[issue44571] itertools: takedowhile()

[paul rubin]

paul rubin  added the comment:

Oh wow, before_and_after will go into the itertools module per that patch?  I 
found this issue while looking for a way to this, but had written the following 
implementation:

def span(pred, xs):
# split xs into two iterators a,b where a() is the prefix of xs 
# that satisfies the predicate, and b() is the rest of xs.  
# Similar to Data.List.Span in Haskell. 

ixs = iter(xs)
t = None
def a():
nonlocal t
for x in ixs:
if pred(x): yield x
else: break
t = x
def b():
return itertools.chain([t], ixs)
return a, b

def tspan():  # test
xs = [1,3,5,2,4,6,8]
def odd(x): return x%2==1
# This should print [1,3,5] then [2,4,6,8]  
for p in span(odd, xs):
print(list(p()))

[issue45428] py_compile fails to read filenames from stdin

[Graham Inggs]

New submission from Graham Inggs :

py_compile fails to read a list of filenames to be compiled from standard 
input.  This is a regression in 3.10.

example

files-to-compile.txt is a text file containing hello.py and goodbye.py on 
separate lines.  hello.py and goodbye.py must exist.

python3.10 -m py_compile -

[issue45415] Assert oparg < INSTR_OFFSET()

[STINNER Victor]

STINNER Victor  added the comment:

Steve:
> Also +Victor, because I think we should switch back to debug builds in CI in

Ken Jin:
> So I don't see why Windows is special.

The Python test suite is way slower on Windows when Python is built in debug 
mode: 19 min 41 sec (debug) instead of 12 min 19 sec (release) on Windows x64: 
1.6x slower.

* https://bugs.python.org/issue45115#msg401141
* https://github.com/python/cpython/pull/28181

I would prefer to not make our workflow slower. IMO it's ok to miss a few bugs 
in pre-commit checks, and only catch them on Windows debug buildbots. In my 
experience, it happens less than once per months. It's more like 2 or 3 times 
per year.

[issue45429] [Windows] time.sleep() should use CREATE_WAITABLE_TIMER_HIGH_RESOLUTION

[STINNER Victor]

New submission from STINNER Victor :

In bpo-21302, the Windows implementation of time.sleep() was modified to use a 
waitable timer:

New changeset 58f8adfda3c2b42f654a55500e8e3a6433cb95f2 by Victor Stinner in 
branch 'main':
bpo-21302: time.sleep() uses waitable timer on Windows (GH-28483)
https://github.com/python/cpython/commit/58f8adfda3c2b42f654a55500e8e3a6433cb95f2

It now calls the functions:

* CreateWaitableTimerW()
* SetWaitableTimer()
* WaitForMultipleObjects()

While SetWaitableTimer() has a resolution of 100 ns, the timer has a resolution 
of 15.6 ms in practice.

We could use the undocumented CREATE_WAITABLE_TIMER_HIGH_RESOLUTION flag with 
CreateWaitableTimerEx(). See: https://bugs.python.org/issue21302#msg403550

[issue44571] itertools: takedowhile()

[paul rubin]

paul rubin  added the comment:

Bah, the above doesn't work in the cases where the iterator is empty or 
(different symptom) where the tail part is empty.  Rather than posting a 
corrected version (unless someone wants it) I'll just say not to use that code 
fragment, but that the intended API still looks reasonable.  I do support 
having some kind of solution but don't want to keep stretching out an already 
closed discussion unless people think there is more to say.

[issue45431] [C API] Rename CFrame or hide it to only export names starting with Py

[STINNER Victor]

New submission from STINNER Victor :

#include  should only define names which start with "Py" (Py, _Py, 
PY, _PY), but it now defines a structure called "CFrame" in 
Include/cpython/pystate.h.

We should either make the whole PyThreadState structure private (move it to the 
internal C API), or rename CFrame (to PyCFrame?).

[issue45427] importlib.readers.MultiplexedPath

[David Rajaratnam]

David Rajaratnam  added the comment:

Thanks for the quick response. I think the attached file shows the issue. 

In the directory where you download and run this file create a sub-directory 
'data'. Then running the file creates the output (note: I've truncated the path 
name):

> Traverse data: MultiplexedPath('<>/data') ( 'importlib.readers.MultiplexedPath'>)

I think the idea behind MultiplexedPath() is that it merges together multiple 
base/root directories so even though in this case it is a single path it 
wouldn't necessarily be the case in general. So while it makes sense that for 
some MultiplexedPath object X that str(X) isn't itself a proper directory path, 
however, there seems to be no method/property to access these root paths.

