Annoying absolute path for "core.worktree" to submodule

Annoying absolute path for "core.worktree" to submodule

[Christian Hammerl]

Hey folks,

I really love the work you are doing on GIT but the last update
regarding submodules is a bit annoying. Although the path inside the
".git" file is stored relative to the submodule's path, the path in
".git/modules/path-to-submodule/config" is stored as an absolute path
for "core.worktree".

I develop (for some projects) within a chroot where I have a different
username and therefore the path differs if I am currently inside the
chroot or not. If the submodule is initialized inside the chroot, I
always get this message when I cd into the project's directory outside
of the chroot:

fatal: Could not switch to
'/home/chroot-username/parent-path-of-submodule': File or directory not
found
fatal: 'git status --porcelain' failed in submodule
relative-path-to-submodule

This is caused by using `__git_ps1` for my bash-prompt. I don't know
exactly where the problem is and what actions (called by __git_ps1) are
responsible for this.

Any suggestions how to deal with this?

And no, removing __git_ps1 from my bash-prompt is not the answer, I
like this feature very much. ;-)

Thanks in advance
Christian

What are you referring to as the "last update"? v1.7.8 introduced the 
separate git dir for submodules, and used an absolute path.

This absolute path was changed to a relative path in the patchset at 
[1], which is present in v1.7.10-rc1.

Slightly off topic, but related, what is the recommended way for finding
the git folder from the top level project or any of the submodules? And
of finding the working tree from inside a hook script?

Context: One of the (optional) steps in our build process installs
pre-commit hooks into the git/hooks folder of the tools submodule and
into the git/hooks folder of the next level up project. Then on commit
the hook reads the config file from inside the tools submodule and
checks file formats and naming standards before permitting the commit.
The current implementation has the paths hard coded between the two
location, now with some having the old layout and some the new, we are
looking for a consistent solution without duplicating the logic in the
git executables.

Run "git rev-parse --git-dir" inside the repo whose git folder you want to
know.

I would expect hooks to be run in the work tree's top level directory,
but I haven't checked that.

Ah ok, my current Version is 1.7.9.4. I did not recognize this
behaviour before, so I assumed it came with the last update. Sorry for
that.

I see, thanks for the information.
I think I will wait until my linux distribution will update the
package to 1.7.10. For now it works for me to replace the .git file
with the corresponding repository which is located at ".git/modules/*"
within the superproject.
