PROFILE
Stephan Bergmann
Stephan Bergmann contributed to both the emscripten-core/emscripten and CollaboraOnline/online repositories, focusing on stability and compatibility in WebAssembly toolchains. He addressed a regression in thread callback handling by refactoring emscripten_run_callback_on_thread to use asynchronous proxying and implementing memory cleanup, improving reliability for multithreaded C++ code in Emscripten. In CollaboraOnline/online, Stephan stabilized the COWASM build path, resolved linker and 64-bit operation issues, and enhanced EMSDK compatibility by updating build processes and documentation. His work integrated Embind JS export support and manual UNO initialization, leveraging C++, JavaScript, and build automation to improve runtime stability and deployment readiness.

Nov 1, 2024November 2024 monthly summary focusing on features delivered, bugs fixed, and overall impact for the emscripten-core/emscripten project. The standout delivery was a regression fix for emscripten_run_callback_on_thread, switching from synchronous to asynchronous proxying and adding memory cleanup to free callback arguments after execution. This improves reliability and safety of multi-threaded callbacks in the WebAssembly toolchain.
