How to create patches? [message #491825]

I made a one line change and am create and submit a patch into Bugzilla
but I don't even know how to start. According to the documentation, I'm
supposed to just invoke 'git diff' (or at least, I think that's what I'm
supposed to do). This is good, I get a diff, but the documentation also
mentions something about providing a commit message. How does that come
into play? My only experience with distributed SCM systems is cloning a
bzr repository (and now a git one) so I really don't know what I'm
supposed to do.

Chris's patch doesn't seem to have any commit messages as far as I can
see, it seems like a regular old CVS diff to me.

Any pointers would be much appreciated.

Thanks,
Remy

Find detailed instructions for contribution here.

You may either directly push your change from git to Gerrit for review as described in the contributor guide.

Alternatively you may run "git format-patch" on the git branch you developed your patch on and attach the resulting file
as a patch into Bugzilla. See an example here. This way your git commit message will be transferred from git into the
patch file. Bugzilla also knows how to extract the diff from such attachments, see an example here.

Yeah, I tried reading that before posting but it didn't make a lot of
sense to me. Could be just me or it could be because I've never used a
decentralized SCM system, oh well.

What I ended up doing was committing through the EGit interface and then
using 'git format-patch --root'. I have attached my simple patch to
Bugzilla in the mean time. It looks right based on the other attachments
I've seen attached to Bugzilla but I could be wrong. :|

--root wasn't necessary for 1 commit. I think you wanted 'git
format-patch -1' to make it format the most recent commit on the current
branch.

Thanks, applied. I adjusted the commit message a bit to better fit with
standard git conventions, but otherwise the patch was correct.
