|||
|
consider setting <code>bind_addresses: ['127.0.0.1']</code> so that the server only
|
|||
|
listens to traffic on localhost. (Do not change <code>bind_addresses</code> to <code>127.0.0.1</code>
|
|||
|
when using a containerized Synapse, as that will prevent it from responding
|
|||
|
to proxied traffic.)</p>

<p>Synapse exposes a health check endpoint for use by reverse proxies.

Each configured HTTP listener has a <code>/health</code> endpoint which always returns

|
<p>Endpoints for administering your Synapse instance are placed under

|
<code>/_synapse/admin</code>. These require authentication through an access token of an
|
|||
|
admin user. However as access to these endpoints grants the caller a lot of power,
|
|||
|
we do not recommend exposing them to the public internet without good reason.</p>

|
|||
|
<p>You can use Synapse with a forward or outbound proxy. An example of when
|
|||
|
this is necessary is in corporate environments behind a DMZ (demilitarized zone).
|
|||
|
Synapse supports routing outbound HTTP(S) requests via a proxy. Only HTTP(S)
|
|||
|
proxy is supported, not SOCKS proxy or anything else.</p>
|
|||
|
<h2 id="configure"><a class="header" href="#configure">Configure</a></h2>
|
|||
|
<p>The <code>http_proxy</code>, <code>https_proxy</code>, <code>no_proxy</code> environment variables are used to
|
|||
|
specify proxy settings. The environment variable is not case sensitive.</p>
|
|||
|
<ul>
|
|||
|
<li><code>http_proxy</code>: Proxy server to use for HTTP requests.</li>
|
|||
|
<li><code>https_proxy</code>: Proxy server to use for HTTPS requests.</li>
|
|||
|
<li><code>no_proxy</code>: Comma-separated list of hosts, IP addresses, or IP ranges in CIDR
|
|||
|
format which should not use the proxy. Synapse will directly connect to these hosts.</li>
|
|||
|
</ul>
|
|||
|
<p>The <code>http_proxy</code> and <code>https_proxy</code> environment variables have the form: <code>[scheme://][<username>:<password>@]<host>[:<port>]</code></p>
|
|||
|
<ul>
|
|||
|
<li>
|
|||
|
<p>Supported schemes are <code>http://</code> and <code>https://</code>. The default scheme is <code>http://</code>
|
|||
|
for compatibility reasons; it is recommended to set a scheme. If scheme is set
|
|||
|
to <code>https://</code> the connection uses TLS between Synapse and the proxy.</p>
|
|||
|
<p><strong>NOTE</strong>: Synapse validates the certificates. If the certificate is not
|
|||
|
valid, then the connection is dropped.</p>
|

<p><strong>Examples</strong></p>

|
|||
|
</ul>
|
|||
|
<p><strong>NOTE</strong>:
|
|||
|
Synapse does not apply the IP blacklist to connections through the proxy (since
|
|||
|
the DNS resolution is done by the proxy). It is expected that the proxy or firewall
|
|||
|
will apply blacklisting of IP addresses.</p>

<h2 id="troubleshooting-1"><a class="header" href="#troubleshooting-1">Troubleshooting</a></h2>
|

|
<p>If a proxy server is used with TLS (HTTPS) and no connections are established,
|

|
it is most likely due to the proxy's certificates. To test this, the validation

in Synapse can be deactivated.</p>
|
|||
|
<p><strong>NOTE</strong>: This has an impact on security and is for testing purposes only!</p>
|

|
<p>This document explains how to enable VoIP relaying on your Home Server with
|
|||
|
TURN.</p>
|
|||
|
<p>The synapse Matrix Home Server supports integration with TURN server via the
|
|||
|
<a href="https://tools.ietf.org/html/draft-uberti-behave-turn-rest-00">TURN server REST API</a>. This
|
|||
|
allows the Home Server to generate credentials that are valid for use on the
|
|||
|
TURN server through the use of a secret shared between the Home Server and the
|
|||
|
TURN server.</p>
|
|||
|
<p>The following sections describe how to install <a href="https://github.com/coturn/coturn">coturn</a> (which implements the TURN REST API) and integrate it with synapse.</p>
|
|||
|
<h2 id="requirements"><a class="header" href="#requirements">Requirements</a></h2>
|
|||
|
<p>For TURN relaying with <code>coturn</code> to work, it must be hosted on a server/endpoint with a public IP.</p>
|
|||
|
<p>Hosting TURN behind a NAT (even with appropriate port forwarding) is known to cause issues
|
|||
|
and to often not work.</p>
|
|||
|

|
|||
|
<h3 id="initial-installation"><a class="header" href="#initial-installation">Initial installation</a></h3>
|
|||
|
<p>The TURN daemon <code>coturn</code> is available from a variety of sources such as native package managers, or installation from source.</p>
|
|||
|
<h4 id="debian-installation"><a class="header" href="#debian-installation">Debian installation</a></h4>
|
|||
|
<p>Just install the debian package:</p>
|
|||
|
<pre><code class="language-sh">apt install coturn
|
|||
|
</code></pre>
|
|||
|
<p>This will install and start a systemd service called <code>coturn</code>.</p>
|
|||
|
<h4 id="source-installation"><a class="header" href="#source-installation">Source installation</a></h4>
|
|||
|
<ol>
|
|||
|
<li>
|
|||
|
<p>Download the <a href="https://github.com/coturn/coturn/releases/latest">latest release</a> from github. Unpack it and <code>cd</code> into the directory.</p>
|
|||
|
</li>
|
|||
|
<li>
|
|||
|
<p>Configure it:</p>
|
|||
|
<pre><code>./configure
|
|||
|
</code></pre>
|
|||
|
<p>You may need to install <code>libevent2</code>: if so, you should do so in
|
|||
|
the way recommended by your operating system. You can ignore
|
|||
|
warnings about lack of database support: a database is unnecessary
|
|||
|
for this purpose.</p>
|
|||
|
</li>
|
|||
|
<li>
|
|||
|
<p>Build and install it:</p>
|
|||
|
<pre><code>make
|
|||
|
make install
|
|||
|
</code></pre>
|
|||
|
</li>
|
|||
|
</ol>
|
|||
|
<h3 id="configuration"><a class="header" href="#configuration">Configuration</a></h3>
|
|||
|
<ol>
|
|||
|
<li>
|
|||
|
<p>Create or edit the config file in <code>/etc/turnserver.conf</code>. The relevant
|
|||
|
lines, with example values, are:</p>
|
|||
|
<pre><code>use-auth-secret
|
|||
|
static-auth-secret=[your secret key here]
|
|||
|
realm=turn.myserver.org
|
|||
|
</code></pre>
|
|||
|
<p>See <code>turnserver.conf</code> for explanations of the options. One way to generate
|
|||
|
the <code>static-auth-secret</code> is with <code>pwgen</code>:</p>
|
|||
|
<pre><code>pwgen -s 64 1
|
|||
|
</code></pre>
|
|||
|
<p>A <code>realm</code> must be specified, but its value is somewhat arbitrary. (It is
|
|||
|
sent to clients as part of the authentication flow.) It is conventional to
|
|||
|
set it to be your server name.</p>
|
|||
|
</li>
|
|||
|
<li>
|
|||
|
<p>You will most likely want to configure coturn to write logs somewhere. The
|
|||
|
easiest way is normally to send them to the syslog:</p>
|
|||
|
<pre><code>syslog
|
|||
|
</code></pre>
|
|||
|
<p>(in which case, the logs will be available via <code>journalctl -u coturn</code> on a
|
|||
|
systemd system). Alternatively, coturn can be configured to write to a
|
|||
|
logfile - check the example config file supplied with coturn.</p>
|
|||
|
</li>
|
|||
|
<li>
|
|||
|
<p>Consider your security settings. TURN lets users request a relay which will
|
|||
|
connect to arbitrary IP addresses and ports. The following configuration is
|
|||
|
suggested as a minimum starting point:</p>
|
|||
|
<pre><code># VoIP traffic is all UDP. There is no reason to let users connect to arbitrary TCP endpoints via the relay.
|
|||
|
no-tcp-relay
|
|||
|
|
|||
|
# don't let the relay ever try to connect to private IP address ranges within your network (if any)
|
|||
|
# given the turn server is likely behind your firewall, remember to include any privileged public IPs too.
|
|||
|
denied-peer-ip=10.0.0.0-10.255.255.255
|
|||
|
denied-peer-ip=192.168.0.0-192.168.255.255
|
|||
|
denied-peer-ip=172.16.0.0-172.31.255.255
|
|||
|
|
|||
|
# special case the turn server itself so that client->TURN->TURN->client flows work
|
|||
|
allowed-peer-ip=10.0.0.1
|
|||
|
|
|||
|
# consider whether you want to limit the quota of relayed streams per user (or total) to avoid risk of DoS.
|
|||
|
user-quota=12 # 4 streams per video call, so 12 streams = 3 simultaneous relayed calls per user.
|
|||
|
total-quota=1200
|
|||
|
</code></pre>
|
|||
|
</li>
|
|||
|
<li>
|
|||
|
<p>Also consider supporting TLS/DTLS. To do this, add the following settings
|
|||
|
to <code>turnserver.conf</code>:</p>
|
|||
|
<pre><code># TLS certificates, including intermediate certs.
|
|||
|
# For Let's Encrypt certificates, use `fullchain.pem` here.
|
|||
|
cert=/path/to/fullchain.pem
|
|||
|
|
|||
|
# TLS private key file
|
|||
|
pkey=/path/to/privkey.pem
|
|||
|
</code></pre>
|
|||
|
<p>In this case, replace the <code>turn:</code> schemes in the <code>turn_uri</code> settings below
|
|||
|
with <code>turns:</code>.</p>
|
|||
|
<p>We recommend that you only try to set up TLS/DTLS once you have set up a
|
|||
|
basic installation and got it working.</p>
|
|||
|
</li>
|
|||
|
<li>
|
|||
|
<p>Ensure your firewall allows traffic into the TURN server on the ports
|
|||
|
you've configured it to listen on (By default: 3478 and 5349 for TURN
|
|||
|
traffic (remember to allow both TCP and UDP traffic), and ports 49152-65535
|
|||
|
for the UDP relay.)</p>
|
|||
|
</li>
|
|||
|
<li>
|
|||
|
<p>We do not recommend running a TURN server behind NAT, and are not aware of
|
|||
|
anyone doing so successfully.</p>
|
|||
|
<p>If you want to try it anyway, you will at least need to tell coturn its
|
|||
|
external IP address:</p>
|
|||
|
<pre><code>external-ip=192.88.99.1
|
|||
|
</code></pre>
|
|||
|
<p>... and your NAT gateway must forward all of the relayed ports directly
|
|||
|
(eg, port 56789 on the external IP must be always be forwarded to port
|
|||
|
56789 on the internal IP).</p>
|
|||
|
<p>If you get this working, let us know!</p>
|
|||
|
</li>
|
|||
|
<li>
|
|||
|
<p>(Re)start the turn server:</p>
|
|||
|
<ul>
|
|||
|
<li>
|
|||
|
<p>If you used the Debian package (or have set up a systemd unit yourself):</p>
|

<pre><code class="language-sh">systemctl restart coturn
|
|||

</code></pre>
|

<h2 id="troubleshooting-2"><a class="header" href="#troubleshooting-2">Troubleshooting</a></h2>
|
|||
|
<p>The normal symptoms of a misconfigured TURN server are that calls between
|
|||
|
devices on different networks ring, but get stuck at "call
|
|||
|
connecting". Unfortunately, troubleshooting this can be tricky.</p>
|
|||
|
<p>Here are a few things to try:</p>
|
|||
|
<ul>
|
|||
|
<li>
|
|||
|
<p>Check that your TURN server is not behind NAT. As above, we're not aware of
|
|||
|
anyone who has successfully set this up.</p>
|
|||
|
</li>
|
|||
|
<li>
|
|||
|
<p>Check that you have opened your firewall to allow TCP and UDP traffic to the
|
|||
|
TURN ports (normally 3478 and 5479).</p>
|
|||
|
</li>
|
|||
|
<li>
|
|||
|
<p>Check that you have opened your firewall to allow UDP traffic to the UDP
|
|||
|
relay ports (49152-65535 by default).</p>
|
|||
|
</li>
|
|||
|
<li>
|
|||
|
<p>Some WebRTC implementations (notably, that of Google Chrome) appear to get
|
|||
|
confused by TURN servers which are reachable over IPv6 (this appears to be
|
|||
|
an unexpected side-effect of its handling of multiple IP addresses as
|
|||
|
defined by
|
|||
|
<a href="https://tools.ietf.org/html/draft-ietf-rtcweb-ip-handling-12"><code>draft-ietf-rtcweb-ip-handling</code></a>).</p>
|
|||
|
<p>Try removing any AAAA records for your TURN server, so that it is only
|
|||
|
reachable over IPv4.</p>
|
|||
|
</li>
|
|||
|
<li>
|
|||
|
<p>Enable more verbose logging in coturn via the <code>verbose</code> setting:</p>
|
|||
|
<pre><code>verbose
|
|||
|
</code></pre>
|
|||
|
<p>... and then see if there are any clues in its logs.</p>
|
|||
|
</li>
|
|||
|
<li>
|
|||
|
<p>If you are using a browser-based client under Chrome, check
|
|||
|
<code>chrome://webrtc-internals/</code> for insights into the internals of the
|
|||
|
negotiation. On Firefox, check the "Connection Log" on <code>about:webrtc</code>.</p>

<p>You can test your Matrix homeserver TURN setup with https://test.voip.librepush.net/.
|

Note that this test is not fully reliable yet, so don't be discouraged if
|

the test fails.

<p>There is a WebRTC test tool at
|

https://webrtc.github.io/samples/src/content/peerconnection/trickle-ice/. To
|
|||
|
use it, you will need a username/password for your TURN server. You can
|
|||
|
either:</p>
|
|||
|
<ul>
|
|||
|
<li>
|
|||
|
<p>look for the <code>GET /_matrix/client/r0/voip/turnServer</code> request made by a
|
|||
|
matrix client to your homeserver in your browser's network inspector. In
|
|||
|
the response you should see <code>username</code> and <code>password</code>. Or:</p>
|
|||
|
</li>
|
|||
|
<li>
|
|||
|
<p>Use the following shell commands:</p>
|
|||
|
<pre><code class="language-sh">secret=staticAuthSecretHere
|
|||
|
|
|||
|
u=$((`date +%s` + 3600)):test

|
echo -e "username: $u\npassword: $p"
|
|||
|
</code></pre>
|
|||
|
<p>Or:</p>
|
|||
|
</li>
|
|||
|
<li>
|
|||
|
<p>Temporarily configure coturn to accept a static username/password. To do
|
|||
|
this, comment out <code>use-auth-secret</code> and <code>static-auth-secret</code> and add the
|
|||
|
following:</p>
|
|||
|
<pre><code>lt-cred-mech
|
|||
|
user=username:password
|
|||
|
</code></pre>
|
|||
|
<p><strong>Note</strong>: these settings will not take effect unless <code>use-auth-secret</code>
|
|||
|
and <code>static-auth-secret</code> are disabled.</p>
|
|||
|
<p>Restart coturn after changing the configuration file.</p>
|
|||
|
<p>Remember to restore the original settings to go back to testing with
|
|||
|
Matrix clients!</p>
|
|||
|
</li>
|
|||
|
</ul>
|
|||
|
<p>If the TURN server is working correctly, you should see at least one <code>relay</code>
|
|||
|
entry in the results.</p>

<div id="chapter_begin" style="break-before: page; page-break-before: always;"></div><h1 id="delegation"><a class="header" href="#delegation">Delegation</a></h1>
|
|||
|
<p>By default, other homeservers will expect to be able to reach yours via
|
|||
|
your <code>server_name</code>, on port 8448. For example, if you set your <code>server_name</code>
|
|||
|
to <code>example.com</code> (so that your user names look like <code>@user:example.com</code>),
|
|||
|
other servers will try to connect to yours at <code>https://example.com:8448/</code>.</p>
|
|||
|
<p>Delegation is a Matrix feature allowing a homeserver admin to retain a
|
|||
|
<code>server_name</code> of <code>example.com</code> so that user IDs, room aliases, etc continue
|
|||
|
to look like <code>*:example.com</code>, whilst having federation traffic routed
|
|||
|
to a different server and/or port (e.g. <code>synapse.example.com:443</code>).</p>
|
|||
|
<h2 id="well-known-delegation"><a class="header" href="#well-known-delegation">.well-known delegation</a></h2>
|
|||
|
<p>To use this method, you need to be able to alter the
|
|||
|
<code>server_name</code> 's https server to serve the <code>/.well-known/matrix/server</code>
|
|||
|
URL. Having an active server (with a valid TLS certificate) serving your
|
|||
|
<code>server_name</code> domain is out of the scope of this documentation.</p>
|
|||
|
<p>The URL <code>https://<server_name>/.well-known/matrix/server</code> should
|
|||
|
return a JSON structure containing the key <code>m.server</code> like so:</p>
|
|||
|
<pre><code class="language-json">{
|
|||
|
"m.server": "<synapse.server.name>[:<yourport>]"
|
|||
|
}
|
|||
|
</code></pre>
|
|||
|
<p>In our example, this would mean that URL <code>https://example.com/.well-known/matrix/server</code>
|
|||
|
should return:</p>
|
|||
|
<pre><code class="language-json">{
|
|||
|
"m.server": "synapse.example.com:443"
|
|||
|
}
|
|||
|
</code></pre>
|
|||
|
<p>Note, specifying a port is optional. If no port is specified, then it defaults
|
|||
|
to 8448.</p>
|
|||
|
<p>With .well-known delegation, federating servers will check for a valid TLS
|
|||
|
certificate for the delegated hostname (in our example: <code>synapse.example.com</code>).</p>
|
|||
|
<h2 id="srv-dns-record-delegation"><a class="header" href="#srv-dns-record-delegation">SRV DNS record delegation</a></h2>
|
|||
|
<p>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 <code>.well-known</code>
|
|||
|
delegation is already enough in most cases.</p>
|
|||
|
<p>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 <a href="https://matrix.org/docs/spec/server_server/latest#resolving-server-names">the Matrix
|
|||
|
specification</a>.</p>

|
<h3 id="when-do-i-need-delegation"><a class="header" href="#when-do-i-need-delegation">When do I need delegation?</a></h3>
|
|||
|
<p>If your homeserver's APIs are accessible on the default federation port (8448)
|
|||
|
and the domain your <code>server_name</code> points to, you do not need any delegation.</p>
|
|||
|
<p>For instance, if you registered <code>example.com</code> and pointed its DNS A record at a
|
|||
|
fresh server, you could install Synapse on that host, giving it a <code>server_name</code>
|
|||
|
of <code>example.com</code>, and once a reverse proxy has been set up to proxy all requests
|
|||
|
sent to the port <code>8448</code> and serve TLS certificates for <code>example.com</code>, you
|
|||
|
wouldn't need any delegation set up.</p>
|
|||
|
<p><strong>However</strong>, if your homeserver's APIs aren't accessible on port 8448 and on the
|
|||
|
domain <code>server_name</code> points to, you will need to let other servers know how to
|
|||
|
find it using delegation.</p>
|
|||
|
<h3 id="do-you-still-recommend-against-using-a-reverse-proxy-on-the-federation-port"><a class="header" href="#do-you-still-recommend-against-using-a-reverse-proxy-on-the-federation-port">Do you still recommend against using a reverse proxy on the federation port?</a></h3>
|
|||
|
<p>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.</p>
|
|||
|
<p>See <a href="reverse_proxy.html">the reverse proxy documentation</a> for information on setting up a
|
|||
|
reverse proxy.</p>
|
|||

<h3 id="do-i-still-need-to-give-my-tls-certificates-to-synapse-if-i-am-using-a-reverse-proxy"><a class="header" href="#do-i-still-need-to-give-my-tls-certificates-to-synapse-if-i-am-using-a-reverse-proxy">Do I still need to give my TLS certificates to Synapse if I am using a reverse proxy?</a></h3>
|
|||
|
<p>This is no longer necessary. If you are using a reverse proxy for all of your
|
|||
|
TLS traffic, then you can set <code>no_tls: True</code> in the Synapse config.</p>
|
|||
|
<p>In that case, the only reason Synapse needs the certificate is to populate a legacy
|
|||
|
<code>tls_fingerprints</code> 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 <code>matrix.org</code>, which
|
|||
|
is running a modern version of Synapse.</p>
|
|||
|

|
|||
|
<p>No. There is nothing stopping you from using different certificates,
|
|||
|
particularly if you are using a reverse proxy.</p>

|
<li>
|

|
<p>Check that your versions of Python and PostgreSQL are still

|
<p>If Synapse was installed from source, then:</p>
|
|||
|
<ol>
|
|||
|
<li>
|
|||
|
<p>Activate the virtualenv before upgrading. For example, if

|
|||
|
<p>This release includes a database schema update which requires re-indexing one of
|
|||
|
the larger tables in the database, <code>events</code>. This could result in increased
|
|||
|
disk I/O for several hours or days after upgrading while the migration
|
|||
|
completes. Furthermore, because we have to keep the old indexes until the new
|
|||
|
indexes are ready, it could result in a significant, temporary, increase in
|
|||
|
disk space.</p>
|
|||
|
<p>To get a rough idea of the disk space required, check the current size of one
|
|||
|
of the indexes. For example, from a <code>psql</code> shell, run the following sql:</p>
|
|||
|
<pre><code class="language-sql">SELECT pg_size_pretty(pg_relation_size('events_order_room'));
|
|||
|
</code></pre>
|
|||
|
<p>We need to rebuild <strong>four</strong> indexes, so you will need to multiply this result
|
|||
|
by four to give an estimate of the disk space required. For example, on one
|
|||
|
particular server:</p>
|
|||
|
<pre><code>synapse=# select pg_size_pretty(pg_relation_size('events_order_room'));
|
|||
|
pg_size_pretty
|
|||
|
----------------
|
|||
|
288 MB
|
|||
|
(1 row)
|
|||
|
</code></pre>
|
|||
|
<p>On this server, it would be wise to ensure that at least 1152MB are free.</p>
|
|||
|
<p>The additional disk space will be freed once the migration completes.</p>
|
|||
|
<p>SQLite databases are unaffected by this change.</p>

|

<p>When using Synapse with a reverse proxy (in particular, when using the

|
[x_forwarded]{.title-ref} option on an HTTP listener), Synapse now
|
|||
|
expects to receive an [X-Forwarded-Proto]{.title-ref} header on incoming
|
|||
|
HTTP requests. If it is not set, Synapse will log a warning on each
|
|||
|
received request.</p>
|
|||
|
<p>To avoid the warning, administrators using a reverse proxy should ensure
|
|||
|
that the reverse proxy sets [X-Forwarded-Proto]{.title-ref} header to
|
|||
|
[https]{.title-ref} or [http]{.title-ref} to indicate the protocol used
|
|||
|
by the client.</p>
|

|
<p>Synapse also requires the [Host]{.title-ref} header to be preserved.</p>
|
|||
|
<p>See the <a href="reverse_proxy.html">reverse proxy documentation</a>, where the
|
|||
|
example configurations have been updated to show how to set these

headers.</p>

<p>(Users of <a href="https://caddyserver.com/">Caddy</a> are unaffected, since we

<ul>
|
|||
|
<li>
|
|||
|
<p>If your server is configured for single sign-on via an OpenID

|
Connect or OAuth2 identity provider, you will need to add
|
|||
|
<code>[synapse public baseurl]/_synapse/client/oidc/callback</code> to the list
|
|||
|
of permitted "redirect URIs" at the identity provider.</p>
|

|
<p>See the <a href="openid.html">OpenID docs</a> for more information on setting

up OpenID Connect.</p>

</li>
|
|||
|
<li>
|
|||
|
<p>If your server is configured for single sign-on via a SAML2 identity

<code>[synapse public baseurl]/_synapse/client/saml2/authn_response</code> as a
|
|||
|
permitted "ACS location" (also known as "allowed callback URLs")
|
|||
|
at the identity provider.</p>
|

|
<p>The "Issuer" in the "AuthnRequest" to the SAML2 identity

provider is also updated to
|

<code>[synapse public baseurl]/_synapse/client/saml2/metadata.xml</code>. If
|

your SAML2 identity provider uses this property to validate or

otherwise identify Synapse, its configuration will need to be

|
updated to use the new URL. Alternatively you could create a new,

separate "EntityDescriptor" in your SAML2 identity provider with

|
|||
|
<p>This is the last release of Synapse which guarantees support with Python
|
|||
|
3.5, which passed its upstream End of Life date several months ago.</p>
|
|||
|
<p>We will attempt to maintain support through March 2021, but without
|
|||
|
guarantees.</p>
|
|||
|
<p>In the future, Synapse will follow upstream schedules for ending support
|
|||
|
of older versions of Python and PostgreSQL. Please upgrade to at least
|
|||
|
Python 3.6 and PostgreSQL 9.6 as soon as possible.</p>

<h2 id="blacklisting-ip-ranges"><a class="header" href="#blacklisting-ip-ranges">Blacklisting IP ranges</a></h2>
|
|||
|
<p>Synapse v1.25.0 includes new settings, <code>ip_range_blacklist</code> and
|
|||
|
<code>ip_range_whitelist</code>, for controlling outgoing requests from Synapse for
|
|||
|
federation, identity servers, push, and for checking key validity for
|
|||
|
third-party invite events. The previous setting,
|
|||
|
<code>federation_ip_range_blacklist</code>, is deprecated. The new
|
|||
|
<code>ip_range_blacklist</code> defaults to private IP ranges if it is not defined.</p>
|
|||
|
<p>If you have never customised <code>federation_ip_range_blacklist</code> it is
|
|||
|
recommended that you remove that setting.</p>
|
|||
|
<p>If you have customised <code>federation_ip_range_blacklist</code> you should update
|
|||
|
the setting name to <code>ip_range_blacklist</code>.</p>
|
|||
|
<p>If you have a custom push server that is reached via private IP space
|
|||
|
you may need to customise <code>ip_range_blacklist</code> or <code>ip_range_whitelist</code>.</p>

<h2 id="custom-openid-connect-mapping-provider-breaking-change"><a class="header" href="#custom-openid-connect-mapping-provider-breaking-change">Custom OpenID Connect mapping provider breaking change</a></h2>
|
|||
|
<p>This release allows the OpenID Connect mapping provider to perform
|
|||
|
normalisation of the localpart of the Matrix ID. This allows for the
|
|||
|
mapping provider to specify different algorithms, instead of the
|
|||
|
<a href="https://matrix.org/docs/spec/appendices#mapping-from-other-character-sets">default
|
|||
|
way</a>.</p>
|
|||
|
<p>If your Synapse configuration uses a custom mapping provider
|
|||
|
([oidc_config.user_mapping_provider.module]{.title-ref} is specified and
|
|||
|
not equal to
|
|||
|
[synapse.handlers.oidc_handler.JinjaOidcMappingProvider]{.title-ref})
|
|||
|
then you <em>must</em> ensure that [map_user_attributes]{.title-ref} of the
|
|||
|
mapping provider performs some normalisation of the
|
|||
|
[localpart]{.title-ref} returned. To match previous behaviour you can
|
|||
|
use the [map_username_to_mxid_localpart]{.title-ref} function provided
|
|||
|
by Synapse. An example is shown below:</p>
|
|||
|
<pre><code class="language-python">from synapse.types import map_username_to_mxid_localpart
|
|||
|
|
|||
|
class MyMappingProvider:
|
|||

|
|||
|
# ... your custom logic ...
|
|||
|
sso_user_id = ...
|
|||
|
localpart = map_username_to_mxid_localpart(sso_user_id)
|
|||
|
|
|||
|
return {"localpart": localpart}

<h2 id="removal-historical-synapse-admin-api"><a class="header" href="#removal-historical-synapse-admin-api">Removal historical Synapse Admin API</a></h2>
|
|||
|
<p>Historically, the Synapse Admin API has been accessible under:</p>
|
|||
|
<ul>
|
|||
|
<li><code>/_matrix/client/api/v1/admin</code></li>
|
|||
|
<li><code>/_matrix/client/unstable/admin</code></li>
|
|||
|
<li><code>/_matrix/client/r0/admin</code></li>
|
|||
|
<li><code>/_synapse/admin/v1</code></li>
|
|||
|
</ul>
|
|||
|
<p>The endpoints with <code>/_matrix/client/*</code> prefixes have been removed as of
|
|||
|
v1.24.0. The Admin API is now only accessible under:</p>
|
|||
|
<ul>
|
|||
|
<li><code>/_synapse/admin/v1</code></li>
|
|||
|
</ul>
|
|||
|
<p>The only exception is the [/admin/whois]{.title-ref} endpoint, which is
|
|||
|
<a href="https://matrix.org/docs/spec/client_server/r0.6.1#get-matrix-client-r0-admin-whois-userid">also available via the client-server
|
|||
|
API</a>.</p>
|
|||
|
<p>The deprecation of the old endpoints was announced with Synapse 1.20.0
|
|||
|
(released on 2020-09-22) and makes it easier for homeserver admins to
|
|||
|
lock down external access to the Admin API endpoints.</p>

<h2 id="structured-logging-configuration-breaking-changes"><a class="header" href="#structured-logging-configuration-breaking-changes">Structured logging configuration breaking changes</a></h2>
|

|
<p>This release deprecates use of the <code>structured: true</code> logging
|

|
configuration for structured logging. If your logging configuration
|
|||
|
contains <code>structured: true</code> then it should be modified based on the
|

<a href="structured_logging.html">structured logging documentation</a>.</p>
|

|
<p>The <code>structured</code> and <code>drains</code> logging options are now deprecated and

should be replaced by standard logging configuration of <code>handlers</code> and

|

|
<p>This release introduces a backwards-incompatible change to modules
|

making use of <code>ThirdPartyEventRules</code> in Synapse. If you make use of a
|
|||
|
module defined under the <code>third_party_event_rules</code> config option, please
|
|||
|
make sure it is updated to handle the below change:</p>
|
|||
|
<p>The <code>http_client</code> argument is no longer passed to modules as they are
|
|||
|
initialised. Instead, modules are expected to make use of the
|
|||
|
<code>http_client</code> property on the <code>ModuleApi</code> class. Modules are now passed
|
|||
|
a <code>module_api</code> argument during initialisation, which is an instance of
|
|||
|
<code>ModuleApi</code>. <code>ModuleApi</code> instances have a <code>http_client</code> property which
|
|||
|
acts the same as the <code>http_client</code> argument previously passed to
|

|
<code>ThirdPartyEventRules</code> modules.</p>

<p>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.</p>
|
|||
|
<p>This will <em>not</em> be a problem for Synapse installations which were:</p>
|
|||
|
<p>: - 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.</p>
|
|||
|
<p>If completeness of the room directory is a concern, installations which
|
|||
|
are affected can be repaired as follows:</p>
|
|||
|
<ol>
|
|||
|
<li>
|
|||
|
<p>Run the following sql from a [psql]{.title-ref} or

<p>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:</p>
|
|||
|
<ol>
|
|||
|
<li>
|
|||
|
<p>Stop the server</p>
|

<p>Downgrade Synapse by following the instructions for your

<p>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.</p>
|
|||
|
<p>This is only likely to be a problem in the case of a server which is
|

|
participating in many rooms.</p>
|

<ol start="0">
|

<li>
|

<p>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.</p>
|
|||
|
</li>
|
|||
|
<li>
|
|||
|
<p>As an initial check to see if you will be affected, you can try
|
|||
|
running the following query from the [psql]{.title-ref} or
|
|||
|
[sqlite3]{.title-ref} console. It is safe to run it while Synapse is
|
|||
|
still running.</p>
|
|||
|
<pre><code class="language-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=''
|

|

|
) FROM rooms WHERE rooms.room_version IS NULL
|
|||
|
) q;
|
|||
|
</code></pre>
|
|||
|
<p>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.</p>
|
|||
|
<p>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.</p>
|
|||
|
<p>If you would prefer to reduce the downtime, continue with the steps
|
|||
|
below.</p>
|
|||
|
</li>
|
|||
|
<li>
|
|||
|
<p>The easiest workaround for this issue is to manually create a new
|
|||
|
index before upgrading. On PostgreSQL, his can be done as follows:</p>
|
|||
|
<pre><code class="language-sql">CREATE INDEX CONCURRENTLY tmp_upgrade_1_12_0_index
|
|||
|
ON state_events(room_id) WHERE type = 'm.room.create';
|
|||
|
</code></pre>
|
|||
|
<p>The above query may take some time, but is also safe to run while
|
|||
|
Synapse is running.</p>
|
|||
|
<p>We assume that no SQLite users have databases large enough to be
|
|||
|
affected. If you <em>are</em> affected, you can run a similar query,
|
|||
|
omitting the <code>CONCURRENTLY</code> keyword. Note however that this
|
|||
|
operation may in itself cause Synapse to stop running for some time.
|
|||
|
Synapse admins are reminded that <a href="postgres.html">SQLite is not recommended for use
|
|||
|
outside a test environment</a>.</p>
|
|||
|
</li>
|
|||
|
<li>
|
|||
|
<p>Once the index has been created, the <code>SELECT</code> query in step 1 above
|
|||
|
should complete quickly. It is therefore safe to upgrade to Synapse
|
|||
|
1.12.0.</p>
|
|||
|
</li>
|
|||
|
<li>
|
|||
|
<p>Once Synapse 1.12.0 has successfully started and is responding to
|
|||
|
HTTP requests, the temporary index can be removed:</p>
|
|||
|
<pre><code class="language-sql">DROP INDEX tmp_upgrade_1_12_0_index;
|
|||
|
</code></pre>
|
|||

