Closes: #1502

Description

Adds an inline ModelSelector to the chat input toolbar so users can switch models directly from chat instead of opening Settings mid-workflow.

Key changes:

  • ModelSelector component (webview-ui/src/components/chat/ModelSelector.tsx):
    • Mounted in ChatTextArea alongside the existing ModeSelector and ApiConfigSelector.
    • Supports both dynamic-model providers (e.g. OpenRouter) via useRouterModels and static-model providers via getStaticModelsForProvider.
    • Filters models using the organization allow-list (filterModels) and hides deprecated models from selection (while keeping an active deprecated model visible).
    • Uses Fzf for search once the model list exceeds SEARCH_THRESHOLD (6).
    • Gracefully falls back with a tooltip (chat:selectModelUnsupported) and click-to-settings handler for unsupported providers.
  • Robust host-side model update:
    • Webview sends an updateProfileModel message containing { expectedProvider, patch }.
    • Host validates that the visible profile matches the target profile and that storedProvider === expectedProvider.
    • Filters patch to only allowed model IDs and reset side-effect keys (RESET_ONLY_KEYS).
    • Enforces authoritative organization allow-list validation before persisting.
    • Updates profile in providerSettingsManager, synchronizes context settings, and rebuilds current task LLM handler immediately without custom rollback side-effects.
  • Lifecycle & concurrency hardening:
    • Guards active and queued profile mutations upon provider disposal: rejects pending callbacks immediately without writing state.
    • Checks cancellation signal before upsertProviderProfile saves configuration.
    • Protects context-update rollback from overwriting newer profile updates saved concurrently by another provider instance.
    • Verifies active task identity remains unchanged throughout async save and context operations before rebuilding task API handler or persisting sticky profiles.
    • Added AbortSignal handling to fetchRouterModels in useRouterModels.ts to ensure event listeners and timeout timers are promptly cleaned up when components unmount or queries cancel.
  • i18n & Visual:
    • Added selectModel and selectModelUnsupported translation strings across all 18 supported locales.
    • Updated visual regression test tab indices and screenshots.

Test Procedure

  • Unit tests:
    • webview-ui/src/components/chat/__tests__/ModelSelector.spec.tsx: 47 tests covering supported/unsupported providers, dynamic/static model lists, search thresholds, allowlist filtering, and selection side-effects.
    • webview-ui/src/components/chat/__tests__/ChatTextArea.spec.tsx: 74 tests including model selector tooltip, disabled states, and message payload verification.
    • webview-ui/src/components/ui/hooks/__tests__/useRouterModels.spec.ts: 14 tests covering abort signal handling, timer cleanup, and listener removal.
    • src/core/webview/__tests__/webviewMessageHandler.updateProfileModel.spec.ts: 8 tests covering parameter validation and provider delegation.
    • src/core/webview/__tests__/ClineProvider.updateProfileModel.spec.ts: 23 tests covering profile patch merge, provider mismatch rejection, allowlist enforcement, task sticky profile coordination, concurrent multi-instance rollback protection, fake-timer timeout serialization, and disposal lifecycle cancellation.
  • Typecheck & Lint:
    • pnpm check-types passed across all 11 packages (0 errors).
    • pnpm lint passed across all 11 packages (0 warnings, 0 errors).

📝 Summary

Summary by CodeRabbit

  • New Features
    • Added a searchable model selector in chat for supported providers, with organization-based filtering and provider-specific options.
    • Selecting a model updates the active configuration while preserving unrelated settings. Selection is unavailable when no configuration is saved or the provider does not support it; a shortcut opens settings.
    • The selector includes loading and no-results states, and excludes deprecated models except the currently selected one.
    • Added translated model-selection, loading, and search-clearing labels across supported languages.
  • Bug Fixes
    • Improved reliability of model changes during concurrent updates, cancellation, or provider disposal, helping prevent stale changes from overwriting newer settings.

Walkthrough

This change adds model selection to the chat toolbar. The selector sends provider-qualified model patches through the webview message handler to ClineProvider, which validates and saves profile updates. It also adds router-model request cancellation, localized selector text, and tests.

