# This is the core script that verifies file permission when a user checks
# in a file in CVS.  This script should called when a file is committed to
# CVS.  This can be achieved by deploying this script in the commitinfo file
# of the repository.

#Assumptions
#------------
#The command line will contain the name of the path that should be verified (typically the $1 in commitinfo script)
#The CVS server uses OS user as the authentication mechanism (SystemAuth=yes)
#We are being called during commit time.


grep "^$USER\$" $CVSROOT/CVSROOT/users.restricted  >/dev/null
#if this is a restricted user then check further.  Otherwise dont bother.
if [ $? -eq 0 ];then
    #This person we have to check
	echo $1 | grep -f `echo $CVSROOT/CVSROOT/$USER.permission`  >/dev/null 2>&1
	RESULT=$?
	if [ $RESULT -eq 0 ];then
		#Has permission -  It is OK to allow him to commit the file.
		exit 0;
	elif [ $RESULT -eq 2 ];then
		echo $USER you are not setup correctly for CVS permissions.  Please contact the CVS Admin.
		exit 1;
	else
		echo "sorry! $USER does not have permission to commit file(s) $1"
		exit 1;