<p>In an attempt to configure Synapse in a privacy preserving way, the
|
|||
|
default behaviours of <code>allow_public_rooms_without_auth</code> and
|
|||
|
<code>allow_public_rooms_over_federation</code> have been inverted. This means that
|
|||
|
by default, only authenticated users querying the Client/Server API will
|
|||
|
be able to query the room directory, and relatedly that the server will
|
|||
|
not share room directory information with other servers over federation.</p>
|
|||
|
<p>If your installation does not explicitly set these settings one way or
|
|||
|
the other and you want either setting to be <code>true</code> then it will
|
|||
|
necessary to update your homeserver configuration file accordingly.</p>

minutes to complete if there are a large number (more than a million or

<p>If you have configured a custom template directory with the

<code>email.template_dir</code> option, be aware that there are new templates
|

|
regarding registration and threepid management (see below) that must be
|

included.</p>
|

|
<ul>
|

<h2 id="3pid-verification-changes"><a class="header" href="#3pid-verification-changes">3pid verification changes</a></h2>
|

|
<p><strong>Note: As of this release, users will be unable to add phone numbers or
|
|||
|
email addresses to their accounts, without changes to the Synapse
|
|||
|
configuration. This includes adding an email address during
|
|||
|
registration.</strong></p>
|
|||
|
<p>It is possible for a user to associate an email address or phone number
|
|||
|
with their account, for a number of reasons:</p>
|
|||
|
<ul>
|
|||
|
<li>for use when logging in, as an alternative to the user id.</li>
|
|||
|
<li>in the case of email, as an alternative contact to help with account
|
|||
|
recovery.</li>
|
|||
|
<li>in the case of email, to receive notifications of missed messages.</li>
|
|||
|
</ul>
|
|||
|
<p>Before an email address or phone number can be added to a user's
|
|||
|
account, or before such an address is used to carry out a
|
|||
|
password-reset, Synapse must confirm the operation with the owner of the
|
|||
|
email address or phone number. It does this by sending an email or text
|
|||
|
giving the user a link or token to confirm receipt. This process is
|
|||
|
known as '3pid verification'. ('3pid', or 'threepid', stands for
|
|||
|
third-party identifier, and we use it to refer to external identifiers
|
|||
|
such as email addresses and phone numbers.)</p>
|
|||
|
<p>Previous versions of Synapse delegated the task of 3pid verification to
|
|||
|
an identity server by default. In most cases this server is <code>vector.im</code>
|
|||
|
or <code>matrix.org</code>.</p>
|
|||
|
<p>In Synapse 1.4.0, for security and privacy reasons, the homeserver will
|
|||
|
no longer delegate this task to an identity server by default. Instead,
|
|||
|
the server administrator will need to explicitly decide how they would
|
|||
|
like the verification messages to be sent.</p>
|
|||
|
<p>In the medium term, the <code>vector.im</code> and <code>matrix.org</code> identity servers
|
|||
|
will disable support for delegated 3pid verification entirely. However,
|
|||
|
in order to ease the transition, they will retain the capability for a
|
|||
|
limited period. Delegated email verification will be disabled on Monday
|
|||
|
2nd December 2019 (giving roughly 2 months notice). Disabling delegated
|
|||
|
SMS verification will follow some time after that once SMS verification
|
|||
|
support lands in Synapse.</p>
|
|||
|
<p>Once delegated 3pid verification support has been disabled in the
|
|||
|
<code>vector.im</code> and <code>matrix.org</code> identity servers, all Synapse versions that
|
|||
|
depend on those instances will be unable to verify email and phone
|
|||
|
numbers through them. There are no imminent plans to remove delegated
|
|||
|
3pid verification from Sydent generally. (Sydent is the identity server
|
|||
|
project that backs the <code>vector.im</code> and <code>matrix.org</code> instances).</p>
|
|||
|
<h3 id="email-1"><a class="header" href="#email-1">Email</a></h3>
|
|||
|
<p>Following upgrade, to continue verifying email (e.g. as part of the
|
|||
|
registration process), admins can either:-</p>
|
|||
|
<ul>
|
|||
|
<li>Configure Synapse to use an email server.</li>
|
|||
|
<li>Run or choose an identity server which allows delegated email
|
|||
|
verification and delegate to it.</li>
|
|||
|
</ul>
|
|||
|
<h4 id="configure-smtp-in-synapse"><a class="header" href="#configure-smtp-in-synapse">Configure SMTP in Synapse</a></h4>
|
|||
|
<p>To configure an SMTP server for Synapse, modify the configuration
|
|||
|
section headed <code>email</code>, and be sure to have at least the
|
|||
|
<code>smtp_host, smtp_port</code> and <code>notif_from</code> fields filled out.</p>
|
|||
|
<p>You may also need to set <code>smtp_user</code>, <code>smtp_pass</code>, and
|
|||
|
<code>require_transport_security</code>.</p>
|
|||
|
<p>See the <a href="usage/configuration/homeserver_sample_config.html">sample configuration file</a>
|
|||

for more details on these settings.</p>
|
|||
|
<h4 id="delegate-email-to-an-identity-server"><a class="header" href="#delegate-email-to-an-identity-server">Delegate email to an identity server</a></h4>
|
|||
|
<p>Some admins will wish to continue using email verification as part of
|
|||
|
the registration process, but will not immediately have an appropriate
|
|||
|
SMTP server at hand.</p>
|
|||
|
<p>To this end, we will continue to support email verification delegation
|
|||
|
via the <code>vector.im</code> and <code>matrix.org</code> identity servers for two months.
|
|||
|
Support for delegated email verification will be disabled on Monday 2nd
|
|||
|
December.</p>
|
|||
|
<p>The <code>account_threepid_delegates</code> dictionary defines whether the
|
|||
|
homeserver should delegate an external server (typically an <a href="https://matrix.org/docs/spec/identity_service/r0.2.1">identity
|
|||
|
server</a>) to handle
|
|||
|
sending confirmation messages via email and SMS.</p>
|
|||
|
<p>So to delegate email verification, in <code>homeserver.yaml</code>, set
|
|||
|
<code>account_threepid_delegates.email</code> to the base URL of an identity
|
|||
|
server. For example:</p>
|
|||
|
<pre><code class="language-yaml">account_threepid_delegates:
|
|||
|
email: https://example.com # Delegate email sending to example.com
|
|||
|
</code></pre>
|
|||
|
<p>Note that <code>account_threepid_delegates.email</code> replaces the deprecated
|
|||
|
<code>email.trust_identity_server_for_password_resets</code>: if
|
|||
|
<code>email.trust_identity_server_for_password_resets</code> is set to <code>true</code>, and
|
|||
|
<code>account_threepid_delegates.email</code> is not set, then the first entry in
|
|||
|
<code>trusted_third_party_id_servers</code> will be used as the
|
|||
|
<code>account_threepid_delegate</code> for email. This is to ensure compatibility
|
|||
|
with existing Synapse installs that set up external server handling for
|
|||
|
these tasks before v1.4.0. If
|
|||
|
<code>email.trust_identity_server_for_password_resets</code> is <code>true</code> and no
|
|||
|
trusted identity server domains are configured, Synapse will report an
|
|||
|
error and refuse to start.</p>
|
|||
|
<p>If <code>email.trust_identity_server_for_password_resets</code> is <code>false</code> or
|
|||
|
absent and no <code>email</code> delegate is configured in
|
|||
|
<code>account_threepid_delegates</code>, then Synapse will send email verification
|
|||
|
messages itself, using the configured SMTP server (see above). that
|
|||
|
type.</p>
|
|||
|
<h3 id="phone-numbers"><a class="header" href="#phone-numbers">Phone numbers</a></h3>
|
|||
|
<p>Synapse does not support phone-number verification itself, so the only
|
|||
|
way to maintain the ability for users to add phone numbers to their
|
|||
|
accounts will be by continuing to delegate phone number verification to
|
|||
|
the <code>matrix.org</code> and <code>vector.im</code> identity servers (or another identity
|
|||
|
server that supports SMS sending).</p>
|
|||
|
<p>The <code>account_threepid_delegates</code> dictionary defines whether the
|
|||
|
homeserver should delegate an external server (typically an <a href="https://matrix.org/docs/spec/identity_service/r0.2.1">identity
|
|||
|
server</a>) to handle
|
|||
|
sending confirmation messages via email and SMS.</p>
|
|||
|
<p>So to delegate phone number verification, in <code>homeserver.yaml</code>, set
|
|||
|
<code>account_threepid_delegates.msisdn</code> to the base URL of an identity
|
|||
|
server. For example:</p>
|
|||
|
<pre><code class="language-yaml">account_threepid_delegates:
|
|||
|
msisdn: https://example.com # Delegate sms sending to example.com
|
|||
|
</code></pre>
|
|||
|
<p>The <code>matrix.org</code> and <code>vector.im</code> identity servers will continue to
|
|||
|
support delegated phone number verification via SMS until such time as
|
|||
|
it is possible for admins to configure their servers to perform phone
|
|||
|
number verification directly. More details will follow in a future
|
|||
|
release.</p>

<h2 id="rolling-back-to-v131"><a class="header" href="#rolling-back-to-v131">Rolling back to v1.3.1</a></h2>
|
|||
|
<p>If you encounter problems with v1.4.0, it should be possible to roll
|
|||
|
back to v1.3.1, subject to the following:</p>
|
|||
|
<ul>
|
|||
|
<li>
|
|||
|
<p>The 'room statistics' engine was heavily reworked in this release
|
|||
|
(see <a href="https://github.com/matrix-org/synapse/pull/5971">#5971</a>),
|
|||
|
including significant changes to the database schema, which are not
|
|||
|
easily reverted. This will cause the room statistics engine to stop
|
|||
|
updating when you downgrade.</p>
|
|||
|
<p>The room statistics are essentially unused in v1.3.1 (in future
|
|||
|
versions of Synapse, they will be used to populate the room
|
|||
|
directory), so there should be no loss of functionality. However,
|
|||
|
the statistics engine will write errors to the logs, which can be
|
|||
|
avoided by setting the following in <code>homeserver.yaml</code>:</p>
|
|||
|
<pre><code class="language-yaml">stats:
|
|||
|
enabled: false
|
|||
|
</code></pre>
|
|||
|
<p>Don't forget to re-enable it when you upgrade again, in preparation
|
|||
|
for its use in the room directory!</p>

|
3.6 or Python 3.7 are recommended as they have improved internal string
|

<h2 id="validation-of-tls-certificates"><a class="header" href="#validation-of-tls-certificates">Validation of TLS certificates</a></h2>
|
|||
|
<p>Synapse v1.0 is the first release to enforce validation of TLS
|
|||
|
certificates for the federation API. It is therefore essential that your
|
|||
|
certificates are correctly configured. See the
|
|||
|
<a href="MSC1711_certificates_FAQ.html">FAQ</a> for more information.</p>
|
|||
|
<p>Note, v1.0 installations will also no longer be able to federate with
|
|||
|
servers that have not correctly configured their certificates.</p>
|
|||
|
<p>In rare cases, it may be desirable to disable certificate checking: for
|
|||
|
example, it might be essential to be able to federate with a given
|
|||
|
legacy server in a closed federation. This can be done in one of two
|
|||
|
ways:-</p>
|
|||
|
<ul>
|
|||
|
<li>Configure the global switch <code>federation_verify_certificates</code> to
|
|||
|
<code>false</code>.</li>
|
|||
|
<li>Configure a whitelist of server domains to trust via
|
|||
|
<code>federation_certificate_verification_whitelist</code>.</li>
|
|||
|
</ul>
|
|||
|
<p>See the <a href="usage/configuration/homeserver_sample_config.html">sample configuration file</a>

for more details on these settings.</p>
|
|||
|
<h2 id="email-2"><a class="header" href="#email-2">Email</a></h2>
|
|||
|
<p>When a user requests a password reset, Synapse will send an email to the
|
|||
|
user to confirm the request.</p>
|
|||
|
<p>Previous versions of Synapse delegated the job of sending this email to
|
|||
|
an identity server. If the identity server was somehow malicious or
|
|||
|
became compromised, it would be theoretically possible to hijack an
|
|||
|
account through this means.</p>
|
|||
|
<p>Therefore, by default, Synapse v1.0 will send the confirmation email
|
|||
|
itself. If Synapse is not configured with an SMTP server, password reset
|
|||
|
via email will be disabled.</p>
|
|||
|
<p>To configure an SMTP server for Synapse, modify the configuration
|
|||
|
section headed <code>email</code>, and be sure to have at least the <code>smtp_host</code>,
|
|||
|
<code>smtp_port</code> and <code>notif_from</code> fields filled out. You may also need to set
|
|||
|
<code>smtp_user</code>, <code>smtp_pass</code>, and <code>require_transport_security</code>.</p>
|
|||
|
<p>If you are absolutely certain that you wish to continue using an
|
|||
|
identity server for password resets, set
|
|||
|
<code>trust_identity_server_for_password_resets</code> to <code>true</code>.</p>
|
|||
|

<h2 id="new-email-templates"><a class="header" href="#new-email-templates">New email templates</a></h2>
|

<p>Some new templates have been added to the default template directory for the purpose of

|
the homeserver sending its own password reset emails. If you have configured a
|
|||
|
custom <code>template_dir</code> in your Synapse config, these files will need to be added.</p>
|
|||
|
<p><code>password_reset.html</code> and <code>password_reset.txt</code> are HTML and plain text
|
|||
|
templates respectively that contain the contents of what will be emailed
|
|||
|
to the user upon attempting to reset their password via email.
|
|||
|
<code>password_reset_success.html</code> and <code>password_reset_failure.html</code> are HTML
|
|||
|
files that the content of which (assuming no redirect URL is set) will
|
|||
|
be shown to the user after they attempt to click the link in the email
|

|
<p>Please be aware that, before Synapse v1.0 is released around March 2019,
|

|
<li>
|
|||
|
<p>This release is the first to fully support Python 3. Synapse will
|
|||
|
now run on Python versions 3.5, or 3.6 (as well as 2.7). We
|
|||
|
recommend switching to Python 3, as it has been shown to give
|
|||
|
performance improvements.</p>
|
|||
|
<p>For users who have installed Synapse into a virtualenv, we recommend
|
|||
|
doing this by creating a new virtualenv. For example:</p>
|
|||
|
<pre><code>virtualenv -p python3 ~/synapse/env3
|
|||
|
source ~/synapse/env3/bin/activate
|
|||
|
pip install matrix-synapse
|
|||
|
</code></pre>
|
|||
|
<p>You can then start synapse as normal, having activated the new
|
|||
|
virtualenv:</p>
|
|||
|
<pre><code>cd ~/synapse
|
|||
|
source env3/bin/activate
|
|||
|
synctl start
|
|||
|
</code></pre>
|
|||
|
<p>Users who have installed from distribution packages should see the
|
|||
|
relevant package documentation. See below for notes on Debian
|
|||
|
packages.</p>
|
|||
|
<ul>
|
|||
|
<li>
|
|||
|
<p>When upgrading to Python 3, you <strong>must</strong> make sure that your log
|
|||
|
files are configured as UTF-8, by adding <code>encoding: utf8</code> to the
|
|||
|
<code>RotatingFileHandler</code> configuration (if you have one) in your
|
|||
|
<code><server>.log.config</code> file. For example, if your <code>log.config</code>
|
|||
|
file contains:</p>
|
|||
|
<pre><code>handlers:
|
|||
|
file:
|
|||
|
class: logging.handlers.RotatingFileHandler
|
|||
|
formatter: precise
|
|||
|
filename: homeserver.log
|
|||
|
maxBytes: 104857600
|
|||
|
backupCount: 10
|
|||
|
filters: [context]
|

|
|||
|
formatter: precise
|
|||
|
filters: [context]
|
|||
|
</code></pre>
|
|||
|
<p>Then you should update this to be:</p>

<p>We are also making available Debian packages which will run Synapse
|

|
on Python 3. You can switch to these packages with
|

|
<code>apt-get install matrix-synapse-py3</code>, however, please read
|
|||
|
<a href="https://github.com/matrix-org/synapse/blob/release-v0.34.0/debian/NEWS">debian/NEWS</a>
|
|||
|
before doing so. The existing <code>matrix-synapse</code> packages will
|

|
continue to use Python 2 for the time being.</p>

<p>This release removes the <code>riot.im</code> from the default list of trusted
|
|||
|
identity servers.</p>
|
|||
|
<p>If <code>riot.im</code> is in your homeserver's list of
|
|||
|
<code>trusted_third_party_id_servers</code>, you should remove it. It was added
|
|||
|
in case a hypothetical future identity server was put there. If you

don't remove it, users may be unable to deactivate their accounts.</p>

<p>This release no longer installs the (unmaintained) Matrix Console
|
|||
|
web client as part of the default installation. It is possible to
|
|||
|
re-enable it by installing it separately and setting the
|
|||
|
<code>web_client_location</code> config option, but please consider switching
|
|||
|
to another client.</p>

<p>This release removes the example email notification templates from
|
|||
|
<code>res/templates</code> (they are now internal to the python package). This
|
|||
|
should only affect you if you (a) deploy your Synapse instance from a
|
|||
|
git checkout or a github snapshot URL, and (b) have email notifications
|
|||
|
enabled.</p>
|
|||
|
<p>If you have email notifications enabled, you should ensure that
|
|||
|
<code>email.template_dir</code> is either configured to point at a directory where
|
|||
|
you have installed customised templates, or leave it unset to use the
|
|||
|
default templates.</p>

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

<p>If you want to use the new URL previewing API
|

in the config and update your dependencies dependencies. See README.rst

|
matrix.org, and requires that administrators explictly opt in or out by
|
|||
|
setting the <code>report_stats</code> option to either <code>true</code> or <code>false</code>.</p>
|
|||
|
<p>We would really appreciate it if you could help our project out by
|
|||
|
reporting anonymized usage statistics from your homeserver. Only very
|
|||
|
basic aggregate data (e.g. number of users) will be reported, but it
|
|||
|
helps us to track the growth of the Matrix community, and helps us to
|
|||
|
make Matrix a success, as well as to convince other networks that they
|
|||
|
should peer with us.</p>

|
<p>Application services have had a breaking API change in this version.</p>
|
|||
|
<p>They can no longer register themselves with a home server using the AS
|
|||
|
HTTP API. This decision was made because a compromised application
|
|||
|
service with free reign to register any regex in effect grants full
|
|||
|
read/write access to the home server if a regex of <code>.*</code> is used. An
|
|||
|
attack where a compromised AS re-registers itself with <code>.*</code> was deemed
|
|||
|
too big of a security risk to ignore, and so the ability to register
|
|||
|
with the HS remotely has been removed.</p>
|
|||
|
<p>It has been replaced by specifying a list of application service
|
|||
|
registrations in <code>homeserver.yaml</code>:</p>
|
|||
|
<pre><code>app_service_config_files: ["registration-01.yaml", "registration-02.yaml"]
|
|||
|
</code></pre>
|
|||
|
<p>Where <code>registration-01.yaml</code> looks like:</p>
|
|||
|
<pre><code>url: <String> # e.g. "https://my.application.service.com"
|
|||
|
as_token: <String>
|

sender_localpart: <String> # This is a new field which denotes the user_id localpart when using the AS token

<p>This update includes a change to the database schema. To upgrade you
|
|||
|
first need to upgrade the database by running:</p>
|
|||
|
<pre><code>python scripts/upgrade_db_to_v0.6.0.py <db> <server_name> <signing_key>
|
|||
|
</code></pre>
|
|||
|
<p>Where [<db>]{.title-ref} is the location of the database,
|
|||
|
[<server_name>]{.title-ref} is the server name as specified in the
|
|||
|
synapse configuration, and [<signing_key>]{.title-ref} is the location
|
|||
|
of the signing key as specified in the synapse configuration.</p>
|
|||
|
<p>This may take some time to complete. Failures of signatures and content
|
|||
|
hashes can safely be ignored.</p>
|
|||
|
<h1 id="upgrading-to-v051"><a class="header" href="#upgrading-to-v051">Upgrading to v0.5.1</a></h1>
|
|||
|
<p>Depending on precisely when you installed v0.5.0 you may have ended up
|
|||
|
with a stale release of the reference matrix webclient installed as a
|
|||
|
python module. To uninstall it and ensure you are depending on the
|
|||
|
latest module, please run:</p>
|
|||
|
<pre><code>$ pip uninstall syweb
|
|||
|
</code></pre>
|
|||
|
<h1 id="upgrading-to-v050"><a class="header" href="#upgrading-to-v050">Upgrading to v0.5.0</a></h1>
|
|||
|
<p>The webclient has been split out into a seperate repository/pacakage in
|
|||
|
this release. Before you restart your homeserver you will need to pull
|
|||
|
in the webclient package by running:</p>
|
|||
|
<pre><code>python setup.py develop --user
|
|||
|
</code></pre>
|
|||
|
<p>This release completely changes the database schema and so requires
|
|||
|
upgrading it before starting the new version of the homeserver.</p>
|
|||
|
<p>The script "database-prepare-for-0.5.0.sh" should be used to upgrade
|
|||
|
the database. This will save all user information, such as logins and
|
|||
|
profiles, but will otherwise purge the database. This includes messages,
|
|||
|
which rooms the home server was a member of and room alias mappings.</p>
|
|||
|
<p>If you would like to keep your history, please take a copy of your
|
|||
|
database file and ask for help in #matrix:matrix.org. The upgrade
|
|||
|
process is, unfortunately, non trivial and requires human intervention
|
|||
|
to resolve any resulting conflicts during the upgrade process.</p>
|
|||
|
<p>Before running the command the homeserver should be first completely
|
|||
|
shutdown. To run it, simply specify the location of the database, e.g.:</p>
|
|||
|
<blockquote>
|
|||
|
<p>./scripts/database-prepare-for-0.5.0.sh "homeserver.db"</p>
|
|||
|
</blockquote>
|
|||
|
<p>Once this has successfully completed it will be safe to restart the
|
|||
|
homeserver. You may notice that the homeserver takes a few seconds
|
|||
|
longer to restart than usual as it reinitializes the database.</p>
|
|||
|
<p>On startup of the new version, users can either rejoin remote rooms
|
|||
|
using room aliases or by being reinvited. Alternatively, if any other
|
|||
|
homeserver sends a message to a room that the homeserver was previously
|
|||
|
in the local HS will automatically rejoin the room.</p>
|
|||
|
<h1 id="upgrading-to-v040"><a class="header" href="#upgrading-to-v040">Upgrading to v0.4.0</a></h1>
|
|||
|
<p>This release needs an updated syutil version. Run:</p>
|
|||
|
<pre><code>python setup.py develop
|
|||
|
</code></pre>
|
|||
|
<p>You will also need to upgrade your configuration as the signing key
|
|||
|
format has changed. Run:</p>
|
|||
|
<pre><code>python -m synapse.app.homeserver --config-path <CONFIG> --generate-config
|
|||
|
</code></pre>
|
|||
|
<h1 id="upgrading-to-v030"><a class="header" href="#upgrading-to-v030">Upgrading to v0.3.0</a></h1>
|
|||
|
<p>This registration API now closely matches the login API. This introduces
|
|||
|
a bit more backwards and forwards between the HS and the client, but
|
|||
|
this improves the overall flexibility of the API. You can now GET on
|
|||
|
/register to retrieve a list of valid registration flows. Upon choosing
|
|||
|
one, they are submitted in the same way as login, e.g:</p>
|
|||
|
<pre><code>{
|
|||
|
type: m.login.password,
|
|||
|
user: foo,
|
|||
|
password: bar
|
|||
|
}
|
|||
|
</code></pre>
|
|||
|
<p>The default HS supports 2 flows, with and without Identity Server email
|
|||
|
authentication. Enabling captcha on the HS will add in an extra step to
|
|||
|
all flows: <code>m.login.recaptcha</code> which must be completed before you can
|
|||
|
transition to the next stage. There is a new login type:
|
|||
|
<code>m.login.email.identity</code> which contains the <code>threepidCreds</code> key which
|
|||
|
were previously sent in the original register request. For more
|
|||
|
information on this, see the specification.</p>
|
|||
|
<h2 id="web-client"><a class="header" href="#web-client">Web Client</a></h2>
|
|||
|
<p>The VoIP specification has changed between v0.2.0 and v0.3.0. Users
|
|||
|
should refresh any browser tabs to get the latest web client code. Users
|
|||
|
on v0.2.0 of the web client will not be able to call those on v0.3.0 and
|
|||
|
vice versa.</p>
|
|||
|
<h1 id="upgrading-to-v020"><a class="header" href="#upgrading-to-v020">Upgrading to v0.2.0</a></h1>
|
|||
|
<p>The home server now requires setting up of SSL config before it can run.
|
|||
|
To automatically generate default config use:</p>
|
|||
|
<pre><code>$ python synapse/app/homeserver.py \
|
|||
|
--server-name machine.my.domain.name \
|
|||
|
--bind-port 8448 \
|
|||
|
--config-path homeserver.config \
|
|||
|
--generate-config
|
|||
|
</code></pre>
|
|||
|
<p>This config can be edited if desired, for example to specify a different
|
|||
|
SSL certificate to use. Once done you can run the home server using:</p>
|
|||
|
<pre><code>$ python synapse/app/homeserver.py --config-path homeserver.config
|
|||
|
</code></pre>
|
|||
|
<p>See the README.rst for more information.</p>
|
|||
|
<p>Also note that some config options have been renamed, including:</p>
|
|||
|
<ul>
|
|||
|
<li>"host" to "server-name"</li>
|
|||
|
<li>"database" to "database-path"</li>
|
|||
|
<li>"port" to "bind-port" and "unsecure-port"</li>

|

|
<p>This document was originally written to guide server admins through the upgrade
|
|||
|
path towards Synapse 1.0. Specifically,
|
|||
|
<a href="https://github.com/matrix-org/matrix-doc/blob/master/proposals/1711-x509-for-federation.md">MSC1711</a>
|
|||
|
required that all servers present valid TLS certificates on their federation
|
|||
|
API. Admins were encouraged to achieve compliance from version 0.99.0 (released
|
|||
|
in February 2019) ahead of version 1.0 (released June 2019) enforcing the
|
|||
|
certificate checks.</p>
|
|||
|
<p>Much of what follows is now outdated since most admins will have already
|
|||
|
upgraded, however it may be of use to those with old installs returning to the
|
|||
|
project.</p>
|
|||
|
<p>If you are setting up a server from scratch you almost certainly should look at
|
|||
|
the <a href="setup/installation.html">installation guide</a> instead.</p>
|
|||
|
<h2 id="introduction-1"><a class="header" href="#introduction-1">Introduction</a></h2>
|
|||
|
<p>The goal of Synapse 0.99.0 is to act as a stepping stone to Synapse 1.0.0. It
|
|||
|
supports the r0.1 release of the server to server specification, but is
|
|||
|
compatible with both the legacy Matrix federation behaviour (pre-r0.1) as well
|
|||
|
as post-r0.1 behaviour, in order to allow for a smooth upgrade across the
|
|||
|
federation.</p>
|
|||
|
<p>The most important thing to know is that Synapse 1.0.0 will require a valid TLS
|
|||
|
certificate on federation endpoints. Self signed certificates will not be
|
|||
|
sufficient.</p>
|
|||
|
<p>Synapse 0.99.0 makes it easy to configure TLS certificates and will
|
|||
|
interoperate with both >= 1.0.0 servers as well as existing servers yet to
|
|||
|
upgrade.</p>
|
|||
|
<p><strong>It is critical that all admins upgrade to 0.99.0 and configure a valid TLS
|
|||
|
certificate.</strong> Admins will have 1 month to do so, after which 1.0.0 will be
|
|||
|
released and those servers without a valid certificate will not longer be able
|
|||
|
to federate with >= 1.0.0 servers.</p>
|
|||
|

<p><strong>10th June 2019 - Synapse 1.0.0 is released</strong></p>
|
|||
|
<p>1.0.0 is scheduled for release on 10th June. In
|
|||
|
accordance with the the <a href="https://matrix.org/docs/spec/server_server/r0.1.0.html">S2S spec</a>
|
|||
|
1.0.0 will enforce certificate validity. This means that any homeserver without a
|
|||
|
valid certificate after this point will no longer be able to federate with
|
|||
|
1.0.0 servers.</p>

|
|||
|
<p>In this case, your <code>server_name</code> points to the host where your Synapse is
|
|||
|
running. There is no need to create a <code>.well-known</code> URI or an SRV record, but
|
|||
|
you will need to give Synapse a valid, signed, certificate.</p>
|
|||
|
<h3 id="if-you-do-have-an-srv-record-currently"><a class="header" href="#if-you-do-have-an-srv-record-currently">If you do have an SRV record currently</a></h3>
|
|||
|
<p>If you are using an SRV record, your matrix domain (<code>server_name</code>) may not
|
|||
|
point to the same host that your Synapse is running on (the 'target
|
|||
|
domain'). (If it does, you can follow the recommendation above; otherwise, read
|
|||
|
on.)</p>
|
|||
|
<p>Let's assume that your <code>server_name</code> is <code>example.com</code>, and your Synapse is
|
|||
|
hosted at a target domain of <code>customer.example.net</code>. Currently you should have
|
|||
|
an SRV record which looks like:</p>
|
|||
|
<pre><code>_matrix._tcp.example.com. IN SRV 10 5 8000 customer.example.net.
|
|||
|
</code></pre>
|
|||
|
<p>In this situation, you have three choices for how to proceed:</p>
|
|||
|
<h4 id="option-1-give-synapse-a-certificate-for-your-matrix-domain"><a class="header" href="#option-1-give-synapse-a-certificate-for-your-matrix-domain">Option 1: give Synapse a certificate for your matrix domain</a></h4>
|
|||
|
<p>Synapse 1.0 will expect your server to present a TLS certificate for your
|
|||
|
<code>server_name</code> (<code>example.com</code> in the above example). You can achieve this by acquiring a
|
|||
|
certificate for the <code>server_name</code> yourself (for example, using <code>certbot</code>), and giving it
|
|||
|
and the key to Synapse via <code>tls_certificate_path</code> and <code>tls_private_key_path</code>.</p>
|
|||
|
<h4 id="option-2-run-synapse-behind-a-reverse-proxy"><a class="header" href="#option-2-run-synapse-behind-a-reverse-proxy">Option 2: run Synapse behind a reverse proxy</a></h4>
|
|||
|
<p>If you have an existing reverse proxy set up with correct TLS certificates for
|
|||
|
your domain, you can simply route all traffic through the reverse proxy by
|
|||
|
updating the SRV record appropriately (or removing it, if the proxy listens on
|
|||
|
8448).</p>
|
|||
|
<p>See <a href="reverse_proxy.html">the reverse proxy documentation</a> for information on setting up a
|
|||
|
reverse proxy.</p>

|
|||
|
<p>This will allow you to keep Synapse on a separate domain, without having to
|
|||
|
give it a certificate for the matrix domain.</p>
|
|||
|
<p>You can do this with a <code>.well-known</code> file as follows:</p>
|
|||
|
<ol>
|
|||
|
<li>
|
|||
|
<p>Keep the SRV record in place - it is needed for backwards compatibility
|
|||
|
with Synapse 0.34 and earlier.</p>
|
|||
|
</li>
|
|||
|
<li>
|
|||
|
<p>Give Synapse a certificate corresponding to the target domain
|
|||
|
(<code>customer.example.net</code> in the above example). You can do this by acquire a
|
|||
|
certificate for the target domain and giving it to Synapse via <code>tls_certificate_path</code>
|
|||
|
and <code>tls_private_key_path</code>.</p>
|
|||
|
</li>
|
|||
|
<li>
|
|||
|
<p>Restart Synapse to ensure the new certificate is loaded.</p>
|
|||
|
</li>
|
|||
|
<li>
|
|||
|
<p>Arrange for a <code>.well-known</code> file at
|
|||
|
<code>https://<server_name>/.well-known/matrix/server</code> with contents:</p>
|
|||
|
<pre><code class="language-json">{"m.server": "<target server name>"}
|
|||
|
</code></pre>
|
|||
|
<p>where the target server name is resolved as usual (i.e. SRV lookup, falling
|
|||
|
back to talking to port 8448).</p>
|
|||
|
<p>In the above example, where synapse is listening on port 8000,
|
|||
|
<code>https://example.com/.well-known/matrix/server</code> should have <code>m.server</code> set to one of:</p>
|
|||
|
<ol>
|
|||
|
<li>
|
|||
|
<p><code>customer.example.net</code> ─ with a SRV record on
|
|||
|
<code>_matrix._tcp.customer.example.com</code> pointing to port 8000, or:</p>
|
|||
|
</li>
|
|||
|
<li>
|
|||
|
<p><code>customer.example.net</code> ─ updating synapse to listen on the default port
|
|||
|
8448, or:</p>
|
|||
|
</li>
|
|||
|
<li>
|
|||
|
<p><code>customer.example.net:8000</code> ─ ensuring that if there is a reverse proxy
|
|||
|
on <code>customer.example.net:8000</code> it correctly handles HTTP requests with
|
|||
|
Host header set to <code>customer.example.net:8000</code>.</p>

|
|||
|
<p>If your homeserver listens on the default federation port (8448), and your
|
|||
|
<code>server_name</code> points to the host that your homeserver runs on, you do not need an
|
|||
|
SRV record or <code>.well-known/matrix/server</code> URI.</p>
|
|||
|
<p>For instance, if you registered <code>example.com</code> and pointed its DNS A record at a
|
|||
|
fresh Upcloud VPS or similar, you could install Synapse 0.99 on that host,
|
|||
|
giving it a server_name of <code>example.com</code>, and it would automatically generate a
|
|||
|
valid TLS certificate for you via Let's Encrypt and no SRV record or
|
|||
|
<code>.well-known</code> URI would be needed.</p>
|
|||
|
<p>This is the common case, although you can add an SRV record or
|
|||
|
<code>.well-known/matrix/server</code> URI for completeness if you wish.</p>
|
|||
|
<p><strong>However</strong>, if your server does not listen on port 8448, or if your <code>server_name</code>
|
|||
|
does not point to the host that your homeserver runs on, you will need to let
|
|||
|
other servers know how to find it.</p>
|
|||
|
<p>In this case, you should see <a href="MSC1711_certificates_FAQ.html#if-you-do-have-an-srv-record-currently">"If you do have an SRV record
|
|||
|
currently"</a> above.</p>
|
|||
|
<h3 id="can-i-still-use-an-srv-record"><a class="header" href="#can-i-still-use-an-srv-record">Can I still use an SRV record?</a></h3>
|
|||
|
<p>Firstly, if you didn't need an SRV record before (because your server is
|
|||
|
listening on port 8448 of your server_name), you certainly don't need one now:
|
|||
|
the defaults are still the same.</p>
|
|||
|
<p>If you previously had an SRV record, you can keep using it provided you are
|
|||
|
able to give Synapse a TLS certificate corresponding to your server name. For
|
|||
|
example, suppose you had the following SRV record, which directs matrix traffic
|
|||
|
for example.com to matrix.example.com:443:</p>
|
|||
|
<pre><code>_matrix._tcp.example.com. IN SRV 10 5 443 matrix.example.com
|
|||
|
</code></pre>
|
|||
|
<p>In this case, Synapse must be given a certificate for example.com - or be
|
|||
|
configured to acquire one from Let's Encrypt.</p>
|
|||
|
<p>If you are unable to give Synapse a certificate for your server_name, you will
|
|||
|
also need to use a .well-known URI instead. However, see also "I have created a
|
|||
|
.well-known URI. Do I still need an SRV record?".</p>
|
|||
|
<h3 id="i-have-created-a-well-known-uri-do-i-still-need-an-srv-record"><a class="header" href="#i-have-created-a-well-known-uri-do-i-still-need-an-srv-record">I have created a .well-known URI. Do I still need an SRV record?</a></h3>
|
|||
|
<p>As of Synapse 0.99, Synapse will first check for the existence of a <code>.well-known</code>
|
|||
|
URI and follow any delegation it suggests. It will only then check for the
|
|||
|
existence of an SRV record.</p>
|
|||
|
<p>That means that the SRV record will often be redundant. However, you should
|
|||
|
remember that there may still be older versions of Synapse in the federation
|
|||
|
which do not understand <code>.well-known</code> URIs, so if you removed your SRV record you
|
|||
|
would no longer be able to federate with them.</p>
|
|||
|
<p>It is therefore best to leave the SRV record in place for now. Synapse 0.34 and
|
|||
|
earlier will follow the SRV record (and not care about the invalid
|
|||
|
certificate). Synapse 0.99 and later will follow the .well-known URI, with the
|
|||
|
correct certificate chain.</p>

|||

|
|||
|
<p>We have always wanted Matrix servers to be as easy to set up as possible, and
|
|||
|
so back when we started federation in 2014 we didn't want admins to have to go
|
|||
|
through the cumbersome process of buying a valid TLS certificate to run a
|
|||
|
server. This was before Let's Encrypt came along and made getting a free and
|
|||
|
valid TLS certificate straightforward. So instead, we adopted a system based on
|
|||
|
<a href="https://en.wikipedia.org/wiki/Convergence_(SSL)">Perspectives</a>: an approach
|
|||
|
where you check a set of "notary servers" (in practice, homeservers) to vouch
|
|||
|
for the validity of a certificate rather than having it signed by a CA. As long
|
|||
|
as enough different notaries agree on the certificate's validity, then it is
|
|||
|
trusted.</p>
|
|||
|
<p>However, in practice this has never worked properly. Most people only use the
|
|||
|
default notary server (matrix.org), leading to inadvertent centralisation which
|
|||
|
we want to eliminate. Meanwhile, we never implemented the full consensus
|
|||
|
algorithm to query the servers participating in a room to determine consensus
|
|||
|
on whether a given certificate is valid. This is fiddly to get right
|
|||
|
(especially in face of sybil attacks), and we found ourselves questioning
|
|||
|
whether it was worth the effort to finish the work and commit to maintaining a
|
|||
|
secure certificate validation system as opposed to focusing on core Matrix
|
|||
|
development.</p>
|
|||
|
<p>Meanwhile, Let's Encrypt came along in 2016, and put the final nail in the
|
|||
|
coffin of the Perspectives project (which was already pretty dead). So, the
|
|||
|
Spec Core Team decided that a better approach would be to mandate valid TLS
|
|||
|
certificates for federation alongside the rest of the Web. More details can be
|
|||
|
found in
|
|||
|
<a href="https://github.com/matrix-org/matrix-doc/blob/master/proposals/1711-x509-for-federation.md#background-the-failure-of-the-perspectives-approach">MSC1711</a>.</p>
|
|||
|
<p>This results in a breaking change, which is disruptive, but absolutely critical
|
|||
|
for the security model. However, the existence of Let's Encrypt as a trivial
|
|||
|
way to replace the old self-signed certificates with valid CA-signed ones helps
|
|||
|
smooth things over massively, especially as Synapse can now automate Let's
|
|||
|
Encrypt certificate generation if needed.</p>

|
|||
|
<p>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.</p>

|
|||
|
<p>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.</p>
|
|||
|
<p>See <a href="reverse_proxy.html">the reverse proxy documentation</a> for information on setting up a
|
|||
|
reverse proxy.</p>

