I'm attempting to write an IM client using Ncurses and xmpp4r - I
understood xmpp4r was threaded and event-based, using threaded
callbacks for events such as message reception... but somehow,
Ncurses's input loop is blocking xmpp4r (or so it is as far as I can
tell).
When I have Ncurses waiting for input (via `Ncurses::getch()`), my
`#add_message_callback` block (which currently, for testing purposes,
contains a simple `system 'say "message received"'` system call) isn't
being executed when I send a message from my testing target to the
xmpp4r client.
However, when `Ncurses::getch()` cycles, I get the first of any
messages I've sent - and I get one more message every time it cycles.
I have no idea what's causing this, or blocking the thread, or
whatever - I'd really appreciate any help! I've been banging my head
against this for days now, and I'm running out of patience )-:
*Postscript*: It's worth noting that I don't think it's the callback
that is the problem - I have xmpp4r debugging enabled, and there
doesn't appear to be any reception of stream data in between `::getch`
cycles. The data is actually processed as soon as it's received, it is
just received in a messed up one-message-per-`::getch`-cycle way.
