Subject: [PATCH v5 0/6] patch-id fixes and improvements
Date: Mon, 24 Oct 2022 20:07:38 +0000	[thread overview]
Message-ID: <pull.1359.v5.git.1666642064.gitgitgadget@gmail.com> (raw)
In-Reply-To: <pull.1359.v4.git.1666307815.gitgitgadget@gmail.com>

These patches add fixes and features to the "git patch-id" command, mostly
discovered through our usage of patch-id in the revup project
(https://github.com/Skydio/revup). On top of that I've tried to make general
cleanup changes where I can.

Summary:

1: Fixed a bug in the combination of --stable with binary files and
header-only, and expanded the test to cover both binary and non-binary
files.

2: Switch internal usage of patch-id in rebase / cherry-pick to use the
stable variant to reduce the number of code paths and improve testing for
bugs like above.

3: Fixed bugs with patch-id and binary diffs. Previously patch-id did not
behave correctly for binary diffs regardless of whether "--binary" was given
to "diff".

4: Fixed bugs with patch-id and mode changes. Previously mode changes were
incorrectly excluded from the patch-id.

5: Add a new "--include-whitespace" mode to patch-id that prevents
whitespace from being stripped during id calculation. Also add a config
option for the same behavior.

6: Remove unused prefix from patch-id logic.

V1->V2: Fixed comment style V2->V3: The ---/+++ lines no longer get added to
the patch-id of binary diffs. Also added patches 3-7 in the series. V3->V4:
Dropped patch7. Updated flag name to --verbatim. Updated commit message
descriptions. V4->V5: Updated commit message for patch 6.

          builtin: patch-id: remove unused diff-tree prefix
      
     -    From a "git grep" of the repo, no command, including diff-tree itself,
     -    produces diff output with "diff-tree " prefixed in the header.
     +    The last git version that had "diff-tree" in the header text
     +    of "git diff-tree" output was v1.3.0 from 2006. The header text
     +    was changed from "diff-tree" to "commit" in 91539833
     +    ("Log message printout cleanups").
      
     -    Thus remove its handling in "patch-id".
     +    Given how long ago this change was made, it is highly unlikely that
     +    anyone is still feeding in outputs from that git version.
     +
     +    Remove the handling of the "diff-tree" prefix and document the
     +    source of the other prefixes so that the overall functionality
     +    is more clear.
