I'm new to git so I apologize开发者_运维百科 (and please correct me) if I misuse terminology here, but I'll do my best.

I'm trying to set up a bare git repo (hub) and a development site working copy (prime) on a web server. I've tried to pattern it after this article. I want the development working copy to be updated whenever the hub repo is pushed to. I'm under the impression that the proper hook for this is post-update, which I have created like so:

#!/bin/sh
whoami
cd /path/to/working-copy/
RET=`git pull`
echo $RET

Update

When I push changes from my local repo to the bare hub I get the following output from the post-update script:

remote: sites
remote: fatal: Not a git repository: '.'

However if I SSH into the server as user 'sites' and execute this script manually it works great Any ideas as to what might be going wrong with this hook or script?

Here is the script that ultimately worked. I think the bit I was originally missing that prevented it from working remotely was the unset GIT_DIR

#!/bin/sh
cd /path/to/working-copy/ || exit
unset GIT_DIR
git pull repo branch

exec git-update-server-info

Try instead:

#!/bin/sh
cd /path/to/working-copy/
env -i git pull

Despite that unset GIT_DIR just works.

the problem occurs when you set GIT_DIR wrongly somewhere else.

you can just add that instead: GIT_DIR=.git/ It will work

In my case I had specified a working tree, and this breaks on some commands, like pull (or more precisely fetch).

To unset the working tree if it is in your git config is via:

git config --unset core.worktree

(There are other ways to set a work tree)

Important to note,

There is next to no change of this being your problem unless you yourself dug this hole around you by using a custom worktree in the first place.

Banter:

This implies to me that git internals use paths relative to the worktree + .git/ in some cases. In my experience worktrees are not well supported whatsoever, except by the most fundamental parts of git. I have not experimented thoroughly, Git would probably behave if I set whatever the git directory config variable is properly, which I have not played with.

You probably have a permissions issue. I'm not sure how you have setup your bare git repo, but if it's running under the git user, make sure that git user is allowed to perform the git pull in your project directory.

Optionally try this to find out what user you are when the hook is run:

echo `whoami`
