Hi Duy, the change itself looks good, but... On Thu, 17 Jan 2019, Nguyễn Thái Ngọc Duy wrote:
diff_opt_parse() is a heavy hammer to just set diff filter. But it's the only way because of the diff_status_letters[] mapping. Add a new API to set diff filter and use it in git-am. diff_opt_parse()'s only remaining call site in revision.c will be gone soon and having it here
... "will be gone soon"? Does that mean that you mail-bomb another mega patch series iteration once you did that, now sending 77 or 78 patches? I don't know about others, but I can only afford to spend a fraction of my waking hours on reviews, and even back when Christian sent the built-in am as a loooong patch series it was *already* a big problem. Thankfully he seems to have decided to never do that again. It would probably make sense to break your 76-strong patch series down into at least four separate patch series, they would still be as long as my Azure Pipelines one (which is longer than I am actually comfortable with, but in my case, it was necessary, while your patch series consists of many, mostly independent patches that could even be wrapped into individual patch series of 1 or 2). It's just way too much to review if you present it in the current manner. Ciao, Johannes
