Worked on the microsoft/git repository to enhance the reliability of patch application workflows by improving how git apply --intent-to-add interacts with the index. Focused on ensuring the index is read before any modifications, the changes refined patch application logic so that only new-file intents update the index, reducing the risk of unintended deletions. Added regression tests in Shell and C to cover complex scenarios and updated documentation written in adoc to clarify behavior and edge cases when using --intent-to-add with --index or --cached. This work strengthened patch application reliability and improved developer workflows for command-line tools and Git internals.
In July 2025, delivered critical index-handling improvements for git apply --intent-to-add in microsoft/git, enhancing reliability when applying patches that create new files. Key changes include reading the index before performing modifications, updating only the index entries for new-file intents, and adding regression tests (t4140) to cover complex interactions. Documentation was updated to clarify behavior when using --intent-to-add with --index or --cached. The work reduces risk of unintended deletions, improves developer workflows, and strengthens overall patch-application reliability.
