Overview ¶

Package execguard ties the processes lerd starts in a container to the run that started them. podman exec leaves them running when its caller dies or gives up, so a test run cut short keeps its browser busy for good.

const MarkerEnv = "LERD_EXEC"

MarkerEnv is set on every guarded exec; children inherit it, so it finds the whole tree, Chromium processes that start their own group included.

Functions ¶

func Kill ¶

func Kill(container string, markers ...string)

Kill ends every process in container that carries one of markers.

func Run ¶

func Run(ctx context.Context, cmd *exec.Cmd, container string) error

Run runs cmd, a podman exec into container, under a marker of its own, killed when ctx ends or lerd is interrupted and left to Sweep otherwise. Any other cmd runs on this machine in a process group of its own, see runHost.

func Sweep ¶

func Sweep()

Sweep kills what finished runs, and runs whose lerd no longer exists, left in their containers, one exec per container, and drops their records. A container that is gone took its processes with it.
