This bug is valid, that macro and likely others aren't up to best practices.

[issue43001] python3.9.1 test_embed test_tabnanny failed

[Terry J. Reedy]

Terry J. Reedy  added the comment:

A 300 KB file of unknown type that has to be downloaded and opened with an 
unknown program is pretty useless.  Please state system/OS, exact Python 
release, command run, and copy-paste the errors here on the web page.

I do not see test_embed or test_tabnanny errors on Windows or Mac.  Are you 2 
on *nix?

For test_embed, all tests are skipped for me because _testembed.exe does not 
exist.  I am guessing that this is normal since the first line of the file says 
# Run the tests in Programs/_testembed.c (tests for the CPython embedding APIs)
This suggests that it should never fail when running the test suite normally.  
Victor?

[issue27640] Add --disable-test-modules configure option to not build nor install tests

[Eli Schwartz]

Eli Schwartz  added the comment:

I have a slightly different interest in declining to install tests... Arch 
Linux provides the tests as a split subpackage with currently some hacky shell 
globbing to delete the tests after make install, then do a second libinstall 
and delete everything but the tests.

It would be more convenient if we had a Makefile option to install the tests 
separately.

It's now possible to disable installing tests with a filthy hack: make install 
TEST_MODULES= TESTSUBDIRS=

However, it's not possible to similarly hack make libinstall LIBSUBDIRS=
Because it installs some toplevel stuff, then runs lib2to3.pgen2.driver on the 
grammar that got skipped by the LIBSUBDIRS= hack.

Thoughts on maybe splitting this up at install time? Would probably mean 
duplicating some of libinstall as testinstall...

I wrote a simple proxy with Python3.8 and Asyncio, but I found it couldn't

[issue38946] IDLE on macOS 10.15 Catalina does not open double-clicked files if app already launched

[Kevin Purrone]

Kevin Purrone  added the comment:

I have little experience posting in forums, so if this post is in the wrong 
place, please let me know. 

I am running Python3.9, with Apple OS 10.15.7
I was using IDLE successfully for a class in Python for the past three weeks, 
although I was rarely able to open a file by double clicking it. It actually 
worked a few times, but most of the time, nothing happened, and I would open 
IDLE first, and then open a file from its file menu. 

But today, IDLE will not open. When I click on the icon in the dock like I 
usually did, it seems to open for about .5 seconds, and then quits. Also, now 
when I double click on a .py file, IDLE will open for about .5 seconds and then 
quits. I reinstalled the package, but no change.

However, in terminal I can launch python with this command: python3.9. Then I 
can launch IDLE with this command: import idlelib.idle. The IDLE window opens, 
and I can open files from the file menu and they run as before. However, the 
title of the file menu is now "Python" where before, it was "IDLE"

[issue43182] TURTLE: Default values for basic Turtle commands

[Bruce Fuda]

New submission from Bruce Fuda :

Since Python is being taught to students of all ages and in particular younger 
kids (i.e. 6 - 10 yo) who are learning not just python, but many related things 
for the first time, the need to include values as arguments to basic Turtle 
functions like:

forward()
backward()
left()
right()

adds additional complexity. The natural starting point for these types of 
activities with kids is a transition from the physical world of devices such as 
the Bee-bot 
(https://www.tts-international.com/bee-bot-programmable-floor-robot/1015268.html)
 which have pre-defined lengths (i.e. 15cm) and turn angles (i.e. 90 degrees) 
so that they can focus primarily on sequencing and learning commands without 
the cognitive load of additional information.

It would be an ideal starting point for the forward(), backward(), left() and 
right() commands to be overloaded such that there is a default value. This 
reduces the cognitive load for young students, because it instead means they 
can focus on learning basic commands, sequencing and syntax without also 
needing to understand angles and relative lengths.

Suggestion would be to set a default value for movement (i.e. forward and 
backward) of 50, and default angles for turning (left and right) of 90 degrees.

