[issue25223] Statically or dynamically linked to the VC++runtime ? or how Python install fails on Vista despite the VC redist packages - api-ms-win-crt-runtime-l1-1-0.dll

[acx01bc]

acx01bc added the comment:

@steve.dower : the vc_redist packages doesn't list the files it installs, I'm 
not sure of the names of the files, but who cares, please look at my screenshot 
of dependency walker, it shows how different versions of Python win32 releases 
that I downloaded on python.org (3.5.0, 3.4.3,3.3.x) used different vc-runtime 
settings, and how some of them don't work on Vista.

@Wolfgang Langner : "this update doesn't apply to you system" :-)

So what I'm saying is : please be careful with the compiler options if you want 
you executables to be compatible with vista/7/8/10

[issue25232] CGIRequestHandler behave incorrectly with query component consisting mutliple ?

[Xiang Zhang]

New submission from Xiang Zhang:

According to rfc3986, section 3.4:

 The query component is indicated by the first question
 mark ("?") character and terminated by a number sign ("#") character
 or by the end of the URI.

 The characters slash ("/") and question mark ("?") may represent data
 within the query component.

But for CGIRequestHandler, it uses the content after the last ? as
query component. For uri http://localhost:8000/cgi-bin/test.py?a=b?c=d,
the QUERY_STRING is c=d.

[issue25223] Statically or dynamically linked to the VC++runtime ? or how Python install fails on Vista despite the VC redist packages - api-ms-win-crt-runtime-l1-1-0.dll

[Steve Dower]

Steve Dower added the comment:

In your original post you refer to the "famous 
api-ms-win-crt-runtime-l1-1-0.dll problem" - I am not aware of this problem, so 
you will need to provide more context on what is actually not working for you.

Dependency Walker doesn't know how to resolve those DLLs on any platform - 
Win10 looks exactly the same. A limitation of a diagnostic tool that hasn't 
been updated in years does not qualify as something "not working".

But since you've closed the issue I have to assume that it isn't really an 
issue.

[issue18967] Find a less conflict prone approach to Misc/NEWS

[R. David Murray]

R. David Murray added the comment:

Because the two summaries should be *different* in most cases.  The first line 
of the checkin should ideally be a single sentence of less than 80 characters, 
while the NEWS item will almost always be longer.  The NEWS item should be a 
complete summary, while the first checkin line is a 'summary in context' (ie: 
it can assume the reader knows the files that were changed, since log -v will 
show you that).  This obviously requires that the succeeding paragraphs expand 
on that minimal summary (in most cases) in a way that doesn't look like a NEWS 
entry.

Now, this is obviously my preferred style and others may have different styles 
and/or disagree, but I'd like that style to be supported.

Note also that a big part of putting the NEWS entries in the tracker is so that 
they can be *edited*.  Populating them initially from the checkin message is 
OK, but I predict that the actual workflow will be to create the NEWS entry in 
the tracker as part of getting the patch to the 'commit ready' point, which 
means that having a tool that pre-populates the commit message from the tracker 
NEWS entry will probably be more useful to most people.  (And yeah, I'm sure 
that means a lot of commits will just have the NEWS entry as the commit 
message, which will make me sad, but oh well :)

[issue24657] CGIHTTPServer module discard continuous '/' letters from params given by GET method.

[Xiang Zhang]

Xiang Zhang added the comment:

The path with query component are unquoted entirely and then pass into
_url_collapse_path.
I think this behaviour is wrong and according to rfc3875 query component
should be left encoded in QUERY_STRING.
This patch seems to solve the problem. It passes the tests and with
martin's script, it gets:

('QUERY_STRING', 'k=aa%2F%2Fbb&//q//p//=//a//b//')

has the same behaviour with apache.

[issue25223] Statically or dynamically linked to the VC++runtime ? or how Python install fails on Vista despite the VC redist packages - api-ms-win-crt-runtime-l1-1-0.dll

[eryksun]

eryksun added the comment:

> Dependency Walker doesn't know how to resolve those DLLs on 
> any platform - Win10 looks exactly the same. 

On older systems the api-ms-win-crt-* DLLs should be physically installed in 
System32, so Dependency Walker should find them if they exist. For example, on 
a Windows 7 box:

>dir /b C:\Windows\System32\api-ms-win-crt*.dll
api-ms-win-crt-conio-l1-1-0.dll
api-ms-win-crt-convert-l1-1-0.dll
api-ms-win-crt-environment-l1-1-0.dll
api-ms-win-crt-filesystem-l1-1-0.dll
api-ms-win-crt-heap-l1-1-0.dll
api-ms-win-crt-locale-l1-1-0.dll
api-ms-win-crt-math-l1-1-0.dll
api-ms-win-crt-multibyte-l1-1-0.dll
api-ms-win-crt-private-l1-1-0.dll
api-ms-win-crt-process-l1-1-0.dll
api-ms-win-crt-runtime-l1-1-0.dll
api-ms-win-crt-stdio-l1-1-0.dll
api-ms-win-crt-string-l1-1-0.dll
api-ms-win-crt-time-l1-1-0.dll
api-ms-win-crt-utility-l1-1-0.dll

In Windows 10 these DLLs are an API Set contract; they don't actually exist in 
the filesystem. For example, on Windows 10 GetModuleHandle for all of these 
DLLs returns a handle to ucrtbase.dll, whereas on Windows 7 each is a uniquely 
loaded module.

