Module runtime_call

Expand description

Running a runtime for a call: its output, its process group and the cleanup after a failure.

Structs§

Runtime 🔒: A runtime whose process group gets killed if it is dropped before it got reaped, like a call in progress which the shutdown drops once it stops waiting for it. kill_on_drop only kills the runtime, its helpers in its group, like hooks or a runc init which did not set up the container yet, would be left running, see ChildReaper::stop_runtime. Until it got reaped, the ID of the group is still the one of the runtime.
RuntimeCall 🔒: How ChildReaper::create_child runs a runtime.
RuntimeDeadline 🔒: When the runtime of a call gets killed, and how long it got for the error of one which took longer.
RuntimeFailure 🔒: A runtime call which failed before its runtime exited, see ChildReaper::stop_runtime.
RuntimeOutput 🔒: The stdout and stderr of a runtime with pipes of its own, read in the background until they end. Only the end of stderr is kept, it holds the error, stdout is not of interest.
StartedChild 🔒: The process a runtime started, see ChildReaper::create_child.

wait_unless_stopped 🔒: Wait for future for at most limit, and only for stopped more once the shutdown stopped the call through stop, see ChildReaper::STOP_BUDGET. None if it did not finish by then.
