New submission from Kyle Altendorf <s...@fstab.net>: Normally sys.argv is a list but when using the trace module sys.argv gets changed to a tuple. In my case this caused an issue with running an entry point due to the line:
sys.argv[0] = re.sub(r'(-script\.pyw?|\.exe)?$', '', sys.argv[0]) When researching I found: https://stackoverflow.com/questions/47688568/trace-sys-argv-args-typeerror-tuple-object-does-not-support-item-assig They point out where trace assigns a tuple to sys.argv. https://github.com/python/cpython/blob/master/Lib/trace.py#L708 I'll see what I can do to put together a quick patch. $ cat t.py import sys print(sys.version) print(type(sys.argv)) $ /home/altendky/.pyenv/versions/3.7.0a2/bin/python t.py 3.7.0a2 (default, Feb 15 2018, 11:20:36) [GCC 6.3.0 20170516] <class 'list'> $ /home/altendky/.pyenv/versions/3.7.0a2/bin/python -m trace --trace t.py --- modulename: t, funcname: <module> t.py(1): import sys t.py(3): print(sys.version) 3.7.0a2 (default, Feb 15 2018, 11:20:36) [GCC 6.3.0 20170516] t.py(5): print(type(sys.argv)) <class 'tuple'> --- modulename: trace, funcname: _unsettrace trace.py(71): sys.settrace(None) ---------- components: Library (Lib) messages: 312213 nosy: altendky priority: normal severity: normal status: open title: trace changes sys.argv from list to tuple versions: Python 3.6, Python 3.7 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue32852> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
