Subject: [PATCH v5 1/2] diff-files --raw: show correct post-image of intent-to-add files
Date: Wed, 01 Jul 2020 21:19:06 +0000	[thread overview]
Message-ID: <4392ae4be6ff4f1baad4bba7d166a0aaf634ca6e.1593638347.git.gitgitgadget@gmail.com> (raw)
In-Reply-To: <pull.654.v5.git.1593638347.gitgitgadget@gmail.com>

From: Johannes Schindelin <johannes.schindelin@gmx.de>

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).
