[zeromq-dev] Server freezes when there's no response
I noticed every time I load a page that's making a request to an address, the
server seems to freeze whenever there is no response/data from the address. Is
this a bug or am I doing something wrong here? here's my code:
ZMQ.Context context = new ZMQ.Context(1); ZMQ.Socket socket =
context.Socket(ZMQ.SocketType.DEALER); socket.Connect("address_goes_here");
socket.Recv();

The default LGPL requires that you either (a) use only a dynamic library or (b) release your entire app as (L)GPL. The static linking exception does what it says, it lets you link libzmq into static executables. This was originally required for iOS but also used by people on other systems. Removing this would be damaging to use of 0MQ, and would break the existing contract we have between contributors. Further you cannot remove it for any derived work, only 100% new works. -Pieter ___ zeromq-dev mailing list zeromq-dev@lists.zeromq.org http://lists.zeromq.org/mailman/listinfo/zeromq-dev

The wording seems to be from GNU Classpath exception, which is meant to be combined with GPL projects. Combining it with LGPL project doesn't grant any additional rights AFAICS. IANAL though.

[zeromq-dev] Linking Exception
Hi all, AFAIU the linking exception as defined in COPYING.LESSER is not longer valid because people submit patches under LGPL for the last year or so. Thus, iMatix can't grant any special exceptions. The question remains what is the exception good for anyway. It doesn't seem to grant any special rights that LGPL doesn't grant in the first place. Should we remove it or what?

Re: [zeromq-dev] Configuration cannot find libzmq.so.1?
It's a library that depends on pyzmq. I didn't say so because I didn't realize it was important. Yep, I ran sudo ldconfig after installation. I just tried again, with some modifications, and am getting the same error. I can confirm that the following files exist: /usr/local/lib/libzmq.so /usr/local/lib/libzmq.so.1 /usr/local/lib/libzmq.so.1.0.0 (what's the difference between the three files, by the way?)

To expand a little on Martin's response, binding/connecting to multiple
endpoints is one of the strengths of 0mq.
For example, let's assume you have built a service locator using 0mq for
messaging. You may have "clients" within the same process, on the same box and
on the same LAN that all need to use the locator. The locator *could* utilize
multiple transports to most efficiently process requests.
socket.bind("inproc://service_locator");
socket.bind("ipc:///ipcsockets/service_locator");
socket.bind("tcp://192.168.0.100:12000"); # LAN requests
socket.connect("tcp://192.168.0.105:5000"); # connect to device for WAN requests
Note that you can bind *and* connect the very same socket.

The test in question opens a lot sockets. OSX has a rather low limit for