Adds provider-aware model lists, filtering, search, selection states, and abortable router-model requests. Adds selector tests and localized labels for model selection, loading, and clearing search.
Chat toolbar and message dispatch
webview-ui/src/components/chat/ChatTextArea.tsx, webview-ui/src/components/chat/__tests__/ChatTextArea.spec.tsx, webview-ui/src/components/chat/__tests__/ChatTextArea.visual.tsx, packages/types/src/vscode-extension-host.ts, src/core/webview/webviewMessageHandler.ts, src/core/webview/__tests__/webviewMessageHandler.updateProfileModel.spec.ts
Adds ModelSelector to the chat toolbar and sends the current profile name, expected provider, and model patch. Adds the message type and validates incoming messages before dispatch.
Profile normalization and conditional updates
src/core/config/ProviderSettingsManager.ts, src/core/config/__tests__/ProviderSettingsManager.spec.ts
Centralizes profile normalization and adds conditional model updates and restoration. The manager checks profile identity and provider, validates patches, and rechecks concurrent storage changes.
Serialized provider-profile mutations
src/core/webview/ClineProvider.ts, src/core/webview/__tests__/ClineProvider.updateProfileModel.spec.ts
Adds serialized, cancellation-aware profile updates with organization allow-list checks, conditional rollback, and active-task safeguards. Tests cover validation, cancellation, ordering, and rollback.

Full details: Regression Evidence

Explanation

ProviderSettingsManager.saveConfig adds concrete concurrency behavior at src/core/config/ProviderSettingsManager.ts:416-438: it rereads storage, rebases the profile when rawLatest changes, performs storeWithCas, and falls back to a final regular write when the CAS check fails. The changed SaveConfig tests at src/core/config/__tests__/ProviderSettingsManager.spec.ts:415-710 cover normal saves, filtering, and storage errors, but none change the secret value between the reads or exercise the CAS-retry and fallback branches. The new competing-write tests cover restoreConfigIfMatches and updateProfileModel, not saveConfig. The ModelSelector, message handler, lifecycle, router cancellation, and chat-composer snapshot changes do have focused evidence.

Resolution

Add focused ProviderSettingsManager.saveConfig tests. Interleave a competing storage write between rawBefore and rawLatest and verify the saved profile is rebased onto the latest profiles without losing unrelated changes. Also force a change before storeWithCas and verify the final-read fallback writes the requested profile while preserving the latest unrelated fields. Assert the resulting stored profile and write calls.

Full details: Persistence Integrity

Explanation

ProviderSettingsManager.storeWithCas is not atomic. It performs secrets.get at lines 908-910 and a separate secrets.store at line 912. A second provider instance can write after the read and before the store. The model update or rollback can then overwrite that instance's API key, base URL, or model change while reporting success. The changed saveConfig path also falls back to an unconditional store at lines 432-438 after CAS failure, which can overwrite a later concurrent write. The per-instance _lock does not protect concurrent manager instances.

Resolution

Use a real storage-level compare-and-swap or a shared lock that covers the read-and-write operation for every ProviderSettingsManager instance. Do not use the unconditional store fallback after CAS failure. Retry from the latest value under the shared atomic mechanism, or return cas_failed without writing. Add a race test where a competing write occurs after the CAS read returns and before the store call.

Review comments at
@src/core/webview/__tests__/ClineProvider.updateProfileModel.spec.ts:
- Around line 438-451: Add a separate test alongside the existing authenticated
organization-policy test for `updateProfileModel`: keep `isAuthenticated()`
true, make `getOrganizationSettings()` return `undefined`, and verify the update
is rejected without saving and shows the organization allowlist error.

Review comments at @src/core/webview/ClineProvider.ts:
- Around line 2097-2109: Update the merge loop and matchesSavedSettings in the
profile-save flow to track keys that are actually applied after validation, then
compare only those keys against the saved profile. Preserve the existing
provider and model checks, and exclude skipped patch entries from the rollback
comparison.
- Around line 1961-1978: Update getOrganizationAllowListForProfileMutation to
return ORGANIZATION_ALLOW_ALL when an authenticated session has no organization
settings, matching the fallback behavior of getState() and avoiding an undefined
allow-list.

Review comments at
@webview-ui/src/components/ui/hooks/__tests__/useRouterModels.spec.ts:
- Around line 236-266: Update both no-abort-signal tests for fetchRouterModels
to capture the message listener registered through addEventListener and assert
removeEventListener receives that exact function reference instead of
expect.any(Function).

