We document that a commit fixing an issue tracked in GitLab should put just "Fixes: #NNN" into its commit message. But when viewing git log, having full URL which is directly clickable is more developer friendly and GitLab is capable of handling both. Therefore, document that users should put full URL, just like when fixing a bug tracked in other sites.

Best practices
|
|
==============
|
|
|
|
These are a few guidelines to keep in mind when submitting patches
|
|
to libvirt: following them will maximise the chance of your patches
|
|
being reviewed in a timely manner and being accepted into libvirt
|
|
with minimal back-and-forth.
|
|
|
|
- Discuss any large changes on the mailing list first. Post
|
|
patches early and listen to feedback.
|
|
|
|
- In your commit message, make the summary line reasonably short
|
|
(60 characters is typical), followed by a blank line, followed
|
|
by any longer description of why your patch makes sense. If the
|
|
patch fixes a regression, and you know what commit introduced
|
|
the problem, mentioning that is useful. If the patch resolves
|
|
an upstream bug reported in GitLab, or downstream bug, put
|
|
"Resolves: $fullURL" of the bug. In both cases also summarize
|
|
the issue rather than making all readers follow the link. You
|
|
can use 'git shortlog -30' to get an idea of typical summary
|
|
lines.
|
|
|
|
- Split large changes into a series of smaller patches,
|
|
self-contained if possible, with an explanation of each patch
|
|
and an explanation of how the sequence of patches fits
|
|
together. Moreover, please keep in mind that it's required to
|
|
be able to compile cleanly (**including** ``ninja test``) after
|
|
each patch. A feature does not have to work until the end of a
|
|
series, but intermediate patches must compile and not cause
|
|
test-suite failures (this is to preserve the usefulness of
|
|
``git bisect``, among other things).
|

There is more on this subject, including lots of links to
|
|
background reading on the subject, on `Richard Jones' guide to
|
|
working with open source

projects <https://people.redhat.com/rjones/how-to-supply-code-to-open-source-projects/>`__.
