Hook scripts

The following events can trigger a hook script:

• commit
• lock
• unlock
• property change

Each of these events can have two actions associated with it: before the execution of the event and after the execution of the event. The commit event can have a third action hooked to it, because of the way Subversion handles new revisions. When a commit starts, it first creates a transaction that can be rolled back in case of failure. If the transaction succeeds, a new revision is created from it and a number is assigned to it. So the commit event can start the following action:

• start-commit - before the transaction is created
• pre-commit - after the transaction is created, but before it is stored as a revision
• post-commit - after the transaction is successfully stored as a revision
