[issue16991] Add OrderedDict written in C
Eric Snow added the comment: I figured out what I hope were the last memory-related issues. Apparently tp_traverse is not inherited if tp_flags is set. I had it set on all the view types and all the iterator types. So during GC it would blow up when it tried to call tp_traverse.

Can't we raise a nice error message when we get a socket, whereas the function does not support HANDLE?

[issue17913] stat.filemode returns - for sockets and unknown types
Richard Milne added the comment:
I've added some changes to the module which (I believe) not only fix this bug,
but add the reverse function, converting a permission string to a number.
The diff was made against Lib/stat.py @ 84234:f32dad3a243e, which was the most
recent version of the file I could find. My patch is intended for Python 2.7,
but should work on 3.3 (though I haven't tested it there).
My 'filemode' function ('mode2str') is not as short and elegant as the current
one, but then it should fix this bug, and it doesn't require duplicating so
many of the module's constants in a lookup table. It also includes a check to
make sure mode characters (like 'p', 's', '-', etc) are defined for every
numeric mode in the module... so long as their names start with the prefix
S_IF (... which may lead to conflicts with issue 17924).
I may also have gone beyond the scope, and added code to recognise the git link
file mode (see
http://stackoverflow.com/questions/737673/how-to-read-the-mode-field-of-git-ls-trees-output),
but this extension should be easy to recognise and remove.
Lastly, there are some minor whitespace and sorting changes (notably, S_IF*
defs sorted by mode num).
As for tests, I couldn't find any for this module in Lib/test. I have at least
included a command line test which exhaustively tests the encoding and decoding
of every valid file mode. If you want, I've even a test script which creates an
example of every valid file type (apart from socket and git link types), with
every valid file mode!

[issue17913] stat.filemode returns - for sockets and unknown types
Richard Milne added the comment: I already see my name change will cause problems. The tarfile.py (Lib/tarfile.py:277) module relies on the function being named 'filemode'. As the stat.filemode function is relatively new, I don't know how many other modules rely on it. I changed the name because I thought the new name (mode2str) better described what the function does, and is orthogonal to the reverse function (str2mode). But, of course, I've no issue with whatever the functions are finally named...

I have a version already written externally at https://code.google.com/p/importers/source/browse/importers/lazy.py. Part of the trick of making it work is having a way to drop the lazy mixin from the loader MRO for all future uses (which is important for reloads) is to assign __loader__ to super(Mixin, self). The problem is that if you use isinstance on that loader with any of the ABCs in importlib.abc it will always come back false no matter whether the interface is actually implemented or not. While I consider it a marginal thing for people to do (importlib.abc is for making sure people implement the right methods and providing default implementations, not for interface checking), I'm sure someone will do it and I would like one less possible warning in any future docs about this lazy mixin regarding isinstance checks. -- priority: normal - low ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue18275 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

I don't want the str() of IntEnum to return just the decimal string (e.g. 42), since that breaks half of the usefulness of using the enum in the first place -- people will write print(x) and be confused. Unfortunately the json module doesn't have a way to define *in the object* how to customize its serialization -- this is always done in the json encoder/decoder.

