Git

Git est un gestionnaire de versions (comme svn, cvs ou d'autres) décentralisé.

Bonne doc en français sur http://alexgirard.com/git-book/index.html

Mais, parfois, la centralisation s'avère pratique, et c'est aussi possible.

Cf http://scie.nti.st/2007/11/14/hosting-git-repositories-the-easy-and-secure-way, http://www.nikrou.net/post/2009/02/20/Mettre-en-place-un-d%C3%A9p%C3%B4t-central-git ou http://blog.touv.fr/2009/06/depot-git-prive-et-personnel-sur.html pour l'install du dépot central.

Opérations courantes

http://www.kernel.org/pub/software/scm/git/docs/user-manual.html#git-quick-start

# transformer le dossier courant en projet git
git init
# ajouter tous ses fichiers au projet (ou bien préciser les fichiers à ajouter)
git add .
# ajouter un alias pour un projet sur un serveur distant
git remote add alias_de_ce_projet_sur_ce_serveur user@server:path/2/le_projet.git
# y envoyer les fichiers
git push alias_de_ce_projet_sur_ce_serveur la_branche # "master" pour la branche principale
 
# commit d`un fichier (localement)
git commit -m 'message de commit' le_fichier
# commit de tous les fichiers (localement)
git commit -m 'message de commit' -a
# envoi de tous les derniers commit (depuis le dernier push) sur le serveur
git push

Avec les prefs

echo 'GIT_REPOSITORIES=/home/git/repositories/' > /etc/default/git-daemon

Mais tout ça sert pas à grand chose car il y a un paquet git-daemon-run, qui, comme son nom l'indique…

Bref, ce qui suit va quand même plus vite

aptitude install git-daemon-run
ln -s /usr/bin/sv /etc/init.d/git-daemon
# et on va modifier /etc/sv/git-daemon/run pour préciser le --base-path
