Daniel Holth added the comment: As an aside, why wouldn't I run my program with -bb? One reason is that the following code won't work on Linux: #!/usr/bin/env python -bb Instead of passing -bb to Python, it will look for an executable called "python -bb", and it's not likely to find it. The

Daniel Holth added the comment: Python 3 is supposed to make it easier to do Unicode correctly. str(bytes) does not. I felt strongly enough about that to write this patch. With this feature my library can have control in a way that is much more practical than ensuring a particular flag has bee

R. David Murray added the comment: I presume you mean you are motivated to turn it on (to catch the bugs). I still think that also fixing the bugs in the other places str(bytes) is used would be better. Are they occurring in third party libraries? How often do you run into it? --

Serhiy Storchaka added the comment: Read only access to bytes warning flag already implemented as sys.flags.bytes_warning. How new functions are related to it? And I concur with David. Why not just run your program with -b or -bb? Besides the testing purpose. -- nosy: +serhiy.storchak

[issue18373] implement sys.get/setbyteswarningflag()

New submission from Daniel Holth: This patch lets the user get/set the byteswarningflag() to control whether warnings are emitted at runtime (pursuant to the configuration of the warnings module, of course). The idea is that a user who is concerned with interacting with bytes correctly would
