* bpo-39489: Remove COUNT_ALLOCS special build (GH-18259)Victor Stinner2020-02-031-15/+0
| | | | | | | | | | | Remove: * COUNT_ALLOCS macro * sys.getcounts() function * SHOW_ALLOC_COUNT code in listobject.c * SHOW_TRACK_COUNT code in tupleobject.c * PyConfig.show_alloc_count field * -X showalloccount command line option * @test.support.requires_type_collecting decorator
* bpo-38960: DTrace build fix for FreeBSD. (GH-17451)David Carlier2020-01-281-1/+1
| | | | | | | | DTrace build fix for FreeBSD. - allowing passing an extra flag as it need to define the arch size. - casting some probe's arguments.
* bpo-39008: Require Py_ssize_t for PySys_Audit formats rather than raise a ↵Steve Dower2019-12-091-1/+1
| | | | deprecation warning (GH-17540)
* bpo-38858: new_interpreter() reuses _PySys_Create() (GH-17481)Victor Stinner2019-12-061-5/+14
| | | | | | | 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-38920: Add audit hooks for when sys.excepthook and sys.unraisable hooks ↵Steve Dower2019-11-281-2/+2
| | | | | are invoked (GH-17392) Also fixes some potential segfaults in unraisable hook handling.
* bpo-36710: Add PyInterpreterState.runtime field (GH-17270)Victor Stinner2019-11-201-15/+14
| | | | | | | | | | | 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-38317: Fix PyConfig.warnoptions priority (GH-16478)Victor Stinner2019-09-291-2/+2
| | | | | | | | | 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-37206: Unrepresentable default values no longer represented as None. ↵Serhiy Storchaka2019-09-141-2/+2
| | | | | | | (GH-13933) In ArgumentClinic, value "NULL" should now be used only for unrepresentable default values (like in the optional third parameter of getattr). "None" should be used if None is accepted as argument and passing None has the same effect as not passing the argument at all.
* bpo-38096: Clean up the "struct sequence" / "named tuple" docs (GH-15895)Raymond Hettinger2019-09-111-6/+6
| | | | | | | | * bpo-38096: Clean up the "struct sequence" / "named tuple" docs * Fix remaining occurrences of "struct sequence" * Repair a user visible docstring
* bpo-37994: Fix silencing all errors if an attribute lookup fails. (GH-15630)Serhiy Storchaka2019-09-011-8/+6
| | | Only AttributeError should be silenced.
* bpo-36763: PyConfig_Read() handles PySys_AddXOption() (GH-15431)Victor Stinner2019-08-231-29/+29
| | | | | | | | | | 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-37926: Fix PySys_SetArgvEx(0, NULL, 0) crash (GH-15415)Victor Stinner2019-08-231-1/+1
| | | | | | | | | | empty_argv is no longer static in Python 3.8, but it is declared in a temporary scope, whereas argv keeps a reference to it. empty_argv memory (allocated on the stack) is reused by make_sys_argv() code which is inlined when using gcc -O3. Define empty_argv in PySys_SetArgvEx() body, to ensure that it remains valid for the whole lifetime of the PySys_SetArgvEx() call.
* Fix typos in comments, docs and test names (#15018)Min ho Kim2019-07-301-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | * Fix typos in comments, docs and test names * Update test_pyparse.py account for change in string length * Apply suggestion: splitable -> splittable Co-Authored-By: Terry Jan Reedy <tjreedy@udel.edu> * Apply suggestion: splitable -> splittable Co-Authored-By: Terry Jan Reedy <tjreedy@udel.edu> * Apply suggestion: Dealloccte -> Deallocate Co-Authored-By: Terry Jan Reedy <tjreedy@udel.edu> * Update posixmodule checksum. * Reverse idlelib changes.
* bpo-37547: add _PyObject_CallMethodOneArg (GH-14685)Jeroen Demeyer2019-07-111-4/+2
|
* bpo-37369: Fix initialization of sys members when launched via an app ↵Steve Dower2019-06-291-0/+1
| | | | | | | container (GH-14428) sys._base_executable is now always defined on all platforms, and can be overridden through configuration. Also adds test.support.PythonSymlink to encapsulate platform-specific logic for symlinking sys.executable
* bpo-37337: Add _PyObject_VectorcallMethod() (GH-14228)Jeroen Demeyer2019-06-281-20/+7
|
* bpo-37414: Remove sys.callstats() (GH-14398)Victor Stinner2019-06-261-39/+0
| | | | | Remove the undocumented sys.callstats() function. Since Python 3.7, it was deprecated and always returned None. It required a special build option CALL_PROFILE which was already removed in Python 3.7.
* bpo-37392: Remove sys.setcheckinterval() (GH-14355)Victor Stinner2019-06-251-53/+0
| | | | | | | Remove sys.getcheckinterval() and sys.setcheckinterval() functions. They were deprecated since Python 3.2. Use sys.getswitchinterval() and sys.setswitchinterval() instead. Remove also check_interval field of the PyInterpreterState structure.
