* bpo-38896: Remove PyUnicode_ClearFreeList() function (GH-17354)Victor Stinner2019-11-231-11/+0
| | | | Remove PyUnicode_ClearFreeList() function: the Unicode free list has been removed in Python 3.3.
* bpo-38858: new_interpreter() reuses pycore_init_builtins() (GH-17351)Victor Stinner2019-11-221-1/+0
| | | | | | | | | new_interpreter() now calls _PyBuiltin_Init() to create the builtins module and calls _PyImport_FixupBuiltin(), rather than using _PyImport_FindBuiltin(tstate, "builtins"). pycore_init_builtins() is now responsible to initialize intepr->builtins_copy: inline _PyImport_Init() and remove this function.
* bpo-38858: _PyImport_FixupExtensionObject() handles subinterpreters (GH-17350)Victor Stinner2019-11-222-1/+6
| | | | | If _PyImport_FixupExtensionObject() is called from a subinterpreter, leave extensions unchanged and don't copy the module dictionary into def->m_base.m_copy.
* bpo-38858: Call _PyUnicode_Fini() in Py_EndInterpreter() (GH-17330)Victor Stinner2019-11-221-1/+1
| | | Py_EndInterpreter() now clears the filesystem codec.
* Produce cleaner bytecode for 'with' and 'async with' by generating separate ↵Mark Shannon2019-11-211-6/+2
| | | | | | code for normal and exceptional paths. (#6641) Remove BEGIN_FINALLY, END_FINALLY, CALL_FINALLY and POP_FINALLY bytecodes. Implement finally blocks by code duplication. Reimplement frame.lineno setter using line numbers rather than bytecode offsets.
* bpo-38858: Add _Py_IsMainInterpreter(tstate) (GH-17293)Victor Stinner2019-11-201-0/+2
|
* bpo-37340: Remove PyMethod_ClearFreeList() and PyCFunction_ClearFreeList() ↵Victor Stinner2019-11-203-6/+0
| | | | | | | | (GH-17284) Remove PyMethod_ClearFreeList() and PyCFunction_ClearFreeList() functions: the free lists of bound method objects have been removed. Remove also _PyMethod_Fini() and _PyCFunction_Fini() functions.
* bpo-36854: Move _PyRuntimeState.gc to PyInterpreterState (GH-17287)Victor Stinner2019-11-203-6/+5
| | | | | * Rename _PyGC_InitializeRuntime() to _PyGC_InitState() * finalize_interp_clear() now also calls _PyGC_Fini() in subinterpreters (clear the GC state).
* bpo-38835: Exclude PyFPE macros from the stable API (GH-17228)Victor Stinner2019-11-201-0/+3
| | | | Exclude PyFPE_START_PROTECT() and PyFPE_END_PROTECT() macros of pyfpe.h from Py_LIMITED_API (stable API).
* bpo-36854: gcmodule.c gets its state from tstate (GH-17285)Victor Stinner2019-11-202-5/+7
| | | | | | | | | * Add GCState type for readability * gcmodule.c now gets its gcstate from tstate * _PyGC_DumpShutdownStats() now expects tstate rather than runtime * Rename "state" to "gcstate" for readability: to avoid confusion between "state" and "tstate" for example. * collect() now only expects tstate: it gets gcstate from tstate. * Pass tstate to _PyErr_xxx() functions
* bpo-38858: Factorize Py_EndInterpreter() code (GH-17273)Victor Stinner2019-11-201-2/+2
| | | | | | * Factorize code in common between Py_FinalizeEx() and Py_EndInterpreter(). * Py_EndInterpreter() now also calls _PyWarnings_Fini(). * Call _PyExc_Fini() and _PyGC_Fini() later in the finalization.
* bpo-36710: Add PyInterpreterState.runtime field (GH-17270)Victor Stinner2019-11-202-9/+8
| | | | | | | | | | | Add PyInterpreterState.runtime field: reference to the _PyRuntime global variable. This field exists to not have to pass runtime in addition to tstate to a function. Get runtime from tstate: tstate->interp->runtime. Remove "_PyRuntimeState *runtime" parameter from functions already taking a "PyThreadState *tstate" parameter. _PyGC_Init() first parameter becomes "PyThreadState *tstate".

