NB! If you're behind a corporate wall with http only access to the
world, you can still use these instructions!

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

- On subsequent sign ins, use the full URL prefaced with 'http://'
  For example:

	http://user_identifier.open_id_provider.com

0.1. Add a username to your profile.

After creating the Gerrit account and signing in, you will need to
add a username to your profile. To do this, go to 'Settings', and
add a username of your choice.

Your username will be required in step 2 and substituted wherever
the string 'USERNAME' is found.

0.2. Add an SSH public key

Following the directions for your specific platform:

	for Windows: help.github.com/win-set-up-git/#_set_up_ssh_keys
	for OSX:     help.github.com/mac-set-up-git/#_set_up_ssh_keys
	for Linux:   help.github.com/linux-set-up-git/#_set_up_ssh_keys

While these pages describe the setting up of git as well,
you should scroll down the page till you get to the section:
'Next: Set Up SSH Keys', and follow the steps described.

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

Or with http only:

git remote add review http://openocd.zylin.com/p/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/

Or with http only:

wget http://openocd.zylin.com/tools/hooks/commit-msg
mv commit-msg .git/hooks
chmod +x .git/hooks/commit-msg

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