<h3 id="do-i-still-need-to-give-my-tls-certificates-to-synapse-if-i-am-using-a-reverse-proxy-1"><a class="header" href="#do-i-still-need-to-give-my-tls-certificates-to-synapse-if-i-am-using-a-reverse-proxy-1">Do I still need to give my TLS certificates to Synapse if I am using a reverse proxy?</a></h3>
|
|||
|
<p>Practically speaking, this is no longer necessary.</p>
|
|||
|
<p>If you are using a reverse proxy for all of your TLS traffic, then you can set
|
|||
|
<code>no_tls: True</code>. 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 <code>matrix.org</code>, which is on 0.99.0.</p>
|
|||
|
<p>However, there is a bug in Synapse 0.99.0
|
|||
|
<a href="https://github.com/matrix-org/synapse/issues/4554">4554</a> which prevents
|
|||
|
Synapse from starting if you do not give it a TLS certificate. To work around
|
|||
|
this, you can give it any TLS certificate at all. This will be fixed soon.</p>
|

|
<h3 id="do-i-need-the-same-certificate-for-the-client-and-federation-port-1"><a class="header" href="#do-i-need-the-same-certificate-for-the-client-and-federation-port-1">Do I need the same certificate for the client and federation port?</a></h3>
|
|||
|
<p>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.</p>

|

<p>Synapse will reload the keys and certificates when it receives a SIGHUP - for
|

example <code>kill -HUP $(cat homeserver.pid)</code>. Alternatively, simply restart
|
|||
|
Synapse, though this will result in downtime while it restarts.</p>

|
|||
|
<p>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.</p>
|
|||
|
<p>The <code>server_name</code> configured in the Synapse configuration file (often
|
|||
|
<code>homeserver.yaml</code>) defines how resources (users, rooms, etc.) will be
|
|||
|
identified (eg: <code>@user:example.com</code>, <code>#room:example.com</code>). 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 <code>server_name</code> to match your machine's public DNS hostname.</p>
|
|||
|
<p>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 <a href="reverse_proxy.html">the reverse proxy documentation</a> for instructions
|
|||
|
on how to correctly set one up.</p>
|
|||
|
<p>In some cases you might not want to run Synapse on the machine that has
|
|||
|
the <code>server_name</code> 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 <code>@user:example.com</code>, but you want to run
|
|||
|
Synapse on <code>synapse.example.com</code> on port 443. This can be done using
|
|||
|
delegation, which allows an admin to control where federation traffic should
|
|||
|
be sent. See <a href="delegate.html">the delegation documentation</a> for instructions on how to set this up.</p>
|
|||
|
<p>Once federation has been configured, you should be able to join a room over
|
|||
|
federation. A good place to start is <code>#synapse:matrix.org</code> - a room for
|
|||
|
Synapse admins.</p>
|
|||
|
<h2 id="troubleshooting-3"><a class="header" href="#troubleshooting-3">Troubleshooting</a></h2>
|
|||
|
<p>You can use the <a href="https://matrix.org/federationtester">federation tester</a>
|
|||
|
to check if your homeserver is configured correctly. Alternatively try the
|
|||
|
<a href="https://matrix.org/federationtester/api/report?server_name=DOMAIN">JSON API used by the federation tester</a>.
|
|||
|
Note that you'll have to modify this URL to replace <code>DOMAIN</code> with your
|
|||
|
<code>server_name</code>. Hitting the API directly provides extra detail.</p>
|
|||
|
<p>The typical failure mode for federation is that when the server tries to join
|
|||
|
a room, it is rejected with "401: Unauthorized". Generally this means that other
|
|||
|
servers in the room could not access yours. (Joining a room over federation is
|
|||
|
a complicated dance which requires connections in both directions).</p>
|
|||
|
<p>Another common problem is that people on other servers can't join rooms that
|
|||
|
you invite them to. This can be caused by an incorrectly-configured reverse
|
|||
|
proxy: see <a href="reverse_proxy.html">the reverse proxy documentation</a> for instructions on how
|
|||
|
to correctly configure a reverse proxy.</p>

|
|||
|
<p><strong>HTTP <code>308 Permanent Redirect</code> redirects are not followed</strong>: Due to missing features
|
|||
|
in the HTTP library used by Synapse, 308 redirects are currently not followed by
|
|||
|
federating servers, which can cause <code>M_UNKNOWN</code> or <code>401 Unauthorized</code> errors. This
|
|||
|
may affect users who are redirecting apex-to-www (e.g. <code>example.com</code> -> <code>www.example.com</code>),
|
|||
|
and especially users of the Kubernetes <em>Nginx Ingress</em> module, which uses 308 redirect
|
|||
|
codes by default. For those Kubernetes users, <a href="https://stackoverflow.com/a/52617528/5096871">this Stackoverflow post</a>
|
|||
|
might be helpful. For other users, switching to a <code>301 Moved Permanently</code> code may be
|
|||
|
an option. 308 redirect codes will be supported properly in a future
|
|||
|
release of Synapse.</p>

<p>Below is a sample homeserver configuration file. The homeserver configuration file

|
# This is a YAML file: see [1] for a quick introduction. Note in particular

## Modules ##
|
|||
|
|
|||
|
# Server admins can expand Synapse's functionality with external modules.
|
|||
|
#
|
|||
|
# See https://matrix-org.github.io/synapse/latest/modules.html for more
|
|||
|
# documentation on how to configure or create custom modules for Synapse.
|
|||
|
#
|
|||
|
modules:
|
|||
|
# - module: my_super_module.MySuperClass
|
|||
|
# config:
|
|||
|
# do_thing: true
|
|||
|
# - module: my_other_super_module.SomeClass
|
|||
|
# config: {}
|
|||
|
|
|||
|
|
|||
|
## Server ##
|
|||
|
|
|||
|
# The public-facing domain of the server
|
|||
|
#
|
|||
|
# The server_name name will appear at the end of usernames and room addresses
|
|||
|
# created on this server. For example if the server_name was example.com,
|
|||
|
# usernames on this server would be in the format @user:example.com
|
|||
|
#
|
|||
|
# In most cases you should avoid using a matrix specific subdomain such as
|
|||
|
# matrix.example.com or synapse.example.com as the server_name for the same
|
|||
|
# reasons you wouldn't use user@email.example.com as your email address.
|
|||
|
# See https://matrix-org.github.io/synapse/latest/delegate.html
|
|||
|
# for information on how to host Synapse on a subdomain while preserving
|
|||
|
# a clean server_name.
|
|||
|
#
|
|||
|
# The server_name cannot be changed later so it is important to
|
|||
|
# configure this correctly before you start Synapse. It should be all
|
|||
|
# lowercase and may contain an explicit port.
|
|||
|
# Examples: matrix.org, localhost:8080
|

|
#
|

|
# This option can be also set to the filesystem path to the web client
|

|
# which will be served at /_matrix/client/ if 'webclient' is configured
|

|

# events in every room daily.
|
|||
|
#
|

|
# Each job's configuration defines which range of message lifetimes the job
|
|||
|
# takes care of. For example, if 'shortest_max_lifetime' is '2d' and
|
|||
|
# 'longest_max_lifetime' is '3d', the job will handle purging expired events in
|
|||
|
# rooms whose state defines a 'max_lifetime' that's both higher than 2 days, and
|
|||
|
# lower than or equal to 3 days. Both the minimum and the maximum value of a
|
|||
|
# range are optional, e.g. a job with no 'shortest_max_lifetime' and a
|
|||
|
# 'longest_max_lifetime' of '3d' will handle every room with a retention policy
|
|||
|
# which 'max_lifetime' is lower than or equal to three days.
|
|||
|
#
|
|||
|
# The rationale for this per-job configuration is that some rooms might have a
|
|||
|
# retention policy with a low 'max_lifetime', where history needs to be purged
|
|||
|
# of outdated messages on a more frequent basis than for the rest of the rooms
|
|||
|
# (e.g. every 12h), but not want that purge to be performed by a job that's
|
|||
|
# iterating over every room it knows, which could be heavy on the server.
|
|||
|
#
|
|||
|
# If any purge job is configured, it is strongly recommended to have at least
|
|||
|
# a single job with neither 'shortest_max_lifetime' nor 'longest_max_lifetime'
|
|||
|
# set, or one job without 'shortest_max_lifetime' and one job without
|
|||
|
# 'longest_max_lifetime' set. Otherwise some rooms might be ignored, even if
|
|||
|
# 'allowed_lifetime_min' and 'allowed_lifetime_max' are set, because capping a
|
|||
|
# room's policy to these values is done after the policies are retrieved from
|

## Database ##
|
|||
|
|
|||
|
# The 'database' setting defines the database that synapse uses to store all of
|
|||
|
# its data.
|
|||
|
#
|
|||
|
# 'name' gives the database engine to use: either 'sqlite3' (for SQLite) or
|
|||
|
# 'psycopg2' (for PostgreSQL).
|
|||
|
#
|
|||
|
# 'txn_limit' gives the maximum number of transactions to run per connection
|
|||
|
# before reconnecting. Defaults to 0, which means no limit.
|
|||
|
#
|
|||
|
# '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
|
|||
|
# * for postgres: https://www.postgresql.org/docs/current/libpq-connect.html#LIBPQ-PARAMKEYWORDS
|

## Ratelimiting ##
|
|||
|
|
|||
|
# Ratelimiting settings for client actions (registration, login, messaging).
|
|||
|
#
|
|||
|
# Each ratelimiting configuration is made of two parameters:
|
|||
|
# - per_second: number of requests a client can send per second.
|
|||
|
# - burst_count: number of requests a client can send before being throttled.
|
|||
|
#
|
|||
|
# Synapse currently uses the following configurations:
|
|||
|
# - one for messages that ratelimits sending based on the account the client
|
|||
|
# is using
|
|||
|
# - one for registration that ratelimits registration requests based on the
|
|||
|
# client's IP address.
|
|||
|
# - one for checking the validity of registration tokens that ratelimits
|
|||
|
# requests based on the client's IP address.
|
|||
|
# - one for login that ratelimits login requests based on the client's IP
|
|||
|
# address.
|
|||
|
# - one for login that ratelimits login requests based on the account the
|
|||
|
# client is attempting to log into.
|
|||
|
# - one for login that ratelimits login requests based on the account the
|
|||
|
# client is attempting to log into, based on the amount of failed login
|
|||
|
# attempts for this account.
|
|||
|
# - one for ratelimiting redactions by room admins. If this is not explicitly
|
|||
|
# set then it uses the same ratelimiting as per rc_message. This is useful
|
|||
|
# to allow room admins to deal with abuse quickly.
|
|||
|
# - two for ratelimiting number of rooms a user can join, "local" for when
|
|||
|
# users are joining rooms the server is already in (this is cheap) vs
|
|||
|
# "remote" for when users are trying to join rooms not on the server (which
|
|||
|
# can be more expensive)
|
|||
|
# - one for ratelimiting how often a user or IP can attempt to validate a 3PID.
|
|||
|
# - two for ratelimiting how often invites can be sent in a room or to a
|
|||
|
# specific user.

|
|||
|
<p>A structured logging system can be useful when your logs are destined for a
|
|||
|
machine to parse and process. By maintaining its machine-readable characteristics,
|
|||
|
it enables more efficient searching and aggregations when consumed by software
|
|||
|
such as the "ELK stack".</p>
|
|||
|
<p>Synapse's structured logging system is configured via the file that Synapse's
|
|||
|
<code>log_config</code> config option points to. The file should include a formatter which
|
|||
|
uses the <code>synapse.logging.TerseJsonFormatter</code> class included with Synapse and a
|
|||
|
handler which uses the above formatter.</p>
|
|||
|
<p>There is also a <code>synapse.logging.JsonFormatter</code> option which does not include
|
|||
|
a timestamp in the resulting JSON. This is useful if the log ingester adds its
|
|||
|
own timestamp.</p>

<p>The above logging config will set Synapse as 'INFO' logging level by default,

|
<p>It is also possible to figure Synapse to log to a remote endpoint by using the
|

|
<code>synapse.logging.RemoteHandler</code> class included with Synapse. It takes the
|

|
following arguments:</p>
|
|||
|
<ul>
|
|||
|
<li><code>host</code>: Hostname or IP address of the log aggregator.</li>
|

|
<li><code>port</code>: Numerical port to contact on the host.</li>
|

|
<li><code>maximum_buffer</code>: (Optional, defaults to 1000) The maximum buffer size to allow.</li>

</ul>

<h2 id="upgrading-from-legacy-structured-logging-configuration"><a class="header" href="#upgrading-from-legacy-structured-logging-configuration">Upgrading from legacy structured logging configuration</a></h2>
|
|||
|
<p>Versions of Synapse prior to v1.23.0 included a custom structured logging
|
|||
|
configuration which is deprecated. It used a <code>structured: true</code> flag and
|
|||
|
configured <code>drains</code> instead of <code>handlers</code> and <code>formatters</code>.</p>
|
|||
|
<p>Synapse currently automatically converts the old configuration to the new
|
|||
|
configuration, but this will be removed in a future version of Synapse. The
|
|||
|
following reference can be used to update your configuration. Based on the drain
|
|||
|
<code>type</code>, we can pick a new handler:</p>
|
|||
|
<ol>
|
|||
|
<li>For a type of <code>console</code>, <code>console_json</code>, or <code>console_json_terse</code>: a handler
|
|||
|
with a class of <code>logging.StreamHandler</code> and a <code>stream</code> of <code>ext://sys.stdout</code>
|
|||
|
or <code>ext://sys.stderr</code> should be used.</li>
|
|||
|
<li>For a type of <code>file</code> or <code>file_json</code>: a handler of <code>logging.FileHandler</code> with
|
|||
|
a location of the file path should be used.</li>
|
|||
|
<li>For a type of <code>network_json_terse</code>: a handler of <code>synapse.logging.RemoteHandler</code>
|
|||
|
with the host and port should be used.</li>
|
|||
|
</ol>
|
|||
|
<p>Then based on the drain <code>type</code> we can pick a new formatter:</p>
|
|||
|
<ol>
|
|||
|
<li>For a type of <code>console</code> or <code>file</code> no formatter is necessary.</li>
|
|||
|
<li>For a type of <code>console_json</code> or <code>file_json</code>: a formatter of
|
|||
|
<code>synapse.logging.JsonFormatter</code> should be used.</li>
|
|||
|
<li>For a type of <code>console_json_terse</code> or <code>network_json_terse</code>: a formatter of
|
|||
|
<code>synapse.logging.TerseJsonFormatter</code> should be used.</li>
|
|||
|
</ol>
|
|||
|
<p>For each new handler and formatter they should be added to the logging configuration
|
|||
|
and then assigned to either a logger or the root logger.</p>

<p>The new logging configuration is a bit more verbose, but significantly more
|

flexible. It allows for configuration that were not previously possible, such as

|
sending plain logs over the network, or using different handlers for different
|

|
<p>Synapse uses parametrised templates to generate the content of emails it sends and
|
|||
|
webpages it shows to users.</p>
|
|||
|
<p>By default, Synapse will use the templates listed <a href="https://github.com/matrix-org/synapse/tree/master/synapse/res/templates">here</a>.
|
|||
|
Server admins can configure an additional directory for Synapse to look for templates
|
|||
|
in, allowing them to specify custom templates:</p>
|
|||
|
<pre><code class="language-yaml">templates:
|
|||
|
custom_templates_directory: /path/to/custom/templates/
|
|||
|
</code></pre>
|
|||
|
<p>If this setting is not set, or the files named below are not found within the directory,
|
|||
|
default templates from within the Synapse package will be used.</p>
|
|||
|
<p>Templates that are given variables when being rendered are rendered using <a href="https://jinja.palletsprojects.com/en/2.11.x/">Jinja 2</a>.
|
|||
|
Templates rendered by Jinja 2 can also access two functions on top of the functions
|
|||
|
already available as part of Jinja 2:</p>
|
|||
|
<pre><code class="language-python">format_ts(value: int, format: str) -> str
|
|||
|
</code></pre>
|
|||
|
<p>Formats a timestamp in milliseconds.</p>
|
|||
|
<p>Example: <code>reason.last_sent_ts|format_ts("%c")</code></p>
|
|||
|
<pre><code class="language-python">mxc_to_http(value: str, width: int, height: int, resize_method: str = "crop") -> str
|
|||
|
</code></pre>
|
|||
|
<p>Turns a <code>mxc://</code> URL for media content into an HTTP(S) one using the homeserver's
|
|||
|
<code>public_baseurl</code> configuration setting as the URL's base.</p>

|

|
<p>Synapse supports multiple methods of authenticating users, either out-of-the-box or through custom pluggable
|
|||
|
authentication modules.</p>
|
|||
|
<p>Included in Synapse is support for authenticating users via:</p>
|
|||
|
<ul>
|
|||
|
<li>A username and password.</li>
|
|||
|
<li>An email address and password.</li>
|
|||
|
<li>Single Sign-On through the SAML, Open ID Connect or CAS protocols.</li>
|
|||
|
<li>JSON Web Tokens.</li>
|
|||
|
<li>An administrator's shared secret.</li>
|
|||
|
</ul>
|
|||
|
<p>Synapse can additionally be extended to support custom authentication schemes through optional "password auth provider"
|
|||
|
modules.</p>

<div id="chapter_begin" style="break-before: page; page-break-before: always;"></div><h1 id="configuring-synapse-to-authenticate-against-an-openid-connect-provider"><a class="header" href="#configuring-synapse-to-authenticate-against-an-openid-connect-provider">Configuring Synapse to authenticate against an OpenID Connect provider</a></h1>
|
|||
|
<p>Synapse can be configured to use an OpenID Connect Provider (OP) for
|
|||
|
authentication, instead of its own local password database.</p>
|
|||
|
<p>Any OP should work with Synapse, as long as it supports the authorization code
|
|||
|
flow. There are a few options for that:</p>
|
|||
|
<ul>
|
|||
|
<li>
|
|||
|
<p>start a local OP. Synapse has been tested with <a href="https://www.ory.sh/docs/hydra/">Hydra</a> and
|
|||
|
<a href="https://github.com/dexidp/dex">Dex</a>. 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 <code>SSL_CERT_FILE</code>
|
|||
|
environment variable set to the path of the CA.</p>
|
|||
|
</li>
|
|||
|
<li>
|
|||
|
<p>set up a SaaS OP, like <a href="https://developers.google.com/identity/protocols/oauth2/openid-connect">Google</a>, <a href="https://auth0.com/">Auth0</a> or
|
|||
|
<a href="https://www.okta.com/">Okta</a>. Synapse has been tested with Auth0 and Google.</p>
|
|||
|
</li>
|
|||
|
</ul>
|
|||
|
<p>It may also be possible to use other OAuth2 providers which provide the
|
|||
|
<a href="https://tools.ietf.org/html/rfc6749#section-4.1">authorization code grant type</a>,
|
|||
|
such as <a href="https://developer.github.com/apps/building-oauth-apps/authorizing-oauth-apps">Github</a>.</p>
|
|||
|
<h2 id="preparing-synapse"><a class="header" href="#preparing-synapse">Preparing Synapse</a></h2>
|
|||
|
<p>The OpenID integration in Synapse uses the
|
|||
|
<a href="https://pypi.org/project/Authlib/"><code>authlib</code></a> library, which must be installed
|
|||
|
as follows:</p>
|
|||
|
<ul>
|
|||
|
<li>
|
|||
|
<p>The relevant libraries are included in the Docker images and Debian packages
|
|||
|
provided by <code>matrix.org</code> so no further action is needed.</p>
|
|||
|
</li>
|
|||
|
<li>
|
|||
|
<p>If you installed Synapse into a virtualenv, run <code>/path/to/env/bin/pip install matrix-synapse[oidc]</code> to install the necessary dependencies.</p>
|
|||
|
</li>
|
|||
|
<li>
|
|||
|
<p>For other installation mechanisms, see the documentation provided by the
|
|||
|
maintainer.</p>
|
|||
|
</li>
|
|||
|
</ul>
|
|||
|
<p>To enable the OpenID integration, you should then add a section to the <code>oidc_providers</code>
|
|||
|
setting in your configuration file (or uncomment one of the existing examples).
|
|||
|
See <a href="./sample_config.yaml">sample_config.yaml</a> for some sample settings, as well as
|
|||
|
the text below for example configurations for specific providers.</p>
|
|||
|
<h2 id="sample-configs"><a class="header" href="#sample-configs">Sample configs</a></h2>
|

|
<p>Here are a few configs for providers that should work with Synapse.</p>

<p>Azure AD can act as an OpenID Connect Provider. Register a new application under

application should point to your matrix server:
|

|
<code>[synapse public baseurl]/_synapse/client/oidc/callback</code></p>

|
<p>Go to <em>Certificates & secrets</em> and register a new client secret. Make note of your
|

|
Directory (tenant) ID as it will be used in the Azure links.
|

Edit your Synapse config file and change the <code>oidc_config</code> section:</p>

<div id="chapter_begin" style="break-before: page; page-break-before: always;"></div><h1 id="sso-mapping-providers"><a class="header" href="#sso-mapping-providers">SSO Mapping Providers</a></h1>
|
|||
|
<p>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.</p>
|
|||
|
<p>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 <code>John Smith</code>, or <code>Smith, John [Example.com]</code> or any number of
|
|||
|
variations. As each Synapse configuration may want something different, this is
|
|||
|
where SAML mapping providers come into play.</p>
|
|||
|
<p>SSO mapping providers are currently supported for OpenID and SAML SSO
|
|||
|
configurations. Please see the details below for how to implement your own.</p>
|
|||
|
<p>It is up to the mapping provider whether the user should be assigned a predefined
|
|||
|
Matrix ID based on the SSO attributes, or if the user should be allowed to
|
|||
|
choose their own username.</p>
|
|||
|
<p>In the first case - where users are automatically allocated a Matrix ID - it is
|
|||
|
the responsibility of the mapping provider to normalise the SSO attributes and
|
|||
|
map them to a valid Matrix ID. The <a href="https://matrix.org/docs/spec/appendices#user-identifiers">specification for Matrix
|
|||
|
IDs</a> has some
|
|||
|
information about what is considered valid.</p>
|
|||
|
<p>If the mapping provider does not assign a Matrix ID, then Synapse will
|
|||
|
automatically serve an HTML page allowing the user to pick their own username.</p>
|
|||
|
<p>External mapping providers are provided to Synapse in the form of an external
|
|||
|
Python module. You can retrieve this module from <a href="https://pypi.org">PyPI</a> 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).</p>
|
|||
|
<h2 id="openid-mapping-providers"><a class="header" href="#openid-mapping-providers">OpenID Mapping Providers</a></h2>
|
|||
|
<p>The OpenID mapping provider can be customized by editing the
|
|||
|
<code>oidc_config.user_mapping_provider.module</code> config option.</p>
|
|||
|
<p><code>oidc_config.user_mapping_provider.config</code> 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.</p>

|||
|
<ul>
|
|||
|
<li>Arguments:
|
|||
|
<ul>
|
|||
|
<li><code>parsed_config</code> - A configuration object that is the return value of the
|
|||
|
<code>parse_config</code> method. You should set any configuration options needed by
|
|||
|
the module here.</li>
|
|||
|
</ul>
|
|||
|
</li>
|
|||
|
</ul>
|
|||
|
</li>
|
|||
|
<li><code>parse_config(config)</code>
|
|||
|
<ul>
|
|||
|
<li>This method should have the <code>@staticmethod</code> decoration.</li>
|
|||
|
<li>Arguments:
|
|||
|
<ul>
|
|||
|
<li><code>config</code> - A <code>dict</code> representing the parsed content of the
|
|||
|
<code>oidc_config.user_mapping_provider.config</code> homeserver config option.
|
|||
|
Runs on homeserver startup. Providers should extract and validate
|
|||
|
any option values they need here.</li>
|
|||
|
</ul>
|
|||
|
</li>
|
|||
|
<li>Whatever is returned will be passed back to the user mapping provider module's
|
|||
|
<code>__init__</code> method during construction.</li>
|
|||
|
</ul>
|
|||
|
</li>
|
|||
|
<li><code>get_remote_user_id(self, userinfo)</code>
|
|||
|
<ul>
|
|||
|
<li>Arguments:
|
|||
|
<ul>
|
|||
|
<li><code>userinfo</code> - A <code>authlib.oidc.core.claims.UserInfo</code> object to extract user
|
|||
|
information from.</li>
|
|||
|
</ul>
|
|||
|
</li>
|
|||
|
<li>This method must return a string, which is the unique, immutable identifier
|
|||
|
for the user. Commonly the <code>sub</code> claim of the response.</li>
|
|||
|
</ul>
|
|||
|
</li>
|

|
<li><code>map_user_attributes(self, userinfo, token, failures)</code>
|
|||
|
<ul>
|
|||
|
<li>This method must be async.</li>
|
|||
|
<li>Arguments:
|
|||
|
<ul>
|

|
<li><code>userinfo</code> - A <code>authlib.oidc.core.claims.UserInfo</code> object to extract user
|
|||
|
information from.</li>
|
|||
|
<li><code>token</code> - A dictionary which includes information necessary to make
|
|||
|
further requests to the OpenID provider.</li>
|
|||
|
<li><code>failures</code> - An <code>int</code> 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
|
|||
|
<code>john.doe</code> as the value of <code>localpart</code> 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
|
|||
|
<code>localpart</code> value, such as <code>john.doe1</code>.</li>
|
|||
|
</ul>
|
|||
|
</li>
|
|||
|
<li>Returns a dictionary with two keys:
|

|
<ul>
|
|||
|
<li><code>localpart</code>: A string, used to generate the Matrix ID. If this is
|
|||
|
<code>None</code>, the user is prompted to pick their own username. This is only used
|

|
during a user's first login. Once a localpart has been associated with a

|
<p>The SAML mapping provider can be customized by editing the
|
|||
|
<code>saml2_config.user_mapping_provider.module</code> config option.</p>
|
|||
|
<p><code>saml2_config.user_mapping_provider.config</code> 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.</p>

|
<p>A custom mapping provider must specify the following methods:</p>
|
|||
|
<ul>
|
|||
|
<li><code>__init__(self, parsed_config, module_api)</code>
|
|||
|
<ul>
|
|||
|
<li>Arguments:
|
|||
|
<ul>
|
|||
|
<li><code>parsed_config</code> - A configuration object that is the return value of the
|
|||
|
<code>parse_config</code> method. You should set any configuration options needed by
|
|||
|
the module here.</li>
|
|||
|
<li><code>module_api</code> - a <code>synapse.module_api.ModuleApi</code> object which provides the
|

<li>This method should have the <code>@staticmethod</code> decoration.</li>
|
|||
|
<li>Arguments:
|
|||
|
<ul>
|
|||
|
<li><code>config</code> - A <code>dict</code> representing the parsed content of the
|
|||
|
<code>saml_config.user_mapping_provider.config</code> homeserver config option.
|
|||
|
Runs on homeserver startup. Providers should extract and validate
|
|||
|
any option values they need here.</li>
|
|||
|
</ul>
|
|||
|
</li>
|
|||
|
<li>Whatever is returned will be passed back to the user mapping provider module's
|

|
<code>__init__</code> method during construction.</li>
|
|||
|
</ul>
|
|||
|
</li>
|
|||
|
<li><code>get_saml_attributes(config)</code>
|
|||
|
<ul>
|

|
<li>This method should have the <code>@staticmethod</code> decoration.</li>
|
|||
|
<li>Arguments:
|
|||
|
<ul>
|
|||
|
<li><code>config</code> - A object resulting from a call to <code>parse_config</code>.</li>
|
|||
|
</ul>
|
|||
|
</li>
|
|||
|
<li>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.</li>
|
|||
|
</ul>
|
|||
|
</li>
|
|||
|
<li><code>get_remote_user_id(self, saml_response, client_redirect_url)</code>
|
|||
|
<ul>
|
|||
|
<li>Arguments:
|
|||
|
<ul>
|
|||
|
<li><code>saml_response</code> - A <code>saml2.response.AuthnResponse</code> object to extract user
|
|||
|
information from.</li>
|
|||
|
<li><code>client_redirect_url</code> - A string, the URL that the client will be
|
|||
|
redirected to.</li>
|
|||
|
</ul>
|
|||
|
</li>
|
|||
|
<li>This method must return a string, which is the unique, immutable identifier
|
|||
|
for the user. Commonly the <code>uid</code> claim of the response.</li>
|
|||
|
</ul>
|
|||
|
</li>
|
|||
|
<li><code>saml_response_to_user_attributes(self, saml_response, failures, client_redirect_url)</code>
|
|||
|
<ul>
|
|||
|
<li>
|
|||
|
<p>Arguments:</p>
|
|||
|
<ul>
|
|||
|
<li><code>saml_response</code> - A <code>saml2.response.AuthnResponse</code> object to extract user
|
|||
|
information from.</li>
|
|||
|
<li><code>failures</code> - An <code>int</code> 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
|
|||
|
<code>john.doe</code> as the value of <code>mxid_localpart</code> 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
|
|||
|
<code>mxid_localpart</code> value, such as <code>john.doe1</code>.</li>
|
|||
|
<li><code>client_redirect_url</code> - A string, the URL that the client will be
|
|||
|
redirected to.</li>
|
|||
|
</ul>
|
|||
|
</li>
|
|||
|
<li>
|
|||
|
<p>This method must return a dictionary, which will then be used by Synapse
|
|||
|
to build a new user. The following keys are allowed:</p>
|
|||
|
<ul>
|
|||
|
<li><code>mxid_localpart</code> - A string, the mxid localpart of the new user. If this is
|
|||
|
<code>None</code>, the user is prompted to pick their own username. This is only used
|
|||
|
during a user's first login. Once a localpart has been associated with a
|
|||
|
remote user ID (see <code>get_remote_user_id</code>) it cannot be updated.</li>
|
|||
|
<li><code>displayname</code> - The displayname of the new user. If not provided, will default to
|
|||
|
the value of <code>mxid_localpart</code>.</li>
|
|||
|
<li><code>emails</code> - A list of emails for the new user. If not provided, will
|
|||
|
default to an empty list.</li>
|
|||
|
</ul>
|
|||
|
<p>Alternatively it can raise a <code>synapse.api.errors.RedirectException</code> to
|
|||
|
redirect the user to another page. This is useful to prompt the user for
|
|||
|
additional information, e.g. if you want them to provide their own username.
|
|||
|
It is the responsibility of the mapping provider to either redirect back
|
|||
|
to <code>client_redirect_url</code> (including any additional information) or to
|
|||
|
complete registration using methods from the <code>ModuleApi</code>.</p>

|
|||
|
<p>Password auth providers offer a way for server administrators to
|
|||
|
integrate their Synapse installation with an existing authentication
|
|||
|
system.</p>
|
|||
|
<p>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.</p>
|
|||
|
<p>This document serves as a reference for those looking to implement their
|
|||
|
own password auth providers. Additionally, here is a list of known
|
|||
|
password auth provider module implementations:</p>

