[PATCH] t7610-mergetool: add test cases for tempfile behavior

David Aguilar· Mar 9, 2016, 05:36 UTC · lore

Ensure that mergetool.keepTemporaries is honored when resolving delete/delete conflicts.

Ensure that stderr stays empty, and that worktree directories created by mergetool to are removed.

Thanks.

We'd like to catch a newly built Git segfaulting, so let's change this to:

	test_must_fail git merge move-to-b &&

Two other "! git merge" in this patch need be changed the same way.

Show 25 quoted lines

Let's use EOF not -EOF as the end marker for here document, but use a dash in front of the marker to allow us indent the contents of the here document, like this:

	cat >expect <<-\EOF &&
	file_BASE_.txt
	file_LOCAL_.txt
	file_REMOTE_.txt
	EOF

While at it, let's lose the extra SP after "cat".

Show 8 quoted lines

> +	git clean -fdx &&

>  	git checkout -b test6 branch1 &&
>  	git submodule update -N &&

I'll queue this patch with the above-mentioned fixups squashed in, but I suspect that another new test added by the previous patches have the same "! git merge" issue we'd want to correct before we start to move the topic to 'next' and to 'master', so perhaps you'd want to reroll these three patches as two patches (i.e. squashing this one to 1/2, correcting the test in 2/2) after 2.8 final ships?

Thanks.