This simple (and trivial) change would massively help thousands of students get 
started with Python, without in any way impacting existing use of Turtle.

[Daniel Moisset]

Daniel Moisset  added the comment:

@Ken: I've invited you to the repo. For tracking the WIP, 
https://github.com/dmoisset/cpython/tree/patma-docs

Do you want to see if you can base the reference/compound_stmts.rst changes in 
PEP 634? I'll try to fit a variant of the Appendix A of PEP 636 into the 
tutorial and make something up for the reference/lexical_analysis.rst (which 
needs  a section of soft keywords which are not in the PEP trilogy. Perhaps I 
can rescue something from PEP 622)

[issue43181] Python macros don’t shield arguments

[Vitaliy]

New submission from Vitaliy :

There is a lot of macros like:
#define PyObject_TypeCheck(ob, tp) \
(Py_IS_TYPE(ob, tp) || PyType_IsSubtype(Py_TYPE(ob), (tp)))
These work fine until an argument happen to contain a comma. That’s possible as 
a result of other macro’s expansion. E.g. if U(x) is defined as x,
PyObject_TypeCheck(ob, U(f(c)))
expands to
(Py_IS_TYPE(ob, f(c)) || ...)
but < and > aren’t treated as brackets by the preprocessor so Py_IS_TYPE is now 
invoked with 3 arguments instead of just 2, breaking module compilation.

As arguments are expected to be values, surrounding each with parentheses 
solves the problem. But there are many such macros so that’s not an one-line 
fix.

Note: the example is from PyGLM (simplified), it doesn’t compile on 3.9 due to 
this issue.

[issue43174] Windows: Use /utf-8 compiler flag

[Steve Dower]

Steve Dower  added the comment:

The new property should go into PCbuild/pyproject.props, but otherwise seems 
like an okay change.

It *will* cause any string literals (const char *) to be UTF-8, but they ought 
to all be ASCII anyway. It shouldn't affect resource files, because those have 
a code page override in the source files. (Potentially a "#pragma 
code_page(1252)" might make more sense for our build, but I'm not sure, and I'm 
just as happy to got to UTF-8 if it doesn't break anything.)

[issue43156] Python windows installer has a confusing name - add setup to its name

[Steve Dower]

Steve Dower  added the comment:

In principle I agree, but need to spend some time thinking about the 
compatibility implications. We've already changed the download page for 3.10, 
so changing the download names as well won't hurt too much - I don't think 
there's a real need for redirects.

If someone wants to prepare a patch, feel free. It'll probably impact 
publishing, so adding the RM for awareness.

[issue43127] Unable to install Python 3.9.1 - Windows 10

[Steve Dower]

Steve Dower  added the comment:

Yeah, system policy is not something we can work around.

If you can, maybe try installing for all users? (Under customised install 
options.) You might have to right click the installer and run as an 
administrator, which sometimes helps get around these policies.

There's almost certainly nothing we can change that would prevent this, so 
we'll eventually close this issue as not a bug. But will leave it open for now 
to see if we can get you going.

[Barry Alan Scott]

Maybe you do an HTTP redirect from the old name to the new name?

[issue42128] Structural Pattern Matching (PEP 634)

[Brandt Bucher]

Brandt Bucher  added the comment:

Also, see my msg379831 above. We can't entirely rely on the PEPs, of course, 
but I think we could still get some decent reuse out of them.

BTW, has the new docs WG started up yet? I keep hearing about it every once in 
a while, but I'm not sure if it's fully-formed yet. Could be good to loop them 
in for review and such, if so.

This is by design. It's not really to do with lists, but to do with  placing

[issue43180] Lists without commas?

[Mike Siegel]

New submission from Mike Siegel :

Perhaps I'm missing something here but this behavior seems unexpected to me. 
"Lists

The items of a list are arbitrary Python objects. Lists are formed by 
placing a *comma-separated* list of expressions in square brackets. (Note that 
there are no special cases needed to form lists of length 0 or 1.)"

