refactor(code-index): own workspace services through scopes by WebMad · Pull Request #1628 · Zoo-Code-Org/Zoo-Code

WebMad · 2026-09-13T09:21:32Z

Summary

Introduce workspace-owned code-index scopes and migrate registry consumers while preserving real workspace URIs.
Harden registry cleanup against disposal errors and reentrancy; remove unused service creation side effects.
Fix readiness filtering, stale progress callbacks, subscription cleanup, lazy-scope ownership, and task-workspace search resolution.
Add permanent scope, registry, lifecycle, activation, filtering, search, and cross-workspace auto-enable tests.

Validation

60 focused test files: 1,349 tests passed.
All five previously surviving targeted mutations now fail assertions; temporary changes restored.
Repository lint and typecheck hooks passed; no suppression increases; diff whitespace check passed.

Remaining boundaries

Consumers own initialization ordering and single disposal. Activation cleanup waits for activation-started initialization, not later consumer initialization. Manager overlap characterization tests document remaining unsafe cases. Workspace-folder add/remove handling and forced extension-host shutdown guarantees remain outside this change.

Includes the preceding manager-registry extraction commits. No changesets or unrelated files are included.

📝 Summary

Summary by CodeRabbit

New Features
- Code indexing now operates independently for each workspace, improving support for multi-root workspaces.
- Codebase search uses the active or requested workspace’s index and becomes available only when indexing is ready.
- Workspace-specific indexing preferences and status updates are preserved across workspaces.
Bug Fixes
- Extension activation no longer waits for code-index initialization to complete.
- Indexing continues for other workspaces when one workspace encounters an initialization failure.
- Workspace indexes now shut down cleanly, including when initialization is still in progress.

Walkthrough

The pull request replaces CodeIndexManager singleton access with cached, workspace-scoped objects. Activation, tool filtering, search, webview handlers, subscriptions, tests, and cleanup now use the workspace-scope registry.

Changes

Workspace-scoped code indexing

Layer / File(s)	Summary
Scope and manager lifecycle `src/services/code-index/code-index-workspace-scope.ts`, `src/services/code-index/code-index-workspace-scope-registry.ts`, `src/services/code-index/manager.ts`, `src/services/code-index/__tests__/*`	`CodeIndexWorkspaceScope` owns a manager. The registry resolves and caches scopes by workspace path, exposes scope snapshots, blocks lookups during disposal, and aggregates disposal errors. `CodeIndexManager` no longer contains singleton storage or static factory and cleanup methods.
Activation and cleanup wiring `src/extension.ts`, `src/__tests__/extension.spec.ts`, `src/activate/registerCommands.ts`, `src/core/prompts/system.ts`	Activation initializes workspace scopes in the background and waits for pending initialization before disposing all scopes. Prompt generation and new-tab commands no longer create code-index managers.
Workspace-aware tool access `src/core/prompts/tools/filter-tools-for-mode.ts`, `src/core/task/build-tools.ts`, `src/core/tools/CodebaseSearchTool.ts`, `src/core/*/__tests__/`	Tool filtering and search resolve the manager through a workspace scope. `codebase_search` remains available only when the scope manager is enabled, configured, and initialized.
Webview scope control `src/core/webview/ClineProvider.ts`, `src/core/webview/webviewMessageHandler.ts`, `src/core/webview/__tests__/*`	Webview code resolves managers through the active scope. Progress subscriptions track scope identity, reject stale callbacks, and dispose explicitly. Auto-enable handling enumerates registered scopes.

Merge Risk: 🟡 Moderate · up to 1d70c

Some workspace configurations can use the wrong index or lose code search availability, while concurrent startup and shutdown retain lifecycle failures. These issues should be addressed before merging.

