[issue19002] ``dir`` function does not work correctly with classes.
New submission from David Halter: I recently stumbled over the ``dir`` function not working correctly with classes. This means that ``dir(object)`` won't list ``object.__bases__`` or ``object.__subclasses`` (and many other useful methods). I think that we should change that. The C function ``type_dir`` (in ``Objects/typeobject.c``) has a documentation entry which states: We deliberately don't suck up its __class__, as methods belonging to the metaclass would probably be more confusing than helpful. I think that that's not true. The current behaviour of ``dir`` is way more confusing, since ``dir`` is typically the tool how we find out about magic methods.

[issue17797] Visual C++ 11.0 reports fileno(stdin) == 0 for non-console program
Daniel added the comment: Here are some solutions which might help you until MS fixed the bug. 1) Even if the subsystem is Windows one solution is to call AllocConsole() before Py_Initialize() to create a console. 2) Second Solution: If you don't want to open a console and your application has its own output window you could redirect stdout/stderr/stdin with freopen to a temp file first. (e.g: freopen(file.txt,w,stdout);) Call freopen for all std handles before you call Py_Initialize(). You can keep the redirection to the file or after Py_Initialize() succeeded you change the redirection now in Python by redirect sys.stdout to the place you want. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue17797 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue18987] distutils.utils.get_platform() for 32-bit Python on a 64-bit machine
Sam Ferencik added the comment: Unfortunately, I don't have a patch. Some thoughts: To discover a 32-bit interpreter running on a 64-bit system, we could use platform.architecture(), which returns platform.architecture() ('32bit', 'ELF') What then, though? How do you turn '32bit' to 'linux-i386'? The naive solution would be to hard-code this as an exception: - if 32-on-64, use 'i386' - otherwise, use os.uname()[4], i.e. 'i386' or 'x86_64' I suspect that's ultra naive, though. The get_platform() code deals with a number of Unix-like systems (Solaris, AIX, ...). Even if we accepted this solution only for Linux, leaving the other OSs broken, is 'i386' always the right answer, or would 'i586' or similar be appropriate in some cases? We could also take inspiration from Mac OS (_osx_support.get_platform_osx()), which basically ignores os.uname()[4] completely and constructs the return value from a set of hard-coded values ('i386' being one of them).

[issue19004] datetime: Read in isoformat() output
New submission from Timothy Pederick: At present, the datetime module does not provide the capability to parse its own output from the isoformat() methods. strptime() can't handle timezones with colons in them (and anyway it seems to me you'd need to try several possible format strings depending on ' ' vs 'T' separators, presence/absence of microseconds, pres/abs timezone...). Adding this capability would be one option (%f already establishes a precedent for adding codes outside of what C supports). Another, perhaps superior option would be a specific method for parsing the output of isoformat(). -- components: Library (Lib) messages: 197482 nosy: perey priority: normal severity: normal status: open title: datetime: Read in isoformat() output type: enhancement versions: Python 3.3 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue19004 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue18999] Robustness issues in multiprocessing.{get, set}_start_method
Olivier Grisel added the comment: Maybe it would be better to have separate contexts for each start method. That way joblib could use the forkserver context without interfering with the rest of the user's program. Yes in general it would be great if libraries could customize the multiprocessing default options without impacting any of the module singletons. That also include the ForkingPickler registry for custom: now it's a class attribute. It would be great to be able to scope custom reducers registration to a given multiprocessing.Pool or multiprocessing.Process instance. Now how to implement that kind of isolation: it could either be done by adding new constructor parameters or new public methods to the Process and Pool classes to be able to customize their behavior while sticking to the OOP paradigm if possible or by using a context manager as you suggested. I am not sure which option is best.

