* bpo-43931: Export Python version as API data (GH-25577)Gabriele N. Tornetta2021-12-101-0/+3
| | | | | When Python is embedded in other applications, it is not easy to determine which version of Python is being used. This change exposes the Python version as part of the API data. Tools like Austin (https://github.com/P403n1x87/austin) can benefit from this data when targeting applications like uWSGI, as the Python version can then be inferred systematically by looking at the exported symbols rather than relying on unreliable pattern matching or other hacks (like remote code execution etc...).

| | | | | | | | | | | | | | | | | | | before GC header. (GH-29879) * Place __dict__ immediately before GC header for plain Python objects. * Fix up lazy dict creation logic to use managed dict pointers. * Manage values pointer, placing them directly before managed dict pointers. * Convert hint-based load/store attr specialization target managed dict classes. * Specialize LOAD_METHOD for managed dict objects. * Remove unsafe _PyObject_GC_Calloc function. * Remove unsafe _PyObject_GC_Malloc() function. * Add comment explaning use of Py_TPFLAGS_MANAGED_DICT.

| | | | | | | | Fix PyAiter_Check to only check for the `__anext__` presense (not for `__aiter__`). Rename `PyAiter_Check()` to `PyAIter_Check()`, `PyObject_GetAiter()` -> `PyObject_GetAIter()`. Co-authored-by: Pablo Galindo Salgado <Pablogsal@gmail.com>

* bpo-39947: Remove old private trashcan C API functions (GH-26869)Victor Stinner2021-06-231-12/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | 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 38965ec5411da60d312b59be281f3510d58e0cf1 and in Python 3.10 by commit ed1a5a5baca8f61e9a99c5be3adc16b1801514fe to hide implementation details.

* bpo-43795: Don't list private names in the limited API (GH-26740)Petr Viktorin2021-06-161-3/+1
| | | | | | | | | | | | | * Remove struct _node from the stable ABI list This struct was removed along with the old parser in Python 3.9 (PEP 617) * Stable ABI list: Use the public name "PyFrameObject" rather than "_frame" * Ensure limited API doesn't contain private names Names prefixed by an underscore are private by definition. * Add a blurb
* bpo-43795: Remove Py_FrozenMain from the Limited API & Stable ABI (GH-26241)Petr Viktorin2021-05-251-2/+0
| | | | | | | | | | | Py_FrozenMain was added to the Limited C API in [bpo-42591]() (3.10.0a4); but to fix that issue it would be enough to add it to the regular C API. The function is undocumented, tests were added very recently ([bpo-44131]()), and most importantly, it is not present in all builds of Python, as the linker sometimes omits it as unused. It should be added back when these issues are fixed. Note that this does not affect Python's regular C API.
