[issue18352] collections.Counter with added attributes are not deepcopied properly.

[Vajrasky Kok]

Vajrasky Kok added the comment:

The question is whether we should give the freedom to user to add dynamic 
attribute to Counter object.

Is this freedom has any practicality? Why do we want to add dynamic attributes 
to Counter object?

Decimal object does not have this freedom.

>>> from decimal import Decimal
>>> z = Decimal('1.0')
>>> z.foo = 'a'
Traceback (most recent call last):
  File "", line 1, in 
AttributeError: 'decimal.Decimal' object has no attribute 'foo'

Actually I am not really sure about this. Maybe someone knows the answer.

[issue18421] Refactor call_with_frame() function of pyexpat.c

[STINNER Victor]

New submission from STINNER Victor:

Modules/pyexpat.c contains a call_with_frame() function which uses many 
low-level attributes like tstate->c_profilefunc. I don't think that pyexpat.c 
is the best place for such function, it should be moved to Python/ceval.c.

Except the call to XML_StopParser(self->itself, XML_FALSE); on failure, the 
code doesn't look to be specific to (py)expat.

[issue15792] Fix compiler options for x64 builds on Windows

[Jeremy Kloth]

Jeremy Kloth added the comment:

Just to note that, as it stands, these wrongly assigned options account for 28 
of the 216 warnings (or 13%) currently emitted.  This is just one easy step 
towards a warning-free 64-bit Windows build.

It would be nice to get Win64 to be one of the warning-free platforms (see 
msg63893 of issue1616).

[issue18422] is_package missing so can't use -m

[Brett Cannon]

Brett Cannon added the comment:

The solution from issue #18058 can't be backported because it would expose a 
new public API on the NamespaceLoader class. It would also introduce new 
functionality which would differ between Python 3.3.2 and Python 3.3.3 which 
can't really be classified as a bugfix since it's new functionality that didn't 
exist previously.

You're also not losing any abilities by not having this in Python 3.3. All it 
means is that the status quo holds compared to Python 3.2 in that normal 
packages are the only way to execute a package with __main__ defined, while 
Python 3.4 gains the ability to also support namespace packages.

Because of all of these points, I'm closing this issue as rejected (sorry; I 
know it would be handy to have but I just can't justify it).

[issue18424] sum() does not return only the sum of a sequence of numbers + PEP8 reccomandation

[Marco Buttu]

New submission from Marco Buttu:

The documentaion of sum():

Returns the sum of a sequence of numbers (NOT strings) plus the 
value of parameter 'start' (which defaults to 0).  
When the sequence is empty, returns start.

A. According to the PEP-8 it should be: "Return the sum...", and
   "When the sequence is empty, return start.", like the other docs. 
   For instance:

   >>> print(len.__doc__)
   len(object) -> integer

   Return the number of items of a sequence or mapping.

B. When the second argument is a tuple or a list, you can add sequences
   of sequences:

   >>> sum([['a', 'b', 'c'], [4]], [])
   ['a', 'b', 'c', 4]
   >>> sum(((1, 2, 3), (1,)), (1,))
   (1, 1, 2, 3, 1)

C. sum() takes not just sequences:

   >>> sum({1: 'one', 2: 'two'})
   3

Maybe it is not a good idea to give a complete description of sum() in the 
docstring, but perhaps something "good enough". In any case, I think the lack 
of the PEP-8 recommendation should be fixed.

[issue18407] Fix compiler warnings in pythoncore for Win64

[Jeremy Kloth]

Jeremy Kloth added the comment:

Added new patch that removes the duplicate changes from issue #15792 and 
comments the lone explicit cast.

These changes fix 116 of the 216 warnings (54%!) for Win64.  Together with 
issue #15792 brings the remaining count to 72.

I am unsure if splitting the changes further makes much sense as guidance I 
have received on IRC and as others have noted in various bug reports about 
"spamming" the tracker with issues per file.

With that and MvL's comment in issue #18295, I do not think that it is 
advisable to separate out changes for that issue.

