During April 2025, Lukas Gersthofer focused on backend development for the Kitware/CDash repository, addressing a critical issue in the file-attachment download workflow. He identified and resolved a bug where downloading multiple attachments always returned the first file, regardless of user selection. By refining the PHP backend to use the actual file ID from the GET request, Lukas ensured that users receive the correct file, improving reliability and reducing support tickets. His work demonstrated careful debugging and precise request parameter handling, contributing to a more robust attachment system. This targeted fix enhanced the overall user experience without impacting system performance.