* bpo-37316: mmap.mmap() passes the wrong variable to PySys_Audit() (GH-14152)Zackery Spytz2019-06-211-0/+1
| | | Also, add a missing call to va_end() in PySys_Audit().
* bpo-36710: Use tstate in pylifecycle.c (GH-14249)Victor Stinner2019-06-191-2/+2
| | | | In pylifecycle.c: pass tstate argument, rather than interp argument, to functions.
* bpo-36710: Pass explicitly tstate in sysmodule.c (GH-14060)Victor Stinner2019-06-131-170/+244
| | | | | | | | * Replace global var Py_VerboseFlag with interp->config.verbose. * Add _PyErr_NoMemory(tstate) function. * Add tstate parameter to _PyEval_SetCoroutineOriginTrackingDepth() and move the function to the internal API. * Replace _PySys_InitMain(runtime, interp) with _PySys_InitMain(runtime, tstate).
* Revert "bpo-36818: Add PyInterpreterState.runtime field. (gh-13129)" (GH-13795)Victor Stinner2019-06-041-16/+15
| | | This reverts commit 396e0a8d9dc65453cb9d53500d0a620602656cfe.

* bpo-36933: Remove sys.set_coroutine_wrapper (marked for removal in 3.8) ↵Matthias Bussonnier2019-05-281-58/+0
| | | | | | | | | | (GH-13577) It has been documented as deprecated and to be removed in 3.8; From a comment on another thread – which I can't find ; leave get_coro_wrapper() for now, but always return `None`. https://bugs.python.org/issue36933
* bpo-36763: Implement the PEP 587 (GH-13592)Victor Stinner2019-05-271-28/+28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * 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-36829: Add _PyErr_WriteUnraisableMsg() (GH-13488)Victor Stinner2019-05-271-4/+5
| | | | | * sys.unraisablehook: add 'err_msg' field to UnraisableHookArgs. * Use _PyErr_WriteUnraisableMsg() in _ctypes _DictRemover_call() and gc delete_garbage().
* bpo-36842: Implement PEP 578 (GH-12613)Steve Dower2019-05-231-0/+311
| | | Adds sys.audit, sys.addaudithook, io.open_code, and associated C APIs.
* bpo-36829: Add sys.unraisablehook() (GH-13187)Victor Stinner2019-05-221-0/+28
| | | | | | | | | | | | | | | | | | | Add new sys.unraisablehook() function which can be overridden to control how "unraisable exceptions" are handled. It is called when an exception has occurred but there is no way for Python to handle it. For example, when a destructor raises an exception or during garbage collection (gc.collect()). Changes: * Add an internal UnraisableHookArgs type used to pass arguments to sys.unraisablehook. * Add _PyErr_WriteUnraisableDefaultHook(). * The default hook now ignores exception on writing the traceback. * test_sys now uses unittest.main() to automatically discover tests: remove test_main(). * Add _PyErr_Init(). * Fix PyErr_WriteUnraisable(): hold a strong reference to sys.stderr while using it
* bpo-36594: Fix incorrect use of %p in format strings (GH-12769)Zackery Spytz2019-05-061-4/+4
| | | In addition, fix some other minor violations of C99.
* bpo-36775: _PyCoreConfig only uses wchar_t* (GH-13062)Victor Stinner2019-05-021-24/+3
| | | | | | | | | | | | | | | | | _PyCoreConfig: Change filesystem_encoding, filesystem_errors, stdio_encoding and stdio_errors fields type from char* to wchar_t*. Changes: * PyInterpreterState: replace fscodec_initialized (int) with fs_codec structure. * Add get_error_handler_wide() and unicode_encode_utf8() helper functions. * Add error_handler parameter to unicode_encode_locale() and unicode_decode_locale(). * Remove _PyCoreConfig_SetString(). * Rename _PyCoreConfig_SetWideString() to _PyCoreConfig_SetString(). * Rename _PyCoreConfig_SetWideStringFromString() to _PyCoreConfig_DecodeLocale().
* bpo-36710: Add runtime variable to Py_InitializeEx() (GH-12939)Victor Stinner2019-04-241-10/+12
| | | | | | | | Py_InitializeEx() now uses a runtime variable passed to subfunctions, rather than working directly on the global variable _PyRuntime. Add 'runtime' parameter to _PyCoreConfig_Write(), _PySys_Create(), _PySys_InitMain(), _PyGILState_Init(), emit_stderr_warning_for_legacy_locale() and other subfunctions.
* bpo-36447, bpo-36447: Fix refleak in _PySys_InitMain() (GH-12586)Pablo Galindo2019-03-271-0/+1
| | | Fix refleak in sysmodule.c when calling SET_SYS_FROM_STRING_BORROW.