Note: Traverable.iterdir() iterates over the files/sub-directories in the 
root(s) so doesn't return the root path(s) themselves.

A further note. If you add a file `data/__init__.py` then data is now a package 
and running the code this time returns a PosixPath object (on a posix system): 

> Traverse data: <>/data ()
> X: <>/data/__init__.py ()
> X: <>/data/__pycache__ ()

[issue45431] [C API] Rename CFrame or hide it to only export names starting with Py

[Mark Shannon]

Mark Shannon  added the comment:

Struct names aren't exported as symbols.

$ nm ./python | grep CFrame

So, I assume that are worried about name clashes for code that has
#include "Python.h".


Isn't the threadstate struct supposed to be opaque?
If so, then shouldn't it be moved to an internal header?


I don't want to add a "Py" prefix to the name of the CFrame struct.
The names of the various frames are confusing enough, without adding a "Py" 
prefix to something that isn't a Python frame.

[issue44828] Using tkinter.filedialog crashes on macOS Python 3.9.6

[Marc Culler]

Marc Culler  added the comment:

Hi Ronald,
There is no calendar scheduling for Tk releases.  Don Porter decides when they 
happen.  But I think we are due for another one soonish.  In case it doesn't 
happen before the next Python release I will attach the patch file for commit 
a32262e9.  (Note that this is subject to change - I still need to test on 
10.14.) I believe that this patch is completely self-contained and can be 
applied to the 8.6.11 release.

(Hint: Tk uses fossil as its SCM system.  On a fossil timeline, clicking any 
two nodes generates their diff.  The Tk timeline is at 
https://core.tcl-lang.org/tk/timeline)

[issue45356] Calling `help` executes @classmethod @property decorated methods

[Randolf Scholz]

Randolf Scholz  added the comment:

Dear Raymond,

I think decorator chaining is a very useful concept. At the very least, if all 
decorators are functional (following the `functools.wraps` recipe), things work 
out great -- we even get associativity of function composition if things are 
done properly!

The question is: can we get similar behaviour when allowing decoration with 
stateful objects, i.e. classes? This seems a lot more difficult. At the very 
least, in the case of `@classmethod` I think one can formulate a 
straightforward desiderata:

### Expectation

- `classmethod(property)` should still be a `property`!
- More generally: `classmethod(decorated)` should always be a subclass of 
`decorated`!

Using your pure-python versions of property / classmethod from 
, I was able to write down a 
variant of `classmethod` that works mostly as expected in conjunction with 
`property`. The main idea is rewrite the `classmethod` to dynamically be a 
subclass of whatever it wrapped; roughly:

```python
def ClassMethod(func):
  class Wrapped(type(func)):
  def __get__(self, obj, cls=None):
  if cls is None:
  cls = type(obj)
  if hasattr(type(self.__func__), '__get__'):
  return self.__func__.__get__(cls)
  return MethodType(self.__func__, cls)
  return Wrapped(func)
```

I attached a full MWE. Unfortunately, this doesn't fix the `help` bug, though 
it is kind of weird because the decorated class-property now correctly shows up 
under the "Readonly properties" section. Maybe `help` internally checks 
`isinstance(cls.func, property)` at some point instead of 
`isinstance(cls.__dict__["func"], property)`?

### Some further Proposals / Ideas

1. Decorators could always have an attribute that points to whatever object 
they wrapped. For the sake of argument, let's take `__func__`.
   ⟹ raise Error when typing `@decorator` if `not hasattr(decorated, 
"__func__")`
   ⟹ Regular functions/methods should probably by default have `__func__` as a 
pointer to themselves?
   ⟹ This could hae several subsidiary benefits, for example, currently, how 
would you implement a pair of decorators `@print_args_and_kwargs` and 
`@time_execution` such that both of them only apply to the base function, no 
matter the order in which they are decorating it? The proposed `__func__` 
convention would make this very easy, almost trivial.
2. `type.__setattr__` could support checking if `attr` already exists and has 
`__set__` implemented.
  ⟹ This would allow true class-properties with `getter`, `setter` and 
`deleter`. I provide a MWE here: 

3. I think an argument can be made that it would be really, really cool if `@` 
could become a general purpose function composition operator?
  ⟹ This is already kind of what it is doing with decorators
  ⟹ This is already exacltly what it is doing in numpy -- matrix multiplication 
\*is\* the composition of linear functions.
  ⟹ In fact this is a frequently requested feature on python-ideas!
  ⟹ But here is probably the wrong place to discuss this.

