I always use strict, -w and fatalsToBrowser when developing,
but today this caused me a huge headache in
a simple script (with no syntax errors) that merely reads a
file, formats the contents, and displays the html.
fine from the command line (with a few uninitialized value
warnings) and could save the output with
perl foo.pl > foo.html
but it would just whirl and give no output via CGI. I found that
the code looks and behaves perfectly via CGI unless
-w and fatalsToBrowser are enabled! Shut
either one off (leaving the other on) and it works fine.
I found a certain loop in the program that seems to cause
this by throwing pairs of =cut around, but the loop seems
mundane and similar to the others.
Is this odd interplay between -w and fatalsToBrowser documented?
Update: I said i'd node the entire script to craft
in a day or two but am finding it difficult to abstract a
simplified example. So i'll just suggest that if your
error-free cgi script mysteriously hangs, turning off
either -w or fatalsToBrowser may help.
dws - Try this for a good html :
