Git Logs don't match on setup - work tree with push-to-deploy post-receive hook

I have a push-to-deploy setup with my production server, setting up the directory --bare

to /home/ubuntu/push-to-deploy/test.git

, using this as my remote and adding hooks/post-receive

inside --bare

like below:

#!/bin/bash

while read oldrev newrev ref
do
  branch=`echo $ref | cut -d/ -f3`
  if [ "production" == "$branch" -o "master" == "$branch" ]; then

    git --work-tree=/var/www/test/ checkout -f $branch
    sudo chown -R ubuntu:www-data /var/www/test

    echo 'Changes pushed to Amazon EC2 PROD.'
  fi
done

      

        
        
        
      

    

This works great when clicking on this new remote access from my localhost. post-receive

The script is executed as it should and the content updates are reflected in the directory /var/www/test

as they should. The only thing mine git log

inside /var/www/test

doesn't match my localhost at all. Is this normal behavior --work-tree

? If so, what can I do to keep this functionality push-to-deploy

and still have my git log copied to the production directory as well as the content?

AND

When my content is copied to the production directory ( /var/www/test

), all file owners are overridden ubuntu:ubuntu

, making it www-data

unable to complete my task. I put a string in mine post-receive

to update the ownership after every get, but is there any other way (better way) to do this?

UPDATE

A way to ensure that www-data

persists as the group is to set the guid directory like this:

chmod -R g+s /var/www/test

      

        
        
        
      

    

This will set it to any current directory group, so if you want it to be www-data

, make sure you set the group to www-data

before you run this command.
