[issue21611] int() docstring - unclear what number is

[eryksun]

eryksun added the comment:

The constructor tries __trunc__ (truncate toward 0) if __int__ isn't defined. 
If __trunc__ doesn't return an instance of int, it calls the intermediate 
result's __int__ method. In terms of the numbers ABCs, numbers.Real requires 
__trunc__, which should return a numbers.Integral, which requires __int__. 

The special methods __trunc__, __floor__, and __ceil__ aren't documented in the 
language reference. They're mentioned briefly in the docs for the math 
functions trunc, floor, and ceil.

[issue19997] imghdr.what doesn't accept bytes paths

[Claudiu.Popa]

Claudiu.Popa added the comment:

There are other modules with support for bytes filenames in their API:

bz2  
codecs   
gzip 
lzma 
pipes.Template   
tarfile
tokenize
fileinput
filecmp
sndhdr
configparser

Also, given the fact that sndhdr supports them and its purpose is similar with 
imghdr, it would be a surprise
for a beginner to find out that imghdr.what(b"img") is not working, while 
sndhdr.what(b"snd") works.

[issue21401] python2 -3 does not warn about str/unicode to bytes conversions and comparisons

[STINNER Victor]

STINNER Victor added the comment:

Serhiy wrote:
"I think that even if we accept this change (I am unsure in this), a warning 
should be raised only when bytes and unicode objects are equal. When they are 
not equal, a warning should not be raised, because this matches Python 3 
behavior."

Python 3 warns even if strings are equal.

$ python3 -b -Wd
Python 3.3.2 (default, Mar  5 2014, 08:21:05) 
e" for more information.
>>> b'abc' == 'abc'
__main__:1: BytesWarning: Comparison between bytes and string
False
>>> b'abc' == 'abc'
False

The warning is not repeat in the interactive interprter because it is emited 
twice at the same location "__main__:1".

[issue21634] Pystone uses floats

[Lennart Regebro]

New submission from Lennart Regebro:

Pystone uses some floats in Python 3, while in Python 2 it's all integers. And 
since it is, as far as I can tell, based on Dhrystone, it should be all ints.

After fixing the division in the loop to be a floor division it runs the same 
as in Python 2. I've verified that after the attached fix the only floats 
created are time stamps, so this seems to be all that's needed.

This also makes the benchmark run c:a 5% faster, lessening the speed difference 
in pystone between Python 2 and Python 3, which contributes to the 
misconception that Python 3 is horribly slow.

[issue21634] Pystone uses floats

[STINNER Victor]

STINNER Victor added the comment:

According to the name of variables ("IntLoc2 = IntLoc3 // IntLoc1"), I agree 
that integers should be used. Since the performances can be different between 
int and float, you should change the version and explain your change in the 
changelog (in the top docstring).

[issue13631] readline fails to parse some forms of .editrc under editline (libedit) emulation on Mac OS X

[Ned Deily]

Ned Deily added the comment:

It appears that Apple's update to editline in OS X 10.9 Mavericks has also 
broken this patch; with refreshing, it still works with the system editline in 
10.8. So, like the fix for Issue18458, we need to make sure that the fix works 
with either version of a dynamically loaded libedit.

Zvezdan, it would be good if you would be willing to sign the Python 
contributor agreement for your patch:

David: I had a look at the examples and documentation as you said. I found some 
support for multipart/related in the form of  `add_related` and `set_related` 
methods. But I am still confused on how to make content_manager recognize 
miltipart/related messages. Do I need to add a new content-manager instance

[issue4350] Remove dead code from Tkinter.py

[Serhiy Storchaka]

Serhiy Storchaka added the comment:

Patch is synchronized with tip. It also removes Studbutton and Tributton 
classes which depend on removed methods. These classes are not documented, not 
tested and never worked in supported Python versions. I even not found 
reasonable links in Google, except an annotation [1] and autogenerated from 
Tkinter sources docs.

I now think that perhaps we should apply this patch to 2.7 and 3.4 too. 
Non-working (and non-worked last 10 or 15 or more years) code only confuses 
people.

Serhiy, thanks for the configuration tip.  But you seem to be missing my point,

want to make it bad for experienced users, of course.  I doubt Unix users will

But I don't know why sys.modules refers the first mock object.

[issue21592] Make statistics.median run in linear time

[Thomas Dybdahl Ahle]

Thomas Dybdahl Ahle added the comment:

I don't know if it's worth the overhead to implement a multiselect, given we 
only expose a median function.

I've rewritten select2 to be intro, just falling back on sorting. This doesn't 
appear to degrade the performance.

I also added np.median to the test-suite. And it is indeed pretty snappy. 
Though not more than select2 under pypy. There is a discussion here 
https://github.com/numpy/numpy/issues/1811

== Single call mode ==
Nsort select7  select23 select47 select97 select   select2

I have no opinon on close() vs setting CLOEXEC flag, but you should use

[issue21627] Concurrently closing files and iterating over the open files directory is not well specified

[STINNER Victor]

STINNER Victor added the comment:

Since Python 3.4, all file descriptors directly created by Python are marked as 
non-inheritable. It should now be safe to use subprocess with close_fds=False, 
but the default value was not changed because third party modules (especially 
code written in C) may not respect the PEP 446.

If you are interested to change the default value, you should audit the major 
Python modules on PyPI to check if they were adapted to respect the PEP 446 
(mark all file descriptors as non-inheritable).

[issue634412] RFC 2387 in email package

[R. David Murray]

R. David Murray added the comment:

My idea (which I haven't worked out in detail) is to add either a new content 
manager that extends raw_data_manager, or just add to raw_data_manager, a 
handler for 'multipart/related'.  The set handler would handle a value of type 
'dict', and expect it to contain a mapping from content-ids to...something.  
What the 'something' is is the part I'm not clear on yet.  Trivially it could 
be MIMEParts, but that may not be the most convenient API.  Or perhaps it 
*should* be MIMEParts, with a helper utility to make building the dict easy.  
The 'get' handler would return a dict in the same format, whatever we decide 
that format should be.

[issue21594] asyncio.create_subprocess_exec raises OSError

[Sebastian Kreft]

Sebastian Kreft added the comment:

I agree that blocking is not ideal, however there are already some other 
methods that can eventually block forever, and for such cases a timeout is 
provided. A similar approach could be used here.

I think this method should retry until it can actually access the resources, 
because knowing when and how many files descriptors are going to be used is 
very implementation dependent. So handling the retry logic on the application 
side, would be probably very inefficient as lot os information is missing, as 
the subprocess mechanism is a black box.

[issue21637] Add a warning section exaplaining that tempfiles are opened in binary mode

[Sebastian Kreft]

New submission from Sebastian Kreft:

Although it is already explained that the default mode of the opened tempfiles 
is 'w+b' a warning/notice section should be included to make it clearer.

I think this is important as the default for the open function is to return 
strings and not bytes.

I just had to debug an error with traceback, as traceback.print_exc expects a 
file capable of handling unicode.

[issue21638] Seeking to EOF is too inefficient!

[Linlin Yan]

New submission from Linlin Yan:

I noticed this problem when I run a Python2 program (MACS: 
http://liulab.dfci.harvard.edu/MACS/) very inefficiently on a large storage on 
a high performace server (64-bit Linux). It was much slower (more than two 
days) than running it on a normal PC (less than two hours).

After ruling out many optimizing conditions, I finally located the problem on 
the seek() function of Python2. Now I can reproduce the problem in a very 
simple example:

#!/usr/bin/python2
f = open("Input.sort.bam", "rb")
f.seek(0, 2)
f.close()

Here, the size of file 'Input.sort.bam' is 4,110,535,920 bytes. When I run the 
program with 'strace' to see the system calls on Linux:

$ strace python2 foo.py
...
open("Input.sort.bam", O_RDONLY)= 3
fstat(3, {st_mode=S_IFREG|0644, st_size=4110535920, ...}) = 0
fstat(3, {st_mode=S_IFREG|0644, st_size=4110535920, ...}) = 0
mmap(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 
0x7f23d4492000
fstat(3, {st_mode=S_IFREG|0644, st_size=4110535920, ...}) = 0
lseek(3, 4110532608, SEEK_SET)  = 4110532608
read(3, 
"f\203\337<\334\350\313\315\345&T\227\211\fC\212a\260\204P\235\366\326\353\230\327>\373\361\221\357\373"...,
 3312) = 3312
close(3)= 0
...

