ANNOUNCE: Apache::Backhand 0.01

Backhand folks -

I saw the mod_backhand talk at ApacheCon, and was an instant convert. I
thought something like this would be educational for me to write, and
hopefully useful to other backhanders. Just finished a rough draft, which
is uploading to CPAN as we speak. I'd love to hear any thoughts you might
have.

NAME
Apache::Backhand - Bridge between mod_backhand and mod_perl

SYNOPSIS
(in httpd.conf)
PerlModule Apache::Backhand
...
BackhandFromSO libexec/byPerl.so byPerl Package::function

(in Package.pm)
sub function {
my ($r, $s) = @_;
my (@servers) = @{$s};
my $serverstats = Apache::Backhand::load_serverstats();
my $personal_arriba = Apache::Backhand::load_personal_arriba();

# modify @servers...

return(\@servers);
}

(the following constants are also provided...)
Apache::Backhand::MAXSERVERS;
Apache::Backhand::MAXSESSIONSPERSERVER;
Apache::Backhand::SERVER_TIMEOUT;

DESCRIPTION
Apache::Backhand ties mod_perl together with mod_backhand,
in two major ways. First, the Apache::Backhand module
itself provides access to the global and shared state
information provided by mod_backhand (most notably
serverstats). Second, the byPerl C function (which is not
part of the Apache::Backhand module, but is distributed
together with it) allows you to write candidacy functions
in Perl.

David, thanks so much for your contribution. This was of interest by
more that one person at ApacheCon. One question (as I didn't look at
you implementation): does it use the existing perl interpreter in
mod_perl, or does it load an interpreter in each Apache child?

Also, I put a link on the mod_backhand page (down in the Documentation
and Links box.

Thanks again!

Theo et. al. -

It relies heavily on mod_perl, including using the interpreter provided by
mod_perl. Any other way would have been reinventing a lot of wheels (i.e.
access to the request object from perl, etc...)

Take it easy...
