CGI-Application sending warnings to browser

Need Help??

Boldra has asked for the wisdom of the Perl Monks concerning the following question:

I have a CGI::Application::FastCGI + TT app which is sending perl warnings to the browser (and breaking the content-headers, resulting in 500s).

The warnings of the sort "use of uninitialized value".

CGI::Carp is used, but only 'fatalsToBrowser', not 'warningsToBrowser'.

It's not an Apache global setting, because other scripts aren't doing this.

What else can cause this? How can I get the warnings to go the apaches error log?

Thanks!

CGI-Application sending warnings to browser

I don't think so :)

That sounds weird, are you sure you're not redirecting STDERR to STDOUT?

Or that warnings aren't enabled globally (like on shebang)?

Turn warnings off? no warnings; or $SIGN{__WARN__}=sub{}; ?

Lets go fishing grep warn CGI-Application-FastCGI-0.02 grep stderr CGI-Application-FastCGI-0.02

grep warn CGI-Application-4.50

grep stderr CGI-Application-4.50

grep warn FCGI-0.74

grep stderr FCGI-0.74

From what I can see above, none of the potential culprits are responsible for what you're seeing, and surely someone would have noticed if FCGI.... were broken so seriously

So CGI::Application is not sending warnings to browser
