[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 the settings captured when the window opened; stale or unavailable selections fall back to shared settings where applicable.
- Missing or outdated profiles fall back without replacing the parent task’s profile.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 through local choices, the snapshot, or shared settings. Mode changes, profile operations, imports, configuration updates, and delegation use provider-level lookup and write helpers.

Changes: Window-local mode profiles

Layer / File(s)	Summary
Mode profile state and persistence `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 mapping at startup and resolves profiles using local choices and the snapshot. It validates cached profiles and serializes writes. ProviderSettingsManager returns a copy of the mapping and invokes callbacks after persistence. Tests cover lookup precedence, stale profiles, pending validation, write failures, concurrent writes, and reset.
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`, `src/core/webview/__tests__/ClineProvider.sticky-profile.spec.ts`	History restoration, mode switching, profile persistence and activation, reset, and delegation use window-aware helpers. Tests cover delegation precedence and fallback, and initialize opening snapshots for mode-related cases.
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 persistence. API configuration updates use `ClineProvider.setModeConfig`. Tests cover callback timing, mapping adoption, and configuration updates.

Merge Risk: Low · up to e4d28

In rare multi-window cases, a mode this window has never seen can overwrite another window's saved profile default for that mode. The PR otherwise isolates profile choices per window. The overwrite is a bounded edge case that is worth fixing before or soon after merge.

Full details: Description check

Explanation

The description links issue #2109 and explains the problem, implementation, limitations, and tests. It omits the pre-submission checklist and documentation-impact section, but the main required information is present.

Full details: Linked Issues check

Explanation

[#2109] asks each VS Code window to retain its own model profile for new tasks and delegated agents. ClineProvider resolves profiles from window-local choices and the opening snapshot. Mode switches, history restoration, and delegation use this lookup. Tests cover isolation from later shared writes, imported choices, and delegation lookup.

Full details: Out of Scope Changes check

Explanation

The settings snapshot and persistence callbacks, import adoption, reset handling, API routing, and related tests support profile isolation for [#2109]. No unrelated changes are evident in the reviewed diff.

Full details: Lifecycle Resource Cleanup

Explanation

No changed path was found that leaks resources or duplicates work after cancellation, disposal, or restart. The mode switch now checks cancellation after the snapshot and profile reads and before the caller lists profiles. Prior failure addressed: ClineProvider.ts:2118-2120 and 2187-2197 pass and check the abort signal. ClineProvider.spec.ts:4524-4547 covers cancellation during both snapshot and profile reads.

Full details: Persistence Integrity

Explanation

A failed mode write can roll back a successful import. In ClineProvider.ts:2228-2241, start with local choice A, then queue a write of B while an import of B holds the storage lock. The import persists and adopts B, but if the queued write fails, the equality check restores A. A later mode switch can activate A and persist it over B. The prior successful-write race is addressed by the persistence callback and the ordering test at ClineProvider.spec.ts:4598-4622.

Resolution

Track the ownership or version of each local update so a failed write cannot undo an intervening import, even when both select the same ID. Add a regression test for a successful import of B followed by a failed overlapping write of B.

Full details: Regression Evidence

Explanation

Import wiring lacks focused regression coverage. The automatic-import test supplies its own callback in ClineProvider.spec.ts:4583-4585, so it cannot detect removal of the callback from extension.ts:286. Extension tests mock autoImportSettings without checking that callback. The explicit-file-path branch in importExport.ts:383-393 also lacks an assertion that imported choices reach the provider; the new manual test covers only the dialog branch. Missing either callback would leave imported mode choices outside the window-local map. Commit e4d28bb6 added constructor snapshot success and failure tests and a manual dialog import test. Those address those parts of the previous failure, but the automatic activation wiring remains unverified.

Resolution

Add an activation-level test that invokes the callback passed to autoImportSettings and verifies provider adoption. Add a focused explicit-file-path import test that verifies imported mappings become 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.
