Configuring commit squashing for pull requests

The easiest one is to take advantage of Git repository servers like GitHub that typically have this built in within the pull/merge request feature. Usually you just need to tick a box saying you want to squash or to choose squash merge Best Map API for Location-Based Services strategy and you’re good to go. GUI tools like SourceTree or GitKraken offer a similar option. If you select more than one merge method, collaborators can choose which type of merge commit to use when they merge a pull request.

To squash and merge pull requests, you must have write permissions in the repository, and the repository must allow squash merging. Git merge –squash allows you to create a single commit on top of the current branch whose effect is the same as merging another branch. But it won’t produce the merge record, which means your pull-request as result would have no changes, yet won’t be marked as merged!

Level 1 outputs only conflicts, 2 outputs conflicts and file changes. Level 5 and above outputs debugging information. Can be overridden by the GIT_MERGE_VERBOSITY environment variable. During a merge, the working tree files are updated to reflect the result of the merge. Among the changes made to the common ancestor’s version, non-overlapping ones are incorporated in the final result verbatim.

@AlexanderMills, I think you just need a second feature branch . Do the merge –squash from the old to the new one, and then merge the new branch to master. All these benefits NET Framework Wikipedia result in a more maintainable code, less time spent chasing team members to get insights about why that line was changed, and more productivity with less stress.

Should you squash commits or merge them as they are?

But realistically, that’s what you encounter often. Merge.verbosity Controls the amount of output shown by the recursive merge strategy. Level 0 outputs nothing except a final error message if conflicts were detected.

  • As previously discussed, another benefit of squash merges is that they prevent noisy source control history which can include typo fixes, previously accidentally missed files, etc.
  • Pull requests in this situation will be marked as merged even if branch protection rules have not been satisfied.
  • For more information about git rebase, see git-rebase in the Git documentation.
  • Without the visual context offered by GitKraken, squashing all of the commits in a branch can be complex in the CLI.
  • The only clean-ups you need are to reset the index file to the HEAD commit to reverse 2.

I think that factors such as team size and how the source history is used should be considered before picking an approach. For example, I am much less inclined to use squash merges on the repository for this site as I am the only developer. However, at times I have squash merged when I’ve had many commits with messages I didn’t want in the source control.

Git Squash Commits

Merging is a safe option that preserves the entire history of your repository, while rebasing creates a linear history by moving your feature branch onto the tip of main. On the other hand, this also means that the feature branch will have an extraneous merge commit every time you need to incorporate upstream changes. If main is very active, this can pollute your feature branch’s history quite a bit.

When set to false, this variable tells Git to create an extra merge commit in such a case (equivalent to giving the –no-ff option from the command line). When set to only, only such fast-forward merges are allowed (equivalent to giving the –ff-only option from the command line). Optionally, under Allow squash merging, use the dropdown to choose the format of the default squash commit message presented to contributors when merging. The default message uses the commit title and message if the pull request contains only 1 commit, or the pull request title and list of commits if the pull request contains 2 or more commits. You can also choose to use just the pull request title, the pull request title and commit details, or the pull request title and description.

When there is no merge.suppressDest variable defined, the default value of master is used for backward compatibility. Theirs This is the opposite of ours; note that, unlike ours, there is no theirs merge strategy to confuse this merge option with. This should not be confused with the ours merge strategy, which does not even look at what the other tree contains at all. It discards everything the other tree did, declaring our history contains all that happened in it.

Recursive strategy

The rebase option is usually considered to be the dangerous one, as you can lose commits or change everything in a way you didn’t intend. Despite this, it’s the one I prefer, and it gives you total control over the actions you need to perform. In a typical team environment with code reviews, you often see small commits with messages like fix xyz or update according to code review.

This was the default strategy for resolving two heads from Git v0.99.9k until v2.33.0. When you select the Rebase and merge option on a pull request on, all commits from the topic branch are added onto the base branch individually without a merge commit. In that way, the rebase and merge behavior resembles Python-Crash-Course Python101 a fast-forward merge by maintaining a linear project history. However, rebasing achieves this by re-writing the commit history on the base branch with new commits. Under “Pull Requests”, select Allow squash merging. This allows contributors to merge a pull request by squashing all commits into a single commit.

git squash and merge

Assume the name of the branch where you made multiple commits is called bugfix/123, and you want to squash these commits. All the other responses seem to assume that nothing has changed in the remote release branch since the last time you were hanging out on it…. That’s if you want to do it one branch at a time. Technically there are ways to rewrite the history, but there are several reasons you generally don’t want to do it. For the sake of simplicity, let’s say the farther the commit is in the repository history, the more complicated it is to rewrite it. Pedro has been working in the software engineering world since starting his career in August 2017.

I recommend to read the pages related to rebasing on Git-SCM. @Sebi2020 git merge –squash will rebase your already published commits in a way that’s worse than an interactive rebase. An interactive rebase carry little to no adverse effects. We reduced the number of fixme, fix previous commit, fix specs commits to the repository. Mistakes happen, and the developer has full freedom to experiment, and even commit incomplete changesets in a branch with the full confidence that, once merged, only the final result will be shown. In fact, to prevent issues with teammates and continuous intgration tools, we explicitly forbid rebasing your commits after you’ve pushed them.

Interactive Rebase Approach

By default, the git pull command performs a merge, but you can force it to integrate the remote branch with a rebase by passing it the –rebase option. Note that this rebase doesn’t violate the Golden Rule of Rebasing because only your local feature commits are being moved—everything before that is untouched. This is like saying, “add my changes to what John has already done.” In most circumstances, this is more intuitive than synchronizing with the remote branch via a merge commit.

Squashing and merging a long-running branch

Git Squash is a Git feature that allows a dev to simplify the Git tree by merging sequential commits into one another. Basically, you start by choosing a base commit and merging all changes from the next commits into this one. This essentially makes it the same as having all the changes you made in several commits in just one commit—the base commit. If all of the above conditions are met, you will see an option to Git squash commits by right-clicking on the commit node after selecting the commits you wish to squash. Without the visual context offered by GitKraken, squashing all of the commits in a branch can be complex in the CLI. GitKraken gives you more control when performing advanced Git actions.
