* bpo-38644: Add _PyObject_Call() (GH-17089)Victor Stinner2019-11-141-10/+7
| | | | | | | | | | * 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 _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-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 Stinner2019-11-051-4/+8
| | | | | * 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 Stinner2019-11-041-0/+50
| | | | | | | | | | 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-36389: _PyObject_CheckConsistency() available in release mode (GH-16612)Victor Stinner2019-10-071-0/+4
| | | | | | | | | | | | | | | | | | | | | 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-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-38304: PyConfig_InitPythonConfig() cannot fail anymore (GH-16509)Victor Stinner2019-10-011-2/+2
| | | | PyConfig_InitPythonConfig() and PyConfig_InitIsolatedConfig() no longer return PyStatus: they cannot fail anymore.
* bpo-38304: Remove PyConfig.struct_size (GH-16500) (GH-16508)Victor Stinner2019-10-011-10/+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 Stinner2019-09-291-1/+4
| | | | | | | | | 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 Stinner2019-09-281-7/+10
| | | | | | | | | | | | | | | | | 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-38005: Fixed comparing and creating of InterpreterID and ChannelID. ↵Serhiy Storchaka2019-09-131-2/+0
| | | | | | | | | | | | | (GH-15652) * Fix a crash in comparing with float (and maybe other crashes). * They are now never equal to strings and non-integer numbers. * Comparison with a large number no longer raises OverflowError. * Arbitrary exceptions no longer silenced in constructors and comparisons. * TypeError raised in the constructor contains now the name of the type. * Accept only ChannelID and int-like objects in channel functions. * Accept only InterpreterId, int-like objects and str in the InterpreterId constructor. * Accept int-like objects, not just int in interpreter related functions.
* bpo-36763: Implement PyWideStringList_Insert() of PEP 587 (GH-15423)Victor Stinner2019-08-231-0/+3

* Unmark files as executable that can't actually be executed. (GH-15353)Greg Price2019-08-211-0/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | There are plenty of legitimate scripts in the tree that begin with a `#!`, but also a few that seem to be marked executable by mistake. Found them with this command -- it gets executable files known to Git, filters to the ones that don't start with a `#!`, and then unmarks them as executable: $ git ls-files --stage \ | perl -lane 'print $F[3] if (!/^100644/)' \ | while read f; do head -c2 "$f" | grep -qxF '#!' \ || chmod a-x "$f"; \ done Looking at the list by hand confirms that we didn't sweep up any files that should have the executable bit after all. In particular * The `.psd` files are images from Photoshop. * The `.bat` files sure look like things that can be run. But we have lots of other `.bat` files, and they don't have this bit set, so it must not be needed for them. Automerge-Triggered-By: @benjaminp
* bpo-15913: Implement PyBuffer_SizeFromFormat() (GH-13873)Joannah Nanjekye2019-08-201-1/+1

* bpo-37540: vectorcall: keyword names must be strings (GH-14682)Jeroen Demeyer2019-08-161-2/+1
| | | | | | | | The fact that keyword names are strings is now part of the vectorcall and `METH_FASTCALL` protocols. The biggest concrete change is that `_PyStack_UnpackDict` now checks that and raises `TypeError` if not. CC @markshannon @vstinner https://bugs.python.org/issue37540

* bpo-36710: Add tstate parameter in import.c (GH-14218)Victor Stinner2019-06-192-9/+1
| | | | | | | | | | | | | * Add 'tstate' parameter to many internal import.c functions. * _PyImportZip_Init() now gets 'tstate' parameter rather than 'interp'. * Add 'interp' parameter to _PyState_ClearModules() and rename it to _PyInterpreterState_ClearModules(). * Move private _PyImport_FindBuiltin() to the internal C API; add 'tstate' parameter to it. * Remove private _PyImport_AddModuleObject() from the C API: use public PyImport_AddModuleObject() instead. * Remove private _PyImport_FindExtensionObjectEx() from the C API: use private _PyImport_FindExtensionObject() instead.
* bpo-35134: Add Include/cpython/import.h header file (GH-14213)Victor Stinner2019-06-181-0/+57
| | | | | | * Add Include/cpython/import.h and Include/internal/pycore_import.h header files. * Move _PyImport_ReInitLock() to the internal C API. Don't export the symbol anymore.
* bpo-37194: Add a new public PyObject_CallNoArgs() function (GH-13890)Victor Stinner2019-06-171-1/+3
| | | | | | | | | | | | | | | Add a new public PyObject_CallNoArgs() function to the C API: call a callable Python object without any arguments. It is the most efficient way to call a callback without any argument. On x86-64, for example, PyObject_CallFunctionObjArgs(func, NULL) allocates 960 bytes on the stack per call, whereas PyObject_CallNoArgs(func) only allocates 624 bytes per call. It is excluded from stable ABI 3.8. Replace private _PyObject_CallNoArg() with public PyObject_CallNoArgs() in C extensions: _asyncio, _datetime, _elementtree, _pickle, _tkinter and readline.

