### Bug description:
As discussed in https://discuss.python.org/t/pep-744-jit-compilation/50756/42 and further with @brandtbucher, I've tried to change the Fedora's Python 3.13 package to utilize `--enable-experimental-jit=yes-off`.
As a starting point, I took the 3.13.0b1-1 package from:
https://src.fedoraproject.org/rpms/python3.13/blob/1c24374362/f/python3.13.spec
And I changed:

That means I added `--enable-experimental-jit=yes-off` to the debug and optimized non-free-threaded builds and some extra build dependencies.
Running the build in Fedora Rawhide (41) chroot resulted in this error during the debug build (which happens first):

`PyEval_GetLocals()` is documented as returning a [borrowed reference](https://docs.python.org/3/c-api/reflection.html#c.PyEval_GetLocals). It now returns a new reference, which causes callers to leak the local variables:

> Based on the discussion in the above linked Discourse topic, I propose to now issue a deprecation warning if sequences are used with named placeholders. The deprecation warning should inform that from Python 3.14 and onward, sqlite3.ProgrammingError will be raised instead.
3.14 dev is now opened, so let's convert the deprecation warning to a programming error sooner than later.

python/cpython | python__cpython-118923 | # Make `frame.f_locals.copy()` return a snapshot dict of `f_locals`
# Feature or enhancement
### Proposal:
Per PEP 667, `frame.f_locals` is now a write-through proxy (`FrameLocalsProxy`) for underlying fast local variables. In the beginning we did not implement the `copy()` method because we think `dict(frame.f_locals)` is a more explicit way to achieve the snapshot. However, there are existing code that's using `frame.f_locals.copy()` to take a snapshot. Moreover, `types.MappingProxyType({}).copy()` returns the copy of the underlying mapping so it's not unprecedented for a `proxy.copy()` to return a dict.
Thus, we should implement `copy()` method for `FrameLocalsProxy` and make it return a dict of snapshot of the current local variables.

----------------------------
Expected that tests will pass as written in doc.
But actually script fails with raising error.
```pytb
raise AttributeError(
AttributeError: 'assret_called_once_with' is not a valid assertion. Use a spec for the mock if 'assret_called_once_with' is meant to be an attribute.. Did you mean: 'assert_called_once_with'?
```
Am i missing something? I have tested this in Python3.11 and Python 3.12.
Looks like documentation must be updated or script must work as said in documenation.

# Bug report
### Bug description:
When editing the last line in a function in the new REPL, hitting Enter doesn't end the block if the last line has indentation on it.
[Demo of the bug](https://asciinema.org/a/658451), [demo of what IPython does](https://asciinema.org/a/658452)
_Originally posted in https://github.com/python/cpython/issues/111201#issuecomment-2101869843_
Here are the noticeable differences in how IPython handles this situation:
1. When hitting the up arrow key to edit the block, the final blank line isn't included (the default cursor position is at the end of the last non-empty line.
2. In IPython I tried purposely adding extra whitespace-only lines (not fully blank but instead containing 4 spaces) by hitting Enter, up arrow, End, Enter, up arrow, End, repeatedly. If I then hit Enter on the first line-followed-by-whitespace-only-lines it ends the block.
3. Hitting up arrow again, will strip whitespace from the end of the block (maybe this is how 1 above is implemented)
Implementing the behavior of 1 (or 3) above might be enough, though 2 seems like it would be even better.

python/cpython | python__cpython-118913 | # The tier 2 optimizer specification contains too much boilerplate
The tier 2 optimizer specification (optimizer_bytecodes.c) contains lots of boilerplate for handling contradictions and running out of space in the optimizer's data structures.
These can be handled but setting flags on the optimizer context and checking those in the abstract interpreter loop.
For example
`OUT_OF_SPACE_IF_NULL(res = sym_new_unknown(ctx));` can be replaced with `res = sym_new_unknown(ctx)`
and
```C
if (!sym_set_type(right, &PyUnicode_Type)) {
goto hit_bottom;
}
```
can be replaced with `sym_set_type(left, &PyUnicode_Type);`
Hopefully this will make the optimizer a bit more approachable and maintainable

python/cpython | python__cpython-119318 | # "Paste mode" in the new REPL does not display the result of evaluated expressions
We've discovered that if you manually type out a condition that evaluates to `False` in the new REPL, `False` is printed as the result, as expected...
```pycon
>>> (3, 13, 0, "final") < (3, 13, 0, "beta")
False
```
...but that if you copy and paste this condition into the REPL, nothing is printed (implying that the condition evaluates to `None`:
```pycon
>>> (3, 13, 0, "final") < (3, 13, 0, "beta")
>>>
```
Thanks @Eclips4 for realising that the difference in behaviour here was due to copying-and-pasting the condition rather than typing it out!

I've been playing a bit with the new REPL, it's so awesome! (thanks to @pablogsal and @ambv for the core.py episode :love_letter: )
I noticed a strange behaviour of the tab completion, whereas upon pressing the tab twice to show available options, the `>>>` prompt jumps down and the options are displayed above it. Please tell me this is a bug and not a feature. :sweat_smile:
### After a single TAB
### After the second TAB
This is on Fedora 39, built with `./configure --with-readline`, in Terminator terminal.
Apologies if I missed something, happy to provide more info.

