[issue18690] memoryview not considered a sequence
New submission from Simon Feltman: This was a bit unexpected as memoryviews support all the methods of the Sequence abstract base class: >>> import collections >>> b = bytearray(b'asdf') >>> isinstance(b, collections.Sequence) True >>> m = memoryview(b) >>> isinstance(m, collections.Sequence) False It would be nice if memoryview was registered with the Sequence ABC and MutableSequence for writeable memoryviews. -- components: Library (Lib) messages: 194707 nosy: sfeltman priority: normal severity: normal status: open title: memoryview not considered a sequence type: behavior versions: Python 2.7, Python 3.1, Python 3.2, Python 3.3, Python 3.4, Python 3.5 ___ Python tracker <http://bugs.python.org/issue18690> ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue15715] __import__ now raises with non-existing items in fromlist in 3.3
New submission from Simon Feltman:
This came up while trying to build pygobject with Python 3.3. The problem is
there are some erroneous imports in the fromlist with these bindings that can
easily be fixed. But it is a behavioral change so I just wanted to raise
awareness if it is not already known.
$ python3.2 -c "__import__('http', fromlist=['blah'])"
(works)
$ python3.3 -c "__import__('http', fromlist=['blah'])"
Traceback (most recent call last):
File "", line 1, in
ImportError: No module named 'http.blah'
Note this is also the case when using the C API: PyImport_ImportModuleEx

Simon Feltman added the comment: I think pygobject still supports Python 2.5 which it look like importlib is available. I've submitted a patch to pygobject which will work regardless of if this regression is fixed or not: https://bugzilla.gnome.org/show_bug.cgi?id=682051 -- ___ Python tracker <http://bugs.python.org/issue15715> ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue16452] Add support for weak reference to bound methods
New submission from Simon Feltman: This is a feature request to include a "WeakMethod" or similar object to the weakref module. The object decomposes a bound method and holds a weakref to the object and unbound function. This can be a very useful utility in signal and ui based programming. The issue has come up a few times but I was unable to find a bug specifically requesting this feature. I think similar code has shown up in enough libraries at this point that it makes sense to just include it in pythons weakref module.

[issue14631] Instance methods and WeakRefs don't mix.
Simon Feltman added the comment: Just a note this is also referred to as a "WeakMethod" by some folks (so this ticket shows up in those searches).

[issue14631] Instance methods and WeakRefs don't mix.
Simon Feltman added the comment: The WeakCallableRef that was attached seemed to support regular functions (or anything callable) which is nice. The naming also leaves room for a WeakCallableProxy. -- ___ Python tracker <http://bugs.python.org/issue14631> ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Simon Feltman added the comment: Some more complex examples from various libraries: https://github.com/django/django/blob/master/django/dispatch/saferef.py https://github.com/11craft/louie/blob/master/louie/saferef.py I think both of these originated in pydispatcher. -- ___ Python tracker <http://bugs.python.org/issue14631> ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
