This is a fork of github.com/etcd-io/etcd/clientv3 v3.4.13 to make the client its own separate package compatibile with Go modules, made out of frustration with the upstream project and its handling of modules and GRPC versions seen in the following issues;
etcd-io/etcd#12068
etcd-io/etcd#12124
etcd-io/etcd#12276
etcd-io/etcd#12258
etcd-io/etcd#11707
etcd-io/etcd#11721
etcd-io/etcd#11931
etcd-io/etcd#11563
The code base has been further patched to support the TryLock() function on concurrency.Mutex to allow for non blocking distributed locks from here

It requires your application usage to be fixed to GRPC v1.29.1
The purpose of this fork is to get a working etcd client library that works with Go Modules and uses the most recent version of GRPC possible. This package is meant to be temporary and may become redundant with the release of etcd v3.5 series which aims to refactor clientv3 to work with GRPC 1.30 as seen in the project milestone https://github.com/etcd-io/etcd/milestone/37 in issue etcd-io/etcd#12124
To use this client in your own application.
Require specified GRPC version
go mod edit -replace "google.golang.org/grpc=google.golang.org/grpc@v1.29.1"
Install package
go get -u github.com/swdee/etcdc
Import into your application using a declaration to name as a replacement for upstream clientv3 package.
import (
clientv3 "github.com/swdee/etcdc"
"github.com/swdee/etcdc/concurrency"
)
