The Go language implementation of gRPC. HTTP/2 based RPC

#gRPC-Go

The Go implementation of gRPC: A high performance, open source, general RPC framework that puts mobile and HTTP/2 first. For more information see the gRPC Quick Start guide.

Installation

To install this package, you need to install Go and setup your Go workspace on your computer. The simplest way to install the library is to run:

$ go get google.golang.org/grpc

Prerequisites

This requires Go 1.5 or later.

Constraints

The grpc package should only depend on standard Go packages and a small number of exceptions. If your contribution introduces new dependencies which are NOT in the list, you need a discussion with gRPC-Go authors and consultants.

Documentation

See API documentation for package and API descriptions and find examples in the examples directory.

Panic around "transport is closing" scenarios

There seems to be a panic under specific conditions:

panic: runtime error: invalid memory address or nil pointer dereference
