Custom debugger subs and Apache::DB
Hi,
I'm having some trouble working with Apache::DB. I would like to
override the debugger subs DB::DB and DB::sub with my own custom
versions. I tried several tips found on here and clpm, but can't quite
get it to work.
I'm running Perl 5.8.8, mod_perl 2, apache 2.0.55, Freebsd 5.5.
Here's what I'm doing:
# From httpd.conf. Note I've compiled perl so that @INC contains a lib directory
# in my /home where my modules are, and perl and httpd are able to use/require
# those modules.
PerlSetEnv PERL5DB 'require SubTrace.pm'
Perl
use APR::Pool ();
use Apache::DB ();
Apache::DB-init();
/Perl
Location ~ /MyProject/.*cgi$
Options Indexes FollowSymLinks ExecCGI
AllowOverride All
SetHandler perl-script
PerlResponseHandler ModPerl::Registry
PerlOptions +ParseHeaders
PerlFixupHandler +Apache::DB
Order allow,deny
Allow from 127.0.0.1
/Location
#and package SubTrace.pm contains:
package SubTrace;
sub DB::DB {}
sub DB::sub {
if ($DB::sub =~ /^MyModule/ and $DB::sub !~ /DESTROY|CODE/) {
warn DB::sub: $DB::sub, $/;
}
if ( $DB::sub eq 'DESTROY'
or substr($DB::sub, -9) eq '::DESTROY'
or not defined wantarray)
{
$DB::sub;
$DB::ret = undef;
}elsif (wantarray) {
@DB::ret = $DB::sub;
@DB::ret;
}else{
$DB::ret = $DB::sub;
$DB::ret;
}
}
1;
Now for some reason this just blows up when I run 'httpd -X', the
httpd process becomes several hundred megs and the cgi never displays
anything. To make matters worse, I can't just ^C out, because the
debugger has taken over and spits out info that I don't want, so I
have to kill httpd.
I've looked through Apache::DB, and it should be eval'ing what I've
placed in PERL5DB
but instead it goes ahead and loads Apache/perl5db.pl which I don't
want. I don't want an interactive debugger, instead I want to generate
profiling logs based on my custom DB::DB and DB::sub routines. Maybe
there is a setting I overlooked to disable the interactive debugger
and its output in .perldb and maybe I can get Apache::DB to load
.perldb?
Because the process blew up, I also tried not setting the
PerlFixupHandler to Apache::DB and instead wrapped my SubTrace.pm code
in a BEGIN block, and also added $^P |= 1 to turn on the debugger at
compile time.
This seems to work, because I see output in the log file generated by
my DB::sub routine, however, my DB::DB routine does not seem to be
called at all, which was puzzling, so I think debugging is maybe not
enabled.
Thanks in advance for any tips or advice!

I exactly followed the examples in the module's documentation, and apache runs with Apache:Dprof loaded; but I never got an output file to run through dprofpp. I fiddled with it for a while and then gave up because making my own DB::sub() and DB:DB() seemed easier. I'm not doing anything overly fancy and those 2 subs are all I need. And I also am more interested in rolling my own, to understand more about using DB.pm in various ways. Regards, RK
