diff: fix failed compare when ignoring file case

2022-02-18T15:51:38+00:00

With --ignore-file-name-case we need to compare files regardless of
case. We need to propigate both names down to diffit so we can look up
the correct file when the names differ based on case, otherwise we try
to look up the file using the case from the a tree which might not be
discoverable if its case is different in the b tree.

compare where the links point to.

diff: move functions around and reduce their visibility

2021-09-15T23:36:41+00:00

Most of them become static. There will be more such functions added in
upcoming commits, so they would be inconsistent with existing code.
Improve the existing code instead of reinforcing the unwanted pattern.

diff: Import fixes from OpenBSD

2018-06-09T21:09:24+00:00

original commit log by miller@OpenBSD  r1.46:
Fix exit value when diffing directories with missing files and the -N
or -P options are not used.  From Ibrahim Khalifa

Fix exit status with -rq when there is a file in one directory but not another,

2017-07-17T18:06:42+00:00

i.e., when print_only is called.

Prior to this change, -rq was always returning 0. After this change it will
return 1 if there is a difference between two directories.

This fixes compatibility with GNU diff and unbreaks backwards compatibility
expectations.

Found when trying to extend diff_test:brief_format_test.