[issue24820] IDLE themes for light on dark

[Terry J. Reedy]

Terry J. Reedy added the comment:

For me, Idle comes with one light theme, under 2 names. I don't know what 
happens on Mac.  Let us add one dark theme as Idle Dark, before 3.4.4 if 
possible.

We can later consider whether to add more light and dark built-in themes. But I 
think more important would be to add the ability to change at once the 
background of all elements that use the default (normal) background. I believe 
you have mentioned that one might want to change white to an off-white.  Cobalt 
is an off-black, but someone might prefer black black, or the slightly bluer 
background of Windows Power Shell.  We should not have multiple themes just for 
background variations.

[Brett Cannon]

Brett Cannon added the comment:

Just so Steven knows, I'm still thinking about whether I want to accept the 
patch (and waiting to see if anyone else has an opinion =). I did realize that 
the patch as it stands does not add the found module as an attribute on the

[issue15347] IDLE - does not close if the debugger was active

[Mark Roseman]

Mark Roseman added the comment:

Doing some testing using "-n". Various close/quit scenarios are either 
disallowed or broken as it turns out. I found that removing the "interacting" 
check on close improved the matter quite substantially, so that I could quit 
when the debugger was sitting waiting for input, without hangs etc.

Have attached remove-interacting-debugger.patch (which can be applied on top of 
fix-mainloop2.patch (from #24455, which includes the changes in 
fix-nested-mainloop.patch for this bug).

[issue25175] Documentation-Tkinter Clarify module spelling change in Python 3 docs

[Terry J. Reedy]

Terry J. Reedy added the comment:

Martin> Normally the documentation doesn’t mention changes from Python 2

Right: forward notes in 2.7 doc, no backward notes in 3.x doc. The 2.7 doc has 
near the top "Note: Tkinter has been renamed to tkinter in Python 3. The 2to3 
tool will automatically adapt imports when converting your sources to Python 
3."  Perhaps this should be expanded to mention the other tkinter imports.

We collectively agreed that adding backward notes in 3.x docs is not needed for 
beginners who start with 3.x, and would actively confuse them with information 
most do not need. I think breaking this rule requires agreement of more than 
the nosy list here: at minimum, Georg Brandl and Serhiy Storchaka, but better 
pydev.

There are still occasional issues about removing 2.x mentions or, more likely 
now, revising leftover 2.x examples.  The OP is complaining about an example 
that was properly revised.  If a new 2.x note were added, someone might come 
along and remove it.

I agree with
Mark> Does this open a can of worms?
Just for tkinter, there is also "import tkFont" (2.x) versus "import 
tkinter.font" (3.x) and similar for other stuff in the 'tkinter' package.  
Consequently, the proposed note is incomplete.

Carol> the Tkinter project does start with a capital 'T'
I am not aware of a 'Tkinter project' separate from the tkinter module in the 
stdlib, maintained by various people, though current mostly by Serhiy.  In any 
case, the Python project starts with 'P' while the python binaries start with 
'p'.

The OP simply made a mistake; there is no bug in the 3.x doc.  The tkinter 
package (unlike idlelib) follows 3.x rules.  I think the issue should have been 
closed immediately as 'not a bug', and should be so closed now.

[issue25135] Deques to adopt the standard clearing procedure for mutable objects

[Tim Peters]

Tim Peters added the comment:

The only way to be certain you're never going to face re-entrancy issues in the 
future is to call malloc() directly - and hope nobody redefines that too with 
some goofy macro ;-)

In the meantime, stick to PyMem_Malloc().  That's the intended way for code 
holding the GIL to do lowest-level memory allocation.  Uses of 
PyMem_RawMalloc() should be extremely rare, typically only in contexts where 
Python internals _know_ the GIL isn't being held, and can't reasonably try to 
acquire the GIL.  It's already being used in a few contexts where it probably 
shouldn't be, and each such use needlessly complicates future changes.

If PyMem_Malloc() does grow re-entrancy issues in the future, deques will be 
the least of our problems.  I'd strongly oppose it before then.  It's 
_intended_ to be as low level as possible (it was created to begin with just to 
worm around cross-platform insanity when called with a 0 argument).

[issue25233] AssertionError from asyncio Queue get

[Guido van Rossum]

New submission from Guido van Rossum:

See https://github.com/python/asyncio/issues/265 and 
https://github.com/python/asyncio/issues/268. This looks like an important 
regression and we should fix it before 3.5.1 goes out.

The symptom is "AssertionError: queue non-empty, why are getters waiting?" from 
Queue.get or Queue.get_nowait. The first issue discusses the cause and a 
possible hack to fix it.

