@khalsah I'm digging it so far. I think that the merging of the branch to master for deployment is great and the usage rev-parse is great and I have rarely seen --porcelain used but all in good practice.

Interesting error message. (Obvious locations left out-- but you get the gist of it. Heh-- stupid puns).

I just did the git commit -m and ./deploy.sh again and all was well.

Sounds like the file somehow diverged between your local copy and what was on the server. When you ran deploy it tried to pull in the sync from the server which failed with a conflict. When you did a commit you created a merge that picked which version to use allowing the commit to be deployed. Can't tell you why the files diverged though.

I encountered that issue again this morning. I think it had something to do with the CRONJOB running /hooks/sync at midnight and when I went to deploy I got the same message spit at me. Odd. This is still more effecient than my previous deployment methods for WP sites.

Forgot to ask you today. When I am setting up these 'web' or 'deploy' repositories on the client's server (to deploy too), I do a basic git init since we discussed not using git --bare init on these repositories. I've had to add git config receive.denycurrentbranch=ignore to each repository. That makes sense, right? If I don't add that, the push does not work at all because of the fast-forward. (Correct, or am I thinking about that the wrong way?). Only reason I ask, is because that's how I am setting up a new repo right now.

# From Remote machine
git init
git config receive.denycurrentbranch=ignore
git add --all
git commit -m "Initial Commit"
git remote add origin git@bitbucket.org:username/websitename.git
git push origin master
git branch -l deploy
touch .git/hooks/post-receive && chmod +x .git/hooks/post-receive #Add post-receive content
touch .git/hooks/sync && chmod +x .git/hooks/sync #Add sync content

# From Local Machine
git init
git remote add origin git@bitbucket.org:username/websitename.git
git remote add deploy ssh://user@server.com/home/user/websitename.com/.git/
git add --all
git commit -m "Initial Commit."
touch ./deploy.sh && chmod +x ./deploy.sh # Add Deploy content
./deploy.sh

That all makes sense, right?

Added [ -f /usr/local/bin/growlnotify ] && growlnotify -s -m "Project has been Deployed" || echo "Project has been deployed" for Mac OSX Growl Notification. Quick check to see if Growl is Installed (in the proper place) then notifies that the project has been synchronized with a fall-back using echo. Nice for those large commits that take a little while. I'll jump over to another window or screen and work on something-- then am notified that the Sync was complete.

It's all about the simple things in life.
