Re: [zeromq-dev] Android support in 2.1 master
IIRC, configure should produce an error saying: such and such platform not supported. Take the platform name as reported and create a new section in configure.in, check the sections for other platforms and do something similar. One of the commands there IIRC is to define appropriate ZMQ_HAVE_* macro.

[zeromq-dev] choosing the right 0MQ pattern
Hi all I am newbie and looking for the right 0mq pattern that suits my use case Case (C# / Windows) 9 clients (Alpha) each client per machine(windows) 3 serveurs (VWapServer)-Windows 1 market data feed serveur (FeedServer) provided by Fidessa each VWapServer is connected to Feedserver via OpenAccess connection) an alpha client could talk to any VWapServer. here is the flow. 1- a client sends to VWapSer an order(pricelimit, trade, trading period) 2- the VWapServer forwards this order to the Fesedserver. 3- during the trading period, as soon as a matching trade occurs in the market,it is sent to the VWapServer. 4- the VWapServer calculates the price and volume and sends the result to the Client. NB: a)- the VWapServer will not wait for the end period to send the result to the client, but everytime Fidessa sends a matching trades b)- the client can send 10.000 orders a day c)- an API provided by Fidessa will be used between VWapServer and FeddServer Constrainst: this is a realtime application and information received too late is useless for trader. what I am looking for is the right OMQ pattern to choose. Best regard. ___ zeromq-dev mailing list zeromq-dev@lists.zeromq.org http://lists.zeromq.org/mailman/listinfo/zeromq-dev

Re: [zeromq-dev] Delivering private messages to subscribed clients
I am experiencing an assert waking up from sleep, on windows, which I thought
was fixed in 2.1.7, which is why I upgraded to it.
But it still occurs. Tracing indicates our code does not deliberately call to
reattach the pipes, but it occurs somehow in zeromq.
Does anyone know why?
Xrep.cpp
void zmq::xrep_t::xattach_pipes (reader_t *inpipe_, writer_t *outpipe_,
const blob_t peer_identity_)
{
if (outpipe_) {
outpipe_-set_event_sink (this);
// TODO: What if new connection has same peer identity as the old one?
outpipe_t outpipe = {outpipe_, true};
bool ok = outpipes.insert (outpipes_t::value_type (
peer_identity_, outpipe)).second;
zmq_assert (ok);
if (terminating) {
register_term_acks (1);
outpipe_-terminate ();
}

Re: [zeromq-dev] Strange problem with lua-zmq on Windows
Try the attached C version of those scripts to help narrow down where the problem is. I have only tested the code on Linux, but it should be simple to compile it on Windows. I don't have a Windows system handy (sorry, I am at a conference all week) but I tried reproducing this on a Mac. Here's what I found: Running zmq 2.1.7 and the Neopallium lua-zmq, on OSX 10.7, it still breaks, but at least I get an error this time: Too many open files rc == 0 (mailbox.cpp:375) Abort trap: 6 If I remove the outer loop and just run it for 50 sockets, then I get this: Assertion failed: nbytes == sizeof (command_t) (mailbox.cpp:194) Abort trap: 6 (but weirdly, it seems to actually work, it just prints that out afterward). Here's the great part: I get the exact same results running the C version that Robert Jakabosky posted. That pretty well narrows it down to a ZMQ issue rather than a lua-zmq issue, and we even have a line number now. Cool! ___ zeromq-dev mailing list zeromq-dev@lists.zeromq.org http://lists.zeromq.org/mailman/listinfo/zeromq-dev
