feat: add srtd doctor command for setup diagnostics

[t1mmen]

User description

Summary

New srtd doctor command that validates your SRTD configuration and diagnoses setup issues.

What it does

Runs 10 diagnostic checks in sequence:

1. Config file exists - Verifies srtd.config.json is present
2. Config schema valid - Validates config against Zod schema
3. Template directory exists - Checks templateDir path exists
4. Migration directory exists - Checks migrationDir path exists
5. Template directory readable - Verifies read permissions
6. Migration directory writable - Verifies write permissions
7. Build log valid - Validates .srtd.buildlog.json integrity
8. Local build log valid - Validates .srtd.buildlog.local.json integrity
9. Database connection - Tests connectivity with 5s timeout
10. Template count - Confirms at least one template exists

PR Code Suggestions ✨

Explore these optional code suggestions:

Category	Suggestion	Impact
High-level	Run diagnostic checks in parallel Refactor the runAllChecks function to execute all diagnostic checks concurrently using Promise.all. This will improve performance by not waiting for each I/O-bound operation, like the database check, to complete sequentially. Examples: src/utils/doctorChecks.ts [315-335] export async function runAllChecks( projectRoot: string, config: CLIConfig, warnings: ValidationWarning[] ): Promise<DoctorCheckResult[]> { const results: DoctorCheckResult[] = []; // Run checks in order results.push(await checkConfigExists(projectRoot)); results.push(await checkConfigSchemaValid(warnings)); ... (clipped 11 lines) Solution Walkthrough: Before: export async function runAllChecks( projectRoot: string, config: CLIConfig, warnings: ValidationWarning[] ): Promise<DoctorCheckResult[]> { const results: DoctorCheckResult[] = []; // Run checks in order, awaiting each one results.push(await checkConfigExists(projectRoot)); results.push(await checkConfigSchemaValid(warnings)); results.push(await checkTemplateDirExists(projectRoot, config)); results.push(await checkMigrationDirExists(projectRoot, config)); // ... and so on for all 10 checks results.push(await checkDatabaseConnection(config)); results.push(await checkTemplateCount(projectRoot, config)); return results; } After: export async function runAllChecks( projectRoot: string, config: CLIConfig, warnings: ValidationWarning[] ): Promise<DoctorCheckResult[]> { const checkPromises = [ checkConfigExists(projectRoot), checkConfigSchemaValid(warnings), checkTemplateDirExists(projectRoot, config), checkMigrationDirExists(projectRoot, config), checkTemplateDirReadable(projectRoot, config), checkMigrationDirWritable(projectRoot, config), checkBuildLogValid(projectRoot, config), checkLocalBuildLogValid(projectRoot, config), checkDatabaseConnection(config), checkTemplateCount(projectRoot, config), ]; return Promise.all(checkPromises); } Suggestion importance[1-10]: 7 __ Why: The suggestion correctly identifies a performance bottleneck where independent, I/O-bound checks are run sequentially, and proposes a valid parallel execution strategy using Promise.all that would significantly speed up the doctor command.	Medium
General	✅ Avoid using process.exit() directly Suggestion Impact: The commit implemented the core suggestion by replacing process.exit(exitCode) with process.exitCode = exitCode. The implementation differs slightly from the suggestion - instead of removing the exitCode variable and setting process.exitCode conditionally, the commit kept the exitCode variable and assigned it to process.exitCode at the end. The commit also added explanatory comments about the change. code diff: - process.exit(exitCode); + // Use process.exitCode to allow event loop to drain naturally + // This enables proper cleanup and makes testing easier + process.exitCode = exitCode; Replace the direct process.exit() call in the doctor command's action handler with process.exitCode to allow for graceful process termination and improve testability. src/commands/doctor.ts [51-91] export const doctorCommand = new Command('doctor') .description('Validate SRTD setup and configuration') .action(async () => { - let exitCode = 0; - try { await renderBranding({ subtitle: 'Doctor' }); const projectRoot = await findProjectRoot(); const { config, warnings } = await getConfig(projectRoot); console.log(); renderSeparator(); console.log(); // Run all checks const results = await runAllChecks(projectRoot, config, warnings); // Display results for (const result of results) { renderCheckResult(result); } console.log(); renderSeparator(); // Summary renderSummary(results); // Set exit code based on failures const hasFailures = results.some(r => !r.passed); - exitCode = hasFailures ? 1 : 0; + if (hasFailures) { + process.exitCode = 1; + } } catch (error) { console.log(); console.log(chalk.red(`${figures.cross} Error running doctor:`)); console.log(chalk.red(getErrorMessage(error))); - exitCode = 1; + process.exitCode = 1; } - - process.exit(exitCode); }); [Suggestion processed] Suggestion importance[1-10]: 7 __ Why: The suggestion correctly identifies that using process.exit() is a bad practice that can interfere with test runners and proposes the modern process.exitCode alternative, which improves testability and robustness.	Medium
Possible issue	✅ Fix incorrect writability check logic Suggestion Impact: The commit directly implements the suggestion by adding a fileWritten flag, moving the unlink operation to a finally block with error handling, and ensuring cleanup failures don't affect the writability check result. code diff: + let fileWritten = false; try { await fs.writeFile(testFile, 'test'); - await fs.unlink(testFile); + fileWritten = true; return { name: 'Migration directory writable', passed: true, @@ -138,6 +139,13 @@ passed: false, message: error instanceof Error ? error.message : 'Cannot write to migration directory', }; + } finally { + // Cleanup test file if it was written (ignore cleanup errors) + if (fileWritten) { + await fs.unlink(testFile).catch(() => { + // Intentionally ignore - cleanup failure doesn't affect writability result + }); + } } Refactor checkMigrationDirWritable to separate the write check from the file cleanup. Use a finally block to ensure the test file is removed without affecting the check's outcome. src/utils/doctorChecks.ts [121-142] export async function checkMigrationDirWritable( projectRoot: string, config: CLIConfig ): Promise<DoctorCheckResult> { const migrationPath = path.join(projectRoot, config.migrationDir); const testFile = path.join(migrationPath, '.srtd-doctor-test'); + let fileWritten = false; try { await fs.writeFile(testFile, 'test'); - await fs.unlink(testFile); + fileWritten = true; return { name: 'Migration directory writable', passed: true, }; } catch (error) { return { name: 'Migration directory writable', passed: false, message: error instanceof Error ? error.message : 'Cannot write to migration directory', }; + } finally { + if (fileWritten) { + await fs.unlink(testFile).catch(() => { + /* ignore cleanup errors */ + }); + } } } [Suggestion processed] Suggestion importance[1-10]: 6 __ Why: The suggestion correctly identifies a logic bug where a failing cleanup operation (unlink) would incorrectly cause the writability check to fail, and it provides a robust fix using a finally block.

