[issue6259] ctypes pointer arithmetic

[Chris Angelico]

Chris Angelico added the comment:

Nudging this as a forgotten patch. Is anyone at all interested in this, or 
should it be closed as not worth the hassle? The patch is ancient and doesn't 
apply to 3.6.

Propose closing, to clean up the tracker. It can always be reopened if the 
patch is updated to current.

[issue25375] Don't mention 2.2 in the 3.x docs

[Chris Angelico]

New submission from Chris Angelico:

See: https://mail.python.org/pipermail/python-list/2015-October/697818.html

Saying "In Python 2.2" is not helpful in the 3.x docs. Even in the 2.x docs, 
it's pretty safe to assume by now that everyone's on 2.2+. (At very least, 
"Since" would be better than "If".) Patch attached.

I suspect that a lot of that FAQ is outdated now, though.

[issue24575] timemodule build fail - missing definitions for _Py_BEGIN_SUPPRESS_IPH and _Py_END_SUPPRESS_IPH

[Ilya Kulakov]

Ilya Kulakov added the comment:

Why is it important to hide these 2 macroses behind Py_BUILD_CORE?

Certain tools for embedding python may try to compile modules independently. I 
realize that it's not a problem of Python to take care of that, but in that 
particular case if hiding these 2 macroses behind Py_BUILD_CORE is not 
required, it may help to retain compatibility with such tools.

[issue25303] Add option to py_compile to compile for syntax checking without writing bytecode

[Pavel Roskin]

Pavel Roskin added the comment:

Thank you for the comments. I was annoyed by py_compile making files with names 
very similar to the original scripts, names that could not even be recognized 
by shell patterns in .gitignore unless scripts ending with "c" are banned. But 
that problem is addressed in Python 3. I don't really care what files are in 
__pycache__, I won't have that urge to remove them. And then I simply was 
annoyed by the fact that py_compile was ignoring my attempts to suppress its 
output. Now I understand the reason for that. Migrating to Python 3 would 
address my original problem with strange looking cache files. I'm going to 
close this issue.

[issue25374] Deficiencies in type hint usage in Python standard libraries

[John Michael Lafayette]

New submission from John Michael Lafayette:

I love the new type hint feature in Jetbrains IDE (PEP 0484). Now when my user 
defined methods return a value, I can press (Crtl+space) and see the type of 
that value and all its methods. Also, when I pass the wrong type in, I get a 
warning. 

Oddly, this does not happen with Python standard library functions. I can't get 
the auto-complete on objects returned by the Python standard library. The 
Python standard library doesn't warn me in advance if I put the wrong type in a 
method. How does that make sense? Please support PEP 0484 by using it in the 
Python standard library where appropriate.

[issue25373] test.regrtest: -jN (with N != 1) + --slow + child error or interruption = TypeError

[Arfrever Frehtes Taifersar Arahesis]

New submission from Arfrever Frehtes Taifersar Arahesis:

Function runtest() (used by single-process mode) always returns tuple with test 
result as integer and test time as float.
This tuple is passed as second argument to function accumulate_result(), which 
has (in Python 3.6):
def accumulate_result(self, test, result):
ok, test_time = result
self.test_times.append((test_time, test))

test_times is later used by code, which expects that times are floats:
if self.ns.print_slow:
self.test_times.sort(reverse=True)
print("10 slowest tests:")
for time, test in self.test_times[:10]:
print("%s: %.1fs" % (test, time))

Code used by multi-process mode can return tuple with integer and string 
(describing error in subprocess), which with --slow option would cause 
TypeError.


Example:

In terminal 1:
$ LD_LIBRARY_PATH="$(pwd)" ./python -m test.regrtest -j2 --slow test_lib2to3

In terminal 2 (sufficiently quickly):
$ kill -SIGINT $(ps aux | grep '"test_lib2to3"' | grep -v grep | awk '{print 
$2}')

Output in terminal 1:

Test suite interrupted by signal SIGINT.
1 test omitted:
test_lib2to3
10 slowest tests:
Traceback (most recent call last):
  File "/tmp/cpython/Lib/runpy.py", line 170, in _run_module_as_main
"__main__", mod_spec)
  File "/tmp/cpython/Lib/runpy.py", line 85, in _run_code
exec(code, run_globals)
  File "/tmp/cpython/Lib/test/regrtest.py", line 39, in 
main_in_temp_cwd()
  File "/tmp/cpython/Lib/test/libregrtest/main.py", line 451, in 
main_in_temp_cwd

  File "/tmp/cpython/Lib/test/libregrtest/main.py", line 429, in main
Regrtest().main(tests=tests, **kwargs)
  File "/tmp/cpython/Lib/test/libregrtest/main.py", line 389, in main
self.display_result()
  File "/tmp/cpython/Lib/test/libregrtest/main.py", line 261, in display_result
print("%s: %.1fs" % (test, time))
TypeError: a float is required


My suggested fix is to return string describing error as third element of that 
tuple.

