New submission from STINNER Victor <victor.stin...@gmail.com>: In the review of the PR 4478, Antoine Pitrou proposed to add an environment variable to enable the new Python "developer mode" to inherit the developer mode in child Python processes.
I proposed to add PYTHONDEVMODE=1. Nick Coghlan proposed PYTHONXOPTIONS=dev. While -X is a new "catch all" for new CPython options, Python got new PYTHONxxx environment variables to enable new options: * -X faulthandler: PYTHONFAULTHANDLER=1 * -X tracemalloc=N: PYTHONTRACEMALLOC=n * -X importtime: PYTHONPROFILEIMPORTTIME=1 -- note that the names are different in this case, I don't know why I have a preference for PYTHONDEVMODE=1. If we start to use PYTHONXOPTIONS, users may want to use PYTHONXOPTIONS=tracemalloc, and then we have to decide which environment variable has the preference :-( Moreover, tracemalloc takes an argument, whereas environment variables with a value containing '=' are rare and so likely to cause issues in programs not carefully written to handle such variables. (Environment variables are inherited by all processes, not only Python processes.) ---------- messages: 306618 nosy: ncoghlan, pitrou, vstinner priority: normal severity: normal status: open title: Add PYTHONDEVMODE=1 to enable the developer mode type: enhancement versions: Python 3.7 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue32101> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
