bpo-38644: Add _PySys_Audit() which takes tstate (GH-19180) Add _PySys_Audit() function to the internal C API: similar to PySys_Audit(), but requires a mandatory tstate parameter. Cleanup sys_audit_tstate() code: remove code path for NULL tstate, since the function exits at entry if tstate is NULL. Remove also code path for NULL tstate->interp: should_audit() now ensures that it is not NULL (even if tstate->interp cannot be NULL in practice). PySys_AddAuditHook() now checks if tstate is not NULL to decide if tstate can be used or not, and tstate is set to NULL if the runtime is not initialized yet. Use _PySys_Audit() in sysmodule.c.

gh-106320: Remove private _PySys functions (#108452) Move private functions to the internal C API (pycore_sysmodule.h): * _PySys_GetAttr() * _PySys_GetSizeOf() No longer export most of these functions. Fix also a typo in Include/cpython/optimizer.h: add a missing space.

bpo-46541: Replace core use of _Py_IDENTIFIER() with statically initialized global objects. (gh-30928) We're no longer using _Py_IDENTIFIER() (or _Py_static_string()) in any core CPython code. It is still used in a number of non-builtin stdlib modules. The replacement is: PyUnicodeObject (not pointer) fields under _PyRuntimeState, statically initialized as part of _PyRuntime. A new _Py_GET_GLOBAL_IDENTIFIER() macro facilitates lookup of the fields (along with _Py_GET_GLOBAL_STRING() for non-identifier strings). https://bugs.python.org/issue46541#msg411799 explains the rationale for this change. The core of the change is in: * (new) Include/internal/pycore_global_strings.h - the declarations for the global strings, along with the macros * Include/internal/pycore_runtime_init.h - added the static initializers for the global strings * Include/internal/pycore_global_objects.h - where the struct in pycore_global_strings.h is hooked into _PyRuntimeState * Tools/scripts/generate_global_objects.py - added generation of the global string declarations and static initializers I've also added a --check flag to generate_global_objects.py (along with make check-global-objects) to check for unused global strings. That check is added to the PR CI config. The remainder of this change updates the core code to use _Py_GET_GLOBAL_IDENTIFIER() instead of _Py_IDENTIFIER() and the related _Py*Id functions (likewise for _Py_GET_GLOBAL_STRING() instead of _Py_static_string()). This includes adding a few functions where there wasn't already an alternative to _Py*Id(), replacing the _Py_Identifier * parameter with PyObject *. The following are not changed (yet): * stop using _Py_IDENTIFIER() in the stdlib modules * (maybe) get rid of _Py_IDENTIFIER(), etc. entirely -- this may not be doable as at least one package on PyPI using this (private) API * (maybe) intern the strings during runtime init https://bugs.python.org/issue46541

gh-101758: Clean Up Uses of Import State (gh-101919) This change is almost entirely moving code around and hiding import state behind internal API. We introduce no changes to behavior, nor to non-internal API. (Since there was already going to be a lot of churn, I took this as an opportunity to re-organize import.c into topically-grouped sections of code.) The motivation is to simplify a number of upcoming changes. Specific changes: * move existing import-related code to import.c, wherever possible * add internal API for interacting with import state (both global and per-interpreter) * use only API outside of import.c (to limit churn there when changing the location, etc.) * consolidate the import-related state of PyInterpreterState into a single struct field (this changes layout slightly) * add macros for import state in import.c (to simplify changing the location) * group code in import.c into sections *remove _PyState_AddModule() https://github.com/python/cpython/issues/101758

gh-107954, PEP 741: Add PyConfig_Get()/Set() functions (#123472) Add PyConfig_Get(), PyConfig_GetInt(), PyConfig_Set() and PyConfig_Names() functions to get and set the current runtime Python configuration. Add visibility and "sys spec" to config and preconfig specifications. _PyConfig_AsDict() now converts PyConfig.xoptions as a dictionary.
