[dependabot]

Bumps cffi from 1.15.1 to 1.17.1.

Release notes

Sourced from cffi's releases.

v1.17.1

• Fix failing distutils.msvc9compiler imports under Windows (#118).
• ffibuilder.emit_python_code() and ffibuiler.emit_c_code() accept file-like objects (#115).
• ffiplatform calls are bypassed by ffibuilder.emit_python_code() and ffibuilder.emit_c_code() (#81).

Full Changelog: python-cffi/cffi@v1.17.0...v1.17.1

v1.17.0

• Add support for Python 3.13.
  • Free-threaded CPython builds (i.e. python3.13t and the 3.13t ABI) are not currently supported.
• In API mode, when you get a function from a C library by writing fn = lib.myfunc, you get an object of a special type for performance reasons, instead of a <cdata 'C-function-type'>. Before version 1.17 you could only call such objects. You could write ffi.addressof(lib, "myfunc") in order to get a real <cdata> object, based on the idea that in these cases in C you'd usually write &myfunc instead of myfunc. In version 1.17, the special object lib.myfunc can now be passed in many places where CFFI expects a regular <cdata> object. For example, you can now pass it as a callback to a C function call, or write it inside a C structure field of the correct pointer-to-function type, or use ffi.cast() or ffi.typeof() on it.

v1.17.0rc1

• Add support for Python 3.13.
• In API mode, when you get a function from a C library by writing fn = lib.myfunc, you get an object of a special type for performance reasons, instead of a object. For example, you can now pass it as a callback to a C function call, or write it inside a C structure field of the correct pointer-to-function type, or use ffi.cast() or ffi.typeof() on it.
• Build wheels for musllinux aarch64.

v1.16.0

• Add support for Python 3.12. With the removal of distutils from Python 3.12, projects using CFFI features that depend on distutils at runtime must add a dependency on setuptools to function under Python 3.12+. CFFI does not declare a runtime setuptools requirement to avoid an unnecessary dependency for projects that do not require it.
• Drop support for end-of-life Python versions (2.7, 3.6, 3.7).
• Add support for PEP517 builds; setuptools is now a required build dependency.
• Declare python_requires metadata for Python 3.8+. This allows unsupported Pythons to continue using previously released sdists and wheels.
• Move project source under src/; a more standard layout that also enables CI to more easily catch packaging errors.

v1.16.0rc2

• Fix packaging issue in v1.16.0rc1.
• Rearrange project sources (src/ layout) so packaging tests can properly detect similar issues in the future.
