[issue45847] Port module setup to PY_STDLIB_MOD() macro and addext()

[Erlend E. Aasland]

Erlend E. Aasland  added the comment:

Regarding _tkinter (Tcl/Tk):

Based on discussion on Discourse 
(https://discuss.python.org/t/simplifying-tcl-tk-detection/14066), my current 
plan is to just use pkg-config, and drop the rest of the autodetect hackery. 
GH-31698 sort'a works given that pkg-config provides us with correct info. 
Sadly it doesn't for Ubuntu:

```
$ grep lib /usr/lib/x86_64-linux-gnu/pkgconfig/tcl8.6.pc
libdir=/usr/lib/x86_64-linux-gnu
Requires.private: zlib >= 1.2.3
Libs: -L${libdir} -ltcl8.6 -ltclstub8.6
$ ls -ld /usr/lib/x86_64-linux-gnu/{tcl,tk}*
drwxr-xr-x 2 root root 4096 Mar  6 23:59 /usr/lib/x86_64-linux-gnu/tcl8.6
lrwxrwxrwx 1 root root   19 Feb 23  2019 /usr/lib/x86_64-linux-gnu/tclConfig.sh 
-> tcl8.6/tclConfig.sh
lrwxrwxrwx 1 root root   21 Feb 23  2019 
/usr/lib/x86_64-linux-gnu/tclooConfig.sh -> tcl8.6/tclooConfig.sh
drwxr-xr-x 2 root root 4096 Mar  6 23:59 /usr/lib/x86_64-linux-gnu/tk8.6
lrwxrwxrwx 1 root root   17 Feb 23  2019 /usr/lib/x86_64-linux-gnu/tkConfig.sh 
-> tk8.6/tkConfig.sh
```

As you can see, the linker is given the wrong search path, so `AC_LINK_IFELSE` 
fails:

```
$ grep -A4 "gcc.*tcl" config.log
configure:12380: gcc -o conftest  -I/usr/include/tcl8.6  -ltk8.6 -ltkstub8.6 
-ltcl8.6 -ltclstub8.6  conftest.c -lpthread -ldl  >&5
/usr/bin/ld: /tmp/ccMuHSnh.o: in function `main':
conftest.c:(.text+0xb): undefined reference to `Tcl_Init'
/usr/bin/ld: conftest.c:(.text+0x16): undefined reference to `Tk_Init'
collect2: error: ld returned 1 exit status
```

I haven't checked Debian yet, but they may have the same problem.

Plan B:
1. try to push a fix upstream
2. add temporarily hack for Ubuntu/Debian in autoconf
3. remove hack in a year or two

Plan C
1. try to push a fix upstream
2. leave the current hackery as it is and wait another year or two

[issue46942] Convert Object/classobject.c to Argument Clinic

[Oleg Iarygin]

New submission from Oleg Iarygin :

- Convert method.__reduce__, method.__new__, and instancemethod.__new__ to AC. 
It looks like nothing else can be converted in classobject.c.

  This is my first time working with AC so I could make some mistakes.

- Fix found mismatches in method.__new__ where docstring and implementation 
diverged:

  - on how to name arguments (function vs func, instance vs self) - `fuct` is a 
semi-abbreviation and `self` is a special argument of instance methods. No 
compatibility is harmed because these arguments were forced to be 
positional-only anyway with `if (!_PyArg_NoKeywords("method", kw)) return 
NULL;`.

  - on whether args are positional (the implementation called 
_PyArg_NoKeywords) or not (the documentation and 
Lib/idlelib/idle_test/test_calltip.py:80) - align with other assertions in 
`test_builtins()` that have reference docstrings with both `/` marker and a 
proper description.

Minor refactoring:

- Since PyMethod_Type and PyInstanceMethod_Type are modified anyway, transform 
their initialization to C99-style.

- Change a disabler for PyInstanceMethod_Type.tp_hash from comments to `#if 0`.

Hm, looking more closely at Ubuntu (20.4), I see that the pkg-config files is 
actually correct. I'll have to debug this further; perhaps there is an easy way 
out :)

[issue46943] fix[imaplib]: call Exception with string instance

[SpaceOne]

New submission from SpaceOne :

imaplib raises an Exception with a bytes instance once (in login()) - all other 
places str instances are raised.

Adjust the behavior of login() similar to authenticate() where self.error is 
called with a str instance.

Especially for Python3 with strict bytes mode (-bb) this is helpful and 
prevents:

Traceback (most recent call last):
  in ""
self.login(email, password)
  File "/usr/lib/python3.7/imaplib.py", line 598, in login
raise self.error(dat[-1])
imaplib.error: 

During handling of the above exception, another exception occurred:
Traceback (most recent call last):
  in ""
str(exc)
BytesWarning: str() on a bytes instance

[issue46890] venv does not create "python" link in python 3.11

[Ronald Oussoren]

Ronald Oussoren  added the comment:

I have a patch that seems to do the right thing. It required adding 
WITH_NEXT_FRAMEWORK to the globals when evaluating getpath.py to detect this 
scenario.

