This How-To is about the Git repository in Titanium Linux.
You will find here useful examples on how to use git in TLD.
Ready? Let's start.

You need to be a developer to do some of these things.

I. How do I commit a new .spec file or package to the repository?

1) Clone an empty repository

git clone git@git.tld-linux.org:packages/your_new_package

2) Set your local Email address

cd your_new_repo
git config --local user.email your_git_login@tld-linux.org

This step allows you to later push your changes to the server. If you skip this step, your push will fail due to a server-side-hook.

3) Put your files into the repository and locally add them

<put your files in here>
git add file1 file2 files*
git commit

4) Push your changes to the server

git push origin master

If you push your changes for the first time of the repositorys "life", you'll need to add the origin to it.
After that you'll be fine doing just:

git push

NOTE:
It is possible to shorten these commands ex. git add and git commit can be put together into: git commit -a.
You can commit several time into you local repository before pushing. You don't need to push each time you commit.

II. Crap, I've checked out a repository, forgot to change the local Email address and commited my changes. Now I can't push them to the server. What can I do?

This is very unfortunate. Afaik you've got only 2 options.

1) Delete your commit. This means all of your changes will be lost, but you can store them elsewhere for the time being, right?
To do this (after you backed up your changes) type:

git reset --hard HEAD~1

the HEAD~1 option tells git to go 1 commit back in the history. Now set your local Email address, put back your changes and commit again. Push should now work as expected.

2) The second way is to remove locally your repository and re-clone it. Then put back your changes to it, commit and push.

III. My new repository didn't show up on the web.

THIS IS FOR git-admins ONLY

ssh your_git_login@kraz.tld-linux.org
sudo su -
su - git
./scripts/packages_enable_gitweb.sh

That's it. Maybe this will get automated some time.
