feat(provider): persist per-view view-state identity and durable viewStates#1546easonLiangWorldedtech wants to merge 13 commits into
Conversation
📝 SummarySummary by CodeRabbit
WalkthroughThe change adds durable non-secret state for each webview instance, excludes that state from settings transfer, and separates sidebar and editor-tab command routing. It also adds tab-specific commands and lifecycle tests for provider lookup, persistence, reuse, concurrency, and disposal. ChangesPer-view state and tab command routing
Estimated code review effort: 4 (Complex) | ~60 minutes Merge Risk: 🟡 Moderate · up to The change can restore selections to the wrong tab or fail to apply them, leave task and view modes inconsistent after a timeout, and allow deleted profiles to reappear. These behaviors should be corrected before merging. Sequence Diagram(s)Per-view state restorationsequenceDiagram

In `@src/activate/registerCommands.ts`:
- Line 288: Serialize concurrent tab creation in the openClineInNewTab flow by
storing a shared in-flight creation promise before awaiting
ContextProxy.getInstance(context), making subsequent callers await it instead of
creating another panel; clear the shared promise in finally after completion.
Add a regression test that starts openInNewTab and popoutButtonClicked before
the first creation resolves and verifies only one panel/provider is created.
In `@src/core/webview/ClineProvider.ts`:
- Line 737: Update loadViewState so mutations made to viewLocalState while
loading are tracked by field and reapplied after assigning loadedState,
preserving only dirty local fields such as apiConfiguration. Keep stable
persisted values authoritative for untouched fields and avoid merging the entire
pre-load buffer, which could allow temporary-id state to override stable
persisted state.

getValues() does not return stale profile data. Update
activateProviderProfileUnlocked, upsertProviderProfile, and
deleteProviderProfile to use ClineProvider#setValue/setValues for affected
fields, or invalidate those fields after mutation; preserve consistency between
getValues() and getState().
- Around line 3510-3512: Update ClineProvider.setValues to reject any present
mode value that is neither undefined nor a string before calling
ContextProxy.setValues or persisting state. Preserve the existing custom-mode
validation for string values and ensure invalid values such as numeric mode
values do not reach globalState or viewLocalState.
- Around line 751-764: Extend the loadViewState tests around the pending
getProfile flow to cover independent mutations of mode, currentApiConfigName,
and apiConfiguration, verifying each mutated value is reapplied after loading.
Add a no-mutation case that confirms persisted values remain authoritative, and
ensure the assertions distinguish each state field’s behavior.
In `@src/package.json`:
- Around line 290-307: Move the commandPalette contribution containing
zoo-code.plusButtonClickedInTab, settingsButtonClickedInTab,
marketplaceButtonClickedInTab, and historyButtonClickedInTab under
contributes.menus, preserving each command and its activeWebviewPanelId
condition so VS Code applies the visibility filters.

Replace the weak toBeDefined() assertion in the dispose spec with an identity check against the panel returned during creation, per the CodeRabbit actionable comment on this PR (review run 7c4cfeb3-6dd9-4615- 9a58-70cfc705eca2). The tracked tab is now pinned with toBe(panel) before the dispose assertions, so a wrong or duplicated tracked panel fails the suite instead of passing a defined-only check. Upstream: Zoo-Code-Org#1528 (vps2 F0)

Retain the tracked tab panel in the InTab handler cases and assert that getInstanceForView was called with that exact panel, per the CodeRabbit actionable comment on this PR (review run 4afe1273-8739-4235-90d3-311db5f6ccb9, inline comment 3952466254 on the tabHandlerCases spec). A handler resolving any other view now fails instead of passing on the stubbed provider result alone; the same identity pin is applied to plusButtonClickedInTab. Upstream: Zoo-Code-Org#1528 (vps2 F0)
…States Each ClineProvider instance now owns a unique viewId (renderContext plus a monotonic counter) and registers a stable viewStateId for durable persistence. - Per-view state buffer (viewLocalState) holds mode / currentApiConfigName / apiConfiguration overrides in memory; saveViewState persists the non-secret subset durably under the active view id, rekeyed to the stable id on registration. - viewStates is stored as a map pruned to the newest 50 entries; writes go through a serialized queue so concurrent provider instances merge without lost updates. - setViewStateId sanitizes ids and rejects "__proto__" so a per-view entry can never be keyed through the Object.prototype setter. - postMessageToWebview no longer awaits the webview ack: a remounted or disposed page never acknowledges, and awaiting would wedge task-critical callers. - History restore falls back to the default mode view-locally instead of writing the shared global mode. - GlobalState gains the "viewStates" key and GLOBAL_STATE_KEYS tracks it. Adds F1a coverage in ClineProvider.spec.ts (viewId uniqueness, saveViewState persistence semantics, loadViewState fallback and failure, pruning, the __proto__ guard) and adapts the two history-restore tests in ClineProvider.sticky-mode.spec.ts to the view-local restore. getState() merging of hydrated per-view values and the remaining view-state suites land in the follow-up (F1b).

