Not that I have stricter patch submission standard than ordinary projects, I wanted to have it to make sure people understand what they are doing when they add their own Signed-off-by line. Signed-off-by: Junio C Hamano <junkio@cox.net>

I started reading over the SubmittingPatches document for Linux
|
|
kernel, primarily because I wanted to have a document similar to
|
|
it for the core GIT to make sure people understand what they are
|
|
doing when they write "Signed-off-by" line.
|
|
|
|
But the patch submission requirements are a lot more relaxed
|
|
here, because the core GIT is thousand times smaller ;-). So
|
|
here is only the relevant bits.
|
|
|
|
|
|
(1) Make separate commits for logically separate changes.
|
|
|
|
Unless your patch is really trivial, you should not be sending
|
|
out a patch that was generated between your working tree and
|
|
your commit head. Instead, always make a commit with complete
|
|
commit message and generate a series of patches from your
|
|
repository. It is a good discipline.
|
|
|
|
Describe the technical detail of the change(s).
|
|
|
|
If your description starts to get long, that's a sign that you
|
|
probably need to split up your commit to finer grained pieces.
|
|
|
|
|
|
(2) Generate your patch using git/cogito out of your commits.
|
|
|
|
git diff tools generate unidiff which is the preferred format.
|
|
You do not have to be afraid to use -M option to "git diff" or
|
|
"git format-patch", if your patch involves file renames. The
|
|
receiving end can handle them just fine.
|
|
|
|
Please make sure your patch does not include any extra files
|
|
which do not belong in a patch submission. Make sure to review
|
|
your patch after generating it, to ensure accuracy. Before
|
|
sending out, please make sure it cleanly applies to the "master"
|
|
branch head.
|
|
|
|
|
|
(3) Sending your patches.
|
|
|
|
People on the git mailing list needs to be able to read and
|
|
comment on the changes you are submitting. It is important for
|
|
a developer to be able to "quote" your changes, using standard
|
|
e-mail tools, so that they may comment on specific portions of
|
|
your code. For this reason, all patches should be submitting
|
|
e-mail "inline". WARNING: Be wary of your MUAs word-wrap
|
|
corrupting your patch. Do not cut-n-paste your patch.
|
|
|
|
It is common convention to prefix your subject line with
|
|
[PATCH]. This lets people easily distinguish patches from other
|
|
e-mail discussions.
|
|
|
|
"git format-patch" command follows the best current practice to
|
|
format the body of an e-mail message. At the beginning of the
|
|
patch should come your commit message, ending with the
|
|
Signed-off-by: lines, and a line that consists of three dashes,
|
|
followed by the diffstat information and the patch itself. If
|
|
you are forwarding a patch from somebody else, optionally, at
|
|
the beginning of the e-mail message just before the commit
|
|
message starts, you can put a "From: " line to name that person.
|
|
|
|
You often want to add additional explanation about the patch,
|
|
other than the commit message itself. Place such "cover letter"
|
|
material between the three dash lines and the diffstat.
|
|
|
|
Do not attach the patch as a MIME attachment, compressed or not.
|
|
Do not let your e-mail client send quoted-printable. Many
|
|
popular e-mail applications will not always transmit a MIME
|
|
attachment as plain text, making it impossible to comment on
|
|
your code. A MIME attachment also takes a bit more time to
|
|
process. This does not decrease the likelihood of your
|
|
MIME-attached change being accepted, but it makes it more likely
|
|
that it will be postponed.
|
|
|
|
Exception: If your mailer is mangling patches then someone may ask
|
|
you to re-send them using MIME.
|
|
|
|
Note that your maintainer does not subscribe to the git mailing
|
|
list (he reads it via mail-to-news gateway). If your patch is
|
|
for discussion first, send it "To:" the mailing list, and
|
|
optoinally "cc:" him. If it is trivially correct or after list
|
|
discussion reached consensus, send it "To:" the maintainer and
|
|
optionally "cc:" the list.
|
|
|
|
|
|
(6) Sign your work
|
|
|
|
To improve tracking of who did what, we've borrowed the
|
|
"sign-off" procedure from the Linux kernel project on patches
|
|
that are being emailed around. Although core GIT is a lot
|
|
smaller project it is a good discipline to follow it.
|
|
|
|
The sign-off is a simple line at the end of the explanation for
|
|
the patch, which certifies that you wrote it or otherwise have
|
|
the right to pass it on as a open-source patch. The rules are
|
|
pretty simple: if you can certify the below:
|
|
|
|
Developer's Certificate of Origin 1.1
|
|
|
|
By making a contribution to this project, I certify that:
|
|
|
|
(a) The contribution was created in whole or in part by me and I
|
|
have the right to submit it under the open source license
|
|
indicated in the file; or
|
|
|
|
(b) The contribution is based upon previous work that, to the best
|
|
of my knowledge, is covered under an appropriate open source
|
|
license and I have the right under that license to submit that
|
|
work with modifications, whether created in whole or in part
|
|
by me, under the same open source license (unless I am
|
|
permitted to submit under a different license), as indicated
|
|
in the file; or
|
|
|
|
(c) The contribution was provided directly to me by some other
|
|
person who certified (a), (b) or (c) and I have not modified
|
|
it.
|
|
|
|
(d) I understand and agree that this project and the contribution
|
|
are public and that a record of the contribution (including all
|
|
personal information I submit with it, including my sign-off) is
|
|
maintained indefinitely and may be redistributed consistent with
|
|
this project or the open source license(s) involved.
|
|
|
|
then you just add a line saying
|
|
|
|
Signed-off-by: Random J Developer <random@developer.example.org>
|
|
|
|
Some people also put extra tags at the end. They'll just be ignored for
|
|
now, but you can do this to mark internal company procedures or just
|
|
point out some special detail about the sign-off.
