π Major Features:
β’ 5-stage Docker build system with parallel execution optimization
β’ Python-based component architecture for dynamic dependency management
β’ Independent cache namespaces for true parallel stage execution
β’ Comprehensive test infrastructure with multi-configuration validation
β’ 2-stage image expand operation for compressed release image to reduce download pain
β‘ Performance Optimizations:
β’ Inter-stage parallelism: toolchain-builder & dependencies-downloader run concurrently
β’ Intra-stage parallelism: aria2c multi-connection downloads, batch APT processing
β’ Cache independence: separate cache IDs (toolchain-builder-, dependencies-downloader-, packed-image-*)
β’ Build test matrix: automated testing across debug/release/optimized configurations
π οΈ Technical Infrastructure:
β’ Component-based build system with versioned directory structure
β’ ParallelTaskScheduler with topological dependency resolution
β’ Automated toolchain construction (glibc, gcc, llvm, linux headers)
β’ Comprehensive release package creation with manifest generation
π¦ Container Architecture:
β’ base-python-environment β toolchain-builder/dependencies-downloader β image-packer β packed-image β expanded-image
β’ Dynamic Python version management via config files
β’ Static-linked libstdc++ support for glibc compatibility
β’ Professional test script with configuration matrix validation
β¨ Developer Experience:
β’ Multi-compiler support (gcc/clang) with version management
β’ Automated environment setup and dependency resolution
β’ Comprehensive documentation in both English and Chinese
β’ Advanced caching strategies for offline capability
This implements a production-ready development container system that maximizes build performance through parallel execution, provides comprehensive toolchain support, and delivers excellent developer experience with minimal setup.
