# Which issue does this PR close? - Closes #9716 . # Rationale for this change Current version serializes a length-0 offsets buffer, and relies on the array constructor to set offsets to `[0]` for empty arrays. This does not conform with spec, which specifies that the offsets buffer should have `length + 1` elements. This correctly serializes a length-1 offsets buffer containing `[0]`. I have left the current behavior of filling-in offsets with `[0]` for empty arrays, so that future versions can still read IPC files serialized by previous versions. # What changes are included in this PR? Added tests for serialization of empty arrays, ensuring length-1 offsets buffer. Fixed serialization of empty arrays. This fixes serialization of empty Binary/Utf8/List/LargeList (and Map) arrays. # Are these changes tested? Yes # Are there any user-facing changes? There should not be any breaking change for users. Serialized files for empty record batches will be slightly different. Older serialized files should still be read fine. -- This is an automated message from the Apache Git Service.
