Configuration Reference

---

1. Overview

Doctrine Doctor uses Symfony’s configuration system. All configuration is placed in YAML files under config/packages/.

1.1 Configuration Locations

config/
├── packages/
│   ├── dev/
│   │   └── doctrine_doctor.yaml         # Development-specific
│   └── doctrine_doctor.yaml              # All environments

1.2 Configuration Precedence

Environment-specific (config/packages/dev/)
    ↓ overrides
Global (config/packages/)
    ↓ overrides
Bundle defaults (DependencyInjection/Configuration.php)

2. Configuration Structure

2.1 Complete Configuration Tree

doctrine_doctor:
    # Master switch
    enabled: true|false

    analysis:
        exclude_third_party_entities: true|false
        exclude_paths: ['vendor/', 'var/cache/']

    # Profiler integration settings
    profiler:
        show_in_toolbar: true|false
        show_debug_info: true|false

    debug:
        enabled: true|false
        internal_logging: true|false

    # Individual analyzer settings
    analyzers:
        analyzer_name:
            enabled: true|false
            # Analyzer-specific parameters
            threshold: <value>
            # ... additional parameters

2.2 Default Values

When no configuration file exists, Doctrine Doctor uses these defaults:

doctrine_doctor:
    enabled: true

    analysis:
        exclude_third_party_entities: true
        exclude_paths: ['vendor/']

    profiler:
        show_in_toolbar: true
        show_debug_info: false

    debug:
        enabled: false
        internal_logging: false

    analyzers:
        # Performance
        n_plus_one:
            enabled: true
            threshold: 5

        slow_query:
            enabled: true
            threshold: 100  # milliseconds

        missing_index:
            enabled: true
            slow_query_threshold: 50
            min_rows_scanned: 1000
            explain_queries: true

        # ... (see section 5 for complete list)

---

3. Global Settings

3.1 Master Enable/Disable

doctrine_doctor:
    enabled: true

Type: boolean Default: true Description: Global switch for the entire bundle. When false, all analyzers are disabled and the profiler panel is hidden.

Use Cases:

• Temporarily disable during debugging sessions
• Environment-specific deactivation (e.g., in staging)

Example:

# config/packages/prod/doctrine_doctor.yaml
doctrine_doctor:
    enabled: false  # Disable in production

---

4. Analysis Configuration

4.1 Excluding Vendor Entities

doctrine_doctor:
    analysis:
        exclude_third_party_entities: true

Type: boolean Default: true Description: Automatically excludes entities from the vendor/ directory during analysis. This filters out third-party entities from Symfony, Doctrine, FOSUserBundle, and other vendor bundles to provide cleaner, more relevant reports focused on your application code.

How it works:

• Uses path-based detection (/vendor/ in file path) - 100% reliable
• Filtering is completely transparent - no changes needed in your code
• Results are cached per request for optimal performance (~0.1ms overhead)

Example: With this enabled (recommended), entities like Symfony\Component\Security\Core\User\User or FOS\UserBundle\Model\User will be excluded from analysis, while your App\Entity\User will be analyzed normally.

When to disable: Only disable if you need to analyze vendor entity mappings or debug third-party bundle configurations.

4.2 Excluding Query Origins by Path

doctrine_doctor:
    analysis:
        exclude_paths: ['vendor/', 'var/cache/']

Type: array<string> Default: ['vendor/'] Description: Excludes DBAL queries whose origin path contains one of these fragments.

---

5. Profiler Configuration

5.1 Profiler Visibility

doctrine_doctor:
    profiler:
        show_in_toolbar: true

Type: boolean Default: true Description: Controls whether the “Doctrine Doctor” panel appears in the Symfony Profiler toolbar.

5.2 Debug Information

doctrine_doctor:
    profiler:
        show_debug_info: false

Type: boolean Default: false Description: Displays internal debugging information (analyzer execution times, memory usage, service instances). For development of Doctrine Doctor itself only.

5.3 Internal Debug Mode

doctrine_doctor:
    debug:
        enabled: false
        internal_logging: false

Type: boolean Defaults: false Description:

• debug.enabled: Enables contributor-oriented debug behavior.
• debug.internal_logging: Enables internal analyzer logs (can add noticeable overhead).

5.4 Enabling Query Backtraces

To see code location backtraces in Doctrine Doctor issues, enable Doctrine DBAL’s backtrace collection:

# config/packages/dev/doctrine.yaml
doctrine:
    dbal:
        profiling_collect_backtrace: true

Type: boolean Default: false Description: Enables collection of stack traces for SQL queries, allowing Doctrine Doctor to show exactly where in your code each issue originates.

Note: This is a Doctrine DBAL setting, not a Doctrine Doctor configuration. Add it to your doctrine.yaml file. Recommended for development environments only (minimal performance overhead ~2-5%).

