The behavior of Mojo::Server::Daemon and Morbo

[Andrey Khozov]

Hello!

I have an example of a small Mojolicious::Lite and Mango application that works correctly under Mojo::Server::Daemon and does not work under Morbo.

Code (https://gist.github.com/avkhozov/6338504):

#!/usr/bin/perl



use Data::Dumper;

use Mango;



use Mojolicious::Lite;



my $mango = Mango->new;

my $db = $mango->db('test');


get '/' => sub {

        my $self = shift;

        $self->render_later;


        Mojo::IOLoop->delay(

                sub {
                        Mojo::IOLoop->timer(1 => shift->begin);

                },
                sub {

                        $db->stats(shift->begin);

                },
                sub {

                        my ($delay, $err, $stats) = @_;

                        return $self->render(text => $err) if $err;

                        $self->render(text => Dumper $stats);

                }
        );

};



app->start;

Output:

Software:

$ cpanm Mango

Mango is up to date. (0.12)

$ mojo version

CORE

  Perl        (v5.16.3, linux)

  Mojolicious (4.27, Top Hat)

OPTIONAL

  EV 4.0+               (4.15)

  IO::Socket::IP 0.16+  (0.21)

  IO::Socket::SSL 1.75+ (1.87)

As far as I know morbo only restarts Mojo::Server::Daemon when changes to files in certain directories.

Can anyone help me explain the behavior of the application under different servers?

$mango is garbage collected before the first request, since under Morbo app->start doesn't block but return the application instance.

Thank you for the explanation.
