git-reflow (2015 Fukuoka Ruby Award Winner)¶ ↑

If your workflow looks like this:

Create a feature branch
Write great code
Create a pull request against master
Get ‘lgtm’ through a code review
Squash merge to master (Why is squash merging our preferred workflow? github.com/reenhanced/gitreflow/issues/52)
Delete the feature branch

Reflow will make your life easier.

Reflow automatically creates pull requests, ensures the code review is approved, and squash merges finished branches to master with a great commit message template.

Quickstart¶ ↑

Create and switch to new branch nh-branchy-branch:

$ git reflow start nh-branchy-branch

Create a pull request for your branch against master or a custom base_branch:

$ git reflow review

If your code is ‘LGTM’d, squash merge to base_branch and delete the feature branch:

$ git reflow deliver

Benefits:¶ ↑

Enforce code reviews across your team.
Know that your entire team delivers code the same way.
Reduce the knowledge needed to deliver great code.
Have a commit history that’s clean and actually usable.
Revert features with ease (if needed).
Work with diverse teams with less worry about different processes.
Stop searching for other git workflows. Reflow covers 90% of your needs without junk you’ll never use.

Features:¶ ↑

Automatically create pull requests to master
Automatically ensure that your code is reviewed before merging
Start with sensible commit messages by default
Squash merge feature branches because results are more important than details
Automatically clean up obsolete feature branches after a successful merge

How to use¶ ↑

Installation¶ ↑

$ gem install reflow

or

$ gem install git_reflow

(‘git_reflow` is the official gem, and `reflow` just declares `git_reflow` as a dependency.)

Setup¶ ↑

On your first install, you’ll need to setup your Github credentials. These are used only to get an oauth token that’s stored in your global git config. We use the Github credentials so we can create pull requests from the command line.

After installation, run:

git reflow setup

It looks like this:

$ git reflow setup
Please enter your GitHub username: nhance
Please enter your GitHub password (we do NOT store this):

Your GitHub account was successfully setup!

This is safe to run multiple times. We don’t care.

Usage with Github Enterprise¶ ↑

To use GitReflow with a GitHub Enterprise account, there are some additional switches available to the GitReflow setup command. You should be able to use GitReflow for both your Enterprise and non-Enterprise repositories. Because of this, there are a few scenarios that may apply to your usage of GitReflow:

You use a GitHub Enterprise account for the majority of your repositories:

git reflow setup --enterprise

After this, anytime you want to use GitReflow with project that uses a regular GitHub account:

cd replace_with_your_non_enterprise_project_path
git reflow setup --local

This will setup your project’s git config with the OAuth token generated from the credentials you provide

If you only use GitHub Enterprise for a select few repositories, you’ll first want to setup GitReflow as normal:

git reflow setup

Then for your Enterprise projects, you have to setup GitReflow for each one:

cd replace_with_your_enterprise_project_path
git reflow setup --enterprise --local

Refreshing your current branch based on your base branch¶ ↑

git reflow refresh

This command updates your feature_branch and base_branch according to the remote_location and then merges your base_branch into your feature_branch. This is just a handy command to keep your branches up to date at any point in time if someone else has committed to the base_branch or the remote.

git reflow refresh -r <remote_location> -b <base_branch_name>

You pass in the name of the remote to fetch from and the name of the base_branch that you would like to merge into your feature_branch. The remote_location defaults to “origin” and the base_branch defaults to “master”. This command also takes in remote and branch name as flag options.

