Test komodo source from jl777 branch to make sure all the smartchains sync from scratch properly

Purpose

The purpose of this test is to check if the komodo source from jl777 branch has no issues compiling, all smartchains starts and syncs fully from scratch, no stuck chains. You can use this guide for any branch you want to test, just change the branch name in clone and compile section.

This doc is similar to compiling komodo with an additional verify script. Please make sure you are not testing this in a node with funds. This doc is intended for test nodes/computer. If you have funds in your smartchains please backup your wallet and private key. The information in this doc may change in the future to update.

Steps

  1. Install Dependencies (most needed for the first time)
  2. Clone komodo repo and compile
  3. Create komodo.conf file and clear all smartchains dir from .komodo data dir
  4. Start Smartchains using ./assetchains.old and let them sync (it may take a while)
  5. Verify the smartchains

Details

1. Install dependencies

sudo apt-get update && sudo apt-get upgrade -y
sudo apt-get install build-essential pkg-config libc6-dev m4 g++-multilib autoconf libtool ncurses-dev unzip git python zlib1g-dev wget bsdmainutils automake libboost-all-dev libssl-dev libprotobuf-dev protobuf-compiler libgtest-dev libqt4-dev libqrencode-dev libdb++-dev ntp ntpdate software-properties-common curl libcurl4-gnutls-dev cmake clang libsodium-dev -y

cd ~
git clone https://github.com/jl777/komodo
cd komodo
git checkout jl777
./zcutil/fetch-params.sh
./zcutil/build.sh -j$(nproc)
sudo ln -sf /home/$USER/komodo/src/komodo-cli /usr/local/bin/komodo-cli
sudo ln -sf /home/$USER/komodo/src/komodod /usr/local/bin/komodod
sudo chmod +x /usr/local/bin/komodo-cli
sudo chmod +x /usr/local/bin/komodod

3. Create komodo.conf & clear existing smartchains database and files

Create komodo.conf

cd ~/.komodo
nano komodo.conf

Paste the following content inside the file and save it. Don't forget to change values for rpcuser & rpcpassword.

rpcuser=username
rpcpassword=password
txindex=1
bind=127.0.0.1
rpcbind=127.0.0.1

Remove existing smartchain block database and files

cd ~/.komodo
rm -rf AXO  BEER  BET  BNTN  BOTS  BTCH  CEAL  CHAIN  COQUI  CRYPTO  DEX  DSEC  ETOMIC  HODL  JUMBLR  KV  MESH  MGW  MNZ  MSHARK  NINJA  OOT  PANGEA  PIZZA  PRLPAY  REVS  SUPERNET  WLC

4. Start all smartchains

cd ~/komodo/src
./assetchains.old

Wait for all sync to finish before proceeding to next step. This may take a while depending your hardware and internet connection

5a. Create verify script and get coinlist file

cd ~
wget -qO coinlist https://raw.githubusercontent.com/KomodoPlatform/komodotools/master/webworker01/coinlist
nano verify

Paste the following content into it and save the file

#!/bin/bash

source coinlist
forked=false

for coins in "${coinlist[@]}"; do
    coin=($coins)

    blocks=$(komodo-cli -ac_name=${coin[0]} getinfo | jq .blocks)
    longest=$(komodo-cli -ac_name=${coin[0]} getinfo | jq .longestchain)

    if ((blocks < longest)); then
        forked=true
        printf "\033[0;31m${coin[0]} - Possible fork!\033[0m Blocks $blocks < LongestChain $longest\n"
    else
        echo "${coin[0]} - Blocks $blocks = LongestChain $longest"
    fi
done

if [ "$forked" = false ]; then
    printf "\033[0;32mAll coins are fine\033[0m\n"
fi

change permission of verify script

chmod +x verify

5b. Verify the block height

./verify

Result: The result will be similar to below. At the end of the output you will see All coins are fine.
