* Use static inline function Py_EnterRecursiveCall() (#91988)Victor Stinner2022-05-041-9/+9
| | | | | | | | | | | | | | | | 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()

* bpo-46541: Replace core use of _Py_IDENTIFIER() with statically initialized ↵Eric Snow2022-02-081-22/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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
* docs: correct outdated MappingProxyType docstrings (#30281)Joshua Bronson2022-01-191-3/+3
| | | | | The docstrings for MappingProxyType's keys(), values(), and items() methods were never updated to reflect the changes that Python 3 brought to these APIs, namely returning views rather than lists.
* bpo-45385: Fix reference leak from descr_check (#28719)Dong-hee Na2021-10-071-39/+37

* Clean up initialization __class_getitem__ with Py_GenericAlias. (GH-28450)Serhiy Storchaka2021-09-191-1/+1
| | | | | The cast to PyCFunction is redundant. Overuse of redundant casts can hide actual bugs.
* bpo-44661: Update property_descr_set to use vectorcall if possible. (GH-27206)Dong-hee Na2021-07-191-7/+18

* bpo-43977: Use tp_flags for collection matching (GH-25723)Mark Shannon2021-04-301-1/+2
| | | | | | | | | | | | | * Add Py_TPFLAGS_SEQUENCE and Py_TPFLAGS_MAPPING, add to all relevant standard builtin classes. * Set relevant flags on collections.abc.Sequence and Mapping. * Use flags in MATCH_SEQUENCE and MATCH_MAPPING opcodes. * Inherit Py_TPFLAGS_SEQUENCE and Py_TPFLAGS_MAPPING. * Add NEWS * Remove interpreter-state map_abc and seq_abc fields.

* bpo-42800: add audit hooks for f_code and tb_frame (GH-24182)Ryan Hileman2021-04-291-1/+1
| | | | | | | | | | Accessing the following attributes will now fire PEP 578 style audit hooks as ("object.__getattr__", obj, name): * PyTracebackObject: tb_frame * PyFrameObject: f_code * PyGenObject: gi_code, gi_frame * PyCoroObject: cr_code, cr_frame * PyAsyncGenObject: ag_code, ag_frame Add an AUDIT_READ attribute flag aliased to READ_RESTRICTED. Update obsolete flag documentation.

* bpo-38787: C API for module state access from extension methods (PEP 573) ↵Petr Viktorin2020-05-071-3/+44
| | | | | | | | | (GH-19936) Module C state is now accessible from C-defined heap type methods (PEP 573). Patch by Marcel Plch and Petr Viktorin. Co-authored-by: Marcel Plch <mplch@redhat.com> Co-authored-by: Victor Stinner <vstinner@python.org>
* bpo-40268: Remove unused structmember.h includes (GH-19530)Victor Stinner2020-04-151-1/+1
| | | | | | If only offsetof() is needed: include stddef.h instead. When structmember.h is used, add a comment explaining that PyMemberDef is used.
* bpo-40268: Remove a few pycore_pystate.h includes (GH-19510)Victor Stinner2020-04-141-2/+2

* bpo-39481: Implementation for PEP 585 (#18239)Guido van Rossum2020-04-071-0/+2
| | | | | | | | | | | | This implements things like `list[int]`, which returns an object of type `types.GenericAlias`. This object mostly acts as a proxy for `list`, but has attributes `__origin__` and `__args__` that allow recovering the parts (with values `list` and `(int,)`. There is also an approximate notion of type variables; e.g. `list[T]` has a `__parameters__` attribute equal to `(T,)`. Type variables are objects of type `typing.TypeVar`.
* bpo-39947: Move Py_EnterRecursiveCall() to internal C API (GH-18972)Victor Stinner2020-03-131-0/+1
| | | | | | Move the static inline function flavor of Py_EnterRecursiveCall() and Py_LeaveRecursiveCall() to the internal C API: they access PyThreadState attributes. The limited C API provides regular functions which hide implementation details.
* bpo-39884: Add method name in "bad call flags" error (GH-18944)Victor Stinner2020-03-121-1/+2
| | | | PyDescr_NewMethod() and PyCFunction_NewEx() now include the method name in the SystemError "bad call flags" error message to ease debug.
* bpo-36144: Update MappingProxyType with PEP 584's operators (#18814)Brandt Bucher2020-03-071-1/+25
| | | We make `|=` raise TypeError, since it would be surprising if `C.__dict__ |= {'x': 0}` silently did nothing, while `C.__dict__.update({'x': 0})` is an error.

* bpo-39245: Switch to public API for Vectorcall (GH-18460)Petr Viktorin2020-02-111-4/+4

* bpo-39573: Use Py_TYPE() macro in Objects directory (GH-18392)Victor Stinner2020-02-071-7/+7
| | | Replace direct access to PyObject.ob_type with Py_TYPE().
* bpo-39487: Merge duplicated _Py_IDENTIFIER identifiers in C code (GH-18254)Hai Shi2020-01-301-2/+2
| | | Moving repetitive `_Py_IDENTIFIER` instances to a global location helps identify them more easily in regards to sub-interpreter support.
* bpo-37645: add new function _PyObject_FunctionStr() (GH-14890)Jeroen Demeyer2019-11-051-28/+29
| | | | | | | | | | | | Additional note: the `method_check_args` function in `Objects/descrobject.c` is written in such a way that it applies to all kinds of descriptors. In particular, a future re-implementation of `wrapper_descriptor` could use that code. CC @vstinner @encukou https://bugs.python.org/issue37645 Automerge-Triggered-By: @encukou
* bpo-38644: Pass tstate to Py_EnterRecursiveCall() (GH-16997)Victor Stinner2019-11-041-14/+20
| | | | | | | | | | | | | * Add _Py_EnterRecursiveCall() and _Py_LeaveRecursiveCall() which require a tstate argument. * Pass tstate to _Py_MakeRecCheck() and _Py_CheckRecursiveCall(). * Convert Py_EnterRecursiveCall() and Py_LeaveRecursiveCall() macros to static inline functions. _PyThreadState_GET() is the most efficient way to get the tstate, and so using it with _Py_EnterRecursiveCall() and _Py_LeaveRecursiveCall() should be a little bit more efficient than using Py_EnterRecursiveCall() and Py_LeaveRecursiveCall() which use the "slower" PyThreadState_GET().
* bpo-37994: Fix silencing all errors if an attribute lookup fails. (GH-15630)Serhiy Storchaka2019-09-011-19/+15
