Dynamic Resource Optimization

The Dynamic Resource Optimization system is the core feature that makes CPSIT Quality Tools "just work" on projects of any size without manual configuration. This guide explains how the optimization works and how to customize it when needed.

Overview

Every command automatically analyzes your project and optimizes memory limits, processing strategies, and performance settings. This eliminates common issues like memory exhaustion on large projects and provides significant performance improvements.

Key Benefits:

  • Zero Configuration Required: All optimization happens automatically
  • 50%+ Performance Improvement: On large projects through smart optimization
  • Memory Issue Resolution: Eliminates PHPStan and PHP CS Fixer memory exhaustion
  • Smart Path Scoping: Focuses analysis on relevant code (defaults to /packages directory)
  • Consistent Experience: All tools use the same optimization strategy

How It Works

Project Analysis

Every command starts by analyzing your project:

$ vendor/bin/qt lint:phpstan
Project Analysis: Analyzing TYPO3 project structure...
Project Analysis: Found 1,001 files (174 PHP files) in /packages
Optimization: Setting PHPStan memory limit to 552M for medium project
Optimization: Enabling parallel processing for improved performance

The system analyzes:

  • File Count: Total files and files per type (PHP, YAML, JSON, XML)
  • Project Size: Small (<100 files), Medium (100-1000), Large (1000-5000), Enterprise (>5000)
  • Code Complexity: Lines of code, complexity metrics
  • Project Type: TYPO3 vs generic PHP project detection

Memory Optimization

Memory limits are calculated dynamically based on project characteristics:

Project Size File Range PHPStan Memory PHP CS Fixer Memory Rector Memory
Small < 100 files 256M 256M 384M
Medium 100-1000 files 552M 460M 690M
Large 1000-5000 files 1024M 768M 1200M
Enterprise > 5000 files 2048M 1536M 2048M

Memory Calculation Algorithm:

  • Base memory: 128MB
  • PHP files: 0.5MB per file + complexity factor
  • Other files: 0.1MB per file
  • Tool-specific multipliers applied
  • Reasonable limits: 256MB minimum, 2GB maximum

Performance Optimization

For larger projects, additional optimizations are automatically enabled:

Parallel Processing:

  • Enabled automatically for projects with 500+ files
  • Improves processing speed by 40-60%
  • Uses optimal core count detection

Caching:

  • Automatic cache enablement for supported tools
  • Significantly speeds up repeated runs
  • Cache files stored in system temp directory

Path Scoping:

  • TYPO3 projects default to analyzing /packages directory only
  • Avoids analyzing vendor code (reduces from 48K+ to 1K files typically)
  • Custom paths can be specified with --path option

Optimization Examples

Small Project Example

Project Analysis: Analyzing TYPO3 project structure...
Project Analysis: Found 45 files (12 PHP files) in /packages
Optimization: Setting PHPStan memory limit to 256M for small project
Optimization: Standard processing mode selected
Performance: Analysis completed in 8.2 seconds

Medium Project Example

Project Analysis: Analyzing TYPO3 project structure...
Project Analysis: Found 1,001 files (174 PHP files) in /packages
Optimization: Setting PHPStan memory limit to 552M for medium project
Optimization: Enabling parallel processing for improved performance
Performance: Analysis completed in 45.3 seconds (estimated 89s without optimization)

Large Project Example

Project Analysis: Analyzing TYPO3 project structure...
Project Analysis: Found 2,847 files (423 PHP files) in /packages
Optimization: Setting Rector memory limit to 1200M for large project
Optimization: Enabling parallel processing and caching for performance
Optimization: Using chunked processing for memory efficiency
Performance: Processing completed in 3m 12s (estimated 6m 45s without optimization)

Manual Override Options

While optimization works automatically, advanced users can override settings:

Disable Optimization

# Disable all automatic optimization
vendor/bin/qt lint:phpstan --no-optimization

# Use tool defaults instead of calculated values
vendor/bin/qt fix:rector --no-optimization

View Optimization Decisions

Optimization details are shown by default for all commands:

# Optimization details are shown automatically
vendor/bin/qt lint:phpstan

# Example output:
# Project Analysis: Project size: MEDIUM (1,001 files)
# Project Analysis: PHP files: 174, Complexity score: 3.2
# Memory Calculation: Base 128M + PHP factor 87M + complexity 32M = 247M
# Memory Calculation: Applied PHPStan multiplier 2.24x = 552M
# Performance: Parallel processing enabled (8 cores detected)
# Performance: Caching enabled for repeated runs

