post-commit — Notification of a successful commit.
The post-commit hook is run after the transaction is committed and a new revision is created. Most people use this hook to send out descriptive emails about the commit or to notify some other tool (such as an issue tracker) that a commit has happened. Some configurations also use this hook to trigger backup processes.
If the post-commit hook returns a
nonzero exit status, the commit will
not be aborted since it has already
completed. However, anything that the hook printed
stderr will be marshalled back to the
client, making it easier to diagnose hook failures.
The command-line arguments passed to the hook program, in order, are:
Revision number created by the commit
Name of the transaction that has become the revision triggering the post-commit hook.
