test(webview): add parallelMode spec with viewStates pruning edges and dispose retention by easonLiangWorldedtech · Pull Request #1555 · Zoo-Code-Org/Zoo-Code

easonLiangWorldedtech · 2026-09-06T22:07:18Z

Draft PR — vps2 unit F2 (durable per-view state regression coverage).

Supersedes PR #1554 (closed). The first cut of this branch was built on the
wrong stack base and extended the existing spec file instead of adding the
mandated ClineProvider.parallelMode.spec.ts. PR #1554 was closed because this
mock-GitHub environment offers no draft-conversion API (no gh pr update
subcommand, no draft flag on gh pr edit, and the REST PATCH /pulls /
GraphQL updatePullRequest inputs both ignore or reject draft) — so the only
path for a wrongly-opened PR is close + re-create with --draft. This is that
re-created draft.

Tracking: easonLiangWorldedtech#41 (vps2 series ledger). Upstream issue:
#1553.

Scope

New file only: src/core/webview/__tests__/ClineProvider.parallelMode.spec.ts
(733 lines), created on the F1c head 090d2c87e:

L1–675: the vps2 CS parallelMode spec preamble copied 100% verbatim
(line-by-line verified, 0 mismatches): imports, the vi.mock blocks (modes
with defaultModeSlug: "code", cloud, modelCache, zoo-code-auth,
RateLimitClock, …), the beforeAll/afterAll console spies, the
describe("ClineProvider - Parallel Mode Support") open, the
globalState-backed ExtensionContext fixture, and createMockWebviewView.
This preamble is a shared series asset: F3 and F4 append their describe
blocks into this file, so it lands in the series ahead of both. No mock/shape
adaptations were needed — it compiles and passes at the F1c head as-is.
The CS import list is kept intact (specifiers only consumed by F3/F4's future
describes are kept on purpose; the repo eslint config has
@typescript-eslint/no-unused-vars off, so the verbatim list passes).
3 F2 regression tests:
1. should drop the entry without updatedAt first when the cap is exceeded
  — a legacy entry without updatedAt ranks ?? 0 and falls off the
  50-entry cap before every timestamped entry.
2. should keep the earliest inserted entries when updatedAt values tie
  — equal updatedAt preserves insertion order (stable sort); the first 50
  registered views survive.
3. should preserve persisted viewStates entry when an editor provider is disposed during teardown (Preserve durable editor view state across provider disposal #1065) — a disposed editor provider's
  viewStates entry survives teardown.

Standalone diff vs stack base 090d2c87e (F1c head): 1 file changed,
733 insertions(+), 0 deletions(-) — a+d 733. The existing
ClineProvider.spec.ts is byte-identical to the F1c head.

Budget

a+d 733 vs the 400-soft / 1000-hard budget: soft exceeded by composition,
exactly as F1a's 999 — ~675 of the 733 lines are the verbatim CS preamble,
shared series infrastructure (F3/F4 append into this file; if F3 had carried
the preamble, F3 would have breached the 1000 hard cap). Under the hard cap.
Stryker-diff gate: vacuous — the commit changes 0 executable lines
(test-only); 0 executable changed lines, 0 raw mutants.
vitest: 3/3 pass in the new file (coordinator re-ran independently).
check-types, eslint (--prune-suppressions, 0 as any in the new file,
suppression counts unchanged — the prune pass's re-indent was reverted),
prettier (--end-of-line=auto): all green.

Post-merge interaction flag

Upstream main has since advanced to 4c7474d42 (v3.82.0+), where
ClineProvider.dispose() was rewritten to drain registry tasks. The #1065
dispose-retention test is green at this base of record; re-verify after the
lower units merge. This series keeps the base of record
(0d937c050) and rebases after lower PRs merge.

Series mechanics

Base of record: upstream/main @ 0d937c050; PR base is main; the branch is
stacked on the F1c head 090d2c87e.
Draft PR per unit; merge order F1a → F1b → F1c → F2 → F3 → F4 → F5 → F6 → F7.
The CS parallelMode spec describes for the F1-series (L676–1363) are already
shipped by F1a/F1b/F1c; the F3/F4 describes (L1364–1791) are pending units
that append to this file.

📝 Summary

Summary by CodeRabbit

New Features
- Added durable, per-view state for parallel webview tabs, preserving mode and API configuration independently across sessions.
- Added dedicated title-bar controls for popped-out tabs, including add, settings, marketplace, and history actions.
- Opening an existing tab now reveals and reuses it instead of creating a duplicate.
- Added improved recovery when browser storage is unavailable.
Bug Fixes
- Corrected title-bar actions so they target the appropriate sidebar or tab instance.
- Prevented view-specific settings from overwriting shared settings.

Walkthrough

Adds durable per-view state for parallel webviews, stable webview identifiers, view-specific API configuration recovery, non-blocking webview messaging, and separate sidebar and tab command routing.

Changes

Per-view state and surface routing

Layer / File(s)	Summary
View identity and state contracts `packages/types/src/...`, `webview-ui/src/context/...`, `webview-ui/src/utils/...`	Adds persisted view-state schemas, `viewStateId` messaging, stable webview identifiers, browser-storage fallbacks, and tab-specific command IDs.
Provider-local state persistence `src/core/webview/ClineProvider.ts`, `src/core/webview/__tests__/ClineProvider*`, `src/eslint-suppressions.json`	Adds per-view buffers, durable persistence, pruning, re-keying, state merging, reset cleanup, provider ownership lookup, and related tests.
Launch-time view recovery `src/core/webview/webviewMessageHandler.ts`, `src/core/webview/__tests__/webviewMessageHandler.spec.ts`	Stores the view identifier, validates view-local API configuration, repairs invalid selections, and routes settings updates through the provider.
Sidebar and tab command routing `src/activate/registerCommands.ts`, `src/activate/__tests__/registerCommands.spec.ts`, `src/package.json`	Tracks sidebar and tab panels independently, targets commands to the associated provider, reuses tracked tabs, and registers tab title-bar commands.

