Andrius Bentkus developed a stack resource visibility feature for the emscripten-core/emscripten repository, focusing on enhancing runtime diagnostics 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. This addition addressed the need for improved resource management by allowing applications to query stack constraints at runtime. Andrius also created a dedicated unit test to verify correct stack limit retrieval, ensuring reliability. His work demonstrated a solid understanding of C programming, system calls, and WebAssembly integration, delivering a focused and well-tested engineering solution.