PR Reviewer Guide 🔍

Here are some key observations to aid the review process:

⏱️ Estimated effort to review: 3 🔵🔵🔵⚪⚪

🧪 PR contains tests

🔒 No security concerns identified

⚡ Recommended focus areas for review Race Condition Risk The database connection check uses Promise.race() with a timeout, but doesn't cancel the ongoing connection attempt. If the timeout fires first, the connection promise continues running in the background, potentially causing resource leaks or unexpected behavior. Consider implementing proper cancellation or cleanup of the connection attempt when timeout occurs. const timeoutPromise = new Promise<'timeout'>(resolve => { setTimeout(() => resolve('timeout'), timeoutMs); }); const connectionPromise = db.testConnection(); const result = await Promise.race([connectionPromise, timeoutPromise]); if (result === 'timeout') { return { name: 'Database connection', passed: false, message: `Connection timed out after ${timeoutMs}ms`, hint: 'Check if database is running: `supabase status` or `docker ps`', }; } Exit Code Handling The command sets process.exitCode but continues execution. While the comment mentions this allows event loop to drain, there's no guarantee that async cleanup completes before the process exits. Consider using explicit async cleanup or documenting the expected behavior more clearly. // Set exit code based on failures const hasFailures = results.some(r => !r.passed); exitCode = hasFailures ? 1 : 0; } catch (error) { console.log(); console.log(chalk.red(`${figures.cross} Error running doctor:`)); console.log(chalk.red(getErrorMessage(error))); exitCode = 1; } // Use process.exitCode to allow event loop to drain naturally // This enables proper cleanup and makes testing easier process.exitCode = exitCode; Silent Error Handling In checkTemplateCount, the catch block at line 327 catches all errors without distinguishing between different failure modes (permissions vs. non-existent directory). This could mask the actual problem. Consider providing more specific error messages based on error type. } catch { return { name: 'Template count', passed: false, message: `Cannot read template directory: ${config.templateDir}`, hint: 'Check directory permissions or ensure it exists', }; }

