Actually, debugging handlers is pretty easy. Just run httpd with the -X flag
to make it single process, and use Apache::DB to get mod_perl to run under
the debugger. Get Apache::DB from CPAN
perl -MCPAN -e 'install Apache::DB'
and read its docs
perldoc Apache::DB
When Apache hits your Perl code, you are dropped into the standard Perl
debugger. Although typing '?' at the debug prompt shows a bewildering array
of options, you can do a lot by knowing:
n - Step over
s - Step into
x <expr> - Print the value of <expr>
w - Show a few lines either side of the current one
b <sub> - break at <sub>
c - continue (stop debugging)
c <line#> - continue, and break at <line#>
HTH,
Jeremy
