Worked on the vmware/tdnf repository to enhance the stability of the package management subsystem by addressing upgrade behavior for install-only packages. Focused on C programming and package management, the contribution introduced status-aware logic that checks and preserves the install status of install-only packages during upgrades. This approach prevents unintended changes in package state, reducing upgrade drift and improving reliability for enterprise deployments. The solution involved modifying upgrade routines to recognize and maintain installonly flags, ensuring correctness throughout the upgrade path. Python testing was used to validate the changes, resulting in a more predictable and robust package management experience.
