WindowsJobBackend class final

The Windows backend: Job Object descriptor generation (execution needs FFI — Phase 4 follow-up).

Implemented types

• CubeSandboxBackend

Constructors

WindowsJobBackend()

Creates the Windows backend.

const

Properties

enforces → bool

Whether this backend actually confines at the OS level. false means wrapCommand is a passthrough and kernel mode degrades to the Dart policy layers.

no setter, override

hashCode → int

The hash code for this object.

no setter, inherited

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

Methods

describe() → String

override

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

toString() → String

A string representation of this object.

inherited

wrapCommand(String command, {required String profilePath, Map<String, String> env = const {}}) → String

Wraps command so it runs inside the OS sandbox. profilePath names the profile file staged for the current spec (.fah/cube-profiles/); implementations that confine by other means may ignore it. env carries the caller's per-exec environment (ShellExecOptions.env): kernel wrapping must thread it into the clean child environment or session vars and secrets are silently dropped — entries override the backend's cube-bound vars. Implementations that change nothing may ignore it too.

override

Operators

operator ==(Object other) → bool

The equality operator.

inherited

Static Methods

buildJobDescriptor(CubeResourceLimits limits) → Map<String, Object?>

Computes the Job Object limit descriptor for limits:

Constants

cpuRateFlag → const int

JOB_OBJECT_LIMIT_CPU_RATE — a CPU rate control.

killOnJobCloseFlag → const int

JOB_OBJECT_LIMIT_KILL_ON_JOB_CLOSE — stray children die with the job.

processMemoryFlag → const int

JOB_OBJECT_LIMIT_PROCESS_MEMORY — a per-process memory cap.
