For reasons which would take a while to explain, I'm building a repository in a directory using "--git-dir=xxxx/.git --work-tree=." and then doing an "mv xxxx/.git ./.git" and then trying to work with that repository --- but can't

Below is a sample script. The last line (git add) fails with

fatal: unable to create '/usr/local/AusTop/AuPrograms/AuServer/testgit/aaa/bbb/.git/index.lock': No such file or directory

git doesn't seem to realise that there is a .git back up the tree.

I'm using 1.5.5.1

Cheers, Geoff Russell

It's because when you did git --work-tree=. init, worktree is stored in .git/config. The code that chdir() in setup_git_directory() probably forgot to chdir() back to toplevel worktree. Workaround could be just remove core.worktree in .git/config.

Many thanks, the work-around works. I'm not sure if this is a bug or a feature, but I'm happy either way.

That depends on what the value of core.worktree is:
 - If it is '.', than I think it should be considered a bug in git init,
   because that value is just plain nonsense.
 - If it is '..', than it's a user error and the right thing is to just
   remove it when you relocate the .git directory.
 - If it was '/usr/local/AusTop/AuPrograms/AuServer/testgit/' than it would
   have worked, so it's not that.

Best regards, Jan
