* gh-110525: Add CAPI tests for set and frozenset objects (GH-110526)Nikita Sobolev2023-10-091-0/+3
|
* gh-108867: Add PyThreadState_GetUnchecked() function (#108870)Victor Stinner2023-10-031-2/+2
| | | | | | Add PyThreadState_GetUnchecked() function: similar to PyThreadState_Get(), but don't issue a fatal error if it is NULL. The caller is responsible to check if the result is NULL. Previously, this function was private and known as _PyThreadState_UncheckedGet().
* gh-107073: Make PyObject_VisitManagedDict() public (#108763)Victor Stinner2023-10-021-1/+1
| | | | | | | | Make PyObject_VisitManagedDict() and PyObject_ClearManagedDict() functions public in Python 3.13 C API. * Rename _PyObject_VisitManagedDict() to PyObject_VisitManagedDict(). * Rename _PyObject_ClearManagedDict() to PyObject_ClearManagedDict(). * Document these functions.
* gh-109723: Disable Py_BUILD_CORE in _testcapi (#109727)Victor Stinner2023-09-221-19/+6
| | | | | | | | | | | | | | | | | | Make sure that the internal C API is not tested by mistake by _testcapi. Undefine Py_BUILD_CORE_BUILTIN and Py_BUILD_CORE_MODULE macros in Modules/_testcapi/parts.h: move code from _testcapimodule.c. heaptype_relative.c and vectorcall_limited.c are using the limited C API which is incompatible with the internal C API. Move test_long_numbits() from _testcapi to _testinternalcapi since it uses the internal C API "pycore_long.h". Fix Modules/_testcapi/pyatomic.c: don't include Python.h directly, just include _testcapi/parts.h. Ajust "make check-c-globals" for these changes.
* gh-109496: Detect Py_DECREF() after dealloc in debug mode (#109539)Victor Stinner2023-09-181-0/+21
| | | | | | | | | On a Python built in debug mode, Py_DECREF() now calls _Py_NegativeRefcount() if the object is a dangling pointer to deallocated memory: memory filled with 0xDD "dead byte" by the debug hook on memory allocators. The fix is to check the reference count *before* checking for _Py_IsImmortal(). Add test_decref_freed_object() to test_capi.test_misc.
* GH-91079: Rename C_RECURSION_LIMIT to Py_C_RECURSION_LIMIT (#108507)Victor Stinner2023-09-081-0/+1
| | | | | | | Symbols of the C API should be prefixed by "Py_" to avoid conflict with existing names in 3rd party C extensions on "#include <Python.h>". test.pythoninfo now logs Py_C_RECURSION_LIMIT constant and other _testcapi and _testinternalcapi constants.
* gh-109045: Remove remaining LIMITED_API_AVAILABLE checks in tests (#109046)Anders Kaseorg2023-09-071-6/+0
| | | | | | | | | Commit 13a00078b81776b23b0b6add69b848382240d1f2 (#108663) made all Python builds compatible with the Limited API, and removed the LIMITED_API_AVAILABLE flag. However, some tests were still checking for that flag, so they were now being incorrectly skipped. Remove these checks to let these tests run again. Signed-off-by: Anders Kaseorg <andersk@mit.edu>
* C API tests: use special markers to test that output parameters were set ↵Serhiy Storchaka2023-09-061-4/+10
| | | | (GH-109014)
* gh-108765: Python.h no longer includes <unistd.h> (#108783)Victor Stinner2023-09-021-3/+0
|
* Add Modules/_testcapi/util.h header (GH-108774)Serhiy Storchaka2023-09-011-16/+2
| | | It contains common macros used in C API tests.
