[issue13153] IDLE crash with unicode bigger than 0xFFFF

[issue13185] Why does Python interpreter care about curvy quotes in comments?
Martin v. Löwis mar...@v.loewis.de added the comment: The error message told you exactly what the problem is. Your source file does not conform to PEP 263. The PEP also explains why this applies to comments as well: because the entire file gets decoded according to the source encoding, and parsing (including determining what comments are) only starts afterwards.

[issue7317] Display full tracebacks when an error occurs asynchronously
Julian python_...@somethinkodd.com added the comment: The formatting isn't very conventional for Python. Why not use the normal format? i.e. Traceback (most recent call last): File /tmp/bla.py, line 4, in __del__ None.someattr AttributeError: 'NoneType' object has no attribute 'someattr' Why is this more likely to get confused with user input than other unhandled exceptions? If you ARE going to deviate, it may be helpful to have it explain why this exception wasn't caught through the normal channels. Maybe the last line could be: Failed to raise this exception in __del__/finalizer method. or similar. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue7317 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue13186] instance_ass_item() broken in classobject.c (Py2.7)
New submission from Stefan Behnel sco...@users.sourceforge.net:
Starting at line 1223 in classobject.c, you can find this code:
if (item == NULL)
arg = PyInt_FromSsize_t(i);
else
arg = Py_BuildValue((nO), i, item);
if (arg == NULL) {
Py_DECREF(func);
return -1;
}
res = PyEval_CallObject(func, arg);
If item is NULL, arg will be assigned an int object. Otherwise, it will receive
a tuple. Only the second case works in the subsequent call to
PyEval_CallObject(), i.e. arg must always be assigned an argument tuple.
A quick fix would be to call Py_BuildValue((n), i) in the first case. The
code just did a getattr(), so this is not performance critical anymore.
I found this bug because the test_class.py test suite was failing in Cython.

[issue13139] multiprocessing.map skips finally blocks
Antoine Pitrou pit...@free.fr added the comment: As mentioned in http://docs.python.org/dev/library/multiprocessing#multiprocessing.pool.AsyncResult.get “If the remote call raised an exception then that exception will be reraised by get().” map() is just map_async() followed by a get() call on the result. Also, worker processes are called in daemon mode, which explains that children get killed as soon as the parent exits. If you rephrase your example as: try: Pool(3).map(Process, ['1','2','3']) finally: sleep(1) then all the children's finally clauses get a chance to be executed before the parent exits. I would therefore call it not a bug, although you might add a sentence in the map() documentation stating that an exception is raised as soon as one of the worker fails. -- assignee: - docs@python components: +Documentation nosy: +docs@python, pitrou ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue13139 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue13179] IDLE uses common tkinter variables across all editor windows
Roger Serwy roger.se...@gmail.com added the comment: For Code Context, the behavior is a bug since the menu item check can be changed independently of the actual status of Code Context. As far as I can tell, flist.vars mostly contains variables created by EditorWindow.py's get_var_obj. A quick grep for .vars in idlelib can confirm that. It also contains variables created by PyShell.py, particularly 'toggle-jit-stack-viewer' and 'toggle-debugger'. Since the shell can only have one instance, its tkinter variables can be held local to the EditorWindow instance. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue13179 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue13153] IDLE crash with unicode bigger than 0xFFFF
Ezio Melotti ezio.melo...@gmail.com added the comment:
Ezio, do you know anything about these speculations?
Assuming that the non-BMP character is represented with two surrogates
(\ud801\udca2) and that _tkinter tries to decode them independently, the error
message (invalid continuation byte) would be correct.
Python 2 UTF-8 codec is more permissive and allows encoding/decoding of
surrogates (this might also explain why it works on Python 2):
u'\ud801'.encode('utf-8')
'\xed\xa0\x81'
'\xed\xa0\x81'.decode('utf-8')
u'\ud801'
But on Python 3, trying to decode that results in an error:
b'\xed\xa0\x81'.decode('utf-8')
Traceback (most recent call last):
File stdin, line 1, in module
UnicodeDecodeError: 'utf8' codec can't decode bytes in position 0-1: invalid
continuation byte
But then the problem should be the initial byte, not the continuation
bytes, which are the same for all chars and which all have 10 for
their two high order bits.
While it's true that all continuation bytes have the first two bits equal to
'10', the opposite is not always true. Some start bytes have additional
restrictions on the continuation bytes. For example, even if the first two
bits of 0xA0 (0b1010) are '10', the valid continuation bytes for a sequence
starting with 0xED are restricted to the range 80..9F.
The fact that
'\U000104a2'
'Ң'
works is because the input is all ASCII, so the decoding doesn't fail.
[...]
This should catch any miscellaneous crashes which are not otherwise
caught and maybe turn the crash issues into bug reports -- the same
way that running from the command line did.
Having some safe net to catch all the unhandled exceptions seems like a good
idea. This won't work in case of segfaults, but it's still better than
nothing. I'm not sure what you mean with turn them into bug reports though.
