[issue1621] Do not assume signed integer overflow behavior

Martin Panter added the comment: unicode.patch avoids an overflow in PyUnicode_Join(): >>> size = int(sys.maxsize**0.5) + 1 >>> "".join(("A" * size,) * size) Objects/unicodeobject.c:9927:12: runtime error: signed integer overflow: 46341 + 2147441940 cannot be represented in type 'int'

[issue27605] Inconsistent calls to __eq__ from built-in __contains__

New submission from Vasiliy Faronov: Consider the attached example program. I expect it to run successfully, because the Python 3 language reference says [1]: > For container types such as list, tuple, set, frozenset, dict, or > collections.deque, the expression `x in y` is equivalent to

[issue1621] Do not assume signed integer overflow behavior

Martin Panter added the comment: Xiang: I don’t think we need to make the tests do anything special. Just make sure they exercise the code that handles overflows. I have been running the test suite without any -j0 option, and I can look over the output and see the error messages. Or if we get

[issue27604] More details about `-O` flag

New submission from Ram Rachum: I wanted to ensure that the `-O` flag doesn't really do anything more than remove assert statement and make `__debug__` equal `False`. But the documentation for `-O` doesn't cover it: https://docs.python.org/3/using/cmdline.html#cmdoption-O

[issue27366] PEP487: Simpler customization of class creation

Martin Teichmann added the comment: Thanks for the nice review! I made the proposed changes, see attached patch. I am still waiting for a decision whether type.__setattr__ should call __set_name__ from python-dev, once that's sorted out I'll implement and test the one or the other behavior.

[issue26823] Shrink recursive tracebacks

Nick Coghlan added the comment: Thanks Emanuel, and sorry for the long delay in getting a review! My main substantive comment is that the approach of hardcoding the recursion count won't work cross platform, as the default recursion limit is set differently depending on how the platform's C

[issue26152] A non-breaking space in a source

Nick Coghlan added the comment: http://bugs.python.org/issue27582 is a later mention of the same problem that attracted patches before Adam noticed it was a repeat of this issue. Marking this as the duplicate, since the problem applies to more than just Unicode whitespace, and the problems

Nick Coghlan added the comment: Martin's current implementation basically looks good to me - I've mainly suggested some changes to the documentation and additional test cases that help stress test some of the more complex inheritance hierarchies described above, although there are a few other

[issue1621] Do not assume signed integer overflow behavior

Xiang Zhang added the comment: It's cool, but I get one problem when writing tests. support.captured_stderr cannot capture the runtime error message. So we have nothing to do with the assertion and the test will always succeed even when overflow does happen (the message will be output). To

[issue27581] Fix overflow check in PySequence_Tuple

Martin Panter added the comment: I don’t accept that the bltinmodule.c code is similar to your patch. It gets a size_t from calling strlen() on a string that potentially comes from outside Python, so it is definitely valid to check for PY_SSIZE_T_MAX. However I did find PyByteArray_Resize()
