[Fix] Mode profile choices leak between VS Code windows by PierrunoYT · Pull Request #2110 · Zoo-Code-Org/Zoo-Code

PierrunoYT · 2026-10-20T19:41:44Z

Problem

The mode -> provider profile map is stored in shared extension storage, so every VS Code window reads and writes the same one. Selecting a profile in window 2 overwrote the entry window 1 relied on, and a subtask started from window 1 in a different mode (also mode switches and history restore) picked up window 2's model config.

Fix

ClineProvider keeps an in-memory map of the profiles chosen in its own window and checks it before the shared map. All mode-profile lookups and writes go through two helpers (getModeConfigId / setModeConfig); the shared write is unchanged.

Limitations

The per-window map is not persisted across window reloads.
Each window snapshots the shared mode map when it opens. Modes absent from that snapshot keep the window's current profile. Cached IDs whose profile was removed (e.g. by a reset) fall back to the shared map.

Tests

Added a regression test in ClineProvider.spec.ts. ClineProvider suites and check-types pass.

Summary

Summary by CodeRabbit

Bug Fixes
- Mode-specific provider profile selections now remain scoped to the current window.
- A window’s explicit selection takes precedence over its opening settings and conflicting shared settings.
- Modes without a window-specific selection use the mapping captured when the window opened, or shared settings if no opening mapping is available.
- Missing, unconfigured, or outdated profiles fall back without replacing the parent task’s profile.
- If saving a selection fails, the previous window-specific selection is restored.
- Imported mode-to-profile mappings are applied to the current window after a successful import. Resetting state clears local selections and refreshes the settings used for future lookups.

ClineProvider now tracks mode-to-profile selections per window. It snapshots shared settings at startup and uses local selections, the snapshot, or shared settings to resolve profiles. Mode switching, profile persistence and activation, history restoration, reset, delegation, imports, and configuration updates use these helpers.

Changes: Window-local mode profiles

Layer / File(s)	Summary
Mode profile state and lookup `src/core/webview/ClineProvider.ts`, `src/core/config/ProviderSettingsManager.ts`, `src/core/webview/__tests__/ClineProvider.spec.ts`, `src/core/config/__tests__/ProviderSettingsManager.spec.ts`	ClineProvider captures the shared mode-to-profile mapping at startup. Local selections take precedence over the snapshot. If a cached profile is stale, lookup consults shared settings. Writes update local and persisted mappings. ProviderSettingsManager returns a copy of the stored mapping. Tests cover precedence, fallback, snapshot-read failure, stale profiles, write failures, reset, and map-copy behavior.
Mode profile flow integration `src/core/webview/ClineProvider.ts`, `src/__tests__/ClineProvider.delegation.spec.ts`, `src/core/webview/__tests__/ClineProvider.apiHandlerRebuild.spec.ts`, `src/core/webview/__tests__/ClineProvider.lockApiConfig.spec.ts`	History restoration, mode switching, profile persistence and activation, reset, and delegation use the window-aware helpers. Tests verify delegation precedence and fallback. Test setups initialize the snapshot.
Import and configuration mapping updates `src/core/config/importExport.ts`, `src/utils/autoImportSettings.ts`, `src/extension.ts`, `src/extension/api.ts`, `src/core/config/__tests__/importExport.spec.ts`, `src/extension/__tests__/api-configuration.spec.ts`	Import paths pass imported mode mappings to ClineProvider after provider-profile import. API configuration updates use `ClineProvider.setModeConfig`. Tests cover import callback behavior and configuration mappings.

Merge Risk: Low · up to 4ba97

Window-local selections work on the covered paths, but unusual timing around startup or concurrent profile changes can still select an unintended profile. This is mergeable with owner awareness of those edge cases.

Explanation

[#2109] ClineProvider prefers window-local selections and the opening snapshot over shared mode mappings. Delegation, mode switching, and history restoration use this lookup. Tests cover local precedence, delegation, missing and stale profiles, and failed writes. If snapshot capture fails, the lookup falls back to shared storage.

Full details: Out of Scope Changes check

Explanation

[#2109] Provider and settings-manager changes support window-local mode selections. API and import changes keep those selections in sync with changes made in the same window. The tests cover these paths. The summary shows no unrelated changes.

Full details: Security Boundaries

Explanation

The changed paths manage mode-to-profile IDs and preserve existing profile storage. Imported mappings pass through providerProfilesSchema before adoption. The diff does not show a secret or PII leak, unvalidated input execution, or an approval or allowlist bypass.

Full details: Lifecycle Resource Cleanup

Explanation

The changed paths add profile-map reads, writes, and snapshots. They do not create lifecycle resources or introduce duplicate work after cancellation, disposal, or restart. The existing mode-switch cancellation checks remain in place.

Full details: Persistence Integrity

Explanation

ClineProvider.setModeConfig can lose a successful mode default during overlapping writes (ClineProvider.ts:2206-2217). If two calls set the same mode to B and the first write fails while the second is pending, the first rollback restores A. The second write can then persist B without restoring the local value. Later lookups use A, and a mode switch can write A over B. Concurrent API.setConfiguration calls can reach this path (api.ts:631-639). The prior import and API propagation concerns are addressed: imports call adoptModeConfigIds after persistence, and API updates call setModeConfig.

Resolution

Serialize each mode's local update and persisted write, or use operation-specific rollback and commit tracking. Add a regression test for overlapping same-ID writes where the first fails and the second succeeds.

Full details: Regression Evidence

Explanation

Two changed behaviors lack focused regression coverage. - ClineProvider.ts:474 captures the opening mode map, but the tests replace the snapshot or call the capture helper directly (ClineProvider.spec.ts:563,4502-4545). They do not verify constructor capture or constructor read failure. - The import entry points now adopt imported mappings (importExport.ts:383-400, extension.ts:280-286). Tests cover the callback and adoption separately, but do not verify that manual or automatic import connects them. A disconnected callback would leave the window using its old snapshot. The previous API concern is addressed: API.setConfiguration calls the provider helper, and api-configuration.spec.ts:40-56 checks subsequent lookups.

Resolution

Add constructor-level tests for opening snapshot isolation and read failure. Add focused tests that exercise manual and automatic import forwarding and verify that imported mappings become the window-local choices.

Review comments at @src/__tests__/ClineProvider.delegation.spec.ts:
- Line 299: The delegation test fixture should expose a distinct local mode
selection instead of forwarding getModeConfigId directly to shared storage. Add
a case with different local and shared IDs, then assert that the delegated child
uses the provider’s local selection, preserving behavior-focused regression
coverage in the existing test harness.

Review comments at @src/core/webview/ClineProvider.ts:
- Line 1840: Update resetState() to clear localModeConfigIds when resetting
stored profiles, so getModeConfigId does not reuse IDs for removed profiles and
handleModeSwitchUnlocked falls back to the reset provider mapping.
- Line 1840: Update the mode configuration lookup around localModeConfigIds so
each window snapshots its initial mode-to-configuration mapping before shared
settings can be changed by another window, then use that snapshot for untouched
modes instead of reading the current shared value. Preserve explicit local
selections and verify delegation still uses the initiating window’s snapshot
after another window changes the target mode.
