uamqp 0.1.0b4

AMQP 1.0 Client Library for Python

uAMQP for Python

An AMQP 1.0 client library for Python.

Installation

Wheels are provided for most major operating systems, so you can install directly with pip:

$ pip install uamqp

Note that if you’re running Linux, you will need to install the CA Certificate bundle as well:

$ apt-get install ca-certificates

If you are running a Linux distro that does not support ManyLinux1, you can install from source:

$ apt-get update
$ apt-get install -y build-essential libssl-dev uuid-dev cmake libcurl4-openssl-dev pkg-config python3-dev python3-pip
$ pip3 install uamqp --no-binary

Python 2.7 support

Coming soon…

Developer Setup

In order to run the code directly, the Cython extension will need to be build first.

Pre-requisites

• Windows: Setup a build environment.

• Linux: Install dependencies as descriped above in the installation instructions.

• MacOS: Install cmake using Homebrew:

$ brew install cmake

Building the extension

This project has two C library dependencies. They are vendored in this repository in these versions:

• Azure uAMQP for C @ 1.2.0

• Azure C Shared Utility @ 2018-03-07-temp-pod

To build, start by creating a virtual environment and installing the required Python packages:

$ python -m venv env
$ env/Scripts/activate
(env)$ pip install -r dev_requirements.txt

Next, run the build command:

$ python setup.py built_ext --inplace

Tests

The tests can be run from within the virtual environment. The extension must be built first using the instructions above.

(env)$ pytest
