openocd/HACKING

Submitting patches to the OpenOCD Gerrit server:

OpenOCD is to some extent a "self service" open source project, so to
contribute, you must follow the standard procedures to have the best
possible chance to get your changes accepted.

The procedure to create a patch is essentially:

- make the changes
- create a commit
- send the changes to the Gerrit server for review
- correct the patch and re-send it according to review feedback
 

0. Create a Gerrit account at:

http://openocd.zylin.com

1. Clone the git repository, rather than just
download the source. 

git clone git://openocd.git.sourceforge.net/gitroot/openocd/openocd

or if you have problems with the "git:" protocol, use
the slower http protocol:

git clone http://repo.or.cz/r/openocd.git

2. Set up Gerrit with your local repository. All this does it
to instruct git locally how to send off the changes.

Add a new remote to git using Gerrit username:

git remote add review ssh://USERNAME@openocd.zylin.com:29418/openocd.git
git config remote.review.push HEAD:refs/for/master

You will need to install this hook, we will look into a better
solution:

scp -p -P 29418 USERNAME@openocd.zylin.com:hooks/commit-msg .git/hooks/

3. Set up git with your name and email:

git config --global user.name "John Smith"
git config --global user.email "john@smith.org"

4. Work on your patches. Split the work into 
multiple small patches that can be reviewed and
applied seperately and safely to the OpenOCD
repository.

while(!done) {
  work - edit files using your favorite editor.
  run "git commit -s -a" to commit all changes. 
}

TIP! use "git add ." before commit to add new files.

--- example comment, notice the short first line w/topic ---
topic: short comment
<blank line>
longer comments over several
lines...
-----

5. Next you need to make sure that your patches
are on top of the latest stuff on the server and
that there are no conflicts.

git pull --rebase origin/master

6. Send the patches to the Gerrit server for review.

git push review

7. Forgot something, want to add more? Just make the changes and do:

git commit --amend
git push review
