fix: infinite save issue and improve timer logic in ContentApp

[sijan2]

Improve Content Saving Mechanism

Overview

This pull request aims to enhance the content saving mechanism in the ContentApp component. The changes focus on improving the timer and save functionality to provide a more reliable and responsive user experience.

Changes

• Key Changes:

  • Refactored the timer logic to use a separate saveTimeoutRef to schedule the content save after the timer completes.
  • Implemented a scheduleSave function to manage the save timeout and ensure that the content is saved only once the timer has completed.
  • Added cleanup logic in the useEffect hook to stop the timer and clear the save timeout when the component is unmounted or the popover is closed.

• New Features:

  • None

• Refactoring:

  • Improved type safety by using a custom TimerId type for the timer references.
  • Simplified the timer start and stop logic by moving the stopTimer call to the beginning of the startTimer function.

Impact

The changes in this pull request aim to address potential issues with the content saving mechanism, such as:

1. Ensuring that the content is saved only once the timer has completed, rather than potentially saving multiple times if the timer is restarted.
2. Properly cleaning up the timer and save timeout when the component is unmounted or the popover is closed, to prevent potential memory leaks or unexpected behavior.
3. Improving the overall code quality and maintainability by using more type-safe references and simplifying the timer logic.

These improvements should result in a more reliable and responsive content saving experience for the users of the ContentApp component.

Code Review

❗ Attention Required: This PR has potential issues. 🚨

Potential Race Condition

The `scheduleSave` function might not clear the timeout if `saveContent` is called synchronously.

Potential Solution: Ensure that `clearTimeout` is always called before setting `saveTimeoutRef.current` to `null`.

apps/extension/content/ContentApp.tsx | 143 - 150

reason_for_request: If `saveContent` completes synchronously, `saveTimeoutRef.current` will be set to `null` before `clearTimeout` is called, potentially leading to race conditions or unexpected behavior.

level: [critical] , severity: [10]

Timer Cleanup

The removal of `clearInterval(timerRef.current!)` in the removed lines could lead to a resource leak if the timer is not cleared properly.

Potential Solution: Ensure that `clearInterval` is called when the timer is no longer needed, such as within the `stopTimer` function.

apps/extension/content/ContentApp.tsx | 116 - 118

reason_for_request: Failing to clear intervals can lead to performance issues and unexpected behavior.
