So the change makes sense to me.

This looks like it turns hints back on specifically for this case, but might not fix other places where ea9882bfc4 turned them off. I think the intent of that commit was to not put hints into the editor, so does it make sense to instead wrap this guy: /* * Most hints are counter-productive when the commit has * already started. */ s->hints = 0; in "if (use_editor)"? I didn't try it on my end. Maybe it won't help much, because we think we're going to use the editor right up until we realize it's not committable? I wonder which other cases that commit got rid of hints for by accident. - Emily > s->display_comment_prefix = old_display_comment_prefix; > run_status(stdout, index_file, prefix, 0, s); > if (amend) > diff --git a/t/t7500-commit-template-squash-signoff.sh b/t/t7500-commit-template-squash-signoff.sh > index 46a5cd4b73..3d76e8ebbd 100755 > --- a/t/t7500-commit-template-squash-signoff.sh > +++ b/t/t7500-commit-template-squash-signoff.sh > @@ -382,4 +382,13 @@ test_expect_success 'check commit with unstaged rename and copy' ' > ) > ' > > +test_expect_success 'commit without staging files fails and displays hints' ' > + echo "initial" >>file && > + git add file && > + git commit -m initial && > + echo "changes" >>file && > + test_must_fail git commit -m initial >actual && > + test_i18ngrep "no changes added to commit (use \"git add\" and/or \"git commit -a\")" actual > +' > + > test_done > -- > gitgitgadget

Still probably worth a comment, though. For example: This status is to be printed to stdout, so hints will be useful to the user. Reset s->hints to what the user configured. The corresponding comment on "s->hints = 0" might need to be tweaked, too, but I can't think of anything at the moment. > +test_expect_success 'commit without staging files fails and displays hints' ' > + echo "initial" >>file && > + git add file && > + git commit -m initial && > + echo "changes" >>file && > + test_must_fail git commit -m initial >actual && Use another commit message for this, since this is no longer "initial". (Maybe "after initial" or something like that.)
