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 to stderr will be marshaled back to the
client, making it easier to diagnose hook failures.