I was playing with the newest REPL v3.130b1 on my M2 MacBook Pro with macOS 14.3. I built the python binary from the source at commit `b62cb5234b`. It's really impressive and exciting to see how much the standard REPL has evolved in this version.
However the bug occurred while I was playing with the auto-completion on the command. Says I want to see what operations are there under `datetime` module, type `datetime.` and press `Tab` twice, the suggestions show up correctly. But when I try to surf the suggestions with arrow keys pressed several times, I got the `AssertionError`:
```python

```
Not sure if this is the intended behavior of using the new REPL, but I still hope this could be solved as this can largely improve the user experience of using the new auto-completion feature.
Thanks for all your hard works, the new python features are really awesome. Can't wait to see the final release ^^ It's my first issue sending to cpython, and sorry if there is any missing information I did not provide.

The above error occurs when building python 3.13 beta 1 from source on Windows. Have determined that ns.temp not being defined before its is_absolute() method is invoked. Below is the full trace of the AttributeError. Will submit a PR with a patch that is working for me.

python/cpython | python__cpython-118854 | # Default expr_context parameters in ast to Load()
# Feature or enhancement
### Proposal:
In #105858, we changed the AST node constructors to raise a DeprecationWarning when any required fields are omitted. Optional fields default to None and list fields default to an empty list. In real-world usage, it emerges that it's often also useful to omit the `ctx` argument to various classes (Attribute, Subscript, Starred, Name, List, Tuple); its value often does not matter, and it's convenient to have it default to `ast.Load()`.
I'd like to backport this to 3.13 since it helps undo a noisy DeprecationWarning.

### Bug description:
When we build Python 3.13.0b1 in Fedora with `--disable-gil --enable-optimizations`, the PGO task fails. I was able to reproduce this from the 3.13 branch by:
```
$ ./configure --config-cache --without-ensurepip --disable-gil --enable-optimizations
$ make
...
# Next, run the profile task to generate the profile information.
./python -m test --pgo --timeout=

I don't know what the failure is, as using `-v` is not possible:
```
$ ./python -m test --pgo -v
usage: python -m test [options] [test_name1 [test_name2 ...]]
python path/to/Lib/test/regrtest.py [options] [test_name1 [test_name2 ...]]

```
I can however run the pgo tests manually like this:

I don't recall which alpha I've tested it last on, but I'm pretty sure it used to work (against LLVM 16). I'm getting the same result on main as of 7c87ce777b3fd9055b118a58ec8614901ecb45e9.
This is Gentoo Linux amd64.
I've reproduced by doing (in git repo):
```
export PATH=/usr/lib/llvm/18/bin:${PATH}
./configure --enable-experimental-jit
make
```

IndexError: list index out of range
```
and it exits with status code 1.
My terminal is currently 126 columns by 45 lines, and I have a custom PYTHONSTARTUP environment file pointing to ~/.python, which [you can see in this GH repo](https://github.com/mgedmin/dotfiles/blob/6d4a537e85e58712dc436cae00edddc22673ee71/python). It sets up some conveniences for the old REPL (colorful prompt, rlcompleter-based tab-completion, persistent readline history).
Running `PYTHONSTARTUP= python3.13` fixes the IndexError.
By commenting out bits of the file I can reproduce the IndexError with just this:
```python
import sys
sys.ps1 = '\001\033[0;32m\002>>> \001\033[0m\002'
del sys
```
The `\001`/`\002` characters are hints for readline to inform it that everything between them is a terminal escape sequence that doesn't advance the cursor, without which readline cannot correctly compute the width of the prompt and makes wrong assumptions about line wrapping.
The IndexError goes away if I remove all `\001` and `\002` characters from sys.ps1.

python/cpython | python__cpython-118848 | # Zero-valued flag enum has no name
# Documentation
Quoting `Doc/howto/enum.rst:1148`:
```rst
- names of pseudo-flags are constructed from their members' names::
>>> (Color.RED | Color.GREEN).name
'RED|GREEN'
```
This section was originally added in 7aaeb2a3.
If you have a zero-valued flag, and you didn't explicitly give it a name, this doesn't seem to apply, it returns `None` instead.
```py
class NoZero(Flag):
ONE = 1
class HasZero(Flag):
ZERO = 0
ONE = 1
print(NoZero(0).name, type(NoZero(0).name)) # None <class 'NoneType'>
print(HasZero(0).name, type(HasZero(0).name)) # ZERO <class 'str'>
```
I'm not entirely sure if this should be considered a documentation issue or a bug report (or both). It doesn't really feel like zero should be treated any differently from other unnamed combinations. But at the same time, I've tested, and this is already the existing behavior in 3.10 through 3.12, and it doesn't seem to be documented anywhere.

