Serhiy Storchaka <storchaka+cpyt...@gmail.com> added the comment:
Oh, LZMAFile.write() should not use len() directly on input data because it
does not always work correctly with memoryview and other objects supporting the
buffer protocol. It should use memoryview(data).nbytes or data =
memoryview(data).cast('B') if other byte-oriented operations (indexing,
slicing) are used. See for example Lib/gzip.py, Lib/_pyio.py,
Lib/_compression.py, Lib/ssl.py, Lib/socketserver.py, Lib/wave.py.
