If not, then what is the correct way to maintain a connection, react to incoming data, and send data over a TCP connection?
Thanks... (16 Replies)

coro::select
Select(3pm) User Contributed Perl Documentation Select(3pm)NAME
Coro::Select - a (slow but coro-aware) replacement for CORE::select
SYNOPSIS
use Coro::Select; # replace select globally (be careful, see below)
use Core::Select 'select'; # only in this module
use Coro::Select (); # use Coro::Select::select
DESCRIPTION
This module tries to create a fully working replacement for perl's "select" built-in, using "AnyEvent" watchers to do the job, so other
threads can run in parallel to any select user. As many libraries that only have a blocking API do not use global variables and often use
select (or IO::Select), this effectively makes most such libraries "somewhat" non-blocking w.r.t. other threads.
This implementation works fastest when only very few bits are set in the fd set(s).
To be effective globally, this module must be "use"'d before any other module that uses "select", so it should generally be the first
module "use"'d in the main program. Note that overriding "select" globally might actually cause problems, as some "AnyEvent" backends use
"select" themselves, and asking AnyEvent to use Coro::Select, which in turn asks AnyEvent will not quite work.
You can also invoke it from the commandline as "perl -MCoro::Select".
To override select only for a single module (e.g. "Net::DBus::Reactor"), use a code fragment like this to load it:
{
package Net::DBus::Reactor;
use Coro::Select qw(select);
use Net::DBus::Reactor;
}
Some modules (notably POE::Loop::Select) directly call "CORE::select". For these modules, we need to patch the opcode table by sandwiching
it between calls to "Coro::Select::patch_pp_sselect" and "Coro::Select::unpatch_pp_sselect":
BEGIN {
use Coro::Select ();
Coro::Select::patch_pp_sselect;
require evil_poe_module_using_CORE::SELECT;
Coro::Select::unpatch_pp_sselect;
}
BUGS
For performance reasons, Coro::Select's select function might not properly detect bad file descriptors (but relying on EBADF is inherently
non-portable).