* | bpo-38631: Avoid Py_FatalError() in handle_legacy_finalizers() (GH-17266)Victor Stinner2019-11-202-1/+2
|/ | | | | * Rename _PyGC_Initialize() to _PyGC_InitializeRuntime() * Add _PyGC_Init(): initialize _PyRuntime.gc.garbage list * Call _PyGC_Init() before _PyTypes_Init()
* bpo-38650: Constify PyStructSequence_UnnamedField. (GH-17005)Serhiy Storchaka2019-11-161-1/+1
| | | | Make it a constant and referring to a constant string.
* bpo-38644: Cleanup ceval.h (GH-17185)Victor Stinner2019-11-162-36/+25
| | | | Move CPython API (Py_LIMITED_API macro not defined) from ceval.h to cpython/ceval.h
* bpo-38644: Add _PyEval_EvalCode() (GH-17183)Victor Stinner2019-11-161-0/+10
| | | _PyFunction_Vectorcall() now pass tstate to function calls.
* bpo-38644: Add _PyObject_Call() (GH-17089)Victor Stinner2019-11-142-10/+46
| | | | | | | | | | * Add pycore_call.h internal header file. * Add _PyObject_Call(): PyObject_Call() with tstate * Add _PyObject_CallNoArgTstate(): _PyObject_CallNoArg() with tstate * Add _PyObject_FastCallDictTstate(): _PyObject_FastCallDict() with tstate * _PyObject_Call_Prepend() now takes tstate * Replace _PyObject_FastCall() calls with _PyObject_VectorcallTstate() calls
* bpo-38644: Add _PyEval_EvalFrame() with tstate (GH-17131)Victor Stinner2019-11-141-0/+9
| | | | Add _PyEval_EvalFrame() static inline function to get eval_frame from tstate->interp.
* bpo-38644: Add _PyObject_VectorcallTstate() (GH-17052)Victor Stinner2019-11-081-4/+14
| | | | | * Add _PyObject_VectorcallTstate() function: similar to _PyObject_Vectorcall(), but with tstate parameter * Add tstate parameter to _PyObject_MakeTpCall()
* bpo-38733: PyErr_Occurred() caller must hold the GIL (GH-17080)Victor Stinner2019-11-071-1/+2
| | | | | | | | | | | bpo-3605, bpo-38733: Optimize _PyErr_Occurred(): remove "tstate == NULL" test. Py_FatalError() no longer calls PyErr_Occurred() if called without holding the GIL. So PyErr_Occurred() no longer has to support tstate==NULL case. _Py_CheckFunctionResult(): use directly _PyErr_Occurred() to avoid explicit "!= NULL" test.
* bpo-36876: Moved Parser/listnode.c statics to interpreter state. (GH-16328)Vinay Sajip2019-11-071-0/+9

* bpo-37645: add new function _PyObject_FunctionStr() (GH-14890)Jeroen Demeyer2019-11-051-0/+1
| | | | | | | | | | | | 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_CheckFunctionResult() (GH-17050)Victor Stinner2019-11-052-4/+14
| | | | | * Add tstate parameter to _Py_CheckFunctionResult() * Add _PyErr_FormatFromCauseTstate() * Replace PyErr_XXX(...) with _PyErr_XXX(state, ...)
* bpo-38644: Pass tstate to Py_EnterRecursiveCall() (GH-16997)Victor Stinner2019-11-041-14/+31
| | | | | | | | | | | | | * 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-38644: Add Py_EnterRecursiveCall() to the limited API (GH-17046)Victor Stinner2019-11-042-35/+58
| | | | | | | | | | Provide Py_EnterRecursiveCall() and Py_LeaveRecursiveCall() as regular functions for the limited API. Previously, there were defined as macros, but these macros didn't work with the limited API which cannot access PyThreadState.recursion_depth field. Remove _Py_CheckRecursionLimit from the stable ABI. Add Include/cpython/ceval.h header file.
* bpo-38600: Change the mark up of NULL in the C API documentation. (GH-16950)Serhiy Storchaka2019-10-301-3/+3
| | | | Replace all *NULL* with ``NULL``.
* bpo-38465: Convert the type of exports counters to Py_ssize_t. (GH-16746)Hai Shi2019-10-211-5/+4

