Added gil_scoped_release support to functions using a regex as acl

[gfabiano]

Added the support of py::call_guard<py::gil_scoped_release>() on generated def to fix some edge cases where the gil deadlock when calling a c++ function. In pybind and nanobind, there is the gil_scoped_release directive to handle this.

I implemented fn_add_gil_scoped_release_guard__regex to enable the call guards for the functions that needs that.

Very nice, thanks!

Could you add a test inside src/litgen/tests/internal/adapted_types/adapted_function_test.py

Did you test it with pybind11 and nanobind? I looked at the doc, and saw that both seem to support this.

[gfabiano]

Yes, I already considered nanobind. I added two tests to validate generation for both nanobind and pybind11.

This was perfetto ! Thanks a lot.

Sorry to bother you, but when I can expect a release on PyPI? this pull request derive from a issue I had and it will be good to only change version of litgen in my environment

[pthom]

I just created a release (v0.22.0).

Out of curiosity, could you tell me more about how and where you are using litgen (I'm always interested to know how people are using my projects :-)

[gfabiano]

Thank you!

Yes, briefly, in my company, we have to qualify our C++ software under SWE.6 (automotive). So we are developing a Python suite for that. We use litgen to generate bindings between the real software that exposes the API and the test suite in Python. Before, without litgen this part was made manually on each software we had to test.
