The macOS system tk, 8.5.9, is over a decade old and buggy.  python.org python

[issue46117] tk could not refresh auto in mac os

[asper]

asper  added the comment:

Thank you for your reply. The phenomenon is still exist on mac os, when I add 
'root.update_idletasks()'. The version of tk on mac os is 8.5.9, the version of 
tk is show 8.6.12 from the enviroment of python3.10.
Now, I use lower() and lift() to switch two frame in tkinter, it works well.

[issue46095] Warning about iterate/modify has unwarranted detail

[Raymond Hettinger]

Raymond Hettinger  added the comment:

I think this note can be removed.  The tutorial now has coverage of mutating 
while iterating.  That is the correct place for discussion of looping 
techniques.

The part about the "internal counter" needs to be rewritten and moved to 
stdtypes.rst section on Sequence types.  Here is a first draft:

"Forward and reversed iterators over sequences access values using an index.  
That index will continue to march forward (or backward) even if the underlying 
sequence is mutated.  The iterator terminates only when an IndexError or 
StopIteration is encountered (or when the index drops below zero)."

Sequence iterators are roughly equivalent to:

def seqiter(seq):
i = 0
while True:
try:
yield seq[i]
except (IndexError, StopIteration):
break
i += 1

[Pablo Galindo Salgado]

Pablo Galindo Salgado  added the comment:

This is a known issue for recursive descendent parsers. The only thing we can 
do here is somehow limit the maximum stack depth of the C stack, but that can:

* Slow down the parser.
* Limit valid expressions that otherwise won't segfault.
* Still don't work in certain systems.

Pablo Galindo Salgado  added the comment:

That is weird, but can happen for example if some pthread of some c extensión 
for example picks up the Gil, causing a new PyThreadState to be created and 
linked but has not called into Python yet.

Basically, an external native thread that calls 
PyGILState_Ensure leaves a thread state with these characteristics.

Guido van Rossum  added the comment:

A thread without a frame looks like a natural end case when you consider the 
frames as a linked list. Could it be that exec()/eval() run in the current 
frame, and if there isn't a frame, they refuse to run? (Sorry, I don't recall 
anything more specific without going hunting through old code.)

[issue46118] Migrate importlib.resources into a package

[Jason R. Coombs]

Jason R. Coombs  added the comment:

Compatibility considerations: 

- importlib.readers and importlib.simple are public, so probably need aliases.
- Same abc classes.

Should we embark on an effort to migrate users to the new names in 
`importlib.resources`, or simply leave the `importlib.{mod}` names as 
preferred? My instinct is to do the former, mainly because then the names would 
be congruent between `importlib.resources` and `importlib_resources`. But I'm 
also reluctant to introduce a deprecation (even deferred) comparable to what 
happened with `collections.abc`.

[issue46118] Migrate importlib.resources into a package

[Jason R. Coombs]

New submission from Jason R. Coombs :

The importlib.resources module has several modules on which it relies 
(_adapters, _legacy, simple) and some classes in other modules shared by other 
parts of importlib (namely abc).

Because these implementations overlap, it adds difficulty in maintaining the 
`importlib_resources` backport, which must maintain these modules but keep them 
separate from the unrelated functionality in other parts of importlib.

In an earlier refactoring, `importlib.metadata` was refactored into its own 
package (https://github.com/python/cpython/pull/25565). This refactoring had 
benefits of making it clearer which functionality of importlib was related to 
metadata and which was not.

I'd like to do the same for importlib.resources.

The main complicate

[issue46109] Separate resources and abc docs from other importlib docs

[Jason R. Coombs]

Jason R. Coombs  added the comment:

My main motivation for moving `.abc` was because it contains classes 
exclusively relevant to `.resources` (those also present in 
`importlib_resources.abc`. I want to explore moving those classes to the 
resources documentation so they're available together and maintained 
independently.

Other classes in `.abc` are relevant to the import system more generally, so 
maybe should stay in the main docs.

[issue20741] Documentation archives should be available also in tar.xz format

[Éric Araujo]

Éric Araujo  added the comment:

tar is modular and depends on optional external programs to handle compression 
(tar itself does archival only).

gzip is still common, and xz has largely replaced bz2 these days.
I would expect it to be installed on most systems.

(For HTTP compression there are new competitors, brotli and zstd, but I haven’t 
seen these used to compress files.)

