Re: [zeromq-dev] Clear socket's cache
On Wed, Feb 15, 2012 at 12:28 PM, Dorin Ciobanu (dciobanu) dciob...@cisco.com wrote: Hi! My application uses a session oriented design. I have a PULL socket in a client app and a PUSH socket in a server app. Sometimes my client app goes away, and I do not know a way to detect this in my server, so I keep sending messages into the PUSH socket (using non-blocking flag). When client application starts, it asks for the queue address from the server app (using a non-ZMQ mechanism). At that moment, I do something to close the old session and initialize a new session, then tell the client the address to connect to for pulling messages. Unfortunately, my client app gets a few “old” messages before getting new ones. What is the best solution for this? Is there a way to “clear the cache” on the socket? Or is there a way to detect a client is no longer connected? I would like to avoid close/bind because it’s a multi-user machine (windows) with concurrent processes that quite actively take and release TCP ports. I could end up with the port occupied by competition and that leads to a whole list of things I have to take care about. Hello, without knowing more about the application here are some options that come into mind: 1. If you can rely on clocks on the client and the server you could timestamp the messages and expire them on the client side if the delivery has taken too long. This would effectively allow you to not process the messages even though they are delivered. 2. Use HWM [1] to limit amount of messages that get pushed into the pipe. For example setting HWM to very low value you should get EAGAIN if the client is not there to receive them. 3. Use a different socket type, such as PUB/SUB where the HWM action is to drop the messages [2]. This is more of a radio broadcast model (which you seem to be after) where messages are delivered to everyone listening and when clients tune off they won't get the messages. Thanks, Mikko [1] http://api.zeromq.org/2-1:zmq-setsockopt#toc3 [2] http://api.zeromq.org/2-1:zmq-socket#toc9 (HWM action) ___ zeromq-dev mailing list zeromq-dev@lists.zeromq.org http://lists.zeromq.org/mailman/listinfo/zeromq-dev

A Ruby binding, for example, should translate some errors back into exceptions. Hello, I don't necessarily agree that the library code should take care of validating every argument passed to it. In your example the ruby binding should take care of the sanity of the arguments passed to lower level or the ruby binding can be built on top of czmq, which does more validation. Adding more validation and cruft on the critical path means additional CPU cycles wasted, which is not desirable in all cases. In my opinion the raw library can and should assume that sane arguments are being passed in and the higher level interfaces (czmq for example) can and should do the validation on top of it if necessary. -- Mikko ___ zeromq-dev mailing list zeromq-dev@lists.zeromq.org http://lists.zeromq.org/mailman/listinfo/zeromq-dev

On Fri, Dec 9, 2011 at 1:02 AM, Yi Ding yi.s.d...@gmail.com wrote: I guess there is a difference in behavior to how ZMQ_FD works and zmq_poll. When using ZMQ_FD I don't even get the signal if I don't call recv first (the timing doesn't matter, I can send out a reply 10 seconds later and I still won't get a notification on the ZMQ_FD unless I've called recv before. just to clarify this further: ZMQ_FD is edge-triggered where as zmq_poll operates on level-triggered way. I tripped on this some time ago as well. ZMQ_FD will only trigger state changes, which means that 3 messages in the pipe will only trigger one POLLIN event and all messages need to be read in the callback in non-blocking fashion. With zmq_poll the POLLIN is triggered as long as there are messages in the pipe so if you don't read the messages in the callback the event will trigger over and over. Another thing is that calling recv on a ZMQ_REQ socket that I've already recv'd from, even if NOBLOCK is enabled, will return EFSM. You should look into ROUTER and DEALER sockets which don't force strict pattern like REQ/REP.

Hi, 2.1 series is currently stable and we cannot change the build files to MSVC10 format (which is not backwards compatible with the earlier versions) in the middle of the cycle. In my opinion stable doesn't mean just the code but also the tools around it including builds. We had a discussions about moving to CMake earlier but I don't think we can give up the autotools due to better cross compilation support. The impression I got from Steven is that CMake is not quite there yet regarding cross builds.

I would suggest that they are removed if this patch or some variant thereof is accepted. Hi, having to maintain multiple sets of Windows build files is the problem indeed. It seems like for each iteration of Visual Studio we need to create another set of project files as the conversion doesn't seem to work as expected (at least import library location is lost during conversion). This is the reason why something like CMake as an abstraction would be a lot more appealing. As far as I understand it's possible to generate Visual Studio project files using CMake. If this works well nothing would prevent us from distributing the project files separately. Does this sound acceptable?

If everything was in a single repository we could finally get rid of manually having to export/merge diff files between directories. Also, at the moment people working on all repositories have to go through three different directories to make sure that git clones are up to date before starting to work on something. Another added benefit of a single repository is being able to follow progress and commits through different branches with more ease.

m_pInprocSocket-setsockopt(ZMQ_SUBSCRIBE, , 0);
Then in thread that opened the SUB socket I want to poll, like:
zmq_pollitem_t pi[] = { m_pInprocSocket, 0, ZMQ_POLLIN, 0 };
Hi,
if you look at the poll examples carefully
(http://zguide.zeromq.org/cpp:mspoller) you need to pass the actual
object to the poll_item_t rather than a pointer to it. Try:
zmq_pollitem_t pi[] = { *m_pInprocSocket, 0, ZMQ_POLLIN, 0 };
thanks,
mikko