| | | | | | | | | | | | | | | | | | | * _PyPreConfig_GetGlobalConfig() and _PyCoreConfig_GetGlobalConfig() now do nothing if the configuration was not initialized with _PyPreConfig_InitCompatConfig() and _PyCoreConfig_InitCompatConfig() * Remove utf8_mode=-2 special case: use utf8_mode=-1 instead. * Fix _PyPreConfig_InitPythonConfig(): * isolated = 0 instead of -1 * use_environment = 1 instead of -1 * Rename _PyConfig_INIT to _PyConfig_INIT_COMPAT * Rename _PyPreConfig_Init() to _PyPreConfig_InitCompatConfig() * Rename _PyCoreConfig_Init() to _PyCoreConfig_InitCompatConfig() * PyInterpreterState_New() now uses _PyCoreConfig_InitPythonConfig() as default configuration, but it's very quickly overriden anyway. * _freeze_importlib.c uses _PyCoreConfig_SetString() to set program_name. * Cleanup preconfig_init_utf8_mode(): cmdline is always non-NULL.
* bpo-36763: Fix _PyRuntime.preconfig.coerce_c_locale (GH-13444)Victor Stinner2019-05-201-2/+2
| | | | | | | | | | | _PyRuntime.preconfig.coerce_c_locale can now be used to check if the C locale has been coerced. * Fix _Py_LegacyLocaleDetected(): don't attempt to coerce the C locale if LC_ALL environment variable is set. Add 'warn' parameter: emit_stderr_warning_for_legacy_locale() must not the LC_ALL env var. * _PyPreConfig_Write() sets coerce_c_locale to 0 if _Py_CoerceLegacyLocale() fails.
* bpo-36763: Fix Python preinitialization (GH-13432)Victor Stinner2019-05-202-6/+20

| | | | | | | | | | | | | | | | | _PyPreConfig_InitPythonConfig() and _PyCoreConfig_InitPythonConfig() no longer inherit their values from global configuration variables. Changes: * _PyPreCmdline_Read() now ignores -X dev and PYTHONDEVMODE if dev_mode is already set. * Inline _PyPreConfig_INIT macro into _PyPreConfig_Init() function. * Inline _PyCoreConfig_INIT macro into _PyCoreConfig_Init() function. * Replace _PyCoreConfig_Init() with _PyCoreConfig_InitPythonConfig() in most tests of _testembed.c. * Replace _PyCoreConfig_Init() with _PyCoreConfig_InitIsolatedConfig() in _freeze_importlib.c. * Move some initialization functions from the internal to the private API.
* bpo-36763: _Py_InitializeFromArgs() argc becomes Py_ssize_t (GH-13396)Victor Stinner2019-05-171-4/+4
| | | | | | | * The type of initlization function 'argc' parameters becomes Py_ssize_t, instead of int. * Change _PyPreConfig_Copy() return type to void, instead of int. The function cannot fail anymore. * Fix compilation warnings on Windows.
* bpo-36763: Add _PyInitError functions (GH-13395)Victor Stinner2019-05-171-30/+7
| | | | | | | | | | | | | | | * Add _PyInitError functions: * _PyInitError_Ok() * _PyInitError_Error() * _PyInitError_NoMemory() * _PyInitError_Exit() * _PyInitError_IsError() * _PyInitError_IsExit() * _PyInitError_Failed() * frozenmain.c and _testembed.c now use functions rather than macros. * Move _Py_INIT_xxx() macros to the internal API. * Move _PyWstrList_INIT macro to the internal API.
* bpo-36945: Add _PyPreConfig.configure_locale (GH-13368)Victor Stinner2019-05-171-0/+5
| | | | | _PyPreConfig_InitIsolatedConfig() sets configure_locale to 0 to prevent Python to modify the LC_CTYPE locale. In that case, coerce_c_locale an coerce_c_locale_warn are set to 0 as well.
