Andrius Bentkus developed a stack resource visibility feature for the emscripten-core/emscripten repository, focusing on improving runtime diagnostics and resource management for WebAssembly applications. He implemented the getrlimit system call for RLIMIT_STACK in C, enabling accurate reporting of current and maximum stack limits through Emscripten’s stack utilities. The work included creating a dedicated unit test to verify correct stack limit retrieval, ensuring reliability and correctness of the new capability. By leveraging his skills in C programming, system calls, and WebAssembly, Andrius delivered a targeted, well-tested enhancement that addressed stack resource transparency for developers working with Emscripten-based projects.
