Sparse checkout example in git 1.7.0

Sparse checkout example in git 1.7.0
Sparse checkout is now part of git-1.7.0. See here on what it is in general. Basically something what svn already knew for years and git did not. And of course git now does it better, since this way it’s possible to checkout multiple sub-directories, not just a single one, what svn allows.
Here is a short example:
$ git clone ~/git/git $ cd git $ ls|wc -l 361 $ git config core.sparsecheckout true $ echo ppc/ > .git/info/sparse-checkout $ echo perl/ >> .git/info/sparse-checkout $ git read-tree -m -u HEAD $ ls perl/ ppc/
Enjoy! :)
Update: see the comments, as it has been pointed out the “And of course git now does it better, since this way it’s possible to checkout multiple sub-directories, not just a single one, what svn allows.” sentence is incorrect; but of course having a similar feature in a distributed VCS is still an improvement. ;)

Is it possible to just get the contents of a subdirectory, like how you can in SVN? Say I just wanted the contents of the 'perl/' dir, without an actual dir named 'perl' ?

I think that's only possible when you use submodules, see man git-submodule. But if you want to be sure, ask on the git list. :)

FWIW, svn had sparse checkouts for *ages*.
With multiple directories.

Care to link some documentation how it is possible to do so?
I mean in case I have 3 subdirs in a repo and I want to check out only 2 of them. Manually checking out 2 of them is a no-go because then svn up won't update both.
Thanks.

vmiklos: something like the following would get you two directories. (Note that I'm not saying whether one is better than the other, but saying that svn doesn't support that is just wrong.)
svn checkout $url --depth empty
svn update --set-depth infinity dir1
svn update --set-depth infinity dir2
svn checkout $url --depth empty
svn update --set-depth infinity dir1
svn update --set-depth infinity dir2

(Ugh, the last two updates should be done in the checkout empty directory, of course.)

Eli,
Thanks for the correction, I corrected the post. (See the update at the end of the post.)

vmiklos: Thanks :)

Sweet, but how do you turn it off once you've applied it.
Doing
$ echo "" > .git/info/sparse-checkout
as well as
$ git config core.sparsecheckout false
followed by
$ git read-tree -m -u HEAD
$ git pull
does not work... as I would have expected?

In your example i must first clone and then use "sparse checkout". Facing a large repository and read-only mode, i want "only" part of the repository, never all.

@Benjamin The best is to ask on the mailing list, right now I don't have time to dig the answer up for you, sorry.
@neokrates: You have various options, probably you just want git clone -n, that won't do a checkout, and then once you set up sparse checkout, you can do one.

@Benjamin I changed my mind, here is what you need:
echo '*' > .git/info/sparse-checkout
git read-tree -m -u HEAD
Then you can do:
rm .git/info/sparse-checkout
git config core.sparsecheckout false
(See man git-read-tree.)
echo '*' > .git/info/sparse-checkout
git read-tree -m -u HEAD
Then you can do:
rm .git/info/sparse-checkout
git config core.sparsecheckout false
(See man git-read-tree.)

@vmiklos Thank you for that great idea. Will try it on our build chain.
