<h1 id="2-what-do-i-need"><a class="header" href="#2-what-do-i-need">2. What do I need?</a></h1>
|
||
<p>If you are running Windows, the Windows Subsystem for Linux (WSL) is strongly
|
||
recommended for development. More information about WSL can be found at
|
||
<a href="https://docs.microsoft.com/en-us/windows/wsl/install">https://docs.microsoft.com/en-us/windows/wsl/install</a>. Running Synapse natively
|
||
on Windows is not officially supported.</p>
|
||
<p>The code of Synapse is written in Python 3. To do pretty much anything, you’ll need <a href="https://www.python.org/downloads/">a recent version of Python 3</a>. Your Python also needs support for <a href="https://docs.python.org/3/library/venv.html">virtual environments</a>. This is usually built-in, but some Linux distributions like Debian and Ubuntu split it out into its own package. Running <code>sudo apt install python3-venv</code> should be enough.</p>
|
||
<p>A recent version of the Rust compiler is needed to build the native modules. The
|
||
easiest way of installing the latest version is to use <a href="https://rustup.rs/">rustup</a>.</p>
|
||
<p>Synapse can connect to PostgreSQL via the <a href="https://pypi.org/project/psycopg2/">psycopg2</a> Python library. Building this library from source requires access to PostgreSQL’s C header files. On Debian or Ubuntu Linux, these can be installed with <code>sudo apt install libpq-dev</code>.</p>
|
||
<p>The source code of Synapse is hosted on GitHub. You will also need <a href="https://github.com/git-guides/install-git">a recent version of git</a>.</p>
|
||
<p>For some tests, you will need <a href="https://docs.docker.com/get-docker/">a recent version of Docker</a>.</p>
|
||
<h1 id="3-get-the-source"><a class="header" href="#3-get-the-source">3. Get the source.</a></h1>
|
||
<p>The preferred and easiest way to contribute changes is to fork the relevant
|
||
project on GitHub, and then <a href="https://help.github.com/articles/using-pull-requests/">create a pull request</a> to ask us to pull your
|
||
changes into our repo.</p>
|
||
<p>Please base your changes on the <code>develop</code> branch.</p>
|
||
<pre><code class="language-sh">git clone git@github.com:YOUR_GITHUB_USER_NAME/synapse.git
|
||
git checkout develop
|
||
</code></pre>
|
||
<p>If you need help getting started with git, this is beyond the scope of the document, but you
|
||
can find many good git tutorials on the web.</p>
|
||
<h1 id="4-install-the-dependencies"><a class="header" href="#4-install-the-dependencies">4. Install the dependencies</a></h1>
|
||
<p>Before installing the Python dependencies, make sure you have installed a recent version
|
||
of Rust (see the “What do I need?” section above). The easiest way of installing the
|
||
latest version is to use <a href="https://rustup.rs/">rustup</a>.</p>
|
||
<p>Synapse uses the <a href="https://python-poetry.org/">poetry</a> project to manage its dependencies
|
||
and development environment. Once you have installed Python 3 and added the
|
||
source, you should install <code>poetry</code>.
|
||
Of their installation methods, we recommend
|
||
<a href="https://python-poetry.org/docs/#installing-with-pipx">installing <code>poetry</code> using <code>pipx</code></a>,</p>
|
||
<pre><code class="language-shell">pip install --user pipx
|
||
pipx install poetry
|
||
</code></pre>
|
||
<p>but see poetry’s <a href="https://python-poetry.org/docs/#installation">installation instructions</a>
|
||
for other installation methods.</p>
|
||
<p>Developing Synapse requires Poetry version 1.3.2 or later.</p>
|
||
<p>Next, open a terminal and install dependencies as follows:</p>
|
||
<pre><code class="language-sh">cd path/where/you/have/cloned/the/repository
|
||
poetry install --extras all
|
||
</code></pre>
|
||
<p>This will install the runtime and developer dependencies for the project. Be sure to check
|
||
that the <code>poetry install</code> step completed cleanly.</p>
|
||
<p>For OSX users, be sure to set <code>PKG_CONFIG_PATH</code> to support <code>icu4c</code>. Run <code>brew info icu4c</code> for more details.</p>
|
||
<h2 id="running-synapse-via-poetry"><a class="header" href="#running-synapse-via-poetry">Running Synapse via poetry</a></h2>
|
||
<p>To start a local instance of Synapse in the locked poetry environment, create a config file:</p>
|
||
<pre><code class="language-sh">cp docs/sample_config.yaml homeserver.yaml
|
||
cp docs/sample_log_config.yaml log_config.yaml
|
||
</code></pre>
|
||
<p>Now edit <code>homeserver.yaml</code>, things you might want to change include:</p>
|
||
<ul>
|
||
<li>Set a <code>server_name</code></li>
|
||
<li>Adjusting paths to be correct for your system like the <code>log_config</code> to point to the log config you just copied</li>
|
||
<li>Using a <a href="https://element-hq.github.io/synapse/latest/usage/configuration/config_documentation.html#database">PostgreSQL database instead of SQLite</a></li>
|
||
<li>Adding a <a href="https://element-hq.github.io/synapse/latest/usage/configuration/config_documentation.html#registration_shared_secret"><code>registration_shared_secret</code></a> so you can use <a href="https://element-hq.github.io/synapse/latest/setup/installation.html#registering-a-user"><code>register_new_matrix_user</code> command</a>.</li>
|
||
</ul>
|
||
<p>And then run Synapse with the following command:</p>
|
||
<pre><code class="language-sh">poetry run python -m synapse.app.homeserver -c homeserver.yaml
|
||
</code></pre>
|
||
<p>If you get an error like the following:</p>
|
||
<pre><code>importlib.metadata.PackageNotFoundError: matrix-synapse
|
||
</code></pre>
|
||
<p>this probably indicates that the <code>poetry install</code> step did not complete cleanly - go back and
|
||
resolve any issues and re-run until successful.</p>

