RE: File Handle problems - mod_perl 2.0

["Justin Luster" <suppressed>]

Hi,

I agree making it lexically scoped would be better.  I've done that with
all of my other files but this one is used everywhere in the code in a
global manner and would be a lot of work to change.

How would I know if I was using: "threaded httpd MPM"?

Again, it seems to be working just fine under Mod_Perl 1, any idea why
things might be different in Mod_Perl 2?

Thanks,

Justin

quthlib::QUESTIONFILE is certainly a global in disguise, any reason  
you can't change to the lexically scoped
open(my $questionfile, '<', [...]);

and use that instead.

This would only be a *big* problem if you are using a threaded httpd  
MPM with
mod_perl 2.0.
