Subject: [PATCH 2/4] t6038: fix test with obviously incorrect expectations
Date: Sun, 02 Aug 2020 06:33:04 +0000
Message-ID: <83a50f7e0bbfd19cffc5cffb9f17484e86443d0a.1596349986.git.gitgitgadget@gmail.com> (raw)
In-Reply-To: <pull.825.git.git.1596349986.gitgitgadget@gmail.com>

From: Elijah Newren <newren@gmail.com>

t6038.11, 'cherry-pick patch from after text=auto' was set up so that on
a branch with no .gitattributes file, you cherry-picked a patch from a
branch that had a .gitattributes file (containing '* text=auto').
Further, the two branches had a file which differed only in line
endings.  In this situation, correct behavior is not well defined:
should the .gitattributes file affect the merge or not?

If the .gitattributes file on the other branch should not affect the
merge, then we would have a content conflict with all three stages
different (the merge base didn't match either side).

If the .gitattributes file from the other branch should affect the
merge, then we would expect the line endings to be normalized to LF so
that the versions from both sides match, and then the cherry-pick has no
conflicts and can succeed.  After the cherry-pick, the line endings in
the file will change from CRLF to LF.

This test had an expectation that the line endings would remain CRLF.
Further, it expected an error message that was built assuming
cherry-pick was the old scripted version, because cherry-pick no longer
uses the error message that was encoded in this test.  So, although I
don't know what correct behavior for this test is, I know that this test
was not testing for it.

Since I have no idea which of the two cases above provides correct
behavior, let's just assume for now it's the case where we assume that
.gitattributes affects the merge and update it accordingly.