If we go the __protocol__ route we add one method to Enum which returns the `str` of its `.value`, and we're set for every Enum.* As a bonus, any other object that needs special json (or yaml or whatever) consideration has a fairly easy way to make it happen. *Every normal Enum, anyway. ;) -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue18264 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue18275] Make isinstance() work with super type instances
Brett Cannon added the comment: On Fri, Jun 21, 2013 at 11:11 AM, Antoine Pitrou rep...@bugs.python.orgwrote: Antoine Pitrou added the comment: I'm attracted to the idea of making a loader lazy by simply doing something like ``class LazySourceFileLoader(LazyMixin, SourceFileLoader): ...``. But then you have to make a specific Lazy subclass for each delegated loader implementation. With a proxy class you would simply proxy each loader instance: existing_loader = SourceFileLoader(...) lazy_loader = LazyLoader(existing_loader) ... But the point I tried to make earlier is that approach doesn't work directly when you are creating the loader instances dynamically within a finder. E.g. FileFinder ( http://docs.python.org/3/library/importlib.html#importlib.machinery.FileFinder) instantiates the loader for you. Now you could tweak things to make this work, but it isn't quite as straightforward as you suggest because of this need to have a callable for finders to use to create new loaders: class LazyProxy(importlib.abc.Loader): def __init__(self, loader): self.loader = loader def __call__(self, *args, **kwargs): self.args = args self.kwargs = kwargs return self def load_module(self, fullname): # XXX ignoring sys.modules details, e.g. if module already existed. lazy_module = LazyModule(fullname, proxy=self, name=fullname) sys.modules[fullname] = lazy_module return lazy_module class LazyModule(types.ModuleType): def __init__(*args, proxy, name, **kwargs): self.__proxy = proxy self.__name = name super().__init__(*args, **kwargs) def __getattribute__(self, attr): self.__class__ = Module state = self.__dict__.copy() loader = self.__proxy.loader(*self.proxy.args, **self.proxy.kwargs) # XXX ignoring sys.modules details, e.g. removing module on load failure. loader.load_module(self.__name) self.__dict__.update(state) return getattr(module, attr) That's all totally untested (not even verified to compile) but I think that would do what you are suggesting. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue18275 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue18217] Deprecate and remove gettext.install
Terry J. Reedy added the comment: The rationale for install is For convenience, you want the _() function to be installed in Python’s builtins namespace, so it is easily accessible in all modules of your application. As David noted, this also make it easy to update _ in just one place when a new language is selected. Alex disagrees and would like to break any code that uses install, which I thing is much code, by removing it. This would force writers to do something else that will be *much* more work and which might make code harder to read. We do not do this without much greater reason than Alex has given. I think this a bad deprecation proposal and should be rejected. I also think the idea should have been posted to python-ideas first. I do think that this should become a doc issue to clarify the meaning and usage of install. The link Alex gave was to NullTranslations.install. The module install function itself is at http://hg.python.org/cpython/file/01da7bf11ca1/Lib/gettext.py#l424 The doc for install could be much improved to say what it actually does. Pass *domain*, *localedir*, fallback=True, and *codeset* to translation, which returns translation instance t. Pass *names* to t.install. The default install method, NullTranslations.install link, which is inherited by GNUTranslations link, installs t.gettext in builtins as _. See the description of translation and NullTranslations.install for the meaning of the parameters. + rationale quoted above This expanded doc would make it clearer that one can write a custom subclass of NullTranslations with a custom .install method that would do something different, such as bind _ to a dynamic (indirect) gettext, whether in builtins or in a project module that is explicitly imported by every module that needs it. The doc for NullTranslations.install needs the erroneous '()'s removed to make clear that the bindings are to bound methods and not the result of calls to bound methods. Ie, self.gettest() should be just self.gettext. -- nosy: +terry.reedy type: - enhancement versions: +Python 3.4 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue18217 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue18219] csv.DictWriter is slow when writing files with large number of columns
Terry J. Reedy added the comment: What is the purpose in touching fieldnames, either in tuple-izing it or in making it private and wrapped with a property. If someone wants to modify it, that is up to them. In any case, this change is not germane to the issue and could break code, so I would not make it. wrong_fields could be calculated with any(k for k in rowdict if k not in self._fieldset) to stop on the first extra, if any. That said, in 3.x, replacing wrong_fields = long expression if wrong_fields: with if rowdict.keys() - self._fieldset: should be even faster because the iteration, which will nearly always go to completion, is entirely in C (or whatever). Does test/text_cvs have tests for DictWriter, both with and without rowdict errors? If so, or if added, I would be willing to commit a patch that simply added ._fieldset and used it as above for a set difference.

[issue18220] Expand itertools.islice docstring signature to 2 lines
Terry J. Reedy added the comment:
The problem with all of range, slice, and islice is that
[start,] stop [, step] is an impossible signature and needed to be changed.
The actual signature is
start_or_stop, [stop, [step]]
with customized processing to interpret start_or_stop according to the presence
of stop (which is not really optional). We suggestion to doc it this was
rejected as equally confusing.
In 3.3, we decided to stop trying to force all signatures presented to the user
into one line and instead use multiple lines to present what are multiple
signatures from a user view. So this alternative was used for range and slice
(and other functions).
For islice, the islice entry has
itertools.islice(iterable, stop)
itertools.islice(iterable, start, stop[, step])
Py.user is corrrect in suggesting the same change for islice docstring. I have
changed the title to be clearer.
The itertools function table has
islice()seq, [start,] stop [, step] elements from ...
I thing this should be changed also. A new line for arguments 'seq, stop' would
say
'elements from seq[0:stop]' example 'islice('ABCDEFG', 2) -- A B
Then remove brackets from [start] in the current line.
Py.user: To accept non-trival patches (typos, grammar corrections are trivial)
we need a signed contributor agreement
http://www.python.org/psf/contrib/ and
http://www.python.org/psf/contrib/contrib-form/ new electronic form
An '*' will appear after your name here when it is processed.
I presume this will need a real (legal) name on the form, even though not in

