=== Environment variables ===
These are some environment variables that git uses when you commit changes. It's best to set these environment variables so that git doesn't rely on your system's username or hostname. Place this snippet in your ~/.bashrc configuration file.
{{{
# Git variables
export GIT_AUTHOR_NAME='<your name>'
export GIT_AUTHOR_EMAIL='<your email>'
export GIT_COMMITTER_NAME='<your name>'
export GIT_COMMITTER_EMAIL='<your email>'
}}}

Git

The repositories for the packaging in git is stored in a different manner than they are under svn. Each package has its own git repository (and thus its own directory) under the /git/pkg-games directory on the alioth servers.

This guide assumes that you are uploading the packaging files for a package for the first time.

A separate section will describe how to import the packaging that was stored in the svn repository in the future.

Environment variables

These are some environment variables that git uses when you commit changes. It's best to set these environment variables so that git doesn't rely on your system's username or hostname. Place this snippet in your ~/.bashrc configuration file.

# Git variables
export GIT_AUTHOR_NAME='<your name>'
export GIT_AUTHOR_EMAIL='<your email>'
export GIT_COMMITTER_NAME='<your name>'
export GIT_COMMITTER_EMAIL='<your email>'

Creating a git repository

First, create a repository in the /git/pkg-games directory on the alioth servers.

$ mkdir <package>.git
$ cd <package>.git
$ git --bare init --shared

Now edit the 'description' file in the directory you just created to one that is appropriate for the package.

$ echo "Packaging for <package>" >description

Let's also enable the use of 'hooks/post-update'.

$ chmod a+x hooks/post-update

Now we're done creating a repository for the package. You could also use the 'setup-repository' script that's in the pkg-games directory. That script is really a symlink to the script that's used in the collab-maint directory.

./setup-repository <package> '<package description>'

Uploading a package to the repository

Now let's import the package into a git repository. This is easy using 'git-import-dsc' from the 'git-buildpackage' package.

$ git-import-dsc --pristine-tar <package>.dsc

(The --pristine-tar option is optional; if you have pristine-tar installed this will store enough information in the git repository to reproduce the pristine upstream tarball later.)

A directory with the name of the source package should have been made. Change into that directory.

$ cd <package>

Ensure the tags that are created reflect if a package has been released. git-buildpackage creates tags for the debian branch and the upstream branch. If the tag created for the debian branch reflects an unreleased version, you'll have to delete that "debian" tag.

$ git-tag -l
$ git-tag -d 'debian/<unreleased version>'

Finally, push the repository up to the repository on alioth.

$ git-remote add alioth git+ssh://<username>@git.debian.org/git/pkg-games/<package>.git
$ git-push alioth master
$ git-push alioth upstream
$ git-push alioth pristine-tar
$ git-push alioth --tags

(Again the pristine-tar step is optional.)

Accessing a repository

To get a repository, do the following.

$ git-clone git+ssh://<username>@git.debian.org/git/pkg-games/<package>.git

You can also enjoy read-only access by using the following.

$ git-clone git://git.debian.org/git/pkg-games/<package>.git
$ git-clone http://git.debian.org/git/pkg-games/<package>.git

To view a summary of the repository on your favorite web browser, go to the following address.

http://git.debian.org/?p=pkg-games/<package>.git

Committing changes

To commit a change, first commit into your local repository.

$ git-commit -m "<some comment>"

You could also do a commit of all files that were changed using the '-a' option.

$ git-commit -a -m "<some comment>"

Push your changes.

$ git-push #If you cloned the repository
$ git-push alioth #If you created the repository using the above example

Updating

To keep updated simply do the following

$ git-pull #If you cloned the repository
$ git-pull alioth #If you created the repository using the above exmple

Tagging

To tag a release, you could build it using 'git-buildpackage' with the '--git-tag' option.

$ git-buildpackage --git-tag --pristine-tar

(As usual, the --pristine-tar bit is optional, but it will allow git-buildpackage to extract the pristine .orig.tar.gz.)

You could also manually tag the package. Ensure that you are in the correct branch (should be 'master').

$ git-checkout master
$ git-tag debian/<revision> -m "Debian release <revision>" #Please use this format

To tag an earlier revision, you'll need to find out it's commit object, then tag that object.

$ git-rev-list --pretty --since="1 month" --all #'1 month' is just an example of course
$ git-tag debian/<revision> <commit object> -m "Debian release <revision>"

Finally, push the tags

$ git-push --tags
