phicode 2.6.0

(φ) Phicode Runtime Engine — Optimized for stability under load (CPython/PyPy Supported)

Python execution engine with daemons, caching and import extensions

Overview

Phicode Engine executes Python modules through an optimized runtime featuring robust and self-healing caching mechanisms, automatic interpreter optimization, and modified import system. It supports standard Python with optional custom syntax transpilation. The integrated Phiemon daemon system provides production-ready process management with crash recovery and multi-daemon support.

Project Philosophy

"I believe in architectural minimalism with deterministic reliability - every line of code must earn its place through measurable value, not feature-rich design patterns. I build systems that work predictably in production, not demonstrations of architectural sophistication. My approach is surgical: target the exact problem with minimal code, reuse existing components rather than building new ones, and resist feature bloat by consistently asking whether each addition truly serves the core purpose." - Jay Baleine

phicode my_script --debug      # With debug logging  
phicode large_app --pypy       # Use PyPy interpreter

Multi-Level Caching

Four distinct cache layers with automatic invalidation:

• Source Cache: Raw file contents with LRU eviction
• Python Cache: Processed code keyed by content hash
• Spec Cache: Import specifications with modification tracking
• Bytecode Cache: Compiled code with integrity validation

HTTP API Server

JSON endpoints for remote execution:

curl -X POST http://localhost:8000/execute \
  -H "Content-Type: application/json" \
  -d '{"code": "print(\"hello\")"}'

Security Integration

Integration with Phimmuno and PhiRust components for threat detection using pattern matching algorithms.

Custom Syntax Support (Optional)

The engine supports custom symbol mappings through .φ files. This feature is completely optional - the engine works with standard Python by default.

Architecture

Core Components:

• core.importing: MetaPathFinder and Loader implementations
• core.transpilation: Text transformation using regex patterns
• core.cache: Multi-level caching with LRU eviction
• core.runtime: Module execution and cleanup
• core.interpreter: Command-line interface and interpreter selection

Additional Components:

Configuration

Environment Variables

Runtime Settings:

• PHICODE_CACHE_SIZE: LRU cache entry limits (default 512)
• PHICODE_MMAP_THRESHOLD: Memory-mapping file size threshold (default 8192)
• PHICODE_BATCH_SIZE: Bytecode write batch size (default 5)
• RUST_SIZE_THRESHOLD: Rust component activation threshold (default 300KB)

Interpreter Selection:

• PHITON_PATH: Custom CPython executable path
• PHIPY_PATH: Custom PyPy executable path (default pypy3)

Import System Integration

The system inserts itself at position 0 in Python's sys.meta_path:

PhicodeFinder: Intercepts import statements, resolves files, maintains path cache
PhicodeLoader: Reads source files, processes content, compiles bytecode, executes modules

Performance Testing

Run the benchmark suite:

phicode --benchmark              # Interactive selection
phicode --benchmark --full       # Complete test suite
phicode --benchmark --json       # JSON output format

The benchmark suite measures cache behavior, transpilation speed, and system limits under various conditions.

Phiemon Process Management (Daemon Setup)

Start processes with automatic crash recovery and multi-daemon support:

phicode my_app --phiemon                    # Start as daemon
phicode my_app --phiemon --name myservice   # Custom name
phicode my_app --phiemon --max-restarts 10  # Restart limit
phicode --phiemon-status                    # Check all daemons
phicode --phiemon-status myservice          # Check specific daemon

Phiemon Daemon Features:

• Multi-daemon support with isolated state files per process
• Automatic restart on process crashes with configurable limits
• Exponential backoff prevents resource exhaustion (1s→2s→4s→8s→16s→30s max)
• Per-daemon state persistence through phiemon_{name}.state files
• Process tracking with PID monitoring and crash detection
• Enhanced debugging with detailed error logging and status reporting
• Concurrent execution of multiple services without conflicts

Status Management:

phicode --phiemon-status                    # List all active daemons
phicode --phiemon-status webapp             # Check specific daemon status
phicode --phiemon-list                      # Show daemon overview with uptimes

The daemon wraps standard PhiCode execution, maintaining all security scanning and caching behavior while providing production-ready process management. Each daemon operates independently with its own state tracking and restart logic.

