Introduction

Welcome back, fellow developer! So far, we’ve explored the magic of GitButler locally, creating virtual branches, stacking changes, and managing our work with unparalleled flexibility. But what good is amazing local productivity if you can’t share it with your team? This chapter is all about bridging that gap.

We’ll dive into how GitButler seamlessly integrates with your remote repositories. You’ll learn the crucial “Publish” action, which transforms your local virtual branch stacks into conventional Git branches on your remote. More importantly, we’ll guide you through the process of preparing these published branches for pull requests, embracing the powerful concept of stacked pull requests that streamlines code review and collaboration.

By the end of this chapter, you’ll be able to push your carefully crafted GitButler stacks to GitHub, GitLab, or any other Git host, and set up your pull requests for a smooth, efficient review cycle. Let’s get your brilliant work out into the world!

Core Concepts: From Local Stacks to Remote Collaboration

Integrating your local GitButler workflow with a remote repository is where the real collaborative power shines. GitButler’s approach simplifies what can often be a complex and error-prone process in traditional Git, especially when dealing with dependent changes.

GitButler’s Remote Integration Philosophy

Unlike traditional Git where you manually manage which local branch tracks which remote branch, GitButler takes a more holistic view. When you “publish” a stack of virtual branches, GitButler intelligently creates corresponding conventional Git branches on your remote repository. This means your team can interact with your work using familiar Git commands and platforms, while you continue to enjoy GitButler’s local superpowers.

The core idea is to let GitButler handle the underlying Git mechanics, allowing you to focus on your changes and their logical progression.

Publishing a Virtual Branch Stack

Imagine you’ve built a feature that required several small, dependent changes. In GitButler, these are individual virtual branches stacked on top of each other. When you’re ready to share, you “publish” this entire stack.

What does “publish” mean? GitButler performs a series of Git operations behind the scenes:

  1. Creates Remote Branches: For each virtual branch in your stack, GitButler creates a new, independent branch on your remote repository. These remote branches are named based on your virtual branch names (e.g., feature/login-ui, feature/login-api).
  2. Pushes Commits: It pushes the commits from each virtual branch to its corresponding remote branch.
  3. Maintains Dependencies: Crucially, it ensures that the commits reflecting the dependencies between your virtual branches are correctly represented in the remote branches.

This process is designed to be idempotent: you can publish multiple times, and GitButler will update the remote branches as needed, even handling cases where you’ve reordered or rebased your local stack.

Preparing for Stacked Pull Requests (PRs)

The true elegance of publishing stacks lies in how it facilitates stacked pull requests. Instead of one monolithic PR for a large feature, you create smaller, more digestible PRs, where each PR builds on the previous one.

Consider our example stack:

  • refactor/auth-middleware (base)
  • feature/login-api (depends on refactor/auth-middleware)
  • feature/login-ui (depends on feature/login-api)

When published, these become three distinct remote branches. You would then create PRs like this:

  1. PR 1: refactor/auth-middleware into main (or your target integration branch).
  2. PR 2: feature/login-api into refactor/auth-middleware.
  3. PR 3: feature/login-ui into feature/login-api.

This approach offers significant benefits:

  • Easier Review: Each PR is smaller, focused on a single logical change, making it quicker and easier for reviewers to understand and approve.
  • Faster Feedback: Reviewers can provide feedback on the base changes without waiting for the entire feature to be complete.
  • Improved Agility: If a lower-level PR needs changes, you can address them, update the PR, and the subsequent PRs will automatically update (or require a simple rebase within GitButler) to reflect the changes.

Here’s a visual representation of how a local GitButler stack translates to remote branches and stacked PRs:

Keeping Remote in Sync

Once published, your virtual branches are linked to their remote counterparts. Any further changes you make locally to a virtual branch that has been published will be reflected on the remote branch the next time you publish. GitButler is smart enough to handle the updates, including any necessary rebases or force pushes (which it manages safely for you).

