IPC::Transit - A framework for high performance message passing


  use strict;
  use IPC::Transit;
  IPC::Transit::send(qname => 'test', message => { a => 'b' });

  #...the same or a different process on the same machine
  my $message = IPC::Transit::receive(qname => 'test');


This queue framework has the following goals:

This queue framework has the following anti-goals:


send(qname => 'some_queue', message => $hashref, serialize_with => 'some serializer')

This sends $hashref to 'some_queue'. some_queue may be on the local box, or it may be in the same process space as the caller.

This call will block until the destination queue has enough space to handle the serialized message.

The serialize_with argument is optional, and defaults to Data::Dumper. Currently, we are using the module Data::Serializer::Raw; any serialization scheme that module supports can be used here.

NB: there is no need to define the serialization type in receive. It is automatically detected and utilized.

receive(qname => 'some_queue', nonblock => [0|1])

This function fetches a hash reference from 'some_queue' and returns it. By default, it will block until a reference is available. Setting nonblock to a true value will cause this to return immediately with 'undef' is no messages are available.

stat(qname => 'some_queue')

Returns various stats about the passed queue name, per IPC::Msg::stat:

 print Dumper IPC::Transit::stat(qname => 'test');
 $VAR1 = {
          'ctime' => 1335141770,
          'cuid' => 1000,
          'lrpid' => 0,
          'uid' => 1000,
          'lspid' => 0,
          'mode' => 438,
          'qnum' => 0,
          'cgid' => 1000,
          'rtime' => 0,
          'qbytes' => 16384,
          'stime' => 0,
          'gid' => 1000


Return an array of hash references, each containing the information obtained by the stat() call, one entry for each queue on the system.


A zillion other queueing systems.


Cross box delivery.

Much else


Patches, flames, opinions, enhancement ideas are all welcome.

I am not satisfied with not supporting Windows, but it is considered secondary. I am open to the possibility of adding abstractions for this kind of support as long as it doesn't greatly affect the primary goals.
