The document root of my website has a git repository under it (in the standard .git subdirectory) and want a post update hook to checkout the contents (so the web server sees it!)

I will be pushing to it via ssh.

Does this mean that the post-update hook with be run with a working directory of the web site's document root? or something relative (such as GIT_DIR) so that I don't have to do a specific cd to an absolute path.

I found it out, by getting the post update hook to e-mail me the value:-)

its in the repository (ie document_root/.git)

The current implementation happens to chdir to GIT_DIR and sets GIT_DIR=. in the environment, so if you have something like this:

	/var/www/myproject/
	/var/www/myproject/.git/
	/var/www/myproject/.git/HEAD
	/var/www/myproject/.git/...
        /var/www/myproject/README

Then $(pwd) would be /var/www/myproject/.git/. Your hook would probably be able to do "cd .." to get to the project top.

However, there is no guarantee for future implementations.

I did get it to work doing a cd .. - although you also have to unset GIT_DIR, because its is literally "." and not the directory that was "." at the time of setting, so a cd .. ; checkout -f then fails with an invalid repository.
