How do I create a pre-op clearcase trigger that prevents delivery to a specific stream

Question

I have worked with ClearCase triggers in the past but it have been over ten years ago.

I want to make a pre-op trigger which prevents a delivery to a specific stream except for specific users.

I know I can use nusers to allow only certain users to bypass the trigger, but with the opkind do I specify deliver or deliver_start?

For identifying the specific stream, do I write a Perl script that checks for the name, or is there a way I can use the restriction-list or the inclusion-list?

Answer 1

This "Delivery preoperation trigger script" is an official example which could give you some clues on how to write your own (in Perl).

You can see in it how its gets the stream name

use Config;

my $PVOBTAG;
my $tempfile;
my $exit_value;

if ($Config{'osname'} eq 'MSWin32') {
   $PVOBTAG = '\cyclone-pvob';
   $tempfile = $ENV{TMP}."\\expreop.".$ENV{"CLEARCASE_PPID"}.".txt";
}
else {
   $PVOBTAG = '';
}

my $STREAM = "stream:".$ENV{"CLEARCASE_STREAM"};
my $ATTYPE = "attype:deliver_in_progress\@$PVOBTAG";

print $STREAM."\n";
print $ATTYPE."\n";