* gh-108337: Add pyatomic.h header (#108701)Victor Stinner2023-08-311-0/+3
| | | | | | | | 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-106320: Remove private _PyErr_ChainExceptions() (#108713)Victor Stinner2023-08-311-101/+0
| | | | | | | | | | | | | 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: Remove private _PyDict functions (#108449)Victor Stinner2023-08-241-21/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | Move private functions to the internal C API (pycore_dict.h): * _PyDictView_Intersect() * _PyDictView_New() * _PyDict_ContainsId() * _PyDict_DelItemId() * _PyDict_DelItem_KnownHash() * _PyDict_GetItemIdWithError() * _PyDict_GetItem_KnownHash() * _PyDict_HasSplitTable() * _PyDict_NewPresized() * _PyDict_Next() * _PyDict_Pop() * _PyDict_SetItemId() * _PyDict_SetItem_KnownHash() * _PyDict_SizeOf() No longer export most of these functions. Move also the _PyDictViewObject structure to the internal C API. Move dict_getitem_knownhash() function from _testcapi to the _testinternalcapi extension. Update test_capi.test_dict for this change.
* gh-107178: Remove _testcapi.test_dict_capi() (#108436)Victor Stinner2023-08-241-191/+0
| | | | The new _testcapi.test_dict tests are more complete, _testcapi.test_dict_capi() became redundant.
* gh-106320: Remove private _PyContext_NewHamtForTests() (#108434)Victor Stinner2023-08-241-8/+0
| | | Move the function to the internal C API.
* gh-108216: Cleanup #include in internal header files (#108228)Victor Stinner2023-08-211-3/+3
| | | | | | | | | | | * Add missing includes. * Remove unused includes. * Update old include/symbol names to newer names. * Mention at least one included symbol. * Sort includes. * Update Tools/cases_generator/generate_cases.py used to generated pycore_opcode_metadata.h. * Update Parser/asdl_c.py used to generate pycore_ast.h. * Cleanup also includes in _testcapimodule.c and _testinternalcapi.c.
* gh-107735: Add C API tests for PySys_GetObject() and PySys_SetObject() ↵Serhiy Storchaka2023-08-071-0/+41
| | | | (GH-107736)
* gh-107178: Add the C API tests for the Abstract Objects Layer (GH-107179)Serhiy Storchaka2023-08-071-162/+7
| | | | | | | | | | Cover all the Mapping Protocol, almost all the Sequence Protocol (except PySequence_Fast) and a part of the Object Protocol. Move existing tests to Lib/test/test_capi/test_abstract.py and Modules/_testcapi/abstract.c. Add also tests for PyDict C API.
* gh-106869: Use new PyMemberDef constant names (#106871)Victor Stinner2023-07-251-4/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Remove '#include "structmember.h"'. * If needed, add <stddef.h> to get offsetof() function. * Update Parser/asdl_c.py to regenerate Python/Python-ast.c. * Replace: * T_SHORT => Py_T_SHORT * T_INT => Py_T_INT * T_LONG => Py_T_LONG * T_FLOAT => Py_T_FLOAT * T_DOUBLE => Py_T_DOUBLE * T_STRING => Py_T_STRING * T_OBJECT => _Py_T_OBJECT * T_CHAR => Py_T_CHAR * T_BYTE => Py_T_BYTE * T_UBYTE => Py_T_UBYTE * T_USHORT => Py_T_USHORT * T_UINT => Py_T_UINT * T_ULONG => Py_T_ULONG * T_STRING_INPLACE => Py_T_STRING_INPLACE * T_BOOL => Py_T_BOOL * T_OBJECT_EX => Py_T_OBJECT_EX * T_LONGLONG => Py_T_LONGLONG * T_ULONGLONG => Py_T_ULONGLONG * T_PYSSIZET => Py_T_PYSSIZET * T_NONE => _Py_T_NONE * READONLY => Py_READONLY * PY_AUDIT_READ => Py_AUDIT_READ * READ_RESTRICTED => Py_AUDIT_READ * PY_WRITE_RESTRICTED => _Py_WRITE_RESTRICTED * RESTRICTED => (READ_RESTRICTED | _Py_WRITE_RESTRICTED)
* gh-106004: Add PyDict_GetItemRef() function (#106005)Victor Stinner2023-07-211-0/+191
| | | | | * Add PyDict_GetItemRef() and PyDict_GetItemStringRef() functions. Add these functions to the stable ABI version 3.13. * Add unit tests on the PyDict C API in test_capi.
