Trevor,
1. Yes, it is threaded MPM.
2. We don't use a lot of other external modules. Here is our full list:
- DBI
- DBD-MySQL
- GD
- GDGraph
- Template-Toolkit
- MIME-Lite
- Digest-SHA
- TimeDate
- Test-Class (developer machine only)
- Log-Log4perl
- Class-Singleton
- Apache-DBI
- Apache-Session
- Session
And here is the method that use clone:
sub filter_empty_modules
{
my ($sectors) = @_;
my $ar = [];
foreach my $sec ( @$sectors )
{
my $sector = clone($sec);
my $modules = [];
foreach my $mod ( @{$$sec{modules}} )
{
my $pages = $$mod{pages} or next;
push(@$modules, $mod) if $$pages{has_program};
}
next if @$modules == 0;
$$sector{modules} = $modules;
push @$ar, $sector;
}
return $ar;
}
The problem with mod_perl env. is that you don't know when the problem
will occur; could be after 100 hits or a thousand hit.
I really appreciate that you are looking into this prob.
Thanks.
