Thanks for the tip, pemungkah!

The other problem is how to get the -d:Trace option to work under mod_perl.

Here's how to do it:

Add the following section to httpd.conf:

<Perl> $Devel::Trace::TRACE = 0; </Perl>

And start the server like this:

$ PERL5OPT=-d:Trace sudo /etc/init.d/httpd restart

Then in your code you can write:

$Devel::Trace::TRACE = 1; # some buggy code $Devel::Trace::TRACE = 0;

Problems:

  • Server spits out a mess of trace info before $TRACE is set to 0
  • Trace info (and there's a lot of it) goes to the error log, which is hard to manage

I think I'll try making a patch to allow turning off $TRACE via the command line, and to allow sending the trace info to a different file.