Tasks

• Check bot feedback concerns
• Provide comprehensive feedback

Summary

Great implementation overall! The srtd doctor command is well-structured with pure, testable check functions and comprehensive test coverage. You've properly addressed the writability check feedback from the bots. I found a few issues worth addressing:

Critical Issues

1. Database connection resource leak 🔴

Location: src/utils/doctorChecks.ts:258-299

The database connection promise continues running even after timeout, potentially leaking connections.

const result = await Promise.race([connectionPromise, timeoutPromise]);

if (result === 'timeout') {
  // connectionPromise is still running! db.dispose() happens in finally,
  // but the connection attempt may still be in progress
  return { ... };
}

Issue: When timeout fires, the connection promise keeps running in the background. The db.dispose() in the finally block may try to dispose a pool that's still initializing.

Suggested fix:

export async function checkDatabaseConnection(
  config: CLIConfig,
  timeoutMs = 5000
): Promise<DoctorCheckResult> {
  const db = DatabaseService.fromConfig(config);
  let timedOut = false;

  try {
    const timeoutPromise = new Promise<'timeout'>(resolve => {
      setTimeout(() => {
        timedOut = true;
        resolve('timeout');
      }, timeoutMs);
    });

    const result = await Promise.race([db.testConnection(), timeoutPromise]);

    if (result === 'timeout') {
      // Give a moment for connection cleanup before disposal
      await new Promise(resolve => setTimeout(resolve, 100));
      return {
        name: 'Database connection',
        passed: false,
        message: `Connection timed out after ${timeoutMs}ms`,
        hint: 'Check if database is running: `supabase status` or `docker ps`',
      };
    }

    // ... rest of logic
  } finally {
    // Ensure we give racing promise time to settle before disposal
    if (timedOut) {
      await new Promise(resolve => setTimeout(resolve, 50));
    }
    await db.dispose();
  }
}

High Priority

2. Parallel check execution for better performance 🟡

Location: src/utils/doctorChecks.ts:340-360

The bot suggestion to run checks in parallel is valid. Most checks are independent I/O operations that could run concurrently.

However, I'd recommend a hybrid approach instead of pure Promise.all:

export async function runAllChecks(
  projectRoot: string,
  config: CLIConfig,
  warnings: ValidationWarning[]
): Promise<DoctorCheckResult[]> {
  // Phase 1: Quick filesystem checks (parallel)
  const [
    configExistsResult,
    configSchemaResult,
    templateExistsResult,
    migrationExistsResult,
  ] = await Promise.all([
    checkConfigExists(projectRoot),
    checkConfigSchemaValid(warnings),
    checkTemplateDirExists(projectRoot, config),
    checkMigrationDirExists(projectRoot, config),
  ]);

  // Phase 2: Permission checks (parallel, but after existence checks)
  const [templateReadableResult, migrationWritableResult] = await Promise.all([
    checkTemplateDirReadable(projectRoot, config),
    checkMigrationDirWritable(projectRoot, config),
  ]);

  // Phase 3: File validation + DB + template count (parallel)
  const [buildLogResult, localBuildLogResult, dbResult, templateCountResult] = await Promise.all([
    checkBuildLogValid(projectRoot, config),
    checkLocalBuildLogValid(projectRoot, config),
    checkDatabaseConnection(config),
    checkTemplateCount(projectRoot, config),
  ]);

  // Return in display order
  return [
    configExistsResult,
    configSchemaResult,
    templateExistsResult,
    migrationExistsResult,
    templateReadableResult,
    migrationWritableResult,
    buildLogResult,
    localBuildLogResult,
    dbResult,
    templateCountResult,
  ];
}

Rationale: This gives you ~3x speedup while maintaining logical grouping and proper display order.

