Closes #1594
Related umbrella tracker: #1592 (not closed by this PR).

Description

  • Extract workspace resolution, manager construction, per-path instance caching, enumeration and cleanup into CodeIndexManagerRegistry, following the existing Registry convention.
  • Keep CodeIndexManager responsible for a single workspace; make its constructor public and migrate all static registry callers and mocks.
  • Use a private early-return workspace-folder resolver and return cached/new managers directly without non-null assertions.
  • Add 12 isolated tests with fresh extension contexts covering resolution priority, remote URI preservation, explicit paths outside workspace folders, reuse/isolation, enumeration, disposal, repeated cleanup and recreation.

Indexing, scanner, provider and orchestrator behavior is not redesigned here. One deliberate implementation detail: vscode.Uri.file replaces the hand-built fallback URI for explicit paths outside open workspace folders. Its canonical serialization can change URI-derived keys for unusual paths; real workspace folder URIs are preserved.

Test Procedure

Local validation on macOS (Node 24.7.0; repository requests Node 22.23.1, so CI remains authoritative):

  • 899 tests passed across 35 suites: registry/manager, activation, extension, ClineProvider, webview message handler, tools and prompts.
  • Registry-only V8 coverage: 100% statements, branches, functions and lines.
  • Type checking passed; pre-push hook also ran monorepo check-types successfully.
  • Changed-file ESLint with prune-suppressions passed; suppression file unchanged. Pre-commit hook also ran monorepo lint successfully.
  • Prettier and git diff --check passed.

Registry tests: run pnpm exec vitest run services/code-index/__tests__/manager-registry.spec.ts services/code-index/__tests__/manager.spec.ts from src.

Full CI/Codecov results are pending; no manual extension-host smoke test was performed.

Pre-Submission Checklist

  • Issue Linked / Approval: [ENHANCEMENT] Extract workspace-scoped CodeIndexManager registry #1594 is linked and claimed; maintainer approval/assignment is pending.
  • Scope: One focused registry extraction.
  • Self-Review: Reviewed the diff and consumer migration.
  • Testing: New tests and updated existing mocks.
  • Documentation Impact: Considered; no user-facing documentation required.
  • Contribution Guidelines: Reviewed.

Visual Snapshots

📝 Summary

Summary by CodeRabbit

  • Improvements
    • Code indexing now handles multiple workspaces more consistently, including active and explicitly selected workspace folders.
    • Indexing resources are cleaned up more reliably when the extension is deactivated or settings change.
    • Cleanup continues even if one indexing resource fails, with disposal failures collected for clearer diagnostics.
    • Codebase search, prompts, and related tools now use the same workspace-aware indexing behavior.

Walkthrough

The change extracts workspace-scoped manager ownership into CodeIndexManagerRegistry, updates all consumers, adds disposal error aggregation, and prevents disposed managers from continuing work.

Changes

Code index registry and lifecycle

Layer / File(s) Summary
Registry ownership and lifecycle
src/services/code-index/code-index-manager-registry.ts, src/services/code-index/manager.ts, src/services/code-index/errors/*
The registry resolves and caches workspace managers. CodeIndexManager supports direct construction and disposal guards. Disposal failures are aggregated into CodeIndexDisposalError.
Consumer migration
src/extension.ts, src/activate/registerCommands.ts, src/core/prompts/system.ts, src/core/task/build-tools.ts, src/core/tools/CodebaseSearchTool.ts, src/core/webview/*
Extension activation, commands, prompts, tools, and webview code now use CodeIndexManagerRegistry. Deactivation disposes all registered managers.
Registry and lifecycle validation
src/services/code-index/__tests__/*, src/__tests__/extension.spec.ts, src/activate/__tests__/*, src/core/webview/__tests__/*, src/core/task/__tests__/Task.spec.ts, src/eslint-suppressions.json
Tests cover workspace selection, manager reuse, disposal, error aggregation, deactivation cleanup, and updated mocks.

Merge Risk: 🟡 Moderate · up to 39aab

Extension cleanup can leave indexing resources active, while retained managers can still clear index data after disposal. Resolve these lifecycle failures before merge.

Full details: Lifecycle Resource Cleanup

Explanation

FAIL: A changed deactivation path can create resources after disposal. activate() starts void manager.initialize(contextProxy) without awaiting it. The PR removes context.subscriptions.push(manager) and calls synchronous CodeIndexManagerRegistry.disposeAll() at the start of deactivate(). CodeIndexManager.dispose() has no disposed flag or cancellation. If deactivation occurs while initialize() awaits configuration, cache setup, ignore setup, or embedder validation, the method continues afterward. _recreateServices() can then create a file watcher and orchestrator, and initialize() can start background indexing after disposeAll() has completed. The new watcher and indexing task are not cleaned up. A second re-entry path exists: disposeAll() clears the registry before calling manager.dispose(). An active manager can emit a stop-status event, and ClineProvider then calls getCurrentWorkspaceCodeIndexManager(), which creates and retains a new manager while deactivation is running.

Resolution

Make manager disposal cancel and invalidate all in-flight initialization and restart work. Set a disposed state before stopping resources, check it after every awaited initialization step and before creating or starting services, and dispose any locally created watcher, provider, ignore controller, or orchestrator when cancellation is detected. Track initialization/restart promises and await their settlement during registry cleanup, or make cleanup async. Make dispose() idempotent and ensure all manager-owned resources are disposed even when one cleanup step fails. Prevent CodeIndexManagerRegistry.getInstance() from creating managers during disposal, including from progress callbacks; reset that state only for a deliberate subsequent activation.

