* bpo-36379: __ipow__ must be a ternaryfunc, not a binaryfunc (GH-13546)Zackery Spytz2019-05-311-0/+2
| | | | | | | If a type's __ipow__ method was implemented in C, attempting to use the *modulo* parameter would cause crashes. https://bugs.python.org/issue36379

* bpo-36763: Implement the PEP 587 (GH-13592)Victor Stinner2019-05-271-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Add a whole new documentation page: "Python Initialization Configuration" * PyWideStringList_Append() return type is now PyStatus, instead of int * PyInterpreterState_New() now calls PyConfig_Clear() if PyConfig_InitPythonConfig() fails. * Rename files: * Python/coreconfig.c => Python/initconfig.c * Include/cpython/coreconfig.h => Include/cpython/initconfig.h * Include/internal/: pycore_coreconfig.h => pycore_initconfig.h * Rename structures * _PyCoreConfig => PyConfig * _PyPreConfig => PyPreConfig * _PyInitError => PyStatus * _PyWstrList => PyWideStringList * Rename PyConfig fields: * use_module_search_paths => module_search_paths_set * module_search_path_env => pythonpath_env * Rename PyStatus field: _func => func * PyInterpreterState: rename core_config field to config * Rename macros and functions: * _PyCoreConfig_SetArgv() => PyConfig_SetBytesArgv() * _PyCoreConfig_SetWideArgv() => PyConfig_SetArgv() * _PyCoreConfig_DecodeLocale() => PyConfig_SetBytesString() * _PyInitError_Failed() => PyStatus_Exception() * _Py_INIT_ERROR_TYPE_xxx enums => _PyStatus_TYPE_xxx * _Py_UnixMain() => Py_BytesMain() * _Py_ExitInitError() => Py_ExitStatusException() * _Py_PreInitializeFromArgs() => Py_PreInitializeFromBytesArgs() * _Py_PreInitializeFromWideArgs() => Py_PreInitializeFromArgs() * _Py_PreInitialize() => Py_PreInitialize() * _Py_RunMain() => Py_RunMain() * _Py_InitializeFromConfig() => Py_InitializeFromConfig() * _Py_INIT_XXX() => _PyStatus_XXX() * _Py_INIT_FAILED() => _PyStatus_EXCEPTION() * Rename 'err' PyStatus variables to 'status' * Convert RUN_CODE() macro to config_run_code() static inline function * Remove functions: * _Py_InitializeFromArgs() * _Py_InitializeFromWideArgs() * _PyInterpreterState_GetCoreConfig()
* bpo-37017: PyObject_CallMethodObjArgs uses LOAD_METHOD optimization (GH-13516)Michael J. Sullivan2019-05-261-0/+4
| | | | | | | | | Update PyObject_CallMethodObjArgs and _PyObject_CallMethodIdObjArgs to use _PyObject_GetMethod to avoid creating a bound method object in many cases. On a microbenchmark of PyObject_CallMethodObjArgs calling a method on an interpreted Python class, this optimization resulted in a 1.7x speedup.
* bpo-36763: _Py_RunMain() doesn't call Py_Exit() anymore (GH-13390)Victor Stinner2019-05-171-0/+3
| | | | | | | | | Py_Main() and _Py_RunMain() now return the exitcode rather than calling Py_Exit(exitcode) when calling PyErr_Print() if the current exception type is SystemExit. * Add _Py_HandleSystemExit(). * Add pymain_exit_err_print(). * Add pymain_exit_print().
* bpo-36728: Remove PyEval_ReInitThreads() from C API (GH-13241)Victor Stinner2019-05-131-0/+2
| | | | | | | | Remove the PyEval_ReInitThreads() function from the Python C API. It should not be called explicitly: use PyOS_AfterFork_Child() instead. Rename PyEval_ReInitThreads() to _PyEval_ReInitThreads() and add a 'runtime' parameter.

* bpo-36763: Fix Py_SetStandardStreamEncoding() (GH-13028)Victor Stinner2019-04-301-0/+2
| | | | Fix memory leak in Py_SetStandardStreamEncoding(): release memory if the function is called twice.
* bpo-36025: Fix PyDate_FromTimestamp API (GH-11922)Paul Ganssle2019-04-271-0/+5
| | | | | | | | | | | | | In the process of converting the date.fromtimestamp function to use argument clinic in GH-8535, the C API for PyDate_FromTimestamp was inadvertently changed to expect a timestamp object rather than an argument tuple. This PR fixes this backwards-incompatible change by adding a new wrapper function for the C API function that unwraps the argument tuple and passes it to the underlying function. This PR also adds tests for both PyDate_FromTimestamp and PyDateTime_FromTimestamp to prevent any further regressions.
* bpo-36641: Add "const" to PyDoc_VAR macro (GH-12854)Inada Naoki2019-04-161-0/+2
| | | It reduces "data" segment in python about 200KB.
* bpo-36389: Change PyMem_SetupDebugHooks() constants (GH-12782)Victor Stinner2019-04-111-0/+5
| | | | | Modify CLEANBYTE, DEADDYTE and FORBIDDENBYTE constants: use 0xCD, 0xDD and 0xFD, rather than 0xCB, 0xBB and 0xFB, to use the same byte patterns than Windows CRT debug malloc() and free().
* bpo-36443: Disable C locale coercion and UTF-8 Mode by default (GH-12589)Victor Stinner2019-03-271-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | bpo-36443, bpo-36202: Since Python 3.7.0, calling Py_DecodeLocale() before Py_Initialize() produces mojibake if the LC_CTYPE locale is coerced and/or if the UTF-8 Mode is enabled by the user configuration. This change fix the issue by disabling LC_CTYPE coercion and UTF-8 Mode by default. They must now be enabled explicitly (opt-in) using the new _Py_PreInitialize() API with _PyPreConfig. When embedding Python, set coerce_c_locale and utf8_mode attributes of _PyPreConfig to -1 to enable automatically these parameters depending on the LC_CTYPE locale, environment variables and command line arguments Alternative: Setting Py_UTF8Mode to 1 always explicitly enables the UTF-8 Mode. Changes: * _PyPreConfig_INIT now sets coerce_c_locale and utf8_mode to 0 by default. * _Py_InitializeFromArgs() and _Py_InitializeFromWideArgs() can now be called with config=NULL.
* bpo-35810: Incref heap-allocated types in PyObject_Init (GH-11661)Eddie Elizondo2019-03-271-0/+4
| | | | | * Incref heap-allocated types in PyObject_Init * Add documentation and porting notes to What's New

