Worked on the semaphoreui/semaphore repository to improve the reliability of Galaxy requirements installation by refining change-detection logic. Addressed a bug where MD5 hash tracking previously conflated collections and roles, which could cause installations to be skipped when only one type changed. Introduced per-type MD5 tracking, ensuring that changes to either collections or roles are detected independently and both are installed as needed. This backend development effort leveraged Go and DevOps practices to enhance accuracy and maintainability in dependency management. The solution was documented and committed, providing a more robust process for handling Galaxy requirements in the project’s deployment workflow.
