Worked on the moby/buildkit repository to enhance data integrity and reliability in blob handling workflows. Addressed a bug in the getAvailableBlobs function by introducing a guard using Go’s slices.ContainsFunc, which prevented duplicate blob descriptors from being appended to the descriptor list. This targeted fix improved the accuracy of blob accounting and stabilized cache flows, reducing the risk of incorrect blob tracking in downstream build processes. Demonstrated skills in Go development, defensive programming, and software engineering best practices by delivering a maintainable solution with minimal code changes, ensuring more reliable blob listing and improved stability for buildkit’s caching mechanisms.
