 | |
| <p>Everyone is welcome to contribute code to <a href="https://github.com/matrix-org">matrix.org
 | |
| projects</a>, provided that they are willing to
 | |
| license their contributions under the same license as the project itself. We
 | |
| follow a simple 'inbound=outbound' model for contributions: the act of
 | |
| submitting an 'inbound' contribution means that the contributor agrees to
 | |
| license the code under the same terms as the project's overall 'outbound'
 | |
| license - in our case, this is almost always Apache Software License v2 (see
 | |
| <a href="LICENSE">LICENSE</a>).</p>
 | |
| <h1 id="2-what-do-i-need"><a class="header" href="#2-what-do-i-need">2. What do I need?</a></h1>
 | |
| <p>The code of Synapse is written in Python 3. To do pretty much anything, you'll need <a href="https://wiki.python.org/moin/BeginnersGuide/Download">a recent version of Python 3</a>.</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
 | |

 | |
| it, including the conventions for the <a href="docs/code_style.html#configuration-file-format">sample configuration
 | |

 | |
| <p>There is a growing amount of documentation located in the <a href="docs">docs</a>
 | |
| directory. This documentation is intended primarily for sysadmins running their
 | |
| own Synapse instance, as well as developers interacting externally with
 | |
| Synapse. <a href="docs/dev">docs/dev</a> exists primarily to house documentation for
 | |
| Synapse developers. <a href="docs/admin_api">docs/admin_api</a> houses documentation
 | |
| regarding Synapse's Admin API, which is used mostly by sysadmins and external
 | |
| service developers.</p>
 | |
| <p>If you add new files added to either of these folders, please use <a href="https://guides.github.com/features/mastering-markdown/">GitHub-Flavoured

 | |

 | |
| <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>They're pretty fast, don't hesitate!</p>
 | |
| <pre><code class="language-sh">source ./env/bin/activate
 | |
| ./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">source ./env/bin/activate
 | |
| ./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">source ./env/bin/activate
 | |
| ./scripts-dev/lint.sh path/to/file1.py path/to/file2.py path/to/folder
 | |
| </code></pre>
 | |
| <h2 id="run-the-unit-tests"><a class="header" href="#run-the-unit-tests">Run the unit tests.</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">source ./env/bin/activate
 | |
| trial 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">source ./env/bin/activate
 | |
| 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 trial tests
 | |
| </code></pre>
 | |
| <h2 id="run-the-integration-tests"><a class="header" href="#run-the-integration-tests">Run the integration tests.</a></h2>
 | |
| <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:py37
 | |
| </code></pre>
 | |
| <p>This configuration should generally cover  your needs. For more details about other configurations, see <a href="https://github.com/matrix-org/sytest/blob/develop/docker/README.md">documentation in the SyTest repo</a>.</p>
 | |
| <h1 id="9-submit-your-patch"><a class="header" href="#9-submit-your-patch">9. Submit your patch.</a></h1>
 | |
| <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="#test-test-test">all the tests pass</a>, including the coding style;</li>
 | |
| <li><a href="#sign-off">sign off</a> your contribution;</li>
 | |
| <li><code>git push</code> your commit to your fork of Synapse;</li>
 | |
| <li>on GitHub, <a href="https://docs.github.com/en/github/collaborating-with-issues-and-pull-requests/creating-a-pull-request">create the Pull Request</a>;</li>
 | |
| <li>add a <a href="#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>
 | |
| </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="#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>
 | |
| <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>
