Running the tests
In order to run the tests, you will need to have the grpcio
, gevent
, and
grpcio-tools
python packages installed. You can install them using
pip
. It is recommended that you use a python virtualenv to do this.
$ virtualenv path/to/virtualenv # to create a virtualenv
$ . path/to/virtualenv/bin/activate # to use an existing virtualenv
$ pip install grpcio-tools gevent
$ pip install grpcio # Need to install grpcio-tools first to avoid a versioning problem
Building GRPC
In order to compile this project, and anything which depends on it, you will need a working installation of the GRPC C core libraries. This library currently uses the 0.15 version range. If you are on OS X, you can install it with homebrew:
brew tap grpc/grpc
brew install grpc
Alternatively, you can build gRPC from source by checking out an appropriate revision of the repository, and installing as follows:
git clone https://github.com/grpc/grpc.git
git checkout release-0_15_1
cd grpc
git submodule update --init
make
sudo make install
Alternatively, using Nix, pass the following expression to nix-build
and point Stack to the build products in the Nix store:
let pkgs = import <nixpkgs> {};
in pkgs.stdenv.mkDerivation rec
{ name = "grpc";
src = pkgs.fetchgit
{ url = "https://github.com/grpc/grpc.git";
rev = "674b30373e2d6a1e26425952805179f8d52a8c00";
sha256 = "05vj48w4h7bn6xyf1wyg2l6psl38h4yz6j1cl0yd2p5h7f5hb3s7";
};
preInstall = "export prefix";
buildInputs =
[ pkgs.darwin.cctools
pkgs.autoconf
pkgs.automake
pkgs.libtool
pkgs.which
pkgs.zlib
pkgs.openssl
];
}
Using the Library
You must compile with -threaded
, because we rely on being able to execute Haskell while blocking on foreign calls to the gRPC library. If not using code generation, the recommended place to start is in the Network.GRPC.HighLevel.Server.Unregistered
module, where serverLoop
provides a handler loop.
