Tracing

I've installed:

perl -MCPAN -e 'install Devel::Trace'

and thought I could just put at the top of the file /usr/libexec/webmin/virtual-server/feature-web.pl:

#!/usr/bin/perl -d:Trace

and then turn on debugging around code that I want traced (so that it shows up in the GUI output during operations that I'm debugging):

$Devel::Trace::TRACE = 1; ... code to be traced ... $Devel::Trace::TRACE = 0;

But, this isn't working. This is the development pattern I use when I want to trace steps in perl normally. What do I need to do to get webmin to recognize it? I did try modifying the shebang of /usr/libexec/webmin/miniserv.pl, but that didn't work.

You'll need to run Perl for the whole miniserv.pl process this way, I suspect, as Webmin does some trickery to run in a single Perl process for most actions for performance reasons.

So, I think you'd need to edit the Webmin startup script to start it with this option. Probably /etc/init.d/webmin or /etc/webmin/start...actually, it looks like you could probably edit /usr/libexec/webmin/miniserv.pl to use this shebang line.
