Respected Monks,

An upcoming release (MCE::Shared 1.826) continues forward with regards to decreasing memory consumption. In doing so, I took out all the code pertaining to condvar, handle, and queue from inside MCE/Shared/Server.pm and re-factored the bits into MCE/Shared/Condvar.pm, Handle.pm, and Queue.pm respectively. Furthermore, I enabled AUTOLOAD inside MCE/Shared.pm and moved all the sugar-type functions inside it.

For testing, the following script loads the relevant modules and constructs a shared queue.

 use strict;
 use warnings;

 use Prima qw( Application Buttons Label );

#use Parallel::ForkManager;
#use MCE;
#use MCE::Loop;
 use MCE::Hobo;

 use MCE::Shared;

 my $que = MCE::Shared->queue();

#busy loop, review top at OS level, press Ctrl-C to exit
 for ( 1 .. 2e9 ) { 1 }

Q. Why is memory footprint important for MCE::Hobo?

A. I have an add-on module using MCE::Hobo to send-recv data, similar to Parallel::Fork::BossWorkerAsync. Someone has requested this for a long time and decided okay will do it. But first, wanted to reduce memory consumption.

MCE::Shared 1.826 will be released sometimes this week.

Regards, Mario
