Lightcone Relayer 1.0

This relayer is implemented to support Loopring Protocol 2.x. A new version is being worked on for Loopring Protocol 3.0.

Compile

• Compile all, run sbt test:compile

• Remove all unused imports, run sbt fix

• Compile subproject, run sbt $projectName/test:compile

Make sure to use test:compile instead of compile so all tests compile.

• Before committing to git, use sbt check.
• Check scala styles for optimization and refactoring, use sbt scapegoat.

Dockerize

You must have Docker and Docker-Compose installed.

• To create a docker image file for the runnable program (in subproject relayer), run sbt docker. A docker image with name "org.loopring/lightcone_relayer:latest" will be generated.
• To publish the docker image, use sbt dockerPush.
• To run in docker, run docker run --add-host mysql-host:xx.xx.xx.xx --add-host ethereum-host:xx.xx.xx.xx -P -v /xxx/log:/log --shm-size 358716160 -d org.loopring/lightcone_relayer:latest
• To run in docker-compose, run docker-compose up --scale worker=3

Test

• You need to install docker to run all tests
• To run tests under specific subproject, run sbt $projectName/test
• To run only modified and failed tests, run sbt testQuick
• To generate test coverage report, run sbt coverageReport