<p>When changes are made to any Rust code then you must call either <code>poetry install</code>
|
||
or <code>maturin develop</code> (if installed) to rebuild the Rust code. Using <a href="https://github.com/PyO3/maturin"><code>maturin</code></a>
|
||
is quicker than <code>poetry install</code>, so is recommended when making frequent
|
||
changes to the Rust code.</p>

|

<p>While you’re developing and before submitting a patch, you’ll
|

want to test your code.</p>
|
||
<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>The linter takes no time at all to run as soon as you’ve <a href="#4-install-the-dependencies">downloaded the dependencies</a>.</p>
|
||
<pre><code class="language-sh">poetry run ./scripts-dev/lint.sh
|
||
</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">poetry run ./scripts-dev/lint.sh -d
|
||
</code></pre>
|
||
<p>Or if you know exactly which files you wish to lint, you can instead run:</p>
|
||
<pre><code class="language-sh">poetry run ./scripts-dev/lint.sh path/to/file1.py path/to/file2.py path/to/folder
|
||
</code></pre>
|
||
<h2 id="run-the-unit-tests-twisted-trial"><a class="header" href="#run-the-unit-tests-twisted-trial">Run the unit tests (Twisted trial).</a></h2>
|
||
<p>The unit tests run parts of Synapse, including your changes, to see if anything
|
||
was broken. They are slower than the linters but will typically catch more errors.</p>
|
||
<pre><code class="language-sh">poetry run trial tests
|
||
</code></pre>
|
||
<p>You can run unit tests in parallel by specifying <code>-jX</code> argument to <code>trial</code> where <code>X</code> is the number of parallel runners you want. To use 4 cpu cores, you would run them like:</p>
|
||
<pre><code class="language-sh">poetry run trial -j4 tests
|
||
</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">poetry run trial tests.rest.admin.test_room tests.handlers.test_admin.ExfiltrateData.test_invite
|
||
</code></pre>
|
||
<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>
|
||
<pre><code class="language-sh">SYNAPSE_TEST_LOG_LEVEL=DEBUG poetry run trial tests
|
||
</code></pre>
|
||
<p>By default, tests will use an in-memory SQLite database for test data. For additional
|
||
help with debugging, one can use an on-disk SQLite database file instead, in order to
|
||
review database state during and after running tests. This can be done by setting
|
||
the <code>SYNAPSE_TEST_PERSIST_SQLITE_DB</code> environment variable. Doing so will cause the
|
||
database state to be stored in a file named <code>test.db</code> under the trial process’
|
||
working directory. Typically, this ends up being <code>_trial_temp/test.db</code>. For example:</p>
|
||
<pre><code class="language-sh">SYNAPSE_TEST_PERSIST_SQLITE_DB=1 poetry run trial tests
|
||
</code></pre>
|
||
<p>The database file can then be inspected with:</p>
|
||
<pre><code class="language-sh">sqlite3 _trial_temp/test.db
|
||
</code></pre>
|
||
<p>Note that the database file is cleared at the beginning of each test run. Thus it
|
||
will always only contain the data generated by the <em>last run test</em>. Though generally
|
||
when debugging, one is only running a single test anyway.</p>
|
||
<h3 id="running-tests-under-postgresql"><a class="header" href="#running-tests-under-postgresql">Running tests under PostgreSQL</a></h3>
|
||
<p>Invoking <code>trial</code> as above will use an in-memory SQLite database. This is great for
|
||
quick development and testing. However, we recommend using a PostgreSQL database