[issue18424] sum() does not return only the sum of a sequence of numbers + PEP8 reccomandation

[R. David Murray]

R. David Murray added the comment:

Perhaps we could add something like "Also works, though possibly inefficiently, 
on any iterable whose elements support addition".  The biggest part of the 
sphinx docs for this are about what to use instead, and that doesn't really 
seem appropriate for a docstring.  So it may indeed be best to just not mention 
it in the docstring.

[issue18424] sum() does not return only the sum of a sequence of numbers + PEP8 reccomandation

[Ronald Oussoren]

Ronald Oussoren added the comment:

There's an annoyingly long discussion about sum() on python-ideas.

IMHO the documentation should mention, as it does now, that sum is intended to 
be used with a sequence of numbers even it does work with most objects that 
support the + operator (such as by implementing __add__). In particular, using 
sum with a sequence of lists or tuples is extremely inefficient.

The fact that sum({1:'a', 2: 'b'}) works is a side effect of the how python 
works with sequences and IMHO doesn't have to be documented in every function 
that accepts a sequence as an argument.

[issue18417] urlopen() has a hidden default for its timeout argument

Barry A. Warsaw added the comment:

I'm not sure I completely understand the arguments in #14425 and #2451 which
it refers to.  I could be wrong, but it seems to me that these are arguing
against using socket.getdefaulttimeout() in favor of the magic non-public
attribute that's currently being used.  While I don't like that particular
aspect, it's not the real point of *this* bug.

Even if socket._GLOBAL_DEFAULT_TIMEOUT is the effective default for `timeout`,
I still think using that as the default value for the keyword argument is
wrong, both for usability of this API and for the documentation of it.

I don't see why `timeout=None` wouldn't be acceptable, but let's assume it
isn't.  A documented, public sentinel would be acceptable and it could either
be defined as:

DEFAULT_TIMEOUT = object()

or

DEFAULT_TIMEOUT = socket._GLOBAL_DEFAULT_TIMEOUT

With the latter, the function's signature would then change to:

def urlopen(url, data=None, timeout=DEFAULT_TIMEOUT, ...)

and nothing functional would change.  The documentation update would be much
more helpful too.  If it weren't for the new module attribute, it could
probably even be backported.

Then users of this module could do something like this:

from urllib.request import DEFAULT_TIMEOUT, urlopen

def my_open(url, timeout=None):
my_timeout = DEFAULT_TIMEOUT if timeout is None else timeout
return urlopen(url, timeout=my_timeout)

[issue18417] urlopen() has a hidden default for its timeout argument

[R. David Murray]

R. David Murray added the comment:

OK, I reviewed the issue enough to remember:  If socket.setdefaulttimeout is 
never called, then the default timeout is None (no timeout).  Since 
socket.setdefaulttimeout is deprecated, the global default should always be 
None.  Therefore, if you want to use the "default" timeout in a new 
application, you could pass None as the value for timeout...but of course that 
probably doesn't do what you want.  What you *really* want to do is pass the 
default timeout value being used by your application, whatever that is, managed 
however your application/library manages it.

If you are writing a library that for some reason wants to retain backward 
compatibility with setdefaulttimeout (and I think you probably shouldn't be), 
you could call getdefaulttimeout to get the current default value.  Since 
urlopen is creating a new socket object, this should have the correct semantics.

Mind, I don't claim that there can't be a better solution, I'm just trying to 
explain the current state of affairs as I understand it.  However, aside from 
the ugliness of the current signature for urlopen, at the moment it seems 
reasonable to me :)

That said, this argument is premised firmly on setdefaulttimeout being 
deprecated, and there is currently no indication of that in its documentation 
that I can see.

[issue18352] collections.Counter with added attributes are not deepcopied properly.

[Olivier Gagnon]

Olivier Gagnon added the comment:

The dictionary and the set do not give the freedom to add dynamic attributes to 
them. I agree that the Counter should have the same behaviour.

However, this will raise the same bug when we inherit from a Counter object.

