deploy.sh

#!/bin/bash
echo "fetching changes from the remote repository ..."
cd /home/www/devnavigator.co.za/laravel
hg revert --all --no-backup

## the following command fails, because mercurial doesn't know 
## the user credentials to connect to the remote repo

hg pull
hg update master
echo "done"

## I can tell Mercurial which user to use by putting a ~/.hgrc config file in the user's home folder
## Problem is, apache currently doesn't run as a user with a home folder

Here's a log dump from /home/www/[redacted]/deployments.log
It can be viewed at 

2014-11-28 10:00:55+02:00 --- INFO: Attempting deployment...

Which shows the script didn't pull in any changes. If I ssh in and run the deploy as a user, the changes are pulled:

jannie@devserver:~$ deploy