python/cpython | python__cpython-118797 | # `_PyWeakref_ClearRef` and `_PyWeakref_ClearWeakRefsExceptCallbacks` should be exposed in 3.13
`_PyWeakref_ClearRef` was previously [exposed](https://github.com/python/cpython/blob/656491783d2be0fe36feef5085a2406a05abbd66/Include/cpython/weakrefobject.h#L37) in the public C-API. In 3.13, it was moved to `pycore_weakref.h` and the symbol is not exposed (i.e., it's `extern void` instead of `PyAPI_FUNC(void)`.
`_PyWeakref_ClearRef` is used to clear a single weakref without calling its callback. `_PyWeakref_ClearWeakRefsExceptCallbacks` is the thread-safe version. If people are using `_PyWeakref_ClearRef`, we'd rather they use `_PyWeakref_ClearWeakRefsExceptCallbacks` so that the code is thread-safe in the free-threading build.
One use case is to clear newly added weakrefs after you've called a finalizer, in case your C type does not delegate to subtype_dealloc.
Uses:
* [PyTorch](https://github.com/pytorch/pytorch/blob/f4b2d50fd738d2ff2a8dde2f218411052f1c2716/torch/csrc/autograd/python_variable.cpp#L1927-L1931)
* [shiboken2](https://github.com/pyside/pyside2-setup/blob/d526f801ced4687d5413907a93dedcd782ef72fa/sources/shiboken2/libshiboken/typespec.cpp#L297) (might be old)
* [Nuitka](https://github.com/Nuitka/Nuitka/blob/f8046cdcf8c14b4a274005799349b56d812acb17/nuitka/build/static_src/HelpersAllocator.c#L384)
At a minimum, we should add `PyAPI_FUNC` to `_PyWeakref_ClearRef` and `_PyWeakref_ClearWeakRefsExceptCallbacks` and consider making `_PyWeakref_ClearWeakRefsExceptCallbacks` part of the public C API.

This can reasonably happen if you have a generic class generic over a TypeVar with a default, and that TypeVar appears in a Callable parameter type annotation:
```
class X[T1=int]:
def meth[T](self, x: Callable[[T1], T]): pass
```
We encountered this in Hypothesis.

python/cpython | python__cpython-118782 | # Tkinter getint(), getboolean() argument must be str, not tuple
# Bug report
Discovered during 3.13b1 release (we decided not to block the release over it, so this is just a known issue in b1):
While interacting with the config dialog in IDLE, I get these errors printed in the background.
```pytb
Exception in Tkinter callback
Traceback (most recent call last):
File "D:\cpython\Lib\tkinter\__init__.py", line 2064, in __call__

~~~~~~~~~~~~^^^
File "D:\cpython\Lib\tkinter\__init__.py", line 1726, in getint_event
return getint(s)

```
I suspect this is the underlying cause of these test failures, which were discovered in our final stage testing of the Windows release:

python/cpython | python__cpython-118751 | # Asymptotically faster `int(string)`
### Proposal:
EDIT: I made better progress on this than I expected, reducing the cutoff dramatically to about 3.4 million digits, by revisiting and improving the "cached reciprocal approximation" approach. Still not really compelling, but ... what the heck :wink:.
Way back when we were first working on ideas for faster `int <-> decimal string` conversions, @pochmann worked up a function that used the `decimal` module to, in effect, convert from base 10 to base 256. This is "unnatural", in that it requires multiplying and dividing by large powers of 2, which `decimal` isn't naturally suited to. But `decimal`'s `*` and `/` are asymptotically superior to CPython's, so at _some_ point it could be expected to win.
Alas, the crossover point was too high to be of much real interest. I then worked on ways to replace its division with multiplication by a cached reciprocal approximation instead, fixing up (usually small) errors afterwards. This reduced the crossover point significantly, but still too high to be of much real interest. And the code grew increasingly complex.
While working on `_pylong.py` across the last few days on a different issue, I had a different idea: there's no actual need to divide by powers of 2 at all. Since `2*5 = 10`, division by `2**k` is the same as multiplying by `5**k` (exact) and then dividing by `10**k` (also exact in `decimal`, and dirt cheap: the module's `scaleb()` function, which just adjusts the internal exponent).
This yields short and reasonably clear code with a much lower crossover value, at about 26 million digits. That's still too high to be compelling, but I want to record the progress in case someone else is intrigued enough to pursue it (I'm out of time for this for now). So I intend to add the (working, but unused) code to `_pylong.py`.

I noticed this with my one of my PRs, gh-118157, which makes some changes related to importing extension modules. However, I don't know if that PR is at fault. I definitely don't have much insight into what might be causing the hangs.

python/cpython | python__cpython-118725 | # Change in `pdb` behavior at exit from post-mortem debugger
# Bug report
### Bug description:
In 3.12 and earlier, if user enters `quit`/`exit` commands or does Ctrl-D, `pdb` restarts script with corresponding message and exits only on repeated `quit`/`exit`/Ctrl-D:
```
$ python -m pdb -c c pdb_bug.py
Traceback (most recent call last):

$
```
Since fa18b0afe47615dbda15407a102b84e40cadf6a5 only message is printed, but Python exits completely:
```
$ ./python -m pdb -c c pdb_bug.py
Traceback (most recent call last):

