 why are you using Apache::SIG at all?  its no longer required as of
 1.3.6-ish.  if the client goes away writes are noops,  you can test
 $r-connection-aborted if you want to know the client has gone away.

I know that :)

But it still might be useful for:

1. Those who have a huge code base and want an external solution instead
going to fish in the code and place the checking code.

2. Those who need mod_cgi back compatibility (and there are many who needs
that) (of course they can use if $ENV{MOD_PERL} but still they have to
find all the right place to plug the checking.

Apache::SIG kills the process

2001-01-09 Thread Stas Bekman 

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:

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!
