Egit/Jgit support for relocated .git directories

Hi,

This is a bit of a secondhand bug report/query so sorry if the details are a bit sketchy.

Since git 1.7.8:

``When populating a new submodule directory with "git submodule init", the $GIT_DIR metainformation directory for submodules is created inside $GIT_DIR/modules/<name>/ directory of the superproject and referenced via the gitfile mechanism. This is to make it possible to switch between commits in the superproject that has and does not have the submodule in the tree without re-cloning.''

I've had several colleagues at work tell me that with the relocated $GIT_DIR the Egit integration with eclipse doesn't work. I can't really qualify "doesn't work" but from what I've been told importing the project works but blaming/annotating doesn't.

I believe the gitfile mechanism isn't new but it possibly hasn't been used by many Egit/Jgit users. Can anyone confirm if it is supported by Egit/Jgit (and I'm barking up the wrong tree).

Thanks,
Chris

I am pretty certain we forgot to support gitfile in JGit. Hence this doesn't work in EGit.

Whoops.

This[1] little snippet makes me think it wasn't entirely forgotten but perhaps not finished or widely tested.

Alternatively as a workaround is there anyway of telling git to use old the behaviour for git submodule init?

It is supported. There is however a commit as late as in May that relates to gitfile, so you may need 2.0.