* bpo-36381: warn when no PY_SSIZE_T_CLEAN defined (GH-12473)Inada Naoki2019-03-231-0/+2
| | | We will remove int support from 3.10 or 4.0.
* bpo-36142: Exclude coreconfig.h from Py_LIMITED_API (GH-12111)Victor Stinner2019-03-011-0/+2
| | | | | | | | | The whole coreconfig.h header is now excluded from Py_LIMITED_API. Move functions definitions into a new internal pycore_coreconfig.h header. * Move Include/coreconfig.h to Include/cpython/coreconfig.h * coreconfig.h header is now excluded from Py_LIMITED_API * Move functions to pycore_coreconfig.h

* bpo-35713: Rework Python initialization (GH-11647)Victor Stinner2019-01-221-0/+3
| | | | | | | | | | | | | | | | | | | * The PyByteArray_Init() and PyByteArray_Fini() functions have been removed. They did nothing since Python 2.7.4 and Python 3.2.0, were excluded from the limited API (stable ABI), and were not documented. * Move "_PyXXX_Init()" and "_PyXXX_Fini()" declarations from Include/cpython/pylifecycle.h to Include/internal/pycore_pylifecycle.h. Replace "PyAPI_FUNC(TYPE)" with "extern TYPE". * _PyExc_Init() now returns an error on failure rather than calling Py_FatalError(). Move macros inside _PyExc_Init() and undefine them when done. Rewrite macros to make them look more like statement: add ";" when using them, add "do { ... } while (0)". * _PyUnicode_Init() now returns a _PyInitError error rather than call Py_FatalError(). * Move stdin check from _PySys_BeginInit() to init_sys_streams(). * _Py_ReadyTypes() now returns a _PyInitError error rather than calling Py_FatalError().
* bpo-33817: Fix _PyBytes_Resize() for empty bytes object. (GH-11516)Serhiy Storchaka2019-01-121-0/+1

* bpo-34523, bpo-35322: Fix unicode_encode_locale() (GH-10759)Victor Stinner2018-11-281-0/+2
| | | | | | | | | Fix memory leak in PyUnicode_EncodeLocale() and PyUnicode_EncodeFSDefault() on error handling. Changes: * Fix unicode_encode_locale() error handling * Fix test_codecs.LocaleCodecTest
* bpo-35134: Create Include/cpython/ subdirectory (GH-10624)Victor Stinner2018-11-231-0/+1
| | | | | | | | | | | | | | | | Include/*.h should be the "portable Python API", whereas Include/cpython/*.h should be the "CPython API": CPython implementation details. Changes: * Create Include/cpython/ subdirectory * "make install" now creates $prefix/include/cpython and copy Include/cpython/* to $prefix/include/cpython * Create Include/cpython/objimpl.h: move objimpl.h code surrounded by "#ifndef Py_LIMITED_API" to cpython/objimpl.h. * objimpl.h now includes cpython/objimpl.h * Windows installer (MSI) now also install Include/ subdirectories: Include/cpython/ and Include/internal/.
* bpo-35296: make install now installs the internal API (GH-10665)Victor Stinner2018-11-231-0/+2
| | | | make install now also installs the internal API: Include/internal/*.h header files.

* bpo-34589: C locale coercion off by default (GH-9073)Victor Stinner2018-09-171-0/+3
| | | | | | | | | Py_Initialize() and Py_Main() cannot enable the C locale coercion (PEP 538) anymore: it is always disabled. It can now only be enabled by the Python program ("python3). test_embed: get_filesystem_encoding() doesn't have to set PYTHONUTF8 nor PYTHONCOERCECLOCALE, these variables are already set in the parent.
* Revert "bpo-34595: Add %T format to PyUnicode_FromFormatV() (GH-9080)" (GH-9187)Victor Stinner2018-09-111-4/+0

* bpo-34595: Add %T format to PyUnicode_FromFormatV() (GH-9080)Victor Stinner2018-09-071-0/+4
| | | | | | | | | * Add %T format to PyUnicode_FromFormatV(), and so to PyUnicode_FromFormat() and PyErr_Format(), to format an object type name: equivalent to "%s" with Py_TYPE(obj)->tp_name. * Replace Py_TYPE(obj)->tp_name with %T format in unicodeobject.c. * Add unit test on %T format. * Rename unicode_fromformat_write_cstr() to unicode_fromformat_write_utf8(), to make the intent more explicit.
* bpo-34523: Py_DecodeLocale() use UTF-8 on Windows (GH-8998)Victor Stinner2018-08-291-0/+2
| | | | | | | Py_DecodeLocale() and Py_EncodeLocale() now use the UTF-8 encoding on Windows if Py_LegacyWindowsFSEncodingFlag is zero. pymain_read_conf() now sets Py_LegacyWindowsFSEncodingFlag in its loop, but restore its value at exit.
