How to reopen a pull-request after a force-push?

Precodinitions

• You need the rights to reopen pull requests on the repository.
• The pull request hasn't been merged, just closed.

Instructions

1. Write down the current commit hash of your PR-branch git log --oneline -1 <PR-BRANCH>
2. Write down the latest commit hash on github before the PR has been closed.
3. git push -f origin :

lttlrck

git branch -m old_branch new_branch         # Rename branch locally    
git push origin :old_branch                 # Delete the old branch    
git push --set-upstream origin new_branch   # Push the new branch, set local branch to track the new remote

mobilemind

# delete local tag '12345'
git tag -d 12345
# delete remote tag '12345' (eg, GitHub version too)
git push origin :refs/tags/12345
# alternative approach
git push --delete origin tagName
git tag -d tagName

// Just before switching jobs:
// Add one of these.
// Preferably into the same commit where you do a large merge.
//
// This started as a tweet with a joke of "C++ pro-tip: #define private public",
// and then it quickly escalated into more and more evil suggestions.
// I've tried to capture interesting suggestions here.
