* gh-108634: PyInterpreterState_New() no longer calls Py_FatalError() (#108748)Victor Stinner2023-09-017-51/+99
| | | | | | | | | | | | pycore_create_interpreter() now returns a status, rather than calling Py_FatalError(). * PyInterpreterState_New() now calls Py_ExitStatusException() instead of calling Py_FatalError() directly. * Replace Py_FatalError() with PyStatus in init_interpreter() and _PyObject_InitState(). * _PyErr_SetFromPyStatus() now raises RuntimeError, instead of ValueError. It can now call PyErr_NoMemory(), raise MemoryError, if it detects _PyStatus_NO_MEMORY() error message.

* gh-106320: Remove private _PyLong_Sign() (#108743)Victor Stinner2023-09-014-15/+23
| | | | | | Move the private _PyLong_Sign() and _PyLong_NumBits() functions to the internal C API (pycore_long.h). Modules/_testcapi/long.c now uses the internal C API.
* `ast` docs: Fix incorrect link on `keyword` (#108728)Alex Povel2023-08-311-2/+2
| | | In two places, Sphinx was erroneously adding links to the `keyword` module instead of the `ast.keyword` class
* gh-107603: Argument Clinic: Only include pycore_gc.h if needed (#108726)Victor Stinner2023-08-31131-727/+448
| | | | | | | | | | | | | | | | | | | | Argument Clinic now only includes pycore_gc.h if PyGC_Head is needed, and only includes pycore_runtime.h if _Py_ID() is needed. * Add 'condition' optional argument to Clinic.add_include(). * deprecate_keyword_use() includes pycore_runtime.h when using the _PyID() function. * Fix rendering of includes: comments start at the column 35. * Mark PC/clinic/_wmimodule.cpp.h and "Objects/stringlib/clinic/*.h.h" header files as generated in .gitattributes. Effects: * 42 header files generated by AC no longer include the internal C API, instead of 4 header files before. For example, Modules/clinic/_abc.c.h no longer includes the internal C API. * Fix _testclinic_depr.c.h: it now always includes pycore_runtime.h to get _Py_ID().
* gh-108337: Add pyatomic.h header (#108701)Victor Stinner2023-08-3117-4/+3049
| | | | | | | | This adds a new header that provides atomic operations on common data types. The intention is that this will be exposed through Python.h, although that is not the case yet. The only immediate use is in the test file. Co-authored-by: Sam Gross <colesbury@gmail.com>
* gh-108638: Fix tests when _stat extension is missing (#108689)Victor Stinner2023-08-312-7/+29
| | | | Fix test_inspect and test_pydoc when the _stat extension is missing. Skip tests relying on _stat when _stat is missing.
* gh-108682: [Enum] raise TypeError if super().__new__ called in custom ↵Ethan Furman2023-08-314-56/+260
| | | | | | | | | | | __new__ (GH-108704) When overriding the `__new__` method of an enum, the underlying data type should be created directly; i.e. . member = object.__new__(cls) member = int.__new__(cls, value) member = str.__new__(cls, value) Calling `super().__new__()` finds the lookup version of `Enum.__new__`, and will now raise an exception when detected.
* gh-108634: Py_TRACE_REFS uses a hash table (#108663)Victor Stinner2023-08-3131-243/+292
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Python built with "configure --with-trace-refs" (tracing references) is now ABI compatible with Python release build and debug build. Moreover, it now also supports the Limited API. Change Py_TRACE_REFS build: * Remove _PyObject_EXTRA_INIT macro. * The PyObject structure no longer has two extra members (_ob_prev and _ob_next). * Use a hash table (_Py_hashtable_t) to trace references (all objects): PyInterpreterState.object_state.refchain. * Py_TRACE_REFS build is now ABI compatible with release build and debug build. * Limited C API extensions can now be built with Py_TRACE_REFS: xxlimited, xxlimited_35, _testclinic_limited. * No longer rename PyModule_Create2() and PyModule_FromDefAndSpec2() functions to PyModule_Create2TraceRefs() and PyModule_FromDefAndSpec2TraceRefs(). * _Py_PrintReferenceAddresses() is now called before finalize_interp_delete() which deletes the refchain hash table. * test_tracemalloc find_trace() now also filters by size to ignore the memory allocated by _PyRefchain_Trace(). Test changes for Py_TRACE_REFS: * Add test.support.Py_TRACE_REFS constant. * Add test_sys.test_getobjects() to test sys.getobjects() function. * test_exceptions skips test_recursion_normalizing_with_no_memory() and test_memory_error_in_PyErr_PrintEx() if Python is built with Py_TRACE_REFS. * test_repl skips test_no_memory(). * test_capi skisp test_set_nomemory().

* gh-106320: Remove private _PyErr_ChainExceptions() (#108713)Victor Stinner2023-08-3118-117/+140
| | | | | | | | | | | | | Remove _PyErr_ChainExceptions(), _PyErr_ChainExceptions1() and _PyErr_SetFromPyStatus() functions from the public C API. * Move the private _PyErr_ChainExceptions() and _PyErr_ChainExceptions1() function to the internal C API (pycore_pyerrors.h). * Move the private _PyErr_SetFromPyStatus() to the internal C API (pycore_initconfig.h). * No longer export the _PyErr_ChainExceptions() function. * Move run_in_subinterp_with_config() from _testcapi to _testinternalcapi.

* gh-106320: Don't export _Py_ForgetReference() function (#108712)Victor Stinner2023-08-311-2/+8
| | | | | There is no need to export the _Py_ForgetReference() function of the Py_TRACE_REFS build. It's not used by shared extensions. Enhance also its comment.
* gh-107149: Make PyUnstable_ExecutableKinds public (#108440)Victor Stinner2023-08-313-14/+14
| | | | | | Move PyUnstable_ExecutableKinds and associated macros from the internal C API to the public C API. Rename constants: replace "PY_" prefix with "PyUnstable_" prefix.

* gh-108297: Remove test_crashers (#108690)Victor Stinner2023-08-301-37/+0
| | | | | | | | | | The test was skipped in 2011 by commit 89ba56d5fb1335ef808b87cd33cba95ea141c65d. Scripts in Lib/test/crashers/ do not crash on a reliable way. They rely on undefined behaviors, like state of the stack memory, and so may or may not crash. It is not worth it to make sure that they crash in a continious integration, they should be run manually time to time instead.
* gh-108520: Fix bad fork detection in nested multiprocessing use case (#108568)albanD2023-08-303-3/+34
| | | | | | | | gh-107275 introduced a regression where a SemLock would fail being passed along nested child processes, as the `is_fork_ctx` attribute would be left missing after the first deserialization. --------- Co-authored-by: blurb-it[bot] <43283697+blurb-it[bot]@users.noreply.github.com> Co-authored-by: Antoine Pitrou <pitrou@free.fr>

* gh-108488: Initialize JUMP_BACKWARD cache to 0, not 17 (#108591)Guido van Rossum2023-08-293-3/+6
| | | This mis-initialization caused the executor optimization to kick in sooner than intended. It also set the lower 4 bits of the counter to `1` -- those bits are supposed to be reserved (the actual counter is in the upper 12 bits).
* gh-107557: Remove unnecessary SAVE_IP instructions (#108583)Guido van Rossum2023-08-295-231/+392
| | | | | Also remove NOP instructions. The "stubs" are not optimized in this fashion (their SAVE_IP should always be preserved since it's where to jump next, and they don't contain NOPs by their nature).