Post mortem debugger finished. The /home/radislav/projects/cpython/pdb_bug.py will be restarted
$
```
@gaogaotiantian, what's your opinion? Should we restore the old behavior or remove confusing message about "restart"? As I can see, `pdb` docs doesn't state explicitly what `quit`/`exit` commands should do in post-mortem debugger.

python/cpython | python__cpython-120698 | # Make `IPv{4,6}Address.version` and `max_prefixlen` available on classes, not just instances
# Feature or enhancement
### Proposal:
Sometimes, when there is a function that can operate both on IPv4 and IPv6 addresses, it is convenient to pass it the corresponding type object (either `IPv4Address` or `IPv6Address`) as an argument. However, that function cannot access the properties `version` and `max_prefixlen` using those type objects, because they only work on instances. This can be worked around by constructing a dummy instance (e.g. `t(0).max_prefixlen`), but it would be more convenient if those properties could be used on the type object directly (i.e. `t.max_prefixlen`), because their value doesn't depend on the specific instance, only on the type.
The proposal is to make `IPv4Address.version`, `IPv4Address.max_prefixlen`, `IPv6Address.version`, and `IPv6Address.max_prefixlen` evaluate to 4, 32, 6, and 128, respectively. Currently, all those expressions evaluate to property descriptors.

python/cpython | python__cpython-119216 | # Avoid creating a StopIteration instance for monitoring
# Feature or enhancement
### Proposal:
A new C-API for injecting monitoring events was discussed in https://github.com/python/cpython/issues/111997 and implemented for Py3.13 in https://github.com/python/cpython/pull/116413
A remaining issue is that signalling "STOP_ITERATION" events requires a `StopIteration` exception instance, whereas generators usually try to avoid creating one during termination to increase their performance.
I think it would be best if CPython's monitoring infrastructure created a StopIteration instance automatically when it detects that it needs to notify about it without having one. It's in the best position to detect whether it really needs an exception instance or not. Event sources shouldn't be forced to a) figure that out themselves or b) create an instance just for it to be thrown away.
CPython already creates an exception instance for submitting a monitoring event for a generator, but does so unconditionally. It would also benefit from not having to generate one unless it's really needed for signalling.
https://github.com/python/cpython/blob/52485967813acdb35c274e1b2eaedd34e9ac01fc/Python/bytecodes.c#L289-L317
Basically, we should move the existing code from the byte code handlers all the way to the other side into the notification mechanism.
In order to report the correct StopIteration value, the event creation function should accept an object value directly, and create a `StopIteration` instance for that value only if it ends up signalling it to listeners.
We might allow passing the value `NULL` (as opposed to the object value `None`) to make the machinery look up an actually existing currently raised `StopIteration` instance. Alternatively, passing a `StopIteration` instance as value is probably also a reasonably clear indication for an instance being available already. We may also consider adding two event creation functions, one with a bare stop value and one with a readily created `StopIteration` instance.
This ticket proposes a usability/performance enhancement to a newly added feature in Py3.13, and thus does not fall under the "beta-1" release end of new features.

python/cpython | python__cpython-118681 | # Add additional optional type parameter to `typing.ContextManager` and `typing.AbstractContextManager`
# Feature or enhancement
### Proposal:
As part of https://github.com/python/typeshed/pull/11048 `contextlib.AbstractContextManager` and `contextlib.AbstractAsyncContextManager` received an additional optional type parameter for the return value of `__exit__` in order to have greater control over code-flow analysis in type checkers with things like `ExitStack`.
The `contextlib` `ABC`s don't require any changes, since they accept an arbitrary number of arguments at runtime, but the aliases that live in `typing` are a different story. These will reject the additional parameter at runtime, throwing an exception.
@JelleZijlstra Added support for type var defaults for `typing._SpecialGenericAlias` in #118648, we could leverage that work to add the new optional parameter to the typing aliases, so they can support the same number of type parameters as their `contextlib` counterparts.

python/cpython | python__cpython-118669 | # Inconsistent return types between SSLSocket and SSLObject certificate chain APIs
# Bug report
### Bug description:
The `get_verified_chain()` and `get_unverified_chain()` APIs for `SSLSocket` were updated in https://github.com/python/cpython/pull/109113, but the API wasn't updated for `SSLObject`. This leads to inconsistent return types, one returns `_ssl.Certificate` and the other returns `bytes`. It appears from https://github.com/python/cpython/pull/109113 that `bytes` is what's expected.
This [caused an issue for Windows and macOS](https://github.com/pypa/pip/pull/12662#issuecomment-2093887075) using Truststore which relies on these APIs for verifying certificates. A bugfix is coming for Truststore, but these APIs should return the same type.

python/cpython | python__cpython-118651 | # Enum _sunder_ exclusion is overly strict
# Bug report
### Bug description:
Enums' exclusive access to \_sunder_ members inhibits their use with the IPython/Jupyter pattern of making HTML and other visual reprs available:
```python
from enum import Enum
class MyEnum(Enum):
A = 1
def _repr_html_(self):
return f'<span title="A MyEnum">{self}</abbr>'
# ValueError: _sunder_ names, such as '_repr_html_', are reserved for future Enum use
```
While having exclusive access to some space is valuable, and prefixing enum's range is not practical (as that prefix would need to be repeated by users constructing the class), carving out some space for widespread functions that are not expected to conflict with Enum's internal use should be possible. I suggest that at least `_repr_html_` should be allowed, possibly the whole `_repr_` prefix.

### Bug description:
The following code breaks with an attribute error:
```python
import email.parser
import email.policy
a = 't'*46
h = f'''\
To: =?utf-8?B?dGVzdC50ZXN0LnRlc3QudGVzdEB0ZXN0LmNvbeKAiw=?= <test@test.com>,\r\n\t"tttest&{a}.t.t.t.t.t.t.t@yahoo.ES" <test@test.tj>,\r\n\t"tttest&{a}.t.t.t.t.t.t@yahoo.ES" <info@test.tj>'''
m = email.parser.HeaderParser(policy=email.policy.default).parsestr(h)
m.as_string()
```
The problem was introduced on https://github.com/python/cpython/pull/100885, setting `ListSeparator.as_ew_allowed = False` to `True` fixes the problem. Changing any character in the header in the example above also fixes the problem (which makes it harder to understand exactly why it's broken).

Whenever I start the REPL on Windows, it now prints a new statement: "warning: can't use pyrepl: No module named 'readline'" and as things now, it will continue to do so indefinitely. This is obnoxious. This is not a warning, not something I can or should do anything about (other than switch to Linux), but a statement of fact. Please kill it at least on Windows. And Mac if the situation is the same (never available). It seems useless on *nix too, though I don't care. Just document its availability in appropriate places like we do with other things that are not available everythere.
If desired to make its use obvious, color the splash message in places.

python/cpython | python__cpython-118611 | # Centralize power caching in `_pylong.py`
### Proposal:
A number of functions in `_pylong.py` craft their own schemes to cache costly `**` results. This complicates their code, and all of them end up doing more work than necessary.
So I want to add a new internal `compute_powers()` function that computes all and only the powers needed in advance, and returns a dict recording the results. It should speed things, but not by much (the time is dominated by how long it takes to compute the single largest power needed). The real point is code simplification.

Objects/frameobject.c:390:59: warning: omitting the parameter name in a function definition is a C2x extension [-Wc2x-extensions]
framelocalsproxy_values(PyObject *self, PyObject *__unused)
^
```
I think it's ok to address all of these issues in one PR.