</ul>
|
|||
|
<h2 id="required-methods"><a class="header" href="#required-methods">Required methods</a></h2>
|
|||
|
<p>Password auth provider classes must provide the following methods:</p>
|
|||
|
<ul>
|
|||
|
<li>
|
|||
|
<p><code>parse_config(config)</code>
|
|||
|
This method is passed the <code>config</code> object for this module from the
|
|||
|
homeserver configuration file.</p>
|
|||
|
<p>It should perform any appropriate sanity checks on the provided
|
|||
|
configuration, and return an object which is then passed into
|
|||
|
<code>__init__</code>.</p>
|
|||
|
<p>This method should have the <code>@staticmethod</code> decoration.</p>
|
|||
|
</li>
|
|||
|
<li>
|
|||
|
<p><code>__init__(self, config, account_handler)</code></p>
|
|||
|
<p>The constructor is passed the config object returned by
|
|||
|
<code>parse_config</code>, and a <code>synapse.module_api.ModuleApi</code> object which
|
|||
|
allows the password provider to check if accounts exist and/or create
|
|||
|
new ones.</p>
|
|||
|
</li>
|
|||
|
</ul>
|
|||
|
<h2 id="optional-methods"><a class="header" href="#optional-methods">Optional methods</a></h2>
|
|||
|
<p>Password auth provider classes may optionally provide the following methods:</p>
|
|||
|
<ul>
|
|||
|
<li>
|
|||
|
<p><code>get_db_schema_files(self)</code></p>
|
|||
|
<p>This method, if implemented, should return an Iterable of
|
|||
|
<code>(name, stream)</code> 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.</p>
|
|||
|
</li>
|
|||
|
<li>
|
|||
|
<p><code>get_supported_login_types(self)</code></p>
|
|||
|
<p>This method, if implemented, should return a <code>dict</code> mapping from a
|
|||
|
login type identifier (such as <code>m.login.password</code>) to an iterable
|
|||
|
giving the fields which must be provided by the user in the submission
|
|||
|
to <a href="https://matrix.org/docs/spec/client_server/latest#post-matrix-client-r0-login">the <code>/login</code> API</a>.
|
|||
|
These fields are passed in the <code>login_dict</code> dictionary to <code>check_auth</code>.</p>
|
|||
|
<p>For example, if a password auth provider wants to implement a custom
|
|||
|
login type of <code>com.example.custom_login</code>, where the client is expected
|
|||
|
to pass the fields <code>secret1</code> and <code>secret2</code>, the provider should
|
|||
|
implement this method and return the following dict:</p>
|
|||
|
<pre><code class="language-python">{"com.example.custom_login": ("secret1", "secret2")}
|
|||
|
</code></pre>
|
|||
|
</li>
|
|||
|
<li>
|
|||
|
<p><code>check_auth(self, username, login_type, login_dict)</code></p>
|
|||
|
<p>This method 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 <code>get_supported_login_types</code>.</p>
|
|||
|
<p>It is passed the (possibly unqualified) <code>user</code> field provided by the client,
|
|||
|
the login type, and a dictionary of login secrets passed by the
|
|||
|
client.</p>
|
|||
|
<p>The method should return an <code>Awaitable</code> object, which resolves
|
|||
|
to the canonical <code>@localpart:domain</code> user ID if authentication is
|
|||
|
successful, and <code>None</code> if not.</p>
|
|||
|
<p>Alternatively, the <code>Awaitable</code> can resolve to a <code>(str, func)</code> tuple, in
|
|||
|
which case the second field is a callback which will be called with
|
|||
|
the result from the <code>/login</code> call (including <code>access_token</code>,
|
|||
|
<code>device_id</code>, etc.)</p>
|
|||
|
</li>
|
|||
|
<li>
|
|||
|
<p><code>check_3pid_auth(self, medium, address, password)</code></p>
|
|||
|
<p>This method, if implemented, is called when a user attempts to
|
|||
|
register or log in with a third party identifier, such as email. It is
|
|||
|
passed the medium (ex. "email"), an address (ex.
|
|||
|
"<a href="mailto:jdoe@example.com">jdoe@example.com</a>") and the user's password.</p>
|
|||
|
<p>The method should return an <code>Awaitable</code> object, which resolves
|
|||
|
to a <code>str</code> containing the user's (canonical) User id if
|
|||
|
authentication was successful, and <code>None</code> if not.</p>
|
|||
|
<p>As with <code>check_auth</code>, the <code>Awaitable</code> may alternatively resolve to a
|
|||
|
<code>(user_id, callback)</code> tuple.</p>
|
|||
|
</li>
|
|||
|
<li>
|
|||
|
<p><code>check_password(self, user_id, password)</code></p>
|
|||
|
<p>This method provides a simpler interface than
|
|||
|
<code>get_supported_login_types</code> and <code>check_auth</code> for password auth
|
|||
|
providers that just want to provide a mechanism for validating
|
|||
|
<code>m.login.password</code> logins.</p>
|
|||
|
<p>If implemented, it will be called to check logins with an
|
|||
|
<code>m.login.password</code> login type. It is passed a qualified
|
|||
|
<code>@localpart:domain</code> user id, and the password provided by the user.</p>
|
|||
|
<p>The method should return an <code>Awaitable</code> object, which resolves
|
|||
|
to <code>True</code> if authentication is successful, and <code>False</code> if not.</p>
|
|||
|
</li>
|
|||
|
<li>
|
|||
|
<p><code>on_logged_out(self, user_id, device_id, access_token)</code></p>
|
|||
|
<p>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.</p>
|
|||
|
<p>It may return an <code>Awaitable</code> object; the logout request will
|
|||
|
wait for the <code>Awaitable</code> to complete, but the result is ignored.</p>
|
|||
|
</li>
|

|
|||
|
<p>Synapse comes with a non-standard login type to support
|
|||
|
<a href="https://en.wikipedia.org/wiki/JSON_Web_Token">JSON Web Tokens</a>. In general the
|
|||
|
documentation for
|
|||
|
<a href="https://matrix.org/docs/spec/client_server/r0.6.1#login">the login endpoint</a>
|
|||
|
is still valid (and the mechanism works similarly to the
|
|||
|
<a href="https://matrix.org/docs/spec/client_server/r0.6.1#token-based">token based login</a>).</p>
|
|||
|
<p>To log in using a JSON Web Token, clients should submit a <code>/login</code> request as
|
|||
|
follows:</p>
|
|||
|
<pre><code class="language-json">{
|
|||
|
"type": "org.matrix.login.jwt",
|
|||
|
"token": "<jwt>"
|
|||
|
}
|
|||
|
</code></pre>
|
|||
|
<p>Note that the login type of <code>m.login.jwt</code> is supported, but is deprecated. This
|
|||
|
will be removed in a future version of Synapse.</p>
|
|||
|
<p>The <code>token</code> field should include the JSON web token with the following claims:</p>
|
|||
|
<ul>
|
|||
|
<li>The <code>sub</code> (subject) claim is required and should encode the local part of the
|
|||
|
user ID.</li>
|
|||
|
<li>The expiration time (<code>exp</code>), not before time (<code>nbf</code>), and issued at (<code>iat</code>)
|
|||
|
claims are optional, but validated if present.</li>
|
|||
|
<li>The issuer (<code>iss</code>) claim is optional, but required and validated if configured.</li>
|
|||
|
<li>The audience (<code>aud</code>) claim is optional, but required and validated if configured.
|
|||
|
Providing the audience claim when not configured will cause validation to fail.</li>
|
|||
|
</ul>
|
|||
|
<p>In the case that the token is not valid, the homeserver must respond with
|
|||
|
<code>403 Forbidden</code> and an error code of <code>M_FORBIDDEN</code>.</p>
|
|||
|
<p>As with other login types, there are additional fields (e.g. <code>device_id</code> and
|
|||
|
<code>initial_device_display_name</code>) which can be included in the above request.</p>
|
|||
|
<h2 id="preparing-synapse-1"><a class="header" href="#preparing-synapse-1">Preparing Synapse</a></h2>
|
|||
|
<p>The JSON Web Token integration in Synapse uses the
|
|||
|
<a href="https://pypi.org/project/pyjwt/"><code>PyJWT</code></a> library, which must be installed
|
|||
|
as follows:</p>
|
|||
|
<ul>
|
|||
|
<li>
|
|||
|
<p>The relevant libraries are included in the Docker images and Debian packages
|
|||
|
provided by <code>matrix.org</code> so no further action is needed.</p>
|
|||
|
</li>
|
|||
|
<li>
|
|||
|
<p>If you installed Synapse into a virtualenv, run <code>/path/to/env/bin/pip install synapse[pyjwt]</code> to install the necessary dependencies.</p>
|
|||
|
</li>
|
|||
|
<li>
|
|||
|
<p>For other installation mechanisms, see the documentation provided by the
|
|||
|
maintainer.</p>
|
|||
|
</li>
|
|||
|
</ul>
|
|||
|
<p>To enable the JSON web token integration, you should then add an <code>jwt_config</code> section
|
|||
|
to your configuration file (or uncomment the <code>enabled: true</code> line in the
|
|||
|
existing section). See <a href="./sample_config.yaml">sample_config.yaml</a> for some

|
|||
|
<p>'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.</p>
|
|||
|
<p>They are used as part of communication of the server polices (see
|
|||
|
<a href="consent_tracking.html">Consent Tracking</a>), however the intention is that
|
|||
|
they may also find a use for features such as "Message of the day".</p>
|
|||
|
<p>This is a feature specific to Synapse, but it uses standard Matrix
|
|||
|
communication mechanisms, so should work with any Matrix client.</p>
|
|||
|
<h2 id="user-experience"><a class="header" href="#user-experience">User experience</a></h2>
|
|||
|
<p>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
|
|||
|
<code>homeserver.yaml</code>). They will be <strong>unable to reject</strong> this invitation -
|
|||
|
attempts to do so will receive an error.</p>
|
|||
|
<p>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).</p>
|
|||
|
<p>The user is prevented from sending any messages in this room by the power
|
|||
|
levels.</p>
|
|||
|
<p>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.</p>
|
|||
|
<h2 id="synapse-configuration"><a class="header" href="#synapse-configuration">Synapse configuration</a></h2>
|
|||
|
<p>Server notices come from a specific user id on the server. Server
|
|||
|
administrators are free to choose the user id - something like <code>server</code> is
|
|||
|
suggested, meaning the notices will come from
|
|||
|
<code>@server:<your_server_name></code>. Once the Server Notices user is configured, that
|
|||
|
user id becomes a special, privileged user, so administrators should ensure
|
|||
|
that <strong>it is not already allocated</strong>.</p>
|
|||
|
<p>In order to support server notices, it is necessary to add some configuration
|
|||
|
to the <code>homeserver.yaml</code> file. In particular, you should add a <code>server_notices</code>
|
|||
|
section, which should look like this:</p>
|
|||
|
<pre><code class="language-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"
|
|||
|
</code></pre>
|
|||
|
<p>The only compulsory setting is <code>system_mxid_localpart</code>, which defines the user
|
|||
|
id of the Server Notices user, as above. <code>room_name</code> defines the name of the
|
|||
|
room which will be created.</p>
|
|||
|
<p><code>system_mxid_display_name</code> and <code>system_mxid_avatar_url</code> can be used to set the
|
|||
|
displayname and avatar of the Server Notices user.</p>
|
|||
|
<h2 id="sending-notices"><a class="header" href="#sending-notices">Sending notices</a></h2>

|
|||
|
<p>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.</p>
|
|||
|
<p>There are several parts to this functionality; each requires some specific
|
|||
|
configuration in <code>homeserver.yaml</code> to be enabled.</p>
|
|||
|
<p>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.</p>
|
|||
|
<h2 id="collecting-policy-agreement-from-a-user"><a class="header" href="#collecting-policy-agreement-from-a-user">Collecting policy agreement from a user</a></h2>
|
|||
|
<p>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.</p>
|
|||
|
<p>To enable this, first create templates for the policy and success pages.
|
|||
|
These should be stored on the local filesystem.</p>
|
|||
|
<p>These templates use the <a href="http://jinja.pocoo.org">Jinja2</a> templating language,
|
|||
|
and <a href="https://github.com/matrix-org/synapse/tree/develop/docs/privacy_policy_templates/">docs/privacy_policy_templates</a>
|
|||
|
gives examples of the sort of thing that can be done.</p>
|
|||
|
<p>Note that the templates must be stored under a name giving the language of the
|
|||
|
template - currently this must always be <code>en</code> (for "English");
|
|||
|
internationalisation support is intended for the future.</p>
|
|||
|
<p>The template for the policy itself should be versioned and named according to
|
|||
|
the version: for example <code>1.0.html</code>. The version of the policy which the user
|
|||
|
has agreed to is stored in the database.</p>
|
|||
|
<p>Once the templates are in place, make the following changes to <code>homeserver.yaml</code>:</p>
|
|||
|
<ol>
|
|||
|
<li>
|
|||
|
<p>Add a <code>user_consent</code> section, which should look like:</p>
|
|||
|
<pre><code class="language-yaml">user_consent:
|
|||
|
template_dir: privacy_policy_templates
|
|||
|
version: 1.0
|
|||
|
</code></pre>
|
|||
|
<p><code>template_dir</code> points to the directory containing the policy
|
|||
|
templates. <code>version</code> defines the version of the policy which will be served
|
|||
|
to the user. In the example above, Synapse will serve
|
|||
|
<code>privacy_policy_templates/en/1.0.html</code>.</p>
|
|||
|
</li>
|
|||
|
<li>
|
|||
|
<p>Add a <code>form_secret</code> setting at the top level:</p>
|
|||
|
<pre><code class="language-yaml">form_secret: "<unique secret>"
|
|||
|
</code></pre>
|
|||
|
<p>This should be set to an arbitrary secret string (try <code>pwgen -y 30</code> to
|
|||
|
generate suitable secrets).</p>
|
|||
|
<p>More on what this is used for below.</p>
|
|||
|
</li>
|
|||
|
<li>
|
|||
|
<p>Add <code>consent</code> wherever the <code>client</code> resource is currently enabled in the
|
|||
|
<code>listeners</code> configuration. For example:</p>
|
|||
|
<pre><code class="language-yaml">listeners:
|
|||
|
- port: 8008
|
|||
|
resources:
|
|||
|
- names:
|
|||
|
- client
|
|||
|
- consent
|
|||
|
</code></pre>
|
|||
|
</li>
|
|||
|
</ol>
|
|||
|
<p>Finally, ensure that <code>jinja2</code> is installed. If you are using a virtualenv, this
|
|||
|
should be a matter of <code>pip install Jinja2</code>. On debian, try <code>apt-get install python-jinja2</code>.</p>
|
|||
|
<p>Once this is complete, and the server has been restarted, try visiting
|
|||
|
<code>https://<server>/_matrix/consent</code>. 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.</p>

|

|
<ol>
|

|
<li>
|

|
<p>Add the following to your configuration:</p>
|
|||
|
<pre><code class="language-yaml">user_consent:
|

require_at_registration: true

|
</code></pre>
|
|||
|
</li>
|
|||
|
<li>
|
|||
|
<p>In your consent templates, make use of the <code>public_version</code> variable to
|
|||
|
see if an unauthenticated user is viewing the page. This is typically
|
|||
|
wrapped around the form that would be used to actually agree to the document:</p>
|
|||
|
<pre><code>{% if not public_version %}
|
|||
|
<!-- The variables used here are only provided when the 'u' param is given to the homeserver -->
|
|||
|
<form method="post" action="consent">
|
|||
|
<input type="hidden" name="v" value="{{version}}"/>
|
|||
|
<input type="hidden" name="u" value="{{user}}"/>
|
|||
|
<input type="hidden" name="h" value="{{userhmac}}"/>
|
|||
|
<input type="submit" value="Sure thing!"/>
|
|||
|
</form>
|
|||
|
{% endif %}
|
|||
|
</code></pre>
|
|||
|
</li>
|
|||
|
<li>
|
|||
|
<p>Restart Synapse to apply the changes.</p>
|
|||
|
</li>
|
|||
|
</ol>
|
|||
|
<p>Visiting <code>https://<server>/_matrix/consent</code> should now give you a view of the privacy
|
|||
|
document. This is what users will be able to see when registering for accounts.</p>
|
|||
|
<h3 id="constructing-the-consent-uri"><a class="header" href="#constructing-the-consent-uri">Constructing the consent URI</a></h3>
|
|||
|
<p>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 <code>https://<server>/_matrix/consent</code> URL and add the following
|
|||
|
query parameters:</p>
|
|||
|
<ul>
|
|||
|
<li>
|
|||
|
<p><code>u</code>: the user id of the user. This can either be a full MXID
|
|||
|
(<code>@user:server.com</code>) or just the localpart (<code>user</code>).</p>
|
|||
|
</li>
|
|||
|
<li>
|
|||
|
<p><code>h</code>: hex-encoded HMAC-SHA256 of <code>u</code> using the <code>form_secret</code> as a key. It is
|
|||
|
possible to calculate this on the commandline with something like:</p>
|
|||
|
<pre><code class="language-bash">echo -n '<user>' | openssl sha256 -hmac '<form_secret>'
|
|||
|
</code></pre>
|
|||
|
<p>This should result in a URI which looks something like:
|
|||
|
<code>https://<server>/_matrix/consent?u=<user>&h=68a152465a4d...</code>.</p>
|
|||
|
</li>
|
|||
|
</ul>
|
|||
|
<p>Note that not providing a <code>u</code> parameter will be interpreted as wanting to view
|
|||
|
the document from an unauthenticated perspective, such as prior to registration.
|
|||
|
Therefore, the <code>h</code> parameter is not required in this scenario. To enable this
|
|||
|
behaviour, set <code>require_at_registration</code> to <code>true</code> in your <code>user_consent</code> config.</p>

|||

|||
|
version of the policy. To do so:</p>
|
|||
|
<ul>
|
|||
|
<li>
|

|
<p>ensure that the consent resource is configured, as in the previous section</p>

</li>
|
|||
|
<li>
|

|
<p>ensure that server notices are configured, as in <a href="server_notices.html">the server notice documentation</a>.</p>
|
|||
|
</li>
|
|||
|
<li>
|
|||
|
<p>Add <code>server_notice_content</code> under <code>user_consent</code> in <code>homeserver.yaml</code>. For
|
|||
|
example:</p>
|
|||
|
<pre><code class="language-yaml">user_consent:

|
Please give your consent to the privacy policy at %(consent_uri)s.
|

|
</code></pre>
|
|||
|
<p>Synapse automatically replaces the placeholder <code>%(consent_uri)s</code> with the
|
|||
|
consent uri for that user.</p>
|
|||
|
</li>
|
|||
|
<li>
|
|||
|
<p>ensure that <code>public_baseurl</code> is set in <code>homeserver.yaml</code>, and gives the base
|

<code>consent_uri</code> in the server notice.)</p>

<p>Synapse can be configured to block any attempts to join rooms or send messages

<p>The <code>GET /_matrix/media/r0/preview_url</code> endpoint provides a generic preview API
|
|||
|
for URLs which outputs <a href="https://ogp.me/">Open Graph</a> responses (with some Matrix
|
|||
|
specific additions).</p>
|
|||
|
<p>This does have trade-offs compared to other designs:</p>
|
|||
|
<ul>
|
|||
|
<li>Pros:
|
|||
|
<ul>
|
|||
|
<li>Simple and flexible; can be used by any clients at any point</li>
|
|||
|
</ul>
|
|||
|
</li>
|
|||
|
<li>Cons:
|
|||
|
<ul>
|
|||
|
<li>If each homeserver provides one of these independently, all the HSes in a
|
|||
|
room may needlessly DoS the target URI</li>
|
|||
|
<li>The URL metadata must be stored somewhere, rather than just using Matrix

itself to store the media.</li>
|

<li>Matrix cannot be used to distribute the metadata between homeservers.</li>
|

|
</ul>
|

|
</li>
|
|||
|
</ul>
|
|||
|
<p>When Synapse is asked to preview a URL it does the following:</p>
|
|||
|
<ol>
|
|||
|
<li>Checks against a URL blacklist (defined as <code>url_preview_url_blacklist</code> in the
|
|||
|
config).</li>
|
|||
|
<li>Checks the in-memory cache by URLs and returns the result if it exists. (This
|
|||
|
is also used to de-duplicate processing of multiple in-flight requests at once.)</li>
|
|||
|
<li>Kicks off a background process to generate a preview:
|
|||
|
<ol>
|
|||
|
<li>Checks the database cache by URL and timestamp and returns the result if it
|
|||
|
has not expired and was successful (a 2xx return code).</li>
|
|||
|
<li>Checks if the URL matches an oEmbed pattern. If it does, fetch the oEmbed
|
|||
|
response. If this is an image, replace the URL to fetch and continue. If
|
|||
|
if it is HTML content, use the HTML as the document and continue.</li>
|
|||
|
<li>If it doesn't match an oEmbed pattern, downloads the URL and stores it
|
|||
|
into a file via the media storage provider and saves the local media
|
|||

metadata.</li>

<p>The user directory is currently maintained based on the 'visible' users
|

on this particular server - i.e. ones which your account shares a room with, or
|
|||
|
who are present in a publicly viewable room present on the server.</p>
|
|||
|
<p>The directory info is stored in various tables, which can (typically after
|
|||
|
DB corruption) get stale or out of sync. If this happens, for now the
|
|||
|
solution to fix it is to execute the SQL <a href="https://github.com/matrix-org/synapse/blob/master/synapse/storage/schema/main/delta/53/user_dir_populate.sql">here</a>
|
|||
|
and then restart synapse. This should then start a background task to

|
flush the current tables and regenerate the directory.</p>
|
|||
|
<h2 id="data-model"><a class="header" href="#data-model">Data model</a></h2>
|

|
<p>There are five relevant tables that collectively form the "user directory".

Three of them track a master list of all the users we could search for.

The last two (collectively called the "search tables") track who can

see who.</p>
|

<p>From all of these tables we exclude three types of local user:</p>

|
<ul>
|

<li>Because there's only one directory entry per user, it's important that we only

<div id="chapter_begin" style="break-before: page; page-break-before: always;"></div><h1 id="message-retention-policies"><a class="header" href="#message-retention-policies">Message retention policies</a></h1>
|
|||
|
<p>Synapse admins can enable support for message retention policies on
|
|||
|
their homeserver. Message retention policies exist at a room level,
|
|||
|
follow the semantics described in
|
|||
|
<a href="https://github.com/matrix-org/matrix-doc/blob/matthew/msc1763/proposals/1763-configurable-retention-periods.md">MSC1763</a>,
|
|||
|
and allow server and room admins to configure how long messages should
|
|||
|
be kept in a homeserver's database before being purged from it.
|
|||
|
<strong>Please note that, as this feature isn't part of the Matrix
|
|||
|
specification yet, this implementation is to be considered as
|
|||
|
experimental.</strong> </p>
|
|||
|
<p>A message retention policy is mainly defined by its <code>max_lifetime</code>
|
|||
|
parameter, which defines how long a message can be kept around after
|
|||
|
it was sent to the room. If a room doesn't have a message retention
|
|||
|
policy, and there's no default one for a given server, then no message
|
|||
|
sent in that room is ever purged on that server.</p>
|
|||
|
<p>MSC1763 also specifies semantics for a <code>min_lifetime</code> parameter which
|
|||
|
defines the amount of time after which an event <em>can</em> get purged (after
|
|||
|
it was sent to the room), but Synapse doesn't currently support it
|
|||
|
beyond registering it.</p>
|
|||
|
<p>Both <code>max_lifetime</code> and <code>min_lifetime</code> are optional parameters.</p>
|
|||
|
<p>Note that message retention policies don't apply to state events.</p>
|
|||
|
<p>Once an event reaches its expiry date (defined as the time it was sent
|
|||
|
plus the value for <code>max_lifetime</code> in the room), two things happen:</p>
|
|||
|
<ul>
|
|||
|
<li>Synapse stops serving the event to clients via any endpoint.</li>
|
|||
|
<li>The message gets picked up by the next purge job (see the "Purge jobs"
|
|||
|
section) and is removed from Synapse's database.</li>
|
|||
|
</ul>
|
|||
|
<p>Since purge jobs don't run continuously, this means that an event might
|
|||
|
stay in a server's database for longer than the value for <code>max_lifetime</code>
|
|||
|
in the room would allow, though hidden from clients.</p>
|
|||
|
<p>Similarly, if a server (with support for message retention policies
|
|||
|
enabled) receives from another server an event that should have been
|
|||
|
purged according to its room's policy, then the receiving server will
|
|||
|
process and store that event until it's picked up by the next purge job,
|
|||
|
though it will always hide it from clients.</p>
|
|||
|
<p>Synapse requires at least one message in each room, so it will never
|
|||
|
delete the last message in a room. It will, however, hide it from
|
|||
|
clients.</p>
|
|||
|
<h2 id="server-configuration"><a class="header" href="#server-configuration">Server configuration</a></h2>
|
|||
|
<p>Support for this feature can be enabled and configured in the
|
|||
|
<code>retention</code> section of the Synapse configuration file (see the
|
|||
|
<a href="https://github.com/matrix-org/synapse/blob/v1.36.0/docs/sample_config.yaml#L451-L518">sample file</a>).</p>
|
|||
|
<p>To enable support for message retention policies, set the setting
|
|||
|
<code>enabled</code> in this section to <code>true</code>.</p>
|
|||
|
<h3 id="default-policy"><a class="header" href="#default-policy">Default policy</a></h3>
|
|||
|
<p>A default message retention policy is a policy defined in Synapse's
|
|||
|
configuration that is used by Synapse for every room that doesn't have a
|
|||
|
message retention policy configured in its state. This allows server
|
|||
|
admins to ensure that messages are never kept indefinitely in a server's
|
|||
|
database. </p>
|
|||
|
<p>A default policy can be defined as such, in the <code>retention</code> section of
|
|||
|
the configuration file:</p>
|
|||
|
<pre><code class="language-yaml"> default_policy:
|
|||
|
min_lifetime: 1d
|
|||
|
max_lifetime: 1y
|
|||
|
</code></pre>
|
|||
|
<p>Here, <code>min_lifetime</code> and <code>max_lifetime</code> have the same meaning and level
|
|||
|
of support as previously described. They can be expressed either as a
|
|||
|
duration (using the units <code>s</code> (seconds), <code>m</code> (minutes), <code>h</code> (hours),
|
|||
|
<code>d</code> (days), <code>w</code> (weeks) and <code>y</code> (years)) or as a number of milliseconds.</p>
|
|||
|
<h3 id="purge-jobs"><a class="header" href="#purge-jobs">Purge jobs</a></h3>
|
|||
|
<p>Purge jobs are the jobs that Synapse runs in the background to purge
|
|||
|
expired events from the database. They are only run if support for
|
|||
|
message retention policies is enabled in the server's configuration. If
|
|||
|
no configuration for purge jobs is configured by the server admin,
|
|||
|
Synapse will use a default configuration, which is described in the
|
|||
|
<a href="https://github.com/matrix-org/synapse/blob/v1.36.0/docs/sample_config.yaml#L451-L518">sample configuration file</a>.</p>
|
|||
|
<p>Some server admins might want a finer control on when events are removed
|
|||
|
depending on an event's room's policy. This can be done by setting the
|
|||
|
<code>purge_jobs</code> sub-section in the <code>retention</code> section of the configuration
|
|||
|
file. An example of such configuration could be:</p>
|
|||
|
<pre><code class="language-yaml"> purge_jobs:
|
|||
|
- longest_max_lifetime: 3d
|
|||
|
interval: 12h
|
|||
|
- shortest_max_lifetime: 3d
|
|||
|
longest_max_lifetime: 1w
|
|||
|
interval: 1d
|
|||
|
- shortest_max_lifetime: 1w
|
|||
|
interval: 2d
|
|||
|
</code></pre>
|
|||
|
<p>In this example, we define three jobs:</p>
|
|||
|
<ul>
|
|||
|
<li>one that runs twice a day (every 12 hours) and purges events in rooms
|
|||
|
which policy's <code>max_lifetime</code> is lower or equal to 3 days.</li>
|
|||
|
<li>one that runs once a day and purges events in rooms which policy's
|
|||
|
<code>max_lifetime</code> is between 3 days and a week.</li>
|
|||
|
<li>one that runs once every 2 days and purges events in rooms which
|
|||
|
policy's <code>max_lifetime</code> is greater than a week.</li>
|
|||
|
</ul>
|
|||
|
<p>Note that this example is tailored to show different configurations and
|
|||
|
features slightly more jobs than it's probably necessary (in practice, a
|
|||
|
server admin would probably consider it better to replace the two last
|
|||
|
jobs with one that runs once a day and handles rooms which which
|
|||
|
policy's <code>max_lifetime</code> is greater than 3 days).</p>
|
|||
|
<p>Keep in mind, when configuring these jobs, that a purge job can become
|
|||
|
quite heavy on the server if it targets many rooms, therefore prefer
|
|||
|
having jobs with a low interval that target a limited set of rooms. Also
|
|||
|
make sure to include a job with no minimum and one with no maximum to
|
|||
|
make sure your configuration handles every policy.</p>
|
|||
|
<p>As previously mentioned in this documentation, while a purge job that
|
|||
|
runs e.g. every day means that an expired event might stay in the
|
|||
|
database for up to a day after its expiry, Synapse hides expired events
|
|||
|
from clients as soon as they expire, so the event is not visible to
|
|||
|
local users between its expiry date and the moment it gets purged from
|
|||
|
the server's database.</p>
|
|||
|
<h3 id="lifetime-limits"><a class="header" href="#lifetime-limits">Lifetime limits</a></h3>
|
|||
|
<p>Server admins can set limits on the values of <code>max_lifetime</code> to use when
|
|||
|
purging old events in a room. These limits can be defined as such in the
|
|||
|
<code>retention</code> section of the configuration file:</p>
|
|||
|
<pre><code class="language-yaml"> allowed_lifetime_min: 1d
|
|||
|
allowed_lifetime_max: 1y
|
|||
|
</code></pre>
|
|||
|
<p>The limits are considered when running purge jobs. If necessary, the
|
|||
|
effective value of <code>max_lifetime</code> will be brought between
|
|||
|
<code>allowed_lifetime_min</code> and <code>allowed_lifetime_max</code> (inclusive).
|
|||
|
This means that, if the value of <code>max_lifetime</code> defined in the room's state
|
|||
|
is lower than <code>allowed_lifetime_min</code>, the value of <code>allowed_lifetime_min</code>
|
|||
|
will be used instead. Likewise, if the value of <code>max_lifetime</code> is higher
|
|||
|
than <code>allowed_lifetime_max</code>, the value of <code>allowed_lifetime_max</code> will be
|
|||
|
used instead.</p>
|
|||
|
<p>In the example above, we ensure Synapse never deletes events that are less
|
|||
|
than one day old, and that it always deletes events that are over a year
|
|||
|
old.</p>
|
|||
|
<p>If a default policy is set, and its <code>max_lifetime</code> value is lower than
|
|||
|
<code>allowed_lifetime_min</code> or higher than <code>allowed_lifetime_max</code>, the same
|
|||
|
process applies.</p>
|
|||
|
<p>Both parameters are optional; if one is omitted Synapse won't use it to
|
|||
|
adjust the effective value of <code>max_lifetime</code>.</p>
|
|||
|
<p>Like other settings in this section, these parameters can be expressed
|
|||
|
either as a duration or as a number of milliseconds.</p>
|
|||
|
<h2 id="room-configuration"><a class="header" href="#room-configuration">Room configuration</a></h2>
|
|||
|
<p>To configure a room's message retention policy, a room's admin or
|
|||
|
moderator needs to send a state event in that room with the type
|
|||
|
<code>m.room.retention</code> and the following content:</p>
|
|||
|
<pre><code class="language-json">{
|
|||
|
"max_lifetime": ...
|
|||
|
}
|
|||
|
</code></pre>
|
|||
|
<p>In this event's content, the <code>max_lifetime</code> parameter has the same
|
|||
|
meaning as previously described, and needs to be expressed in
|
|||
|
milliseconds. The event's content can also include a <code>min_lifetime</code>
|
|||
|
parameter, which has the same meaning and limited support as previously
|
|||
|
described.</p>
|
|||
|
<p>Note that over every server in the room, only the ones with support for
|
|||
|
message retention policies will actually remove expired events. This
|
|||
|
support is currently not enabled by default in Synapse.</p>
|
|||
|
<h2 id="note-on-reclaiming-disk-space"><a class="header" href="#note-on-reclaiming-disk-space">Note on reclaiming disk space</a></h2>
|
|||
|
<p>While purge jobs actually delete data from the database, the disk space
|
|||
|
used by the database might not decrease immediately on the database's
|
|||
|
host. However, even though the database engine won't free up the disk
|
|||
|
space, it will start writing new data into where the purged data was.</p>
|
|||
|
<p>If you want to reclaim the freed disk space anyway and return it to the
|
|||
|
operating system, the server admin needs to run <code>VACUUM FULL;</code> (or
|
|||
|
<code>VACUUM;</code> for SQLite databases) on Synapse's database (see the related
|
|||
|
<a href="https://www.postgresql.org/docs/current/sql-vacuum.html">PostgreSQL documentation</a>).</p>

|

|
<h2 id="using-modules"><a class="header" href="#using-modules">Using modules</a></h2>
|
|||
|
<p>To use a module on Synapse, add it to the <code>modules</code> section of the configuration file:</p>

<pre><code class="language-yaml">modules:
|

- module: my_other_super_module.SomeClass
|

config: {}
|

|
</code></pre>
|
|||
|
<p>Each module is defined by a path to a Python class as well as a configuration. This
|
|||
|
information for a given module should be available in the module's own documentation.</p>
|
|||
|
<p><strong>Note</strong>: When using third-party modules, you effectively allow someone else to run
|

|
custom code on your Synapse homeserver. Server admins are encouraged to verify the

|
running malicious code on their instance.</p>
|
|||
|
<p>Also note that we are currently in the process of migrating module interfaces to this
|

system. While some interfaces might be compatible with it, others still require

configuring modules in another part of Synapse's configuration file.</p>

|

|
<p>A module is a Python class that uses Synapse's module API to interact with the
|
|||
|
homeserver. It can register callbacks that Synapse will call on specific operations, as
|
|||
|
well as web resources to attach to Synapse's web server.</p>
|
|||
|
<p>When instantiated, a module is given its parsed configuration as well as an instance of
|
|||
|
the <code>synapse.module_api.ModuleApi</code> class. The configuration is a dictionary, and is
|
|||
|
either the output of the module's <code>parse_config</code> static method (see below), or the
|
|||
|
configuration associated with the module in Synapse's configuration file.</p>
|

|
<p>See the documentation for the <code>ModuleApi</code> class

|
<h2 id="handling-the-modules-configuration"><a class="header" href="#handling-the-modules-configuration">Handling the module's configuration</a></h2>
|
|||
|
<p>A module can implement the following static method:</p>
|
|||
|
<pre><code class="language-python">@staticmethod
|
|||
|
def parse_config(config: dict) -> dict
|
|||
|
</code></pre>
|
|||
|
<p>This method is given a dictionary resulting from parsing the YAML configuration for the
|
|||
|
module. It may modify it (for example by parsing durations expressed as strings (e.g.
|
|||
|
"5d") into milliseconds, etc.), and return the modified dictionary. It may also verify
|
|||
|
that the configuration is correct, and raise an instance of
|
|||
|
<code>synapse.module_api.errors.ConfigError</code> if not.</p>
|
|||
|
<h2 id="registering-a-web-resource"><a class="header" href="#registering-a-web-resource">Registering a web resource</a></h2>
|
|||
|
<p>Modules can register web resources onto Synapse's web server using the following module
|
|||
|
API method:</p>
|
|||
|
<pre><code class="language-python">def ModuleApi.register_web_resource(path: str, resource: IResource) -> None
|
|||
|
</code></pre>
|
|||
|
<p>The path is the full absolute path to register the resource at. For example, if you
|
|||
|
register a resource for the path <code>/_synapse/client/my_super_module/say_hello</code>, Synapse
|
|||
|
will serve it at <code>http(s)://[HS_URL]/_synapse/client/my_super_module/say_hello</code>. Note
|
|||
|
that Synapse does not allow registering resources for several sub-paths in the <code>/_matrix</code>
|
|||
|
namespace (such as anything under <code>/_matrix/client</code> for example). It is strongly
|
|||
|
recommended that modules register their web resources under the <code>/_synapse/client</code>
|
|||
|
namespace.</p>
|
|||
|
<p>The provided resource is a Python class that implements Twisted's <a href="https://twistedmatrix.com/documents/current/api/twisted.web.resource.IResource.html">IResource</a>
|
|||
|
interface (such as <a href="https://twistedmatrix.com/documents/current/api/twisted.web.resource.Resource.html">Resource</a>).</p>
|
|||
|
<p>Only one resource can be registered for a given path. If several modules attempt to
|
|||
|
register a resource for the same path, the module that appears first in Synapse's
|
|||
|
configuration file takes priority.</p>
|
|||
|
<p>Modules <strong>must</strong> register their web resources in their <code>__init__</code> method.</p>

|
|||
|
<p>Modules can use Synapse's module API to register callbacks. Callbacks are functions that
|
|||
|
Synapse will call when performing specific actions. Callbacks must be asynchronous, and
|
|||
|
are split in categories. A single module may implement callbacks from multiple categories,
|
|||
|
and is under no obligation to implement all callbacks from the categories it registers
|
|||
|
callbacks for.</p>
|
|||
|
<p>Modules can register callbacks using one of the module API's <code>register_[...]_callbacks</code>
|
|||
|
methods. The callback functions are passed to these methods as keyword arguments, with
|
|||
|
the callback name as the argument name and the function as its value. This is demonstrated
|
|||
|
in the example below. A <code>register_[...]_callbacks</code> method exists for each category.</p>
|
|||
|
<p>Callbacks for each category can be found on their respective page of the
|
|||
|
<a href="https://matrix-org.github.io/synapse">Synapse documentation website</a>.</p>

