Zyre has (since about a day) Python bindings via the zproject generator that Zyre uses. I'm not sure they are 100% complete yet. See latest commits to zproject. Pyre is an interesting alternative. On Sat, Feb 21, 2015 at 11:26 PM, Utsav Drolia utsavdro...@gmail.com wrote: Hi, There is a project

Hi, There is a project - pyre (https://github.com/zeromq/pyre) which is a python implementation of the ZRE protocol. Will zyre directly support python bindings or should one use pyre instead? Thanks! Utsav ___ zeromq-dev mailing list

[zeromq-dev] thread safe sockets and ZMQ_FD

2015-02-21 Thread Thomas Rodgers
It looks like the recently added code for supporting thread safe sockets does not support returning the signalling FD for a socket that is marked thread safe. How would these socket types be used in a polling reactor then? ___ zeromq-dev mailing list

Currently the thread safe sockets doesn't support polling on multiple sockets as stated in the PR: https://github.com/zeromq/libzmq/pull/1349 I'm planning to solve that by epoll like API where you create a poll and then add sockets to it. The poll type will create a file descriptor that will be

You will be able to create a signaler which is a file descriptor, associate it with the socket and add it to the epoll or kqueue On Sat, Feb 21, 2015 at 5:32 PM, Thomas Rodgers rodg...@twrodgers.com wrote: Specifically, something like epoll or kqueues? On Sat, Feb 21, 2015 at 9:27 AM, Thomas

I will hold off until you've fleshed out those details, but it sounds like the API for getting the signaling FD will be different from what everything else uses currently, which means there will be a class of socket types that I will need to special case to support in my bindings. Is there anyway

in addition to not being exception safe, all of the explicit entry and early exit from the mutex is a fully loaded footgun for some future developer working on this code. RAII is a core idiom of C++ and scoped locks/guards are the only sensible and safe way to write this sort of code so that will

Hi all, Be careful with requiring C++11 constructs. Some environments may need to use older compilers. For example, building PyZMQ from source for Python 2.7 (and some early Python 3 releases) requires building with VS2008, which does not support C++11. Cheers, André On Sat, Feb 21, 2015 at

Why would these be not compile-able with newer versions of VC (I believe VS2008 Goes EOL in July of this year)? Note, changing the libzmq to build with -std=c++11 would not change the C89 compatibility of it's public API. On Saturday, February 21, 2015, André Caron andre.l.ca...@gmail.com wrote:
