Neil Girdhar added the comment:

Just updated the "what's new".  Also, thank you for adding my name to 
Misc/Acks.  Should we also add Joshua Landau's name?  He helped me quite a bit 
with the implementation, and he wrote the PEP.

Unless you intend to support compiling with vs2010 after 3.5 is released, and 
from the devguide and your comment I presume not, then with beta nearing, I 
would agree that we should be testing 2015 builds.

[issue24186] OpenSSL causes buffer overrun exception

[Steve Dower]

New submission from Steve Dower:

There is an issue where an optimised OpenSSL function causes a buffer overrun 
in 64-bit Windows builds and terminates the process (this is why the buildbots 
aren't getting very far right now).

I suspect it may be a compiler issue, but for now I'm disabling the optimised 
function. This issue is a reminder to myself to re-enable the function when we 
have a fix. I'll follow up with the compiler team and possibly the OpenSSL team 
separately.

[issue23995] msvcrt could not be imported

[Steve Dower]

Steve Dower added the comment:

I wouldn't have thought so, since the IO stack is entirely portable, at least 
from the Python side of things. This would have to have been a test that 
somehow knows about optional functions and notifies you if they're missing but 
without failing the run. I don't think that's feasible, at least in this case, 
since there's no way to know that the function should be there.

Potentially we could set up a test to ensure that we don't remove public 
functions by dumping a complete list, but that's beyond the scope of this one 
issue.

[issue24185] Add Function for Sending File to Trash (or Recycling Bin)

[Taylor Marks]

New submission from Taylor Marks:

When you have a file that you don't think you need anymore, the proper thing to 
do with it is move it to the Trash (or Recycling Bin, if you're on Windows.)

The standard library, however, doesn't offer any way of doing this currently. 
Instead, the only thing it offers is the ability to delete files. Deleting 
files is a potentially dangerous operation. A novice programmer may end up 
carelessly delete the wrong file.

I would suggest adding in a new function which allows for cross-platform moving 
of files to trash. It could go into the existing shutil or os modules. Or it 
could get its own module (like glob).

It could be based upon (or even be exactly) this implementation:
https://pypi.python.org/pypi/Send2Trash
https://github.com/hsoft/send2trash

Afterwards, the docs for os.remove and shutil.rmtree could have a warning added 
that suggests that instead of using such dangerous functions, it may be best 
for the user to use the new function.

(If this is not the place to propose additions to the standard library, please 
redirect me for where I should go instead. PEP 5 covers how the language should 
evolve, but then only has a link to bugs.python.org.)

[issue22027] RFC 6531 (SMTPUTF8) support in smtplib

[R. David Murray]

R. David Murray added the comment:

Coming back to this, I noticed a number of things wrong with the logic that I'm 
not sure how I missed before.  I had to rewrite pretty much all of the logic.  
The good news is the patch is now smaller :)

The new tests are failing, because they are wrong: the msg argument to 
sendmail/mail *must* be a byte string if smtputf8 is in effect, since an email 
message may contain multiple encodings as well as other binary data.  (Well, 
the msg argument could be an ascii string, but what would be the point?)

I'm uploading this without fixing the tests because I'm out of time for now and 
may not get back to it before the weekend.  Perhaps someone else will have time 
to work on the tests before then.

[issue24183] ABCMeta classes do not support the **kwargs standard class interface

[Timothy Cardenas]

Timothy Cardenas added the comment:

Ahhh i see now. 

Even the simple case "class Foo(bar='baz'): pass" fails.

I misunderstood the documentation then. I thought that python 3 introduced a 
new interface for all classes when it actually just introduced the option to 
add keyword arguments to your own metaclasses but didn't alter the base level 
class interface.

I wanted a bit more background around the object.__init__ and found this 
ticket: http://bugs.python.org/issue1683368. While this is probably not the 
only place where this comes up I see the tact that the python core team took 
and understand your reference more completely now.

I thank both of you for your help and quick responses.

[issue2704] IDLE: Patch to make PyShell behave more like a Terminal interface

The changes I proposed would not have to be extensions, as they are basically

conditional. I will experiment with using prefix-up/down in one of my installed 
pythons.

[issue2704] IDLE: Patch to make PyShell behave more like a Terminal interface

[Terry J. Reedy]

Terry J. Reedy added the comment:

The PyShell patch does two things that I want to consider separately, and 
carefully, along with other possible solutions to the perceived problems.

1. Go to end-of-file when entering a letter or number in a read-only text area. 
In msg110889 Tal says "Note that not only letter/number keys should be passed 
on." I see the point, but expanding the set seems to me a complication and a 
move in the wrong direction.  Doing nothing, or maybe beeping, is a normal 
response to entry in a read-only area. Regardless of what I wrote before, I am 
not completely comfortable with adding magical behavior.

The fixed key-binding for goto-file-end is cntl-end (command-end). I propose 
adding  as a synonym. Currently, it sometimes opens a completion box even 
in read-only areas, where it is useless and annoying. This should be changed 
anyway, and having it cause the cursor to jump to me seems to fit with its 
indent behavior.

2. Make  and  do double duty to both traverse statements in the 
history and lines within the current statement.  However, the complicated rules 
to juggle two roles, in msg68299, make my head hurt. I would rather use Shift-, 
cntl-, or alt- up/down instead.

The fundamental issue, touched on by Cherniavsky Beni in msg67706, is that 
Python is not a command-line language. It is a statement language. It does not 
fit well in a command-line terminal where history consists of lines rather than 
statements. PyShell is a statement terminal designed to fit Python, not a line 
terminal.

I appreciate this *much* better than 7 years ago.  When I wrote msg66119, I 
probably was not aware of being able to retrieve statements with Alt-P.

[issue24183] ABCMeta classes do not support the **kwargs standard class interface

[R. David Murray]

R. David Murray added the comment:

Yes, this is exactly analogous to object.__init__ not accepting arguments, but 
subclasses being free to do so.  ABCMeta *does* adopt the contract.  keyword 
arguments to the class constructor are not accepted unless you write a meta 
class that accepts them.  Period.  (That is, "class Foo(bar='baz'): pass" 
fails.)

No, it would not be technically correct.  For the same reason, object.__init__

[issue24183] ABCMeta classes do not support the **kwargs standard class interface

[Timothy Cardenas]

Timothy Cardenas added the comment:

Hmm Ok. You are right i can do the following:

from collections import UserDict
from abc import ABCMeta


class MetaMyDict(ABCMeta):

@classmethod
def __prepare__(cls, name, bases, **kwargs):
return {}

def __new__(mcls, name, bases, namespace, **kwds):
return super().__new__(mcls, name, bases, namespace)

def __init__(cls, name, bases, namespace, **kargs):
return super().__init__(name, bases, namespace)

class MyDict(UserDict, metaclass=MetaMyDict, bar='baz'):
pass

dictionary = MyDict()

But I guess i would have expected a core lib library to be consistent with the 
data model 
https://docs.python.org/3.4/reference/datamodel.html#preparing-the-class-namespace.
 As it stands an end user can't get a subclass of ABCMeta to work with the same 
**kwargs interface without creating a custom metaclass that strips it out 
before passing to ABCMeta. 

Wouldn't it be much easier and technically correct for the core ABCMeta library 
to adopt the same interface contract for class creation introduced in python3?

[issue24181] test_fileio crash, 3.5, Win 7

[Steve Dower]

Steve Dower added the comment:

It's entirely possible that I missed a _PyVerify_fd call around the ftruncate 
implementation, since that function is now a no-op for VS 2015 builds. The only 
reason I didn't remove them all when adding the new handling for was because 
there was no trustworthy version of VC14 around then (it was still Preview).

VS 2015 RC is trustworthy, so it is time to upgrade, but I'm still not quite 
ready to aggressively break everyone who hasn't. Maybe we should?

which is now in RC.  As recently as this morning, I've had a clean test run
with 2015 Community Edition on Windows 8.1.

[issue23699] Add a macro to ease writing rich comparisons

[Raymond Hettinger]

Raymond Hettinger added the comment:

I'm -1 on this whole concept and I don't believe that it will make porting 
easier.  It takes longer to learn the macro, see what it does, write tests for 
it, etc than it takes to model ten lines of boilerplate code.

The macros make it harder for me and others to understand and maintain the 
code.  In this regard, Python has been getting worse (harder for new 
maintainers to look at code and know what it is doing).   Saving ten lines of 
clear code isn't a good motivation for going down this path.   C macros are 
infamous for a reason.

