git-fpush-refs

#!/usr/bin/env bash

# Sample workflow for dealing with a stack of branches and associated PRs:
#
# 0. Ensure git --update-refs is enabled (only need to do this once):
#    # https://andrewlock.net/working-with-stacked-branches-in-git-is-easier-with-update-refs/
#    git config --global --add --bool rebase.updateRefs true
#
# 1. Make stacked branches, each with commits for logical layers of a feature
#    git checkout -b myfeature-1-api-types master
#    ... && git add . && git commit -m ...
#    git checkout -b myfeature-2-generated-changes
#    ... && git add . && git commit -m ...
#    git checkout -b myfeature-3-validation
#    ... && git add . && git commit -m ...
#    git checkout -b myfeature-4-controller-changes
#    ... && git add . && git commit -m ...
#    git checkout -b myfeature-5-scheduler-changes
#    ... && git add . && git commit -m ...
#    git checkout -b myfeature-6-node-changes
#    ... && git add . && git commit -m ...
#
# 2. git fpush-refs
# 3. Open a PR for each branch
#
# 4. Make updates in response to review comments, absorb into fixup commits for the right branches
#    # https://github.com/tummychow/git-absorb
#    git add ...
#    git absorb --base master
#    git rebase -i --autosquash master
#    git fpush-refs
