[dancer-users] Executing Hooks in dancer2

17 Sep 2015

      Hello,

I'm having some issues with the hooks, because it seems that runs more than
one time each time that I'm calling from my Dancer2 application.

I have this plugin:

--
package Dancer2::Plugin::MyPluginTest;
use Dancer2::Plugin;

register_hook 'my_new_hook';

register new_function => sub {
 execute_hook 'my_new_hook';
};

register_plugin;
--

And I have this Dancer test application:

--
use strict;
use warnings;

use Test::More;
use Plack::Test;
use HTTP::Request::Common;
{
    package MyTestApp;
    use Dancer2;
    use Dancer2::Plugin::MyPluginTest;

    my $var = 0;

    get '/' => sub {
      new_function;
      $var;
    };

    hook 'my_new_hook' => sub {
      $var++;
      debug "Executing hook -  $var";
    };
};

my $test = Plack::Test->create( MyTestApp->to_app );
my $res  = $test->request( GET '/' );
is( $res->content, '1', 'Var is 1 after one call on  /' );
done_testing();
--

When I run the test, the hook it's executed twice.

[MyTestApp:6554] debug @2015-09-17 08:26:33> Executing hook -  1 in
plugin.pl l. 21
[MyTestApp:6554] debug @2015-09-17 08:26:33> Executing hook -  2 in
plugin.pl l. 21

not ok 1 - Var is 1 after one call on  /
1..1

#   Failed test 'Var is 1 after one call on  /'
#   at plugin.pl line 29.
#          got: '2'
#     expected: '1'
# Looks like you failed 1 test of 1.
Dubious, test returned 1 (wstat 256, 0x100)
Failed 1/1 subtests
--

I just isolate this example of a plugin that I'm working on, but it had the
same problem (but execute the hooks three times).

Any advice?

Thanks in advance.
