Hello,
I am attempting to write a system which allows output filters to

That doesn't make any sense, Chris. By the end of the
PerlResponseHandler the response is gone and there is nothing to
filter. You can only add it *before* you start sending any data.
Sorry about that. I am attempting to push the output filter handler
before the end of the PerlResponseHandler. The code snippet from
before which is generating the filter objects is run before calling
$r->print().
That's better :)
The fact that you get a segfault is not good, we should take care of
that. regardless you code is incorrect.
I can not seem to get anything to work here except a simple coderef.
This defeats my entire purpose of dynamically pushing filter
handlers, if they can only be a simple subroutine. Is there any
possible way to use an object as a filter handler, or can it only be
a monolithic subroutine code reference?
Filter handlers are very similar to all other mod_perl handlers, so
whatever works for mod_perl handlers works should work for filters.
I haven't tried using objects as filter handlers. May be in a few days
unless someone beats me to it.
Thanks for the response. I will keep tinkering with it over the weekend
to see if I can resolve the seg faults.
I suppose we didn't put enough defense in the code accepting the callback
argument, expecting the user to do the right thing.