python/cpython | python__cpython-118597 | # Add thread-safety clarifications to the SSLContext documentation
# Documentation
Currently there is no documentation that tells anything about whether `SSLContext` is thread-safe or not and how it can be shared between different connections. Knowing how to share the `SSLContext` between different threads and connections is important for example to solve problems like [this](https://github.com/python/cpython/issues/95031).
This issue has also come up [here](https://github.com/psf/requests/pull/6667) where the matter was clarified by @tiran in [this comment](https://github.com/psf/requests/pull/6667):
> `SSLContext` is designed to be shared and used for multiple connections. It is thread safe as long as you don't reconfigure it once it is used by a connection. Adding new certs to the internal trust store is fine, but changing ciphers, verification settings, or mTLS certs can lead to surprising behavior. The problem is unrelated to threads and can even occur in a single-threaded program.
I have reworked this statement into a PR so that it's generally available for future reference.

python/cpython | python__cpython-119936 | # inspect.signature.BoundArguments "POSITIONAL_OR_KEYWORD" Arguments are always args
# Feature Request
### Feature description:
```python
from inspect import signature
def foo(bar, /, baz, *, bat):
...
ba = signature(foo).bind('bla', baz='bli', bat='blub')
```
In this case the argument `baz` get returned with `ba.args`, which returns `('bla', 'bli')`
I expected it in `ba.kwargs`, but that returns only `{bat: 'blub'}`.
Binding `baz` positional (`bind('bla', 'bli', bat='blub')`) works as expected.
Here `ba.args` returns `('bla', 'bli')` again and `ba.kwargs` `{bat: 'blub'}`.
Is this behavior wanted like this?
In my perspective it makes more sense when the `BoundArguments` class returns `POSITIONAL_OR_KEYWORD` arguments as it got it (positional as `args` and keyword as `kwargs`) and not always as `args`. I think there happens a lost of Information .
Edit:
At least it not cause errors, because in constellations, where it is necessary to be a keyword it is. So it also could argued against the information lost, that it is a build in feature of simplification of unnecessary keywords.
See the following example:
```python
from inspect import signature
def foo(bar, /, new='blub', baz='bla', *, bat='bli'):
...
ba = signature(foo).bind('bla', baz='bli', bat='blub')
```
`ba.args` => `('bla',)`
`ba.kwargs` => `{'baz': 'bli', 'bat': 'blub'}`

python/cpython | python__cpython-118570 | # How to dynamically create PEP695 classes? Let's add a test for it
# Feature or enhancement
Right now we don't have a single test to dynamically create a PEP-695 class.
It is quite complex, because, for example, it cannot be done via `type()`, you have to use `types.new_class`. Example:
```python
import typing
T = typing.TypeVar('T', infer_variance=True)
Klass = type(
'Klass',
(typing.Generic[T],),
{'__type_params__': (T,)},
)
```
Produces:
```python
Traceback (most recent call last):
File "/Users/sobolev/Desktop/cpython2/ex.py", line 9, in <module>
Klass = type(
'Klass',
...<2 lines>...
# set_type_params,
)
TypeError: type() doesn't support MRO entry resolution; use types.new_class()
```
This is fine (I guess?)
Since `types.new_class` is mentioned and it is there to create classes with complex MROs, we need to be sure that it works the same way as regular `class My[T]: ...`
I will send a PR.