[Terry J. Reedy]

Terry J. Reedy  added the comment:

https://docs.python.org/3/download.html says a) tar.bz2 can be read by the tar 
program, which I presume is true also of tar.xz.  So there is no issue of 
*needing* two separate programs.  It also claims "The .tar.bz2 archives provide 
the best compression and fastest download times."  This only need be true, if 
it is, for the doc formats, as opposed to python code.  In the absence of at 
least 2 requests from *nix consumers of the archives, why even think of 
changing?

[issue46117] tk could not refresh auto in mac os

[Terry J. Reedy]

Terry J. Reedy  added the comment:

IDLE is neither the Python it is written it, nor the tkinter module it depends 
on.  For this tracker, this is at most a tkinter on macOS 12 issue.  But I 
suspect that it is an issue of the 3rd party tcl/tk on the new macOS version.  
There have been others.  Perhaps someone else can test on earlier macOS.  (I 
verified that the code works as intended on Win 10 with Tk 8.6.12.)

I am not sure of your intention in half-closing this issue.  But, does adding 
'root.update_idletasks()' to the end of 'change' make any difference?

Oh to counter my own proposal: formats should not be removed without warnings, 
there are probably downstream tools that expect specific URL patterns and

I don’t think that consistency or standardization really applies here, it’s not 
like there are tools that want to process both source and doc archives and are 
broken by the difference in formats.

It could be useful to review the formats used and decide if they are still the 
best choices (maybe zip for universality, tar + modern and well-supported 
compression for size), but consistency for consistency’s sake is needless churn.

[issue46090] C extensions can't swap out live frames anymore

[Brandt Bucher]

Brandt Bucher  added the comment:

Also, it appears that in earlier versions of CPython, it was okay to set 
tstate->frame = NULL. Some of Greenlet's tests *seem* to be doing this 
(although it also possible that my current scaffolding has just broken 
Greenlet).

Does anybody know off the top of their head what it means to set a NULL frame? 
I can dig around through the old code and see what the interpreter does when 
that happens, but it seems pretty nonsensical to me. Is it something that only 
happens during interpreter/thread initialization/shutdown? Or maybe it keeps 
that thread from becoming active?

- Clear and pop tstate->cframe->current_frame and all of its linked 
predecessors.
  - These should all belong to the same CFrame, right?
- Push copies of the new InterpreterFrame and all of its predecessors (bottom 
to top, of course), and update all of the PyFrameObjects to point to the new 
copies.
  - I'm just going to assert(f->f_owns_frame) before copying each of these (and 
set it to 0, after). I don't think it could ever be valid to stick a new copy 
of an active frame onto the top of the stack?
- Set tstate->cframe->current_frame to the new, top InterpreterFrame.
  - If my understanding of the new CFrame mechanics is correct, I don't think 
we'd need to touch the C stack at all? Maybe I'm missing something, though... 
if we do need to change the size of the C stack, this whole thing becomes a 
*lot* more painful.

Anyone see any obvious flaws here? I'm new to a lot of this code, so any 
guidance would be appreciated.

[issue45383] PyType_FromSpec API fails to use metaclass of bases

[Sebastian Berg]

Sebastian Berg  added the comment:

Btw. huge thanks for looking into this!  Let me know if I can try to help out 
(I can make due with static metatypes, but my story seems much clearer if I 
could say: Well with Py 3.11 you can, and probably should, do it dynamically.). 
 I had lost a lot of time chasing "metaclass should just work" followed by "but 
I can't get it right without bad hacks".

And now the solution seems fairly clear, which is amazing :)!

[issue46109] Separate resources and abc docs from other importlib docs

[Eric Snow]

Eric Snow  added the comment:

FWIW, one benefit to having everything in one doc (instead of one doc per 
submodule) is that it's a little easier to see the bigger picture.  This is 
particularly important for folks interested in customizing the import system 
(rather than just interacting with it).

However, they would probably be better served by an explicit section on how to 
customize the import system.  The language reference provides the info but its 
focus is to specify rather than to guide.  So it may make sense to have a 
dedicated section to at least cover the supported customization approaches (at 
a high level).

This would definitely be covered by a separate issue but it makes less sense if 
we don't move the submodules to their own docs.

