Leopard, CoreFoundation, and exec()

| | Comments (0)
Under Leopard, using Mac::Carbon:

[pudge@bourque ~]$ happening
Running background process /Users/pudge/bin/happening (983)
The process has forked and you cannot use this CoreFoundation functionality safely. You MUST exec().

Apparently, fork-without-exec with CoreFoundation has always been bad. But it is now an exception.

So in the happening program, I had:

$pid = fork;
exit if $pid;

Now I have:

if (!$nofork) {
    $pid = fork;
    exit if $pid;
    exec($0, '-nofork');

YMMV. use.perl.org
