While not strictly necessary for enabling\nfree-threaded builds, it makes adding support more straighforward and\nsets the stage for both PEP 793 [1] which soft-deprecates PyInit_* and\nPEP 803 [2] which could simplify wheel builds.\n\nPatches have been tested against the full matrix of supported versions:\n https://github.com/vfazio/libgpiod/actions/runs/24860932220\n\n[0]: https://peps.python.org/pep-0489/\n[1]: https://peps.python.org/pep-0793/\n[2]: https://peps.python.org/pep-0803/\n\nSigned-off-by: Vincent Fazio <vfazio@gmail.com>\n---\nChanges in v2:\n- Dropped \"bindings: python: use Py_RETURN_NONE in chip_get_line_name\" (Bartosz)\n- Adjusted patch 4 to simplify Py_None strong reference acquisition\n- Updated link to passing pipeline\n- Link to v1: https://lore.kernel.org/all/20260422012041.39933-1-vfazio@gmail.com/\n---\n\nVincent Fazio (8):\n bindings: python: avoid PyObject_CallMethod during chip finalize\n bindings: python: avoid PyObject_CallMethod during request finalize\n bindings: python: simplify disallowing _ext.Request from being created\n bindings: python: use suggestions from upgrade_pythoncapi.py\n bindings: python: use PyImport_ImportModuleAttrString when available\n bindings: python: migrate the gpiod._ext module to multi-phase init\n bindings: python: tests: migrate the system module to multi-phase init\n bindings: python: tests: migrate the gpiosim module to multi-phase\n init\n\n bindings/python/gpiod/ext/chip.c | 29 ++---\n bindings/python/gpiod/ext/common.c | 5 +-\n bindings/python/gpiod/ext/internal.h | 10 +-\n bindings/python/gpiod/ext/module.c | 68 ++++++------\n bindings/python/gpiod/ext/request.c | 26 ++---\n bindings/python/tests/gpiosim/ext.c | 153 +++++++++++++++++----------\n bindings/python/tests/system/ext.c | 7 +-\n 7 files changed, 171 insertions(+), 127 deletions(-)" }
