Subject: [PATCH] submodules: ensure clean environment when operating in a submodule
Date: Mon, 22 Feb 2010 23:16:55 +0100 [thread overview]
Message-ID: <1266877015-7943-1-git-send-email-giuseppe.bilotta@gmail.com> (raw)
In-Reply-To: <20100218203726.GD12660@book.hvoigt.net>
git-submodule takes care of clearing GIT_DIR whenever it operates
on a submodule index or configuration, but forgot to unset GIT_WORK_TREE
before operating on the submodule worktree, which would lead to failures
when GIT_WORK_TREE was set.
This only happened in very unusual contexts such as operating on the
main worktree from outside of it, but since "git-gui: set GIT_DIR and
GIT_WORK_TREE after setup" (a9fa11fe5bd5978bb) such failures could also
be provoked by invoking an external tool such as "git submodule update"
from the Git GUI in a standard setup.

The bug (git submodules not working in Git GUI since my patch) was spotted by
Heiko Voigt working on/with msysgit, and he kindly provided a recipe to
replicate it:
http://article.gmane.org/gmane.comp.version-control.msysgit/8755
I'm pretty confident fixing this on the submodules side is the more correct
approach, since otherwise even a simple
$ GIT_WORK_TREE=. git submodule update
on the command-line can fail.
I also believe this is material for git maint.