[issue18967] Find a less conflict prone approach to Misc/NEWS
Ezio Melotti added the comment: IMHO the status quo is fine. Most of the time HG gets the merge right on its own. Some times kdiff3 pops up and asks me to solve the conflict [0]. Rarely something goes wrong so I just revert Misc/NEWS and re-add the entry manually. It seems to me that they are much rarer than they were with svn. I agree -- I think many of us still see merges as something bad that should be avoided, while this is generally no longer true with HG (it was with SVN). A similar argument is whitespace/PEP8 changes on 3.4 should be avoided because it makes merging changes from 3.3 more difficult. While it's true that it makes 3.4 diverge from 3.3, IME this doesn't really bother HG and merges usually goes smoothly (there are other arguments against that kind of changes, but I think this is not a very strong one). [0]: this usually happens when there is an entry in 3.4 only and I'm merging from 3.3. kdiff3 asks me if it should use the entry I added in 3.3 or the one that is in 3.4, and all I have to do is telling it to keep them both (ctrl+3/ctrl+2). -- nosy: +ezio.melotti ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue18967 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Ethan Furman added the comment: It's going to take more than I think that that's not true, to get a change made. From http://docs.python.org/2/library/functions.html#dir : Because dir() is supplied primarily as a convenience for use at an interactive prompt, it tries to supply an interesting set of names more than it tries to supply a rigorously or consistently defined set of names [...] . Currently, `dir(cls)` returns information that tells us how instances of that class will behave. Because metaclass methods have no direct effect on instance behavior, having dir return metaclass methods and attributes would be confusing. If you want to know how a class is going to behave you need to `dir(cls.__class__)`. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue19002 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue19006] UnitTest docs should have a single list of assertions
Ezio Melotti added the comment: There's nothing fundamentally different about the two lists I made that division because the ones in the first table are the most common and widely used, and are quite general too. The second table contains assert methods about catching exceptions and warnings, and, while still common, they are different from the first group. The third table has additional assertions that are quite specific and not used too often, and many of these have been added later on. There's also a fourth table with additional type-specific assertions, but they shouldn't be used directly. Also note that the list of methods is different on 3.x, even though I kept the same division on all the branches. These should be merged into a single list. Having a table with all the assert methods would indeed provide a better overview, but it would be quite a big table (25 assert methods on 3.4, excluding the type-specific ones) and might make navigation more difficult while scrolling through the methods. Something could be done to make clear that there are other tables down below though (e.g. adding links or using sub-sections with an index). -- nosy: +ezio.melotti, michael.foord type: - enhancement versions: +Python 3.3, Python 3.4 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue19006 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue19002] ``dir`` function does not work correctly with classes.
R. David Murray added the comment: That's not how people use it at the interactive prompt, though. I call dir(str) to find what methods I can call on an str object, not what methods I can call on the str class object. Same goes for my own classes. Yes, I also call it on instances, but it would be very surprising, especially at this point in Python's history, for this to change. It would also screw up pydoc and inspect. Screwing up inspect is an issue Ethan has already brought up as a possible problem regardless, but that doesn't really enter into this discussion, because those two examples indicate how badly such a change would break existing python code outside the stdlib. I'm going to close this issue as rejected. The provision of a differently named builtin with the alternate semantics requested here could be raised on python-ideas, but I doubt it will get much traction since you can just do dir(xxx.__class__ for the rare cases where you want that info. Aside: I haven't looked at what jedi is, but perhaps you need to rethink your dependence on dir, just as we (may be?) rethinking inspect's dependence on dir. -- resolution: - rejected stage: - committed/rejected status: open - closed ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue19002 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue18844] allow weights in random.choice
Serhiy Storchaka added the comment: The proposed patch add two methods to the Random class and two module level functions: weighted_choice() and weighted_choice_generator(). weighted_choice(data) accepts either mapping or sequence and returns a key or index x with probability which is proportional to data[x]. If you need several elements with same distribution, use weighted_choice_generator(data) which returns an iterator which produces random keys or indices of the data. It is more faster than calling weighted_choice(data) repeatedly and is more flexible than generating a list of random values at specified size (as in NumPy). -- Added file: http://bugs.python.org/file31732/weighted_choice_generator.patch ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue18844 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
