Subject: [PATCH 1/3] t6423: add tests of dual directory rename plus add/add conflict
Date: Wed, 22 Jun 2022 04:20:49 +0000 [thread overview]
Message-ID: <69d6204184363e491acb68f744ded0991be63a47.1655871652.git.gitgitgadget@gmail.com> (raw)
In-Reply-To: <pull.1268.git.1655871651.gitgitgadget@gmail.com>
From: Elijah Newren <newren@gmail.com>
This is an attempt at minimalizing a testcase reported by Glen Choo
with tensorflow where merge-ort would report an assertion failure:
Assertion failed: (ci->filemask == 2 || ci->filemask == 4), function apply_directory_rename_modifications, file merge-ort.c, line 2410
reversing the direction of the merge provides a different error:
error: cache entry has null sha1: ...
fatal: unable to write .git/index
so we add testcases for both. With these new testcases, the
recursive strategy differs in that it returns the latter error for
both merge directions.
These testcases are somehow a little different than Glen's original
tensorflow testcase in that these ones trigger a bug with the recursive
algorithm whereas his testcase didn't. I figure that means these
testcases somehow manage to be more comprehensive.