Manual Memory Limits

# Override automatic memory calculation
vendor/bin/qt lint:phpstan --memory-limit=1024M

# Override with custom level
vendor/bin/qt lint:phpstan --level=8 --memory-limit=1536M

Custom Paths

# Analyze specific path instead of automatic /packages detection
vendor/bin/qt lint:phpstan --path=./custom/extension

# Analyze entire project (not recommended for large projects)
vendor/bin/qt lint:phpstan --path=.

Optimization Diagnostics

Performance Metrics

All commands show performance information:

Performance: Analysis completed in 45.3 seconds
Performance: Memory peak usage: 387M / 552M allocated
Performance: Files processed: 1,001 (174 PHP files analyzed)
Performance: Optimization saved estimated 43.7 seconds

Memory Usage Monitoring

Memory Usage: Peak 387M / 552M allocated (70% utilization)
Memory Usage: Optimization prevented memory exhaustion
Memory Usage: Without optimization: estimated 650M+ required

File Analysis Details

Project Analysis: File type breakdown:
  - PHP files: 174 (primary analysis target)
  - TypoScript files: 67 (configuration files)
  - YAML files: 89 (configuration files)
  - JSON files: 23 (composer, package files)
  - Other files: 648 (templates, assets, etc.)

Advanced Configuration

Environment Variables

Control optimization behavior globally:

# Disable optimization for all commands
export QT_NO_OPTIMIZATION=1

# Set global memory multiplier
export QT_MEMORY_MULTIPLIER=1.5

# Set minimum memory limit
export QT_MIN_MEMORY=512M

Configuration Files

For project-wide settings, create .qt-config.yaml:

optimization:
  enabled: true
  memory:
    phpstan_multiplier: 2.5
    php_cs_fixer_multiplier: 1.8
    rector_multiplier: 3.0
  performance:
    parallel_threshold: 300
    cache_enabled: true
  paths:
    typo3_default: "packages"
    analysis_depth: 10

Troubleshooting Optimization

Common Issues

Memory Still Insufficient:

# If automatic calculation is too low, override manually
vendor/bin/qt lint:phpstan --memory-limit=2048M

# Or disable optimization and use tool defaults
vendor/bin/qt lint:phpstan --no-optimization

Performance Slower Than Expected:

# Optimization details are shown by default, check the output
vendor/bin/qt lint:phpstan

# Verify path scoping is working
# Should show "Found X files in /packages" not entire project

Optimization Not Working:

# Check project detection (details shown by default)
vendor/bin/qt lint:phpstan

# Verify TYPO3 project detection:
# Should show "TYPO3 project detected" in analysis output

Debug Mode

# Enable debug output for detailed optimization information
vendor/bin/qt lint:phpstan --debug

# Shows:
# - Project detection logic
# - File counting process
# - Memory calculation steps
# - Performance optimization decisions

Technical Implementation

Project Analysis Algorithm

  1. Project Root Detection: Traverse up to find TYPO3 composer.json
  2. File System Analysis: Count files by type using RecursiveDirectoryIterator
  3. Complexity Analysis: Calculate code metrics for PHP files
  4. Size Classification: Categorize project as Small/Medium/Large/Enterprise
  5. Optimization Selection: Apply appropriate optimization profile

Memory Calculation Formula

memory = base_memory + (php_files * 0.5MB) + (complexity_factor * 0.1MB) + (other_files * 0.1MB)
final_memory = min(max(memory * tool_multiplier, 256MB), 2048MB)

Tool-Specific Multipliers

  • PHPStan: 2.24x (AST analysis is memory intensive)
  • PHP CS Fixer: 1.8x (token analysis requires significant memory)
  • Rector: 3.0x (code transformation requires most memory)
  • Fractor: 2.0x (TypoScript parsing and transformation)

Performance Benchmarks

Real-world performance improvements with optimization enabled:

Project Size Files Without Optimization With Optimization Improvement
Small 45 12.3s 8.2s 33%
Medium 1,001 89.4s 45.3s 49%
Large 2,847 6m 45s 3m 12s 53%
Enterprise 8,234 Memory Error 8m 34s Previously Impossible

Future Enhancements

Planned optimization improvements:

  • Machine Learning Optimization: Learn from project patterns to improve predictions
  • CI/CD Integration: Optimize specifically for build environments
  • Tool Chain Optimization: Optimize across multiple tool runs
  • Memory Profiling: Real-time memory usage optimization
  • Custom Optimization Profiles: Save and share optimization configurations

The Dynamic Resource Optimization system represents a major quality-of-life improvement, ensuring that quality tools "just work" regardless of project size while providing significant performance benefits.
