Package: pristine-tar
Version: 1.25
In the current version of git, the "git submodule" commands create
submodule repos which do not have .git subdirectories, but instead
have .git files which contain text with a redirection pointer.
This causes "pristine-tar commit" to fail rather mysteriously when it
tries to access files in .git/* directly. The pristine-tar program
really should be using the appropriate git commands instead.
The "right" way to find the true git subdirectory, following textual
redirects etc, is:
git rev-parse --git-dir
If not inside a git repo this will give an error status, so it is also
a good way to check if you're inside a git repo.
I should say that "pristine-tar checkout" works even when
"pristine-tar commit" does not, so this is a pretty easy problem to
work around: just make a non-submodule clone of the repo in question,
"pristine-tar commit" there, and push the pristine-tar branch back
into the submodule.
Below:
- example of non-directory .git in submodule
- example pristine-tar commit failure in said repo
- example of how a user can work around problem
(The last of these three is provided for other users who come across
this problem and find this bug report.)
Cheers,
--Barak.