There probably should be more tests, in particular a test for a virtual 
environment using a framework install as I had to adjust my patch after 
manually testing a virtual environment.

I'm not entirely happy with the patch yet, the change to getpath.py is 
basically the minimal change I could get away with without grokking the entire 
file.

There's no PR yet as I've broken my fork of cpython, fixing that is next up on 
the list.

BTW. Is there a way to find the values that get put into the globals dict for 
getpath.py without using a debugger (either a real one or the printf variant)?

[issue46910] Expect IndentationError, get SyntaxError: 'break' outside loop

[Jonathan Fine]

Jonathan Fine  added the comment:

My main concern is that the door not be closed on improving the user experience 
relating to this behaviour of the compiler.

This issue was raised as a bug for the compiler (which is C-coded). I'd be very 
happy for this issue to be closed as 'not a bug' for the compiler, provided the 
door is left open for Python-coded improvements for the user experience. 

I suggest that the issue title be changed to: The two-pass compile(bad_src, 
...) sometimes does not report first error in bad_src

These two changes to the details of closure would be sufficient to meet my 
concern. I hope they can be accepted.

By the way, I see these improvements being done as a third-party pure-Python 
module outside Python's Standard Library, at least until they've reached a wide 
measure of community acceptance.

You can reach to André Roberge, the author of "friendly" and

[issue46945] Quantifier and Expanded Regex Expression Gives Different Results

[Vivian D]

New submission from Vivian D :

Here are the steps that I went through to test my regular expressions in my 
command prompt (a file attachment shows this as well). I am using Windows 11, 
version 21H2:

>>> import re
>>> regex = r"(((\w)+\w*\3){2}|(\w)+(?=\w*\4)\w*(?!\4)(\w)\w*\5)\w*"
>>> testString = "Alabama and Mississippi are next to each other"
>>> re.findall(regex,testString,re.IGNORECASE)
[('Mississipp', 'ipp', 'p', '', '')]
>>> testString = "alabama and Mississippi are next to each other"
>>> re.findall(regex,testString,re.IGNORECASE)
[('Mississipp', 'ipp', 'p', '', '')]
>>> regex = r"((\w)+\w*\2(\w)+\w*\3|(\w)+(?=\w*\4)\w*(?!\4)(\w)\w*\5)\w*"
>>> re.findall(regex,testString,re.IGNORECASE)
[('alabama', 'a', 'a', '', ''), ('Mississipp', 's', 'p', '', '')]
>>> testString = "Alabama and Mississippi are next to each other"
>>> re.findall(regex,testString,re.IGNORECASE)
[('Alabama', 'A', 'a', '', ''), ('Mississipp', 's', 'p', '', '')]

I created a regular expression to match any words with two sets of the same 
vowel, including words with four of the same vowel, ignoring case. My first 
regular expression “(((\w)+\w*\3){2}|(\w)+(?=\w*\4)\w*(?!\4)(\w)\w*\5)\w*" was 
able to match “Mississippi” but unable to match “Alabama” as it should have. To 
make sure that this error wasn’t somehow caused by a case sensitivity issue, I 
retested the regex with “alabama” instead of “Alabama”, but still I got no 
match on “alabama”. Then I tried replacing the quantifier {2} with just 
expression that was supposed to be repeated. This gave me the regex: 
"((\w)+\w*\2(\w)+\w*\3|(\w)+(?=\w*\4)\w*(?!\4)(\w)\w*\5)\w*". For some reason, 
this was able to match on both “alabama” and “Alabama” now, as shown above, and 
continued to match on Mississippi like expected. However, this result seems to 
contradict my understand of regular expressions because all I did to get these 
different results was copy the expression that was supposed to be executed 
twice by the quantifier.

[issue46890] venv does not create "python" link in python 3.11

[Ronald Oussoren]

I'm now in the fun position where the code works, but the test test_getpath.py

[issue46890] venv does not create "python" link in python 3.11

[Ronald Oussoren]

Ronald Oussoren  added the comment:

I've attached a new patch file with some more tweaks, including the additional 
test case from msg414665.

I've pretty sure that the changes to getpath.py are slightly worse in the new 
version, but aren't fully correct in the initial version as well (see my 
previous message about searching outside of the framework). 

I may return to this later when I have time to try to really understand what's 
going on and compare the logic with the previous C code (especially for 
framework builds).  But for now I'm giving up.

