Git madness - Synchronisation from Git to P4

git-to-p4-setup.sh

#
# Suppose that you are happily working with your sources in Git, and manager says 'Thou shalt use the company's Perforce repository'
#
# And you strike a deal: I keep working on Git, but all releases will also be published on Perforce
#
# === Initial setup, run this script once

# My project under Git is located at ~/MyProject

cd MyProject
# Create a published branch
git checkout -b published

mkdir -p ~/toP4 && cd ~/toP4
git-p4 clone //My/Perforce/Repo .

git remote add -t published local file:///home/lclaude/MyProject/
git fetch local published:published
git checkout published
git pull local
git branch --set-upstream published local/published

git checkout master
git checkout -b releases
touch README.txt
git add README.txt
git commit -m "Dummy commit"

git-to-p4-sync.sh

# Run this script once for each release from the ~/MyProject directory

RELEASE=$1

cd ~/MyProject
git checkout published
git merge master
git checkout master

cd ~/toP4
git checkout published@{0}
git reset --soft releases
git commit -m "Release $RELEASE"
git branch temp
git checkout temp
git branch -M releases

git checkout master
git merge releases

git-p4 sync
git-p4 submit
