lichen2015 bdf58fc2d2 fix: prevent SIGABRT when adding nullable column to multi-segment collection (#415) (#416) ... When add_column is called on a multi-segment collection with a nullable field and no expression, segment.cc previously sliced an Arrow ChunkedArray with an offset that exceeded the array length, triggering SIGABRT in Arrow's chunked_array.cc:170 assertion. Fix the slicing logic in segment.cc to materialize null values per segment. Add comprehensive tests in collection_test.cc and segment_test.cc covering multi-segment add_column scenarios (nullable/non-nullable, with/without expression, with/without unflushed data, drop+re-add).		2026-05-24 14:13:57 +08:00