* bpo-36444: Remove _PyMainInterpreterConfig (GH-12571)Victor Stinner2019-03-271-34/+85
|
* bpo-36301: Remove _PyCoreConfig.preconfig (GH-12546)Victor Stinner2019-03-261-4/+5
| | | | | | * Replace _PyCoreConfig.preconfig with 3 new fields in _PyCoreConfig: isolated, use_environment, dev_mode. * Add _PyPreCmdline.dev_mode. * Add _Py_PreInitializeFromPreConfigInPlace().
* bpo-36370: Check for PyErr_Occurred() after PyImport_GetModule() (GH-12504)Stefan Krah2019-03-251-1/+3
|
* bpo-36236: Handle removed cwd at Python init (GH-12424)Victor Stinner2019-03-191-10/+12
| | | | | | | | At Python initialization, the current directory is no longer prepended to sys.path if it has been removed. Rename _PyPathConfig_ComputeArgv0() to _PyPathConfig_ComputeSysPath0() to avoid confusion between argv[0] and sys.path[0].
* bpo-36301: Add _PyWstrList structure (GH-12343)Victor Stinner2019-03-151-21/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Replace messy _Py_wstrlist_xxx() functions with a new clean _PyWstrList structure and new _PyWstrList_xxx() functions. Changes: * Add _PyCoreConfig.use_module_search_paths to decide if _PyCoreConfig.module_search_paths should be computed or not, to support empty search path list. * _PyWstrList_Clear() sets length to 0 and items to NULL, whereas _Py_wstrlist_clear() only freed memory. * _PyWstrList_Append() returns an int, whereas _Py_wstrlist_append() returned _PyInitError. * _PyWstrList uses Py_ssize_t for the length, instead of int. * Replace (int, wchar_t**) with _PyWstrList in: * _PyPreConfig * _PyCoreConfig * _PyPreCmdline * _PyCmdline * Replace "int orig_argv; wchar_t **orig_argv;" with "_PyWstrList orig_argv". * _PyCmdline and _PyPreCmdline now also copy wchar_argv. * Rename _PyArgv_Decode() to _PyArgv_AsWstrList(). * PySys_SetArgvEx() now pass the fixed (argc, argv) to _PyPathConfig_ComputeArgv0() (don't pass negative argc or NULL argv). * _PyOS_GetOpt() uses Py_ssize_t
* bpo-36142: Add _PyPreConfig.allocator (GH-12181)Victor Stinner2019-03-051-1/+1
| | | | | | * Move 'allocator' and 'dev_mode' fields from _PyCoreConfig to _PyPreConfig. * Fix InitConfigTests of test_embed: dev_mode sets allocator to "debug", add a new tests for env vars with dev mode enabled.
* bpo-36142: Add _PyPreConfig.utf8_mode (GH-12174)Victor Stinner2019-03-051-1/+1
| | | | | | | | | | | | * Move following fields from _PyCoreConfig to _PyPreConfig: * coerce_c_locale * coerce_c_locale_warn * legacy_windows_stdio * utf8_mode * _PyPreConfig_ReadFromArgv() is now responsible to choose the filesystem encoding * _PyPreConfig_Write() now sets the LC_CTYPE locale
* bpo-36142: Add _PyPreConfig structure (GH-12172)Victor Stinner2019-03-051-2/+2
| | | | | | * Add _PyPreConfig structure * Move 'ignored' and 'use_environment' fields from _PyCoreConfig to _PyPreConfig * Add a new "_PyPreConfig preconfig;" field to _PyCoreConfig
* bpo-35890 : Fix some API calling consistency (GH-11742)Minmin Gong2019-02-031-3/+3
| | | | Unicode version of Windows APIs are used in places, but not for GetVersionEx in Python/sysmodule.c The wcstok_s is called on Windows in Modules/main.c and PC/launcher.c, but not in Python/pathconfig.c
* bpo-33895: Relase GIL while calling functions that acquire Windows loader ↵Tony Roberts2019-02-021-0/+2
| | | | | lock (GH-7789) LoadLibrary, GetProcAddress, FreeLibrary and GetModuleHandle acquire the system loader lock. Calling these while holding the GIL will cause a deadlock on the rare occasion that another thread is detaching and needs to destroy its thread state at the same time.
* bpo-35713: Reorganize sys module initialization (GH-11658)Victor Stinner2019-01-231-19/+80
| | | | | | | | | * Rename _PySys_BeginInit() to _PySys_InitCore(). * Rename _PySys_EndInit() to _PySys_InitMain(). * Add _PySys_Create(). It calls _PySys_InitCore() which becomes private. * Add _PySys_SetPreliminaryStderr(). * Rename _Py_ReadyTypes() to _PyTypes_Init(). * Misc code cleanup.
* bpo-35713: Rework Python initialization (GH-11647)Victor Stinner2019-01-221-16/+0
| | | | | | | | | | | | | | | | | | | * 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-35742: Fix test_envar_unimportable in test_builtin. (GH-11561)Serhiy Storchaka2019-01-151-10/+15
| | | | | Handle the case of an empty module name in PYTHONBREAKPOINT. Fixes a regression introduced in bpo-34756.
