[Catalyst] Debugging Catalyst with Komodo

[Dan Dascalescu]

I'm running Catalyst 5.7006 on RHEL AS 4 and want to debug remotely
with Komodo 4.0.0-beta4 on a Windows box. The problem is Komodo can
only step through the initialization pars of the app, and execution
never reaches breakpoints in controllers.

I made sure first that debugging worked. On the RHEL box, I ran:
catalyst.pl myapp
myapp/script/myapp_create.pl controller Test

Then I edited Test.pm and inserted a $DB::single = 1; before the
"Matched myapp::Controller::Test" lines. Debugging with "perl -d
script/myapp_server.pl" , 'c' works okay: execution stops just before
$c->response->body('Matched myapp::Controller::Test in Test.');

Next, I set per Komodo's documentation, the following environment variables:
export PERL5LIB=/<absolute_path_to>/KomodoPerlRemoteDebugging
export PERLDB_OPTS=RemotePort=<IP of Windows box>:9000

"perl -d script/myapp_server.pl" also works, in the sense that Komodo
fires up and lets me single-step through the code.

The issue is that if I put a breakpoint in Test.pm on the "Matched..."
line, and press F5 to continue running the script, myapp_server.pl
exists.

I single-stepped through the code in Komodo until I found the exit
point. It's in Catalyst::Engine::HTTP.pm, in the run() sub. The loop

    while ( accept( Remote, $daemon ) )
    {    # TODO: get while ( my $remote = $daemon->accept ) to work

is never entered. Execution skips to $daemon->close; and that's it.


At this point, I'm afraid I'm out of ideas... Kieren suggested that I
ask on both mailing lists.

Is this an issue with Catalyst, or Komodo?
Does anyone know of a work-around?
As a last resort, another IDE debugger?

Any help is much appreciated. Thanks,
Dan
