Implement a gate between git and mediawiki, allowing git users to push and pull objects from mediawiki just as one would do with a classic git repository thanks to remote-helpers. The following packages need to be installed (available on common repositories): libmediawiki-api-perl libdatetime-format-iso8601-perl Use remote helpers in order to be as transparent as possible to the git user. Download Mediawiki revisions through the Mediawiki API and then fast-import into git. Mediawiki revision number and git commits are linked thanks to notes bound to commits. The import part is done on a refs/mediawiki/<remote> branch before coming to refs/remote/origin/master (Huge thanks to Jonathan Nieder for his help) We use UTF-8 everywhere: use encoding 'utf8'; does most of the job, but we also read the output of Git commands in UTF-8 with the small helper run_git, and write to the console (STDERR) in UTF-8. This allows a seamless use of non-ascii characters in page titles, but hasn't been tested on non-UTF-8 systems. In particular, UTF-8 encoding for filenames could raise problems if different file systems handle UTF-8 filenames differently. A uri_escape of mediawiki filenames could be imaginable, and is still to be discussed further. Partial cloning is supported using one of: git clone -c remote.origin.pages='A_Page Another_Page' mediawiki::http://wikiurl git clone -c remote.origin.categories='Some_Category' mediawiki::http://wikiurl git clone -c remote.origin.shallow='True' mediawiki::http://wikiurl Thanks to notes metadata, it is possible to compare remote and local last mediawiki revision to warn non-fast forward pushes and "everything up-to-date" case. When allowed, push looks for each commit between remotes/origin/master and HEAD, catches every blob related to these commit and push them in chronological order. To do so, it uses git rev-list --children HEAD and travels the tree from remotes/origin/master to HEAD through children. In other words: * Shortest path from remotes/origin/master to HEAD * For each commit encountered, push blobs related to this commit Signed-off-by: Jérémie Nikaes <jeremie.nikaes@ensimag.imag.fr> Signed-off-by: Arnaud Lacurie <arnaud.lacurie@ensimag.imag.fr> Signed-off-by: Claire Fousse <claire.fousse@ensimag.imag.fr> Signed-off-by: David Amouyal <david.amouyal@ensimag.imag.fr> Signed-off-by: Matthieu Moy <matthieu.moy@grenoble-inp.fr> Signed-off-by: Sylvain Boulmé <sylvain.boulme@imag.fr> Signed-off-by: Junio C Hamano <gitster@pobox.com> |

//////////////////////////////////////////////////////////////// GIT - the stupid content tracker //////////////////////////////////////////////////////////////// "git" can mean anything, depending on your mood. - random three-letter combination that is pronounceable, and not actually used by any common UNIX command. The fact that it is a mispronunciation of "get" may or may not be relevant. - stupid. contemptible and despicable. simple. Take your pick from the dictionary of slang. - "global information tracker": you're in a good mood, and it actually works for you. Angels sing, and a light suddenly fills the room. - "goddamn idiotic truckload of sh*t": when it breaks Git is a fast, scalable, distributed revision control system with an unusually rich command set that provides both high-level operations and full access to internals. Git is an Open Source project covered by the GNU General Public License. It was originally written by Linus Torvalds with help of a group of hackers around the net. It is currently maintained by Junio C Hamano. Please read the file INSTALL for installation instructions. See Documentation/gittutorial.txt to get started, then see Documentation/everyday.txt for a useful minimum set of commands, and Documentation/git-commandname.txt for documentation of each command. If git has been correctly installed, then the tutorial can also be read with "man gittutorial" or "git help tutorial", and the documentation of each command with "man git-commandname" or "git help commandname". CVS users may also want to read Documentation/gitcvs-migration.txt ("man gitcvs-migration" or "git help cvs-migration" if git is installed). Many Git online resources are accessible from http://git-scm.com/ including full documentation and Git related tools. The user discussion and development of Git take place on the Git mailing list -- everyone is welcome to post bug reports, feature requests, comments and patches to git@vger.kernel.org. To subscribe to the list, send an email with just "subscribe git" in the body to majordomo@vger.kernel.org. The mailing list archives are available at http://marc.theaimsgroup.com/?l=git and other archival sites. The messages titled "A note from the maintainer", "What's in git.git (stable)" and "What's cooking in git.git (topics)" and the discussion following them on the mailing list give a good reference for project status, development direction and remaining tasks.
