X Title: bpo-32230, bpo-20361: Set sys.warnoptions for all command line options by ncoghlan · Pull Request #4734 · python/cpython

Description: Rather than supporting dev mode and the command line BytesWarning flag directly in the warnings module, this instead adjusts the initialisation code to add extra entries to sys.warnoptions when these options are enabled. This ensures that dev mode behaves exactly as if -Wdefault had been passed on the command line, including in the way it interacts with sys.warnoptions, and with other command line flags like -bb. It also ensures that the -b and -bb options take precedence of other warnings filter options like -Wdefault or PYTHONWARNINGS=ignore. https://bugs.python.org/issue32230 https://bugs.python.org/issue20361