* gh-105227: Add PyType_GetDict() (GH-105747)Eric Snow2023-07-101-0/+25
| | | | | This compensates for static builtin types having `tp_dict` set to `NULL`. Co-authored-by: Petr Viktorin <encukou@gmail.com>
* gh-105927: PyWeakref_GetRef() returns 1 on success (#106561)Victor Stinner2023-07-091-1/+1
| | | | | | PyWeakref_GetRef() now returns 1 on success, and return 0 if the reference is dead. Co-authored-by: Serhiy Storchaka <storchaka@gmail.com>
* gh-106320: Remove private pylifecycle.h functions (#106400)Victor Stinner2023-07-041-32/+0
| | | | | | | Remove private pylifecycle.h functions: move them to the internal C API ( pycore_atexit.h, pycore_pylifecycle.h and pycore_signal.h). No longer export most of these functions. Move _testcapi.test_atexit() to _testinternalcapi.
* gh-106320: Remove private _PyImport C API functions (#106383)Victor Stinner2023-07-031-2/+8
| | | | | | * Remove private _PyImport C API functions: move them to the internal C API (pycore_import.h). * No longer export most of these private functions. * _testcapi avoids private _PyImport_GetModuleAttrString().
* gh-104922: remove PY_SSIZE_T_CLEAN (#106315)Inada Naoki2023-07-021-2/+0
|
* gh-106320: Remove private _PyInterpreterState functions (#106325)Victor Stinner2023-07-021-5/+0
| | | | | | | | | Remove private _PyThreadState and _PyInterpreterState C API functions: move them to the internal C API (pycore_pystate.h and pycore_interp.h). Don't export most of these functions anymore, but still export functions used by tests. Remove _PyThreadState_Prealloc() and _PyThreadState_Init() from the C API, but keep it in the stable API.
* gh-106316: Remove pytime.h header file (#106317)Victor Stinner2023-07-011-3/+0
| | | | | | | | | | | | | | | | | Remove the "cpython/pytime.h" header file: it only contained private functions. Move functions to the internal pycore_time.h header file. Move tests from _testcapi to _testinternalcapi. Rename also test methods to have the same name than tested C functions. No longer export these functions: * _PyTime_Add() * _PyTime_As100Nanoseconds() * _PyTime_FromMicrosecondsClamp() * _PyTime_FromTimespec() * _PyTime_FromTimeval() * _PyTime_GetPerfCounterWithInfo() * _PyTime_MulDiv()
* gh-105927: Deprecate PyWeakref_GetObject() function (#106006)Victor Stinner2023-06-261-0/+6
| | | Deprecate PyWeakref_GetObject() and PyWeakref_GET_OBJECT() functions.
* gh-105927: Fix test_weakref_capi() refleak (#105966)Victor Stinner2023-06-211-16/+32
| | | Test PyWeakref_GetRef(NULL) and PyWeakref_GetObject(NULL).
* gh-105927: Add PyWeakref_GetRef() function (#105932)Victor Stinner2023-06-211-0/+79
| | | | Add tests on PyWeakref_NewRef(), PyWeakref_GetObject(), PyWeakref_GET_OBJECT() and PyWeakref_GetRef().
* gh-105922: Add PyImport_AddModuleRef() function (#105923)Victor Stinner2023-06-201-0/+48
| | | | | | * Add tests on PyImport_AddModuleRef(), PyImport_AddModule() and PyImport_AddModuleObject(). * pythonrun.c: Replace Py_XNewRef(PyImport_AddModule(name)) with PyImport_AddModuleRef(name).
* gh-105603: Change the PyInterpreterConfig.own gil Field (gh-105620)Eric Snow2023-06-131-7/+7
| | | We are changing it to be more flexible that a strict bool can be for possible future expanded used cases.
