Automate mirroring to GIT

Scripts to keep always up-to-date copies of other repositories via cron.

Status:

The GIT mirroring is proven, the SVN mirroing is a bit experimental. This all here has been rewriten to make it easy to add more VCSses which can act as source for GIT.

Usage:

cd
git clone https://github.com/hilbix/mirror2git
crontab -e

mm hh * * * mirror2git/mirror2git.sh where hh:mm is some time.

GIT:

The GIT mirroring is able to combine several different repositories to one combined repository. If, like HaProxy, the development and stable branches are kept in different repositories, you can join them together again this way.

1a) Prepare the repo:

cd ~/mirror2git/git/
git clone UPSTREAM-GIT-URL somerepo1
cd somerepo1
git remote rename origin upstream

1b) Another way to prepare a repo:

cd ~/mirror2git/git/
mkdir somerepo1
cd somerepo1
git init
git remote add upstream UPSTREAM-GIT-URL

2. Add the GIT server to mirror to. This is your server or, perhaps, GitHub:

cd ~/mirror2git/git/somerepo1
git remote add origin GIT-SERVER-URL-TO-PUSH-TO

3*) Possibly add more repositories to pull information from:

cd ~/mirror2git/git/somerepo1
git remote add upstream2 ANOTHERGITURL
git branch somebranch upstream2/master

SVN:

You need git-svn module. It is part of Debian etc., see apt-get install git-svn

1. Prepare the repo:

cd ~/mirror2git/svn/
git svn clone [--stdlayout] --username=pub SVNURL [somerepo2]

2. Add the GIT server to mirror to. This is your server or, perhaps, GitHub:

cd ~/mirror2git/svn/somerepo2
git remote add origin GIT-SERVER-URL-TO-PUSH-TO

3*) Possibly add more repositories to pull information from:

cd ~/mirror2git/git/somerepo2
git remote add upstream2 ANOTHERGITURL
git branch somebranch upstream2/master

Notes:

• It is unknown if this works in case git-svn clone -s option is used.
• The SVN branch always is on "master"
• Multiple different SVN branches are unsupported. There is no plan to support this.
• If you ever need to change the SVN URL, see https://git.wiki.kernel.org/index.php/GitSvnSwitch

CVS:

CVS IS NOT READY YET!

You need the git-cvs module. It is part of Debian etc., see apt-get install git-cvs

1. Prepare the repo

cd ~/mirror2git/cvs
cvs -d :pserver:anonymous@CVSHOST:/cvsroot/CVSREPO login

git cvsimport -d :pserver:anonymous@CVSHOST:/cvsroot/CVSREPO -A CVSREPO.authors -C CVSREPO -r cvs -k CVSREPO

• Where is CVS? There is a git-cvs module, but it is a bit heuristic. So tracking a CVS repository is not always straight forward. Perhaps when the need arises it will be added.

• Where is hg/Mercurial or bzr/Bazaar? There is a solution for integrating both into git, see http://permalink.de/tino/git-hg This will be added if the need arises at my side or I have the mood to do so.

• Where are other not mentioned VCSses? Not looked into that, yet, sorry.
