Harmony

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

Installation Requirements

GMP and OpenSSL

brew install gmp
brew install openssl

Dev Environment Setup

The required go version is: go1.12

export GOPATH=$HOME/<path_of_your_choice>

mkdir -p $HOME/<path_of_your_choice>/src/github.com/harmony-one

cd $HOME/<path_of_your_choice>/src/github.com/harmony-one

git clone git@github.com:harmony-one/mcl.git
git clone git@github.com:harmony-one/bls.git
git clone git@github.com:harmony-one/harmony.git

cd harmony

make

Note: make sure to run scripts/install_build_tools.shto make sure build tools are of correct versions.

Build

If you want to bypass the Makefile:

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

Note : Some of our scripts require bash 4.x support, please install bash 4.x on MacOS X.

Build all executables

You can run the script ./scripts/go_executable_build.sh to build all the executables.

Build individual executables

Harmony server / main node:

./scripts/go_executable_build.sh harmony

Wallet:

./scripts/go_executable_build.sh wallet

Tx Generator:

./scripts/go_executable_build.sh txgen

Usage

You may build the src/harmony.go locally and run local test.

Running local test

The debug.sh script calls test/deploy.sh script to create a local environment of Harmony blockchain devnet based on the configuration file. The configuration file configures number of nodes and their IP/Port. The script starts 2 shards and 7 nodes in each shard.

./test/debug.sh

Test local blockchain

source scripts/setup_bls_build_flags.sh
./bin/wallet list
./bin/wallet -p local balances

Terminate the local blockchain

./test/kill_nodes.sh

Testing

Make sure you use the following command and make sure everything passed before submitting your code.

./test/test_before_submit.sh