Addressed the three review findings in 0715555:

  • Registry cleanup now runs during extension deactivation instead of subscribing individual managers. Cleanup failures are logged without preventing the remaining extension cleanup.
  • Registry disposal snapshots and clears the map first, attempts every manager, and rethrows the first failure afterward. Added tests for failure isolation and clearing before callbacks.
  • Replaced the shared-context casts with a typed test context; existing no-explicit-any suppressions in the manager spec decreased from 89 to 81.

Validation: 49 focused tests passed, TypeScript passed, and monorepo lint/type-check hooks passed. CI for the new commit still needs to complete.

144-144: 🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Match the registry return contract.

CodeIndexManagerRegistry.getInstance returns undefined when no workspace resolves, but this mock returns null. This mismatch can hide code that handles undefined differently from null. Return undefined from the mock.

Proposed fix
-				getInstance: vi.fn().mockReturnValue(null),
+				getInstance: vi.fn().mockReturnValue(undefined),

Addressed the outside-diff review finding in b583717: the registry mock now returns undefined, matching the real unresolved-workspace contract. All 14 extension tests and monorepo lint/type checks pass locally. The diagnostic assertion finding was already fixed in 8ae217c and its thread is now resolved. Waiting for CI and automated review of the latest commit.

Final validation update for b583717: all test/build/security checks, Linux and Windows coverage jobs, Codecov patch checks, and mutation-diff are passing. All known review findings have been addressed. The repository review gate still reports "Required CI passed. Waiting for automated review of the latest commit." Maintainer review/review-process follow-up is needed; no review-state labels or gate settings have been changed.

Guard clearIndexData() after disposal

dispose() leaves _configManager, _orchestrator, and _cacheManager available. A retained CodeIndexManager can therefore pass assertInitialized() and invoke CodeIndexOrchestrator.clearIndexData() and CacheManager.clearCacheFile() after disposal. If _disposed is true, return before any clearing operation.

Scope update: 93380a9 reverts the initialization/disposal cancellation changes from 434d65c, including their dedicated tests, at the contributor's request to keep this PR focused on registry extraction. Registry-owned cleanup, aggregate disposal errors, and the registry rename are retained.

This supersedes my earlier comment claiming the lifecycle race was addressed: the pending-initialization vs disposal race remains unresolved and needs separate follow-up/scope agreement with maintainers. This is not a request to bypass the pre-merge check. Locally, 593 code-index tests, lint and type checking pass after the revert.

Guard asynchronous service creation after disposal.

Keep the new SembleProvider local until initialize() completes. If disposal occurred, dispose the local provider and return before assigning _sembleProvider. After validateEmbedder() completes, apply the same check. Dispose fileWatcher and rooIgnoreController, then return before assigning the orchestrator or search service. Otherwise, disposal can leave an initialized provider unreachable or attach services to a disposed manager.

Disposition of review #1595 (review): both outside-diff findings (reject clearIndexData after disposal; guard asynchronous service creation after disposal) are deferred from this PR by the contributor’s explicit scope decision. The lifecycle guards were intentionally reverted in 93380a9. These risks remain unresolved; we are not claiming the findings are false or fixed. They require separate lifecycle work under #1592 and maintainer agreement on whether this PR can proceed. No production changes or empty commits are being made for these findings. We will rerun CI on the existing head; that does not resolve or override the lifecycle pre-merge review concern.

…g#1594)

Separate workspace resolution and instance ownership from CodeIndexManager. Update consumers, aggregate disposal failures, and add focused registry and cleanup tests. Lifecycle cancellation is deferred from this PR.

This PR removes context.subscriptions.push(manager) from activate(). Is there a test asserting context.subscriptions stays empty after getInstance()? Without one, re-adding that push (causing double-disposal) would go undetected.

it("clears the registry before disposal callbacks run", () => {
const manager = CodeIndexManagerRegistry.getInstance(context, first.uri.fsPath)!

If a mutation removes the disposal loop from disposeAll(), dispose() is never called and this expect never runs — Vitest still reports the test as passing. An expect.assertions(1) guard (or an outer expect(manager.dispose).toHaveBeenCalledTimes(1) after disposeAll()) would catch that.

Also: if this assertion fails, disposeAll()'s try-catch catches it and re-throws it wrapped in CodeIndexDisposalError, making the failure message confusing.

const folder = this.resolveWorkspaceFolder(workspacePath)

|| here would silently overwrite an explicitly passed empty string "" with the fallback. Is ?? intended?

Suggested change
workspacePath = workspacePath || folder?.uri.fsPath
const resolvedPath = workspacePath ?? folder?.uri.fsPath
if (!resolvedPath) {
return undefined
}

(Then use resolvedPath in the rest of the method rather than re-assigning the parameter.)

Is codeIndexManagers still used anywhere? Now that CodeIndexManagerRegistry.getAllInstances() owns enumeration, the array on line 200 and this push look like dead code.

The old context.subscriptions.push(manager) per-manager ensured disposal even if deactivate() was never called (host crash, process kill). Now disposeAll() is the only path. Would a single wrapper disposable during activate() restore the safety net with no other changes needed?

Suggested change
CodeIndexManagerRegistry.disposeAll()
context.subscriptions.push({ dispose: () => { try { CodeIndexManagerRegistry.disposeAll() } catch { /* logged below */ } } })
try {
CodeIndexManagerRegistry.disposeAll()

When disposeAll() throws a CodeIndexDisposalError, its .message starts with "Failed to dispose code index managers…" already — so this template would repeat the prefix. Would String(error) avoid the duplication?

const { activate, deactivate } = await import("../extension")
await activate(mockContext)
vi.mocked(CodeIndexManagerRegistry.disposeAll).mockImplementationOnce(() => {
throw new Error("index cleanup failed")

This mocks a plain Error, but in production disposeAll() throws CodeIndexDisposalError whose .message already starts with "Failed to dispose code index managers…". Does the catch block in extension.ts double-prefix the log in that real case?
