Yes - I remember struggling with this when I forked CGI:App and
CGI::App::Dispatch to produce CGI::Snapp and CGI::Snapp::Dispatch.
The problem starts with CAP::Dispatch V 2.18 line 406:
$output = $self->_run_app($module, $rm, $local_args_to_new);
which at least tells you the app got as far as starting.
In V 3.07, that's line 405.
Then, in _run_app(), lines 713 .. 716 say:
# otherwise, just pass it up the chain
} else {
die $@;
}
which tells you the code /in this case/ does not call throw_*.
And in V 3.07 that's lines 716 .. 719.
Conclusion: Either way, you're stuffed :-(.
If you don't want to switch to CGI::Snapp etc, or can't, I'd suggest not
relying on that exception code at all.
Rather: Just do what I did with the re-writes: Add logging code at the
start of all the major subs, which will simply if crudely tell you
exactly how far the code is getting before it dies.