Step-by-Step Implementation: Publishing and PR Prep

Let’s put these concepts into practice. We’ll assume you have an existing GitButler repository with a few stacked virtual branches. If not, quickly create a new repo, commit to main, then create feature/first-step, add a commit, and then feature/second-step on top, adding another commit.

Step 1: Reviewing Your Local Stack

Before publishing, it’s always a good practice to review your current work.

  1. Open GitButler: Ensure you have your repository open in the GitButler desktop application.

  2. Inspect the “Active Branches” View: Look at the left-hand panel where your virtual branches are listed. Verify that the order and content of your branches are as you intend. You can click on each branch to see its commits.

    Self-reflection: Are the commit messages clear? Is each branch focused on a single logical change? This is your last chance to easily tweak things locally before pushing to remote!

Step 2: Publishing Your Stack to Remote

Now, let’s send your work to the remote.

  1. Locate the “Publish” Button: In the GitButler UI, usually at the top right of the “Active Branches” panel, you’ll find a “Publish” button. It might also indicate how many branches are “ready to publish.”

  2. Click “Publish”:

    • GitButler will analyze your local virtual branches and compare them with the remote.
    • It will then perform the necessary Git operations (creating remote branches, pushing commits) to synchronize your stack.
    • You’ll see a progress indicator as it works.

    What’s Happening Under the Hood? If you were to open your terminal and run git branch -r, you would see new remote branches created for each of your virtual branches. For example, if you had feature/login-api and feature/login-ui locally, you’d now see origin/feature/login-api and origin/feature/login-ui.

Step 3: Verifying Remote Branches

It’s always good to confirm your work has landed on the remote.

  1. Visit Your Git Host: Open your web browser and navigate to your repository on GitHub, GitLab, Bitbucket, or your self-hosted Git server.

  2. Check the Branches Tab: Look for the “Branches” section of your repository. You should now see the new branches corresponding to your GitButler virtual branches.

    Observation: Notice that these are regular Git branches, just like any other. Your team members can now git fetch and git checkout these branches.

Step 4: Creating Stacked Pull Requests

With your branches on the remote, it’s time to initiate the review process.

  1. Start with the Base Branch: On your Git host, find the lowest branch in your published stack (e.g., refactor/auth-middleware).

  2. Create a Pull Request:

    • Initiate a new pull request for this branch.
    • Crucially, set its target branch to main (or master, or your team’s primary integration branch).
    • Give it a clear title and description.

  3. Move Up the Stack:

    • Next, find the next branch in your stack (e.g., feature/login-api).
    • Create a pull request for this branch.
    • Set its target branch to the previously created remote branch (refactor/auth-middleware). This is the essence of stacked PRs!
    • Repeat this process for all branches in your stack, always targeting the branch immediately below it in the stack.

    GitButler’s Helper Links: GitButler often provides convenient links in its UI to directly open your Git host’s “create pull request” page for a specific published branch. Look for an icon or text like “Create PR” next to a published branch. Clicking this will pre-fill some of the PR details, making the process even smoother.

Step 5: Updating a Published Stack

Work isn’t always linear! You’ll often need to make changes to a virtual branch that’s already been published and has an open PR.

  1. Make Local Changes: In GitButler, switch to the virtual branch you want to modify (e.g., feature/login-api). Make your changes, commit them, and ensure your virtual branch looks correct locally.

  2. Re-Publish: Click the “Publish” button again. GitButler will detect the changes on your local virtual branch and push them to the corresponding remote branch.

    What happens on the Remote? Your open pull request will automatically update with the new commits. If you rebased or reordered commits, GitButler will handle the necessary force push to the remote branch, ensuring the remote history matches your cleaned-up local history. This is one of GitButler’s most powerful features – it manages the complex Git operations so you don’t have to.

Mini-Challenge: Publishing a Nested Stack

Let’s solidify your understanding with a practical challenge.

