read_fwf
was usingcompression=None
to infer compression (in addition tocompression="infer"
). This is undocumented but was enforced in a test.In #37639, I thought this was the expected behavior for all functions. That as wrong,
read_csv
explicitly states thatcompression=None
does not infer any compression.
