# Called by "git push" after it has checked the remote status, | |
# but before anything has been pushed. | |
# | |
# If this script exits with a non-zero status nothing will be pushed. | |
# | |
# Steps to install, from the root directory of your repo... | |
# 1. Copy the file into your repo at `.git/hooks/pre-push` | |
# 2. Set executable permissions, run `chmod +x .git/hooks/pre-push` | |
# 3. Or, use `rake hooks:pre_push` to install | |
# | |
# Try a force push to master, you should get a message `*** [Policy] never force push...` | |
# | |
# The commands below will not be allowed... | |
# `git push --force origin master` | |
# `git push --delete origin master` | |
# `git push origin :master` | |
# | |
# Nor will a force push while on the master branch be allowed... | |
# `git co master` | |
# `git push --force origin` | |
# | |
# Requires git 1.8.2 or newer | |
# | |
# Git 1.8.2 release notes cover the new pre-push hook: | |
# <https://github.com/git/git/blob/master/Documentation/RelNotes/1.8.2.txt> | |
# | |
# See Sample pre-push script: | |
# <https://github.com/git/git/blob/87c86dd14abe8db7d00b0df5661ef8cf147a72a3/templates/hooks--pre-push.sample> | |