Medium Priority

3. Better error context for template count check 🟡

Location: src/utils/doctorChecks.ts:327-334

The catch-all error handler loses valuable debugging info:

} catch {  // ← error is swallowed
  return {
    name: 'Template count',
    passed: false,
    message: `Cannot read template directory: ${config.templateDir}`,
    hint: 'Check directory permissions or ensure it exists',
  };
}

Suggestion: Capture and use the error:

} catch (error) {
  const errorMsg = error instanceof Error ? error.message : 'Unknown error';
  return {
    name: 'Template count',
    passed: false,
    message: `Cannot read template directory: ${errorMsg}`,
    hint: 'Check directory permissions or ensure it exists',
  };
}

4. Writability check cleanup - good fix! ✅

Location: src/utils/doctorChecks.ts:128-158

Your fix for the writability check is excellent and addresses the bot feedback perfectly. The finally block with proper error handling ensures cleanup doesn't affect the check result. Well done!

Low Priority / Style

5. Consistent error message format 🟢

Some checks use error.message directly, others provide custom messages. Consider standardizing:

• src/utils/doctorChecks.ts:119 - Uses error.message
• src/utils/doctorChecks.ts:147 - Uses error.message
• src/utils/doctorChecks.ts:293 - Uses error.message

This is fine, but consider adding more context like: "Cannot read template directory: ${error.message}" for better UX.

6. Code style compliance ✅

All code follows the project's Biome config perfectly:

• Single quotes ✅
• 2-space indent ✅
• 100 char line width ✅
• Proper semicolons ✅

Test Quality

Excellent test coverage! ✅

• 29 unit tests covering all 10 checks with both pass/fail scenarios
• E2E tests verify actual CLI execution
• Edge cases well covered (missing files, timeouts, cleanup failures)
• Mocking strategy is clean and effective

The test at src/__tests__/doctorChecks.test.ts:227-237 specifically tests the cleanup failure scenario - great work!

Documentation

Changeset ✅

Well-written, follows conventional commit format, appropriate minor version bump.

Bot Feedback Review

1. Qodo compliance concerns - Mostly false positives:

   • "Connection string exposure" - Not an issue, error handling is appropriate
   • "Error message exposure" in doctor.ts:86 - This is a diagnostic tool, showing errors is expected
   • "Incomplete cleanup handling" - You fixed this! ✅

2. Codecov: 67.76% patch coverage - The missing lines are mostly in doctor.ts presentation logic (rendering functions). This is acceptable for a diagnostic command.

Recommendations

1. Must fix: Database connection timeout race condition (Issue Refactoring #1)
2. Should consider: Parallel check execution for 2-3x speed improvement (Issue Update readme #2)
3. Nice to have: Better error context in template count check (Issue CI, testing, prep for release #3)

Overall Assessment

This is a high-quality PR that adds genuine value. The diagnostic command is well-architected, thoroughly tested, and follows project conventions. The writability check fix shows you're responsive to feedback. Once the database timeout issue is addressed, this will be production-ready.

Recommendation: Approve after fixing the database connection race condition.

    message: `Cannot read template directory: ${config.templateDir}`,
    hint: 'Check directory permissions or ensure it exists',
  };
}

Suggestion: Capture and use the error:

} catch (error) {
  const errorMsg = error instanceof Error ? error.message : 'Unknown error';
  return {
    name: 'Template count',
    passed: false,
    message: `Cannot read template directory: ${errorMsg}`,
    hint: 'Check directory permissions or ensure it exists',
  };
}

4. Writability check cleanup - good fix! ✅

Location: src/utils/doctorChecks.ts:128-158

Your fix for the writability check is excellent and addresses the bot feedback perfectly. The finally block with proper error handling ensures cleanup doesn't affect the check result. Well done!

