Summary of Changes

Hello @GaoFuhong, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request addresses an issue where changing edge routers during node movement could trigger unwanted events. By introducing a silent option for router modifications and explicitly requesting asynchronous view updates, the PR ensures a smoother and more efficient experience when moving selected nodes, preventing extraneous event emissions and optimizing rendering.

Highlights

  • Silent Router Operations: The setRouter and removeRouter methods are now called with the silent: true option during router fallback and restoration processes within the selection plugin. This prevents unnecessary events from being emitted when edge routers are temporarily changed or restored.
  • Asynchronous View Updates: An explicit asynchronous view update is now requested for edge views after their routers are restored. This ensures that the UI correctly reflects the original router configuration without blocking the main thread, improving performance and responsiveness.
  • New Test Cases: Two new test cases have been added to verify the correct behavior of silent router operations and asynchronous view updates during the selection plugin's router fallback and restoration logic.

Code Review

This pull request aims to fix an issue with router changes during selection dragging by making them silent to avoid firing events. The changes in src/plugin/selection/selection.ts correctly add the { silent: true } option when degrading and restoring routers, and also add a necessary asynchronous view update request.

However, I've found a bug in how edge.setRouter is called during router restoration. It doesn't handle the case where the original router is a string, leading to incorrect arguments being passed. I've provided a suggestion to fix this.

Additionally, one of the new tests in __tests__/plugin/selection.spec.ts has a logical flaw that could cause it to pass incorrectly. I've included a comment with a fix for the test logic.

Once these issues are addressed, the PR should be good to go.

The call to edge.setRouter is incorrect when original is a string. The setRouter method has multiple overloads. When the first argument is a string, the second argument is for router args, and the third is for options (like silent). When the first argument is an object, the second is for options. Since original can be a string, { silent: true } is incorrectly passed as router arguments instead of options. You should check the type of original to call setRouter correctly.

        if (typeof original === 'string') {
          edge.setRouter(original, undefined, { silent: true });
        } else {
          edge.setRouter(original, { silent: true });
        }

The logic to check if the router is restored silently is flawed. The || operator causes short-circuiting, and the check for (options as any)?.silent === true is not always executed when router is a string. This means the test could pass even if the silent option is missing.

Suggested change
const restoreSilent = spySetRouter.mock.calls.some(
([router, options]) =>
(typeof router === 'string' && router === 'manhattan') ||
(typeof router === 'object' &&
(router as any).name === 'manhattan' &&
(options as any)?.silent === true),
)
const restoreSilent = spySetRouter.mock.calls.some(
([router, options]) =>
((typeof router === 'string' && router === 'manhattan') ||
(typeof router === 'object' &&
(router as any).name === 'manhattan')) &&
(options as any)?.silent === true,
)
