If you don’t already have Git set up:
git config --global user.name "<your real name>" git config --global user.email "<your email>"
This is directly lifted from the work of Ciaran McCreesh and can be found in its original form on his blog. This will be updated to match changes there as possible.
Repositories are configured as normal, with their
sync set to point to the usual remote location. The location is specified in
/etc/paludis/repositories/<repo>.conf like this:
sync = git+https://git.exherbo.org/<repo>.git
To contribute on a repository, first fork it and pull a local clone. Fork these repositories on our Gitlab instance to easily push your contributions. In the following explanation we will use arbor, but it works with any repository.
Now that we have a local clone of the fork in
sync = git://git.exherbo.org/arbor.git local: git+file:///home/users/ciaranm/repos/arbor
Normally, when you sync, you’ll be syncing against upstream. To sync with the local clone:
cave sync -s local arbor
The workflow now is: - Update the local copy of your personal repository to be in sync with upstream. It possibly saves you from rebasing your work on changes that happened in the meantime. Or even worse, somebody might already have done the exact same thing. - Work locally on your changes until everything works. The package should resolve fine on your system. - Use the wonders of
git rebase -i to tidy up your work into nice friendly pushable commits.
Some things to note:
git commit --fixup <commit-id>for easier commit squashing.
git rebase -i --autosquashif you used
fixupcommits into the commits they’re fixing.
sync_optionstoo, if you need it. Thus, for branches, you can use
sync_options = --branch=branch-on-upstream local: --branch=my-local-branch
cave sync -s local <repo> -r <commit-id>. You don’t have to supply the full commit-id, you only need to provide at least the first 4 characters. Also keep in mind that when you amend a commit its commit-id changes, if you keep using the old commit-id you’ll sync the old version of that commit.
Configure your git author name and email properly. Use your real name. See
man git-config, look for
Generate your patches using
git format-patch, from local commits. If your patch renames files, please use the options
-M -C -C to
git format-patch, to detect copies and renames. This makes the resulting patch much easier to read. Alternatively, you can enable
-M -C by default by running
git config --global diff.renames copy. See
clear and descriptive commit message, explaining the change.
short one line summary, followed by an
empty line, and, as you see fit, a more
elaborate description of your changes
Version bump is not an acceptable commit message. You should at least mention the package and version you’re adding. Try running
git log --oneline on a repository full of
Version bump commits and you’ll understand why.
In case you’re making non-obvious changes, consider explaining the reasoning behind the changes.
If you rearrange code or make white space and style changes then avoid making real changes in the same commit. Put the actual changes you do in a separate commit. This makes it easier to review as well as allowing git to track the history of the affected code properly.
Do make references to relevant bug reports, mailing lists, … where appropriate.
Exhereses use 4 spaces and strictly no tabs for indentation. Run your patch through
--check, to verify that it doesn’t introduce whitespace errors.
app-emacs/exheres-mode will highlight common exheres syntax errors. Use them.
When submitting a new package, first consider whether it’s really important enough to be in the official repositories, or whether you should instead put it in your own supplemental repository. If the quality of your supplemental repository is reasonably high, host it somewhere (preferably on our Gitlab instance), and we’ll consider adding it to the unavailable-unofficial repository.
Do submit original work. Don’t blindly copy ebuilds, adjusting for differences between ebuilds and exhereses. If you need to install a package, there is a tool far more suitable that you can use instead of blindly adapting ebuilds to exheres.
Don’t try to bump large and critical packages (e.g gcc, X, grub…) on your own without speaking to their maintainers. Bumping such packages takes some time and requires extra testing, so please be patient.
Sometimes patching upstream sources is unavoidable. If you do apply patches, make sure they’re properly documented according to our patches policy, found in exheres-for-smarties. Always consider that adding patches that will not be accepted upstream means you get to maintain those.
To be included in any of our repositories, contributions must be licenced under the GPL-2. Add an appropriate copyright notice if your contributions to a given file warrant it. See exheres-for-smarties.
If you have your own repository and its quality is fairly high, you should submit it for review so it will be included in unavailable-unofficial. To do that, just add it to our infra-scripts git repository as in this example and push it to Gitlab.
This way, others will not duplicate any work you may have done, and you will get helpful tips on how to improve your packaging skills. Also, this will allow others to more easily contribute to your packages or point out bugs. See kloeri’s blog post if you are not yet convinced.
We expect a decent level of responsiveness from you and we reserve the right to remove repositories with broken packages if you do not respond to patches and inquiries within a reasonable amount of time (Rule of thumb: within 30 days).
More concretely, if there’s a patch for your repository for 30 days or more, we will consider your repository for removal from unavailable-unofficial. You’ll get up to two additonal “wake-up calls” before the actual removal, though. If you’re not on IRC, we’ll send you an email to your last known address (so make sure to use a valid, working email address in your exheres, etc.).
This is not about “punishing” you or something like that but to ensure that the repositories in unavailable-unofficial are maintained according to Exherbo’s quality standards.
Remember that it is trivial to have your repository re-added once it is fixed up/maintained properly again.
To have fancy IRC commit notifications, please consider using our push hook. We currently support GitHub, Gitorious and self-hosted repositories. Ask any Exherbo developer on IRC to get the WebHook URL.
