Worked on the canonical/mir repository to enhance Wayland display server stability and improve platform integration. Addressed a startup hang by modifying the initialization process to fall back to the current mode size when a zero-size configuration was received, reducing risk during nested display scenarios. Improved runtime robustness by blocking signals on the display event loop thread, preventing interruptions and unintended teardown. Expanded the public API by moving the SignalBlocker header to common public headers, enabling broader reuse by platform modules. The work leveraged C++ for system programming, focusing on multithreading, signal handling, and library design to streamline display server development.
June 2026 monthly summary for canonical/mir: Delivered critical Wayland display stability improvements and expanded public API exposure. Highlights include fixing an initialization hang in zero-size toplevel_configure by falling back to the current mode size, blocking signals on the display event loop to prevent EINTR and teardown in nested compositor scenarios, and exposing the SignalBlocker header publicly to enable reuse by platform modules. These changes reduce nested display startup risk, improve runtime robustness, and streamline platform integration through a public ABI-compatible API surface.
