gh-89653: Add assertions to unicodeobject.h functions (#92692) 2022-05-12 00:12:42 +02:00

gh-89653: PEP 670: Limited API doesn't cast arguments (#92654)
The limited API version 3.11 no longer casts arguments to expected
types of functions of functions:

* PyList_GET_SIZE(), PyList_SET_ITEM()
* PyTuple_GET_SIZE(), PyTuple_SET_ITEM()
* PyWeakref_GET_OBJECT()

gh-89653: PEP 670: Convert unicodeobject.h macros to functions (#92648)
Convert the following Unicode macros to static inline functions.

Surrogate functions:

* Py_UNICODE_IS_SURROGATE()
* Py_UNICODE_IS_HIGH_SURROGATE()
* Py_UNICODE_IS_LOW_SURROGATE()
* Py_UNICODE_HIGH_SURROGATE()
* Py_UNICODE_LOW_SURROGATE()
* Py_UNICODE_JOIN_SURROGATES()

"Is" functions:

* Py_UNICODE_ISALNUM()
* Py_UNICODE_ISSPACE()

In the implementation of these functions, the character type is now
well defined to Py_UCS4.

gh-89653: PEP 670: Convert PyCell macros to functions (#92653)
Convert the following macros to static inline functions:

* PyCell_GET()
* PyCell_SET()

Limited C API version 3.12 no longer casts arguments.

Fix also usage of PyCell_SET(): only delete the old value after
setting the new value.

gh-92651: Remove the Include/token.h header file (#92652)
Remove the token.h header file. There was never any public tokenizer
C API. The token.h header file was only designed to be used by Python
internals.

Move Include/token.h to Include/internal/pycore_token.h. Including
this header file now requires that the Py_BUILD_CORE macro is
defined. It no longer checks for the Py_LIMITED_API macro.

Rename functions:

* PyToken_OneChar() => _PyToken_OneChar()
* PyToken_TwoChars() => _PyToken_TwoChars()
* PyToken_ThreeChars() => _PyToken_ThreeChars()

gh-89653: PEP 670: Convert pycore_gc.h macros to functions (#92649)
Convert the following macros to static inline functions:

* _Py_AS_GC()
* _PyGCHead_FINALIZED(), _PyGCHead_SET_FINALIZED()
* _PyGCHead_NEXT(), _PyGCHead_SET_NEXT()
* _PyGCHead_PREV(), _PyGCHead_SET_PREV()
* _PyGC_FINALIZED(), _PyGC_SET_FINALIZED()
* _PyObject_GC_IS_TRACKED()
* _PyObject_GC_MAY_BE_TRACKED()

Add a macro wrapping the _PyObject_GC_IS_TRACKED() function to cast
the argument to PyObject*.

Use static inline function Py_EnterRecursiveCall() (#91988)
Currently, calling Py_EnterRecursiveCall() and
Py_LeaveRecursiveCall() may use a function call or a static inline
function call, depending if the internal pycore_ceval.h header file
is included or not. Use a different name for the static inline
function to ensure that the static inline function is always used in
Python internals for best performance. Similar approach than
PyThreadState_GET() (function call) and _PyThreadState_GET() (static
inline function).

* Rename _Py_EnterRecursiveCall() to _Py_EnterRecursiveCallTstate()
* Rename _Py_LeaveRecursiveCall() to _Py_LeaveRecursiveCallTstate()
* pycore_ceval.h: Rename Py_EnterRecursiveCall() to
  _Py_EnterRecursiveCall() and Py_LeaveRecursiveCall() and
  _Py_LeaveRecursiveCall()

    ‘PyObject*’ {aka ‘struct _object*’} [-Werror=old-style-cast]
    #define _PyObject_CAST(op) ((PyObject*)(op))

gh-89653: PEP 670: Functions don't cast pointers (#91697)
In the limited C API version 3.11 and newer, the following functions
no longer cast their object pointer argument with _PyObject_CAST() or
_PyObject_CAST_CONST():

* Py_REFCNT(), Py_TYPE(), Py_SIZE()
* Py_SET_REFCNT(), Py_SET_TYPE(), Py_SET_SIZE()
* Py_IS_TYPE()
* Py_INCREF(), Py_DECREF()
* Py_XINCREF(), Py_XDECREF()
* Py_NewRef(), Py_XNewRef()
* PyObject_TypeCheck()
* PyType_Check()
* PyType_CheckExact()

Split Py_DECREF() implementation in 3 versions to make the code more
readable.

Update the xxlimited.c extension, which uses the limited C API
version 3.11, to pass PyObject* to these functions.

GH-91719: Make MSVC generate somewhat faster switch code (#91718)
Apparently a switch on an 8-bit quantity where all cases are

memory load instead of two).

So we make opcode and use_tracing uint8_t, and generate a macro
full of extra `case NNN:` lines for all unused opcodes.

bpo-44800: Document internal frame naming conventions (GH-32281)
The fact interpreter frames were split out from full frame objects
rather than always being part of the eval loop implementation means
that it's tricky to infer the expected naming conventions simply
from looking at the code.

Documenting the de facto conventions in pycore_frame.h means future
readers of the code will have a clear explanation of the rationale
for those conventions (i.e. minimising non-functional code churn).

bpo-45490: Rename static inline functions (GH-31217)
When a static inline function is wrapped by a macro which casts its
arguments to the expected type, there is no need that the function
has a different name than the macro. Use the same name for the macro
and the function to avoid confusion.

Rename _PyUnicode_get_wstr_length() to PyUnicode_WSTR_LENGTH().

Don't rename static inline _Py_NewRef() and _Py_XNewRef() functions,
since the C API exports Py_NewRef() and Py_XNewRef() functions as
regular functions. The name cannot be reused in this case.

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

bpo-46608: exclude marshalled-frozen data if deep-freezing to save 300 KB space (GH-31074)
This reduces the size of the data segment by **300 KB** of the executable because if the modules are deep-frozen then the marshalled frozen data just wastes space. This was inspired by comment by @gvanrossum in https://github.com/python/cpython/pull/29118#issuecomment-958521863. Note: There is a new option `--deepfreeze-only` in `freeze_modules.py` to change this behavior, it is on be default to save disk space.
