Support for CGI::Simple in RT 3.8.1

Olly_Stephens1 · November 11, 2008, 1:37pm

I’m currently using FCGI::Engine to provide the RT backend for my new
installation (not live yet). It uses CGI::Simple as its CGI object.
This hasn’t caused any problems thus far but I noticed today that
attachments were not working. Turns out there are subtle differences in
how to deal with uploads.

Attached is a patch to lib/RT/Interface/Web.pm which adds the variations
if it detects that the CGI object is one from CGI::Simple.

It’s only had very basic testing - i.e. I haven’t tried it in a normal
CGI environment to ensure nothing broke. But it’s a relatively simple
patch so should prove no trouble.