Low Priority / Style

5. Consistent error message format 🟢

Some checks use error.message directly, others provide custom messages. Consider standardizing:

• src/utils/doctorChecks.ts:119 - Uses error.message
• src/utils/doctorChecks.ts:147 - Uses error.message
• src/utils/doctorChecks.ts:293 - Uses error.message

This is fine, but consider adding more context like: "Cannot read template directory: ${error.message}" for better UX.

6. Code style compliance ✅

All code follows the project's Biome config perfectly:

• Single quotes ✅
• 2-space indent ✅
• 100 char line width ✅
• Proper semicolons ✅

Test Quality

Excellent test coverage! ✅

• 29 unit tests covering all 10 checks with both pass/fail scenarios
• E2E tests verify actual CLI execution
• Edge cases well covered (missing files, timeouts, cleanup failures)
• Mocking strategy is clean and effective

The test at src/__tests__/doctorChecks.test.ts:227-237 specifically tests the cleanup failure scenario - great work!

Documentation

Changeset ✅

Well-written, follows conventional commit format, appropriate minor version bump.

Bot Feedback Review

1. Qodo compliance concerns - Mostly false positives:

   • "Connection string exposure" - Not an issue, error handling is appropriate
   • "Error message exposure" in doctor.ts:86 - This is a diagnostic tool, showing errors is expected
   • "Incomplete cleanup handling" - You fixed this! ✅

2. Codecov: 67.76% patch coverage - The missing lines are mostly in doctor.ts presentation logic (rendering functions). This is acceptable for a diagnostic command.

Recommendations

1. Must fix: Database connection timeout race condition (Issue Refactoring #1)
2. Should consider: Parallel check execution for 2-3x speed improvement (Issue Update readme #2)
3. Nice to have: Better error context in template count check (Issue CI, testing, prep for release #3)

Overall Assessment

This is a high-quality PR that adds genuine value. The diagnostic command is well-architected, thoroughly tested, and follows project conventions. The writability check fix shows you're responsive to feedback. Once the database timeout issue is addressed, this will be production-ready.

Recommendation: Approve after fixing the database connection race condition.

Re-review: srtd doctor Command

Summary

Excellent progress since the last review! You've successfully addressed several key issues:

✅ Fixed: Writability check cleanup logic (src/utils/doctorChecks.ts:128-158)
✅ Fixed: Replaced process.exit() with process.exitCode (src/commands/doctor.ts:94-96)
✅ Fixed: Added comprehensive E2E tests
✅ Passing: All 528 tests pass, CI is green

What Changed Since Last Review

I reviewed commits 9e88adb through 8bfd7f2 and noticed:

1. Database timeout race condition fix attempt (9e88adb) - You tried to fix the race condition I mentioned by waiting for the connection promise to settle before disposal. Good instinct!

2. Revert of race condition fix (0496080) - You reverted it because it broke CI tests with fake timers. This was the right call - the fix was causing test hangs.

3. Current state - The code relies on DatabaseService.dispose() having its own timeout protection (1000ms), which I verified it does have (src/services/DatabaseService.ts:391-419).

Current Assessment

The implementation is production-ready as-is. Here's why:

The "Race Condition" Is Actually Fine ✅

After deeper analysis, the database connection timeout handling is correct:

Why it's safe:

• DatabaseService.dispose() already has timeout protection (1000ms) at src/services/DatabaseService.ts:404-411
• The pool's end() method is race-safe - it can be called while connections are pending
• The disposed flag prevents double-disposal (line 392-393)
• Error suppression during shutdown prevents crashes (lines 398-416)

The current code:

const result = await Promise.race([connectionPromise, timeoutPromise]);
// ... handle timeout result ...
finally {
  await db.dispose(); // ← This is safe even if connectionPromise is still running
}

This is the correct pattern for this use case. Your instinct to fix it was good, but the revert was the right decision.

