           Summary: Glib::Child->watch_add run exception handlers
           Product: gnome-perl
           Version: unspecified
          Platform: Other
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: Glib
        AssignedTo: gtk...@li...
        ReportedBy: us...@zi...
         QAContact: gtk...@li...
     GNOME version: Unspecified
   GNOME milestone: Unspecified


The subprocess termination handler as setup by Glib::Child->watch_add could
helpfully trap errors to the Glib->install_exception_handler mechanism, the
same way idle, timeout and IO handlers work under a main loop.

(The difference being GPerlCallback instead of the GClosure stuff.)


use Glib;
use strict;
use warnings;

my $pid = fork();
if ($pid == 0) { sleep 1; exit 0 };

Glib->install_exception_handler (sub {
                                   print "exception trapped\n";
                                   return 1;
                                 });

Glib::Child->watch_add ($pid, sub {
                          print "child process stopped\n";
                          die "now throw an error";
                        });

my $mainloop = Glib::MainLoop->new;
$mainloop->run;
