fix(inspector): bring back the actor inspector

[jog1t]

Closes FRONT-763

TL;DR

Added actor inspector tests to the driver test suite to ensure inspector functionality works correctly across different drivers.

What changed?

• Added runActorInspectorTests to the driver test suite
• Created a new test file actor-inspector.ts with comprehensive tests for both manager and actor inspectors
• Enabled studio in the test runtime configuration to support inspector tests
• Fixed a bug in the file system driver's getActorsIterator to check if the state directory exists
• Fixed a validation issue in the manager inspector router to properly handle invalid limit parameters
• Fixed URL path handling in the universal actor proxy to correctly handle leading slashes

How to test?

Run the driver test suite with:

pnpm test

The new tests verify:

• Manager inspector functionality (ping, actor listing, actor creation, etc.)
• Actor inspector functionality (state management, connections, events, RPCs)
• Error handling for both inspectors

Why make this change?

The inspector functionality is a critical part of the developer experience, allowing users to debug and inspect actors. These tests ensure that inspector functionality works consistently across all drivers, improving reliability and preventing regressions.

PR Review: Bring Back the Actor Inspector

Summary

This PR successfully restores actor inspector functionality by adding comprehensive test coverage and implementing missing inspector features. The changes include a new extensive test suite and enhancements to the file system driver's inspector capabilities.

Code Quality Assessment

✅ Strengths

Comprehensive Test Coverage (packages/core/src/driver-test-suite/tests/actor-inspector.ts)

• Excellent test coverage with 570 lines covering both Manager and Actor inspector functionality
• Well-structured test organization with clear separation between Manager and Actor inspector tests
• Good test naming conventions and descriptive scenarios
• Tests cover happy paths, error conditions, and edge cases (404 handling, invalid parameters)

Proper Integration (packages/core/src/driver-test-suite/mod.ts:20,124)

• Clean integration of new test suite into existing test framework
• Follows established patterns for test registration and execution

Enhanced Inspector Token Management (packages/core/src/drivers/file-system/global-state.ts:416-425)

• Robust token generation and persistence logic
• Proper file-based token storage with fallback creation
• Uses secure random string generation

Improved Actor Iteration (packages/core/src/drivers/file-system/global-state.ts:122-150)

• Enhanced getActorsIterator with better file system integration
• Proper error handling for missing directories
• Smart filtering of temporary files (line 131: .filter((id) => !id.includes(".tmp")))

⚠️ Areas for Improvement

Test Organization Issues

• Lines 85-90: Commented out test assertion needs attention:

  // expect.objectContaining({
  // 	id: expect.any(String),
  // 	key: expect.arrayContaining(actorKey2),
  // }),

  This suggests incomplete test logic or a known issue that should be documented.

Skipped Database Tests

• Lines 492, 523: Database-related tests are skipped with test.skip
• While acceptable for current functionality, these should have TODO comments explaining when they'll be implemented

Error Handling Consistency

• Line 242: The actor inspector ping test expects any non-ok response but doesn't validate specific error codes
• Consider testing for specific 404 status codes for better error validation

Security Assessment

✅ Good Security Practices

• Inspector token generation uses cryptographically secure random strings (generateRandomString())
• Proper authorization headers in all test cases (Authorization: Bearer token)
• File system operations use secure temporary file patterns to prevent race conditions

🔒 Security Considerations

• Inspector tokens are stored as plain text files - consider if this meets security requirements for production environments
• Test tokens are hardcoded as "token" - ensure these are only used in test environments

Performance Considerations

✅ Efficient Implementation

• Cursor-based pagination for actor listing (lines 123-150)
• Lazy loading of actor state with proper caching
• Efficient file system operations with temp file filtering

⚡ Potential Optimizations

• getActorsIterator reads the entire directory on each call - consider caching for frequently accessed operations
• Actor state loading could benefit from batch operations for multiple actors

Bug Assessment

🐛 Potential Issues

1. Incomplete Test Logic (actor-inspector.ts:85-90): Commented out assertions may indicate unresolved bugs
2. File System Race Conditions: While temp file handling is improved, concurrent access patterns should be tested
3. Error Response Consistency: Some tests expect generic error responses rather than specific error types

✅ Robust Error Handling

• Proper 404 handling for non-existent actors
• Validation of request parameters (limit validation on line 105)
• Graceful degradation for missing state directories

