### Creating commits and writing commit messages

The commit messages that accompany your code changes are an important piece of documentation. Please follow these guidelines when creating commits:

* [Write good commit messages.](https://cbea.ms/git-commit/#seven-rules)

            System.out.println("Commit " + commit + " wrapper: " + wrapperVersion);
            if (!ALLOWED_WRAPPER_VERSION.matcher(wrapperVersion).matches()) {
                System.err.println(
                    "Bad wrapper version " + wrapperVersion + " used in commit " + commit
                        + ". Please rebase your branch to ensure that each commit uses only released Gradle versions in wrapper (GA, RC or milestone)."

        if (args.length != 0) {
            System.err.println("Usage: java CheckBadMerge.java < commits.txt");
            System.exit(2);
        }

        List<String> commits = readCommitsFromStdin();

        try {
            for (String commit : commits) {
                checkCommit(commit);
            }
        } finally {
            THREAD_POOL.shutdown();
        }
    }

- [ ] Write a pull request description that is detailed enough to understand what the pull request does, how, and why.
- [ ] Each commit in the pull request should have a meaningful subject line and body.
  Note that commits might be squashed by a maintainer on merge.
- [ ] Write unit tests that match behavioral changes, where the tests fail if the changes to the runtime are not applied.

They have different levels of permissions and [specific instructions](./management-tasks.md).

Some of the tasks they can perform include:

* Adding labels to PRs.
* Editing PR titles.
* Adding commits on top of PRs to tweak them.
* Mark answers in GitHub Discussions questions, etc.
* Merge some specific types of PRs.

You can see the current team members in [FastAPI People - Team](./fastapi-people.md#team).

/**
 * TeamCity helper script that prints the list of commits in the current PR (one SHA per line).
 *
 * Usage (Java 11+ single-file source execution):
 *   java .teamcity/scripts/FindCommits.java <target_branch_name>
 *
 * Commit range logic:
 * - Uses origin/<target_branch_name> as the target
 * - If HEAD is a merge commit and one parent equals the target SHA, the other parent is treated as PR head