It seems that python2 just move file cursor to a specific position (4110532608 
in this case) and read ahead the rest bytes, rather than seek to the file end 
directly. I tried to run the exact the same program on the large storage, the 
position changed to 1073741824, left 889310448 bytes to read to reach the file 
end, which reduced the performance a lot!

[issue21639] tracemalloc crashes with floating point exception when using StringIO

[Claudiu.Popa]

New submission from Claudiu.Popa:

Given the following code, tracemalloc crashes with:
"Floating point exception: 8 (core dumped)"

import tracemalloc
tracemalloc.start(10)
import io
io.StringIO()

The culprit is this line "assert(nelem <= PY_SIZE_MAX / elsize);" from 
tracemalloc_alloc. elsize is 0 from stringio.c, "self->buf = (Py_UCS4 
*)PyMem_Malloc(0);".
The attached patch skips the assert if elsize is 0, but I don't know if this is 
the right approach.
Thanks!

[issue21559] OverflowError should not happen for integer operations

[R. David Murray]

R. David Murray added the comment:

Your second bullet item would seem to me to be the obvious interpretation of 
the docs.  This is, after all, Python, so 'integer' would refer to Python 
integers and their operations.  So I agree with Stefan that the docs are 
correct as they stand.  As he also said, there may be places where 
OverflowError is currently raised that may not be appropriate, especially since 
we are dealing with a codebase that once had Python integer operations that 
*could* overflow.

[issue21641] smtplib leaves open sockets around if SMTPResponseException is raised in __init__

[Claudiu.Popa]

New submission from Claudiu.Popa:

Hello!

I noticed that test_smtplib raises a ResourceWarning, tracking this to this 
piece of code:

   self.assertRaises(smtplib.SMTPResponseException, smtplib.SMTP,
 HOST, self.port, 'localhost', 3)

What happens is that `SMTP.getreply` is called in `SMTP.__init__` after the 
socket was opened, but if getreply raises SMTPResponseException, the socket 
remains opened. The attached patch fixes this.

[issue14150] AIX, crash loading shared module into another process than python like operator.so results in 0509-130

[Michael Haubenwallner]

Michael Haubenwallner added the comment:

Doing it this way strictly requires runtime-linking to be enabled, to have "the 
main executable" and the module use the same runtime instance of the 
libpython${VERSION}.so symbols.

Instead, "the main executable" better should re-export the python symbols 
itself. This requires httpd to be linked with "-bE:/path/to/python.exp" linker 
flag.

[issue21561] help() on enum34 enumeration class creates only a dummy documentation

[Ethan Furman]

Ethan Furman added the comment:

I think something like the following, taken from 
http://bugs.python.org/issue19030#msg199920, shoud do the trick for something 
to test against:

class Meta(type):
def __getattr__(self, name):
if name == 'ham':
return 'spam'
return super().__getattr__(name)

class VA(metaclass=Meta):
@types.DynamicClassAttribute
def ham(self):
return 'eggs'

which should result in:

VA_instance = VA()
VA_instance.ham  # should be 'eggs'
VA.ham   # should be 'spam'

Combining all that with the DynamicClassAttribute should make a fitting test.  
Thanks, Andreas, for working on that.

[issue6167] Tkinter.Scrollbar: the activate method needs to return a value, and set should take only two args

[Jim Jewett]

Jim Jewett added the comment:

I'm still not seeing why these changes are sufficiently desirable to justify 
the code churn.  Nor am I seeing test or doc changes that would explain the 
advantages of the new way, and prevent future regressions.

