| Remove 4 private trashcan C API functions which were only kept for the backward | ||

Remove 4 C API private trashcan functions which were only kept for the backward compatibility of the stable ABI with Python 3.8 and older, since the trashcan API was not usable with the limited C API on Python 3.8 and older. The trashcan API was excluded from the limited C API in Python 3.9. Removed functions: * _PyTrash_deposit_object() * _PyTrash_destroy_chain() * _PyTrash_thread_deposit_object() * _PyTrash_thread_destroy_chain() The trashcan C API was never usable with the limited C API, since old trashcan macros accessed directly PyThreadState members like "_tstate->trash_delete_nesting", whereas the PyThreadState structure is opaque in the limited C API. Exclude also the PyTrash_UNWIND_LEVEL constant from the C API. The trashcan C API was modified in Python 3.9 by commit 38965ec and in Python 3.10 by commit ed1a5a5 to hide implementation details.

I updated the PR to list the 4 removed functions in the NEWS entry and I also updated the stable ABI. |
|
@encukou: Would you mind to review the updated PR? It now removes the removed functions from the stable ABI. |

Remove 4 C API private trashcan functions which were only kept for
the backward compatibility of the stable ABI with Python 3.8 and
older, since the trashcan API was not usable with the limited C API
on Python 3.8 and older. The trashcan API was excluded from the
limited C API in Python 3.9.
The trashcan C API was never usable with the limited C API, since old
trashcan macros accessed directly PyThreadState members like
"_tstate->trash_delete_nesting", whereas the PyThreadState structure
is opaque in the limited C API.
Exclude also the PyTrash_UNWIND_LEVEL constant from the C API.
The trashcan C API was modified in Python 3.9 by commit
38965ec and in Python 3.10 by commit
ed1a5a5 to hide implementation
details.
