Add na_filter to the pyarrow-engine unsupported-options set so that read_csv(..., engine="pyarrow", na_filter=False) raises a clear ValueError instead of silently performing NA filtering anyway. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

read_csvwithengine="pyarrow"never forwardedna_filterto pyarrow'sConvertOptions, sona_filter=Falsewas silently ignored — NA detection happened anyway, producing results that differed from the c/python engines. This addsna_filterto the pyarrow-engine unsupported-options set so the standardValueError: The 'na_filter' option is not supported with the 'pyarrow' engineis raised instead.The corresponding xfailed tests (
test_na_values_na_filter_override,test_no_na_filter_on_index,test_na_values_with_dtype_str_and_na_filter,test_parse_dates_empty_string) now assert that error.🤖 Generated with Claude Code
