* [3.11] gh-112716: Fix SystemError when __builtins__ is not a dict ↵Serhiy Storchaka2023-12-141-9/+5
| | | | | | | | | (GH-112770) (GH-113105) It was raised in two cases: * in the import statement when looking up __import__ * in pickling some builtin type when looking up built-ins iter, getattr, etc. (cherry picked from commit 1161c14e8c68296fc465cd48970b32be9bee012e)

* [3.11] gh-104690: thread_run() checks for tstate dangling pointer (#109056) ↵Victor Stinner2023-09-081-20/+6
| | | | | | | | | | | | | | (#109134) gh-104690: thread_run() checks for tstate dangling pointer (#109056) thread_run() of _threadmodule.c now calls _PyThreadState_CheckConsistency() to check if tstate is a dangling pointer when Python is built in debug mode. Rename ceval_gil.c is_tstate_valid() to _PyThreadState_CheckConsistency() to reuse it in _threadmodule.c. (cherry picked from commit f63d37877ad166041489a968233b57540f8456e8)

| | | | | | | | | | | | | | | | | | Move the follow functions and type from frameobject.h to pyframe.h, so the standard <Python.h> provide frame getter functions: * PyFrame_Check() * PyFrame_GetBack() * PyFrame_GetBuiltins() * PyFrame_GetGenerator() * PyFrame_GetGlobals() * PyFrame_GetLasti() * PyFrame_GetLocals() * PyFrame_Type Remove #include "frameobject.h" from many C files.

* [3.11] bpo-40514: Drop EXPERIMENTAL_ISOLATED_SUBINTERPRETERS (gh-93185) ↵Eric Snow2022-05-281-55/+0
| | | | | | | | | | | | | (GH-93306) (cherry picked from commit caa279d6fd5f151e57f891cd4f6ba51b532501c6) This was added for bpo-40514 (gh-84694) to test out a per-interpreter GIL. However, it has since proven unnecessary to keep the experiment in the repo. (It can be done as a branch in a fork like normal.) So here we are removing: * the configure option * the macro * the code enabled by the macro Automerge-Triggered-By: GH:ericsnowcurrently
* gh-91924: Fix __lltrace__ for non-UTF-8 stdout encoding (GH-93199)Miss Islington (bot)2022-05-251-1/+3
| | | | | | | | | | | Fix __lltrace__ debug feature if the stdout encoding is not UTF-8. If the stdout encoding is not UTF-8, the first call to lltrace_resume_frame() indirectly sets lltrace to 0 when calling unicode_check_encoding_errors() which calls encodings.search_function().

* Use static inline function Py_EnterRecursiveCall() (#91988)Victor Stinner2022-05-041-15/+15
| | | | | | | | | | | | | | | | 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()

* gh-89279: In ceval.c, redefine some macros for speed (#32387)Guido van Rossum2022-04-221-13/+60
| | | | | | | | | | | Macros Py_DECREF, Py_XDECREF, Py_IS_TYPE, _Py_atomic_load_32bit_impl and _Py_DECREF_SPECIALIZED are redefined as macros that completely replace the inline functions of the same name. These three came out in the top four of functions that (in MSVC) somehow weren't inlined.

* GH-91719: Make MSVC generate somewhat faster switch code (#91718)Guido van Rossum2022-04-211-2/+4
| | | | | | | | | | | Apparently a switch on an 8-bit quantity where all cases are present generates a more efficient jump (doing only one indexed 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. See https://github.com/faster-cpython/ideas/issues/321#issuecomment-1103263673