[issue46109] Separate resources and abc docs from other importlib docs

[Eric Snow]

Eric Snow  added the comment:

+1 to splitting out the importlib.resources docs

I'm mostly +1 for splitting out the others (.abc, .machinery, .util) too, not 
just .abc.

Regardless, a ToC at the top of the main page which identifies the submodules 
(and provides a brief summary for each) would be extra helpful.  I suppose that 
could be helpful regardless of whether or not we move submodule docs out.

[issue45383] PyType_FromSpec API fails to use metaclass of bases

[Sebastian Berg]

Sebastian Berg  added the comment:

Well, what we need is a way to say: I am calling `type.__new__` (i.e. 
PyType_FromSpec) on purpose from (effectively) my own `mytype.__new__`?

That is, because right now I assume we want to protect users from calling 
PyType_FromSpec thinking that it is equivalent to calling `class new(base)` 
when it may not be if base is a metaclass.  So calling `PyType_FromSpec` might 
refuse to work if it finds a custom `metaclass.__new__` (init?).

I don't really see that it matters if we only support effectively this from C:
```
class MyMetaClass(type):
def __new__(cls, *args, **kwargs):
self = type.__new__(...)  # this is PyType_FromSpec
# more stuff
```
So, I thought telling `PyType_FromSpec` that we are "inside" a custom `__new__` 
is sufficient and that even as a flag passed as part of the spec could be 
enough.
But... I agree that I do not quite see that it would be pretty, so it probably 
was a bad idea :).

Plus, if you add a new method it should also solves the issue of setting the 
`tp_type` slot to the metaclass explicitly when it is not implicit by 
inheritance (which is the only thing I care about).
(PyType_FromSpec and PyType_ApplySpec will still need to do the work of 
resolving the metaclass from the base classes, though.)

Yes, the example also does not segfault for me either (also with Python 3.8.12 
I have now as `python3.8`), so this was likely only happening in the more 
complex setup, and/or maybe with some specific version of readline back then.

[issue45383] PyType_FromSpec API fails to use metaclass of bases

[Sebastian Berg]

Sebastian Berg  added the comment:

Fully, agree!  In the end, `PyType_FromSpec` replaces `type.__new__()` (and 
init I guess) when working in C.  In Python, we would call `type.__new__` 
(maybe via super) from the `metatype.__new__`, but right now, in C, the 
metatype cannot reliably use `PyType_FromSpec` in its own `metatype.__new__` to 
do the same.

I agree with the scenarios:
* If we do not have a custom `metatype.__new__` (init?) then `PyType_FromSpec` 
should have no reason to refuse doing the work, because nothing can go wrong.
* If we do have a custom `tp_new` the user has to provide C API to create the 
metaclass instance.  But they still need a way to call `type.__new__` in C 
(i.e. get what `PyType_FromSpec` does, and promising to do the rest).

`PyType_ApplySpec` would provide that way to create a custom `metatype.__new__` 
in C when `PyType_FromSpec()` would otherwise reject it to make the first 
scenario safe.
A flag probably can do the same.  I have no preference, `ApplySpec` seems great 
to me.

[issue45383] PyType_FromSpec API fails to use metaclass of bases

[Petr Viktorin]

Petr Viktorin  added the comment:

I don't see how instantiating a metaclass with non-default tp_new would work if 
you don't know some details about the specific metaclass. So IMO we can we 
limit ourselves to scenarios where either:
1) the metaclass uses default tp_new, or
2) the code that creates the class knows about the metaclass

For case 2), we could leave allocation to the calling code, and add an API 
function that does the rest of the work of applying the spec. Something like:

/* Create a metaclass */
metatype_spec = {stuff};
metatype = PyType_FromSpecAndBases(&metatype_spec, &PyType_Type);
/* Create a type */
type_spec = {other_stuff};
newtype = alloc_metatype();
PyType_ApplySpec(newtype, &type_spec);

PyType_ApplySpec would assert PyType_Ready wasn't called before, and call it 
after filling in the name, slots, etc.
The metatype could disable its tp_new to disallow PyType_FromSpec (and Python 
__new__), effectively enforcing "using_metaclass_cinit_pretty_promise_please".

There could be a slot for code to run at the end of PyType_ApplySpec -- the 
"PyArray_InitDTypeFromSpec" in your pseudocode.


