STINNER Victor added the comment: > _setmode(self->fd, O_BINARY) change was done in Python 3.2: see the issue > #10841
The main reason was to be able to read binary file from sys.stdin using the CGI module: see the issue #4953. In _O_TEXT mode, 0x0A byte is replaced with 0x0A 0x0D (or the opposite, I never remember) which corrupt binary files.
