patch 9.0.2146: text-property without type errors when joining Commit: https://github.com/vim/vim/commit/0d0b3b19517c321b089d637919e88e49a07a3d85 Author: Christian Brabandt <cb@256bit.org> Date: Sun Dec 3 17:56:43 2023 +0100 patch 9.0.2146: text-property without type errors when joining Problem: text-property without type errors when joining Solution: count all text-properties, with or without type before joining lines Error when joining lines with text properties without a proper type When joining lines, we need to consider all text properties that are attached to a line, even when those text properties are invalid and do not have a type attached to them. However, since patch v9.0.0993 (commit: 89469d157aea01513bde826b4519dd6b5fbceae4) those text properties won't be counted when joining lines and therefore this will cause the adjustment for text properties on joining to go wrong (and may later cause SIGABRT with an invalid free pointer) I am not sure, why the condition to not count text properties with a valid type was added in patch v9.0.993, because no test fails if those condition is removed. So let's just remove this condition and add a test that verifies, that we are able to join lines, even when the text properties attached to it do not have a valid type. fixes: #13609 closes: #13614 Signed-off-by: Christian Brabandt <cb@256bit.org>
