The 'git clone' command in development.pod doesn't actually work. This corrects the syntax. Signed-off-by: Ask Bjørn Hansen <ask@develooper.com>

=head1 Developing Qpsmtpd
|
|
|
|
=head2 Mailing List
|
|
|
|
All qpsmtpd development happens on the qpsmtpd mailing list.
|
|
|
|
Subscribe by sending mail to qpsmtpd-subscribe@perl.org
|
|
|
|
=head2 Git
|
|
|
|
We use git for version control.
|
|
|
|
Ask owns the master repository at git://github.com/abh/qpsmtpd.git
|
|
|
|
We suggest using github to host your repository -- it makes your
|
|
changes easily accessible for pulling into the master. After you
|
|
create a github account, go to
|
|
http://github.com/abh/qpsmtpd/tree/master and click on the "fork"
|
|
button to get your own repository.
|
|
|
|
=head3 Making a working Copy
|
|
|
|
git clone git@github.com:username/qpsmtpd.git qpsmtpd
|
|
|
|
will check out your copy into a directory called qpsmtpd
|
|
|
|
=head3 Making a branch for your change
|
|
|
|
As a general rule, you'll be better off if you do your changes on a
|
|
branch - preferably a branch per unrelated change.
|
|
|
|
You can use the C<git branch> command to see which branch you are on.
|
|
|
|
The easiest way to make a new branch is
|
|
|
|
git checkout -b topic/my-great-change
|
|
|
|
This will create a new branch with the name "topic/my-great-change"
|
|
(and your current commit as the starting point).
|
|
|
|
=head3 Committing a change
|
|
|
|
Edit the appropriate files, and be sure to run the test suite.
|
|
|
|
emacs lib/Qpsmtpd.pm # for example
|
|
perl Makefile.PL
|
|
make test
|
|
|
|
When you're ready to check it in...
|
|
|
|
git add lib/Qpsmtpd.pm # to let git know you changed the file
|
|
git add --patch plugin/tls # interactive choose which changes to add
|
|
git diff --cached # review changes added
|
|
git commit
|
|
git log -p # review your commit a last time
|
|
git push origin # to send to github
|
|
|
|
=head3 Submit patches by mail
|
|
|
|
If you don't use github, or if you want to submit your patch to the
|
|
mailing list for review (often a good idea), you can use
|
|
|
|
git format-patch
|
|
|
|
to generate "patch files". For example "git format-patch HEAD~3" will
|
|
give you three files with the last changes.
|
|
|
|
Then use "git send-email" to send them to the mailing list for review.
|
|
|
|
=head3 Merging changes back in from the master repository
|
|
|
|
Tell git about the master repository. We're going to call it 'abh'
|
|
for now, but you could call it anything you want. You only have to do
|
|
this once.
|
|
|
|
git remote add abh git://github.com/abh/qpsmtpd.git
|
|
|
|
Pull in data from all remote branches
|
|
|
|
git remote update
|
|
|
|
Forward-port local commits to the updated upstream head
|
|
|
|
git rebase abh/master
|
|
|
|
If you have a change that conflicts with an upstream change (git will
|
|
let you know) you have two options.
|
|
|
|
Manually fix the conflict and then do
|
|
|
|
git add some/file
|
|
git commit
|
|
|
|
Or if the conflicting upstream commit did the same logical change then
|
|
you might want to just skip the local change:
|
|
|
|
git rebase --skip
|
|
|
|
Be sure to decide whether you're going to skip before you merge, or
|
|
you might get yourself into an odd situation.
|
|
|
|
Conflicts happen because upstream committers may make minor tweaks to
|
|
your change before applying it.
|
|
|
|
=head3 Throwing away changes
|
|
|
|
If you get your working copy into a state you don't like, you can
|
|
always revert to the last commit:
|
|
|
|
git reset --hard HEAD
|
|
|
|
Or throw away your most recent commit:
|
|
|
|
git reset --hard HEAD^
|
|
|
|
If you make a mistake with this, git is pretty good about keeping your
|
|
commits around even as you merge, rebase and reset away. This log of
|
|
your git changes is called with "git reflog".
|
|
|
|
=head3 Applying other peoples changes
|
|
|
|
If you get a change in an email with the patch, one easy way to apply
|
|
other peoples changes is to use C<git am>. That will go ahead and
|
|
commit the change. To modify it, you can use C<git commit --amend>.
|
|
|
|
If the changes are in a repository, you can add that repository with
|
|
"git remote add" and then either merge them in with "git merge" or
|
|
pick just the relevant commits with "git cherry-pick".
