Monks,

Firstly, thank you in advance for taking your time to read through my question.

The below `heavily modified` perl code works flawlessly without the call to retr_connected_users. Once I add that subroutine, perl gets hung on the `select` syscall *after* it's first interation through the code. I suspect it has something to do with the `some command` code, and I have tried variations like open/<>/close, but I cannot get past the first iteration.

My question is can AnyEvent effect the underlying file descriptors in a way that would cause this strange behavior and is there any way to read external data from pipes/file descriptors synchronously that perhaps I am just missing entirely?

use AnyEvent::XMPP::Ext::MUC;

sub retr_connected_users {
        my @data = map { chomp; s/@.*//; $_ } (`some command`);
        return @data;
}

$muc->reg_cb(
        message => sub {
                my ( undef, undef, $msg ) = @_;

                my @inter = retr_connected_users();
                foreach my $user(@inter){
                        AnyEvent::XMPP::IM::Message->new (
                                body => construct_body($msg->body, $fr
+om),
                                to   => "$user\@" . HOST,
                                type => "chat",
                        )->send($conn);
                }
        },
);

Thanks for your time.
