[PERF] resolveWebviewView triggers redundant getState() calls (x3)

[0xMink]

Summary

resolveWebviewView() in src/core/webview/ClineProvider.ts calls this.getState().then(...) three times to read terminal and TTS settings. Each call runs the full getState() path (including CloudService/ContextProxy reads), creating redundant work during view activation.

Grep: resolveWebviewView + this.getState().then

Impact: Eliminates ~2 redundant async getState() executions during view activation, reducing duplicate reads and ensuring a single consistent settings snapshot. Three separate calls can theoretically return different values if settings change mid-resolution, making this both a performance and a correctness concern.

Affected location

Search pattern: this.getState().then in resolveWebviewView

• Terminal settings fetch (~line 756)
• TTS enabled fetch (~line 778)
• TTS speed fetch (~line 782)

Suggested fix

Consolidate into a single await this.getState() with destructuring. resolveWebviewView is already async, so this is consistent with the rest of the method.

Note: Preserve existing error-handling behavior when consolidating.

const {
    terminalShellIntegrationTimeout = Terminal.defaultShellIntegrationTimeout,
    terminalShellIntegrationDisabled = false,
    terminalCommandDelay = 0,
    terminalZshClearEolMark = true,
    terminalZshOhMy = false,
    terminalZshP10k = false,
    terminalPowershellCounter = false,
    terminalZdotdir = false,
    ttsEnabled,
    ttsSpeed,
} = await this.getState()

Terminal.setShellIntegrationTimeout(terminalShellIntegrationTimeout)
Terminal.setShellIntegrationDisabled(terminalShellIntegrationDisabled)
Terminal.setCommandDelay(terminalCommandDelay)
Terminal.setTerminalZshClearEolMark(terminalZshClearEolMark)
Terminal.setTerminalZshOhMy(terminalZshOhMy)
Terminal.setTerminalZshP10k(terminalZshP10k)
Terminal.setPowershellCounter(terminalPowershellCounter)
Terminal.setTerminalZdotdir(terminalZdotdir)
setTtsEnabled(ttsEnabled ?? false)
setTtsSpeed(ttsSpeed ?? 1)

Acceptance criteria

• getState() is called once instead of three times during view resolution
• Terminal and TTS settings are still applied correctly
• No behavioral change (including error handling)

---

Problem: resolveWebviewView() triggers three redundant getState() calls during view resolution.

Context: Any user opening the Roo Code panel; duplicates cloud/context reads and can apply inconsistent settings if state changes mid-resolution.

Reproduction steps:

1. Open the Roo Code panel (or reload VS Code)
2. Add temporary logging/breakpoints around getState() to observe three invocations in resolveWebviewView

Expected result: One getState() execution; single snapshot applied.

Actual result: Three independent getState() executions.

App Version: v3.47.3

API Provider / Model Used: N/A (not provider-dependent)

Roadmap alignment: Enhanced User Experience (faster activation)

I've analyzed this issue and here's my proposed implementation plan:

1. In src/core/webview/ClineProvider.ts, replace the three separate this.getState().then(...) calls (lines ~750-778) with a single await this.getState() using destructuring.
2. The consolidated block will destructure all terminal settings (terminalShellIntegrationTimeout, terminalShellIntegrationDisabled, terminalCommandDelay, terminalZshClearEolMark, terminalZshOhMy, terminalZshP10k, terminalPowershellCounter, terminalZdotdir) and TTS settings (ttsEnabled, ttsSpeed) from one call.
3. Default values will be preserved exactly as they are today (e.g., terminalShellIntegrationTimeout = Terminal.defaultShellIntegrationTimeout, ttsEnabled ?? false, ttsSpeed ?? 1).
4. Since the existing .then() calls have no .catch() handlers, there is no error-handling behavior to preserve -- the consolidated await will behave identically (unhandled rejection propagation).
5. No test changes needed since existing tests mock getState() and will work the same with fewer calls.

The result: one getState() call instead of three, giving a single consistent settings snapshot with no behavioral change.

Please mention @roomote in a comment saying that you approve this plan, and I'll proceed with the implementation.

Thanks @roomote. I implemented this in PR #11320 (single await this.getState() + destructuring; same defaults, no behavioral change). It closes #11319. Review on the PR is appreciated.

[roomote]

I've seen your comment and PR #11320. I'll also explore a potential fix independently and open a draft PR to share progress. Review and feedback on both approaches are welcome.

[roomote]

Opened PR #11321 with my attempt at addressing this (same approach -- single await this.getState() + destructuring, no behavioral change). Feedback welcome!
