I'm facing the same problem, though not in a testing situation.
Following Corion's advice, I'm trying to pass the server's PID (returned by its background() method) to a handler that will be responsible for killing it.
My problem is that I can't find a way to pass the PID to the handler.
I've tried several things which all end up the same way when I access the url associated to the handler: the PID's value has not been passed and Perl "Can't kill a non-numeric process ID".
I've tried this (where the setup is maximally contrived for brevity):
A) Store PID as a global in the main package and access it from the server package.
In test.pl:
use strict;
use warnings;
use MyWebServer;
my $server = MyWebServer->new(8080);
our $pid = $server->background();
And in Webserver.pm:
package MyWebServer;
use strict;
use warnings;
use HTTP::Server::Simple::CGI;
use base qw(HTTP::Server::Simple::CGI);
sub handle_request {
kill 9, $main::pid;
}
1;
B) Store PID as a global in the server package and set it in the main package.
In test.pl:
use strict;
use warnings;
use MyWebServer;
my $server = MyWebServer->new(8080);
$MyWebServer::pid = $server->background();
And in Webserver.pm:
package MyWebServer;
use strict;
use warnings;
our $pid;
use HTTP::Server::Simple::CGI;
use base qw(HTTP::Server::Simple::CGI);
sub handle_request {
kill 9, $pid;
}
1;
C) Store the PID in a separate module used by test.pl and webserver.pm.
In test.pl:
use strict;
use warnings;
use Pid;
use MyWebServer;
my $server = MyWebServer->new(8080);
Pid->set($server->background());
In Webserver.pm:
package MyWebServer;
use strict;
use warnings;
use Pid;
use HTTP::Server::Simple::CGI;
use base qw(HTTP::Server::Simple::CGI);
sub handle_request {
kill 9, Pid->get();
}
1;
And in Pid.pm:
package Pid;
use strict;
use warnings;
my $pid;
sub get {
my $package = shift;
return $pid;
}
sub set {
my $package = shift;
$pid = shift;
}
1;
I've tried even more esoteric things until I started to feel like Wile E. Coyote, so I think it's time I submit this problem to you.
Any advice would be welcome, and so would any explanation as to what I fail to understand. |
