Hi,
I was just setting up a new project using submodules and have run into
what appears to be a hang when git status is invoked. I haven't tried
to reproduce this but this is basically what I did (edited highlights
from my bash_history).
$ git --version
git version 2.0.3
$ mkdir proj
$ cd proj
$ git init
$ git submodule add <internal-repo-with-build-scripts> build
$ git submodule add --reference ~/src/linux/.git
git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git linux
# I'm not sure if the --reference is relevant but I was just wanting
to cut down on my network transfer
$ git submodule add <internal-repo-with-skeleton-fs> rootfs
Oops I really wanted linux-stable to get the same version my board
vendor is using
$ vim .gitmodules
# change to linux-stable
$ git submodule sync
I'm not sure if this is a valid use-case but nothing complained that I
was changing the URL. In theory linux-stable should be a super-set of
linus' tree so the repositories are basically equivalent.
$ cd linux/
$ git remote show origin
* remote origin
Fetch URL: git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git
# Seems to have done the trick
$ git reset --hard v3.4.69
I suspect this is where the problem starts. When I did the git
submodule add it was pointing at the tip of linus' tree. Now I have
rewound considerably.
$ git status
[hang]
For what it's worth here's the output when I run with GIT_TRACE=1 git status
