Last week, I asked whether you should include issue IDs in commit messages<\/a>.<\/p>\n\n

Another thing I like to reference in a commit message is the commit ID (or SHA) of a related commit.<\/p>\n\n

For example, when I run git log<\/code> in my website repository, I see commits like this:<\/p>\n\n

commit 0c91825c16217d0fe7eff4ea100a67550051c4a9\nAuthor: Oliver Davies <oliver@oliverdavies.dev>\nDate:   Sat May 11 15:32:07 2024 +0200\n\n    Create a cached talk counter\n\n    Create a cached version of the talk counter service that returns a\n    cached result of the talk count for that day.\n\n    This uses the Decorator design pattern to decorate the existing\n    `TalkCounter` service and works as they both implement the same\n    `TalkCounterInterface`.\n<\/code><\/pre>\n\n

The sha for this commit is 0c91825c16217d0fe7eff4ea100a67550051c4a9<\/code>.<\/p>\n\n

If I was to make another commit that was related to this one, I can include this commit sha in my new commit message.<\/p>\n\n

I also don't need to include the entire thing - only enough for it to be unique (usually five or six characters).<\/p>\n\n

Once pushed, the commit IDs should never change, so this will be a permanent reference to the first commit.<\/p>\n\n

Helpfully, websites like GitHub, GitLab and Bitbucket will identify it as a commit sha and make it clickable so you can easily navigate to the referenced commit.<\/p>\n\n ", "format": "full_html", "processed": "\n
