FieldMask.Intersect() on disjoint paths results in FieldMask with empty string in paths #5518

Closed timnd closed 5 years ago

What version of protobuf and what language are you using? Version: v3.6.1 Language: Python

What operating system (Linux, Windows, ...) and version? MacOS High Sierra

What runtime / compiler are you using (e.g., python version or gcc version) python 3.6.5

What did you do? Steps to reproduce the behavior: from google.protobuf import field_mask_pb2 fm1 = field_mask_pb2.FieldMask(paths=['a']) fm2 = field_mask_pb2.FieldMask(paths=['b']) fm_int = field_mask_pb2.FieldMask() fm_int.Intersect(fm1, fm2)

fm_int.paths ['']

What did you expect to see fm_int.paths == [] What did you see instead? fm_int.paths == ['']

Make sure you include information that can help us debug (full error message, exception listing, stack trace, logs).

Thanks for raise the bug up. I've fixed in internal code, expected to see in future release