[issue25135] Deques to adopt the standard clearing procedure for mutable objects

[Raymond Hettinger]

Raymond Hettinger added the comment:

> I'm not sure that you understand what you are trying to do.

The goal is to avoid possible re-entrancy both now and in the future.  Since 
PyMem_RawMalloc is thread-safe and doesn't require the GIL to be held, it is 
guaranteed that there won't be a callback into regular Python that could mutate 
any of the data structures.

[issue24820] IDLE themes for light on dark

[Terry J. Reedy]

Terry J. Reedy added the comment:

Here is an Idle Dark theme that is the near-inverse of the standard Idle theme, 
with foreground colors tweaked just a bit to account for the background switch 
and its blue tint.  It otherwise retains the current color mapping.  What do 
you think?

That works fine, but then again the ticket only concerns the context menu of 
_shortcuts_ to Python files. Opening Python files directly, either via "Edit

beginning.

Yes I am interesting in making a patch for auto-completing module names. I’ll 
leave it on my to-do list, but don’t expect it overnight. :) My code does some 
rough parsing of Python syntax, but maybe that is not needed for “import x”, 
though it might be needed to support module attributes for “from x import y”.

[issue25237] Add doc for tkinter commondialog.Dialog and subclasses

[Terry J. Reedy]

New submission from Terry J. Reedy:

As noted in #15346, several modules are not documented except in the code.  
Having just had to do that for #25173, I would like there to be a page for 
commondialog.Dialog and its subclasses, messagebox.Message and 
colorchooser.Chooser, and the associated module functions.  I hope to submit a 
.rst file for review if no one else does so.  My plan is to copy from web pages 
produced by the pydoc server, add markup, and edit.

[issue25237] Add doc for tkinter commondialog.Dialog and subclasses

[Terry J. Reedy]

Terry J. Reedy added the comment:

Side issue: Dialog has this:
# we need a dummy widget to properly process the options
# (at least as long as we use Tkinter 1.63)
w = Frame(self.master)

Do you know what 'Tkinter 1.63' refers to?  In 2.7, Tkinter.__version__ is 
'$Revision: 81008 $'.  If self.master is not None, I would expect that it can 
be used in
s = w.tk.call(self.command, *w._options(self.options))
s = self._fixresult(w, s)

[issue25135] Deques to adopt the standard clearing procedure for mutable objects

[STINNER Victor]

STINNER Victor added the comment:

"Victor, I was thinking of switching to PyMem_RawMalloc instead of 
PyMem_Malloc.  The advantages are that there are guaranteed to be no 
side-effects, the GIL doesn't need to be held, and there is less overhead.  Are 
there any disadvantage I should know about?"

For me, PyMem_Malloc() can be faster than PyMem_RawMalloc() because the GIL is 
held. In practice... both function are very thin wrapper to malloc(), so it's 
exactly the same :-) In Objects/obmalloc.c, you have:

#define PYRAW_FUNCS _PyMem_RawMalloc, _PyMem_RawCalloc, _PyMem_RawRealloc, 
_PyMem_RawFree
...
#define PYMEM_FUNCS PYRAW_FUNCS

So PyMem_Malloc() and PyMem_RawMalloc() are *currently* exactly the same.

I'm not sure that you understand what you are trying to do. If you expect 
better performances, you should try to use PyObject_Malloc() instead, to 
benefit from the fast Python allocator for small allocations (512 bytes and 
less).

Serhiy, I'm still considering your patch.  I have a strong aversion to putting 
a big block on the stack and don't like having to do a full block memcpy every 
time a deque is cleared on deallocation.  If you don't see an actual bug in 
patch 2, I'm inclined to use that approach (especially since the popping 
fallback approach will likely never be called in practice).

[issue25231] Argparse module and escape sequence (special symbols) in argument value

[Ondřej Profant]

New submission from Ondřej Profant:

I am trying to put tabulator '\t' into argument value. 

Minimal working example:


#!/usr/bin/env python3

import argparse

def main():
parser = argparse.ArgumentParser()
parser.add_argument('-f', '--foo', default="test", help="test")
args = parser.parse_args()

print("Argument foo is: " + args.foo + "|")
print("Tabulator usage: |\t|")

if __name__ == '__main__':
main()


My attempts:
./test.py -f \t
./test.py -f '\t'
./test.py -f "\t"

But this is not functional. Is there way to put special characters into 
argument?

[issue25231] Argparse module and escape sequence (special symbols) in argument value

[Martin Panter]

Martin Panter added the comment:

As far as I know “argparse” takes arguments straight from the command line 
without interpreting any escape sequences. Perhaps you should look up how to 
pass a literal tab on the command line, but this is nothing specific to do with 
Python. E.g. in the Bash shell the following might work:

$ echo $'a\tb'  # Bash specific syntax
a   b
$ echo "$(printf 'a\tb')"  # Any Posix shell
a   b
$ echo "a   b"  # Ctrl+V, Tab for literal tab to bypass completion
a   b
