Go Wiki: Commit messages

Commit messages, also known as CL (changelist) descriptions, should be formatted per https://go.dev/doc/contribute#commit_messages. For example,

net/http: handle foo when bar

[longer description here in the body]

Fixes #12345

Notably, for the subject (the first line of description):

For the body (the rest of the description):

Please don’t use alternate GitHub-supported aliases like Close or Resolves instead of Fixes.

To link a commit to an issue without marking it fixed—for example, if the commit is working toward a fix but not yet a complete fix—GitHub requires only that the issue is mentioned by number in the commit message. By convention, Go commits mention this at the bottom of the message using For, where Fixes might be expected, even if the number is also mentioned in the body of the commit message.

For example:

Refactor func Foo.
This will make the handling of <corner case>
shorter and easier to test.

For #12345

It is common in other Git projects to use Updates instead of For, and that is acceptable too, even though it makes little sense (the commit does not update the issue). More precise phrasings are fine too. Don’t be too pedantic in code reviews: it’s not worth asking people to change from Updates or something else to For, or vice versa.


You can roll back a change using the Gerrit Revert button. Gerrit will generate a description for you. Edit the description to add the Gerrit CL number being rolled back next to or instead of the Git revision number.

Do not use the Gerrit UI to create a revert of a revert, as that notifies people right away. Instead, mail it as a new change, and in the description explain that it is a roll forward of CL NNNNNN which was rolled back by CL NNNNNN.

Other repos

For non-“go” repos (“crypto”, “tools”, “net”, etc), the subject is still the name of the package, but you need to fully-qualify the issue number with the GitHub org/repo syntax:

cipher/rot13: add new super secure cipher

Fixes golang/go#1234

Notably, the first line subject should not contain the x/crypto/ prefix. We only do that for the issue tracker.

Non-normative references

GitHub Pull Requests

If you’re using GitHub Pull Requests, your commit message is constructed by GerritBot based on your PR’s title & description. See https://go.dev/wiki/GerritBot#how-does-gerritbot-determine-the-final-commit-message.

If somebody asks you to modify your commit message, you’ll need to modify your PR.