I agree that the changes would make the signatures better for the typical use 
cases for this particular widget -- but wouldn't they also break the common 
interface for the "set" and "activate" methods across several types of tkinter 
widget?  

If so, then instead of changing or restricting the method, it would be better 
to add examples (and maybe even an explanation) to the documentation (including 
the docstring).




In particular:

(1)  Why change actrivate's parameter from "index" to "element"?  I agree that 
"element" is a better name for the normal case, but 
https://docs.python.org/dev/library/tkinter.html#the-index-parameter
strongly suggests that "index" is more consistent with the rest of tkinter, and 
that there are use cases wehre "index" is the right name.  If that is not true, 
please say so explicitly, at least in comments.

(2)  Why change the "set" method?  I understand that a more specific signature 
is desirable, and I assume that other values would be ignored (or raise an 
exception), but the set method seems to have an existing API across several 
widgets -- and that shouldn't be broken lightly.

[issue10652] test___all_ + test_tcl fails (Windows installed binary)

[Zachary Ware]

Zachary Ware added the comment:

As for what's actually wrong here, Hirokazu Yamamoto's diagnosis in msg123615 
(adjusted for 2.7) is correct.

Either of the last two patches I posted should work to fix this issue, but 
they're both just band-aids rather than a real, once-and-for-all fix.  #20035 
(which I need to rewrite again) will be a once-and-for-all fix for 3.5 by 
getting rid of tkinter._fix, but I'm not sure if such an invasive fix is 
appropriate for 2.7 and 3.4.  I prefer the second band-aid (import FixTk at the 
top of test_support) just because it's simpler and also prevents the 
'os.environ has been changed' warnings.

A workaround that doesn't require a patch is to just set TCL_LIBRARY manually 
in your environment before running the tests, which is how the 3.x buildbots 
are currently working (see Tools/buildbot/test.bat:4).

For the record, I'm not sure why the 3.x fix we came up with earlier in this 
issue worked, though I suspect it has something to do with _fix being part of 
the tkinter package.  The same patch fails on 2.7 because Tkinter is not a 
package; FixTk is a standalone module and is thus completely unaffected by 
support.import_fresh_module('Tkinter').  Fresh-importing FixTk itself works, 
since it's what we actually need to run.

[issue21594] asyncio.create_subprocess_exec raises OSError

[Guido van Rossum]

Guido van Rossum added the comment:

I'm not sure. Running out of file descriptors is really not something a
library can handle on its own -- this needs to be kicked back to the app to
handle. E.g. by pacing itself, or closing some connections, or changing the
system limit... The library really can't know what to do, and just waiting
until the condition magically clears seems asking for mysterious hangs.

[issue21623] build ssl failed use vs2010 express

[Zachary Ware]

Zachary Ware added the comment:

The first error makes no sense to me.  What version of OpenSSL are you 
building?  How did you invoke the Python build (command line, or through the VS 
GUI)?

As for the second error, all of the VS-generated files in PCbuild have a UTF-8 
BOM, which is what the 'gbk' codec can't handle.

[issue15988] Inconsistency in overflow error messages of integer argument

[Terry J. Reedy]

Terry J. Reedy added the comment:

I reconsidered this in the light of #21559. getargs_b requires an integer of 
type int in range(256). A non-int properly raises TypeError.

>>> from _testcapi import getargs_b as gb
>>> gb(1.0)
Traceback (most recent call last):
  File "", line 1, in 
gb(1.0)
TypeError: integer argument expected, got float
>>> import fractions
>>> gb(fractions.Fraction(1, 1))
Traceback (most recent call last):
  File "", line 1, in 
gb(fractions.Fraction(1, 1))
TypeError: an integer is required (got type Fraction)

An out-of-range int should, it seems to me, just raise ValueError("int %d not 
in range(256)" % n). Verification of the range:

>>> gb(255)
255
>>> gb(256)
Traceback (most recent call last):
  File "", line 1, in 
gb(256)
OverflowError: unsigned byte integer is greater than maximum
>>> gb(0)
0
>>> gb(-1)
Traceback (most recent call last):
  File "", line 1, in 
gb(-1)
OverflowError: unsigned byte integer is less than minimum

The last message is wrong or contradictory. An unsigned (non-negative) int 
cannot be less than 0.