6. Analyzer Configuration

6.1 Performance Analyzers

N+1 Query Analyzer

doctrine_doctor:
    analyzers:
        n_plus_one:
            enabled: true
            threshold: 5

Parameter	Type	Default	Description
enabled	boolean	true	Enable/disable analyzer
threshold	integer	5	Minimum duplicate query occurrences to trigger detection

Tuning Guide:

• Strict: threshold: 2 - Catch even minor N+1 issues
• Balanced: threshold: 5 - Default, good signal-to-noise ratio
• Permissive: threshold: 10 - Only major N+1 problems

---

Slow Query Analyzer

doctrine_doctor:
    analyzers:
        slow_query:
            enabled: true
            threshold: 100

Parameter	Type	Default	Description
enabled	boolean	true	Enable/disable analyzer
threshold	integer	100	Execution time threshold in milliseconds

Tuning by Environment:

# Local development (fast SSD)
threshold: 20

# Shared development server
threshold: 50

# Staging (production-like hardware)
threshold: 100

---

Missing Index Analyzer

doctrine_doctor:
    analyzers:
        missing_index:
            enabled: true
            slow_query_threshold: 100
            min_rows_scanned: 1000
            explain_queries: true

Parameter	Type	Default	Description
enabled	boolean	true	Enable/disable analyzer
slow_query_threshold	integer	100	Minimum execution time (ms) to trigger EXPLAIN analysis
min_rows_scanned	integer	1000	Minimum rows scanned to recommend index

Database Permission Requirements:

-- MySQL: Ensure user can execute EXPLAIN
GRANT SELECT ON database.* TO 'app_user'@'localhost';

-- PostgreSQL: EXPLAIN requires SELECT permission
-- No additional permissions needed

Performance Considerations:

• explain_queries: false - Disable if database user lacks permissions or for performance
• Higher min_rows_scanned reduces false positives on small tables

---

Security Best Practice: Keep all security analyzers enabled at all times.

---

5.3 Integrity Analyzers

Integrity analyzers typically have no configurable parameters beyond enabled:

7. Performance Thresholds

7.1 Recommended Thresholds by Environment

Local Development

doctrine_doctor:
    analyzers:
        slow_query:
            threshold: 10  # Fast local database
        n_plus_one:
            threshold: 2   # Strict detection
        missing_index:
            min_rows_scanned: 500  # Detect early

Shared Development Server

doctrine_doctor:
    analyzers:
        slow_query:
            threshold: 50
        n_plus_one:
            threshold: 3
        missing_index:
            min_rows_scanned: 1000

Staging (Production-like)

doctrine_doctor:
    analyzers:
        slow_query:
            threshold: 100
        n_plus_one:
            threshold: 5  # Reduce noise
        missing_index:
            min_rows_scanned: 5000  # Production-scale data

---

8. Group Management

⚠️ Note: Group-based configuration (groups: node) is not yet implemented.

To enable/disable specific analyzers, use individual analyzer configuration:

doctrine_doctor:
    analyzers:
        n_plus_one:
            enabled: false  # Disable specific analyzer
        slow_query:
            enabled: true   # Keep enabled

This feature is planned for a future release to allow bulk enable/disable by category.

---

9. Environment-Specific Configuration

9.1 Development Configuration

# config/packages/dev/doctrine_doctor.yaml
doctrine_doctor:
    enabled: true

    profiler:
        show_in_toolbar: true
        show_debug_info: true  # Show analyzer performance metrics

    analyzers:
        n_plus_one:
            threshold: 2  # Strict

        slow_query:
            threshold: 20  # Fast local DB

        missing_index:
            explain_queries: true

9.2 Test Configuration

# config/packages/test/doctrine_doctor.yaml
doctrine_doctor:
    enabled: false  # Disable to avoid test overhead

9.3 Production Configuration

# config/packages/prod/doctrine_doctor.yaml
doctrine_doctor:
    enabled: false  # MUST be disabled in production

Critical: Doctrine Doctor should NEVER run in production. The bundle is excluded from production via:

• composer require --dev
• Explicit enabled: false in prod configuration

---

10. Advanced Configuration

10.1 Custom Analyzer Registration

# config/services.yaml
services:
    App\Analyzer\CustomBusinessRuleAnalyzer:
        arguments:
            $threshold: 50
            $templateRenderer: '@AhmedBhs\DoctrineDoctor\Template\Renderer\TemplateRendererInterface'
        tags:
            - { name: 'doctrine_doctor.analyzer' }

10.2 Custom Template Renderer

services:
    App\Infrastructure\MarkdownTemplateRenderer:
        arguments:
            $templateDirectory: '%kernel.project_dir%/templates/doctrine_doctor'

    # Override default renderer
    AhmedBhs\DoctrineDoctor\Template\Renderer\TemplateRendererInterface:
        alias: App\Infrastructure\MarkdownTemplateRenderer

10.3 Service Decoration

services:
    App\Decorator\EnhancedIssueFactory:
        decorates: AhmedBhs\DoctrineDoctor\Factory\IssueFactoryInterface
        arguments:
            $inner: '@.inner'
            $logger: '@logger'

10.4 Conditional Configuration via Environment Variables

# config/packages/doctrine_doctor.yaml
doctrine_doctor:
    enabled: '%env(bool:DOCTRINE_DOCTOR_ENABLED)%'

    analyzers:
        slow_query:
            threshold: '%env(int:SLOW_QUERY_THRESHOLD)%'

# .env.local
DOCTRINE_DOCTOR_ENABLED=true
SLOW_QUERY_THRESHOLD=30
