Linux

For Linux it’s a simple shell script, nothing fancy is needed. If the script ends with a 0 exit value, the commit will work, if it exits non-zero, the commit will fail.

If the path (not an svn-path) to your repository on the server is /opt/myRepo/ then the pre-revprop-change script goes in /opt/myRepo/hooks/. You will find a bunch of templates for hooks in that directory. You need to make your script executable by the user your webserver runs as, because that’s who’s going to run this.

pre-revprop-change

#!/bin/sh
# Set up the list of possible parameters.
REPOS="$1"
REV="$2"
USER="$3"
PROPNAME="$4"
ACTION="$5"

# Allow log modifications
if [ "$ACTION" = "M" -a "$PROPNAME" = "svn:log" ]; then
    exit 0
else
    echo "Changing revision properties other than svn:log is prohibited" >&2
    exit 1
fi

Windows

In Windows the syntax is different because you don’t have a real shell. Instead, you use batch file commands to accomplish the same thing. The logic is pretty much the same because it’s simple.
