Perl 5 implementation of gRPC using the official gRPC shared library.

Grpc::XS / grpc-perl

Overview

This repository contains source code for a perl 5 implementation of gRPC transport layer. It binds to the official shared C library. The implementation is heavily based on the php implementation of the gRPC library.

Usage

This implementation only implements the grpc client, not the server. This library also only implements the transport layer and is not intended to be used directly. Instead it should be used in combination with a protocol buffer implementation that support service rpc definitions. Currently the excellent Google::ProtocolBuffers::Dynamic module is the best option for this.

fork() compatibility

It's possible to fork processes which use Grpc::XS, but only if this library is used exclusively inside child processes. This requires an explicit (de)initialization, otherwise things will hang forever on very first attemp to use anything grpc-related. Here is how it can be done:

Gprc::XS::destroy();
if (fork() == 0) { # in child
	Grpc::XS::init();
	# Grpc::XS can be used in this child without any problems
}