* gh-104614: Fix potential ref. leak in ↵Erlend E. Aasland2023-06-021-1/+3
| | | | _testcapimodule/get_basic_static_type() (#105225)
* gh-104614: Make Sure ob_type is Always Set Correctly by PyType_Ready() ↵Eric Snow2023-06-011-0/+45
| | | | | | | (gh-105122) When I added the relevant condition to type_ready_set_bases() in gh-103912, I had missed that the function also sets tp_base and ob_type (if necessary). That led to problems for third-party static types. We fix that here, by making those extra operations distinct and by adjusting the condition to be more specific.
* gh-105107: Remove PyCFunction_Call() function (#105181)Victor Stinner2023-06-011-0/+14
| | | | | * Keep the function in the stable ABI. * Add unit tests on PyCFunction_Call() since it remains supported in the stable ABI.
* gh-104922: Make `PY_SSIZE_T_CLEAN` not mandatory again (#105051)Inada Naoki2023-05-311-47/+0
|
* gh-105020: Share tp_bases and tp_mro Between Interpreters For All Static ↵Eric Snow2023-05-311-0/+23
| | | | | Builtin Types (gh-105115) In gh-103912 we added tp_bases and tp_mro to each PyInterpreterState.types.builtins entry. However, doing so ignored the fact that both PyTypeObject fields are public API, and not documented as internal (as opposed to tp_subclasses). We address that here by reverting back to shared objects, making them immortal in the process.
* gh-104645: fix error handling in marshal tests (#104646)Irit Katriel2023-05-191-18/+14

* GH-102818: Do not call `PyTraceBack_Here` in sys.settrace trampoline. ↵Mark Shannon2023-05-191-0/+28

* gh-93649: Split gc- and allocation tests from _testcapimodule.c (GH-104403)Jurica Bradarić2023-05-121-326/+3
|
* gh-99113: Add PyInterpreterConfig.own_gil (gh-104204)Eric Snow2023-05-051-2/+10
| | | | | We also add PyInterpreterState.ceval.own_gil to record if the interpreter actually has its own GIL. Note that for now we don't actually respect own_gil; all interpreters still share the one GIL. However, PyInterpreterState.ceval.own_gil does reflect PyInterpreterConfig.own_gil. That lie is a temporary one that we will fix when the GIL really becomes per-interpreter.
* gh-104190: fix ubsan crash (#104191)sunmy20192023-05-051-1/+1

* gh-103509: PEP 697 -- Limited C API for Extending Opaque Types (GH-103511)Petr Viktorin2023-05-041-0/+3
| | | | Co-authored-by: Oleg Iarygin <oleg@arhadthedev.net> Co-authored-by: Erlend E. Aasland <erlend.aasland@protonmail.com>
* gh-104109: Expose Py_NewInterpreterFromConfig() in the Public C-API (gh-104110)Eric Snow2023-05-031-2/+2
| | | | | We also expose PyInterpreterConfig. This is part of the PEP 684 (per-interpreter GIL) implementation. We will add docs as soon as we can. FYI, I'm adding the new config field for per-interpreter GIL in gh-99114.

* gh-101659: Isolate "obmalloc" State to Each Interpreter (gh-101660)Eric Snow2023-04-241-2/+10
| | | | | | | | | | | | | | This is strictly about moving the "obmalloc" runtime state from `_PyRuntimeState` to `PyInterpreterState`. Doing so improves isolation between interpreters, specifically most of the memory (incl. objects) allocated for each interpreter's use. This is important for a per-interpreter GIL, but such isolation is valuable even without it. FWIW, a per-interpreter obmalloc is the proverbial canary-in-the-coalmine when it comes to the isolation of objects between interpreters. Any object that leaks (unintentionally) to another interpreter is highly likely to cause a crash (on debug builds at least). That's a useful thing to know, relative to interpreter isolation.
