We definitely welcome patches and contribution to grpc! Here is some guideline and information about how to do so.
In order to protect both you and ourselves, you will need to sign the Contributor License Agreement.
You will need several tools to work with this repository. In addition to all of
the packages described in the INSTALL file, you will also need
python, and the mako template renderer. To install the latter, using pip, one
should simply be able to do pip install mako.
In order to run all of the tests we provide, you will need valgrind and clang. More specifically, under debian, you will need the package libc++-dev to properly run all the tests.
If you are planning to work on any of the languages other than C and C++, you will also need their appropriate development environments.
If you want to work under Windows, we recommend the use of Visual Studio 2013. The Community or Express editions are free and suitable for developing with grpc. Note however that our test environment and tools are available for Unix environments only at the moment.
We provide a tool to help run the suite of tests in various environments. In order to run most of the available tests, one would need to run:
./tools/run_tests/run_tests.py
If you want to run all the possible tests for any of the languages {c, c++, node, php, python}, do this:
./tools/run_tests/run_tests.py -l <lang> -c all
Each language uses its own build system to work. Currently, the root's Makefile and the Visual Studio project files are building only the C and C++ source code. In order to ease the maintenance of these files, we have a template system. Please do not contribute manual changes to any of the generated files. Instead, modify the template files, or the build.json file, and re-generate the project files using the following command:
./tools/buildgen/generate_projects.sh
