Build

Build go judge

Build by your own docker build -t go-judge -f Dockerfile.exec .

For cgroup v1, the go-judge need root privilege to create cgroup. Either creates sub-directory /sys/fs/cgroup/cpuacct/go_judge, /sys/fs/cgroup/memory/go_judge, /sys/fs/cgroup/pids/go_judge and make execution user readable or use sudo to run it.

For cgroup v2, systemd dbus will be used to create a transient scope for cgroup integration.

Build Shared object

Build container init cinit:

go build -o cinit ./cmd/go-judge-init

Build go_judge.so:

go build -buildmode=c-shared -o go_judge.so ./cmd/go-judge-ffi/

For example, in JavaScript, run with ffi-napi (seems node 14 is not supported yet):
