Question

I have this simple hook on /hooks/post-update inside a bare repository:

#!/bin/sh
git-update-server-info

GIT_WORK_TREE=/home/user/apps/application-site/dev git checkout -f develop
GIT_WORK_TREE=/home/user/apps/application-site/dev git submodule update --init

GIT_WORK_TREE=/home/user/apps/application-site/master git checkout -f master
GIT_WORK_TREE=/home/user/apps/application-site/master git submodule update --init

The repository has some submodules, that I am expecting is pushing to production server, and checkout the two branches on two directories, so can I have later a dev.myapp.com for the development branch and http://www.myapp.com for the master branch, and all this updating also the submodules on the branches.

Checkout is working as expected, but not the submodule update –init, :'(

The remote output raises this errors.

remote: Switched to branch 'develop'
remote: You need to run this command from the toplevel of the working tree.
remote: Switched to branch 'master'
remote: You need to run this command from the toplevel of the working tree.

I am not quite sure what to do.

The answer is to do exactly what git is telling you, which is:

remote: You need to run this command from the toplevel of the working tree.

So do that. Here’s a sample post-update hook:

#!/bin/sh

export GIT_DIR=$(pwd)

cd /home/lars/projects/stackoverflow/gitstuff/worktree

git checkout -f master
git submodule init
git submodule update

This assumes that:

• core.bare is false
• receive.denyCurrentBranch is ignore. You need this because otherwise you’ll get an error pushing into a repository with core.bare set to false.

…and seems to work in my limited testing.