[issue21573] Clean up turtle.py code formatting

[R. David Murray]

R. David Murray added the comment:

A side note about tests: once a couple or three years ago I made it so that you 
could run 'make doctest' against the turtle documentation and it would work 
(displaying stuff on the screen).  There's no checking of the output, but it 
proved the examples at least executed cleanly (with the help of some 
sphinx-hidden extra code).

For whatever it is worth, they still appear to run to completion:

Document: library/turtle

1 items passed all tests:
 313 tests in default
313 tests in 1 items.
313 passed and 0 failed.
Test passed.

[issue21559] OverflowError should not happen for integer operations

[Terry J. Reedy]

Terry J. Reedy added the comment:

I was tempted to close this, but I think there is an issue that 'theme' has 
implied but not stated clearly enough. The OverflowError entry might be 
re-written as "Raised when the result of an arithmetic operation involving at 
least one non-int is too large to be represented. For pairs of ints, 
MemoryError is raised instead." This much is true. However, the clear 
implication is that a binary operation on non-ints is the only situation in 
which OverflowError is raised. But as theme has shown, it is not. In this 
sense, the doc is incomplete.

Another, unstated, situation is failure of an internal conversion from an int 
to an internal type. In #20539, #20539, the justification for switching from 
MemoryError to OverflowError when factorial input grows too large for 
conversion is that memory is then not filled. In #21444, the justification is 
history.

A third possibility is that OverflowError is used instead of ValueError when an 
int fails a simple range check. See #15988: _testcapi.getargs_b requires an int 
in range(256). -1 and 256 raise OverflowErrors. #7267 is about the same issue. 
An int not being in range(256) has nothing to do with the merging of integer 
types in 3.x.

So I think that the docs need a new sentence. Both alternatives can be 
summarized by "OverflowError may also be raised for integers that are outside a 
required range." Knowing this might help people debugging such situations.

[issue21642] "_ if 1else _" does not compile

[Joshua Landau]

New submission from Joshua Landau:

By the docs,

Except at the beginning of a logical line or in
string literals, the whitespace characters space,
tab and formfeed can be used interchangeably to
separate tokens. Whitespace is needed between two
tokens only if their concatenation could otherwise
be interpreted as a different token
(e.g., ab is one token, but a b is two tokens).

"_ if 1else _" should compile equivalently to "_ if 1 else _".

The tokenize module does this correctly:

import io
import tokenize

def print_tokens(string):
tokens = tokenize.tokenize(io.BytesIO(string.encode("utf8")).readline)  
  

for token in tokens:
print("{:12}{}".format(tokenize.tok_name[token.type], token.string))

print_tokens("_ if 1else _")
#>>> ENCODINGutf-8
#>>> NAME_
#>>> NAMEif
#>>> NUMBER  1
#>>> NAMEelse
#>>> NAME_
#>>> ENDMARKER   

but it fails when compiled with, say, "compile", "eval" or "ast.parse".

import ast

compile("_ if 1else _", "", "eval")
#>>> Traceback (most recent call last):
#>>>   File "", line 32, in 
#>>>   File "", line 1
#>>> _ if 1else _
#>>>   ^
#>>> SyntaxError: invalid token

eval("_ if 1else _")
#>>> Traceback (most recent call last):
#>>>   File "", line 40, in 
#>>>   File "", line 1
#>>> _ if 1else _
#>>>   ^
#>>> SyntaxError: invalid token

ast.parse("_ if 1else _")
#>>> Traceback (most recent call last):
#>>>   File "", line 48, in 
#>>>   File "/usr/lib/python3.4/ast.py", line 35, in parse
#>>> return compile(source, filename, mode, PyCF_ONLY_AST)
#>>>   File "", line 1
#>>> _ if 1else _
#>>>   ^
#>>> SyntaxError: invalid token

Further, some other forms work:

1 if 0b1else 0
#>>> 1

1 if 1jelse 0
#>>> 1

[issue21559] OverflowError should not happen for integer operations

[R. David Murray]

R. David Murray added the comment:

"Integers are outside a required range" makes me wonder why it isn't a 
ValueError.  An OverflowError should be the result of a *computation*, IMO, not 
a bounds check.

