cargo install --force cargo-make

runs all unit tests, worker executor tests and integration tests

cargo make test

runs unit tests only

cargo make unit-tests

runs worker executor tests only

cargo make integration-tests

runs CLI tests only

cargo make cli-tests

runs sharding integration tests only

cargo make sharding-tests

Running Benchmarks

  1. Raise PR
  2. Reviewer or author of PR can run benchmarks by typing in a PR comment as follows
    /run-benchmark
  1. For all new benchmark types (meaning, those for which there is no baseline to compare), it should generate a report as below, as a PR comment

Benchmark Report

benchmark_cold_start_large.json 3 10 100 201.255108ms

RunID: 9435476881

  1. The underlying data used to created the above report will be automatically pushed back to the PR branch
  2. If there exists a baseline to compare for the benchmark type, then a comparison report will be generated for those benchmarks
  3. If there is no need to compare with any baseline, regardless of a baseline exist or not, then simply run
/run-benchmark-refresh
  1. Refresh message can be useful in the event of comparison failures (Example: A failure due to schema mismatch especially when a developer refactor the benchmark code itself)

Starting all services locally

There is a simple cargo make run task that starts all the debug executables of the services locally, using the default configuration. The prerequisites are:

  • nginx installed (on OSX can be installed with brew install nginx)
  • redis installed (on OSX can be installed with brew install redis)
  • lnav installed (on OSX can be installed with brew install lnav)

The cargo make run command will start all the services and show a unified view of the logs using lnav. Quitting lnav kills the spawned processes.

Local Testing using Docker containers

To spin up services using the latest code

# Clone golem
cd golem

# Find more info below if you are having issues running this command(example: Running from MAC may fail)
# Target has to be x86_64-unknown-linux-gnu or aarch64-unknown-linux-gnu-gcc
cargo build --release --target x86_64-unknown-linux-gnu

docker compose -f docker-compose-sqlite.yaml up --build

To start the service without a rebuild

docker compose -f docker-compose-sqlite.yaml up

To compose down,

docker compose -f docker-compose-sqlite.yaml down

To compose down including persistence volume

docker compose -f docker-compose-sqlite.yaml down -v

Note that, if you are using MAC, the persistence volumes may be present in the Linux VM. You can inspect this using the following command:

docker run -it --rm --privileged --pid=host alpine:latest nsenter -t 1 -m -u -n -i sh

# As an example: cd /var/lib/docker/volumes/golem-services_redis_data/_data
/var/lib/docker/volumes/golem-services_redis_data/_data # ls -lrt
total 4
-rw-------    1 999      ping          3519 Jan 19 02:32 dump.rdb
/var/lib/docker/volumes/golem-services_redis_data/_data #

If you have issues running the above cargo build command, then read on:

Make sure to do docker-compose pull next time to make sure you are pulling the latest images than the cached ones

Cargo Build

MAC

If you are running cargo build --target ARCH-unknown-linux-gnu (cross compiling to Linux) from MAC, you may encounter some missing dependencies. If interested, refer, https://github.com/messense/homebrew-macos-cross-toolchains

Intel MAC

Typically, the following should allow you to run it successfully.

brew tap messense/macos-cross-toolchains
brew install messense/macos-cross-toolchains/x86_64-unknown-linux-gnu
# If openssl is not in system
# brew install openssl
export OPENSSL_DIR=$(brew --prefix openssl)

export CXX_X86_64_UNKNOWN_LINUX_GNU=x86_64-unknown-linux-gnu-g++
export AR_X86_64_UNKNOWN_LINUX_GNU=x86_64-unknown-linux-gnu-ar
export CARGO_TARGET_X86_64_UNKNOWN_LINUX_GNU_LINKER=x86_64-unknown-linux-gnu-gcc

From the root of the project

rustup target add x86_64-unknown-linux-gnu
cargo build --release --target x86_64-unknown-linux-gnu --package golem-shard-manager

ARM MAC

Typically, the following should allow you to run it successfully.

brew tap messense/macos-cross-toolchains
brew install aarch64-unknown-linux-gnu
# If openssl is not in system
# brew install openssl
export OPENSSL_DIR=$(brew --prefix openssl)