Full details: Regression Evidence

Explanation

The side-effect removal is not covered by a focused regression test. The PR removes CodeIndexManager.getInstance(context, cwd) from generatePrompt in src/core/prompts/system.ts and removes the corresponding manager creation from openClineInNewTab in src/activate/registerCommands.ts. These changes stop prompt generation and new-tab creation from creating code-index state, which is relevant to the new scope-ownership lifecycle. The nearest prompt tests only compare prompt snapshots, and the new-tab test only checks webview-panel creation. Neither test asserts that no code-index scope or manager is created. The updated registry mock in registerCommands.spec.ts is not used for such an assertion.

Resolution

Add focused unit coverage at the owning boundaries. In the system-prompt test, mock codeIndexWorkspaceScopeRegistry (or the previous manager factory at the base boundary), call SYSTEM_PROMPT, and assert that no scope or manager is requested while retaining the existing prompt-output assertions. In the openClineInNewTab test, call the function with the registry mock and assert that getScope is not called, while retaining the panel assertions. This will protect the intended removal of code-index creation side effects.

Full details: Lifecycle Resource Cleanup

Explanation

A changed lazy-scope cleanup path can start resources after disposal. src/extension.ts:202-220 records only activation-started initialization promises. Later consumers initialize the same registry scopes directly, for example startIndexing and toggleWorkspaceIndexing in src/core/webview/webviewMessageHandler.ts:3222-3291. If such an initialization is pending during deactivation, the extension cleanup awaits only the startup list, then codeIndexWorkspaceScopeRegistry.disposeAll() calls CodeIndexManager.dispose() and removes the scope. The pending CodeIndexManager.initialize() has no disposed guard and can then continue through service recreation and startIndexingInBackground() (src/services/code-index/manager.ts:119-187), creating a file watcher and indexing task after dispose() has already run. The removed scope is no longer available for later cleanup.

Resolution

Track every scope initialization, including consumer-started lazy initialization, until it settles before disposing the scope. Also make disposal stateful: mark the scope or manager as disposing, prevent initialization from continuing after disposal, and stop or dispose any services created by a late initialization. Ensure the extension deactivation path awaits this lifecycle barrier before calling disposeAll().

Full details: Description check

Explanation

The description provides a clear summary, validation results, scope boundaries, and test counts. It does not follow the repository template because it omits the required Related GitHub Issue, Test Procedure, Pre-Submission Checklist, and documentation-impact sections.

Resolution

Add the approved issue reference, such as Closes: #123``. Add reproducible test steps and environment details. Complete the Pre-Submission Checklist and state whether documentation updates are required. Preserve the existing summary, validation, and remaining-boundaries details under the template sections.

In `@src/core/task/build-tools.ts`:
- Line 101: Update the task workspace-scope flow around
codeIndexWorkspaceScopeRegistry.getScope so each explicit or resumed task cwd is
initialized and awaited through the shared lifecycle before the readiness filter
runs. Ensure the scope is ready before evaluating isInitialized and removing
codebase_search, while preserving existing behavior for already initialized
scopes.

In `@src/extension.ts`:
- Around line 200-205: Update the cleanup callback registered in
context.subscriptions to catch errors from
codeIndexWorkspaceScopeRegistry.disposeAll() and log the failure to the
established output channel, while preserving the existing await of
codeIndexInitializations and disposal flow.

In `@src/services/code-index/code-index-workspace-scope-registry.ts`:
- Line 24: Key cached scopes by the workspace URI rather than resolvedPath:
update the registry boundary to accept a WorkspaceFolder or Uri, derive the key
from the folder URI’s full string including scheme and authority, and preserve
distinct managers, enablement state, and indexes for equal fsPath values. Add a
regression test covering identical fsPath values with different authorities.

In `@src/services/code-index/code-index-workspace-scope.ts`:
- Around line 18-19: Update CodeIndexWorkspaceScope.initialize to store and
reuse the in-flight initialization promise, so concurrent callers share one
operation and cannot start duplicate indexing before the cache is ready. Clear
the stored promise after it settles, allowing later sequential configuration
reloads to initialize again.
