v1.1.0

1.1.0

First-class third-party / imperative integration.

• Imperative install: DartServiceManager.installDescriptor(descriptor, {startNow, force}) installs an already-built executable as a service —
  bypassing package resolution, manifest loading and compilation — with
  caller-supplied arguments, environment and runtime policy.
• ServiceDescriptor.forCurrentExecutable(...): install the currently
  running program (Platform.resolvedExecutable) as a service, handling the
  JIT (dart <script>) vs AOT-binary distinction.
• Runtime policy on ServiceDescriptor/ServiceInstallConfig and the
  dart_services: manifest: workingDirectory, restart
  (always/on-failure/never, new RestartPolicy enum), restartDelay,
  autoStart, stopTimeout, environmentFile. All default to the previous
  behaviour, so existing units/plists render unchanged.
• Manifest executable: as an alternative to script: — install a
  pre-built binary without compiling.
• Environment-file support (systemd EnvironmentFile=); drivers expose
  supportsEnvironmentFile and reject it where unsupported (launchd, Windows).
• render() / --dry-run: drivers can render the native definition
  (systemd unit, launchd plist, sc command) without touching the system;
  DartServiceManager.renderDefinition(...) and install --executable --dry-run expose it.
• reconfigure(descriptor): re-apply a changed descriptor, preserving the
  running state.
• The registry now persists the full descriptor (args/env/description/policy),
  so lifecycle, listing and reconfigure work without a manifest. Registries
  written by 1.0.x still load.
• CLI: install --executable <path>, --start-now, --dry-run,
  --restart, --restart-delay, --working-dir, --env-file,
  --no-auto-start, --force.
• Windows services now configure SCM failure/restart actions to match the
  restart policy.

Potentially breaking: two new sealed exception subclasses —
PermissionDeniedException and ServiceAlreadyInstalledException — are added
to ServiceManagerException. Code that does an exhaustive switch over the
exception hierarchy must handle the new cases.

1.0.1

• Add a Shelf HTTP server example (example/shelf_server) showing a real web
  server declared as a service and managed end-to-end, with graceful
  SIGTERM/SIGINT shutdown.
• Document package-wide operations in the README: a bare package reference
  (no :service) targets every service of the package — including
  uninstall — and uninstalling deletes each service's cached native binary.