|
||
in production (and indeed, we have some code paths specific to each database).
|
||
This means that we need to run our unit tests against PostgreSQL too. Our CI does
|
||
this automatically for pull requests and release candidates, but it’s sometimes
|
||
useful to reproduce this locally.</p>
|
||
<h4 id="using-docker"><a class="header" href="#using-docker">Using Docker</a></h4>
|
||
<p>The easiest way to do so is to run Postgres via a docker container. In one
|
||
terminal:</p>
|
||
<pre><code class="language-shell">docker run --rm -e POSTGRES_PASSWORD=mysecretpassword -e POSTGRES_USER=postgres -e POSTGRES_DB=postgres -p 5432:5432 postgres:14
|
||
</code></pre>
|
||
<p>If you see an error like</p>
|
||
<pre><code>docker: Error response from daemon: driver failed programming external connectivity on endpoint nice_ride (b57bbe2e251b70015518d00c9981e8cb8346b5c785250341a6c53e3c899875f1): Error starting userland proxy: listen tcp4 0.0.0.0:5432: bind: address already in use.
|
||
</code></pre>
|
||
<p>then something is already bound to port 5432. You’re probably already running postgres locally.</p>
|
||
<p>Once you have a postgres server running, invoke <code>trial</code> in a second terminal:</p>
|
||
<pre><code class="language-shell">SYNAPSE_POSTGRES=1 SYNAPSE_POSTGRES_HOST=127.0.0.1 SYNAPSE_POSTGRES_USER=postgres SYNAPSE_POSTGRES_PASSWORD=mysecretpassword poetry run trial tests
|
||
</code></pre>
|
||
<h4 id="using-an-existing-postgres-installation"><a class="header" href="#using-an-existing-postgres-installation">Using an existing Postgres installation</a></h4>
|
||
<p>If you have postgres already installed on your system, you can run <code>trial</code> with the
|
||
following environment variables matching your configuration:</p>
|
||
<ul>
|
||
<li><code>SYNAPSE_POSTGRES</code> to anything nonempty</li>
|
||
<li><code>SYNAPSE_POSTGRES_HOST</code> (optional if it’s the default: UNIX socket)</li>
|
||
<li><code>SYNAPSE_POSTGRES_PORT</code> (optional if it’s the default: 5432)</li>
|
||
<li><code>SYNAPSE_POSTGRES_USER</code> (optional if using a UNIX socket)</li>
|
||
<li><code>SYNAPSE_POSTGRES_PASSWORD</code> (optional if using a UNIX socket)</li>
|
||
</ul>
|
||
<p>For example:</p>
|
||
<pre><code class="language-shell">export SYNAPSE_POSTGRES=1
|
||
export SYNAPSE_POSTGRES_HOST=localhost
|
||
export SYNAPSE_POSTGRES_USER=postgres
|
||
export SYNAPSE_POSTGRES_PASSWORD=mydevenvpassword
|
||
trial
|
||
</code></pre>
|
||
<p>You don’t need to specify the host, user, port or password if your Postgres
|
||
server is set to authenticate you over the UNIX socket (i.e. if the <code>psql</code> command
|
||
works without further arguments).</p>
|
||
<p>Your Postgres account needs to be able to create databases; see the postgres
|
||
docs for <a href="https://www.postgresql.org/docs/current/sql-alterrole.html"><code>ALTER ROLE</code></a>.</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:bookworm
|
||
</code></pre>
|
||
<p>(Note that the paths must be full paths! You could also write <code>$(realpath relative/path)</code> if needed.)</p>
|
||
<p>This configuration should generally cover your needs.</p>
|
||
<ul>
|
||
<li>To run with Postgres, supply the <code>-e POSTGRES=1 -e MULTI_POSTGRES=1</code> environment flags.</li>
|
||
<li>To run with Synapse in worker mode, supply the <code>-e WORKERS=1 -e REDIS=1</code> environment flags (in addition to the Postgres flags).</li>
|
||
</ul>

