[Q][LONG] using IPC::Shareable to cache data, Apache doesnt start

[Juan Natera]

Hello everyone,

I am trying to use a IPC::Shareable tied hash to cache some data at the 
start of apache from my startup.pl script.

this is my startup.pl

-
$ENV{GATEWAY_INTERFACE} =~ /^CGI-Perl/ or
die GATEWAY_INTERFACE not Perl!;

use Apache::Registry;
use Apache::DBI;
use IPC::Shareable;
use GXV::Abonados;
use strict;

my %GLOBALDATA;
my %options = (
 create= 1,
 exclusive = 0,
 mode  = 0666,
 destroy   = 1,
);

tie %GLOBALDATA, 'IPC::Shareable', 'GLUE', { %options } ||
die tie failed\n;

my $gxv = GXV::Abonados-new ||
die not able to connect to GXV\n;

eval {
 %GLOBALDATA = $gxv-paquetes_shared;
};

die Global data is not accessible: $ if ($);
1;
--


The method GXV::Abonados::paquetes_shared() works, I have tried many 
forms of recieving (and returning of course) the data (a flat scalar, 
arrays, hashes).

If I asign to *GLOBALDATA a short string or number it works, I checked 
IPC::Shareable::SHM_BUFSIZ(); and it's more than enough to hold the 
return value of $gxv-paquetes_shared;

The worst of all is that Apache simply doesnt start, and I get no error 
message at all.

Can someone please give me some insight?

TIA,

Best Regards,

Juan Jose Natera

The error might be on the console, or you could try capturing it and 
writing it to a file.  However, I suggest you ditch IPC::Shareable since 
it's dog slow.  Use MLDBM::Sync, Cache::FileCache, IPC::MM, or Cache::Mmap.