Test Coverage Analysis

✅ Excellent Coverage

• Manager Inspector: 8 comprehensive tests covering CRUD operations, pagination, builds, and bootstrap
• Actor Inspector: 12 tests covering state management, connections, events, RPCs, and database operations
• Error Scenarios: Good coverage of 404 cases and invalid parameters
• Authentication: All tests properly include authorization headers

📋 Coverage Gaps

• Database functionality tests are skipped (acceptable if feature not ready)
• Large payload testing could be added for stress testing
• WebSocket inspector connections not tested (may be out of scope)

Recommendations

High Priority

1. Resolve Commented Test Logic: Address the commented assertions in actor-inspector.ts:85-90
2. Database Test Implementation: Add timeline for implementing skipped database tests
3. Error Code Validation: Enhance error tests to validate specific status codes

Medium Priority

1. Add Documentation: Include JSDoc comments for new inspector methods
2. Performance Testing: Add tests for large actor collections to validate pagination
3. Concurrent Access Testing: Test inspector behavior under concurrent actor operations

Low Priority

1. Token Security Enhancement: Consider encrypted token storage for production environments
2. Batch Operations: Implement batch actor operations for better performance
3. Metrics Collection: Add metrics for inspector usage patterns

Conclusion

This is a well-implemented restoration of the actor inspector functionality. The code demonstrates good engineering practices with comprehensive testing, proper error handling, and clean integration patterns. The main concerns are minor and related to incomplete test logic and skipped functionality that appears to be intentionally deferred.

Recommendation: Approve with minor fixes - Address the commented test assertions and add documentation for skipped tests.

commit: 997035c

[graphite-app]

The commented-out expectation for actorKey2 should either be uncommented to properly test both actors or removed if not needed. Having commented test assertions can be confusing for future maintainers as it's unclear whether this represents an intentional exclusion or incomplete implementation. If both actors should be verified, consider uncommenting and fixing any issues that might have caused it to be commented out initially.

Suggested change

	// expect.objectContaining({
	// id: expect.any(String),
	// key: expect.arrayContaining(actorKey2),
	// }),
	expect.objectContaining({
	id: expect.any(String),
	key: expect.arrayContaining(actorKey2),
	}),

    .replace(/^\/?registry\/actors/, "")
    .replace(/^\/?actors/, ""); // Remove /registry prefix if present  

🐛 Minor Issues

• Some error tests expect generic error responses rather than specific error types (line 241)
• Database functionality tests are intentionally deferred but properly marked with test.skip

Test Coverage Analysis

✅ Excellent Coverage

• Manager Inspector: 8 comprehensive tests covering CRUD operations, pagination, builds, and bootstrap
• Actor Inspector: 12 tests covering state management, connections, events, RPCs
• Error Scenarios: Good coverage of 404 cases and invalid parameters
• Authentication: All tests properly include authorization headers
• State Management: Tests cover both replace and patch operations for actor state

📋 Coverage Gaps

• Database functionality tests are intentionally skipped (acceptable if feature not ready)
• Large payload testing could be added for stress testing
• WebSocket inspector connections not tested (may be out of scope)

Specific Code Improvements

Test Configuration (packages/core/src/driver-test-suite/mod.ts:160-163)

Good Addition: Studio is enabled in test configuration to support inspector tests:

studio: {
    enabled: true,
    token: () => "token",
},

This ensures the inspector functionality is properly initialized during tests.

Recommendations

High Priority

1. Database Test Implementation: Add timeline for implementing skipped database tests or document why they're deferred
2. Error Code Validation: Enhance error tests to validate specific status codes rather than just non-ok responses

Medium Priority

1. Add Documentation: Include JSDoc comments for new inspector methods
2. Performance Testing: Add tests for large actor collections to validate pagination performance
3. Concurrent Access Testing: Test inspector behavior under concurrent actor operations

Low Priority

1. Token Security Enhancement: Consider encrypted token storage for production environments
2. Batch Operations: Implement batch actor operations for better performance with large datasets
3. Metrics Collection: Add metrics for inspector usage patterns

Conclusion

This is a well-implemented restoration of the actor inspector functionality. The code demonstrates excellent engineering practices with comprehensive testing, proper error handling, robust file system operations, and clean integration patterns. The bug fixes address real issues that would have caused failures in production environments.

The main concerns are minor and related to skipped functionality that appears to be intentionally deferred rather than broken. The atomic write implementation and directory existence checks show careful attention to edge cases and concurrent access patterns.

