# Script for generating a list of candidates for cherry-picking to a stable branch
#
# Usage examples:
#
# $ bin/get-pick-list.sh
# $ bin/get-pick-list.sh > picklist
# $ bin/get-pick-list.sh | tee picklist

# Use the last branchpoint as our limit for the search
latest_branchpoint=`git merge-base origin/master HEAD`

# Grep for commits with "cherry picked from commit" in the commit message.
git log --reverse --pretty=medium --grep="cherry picked from commit" $latest_branchpoint..HEAD |\
	grep "cherry picked from commit" |\
	sed -e 's/^[[:space:]]*(cherry picked from commit[[:space:]]*//' -e 's/)//' > already_picked

# Grep for commits that were marked as a candidate for the stable tree.
git log --reverse --pretty=%H -i --grep='^CC:.*mesa-stable' $latest_branchpoint..origin/master |\