Re: [zeromq-dev] too many open files error in zmq/jzmq

Hi all.
What can cause an REQ/REP pair to crash (after doing multiple requests
from Java to C++, crashing both sides at random choice) with following
message:
Too many open files
rc == 0 (mailbox.cpp:375)
(END)
C++ side:
zmq::context_t context (1);
zmq::socket_t socket (context, ZMQ_REP);
socket.bind (tcp:://localhost:1234);
while (true) {
void *context = zmq_init(1);
zmq::message_t *request = new zmq::message_t;
socket.recv (request);
... // parse request, prepare reply: unsigned char data with length dsize
zmq::message_t reply (dsize+1);
memcpy((void *)reply.data(), data, dsize);
memset((void *)reply.data()+dsize, '\0', 1);
socket.send(reply);
}
Hi,
I notice that you are creating a new context in while loop in the C++
code. Is this intentional? I think each context creates at least one
socket for the internal logging, which would cause it to run out of
handles eventually as these contexts are not closed in that piece of
code. The Java side could run out of file handles if you are rapidly
opening and closing large amounts of sockets. It might be better to
create one socket per thread and use it for a longer period.

Re: [zeromq-dev] ZMQ.Poller in Java: how to do timeout check for REQ/REP?
2011/9/6 Igor 'Lo' (И.L.) bombsiteunres...@gmail.com:
Hi all.
I have ZMQ.REP socket sitting in some unstable C++ application, so
Java client (doing ZMQ.REQ) can occasionally hang on socket.recv(),
blocking the application.
What I want is to have a recv() timeout of two seconds, returning an
error if other party didn't either responds all all (TCP error on
connection, adopted via LINGER) or responce time is bigger than 2
seconds (have poll() to timeout after 2 seconds waiting).
Following code does not work (hangs at polling):
package TestPack;
import java.util.ArrayList;
import java.util.List;
import java.io.*;
import java.util.*;
import java.math.BigInteger;
import org.zeromq.ZMQ;
import org.msgpack.*;
class TestPack {
private static void doTest(String tester)
{
byte[] raw = MessagePack.pack(tester);
ZMQ.Context context = ZMQ.context(1);
ZMQ.Socket jsocket = context.socket(ZMQ.REQ);
jsocket.setLinger(0);
jsocket.connect (tcp://localhost:1234);
jsocket.send(raw, 0);
ZMQ.Poller it = context.poller(1);
it.register(jsocket, ZMQ.Poller.POLLIN);
System.out.println(Started polling);
boolean got = false;
it.poll(); // --- hangs here.
System.out.println(Done polling);
if (it.pollin(0)) {
byte[] reply = jsocket.recv(0);
String decode = new String(reply,0,reply.length-1);
System.out.println(decode);
got = true;
}
if (got == false) {
System.out.println(Received nothing);
}
jsocket.close();
}
public static void main(String[] args)
{
doTest(hello world);
}
}
Hi,
try calling setTimeout for the poll in java code. The default
behaviour is to block until there is activity in the socket:

For now, though, there's one that needs some urgent attention: *apparent* queuing of messages on PUB/SUB fan-in despite having HWM set to 1 for both the senders and receivers. I say apparent here to acknowledge that problem is most likely with my implementation, and not ZeroMQ. I can't isolate it on my side, though, and am generally at a loss to explain where it's coming from. We use standard PUB/SUB-bind/connect socket pairs throughout the system, all with HWM set to 1 on both sides. The alleged queuing is apparent at the system endpoint, where messages from all the intermediate processing nodes are collected and displayed as a movie. (For the most part, these messages are small in size; they're JSON representations of bounding boxes). What we are finding, though, is that messages from the fastest intermediate nodes -- also the nodes that are generating the most messages as a consequence of being fast -- tend to lag farther and farther behind messages from slower nodes. My understanding of the HWM semantic is that, when the HWM is reached, new messages will not be queued. That means that the queued messages are not the newest messages. There are good reasons for why this has to be the case. Fine. Still, this growing lag for prolific senders doesn't make any sense to me. The message that I receive at the system endpoint should only be as old as the last zmq_recv from that node. Yet, I am experiencing situations in which one of the intermediate nodes will take a break -- eg, it won't send any messages for a while -- and the endpoint will continue to process old messages from it for a few more minutes. Shouldn't it process JUST ONE message from a node that's taking a break if HWM is 1 on both sides of that socket pair? My secret concern here is that there is some gotcha in the fair-queuing semantics of PUB/SUB pairs that's causing this to manifest itself at the fan-in point. But again, IT'S PROBABLY ME. Any intuition that you guys might be able to share would be greatly appreciated. In the meantime I'll try to cook up a toy example that clearly demonstrates the problem. Cheers!

[zeromq-dev] [PATCH] pkg-config

Has anyone documented their port to another OS so I can follow along and attempt to replicate? Hi, I don't know VxWorks at all but assuming you can cross-compile for it using autotools. In this case you need to setup a cross-compiler toolchain and pass the required options for ./configure script. The daily builds currently cross-compile Windows binaries on Linux using mingw32 and the following configure line: ./configure --target=mingw32 --build=i686-linux --host=i586-mingw32msvc I assume VxWorks would be something similar but I really don't know the platform at all. -- Mikko Koppanen ___ zeromq-dev mailing list zeromq-dev@lists.zeromq.org http://lists.zeromq.org/mailman/listinfo/zeromq-dev

It seems that as part of the upgrade to OpenPGM 5.1.114 in 2.1.3 the build system has been completely reworked and OpenPGM is no longer statically linked into libzmq, but instead is built as a separate shared library. Hi, sorry about this hassle, completely my fault not thinking about recursive make install installing openpgm artifacts as well. OpenPGM is still linked statically using libtool convenience archive, so that .so is not actually used by libzmq.so. There is a fix now for preventing automake from recursing into openpgm build dirs and this has been added to zeromq2-1 today.