Recommendation: Approve - The implementation is solid, thoroughly tested, and ready for production use. The comprehensive test suite ensures inspector functionality works consistently across all drivers.

PR Review: Actor Inspector Restoration

I'll conduct a comprehensive review of this PR focusing on code quality, potential bugs, performance, security, and test coverage.

Review Checklist

• Analyze the new test suite (actor-inspector.ts)
• Review driver test suite integration changes
• Examine file system driver improvements
• Check inspector router and manager fixes
• Assess security implications
• Evaluate performance considerations
• Provide overall recommendations

---

Summary

This PR successfully restores actor inspector functionality by adding comprehensive test coverage (570 lines) and implementing missing inspector features. The changes include bug fixes in the file system driver and enhancements to URL path handling.

Code Quality Assessment

✅ Strengths

Comprehensive Test Coverage (packages/core/src/driver-test-suite/tests/actor-inspector.ts)

• Excellent 570-line test suite covering both Manager and Actor inspector functionality
• Well-organized test structure with clear separation between components
• Good test naming conventions and descriptive scenarios
• Tests cover happy paths, error conditions, and edge cases (404 handling, invalid parameters)
• Proper use of authentication headers throughout all tests

Clean Integration (packages/core/src/driver-test-suite/mod.ts:20,124)

• Follows established patterns for test registration and execution
• Clean integration into existing test framework

Enhanced File System Driver (packages/core/src/drivers/file-system/global-state.ts)

• Inspector Token Management (lines 416-425): Robust token generation and persistence with secure random strings
• Improved getActorsIterator (lines 122-150): Enhanced with proper file system integration and smart temp file filtering
• Atomic Write Operations (lines 313-336): Excellent atomic write implementation with proper cleanup on errors

Security Best Practices

• Proper authorization headers in all test cases
• Secure token generation using generateRandomString()
• File system operations use secure temporary file patterns

⚠️ Areas for Improvement

Test Logic Issues

• Lines 81-90 in actor-inspector.ts: Test validates both actors correctly, but the structure is clear and appropriate
• Lines 492, 523: Database-related tests are skipped with test.skip - should have TODO comments explaining implementation timeline

Error Handling Consistency

• Line 241: Actor inspector ping test expects any non-ok response but doesn't validate specific error codes
• Consider testing for specific 404 status codes for better validation

Security Assessment

🔒 Security Considerations

• Inspector tokens are stored as plain text files - consider if this meets security requirements for production
• Test tokens are hardcoded as "token" - ensure these are only used in test environments

✅ Good Security Practices

• Cryptographically secure token generation
• Proper file system operations with race condition prevention
• All inspector endpoints properly require authentication

Performance Analysis

✅ Efficient Implementation

• Cursor-based pagination for actor listing
• Lazy loading of actor state with proper caching
• Efficient file system operations with temp file filtering

⚡ Potential Optimizations

• getActorsIterator reads entire directory on each call - consider caching for frequently accessed operations
• Actor state loading could benefit from batch operations for multiple actors

Bug Assessment

✅ Robust Implementations

• Proper 404 handling for non-existent actors
• Validation of request parameters (limit validation)
• Graceful degradation for missing state directories

Specific Code Improvements

Manager Inspector Router (packages/core/src/inspector/manager.ts:27)

Good Fix: Limit validation properly handles edge cases:

if (!limit || (limit && limit <= 0)) {
    return c.json("Invalid limit", 400);
}

Universal Actor Proxy (packages/core/src/manager/router.ts:1759-1762)

Good Fix: URL path handling now correctly removes prefixes:

url.pathname = url.pathname
    .replace(new RegExp(`^${runConfig.basePath}`, ""), "")
    .replace(/^\/?registry\/actors/, "")
    .replace(/^\/?actors/, ""); // Remove /registry prefix if present

File System Driver (packages/core/src/drivers/file-system/global-state.ts:127-133)

Good Fix: Added existence check for state directory:

// Check if state directory exists first
if (fsSync.existsSync(this.#stateDir)) {
    actorIds = fsSync
        .readdirSync(this.#stateDir)
        .filter((id) => !id.includes(".tmp"))
        .sort();
}

The main concerns are minor and related to skipped functionality that appears to be intentionally deferred.

Recommendation: Approve - The implementation is solid and ready for production use. The skipped database tests are acceptable as they appear to be feature-incomplete rather than broken functionality.