</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/twisted/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/element-hq/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 must 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 and file extension should be the same. Towncrier
|
||
will merge the matching files together into a single changelog entry when we come to
|
||
release.</p>

|
||
<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>Open the PR without a changelog file, see what number you got, and <em>then</em>
|
||
add the changelog file to your branch, or:</p>
|
||
</li>
|
||
<li>
|
||
<p>Look at the <a href="https://github.com/element-hq/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>
|
||
<p><a href="https://github.com/richvdh/scripts/blob/master/next_github_number.sh">This
|
||
script</a>
|
||
might be helpful if you find yourself doing this a lot.</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>
|
||
<h2 id="sign-off"><a class="header" href="#sign-off">Sign off</a></h2>
|
||
<p>After you make a PR a comment from @CLAassistant will appear asking you to sign
|
||
the <a href="https://cla-assistant.io/element-hq/synapse">CLA</a>.
|
||
This will link a page to allow you to confirm that you have read and agreed to
|
||
the CLA by signing in with GitHub.</p>
|
||
<p>Alternatively, you can sign off before opening a PR by going to
|
||
<a href="https://cla-assistant.io/element-hq/synapse">https://cla-assistant.io/element-hq/synapse</a>.</p>
|
||
<p>We accept contributions under a legally identifiable name, such as
|
||
your name on government documentation or common-law names (names
|
||
claimed by legitimate usage or repute). Unfortunately, we cannot
|
||
accept anonymous contributions at this time.</p>

|
||
<p>Once the Pull Request is opened, you will see a few things:</p>
|
||
<ol>
|
||
<li>our automated CI (Continuous Integration) pipeline will run (again) the linters, the unit tests, the integration tests and more;</li>
|
||
<li>one or more of the developers will take a look at your Pull Request and offer feedback.</li>
|
||
</ol>
|
||
<p>From this point, you should:</p>
|
||
<ol>
|
||
<li>Look at the results of the CI pipeline.
|
||
<ul>
|
||
<li>If there is any error, fix the error.</li>
|
||
</ul>
|
||
</li>
|
||
<li>If a developer has requested changes, make these changes and let us know if it is ready for a developer to review again.
|
||
<ul>
|
||
<li>A pull request is a conversation, if you disagree with the suggestions, please respond and discuss it.</li>
|
||
</ul>
|
||
</li>
|
||
<li>Create a new commit with the changes.
|
||
<ul>
|
||
<li>Please do NOT overwrite the history. New commits make the reviewer’s life easier.</li>
|
||
<li>Push this commits to your Pull Request.</li>
|
||
</ul>
|
||
</li>
|
||
<li>Back to 1.</li>
|
||
<li>Once the pull request is ready for review again please re-request review from whichever developer did your initial
|
||
review (or leave a comment in the pull request that you believe all required changes have been done).</li>
|
||
</ol>
|
||
<p>Once both the CI and the developers are happy, the patch will be merged into Synapse and released shortly!</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
|
||
please get involved - and we hope you have as much fun hacking on Matrix as we
|
||
do!</p>