That seems better than calling the metaclass, but to answer questions on that 
idea:

>> - basicsize/itemsize could be allowed with __basicsize__/__itemsize__ in the 
>> dict.
>Do we need this?  I need the basicsize of the metaclass, but that of the class 
>seems fixed/OK?

That's the size of the instance. One more level down :)

>> - members could theoretically be copied to individual descriptors; there 
>> doesn't seem much need for keeping tp_members around.
> But a Python MetaClass (that the author may not even realize about) might 
> need access to these to work properly?
> A bit far fetched, but...

Seems very far-fetched to me. IMO these, like e.g. tp_methods, should only be 
used as arguments for the code that puts the descriptors in __dict__. How the 
descriptors got there is a detail, the class doesn't need to use tp_members 
(nor advertise that it does).

entry1 = ttk.Entry(root)
entry2 = ttk.Entry(root)

root.mainloop()

I run the script in mac os 12.1, use python3.10 download from python.org. when 
the main window show, I change it's size, and press the   "change" button, the 
script change the label'text from "Name" to "Name2".When press the button 
again, the label'text from "Name2" to "Name". but the label cannot refresh the 
text, it show nothing. when I move the mouse, the text showed immediately. 
The script run normally on windows system.
I use the grid_remove() and grid() to switch frame.

On linux/glibc you do not have to do this, there is a

for the not posix_spawn case, interate over /proc/self/fd and set the CLOEXEC

[issue46114] OpenSSL deprecated OpenSSL_version_num() since version 3.0.0

[Christian Heimes]

Christian Heimes  added the comment:

The test case does not work for OpenSSL >= 3.0.1. The test assumes that the 
version starts with M.NN.FF, but OpenSSL 3 uses M.NN.PP. The FF (fix) part is 
always 00. The issue didn't show up before because fix and patch level were 0 
for 3.0.0 alphas and betas.

[issue46108] Enum repr() incorrect when mixed with non-__new__ data types

[Ethan Furman]

Ethan Furman  added the comment:

Thanks, test added.  I also updated the title.

Code updated to treat any __repr__s as affecting the display of the member 
value instead of the member itself (i.e. the "<...: %r>" portion).  if a user 
actually wants to change the member repr they can assign it when creating the 
Enum:

class Entries(Foo, Enum):
ENTRY = 1
__repr__ = Foo.__repr__

assert repr(Entries.ENTRY1) == 'Entries(a=1)'

[issue46115] Interrupting subprocess.popen in recursive calls by KeyboardInterrupt causes Fatal Python error.

[Xinmeng Xia]

New submission from Xinmeng Xia :

Popen works when stdio fds are available. However, when interrupting popen in a 
recursive function call. The Python interpreter reports a Fatal Python error.

test.py

import subprocess
import os
import sys


def test_small_errpipe_write_fd():
new_stdout = os.dup(1)
try:
os.close(1)
subprocess.Popen([sys.executable, '-c', 
"print('AssertionError:0:CLOEXEC failure.')"]).wait()
finally:
os.dup2(new_stdout, 0)
os.dup2(new_stdout, 1)
test_small_errpipe_write_fd()

KeyboardInterrupt
---

Reproduce step:
1. run test.py in the console
2. use "Ctrl C" to interrupt the program

If typing a "Ctrl C", the program does not stop and no error is reported. Just 
type "Ctrl C" constantly. Sometimes, it need 5 or 6 "Ctrl C" to reproduce this 
bug.

[issue46112] PEP 8 code format

[Steven D'Aprano]

Steven D'Aprano  added the comment:

> not complied with the PEP-8 formatting.

PEP 8 says:

"Some other good reasons to ignore a particular guideline:

3. Because the code in question predates the introduction of the guideline and 
there is no other reason to be modifying that code."

So PEP 8 itself tells us that legacy code that ignores the style guidelines is 
already compliant with PEP 8.

[issue22047] Deprecate unsupported nesting of argparse groups

[László Attila Tóth]

László Attila Tóth  added the comment:

Hi, according to the group update the _MutuallyExclusiveGroup should have an 
add_argument_group() call with the deprecation warning, but that method is 
missing in commit 30322c497e0b8d978f7a0de95985aac9c5daf1ac.

[issue46112] PEP 8 code format

[Serhiy Storchaka]

PEP 8 is a guide for writing new code. It does not require rewriting the old 
code. In fact, patches with mass reformatting of the stdlib code have always 
been rejected.