>>> class mylist(list): pass
... 
>>> l = mylist()
>>> l.foo = "bar"
>>> c = copy.deepcopy(l)
>>> print(c.foo) # prints bar

>>> class myCounter(Counter): pass
... 
>>> original = myCounter()
>>> original.foo = "bar"
>>> c = copy.deepcopy(original)
>>> c.foo
Traceback (most recent call last):
  File "", line 1, in 
AttributeError: 'myCounter' object has no attribute 'foo'

The reduction function should still copy every dynamic attribute of the object.

[issue18424] sum() does not return only the sum of a sequence of numbers + PEP8 reccomandation

[Ezio Melotti]

Ezio Melotti added the comment:

Currently sum() is intended to work with numbers, explicitly forbids strings 
(as noted in the docstring), but also works with other types (even though it's 
inefficient).

If we want to document this, a possible wording might be:
Returns the sum of a sequence of numbers plus the 
value of parameter 'start' (which defaults to 0).  
When the sequence is empty, returns start.
Using sum() with a sequence of strings is not allowed,
and might be inefficient with sequences of other types.

We should also consider that the implementation/behavior might change in 
future, but we can always update the docstring again.

+1 on the PEP 8 changes.

[issue18416] Move to absolute file paths for module.__file__

[Ronald Oussoren]

Ronald Oussoren added the comment:

Isn't this because the first entry of sys.path is '' when python is started 
without a script? All other paths on sys.path are already absolute paths 
(tested with a relative path in $PYTHONPATH).

If that's correct, just adding os.getcwd() instead of '' as the first entry of 
sys.path would fix this issue, and would also make sure that imports of modules 
next to the script keep working when the script uses os.chdir.

The disadvantage is that some users might depend on the current behavior :-(

[Marco Buttu]

Marco Buttu added the comment:

By reading the Ronald's comment, I realized it is better to keep it simple, so 
I agree with him.

The "extremely inefficient" reason seems to be less important (Python 3.3):

$ python -m timeit -s "a=['a']*1; b=['b']*1; a+b"
1 loops, best of 3: 0.00831 usec per loop
$ python -m timeit -s "a=['a']*1; b=['b']*1; sum([a, b], [])"
1 loops, best of 3: 0.0087 usec per loop

[issue18424] sum() does not return only the sum of a sequence of numbers + PEP8 reccomandation

[Ronald Oussoren]

Ronald Oussoren added the comment:

Appending a sequence of lists with sum is inefficient because it (currently) 
does a lot of copying, and that gets noticable when you sum a larger number of 
lists

Note how using sum for add 200 lists is more than twice as long as adding 100 
lists:

ronald@gondolin[0]$ python -m timeit -s "lists=[['a']*100 for i in range(100)]" 
"sum(lists, [])"
100 loops, best of 3: 2.04 msec per loop


ronald@gondolin[0]$ python -m timeit -s "lists=[['a']*100 for i in range(200)]" 
"sum(lists, [])"
100 loops, best of 3: 9.2 msec per loop


Also note how using itertools.chain is both a lot faster and behaves better:

ronald@gondolin[0]$ python -m timeit -s "import itertools; lists=[['a']*100 for 
i in range(100)]" "list(itertools.chain.from_iterable(lists))"
1 loops, best of 3: 165 usec per loop


ronald@gondolin[0]$ python -m timeit -s "import itertools; lists=[['a']*100 for 
i in range(100)]" "list(itertools.chain.from_iterable(lists))"
1 loops, best of 3: 155 usec per loop

(I used python2.7 for this, the same behavior can be seem with python 3).

See also #18305, which proposed a small change to how sum works which would fix 
the performance problems for summing a sequence of lists (before going too far 
and proposing to add special-case tuples and string)

[issue18378] locale.getdefaultlocale() fails on Mac OS X with default language set to English

[Dmitry Jemerov]

Dmitry Jemerov added the comment:

I personally don't, but the function is used by Sphinx, which is what I was 
trying to get to work when I ran into this problem.

[issue18324] set_payload does not handle binary payloads correctly

[R. David Murray]

R. David Murray added the comment:

Thanks, but the patch is incorrect.  The model consistently stores its data as 
surrogateescaped strings, and this assumption is baked in to other parts of the 
code.  So the correct fix is to do the surrogateescape encoding at the time the 
payload is set.