[issue46946] Port core types to Argument Clinic

[Oleg Iarygin]

New submission from Oleg Iarygin :

This is done to:

- update docstrings to current standards enforced by AC
- get proper naming for arguments of impl-functions (for example, self instead 
of obj and instance)
- strip boilerplate reducing current 16k lines of code to something little more 
manageable
- get a proper excuse to collapse overbloated PyTypeObject initializers by 
throwing out zeroes with designated initialization thanks to C99&11 being 
promoted. For example, EncodingMapType in unicodeobject.c reduced from 43 lines 
to 8, five times less.

[issue46948] [CVE-2022-26488] Escalation of privilege via Windows Installer

[Steve Dower]

New submission from Steve Dower :

CVE-2022-26488 is an escalation of privilege vulnerability in the Windows 
installer for the following releases of CPython:

* 3.11.0a6 and earlier
* 3.10.2 and earlier
* 3.9.10 and earlier
* 3.8.12 and earlier
* All end-of-life releases of 3.5, 3.6 and 3.7

The vulnerability exists when installed for all users, and when the "Add Python 
to PATH" option has been selected. A local user without administrative 
permissions can trigger a repair operation that adds incorrect additional paths 
to the system PATH variable, and then use search path hijacking to achieve 
escalation of privilege. Per-user installs (the default) are also affected, but 
cannot be used for escalation of privilege.

Besides updating, this vulnerability may be mitigated by modifying an existing 
install to disable the "Add Python to PATH" or "Add Python to environment 
variables" option. Manually adding the install directory to PATH is not 
affected.

Thanks to the Lockheed Martin Red Team for detecting and reporting the issue to 
the Python Security Response Team.

[issue46949] Print an indication if traceback exceeds sys.tracebacklimit

[Jelle Zijlstra]

New submission from Jelle Zijlstra :

If the number of frames in a traceback exceeds sys.tracebacklimit (which 
defaults to 1000), any remaining frames are silently dropped. See 
https://docs.python.org/3.10/library/sys.html#sys.tracebacklimit.

This is confusing to users. We should print some indication like "N additional 
stack frames not shown".

Here are some specific ideas:
- tracebacklimit <= 0 is documented as dropping the whole traceback. In that 
case, we don't need too print any message.
- It may be expensive to compute a complete count. Perhaps we can count frames 
up to 2 * tracebacklimit, and just say "Many additional stack frames not shown".
- The C implementation is in tb_print_internal() in traceback.c, and the Python 
one in _extract_from_extended_frame_gen in traceback.py.

[issue46949] Print an indication if traceback exceeds sys.tracebacklimit

[Guido van Rossum]

Guido van Rossum  added the comment:

There is general confusion as to which part of the traceback is truncated. If I 
have main() -> f() -> g() -> error(), and the limit is 2, does it print main() 
-> f(), or does it print g() -> error()? (I'm not even sure which would be more 
useful.)

FWIW the reason I suggested printing "many" is a worry that somehow a bug could 
cause counting the length of the list to take forever (e.g. if it ends in a 
cycle). It would seem more robust to limit the count.

I haven't had a chance to go through all your changes, and I'm only very 
vaguely familiar with this space anyway, but isn't WITH_NEXT_FRAMEWORK a 
compile-time option? I'm sure that's how it was used in the old getpath.

> Is there a way to find the values that get put into the globals dict for

warn(str(globals())) or some variant at the top of getpath.py should do it. 
There's also an "#if 0" section in getpath.c that will print it out (unless I 
deleted it before merging). There's nothing permanently built in to do this, as 
I suspect the security concerns (information leakage) would come up more often 
than the debugging concerns.

[issue46949] Print an indication if traceback exceeds sys.tracebacklimit

[Jelle Zijlstra]

Jelle Zijlstra  added the comment:

It skips the least recent frames:

>>> def error(): 1 / 0
... 
>>> def g(): error()
... 
>>> def f(): g()
... 
>>> sys.tracebacklimit = 2
>>> f()
Traceback (most recent call last):
  File "", line 1, in g
  File "", line 1, in error
ZeroDivisionError: division by zero
>>> sys.tracebacklimit = 5
>>> f()
Traceback (most recent call last):
  File "", line 1, in 
  File "", line 1, in f
  File "", line 1, in g
  File "", line 1, in error
ZeroDivisionError: division by zero

(tried on current main)

I think that's the right behavior because it tells you the function that 
actually throws the error, which is much harder to figure out from scratch than 
where the call started.

[issue46744] installers on ARM64 suggest wrong folders

[Steve Dower]

Steve Dower  added the comment:

Good call on the batch file. It should be easy enough to make those options 
case-insensitive, and to support both forms of x86 flag. I'll leave this issue 
open for that if someone wants to have a go, otherwise I'll get to them at some 
point.

