Message276663
I realised I wasn't entirely clear about the "warning misattribution" problem that's implied by Chi Hsuan's problem report, so here's the behaviour when using "-W all" rather than "-W error":
$ echo "print('\d')" > bad_escape.py
$ echo "import bad_escape" > escape_warning.py
$ ./python -W all escape_warning.py
_frozen_importlib:205: DeprecationWarning: invalid escape sequence '\d'
\d
That's a misattribution - the warning should be reported against the module being imported, not against the import system itself.
Compare that to the attribution of the old SyntaxWarning for assignments prior to a scope declaration:
$ cat syntax_warning.py
def f():
x = 1
global x
$ python3 -c "import syntax_warning"
/home/ncoghlan/devel/py36/syntax_warning.py:3: SyntaxWarning: name 'x' is assigned to before global declaration
global x
(Run with 3.5, as that became a full SyntaxError for 3.6) |
