Problems profiling with Apache::DProf

[prev] [thread] [next] [Date index for 2005/03/29]

I'm having trouble with Apache::DProf.  Firstly, there seems to be a 
problem with the server_root_relative() method; once that's hacked to 
work, the profiler still doesn't return any useful information.  The 
most I've been able to get it to do is profile what appears to be the 
Apache:: startup information, but not my handler.

Perl 5.8.6, Apache 2.0.53, mod_perl 1.999.21.  The relevant section of 
the httpd.conf:

PerlModule Apache2
PerlModule Apache::DB
PerlModule Apache::DProf

<Location /www>
   SetHandler perl-script
   PerlHandler Controller::Dispatcher
</Location>

I've tried loading Apache::DB and Apache::DProf in an init.pl, as well 
as in a BEGIN block in my handler module -- the best that I get is a 
result that looks like:

Ideas?  Some Big Thing I'm just totally missing?
