Checklist (and a short version for the impatient):
+ Commits:
+
- make commits of logical units
- check for unnecessary whitespace with "git diff --check"
before committing
- the first line of the commit message should be a short
description and should skip the full stop
- if you want your work included in git.git, add a
- "Signed-off-by: Your Name <your@email.com>" line to the
+ "Signed-off-by: Your Name <you@example.com>" line to the
commit message (or just use the option "-s" when
committing) to confirm that you agree to the Developer's
Certificate of Origin
- - do not PGP sign your patch
+ - make sure that you have tests for the bug you are fixing
+ - make sure that the test suite passes after your commit
+
+ Patch:
+
- use "git format-patch -M" to create the patch
+ - do not PGP sign your patch
- do not attach your patch, but read in the mail
body, unless you cannot teach your mailer to
leave the formatting of the patch alone.
corrupt whitespaces.
- provide additional information (which is unsuitable for
the commit message) between the "---" and the diffstat
- - send the patch to the list _and_ the maintainer
- if you change, add, or remove a command line option or
make some other user interface change, the associated
documentation should be updated as well.
+ - if your name is not writable in ASCII, make sure that
+ you send off a message in the correct encoding.
+ - send the patch to the list (git@vger.kernel.org) and the
+ maintainer (gitster@pobox.com) if (and only if) the patch
+ is ready for inclusion. If you use git-send-email(1),
+ please test it first by sending email to yourself.
Long version:
run git diff --check on your changes before you commit.
+(1a) Try to be nice to older C compilers
+
+We try to support wide range of C compilers to compile
+git with. That means that you should not use C99 initializers, even
+if a lot of compilers grok it.
+
+Also, variables have to be declared at the beginning of the block
+(you can check this with gcc, using the -Wdeclaration-after-statement
+option).
+
+Another thing: NULL pointers shall be written as NULL, not as 0.

(2) Generate your patch using git tools out of your commits.
git based diff tools (git, Cogito, and StGIT included) generate
It is a common convention to prefix your subject line with
[PATCH]. This lets people easily distinguish patches from other

+the closing bracket to mark the nature of the patch is also
+encouraged. E.g. [PATCH/RFC] is often used when the patch is
+not ready to be applied but it is for discussion, [PATCH v2],
+[PATCH v3] etc. are often seen when you are sending an update to
+what you have previously sent.
"git format-patch" command follows the best current practice to
format the body of an e-mail message. At the beginning of the
on the git mailing list. If your patch is for discussion first,
send it "To:" the mailing list, and optionally "cc:" him. If it
is trivially correct or after the list reached a consensus, send

-point out some special detail about the sign-off.
+Notice that you can place your own Signed-off-by: line when
+forwarding somebody else's patch with the above rules for
+D-C-O. Indeed you are encouraged to do so. Do not forget to

+------------------------------------------------
+An ideal patch flow
+
+Here is an ideal patch flow for this project the current maintainer
+suggests to the contributors:
+
+ (0) You come up with an itch. You code it up.
+
+ (1) Send it to the list and cc people who may need to know about
+ the change.
+
+ The people who may need to know are the ones whose code you
+ are butchering. These people happen to be the ones who are
+ most likely to be knowledgeable enough to help you, but
+ they have no obligation to help you (i.e. you ask for help,
+ don't demand). "git log -p -- $area_you_are_modifying" would
+ help you find out who they are.
+
+ (2) You get comments and suggestions for improvements. You may
+ even get them in a "on top of your change" patch form.
+
+ (3) Polish, refine, and re-send to the list and the people who
+ spend their time to improve your patch. Go back to step (2).
+
+ (4) The list forms consensus that the last round of your patch is
+ good. Send it to the list and cc the maintainer.
+
+ (5) A topic branch is created with the patch and is merged to 'next',
+ and cooked further and eventually graduates to 'master'.
+
+In any time between the (2)-(3) cycle, the maintainer may pick it up
+from the list and queue it to 'pu', in order to make it easier for
+people play with it without having to pick up and apply the patch to
+their trees themselves.
