[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 profile selection takes precedence over its opening settings and conflicting shared settings.
- Modes without a window-specific selection use the profile mapping captured when the window opened, or shared settings if no opening mapping is available.
- Missing, unconfigured, or outdated saved profiles fall back without replacing the parent task’s profile.
- If saving a selection fails, the previous window-specific selection is restored.

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, and delegation use these helpers.

Changes: Window-local mode profiles

Layer / File(s)	Summary
Mode profile state and lookup `src/core/config/ProviderSettingsManager.ts`, `src/core/config/__tests__/ProviderSettingsManager.spec.ts`, `src/core/webview/ClineProvider.ts`, `src/core/webview/__tests__/ClineProvider.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/core/webview/__tests__/ClineProvider.apiHandlerRebuild.spec.ts`, `src/core/webview/__tests__/ClineProvider.lockApiConfig.spec.ts`, `src/__tests__/ClineProvider.delegation.spec.ts`	History restoration, mode switching, profile persistence and activation, reset, and delegation use the window-aware helpers. Test setups initialize the snapshot. Delegation tests verify local precedence and shared-setting fallback.

Possibly related issues

Zoo-Code-Org/Zoo-Code#2152: The issue concerns per-view mode and provider profile state. This change adds per-window mode-to-profile state; its separate secret-handling and initial-persistence requirements are not covered in the supplied change summary.
Zoo-Code-Org/Zoo-Code#2314: The issue concerns cross-window loss of persisted mode and profile selections. This change adds in-memory per-window selections but does not persist the per-window map across reloads.
Zoo-Code-Org/Zoo-Code#2303: The issue reports provider profile changes crossing VS Code windows. This change addresses cross-window mode-profile selection; workspace-scoped storage and restart persistence remain outside the described changes.

Merge Risk: Moderate · up to ed241

A concurrent profile activation can be lost, allowing a later task to use the wrong model configuration. Protect newer window-local choices before merging.

Explanation

[#2109] ClineProvider resolves mode profiles from a window-local selection or opening snapshot before using shared storage. Mode switching, history restoration, and delegation use the lookup. Regression tests cover local precedence, snapshot behavior, stale profiles, and delegated tasks. If the opening snapshot cannot be read, lookup falls back to shared storage.

Explanation

[#2109] The provider and settings-manager changes implement window-local mode-profile lookup. The test changes cover the lookup, delegation, storage reads, and test setup. The whole-PR summary shows no unrelated changes.

Full details: Lifecycle Resource Cleanup

Explanation

The changed lifecycle paths do not introduce a concrete resource leak or duplicate work after cancellation, disposal, or restart. The new snapshot reads profile data under the existing lock. Reset clears the local map and captures a new snapshot. Mode switching retains its cancellation checks.

Full details: Persistence Integrity

Explanation

The new snapshot can hide and overwrite an imported mode default. importExport.ts:206-230 persists imported mode mappings without refreshing ClineProvider's snapshot. If an imported custom mode was absent at window startup, getModeConfigId returns undefined (ClineProvider.ts:2183-2190). A later mode switch writes the current profile over the imported mapping (ClineProvider.ts:2149-2157). setConfiguration also writes mappings without updating the snapshot (src/extension/api.ts:631-639). The prior failed-write concern is addressed for the tested sequential case: setModeConfig restores the previous local choice on rejection, and the new test covers it.

Resolution

Propagate successful imports and setConfiguration mode-map updates to the affected window's local view. Preserve isolation from writes by other windows. Add regression tests for imported and API-provided defaults, including a mode absent from the opening snapshot.

Full details: Regression Evidence

Explanation

Two changed behaviors lack focused regression coverage. ClineProvider.ts:474 captures the opening snapshot, but the snapshot tests replace it or call the capture helper directly (ClineProvider.spec.ts:563,4502-4532). They do not verify constructor capture. The new snapshot lookup also ignores later API.setConfiguration mappings because that API writes directly to shared storage (api.ts:631-639). Its test uses a fake provider and checks only manager calls (api-configuration.spec.ts:13-43).

Resolution

Add constructor-level tests for opening snapshot isolation and snapshot-read failure. Make API configuration writes update the window-local choice, and add a regression test that verifies a later mode lookup uses the API-supplied mapping.

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.
