PROFILE

Haoxiang Fei

Feihaoxiang contributed to moonbitlang/moon and related repositories by developing configurable WebAssembly shared memory features, enhancing module memory predictability and deployment reliability. They implemented end-to-end tests to ensure compatibility across wasm and wasm-gc builds, using Rust and system programming skills to strengthen test coverage and traceability. In moonbitlang/moonbit-docs, Feihaoxiang created a structured compiler error documentation system and improved MoonBit Go tutorials, applying technical writing and documentation expertise to streamline onboarding and reduce confusion. Additionally, they addressed WASI-specific endianness handling in tree-sitter/tree-sitter using C, improving cross-target build reliability and supporting broader WebAssembly System Interface adoption.

May 1, 2025

May 2025 (2025-05) — Focused on improving portability and correctness for WASI/WebAssembly builds in the tree-sitter repository. Delivered WASI-aware endianness handling in endian.h, ensuring correct endianness behavior when compiling under WebAssembly System Interface. The change reduces cross-target build failures and positions tree-sitter for broader WASI adoption while maintaining compatibility with existing C/C++ tooling.

February 2025: Delivered a structured compiler error documentation system for MoonBit with per-code Markdown docs and an index, improving developer guidance and error resolution time. Fixed file collection to respect IGNORE_DIRS across nested directories, removing the root parameter and ensuring traversal-level ignore behavior for all subdirectories. These changes enhance developer onboarding, reduce debugging time, and improve build reliability across MoonBit repositories.

Dec 1, 2024

December 2024 monthly summary for moonbitlang/moon. Focused on delivering configurable WebAssembly memory features with robust testing, and laying groundwork for stronger memory isolation and predictable module behavior. 1) Key features delivered: - WebAssembly Shared Memory Configuration: Introduced configurable memory limits and shared memory status for WebAssembly modules, enabling explicit control over memory imports and sharing behavior. - End-to-end tests: Added tests verifying shared memory imports across both wasm and wasm-gc builds to ensure cross-build compatibility and reliability. 2) Major bugs fixed: - No major bugs recorded this period. 3) Overall impact and accomplishments: - Enabled more predictable WebAssembly module memory usage, reducing runtime memory surprises and improving deployment confidence. - Strengthened test coverage and traceability, accelerating future memory-sharing enhancements. 4) Technologies/skills demonstrated: - WebAssembly memory model and sharing concepts - Feature flag/configuration design and implementation - End-to-end testing across multiple builds (wasm and wasm-gc) - Commit-based traceability and change management