[issue25372] load_module() does not link submodule to parent package

[R. David Murray]

R. David Murray added the comment:

I'm no expert on pep 302 either, but I'm guessing this is an intentional part 
of the design.  You'll note that updating the namespace is *not* mentioned as 
one of the things load_module has to do.  The update of the namespace is 
something the import system as a whole implements, and I'm not sure where it 
happens (probably __import__/import_module).

Unless you are saying that this is a regression, it doesn't really matter if it 
was intentional or not, since if it is not a regression then it's been that way 
for a long time.

[issue25372] load_module() does not link submodule to parent package

[Martin Panter]

New submission from Martin Panter:

The load_module() API adds an entry to sys.modules when loading a submodule, 
but does not add the submodule as an attribute in the parent package. I am no 
expert on PEP 302 or the import system, but this feels like a bug to me:

>>> import sys, pkgutil
>>> loader = pkgutil.find_loader("xml.etree")
>>> loader.load_module("xml.etree")

>>> sys.modules["xml.etree"]  # Entry added, per documentation and PEP 302

>>> hasattr(sys.modules["xml"], "etree")  # But not linked to parent!
False
>>> import xml.etree
>>> xml.etree  # Broken :(
Traceback (most recent call last):
  File "", line 1, in 
AttributeError: 'module' object has no attribute 'etree'

Building Python 3.5 requires Visual Studio 2015 and Windows 8.1, so this would 
be a vanishingly small audience that's building to deploy on old 32-bit Windows 
7 machines. I don't think the PSF needs to worry about this. Anyway, the "/arch 
(x86)" docs [1] explain how to configure a project to use IA32, and 
PCBuild/readme.txt [2] explains how to build Python using Visual Studio 2015. I 
know this doesn't really help a novice user; just tell them to install Python 
3.4!

[issue25370] Add support of pickling very large bytes and str objects with protocol < 4

[Serhiy Storchaka]

New submission from Serhiy Storchaka:

Pickle protocols < 4 allow to pickle bytes and str object with 32-bit size. One 
of features of protocol 4 was the support of 64-bit sizes.

It is possible to add support of very large bytes and str objects with 
protocols 2 and 3. The idea is that the long string is splitted on chunks with 
32-bit sizes and the resulting string is reconstructed with calling ''.join(). 
The main part of the feature can be implemented in Python as helpers in copyreg.

The question is: is it worthwhile to implement this feature? I already 
implemented two other features of protocol 4 for protocols 2 and 3: nested 
objects and __new__ with keyword arguments.

Windows 8 is the first to require SSE2 [1][2]. I'm sure it's no coincidence 
that this became the default in VS 2012. 

There is probably a small minority of users that upgraded to 32-bit Windows 7 
on old hardware. Python 3.5 excludes them, but I don't think the build should 
switch to using /arch:IA32 just to support them. If a user on such a system 
really needs 3.5, it's possible to create a private build without SSE2. Most 
packages that have extension modules will also have to be built from source 
instead of using prebuilt wheels.

[issue24870] Optimize ascii and latin1 decoder with surrogateescape and surrogatepass error handlers

[INADA Naoki]

INADA Naoki added the comment:

UTF-8 and Latin1 are typical encoding for MySQL query.
When inserting BLOB:

# Decode binary data
x = data.decode('ascii', 'surrogateescape')
# %-format query
psql = sql % (escape(x),)  # sql is unicode
# Encode sql to connection encoding (latin1 or utf8)
query_bytes = psql.encode('utf-8', 'surrogateescape')

So decoder speedup is required only for ascii, but encoder speedup is required 
for utf-8 and latin1.

I'll consider other ways including creating speedup module and register it on 
PyPI.

