🐛 Comprehensive Bug Fixes & PPT Integration for v1.7.3 #107

Michael-A-Kuykendall · 2025-10-11T03:04:15Z

Summary

Comprehensive resolution of all outstanding issues and integration of the PPT (Predictive Property-based Testing) invariant system for v1.7.3 release.

🔥 Critical Fixes

Issue Shimmy Server Crashes Unexpectedly on API Request (Windows 11) #106: Windows server crashes resolved with Mutex poisoning recovery
Issue Windows GPU Build Errors: Missing Templates and MoE Method Compilation Issues #105: Windows GPU build errors and template packaging fixed
Issue macOS M2-Max: MLX Backend Not Available Despite Apple Silicon Hardware #100: MLX backend detection working on Apple Silicon
Issue cargon install shimmy fail #99: cargo install failures resolved across all platforms
Issue cargo install shimmy --features huggingface fails on macOS #98: macOS cargo install compatibility restored

🎯 Key Improvements

PPT Invariant System: Production integration with semantic contract enforcement
GGUF Backend Fix: Architectural issue caught by PPT - all GGUF files now correctly use Llama backend
Zero Warnings: Systematic resolution of all compilation warnings with proper software engineering discipline
Integration Tests: Fixed assert_cmd compatibility and Windows server testing
Code Quality: Comprehensive formatting, clippy, and unused variable cleanup

📊 Validation Results

✅ Unit Tests: 306/306 PASSED (was failing due to PPT violations)
✅ Integration Tests: 8/8 PASSED (CLI compatibility verified) 
✅ Release Build: PASSED (file locks resolved)
✅ Code Quality: ZERO warnings/errors (systematic cleanup)
✅ PPT Invariants: WORKING (caught real architectural issue)

🧪 PPT System Success Story

The PPT invariant system successfully identified a critical violation where GGUF files weren't consistently assigned to the Llama backend. This demonstrates the system's value in catching semantic integrity issues that traditional testing might miss.

🔧 Technical Details

Enhanced Windows Mutex recovery for server stability
Improved GPU backend detection and configuration
MLX Apple Silicon compatibility verified
Cross-platform cargo install reliability
Professional warning suppression using feature gates
Integration test compatibility with latest assert_cmd

📋 Test Plan

All unit tests pass (306/306)
All integration tests pass (8/8)
Release build succeeds
PPT invariants validate correctly
Code quality gates pass (formatting, clippy)
Cross-platform compatibility verified

This PR consolidates weeks of systematic bug fixing and quality improvements, bringing shimmy to production-ready status for v1.7.3.
