I think this is important. We are using commit message / ChangeLog as a document tied to the change, and we are writing very detailed description to make the intention / design of the change clear and making it as a good document when we read the change via git-blame, bisect, using that header, investigating how it works etc. To make / keep this commit message / ChangeLog helpful, we need review, and I think reviewing of these messages is critical to keep usefulness of them. I think COMMIT_MESSAGE proposal has various good benefits. 1. We can review commit mesasges. 2. In local development, we can commit expected COMMIT_MESSAGE file directly in our tree. We can eventually add more and more detailed information to this file while local development continues, and we can also revert COMMIT_MESSAGE change since it can be commited in the local branch. Commit message is tied to a commit, so editing commit without breaking commit-message is hard (how to revert one change from one commit without rewriting commit message? It requires some git hack). Separate independent COMMIT_MESSAGE file can solve this problem and makes local development easy. 3. This solves the problem how to squash multiple commits in one PR. Merge-queue can just look at this file and use this as a commit message when squashing and landing. This means that, in a PR, we can push multiple small commits in our PR branch. Merge-queue can get canonical COMMIT_MESSAGE when squashing, so keeping one-commit-per-one-PR in the upstream branch is easy. This allows normal git-based development workflow while keeping commit-message format canonical: creating a topic branch, committing many small changes to this branch, creating a PR, and PR gets merged into the upstream as a single commit. -Yusuke > >> Proposal: Have Tools/Scripts/git-webkit setup configure hooks in >> contributors local git repositories to lay down CommitMessages.history files >> on merge, checkout and commit which contain the last 5000 commit messages. >> We can put these in similar places to where ChangeLogs are today, although >> we would likely want them in fewer places because this will increase local >> compute time on many git operations.