[issue25194] Opt-in motivations & affiliations page for core contributors

[Ezio Melotti]

Ezio Melotti added the comment:

A few comments:

1) In the "Restrictions on scope" section, you could turn "Contributor 
Licensing Agreement" into a link.
2) You call this a "program" in a couple of place, and I'm not sure that's the 
right term (to me "program" sounds like an organized effort brought forward by 
the PSF rather than just a self-compiled list of names).
3) I would have kept the 2 disclosure-related cases separate from the 
availability for paid work, but I guess practicality beats purity and the 
paragraph you added to clarifies the difference does a good-enough job.
4) In the "commercial contacts" bullet point, you could clarify what kind of 
contacts are allowed (e.g. link, email address, phone numbers, company address, 
etc.).
5) Several devs already have a bio page on the wiki.  Instead of repeating it 
here, it might be easier to just add a link to that.  This makes the list 
shorter and easier to read, and allows people to write as much as they want on 
their wiki page.
6) If the bio is moved to the wiki, a more concise table-based approach might 
work better.  The table can include columns for names, affiliations, 
availability for paid work (just a check mark), link to bio, and possibly other 
links.

[issue25363] x=[1,2,3].append([1,2,3]) bug

[Xiang Zhang]

Xiang Zhang added the comment:

This is the right behaviour.

x=[1, 2, 3].append([1, 2, 3]) acts as:

x=([1, 2, 3].append([1, 2, 3])

Since append is a in-place operation it return None. Then x is None.

[issue25356] Idle (Python 3.4 on Ubuntu) does not allow typing accents

[Gian Carlo Martinelli]

Gian Carlo Martinelli added the comment:

@Terry
Using 'Find in Files' (Alt+F3) works fine. I can type everything normally. Also 
in the Output everything is fine.

Apparently the problem is only with diacriticals (I mentioned 'ç', but it is 
working (I have a particular key for that in my keyboard... it is a Brazilian 
keyboard)).

@Serhiy
The problem is both with standalone keys ('`~^) and accented characters (ãẽéáà 
etc)



Today I found a very strange behaviour.

IF I start IDLE with a clean file, everything works fine. 

If then I open a .py file, or save the new file as .py, after 3-5 seconds these 
keys stop working. Very strange...

I hope I was clear in describing this.

@Ankit: check if this behavior is the same for you.

[issue25361] Is python-3-5-0.exe compiled with SSE2 instrutions? If so should we mention this?

[eryksun]

eryksun added the comment:

With Visual Studio 2010 and earlier, SSE support had to be explicitly enabled. 
Starting with VS2012 it's on by default [1]:

Because the x86 compiler generates code that uses SSE2 
instructions by default, you must specify /arch:IA32 to 
disable generation of SSE and SSE2 instructions for x86 
processors.

For 3.5, the 32-bit build does use SSE2 instructions. For example, float_add 
uses the addsd instruction (opcode F2 0F 58):

0:000> s python35!float_add l100 f2 0f 58
71f6c5d8  f2 0f 58 44 24 08 8b 0d-84 11 18 72 f2 0f 11 44  ..XD$..r...D
0:000> u 71f6c5d8 l3
python35!float_add+0x98:
71f6c5d8 f20f58442408addsd   xmm0,mmword ptr [esp+8]
71f6c5de 8b0d84111872mov ecx,dword ptr [python35!free_list 
(72181184)]
71f6c5e4 f20f11442410movsd   mmword ptr [esp+10h],xmm0

Thus 3.5 doesn't support older CPUs that lack SSE2, such as the AMD Athlon XP. 
I didn't check the installer itself, but that would be a pointless exercise.

[issue5380] pty.read raises IOError when slave pty device is closed

[Xavier de Gaye]

Xavier de Gaye added the comment:

The line discipline [1] of a terminal driver and a pty is controlled by 
terminal attributes set with tcsetattr() [2][3].

IMHO (as a developer running ptys over asyncio), using a pty implies writing 
code at the low level such as configuring the line discipline, or possibly 
dealing with the notions of controlling terminal, process group and so on. So 
it seems right that Python io would not support ptys as Python io sits at a 
higher level.

[issue25341] File mode wb+ appears as rb+

[Mark Williams]

Mark Williams added the comment:

Python's test suite may test the current behavior but that does not lessen
the problem.

I gave an example of apparently correct code that fails (that was actually
encountered by a Python user) in my original description.  Another such
example: you cannot duplicate a file object -- same path, same mode --- and
be sure that the duplicate is a true duplicate.  Data corruption could
occur in application code if the duplicated file were opened "rb+" instead
of "wb+", as the duplicate would not truncate existing data.

Another way to think about the problem is accuracy of intent.  The mode
attribute on file objects can be incorrect, and by "incorrect" I mean "not
describe the mode under which the file was opened."  Why have a mode
attribute at all, then?  I, for one, would prefer *no* mode attribute to
one that's sometimes incorrect.  But a correct one is even better!
