Required packages:

• git-core
• git-core-slug (suggested, >= 0.12)
• rpm-build-tools >= 4.5-3

Move existing ~/rpm directory:

mv ~/rpm ~/rpm.cvs

Prepare new directory:

builder --init-rpm-dir

For now one needs to use local ~/rpm/packages/builder:

cd ~/rpm/packages/
./builder -v -bp python-msgpack

Your identity (NOTE: This sets globally):

git config --global user.name "Your Name"
git config --global user.email <email>

One can do it per package too in each ./.git/config file:

[user]
      email =<your_login>@pld-linux.org
      name = Your Name

but as for now one needs to set it in each package fetched.

If you have an RW access to PLD Linux repositories please use your PLD Linux alias <your_login>@pld-linux.org> as email.

Additionally some useful git config:

Enable colored difs (reference)

git config --global color.ui auto

Add git st alias (reference)

git config --global alias.st status
git config --global alias.ci commit
git config --global alias.up pull --rebase

 git clone git://git.pld-linux.org/packages/<package>
 cd <package>

or

 slug.py clone <package>
 cd ~/PLD_clone/packages/<package>  # FIXME: Is it ~/rpm/packages/<package> in newer vesions ?

If you have RW access you can also use ssh access:

 git clone git@git.pld-linux.org:packages/<package>
 cd <package>

In directory you will find local copy of main branch in the upstream repository. It is usually called master.

In git repositories there are two kind of branches: local ones on which you work, and remote ones, which tracks changes in upstream repository. The remote branches live in a different namespaces: remotes. The default remote is called origin, so the main remote branch is usually called origin/master. Clone, besides other things, creates a local master branch that tracks remote origin/master branch.

First you put your changes in a staging area - the index:

  git add file

Then you can produce a commit from contents of index:

  git commit

You can also skip the staging area by:

  git commit -a

It will commit the changes in every tracked file. If you want to add new file to the repository you still need to add it explicitly with git add

Remarks:

• Commit in git are atomic so put related changes to multiple files into one commit.
• Write nice commit logs.

Most git operations change only your local repository. If you want to update upstream repository you need to push your changes. However if you have cloned the packages using git directly from git daemon, you need first to set URL for pushing (for obvious reason anonymous pushes using git daemon are not supported):

  git remote set-url --add --push origin git@git.pld-linux.org:packages/<package>

If you have cloned the repository using slug.py too, the URL for pushing has been already set by slug.py.

Then you can push your changes:

  git push origin master

where master is a name of branch you want to push. If you are not certain whether you will push to the right branch you can first try:

 git push --dry-run origin master

 git fetch origin

It will update all your remote-tracking branches. It will not change your local branches or working directory. For this you need to commit your changes to your local branch and then explicitly merge changes from remote branch to it. For example:

 git merge origin/master

Alternatively to get a more clean history you can rebase your changes on top of remote branch:

 git rebase origin/master

First you need to create your local branch. If you want to follow the remote branch foo, the simplest way is to:

git checkout <branch>

It will create local branch <branch> which tracks remote branch origin/<branch>.

List all your local branches:

 git branch

All remote branches:

 git branch -r

All branches (local and remote)

 git branch -a

Sometimes it is useful to see a graphical representation of all branches. It can obtained with:

 gitk  --all

You can limit the set of commits shown by by gitk. For example to present only two branches:

 gitk branch1 branch2

slug.py init <package>

To be able to use builder script or push your changes upstream you have to create local branch in newly created repository:

cd <package-repo>
touch <specfile>
git add <specfile>
git commit -m 'Init commit'

and then:

git push -u origin master

After pushing for the first time you may also need to set local master branch to track remote master:

git branch --set-upstream master origin/master

Often it is good idea to start working over new spec starting from spec templates available:

git clone git://git.pld-linux.org/projects/template-specs.git

"Pro git" book

To list currently available keys:

ssh  git@git.pld-linux.org sskm list

If you use different keypair (.ssh/id_rsa_pld_linux in my case) to connect specify it:

ssh -i ~/.ssh/id_rsa_pld_linux git@git.pld-linux.org sskm list

One can even make keypair change transperent by adding ~/.ssh/config:

Host git.pld-linux.org
   IdentityFile ~/.ssh/id_rsa_pld_linux
   

Generate pair ( id_rsa_matkor_pld_linux_app4 and id_rsa_matkor_pld_linux_app4.pub in ma case)

 ssh-keygen -f ~/.ssh/id_rsa_matkor_pld_linux_app4
 

Add it (as key app4 in my case):

cat ~/.ssh/id_rsa_matkor_pld_linux_app4.pub  | ssh git@git.pld-linux.org sskm add @app4

Confirm (using -i of new key ):

ssh -i ~/.ssh/id_rsa_matkor_pld_linux_app4   git@git.pld-linux.org sskm confirm-add @app4
