Jan 1, 2025January 2025 monthly summary for visit-dav/visit. Key focus: strengthen build reliability for keyboard/input libraries and ensure test suite alignment with latest commits. Key outcomes: - Feature delivered: Build system enhancement to add xkbcommon and xcb library support to build_visit. This includes updating CMakeLists.txt to install these libraries and introducing new shell scripts to orchestrate builds for meson, ninja, xcb, and xkbcommon, ensuring dependency handling is correct across environments. (Commit: 91c0696b57c1729bd9db0fbbd37bfe500b42fd25) - Bug fix: Test suite reference updates for LastPass poodle tests to track latest commits, correcting pass identifiers and ensuring CI reports reflect the proper commit set. This involved updating references across 20+ commits. (Examples: f99e2a80a30fef3ccbb52e75c7b8de524f056379, 80e1df4751c8bcbc5ca1350ff74cf0b456e9c620, 90c14003774f314d2ee1faf0a954ffc5836b88fa, d961fc7e1adb24cde742d5f9d52db5a82fda3d8b, ...) - Automation and maintainability: Added shell-based build orchestration scripts to streamline the integration of xkbdep/related libraries and to simplify future dependency additions, reducing manual steps in the build pipeline. Overall impact: The month delivered tangible business value by reducing build friction for key keyboard/input dependencies, increasing CI reliability, and improving traceability of changes. These efforts position the project to accelerate feature work around input handling while maintaining robust, auditable build and test pipelines. Technologies/skills demonstrated: CMake, shell scripting, Meson/Ninja build workflows, cross-language dependency management, test-suite maintenance, and addition of automation to the build process.