>>> import sys
>>> print(sys.version)
3.7.3 (default, Jul 25 2020, 13:03:44)
[GCC 8.3.0]
>>> test = [ "foo" "bar" ]
>>> type(test)

>>> print(test)
['foobar']
>>> import json
>>> json.dumps({ "foo": test })
'{"foo": ["foobar"]}'
>>>

In a complex dict structure this is an easy way to shoot yourself in the foot.

[issue43177] How to use `long double` as a PyObject?

[Ganesh Kathiresan]

Ganesh Kathiresan  added the comment:

Oh I see. Yeah my ask is particularly around support for long double precision 
in python. What I am trying to do is essentially attempt to speed up the 
comparison of NumPy scalars: https://github.com/numpy/numpy/pull/17970. 

We have support for float128 in NumPy, but when I was trying to cast it to a C 
variable, was having a hard time doing so without losing precision.

Please feel free to close the issue, hopefully will see long double support 
sometime in the future.

[issue43112] SOABI on Linux does not distinguish between GNU libc and musl libc

[Natanael Copa]

Natanael Copa  added the comment:

This mentions some examples for musl triplets/tuples:
https://wiki.musl-libc.org/getting-started.html

It points to 
https://github.com/richfelker/musl-cross-make/blob/master/README.md#supported-targets
 which I think is the best documentation. (Rich Felker is the author and lead 
developer or musl libc).

I'm not sure its worth spend time on uClibc which does not seem to have any 
commits at all since 2015. https://git.uclibc.org/uClibc/log/

We will work on our side on buildbot with Alpine linux.

Thank you for being understanding.

[Mark Dickinson]

Mark Dickinson  added the comment:

> Any plans to add it in the future?

It depends - it's not really clear to me what you're asking for.

If you just want to get a Python `float` from a C long double, then cast to 
double in the C code and then use `PyFloat_FromDouble`. Obviously that loses 
any extra precision that the C long double had.

If you're asking for Python to grow a new type of "float" with long double 
precision, that's a *much* bigger ask, and realistically it's not going to 
happen in the forseeable future.

Mark Dickinson  added the comment:

You're correct that there's nothing in the C-API to handle a C `long double`. 
(Similarly, there's very little for C `float` values.)

You've added "ctypes" as a component, but in the message you're talking about 
the C-API. Can you clarify what you're doing? Are you writing C extensions for 
Python, or are you using ctypes?

Hey Ken, I was about to take on this myself, but I wouldn't mind a bit of help.

Your list seems ok, I would add to it a section about PM in the python tutorial 
(which was explicitly mentioned in the SC acceptance notice). 

Regarding the grammar, I believe that one is autogenerated from the parser, so 
it's likely that no changes are required there. Correct me if I'm wrong here.

I'll set up a branch in github and add you as a collaborator so we can prepare 
a PR. I'll base the branch of Brandt's implementation PR. If you give me your 
github id I can add you as collaborator so we can work there.

[issue43112] SOABI on Linux does not distinguish between GNU libc and musl libc

[Christian Heimes]

Christian Heimes  added the comment:

I stand corrected. The last element in the platform triplet does seem to 
indicate libc.

Is there any formal definition of the platform triplet or is it defined by 
GCC's reference implementation? A quick search didn't reveal any decisive 
results.

The next steps here would be:
- document the platform triplet in regards of musl libc (and potentially other 
libcs like uclibc and embedded newlibc)
- buildbot with Alpine musl

Let's continue this on https://discuss.python.org/t/wheels-for-musl-alpine/7084

[issue43179] Remove s390 support

[Christian Heimes]

New submission from Christian Heimes :

configure.ac contains triplet definitions for s390 and s390x mainframes. While 
s390x (Linux on IBM Z) is still widely supported, s390 is not. s390 was 
released in 1990 and discontinued in 1998, 
https://en.wikipedia.org/wiki/IBM_System/390

Ariadne Conill from Alpine pointed out that:

Linux has not supported booting on traditional 31-bit s390 since
Linux 4.1 in 2015. If you can't boot s390 (not s390x) with a modern
kernel, it is absurd to demand that other projects support s390.

https://github.com/pyca/cryptography/issues/5771#issuecomment-775872483

I propose to remove check for __s390__ from configure.ac and configure.

