Hi Junio
Thank you for your question, it has prompted me to consider the matter
further =) I think both solutions, using git diff-files --stat and using git
update-index --refresh before git diff-files, can produce the same output but
in different ways.
When the index file is not up-to-date, git diff-files may show differences
between the working directory and the index that are caused by file creation
time differences, rather than actual changes to the file contents. By using git
diff-files --stat, which ignores file creation time differences.
While 'git update-index --refresh' updates the index file to match the contents
of the working tree. By running this command before git diff-files, we can
ensure that the index file is up-to-date and that the output of git diff-files
accurately reflects the differences between the working directory and the index.
Maybe using git update-index --refresh would be more direct and
straightforward solution.
(Hi Victoria, do you have any comments? =)
Thanks
Shuqi
