Summary

First isolated step of the refactoring in #1595, implemented on a fresh branch from upstream main. Related to #1594 and umbrella tracker #1592; this PR does not close or replace #1595 automatically.

  • Extract workspace resolution, per-path caching, manager construction, enumeration and cleanup into CodeIndexManagerRegistry.
  • Remove the static cache and registry methods from CodeIndexManager, and make its constructor public.
  • Migrate callers and test mocks to the registry.
  • Keep the input path unchanged and resolve it into a separate local constant.
  • Add 11 focused registry tests covering missing/empty workspaces, resolution priority, remote URI preservation, explicit paths, cache reuse/isolation, snapshot enumeration, disposal and recreation.

Scope

No feature/workspace scope extraction, status-manager redesign, scanner/provider/orchestrator changes, or other changes from #1595.

Actual workspace URIs are preserved. For explicit paths outside open workspace folders, standard VS Code file URI construction replaces the old hand-built URI object; canonical serialization may differ for unusual paths.

Validation

  • 902 tests passed across 35 relevant suites.
  • After refining the parameterized missing/empty-workspace case, all 11 registry tests passed again.
  • Extension type checking passed.
  • Changed-file ESLint with suppression pruning passed; suppression counts and the suppression file are unchanged.
  • Prettier and whitespace validation passed.
  • Pre-commit monorepo lint passed.
  • Pre-push monorepo type checking passed.

Local checks ran on macOS with Node 24.7.0; the repository requests Node 22.23.1, so CI remains authoritative. No manual extension-host smoke test was performed.

No changeset or changelog changes. AI-assisted implementation and tests.

📝 Summary

Summary by CodeRabbit

  • Improvements

    • Improved code indexing across multiple workspace folders by maintaining separate indexes for each workspace.
    • Improved workspace detection, including active editor context, explicitly selected folders, and remote workspaces.
    • Preserved index reuse and isolation when switching between workspace folders.
    • Improved cleanup and recreation of indexes during extension lifecycle events.
  • Tests

    • Added coverage for workspace selection, caching, remote workspaces, disposal, and index recreation.

Walkthrough

The pull request replaces CodeIndexManager singleton methods with CodeIndexManagerRegistry, which resolves and caches managers per workspace path. Production callers and tests now use the registry APIs.

Changes

Code index registry migration

Layer / File(s) Summary
Registry and manager lifecycle
src/services/code-index/code-index-manager-registry.ts, src/services/code-index/manager.ts, src/services/code-index/__tests__/*, src/eslint-suppressions.json
CodeIndexManagerRegistry resolves workspace folders, caches managers by filesystem path, returns all instances, and disposes them. CodeIndexManager now has a public constructor without singleton methods. Tests cover workspace resolution, caching, URI handling, isolation, and disposal.
Application lookup integration
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/*, src/**/__tests__/*
Extension activation, commands, prompts, tools, and webview code now obtain managers through CodeIndexManagerRegistry. Mocks and spies target the registry APIs.

Merge Risk: 🔵 Low · up to 8637e

A narrow remote or virtual workspace configuration could use another workspace’s enablement state; the bounded issue should be fixed or explicitly accepted.

- Around line 768-769: Replace the explicit any assertions on sharedContext in
both CodeIndexManagerRegistry.getInstance calls with a correctly typed
vscode.ExtensionContext or a typed test helper, preserving the existing registry
test behavior and satisfying the no-explicit-any rule.

In `@src/services/code-index/code-index-manager-registry.ts`:
- Line 10: Update the registry lookup around resolveWorkspaceFolder() to accept
and preserve the full vscode.Uri, key instances by folderUri.toString(true), and
continue passing folderUri.fsPath to CodeIndexManager. Update extension.ts
callers accordingly and add a regression test proving equal fsPath values with
different authorities create distinct managers.
