From 85953a318734a9ad479626fbe53985da1475ec0b Mon Sep 17 00:00:00 2001 From: Johannes Schindelin Date: Wed, 1 Jul 2020 21:19:06 +0000 Subject: [PATCH] diff-files --raw: show correct post-image of intent-to-add files The documented behavior of `git diff-files --raw` is to display [...] 0{40} if creation, unmerged or "look at work tree". on the right hand (i.e. postimage) side. This happens for files that have unstaged modifications, and for files that are unmodified but stat-dirty. For intent-to-add files, we used to show the empty blob's hash instead. In c26022ea8f5 (diff: convert diff_addremove to struct object_id, 2017-05-30), we made that worse by inadvertently changing that to the hash of the empty tree. Let's make the behavior consistent with files that have unstaged modifications (which applies to intent-to-add files, too) by showing all-zero values also for intent-to-add files. Accordingly, this patch adjusts the expectations set by the regression test introduced in feea6946a5b (diff-files: treat "i-t-a" files as "not-in-index", 2020-06-20).
