Gentlemen, I am very thankful for
http://www.mediawiki.org/wiki/Download_from_Git
however it assumes one wants to 'get involved' with MediaWiki, whereas
all I want to do is 'rsync snapshots' of the same files 'that the
tarballs contain'. I.e., I just want to oh, every few days update
(overwrite in place) my running copy of MediaWiki. No need for the
history etc. that a 'clone' pulls in, or further 'pull's refresh.
(The disk size I use should not grow a single bit between updates unless
you upstream added some lines to a file.)
So it would be nice if someone mentioned the commands necessary so I can
add them to that article. Let's pretend we are starting fresh (and not
from SVN like in
http://lists.wikimedia.org/pipermail/wikitech-l/2012-February/058190.html
.)
99M git.git # A --bare clone
167M git-clean # A simple clone of master
215M git-fetch # A clone with a full fetch of the history of all
branches
68M git-linked # A clone linked to git-clean
128M git-shallow # A --depth=5 clone
147M svn # A SVN checkout
Your concerns about space aren't really warranted. For something that
keeps the entire source history it is very efficient at storing that
history.
A basic checkout (git-clean) is only 20MB more than a svn checkout.
To top it off git supports bare repos (repos with only history and no
working copy) and linking a repo to another.
ie: If you `git clone /abs/path/to/other/git/repo newrepo` git will use
some hard links and references to the other repo instead of physically
copying the data.
By the way 99M (git.git) + 68M (git-linked) = 167M (git-clean), a --bare
repo plus a linked repo is the same size as a normal clone.
And it gets even better if you have multiple wikis. If you have a setup
like this:
web/core.git
web/somewiki.com/
web/anotherwiki.com/
Where core.git is a --bare repo and the other two are clones pointing to
core.git, you will actually be SAVING space with git.
In git that's 99M + 68M * 2 = 235M
In svn that's 147M * 2 = 294M
;) Just two wikis and git is already taking less space than svn.
And it goes in git's favor the more wikis you have:
1 = (git: 167M, svn: 147M; diff: -20M | 113.605442177%)
2 = (git: 235M, svn: 294M; diff: 59M | 79.9319727891%)
5 = (git: 439M, svn: 735M; diff: 296M | 59.7278911565%)
10 = (git: 779M, svn: 1470M; diff: 691M | 52.9931972789%)
50 = (git: 3499M, svn: 7350M; diff: 3851M | 47.6054421769%)
100 = (git: 6899M, svn: 14700M; diff: 7801M | 46.9319727891%)
500 = (git: 34099M, svn: 73500M; diff: 39401M | 46.3931972789%)