2022-2042: 🎯 Functional Correctness

No provider-key mismatch exists here.

PROVIDER_MODEL_CONFIG uses the same model fields as the provider definitions. Shared providers use apiModelId; provider-specific definitions use fields such as openRouterModelId, requestyModelId, and zooGatewayModelId. OpenAI uses openAiModelId, which the host also handles explicitly.

The model key is not dropped, so the claimed reset-without-model-change path does not occur. No rejection guard is needed.

🟡 Minor · Make the competing save occur after the first read… · ProviderSettingsManager.spec.ts:1678-1689

src/core/config/__tests__/ProviderSettingsManager.spec.ts:1678-1689
🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Make the competing save occur after the first read resolves.

The first secrets.get callback currently awaits managerB.saveConfig(...) before returning storedRaw. This updates storedRaw before managerA performs its initial comparison, so restoreConfigIfMatches returns false before reaching the write-time recheck. The test would still pass if that recheck were removed.

Return the original profile from the first read, then perform the competing save before the second read. This makes the test fail when the write-time recheck is absent.

1979-1979: An authenticated session without organization settings still rejects every chat model update.

This line returns undefined when getOrganizationSettings() returns nothing. updateProfileModel then shows violated_organization_allowlist and drops the update. getState() uses CloudService.getAllowList() for the same case, and that call falls back to ORGANIZATION_ALLOW_ALL. As a result, the two allow-list checks disagree for personal accounts. A previous review raised this concern. The new test confirms the fail-closed behavior is intentional. Confirm that blocking personal-account users from the chat model selector is the intended product behavior.

and hold it across the complete read, validation, revalidation, and write
sequence; do not rely on storeWithCas alone to provide atomicity.

- Line 1085: Update the listener cleanup test near `removeEventListenerSpy` to
also spy on `addEventListener`, capture the function registered for the
`"abort"` event, and assert that `removeEventListener` receives that exact
function reference instead of using `expect.any(Function)`.

Clone defaultProviderProfiles before the fallback mutation.

When rawFinal is empty, finalProfiles references this.defaultProviderProfiles. The following assignment mutates the shared defaults. A later load() clones those mutated defaults, so a reset or empty storage can inherit the fallback profile.

🐛 Suggested fix
 					const finalProfiles = rawFinal
 						? (JSON.parse(rawFinal) as ProviderProfiles)
-						: this.defaultProviderProfiles
+						: structuredClone(this.defaultProviderProfiles)

Clone this.defaultProviderProfiles in the empty-rawFinal fallback before
assigning to finalProfiles in the fallback branch of ProviderSettingsManager;
keep the parsed-storage path unchanged so the subsequent profile assignment

Serialize provider-profile mutations across manager instances.

ProviderSettingsManager keeps _lock per instance, but the sidebar and editor-tab providers create separate manager instances. storeWithCas performs secrets.get and secrets.store separately, and SecretStorage provides no atomic CAS. Both managers can pass the comparison and then write different snapshots, so the later write can silently lose the earlier profile update.

Use a mutex shared by all instances and keyed by secretsKey. Hold it across the complete read, validation, revalidation, and write for every in-host profile mutation. Documentation or commit-message changes alone do not prevent this race. The mutex provides extension-host serialization; it does not make SecretStorage atomic.

Suggested fix
-	private _lock = Promise.resolve()
+	private static readonly locks = new Map<string, Promise<void>>()
 	private lock<T>(cb: () => Promise<T>) {
-		const next = this._lock.then(cb)
-		this._lock = next.catch(() => {}) as Promise<void>
+		const key = this.secretsKey
+		const previous = ProviderSettingsManager.locks.get(key) ?? Promise.resolve()
+		const next = previous.then(cb)
+		ProviderSettingsManager.locks.set(key, next.then(() => undefined, () => undefined))
 		return next

Assert that the removed listener is the same function that was added.

expect.any(Function) also passes when the code removes a different function. If that happens, the real listener stays attached and leaks. Spy on addEventListener too. Capture the function passed for "abort", then assert that removeEventListener received that same function.

As per path instructions: "For listener registration and removal, assert the same function reference was added and removed (not expect.any(Function))."