Starting a feature branch¶ ↑

git reflow start

This sets up a feature branch remotely and brings a local copy to your machine. Yeah, you can do this by hand pretty easily, so skip this command if you want. This is just a handy shortcut with no magic.

git reflow start nh-branch-name

“Git Reflow Start” takes in the name of the new branch name that you want to create your feature on. In addition, it takes in an optional flag of a base branch name. If you don’t pass in this parameter, then it defaults to “master”. The base branch name is the base branch that you want to base your feature off of. This ensures that everytime you start a new base branch, it will be based off of your latest remote base.

git reflow start nh-branch-name --base base-branch-name

PROTIP: Use your initials at the beginning of each branch so your team knows who is responsible for each. My initials are ‘NH’, so all of my branches start with nh-

Reviewing your work¶ ↑

git reflow review

All of our work is reviewed by our team. This helps spread knowledge to multiple parties and keeps the quality of our code consistent.

The review step creates a pull request for the currently checked out feature branch against master. That’s all you want to do most of the time. We assume you know what you’re doing, so if you need something different, do it by hand.

After making commits to your branch, run review. Didn’t push it up? We don’t care, we’ll do it for you.

git reflow review -t <title> -m <message>

If you do not pass the title or message options to the review command, you will be given an editor to write your PR request commit message, similar to ‘git commit`. The first line is the title, the rest is the body.

$ git reflow review         

Review your PR:
--------
Title:
rj_209_test

Body:
[lib] updates review command to address issues
--------
Submit pull request? (Y): <enter>
git fetch origin master
From github.com:meesterdude/gitreflow
 * branch            master     -> FETCH_HEAD

git push origin rj_test
Everything up-to-date

Successfully created pull request #6: rj_test
Pull Request URL: https://github.com/meesterdude/gitreflow/pull/6
Would you like to open it in your browser? y

OSX/Ubuntu only: You can automatically open your default web browser to the pull request. This lets you edit the pull request with all of the detailed information you’ll need before submitting it to your team.

We output the pull request URL so you can distribute it to your team without leaving the terminal.

How it works¶ ↑

Behind the scenes, this is how review works:

git fetch origin

Are we up-to-date with changes from master? If not, fail with “master has newer changes”.

Then,

git push origin current-branch # Updates remote branch

Do we have pull request? If not, create it and print “Pull request created at pull-url/”. If so, print the url for the existing request.

Checking your branch status¶ ↑

git reflow status

Sometimes you start working on a branch and can’t get back to it for a while. It happens. Use status to check on the status of your work.

$ git reflow status

Here's the status of your review:
  branches:     reenhanced:nh-readme-update -> reenhanced:master
  number:       35
  reviewed by:
  url:          https://github.com/reenhanced/gitreflow/pull/35

[notice] No one has reviewed your pull request...
Would you like to open it in your browser? n

This gives you details on who’s reviewed your pull request. If someone has participated, but not given you a ‘LGTM’, this will tell you. status prevents you from having to open a browser to find out where your pull request is at. But in case you want to take a look, we give you the option to open it for you.

Delivering approved code¶ ↑

Note: This documentation is for the process for the github “remote” merge process via the github_api. ¶ ↑

For the bitbucket standard or github manual process (used when the user applies -f force flag to the “remote” merge via the github_api), please go to section B.

A:¶ ↑

git reflow deliver

You kick butt. You’ve got your code reviewed and now you’re ready to merge it down to master and deploy. Reflow deliver will take care of all of the steps for you to make this happen.

Reflow’s deliver requires you to have a pull request, so you’ll be protected on those mornings when the coffee isn’t working yet. We built this to get in your way and make you follow the process. If you don’t like it, do it by hand. You already know what you’re doing.

You’ll be presented with a prefilled commit message based on the body of your pull request with references to the pull request and reviewers.

Want to clean up your feature branch afterwards? You’ll be prompted after you edit your commit message if you want to clean up your feature_branch on github. If you answer ‘n’, then your feature_branch will exist for you to clean it up later.

This is what it looks like:

$ git reflow deliver
Here's the status of your review:
    branches:     simonzhu24:test1234 -> simonzhu24:master
    number:       51

Nice job buddy.

How it works¶ ↑

This is what we do behind the scenes when you do deliver

Does a pull request exist?

If not, stop here. You need to run review.
Has the review been completed? Did we get a LGTM from everyone who’s participated?