So, maybe add your sentence with the additional phrase "for historical 
reasons"? :)

[issue1191964] asynchronous Subprocess

[Josiah Carlson]

Josiah Carlson added the comment:

First, with the use of Overlapped IO on Windows, BlockingIOError should never 
come up, and we don't even handle that exception.

As for BrokenPipeError vs. EOF; while we do treat them more or less the same, 
we aren't killing the process or reporting that the process is dead, and we 
tell users to check the results of Popen.poll() in the docs.

Could we bubble up BrokenPipeError? Sure. Does it make sense? In the case of 
Popen.communicate(), exposing the error and changing expected behavior doesn't 
make sense.

I have implemented and would continue to lean towards continuing to hide 
BrokenPipeError on the additional API endpoints. Why? If you know that a 
non-blocking send or receive could result in BrokenPipeError, now you need to 
wrap all of your communication pieces in BrokenPipeError handlers. Does it give 
you more control? Yes. But the majority of consumers of this API (and most APIs 
in general) will experience failure and could lose critical information before 
they realize, "Oh wait, I need to wrap all of these communication pieces in 
exception handlers."

I would be open to adding either a keyword-only argument to the methods and/or 
an instance attribute to enable/disable raising of BrokenPipeErrors during the 
non-blocking calls if others think that this added level of control. I would 
lean towards an instance attribute that is defaulted to False.

[issue21643] "File exists" error during venv --upgrade

[Virgil Dupras]

New submission from Virgil Dupras:

There seems to have been a regression in Python 3.4.1 with "pyvenv --upgrade", 
and this regression seems to be caused by #21197.

It now seems impossible to use the "--upgrade" flag without getting a "File 
exists" error. Steps to reproduce:

$ pyvenv env
$ pyvenv --upgrade env
Error: [Errno 17] File exists: '//env/lib' -> '//env/lib64'

[issue18373] implement sys.get/setbyteswarningflag()

[Daniel Holth]

Daniel Holth added the comment:

As an aside, why wouldn't I run my program with -bb?

One reason is that the following code won't work on Linux:

#!/usr/bin/env python -bb

Instead of passing -bb to Python, it will look for an executable called "python 
-bb", and it's not likely to find it.

The original reason was that I did not know about -bb.

[issue6167] Tkinter.Scrollbar: the activate method needs to return a value, and set should take only two args

[Terry J. Reedy]

Terry J. Reedy added the comment:

1. In activate, change parameter 'index' to 'element'.  I agree with Jim about 
rejecting this. A (specific). 'index' is routinely used to point to an item in 
a sequence; "arrow1", "slider", and "arrow2" are visually sequenced. The doc 
string is clear on the possible indexes Text also uses words for indexes. B 
(general). we don't break code by renaming arguments; I am pretty sure that any 
exception one might raise does not apply to this issue.

2. Give index a default of None and return the result of calling tk with None, 
instead of tossing it. I believe this enhancement would make activate more 
consistent with other methods. If so, do it -- with an added test.

3. Give .set() specific parameters. I think the current docstring is a bit 
confusing and should be revised. Am I correct in thinking that on a vertical 
slider, the upper end get the lower value, whereas the lower end gets the 
higher value? And that one should call bar.set(.3, .6) rather than bar.set(.6, 
.3)? If so, calling the parameters 'lowval' and 'hival' might be clearer.

Does msg201484 mean that tk requires exactly 2 args? If so, some change seems 
ok. Deleting 'args' cannot in itself break code as 'args' cannot be used as a 
keyword. I agree with not adding defaults,