[issue23699] Add a macro to ease writing rich comparisons

[Petr Viktorin]

Petr Viktorin added the comment:

Is it really not better to give the operation a name, rather than repeating the 
same ten lines every time? (Well, not the same -- all the modules code it a bit 
differently, but with the same meaning.)

I might be true that the types in Python itself are "done", but this is 
intended as part of the C API. There are still modules unported to Python 3, 
for which *now* is the beginning.

I think this may in fact be a bug.  There are other places in the socket module 
where port is checked, create_connection() just seems to have been missed.

create_connection() and socket.connect() have different behavior:

>>> socket.socket().connect( ('google.com', 0x1 + 80) )
Traceback (most recent call last):

FWIW, I prefer the current form so that I don't have to constantly lookup to

If this has been around from the beginning, it might have "eased" the writing

That doesn't matter.  The minimum dict size is 8.

> Why not write Py_SIZE(seq) * 3 / 2?

Because I prefer the / 2 * 3 style so I don't have to think about whether seq 
can overflow.  Do you really feel like bike-shedding this?

[issue24177] Add https?_proxy support to http.client

[Demian Brecht]

New submission from Demian Brecht:

http_proxy and https_proxy are common environment variables used cross 
platform. Currently, urllib.request has support for it, but http.client does 
not. It probably should.

If support is added to http.client, the handling of proxy environment variables 
in urllib.request should be factored out and made to be reliant on the changes 
in http.client (which shouldn't require any new code, only removal).

Given the common usage of the environment variables (as observed by other 
utilities such as wget and curl), it seems odd to require a user to know about 
and use the higher level urllib.request API rather than have support for it 
baked into the lower level http.client API.

Eric, is there any chance this can land in 3.5?  OrderedDict is a heavily used

imperfect (but fully compatible with existing OrderedDict) implementation in 
3.5.  We can optimize it in 3.6.

- It needs to be a macro, not function, to support various types (unsigned long 
long, float; possibly C++ stuff with overriden operators)

- Another suggestion to change the order of arguments; I still think being the 
same as richcmp and PyObject_RichCompareBool is best.

I believe all the issues raised here and on the list are handled. Could anyone 
re-review the patch?
If the usage changes are too much, it's possible to only change 
Include/object.h and Doc/c-api/typeobj.rst, and leave the rest. Should I trim 
the patch that way?

Anything else I can do to help this get merged?

[issue5633] fix for timeit when the statement is a string and the setup is not (and tests)

[Serhiy Storchaka]

Serhiy Storchaka added the comment:

Here is more complicated patch, that not only fixes handling of callable setup, 
but also simplifies the implementation of timeit constructor.

[issue11145] '%o' % user-defined instance

[Ethan Furman]

Ethan Furman added the comment:

Armin indicated in his last comment that the patch still has multiple issues.

Are there tests to catch the issues he previously found?  That seems the best 
method to verify that the current (and future) patches don't break 2.7.

[issue24176] Incorrect parsing of unpacked expressions in call

[Thomas Caswell]

New submission from Thomas Caswell:

On the current tip (changeset: 96023:4b5461dcd190) the following results in a 
syntax error

def test(a='a', b='b'):
print(a, b)

opta = dict()
optb = dict(a=1, b=2)
test(**(opta or {}))  # <- works on all python
test(**optb or {})# <- fails on current hg tip


This is suspected to be a result of 
https://hg.python.org/cpython/rev/a65f685ba8c0 

This was reported as an issue against sphinx 
(https://github.com/sphinx-doc/sphinx/pull/1889) and I was redirected here.

As suggested by Robert Lehmann suggests the issue is 
https://hg.python.org/cpython/rev/a65f685ba8c0#l1.33 which should be `** test`. 
 Making this change prevents the syntax error (patch attached).

[issue5633] fix for timeit when the statement is a string and the setup is not (and tests)

[Serhiy Storchaka]

Serhiy Storchaka added the comment:

Definitely there is a bug. The code of timeit is written to support string stmt 
and callable setup. Expected that locals available when the function is 
created, would be available when the function is executed. But this doesn't 
work. May be it worked in the earlier Python, I don't know. Due to the lack of 
tests this was unnoticed.

Here is simpler patch that fixes the support of callable setup with string stmt.

But I like Tim's approach (compile testing function using the single template), 
it makes the implementation simpler. I'll try to adapt it for current sources.