If not, show a list of authors that need to provide a LGTM.

If the review is done, it’s time to merge. Here’s what happens:

First, we use the github_api gem to merge the pull request.

We call the public API for:

github.pull_requests.merge 'user-name', 'repo-name', 'number', payload

Please take a look at lib/git_reflow/git_server/git_hub/pull_request.rb:102-107 for an example of the call.
This call makes an HTTP request using the Github API to merge the available pull request passing in the user name, repository name, pull request number, and some additional data in the payload.

The payload contains data in the following format:

data = {
  "commit_title",
  "commit_message",
  "sha",
  "squash"
}

Notice: "squash" is set to true, meaning that we will do a squash-merge for each pull request.

For more detailed documentation, please read: https://github.com/piotrmurach/github/blob/master/lib/github_api/client/pull_requests.rb#L197

Next, we prompt you if you want to cleanup Would you like cleanup your feature branch?

If ‘y’, then we’ll update the base_branch and delete the feature branch
```
git pull origin #{base_branch}
git push origin :#{feature_branch}
git branch -D #{feature_branch}
```
If ‘n’, then just stop here. The user can clean up his branch locally.
```
And we're done.
```

This is what the process looks like for bitbucket or if you force deliver:

This is what the default commit message looks like:
Enforces LGTM before deliver, even with no comments.
Removes the need to review the pull request yourself if you make a
comment.

Better error message if setup fails.

Bug fixes.

Closes #36

LGTM given by: @codenamev

Squashed commit of the following:

commit f90e111
Author: Nicholas Hance <[email protected]>
Date:   Thu Jul 11 15:33:29 2013 -0400
...

If the review is done, it's time to merge. Here's what happens:

First, update our local +master+ so we don't get conflicts
  git checkout master
  git pull origin master

Next, squash merge our feature branch
  git merge --squash nh-branch-name

Now, we'll apply a little magic so we have a great commit message by default. Your editor will open and you'll see a nice default for your commit message based on the pull request body.

Once you've saved the commit, prompt the user to see if we should continue
  Merge complete!
  Would you like to push this branch to your remote repo and cleanup your feature branch?

If 'y', then we'll push to +master+ and delete the feature branch
  git pull origin master
  git push origin master
  git push origin :nh-branch-name
  git branch -D nh-branch-name

If 'n', then just stop here. The user can reset his local +master+.
And we're done.

Guiding principles:¶ ↑

Your workflow should resemble the following:

You should already know what you’re doing. We assume you know how to use git.
The master branch is your codebase. You don’t need multiple branches for code actually want to use.
master should remain stable at all times. The entire team depends on it.
No direct commits to master. All work happens in feature branches. From a single commit to hundreds.
All feature branches are reviewed via pull requests.
Looks Good To Me. All feature branches require approval. We look for the string ‘LGTM’ in a comment on the pull request to know it’s ready to merge.
If you make a new commit in your branch, you require another review.
Depending on the minimumApprovals that you specify in your ~/.gitconfig.reflow (created upon reflow setup), you can have the following:

“” : All participants in a pull request must approve the pull request. “0”: 0 approvals required for you to merge PR. “1”: You need a minimum of 1 LGTM and the last comment on your PR must be an LGTM. “2”: You need a minimum of 2 LGTM and the last comment on your PR must be an LGTM. …
Once approved, your feature branch is squash-merged to your base_branch. This makes the history of the base_branch branch extremely clean and easy to follow.
Git blame becomes your friend. You’ll know who to blame and can see the full context of changes. Squash commits to base_branch mean every commit represents the whole feature, not a “typo fix”.

Configuration¶ ↑

In order to streamline delivery you can set the following git config to:

1. always clean up the feature branch after the PR is merged
2. always deliver without further prompt

git config --global --add "reflow.always-cleanup" "true"
git config --global --add "reflow.always-deliver" "true"