Persist mode switches through per-view state
When handleModeSwitchUnlocked writes mode through updateGlobalState, it does not update viewLocalState or the durable viewStates entry. Because getValues() spreads viewLocalState over the global values, a view with a loaded mode pin reports the old mode and restores it after reload.
🐛 Proposed fix at Line 2078

These two focusInput assertions cannot distinguish the tab panel from the sidebar view.
Line 411 uses toHaveBeenCalledWith(tabPanel), and tabPanel is {} as vscode.WebviewPanel. toHaveBeenCalledWith compares by deep equality, and the sidebar fixture on line 404 is also an empty object. A handler that passed the sidebar view to getInstanceForView still satisfies this assertion.
The test on lines 397-399 has the matching gap: it asserts only that the sidebar provider received nothing. Removing the if (tabProvider) guard in registerCommands.ts (Line 243) keeps this test green, which is the surviving ConditionalExpression mutant the mutation gate reports.

📐 Maintainability & Code Quality | 🔵 Trivial | 💤 Low value
The stalled getProfile double only lets the last call be resolved.
Each invocation reassigns resolveProfile to the newest promise's resolver. A test that causes two overlapping loadViewState calls can therefore resolve only the second lookup; the first await never settles and the test hangs until the suite timeout instead of failing with a clear message. The current tests gate on toHaveBeenCalledTimes(1), so this is latent.
Keep a queue of resolvers, or fail fast when getProfile is called more than once.

An aborted switch now leaves the task and the provider on different modes.
Lines 2074-2079 already persist newMode into the task history item and set (task as any)._taskMode = newMode. The new gate returns before setValue("mode", ...), before ModeChanged, and before postStateToWebview(). When the mutation times out (the 30s PENDING_OPERATION_TIMEOUT_MS abort in enqueueProviderProfileMutation), the task is pinned to newMode while the provider, the view-local buffer, the durable viewStates entry, and the webview all keep the previous mode.
Check the signal before the task-level writes as well, or roll the task history item and _taskMode back when the switch aborts.

newMode: Mode,

Delete the profile from ProviderSettingsManager
deleteProviderProfile only removes the entry from listApiConfigMeta. It never calls providerSettingsManager.deleteConfig(profileToDelete.name). Because listConfig() reads the persisted apiConfigs, later refreshes can restore the deleted profile. Delete the profile from ProviderSettingsManager in this path before updating the metadata.

Bracket access to another instance's private members is fragile.
instance["viewLocalState"] and instance["_saveViewLocalStateFromMutation"] reach into private members of a sibling ClineProvider. TypeScript allows the index form, so this compiles, but a rename of either member breaks these two call sites silently at runtime and not at compile time.
Add a small internal accessor pair (for example a pinnedProfileName getter and an internal applyViewLocalMutation method) and call those instead.

access to sibling ClineProvider private members in the affected-instance

What
At the base commit
ClineProviderhas no per-view state identity: every view shares the same global mode / profile / apiConfiguration keys, nothing is persisted per view,postMessageToWebviewawaits an ack a remounted page never sends, and reset / history-restore writes leak across views. This PR lands the durable per-view core (fix unit F1a, 1/3): per-view identity, theviewStatespersistence pipeline, and the view-local state buffer. ThegetState()merging of hydrated per-view values and the webview-side identity / launch wiring land in the follow-ups (F1b / F1c).Design decisions
viewId= renderContext plus a monotonic counter (unique per instance for its lifetime).viewStateIdis the stable durable key (registered by the webview launch flow in F1c);rekeyPersistedViewStateEntrymoves the temporary-id entry to the stable id, stable id winning on a collision.savePersistedViewState) so concurrent provider instances merge without lost updates;viewStatesis pruned to the newest 50 entries (missingupdatedAtsorts oldest).setViewStateIdsanitizes ids and rejects__proto__: a per-view entry must never be keyable through theObject.prototypesetter. The fresh-read guard treats a corrupted non-object storage value as an empty map.viewLocalState):mode/currentApiConfigName/apiConfiguration(non-secret subset) live per view in memory.saveViewStateawaits the durable write before logging success.loadViewStatehydrates at registration, keeps the profile name and logs when the profile lookup fails, and discards a stale load when theviewStateIdchanges mid-lookup.setValues/setValuevalidatemodeagainstgetModeBySlug(unknown → log and ignore; non-string passes through) and keep or clear the matching buffer fields;undefined/nullvalues delete the buffer field rather than storing it.getValuesmerges context values with the buffer (buffer wins).postMessageToWebviewno longer awaits the webview ack (a remounted or disposed page never acknowledges; awaiting would wedge task-critical callers).resetStateclearsviewLocalStateand the view's persisted entry (after thecustomModesManager.resetCustomModesmodal confirm).saveViewState("mode", ...)instead of the shared global mode.Measurements

All F1a content is re-implemented against the base by hand-porting hunks from CS
