Updates pyo3 from 0.16.5 to 0.16.6

Release notes

Sourced from pyo3's releases.

PyO3 0.16.6

This release is a tactical set of soundness fixes identified for the PyCapsule bindings released in PyO3 0.16. To avoid breaking API changes capsules created with PyCapsule::new and PyCapsule::new_with_destructor will now leak their contents (and not call the destructor) if released on a thread other than the one they were created.

PyO3 0.17 will be released shortly with breaking API changes which resolve the PyCapsule issues with better design (e.g. the destructor has a Send bound added). Users are encouraged to upgrade at their earliest convenience.

Thanks to @​saethlin for reporting the issue, and to @​adamreichold and @​davidhewitt for implementing the resolution.

Changelog

Sourced from pyo3's changelog.

[0.16.6] - 2022-08-23

Changed

• Fix soundness issues with PyCapsule type with select workarounds. Users are encourage to upgrade to PyO3 0.17 at their earliest convenience which contains API breakages which fix the issues in a long-term fashion. #2522
  • PyCapsule::new and PyCapsule::new_with_destructor now take ownership of a copy of the name to resolve a possible use-after-free.
  • PyCapsule::name now returns an empty CStr instead of dereferencing a null pointer if the capsule has no name.
  • The destructor F in PyCapsule::new_with_destructor will never be called if the capsule is deleted from a thread other than the one which the capsule was created in (a warning will be emitted).
• Panics during drop of panic payload caught by PyO3 will now abort. #2544
