Hi, I created a repository, and I don't want somebody to pull some branch or tag from my repository with git protocol. How can I do ?
Thanks, Emily

By not putting that tag or branch in that repository (note that you can have a repository only to publish which is different from your main working repository). .

I want some group can pull these branches or tags from my repo, while other's can't, Need I maintain two repositories ?

I think gitosis should be able to do that? Otherwise you could look into hosting sites like github or gitorious, I think they have at least some form of access control, yes?

Sverre, Thank you for your information ! As far as I know, gitosis can control someone readonly/writable to some repo, it has no access control on branch/tag level. Am I right ?
I'll look at github and gitorious, are they free software ?
Thanks, Emily

Ah, sorry, I meant to control access to different repo's for different groups.

IIRC gitorious is open source, but I just checked and I don't see any access control there; which leaves github, which is not free software I'm afraid.
I think, as Johannes said, keeping two seperate repo's and using some form of access control on those would be best.

Sverre, Johannes,
Thank you very much for sharing your good idea ! Yes, maintaining two separate rep maybe best.
Johannes, Does your second suggestion mean that I need to write a script and use git hook to enable it ?
Thanks, Emily

Either that (that would be the easy method, and also the proper one, since people would not even know what you hide), but you could patch upload-pack so that it runs a hook with the rev-list arguments in do_rev_list() in upload-pack.c, and die() if the hook returns non-zero.

I do not think that would work very well as you expect. Two branches can be pointing at the same commit, and Emily may want to hide one but not the other. The time you obtain from "want" is too late.
If you were to extend upload-pack, the place to narrow would be the initial "here are the refs and the objects they point at" announcement that is done at the very beginning. You would do something like the pseudo patch attached at the end.
read_set_of_exposed_refs_from_hook() should return, depending on who the user is (which is obviously not available if this connection is over the anonymous git-daemon service, but local and usual ssh connection you could do whoami, and on gitosis there would be some environment variable to distinguish who you are that you can use), the set of refs that the user is allowed to see.

Yes, it is easy: do not push it into that repository.
If you already did, delete it in that repository.
