[issue27099] IDLE: turn built-in extensions into regular modules

[Terry J. Reedy]

Terry J. Reedy added the comment:

The warning is from code context.  The callback after loops run whether one 
uses context or not and there is currently no mechanism to stop them.  I will 
add a cancel function soon.  Or the loops might be eliminated by adding context 
to the config change notification mechanism.

[issue27144] concurrent.futures.as_completed() memory inefficiency

[STINNER Victor]

STINNER Victor added the comment:

"concurrent.futures.as_completed() memory inefficiency" hum, sadly the commit 
97e1b1c81458d2109b2ffed32ffa1eb643a6c3b9 introduced a reference leak. Example:

$ ./python -m test -R 3:3 -test_concurrent_futures -m 
test.test_concurrent_futures.ProcessPoolAsCompletedTests.test_zero_timeout
(...)
test_concurrent_futures leaked [27, 27, 27] references, sum=81
test_concurrent_futures leaked [16, 17, 16] memory blocks, sum=49
(...)

[issue12154] PyDoc Partial Functions

[Aaron Hall]

Aaron Hall added the comment:

It seems that this issue is still properly open. (Another open issue seems be 
related: http://bugs.python.org/issue30129)

In the docs on partial, we have:

>>> from functools import partial
>>> basetwo = partial(int, base=2)
>>> basetwo.__doc__ = 'convert base 2 string to int'

But the help function doesn't find that __doc__:

>>> help(basetwo)
class partial(builtins.object)
 |  partial(func, *args, **keywords) - new function with partial application
...

Perhaps this could be solved by having PyDoc check for isinstance of a Callable 
or making partial an instance of a Function?

>>> type(basetwo)

>>> basetwo.__dict__
{'__doc__': 'convert base 2 string to int'}
>>> type(basetwo)

>>> isinstance(basetwo, partial)
True
>>> from types import FunctionType; from collections import Callable
>>> isinstance(basetwo, FunctionType)
False
>>> isinstance(basetwo, Callable)
True

The partial repr seems to get us close:

>>> repr(basetwo)
"functools.partial(, base=2)"

I haven't dug much further into this, but I'm interested in doing the work to 
finish it, and I don't think the patch submitted 6 years ago quite gets us 
there. Any other thoughts before I decide to give it a go?

[issue31332] Building modules by Clang with Microsoft CodeGen

[Tatsunori Uchino]

New submission from Tatsunori Uchino:

Microsoft released a new compiler for VC++ that complies with more of modern 
C++ than the standard compiler.

https://blogs.msdn.microsoft.com/vcblog/2016/03/31/clang-with-microsoft-codegen-march-2016-released/

Is it possible to support it by creating a new script based on  
Lib/distutils/msvccompiler.py to Lib/distutils and adding a new item in the 
following dictionary in Lib/distutils/ccompiler.py?  


compiler_class = { 'unix':('unixccompiler', 'UnixCCompiler',
   "standard UNIX-style compiler"),
   'msvc':('_msvccompiler', 'MSVCCompiler',
   "Microsoft Visual C++"),
   'cygwin':  ('cygwinccompiler', 'CygwinCCompiler',
   "Cygwin port of GNU C Compiler for Win32"),
   'mingw32': ('cygwinccompiler', 'Mingw32CCompiler',
   "Mingw32 port of GNU C Compiler for Win32"),
   'bcpp':('bcppcompiler', 'BCPPCompiler',
   "Borland C++ Compiler"),
 }

The executable of it is at C:\Program Files (x86)\Microsoft Visual Studio 
14.0\VC\ClangC2\bin\amd64.  The help message of it is:

[issue31331] IDLE: Move prompts with input.

[Terry J. Reedy]

New submission from Terry J. Reedy:

When this program (from thread by Steven D'Aprano) on python-list is run

import time
from threading import Timer

def do_work():
x = 2 + 2
print("It is", time.asctime(), "and 2+2 is", x)

def go():
Timer(10, do_work, ()).start()  # schedule it in one minute

The response, if it occurs while one in entering a statement, 'pushes down' the 
entry in progress.

=== RESTART: F:\Python\mypy\tem.py ===
>>> go()
>>> It is Sat Sep  2 19:42:10 2017 and 2+2 is 4  #<== output
a = (
12,   # <== 2nd line of entry in progress

The prompt should be pushed down too.

[issue14976] queue.Queue() is not reentrant, so signals and GC can cause deadlocks

[Raymond Hettinger]

Raymond Hettinger added the comment:

[Guido]
> Why was task management ever added?

See http://bugs.python.org/issue1455676

Problem being solved:  How can a requestor of a service get notified when that 
service is complete given that the work is being done by a daemon thread that 
never returns.

[issue14976] queue.Queue() is not reentrant, so signals and GC can cause deadlocks

[Tim Peters]

Tim Peters added the comment:

[Guido]
> Why was task management ever added?

Raymond published a "joinable" queue class as a recipe here:

http://code.activestate.com/recipes/475160-taskqueue/

and later folded it into the standard Python queue.  So the usual answer 
applies:  "it was easy to add and sometimes useful, so it seemed like a good 
idea at the time" ;-)

Also document in idle doc that 'import idlelib.idle' is the programmatic API, 
and that icons and context menus may be available.  In any case, add more 
information on 'How to start IDLE'.

[issue14976] queue.Queue() is not reentrant, so signals and GC can cause deadlocks

[Antoine Pitrou]

Antoine Pitrou added the comment:

Just a random thought: if there was a SimpleQueue class with very basic 
functionality (only FIFO, only get(), put() and empty(), no size limit, no task 
management), it would be easier to make it reentrant using C.

(FTR, multiprocessing also has a light-weight SimpleQueue)

Dan, not sure you're still interested on working on this?
Looking at the API, IMHO it should be consolidated as a simple stats() method, 
which allows for a consistent snapshot.

[issue31330] argparse.RawTextHelpFormatter does not maintain lines separated by more than one newline

[paul j3]

paul j3 added the comment:

http://bugs.python.org/issue17113
argparse.RawDescriptionHelpFormatter should not delete blank lines

This provides more details on why this is happening.

I suggest using adding a space between newlines, thus: '\n \n'.  
HelpFormatter.format_help is just looking for '\n\n'.

[issue31330] argparse.RawTextHelpFormatter does not maintain lines separated by more than one newline

[paul j3]

paul j3 added the comment:

I've seen this before, either in another bug/issue or a Stackoverflow question.

The basic change in RawTextHelpFormatter is to turn off the line wrapping for 
texts like the description.  Multiple newlines are preserved at this step.

But after assembling all the pieces (usage, description, help, epilog) the 
formatter strips out duplicate newlines.  This is needed because the process of 
assembly freely inserts newlines between the pieces, regardless of whether they 
are blank or not.  It can't, or at least doesn't try to, distinguish between 
newlines within a block like the description, and newlines between blocks.

If someone could come up with a simple patch, great.  Or a simple change to the 
doc wording.  But I don't think this issue merits a larger fix.

[issue31330] argparse.RawTextHelpFormatter does not maintain lines separated by more than one newline

[R. David Murray]

R. David Murray added the comment:

If that is the intended definition of "whitespace" in this context (I have no 
opinion on that so far), then the docs need amplification, because in general 
"whitespace" includes newlines.  On the other hand, this might be considered a 
bug in the code and not the docs.  However, changing it has backward 
compatibility implications, so we might go for a doc fix regardless.
