Lazily creates AutoUpdater only on macOS and Windows, preventing Linux and Android from subscribing to an unsupported native event channel.

Summary by CodeRabbit

  • Bug Fixes
    • Improved updater startup behavior by deferring desktop update initialization until needed.
    • Prevented unnecessary desktop event-channel activity during updater creation.
    • Preserved reliable desktop update checks and background scheduling.
    • Improved configuration URL connection reliability, including server selection and navigation recovery.
    • Prevented potential cleanup issues when leaving the connection-sharing screen.

📝 Walkthrough

Walkthrough

Updater now initializes AutoUpdater lazily. Linux config URL smoke tests are opt-in, and their harness uses router-based recovery and interactable controls. Globe-controller disposal is delegated to RotatingGlobe.

Changes

Desktop updater initialization

Layer / File(s) Summary
Lazy initialization and construction validation
lib/core/updater/updater.dart, test/core/updater/updater_test.dart
Updater retains an optional AutoUpdater and creates it only when desktop update operations access it. The test verifies that construction makes zero event-channel calls.

Linux config URL smoke testing

Layer / File(s) Summary
Workflow gating and smoke navigation recovery
.github/workflows/build-linux.yml, integration_test/vpn/config_url_connect_smoke_harness.dart
The workflow adds an opt-in config URL smoke-test step. The harness uses appRouter, hit-testable controls, and router fallbacks for navigation recovery and server selection.

Globe controller lifecycle

Layer / File(s) Summary
Delegated globe disposal
lib/features/share_my_connection/share_my_connection.dart
_GlobeViewState.dispose no longer directly disposes _globeController; RotatingGlobe manages its disposal.

Pull request overview

This PR prevents unsupported platforms (Linux and Android) from eagerly creating the AutoUpdater singleton, which otherwise opens a native event channel during construction. It does this by deferring AutoUpdater.instance creation until desktop-specific initialization paths are executed, and adds a regression test to ensure constructing Updater remains side-effect free with respect to desktop channels.

Changes:

  • Lazily instantiate the desktop AutoUpdater via a getter, avoiding native channel subscription at Updater() construction time.
  • Route desktop update operations through the lazily created AutoUpdater instance only on macOS/Windows code paths.
  • Add a unit test asserting that constructing Updater does not trigger calls on the desktop updater event channel.

File Description
lib/core/updater/updater.dart Makes AutoUpdater initialization lazy and only realized from desktop-only paths.
test/core/updater/updater_test.dart Adds a regression test ensuring Updater() construction does not initialize desktop method/event channels.

In @.github/workflows/build-linux.yml:
- Around line 279-288: Bound the optional Linux config URL smoke step by adding
a step-level timeout-minutes setting to the workflow step that runs
linux_config_url_smoke.sh, ensuring hung flutter tests cannot hold the job
indefinitely.

In `@integration_test/vpn/config_url_connect_smoke_harness.dart`:
- Around line 178-180: After appRouter.popUntilRoot() in the recovery flow,
replace the single delayed pump and one-time homeControl check with a bounded
polling loop that pumps and rechecks homeControl.hitTestable() until it succeeds
or the timeout is reached. Preserve the existing failure behavior after the
bound expires, and align the settling approach with the shared app_robot
recovery flow.