New submission from Paul :

here is my test file:

when I then try 'python test.py ^test' the ^ character is stripped away, this 
doesn't happen on Linux. This also doesn't happen if I put ^test in quotes 
(only ") the ' quotes don't work

[issue44828] Using tkinter.filedialog crashes on macOS Python 3.9.6

[Guy DeStefano]

Guy DeStefano  added the comment:

Please help me.  Am new to Python, and don't know enough to post here, but I 
will try.  Have written a couple of programs that use tkinter, especially 
tkinter.filedialog.askopenfilenames, and as everyone else mine has quit working 
since Monterey. I have a macOS Monterey version beta( 21A5543b ).  Am 
using Python3 v3.10.0.  Have tried using v3.11.0a1, but could not even compile, 
says that import ( PIL ) does not exist.  Put back v 3.10.0 and am back to no 
filedialog.  Is Apple attempting to do away with the file API.  Just asking. 
Thank you.

No, Apple is not going to do away with their NSOpenPanel.  There is always some 
churn when they release a new OS.  Subtle changes to APIs can occur with no 
warning and no documentation.  Sometimes they are bugs. Sometimes they 
disappear when the OS is released.  Sometimes they are permanent.  I would not 
recommend using a beta version of the OS to develop your tkinter app.

[issue45433] libpython should not be linked with libcrypt

[Mike Gilbert]

New submission from Mike Gilbert :

In https://bugs.python.org/issue44751, crypt.h was removed from Python.h. This 
would imply that libpython is not meant to expose any crypt-related symbols.

In fact, it looks like libpython does not use crypt() or crypt_r() at all. 
These are only used by cryptmodule.

In configure.ac, we have this this logic to determine if crypt_r() is available:

```
# We search for both crypt and crypt_r as one or the other may be defined
# This gets us our -lcrypt in LIBS when required on the target platform.
AC_SEARCH_LIBS(crypt, crypt)
AC_SEARCH_LIBS(crypt_r, crypt)

AC_CHECK_FUNC(crypt_r,
  AC_COMPILE_IFELSE([AC_LANG_PROGRAM([[
#define _GNU_SOURCE  /* Required for crypt_r()'s prototype in glibc. */
#include 
]], [[
struct crypt_data d;
char *r = crypt_r("", "", &d);
]])],
[AC_DEFINE(HAVE_CRYPT_R, 1, [Define if you have the crypt_r() function.])],
[])
)
```

The AC_SEARCH_LIBS macro adds "-lcrypt" to LIBS, and this gets passed down to 
the link command for libpython. This is probably not intentional.

The HAVE_CRYPT_R value is used in _cryptmodule.c. setup.py performs its own 
check for libcrypt when building the module.

I think the value of LIBS should be saved before the AC_SEARCH_LIBS calls and 
restored after the AC_CHECK_FUNC call. I have tested this locally on Gentoo 
Linux, and it seems to work fine.

I will work on a pull request.

[issue45253] mimetypes cannot detect mime of mka files

[Andrei Kulakov]

Andrei Kulakov  added the comment:

mkv (matroska) is not registered with IANA here: 
http://www.iana.org/assignments/media-types/media-types.xhtml

Therefore according to the comment in mimetypes.py, it should not be added.

Also note that .mkv is also not in mimetypes.py, so it's being loaded from your 
system's mime types, so if you want .mka to work as well, make sure it's 
registered on your system rather than in Python's mimetypes.py .

I will close this as not a bug, please comment here if you think it should stay 
open.

Well, it's scary of use functions which are documented as:

 * Caution:
 *This isn't reliable.  See Py_OVERFLOWED comments.
 *X and Y may be evaluated more than once.

[issue45405] configure fails on macOS with non-Apple clang version 13 which implements --print-multiarch

[Gregory Szorc]

Gregory Szorc  added the comment:

Note that this issue isn't macOS specific: you will get the same failure when 
cross-compiling targeting Linux. e.g. --build=x86_64-unknown-linux-gnu 
--host=i686-unknown-linux-gnu.

Can you be more specific? This particular issue isn't about cross-compiling. 
It's just about building for macOS on macOS. Under what circumstances is there 
a problem when trying to build one of the supported cross-compilation targets 
and does this proposed change fix that problem or create a new problem?
