9f1187f97c Add typing.SupportsIndex to int/float/complex type hints (#5891)
* Add typing.SupportsIndex to int/float/complex type hints

This corrects a mistake where these types were supported but the type
hint was not updated to reflect that SupportsIndex objects are accepted.

To track the resulting test failures:

The output of

"$(cat PYROOT)"/bin/python3 $HOME/clone/pybind11_scons/run_tests.py $HOME/forked/pybind11 -v

is in

~/logs/pybind11_pr5879_scons_run_tests_v_log_2025-11-10+122217.txt

* Cursor auto-fixes (partial) plus pre-commit cleanup. 7 test failures left to do.

* Fix remaining test failures, partially done by cursor, partially manually.

* Cursor-generated commit: Added the Index() tests from PR 5879.

Summary:

  Changes Made

  1. **C++ Bindings** (`tests/test_builtin_casters.cpp`)

  • Added complex_convert and complex_noconvert functions needed for the tests

  2. **Python Tests** (`tests/test_builtin_casters.py`)

  `test_float_convert`:
  • Added Index class with __index__ returning -7
  • Added Int class with __int__ returning -5
  • Added test showing Index() works with convert mode: assert pytest.approx(convert(Index())) == -7.0
  • Added test showing Index() doesn't work with noconvert mode: requires_conversion(Index())
  • Added additional assertions for int literals and Int() class

  `test_complex_cast`:
  • Expanded the test to include convert and noconvert functionality
  • Added Index, Complex, Float, and Int classes
  • Added test showing Index() works with convert mode: assert convert(Index()) == 1 and assert isinstance(convert(Index()), complex)
  • Added test showing Index() doesn't work with noconvert mode: requires_conversion(Index())
  • Added type hint assertions matching the SupportsIndex additions

  These tests demonstrate that custom __index__ objects work with float and complex in convert mode, matching the typing.SupportsIndex type hint added in PR
  5891.

* Reflect behavior changes going back from PR 5879 to master. This diff will have to be reapplied under PR 5879.

* Add PyPy-specific __index__ handling for complex caster

Extract PyPy-specific __index__ backporting from PR 5879 to fix PyPy 3.10
test failures in PR 5891. This adds:

1. PYBIND11_INDEX_CHECK macro in detail/common.h:
   - Uses PyIndex_Check on CPython
   - Uses hasattr check on PyPy (workaround for PyPy 7.3.3 behavior)

2. PyPy-specific __index__ handling in complex.h:
   - Handles __index__ objects on PyPy 7.3.7's 3.8 which doesn't
     implement PyLong_*'s __index__ calls
   - Mirrors the logic used in numeric_caster for ints and floats

This backports __index__ handling for PyPy, matching the approach
used in PR 5879's expand-float-strict branch.

391c75447d Update all remaining tests to new test styles
This udpates all the remaining tests to the new test suite code and
comment styles started in #898.  For the most part, the test coverage
here is unchanged, with a few minor exceptions as noted below.

- test_constants_and_functions: this adds more overload tests with
  overloads with different number of arguments for more comprehensive
  overload_cast testing.  The test style conversion broke the overload
  tests under MSVC 2015, prompting the additional tests while looking
  for a workaround.

- test_eigen: this dropped the unused functions `get_cm_corners` and
  `get_cm_corners_const`--these same tests were duplicates of the same
  things provided (and used) via ReturnTester methods.

- test_opaque_types: this test had a hidden dependence on ExampleMandA
  which is now fixed by using the global UserType which suffices for the
  relevant test.

- test_methods_and_attributes: this required some additions to UserType
  to make it usable as a replacement for the test's previous SimpleType:
  UserType gained a value mutator, and the `value` property is not
  mutable (it was previously readonly).  Some overload tests were also
  added to better test overload_cast (as described above).

- test_numpy_array: removed the untemplated mutate_data/mutate_data_t:
  the templated versions with an empty parameter pack expand to the same
  thing.

- test_stl: this was already mostly in the new style; this just tweaks
  things a bit, localizing a class, and adding some missing
  `// test_whatever` comments.

- test_virtual_functions: like `test_stl`, this was mostly in the new
  test style already, but needed some `// test_whatever` comments.
  This commit also moves the inherited virtual example code to the end
  of the file, after the main set of tests (since it is less important
  than the other tests, and rather length); it also got renamed to
  `test_inherited_virtuals` (from `test_inheriting_repeat`) because it
  tests both inherited virtual approaches, not just the repeat approach.

f3ce00eaed vectorize: pass-through of non-vectorizable args
This extends py::vectorize to automatically pass through
non-vectorizable arguments.  This removes the need for the documented
"explicitly exclude an argument" workaround.

Vectorization now applies to arithmetic, std::complex, and POD types,
passed as plain value or by const lvalue reference (previously only
pass-by-value types were supported).  Non-const lvalue references and
any other types are passed through as-is.

Functions with rvalue reference arguments (whether vectorizable or not)
are explicitly prohibited: an rvalue reference is inherently not
something that can be passed multiple times and is thus unsuitable to
being in a vectorized function.

The vectorize returned value is also now more sensitive to inputs:
previously it would return by value when all inputs are of size 1; this
is now amended to having all inputs of size 1 *and* 0 dimensions.  Thus
if you pass in, for example, [[1]], you get back a 1x1, 2D array, while
previously you got back just the resulting single value.

Vectorization of member function specializations is now also supported
via `py::vectorize(&Class::method)`; this required passthrough support
for the initial object pointer on the wrapping function pointer.

b0292c1df3 vectorize: trivial handling for F-order arrays
This extends the trivial handling to support trivial handling for
Fortran-order arrays (i.e. column major): if inputs aren't all
C-contiguous, but *are* all F-contiguous, the resulting array will be
F-contiguous and we can do trivial processing.

For anything else (e.g. C-contiguous, or inputs requiring non-trivial
processing), the result is in (numpy-default) C-contiguous layout.

ae5a8f7eb3 Stop forcing c-contiguous in py::vectorize
The only part of the vectorize code that actually needs c-contiguous is
the "trivial" broadcast; for non-trivial arguments, the code already
uses strides properly (and so handles C-style, F-style, neither, slices,
etc.)

This commit rewrites `broadcast` to additionally check for C-contiguous
storage, then takes off the `c_style` flag for the arguments, which
will keep the functionality more or less the same, except for no longer
requiring an array copy for non-c-contiguous input arrays.

Additionally, if we're given a singleton slice (e.g. a[0::4, 0::4] for a
4x4 or smaller array), we no longer fail triviality because the trivial
code path never actually uses the strides on a singleton.

2a75784420 Move requires_numpy, etc. decorators to globals
test_eigen.py and test_numpy_*.py have the same
@pytest.requires_eigen_and_numpy or @pytest.requires_numpy on every
single test; this changes them to use pytest's global `pytestmark = ...`
instead to disable the entire module when numpy and/or eigen aren't
available.

665e8804f3 Simplify tests by replacing output capture with asserts where possible
The C++ part of the test code is modified to achieve this. As a result,
this kind of test:

```python
with capture:
    kw_func1(5, y=10)
assert capture == "kw_func(x=5, y=10)"
```

can be replaced with a simple:

`assert kw_func1(5, y=10) == "x=5, y=10"`

a0c1ccf0a9 Port tests to pytest
Use simple asserts and pytest's powerful introspection to make testing
simpler. This merges the old .py/.ref file pairs into simple .py files
where the expected values are right next to the code being tested.

This commit does not touch the C++ part of the code and replicates the
Python tests exactly like the old .ref-file-based approach.