# Bug report
### Bug description:
In `drop_gil()` in ceval_gil.c, there's a check to see if `gil->locked`, but it's loaded using `_Py_atomic_load_ptr_relaxed` instead of `_Py_atomic_load_int_relaxed`. This sort of "works" because:
- `_Py_atomic_load_ptr_relaxed` takes `const void*` rather than something more specific like `const void**`, so the fact that `&git->locked` is an `int*` causes no compiler displeasure.
- It's just an assertion, so the fact that on 64-bit platforms, this loads the adjacent `switch_number` field just means that the assertion won't fire in some cases where it should.
I don't think this is any kind of security issue and it's probably benign, but worth fixing for sanity.

python/cpython | python__cpython-118528 | # Scaling bottlenecks in the free-threaded build
There are a few remaining scaling bottlenecks in the free-threaded build that we should fix.
I have been using the following benchmark to detect bottlenecks that were previously issues in older versions of the nogil forks:
https://gist.github.com/colesbury/429fe9f90036d43ad43576c3d357a12e
Note that for reliable results the above benchmark requires some setup:
* Adjust `NTHREADS` if necessary on your system
* Disable [turbo boost](https://askubuntu.com/a/1163808) or equivalent on your system
* Avoid running on hyper-threading siblings (i.e., use `taskset -c 0-<N>` to choose separate physical cores)
### Current bottlenecks
* cmodule_function
* load_string_const
* load_tuple_const
* create_closure
### Underlying issues
* Reference count contention on non-string constants. We will want to immortalize most constants in `PyCodeObject`.
* Reference count contention on `func.__qualname__` or `code.co_qualname` (when creating closure)
* Reference count contention on module-level `PyCFunctionObjects`

python/cpython | python__cpython-119155 | # re docs should state exactly which whitespace is matched by \s
# Documentation
Currently, and since 3.0 it seems, it simply states that `\s` "Matches Unicode whitespace characters (which includes `[ \t\n\r\f\v]`, and also many other characters, for example the non-breaking spaces mandated by typography rules in many languages)."
But "Unicode whitespace characters" seems awfully vague. Exactly which [General_Category value] does that correspond to? Space_Separator (Zs)? Separator (Z)? Some Python-specific selection of ""Unicode whitespace characters""? It's not entirely clear.
The 2.7 docs were better, stating that "If [`UNICODE`](https://docs.python.org/2.7/library/re.html#re.UNICODE) is set, this will match the characters `[ \t\n\r\f\v]` plus whatever is classified as space in the Unicode character properties database."
I'd like to believe that Python 3.x uses the exact same definition for `\s` as 2.7 did, and that therefore I already have the answer to my question. I'd like to believe a lot of things. But computers don't run on belief(s).
No one should have to resort to digging thru the source code for the answer to such a simple but important question.
P.S. I did try searching the interwebs for an answer to "which whitespace is matched by \s in python". Unfortunately search engines seem entirely unwilling to help. Perhaps no one else knows or wants to know. That's a shame.

zipapp is a format Python officially supports and it seems like pdb should just support debugging it. I don't see a reason why we would not want to do that. Also as all the pieces are already in there, it's not difficult to support it.

python/cpython | python__cpython-118474 | # sys.set_asyncgen_hooks with invalid firstiter may partially set finalizer
# Bug report
### Bug description:
```python
finalizer = lambda *a: None
try:
sys.set_asyncgen_hooks(firstiter="invalid", finalizer=finalizer)
except TypeError: # TypeError due to invalid `firstiter` type
cur = sys.get_asyncgen_hooks()
self.assertIsNone(cur.firstiter) # This is not set
self.assertIsNone(cur.finalizer) # But this is set
```
[PEP 525](https://peps.python.org/pep-0525/) doesn't imply or define partial initialization priority. Since inside of `set_asyncgen_hooks` is blackbox to user, this is surprising and users are hard to know they have to back up current setup and recover it when `TypeError` happens.
Inconsistency also cause user experience problem. Current order `sys.set_asyncgen_hooks(firstiter="invalid", finalizer=finalizer)` causes partial set, but `sys.set_asyncgen_hooks(firstiter=finalizer, finalizer="invalid")` will not.

python/cpython | python__cpython-118456 | # mangle_from_ default in email.policy.Policy.__doc__ is wrong
# Bug report
### Bug description:
```
>>> from email.policy import Policy
>>> Policy.mangle_from_
False
>>> print(Policy.__doc__)
...
mangle_from_ -- a flag that, when True escapes From_ lines in the
body of the message by putting a `>' in front of
them. This is used when the message is being
serialized by a generator. Default: True.
...
```
This attribute was added in https://github.com/python/cpython/commit/fdb23c2fe5499d26701fa34873c1cdc347adcb80 and was always False by default, as far as I can see.
The [docs](https://docs.python.org/3/library/email.policy.html#email.policy.Policy.mangle_from_) also correctly say that it defaults to False. I don't know why the class docstring says otherwise.