Challenge:

  1. In your GitButler repository, create a new virtual branch called feat/user-settings. Add a commit with a simple change (e.g., “Add settings page placeholder”).
  2. On top of feat/user-settings, create another virtual branch named feat/user-profile-avatar. Add a commit that simulates adding avatar upload logic.
  3. Publish this two-branch stack to your remote repository.
  4. Verify that both feat/user-settings and feat/user-profile-avatar branches now exist on your Git host.
  5. Create a pull request for feat/user-settings targeting main.
  6. Create a second pull request for feat/user-profile-avatar targeting feat/user-settings.
  7. Go back to GitButler, make a small additional change to feat/user-settings (e.g., “Fix typo on settings page”). Commit it.
  8. Re-publish your stack.
  9. Observe how the feat/user-settings PR on your Git host automatically updates with the new commit.

Hint: Pay close attention to the branch selection when creating your pull requests on your Git host. The target branch is key for stacked PRs!

What to observe/learn: This exercise demonstrates the seamless flow from local GitButler work to remote collaboration, and how GitButler handles updates to published, stacked work. You’ll see how easy it is to keep your PRs fresh even after making further changes to lower branches in your stack.

Common Pitfalls & Troubleshooting

Even with GitButler simplifying things, understanding common scenarios helps.

1. Confusing Virtual Branches with Remote Branches

Pitfall: Thinking that GitButler’s virtual branches are the remote branches. Explanation: GitButler’s virtual branches are a local construct. When you “publish,” GitButler creates or updates conventional Git branches on your remote repository that represent your virtual branches. They are distinct but managed by GitButler to stay in sync. Troubleshooting: Always remember that your team interacts with the remote Git branches, while you interact with local GitButler virtual branches. GitButler acts as the bridge.

2. Unexpected Remote Branch Naming

Pitfall: Your remote branch names don’t match your virtual branch names, or they have unexpected prefixes. Explanation: By default, GitButler uses your virtual branch name as the remote branch name. However, some teams or Git host configurations might have specific naming conventions or automated prefixes. Troubleshooting: Check your GitButler settings (if any advanced remote naming is configured). More commonly, simply be aware of the exact names GitButler pushes to the remote, and use those when creating PRs. If you need to rename a remote branch, you might need to do it manually on your Git host or use git push origin :old-name new-name after renaming locally in GitButler and re-publishing.

3. Merge Conflicts When Creating PRs

Pitfall: You create a PR for your base branch (e.g., refactor/auth-middleware into main), and your Git host reports merge conflicts. Explanation: This means that since you branched off main (or your base branch), changes have been merged into main that conflict with your refactor/auth-middleware branch. This is a common Git scenario. Troubleshooting:

  1. Fetch Latest main: In GitButler, ensure your main branch is up-to-date by clicking the “Fetch” button.
  2. Rebase Your Base Virtual Branch: Switch to your refactor/auth-middleware virtual branch. Then, rebase it onto the latest main. GitButler provides easy ways to do this through its UI (e.g., dragging the branch onto main or using a rebase option). Resolve any conflicts locally within GitButler.
  3. Re-publish: After resolving conflicts and ensuring your local stack is clean, re-publish. GitButler will handle the force push to update the remote branch, and your PR will then reflect the rebased changes and hopefully be conflict-free.

Summary

You’ve now mastered the critical step of integrating your local GitButler workflow with your remote repository!

Here’s a quick recap of the key takeaways:

  • Publishing Stacks: GitButler’s “Publish” action pushes your local virtual branch stacks to your remote repository as conventional Git branches.
  • Stacked Pull Requests: This enables a powerful workflow where you create individual PRs for each logical change in your stack, with each PR targeting the previous one, leading to easier reviews and faster feedback.
  • Seamless Updates: GitButler intelligently manages updates to published branches, handling rebases and force pushes behind the scenes, so your open PRs stay current.
  • Bridging Local and Remote: GitButler acts as a smart layer, allowing you to enjoy flexible local development while seamlessly collaborating with a team using standard Git tools.
