New commit details page (public beta)

A new version of the commit details page is now available in public beta!

This new page, which is enabled by default, lets you quickly understand and navigate the changes in a commit with improvements to filtering, commenting, and keyboard navigation.

What’s new 🎉

Here are a few of the noteworthy changes:

  • Floating comments: Code comments float over the diff when selected. To select, click on the commenter’s avatar to the right of the line.
  • Comment counts: To help you identify files with comments, the number of comments for a file now appears in the file tree.
  • Keyboard navigation within diffs: You can now navigate around changed lines in the diff using the up and down keys on your keyboard. A new context menu also makes it easier to comment, copy, and select.
  • Quick view switching: Switching between unified and split views no longer reloads the page.
  • Filter by file extension: Easily filter changed files by file extension in the diff to see the content most relevant to you.
  • Filtered out diffs hidden: When filtering the file tree, diffs are filtered as well, allowing you to reduce distraction and see the files you care about most.

View repository pushes on the new activity view

We've now made it easier to understand changes to your repositories with the new activity view. Historically viewing pushes to a repository required contacting GitHub support. This new activity view gives users with read access the ability to self-serve insights to a repository and all of its changes.

You can access the Activity view from the main page of a repository by clicking "Activity" to the right of the list of files.

You can also access the activity view from the Branches page of any repository by clicking on the activity icon.

From the activity view you can sort and filter to find exactly what you are looking for.

Here is an example of how you could use the activity view to find a force push on a particular branch, and then compare the changes to the repository before and after the push:

Admins can require sign off on web-based commits

Organization owners and repository admins can now require developers to sign off on commits made through GitHub's web interface. Also, it is now easier for developers to complete a signoff in the web interface.

Note: Signing off on a commit is different than signing a commit, such as with a GPG key.

Background

The Git command line interface has a --signoff option that developers can use to sign off on their commits. Many open-source organizations require developers to sign off on their changes to affirm compliance with repository rules and licensing. Git's --signoff option appends a specially formatted line to the commit message, as shown here:

Signed-off-by: Mona Lisa <mona@github.com>

This text is what constitutes a signoff. It is often called a “DCO signoff” because the most common signoff agreement is the Developer Certificate of Origin (DCO) from the Linux Foundation.

Challenges

Open-source projects often use pull request checks to block commits from being merged unless they're signed off. Here’s an example of a commit being blocked in the open-source Gradle Profiler repository, which uses the Probot GitHub App to check whether all of a pull request's commits are signed off:

A pull request check that failed because a commit was not signed off

This problem is more likely when committing from GitHub's web interface where Git’s --signoff option isn't available. To sign off there, developers must manually add the Signed-off-by: text to their commit message. That's easy to overlook or misformat, resulting in the commit being blocked from merging. Resolving this situation can be complicated and slow developers down, as shown in these instructions to fix one commit:

Instructions for amending a commit that is not signed off

In the words of one open-source contributor:

🤦 As a pull request reviewer, this is my biggest pain point. If someone forgets to manually sign off on a commit in the web UI, the pull request check fails and the only resolution is to rebase or squash and force push to fix the commit message. Either way, the review history becomes unclear. This is high friction for new and infrequent contributors and people forget.

New signoff capabilities

Organization owners and repository admins can now require developers to sign off on commits made through GitHub's web interface, such as when editing a file or merging a pull request.

Also, it is now easier for developers to complete a signoff in the web interface, resulting in fewer commits being blocked from merging and less time spent resolving blocked commits.

How to enable required signoffs for an organization

Organization owners can configure an organization-level setting to require sign off on commits made through the web interface. To do so, click Settings in an organization that you are an owner of. Next, in the navigation under Code, planning, and automation, select Repository and then Repository defaults. Finally, under Commit signoff choose All repositories to require sign off on web-based commits in all repositories in the organization, as shown below. Alternatively, select No policy to disable the setting so that sign off will not be required unless enabled at the repository level.

How to enable required signoffs for a repository

Repository admins can toggle a similar repository-level setting. To do so, click Settings in a repository that you are an admin of. Next, select General (the default, top-most tab). Then toggle the setting named Require contributors to sign off on web-based commits as shown below. This setting will be overridden by the organization-level setting unless the organization has No policy selected.

GitHub's repository-level setting for requiring sign off on commits made in the web interface

When the setting is enabled, the web interface will inform developers that their action of committing will also constitute signing off, as shown below. Like using Git's --signoff option on the command line, signing off in the web interface will automatically append the Signed-off-by: text to the commit message.

GitHub's web interface for committing will inform developers that they are also signing off when they commit

Other information

Related to this feature, GitHub is planning a Git push policy setting that blocks commits from even entering a repository if they are not signed off. This will apply to commits made in GitHub's web interface or pushed from the Git command line or another Git client.

We appreciate feedback on this and other topics in GitHub's public feedback discussions.

Improved verification of historic Git commit signatures

GitHub will now verify Git commit signatures and show commits as "Verified" even if their public GPG signing keys are expired or revoked (but not compromised). You can also upload GPG keys that are expired or revoked to your GitHub user profile.

Using GPG or S/MIME, you can sign Git commits. These commits are marked "Verified" in GitHub's web interface, giving others confidence that they come from a trusted source because they carry their committer's signature.

GPG keys often expire or are revoked when no longer used. Previously, when a public GPG key stored in a GitHub user profile was expired or revoked, all commits that had ever been signed with that key would be shown as "Unverified" on GitHub. That raised unnecessary concern since the commits were validly signed before their key was expired or revoked. Now, when a user's GPG key expires or is revoked for a reason other than being compromised, GitHub will continue showing commits that were previously signed with that key as "Verified." You can also upload GPG keys that are expired or revoked. Besides maintaining trust in commits’ sources, this allows GPG keys to be added or rotated for greater security without losing the “Verified” status of previously signed commits.

Flag unsigned commits with vigilant mode

To improve security and confidence in the authenticity of your contributions, you can flag commits and tags on GitHub.com that are attributed to you but not signed by you. With vigilant mode enabled (now available in beta), unsigned commits attributed to you are flagged with an Unverified badge. This can alert you and others to potential issues with authenticity.

The author and committer of a Git commit can easily be spoofed. For example, someone can push a commit that claims to be from you, but isn’t. Like showing a passport, committers can increase trust in their commits by signing them with a GPG or S/MIME key. And now, when you enable vigilant mode, commits will be flagged if they’re attributed to you but not signed by you. This raises attention if someone tries to spoof your identity as a committer or author. With vigilant mode enabled, all of your commits and tags are marked with one of three verification statuses: Verified, Partially verified, or Unverified.

Commits and tags are marked with one of three verification statuses

Try it yourself! First, check out how to automatically sign your commits. Then, enable vigilant mode in your account settings:

Vigilant mode in GitHub.com personal account settings

Be sure to enable vigilant mode after you start signing your commits and tags. Once you enable it, any unsigned commits or tags that you push to GitHub.com will be marked "Unverified," including past commits.