We might also want to remove __alpha__, __hppa__, and __m68k__ at a later 
point. DEC hasn't been around for a long time.

Quoting from Victor Stinner's reply on python-dev 
(https://mail.python.org/archives/list/python-...@python.org/message/X6SZIVOZ233TLLJV43UQEHMV3ELGP34S/):

If there are applications relying on the parameter name, it's better
to trust the Python implementation, rather than the documentation.

It would be better to make these parameters positional only in the
first place, but now it's too late for such backward incompatible
change :-(

[issue43068] test_subprocess: test_specific_shell() fails on AMD64 FreeBSD Shared 3.x

[STINNER Victor]

STINNER Victor  added the comment:

In theory, we should limit external dependencies. In practice, it's too 
convenient to make the assumption that some Unix programs are available and 
work properly.

But PRs are welcome to reduce dependencies to external tools ;-)

[issue43148] Call sys.unraisablehook in the REPL when sys.excepthook is broken

[STINNER Victor]

STINNER Victor  added the comment:

It makes sense to call _PyErr_WriteUnraisableMsg() when sys.excepthook raise a 
new exception. Do you want to propose a PR for that?

sys.excepthook documentation mentions sys.unraisablehook:
https://docs.python.org/dev/library/sys.html#sys.excepthook

threading._make_invoke_excepthook logs threading.excepthook failure using 
sys.excepthook.

Note: Carl also suggested to add a way to invoke sys.unraisablehook explicitly, 
not only for testing purpose. It would help in some cases.

[issue42128] Structural Pattern Matching (PEP 634)

[Ken Jin]

Ken Jin  added the comment:

Guido and Brandt, may I take a stab at the docs for this? I'll probably base 
most of it off PEP 636's tutorial.

Relevant parts of the docs that I've identified:
reference/lexical_analysis.rst
reference/compound_stmts.rst
reference/grammar.rst

# this probably needs a summarized version for non-technical users
whatsnew/3.10.rst

If I missed anything, please point them out :).

[issue36517] typing.NamedTuple does not support mixins

[Ben Avrahami]

Ben Avrahami  added the comment:

The patch PR blocks out a useful idiom: generic Nametuple

>>> class LLNode(NamedTuple, Generic[T]):
... value :T
... next: Optional[LLNode[T]]

I put forward that, at the least, NamedTuple should accept do-nothing bases 
like Generic.

[issue43162] Enum regression: AttributeError when accessing class variables on instances

[Miro Hrončok]

Miro Hrončok  added the comment:

"Wait for the warning to appear in at least two major Python versions. It's 
fine to wait more than two releases."

https://www.python.org/dev/peps/pep-0387/#basic-policy-for-backwards-compatibility

So indeed, if you add the warning in 3.10, the behavior can be removed from 
3.12 earliest.

[issue43178] Redundant method overrides in queue

[Peleg Shilo]

New submission from Peleg Shilo :

PriorityQueue and LIFOQueue override the _qsize method without actually 
changing it. They should just inherit it normally.

[issue43177] How to use `long double` as a PyObject?

[Ganesh Kathiresan]

New submission from Ganesh Kathiresan :

I wanted to know if there is a way to parse and store c `long double`. I only 
found `PyFloat_FromDouble` and in the same page, `PyFloat_GetMax` returns: 
> Return the maximum representable finite float DBL_MAX as C double.

Meaning, there is no scope of `long double`. Can you please tell me how I can 
do something like `PyFloat_FromLongDouble`
