I saw some activity regarding this bug, but wasn't sure of the correct way to work around it. This is the simple application that is seeing this error:

https://github.com/gtaylor/EVE-Market-Data-Relay/blob/master/emdr/daemons/announcer/main.py

stderr shows:

BUG: gevent missed a libzmq recv event on 17!

Given what I have, what is the correct way to avoid this bug? I see something about using a poller, but wasn't sure if that was a fix.

Compiling the python binding under cygwin fails. This may be a problem with zeromq linking to libraries. However, pyzmq brings out the problem.

Environment

• Windows Server 2012 R2 (on EC2)
• Python 2.7.11 and VC++ for Python 27 are installed
• PyPy is downloaded from official site

Note

I've not tried http://zeromq.org/docs:windows-installations because I don't have idea how to build libzmq\builds\msvc\vs2008\libzmq.sln without Visual Studio. (32 bit version of VCBuild.exe doesn't seem to be included in VC++ for Python 27 so it is impossible to complete C:\Windows\Microsoft.NET\Framework\v3.5\MSBuild.exe libzmq\builds\msvc\vs2008\libzmq.sln.)

It would be great if pyzmq could ship binary wheels for linux as well.

@matthew-brett made some with this build script:

https://github.com/matthew-brett/manylinux-builds/blob/master/build_pyzmqs.sh

The result has been uploaded to a rackspace container and can be installed with pip 8.1:

pip install \
    --trusted-host=ccdd0ebb5a931e58c7c5-aae005c4999d7244ac63632f8b80e089.r77.cf2.rackcdn.com \
    --find-links=http://ccdd0ebb5a931e58c7c5-aae005c4999d7244ac63632f8b80e089.r77.cf2.rackcdn.com \
    pyzmq

If you think those wheels are correct, it would be great to upload them to PyPI (for instance with twine).

This adds an rpc subpackage to zmq and implements a "simple" RPC service. This version is focused only on the request/reply pattern, but handles load balancing using ROUTER/DEALER sockets. While we definitely want to explore richer RPC APIs that allow for arbitrary socket types and message patterns, this version is very useful because of its extreme simplicity and good performance..

Still working on:

• Making the serialization approach pluggable. I use pickle now, but will allow json and other approaches.
• Adding an async client example.

Needs review:

• Python3 compliance.
• General API choices.

I have installing libzmq in /home/ericu/local with the --prefix option on its configure script. Pyzmq installs fine under CPython 2.7.5. It does not work under pypy even with the environmental variables set.

I'm running the 32 bit version of python on Windows 7 64-bit Enterprise. When trying to import I get the following error:

15.2.0 works without issue.

Some new APIs and deprecations of old ones that made no sense.

Deprecations

• Stop using POLLERR, and deprecate on_err in ZMQStream, which never did anything because POLLER can never occur on zmq sockets.

New Features

• default socket options can be set as attributes on Contexts. This lets you do ctx.linger = 0 to set the initial LINGER of all subsequently created sockets, and the same with all sockopts.
• ZMQStream.on_recv_stream/on_send_send callbacks, which get the stream as the first argument, in addition to those that were previously passed. Makes it easier to use a single function as the callback for multiple sockets.

Changes

• zmq.Message renamed to zmq.Frame, to better match high-level binding naming conventions. zmq.Message name remains for backwards compatibility.

Cleanup

• Removed some #! lines from module files that are not scripts

libzmq-4.1.2 pyzmq-15.2.0 Python-3.5.1 (default, Dec 7 2015, 21:59:10) [GCC 4.2.1 Compatible Apple LLVM 7.0.0 (clang-700.1.76)]

HWM = 2

According to the docs if you set LINGER to -1, socket.close is supposed to flush out all messages before returning. There are a few issues with this:

1. If socket.close / Context.destroy really were to flush the messages they should return futures
2. they do not actually wait for the the messages to get flushed.

I tried this with several messages of length ~700k and maybe 10% of the time the last two messages were not flushed.

If I add an asyncio.sleep after the term/destroy/close then the messages get flushed

Hi, I installed the last version of pyzmq 24.0.1 and its seems that it contain the draft options, therefore radio and dish are included. I try to run your radio-dish example:

but the following message showed:

Traceback (most recent call last): File "C:/Users/ShacharZ/Desktop/pythonProject2/main.py", line 12, in dish.join('1') File "zmq\backend\cython\socket.pyx", line 722, in zmq.backend.cython.socket.Socket.join File "zmq\backend\cython\checkrc.pxd", line 22, in zmq.backend.cython.checkrc._check_rc zmq.error.Again: Resource temporarily unavailable

I will be happy for any help.

Looking at the documentation, I am seeing that libzmq versions (≥ 3.2.2, ≥ 4.0.1 ) are supported (https://pyzmq.readthedocs.io/en/latest/#supported-libzmq), but am seeing zmq.error.ZMQVersionError: zmq.has requires libzmq >= 4.1, have 4.0.4 on my machine. This is confusing to me, since this fits the constraints of the docs, but is being displayed as an error.

Is this a typo with the documentation or a mischecking by the error? (possibly 4.1.0 was meant, instead of 4.0.1 in the docs?)

Edit: This is pyzmq version 24.0.1 (did not see this error on 24.0.0)