<p>Called when processing any incoming event, with the event and a <code>StateMap</code>
|
|||
|
representing the current state of the room the event is being sent into. A <code>StateMap</code> is
|
|||
|
a dictionary that maps tuples containing an event type and a state key to the
|
|||
|
corresponding state event. For example retrieving the room's <code>m.room.create</code> event from
|
|||
|
the <code>state_events</code> argument would look like this: <code>state_events.get(("m.room.create", ""))</code>.
|
|||
|
The module must return a boolean indicating whether the event can be allowed.</p>
|
|||
|
<p>Note that this callback function processes incoming events coming via federation
|
|||
|
traffic (on top of client traffic). This means denying an event might cause the local
|
|||
|
copy of the room's history to diverge from that of remote servers. This may cause
|
|||
|
federation issues in the room. It is strongly recommended to only deny events using this
|
|||
|
callback function if the sender is a local user, or in a private federation in which all
|
|||
|
servers are using the same module, with the same configuration.</p>
|
|||
|
<p>If the boolean returned by the module is <code>True</code>, it may also tell Synapse to replace the
|
|||
|
event with new data by returning the new event's data as a dictionary. In order to do
|
|||
|
that, it is recommended the module calls <code>event.get_dict()</code> to get the current event as a
|
|||
|
dictionary, and modify the returned dictionary accordingly.</p>
|
|||

<p>Note that replacing the event only works for events sent by local users, not for events

received over federation.</p>

|

<p>Account validity callbacks allow module developers to add extra steps to verify the
|
|||
|
validity on an account, i.e. see if a user can be granted access to their account on the
|
|||
|
Synapse instance. Account validity callbacks can be registered using the module API's
|
|||
|
<code>register_account_validity_callbacks</code> method.</p>
|
|||
|
<p>The available account validity callbacks are:</p>
|

|
<h3 id="is_user_expired"><a class="header" href="#is_user_expired"><code>is_user_expired</code></a></h3>
|

|
<pre><code class="language-python">async def is_user_expired(user: str) -> Optional[bool]
|

|
</code></pre>
|

|
<p>Called when processing any authenticated request (except for logout requests). The module
|
|||
|
can return a <code>bool</code> to indicate whether the user has expired and should be locked out of
|
|||
|
their account, or <code>None</code> if the module wasn't able to figure it out. The user is
|
|||
|
represented by their Matrix user ID (e.g. <code>@alice:example.com</code>).</p>
|
|||
|
<p>If the module returns <code>True</code>, the current request will be denied with the error code
|
|||
|
<code>ORG_MATRIX_EXPIRED_ACCOUNT</code> and the HTTP status code 403. Note that this doesn't
|
|||
|
invalidate the user's access token.</p>

|
|||
|
<p>In order to port a module that uses Synapse's old module interface, its author needs to:</p>
|
|||
|
<ul>
|
|||
|
<li>ensure the module's callbacks are all asynchronous.</li>
|
|||
|
<li>register their callbacks using one or more of the <code>register_[...]_callbacks</code> methods
|
|||
|
from the <code>ModuleApi</code> class in the module's <code>__init__</code> method (see <a href="modules/writing_a_module.html#registering-a-callback">this section</a>
|
|||
|
for more info).</li>
|
|||
|
</ul>
|
|||
|
<p>Additionally, if the module is packaged with an additional web resource, the module
|
|||
|
should register this resource in its <code>__init__</code> method using the <code>register_web_resource</code>
|
|||
|
method from the <code>ModuleApi</code> class (see <a href="modules/writing_a_module.html#registering-a-web-resource">this section</a> for
|

more info).</p>
|

|
<p>The module's author should also update any example in the module's configuration to only
|

|
use the new <code>modules</code> section in Synapse's configuration file (see <a href="modules/index.html#using-modules">this section</a>
|

<div id="chapter_begin" style="break-before: page; page-break-before: always;"></div><h1 id="scaling-synapse-via-workers"><a class="header" href="#scaling-synapse-via-workers">Scaling synapse via workers</a></h1>
|
|||
|
<p>For small instances it recommended to run Synapse in the default monolith mode.
|
|||
|
For larger instances where performance is a concern it can be helpful to split
|
|||
|
out functionality into multiple separate python processes. These processes are
|
|||
|
called 'workers', and are (eventually) intended to scale horizontally
|
|||
|
independently.</p>
|
|||
|
<p>Synapse's worker support is under active development and subject to change as
|
|||
|
we attempt to rapidly scale ever larger Synapse instances. However we are
|
|||
|
documenting it here to help admins needing a highly scalable Synapse instance
|
|||
|
similar to the one running <code>matrix.org</code>.</p>
|
|||
|
<p>All processes continue to share the same database instance, and as such,
|
|||
|
workers only work with PostgreSQL-based Synapse deployments. SQLite should only
|
|||
|
be used for demo purposes and any admin considering workers should already be
|
|||
|
running PostgreSQL.</p>
|
|||
|
<p>See also <a href="https://matrix.org/blog/2020/11/03/how-we-fixed-synapses-scalability">Matrix.org blog post</a>
|
|||
|
for a higher level overview.</p>
|
|||
|
<h2 id="main-processworker-communication"><a class="header" href="#main-processworker-communication">Main process/worker communication</a></h2>
|
|||
|
<p>The processes communicate with each other via a Synapse-specific protocol called
|
|||
|
'replication' (analogous to MySQL- or Postgres-style database replication) which
|
|||
|
feeds streams of newly written data between processes so they can be kept in
|
|||
|
sync with the database state.</p>
|
|||
|
<p>When configured to do so, Synapse uses a
|
|||
|
<a href="https://redis.io/topics/pubsub">Redis pub/sub channel</a> to send the replication
|
|||
|
stream between all configured Synapse processes. Additionally, processes may
|
|||
|
make HTTP requests to each other, primarily for operations which need to wait
|
|||
|
for a reply ─ such as sending an event.</p>
|
|||
|
<p>Redis support was added in v1.13.0 with it becoming the recommended method in
|
|||
|
v1.18.0. It replaced the old direct TCP connections (which is deprecated as of
|
|||
|
v1.18.0) to the main process. With Redis, rather than all the workers connecting
|
|||
|
to the main process, all the workers and the main process connect to Redis,
|
|||
|
which relays replication commands between processes. This can give a significant
|
|||
|
cpu saving on the main process and will be a prerequisite for upcoming
|
|||
|
performance improvements.</p>
|
|||
|
<p>If Redis support is enabled Synapse will use it as a shared cache, as well as a
|
|||
|
pub/sub mechanism.</p>
|
|||
|
<p>See the <a href="workers.html#architectural-diagram">Architectural diagram</a> section at the end for
|
|||
|
a visualisation of what this looks like.</p>
|
|||
|
<h2 id="setting-up-workers"><a class="header" href="#setting-up-workers">Setting up workers</a></h2>
|
|||
|
<p>A Redis server is required to manage the communication between the processes.
|
|||
|
The Redis server should be installed following the normal procedure for your
|
|||
|
distribution (e.g. <code>apt install redis-server</code> on Debian). It is safe to use an
|
|||
|
existing Redis deployment if you have one.</p>
|
|||
|
<p>Once installed, check that Redis is running and accessible from the host running
|
|||
|
Synapse, for example by executing <code>echo PING | nc -q1 localhost 6379</code> and seeing
|
|||
|
a response of <code>+PONG</code>.</p>
|
|||
|
<p>The appropriate dependencies must also be installed for Synapse. If using a
|
|||
|
virtualenv, these can be installed with:</p>
|
|||
|
<pre><code class="language-sh">pip install "matrix-synapse[redis]"
|
|||
|
</code></pre>
|
|||
|
<p>Note that these dependencies are included when synapse is installed with <code>pip install matrix-synapse[all]</code>. They are also included in the debian packages from
|
|||
|
<code>matrix.org</code> and in the docker images at
|
|||
|
https://hub.docker.com/r/matrixdotorg/synapse/.</p>
|
|||
|
<p>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. See
|
|||
|
<a href="reverse_proxy.html">the reverse proxy documentation</a> for information on setting up a reverse
|
|||
|
proxy.</p>
|
|||
|
<p>When using workers, each worker process has its own configuration file which
|
|||
|
contains settings specific to that worker, such as the HTTP listener that it
|
|||
|
provides (if any), logging configuration, etc.</p>
|
|||
|
<p>Normally, the worker processes are configured to read from a shared
|
|||
|
configuration file as well as the worker-specific configuration files. This
|
|||
|
makes it easier to keep common configuration settings synchronised across all
|
|||
|
the processes.</p>
|
|||
|
<p>The main process is somewhat special in this respect: it does not normally
|
|||
|
need its own configuration file and can take all of its configuration from the
|
|||
|
shared configuration file.</p>
|
|||
|
<h3 id="shared-configuration"><a class="header" href="#shared-configuration">Shared configuration</a></h3>
|
|||
|
<p>Normally, only a couple of changes are needed to make an existing configuration
|
|||
|
file suitable for use with workers. First, you need to enable an "HTTP replication
|
|||
|
listener" for the main process; and secondly, you need to enable redis-based
|
|||
|
replication. Optionally, a shared secret can be used to authenticate HTTP
|
|||
|
traffic between workers. For example:</p>
|
|||
|
<pre><code class="language-yaml"># extend the existing `listeners` section. This defines the ports that the
|
|||
|
# main process will listen on.
|
|||
|
listeners:
|
|||
|
# The HTTP replication port
|
|||
|
- port: 9093
|
|||
|
bind_address: '127.0.0.1'
|
|||
|
type: http
|
|||
|
resources:
|
|||
|
- names: [replication]
|
|||
|
|
|||
|
# Add a random shared secret to authenticate traffic.
|
|||
|
worker_replication_secret: ""
|
|||
|
|
|||
|
redis:
|
|||
|
enabled: true
|
|||
|
</code></pre>
|
|||
|
<p>See the sample config for the full documentation of each option.</p>
|
|||
|
<p>Under <strong>no circumstances</strong> should the replication listener be exposed to the
|
|||
|
public internet; it has no authentication and is unencrypted.</p>
|
|||
|
<h3 id="worker-configuration"><a class="header" href="#worker-configuration">Worker configuration</a></h3>
|
|||
|
<p>In the config file for each worker, you must specify the type of worker
|
|||
|
application (<code>worker_app</code>), and you should specify a unique name for the worker
|
|||
|
(<code>worker_name</code>). The currently available worker applications are listed below.
|
|||
|
You must also specify the HTTP replication endpoint that it should talk to on
|
|||
|
the main synapse process. <code>worker_replication_host</code> should specify the host of
|
|||
|
the main synapse and <code>worker_replication_http_port</code> should point to the HTTP
|
|||
|
replication port. If the worker will handle HTTP requests then the
|
|||
|
<code>worker_listeners</code> option should be set with a <code>http</code> listener, in the same way
|
|||
|
as the <code>listeners</code> option in the shared config.</p>
|
|||
|
<p>For example:</p>
|
|||
|
<pre><code class="language-yaml">worker_app: synapse.app.generic_worker
|
|||
|
worker_name: worker1
|
|||
|
|
|||
|
# The replication listener on the main synapse process.
|
|||
|
worker_replication_host: 127.0.0.1
|
|||
|
worker_replication_http_port: 9093
|
|||
|
|
|||
|
worker_listeners:
|
|||
|
- type: http
|
|||
|
port: 8083
|
|||
|
resources:
|
|||
|
- names:
|
|||
|
- client
|
|||
|
- federation
|
|||
|
|
|||
|
worker_log_config: /home/matrix/synapse/config/worker1_log_config.yaml
|
|||
|
</code></pre>
|
|||
|
<p>...is a full configuration for a generic worker instance, which will expose a
|
|||
|
plain HTTP endpoint on port 8083 separately serving various endpoints, e.g.
|
|||
|
<code>/sync</code>, which are listed below.</p>
|
|||
|
<p>Obviously you should configure your reverse-proxy to route the relevant
|
|||
|
endpoints to the worker (<code>localhost:8083</code> in the above example).</p>
|
|||
|
<h3 id="running-synapse-with-workers"><a class="header" href="#running-synapse-with-workers">Running Synapse with workers</a></h3>
|
|||
|
<p>Finally, you need to start your worker processes. This can be done with either
|
|||
|
<code>synctl</code> or your distribution's preferred service manager such as <code>systemd</code>. We
|
|||
|
recommend the use of <code>systemd</code> where available: for information on setting up
|
|||
|
<code>systemd</code> to start synapse workers, see
|
|||
|
<a href="systemd-with-workers">Systemd with Workers</a>. To use <code>synctl</code>, see

For multiple workers not handling the SSO endpoints properly, see

|
<a href="https://github.com/matrix-org/synapse/issues/9427">#9427</a>.</p>
|
|||
|
<p>Note that a HTTP listener with <code>client</code> and <code>federation</code> resources must be
|
|||
|
configured in the <code>worker_listeners</code> option in the worker config.</p>
|
|||
|
<h4 id="load-balancing"><a class="header" href="#load-balancing">Load balancing</a></h4>
|
|||
|
<p>It is possible to run multiple instances of this worker app, with incoming requests
|
|||
|
being load-balanced between them by the reverse-proxy. However, different endpoints
|
|||
|
have different characteristics and so admins
|
|||
|
may wish to run multiple groups of workers handling different endpoints so that
|
|||
|
load balancing can be done in different ways.</p>
|
|||
|
<p>For <code>/sync</code> and <code>/initialSync</code> requests it will be more efficient if all
|
|||
|
requests from a particular user are routed to a single instance. Extracting a
|
|||
|
user ID from the access token or <code>Authorization</code> header is currently left as an
|
|||
|
exercise for the reader. Admins may additionally wish to separate out <code>/sync</code>
|
|||
|
requests that have a <code>since</code> query parameter from those that don't (and
|
|||
|
<code>/initialSync</code>), as requests that don't are known as "initial sync" that happens
|
|||
|
when a user logs in on a new device and can be <em>very</em> resource intensive, so
|
|||
|
isolating these requests will stop them from interfering with other users ongoing
|
|||
|
syncs.</p>
|
|||
|
<p>Federation and client requests can be balanced via simple round robin.</p>
|
|||
|
<p>The inbound federation transaction request <code>^/_matrix/federation/v1/send/</code>
|
|||
|
should be balanced by source IP so that transactions from the same remote server
|
|||
|
go to the same process.</p>
|
|||
|
<p>Registration/login requests can be handled separately purely to help ensure that
|
|||
|
unexpected load doesn't affect new logins and sign ups.</p>
|
|||
|
<p>Finally, event sending requests can be balanced by the room ID in the URI (or
|
|||
|
the full URI, or even just round robin), the room ID is the path component after
|
|||
|
<code>/rooms/</code>. If there is a large bridge connected that is sending or may send lots
|
|||
|
of events, then a dedicated set of workers can be provisioned to limit the
|
|||
|
effects of bursts of events from that bridge on events sent by normal users.</p>
|
|||
|
<h4 id="stream-writers"><a class="header" href="#stream-writers">Stream writers</a></h4>
|
|||
|
<p>Additionally, there is <em>experimental</em> support for moving writing of specific
|
|||
|
streams (such as events) off of the main process to a particular worker. (This
|
|||
|
is only supported with Redis-based replication.)</p>
|
|||
|
<p>Currently supported streams are <code>events</code> and <code>typing</code>.</p>
|
|||
|
<p>To enable this, the worker must have a HTTP replication listener configured,
|
|||
|
have a <code>worker_name</code> and be listed in the <code>instance_map</code> config. For example to
|
|||
|
move event persistence off to a dedicated worker, the shared configuration would
|
|||
|
include:</p>
|
|||
|
<pre><code class="language-yaml">instance_map:
|
|||
|
event_persister1:
|
|||
|
host: localhost
|
|||
|
port: 8034
|
|||
|
|
|||
|
stream_writers:
|
|||
|
events: event_persister1
|
|||
|
</code></pre>
|
|||
|
<p>The <code>events</code> stream also experimentally supports having multiple writers, where
|
|||
|
work is sharded between them by room ID. Note that you <em>must</em> restart all worker
|
|||
|
instances when adding or removing event persisters. An example <code>stream_writers</code>
|
|||
|
configuration with multiple writers:</p>
|
|||
|
<pre><code class="language-yaml">stream_writers:
|
|||
|
events:
|
|||
|
- event_persister1
|
|||
|
- event_persister2
|
|||
|
</code></pre>
|
|||
|
<h4 id="background-tasks"><a class="header" href="#background-tasks">Background tasks</a></h4>
|
|||
|
<p>There is also <em>experimental</em> support for moving background tasks to a separate
|
|||
|
worker. Background tasks are run periodically or started via replication. Exactly
|
|||
|
which tasks are configured to run depends on your Synapse configuration (e.g. if
|
|||
|
stats is enabled).</p>
|
|||
|
<p>To enable this, the worker must have a <code>worker_name</code> and can be configured to run
|
|||
|
background tasks. For example, to move background tasks to a dedicated worker,
|
|||
|
the shared configuration would include:</p>
|
|||
|
<pre><code class="language-yaml">run_background_tasks_on: background_worker
|
|||
|
</code></pre>
|
|||
|
<p>You might also wish to investigate the <code>update_user_directory</code> and
|
|||
|
<code>media_instance_running_background_jobs</code> settings.</p>
|
|||
|
<h3 id="synapseapppusher"><a class="header" href="#synapseapppusher"><code>synapse.app.pusher</code></a></h3>

<p>Handles sending push notifications to sygnal and email. Doesn't handle any
|
|||
|
REST endpoints itself, but you should set <code>start_pushers: False</code> in the
|
|||
|
shared configuration file to stop the main synapse sending push notifications.</p>
|
|||
|
<p>To run multiple instances at once the <code>pusher_instances</code> option should list all
|
|||
|
pusher instances by their worker name, e.g.:</p>
|
|||
|
<pre><code class="language-yaml">pusher_instances:
|
|||
|
- pusher_worker1
|
|||
|
- pusher_worker2
|

|
</code></pre>
|
|||
|
<h3 id="synapseappappservice"><a class="header" href="#synapseappappservice"><code>synapse.app.appservice</code></a></h3>
|
|||
|
<p>Handles sending output traffic to Application Services. Doesn't handle any
|
|||
|
REST endpoints itself, but you should set <code>notify_appservices: False</code> in the
|
|||
|
shared configuration file to stop the main synapse sending appservice notifications.</p>
|
|||
|
<p>Note this worker cannot be load-balanced: only one instance should be active.</p>
|
|||
|
<h3 id="synapseappfederation_sender"><a class="header" href="#synapseappfederation_sender"><code>synapse.app.federation_sender</code></a></h3>
|
|||
|
<p>Handles sending federation traffic to other servers. Doesn't handle any
|
|||
|
REST endpoints itself, but you should set <code>send_federation: False</code> in the
|
|||
|
shared configuration file to stop the main synapse sending this traffic.</p>
|
|||
|
<p>If running multiple federation senders then you must list each
|
|||
|
instance in the <code>federation_sender_instances</code> option by their <code>worker_name</code>.
|
|||
|
All instances must be stopped and started when adding or removing instances.
|
|||
|
For example:</p>
|
|||
|
<pre><code class="language-yaml">federation_sender_instances:
|
|||
|
- federation_sender1
|
|||
|
- federation_sender2
|

</code></pre>

|
<h3 id="synapseappmedia_repository"><a class="header" href="#synapseappmedia_repository"><code>synapse.app.media_repository</code></a></h3>
|

|
<p>Handles the media repository. It can handle all endpoints starting with:</p>
|
|||
|
<pre><code>/_matrix/media/
|
|||
|
</code></pre>
|
|||
|
<p>... and the following regular expressions matching media-specific administration APIs:</p>
|

|
<pre><code>^/_synapse/admin/v1/purge_media_cache$
|
|||
|
^/_synapse/admin/v1/room/.*/media.*$
|

^/_synapse/admin/v1/user/.*/media.*$
|
|||
|
^/_synapse/admin/v1/media/.*$
|
|||
|
^/_synapse/admin/v1/quarantine_media/.*$
|
|||
|
^/_synapse/admin/v1/users/.*/media$
|
|||
|
</code></pre>
|
|||
|
<p>You should also set <code>enable_media_repo: False</code> in the shared configuration
|
|||
|
file to stop the main synapse running background jobs related to managing the
|
|||
|
media repository. Note that doing so will prevent the main process from being
|
|||
|
able to handle the above endpoints.</p>
|
|||
|
<p>In the <code>media_repository</code> worker configuration file, configure the http listener to
|
|||
|
expose the <code>media</code> resource. For example:</p>
|
|||
|
<pre><code class="language-yaml"> worker_listeners:
|
|||
|
- type: http
|
|||
|
port: 8085
|
|||
|
resources:
|
|||
|
- names:
|
|||
|
- media
|
|||
|
</code></pre>
|
|||
|
<p>Note that if running multiple media repositories they must be on the same server
|
|||
|
and you must configure a single instance to run the background tasks, e.g.:</p>
|
|||
|
<pre><code class="language-yaml"> media_instance_running_background_jobs: "media-repository-1"
|
|||
|
</code></pre>
|
|||
|
<p>Note that if a reverse proxy is used , then <code>/_matrix/media/</code> must be routed for both inbound client and federation requests (if they are handled separately).</p>
|
|||
|
<h3 id="synapseappuser_dir"><a class="header" href="#synapseappuser_dir"><code>synapse.app.user_dir</code></a></h3>
|
|||
|
<p>Handles searches in the user directory. It can handle REST endpoints matching
|
|||
|
the following regular expressions:</p>
|
|||
|
<pre><code>^/_matrix/client/(api/v1|r0|unstable)/user_directory/search$
|
|||
|
</code></pre>
|
|||
|
<p>When using this worker you must also set <code>update_user_directory: False</code> in the
|
|||
|
shared configuration file to stop the main synapse running background
|
|||
|
jobs related to updating the user directory.</p>
|
|||
|
<h3 id="synapseappfrontend_proxy"><a class="header" href="#synapseappfrontend_proxy"><code>synapse.app.frontend_proxy</code></a></h3>
|
|||
|
<p>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:</p>
|
|||
|
<pre><code>^/_matrix/client/(api/v1|r0|unstable)/keys/upload
|
|||
|
</code></pre>
|
|||
|
<p>If <code>use_presence</code> is False in the homeserver config, it can also handle REST
|
|||
|
endpoints matching the following regular expressions:</p>
|
|||
|
<pre><code>^/_matrix/client/(api/v1|r0|unstable)/presence/[^/]+/status
|
|||
|
</code></pre>
|
|||
|
<p>This "stub" presence handler will pass through <code>GET</code> request but make the
|
|||
|
<code>PUT</code> effectively a no-op.</p>
|
|||
|
<p>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 <code>worker_main_http_uri</code> setting in the <code>frontend_proxy</code> worker configuration
|
|||
|
file. For example:</p>
|

|
<pre><code>worker_main_http_uri: http://127.0.0.1:8008
|

</code></pre>
|

<h3 id="historical-apps"><a class="header" href="#historical-apps">Historical apps</a></h3>
|

|
<p><em>Note:</em> Historically there used to be more apps, however they have been
|

|
amalgamated into a single <code>synapse.app.generic_worker</code> app. The remaining apps
|
|||
|
are ones that do specific processing unrelated to requests, e.g. the <code>pusher</code>
|
|||
|
that handles sending out push notifications for new events. The intention is for
|
|||
|
all these to be folded into the <code>generic_worker</code> app and to use config to define
|
|||
|
which processes handle the various proccessing such as push notifications.</p>

<h2 id="migration-from-old-config"><a class="header" href="#migration-from-old-config">Migration from old config</a></h2>
|
|||
|
<p>There are two main independent changes that have been made: introducing Redis
|
|||
|
support and merging apps into <code>synapse.app.generic_worker</code>. Both these changes
|
|||
|
are backwards compatible and so no changes to the config are required, however
|
|||
|
server admins are encouraged to plan to migrate to Redis as the old style direct
|
|||
|
TCP replication config is deprecated.</p>
|
|||
|
<p>To migrate to Redis add the <code>redis</code> config as above, and optionally remove the
|

TCP <code>replication</code> listener from master and <code>worker_replication_port</code> from worker

|
config.</p>
|

|
<p>To migrate apps to use <code>synapse.app.generic_worker</code> simply update the

in systemd service files, but not required for synctl).</p>

|
|||
|
<p>If you want to use <code>synctl</code> to manage your synapse processes, you will need to
|
|||
|
create an an additional configuration file for the main synapse process. That
|
|||
|
configuration should look like this:</p>
|
|||
|
<pre><code class="language-yaml">worker_app: synapse.app.homeserver
|
|||
|
</code></pre>
|
|||
|
<p>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:</p>
|
|||
|
<pre><code class="language-yaml">worker_pid_file: /home/matrix/synapse/worker1.pid
|
|||
|
</code></pre>
|
|||
|
<p>Finally, to actually run your worker-based synapse, you must pass synctl the <code>-a</code>
|
|||
|
commandline option to tell it to operate on all the worker configurations found
|
|||
|
in the given directory, e.g.:</p>
|
|||
|
<pre><code>synctl -a $CONFIG/workers start
|
|||
|
</code></pre>
|
|||
|
<p>Currently one should always restart all workers when restarting or upgrading
|
|||
|
synapse, unless you explicitly know it's safe not to. For instance, restarting
|
|||
|
synapse without restarting all the synchrotrons may result in broken typing
|
|||
|
notifications.</p>
|
|||
|
<p>To manipulate a specific worker, you pass the -w option to synctl:</p>
|
|||
|
<pre><code>synctl -w $CONFIG/workers/worker1.yaml restart
|
|||
|
</code></pre>

<p>A new server admin user can also be created using the <code>register_new_matrix_user</code>
|
|||
|
command. This is a script that is located in the <code>scripts/</code> directory, or possibly
|
|||
|
already on your <code>$PATH</code> depending on how Synapse was installed.</p>
|
|||
|
<p>Finding your user's <code>access_token</code> is client-dependent, but will usually be shown in the client's settings.</p>

<p>Once you have your <code>access_token</code>, you will need to authenticate each request to an Admin API endpoint by
|

|
providing the token as either a query parameter or a request header. To add it as a request header in cURL:</p>
|
|||
|
<pre><code class="language-sh">curl --header "Authorization: Bearer <access_token>" <the_rest_of_your_API_request>

|
|||
|
<li><code>deleted</code>: integer - The number of media items successfully deleted</li>
|

|
</ul>
|
|||
|
<p>To use it, you will need to authenticate by providing an <code>access_token</code> for a
|
|||
|
server admin: see <a href="admin_api/../usage/administration/admin_api">Admin API</a>.</p>
|

<div id="chapter_begin" style="break-before: page; page-break-before: always;"></div><h1 id="purge-history-api"><a class="header" href="#purge-history-api">Purge History API</a></h1>
|
|||
|
<p>The purge history API allows server admins to purge historic events from their
|
|||
|
database, reclaiming disk space.</p>
|
|||
|
<p>Depending on the amount of history being purged a call to the API may take
|
|||
|
several minutes or longer. During this period users will not be able to
|
|||
|
paginate further back in the room from the point being purged from.</p>
|
|||
|
<p>Note that Synapse requires at least one message in each room, so it will never
|
|||
|
delete the last message in a room.</p>
|
|||
|
<p>The API is:</p>
|
|||
|
<pre><code>POST /_synapse/admin/v1/purge_history/<room_id>[/<event_id>]
|
|||
|
</code></pre>
|
|||
|
<p>To use it, you will need to authenticate by providing an <code>access_token</code> for a
|
|||
|
server admin: <a href="admin_api/../usage/administration/admin_api">Admin API</a></p>
|
|||
|
<p>By default, events sent by local users are not deleted, as they may represent
|
|||
|
the only copies of this content in existence. (Events sent by remote users are
|
|||
|
deleted.)</p>
|
|||
|
<p>Room state data (such as joins, leaves, topic) is always preserved.</p>
|
|||
|
<p>To delete local message events as well, set <code>delete_local_events</code> in the body:</p>
|
|||
|
<pre><code>{
|
|||
|
"delete_local_events": true
|
|||
|
}
|
|||
|
</code></pre>
|
|||
|
<p>The caller must specify the point in the room to purge up to. This can be
|
|||
|
specified by including an event_id in the URI, or by setting a
|
|||
|
<code>purge_up_to_event_id</code> or <code>purge_up_to_ts</code> in the request body. If an event
|
|||
|
id is given, that event (and others at the same graph depth) will be retained.
|
|||
|
If <code>purge_up_to_ts</code> is given, it should be a timestamp since the unix epoch,
|
|||
|
in milliseconds.</p>
|
|||
|
<p>The API starts the purge running, and returns immediately with a JSON body with
|
|||
|
a purge id:</p>
|
|||
|
<pre><code class="language-json">{
|
|||
|

<pre><code>GET /_synapse/admin/v1/purge_history_status/<purge_id>
|

|
|||
|
<p>Again, you will need to authenticate by providing an <code>access_token</code> for a
|

server admin.</p>
|

|
<p>This API returns a JSON body like the following:</p>
|

|
|||
|
<p>This API allows for the creation of users in an administrative and
|
|||
|
non-interactive way. This is generally used for bootstrapping a Synapse
|
|||
|
instance with administrator accounts.</p>
|
|||
|
<p>To authenticate yourself to the server, you will need both the shared secret
|
|||
|
(<code>registration_shared_secret</code> in the homeserver configuration), and a
|
|||
|
one-time nonce. If the registration shared secret is not configured, this API
|
|||
|
is not enabled.</p>
|
|||
|
<p>To fetch the nonce, you need to request one from the API:</p>
|
|||
|
<pre><code>> GET /_synapse/admin/v1/register
|
|||
|
|
|||
|
< {"nonce": "thisisanonce"}
|
|||
|
</code></pre>
|
|||
|
<p>Once you have the nonce, you can make a <code>POST</code> to the same URL with a JSON
|
|||
|
body containing the nonce, username, password, whether they are an admin
|
|||
|
(optional, False by default), and a HMAC digest of the content. Also you can
|
|||
|
set the displayname (optional, <code>username</code> by default).</p>
|
|||
|
<p>As an example:</p>
|
|||
|
<pre><code>> POST /_synapse/admin/v1/register
|
|||
|
> {
|
|||
|
"nonce": "thisisanonce",
|
|||
|
"username": "pepper_roni",
|
|||
|
"displayname": "Pepper Roni",
|
|||
|
"password": "pizza",
|
|||
|
"admin": true,
|
|||
|
"mac": "mac_digest_here"

|
|

|

|
"device_id": "device_id_here"
|
|||
|
}
|
|||
|
</code></pre>
|
|||
|
<p>The MAC is the hex digest output of the HMAC-SHA1 algorithm, with the key being
|
|||
|
the shared secret and the content being the nonce, user, password, either the
|
|||
|
string "admin" or "notadmin", and optionally the user_type
|
|||
|
each separated by NULs. For an example of generation in Python:</p>
|
|||
|
<pre><code class="language-python">import hmac, hashlib
|
|||
|
|
|||
|
def generate_mac(nonce, user, password, admin=False, user_type=None):

mac = hmac.new(

)
|
|||
|
|

|
mac.update(nonce.encode('utf8'))
|

mac.update(b"\x00")
|

|

|
<p>This API allows you to manage tokens which can be used to authenticate
|
|||
|
registration requests, as proposed in <a href="https://github.com/govynnus/matrix-doc/blob/token-registration/proposals/3231-token-authenticated-registration.md">MSC3231</a>.
|
|||
|
To use it, you will need to enable the <code>registration_requires_token</code> config
|
|||
|
option, and authenticate by providing an <code>access_token</code> for a server admin:
|
|||
|
see <a href="usage/administration/admin_api/../../usage/administration/admin_api">Admin API</a>.
|
|||
|
Note that this API is still experimental; not all clients may support it yet.</p>
|
|||
|
<h2 id="registration-token-objects"><a class="header" href="#registration-token-objects">Registration token objects</a></h2>
|
|||
|
<p>Most endpoints make use of JSON objects that contain details about tokens.
|
|||
|
These objects have the following fields:</p>
|
|||
|
<ul>
|
|||
|
<li><code>token</code>: The token which can be used to authenticate registration.</li>
|
|||
|
<li><code>uses_allowed</code>: The number of times the token can be used to complete a
|
|||
|
registration before it becomes invalid.</li>
|
|||
|
<li><code>pending</code>: The number of pending uses the token has. When someone uses
|
|||
|
the token to authenticate themselves, the pending counter is incremented
|
|||
|
so that the token is not used more than the permitted number of times.
|
|||
|
When the person completes registration the pending counter is decremented,
|
|||
|
and the completed counter is incremented.</li>
|
|||
|
<li><code>completed</code>: The number of times the token has been used to successfully
|
|||
|
complete a registration.</li>
|
|||
|
<li><code>expiry_time</code>: The latest time the token is valid. Given as the number of
|
|||
|
milliseconds since 1970-01-01 00:00:00 UTC (the start of the Unix epoch).
|
|||
|
To convert this into a human-readable form you can remove the milliseconds
|
|||
|
and use the <code>date</code> command. For example, <code>date -d '@1625394937'</code>.</li>