[issue18236] int() and float() do not accept strings with trailing separators
Terry J. Reedy added the comment:
You stated facts: what is your proposal?
The fact that unicode calls characters 'space' does not make then whitespace as
commonly understood, or as defined by C, or even as defined by the Unicode
database. Unicode apparently has a WSpace property. According to the table in
https://en.wikipedia.org/wiki/Whitespace_%28computer_science%29
1C - 1F are not included by that definition either. For ascii chars, that table
matches the C definition, with \r included.
So I think your implied proposal to treat them as whitespace (in strings but
not bytes) should be rejected as invalid. For 3.x, the manual should specify
that it follows the C definition of 'whitespace' (\r included) for bytes and
the extended unicode definition for strings.

[issue18277] Queue is empty right after put from the same process/thread
shwouchk added the comment: The major difference with the issue you referenced is that the behavior in #17985 is clearly stated and warned against in the docs (Queue.Empty being inconsistent with Queue.size), whereas this is not. As for the actual behavior problem: Imagine you build an abstraction atop Queue (For example and specifically, a queue iterator). This iterator might return None or a similar sentinel if there is nothing on the queue. Since you find the construct useful and would like to keep uniformity in the program, there is a place you use this abstraction in a fairly tight loop to pass messages from one part of the program to another part, in the same process and thread. Now the logic of the program does not work correctly as it was based on the assumption that in a single process Queue would work as expected. The problem is not the exception but with having an abstraction built atop Queue that works right with respect to program logic both when you use it in one thread and in multiple ones. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue18277 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue18277] Queue is empty right after put from the same process/thread
Richard Oudkerk added the comment: Why would you use a multi-process queue to pass messages from one part of the program to another part, in the same process and thread? Why not just use a deque? Is this something you actually did, or are you just trying to come up with a plausible example? And, of course, if you are sure there must be an item available, you could just use get() instead of get_nowait(). -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue18277 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue18277] Queue is empty right after put from the same process/thread
shwouchk added the comment: Richard, I think you missed my point. First, yes I did do that. Second (the point): I did this to use the same abstraction that was used extensively for other purposes, instead of recreating the same abstraction with a deque as its basis. Component reusability is one of the main points of OOP, after all... And no, an item is not necessarily available - sometimes there is a message and sometimes there isn't. But if one was put into the queue, I claim that I should be able to rely on it being available right away in the application logic. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue18277 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue18279] IDLE Unit test for RstripExtension.py
Terry J. Reedy added the comment:
There is a separate issue about killing that warning.
If you leave off '-ugui', you will see the traceback and why I said that
requires('gui') should be wrapped for unittest discovery. As the code is, the
call is executed when the file is imported, possibly during discovery, before
the unittest or regrtest runner starts running tests and counting success,
fail, skip.
Two other thoughts before I look as rstrip and the content of the new test
file.
I would like to just call it test_rstrip.
I have thought of having just one mock_idle.py for mock Idle classes (as
opposed to mock_tk with mock tk classes. I am not sure how many will will need.
Since your mock_ewin uses a real tk.Text widget, hence requiring gui, what is
its purpose? The point of the mock_tk classes is to avoid gui and make the test
text only. I am not saying that this is the only purpose, but other purposes
should be stated and documented.

[issue18279] IDLE Unit test for RstripExtension.py
Phil Webster added the comment:
Thank you for the feedback Terry. I'm not seeing the traceback without '-ugui'
either, so I'm going to look into that. I get the same results with
requires('gui') moved inside of setUp, is that what you mean by wrapping?
For mock_ewin I used a real Text widget because RstripExtension uses index(),
get(), and delete() and I was not able to figure out how the widget implemented
these (is there a single string with the contents?). I can work on a non-gui
test though if that's what needs to be done.
Thanks!
