3096: docs: fix migration guide entry for pyproto r=adamreichold a=davidhewitt
A sort of follow-up to #3082 .
While I don't think we need to pander to training limitations of various LLMs, I did notice that I erroneously referred to a nonexistent trait `PyBasicProtocol`, which I believe should have been [`PyObjectProtocol`](https://docs.rs/pyo3/0.15.2/pyo3/class/basic/trait.PyObjectProtocol.html).

3087: PEP 623: wstr, wstr_length, state changes r=adamreichold a=ijl
https://peps.python.org/pep-0623/
Following members are removed from the Unicode structures:
wstr
wstr_length
state.compact
state.ready
Note state.compact is still present as of v3.12.0a7.
state.interned has changed width from 2 to 1 bits.

3067: docs: show pattern for self.__class__.__name__ in __repr__ r=adamreichold a=wjones127
It took me a little while to figure out this pattern in PyO3, so I thought it would be a good addition to the guide.
It's not the cleanest pattern, so would welcome suggestions on how to make it shorter or easier.

3015: Implement wrapper for `PyASCIIObject.state` bitfield accesses r=davidhewitt a=decathorpe
This is a first draft of my attempt to fix#1824 "properly" by writing a C wrapper for the `PyASCIIObject.state` bitfield accesses, as proposed here: https://github.com/PyO3/pyo3/issues/1824#issuecomment-1406909504
---
The original argument for making these functions `unsafe` is still valid, though - bitfield memory layout is not guaranteed to be stable across different C compilers, as it is "implementation defined" in the C standard. However, short of having CPython upstream provide non-inlined public functions to access this bitfield, this is the next best thing, as far as I can tell.
I've removed the `#[cfg(target_endian = "little")]` attributes from all things that are un-blocked by fixing this issue on big-endian systems, except for three tests, which look like expected failures considering that they do not take bit/byte order into account (for example, when writing to the bitfield).
- `ffi::tests::ascii_object_bitfield`
- `types::string::tests::test_string_data_ucs2_invalid`
- `types::string::tests::test_string_data_ucs4_invalid`
All other tests now pass on both little-endian and big-endian systems.
---
I am aware that some parts of this PR are probably not in a state that's acceptable for merging as-is, which is why I'm filing this as a draft. Feedback about how to better integrate this change with pyo3-ffi would be great. :)
In particular, I'm unsure whether the `#include` statements in the C files are actually correct across different systems. I have only tested this on Fedora Linux so far.
I'm also open to changing the names of the C functions that are implemented in the wrapper. For now I chose the most obvious names that shouldn't cause collisions with other symbols.

2975: RFC: Add GILProtected synchronization primitive and use it for LazyTypeObjectInner. r=davidhewitt a=adamreichold
I would also like to use that type in rust-numpy and it seems we can avoid ~~both a manual unsafe impl and~~ a full blown mutex if we apply it to `LazyTypeObjectInner`.
One downside might be that it ties us closer to the GIL when we want to enable nogil experimentation, but on the other hand, it may also help by reifying the GIL usage. (This is currently limited to comments in unsafe code in rust-numpy for example.)
3022: Fix function name shadowing r=davidhewitt a=mejrs
Fixes https://github.com/PyO3/pyo3/issues/3017
3023: Emit a better error for bad argument names r=davidhewitt a=mejrs
This will emit a better error for code like
```rust
#[pyfunction]
fn output([a,b,c]: [u8;3]) {}
```

3055: Fix compile error when trying to use static slot methods, fixes: #3039 r=davidhewitt a=willstott101
Whilst having static slot methods is of dubious value in the first place, there's little reason not to support it by bringing the different function call macros more in-line with each other.
I had no idea which test file to use so I just made a new one... `test_methods.rs` has no slots in and the test files that do use slots seem to be specific to their protocol. Let me know if you'd like the test somewhere else.
Thanks!

3044: Add `PyTuple::to_list` r=davidhewitt a=davidhewitt
Companion to #3043. I've included benchmarks which suggests that this method is indeed about 25% faster on my machine.

3056: ci: pin syn to 1.0 for MSRV r=davidhewitt a=davidhewitt
Looks like syn 2.0 requires Rust 1.56 - it'll be interesting for us to update to this one day, but not quite yet!

3049: Add Blog post in Articles and other media section r=messense a=AdilZouitine
Hi there 👋,
This pull request adds a link to a blog post in the PyO3 README under the "Articles and other media" section. The blog post, titled "How we extended the River stats module with Rust using PyO3," details our experience in utilizing PyO3 to improve the performance of the River library's stats module.

3043: `PyList::as_tuple()` -> `PyList::to_tuple()` r=mejrs a=davidhewitt

3042: add `as_tuple()` method to `PyList` r=davidhewitt a=samuelcolvin
From [benchmarks](25fcf98e12/benches/main.rs (L165-L192)), this is significantly faster than `PyTuple::new(py, the_list)`:
```
test list_as_tuple_direct ... bench: 299 ns/iter (+/- 51)
test list_as_tuple_iterate ... bench: 521 ns/iter (+/- 41)
```
