Here, by way of an arbitrary example, is the top of <code>git log --graph b2dba0607</code>:</p> +<img src="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="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="#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="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="#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="#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> +<hr /> +<p><b id="f1">[1]</b>: “Squash and merge” is GitHub's term for this +operation.