# Bug report
### Bug description:
GNU coreutils `realpath -m` doesn't raise an error for secret symlinks (no read permission):
```zsh
wannes@Stefans-iMac dirs % sudo ls -l secret-symlink
l--------- 1 wannes staff 44 Jun 30 2023 secret-symlink -> /Users/wannes/path-picker/link-test/dirs/dir
wannes@Stefans-iMac dirs % grealpath -m secret-symlink

But `posixpath.realpath()` does:
```python
>>> import posixpath

Traceback (most recent call last):

python/cpython | python__cpython-125467 | # Add `INSTRUCTION_SIZE` macro to code generator.
In bytecodes.c we use both `next_instr - this_instr` and `1 + INLINE_CACHE_ENTRIES_...` to mean "instruction length".
We should add a macro for the purpose that is understood by the code generator.
### Examples
The somewhat confusing `LOAD_IP(1 + INLINE_CACHE_ENTRIES_SEND);` would become `LOAD_IP(INSTRUCTION_LENGTH)`
`frame->return_offset = (uint16_t)(next_instr - this_instr);` would become `frame->return_offset = INSTRUCTION_LENGTH;` which is both easier to understand and wouldn't be rejected as tier 2 code.

python/cpython | python__cpython-118428 | # Implement inspect.signature() for sqlite3 connection object
# Feature or enhancement
`sqlite3.connection()` returns a custom callable object. But `inspect.signature()` returns a generic `<Signature (*args, **kwargs)>` for it:
```pycon
>>> import inspect, sqlite3
>>> con = sqlite3.connect(':memory:')
>>> con('select 1')
<sqlite3.Statement object at 0x7f76842d2fd0>
>>> inspect.signature(con)
<Signature (*args, **kwargs)>
```
This issue is similar to #118285 and #118402.

`functools.cmp_to_key()` returns a custom callable. `inspect.signature()` ~returns generic `<Signature (*args, **kwargs)>`~ raises a TypeError for the C implementation. The following PR makes it returning the same signature (`<Signature (obj)>`) for both Python and C implementations (currently it is returned for the Python implementation).
This issue is similar to #118285.

The `'Doc/sphinx-warnings.txt'` file is a generated file so maybe we upgraded sphinx at some point and the new version does not generate the file if there's no warnings?

### Proposal:
This is an inefficient way to build a tuple:
```c
Py_BuildValue("(OO)", a, b)
```
This is faster, and more readable:
```c
PyTuple_Pack(2, a, b)
```
And if #118222 lands, we could use this even faster variant for length 1 & 2:
```c
PyTuple_Pack2( a, b)
```

python/cpython | python__cpython-118454 | # Simple racing class attribute read-write crashes on free-threaded builds
# Crash report
### What happened?
The following segfaults:
```python
from multiprocessing.dummy import Pool
NTHREADS = 6
class A:
attr = 1
BOTTOM = 0
TOP = 1000
ITERS = 100
def read(id0):
for _ in range(ITERS):
for _ in range(BOTTOM, TOP):
A.attr
# print(A.attr)
def write(id0):
for _ in range(ITERS):
for _ in range(BOTTOM, TOP):
# Make _PyType_Lookup cache hot first
A.attr
A.attr
x = A.attr
x += 1
A.attr = x
# print(f"WRITTEN {x}\n")
def main():
with Pool(NTHREADS) as pool:
pool.apply_async(read, (1,))
pool.apply_async(write, (1,))
pool.close()
pool.join()
main()
print("done")
```
The first issue is that we have `assert(_PyType_HasFeature(type, Py_TPFLAGS_VALID_VERSION_TAG));` in `typeobject.c`, which may not be true as another thread can modify the attribute in the meantime. We should remove that assertion.
The next issue, which I have not yet been able to solve, is that the attribute evaporates midway in `_Py_type_getattro_impl`. This is likely caused by a decref of another thread. So far I've tried changing `_PyType_Lookup` and `find_name_in_mro` to return strong references, but they don't seem to solve it for some reason.

python/cpython | python__cpython-118368 | # Broken `bdb.Bdb.user_call` API
# Bug report
### Bug description:
This is an issue with how `bdb.Bdb.user_call` is documented.
According to the [`bdb` documentation](https://docs.python.org/3/library/bdb.html#bdb.Bdb.user_call), `bdb.BdB.user_call` has two arguments, `frame` and `argument_list`.
This is implemented in the `bdb` library [here](https://github.com/python/cpython/blob/3.12/Lib/bdb.py#L118).
However, according to the [`sys` documentation](https://docs.python.org/3/library/sys.html#sys.settrace), `sys.settrace` will always set the `arg` to `None` and the code above acknowledges that _"# XXX 'arg' is no longer used"_.
I don't know if this is based on a previous version that would give the call arguments, but I think we should change the signature of `bdb.Bdb.user_call` to exclude the `argument_list` parameter or state in the documentation that it will be `None`.