<p>The Delete Room admin API allows server admins to remove rooms from server

and block these rooms.</p>
|

|
<p>Shuts down a room. Moves all local users and room aliases automatically to a
|
|||
|
new room if <code>new_room_user_id</code> is set. Otherwise local users only
|
|||
|
leave the room without any information.</p>
|
|||
|
<p>The new room will be created with the user specified by the <code>new_room_user_id</code> parameter
|
|||
|
as room administrator and will contain a message explaining what happened. Users invited
|
|||
|
to the new room will have power level <code>-10</code> by default, and thus be unable to speak.</p>
|
|||
|
<p>If <code>block</code> is <code>True</code> it prevents new joins to the old room.</p>
|
|||
|
<p>This API will remove all trace of the old room from your database after removing
|
|||
|
all local users. If <code>purge</code> is <code>true</code> (the default), all traces of the old room will
|
|||
|
be removed from your database after removing all local users. If you do not want
|
|||
|
this to happen, set <code>purge</code> to <code>false</code>.
|
|||
|
Depending on the amount of history being purged a call to the API may take
|
|||
|
several minutes or longer.</p>
|
|||
|
<p>The local server will only have the power to move local user and room aliases to
|
|||
|
the new room. Users on other servers will be unaffected.</p>
|
|||
|
<p>The API is:</p>

<li><code>room_id</code> - The ID of the room.</li>
|

|
|||
|
<p>The following JSON body parameters are available:</p>
|
|||
|
<ul>
|
|||
|
<li><code>new_room_user_id</code> - Optional. If set, a new room will be created with this user ID
|
|||
|
as the creator and admin, and all users in the old room will be moved into that
|
|||
|
room. If not set, no new room will be created and the users will just be removed
|
|||
|
from the old room. The user ID must be on the local server, but does not necessarily
|
|||
|
have to belong to a registered user.</li>
|
|||
|
<li><code>room_name</code> - Optional. A string representing the name of the room that new users will be
|
|||
|
invited to. Defaults to <code>Content Violation Notification</code></li>
|
|||
|
<li><code>message</code> - Optional. A string containing the first message that will be sent as
|
|||
|
<code>new_room_user_id</code> in the new room. Ideally this will clearly convey why the
|
|||
|
original room was shut down. Defaults to <code>Sharing illegal content on this server is not permitted and rooms in violation will be blocked.</code></li>
|
|||
|
<li><code>block</code> - Optional. If set to <code>true</code>, this room will be added to a blocking list, preventing
|
|||
|
future attempts to join the room. Defaults to <code>false</code>.</li>
|
|||
|
<li><code>purge</code> - Optional. If set to <code>true</code>, it will remove all traces of the room from your database.
|
|||
|
Defaults to <code>true</code>.</li>
|
|||
|
<li><code>force_purge</code> - Optional, and ignored unless <code>purge</code> is <code>true</code>. If set to <code>true</code>, it
|
|||
|
will force a purge to go ahead even if there are local users still in the room. Do not
|
|||
|
use this unless a regular <code>purge</code> operation fails, as it could leave those users'
|
|||
|
clients in a confused state.</li>
|
|||
|
</ul>
|
|||
|
<p>The JSON body must not be empty. The body must be at least <code>{}</code>.</p>
|
|||
|
<p><strong>Response</strong></p>
|
|||
|
<p>The following fields are returned in the JSON response body:</p>

|
|||
|
<li><code>failed_to_kick_users</code> - An array of users (<code>user_id</code>) that that were not kicked.</li>
|
|||
|
<li><code>local_aliases</code> - An array of strings representing the local aliases that were migrated from
|
|||
|

<h2 id="undoing-room-deletions"><a class="header" href="#undoing-room-deletions">Undoing room deletions</a></h2>
|
|||
|
<p><em>Note</em>: This guide may be outdated by the time you read it. By nature of room deletions being performed at the database level,
|
|||
|
the structure can and does change without notice.</p>
|
|||
|
<p>First, it's important to understand that a room deletion is very destructive. Undoing a deletion is not as simple as pretending it
|
|||
|
never happened - work has to be done to move forward instead of resetting the past. In fact, in some cases it might not be possible
|
|||
|
to recover at all:</p>
|
|||
|
<ul>
|
|||
|
<li>If the room was invite-only, your users will need to be re-invited.</li>
|
|||
|
<li>If the room no longer has any members at all, it'll be impossible to rejoin.</li>
|
|||
|
<li>The first user to rejoin will have to do so via an alias on a different
|
|||
|
server (or receive an invite from a user on a different server).</li>
|
|||
|
</ul>
|
|||
|
<p>With all that being said, if you still want to try and recover the room:</p>
|
|||
|
<ol>
|
|||
|
<li>
|
|||
|
<p>If the room was <code>block</code>ed, you must unblock it on your server. This can be
|
|||
|
accomplished as follows:</p>
|
|||
|
<ol>
|
|||
|
<li>For safety reasons, shut down Synapse.</li>
|
|||
|
<li>In the database, run <code>DELETE FROM blocked_rooms WHERE room_id = '!example:example.org';</code>
|
|||
|
<ul>
|
|||
|
<li>For caution: it's recommended to run this in a transaction: <code>BEGIN; DELETE ...;</code>, verify you got 1 result, then <code>COMMIT;</code>.</li>
|
|||
|
<li>The room ID is the same one supplied to the delete room API, not the Content Violation room.</li>
|
|||
|
</ul>
|
|||
|
</li>
|
|||
|
<li>Restart Synapse.</li>
|
|||
|
</ol>
|
|||
|
<p>This step is unnecessary if <code>block</code> was not set.</p>
|
|||
|
</li>
|
|||
|
<li>
|
|||
|
<p>Any room aliases on your server that pointed to the deleted room may have
|
|||
|
been deleted, or redirected to the Content Violation room. These will need
|
|||
|
to be restored manually.</p>
|
|||
|
</li>
|
|||
|
<li>
|
|||
|
<p>Users on your server that were in the deleted room will have been kicked
|
|||
|
from the room. Consider whether you want to update their membership
|
|||
|
(possibly via the <a href="admin_api/room_membership.html">Edit Room Membership API</a>) or let
|
|||
|
them handle rejoining themselves.</p>
|
|||
|
</li>
|
|||
|
<li>
|
|||
|
<p>If <code>new_room_user_id</code> was given, a 'Content Violation' will have been
|
|||
|
created. Consider whether you want to delete that roomm.</p>
|
|||
|
</li>

|
<li>
|
|||
|
<p><code>user_id</code> - Is optional and filters to only return users with user IDs
|

|
that contain this value. This parameter is ignored when using the <code>name</code> parameter.</p>
|

|
<li>
|

|
<p><code>name</code> - Is optional and filters to only return users with user ID localparts
|

|
<strong>or</strong> displaynames that contain this value.</p>
|
|||
|
</li>
|
|||
|
<li>
|
|||
|
<p><code>guests</code> - string representing a bool - Is optional and if <code>false</code> will <strong>exclude</strong> guest users.
|
|||
|
Defaults to <code>true</code> to include guest users.</p>
|
|||
|
</li>
|
|||
|
<li>
|
|||
|
<p><code>deactivated</code> - string representing a bool - Is optional and if <code>true</code> will <strong>include</strong> deactivated users.
|
|||
|
Defaults to <code>false</code> to exclude deactivated users.</p>
|
|||
|
</li>
|
|||
|
<li>
|
|||
|
<p><code>limit</code> - string representing a positive integer - Is optional but is used for pagination,
|
|||
|
denoting the maximum number of items to return in this call. Defaults to <code>100</code>.</p>
|
|||
|
</li>
|
|||
|
<li>
|
|||
|
<p><code>from</code> - string representing a positive integer - Is optional but used for pagination,
|
|||
|
denoting the offset in the returned results. This should be treated as an opaque value and
|
|||
|
not explicitly set to anything other than the return value of <code>next_token</code> from a previous call.
|
|||
|
Defaults to <code>0</code>.</p>
|
|||
|
</li>
|
|||
|
<li>
|
|||
|
<p><code>order_by</code> - The method by which to sort the returned list of users.
|
|||
|
If the ordered field has duplicates, the second order is always by ascending <code>name</code>,
|
|||
|
which guarantees a stable ordering. Valid values are:</p>
|
|||
|
<ul>
|
|||
|
<li><code>name</code> - Users are ordered alphabetically by <code>name</code>. This is the default.</li>
|
|||
|
<li><code>is_guest</code> - Users are ordered by <code>is_guest</code> status.</li>
|
|||
|
<li><code>admin</code> - Users are ordered by <code>admin</code> status.</li>
|
|||
|
<li><code>user_type</code> - Users are ordered alphabetically by <code>user_type</code>.</li>
|
|||
|
<li><code>deactivated</code> - Users are ordered by <code>deactivated</code> status.</li>
|
|||
|
<li><code>shadow_banned</code> - Users are ordered by <code>shadow_banned</code> status.</li>
|
|||
|
<li><code>displayname</code> - Users are ordered alphabetically by <code>displayname</code>.</li>
|
|||
|
<li><code>avatar_url</code> - Users are ordered alphabetically by avatar URL.</li>
|
|||
|
<li><code>creation_ts</code> - Users are ordered by when the users was created in ms.</li>
|
|||
|
</ul>
|
|||
|
</li>
|
|||
|
<li>
|
|||
|
<p><code>dir</code> - Direction of media order. Either <code>f</code> for forwards or <code>b</code> for backwards.
|
|||
|
Setting this value to <code>b</code> will reverse the above sort order. Defaults to <code>f</code>.</p>
|
|||
|
</li>
|
|||
|
</ul>
|
|||
|
<p>Caution. The database only has indexes on the columns <code>name</code> and <code>creation_ts</code>.
|
|||
|
This means that if a different sort order is used (<code>is_guest</code>, <code>admin</code>,
|
|||
|
<code>user_type</code>, <code>deactivated</code>, <code>shadow_banned</code>, <code>avatar_url</code> or <code>displayname</code>),
|
|||
|
this can cause a large load on the database, especially for large environments.</p>

<p>To paginate, check for <code>next_token</code> and if present, call the endpoint again
|

with <code>from</code> set to the value of <code>next_token</code>. This will return a new page.</p>

<p>If the endpoint does not return a <code>next_token</code> then there are no more
|

reports to paginate through.</p>
|

|
<p><strong>Parameters</strong></p>
|
|||
|
<p>The following parameters should be set in the URL:</p>
|
|||
|
<ul>
|
|||
|
<li>
|
|||
|
<p><code>user_id</code> - string - fully qualified: for example, <code>@user:server.com</code>.</p>
|
|||
|
</li>
|
|||
|
<li>
|
|||
|
<p><code>limit</code>: string representing a positive integer - Is optional but is used for pagination,
|
|||
|
denoting the maximum number of items to return in this call. Defaults to <code>100</code>.</p>
|
|||
|
</li>
|
|||
|
<li>
|
|||
|
<p><code>from</code>: string representing a positive integer - Is optional but used for pagination,
|
|||
|
denoting the offset in the returned results. This should be treated as an opaque value and
|
|||
|
not explicitly set to anything other than the return value of <code>next_token</code> from a previous call.
|
|||
|
Defaults to <code>0</code>.</p>
|
|||
|
</li>
|
|||
|
<li>
|
|||
|
<p><code>order_by</code> - The method by which to sort the returned list of media.
|
|||
|
If the ordered field has duplicates, the second order is always by ascending <code>media_id</code>,
|
|||
|
which guarantees a stable ordering. Valid values are:</p>
|
|||
|
<ul>
|
|||
|
<li><code>media_id</code> - Media are ordered alphabetically by <code>media_id</code>.</li>
|
|||
|
<li><code>upload_name</code> - Media are ordered alphabetically by name the media was uploaded with.</li>
|
|||
|
<li><code>created_ts</code> - Media are ordered by when the content was uploaded in ms.
|
|||
|
Smallest to largest. This is the default.</li>
|
|||
|
<li><code>last_access_ts</code> - Media are ordered by when the content was last accessed in ms.
|
|||
|
Smallest to largest.</li>
|
|||
|
<li><code>media_length</code> - Media are ordered by length of the media in bytes.
|
|||
|
Smallest to largest.</li>
|
|||
|
<li><code>media_type</code> - Media are ordered alphabetically by MIME-type.</li>
|
|||
|
<li><code>quarantined_by</code> - Media are ordered alphabetically by the user ID that
|
|||
|
initiated the quarantine request for this media.</li>
|
|||
|
<li><code>safe_from_quarantine</code> - Media are ordered by the status if this media is safe
|
|||
|
from quarantining.</li>
|
|||
|
</ul>
|
|||
|
</li>
|
|||
|
<li>
|
|||
|
<p><code>dir</code> - Direction of media order. Either <code>f</code> for forwards or <code>b</code> for backwards.
|
|||
|
Setting this value to <code>b</code> will reverse the above sort order. Defaults to <code>f</code>.</p>
|
|||
|
</li>
|
|||
|
</ul>
|
|||
|
<p>If neither <code>order_by</code> nor <code>dir</code> is set, the default order is newest media on top
|
|||
|
(corresponds to <code>order_by</code> = <code>created_ts</code> and <code>dir</code> = <code>b</code>).</p>
|
|||
|
<p>Caution. The database only has indexes on the columns <code>media_id</code>,
|
|||
|
<code>user_id</code> and <code>created_ts</code>. This means that if a different sort order is used
|
|||
|
(<code>upload_name</code>, <code>last_access_ts</code>, <code>media_length</code>, <code>media_type</code>,
|
|||
|
<code>quarantined_by</code> or <code>safe_from_quarantine</code>), this can cause a large load on the
|
|||
|
database, especially for large environments.</p>

<h3 id="delete-media-uploaded-by-a-user-1"><a class="header" href="#delete-media-uploaded-by-a-user-1">Delete media uploaded by a user</a></h3>
|
|||
|
<p>This API deletes the <em>local</em> media from the disk of your own server
|
|||
|
that a specific <code>user_id</code> has created. This includes any local thumbnails.</p>
|
|||
|
<p>This API will not affect media that has been uploaded to external
|
|||
|
media repositories (e.g https://github.com/turt2live/matrix-media-repo/).</p>
|
|||
|
<p>By default, the API deletes media ordered by descending creation date and ascending media ID.
|
|||
|
The newest media is deleted first. You can change the order with parameters
|
|||
|
<code>order_by</code> and <code>dir</code>. If no <code>limit</code> is set the API deletes <code>100</code> files per request.</p>
|
|||
|
<p>The API is:</p>
|
|||
|
<pre><code>DELETE /_synapse/admin/v1/users/<user_id>/media
|
|||
|
</code></pre>
|
|||
|
<p>To use it, you will need to authenticate by providing an <code>access_token</code> for a
|
|||
|
server admin: <a href="admin_api/../usage/administration/admin_api">Admin API</a></p>
|
|||
|
<p>A response body like the following is returned:</p>
|
|||
|
<pre><code class="language-json">{
|
|||
|
"deleted_media": [
|
|||
|
"abcdefghijklmnopqrstuvwx"
|
|||
|
],
|
|||
|
"total": 1
|
|||
|
}
|
|||
|
</code></pre>
|
|||
|
<p>The following fields are returned in the JSON response body:</p>
|
|||
|
<ul>
|
|||
|
<li><code>deleted_media</code>: an array of strings - List of deleted <code>media_id</code></li>
|
|||
|
<li><code>total</code>: integer - Total number of deleted <code>media_id</code></li>
|
|||
|
</ul>
|
|||
|
<p><strong>Note</strong>: There is no <code>next_token</code>. This is not useful for deleting media, because
|
|||
|
after deleting media the remaining media have a new order.</p>
|
|||
|
<p><strong>Parameters</strong></p>
|
|||
|
<p>This API has the same parameters as
|
|||
|
<a href="admin_api/user_admin_api.html#list-media-uploaded-by-a-user">List media uploaded by a user</a>.
|
|||
|
With the parameters you can for example limit the number of files to delete at once or
|
|||
|
delete largest/smallest or newest/oldest files first.</p>
|
|||
|
<h2 id="login-as-a-user"><a class="header" href="#login-as-a-user">Login as a user</a></h2>
|

|
<p>Get an access token that can be used to authenticate as that user. Useful for
|

|
when admins wish to do actions on behalf of a user.</p>
|
|||
|
<p>The API is:</p>
|
|||
|
<pre><code>POST /_synapse/admin/v1/users/<user_id>/login
|
|||
|
{}
|
|||
|
</code></pre>
|
|||
|
<p>An optional <code>valid_until_ms</code> field can be specified in the request body as an
|
|||
|
integer timestamp that specifies when the token should expire. By default tokens
|
|||
|
do not expire.</p>
|
|||
|
<p>A response body like the following is returned:</p>
|
|||
|
<pre><code class="language-json">{
|
|||
|
"access_token": "<opaque_access_token_string>"
|
|||
|
}
|
|||
|
</code></pre>
|
|||
|
<p>This API does <em>not</em> generate a new device for the user, and so will not appear
|
|||
|
their <code>/devices</code> list, and in general the target user should not be able to
|
|||
|
tell they have been logged in as.</p>
|
|||
|
<p>To expire the token call the standard <code>/logout</code> API with the token.</p>
|
|||
|
<p>Note: The token will expire if the <em>admin</em> user calls <code>/logout/all</code> from any
|
|||
|
of their devices, but the token will <em>not</em> expire if the target user does the
|
|||
|
same.</p>

<h2 id="shadow-banning-users"><a class="header" href="#shadow-banning-users">Shadow-banning users</a></h2>
|
|||
|
<p>Shadow-banning is a useful tool for moderating malicious or egregiously abusive users.
|
|||
|
A shadow-banned users receives successful responses to their client-server API requests,
|
|||
|
but the events are not propagated into rooms. This can be an effective tool as it
|
|||
|
(hopefully) takes longer for the user to realise they are being moderated before
|
|||
|
pivoting to another account.</p>
|
|||
|
<p>Shadow-banning a user should be used as a tool of last resort and may lead to confusing
|
|||
|
or broken behaviour for the client. A shadow-banned user will not receive any
|
|||
|
notification and it is generally more appropriate to ban or kick abusive users.
|
|||
|
A shadow-banned user will be unable to contact anyone on the server.</p>
|
|||
|
<p>The API is:</p>
|
|||
|
<pre><code>POST /_synapse/admin/v1/users/<user_id>/shadow_ban
|
|||
|
</code></pre>
|
|||
|

|
|||
|
server admin: <a href="admin_api/../usage/administration/admin_api">Admin API</a></p>

|

<p>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.</p>
|
|||
|
<p><strong><em>Security Warning</em></strong></p>
|
|||
|
<p>Note that this will give administrative access to synapse to <strong>all users</strong> with
|
|||
|
shell access to the server. It should therefore <strong>not</strong> be enabled in
|
|||
|
environments where untrusted users have shell access.</p>

<li>
|

<p>Install Prometheus:</p>
|

|
<p>Follow instructions at

<a href="http://prometheus.io/docs/introduction/install/">http://prometheus.io/docs/introduction/install/</a></p>

</li>
|

|
<li>
|
|||
|
<p>Enable Synapse metrics:</p>
|
|||
|
<p>There are two methods of enabling metrics in Synapse.</p>
|
|||
|
<p>The first serves the metrics as a part of the usual web server and
|
|||
|
can be enabled by adding the "metrics" resource to the existing
|
|||
|
listener as such:</p>
|
|||
|
<pre><code class="language-yaml"> resources:
|
|||
|
- names:
|
|||
|
- client
|
|||
|
- metrics
|
|||
|
</code></pre>
|
|||
|
<p>This provides a simple way of adding metrics to your Synapse
|
|||
|
installation, and serves under <code>/_synapse/metrics</code>. If you do not
|
|||
|
wish your metrics be publicly exposed, you will need to either
|
|||
|
filter it out at your load balancer, or use the second method.</p>
|
|||
|
<p>The second method runs the metrics server on a different port, in a
|
|||
|
different thread to Synapse. This can make it more resilient to
|
|||
|
heavy load meaning metrics cannot be retrieved, and can be exposed
|
|||
|
to just internal networks easier. The served metrics are available
|
|||
|
over HTTP only, and will be available at <code>/_synapse/metrics</code>.</p>
|
|||
|
<p>Add a new listener to homeserver.yaml:</p>
|
|||
|
<pre><code class="language-yaml"> listeners:
|
|||
|
- type: metrics
|
|||
|
port: 9000
|
|||
|
bind_addresses:
|
|||
|
- '0.0.0.0'
|
|||
|
</code></pre>
|
|||
|
<p>For both options, you will need to ensure that <code>enable_metrics</code> is
|
|||
|
set to <code>True</code>.</p>
|
|||
|
</li>
|
|||
|
<li>
|
|||
|
<p>Restart Synapse.</p>
|
|||
|
</li>
|
|||
|
<li>
|
|||
|
<p>Add a Prometheus target for Synapse.</p>
|
|||
|
<p>It needs to set the <code>metrics_path</code> to a non-default value (under
|
|||
|
<code>scrape_configs</code>):</p>
|
|||
|
<pre><code class="language-yaml"> - job_name: "synapse"
|
|||
|
scrape_interval: 15s
|
|||
|
metrics_path: "/_synapse/metrics"
|

|
static_configs:
|
|||
|
- targets: ["my.server.here:port"]
|

|
|||
|
<p>where <code>my.server.here</code> is the IP address of Synapse, and <code>port</code> is
|
|||
|
the listener port configured with the <code>metrics</code> resource.</p>
|

<h2 id="monitoring-workers"><a class="header" href="#monitoring-workers">Monitoring workers</a></h2>
|
|||
|
<p>To monitor a Synapse installation using <a href="workers.html">workers</a>,
|
|||
|
every worker needs to be monitored independently, in addition to
|
|||
|
the main homeserver process. This is because workers don't send
|
|||
|
their metrics to the main homeserver process, but expose them
|
|||
|
directly (if they are configured to do so).</p>
|
|||
|
<p>To allow collecting metrics from a worker, you need to add a
|
|||
|
<code>metrics</code> listener to its configuration, by adding the following
|
|||
|
under <code>worker_listeners</code>:</p>
|
|||
|
<pre><code class="language-yaml"> - type: metrics
|
|||
|
bind_address: ''
|
|||
|
port: 9101
|
|||
|
</code></pre>
|
|||
|
<p>The <code>bind_address</code> and <code>port</code> parameters should be set so that
|
|||
|
the resulting listener can be reached by prometheus, and they
|
|||
|
don't clash with an existing worker.
|
|||
|
With this example, the worker's metrics would then be available
|
|||
|
on <code>http://127.0.0.1:9101</code>.</p>
|
|||
|
<p>Example Prometheus target for Synapse with workers:</p>
|
|||
|
<pre><code class="language-yaml"> - job_name: "synapse"
|
|||
|
scrape_interval: 15s
|
|||
|
metrics_path: "/_synapse/metrics"
|
|||
|
static_configs:
|
|||
|
- targets: ["my.server.here:port"]
|
|||
|
labels:
|
|||
|
instance: "my.server"
|
|||
|

HTTP requests.</p>

|
<p>At the same time, the corresponding <code>*:total</code> metrics are being renamed,

<h2 id="run-the-linters"><a class="header" href="#run-the-linters">Run the linters.</a></h2>
|

|
<p>The linters look at your code and do two things:</p>
|

|
<ul>
|
|||
|
<li>ensure that your code follows the coding style adopted by the project;</li>
|
|||
|
<li>catch a number of errors in your code.</li>
|
|||
|
</ul>
|
|||
|
<p>They're pretty fast, don't hesitate!</p>
|
|||
|
<pre><code class="language-sh">source ./env/bin/activate

</code></pre>
|
|||
|
<p>Note that this script <em>will modify your files</em> to fix styling errors.
|

|
Make sure that you have saved all your files.</p>
|
|||
|
<p>If you wish to restrict the linters to only the files changed since the last commit
|

|
(much faster!), you can instead run:</p>
|

<pre><code class="language-sh">source ./env/bin/activate

./scripts-dev/lint.sh -d
|

<p>The unit tests run parts of Synapse, including your changes, to see if anything

|
|||
|
<pre><code class="language-sh">source ./env/bin/activate

|
|||
|
</code></pre>
|
|||
|
<p>If you wish to only run <em>some</em> unit tests, you may specify
|

|
another module instead of <code>tests</code> - or a test class or a method:</p>
|
|||
|
<pre><code class="language-sh">source ./env/bin/activate

<p>If your tests fail, you may wish to look at the logs (the default log level is <code>ERROR</code>):</p>
|
|||
|
<pre><code class="language-sh">less _trial_temp/test.log
|
|||
|
</code></pre>
|
|||
|
<p>To increase the log level for the tests, set <code>SYNAPSE_TEST_LOG_LEVEL</code>:</p>

|

|
<p>The integration tests are a more comprehensive suite of tests. They
|
|||
|
run a full version of Synapse, including your changes, to check if
|
|||
|
anything was broken. They are slower than the unit tests but will
|
|||
|
typically catch more errors.</p>
|
|||
|
<p>The following command will let you run the integration test with the most common

|
configuration:</p>
|

<pre><code class="language-sh">$ docker run --rm -it -v /path/where/you/have/cloned/the/repository\:/src:ro -v /path/to/where/you/want/logs\:/logs matrixdotorg/sytest-synapse:buster

|
|||
|
<p><a href="https://github.com/matrix-org/complement">Complement</a> is a suite of black box tests that can be run on any homeserver implementation. It can also be thought of as end-to-end (e2e) tests.</p>
|
|||
|
<p>It's often nice to develop on Synapse and write Complement tests at the same time.
|
|||
|
Here is how to run your local Synapse checkout against your local Complement checkout.</p>
|
|||
|
<p>(checkout <a href="https://github.com/matrix-org/complement"><code>complement</code></a> alongside your <code>synapse</code> checkout)</p>
|
|||
|
<pre><code class="language-sh">COMPLEMENT_DIR=../complement ./scripts-dev/complement.sh
|
|||
|
</code></pre>
|
|||
|
<p>To run a specific test file, you can pass the test name at the end of the command. The name passed comes from the naming structure in your Complement tests. If you're unsure of the name, you can do a full run and copy it from the test output:</p>
|
|||
|
<pre><code class="language-sh">COMPLEMENT_DIR=../complement ./scripts-dev/complement.sh TestBackfillingHistory
|
|||
|
</code></pre>
|
|||
|
<p>To run a specific test, you can specify the whole name structure:</p>
|
|||
|
<pre><code class="language-sh">COMPLEMENT_DIR=../complement ./scripts-dev/complement.sh TestBackfillingHistory/parallel/Backfilled_historical_events_resolve_with_proper_state_in_correct_order

|
|||
|
<p>If you're curious what the database looks like after you run some tests, here are some steps to get you going in Synapse:</p>
|
|||
|
<ol>
|
|||
|
<li>In your Complement test comment out <code>defer deployment.Destroy(t)</code> and replace with <code>defer time.Sleep(2 * time.Hour)</code> to keep the homeserver running after the tests complete</li>
|
|||
|
<li>Start the Complement tests</li>
|
|||
|
<li>Find the name of the container, <code>docker ps -f name=complement_</code> (this will filter for just the Compelement related Docker containers)</li>
|
|||
|
<li>Access the container replacing the name with what you found in the previous step: <code>docker exec -it complement_1_hs_with_application_service.hs1_2 /bin/bash</code></li>
|
|||
|
<li>Install sqlite (database driver), <code>apt-get update && apt-get install -y sqlite3</code></li>
|
|||
|
<li>Then run <code>sqlite3</code> and open the database <code>.open /conf/homeserver.db</code> (this db path comes from the Synapse homeserver.yaml)</li>
|
|||
|
</ol>

|
|||
|
<p>Once you're happy with your patch, it's time to prepare a Pull Request.</p>
|
|||
|
<p>To prepare a Pull Request, please:</p>
|
|||
|
<ol>
|
|||
|
<li>verify that <a href="development/contributing_guide.html#test-test-test">all the tests pass</a>, including the coding style;</li>
|
|||
|
<li><a href="development/contributing_guide.html#sign-off">sign off</a> your contribution;</li>

|

|
<li>add a <a href="development/contributing_guide.html#changelog">changelog entry</a> and push it to your Pull Request;</li>
|
|||
|
<li>for most contributors, that's all - however, if you are a member of the organization <code>matrix-org</code>, on GitHub, please request a review from <code>matrix.org / Synapse Core</code>.</li>
|
|||
|
<li>if you need to update your PR, please avoid rebasing and just add new commits to your branch.</li>
|
|||
|
</ol>
|
|||
|
<h2 id="changelog"><a class="header" href="#changelog">Changelog</a></h2>
|
|||
|
<p>All changes, even minor ones, need a corresponding changelog / newsfragment
|
|||
|
entry. These are managed by <a href="https://github.com/hawkowl/towncrier">Towncrier</a>.</p>
|
|||
|
<p>To create a changelog entry, make a new file in the <code>changelog.d</code> directory named
|
|||
|
in the format of <code>PRnumber.type</code>. The type can be one of the following:</p>
|
|||
|
<ul>
|
|||
|
<li><code>feature</code></li>
|
|||
|
<li><code>bugfix</code></li>
|
|||
|
<li><code>docker</code> (for updates to the Docker image)</li>
|
|||
|
<li><code>doc</code> (for updates to the documentation)</li>
|
|||
|
<li><code>removal</code> (also used for deprecations)</li>
|
|||
|
<li><code>misc</code> (for internal-only changes)</li>
|
|||
|
</ul>
|
|||
|
<p>This file will become part of our <a href="https://github.com/matrix-org/synapse/blob/master/CHANGES.md">changelog</a> at the next
|
|||
|
release, so the content of the file should be a short description of your
|
|||
|
change in the same style as the rest of the changelog. The file can contain Markdown
|
|||
|
formatting, and should end with a full stop (.) or an exclamation mark (!) for
|
|||
|
consistency.</p>
|
|||
|
<p>Adding credits to the changelog is encouraged, we value your
|
|||
|
contributions and would like to have you shouted out in the release notes!</p>
|
|||
|
<p>For example, a fix in PR #1234 would have its changelog entry in
|
|||
|
<code>changelog.d/1234.bugfix</code>, and contain content like:</p>
|
|||
|
<blockquote>
|
|||
|
<p>The security levels of Florbs are now validated when received
|
|||
|
via the <code>/federation/florb</code> endpoint. Contributed by Jane Matrix.</p>
|
|||
|
</blockquote>
|
|||
|
<p>If there are multiple pull requests involved in a single bugfix/feature/etc,
|
|||
|
then the content for each <code>changelog.d</code> file should be the same. Towncrier will
|
|||
|
merge the matching files together into a single changelog entry when we come to
|
|||
|
release.</p>
|
|||
|
<h3 id="how-do-i-know-what-to-call-the-changelog-file-before-i-create-the-pr"><a class="header" href="#how-do-i-know-what-to-call-the-changelog-file-before-i-create-the-pr">How do I know what to call the changelog file before I create the PR?</a></h3>
|
|||
|
<p>Obviously, you don't know if you should call your newsfile
|
|||
|
<code>1234.bugfix</code> or <code>5678.bugfix</code> until you create the PR, which leads to a
|
|||
|
chicken-and-egg problem.</p>
|
|||
|
<p>There are two options for solving this:</p>
|
|||
|
<ol>
|
|||
|
<li>
|
|||
|
<p>Open the PR without a changelog file, see what number you got, and <em>then</em>
|
|||
|
add the changelog file to your branch (see <a href="development/contributing_guide.html#updating-your-pull-request">Updating your pull
|
|||
|
request</a>), or:</p>
|
|||
|
</li>
|
|||
|
<li>
|
|||
|
<p>Look at the <a href="https://github.com/matrix-org/synapse/issues?q=">list of all
|
|||
|
issues/PRs</a>, add one to the
|
|||
|
highest number you see, and quickly open the PR before somebody else claims
|
|||
|
your number.</p>
|
|||
|

|
|||
|

|
|||
|
</li>
|
|||
|
</ol>
|
|||
|
<p>Sorry, we know it's a bit fiddly, but it's <em>really</em> helpful for us when we come
|
|||
|
to put together a release!</p>
|
|||
|
<h3 id="debian-changelog"><a class="header" href="#debian-changelog">Debian changelog</a></h3>
|
|||
|
<p>Changes which affect the debian packaging files (in <code>debian</code>) are an
|
|||
|
exception to the rule that all changes require a <code>changelog.d</code> file.</p>
|
|||
|
<p>In this case, you will need to add an entry to the debian changelog for the
|
|||
|
next release. For this, run the following command:</p>
|
|||
|
<pre><code>dch
|
|||
|
</code></pre>
|
|||
|
<p>This will make up a new version number (if there isn't already an unreleased
|
|||
|
version in flight), and open an editor where you can add a new changelog entry.
|
|||
|
(Our release process will ensure that the version number and maintainer name is
|
|||
|
corrected for the release.)</p>
|
|||
|
<p>If your change affects both the debian packaging <em>and</em> files outside the debian
|
|||
|
directory, you will need both a regular newsfragment <em>and</em> an entry in the
|
|||
|
debian changelog. (Though typically such changes should be submitted as two
|
|||
|
separate pull requests.)</p>

<p>That's it! Matrix is a very open and collaborative project as you might expect
|
|||
|
given our obsession with open communication. If we're going to successfully
|
|||
|
matrix together all the fragmented communication technologies out there we are
|
|||
|
reliant on contributions and collaboration from the community to do so. So
|
|||

<h2 id="formatting-tools"><a class="header" href="#formatting-tools">Formatting tools</a></h2>
|
|||
|
<p>The Synapse codebase uses a number of code formatting tools in order to
|
|||
|
quickly and automatically check for formatting (and sometimes logical)
|
|||
|
errors in code.</p>
|
|||
|
<p>The necessary tools are detailed below.</p>
|
|||
|
<p>First install them with:</p>
|
|||
|
<pre><code>pip install -e ".[lint,mypy]"
|
|||
|
</code></pre>
|
|||
|
<ul>
|
|||
|
<li>
|
|||
|
<p><strong>black</strong></p>
|
|||
|
<p>The Synapse codebase uses <a href="https://pypi.org/project/black/">black</a>
|
|||
|
as an opinionated code formatter, ensuring all comitted code is
|
|||
|
properly formatted.</p>
|
|||
|
<p>Have <code>black</code> auto-format your code (it shouldn't change any
|
|||
|
functionality) with:</p>
|
|||
|
<pre><code>black . --exclude="\.tox|build|env"
|
|||
|
</code></pre>
|
|||
|
</li>
|
|||
|
<li>
|
|||
|
<p><strong>flake8</strong></p>
|
|||
|
<p><code>flake8</code> is a code checking tool. We require code to pass <code>flake8</code>
|
|||
|
before being merged into the codebase.</p>
|
|||
|
<p>Check all application and test code with:</p>
|
|||
|
<pre><code>flake8 synapse tests
|
|||
|
</code></pre>
|
|||
|
</li>
|
|||
|
<li>
|
|||
|
<p><strong>isort</strong></p>
|
|||
|
<p><code>isort</code> ensures imports are nicely formatted, and can suggest and
|
|||
|
auto-fix issues such as double-importing.</p>
|
|||
|
<p>Auto-fix imports with:</p>
|
|||
|
<pre><code>isort -rc synapse tests
|
|||
|
</code></pre>
|
|||
|
<p><code>-rc</code> means to recursively search the given directories.</p>
|
|||
|
</li>
|
|||
|
</ul>
|
|||
|
<p>It's worth noting that modern IDEs and text editors can run these tools
|
|||
|
automatically on save. It may be worth looking into whether this
|
|||
|
functionality is supported in your editor for a more convenient
|
|||
|
development workflow. It is not, however, recommended to run <code>flake8</code> on
|
|||
|
save as it takes a while and is very resource intensive.</p>

<h2 id="general-rules"><a class="header" href="#general-rules">General rules</a></h2>
|
|||
|
<ul>
|
|||
|
<li><strong>Naming</strong>:
|
|||
|
<ul>
|
|||
|
<li>Use camel case for class and type names</li>
|
|||
|
<li>Use underscores for functions and variables.</li>
|
|||
|
</ul>
|
|||
|
</li>
|
|||
|
<li><strong>Docstrings</strong>: should follow the <a href="https://google.github.io/styleguide/pyguide.html#38-comments-and-docstrings">google code
|
|||
|
style</a>.
|
|||
|
See the
|
|||
|
<a href="http://sphinxcontrib-napoleon.readthedocs.io/en/latest/example_google.html">examples</a>
|
|||
|
in the sphinx documentation.</li>
|
|||
|
<li><strong>Imports</strong>:
|
|||
|
<ul>
|
|||
|
<li>
|
|||
|
<p>Imports should be sorted by <code>isort</code> as described above.</p>
|
|||
|
</li>
|
|||
|
<li>
|
|||
|
<p>Prefer to import classes and functions rather than packages or
|
|||
|
modules.</p>
|
|||
|
<p>Example:</p>
|
|||
|
<pre><code>from synapse.types import UserID
|
|||
|
...
|
|||
|
user_id = UserID(local, server)
|
|||
|
</code></pre>
|
|||
|
<p>is preferred over:</p>
|
|||
|
<pre><code>from synapse import types
|
|||
|
...
|
|||
|
user_id = types.UserID(local, server)
|
|||
|
</code></pre>
|
|||
|
<p>(or any other variant).</p>
|
|||
|
<p>This goes against the advice in the Google style guide, but it
|
|||
|
means that errors in the name are caught early (at import time).</p>
|
|||
|
</li>
|
|||
|
<li>
|
|||
|
<p>Avoid wildcard imports (<code>from synapse.types import *</code>) and
|
|||
|
relative imports (<code>from .types import UserID</code>).</p>

<h2 id="configuration-file-format"><a class="header" href="#configuration-file-format">Configuration file format</a></h2>
|
|||
|
<p>The <a href="./sample_config.yaml">sample configuration file</a> acts as a
|
|||
|
reference to Synapse's configuration options for server administrators.
|
|||
|
Remember that many readers will be unfamiliar with YAML and server
|
|||
|
administration in general, so that it is important that the file be as
|
|||
|
easy to understand as possible, which includes following a consistent
|
|||
|
format.</p>
|
|||
|
<p>Some guidelines follow:</p>
|
|||
|
<ul>
|
|||
|
<li>
|
|||
|
<p>Sections should be separated with a heading consisting of a single
|
|||
|
line prefixed and suffixed with <code>##</code>. There should be <strong>two</strong> blank
|
|||
|
lines before the section header, and <strong>one</strong> after.</p>
|
|||
|
</li>
|
|||
|
<li>
|
|||
|
<p>Each option should be listed in the file with the following format:</p>
|
|||
|
<ul>
|
|||
|
<li>
|
|||
|
<p>A comment describing the setting. Each line of this comment
|
|||
|
should be prefixed with a hash (<code>#</code>) and a space.</p>
|
|||
|
<p>The comment should describe the default behaviour (ie, what
|
|||
|
happens if the setting is omitted), as well as what the effect
|
|||
|
will be if the setting is changed.</p>
|
|||
|
<p>Often, the comment end with something like "uncomment the
|
|||
|
following to <do action>".</p>
|
|||
|
</li>
|
|||
|
<li>
|
|||
|
<p>A line consisting of only <code>#</code>.</p>
|
|||
|
</li>
|
|||
|
<li>
|
|||
|
<p>A commented-out example setting, prefixed with only <code>#</code>.</p>
|
|||
|
<p>For boolean (on/off) options, convention is that this example
|
|||
|
should be the <em>opposite</em> to the default (so the comment will end
|
|||
|
with "Uncomment the following to enable [or disable]
|
|||
|
<feature>." For other options, the example should give some
|
|||
|
non-default value which is likely to be useful to the reader.</p>
|
|||
|
</li>
|
|||
|
</ul>
|
|||
|
</li>
|
|||
|
<li>
|
|||
|
<p>There should be a blank line between each option.</p>
|
|||
|
</li>
|
|||
|
<li>
|
|||
|
<p>Where several settings are grouped into a single dict, <em>avoid</em> the
|
|||
|
convention where the whole block is commented out, resulting in
|
|||
|
comment lines starting <code># #</code>, as this is hard to read and confusing
|
|||
|
to edit. Instead, leave the top-level config option uncommented, and
|
|||
|
follow the conventions above for sub-options. Ensure that your code
|
|||
|
correctly handles the top-level option being set to <code>None</code> (as it
|
|||
|
will be if no sub-options are enabled).</p>
|
|||
|
</li>
|
|||
|
<li>
|
|||
|
<p>Lines should be wrapped at 80 characters.</p>
|
|||
|
</li>
|
|||
|
<li>
|
|||
|
<p>Use two-space indents.</p>
|
|||
|
</li>
|
|||
|
<li>
|
|||
|
<p><code>true</code> and <code>false</code> are spelt thus (as opposed to <code>True</code>, etc.)</p>
|
|||
|
</li>
|
|||
|
<li>
|
|||
|
<p>Use single quotes (<code>'</code>) rather than double-quotes (<code>"</code>) or backticks
|
|||
|
(<code>`</code>) to refer to configuration options.</p>
|
|||
|
</li>
|
|||
|
</ul>
|
|||
|
<p>Example:</p>
|
|||
|
<pre><code>## Frobnication ##
|
|||
|
|
|||
|
# The frobnicator will ensure that all requests are fully frobnicated.

# To enable it, uncomment the following.
|
|||
|
#
|
|||
|
#frobnicator_enabled: true
|
|||
|
|
|||
|
# By default, the frobnicator will frobnicate with the default frobber.
|
|||
|
# The following will make it use an alternative frobber.
|
|||
|
#
|
|||
|
#frobincator_frobber: special_frobber
|
|||
|
|
|||
|
# Settings for the frobber
|
|||
|
#
|
|||
|
frobber:
|
|||
|
# frobbing speed. Defaults to 1.
|
|||
|
#
|
|||
|
#speed: 10
|
|||
|
|
|||
|
# frobbing distance. Defaults to 1000.
|
|||
|
#
|
|||
|
#distance: 100
|
|||
|
</code></pre>
|
|||
|
<p>Note that the sample configuration is generated from the synapse code
|
|||
|
and is maintained by a script, <code>scripts-dev/generate_sample_config</code>.
|
|||
|
Making sure that the output from this script matches the desired format
|
|||
|
is left as an exercise for the reader!</p>

<h2 id="on-keeping-the-commit-history-clean"><a class="header" href="#on-keeping-the-commit-history-clean">On keeping the commit history clean</a></h2>
|
|||
|
<p>In an ideal world, our git commit history would be a linear progression of
|
|||
|
commits each of which contains a single change building on what came
|
|||
|
before. Here, by way of an arbitrary example, is the top of <code>git log --graph b2dba0607</code>:</p>
|
|||
|
<img src="development/img/git/clean.png" alt="clean git graph" width="500px">
|
|||
|
<p>Note how the commit comment explains clearly what is changing and why. Also
|
|||
|
note the <em>absence</em> of merge commits, as well as the absence of commits called
|
|||
|
things like (to pick a few culprits):
|
|||
|
<a href="https://github.com/matrix-org/synapse/commit/84691da6c">“pep8”</a>, <a href="https://github.com/matrix-org/synapse/commit/474810d9d">“fix broken
|
|||
|
test”</a>,
|
|||
|
<a href="https://github.com/matrix-org/synapse/commit/c9d72e457">“oops”</a>,
|
|||
|
<a href="https://github.com/matrix-org/synapse/commit/836358823">“typo”</a>, or <a href="https://github.com/matrix-org/synapse/commit/707374d5d">“Who's
|
|||
|
the president?”</a>.</p>
|
|||
|
<p>There are a number of reasons why keeping a clean commit history is a good
|
|||
|
thing:</p>
|
|||
|
<ul>
|
|||
|
<li>
|
|||
|
<p>From time to time, after a change lands, it turns out to be necessary to
|
|||
|
revert it, or to backport it to a release branch. Those operations are
|
|||
|
<em>much</em> easier when the change is contained in a single commit.</p>
|
|||
|
</li>
|
|||
|
<li>
|
|||
|
<p>Similarly, it's much easier to answer questions like “is the fix for
|
|||
|
<code>/publicRooms</code> on the release branch?” if that change consists of a single
|
|||
|
commit.</p>
|
|||
|
</li>
|
|||
|
<li>
|
|||
|
<p>Likewise: “what has changed on this branch in the last week?” is much
|
|||
|
clearer without merges and “pep8” commits everywhere.</p>
|
|||
|
</li>
|
|||
|
<li>
|
|||
|
<p>Sometimes we need to figure out where a bug got introduced, or some
|
|||
|
behaviour changed. One way of doing that is with <code>git bisect</code>: pick an
|
|||
|
arbitrary commit between the known good point and the known bad point, and
|
|||
|
see how the code behaves. However, that strategy fails if the commit you
|
|||
|
chose is the middle of someone's epic branch in which they broke the world
|
|||
|
before putting it back together again.</p>
|
|||
|
</li>
|
|||
|
</ul>
|
|||
|
<p>One counterargument is that it is sometimes useful to see how a PR evolved as
|
|||
|
it went through review cycles. This is true, but that information is always
|
|||
|
available via the GitHub UI (or via the little-known <a href="https://help.github.com/en/github/collaborating-with-issues-and-pull-requests/checking-out-pull-requests-locally">refs/pull
|
|||
|
namespace</a>).</p>
|
|||
|
<p>Of course, in reality, things are more complicated than that. We have release
|
|||
|
branches as well as <code>develop</code> and <code>master</code>, and we deliberately merge changes
|
|||
|
between them. Bugs often slip through and have to be fixed later. That's all
|
|||
|
fine: this not a cast-iron rule which must be obeyed, but an ideal to aim
|
|||
|
towards.</p>
|
|||
|
<h2 id="merges-squashes-rebases-wtf"><a class="header" href="#merges-squashes-rebases-wtf">Merges, squashes, rebases: wtf?</a></h2>
|
|||
|
<p>Ok, so that's what we'd like to achieve. How do we achieve it?</p>
|
|||
|
<p>The TL;DR is: when you come to merge a pull request, you <em>probably</em> want to
|
|||
|
“squash and merge”:</p>
|
|||
|
<p><img src="development/img/git/squash.png" alt="squash and merge" />.</p>
|
|||
|
<p>(This applies whether you are merging your own PR, or that of another
|
|||
|
contributor.)</p>
|
|||
|
<p>“Squash and merge”<sup id="a1"><a href="development/git.html#f1">1</a></sup> takes all of the changes in the
|
|||
|
PR, and bundles them into a single commit. GitHub gives you the opportunity to
|
|||
|
edit the commit message before you confirm, and normally you should do so,
|
|||
|
because the default will be useless (again: <code>* woops typo</code> is not a useful
|
|||
|
thing to keep in the historical record).</p>
|
|||
|
<p>The main problem with this approach comes when you have a series of pull
|
|||
|
requests which build on top of one another: as soon as you squash-merge the
|
|||
|
first PR, you'll end up with a stack of conflicts to resolve in all of the
|
|||
|
others. In general, it's best to avoid this situation in the first place by
|
|||
|
trying not to have multiple related PRs in flight at the same time. Still,
|
|||
|
sometimes that's not possible and doing a regular merge is the lesser evil.</p>
|
|||
|
<p>Another occasion in which a regular merge makes more sense is a PR where you've
|
|||
|
deliberately created a series of commits each of which makes sense in its own
|
|||
|
right. For example: <a href="https://github.com/matrix-org/synapse/pull/6837">a PR which gradually propagates a refactoring operation
|
|||
|
through the codebase</a>, or <a href="https://github.com/matrix-org/synapse/pull/5987">a
|
|||
|
PR which is the culmination of several other
|
|||
|
PRs</a>. In this case the ability
|
|||
|
to figure out when a particular change/bug was introduced could be very useful.</p>
|
|||
|
<p>Ultimately: <strong>this is not a hard-and-fast-rule</strong>. If in doubt, ask yourself “do
|
|||
|
each of the commits I am about to merge make sense in their own right”, but
|
|||
|
remember that we're just doing our best to balance “keeping the commit history
|
|||
|
clean” with other factors.</p>

<h2 id="git-branching-model"><a class="header" href="#git-branching-model">Git branching model</a></h2>
|
|||
|
<p>A <a href="https://nvie.com/posts/a-successful-git-branching-model/">lot</a>
|
|||
|
<a href="http://scottchacon.com/2011/08/31/github-flow.html">of</a>
|
|||
|
<a href="https://www.endoflineblog.com/gitflow-considered-harmful">words</a> have been
|
|||
|
written in the past about git branching models (no really, <a href="https://martinfowler.com/articles/branching-patterns.html">a
|
|||
|
lot</a>). I tend to
|
|||
|
think the whole thing is overblown. Fundamentally, it's not that
|
|||
|
complicated. Here's how we do it.</p>
|
|||
|
<p>Let's start with a picture:</p>
|
|||
|
<p><img src="development/img/git/branches.jpg" alt="branching model" /></p>
|
|||
|
<p>It looks complicated, but it's really not. There's one basic rule: <em>anyone</em> is
|
|||
|
free to merge from <em>any</em> more-stable branch to <em>any</em> less-stable branch at
|
|||
|
<em>any</em> time<sup id="a2"><a href="development/git.html#f2">2</a></sup>. (The principle behind this is that if a
|
|||
|
change is good enough for the more-stable branch, then it's also good enough go
|
|||
|
put in a less-stable branch.)</p>
|
|||
|
<p>Meanwhile, merging (or squashing, as per the above) from a less-stable to a
|
|||
|
more-stable branch is a deliberate action in which you want to publish a change
|
|||
|
or a set of changes to (some subset of) the world: for example, this happens
|
|||
|
when a PR is landed, or as part of our release process.</p>
|
|||
|
<p>So, what counts as a more- or less-stable branch? A little reflection will show
|
|||
|
that our active branches are ordered thus, from more-stable to less-stable:</p>
|
|||
|
<ul>
|
|||
|
<li><code>master</code> (tracks our last release).</li>
|
|||
|
<li><code>release-vX.Y</code> (the branch where we prepare the next release)<sup
|
|||
|
id="a3"><a href="development/git.html#f3">3</a></sup>.</li>
|
|||
|
<li>PR branches which are targeting the release.</li>
|
|||
|
<li><code>develop</code> (our "mainline" branch containing our bleeding-edge).</li>
|
|||
|
<li>regular PR branches.</li>
|
|||
|
</ul>
|
|||
|
<p>The corollary is: if you have a bugfix that needs to land in both
|
|||
|
<code>release-vX.Y</code> <em>and</em> <code>develop</code>, then you should base your PR on
|
|||
|
<code>release-vX.Y</code>, get it merged there, and then merge from <code>release-vX.Y</code> to
|
|||
|
<code>develop</code>. (If a fix lands in <code>develop</code> and we later need it in a
|
|||
|
release-branch, we can of course cherry-pick it, but landing it in the release
|
|||
|
branch first helps reduce the chance of annoying conflicts.)</p>

|
|||
|
<p>OpenTracing is a semi-standard being adopted by a number of distributed
|
|||
|
tracing platforms. It is a common api for facilitating vendor-agnostic
|
|||
|
tracing instrumentation. That is, we can use the OpenTracing api and
|
|||
|
select one of a number of tracer implementations to do the heavy lifting
|
|||
|
in the background. Our current selected implementation is Jaeger.</p>
|
|||
|
<p>OpenTracing is a tool which gives an insight into the causal
|
|||
|
relationship of work done in and between servers. The servers each track
|
|||
|
events and report them to a centralised server - in Synapse's case:
|
|||
|
Jaeger. The basic unit used to represent events is the span. The span
|
|||
|
roughly represents a single piece of work that was done and the time at
|
|||
|
which it occurred. A span can have child spans, meaning that the work of
|
|||
|
the child had to be completed for the parent span to complete, or it can
|
|||
|
have follow-on spans which represent work that is undertaken as a result
|
|||
|
of the parent but is not depended on by the parent to in order to
|
|||
|
finish.</p>
|
|||
|
<p>Since this is undertaken in a distributed environment a request to
|
|||
|
another server, such as an RPC or a simple GET, can be considered a span
|
|||
|
(a unit or work) for the local server. This causal link is what
|
|||
|
OpenTracing aims to capture and visualise. In order to do this metadata
|
|||
|
about the local server's span, i.e the 'span context', needs to be
|
|||
|
included with the request to the remote.</p>
|
|||
|
<p>It is up to the remote server to decide what it does with the spans it
|
|||
|
creates. This is called the sampling policy and it can be configured
|
|||
|
through Jaeger's settings.</p>

<h2 id="homeserver-whitelisting"><a class="header" href="#homeserver-whitelisting">Homeserver whitelisting</a></h2>

<p>Though it's mostly safe to send and receive span contexts to and from

untrusted users since span contexts are usually opaque ids it can lead

to two problems, namely:</p>
|

|
<ul>
|

|
<li>If the span context is marked as sampled by the sending homeserver
|
|||
|
the receiver will sample it. Therefore two homeservers with wildly
|
|||
|
different sampling policies could incur higher sampling counts than
|
|||
|
intended.</li>
|
|||
|
<li>Sending servers can attach arbitrary data to spans, known as
|
|||
|
'baggage'. For safety this has been disabled in Synapse but that
|

|
doesn't prevent another server sending you baggage which will be
|

logged to OpenTracing's logs.</li>

<div id="chapter_begin" style="break-before: page; page-break-before: always;"></div><h1 id="synapse-database-schema-files"><a class="header" href="#synapse-database-schema-files">Synapse database schema files</a></h1>
|
|||
|
<p>Synapse's database schema is stored in the <code>synapse.storage.schema</code> module.</p>
|
|||
|
<h2 id="logical-databases"><a class="header" href="#logical-databases">Logical databases</a></h2>
|
|||
|
<p>Synapse supports splitting its datastore across multiple physical databases (which can
|
|||
|
be useful for large installations), and the schema files are therefore split according
|
|||
|
to the logical database they apply to.</p>
|
|||
|
<p>At the time of writing, the following "logical" databases are supported:</p>
|
|||
|
<ul>
|
|||
|
<li><code>state</code> - used to store Matrix room state (more specifically, <code>state_groups</code>,
|
|||
|
their relationships and contents).</li>
|
|||
|
<li><code>main</code> - stores everything else.</li>
|
|||
|
</ul>
|
|||
|
<p>Additionally, the <code>common</code> directory contains schema files for tables which must be
|
|||
|
present on <em>all</em> physical databases.</p>
|
|||
|
<h2 id="synapse-schema-versions"><a class="header" href="#synapse-schema-versions">Synapse schema versions</a></h2>
|
|||
|
<p>Synapse manages its database schema via "schema versions". These are mainly used to
|
|||
|
help avoid confusion if the Synapse codebase is rolled back after the database is
|
|||
|
updated. They work as follows:</p>
|
|||
|
<ul>
|
|||
|
<li>
|
|||
|
<p>The Synapse codebase defines a constant <code>synapse.storage.schema.SCHEMA_VERSION</code>
|
|||
|
which represents the expectations made about the database by that version. For
|
|||
|
example, as of Synapse v1.36, this is <code>59</code>.</p>
|
|||
|
</li>
|
|||
|
<li>
|
|||
|
<p>The database stores a "compatibility version" in
|
|||
|
<code>schema_compat_version.compat_version</code> which defines the <code>SCHEMA_VERSION</code> of the
|
|||
|
oldest version of Synapse which will work with the database. On startup, if
|
|||
|
<code>compat_version</code> is found to be newer than <code>SCHEMA_VERSION</code>, Synapse will refuse to
|
|||
|
start.</p>
|
|||
|
<p>Synapse automatically updates this field from
|
|||
|
<code>synapse.storage.schema.SCHEMA_COMPAT_VERSION</code>.</p>
|
|||
|
</li>
|
|||
|
<li>
|
|||
|
<p>Whenever a backwards-incompatible change is made to the database format (normally
|
|||
|
via a <code>delta</code> file), <code>synapse.storage.schema.SCHEMA_COMPAT_VERSION</code> is also updated
|
|||
|
so that administrators can not accidentally roll back to a too-old version of Synapse.</p>
|
|||
|
</li>
|
|||
|
</ul>
|
|||
|
<p>Generally, the goal is to maintain compatibility with at least one or two previous
|
|||
|
releases of Synapse, so any substantial change tends to require multiple releases and a
|
|||
|
bit of forward-planning to get right.</p>
|
|||
|
<p>As a worked example: we want to remove the <code>room_stats_historical</code> table. Here is how it
|
|||
|
might pan out.</p>
|
|||
|
<ol>
|
|||
|
<li>
|
|||
|
<p>Replace any code that <em>reads</em> from <code>room_stats_historical</code> with alternative
|
|||
|
implementations, but keep writing to it in case of rollback to an earlier version.
|
|||
|
Also, increase <code>synapse.storage.schema.SCHEMA_VERSION</code>. In this
|
|||
|
instance, there is no existing code which reads from <code>room_stats_historical</code>, so
|
|||
|
our starting point is:</p>
|
|||
|
<p>v1.36.0: <code>SCHEMA_VERSION=59</code>, <code>SCHEMA_COMPAT_VERSION=59</code></p>
|
|||
|
</li>
|
|||
|
<li>
|
|||
|
<p>Next (say in Synapse v1.37.0): remove the code that <em>writes</em> to
|
|||
|
<code>room_stats_historical</code>, but don’t yet remove the table in case of rollback to
|
|||
|
v1.36.0. Again, we increase <code>synapse.storage.schema.SCHEMA_VERSION</code>, but
|
|||
|
because we have not broken compatibility with v1.36, we do not yet update
|
|||
|
<code>SCHEMA_COMPAT_VERSION</code>. We now have:</p>
|
|||
|
<p>v1.37.0: <code>SCHEMA_VERSION=60</code>, <code>SCHEMA_COMPAT_VERSION=59</code>.</p>
|
|||
|
</li>
|
|||
|
<li>
|
|||
|
<p>Later (say in Synapse v1.38.0): we can remove the table altogether. This will
|
|||
|
break compatibility with v1.36.0, so we must update <code>SCHEMA_COMPAT_VERSION</code> accordingly.
|
|||
|
There is no need to update <code>synapse.storage.schema.SCHEMA_VERSION</code>, since there is no
|
|||
|
change to the Synapse codebase here. So we end up with:</p>
|
|||
|
<p>v1.38.0: <code>SCHEMA_VERSION=60</code>, <code>SCHEMA_COMPAT_VERSION=60</code>.</p>
|
|||
|
</li>
|
|||
|
</ol>
|
|||
|
<p>If in doubt about whether to update <code>SCHEMA_VERSION</code> or not, it is generally best to
|
|||
|
lean towards doing so.</p>
|
|||
|
<h2 id="full-schema-dumps"><a class="header" href="#full-schema-dumps">Full schema dumps</a></h2>
|
|||
|
<p>In the <code>full_schemas</code> directories, only the most recently-numbered snapshot is used
|
|||
|
(<code>54</code> at the time of writing). Older snapshots (eg, <code>16</code>) are present for historical
|
|||
|
reference only.</p>
|
|||
|
<h3 id="building-full-schema-dumps"><a class="header" href="#building-full-schema-dumps">Building full schema dumps</a></h3>
|
|||
|
<p>If you want to recreate these schemas, they need to be made from a database that
|
|||
|
has had all background updates run.</p>
|
|||
|
<p>To do so, use <code>scripts-dev/make_full_schema.sh</code>. This will produce new
|
|||
|
<code>full.sql.postgres</code> and <code>full.sql.sqlite</code> files.</p>
|
|||
|
<p>Ensure postgres is installed, then run:</p>
|
|||
|
<pre><code>./scripts-dev/make_full_schema.sh -p postgres_username -o output_dir/
|
|||
|
</code></pre>
|
|||
|
<p>NB at the time of writing, this script predates the split into separate <code>state</code>/<code>main</code>
|
|||
|
databases so will require updates to handle that correctly.</p>
|
|||
|
<h2 id="boolean-columns"><a class="header" href="#boolean-columns">Boolean columns</a></h2>
|
|||
|
<p>Boolean columns require special treatment, since SQLite treats booleans the
|
|||
|
same as integers.</p>
|
|||
|
<p>There are three separate aspects to this:</p>
|
|||
|
<ul>
|
|||
|
<li>
|
|||
|
<p>Any new boolean column must be added to the <code>BOOLEAN_COLUMNS</code> list in
|
|||
|
<code>scripts/synapse_port_db</code>. This tells the port script to cast the integer
|
|||
|
value from SQLite to a boolean before writing the value to the postgres
|
|||
|
database.</p>
|
|||
|
</li>
|
|||
|
<li>
|
|||
|
<p>Before SQLite 3.23, <code>TRUE</code> and <code>FALSE</code> were not recognised as constants by
|
|||
|
SQLite, and the <code>IS [NOT] TRUE</code>/<code>IS [NOT] FALSE</code> operators were not
|
|||
|
supported. This makes it necessary to avoid using <code>TRUE</code> and <code>FALSE</code>
|
|||
|
constants in SQL commands.</p>
|
|||
|
<p>For example, to insert a <code>TRUE</code> value into the database, write:</p>
|
|||
|
<pre><code class="language-python">txn.execute("INSERT INTO tbl(col) VALUES (?)", (True, ))
|
|||
|
</code></pre>
|
|||
|
</li>
|
|||
|
<li>
|
|||
|
<p>Default values for new boolean columns present a particular
|
|||
|
difficulty. Generally it is best to create separate schema files for
|
|||
|
Postgres and SQLite. For example:</p>
|
|||
|
<pre><code class="language-sql"># in 00delta.sql.postgres:
|
|||
|
ALTER TABLE tbl ADD COLUMN col BOOLEAN DEFAULT FALSE;
|
|||
|
</code></pre>
|
|||
|
<pre><code class="language-sql"># in 00delta.sql.sqlite:
|
|||
|
ALTER TABLE tbl ADD COLUMN col BOOLEAN DEFAULT 0;
|
|||
|
</code></pre>
|
|||
|
<p>Note that there is a particularly insidious failure mode here: the Postgres
|
|||
|
flavour will be accepted by SQLite 3.22, but will give a column whose
|
|||
|
default value is the <strong>string</strong> <code>"FALSE"</code> - which, when cast back to a boolean
|
|||
|
in Python, evaluates to <code>True</code>.</p>
|
|||
|
</li>
|
|||
|
</ul>
|
|||
|
<div id="chapter_begin" style="break-before: page; page-break-before: always;"></div><h1 id="log-contexts"><a class="header" href="#log-contexts">Log Contexts</a></h1>
|
|||
|
<p>To help track the processing of individual requests, synapse uses a
|
|||
|
'<code>log context</code>' to track which request it is handling at any given
|
|||
|
moment. This is done via a thread-local variable; a <code>logging.Filter</code> is
|
|||
|
then used to fish the information back out of the thread-local variable
|
|||
|
and add it to each log record.</p>
|
|||
|
<p>Logcontexts are also used for CPU and database accounting, so that we
|
|||
|
can track which requests were responsible for high CPU use or database
|
|||
|
activity.</p>
|
|||
|
<p>The <code>synapse.logging.context</code> module provides facilities for managing
|
|||
|
the current log context (as well as providing the <code>LoggingContextFilter</code>
|
|||
|
class).</p>
|
|||
|
<p>Asynchronous functions make the whole thing complicated, so this document describes
|
|||
|
how it all works, and how to write code which follows the rules.</p>
|
|||
|
<p>In this document, "awaitable" refers to any object which can be <code>await</code>ed. In the context of
|
|||
|
Synapse, that normally means either a coroutine or a Twisted
|
|||
|
<a href="https://twistedmatrix.com/documents/current/api/twisted.internet.defer.Deferred.html"><code>Deferred</code></a>.</p>
|
|||
|
<h2 id="logcontexts-without-asynchronous-code"><a class="header" href="#logcontexts-without-asynchronous-code">Logcontexts without asynchronous code</a></h2>
|
|||
|
<p>In the absence of any asynchronous voodoo, things are simple enough. As with
|
|||
|
any code of this nature, the rule is that our function should leave
|
|||
|
things as it found them:</p>
|
|||
|
<pre><code class="language-python">from synapse.logging import context # omitted from future snippets
|
|||
|
|
|||
|
def handle_request(request_id):
|
|||
|
request_context = context.LoggingContext()
|
|||
|
|
|||
|
calling_context = context.set_current_context(request_context)
|
|||
|
try:
|
|||
|
request_context.request = request_id
|
|||
|
do_request_handling()
|
|||
|
logger.debug("finished")
|
|||
|
finally:
|
|||
|
context.set_current_context(calling_context)
|
|||
|
|
|||
|
def do_request_handling():
|
|||
|
logger.debug("phew") # this will be logged against request_id
|
|||
|
</code></pre>
|
|||
|
<p>LoggingContext implements the context management methods, so the above
|
|||
|
can be written much more succinctly as:</p>
|
|||
|
<pre><code class="language-python">def handle_request(request_id):
|
|||
|
with context.LoggingContext() as request_context:
|
|||
|
request_context.request = request_id
|
|||
|
do_request_handling()
|
|||
|
logger.debug("finished")
|
|||
|
|
|||
|
def do_request_handling():
|
|||
|
logger.debug("phew")
|
|||
|
</code></pre>
|
|||
|
<h2 id="using-logcontexts-with-awaitables"><a class="header" href="#using-logcontexts-with-awaitables">Using logcontexts with awaitables</a></h2>
|
|||
|
<p>Awaitables break the linear flow of code so that there is no longer a single entry point
|
|||
|
where we should set the logcontext and a single exit point where we should remove it.</p>
|
|||
|
<p>Consider the example above, where <code>do_request_handling</code> needs to do some
|
|||
|
blocking operation, and returns an awaitable:</p>
|
|||
|
<pre><code class="language-python">async def handle_request(request_id):
|
|||
|
with context.LoggingContext() as request_context:
|
|||
|
request_context.request = request_id
|
|||
|
await do_request_handling()
|
|||
|
logger.debug("finished")
|
|||
|
</code></pre>
|
|||
|
<p>In the above flow:</p>
|
|||
|
<ul>
|
|||
|
<li>The logcontext is set</li>
|
|||
|
<li><code>do_request_handling</code> is called, and returns an awaitable</li>
|
|||
|
<li><code>handle_request</code> awaits the awaitable</li>
|
|||
|
<li>Execution of <code>handle_request</code> is suspended</li>
|
|||
|
</ul>
|
|||
|
<p>So we have stopped processing the request (and will probably go on to
|
|||
|
start processing the next), without clearing the logcontext.</p>
|
|||
|
<p>To circumvent this problem, synapse code assumes that, wherever you have
|
|||
|
an awaitable, you will want to <code>await</code> it. To that end, whereever
|
|||
|
functions return awaitables, we adopt the following conventions:</p>
|
|||
|
<p><strong>Rules for functions returning awaitables:</strong></p>
|
|||
|
<blockquote>
|
|||
|
<ul>
|
|||
|
<li>If the awaitable is already complete, the function returns with the
|
|||
|
same logcontext it started with.</li>
|
|||
|
<li>If the awaitable is incomplete, the function clears the logcontext
|
|||
|
before returning; when the awaitable completes, it restores the
|
|||
|
logcontext before running any callbacks.</li>
|
|||
|
</ul>
|
|||
|
</blockquote>
|
|||
|
<p>That sounds complicated, but actually it means a lot of code (including
|
|||
|
the example above) "just works". There are two cases:</p>
|
|||
|
<ul>
|
|||
|
<li>
|
|||
|
<p>If <code>do_request_handling</code> returns a completed awaitable, then the
|
|||
|
logcontext will still be in place. In this case, execution will
|
|||
|
continue immediately after the <code>await</code>; the "finished" line will
|
|||
|
be logged against the right context, and the <code>with</code> block restores
|
|||
|
the original context before we return to the caller.</p>
|
|||
|
</li>
|
|||
|
<li>
|
|||
|
<p>If the returned awaitable is incomplete, <code>do_request_handling</code> clears
|
|||
|
the logcontext before returning. The logcontext is therefore clear
|
|||
|
when <code>handle_request</code> <code>await</code>s the awaitable.</p>
|
|||
|
<p>Once <code>do_request_handling</code>'s awaitable completes, it will reinstate
|
|||
|
the logcontext, before running the second half of <code>handle_request</code>,
|
|||
|
so again the "finished" line will be logged against the right context,
|
|||
|
and the <code>with</code> block restores the original context.</p>
|
|||
|
</li>
|
|||
|
</ul>
|
|||
|
<p>As an aside, it's worth noting that <code>handle_request</code> follows our rules</p>
|
|||
|
<ul>
|
|||
|
<li>though that only matters if the caller has its own logcontext which it
|
|||
|
cares about.</li>
|
|||
|
</ul>
|
|||
|
<p>The following sections describe pitfalls and helpful patterns when
|

|
implementing these rules.</p>

<h2 id="always-await-your-awaitables"><a class="header" href="#always-await-your-awaitables">Always await your awaitables</a></h2>
|

