Junio C Hamano c8f491668e Merge branch 'dd/diff-files-unmerged-fix'
"git diff --relative" segfaulted and/or produced incorrect result
when there are unmerged paths.

* dd/diff-files-unmerged-fix:
  diff-lib: ignore paths that are outside $cwd if --relative asked

Đoàn Trần Công Danh 8174627b3d diff-lib: ignore paths that are outside $cwd if --relative asked
For diff family commands, we can tell them to exclude changes outside
of some directories if --relative is requested.

In diff_unmerge(), NULL will be returned if the requested path is
outside of the interesting directories, thus we'll run into NULL
pointer dereference in run_diff_files when trying to dereference
its return value.

Checking for return value of diff_unmerge before dereferencing
is not sufficient, though. Since, diff engine will try to work on such
pathspec later.

Let's not run diff on those unintesting entries, instead.
As a side effect, by skipping like that, we can save some CPU cycles.

Ævar Arnfjörð Bjarmason 1108cea7f8 tests: remove most uses of test_i18ncmp
As a follow-up to d162b25f95 (tests: remove support for
GIT_TEST_GETTEXT_POISON, 2021-01-20) remove most uses of test_i18ncmp
via a simple s/test_i18ncmp/test_cmp/g search-replacement.

I'm leaving t6300-for-each-ref.sh out due to a conflict with in-flight
changes between "master" and "seen", as well as the prerequisite
itself due to other changes between "master" and "next/seen" which add
new test_i18ncmp uses.

Laurent Arnoud c28ded83fc diff: add config option relative
The `diff.relative` boolean option set to `true` shows only changes in
the current directory/value specified by the `path` argument of the
`relative` option and shows pathnames relative to the aforementioned
directory.

Teach `--no-relative` to override earlier `--relative`

Add for git-format-patch(1) options documentation `--relative` and
`--no-relative`

Jacob Keller 6d7c17ec9d diff: add tests for --relative without optional prefix value
We already have tests for --relative, but they currently only test when
a prefix has been provided. This fails to test the case where --relative
by itself should use the current directory as the prefix.

Teach the check_$type functions to take a directory argument to indicate
which subdirectory to run the git commands in. Add a new test which uses
this to test --relative without a prefix value.

Zbigniew Jędrzejewski-Szmek dc801e71a7 diff --stat: use less columns for change counts
Number of columns required for change counts is now computed based on
the maximum number of changed lines instead of being fixed. This means
that usually a few more columns will be available for the filenames
and the graph.

The graph width logic is also modified to include enough space for
"Bin XXX -> YYY bytes".

If changes to binary files are mixed with changes to text files,
change counts are padded to take at least three columns. And the other
way around, if change counts require more than three columns, then
"Bin"s are padded to align with the change count. This way, the +-
part starts in the same column as "XXX -> YYY" part for binary files.
This makes the graph easier to parse visually thanks to the empty
column. This mimics the layout of diff --stat before this change.

Tests and the tutorial are updated to reflect the new --stat output.
This means either the removal of extra padding and/or the addition of
up to three extra characters to truncated filenames. One test is added
to check the graph alignment when a binary file change and text file
change of more than 999 lines are committed together.

Nguyễn Thái Ngọc Duy 7f814632f5 Use correct grammar in diffstat summary line
"git diff --stat" and "git apply --stat" now learn to print the line
"%d files changed, %d insertions(+), %d deletions(-)" in singular form
whenever applicable. "0 insertions" and "0 deletions" are also omitted
unless they are both zero.

This matches how versions of "diffstat" that are not prehistoric produced
their output, and also makes this line translatable.

[jc: with help from Thomas Dickey in archaeology of "diffstat"]
[jc: squashed Jonathan's updates to illustrations in tutorials and a test]

Jakub Narebski d8faea9d18 diff: strip extra "/" when stripping prefix
There are two ways a user might want to use "diff --relative":

  1. For a file in a directory, like "subdir/file", the user
     can use "--relative=subdir/" to strip the directory.

  2. To strip part of a filename, like "foo-10", they can
     use "--relative=foo-".

We currently handle both of those situations. However, if the user passes
"--relative=subdir" (without the trailing slash), we produce inconsistent
results. For the unified diff format, we collapse the double-slash of
"a//file" correctly into "a/file". But for other formats (raw, stat,
name-status), we end up with "/file".

We can do what the user means here and strip the extra "/" (and only a
slash).  We are not hurting any existing users of (2) above with this
behavior change because the existing output for this case was nonsensical.

Patch by Jakub, tests and commit message by Jeff King.
