[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 remain scoped to the current window.
- A window’s selection takes precedence over its opening settings and conflicting shared settings.
- Modes without a window-specific selection use settings captured when the window opened, or shared settings if no snapshot is available.
- Missing or outdated profiles fall back without replacing the parent task’s profile.
- If saving a selection fails, the previous selection is restored.
- Successfully imported mode-to-profile mappings apply to the current window. Resetting clears local selections and refreshes settings for future lookups.

ClineProvider now tracks mode-to-profile selections per window. It captures a shared mapping at startup and resolves profiles using local selections, the snapshot, or shared settings. Mode changes, profile operations, 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, stale profiles, pending validation, 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. Delegation tests cover local-choice precedence and shared-lookup 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: Moderate · previous review 69023

A window opening while another changes profiles may still select the other window’s profile. Profile validation can also interrupt delegation, and a failed import can leave a new local choice active. Resolve these issues before merging.

Full details: Description check

Explanation

The description links issue #2109 and explains the problem, implementation, limitations, and reported tests. It does not complete the pre-submission checklist or give steps to repeat the tests, but it is otherwise substantially complete.

Full details: Linked Issues check

Explanation

[#2109] asks each VS Code window to keep its own model configuration. ClineProvider now checks its local mode choice and opening snapshot instead of reading the live shared mapping for a mode absent from that snapshot. If the snapshot read fails, getModeConfigId returns no mode-specific profile and does not read the live shared mapping. Tests cover both cases and verify that another window’s later choice does not replace the current window’s profile.

Full details: Out of Scope Changes check

Explanation

The provider-settings snapshot getter, local write and lookup helpers, import adoption, reset handling, API routing, and tests support window-level profile isolation for [#2109]. No unrelated changes are evident in the reviewed diff.

Full details: Security Boundaries

Explanation

No changed path was found that leaks secrets or PII, trusts or executes unvalidated input, or bypasses approval or allowlist controls. Imported mode mappings pass through the existing schema, and profile lookups validate cached IDs against existing profiles.

Full details: Persistence Integrity

Explanation

adoptModeConfigIds can overwrite a newer local choice during an import. If an import writes profile A while setModeConfig queues profile B, the import callback can set the local choice to A while B is still being persisted. The B write then succeeds without restoring the local choice. A later mode switch can activate A and persist it over B. See importExport.ts:232-233 and ClineProvider.ts:2203-2228, 2117-2145, 2566-2569.

Resolution

Coordinate import persistence and adoption with mode writes so local choices follow the persisted write order. Add a regression test for an import that overlaps a successful write for the same mode.

Full details: Regression Evidence

Explanation

Two regression coverage gaps remain. ClineProvider.ts:477 captures the opening snapshot, but the focused tests replace it or call the capture helper directly (ClineProvider.spec.ts:562,4503,4543). They do not verify constructor capture or constructor-time read failure. Manual and automatic import paths also lack tests that verify imported mappings reach window-local choices (importExport.ts:387,400, extension.ts:286, autoImportSettings.ts:44). The existing tests cover callback invocation and adoption separately.

Resolution

Add constructor-level tests for snapshot isolation and read failure. Add focused tests for manual and automatic imports that verify imported mappings become window-local choices.

Full details: Lifecycle Resource Cleanup

Explanation

A cancelled mode switch can repeat profile-list work. In ClineProvider.ts:2118-2121, the switch checks cancellation only after the lookup and a listConfig() call. The new getModeConfigId() also calls listConfig() at line 2193. If the opening snapshot remains pending until the mutation times out, both list calls run after cancellation when the snapshot resolves. Each call reads and parses the stored profiles.

Resolution

Pass the abort signal into getModeConfigId and check it after the snapshot and profile reads. Check the signal again before the caller invokes listConfig(). Add coverage for cancellation while the snapshot is pending.

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.