It might in fact be better to store a binary payload as binary, but making that 
kind of change to the model requires much more extensive review and testing.

[issue18378] locale.getdefaultlocale() fails on Mac OS X with default language set to English

[Martin v . Löwis]

Martin v. Löwis added the comment:

FWIW, I couldn't find any use of getdefaultlocale in any of the hg revisions 
(using hg grep) in

https://bitbucket.org/birkenfeld/sphinx/

Instead, it's (probably) docutils, which has this code:

locale_encoding = locale.getlocale()[1] or locale.getdefaultlocale()[1]
# locale.getpreferredencoding([do_setlocale=True|False])
# has side-effects | might return a wrong guess.
# (cf. Update 1 in 
http://stackoverflow.com/questions/4082645/using-python-2-xs-locale-module-to-format-numbers-and-currency)

I find that quite unfortunate, since locale.getpreferredencoding() would have 
don the right thing (IMO).

[issue18324] set_payload does not handle binary payloads correctly

[R. David Murray]

R. David Murray added the comment:

If you want to work on it that would be great.  Note that one of the things 
that is needed is a bunch more tests of setting various *kinds* of binary 
payload, including ones containing non-ascii data, and making sure the right 
thing happens when the payload is later fetched/serialized.

[issue18416] Move to absolute file paths for module.__file__

[Brett Cannon]

Brett Cannon added the comment:

That's exactly why it currently happens. What I would do is change importlib to 
just associate '' with os.getcwd() in FileFinder. That locks down where the 
module was found to an absolute path while still allowing '' to function as the 
cwd and be dynamically calculated.

[R. David Murray]

R. David Murray added the comment:

I played around with this for a bit, but I couldn't come up with any test 
improvements, or any way to test the bug that is being fixed.  So I just 
committed it as is.  Thanks, Serhiy.  And thanks Vajrasky for giving it a try 
and figuring out some of the stuff that *doesn't* work as a fix :)

I decided to only commit this to 3.4.  I don't think the risk of an unexpected 
behavior change in a maintenance release is worth the relatively small benefit 
that this fix provides.

I got it!  None of these alone actually worked.  But it lead me to get

that worked were getting this:

then I disabled my antivirus and User Account Control in windows 7. I'll 
bet it was just disabling the UAC that did it though.  I will find out 
later.  I need to get back to class now that I have what I need.  Thank 
you so much.  If you do need more info or help, please feel free to ask!

Continuing the IDLE unittest framework #15392, unit test for IdleHistory.py. 
This test depends on mockText and uses the patch by Terry at issue #18365.
Because the mockText is still about to commit, first patch 
http://bugs.python.org/file30865/mock_text2.diff and then use 
test_idlehistory.patch to run test_idlehistory. 
Once the mock Text get committed I will improve the patch according to.

in case anyone else ends up here through google...

the problem described here is not related to the linked issue.  it was just a 
missing `__init__.py` in the module (plus sucky error messages).

the following works fine:

[issue10984] argparse add_mutually_exclusive_group should accept existing arguments to register conflicts

[paul j3]

paul j3 added the comment:

One usage option is to make a subclass of HelpFormatter (the accepted way of 
customizing a formatter), and write a function that formats each group 
independently.  For the example case, the resulting format might be:

   usage: PROG [-h] [-b] [-a | -c] [-a | -d]

-h and -b are not part of any group.  These are followed by the two groups.  -a 
is repeated because it appears in both groups.

[issue18426] Crash when extension does not use PyModule_Create()

[Ivan Johansen]

New submission from Ivan Johansen:

In Python/importdl.c around line 99 in the function 
_PyImport_LoadDynamicModule() you can find the code:
  def = PyModule_GetDef(m);
  def->m_base.m_init = p;

If the module m, which is returned from a newly imported extension, is not 
created by PyModule_Create() but in some other way then PyModule_GetDef(m) will 
return NULL. The next line will then dereference a NULL pointer and crash. 

I suggest a check for this is added:
  def = PyModule_GetDef(m);
  if(def != NULL) 
def->m_base.m_init = p;
