Harmony

Build Status gopherbadger-tag-do-not-edit Discord Github Action Go Report Card

General Documentation

https://docs.harmony.one

API Guide

http://api.hmny.io/

Requirements

Go 1.16.3

GMP and OpenSSL

On macOS:

brew install gmp
brew install openssl
sudo ln -sf /usr/local/opt/openssl@1.1 /usr/local/opt/openssl

On Linux (Ubuntu)

sudo apt install libgmp-dev  libssl-dev  make gcc g++

On Linux (Cent OS / Amazon Linux 2)

sudo yum install glibc-static gmp-devel gmp-static openssl-libs openssl-static gcc-c++

Docker (for testing)

On macOS:

brew install --cask docker
open /Applications/Docker.app

On Linux, reference official documentation here.

Bash 4+

For macOS, you can reference this guide. For Linux, you can reference this guide.

Dev Environment

Most repos from harmony-one assumes the GOPATH convention. More information here.

First Install

Clone and set up all of the repos with the following set of commands:

  1. Create the appropriate directories:
mkdir -p $(go env GOPATH)/src/github.com/harmony-one
cd $(go env GOPATH)/src/github.com/harmony-one

If you get 'unknown command' or something along those lines, make sure to install golang first.

  1. Clone this repo & dependent repos.
git clone https://github.com/harmony-one/mcl.git
git clone https://github.com/harmony-one/bls.git
git clone https://github.com/harmony-one/harmony.git
cd harmony
  1. Build the harmony binary & dependent libs
go mod tidy
make

Run bash scripts/install_build_tools.sh to ensure build tools are of correct versions. If you get 'missing go.sum entry for module providing package <package_name>', run go mod tidy.

Dev Docker Image

Included in this repo is a Dockerfile that has a full harmony development environment and comes with emacs, vim, ag, tig and other creature comforts. Most importantly, it already has the go environment with our C/C++ based library dependencies (libbls and mcl) set up correctly for you.

You can build the docker image for yourself with the following commands:

cd $(go env GOPATH)/src/github.com/harmony-one/harmony
make clean
docker build -t harmony .

Then you can start your docker container with the following command:

docker rm harmony # Remove old docker container
docker run --name harmony -it -v "$(go env GOPATH)/src/github.com/harmony-one/harmony:/root/go/src/github.com/harmony-one/harmony" harmony /bin/bash

Note that the harmony repo will be shared between your docker container and your host machine. However, everything else in the docker container will be ephemeral.

If you need to open another shell, just do:

docker exec -it harmony /bin/bash

Learn more about docker here.

Build

The make command should automatically build the Harmony binary & all dependent libs.

However, if you wish to bypass the Makefile, first export the build flags:

export CGO_CFLAGS="-I$GOPATH/src/github.com/harmony-one/bls/include -I$GOPATH/src/github.com/harmony-one/mcl/include -I/usr/local/opt/openssl/include"
export CGO_LDFLAGS="-L$GOPATH/src/github.com/harmony-one/bls/lib -L/usr/local/opt/openssl/lib"
export LD_LIBRARY_PATH=$GOPATH/src/github.com/harmony-one/bls/lib:$GOPATH/src/github.com/harmony-one/mcl/lib:/usr/local/opt/openssl/lib
export LIBRARY_PATH=$LD_LIBRARY_PATH
export DYLD_FALLBACK_LIBRARY_PATH=$LD_LIBRARY_PATH
export GO111MODULE=on

Then you can build all executables with the following command:

bash ./scripts/go_executable_build.sh -S

Reference bash ./scripts/go_executable_build.sh -h for more build options

Debugging

One can start a local network (a.k.a localnet) with your current code using the following command:

make debug

This localnet has 2 shards, with 11 nodes on shard 0 (+1 explorer node) and 10 nodes on shard 0 (+1 explorer node).

The shard 0 endpoint will be on the explorer at http://localhost:9599. The shard 1 endpoint will be on the explorer at http://localhost:9598.

You can view the localnet configuration at /test/configs/local-resharding.txt. The fields for the config are (space-delimited & in order) ip, port, mode, bls_pub_key, and shard (optional).

One can force kill the local network with the following command:

make debug-kill

You can view all make commands with make help

Testing

To keep things consistent, we have a docker image to run all tests. These are the same tests ran on the pull request checks.

Note that all testing docker container binds a couple of ports to the host machine for your convince. The ports are:

  • 9500 - Shard 0 RPC for a validator
  • 9501 - Shard 1 RPC for a validator
  • 9599 - Shard 0 RPC for an explorer
  • 9598 - Shard 1 RPC for an explorer
  • 9799 - Shard 0 Rosetta (for an explorer)
  • 9798 - Shard 1 Rosetta (for an explorer)
  • 9899 - Shard 0 WS for an explorer
  • 9898 - Shard 1 WS for an explorer

This allows you to use curl, hmy CLI, postman, rosetta-cli, etc... on your host machine to play with or probe the localnet that was used for the test.

Go tests

To run this test, do:

make test-go

This test runs the go tests along with go lint, go fmt, go imports, go mod, and go generate checks.

RPC tests

To run this test, do:

make test-rpc

This test starts a localnet (within the Docker container), ensures it reaches a consensus, and runs a series of tests to ensure correct RPC behavior. This test also acts as a preliminary integration test (more through tests are done on the testnets).

The tests ran by this command can be found here.

If you wish to debug further with the localnet after the tests are done, open a new shell and run:

make test-rpc-attach

This will open a shell in the docker container that is running the Node API tests.

Note that the docker container has the Harmony CLI on path, therefore you can use that to debug if needed. For example, one could do hmy blockchain latest-headers to check the current block height of localnet. Reference the documentation for the CLI here for more details & commands.

Rosetta tests

To run this test, do:

make test-rosetta

This test starts a localnet (within the Docker container), ensures it reaches a consensus, and runs the Construction & Data API checks using the rosetta-cli. This test also acts as a preliminary integration test (more through tests are done on the testnets).

The config for this test can be found here & here

Similar to the RPC tests, if you wish to debug further with the localnet after the tests are done, open a new shell and run:

make test-rosetta-attach
