* bpo-38858: new_interpreter() reuses _PySys_Create() (GH-17481)Victor Stinner2019-12-061-1/+0
| | | | | | | new_interpreter() now calls _PySys_Create() to create a new sys module isolated from the main interpreter. It now calls _PySys_InitCore() and _PyImport_FixupBuiltin(). init_interp_main() now calls _PySys_InitMain().
* 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 Stinner2019-11-221-0/+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.
* bpo-38858: Add _Py_IsMainInterpreter(tstate) (GH-17293)Victor Stinner2019-11-201-0/+2
|
* bpo-37340: Remove PyMethod_ClearFreeList() and PyCFunction_ClearFreeList() ↵Victor Stinner2019-11-201-2/+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-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-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 Stinner2019-11-141-0/+39
| | | | | | | | | | * 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-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-38644: Pass tstate to _Py_CheckFunctionResult() (GH-17050)Victor Stinner2019-11-051-0/+6

* 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 Stinner2019-10-072-5/+7
| | | | | | | | | | | | | | | | | | | | | 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.

| | | | 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 Stinner2019-10-011-1/+1
| | | | PyConfig_InitPythonConfig() and PyConfig_InitIsolatedConfig() no longer return PyStatus: they cannot fail anymore.
* bpo-38304: Remove PyConfig.struct_size (GH-16500) (GH-16508)Victor Stinner2019-10-011-2/+2
| | | | | | | 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 Stinner2019-09-292-2/+2

* bpo-38304: Add PyConfig.struct_size (GH-16451)Victor Stinner2019-09-281-6/+6
| | | | | | | | | | | | | | | | | 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-38236: Dump path config at first import error (GH-16300)Victor Stinner2019-09-231-0/+1
| | | | Python now dumps path configuration if it fails to import the Python codecs of the filesystem and stdio encodings.
* 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.
* Fix _PyTraceMalloc_Fini() definition (GH-16259)Victor Stinner2019-09-181-1/+1
| | | The function return type is void, not int.
* bpo-38070: Add _PyRuntimeState.preinitializing (GH-16245)Victor Stinner2019-09-171-3/+8
| | | | | | Add _PyRuntimeState.preinitializing field: set to 1 while Py_PreInitialize() is running. _PyRuntimeState: rename also pre_initialized field to preinitialized.

| | | | Declare Py_BytesMain() in Include/pylifecycle.h, rather in Include/internal/pycore_pylifecycle.h.
* Make PyXXX_Fini() functions private (GH-15531)Victor Stinner2019-08-261-12/+13
| | | | | For example, rename PyTuple_Fini() to _PyTuple_Fini(). These functions are only declared in the internal C API.
* bpo-36763: PyConfig_Read() handles PySys_AddXOption() (GH-15431)Victor Stinner2019-08-231-0/+2
| | | | | | | | | | PyConfig_Read() is now responsible to handle early calls to PySys_AddXOption() and PySys_AddWarnOption(). Options added by PySys_AddXOption() are now handled the same way than PyConfig.xoptions and command line -X options. For example, PySys_AddXOption(L"faulthandler") enables faulthandler as expected.
* bpo-37369: Fix initialization of sys members when launched via an app ↵Steve Dower2019-06-291-0/+2