<p>Whenever you get an awaitable back from a function, you should <code>await</code> on

it as soon as possible. Do not pass go; do not do any logging; do not

call any other functions.</p>

return result
|
|||
|
</code></pre>
|
|||
|
<p>Provided this pattern is followed all the way back up to the callchain
|
|||
|
to where the logcontext was set, this will make things work out ok:
|
|||
|
provided <code>do_some_stuff</code> and <code>more_stuff</code> follow the rules above, then
|
|||
|
so will <code>fun</code>.</p>
|
|||
|
<p>It's all too easy to forget to <code>await</code>: for instance if we forgot that
|
|||
|
<code>do_some_stuff</code> returned an awaitable, we might plough on regardless. This
|
|||
|
leads to a mess; it will probably work itself out eventually, but not
|
|||
|
before a load of stuff has been logged against the wrong context.
|
|||
|
(Normally, other things will break, more obviously, if you forget to
|
|||
|
<code>await</code>, so this tends not to be a major problem in practice.)</p>
|
|||
|
<p>Of course sometimes you need to do something a bit fancier with your
|
|||
|
awaitable - not all code follows the linear A-then-B-then-C pattern.
|
|||
|
Notes on implementing more complex patterns are in later sections.</p>

|
|||
|
<p>Most of the time, an awaitable comes from another synapse function.
|
|||
|
Sometimes, though, we need to make up a new awaitable, or we get an awaitable
|
|||
|
back from external code. We need to make it follow our rules.</p>
|
|||
|
<p>The easy way to do it is by using <code>context.make_deferred_yieldable</code>. Suppose we want to implement
|
|||
|
<code>sleep</code>, which returns a deferred which will run its callbacks after a
|
|||
|
given number of seconds. That might look like:</p>
|
|||
|
<pre><code class="language-python"># not a logcontext-rules-compliant function
|
|||
|
def get_sleep_deferred(seconds):
|
|||
|
d = defer.Deferred()
|
|||
|
reactor.callLater(seconds, d.callback, None)
|
|||
|
return d
|
|||
|
</code></pre>
|
|||
|
<p>That doesn't follow the rules, but we can fix it by calling it through
|
|||
|
<code>context.make_deferred_yieldable</code>:</p>
|
|||
|
<pre><code class="language-python">async def sleep(seconds):
|
|||
|
return await context.make_deferred_yieldable(get_sleep_deferred(seconds))
|
|||
|
</code></pre>
|
|||
|
<h2 id="fire-and-forget"><a class="header" href="#fire-and-forget">Fire-and-forget</a></h2>
|
|||
|
<p>Sometimes you want to fire off a chain of execution, but not wait for
|
|||
|
its result. That might look a bit like this:</p>
|
|||
|
<pre><code class="language-python">async def do_request_handling():
|
|||
|
await foreground_operation()
|
|||
|
|
|||
|
# *don't* do this
|
|||
|
background_operation()
|
|||
|
|
|||
|
logger.debug("Request handling complete")
|
|||
|
|
|||
|
async def background_operation():
|
|||
|
await first_background_step()
|
|||
|
logger.debug("Completed first step")
|
|||
|
await second_background_step()
|
|||
|
logger.debug("Completed second step")
|
|||
|
</code></pre>
|
|||
|
<p>The above code does a couple of steps in the background after
|
|||
|
<code>do_request_handling</code> has finished. The log lines are still logged
|
|||
|
against the <code>request_context</code> logcontext, which may or may not be
|
|||
|
desirable. There are two big problems with the above, however. The first
|
|||
|
problem is that, if <code>background_operation</code> returns an incomplete
|
|||
|
awaitable, it will expect its caller to <code>await</code> immediately, so will have
|
|||
|
cleared the logcontext. In this example, that means that 'Request
|
|||
|
handling complete' will be logged without any context.</p>
|
|||
|
<p>The second problem, which is potentially even worse, is that when the
|
|||
|
awaitable returned by <code>background_operation</code> completes, it will restore
|
|||
|
the original logcontext. There is nothing waiting on that awaitable, so
|
|||
|
the logcontext will leak into the reactor and possibly get attached to
|
|||
|
some arbitrary future operation.</p>
|
|||
|
<p>There are two potential solutions to this.</p>
|
|||
|
<p>One option is to surround the call to <code>background_operation</code> with a
|
|||
|
<code>PreserveLoggingContext</code> call. That will reset the logcontext before
|
|||
|
starting <code>background_operation</code> (so the context restored when the
|
|||
|
deferred completes will be the empty logcontext), and will restore the
|
|||
|
current logcontext before continuing the foreground process:</p>
|
|||
|
<pre><code class="language-python">async def do_request_handling():
|
|||
|
await foreground_operation()
|
|||
|
|
|||
|
# start background_operation off in the empty logcontext, to
|
|||
|
# avoid leaking the current context into the reactor.
|
|||
|
with PreserveLoggingContext():
|
|||
|
background_operation()
|
|||
|
|
|||
|
# this will now be logged against the request context
|
|||
|
logger.debug("Request handling complete")
|
|||
|
</code></pre>
|
|||
|
<p>Obviously that option means that the operations done in
|
|||
|
<code>background_operation</code> would be not be logged against a logcontext
|
|||
|
(though that might be fixed by setting a different logcontext via a
|
|||
|
<code>with LoggingContext(...)</code> in <code>background_operation</code>).</p>
|
|||
|
<p>The second option is to use <code>context.run_in_background</code>, which wraps a
|
|||
|
function so that it doesn't reset the logcontext even when it returns
|
|||
|
an incomplete awaitable, and adds a callback to the returned awaitable to
|
|||
|
reset the logcontext. In other words, it turns a function that follows
|
|||
|
the Synapse rules about logcontexts and awaitables into one which behaves
|
|||
|
more like an external function --- the opposite operation to that
|
|||
|
described in the previous section. It can be used like this:</p>
|
|||
|
<pre><code class="language-python">async def do_request_handling():
|
|||
|
await foreground_operation()
|
|||
|
|
|||
|
context.run_in_background(background_operation)
|
|||
|
|
|||
|
# this will now be logged against the request context
|
|||
|
logger.debug("Request handling complete")
|
|||
|
</code></pre>

|
<h2 id="passing-synapse-deferreds-into-third-party-functions"><a class="header" href="#passing-synapse-deferreds-into-third-party-functions">Passing synapse deferreds into third-party functions</a></h2>
|
|||
|
<p>A typical example of this is where we want to collect together two or
|
|||
|
more awaitables via <code>defer.gatherResults</code>:</p>
|
|||
|
<pre><code class="language-python">a1 = operation1()
|
|||
|
a2 = operation2()
|
|||
|
a3 = defer.gatherResults([a1, a2])
|
|||
|
</code></pre>
|
|||
|
<p>This is really a variation of the fire-and-forget problem above, in that
|
|||
|
we are firing off <code>a1</code> and <code>a2</code> without awaiting on them. The difference
|
|||
|
is that we now have third-party code attached to their callbacks. Anyway
|
|||
|
either technique given in the <a href="log_contexts.html#fire-and-forget">Fire-and-forget</a>
|
|||
|
section will work.</p>
|
|||
|
<p>Of course, the new awaitable returned by <code>gather</code> needs to be
|
|||
|
wrapped in order to make it follow the logcontext rules before we can
|
|||
|
yield it, as described in <a href="log_contexts.html#where-you-create-a-new-awaitable-make-it-follow-the-rules">Where you create a new awaitable, make it
|
|||
|
follow the
|
|||
|
rules</a>.</p>
|
|||
|
<p>So, option one: reset the logcontext before starting the operations to
|
|||
|
be gathered:</p>
|
|||
|
<pre><code class="language-python">async def do_request_handling():
|
|||
|
with PreserveLoggingContext():
|
|||
|
a1 = operation1()
|
|||
|
a2 = operation2()
|
|||
|
result = await defer.gatherResults([a1, a2])
|
|||
|
</code></pre>
|
|||
|
<p>In this case particularly, though, option two, of using
|
|||
|
<code>context.run_in_background</code> almost certainly makes more sense, so that
|
|||
|
<code>operation1</code> and <code>operation2</code> are both logged against the original
|
|||
|
logcontext. This looks like:</p>
|
|||
|
<pre><code class="language-python">async def do_request_handling():
|
|||
|
a1 = context.run_in_background(operation1)
|
|||
|
a2 = context.run_in_background(operation2)
|
|||
|
|
|||
|
result = await make_deferred_yieldable(defer.gatherResults([a1, a2]))
|
|||
|
</code></pre>
|
|||
|
<h2 id="a-note-on-garbage-collection-of-awaitable-chains"><a class="header" href="#a-note-on-garbage-collection-of-awaitable-chains">A note on garbage-collection of awaitable chains</a></h2>
|
|||
|
<p>It turns out that our logcontext rules do not play nicely with awaitable
|
|||
|
chains which get orphaned and garbage-collected.</p>
|
|||
|
<p>Imagine we have some code that looks like this:</p>
|
|||
|
<pre><code class="language-python">listener_queue = []
|
|||
|
|
|||
|
def on_something_interesting():
|
|||
|
for d in listener_queue:
|
|||
|
d.callback("foo")
|
|||
|
|
|||
|
async def await_something_interesting():
|
|||
|
new_awaitable = defer.Deferred()
|
|||
|
listener_queue.append(new_awaitable)
|
|||
|
|
|||
|
with PreserveLoggingContext():
|
|||
|
await new_awaitable
|
|||
|
</code></pre>
|
|||
|
<p>Obviously, the idea here is that we have a bunch of things which are
|
|||
|
waiting for an event. (It's just an example of the problem here, but a
|
|||
|
relatively common one.)</p>
|
|||
|
<p>Now let's imagine two further things happen. First of all, whatever was
|
|||
|
waiting for the interesting thing goes away. (Perhaps the request times
|
|||
|
out, or something <em>even more</em> interesting happens.)</p>
|
|||
|
<p>Secondly, let's suppose that we decide that the interesting thing is
|
|||
|
never going to happen, and we reset the listener queue:</p>
|
|||
|
<pre><code class="language-python">def reset_listener_queue():
|
|||
|
listener_queue.clear()
|
|||
|
</code></pre>
|
|||
|
<p>So, both ends of the awaitable chain have now dropped their references,
|
|||
|
and the awaitable chain is now orphaned, and will be garbage-collected at
|
|||
|
some point. Note that <code>await_something_interesting</code> is a coroutine,
|
|||
|
which Python implements as a generator function. When Python
|
|||
|
garbage-collects generator functions, it gives them a chance to
|
|||
|
clean up by making the <code>await</code> (or <code>yield</code>) raise a <code>GeneratorExit</code>
|
|||
|
exception. In our case, that means that the <code>__exit__</code> handler of
|
|||
|
<code>PreserveLoggingContext</code> will carefully restore the request context, but
|
|||
|
there is now nothing waiting for its return, so the request context is
|
|||
|
never cleared.</p>
|
|||
|
<p>To reiterate, this problem only arises when <em>both</em> ends of a awaitable
|
|||
|
chain are dropped. Dropping the the reference to an awaitable you're
|
|||
|
supposed to be awaiting is bad practice, so this doesn't
|
|||
|
actually happen too much. Unfortunately, when it does happen, it will
|
|||
|
lead to leaked logcontexts which are incredibly hard to track down.</p>

|
|||
|
<p>We'd like to be able to split some of the work that synapse does into
|
|||
|
multiple python processes. In theory multiple synapse processes could
|
|||
|
share a single postgresql database and we'd scale up by running more
|
|||
|
synapse processes. However much of synapse assumes that only one process
|
|||
|
is interacting with the database, both for assigning unique identifiers
|
|||
|
when inserting into tables, notifying components about new updates, and
|
|||
|
for invalidating its caches.</p>
|
|||
|
<p>So running multiple copies of the current code isn't an option. One way
|
|||
|
to run multiple processes would be to have a single writer process and
|
|||
|
multiple reader processes connected to the same database. In order to do
|
|||
|
this we'd need a way for the reader process to invalidate its in-memory
|
|||
|
caches when an update happens on the writer. One way to do this is for
|
|||
|
the writer to present an append-only log of updates which the readers
|
|||
|
can consume to invalidate their caches and to push updates to listening
|
|||
|
clients or pushers.</p>
|
|||
|
<p>Synapse already stores much of its data as an append-only log so that it
|
|||
|
can correctly respond to <code>/sync</code> requests so the amount of code changes
|
|||
|
needed to expose the append-only log to the readers should be fairly
|
|||
|
minimal.</p>

<p>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.</p>
|
|||
|
<h2 id="overview-3"><a class="header" href="#overview-3">Overview</a></h2>
|
|||
|
<p>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):</p>
|
|||
|
<pre><code>> SERVER example.com
|
|||
|
< REPLICATE
|
|||
|
> POSITION events master 53 53
|
|||
|
> RDATA events master 54 ["$foo1:bar.com", ...]
|
|||
|
> RDATA events master 55 ["$foo4:bar.com", ...]
|
|||
|
</code></pre>
|
|||
|
<p>The example shows the server accepting a new connection and sending its identity
|
|||
|
with the <code>SERVER</code> command, followed by the client server to respond with the
|
|||
|
position of all streams. The server then periodically sends <code>RDATA</code> commands
|
|||
|
which have the format <code>RDATA <stream_name> <instance_name> <token> <row></code>, where
|
|||
|
the format of <code><row></code> is defined by the individual streams. The
|
|||
|
<code><instance_name></code> is the name of the Synapse process that generated the data
|
|||
|
(usually "master").</p>
|
|||
|
<p>Error reporting happens by either the client or server sending an ERROR
|
|||
|
command, and usually the connection will be closed.</p>
|
|||
|
<p>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:</p>
|
|||
|
<ul>
|
|||
|
<li>The federation stream is only available if federation sending has
|
|||
|
been disabled on the main process.</li>
|
|||
|
<li>The server will only time connections out that have sent a <code>PING</code>
|
|||
|
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 <code>PING</code>).</li>
|
|||
|
<li><code>RDATA</code> commands <em>usually</em> include a numeric token, however if the
|
|||
|
stream has multiple rows to replicate per token the server will send
|
|||
|
multiple <code>RDATA</code> commands, with all but the last having a token of
|
|||
|
<code>batch</code>. See the documentation on <code>commands.RdataCommand</code> for
|
|||
|
further details.</li>
|
|||
|
</ul>
|
|||
|
<h2 id="architecture-1"><a class="header" href="#architecture-1">Architecture</a></h2>
|
|||
|
<p>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:</p>
|
|||
|
<pre><code>RDATA <stream_name> <instance_name> <token> <row_json>
|
|||
|
</code></pre>
|
|||
|
<p>(Note that <row_json> may contains spaces, but cannot contain
|
|||
|
newlines.)</p>
|
|||
|
<p>Blank lines are ignored.</p>
|
|||
|
<h3 id="keep-alives"><a class="header" href="#keep-alives">Keep alives</a></h3>
|
|||
|
<p>Both sides are expected to send at least one command every 5s or so, and
|
|||
|
should send a <code>PING</code> command if necessary. If either side do not receive
|
|||
|
a command within e.g. 15s then the connection should be closed.</p>
|
|||
|
<p>Because the server may be connected to manually using e.g. netcat, the
|
|||
|
timeouts aren't enabled until an initial <code>PING</code> command is seen. Both
|
|||
|
the client and server implementations below send a <code>PING</code> command
|
|||
|
immediately on connection to ensure the timeouts are enabled.</p>
|
|||
|
<p>This ensures that both sides can quickly realize if the tcp connection
|
|||
|
has gone and handle the situation appropriately.</p>
|
|||
|
<h3 id="start-up"><a class="header" href="#start-up">Start up</a></h3>
|
|||
|
<p>When a new connection is made, the server:</p>
|
|||
|
<ul>
|
|||
|
<li>Sends a <code>SERVER</code> command, which includes the identity of the server,
|
|||
|
allowing the client to detect if its connected to the expected
|
|||
|
server</li>
|
|||
|
<li>Sends a <code>PING</code> command as above, to enable the client to time out
|
|||
|
connections promptly.</li>
|
|||
|
</ul>
|
|||
|
<p>The client:</p>
|
|||
|
<ul>
|
|||
|
<li>Sends a <code>NAME</code> command, allowing the server to associate a human
|
|||
|
friendly name with the connection. This is optional.</li>
|
|||
|
<li>Sends a <code>PING</code> as above</li>
|
|||
|
<li>Sends a <code>REPLICATE</code> to get the current position of all streams.</li>
|
|||
|
<li>On receipt of a <code>SERVER</code> command, checks that the server name
|
|||
|
matches the expected server name.</li>
|
|||
|
</ul>
|
|||
|
<h3 id="error-handling"><a class="header" href="#error-handling">Error handling</a></h3>
|
|||
|
<p>If either side detects an error it can send an <code>ERROR</code> command and close
|
|||
|
the connection.</p>
|
|||
|
<p>If the client side loses the connection to the server it should
|
|||
|
reconnect, following the steps above.</p>
|
|||
|
<h3 id="congestion"><a class="header" href="#congestion">Congestion</a></h3>
|
|||
|
<p>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.</p>
|
|||
|
<h3 id="reliability"><a class="header" href="#reliability">Reliability</a></h3>
|
|||
|
<p>In general the replication stream should be considered an unreliable
|
|||
|
transport since e.g. commands are not resent if the connection
|
|||
|
disappears.</p>
|
|||
|
<p>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.</p>
|
|||
|
<p>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 <code>RdataCommand</code> for more details.</p>

<p>The <code>POSITION</code> command sent by the server is used to set the clients

|
position without needing to send data with the <code>RDATA</code> command.</p>
|
|||
|
<p>An example of a batched set of <code>RDATA</code> is:</p>
|
|||
|
<pre><code>> RDATA caches master batch ["get_user_by_id",["@test:localhost:8823"],1490197670513]

|

<p>The POSITION command includes the source of the stream. Currently all streams

<h3 id="cache-invalidation-stream"><a class="header" href="#cache-invalidation-stream">Cache Invalidation Stream</a></h3>
|
|||
|
<p>The cache invalidation stream is used to inform workers when they need
|
|||
|
to invalidate any of their caches in the data store. This is done by
|
|||
|
streaming all cache invalidations done on master down to the workers,
|
|||
|
assuming that any caches on the workers also exist on the master.</p>
|
|||
|
<p>Each individual cache invalidation results in a row being sent down
|
|||
|
replication, which includes the cache name (the name of the function)
|
|||
|
and they key to invalidate. For example:</p>
|
|||
|
<pre><code>> RDATA caches master 550953771 ["get_user_by_id", ["@bob:example.com"], 1550574873251]
|
|||
|
</code></pre>
|
|||
|
<p>Alternatively, an entire cache can be invalidated by sending down a <code>null</code>
|
|||
|
instead of the key. For example:</p>
|
|||
|
<pre><code>> RDATA caches master 550953772 ["get_user_by_id", null, 1550574873252]
|
|||
|
</code></pre>
|
|||
|
<p>However, there are times when a number of caches need to be invalidated
|
|||
|
at the same time with the same key. To reduce traffic we batch those
|
|||
|
invalidations into a single poke by defining a special cache name that
|
|||
|
workers understand to mean to expand to invalidate the correct caches.</p>
|
|||
|
<p>Currently the special cache names are declared in
|
|||
|
<code>synapse/storage/_base.py</code> and are:</p>
|
|||
|
<ol>
|
|||
|
<li><code>cs_cache_fake</code> ─ invalidates caches that depend on the current
|
|||
|
state</li>
|
|||
|
</ol>

|
<p>https://capriza.github.io/samling/samling.html (https://github.com/capriza/samling) is a great
|

|
resource for being able to tinker with the SAML options within Synapse without needing to

|
deploy and configure a complicated software stack.</p>
|
|||
|
<p>To make Synapse (and therefore Riot) use it:</p>
|
|||
|
<ol>
|
|||
|
<li>Use the samling.html URL above or deploy your own and visit the IdP Metadata tab.</li>
|
|||
|
<li>Copy the XML to your clipboard.</li>
|
|||
|
<li>On your Synapse server, create a new file <code>samling.xml</code> next to your <code>homeserver.yaml</code> with
|
|||
|
the XML from step 2 as the contents.</li>
|
|||
|
<li>Edit your <code>homeserver.yaml</code> to include:
|
|||
|
<pre><code class="language-yaml">saml2_config:
|

|||
|
local: ["samling.xml"]
|
|||
|
</code></pre>
|
|||
|
</li>
|
|||
|
<li>Ensure that your <code>homeserver.yaml</code> has a setting for <code>public_baseurl</code>:
|
|||
|
<pre><code class="language-yaml">public_baseurl: http://localhost:8080/
|
|||
|
</code></pre>
|
|||
|
</li>
|
|||
|
<li>Run <code>apt-get install xmlsec1</code> and <code>pip install --upgrade --force 'pysaml2>=4.5.0'</code> to ensure
|
|||
|
the dependencies are installed and ready to go.</li>
|
|||
|
<li>Restart Synapse.</li>
|
|||
|
</ol>
|
|||
|
<p>Then in Riot:</p>
|
|||
|
<ol>
|
|||
|
<li>Visit the login page with a Riot pointing at your homeserver.</li>
|
|||
|
<li>Click the Single Sign-On button.</li>
|
|||
|
<li>On the samling page, enter a Name Identifier and add a SAML Attribute for <code>uid=your_localpart</code>.
|
|||
|
The response must also be signed.</li>
|

|
<li>Click "Next".</li>
|

<li>Click "Post Response" (change nothing).</li>
|

<li>You should be logged in.</li>

</ol>
|

|
<p>If you try and repeat this process, you may be automatically logged in using the information you
|

|
gave previously. To fix this, open your developer console (<code>F12</code> or <code>Ctrl+Shift+I</code>) while on the
|
|||
|
samling page and clear the site data. In Chrome, this will be a button on the Application tab.</p>

|

<h2 id="edges"><a class="header" href="#edges">Edges</a></h2>
|
|||
|
<p>The word "edge" comes from graph theory lingo. An edge is just a connection
|
|||
|
between two events. In Synapse, we connect events by specifying their
|
|||
|
<code>prev_events</code>. A subsequent event points back at a previous event.</p>
|
|||
|
<pre><code>A (oldest) <---- B <---- C (most recent)
|
|||
|
</code></pre>
|
|||
|
<h2 id="depth-and-stream-ordering"><a class="header" href="#depth-and-stream-ordering">Depth and stream ordering</a></h2>
|
|||
|
<p>Events are normally sorted by <code>(topological_ordering, stream_ordering)</code> where
|
|||
|
<code>topological_ordering</code> is just <code>depth</code>. In other words, we first sort by <code>depth</code>
|
|||
|
and then tie-break based on <code>stream_ordering</code>. <code>depth</code> is incremented as new
|
|||
|
messages are added to the DAG. Normally, <code>stream_ordering</code> is an auto
|
|||
|
incrementing integer, but backfilled events start with <code>stream_ordering=-1</code> and decrement.</p>
|
|||
|
<hr />
|
|||
|
<ul>
|
|||
|
<li><code>/sync</code> returns things in the order they arrive at the server (<code>stream_ordering</code>).</li>
|
|||
|
<li><code>/messages</code> (and <code>/backfill</code> in the federation API) return them in the order determined by the event graph <code>(topological_ordering, stream_ordering)</code>.</li>
|
|||
|
</ul>
|
|||
|
<p>The general idea is that, if you're following a room in real-time (i.e.
|
|||
|
<code>/sync</code>), you probably want to see the messages as they arrive at your server,
|
|||
|
rather than skipping any that arrived late; whereas if you're looking at a
|
|||
|
historical section of timeline (i.e. <code>/messages</code>), you want to see the best
|
|||
|
representation of the state of the room as others were seeing it at the time.</p>
|
|||
|
<h2 id="forward-extremity"><a class="header" href="#forward-extremity">Forward extremity</a></h2>
|
|||
|
<p>Most-recent-in-time events in the DAG which are not referenced by any other events' <code>prev_events</code> yet.</p>
|
|||
|
<p>The forward extremities of a room are used as the <code>prev_events</code> when the next event is sent.</p>
|
|||
|
<h2 id="backwards-extremity"><a class="header" href="#backwards-extremity">Backwards extremity</a></h2>
|
|||
|
<p>The current marker of where we have backfilled up to and will generally be the
|
|||
|
oldest-in-time events we know of in the DAG.</p>
|
|||
|
<p>This is an event where we haven't fetched all of the <code>prev_events</code> for.</p>
|
|||
|
<p>Once we have fetched all of its <code>prev_events</code>, it's unmarked as a backwards
|
|||
|
extremity (although we may have formed new backwards extremities from the prev
|
|||
|
events during the backfilling process).</p>
|
|||
|
<h2 id="outliers"><a class="header" href="#outliers">Outliers</a></h2>
|
|||
|
<p>We mark an event as an <code>outlier</code> when we haven't figured out the state for the
|
|||
|
room at that point in the DAG yet.</p>
|
|||
|
<p>We won't <em>necessarily</em> have the <code>prev_events</code> of an <code>outlier</code> in the database,
|
|||
|
but it's entirely possible that we <em>might</em>. The status of whether we have all of
|
|||
|
the <code>prev_events</code> is marked as a <a href="development/room-dag-concepts.html#backwards-extremity">backwards extremity</a>.</p>
|
|||
|
<p>For example, when we fetch the event auth chain or state for a given event, we
|
|||
|
mark all of those claimed auth events as outliers because we haven't done the
|
|||
|
state calculation ourself.</p>
|
|||
|
<h2 id="state-groups"><a class="header" href="#state-groups">State groups</a></h2>
|
|||
|
<p>For every non-outlier event we need to know the state at that event. Instead of
|
|||
|
storing the full state for each event in the DB (i.e. a <code>event_id -> state</code>
|
|||
|
mapping), which is <em>very</em> space inefficient when state doesn't change, we
|
|||
|
instead assign each different set of state a "state group" and then have
|
|||
|
mappings of <code>event_id -> state_group</code> and <code>state_group -> state</code>.</p>

|
|||
|
<p>The auth chain difference algorithm is used by V2 state resolution, where a
|
|||
|
naive implementation can be a significant source of CPU and DB usage.</p>
|
|||
|
<h3 id="definitions"><a class="header" href="#definitions">Definitions</a></h3>
|
|||
|
<p>A <em>state set</em> is a set of state events; e.g. the input of a state resolution
|
|||
|
algorithm is a collection of state sets.</p>
|
|||
|
<p>The <em>auth chain</em> of a set of events are all the events' auth events and <em>their</em>
|
|||
|
auth events, recursively (i.e. the events reachable by walking the graph induced
|
|||
|
by an event's auth events links).</p>
|
|||
|
<p>The <em>auth chain difference</em> of a collection of state sets is the union minus the
|
|||
|
intersection of the sets of auth chains corresponding to the state sets, i.e an
|
|||
|
event is in the auth chain difference if it is reachable by walking the auth
|
|||
|
event graph from at least one of the state sets but not from <em>all</em> of the state
|
|||
|
sets.</p>
|
|||
|
<h2 id="breadth-first-walk-algorithm"><a class="header" href="#breadth-first-walk-algorithm">Breadth First Walk Algorithm</a></h2>
|
|||
|
<p>A way of calculating the auth chain difference without calculating the full auth
|
|||
|
chains for each state set is to do a parallel breadth first walk (ordered by
|
|||
|
depth) of each state set's auth chain. By tracking which events are reachable
|
|||
|
from each state set we can finish early if every pending event is reachable from
|
|||
|
every state set.</p>
|
|||
|
<p>This can work well for state sets that have a small auth chain difference, but
|
|||
|
can be very inefficient for larger differences. However, this algorithm is still
|
|||
|
used if we don't have a chain cover index for the room (e.g. because we're in
|
|||
|
the process of indexing it).</p>
|
|||
|
<h2 id="chain-cover-index"><a class="header" href="#chain-cover-index">Chain Cover Index</a></h2>
|
|||
|
<p>Synapse computes auth chain differences by pre-computing a "chain cover" index
|
|||
|
for the auth chain in a room, allowing efficient reachability queries like "is
|
|||
|
event A in the auth chain of event B". This is done by assigning every event a
|
|||
|
<em>chain ID</em> and <em>sequence number</em> (e.g. <code>(5,3)</code>), and having a map of <em>links</em>
|
|||
|
between chains (e.g. <code>(5,3) -> (2,4)</code>) such that A is reachable by B (i.e. <code>A</code>
|
|||
|
is in the auth chain of <code>B</code>) if and only if either:</p>
|
|||
|
<ol>
|
|||
|
<li>A and B have the same chain ID and <code>A</code>'s sequence number is less than <code>B</code>'s
|
|||
|
sequence number; or</li>
|
|||
|
<li>there is a link <code>L</code> between <code>B</code>'s chain ID and <code>A</code>'s chain ID such that
|
|||
|
<code>L.start_seq_no</code> <= <code>B.seq_no</code> and <code>A.seq_no</code> <= <code>L.end_seq_no</code>.</li>
|
|||
|
</ol>
|
|||
|
<p>There are actually two potential implementations, one where we store links from
|
|||
|
each chain to every other reachable chain (the transitive closure of the links
|
|||
|
graph), and one where we remove redundant links (the transitive reduction of the
|
|||
|
links graph) e.g. if we have chains <code>C3 -> C2 -> C1</code> then the link <code>C3 -> C1</code>
|
|||
|
would not be stored. Synapse uses the former implementations so that it doesn't
|
|||
|
need to recurse to test reachability between chains.</p>
|
|||
|
<h3 id="example-4"><a class="header" href="#example-4">Example</a></h3>
|
|||
|
<p>An example auth graph would look like the following, where chains have been
|
|||
|
formed based on type/state_key and are denoted by colour and are labelled with
|
|||
|
<code>(chain ID, sequence number)</code>. Links are denoted by the arrows (links in grey
|
|||
|
are those that would be remove in the second implementation described above).</p>
|
|||
|
<p><img src="auth_chain_diff.dot.png" alt="Example" /></p>
|
|||
|
<p>Note that we don't include all links between events and their auth events, as
|
|||
|
most of those links would be redundant. For example, all events point to the
|
|||
|
create event, but each chain only needs the one link from it's base to the
|
|||
|
create event.</p>
|
|||
|
<h2 id="using-the-index"><a class="header" href="#using-the-index">Using the Index</a></h2>
|
|||
|
<p>This index can be used to calculate the auth chain difference of the state sets
|
|||
|
by looking at the chain ID and sequence numbers reachable from each state set:</p>
|
|||
|
<ol>
|
|||
|
<li>For every state set lookup the chain ID/sequence numbers of each state event</li>
|
|||
|
<li>Use the index to find all chains and the maximum sequence number reachable
|
|||
|
from each state set.</li>
|
|||
|
<li>The auth chain difference is then all events in each chain that have sequence
|
|||
|
numbers between the maximum sequence number reachable from <em>any</em> state set and
|
|||
|
the minimum reachable by <em>all</em> state sets (if any).</li>
|
|||
|
</ol>
|
|||
|
<p>Note that steps 2 is effectively calculating the auth chain for each state set
|
|||
|
(in terms of chain IDs and sequence numbers), and step 3 is calculating the
|
|||
|
difference between the union and intersection of the auth chains.</p>
|
|||
|
<h3 id="worked-example"><a class="header" href="#worked-example">Worked Example</a></h3>
|
|||
|
<p>For example, given the above graph, we can calculate the difference between
|
|||
|
state sets consisting of:</p>
|
|||
|
<ol>
|
|||
|
<li><code>S1</code>: Alice's invite <code>(4,1)</code> and Bob's second join <code>(2,2)</code>; and</li>
|
|||
|
<li><code>S2</code>: Alice's second join <code>(4,3)</code> and Bob's first join <code>(2,1)</code>.</li>
|
|||
|
</ol>
|
|||
|
<p>Using the index we see that the following auth chains are reachable from each
|
|||
|
state set:</p>
|
|||
|
<ol>
|
|||
|
<li><code>S1</code>: <code>(1,1)</code>, <code>(2,2)</code>, <code>(3,1)</code> & <code>(4,1)</code></li>
|
|||
|
<li><code>S2</code>: <code>(1,1)</code>, <code>(2,1)</code>, <code>(3,2)</code> & <code>(4,3)</code></li>
|
|||
|
</ol>
|
|||
|
<p>And so, for each the ranges that are in the auth chain difference:</p>
|
|||
|
<ol>
|
|||
|
<li>Chain 1: None, (since everything can reach the create event).</li>
|
|||
|
<li>Chain 2: The range <code>(1, 2]</code> (i.e. just <code>2</code>), as <code>1</code> is reachable by all state
|
|||
|
sets and the maximum reachable is <code>2</code> (corresponding to Bob's second join).</li>
|
|||
|
<li>Chain 3: Similarly the range <code>(1, 2]</code> (corresponding to the second power
|
|||
|
level).</li>
|
|||
|
<li>Chain 4: The range <code>(1, 3]</code> (corresponding to both of Alice's joins).</li>
|
|||
|
</ol>
|
|||
|
<p>So the final result is: Bob's second join <code>(2,2)</code>, the second power level
|
|||
|
<code>(3,2)</code> and both of Alice's joins <code>(4,2)</code> & <code>(4,3)</code>.</p>

|
The <code>media_id</code> is a randomly chosen, URL safe 24 character string.</p>
|
|||
|
<p>Metadata such as the MIME type, upload time and length are stored in the
|
|||
|
sqlite3 database indexed by <code>media_id</code>.</p>
|
|||
|
<p>Content is stored on the filesystem under a <code>"local_content"</code> directory.</p>
|
|||
|
<p>Thumbnails are stored under a <code>"local_thumbnails"</code> directory.</p>
|
|||
|
<p>The item with <code>media_id</code> <code>"aabbccccccccdddddddddddd"</code> is stored under
|

|
|||
|
<p>Synapse has a number of platform dependencies, including Python and PostgreSQL.
|
|||
|
This document outlines the policy towards which versions we support, and when we
|
|||
|
drop support for versions in the future.</p>
|
|||
|
<h2 id="policy"><a class="header" href="#policy">Policy</a></h2>
|
|||
|
<p>Synapse follows the upstream support life cycles for Python and PostgreSQL,
|
|||
|
i.e. when a version reaches End of Life Synapse will withdraw support for that
|
|||
|
version in future releases.</p>
|
|||
|
<p>Details on the upstream support life cycles for Python and PostgreSQL are
|
|||
|
documented at https://endoflife.date/python and
|
|||
|
https://endoflife.date/postgresql.</p>
|
|||
|
<h2 id="context"><a class="header" href="#context">Context</a></h2>
|
|||
|
<p>It is important for system admins to have a clear understanding of the platform
|
|||
|
requirements of Synapse and its deprecation policies so that they can
|
|||
|
effectively plan upgrading their infrastructure ahead of time. This is
|
|||
|
especially important in contexts where upgrading the infrastructure requires
|
|||
|
auditing and approval from a security team, or where otherwise upgrading is a
|
|||
|
long process.</p>
|
|||
|
<p>By following the upstream support life cycles Synapse can ensure that its
|
|||
|
dependencies continue to get security patches, while not requiring system admins
|
|||
|
to constantly update their platform dependencies to the latest versions.</p>
