Please see http://qpid.apache.org/proton/development.html for the current roadmap.
Developers wishing to work across multiple languages should become familiar with the CMake build system as this will build and run all available tests and code whereas the maven build system only run Java tests.
First you will need to set up your basic build environment with CMake and all prerequisites (see the instructions in INSTALL) so that you can build the full code base.
To setup shell variables for your development environment, you must source the file config.sh from the CMake build directory.
$ cd build $ source config.sh
This file sets the necessary environment variables for Java, for all supported dynamic languages (Python, Perl, Ruby, PHP) and for running the tests.
As a developer on Proton, it is a good idea to build and test with the appropriate dependencies and settings in place so that the complete set of language bindings and implementations are present.
Note that there is a common test suite written in python which will run against both the proton-c and proton-j implementations to help keep them in sync with each other. This can be found under the top level
tests/python directory. This has been integrated into the maven build via Jython (and is hence included in the proton-java ctest suite). When you run the python test suite in Jython, the swig generated cproton doesn't actually exist since it is a C module. Instead, you get the
cproton.py that resides in the Java source tree under
cproton.py and its dependent files serve as a shim that adapts between the Java API and the C API.
To test Proton you should use the CMake build. By default this will invoke the maven tests as well, so the maven prerequisites will additionally be required.
By default the unit tests are run using the system‘s default Python interpreter. However, Proton’s Python language bindings support both versions of the python language (Python 2.x and Python 3.x). These bindings should be tested using both versions of the Python interpreter. CMake makes this possible by automatically running the python unit tests under all versions of python installed on the system.
Developers can ensure that Proton remains compatible with both versions of Python by installing the following prerequisites:
Note: currently CMake only supports multi-Python testing in Linux based environments. Non-Linux developers may skip the following two steps.
Installing both Python2.x and Python3.x and their associated development environments on your system. Most modern Linux distributions support installing Python 2.x and Python 3.x in parallel.
Install the tox Python testing tool, (e.g. for Fedora):
$ yum install python-tox
To run the tests, cd into your build directory and use the following commands:
# to run all the tests, summary mode $ ctest # to list the available testsuites $ ctest -N # to run a single testsuite, verbose output $ ctest -V -R c-engine-tests
Additional packages required for testing the language bindings:
# ruby dependencies $ yum install rubygem-minitest rubygem-rspec rubygem-simplecov # alternatively ruby depedencies on non-RPM based systems $ gem install minitest rspec simplecov
