Re: [zeromq-dev] solaris 10 Spart jzmq autogen.sh error
OpenPGM doesn't fair to well as Autoconf 2.59 misses all the C99 bits, presumably why you are recommended to copy the macros in-tree. Preparing with a newer version gets to a certain point and other problems arise. -- Steve-o ___ zeromq-dev mailing list zeromq-dev@lists.zeromq.org http://lists.zeromq.org/mailman/listinfo/zeromq-dev

After lowering the Autoconf version check to 2.59 it still required manual

[zeromq-dev] operator void* on socket_t
Hi On IRC this evening some example code was posted up. which contained zmq::socket_t subscriber(context, ZMQ_SUB); . some time later free (subscriber); It's obviously going to be bad if this ever executes, but the main point is this only compiles because of the operator void * on the socket class. The sooner this can be replaced with a 'handle' method the better. Jon ___ zeromq-dev mailing list zeromq-dev@lists.zeromq.org http://lists.zeromq.org/mailman/listinfo/zeromq-dev
[zeromq-dev] [PATCH] XREP sockets, identity message and HWM
Hi
Found an issue with the identities and XREP sockets with HWM set.
If the pipe is full the socket state needs to be reset before the xsend
method is called again.
There's also a test program which asserted prior to this patch.
On another note, I am not sure the HWM is being honoured correctly at
the moment, but that would require confirmation from Martin S.
I expected the main thread to block at message 5, as that is the HWM.
Thoughts?

You need to produce a dll for the library to be used with JNI. Also, make sure that the dlls produced by compiling zeromq are in your linker's path.

Ion, your patch has a few problems: 1) The define to toggle a static build is not meaningful. Rather than ZMQ_NOT_LIBRARY, use something like ZMQ_STATIC (or even ZMQ_STATIC_WIN32 since ZMQ_STATIC seems a bit too generic identifier). 2) Why are you turning off extern "C" for the API declarations when ZMQ_STATIC is selected? This is almost certainly a bad thing since you do not want C++ linkage for the API functions. 3) You should also provide a patch to integrate ZMQ_STATIC as an option into the MSVC build somehow if this is possible. -mato ___ zeromq-dev mailing list zeromq-dev@lists.zeromq.org http://lists.zeromq.org/mailman/listinfo/zeromq-dev

I would advise against any kind of auto-retry mechanism in clrzmq2; if you don't bubble up the EINTR to the user you will lose any ability to interrupt blocking zmq calls. This will result in the "Ctrl-C is not working" scenario which we had with zmq 2.0 where we did precisely this (ignored EINTR from syscalls). -mato ___ zeromq-dev mailing list zeromq-dev@lists.zeromq.org http://lists.zeromq.org/mailman/listinfo/zeromq-dev

My 2 cents: I am using a pub/sub socket on both sides in order to coordinate the workers/masters. Currently I am only publishing shutdown related stuff there but I will use them for stuff like heartbeats in the future.

You can't.
Btw, your connection string in zmq_bind in invalid.