Estimated code review effort: 5 (Critical) | ~90 minutes

Merge Risk: 🟠 High · up to dbd7e

Tab commands and per-view mode or profile selection can become stale or stop working during ordinary launch, switching, and disposal flows. These regressions should be fixed before merge.

Full details: Regression Evidence

Explanation

The aggregate PR changes webviewMessageHandler to route every updateSettings mutation through provider.setValue at src/core/webview/webviewMessageHandler.ts:880-882. This route updates view-local state and durable per-view pins. The handler tests add a delegating setValue mock, but they never assert that mockClineProvider.setValue was called. Their assertions only inspect contextProxy.setValue, so the old direct provider.contextProxy.setValue(...) implementation would still satisfy the tests. The changed routing behavior therefore lacks focused handler-level coverage.

Resolution

Add a focused webviewMessageHandler updateSettings test for a view-local setting such as mode or currentApiConfigName. Assert mockClineProvider.setValue receives the normalized key and value. Keep the mock implementation able to record the call, and optionally assert that the handler does not call contextProxy.setValue directly. This test must fail if the handler regresses to the old direct ContextProxy write.

…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).

…overrides Fold ClineProvider viewLocalState on top of ContextProxy values in getState() (mode, apiConfiguration, and all per-view fields) so each webview reports its own selections while falling back to shared global state for everything else. Ports the getState-merging and local-state-isolation spec coverage from the superseded vps2 source. Also pins the full default surface of the merged read path, including the apiConfiguration provider fill-in when provider settings sanitize the raw value away (mutation-diff gate).

…tore deleteProviderProfile only rewrote the UI-facing listApiConfigMeta and currentApiConfigName in ContextProxy, leaving the profile's settings in the ProviderSettingsManager store (context.secrets). Per-mode mappings (modeApiConfigs) that still pointed at the deleted profile re-activated its stale settings on the next handleModeSwitch, clobbering the active configuration: the subtask child profile's gpt-4.1-mini leaked into ask-mode tasks, breaking downstream e2e suites (60s timeouts on search_files no-match and terminal reuse after zero-chunk shell race). Purge the profile from the store on delete so dangling mode mappings can no longer resolve it: listConfig().find(id) fails and handleModeSwitch continues with the current configuration. The F3 mode/profile isolation commit further up the chain introduces the same purge plus per-view pin handling. Regression test: sticky-profile spec "deleteProviderProfile removes the stored profile so a dangling mode mapping can no longer re-activate it".

… state WMH webviewDidLaunch persists the webview view-state id via provider.setViewStateId and re-pins the view-local currentApiConfigName through provider.saveViewState when the view-local profile is missing but the shared global selection is still valid. updateSettings is routed through provider.setValue so view-local buffer and pin sync stay consistent with the other mutation paths. The webview VSCodeAPIWrapper gains a stable getViewStateId persisted via setState (with an in-memory fallback) and the launch effect posts the id with the webviewDidLaunch message.

Inline comments:
In `@src/activate/__tests__/registerCommands.spec.ts`:
- Around line 287-294: Update the disposed-tab test for the in-tab handlers to
retain the panel passed to setPanel, assert ClineProvider.getInstanceForView is
called with that same panel, and preserve the existing no-op message assertions.

In `@src/activate/registerCommands.ts`:
- Around line 288-295: Update the stale-panel disposal handling in the tab-panel
registration flow so its onDidDispose callback clears the tracked tab reference
only if the disposing panel is still the currently tracked panel; preserve the
replacement panel reference otherwise. Add a regression test covering
getInstanceForView returning undefined, replacement creation, stale-panel
disposal, and continued tab command functionality.

In `@src/core/webview/__tests__/ClineProvider.parallelMode.spec.ts`:
- Around line 695-696: Update the assertions for the entries returned by
prunePersistedViewStates to compare the complete expected PersistedViewState
objects, rather than only checking that view-0 and view-49 are defined. Ensure
the exact persisted fields, including mode and any other selected-entry data,
are verified for both surviving entries.

In `@src/core/webview/ClineProvider.ts`:
- Around line 3186-3188: Update handleModeSwitchUnlocked to persist the new mode
through this.setValue("mode", newMode) instead of only updating contextProxy via
updateGlobalState, keeping viewLocalState.mode synchronized for getState() and
subsequent tasks.
- Around line 396-397: Update loadViewState and the same-view
saveViewState/setValues mutation paths in ClineProvider to track a mutation
version; capture the version before awaiting getProfile, and apply the loaded
snapshot only if the version is unchanged, preserving newer viewLocalState
mutations.

In `@src/core/webview/webviewMessageHandler.ts`:
- Around line 648-657: Update the condition around the global re-pin branch to
depend on globalStillValid and globalConfigName, removing the unnecessary name
guard so a valid shared selection is preserved when the first list entry is
nameless. Add a test covering a valid globalConfigName with a nameless first
entry, asserting updateGlobalState does not overwrite the existing selection.

In `@webview-ui/src/utils/vscode.ts`:
- Line 51: Update the persisted view-state ID handling around
existingViewStateId to apply the same trimming and rejection rules as
ClineProvider.setViewStateId, including whitespace-only and "__proto__" values;
return the normalized valid ID, otherwise generate and persist a new ID. Add
regression coverage for both invalid values.
