Apache::SIG kills the process
I was rewriting the detecting 'STOP' button pressed section in the guide,
to notice that Apache::SIG kills the process under Apache::Registry.
httpd.conf:
PerlFixupHandler Apache::SIG
test script:
use strict;
my $r = shift;
$r->send_http_header('text/plain');
print("PID = $$\n");
$r->rflush;
while(1){
$r->print("\0");
$r->rflush;
sleep 1;
}
'STOP' pressed:
alarm(300) = 0
alarm(0) = 300

time([979032041]) = 979032041

_exit(0) = ?
CORE::exit is called internally and the process quits. The trace was
run under httpd -X, but the same happens with normal setup.
Apache/1.3.14 (Unix) mod_perl/1.24_02-dev perl5.6.0 linux (k2.2.17)
Ideas? Thanks!