* bpo-38392: Only declare visit_validate() if Py_DEBUG is defined (GH-16689)Victor Stinner2019-10-101-1/+1
| | | | | bpo-38392, bpo-38426: Fix a compiler warning in gcmodule.c. Fix also a typo in PYMEM_DEADBYTE macro comment.
* bpo-36389: Fix _PyBytesWriter in release mode (GH-16624)Victor Stinner2019-10-071-0/+15
| | | | Fix _PyBytesWriter API when Python is built in release mode with assertions.
* bpo-36389: _PyObject_CheckConsistency() available in release mode (GH-16612)Victor Stinner2019-10-074-15/+11
| | | | | | | | | | | | | | | | | | | | | bpo-36389, bpo-38376: The _PyObject_CheckConsistency() function is now also available in release mode. For example, it can be used to debug a crash in the visit_decref() function of the GC. Modify the following functions to also work in release mode: * _PyDict_CheckConsistency() * _PyObject_CheckConsistency() * _PyType_CheckConsistency() * _PyUnicode_CheckConsistency() Other changes: * _PyMem_IsPtrFreed(ptr) now also returns 1 if ptr is NULL (equals to 0). * _PyBytesWriter_CheckConsistency() now returns 1 and is only used with assert(). * Reorder _PyObject_Dump() to write safe fields first, and only attempt to render repr() at the end.
* bpo-38353: getpath.c: allocates strings on the heap (GH-16585)Victor Stinner2019-10-041-3/+2
| | | | | | | | | | | * _Py_FindEnvConfigValue() now returns a string allocated by PyMem_RawMalloc(). * calculate_init() now decodes VPATH macro. * Add calculate_open_pyenv() function. * Add substring() and joinpath2() functions. * Fix add_exe_suffix() And a few cleanup changes.
* bpo-38266: Revert bpo-37878: Make PyThreadState_DeleteCurrent() Internal ↵Joannah Nanjekye2019-10-041-0/+1
| | | | | (GH-16558) Revert the removal of PyThreadState_DeleteCurrent() with documentation.
* bpo-38353: Fix compiler warning in internal headers (GH-16573)Victor Stinner2019-10-043-16/+16
| | | | Replace "_PyRuntimeState" with "struct pyruntimestate" to avoid a warning on typedef re-definition.
* bpo-38353: Fix compiler warning in pycore_initconfig.h (GH-16570)Victor Stinner2019-10-031-2/+2
| | | | Replace "_PyRuntimeState" with "struct pyruntimestate" to avoid a warning on typedef re-definition.
* bpo-38353: Cleanup includes in the internal C API (GH-16548)Victor Stinner2019-10-0212-29/+21
| | | | Use forward declaration of types to avoid includes in the internal C API. Add also comment to justify other includes.
* bpo-38304: PyConfig_InitPythonConfig() cannot fail anymore (GH-16509)Victor Stinner2019-10-012-3/+3
| | | | PyConfig_InitPythonConfig() and PyConfig_InitIsolatedConfig() no longer return PyStatus: they cannot fail anymore.
* bpo-38304: Remove PyConfig.struct_size (GH-16500) (GH-16508)Victor Stinner2019-10-012-12/+4
| | | | | | | For now, we'll rely on the fact that the config structures aren't covered by the stable ABI. We may revisit this in the future if we further explore the idea of offering a stable embedding API. (cherry picked from commit bdace21b769998396d0ccc8da99a8ca9b507bfdf)

* bpo-38317: Fix PyConfig.warnoptions priority (GH-16478)Victor Stinner2019-09-293-3/+6
| | | | | | | | | Fix warnings options priority: PyConfig.warnoptions has the highest priority, as stated in the PEP 587. * Document options order in PyConfig.warnoptions documentation. * Make PyWideStringList_INIT macro private: replace "Py" prefix with "_Py". * test_embed: add test_init_warnoptions().
* bpo-38304: Add PyConfig.struct_size (GH-16451)Victor Stinner2019-09-282-13/+16
| | | | | | | | | | | | | | | | | Add a new struct_size field to PyPreConfig and PyConfig structures to allow to modify these structures in the future without breaking the backward compatibility. * Replace private _config_version field with public struct_size field in PyPreConfig and PyConfig. * Public PyPreConfig_InitIsolatedConfig() and PyPreConfig_InitPythonConfig() return type becomes PyStatus, instead of void. * Internal _PyConfig_InitCompatConfig(), _PyPreConfig_InitCompatConfig(), _PyPreConfig_InitFromConfig(), _PyPreConfig_InitFromPreConfig() return type becomes PyStatus, instead of void. * Remove _Py_CONFIG_VERSION * Update the Initialization Configuration documentation.
* bpo-38234: Py_Initialize() sets global path configuration (GH-16421)Victor Stinner2019-09-261-1/+1
| | | | | | * Py_InitializeFromConfig() now writes PyConfig path configuration to the global path configuration (_Py_path_config). * Add test_embed.test_get_pathconfig(). * Fix typo in _PyWideStringList_Join().
* bpo-38234: Add test_init_setpath_config() to test_embed (GH-16402)Victor Stinner2019-09-261-4/+11
| | | | | | | | | | | | * Add test_embed.test_init_setpath_config(): test Py_SetPath() with PyConfig. * test_init_setpath() and test_init_setpythonhome() no longer call Py_SetProgramName(), but use the default program name. * _PyPathConfig: isolated, site_import and base_executable fields are now only available on Windows. * If executable is set explicitly in the configuration, ignore calculated base_executable: _PyConfig_InitPathConfig() copies executable to base_executable. * Complete path config documentation.

* bpo-38234: Remove _PyPathConfig.dll_path (GH-16307)Victor Stinner2019-09-202-6/+6
| | | | | | | | | The DLL path is not computed from any user configuration and cannot be configured by PyConfig. Instead, add a new _Py_dll_path global variable. Remove _PyConfig_SetPathConfig(): replaced with _PyPathConfig_Init(). Py_Initialize() now longer sets the "global path configuration", but only initialize _Py_dll_path.