[issue46950] Windows 11 venv

[Darrel O'Pry]

New submission from Darrel O'Pry :

I created a virtual env on windows 11. 
When I run pip install -r "..."
I get the error 
```
C:\Users\dopry\src\Client\some.domain.com\django> pip install -r 
.\requirements_to_freeze.txt
Traceback (most recent call last):
  File "C:\Users\dopry\AppData\Local\Programs\Python\Python310\lib\runpy.py", 
line 196, in _run_module_as_main
return _run_code(code, main_globals, None,
  File "C:\Users\dopry\AppData\Local\Programs\Python\Python310\lib\runpy.py", 
line 86, in _run_code
exec(code, run_globals)
  File 
"C:\Users\dopry\src\Client\some.domain.com\django\venv310\Scripts\pip.exe\__main__.py",
 line 4, in 
ModuleNotFoundError: No module named 'pip'
```

When I run get command to verify that the venv is activated I get

```
(venv310) PS C:\Users\dopry\src\Client\some.domain.com\django> Get-Command 
python

---    ---
--
Application python.exe 3.10.21... 
C:\Users\dopry\src\Client\some.domain.com\django\venv310\Scripts\python.exe
```

When I update the `venv310\pyenv.cfg` and set `include-system-site-packages = 
true` to true, it was defaulted to false, it seems that I can pip install my 
requirements successfully. 

When I try to start my app though, the requirements are not found.

[issue46890] venv does not create "python" link in python 3.11

[Ronald Oussoren]

Ronald Oussoren  added the comment:

WITH_NEXT_FRAMEWORK is a compile time option, I've added it to globals in 
values like PREFIX are added. That way the python code can behave differently 
for framework builds (which appears to be needed).

There are two big problems with my patches:
- Calculation of sys.prefix doesn't work in test_venv_framework_macos, but 
somehow works with a real installation. I haven't managed to track down the 
difference yet.
- Calculation for test_framework_macos appears to be ok on first glance, but 
adding "/Library/lib/python9.8.zip" as a known file shows that the code to look 
for the stdlib is misbehaving.

The latter appears to be a wider problem, if I add a test case based on 
test_normal_posix with PREFIX=/opt/python9.8 the getpath code looks for 
/opt/lib/python98.zip and uses that when found.

Test case for this (test passed when 
``ns.add_known_file("/opt/lib/python98.zip")`` is commented out:

def test_normal_posix_in_opt(self):
  """Test a 'standard' install layout on *nix
  
  This uses '/opt/python9.8' as PREFIX
  """
  ns = MockPosixNamespace(
  PREFIX="/opt/python9.8",
  argv0="python",
  ENV_PATH="/usr/bin:/opt/python9.8/bin",
  )
  ns.add_known_xfile("/opt/python9.8/bin/python")
  ns.add_known_file("/opt/python9.8/lib/python9.8/os.py")
  ns.add_known_dir("/opt/python9.8/lib/python9.8/lib-dynload")
  
  # This shouldn't matter:
  ns.add_known_file("/opt/lib/python98.zip")
  
  expected = dict(
  executable="/opt/python9.8/bin/python",
  base_executable="/opt/python9.8/bin/python",
  prefix="/opt/python9.8",
  exec_prefix="/opt/python9.8",
  module_search_paths_set=1,
  module_search_paths=[
  "/opt/python9.8/lib/python98.zip",
  "/opt/python9.8/lib/python9.8",
  "/opt/python9.8/lib/python9.8/lib-dynload",
  ],
  )
  actual = getpath(ns, expected)
  self.assertEqual(expected, actual)

This could be problematic, adding a suitably named file outside of $PREFIX 
breaks the python installation.  I haven't checked this with an unchanged 
getpath.py yet, but I shouldn't have made any changes that affect a 
non-framework install.

[Steve Dower]

Steve Dower  added the comment:

Might be worth changing it then. I double/triple checked whether 
searching up for the zip file was the old behaviour, and it sure seemed 
to be (it wasn't on Windows). Will only be a little tweak to change, 
since both codepaths are already there.

My assumption was that any higher-level directories in that tree would 
be at least as restricted as where Python is installed, so anyone who 
could hijack it there could also have modified it closer to the actual file.

[issue43923] Can't create generic NamedTuple as of py3.9

[Steven Silvester]

Steven Silvester  added the comment:

The use case that prompted https://github.com/python/cpython/pull/31679 is that 
we are adding typings to `PyMongo`.  We are late to using typings,  because we 
only recently dropped Python 2.7 support.  

We have an existing options class that subclasses `NamedTuple`.  We would like 
to make that class `Generic`, but are currently blocked.  

Our current workaround is to create a separate stub file that uses `class 
CodecOptions(Tuple, Generic[T])` and explicitly re-declares the `NamedTuple` 
API.

Switching to `dataclass` would be disruptive, since we still support Python 3.6 
and only rely on the standard library.  We would also require a major version 
update since it would be an API change.
