I find the problem is that when we use 'git apply —intent-to-add’, git doesn’t read index file then update the intent-to-add cache entry, git forgot to read the index file and only update one intent-to-add cache entry in index file. > This patch series fixes it to work as expected and updates the tests > and documentation for this flag. I think [PATCH 2/5] actually solve the problem. [PATCH 3/5] makes 'git apply' consistent with 'git add', which means git add —intent-to-add exist-in-index-file.c and git apply —intent-to-add patch-contains-exist-in-index-file will ignore intent-to-add and do nothing.
