Version Control with Subversion, 2nd Edition
by C. Michael Pilato, Ben Collins-Sussman, Brian W. Fitzpatrick
Name
start-commit — Notification of the beginning of a commit.
Description
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 marshaled back to the
client.
Input Parameter(s)
The command-line arguments passed to the hook program, in order, are:
Repository path
Authenticated username attempting the commit
Colon-separated list of capabilities that a client passes to the server, including
depth,mergeinfo, andlog-revprops(new in Subversion 1.5).
Common uses
Access control (e.g., temporarily lockout commits for some reason); a means to allow access only from clients that have certain capabilities.
