Subject: EXDEV when re-init with --separate-git-dir option
Date: Tue, 23 Jul 2024 22:47:19 -0400 [thread overview]
Message-ID: <CAKOkDnMGRfQoNygYLiAxPZB2q=VMYvw8kyu1dM=pM843-FH41Q@mail.gmail.com> (raw)
Dear maintainers,
We discovered that re-init with option --separate-git-dir will throw
an EXDEV when the target directory is not on the same file system as
the original directory.
An example is shown below:
$ mkdir -p fs1/gitdir fs2
$ ls
fs1 fs2
$ sudo mount -t tmpfs tmpfs fs2
$ cd fs1/gitdir
$ git init
Initialized empty Git repository in /home/user/fs1/gitdir/.git/
$ git init --separate-git-dir ../../fs2/surrealgitdir
fatal: unable to move /home/user/fs1/gitdir/.git to
/home/user/fs2/surrealgitdir: Invalid cross-device link
We tested this on version v2.45.2 and after reading the code a bit we
believe the issue still exist in the master branch on github
(https://github.com/git/git/blob/d19b6cd2dd72dc811f19df4b32c7ed223256c3ee/setup.c#L2280).
Best regards,
Di
