If you are +looking for general contribution guidelines, please look at the [general +contribution guidelines](./CONTRIBUTING.md). + +All changes are tracked at [cl.tvl.fyi](https://cl.tvl.fyi) using Gerrit. See +[Registration](#registration) for information on how to register an account. + +## Gerrit setup + +Gerrit uses the concept of change IDs to track commits across rebases and other +operations that might change their hashes, and link them to unique changes in +Gerrit. + +To make this process smooth for users, the repository should be cloned and a +commit hook should be installed as follows: + +``` +git clone "ssh://$USER@code.tvl.fyi:29418/depot" +scp -p -P 29418 $USER@code.tvl.fyi:hooks/commit-msg "depot/.git/hooks/" +``` + +If you have a previous clone of the depot via HTTP you can use `git remote +set-url` to update the origin URL and install the hook in the same way as above. + +## Gerrit workflows + +The developer workflow on Gerrit is quite different from what GitHub-users are +used to. + +The depot does not have branches (other than Gerrit's internal metadata refs) +and all development happens at `HEAD`. + +Every time you create a new commit the change hook will insert a unique +`Change-Id` tag into the commit message. Once you are satisfied with the state +of your commit and want to submit it for review, you push it to a git ref called +`refs/for/master`. This designates the commits as changelists (CLs) targeted for +the `master` branch. + +``` +Example: +git commit -m 'docs(REVIEWS): Fixed all the errors in the reviews docs' +git push origin HEAD:refs/for/master +``` + +TIP: Every individual commit will become a separate change. We do not merge +related commits, but instead submit them one by one. Be aware that if you are +expecting a different behaviour and attempt something like an unsquashed subtree +merge, you will produce a *lot* of CLs. This is strongly discouraged. + +During your review, the reviewer(s) might ask you to make changes. You can +simply amend your commit(s) and push to the same ref. Gerrit will automatically +update your changes. + +Read more about the Gerrit workflow in the [Gerrit walkthrough][]. + +## Review process & approvals + +Each user has the ability to create their own users directory in +`//users/<username>` in which they can submit code without review from other +contributors (they will still need to +2 their own changes, and the initial +check-in of the `OWNERS` file needs to be reviewed). + +You can set a directory like this up for yourself by proposing a change similar +to [CL/246](https://cl.tvl.fyi/c/depot/+/246). + +For all paths outside of `//users`, code review is required. We have no strict +guidelines about the review process itself, as we're not a megacorp, but we have +formalised checks before submitting: + +* At least one person who is [an owner][OWNERS] of the codepath must have given + a +2 review +* The commit message must conform to our [guidelines][] +* No code review comments must be left unresolved + +If all these conditions are fulfilled, the **change author submits their change +themselves**. + +## Registration + +If you would like to have an account on the Gerrit instance, follow these +instructions: + +1. Be a member of `##tvl`. +2. Clone the depot locally. +3. Create a user entry in our LDAP server, in [`contents.ldif`][]. You create + your password hash by using `slappasswd`, which ships in the `openldap` + package on most distributions. + + On systems with Nix systems you can use `nix-shell -p openldap` to get access + to the command. +4. Create a commit adding yourself (see e.g. + [CL/223](https://cl.tvl.fyi/c/depot/+/223)). +5. Submit the commit via email (see below). + +## Submitting changes via email + +You can submit a patch via email to `depot@tazj.in` and it will be added to +Gerrit by a contributor. + +Create an appropriate commit locally and send it us using either of these options: + +* `git format-patch`: This will create a `.patch` file which you should email to + us. +* `git send-email`: If configured on your system, this will take care of the + whole emailing process for you. + +The email address is a [public group][]. + +[Gerrit walkthrough]: https://gerrit-review.googlesource.com/Documentation/intro-gerrit-walkthrough.html +[OWNERS]: https://cl.tvl.fyi/plugins/owners/Documentation/config.md +[guidelines]: ./CONTRIBUTING.md#commit-messages +[`contents.ldif`]: https://code.tvl.fyi/tree/ops/nixos/tvl-slapd/contents.ldif +[public group]: https://groups.google.com/a/tazj.in/forum/?hl=en#!forum/depot |
