start-commit — Notification of the beginning of a commit.


The start-commit hook is run before the commit transaction is even created. It is typically used to decide whether the user has commit privileges at all.

If the start-commit hook program returns a nonzero exit value, the commit is stopped before the commit transaction is even created, and anything printed to stderr is marshalled back to the client.

Input Parameter(s)

The command-line arguments passed to the hook program, in order, are:

  1. Repository path

  2. Authenticated username attempting the commit

  3. Colon-separated list of capabilities that a client passes to the server, including depth, mergeinfo, and log-revprops (new in Subversion 1.5).

Common uses

Access control (e.g., temporarily lock out commits for some reason).

A means to allow access only from clients that have certain capabilities.