Remaining Opportunities (Optional)

These are nice-to-haves, not blockers:

1. Performance: Parallel Check Execution 🟡

Impact: Medium (2-3x speed improvement)
Location: src/utils/doctorChecks.ts:355-375

The checks run sequentially, but most are independent I/O operations. Consider this hybrid approach:

export async function runAllChecks(
  projectRoot: string,
  config: CLIConfig,
  warnings: ValidationWarning[]
): Promise<DoctorCheckResult[]> {
  // Phase 1: Quick filesystem checks (parallel)
  const [
    configExistsResult,
    configSchemaResult,
    templateExistsResult,
    migrationExistsResult,
  ] = await Promise.all([
    checkConfigExists(projectRoot),
    checkConfigSchemaValid(warnings),
    checkTemplateDirExists(projectRoot, config),
    checkMigrationDirExists(projectRoot, config),
  ]);

  // Phase 2: Permission checks (parallel)
  const [templateReadableResult, migrationWritableResult] = await Promise.all([
    checkTemplateDirReadable(projectRoot, config),
    checkMigrationDirWritable(projectRoot, config),
  ]);

  // Phase 3: Everything else (parallel)
  const [buildLogResult, localBuildLogResult, dbResult, templateCountResult] = await Promise.all([
    checkBuildLogValid(projectRoot, config),
    checkLocalBuildLogValid(projectRoot, config),
    checkDatabaseConnection(config),
    checkTemplateCount(projectRoot, config),
  ]);

  // Return in display order
  return [
    configExistsResult,
    configSchemaResult,
    templateExistsResult,
    migrationExistsResult,
    templateReadableResult,
    migrationWritableResult,
    buildLogResult,
    localBuildLogResult,
    dbResult,
    templateCountResult,
  ];
}

Why this approach:

• Maintains logical grouping and display order
• ~3x faster execution (most checks complete in <50ms, DB check takes 100-5000ms)
• Still safe - no dependencies between phases

2. Error Context: Template Count Check 🟢

Impact: Low (better debugging)
Location: src/utils/doctorChecks.ts:342-348

Currently swallows the error:

} catch {  // ← Error details lost
  return {
    name: 'Template count',
    passed: false,
    message: `Cannot read template directory: ${config.templateDir}`,

Suggestion:

} catch (error) {
  const errorMsg = error instanceof Error ? error.message : 'Unknown error';
  return {
    name: 'Template count',
    passed: false,
    message: `Cannot read template directory: ${errorMsg}`,
    hint: 'Check directory permissions or ensure it exists',
  };
}

This helps users diagnose issues like "EACCES: permission denied" vs "ENOENT: no such file".

Code Quality Assessment

✅ Strengths

1. Pure, testable functions - Each check is isolated and mockable
2. Comprehensive test coverage - 29 unit tests + 4 E2E tests covering all scenarios
3. Excellent UX - Clear output, helpful hints, proper exit codes
4. Project consistency - Follows Biome style, uses existing patterns
5. Good error handling - Graceful degradation, no crashes
6. Smart cleanup logic - Writability check properly separates write success from cleanup

📊 Test Quality

• Unit tests: 29 tests covering all 10 checks with pass/fail scenarios
• E2E tests: Actual CLI execution verification
• Edge cases: Timeouts, missing files, cleanup failures all tested
• Coverage: 68.78% patch coverage (missing lines are presentation logic in doctor.ts)

The low patch coverage in doctor.ts is acceptable - it's mostly rendering code that's covered by E2E tests.

Final Verdict

Status: ✅ APPROVED - Ready to Merge

This PR delivers a valuable diagnostic tool that will help users troubleshoot setup issues. The code is well-tested, follows project conventions, and handles edge cases gracefully.

What you did well:

• Listened to bot feedback and fixed the writability check properly
• Replaced process.exit() with process.exitCode for testability
• Attempted to fix the race condition, but correctly reverted when tests broke
• Added comprehensive E2E tests with good documentation

Optional improvements for follow-up:

1. Parallel check execution for better performance
2. Better error messages in template count check

But these are not blockers - the current implementation is solid.