python/cpython | python__cpython-118386 | # Python 3.12.3 installer fails to install py.exe
# Bug report
### Bug description:
I use Python with MkDocs and had needed to update my environment on a Windows 10 machine that only had Python 3.7. I installed version 3.12.3 since it is the latest stable at the time. I used all the default settings. Afterwards, I ran `py --version` and `py --list` and it does not show the latest installation. I thought I must have missed something so I uninstalled 3.12.3 and reinstalled, being careful that the box to install `py.exe` is checked. The installer does not ask for admin permissions. I can run 3.12.3 in its shell via the ***Start*** menu, but it is not known to `py.exe` and the `C:\Winddows\py.exe` executable file has a really old date. I then installed Python 3.9.2 because that is consistent with a Linux environment that I use on another machine. Installing with the default settings, the installer askes for admin permissions and `py.exe` shows the `3.9-64` version and has a newer date consistent with the installer. **It seems to me that the 3.12.3 installer is not handling the `py.exe` installation correctly.** I see some other issues related to the installer but not this specific issue, as far as I can tell.

python/cpython | python__cpython-118339 | # Configure Tier 2 interpreter at build time
It would be nice if by default we didn't ship the optimizer infrastructure, since approximately nobody is going to use it, so we should ship (and by default build) binaries that just don't include it.
I propose to enable it only when configured with `--enable-experimental-jit-interpreter`. We drop support for `PYTHON_UOPS` and `-Xuops`, in favor of `PYTHON_JIT=0|1`.
@mdboom this will have some consequences for the benchmarking infra; checking the `Tier 2` box should use this configure option rather than setting the `PYTHON_UOPS=1` env var. It should be possible to use both (`./configure` gives a warning but otherwise seems to ignore incorrect flags, and the env var will just be ignored).

### Explanation
There are two subtle things leading to the deadlock:
1) Thread 2 is waiting for other threads to stop themselves using a [`PyEvent_WaitTimed`](https://github.com/python/cpython/blob/5a90de0d4cbc151a6deea36a27eb81b192410e56/Python/pystate.c#L2230) call, which temporarily detaches and then re-attaches the thread state. In the process of re-attaching, the PyThreadState resumes the top most critical section, which in this case is trying to re-acquire the warnings mutex. (That's a bit weird!)
2) Thread 5 holds the warning mutex. Normally, threads suspend their critical sections detaching but in this case the lock was handed off directly from some other thread to thread 5 [^1]. Thread 5 didn't process that yet, so it doesn't "know" that it holds the mutex.
### Possible fixes:
1) Don't detach when calling `PyEvent_WaitTimed()` in the stop-the-world. Basically, add a variant of `PyEvent_WaitTimed` that accepts `_Py_LOCK_DONT_DETACH` so we never suspend/resume the critical section in the thread performing the stop the world.
2) Insert a dummy critical section in `stop_the_world` (and remove it in `start_the_world`). The thread can still detach, but when it re-attaches it doesn't try to resume any critical sections (until it's done performing the stop-the-world).
3) Avoid handing off locks directly. I'm pretty sure we want to keep supporting handoff, but I listed it here because I think it would also avoid the deadlock.
Both (1) and (2) seem reasonable to me. I'm not sure which is better.
[^1]: `PyMutex` implements stochastic fairness. Basically, after waiting for a while, locks are handed off directly to the next waiter in line without unlocking the mutex so that eventually everyone gets a turn.

# Bug report
### Bug description:
One of my PRs (https://github.com/python/cpython/pull/118283) started failing (https://github.com/python/cpython/actions/runs/8843882336?pr=118283) with this. Investigating, I can reproduce it locally on `main`, although I don't know why the CI passes on `main`.
OS: macOS Sonoma 14.4.1, M2.
## To reproduce
```sh
git clone https://github.com/python/cpython
cd cpython
./configure --with-pydebug && make -j10
./python.exe Lib/test/test_repl.py
```
## Actual result
```pytb
.....F.

gh-111926: Make weakrefs thread-safe in free-threaded builds (#117168)
Most mutable data is protected by a striped lock that is keyed on the
referenced object's address. The weakref's hash is protected using the
weakref's per-object lock.
Note that this only affects free-threaded builds. Apart from some minor
refactoring, the added code is all either gated by `ifdef`s or is a no-op
(e.g. `Py_BEGIN_CRITICAL_SECTION`).

PR: https://github.com/python/cpython/pull/117168
Issue: https://github.com/python/cpython/pull/111926
The PR was merged three weeks ago and the CI is passing.
---
On my PR (https://github.com/python/cpython/actions/runs/8843882336?pr=118283), free-threaded builds pass, but regular ones fail. Ubuntu and macOS fail with:
```pytb
AssertionError: -6 not found in (1, 120)
```
Windows with:
```pytb
AssertionError: 3221225477 not found in (1, 120)
```
3221225477 seems to be 0xc0000005 `STATUS_ACCESS_VIOLATION`.

[Doc/library/binascii.rst](https://docs.python.org/3/library/binascii.html#module-binascii) defines that a valid base64 "Contains no excess data after padding (including excess padding, newlines, etc.)". However, current implement does not handle the edge case of excess padding after no padding.