Custom Syntax Support

Phicode Engine supports custom syntax through configurable symbol mappings. This feature is completely optional - the engine works with standard Python.

Setup

Generate configuration file:

phicode --config-generate

Creates .(φ)/config.json with customizable mappings:

{
  "file_extension": ".φ",
  "symbols": {
    "def": "ƒ",
    "class": "ℂ", 
    "print": "π",
    "return": "⟲"
  }
}

Usage Example

Create example.φ with custom syntax:

ƒ factorial(n):
    ¿ n <= 1:
        ⟲ 1
    ⋄:
        ⟲ n * factorial(n-1)

π(factorial(5))

Execute normally:

phicode example

Default Symbol Mappings

Available default symbols for customization:

Control Flow

• ¿ → if, ⤷ → elif, ⋄ → else
• ∀ → for, ↻ → while
• ⇲ → break, ⇉ → continue

Functions & Classes

• ƒ → def, ℂ → class
• ⟳ → async, ⌛ → await, λ → lambda

Logic & Comparison

• ∧ → and, ∨ → or, ¬ → not
• ∈ → in, ≡ → is

Constants & Returns

• ✓ → True, ⊥ → False, Ø → None
• ⟲ → return, ⟰ → yield, ⋯ → pass

Built-in Functions

• π → print, ℓ → len
• ⟪ → range, № → enumerate

You can add or remove mappings as pleased

Configuration Management

File Locations (Priority Order)

1. .(φ)/config.json - Project root
2. .phicode/config.json - Broader compatibility
3. Environment variables - Runtime parameters
4. Built-in defaults - Default symbol set

Validation Settings

• Conflict detection prevents overriding built-ins
• Python identifier validation for custom keywords
• Integration with security validation when available
• Configurable strict vs permissive modes

Configuration Commands

phicode --config-generate    # Create initial configuration
phicode --config-reset       # Reset to built-in defaults

Environment Variables

• PHICODE_VALIDATION: Enable symbol validation (default true)
• PHICODE_STRICT: Use strict validation mode (default false)

---

System Requirements

Dependencies: Python 3.8 or later required. Optional components need additional libraries (xxHash, psutil, regex). Security features require Rust toolchain or precompiled binaries.

Limitations

Performance Characteristics:

• Import hook adds measurable startup overhead
• Caching mechanism consumes additional disk space in .φcache/ directories
• Memory-mapped I/O used for files larger than 8KB threshold

Platform Requirements:

• Requires Unicode-capable terminals and fonts for symbol display
• Subprocess execution required for interpreter switching
• Optional binary components depend on Rust toolchain availability

Security Model:

• Security validation depends on optional binary components
• Pattern matching may produce false positives with legitimate code patterns
• Bypass mode disables all protection mechanisms

Troubleshooting

Performance Issues

• Use PyPy for compute-intensive workloads: phicode --pypy
• Check cache directory write permissions
• Monitor system resources during execution

Import Problems

• Verify file paths and extensions
• Confirm import hooks are installed
• Check module dependencies

Configuration Issues

• Reset configuration: phicode --config-reset
• Validate environment variable syntax
• Verify interpreter availability with --list-interpreters

Security Component Issues

• Install components: phicode --security-install
• Skip validation for trusted code: phicode --bypass
• Check status: phicode --security-status

Symbol Configuration Issues

• Check symbol mappings don't conflict with Python syntax
• Verify custom syntax matches configuration
• Ensure terminal supports Unicode characters

File Extension Problems

• Confirm file extension matches configuration setting
• Verify import paths point to correct directories
• Check that custom files exist in configured locations
