Well, I'm making some progress, but I'm definitely in over my head with the OO
stuff. :-)
I've drilled down a few levels, inlining one function at a time and commenting
stuff out:
My Component calls $m->redirect()
HTML::Mason::ApacheHandler->redirect calls clear_and_abort()
HTML::Mason::Request->clear_and_abort() calls abort()
HTML::Mason::Request->abort calls throw()
HTML::Mason::Exception::Abort->throw calls SUPER::throw()
HTML::Mason::Exception->throw calls SUPER::throw()
Now we're in Exception::Class::Base->throw(), and the error is still there. My
head is starting to spin from following the inheritance path. I don't quite
understand how E::C::B->throw is supposed to work, but I put some debugging
statements in there and got some more clues.
For your convenience, here's the function with my extra prints to STDERR:
package Exception::Class::Base;
sub throw
{
my $proto = shift;
print STDERR "Exception::Class::Base->throw called with proto=$proto\n";
$proto->rethrow if ref $proto;
print STDERR "calling die($proto->new(",join(', ',@_),"))\n\n";
die $proto->new(@_);
}
Here's what comes out (with a little reformatting for readability):
Exception::Class::Base->throw called with proto=Exception::Class::Base
call die(Exception::Class::Base->new(
aborted_value => 302,
error => 'Request->abort was called'))
Exception::Class::Base->throw called with proto=HTML::Mason::Exception
call die(HTML::Mason::Exception->new(error =>
q[
Operation `.': no method found,
left argument in overloaded package Class::DBI::Object::Has::Been::Deleted,
right argument has no overloaded magic at
/usr/local/share/perl/5.8.7/Devel/StackTrace.pm line 122,
<DATA> line 315.
]
))
Voila! (I think) There's the abort(302), then after that, there's another
exception. The invalidated CDBI object (now of fake
class "Class::DBI::Object::Has::Been::Deleted") is in there causing problems
for StackTrace.
But why? My understanding breaks down completely at this point since I don't
really get E::C::B.
Should die() really be getting called?
How did my component data get all the way in there? Is die() trying to dump
the whole $m object, which I assume contains my (now invalid) object?
Confused but intrigued,
Charlie
