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> |

Contributed Software Although these pieces are available as part of the official git source tree, they are in somewhat different status. The intention is to keep interesting tools around git here, maybe even experimental ones, to give users an easier access to them, and to give tools wider exposure, so that they can be improved faster. I am not expecting to touch these myself that much. As far as my day-to-day operation is concerned, these subdirectories are owned by their respective primary authors. I am willing to help if users of these components and the contrib/ subtree "owners" have technical/design issues to resolve, but the initiative to fix and/or enhance things _must_ be on the side of the subtree owners. IOW, I won't be actively looking for bugs and rooms for enhancements in them as the git maintainer -- I may only do so just as one of the users when I want to scratch my own itch. If you have patches to things in contrib/ area, the patch should be first sent to the primary author, and then the primary author should ack and forward it to me (git pull request is nicer). This is the same way as how I have been treating gitk, and to a lesser degree various foreign SCM interfaces, so you know the drill. I expect that things that start their life in the contrib/ area to graduate out of contrib/ once they mature, either by becoming projects on their own, or moving to the toplevel directory. On the other hand, I expect I'll be proposing removal of disused and inactive ones from time to time. If you have new things to add to this area, please first propose it on the git mailing list, and after a list discussion proves there are some general interests (it does not have to be a list-wide consensus for a tool targeted to a relatively narrow audience -- for example I do not work with projects whose upstream is svn, so I have no use for git-svn myself, but it is of general interest for people who need to interoperate with SVN repositories in a way git-svn works better than git-svnimport), submit a patch to create a subdirectory of contrib/ and put your stuff there. -jc
