* bpo-43510: Implement PEP 597 opt-in EncodingWarning. (GH-19481)Inada Naoki2021-03-291-1/+3
| | | | | | | | | | | See [PEP 597](https://www.python.org/dev/peps/pep-0597/). * Add `-X warn_default_encoding` and `PYTHONWARNDEFAULTENCODING`. * Add EncodingWarning * Add io.text_encoding() * open(), TextIOWrapper() emits EncodingWarning when encoding is omitted and warn_default_encoding is enabled. * _pyio.TextIOWrapper() uses UTF-8 as fallback default encoding used when failed to import locale module. (used during building Python) * bz2, configparser, gzip, lzma, pathlib, tempfile modules use io.text_encoding(). * What's new entry

* bpo-43268: Pass interp rather than tstate to internal functions (GH-24580)Victor Stinner2021-02-191-43/+42
| | | | | | | | | | | | | | | Pass the current interpreter (interp) rather than the current Python thread state (tstate) to internal functions which only use the interpreter. Modified functions: * _PyXXX_Fini() and _PyXXX_ClearFreeList() functions * _PyEval_SignalAsyncExc(), make_pending_calls() * _PySys_GetObject(), sys_set_object(), sys_set_object_id(), sys_set_object_str() * should_audit(), set_flags_from_config(), make_flags() * _PyAtExit_Call() * init_stdio_encoding() * etc.
* bpo-43268: Remove abusive usage of tstate in sysmodule.c (#24581)Victor Stinner2021-02-191-18/+12
| | | | Remove explicit tstate usage in sysmodule.c when it's only used raise exceptions: get it implicitly using PyErr_XXX() functions.
* bpo-42955: Rename module_names to sys.stdlib_module_names (GH-24332)Victor Stinner2021-01-251-5/+5
| | | | * Rename _Py_module_names to _Py_stdlib_module_names. * Rename Python/module_names.h to Python/stdlib_module_names.h.

* bpo-42500: Fix recursion in or after except (GH-23568)Mark Shannon2020-12-021-3/+1
| | | * Use counter, rather boolean state when handling soft overflows.
* bpo-42260: Initialize time and warnings earlier at startup (GH-23249)Victor Stinner2020-11-121-0/+5
| | | | | | | | | | * Call _PyTime_Init() and _PyWarnings_InitState() earlier during the Python initialization. * Inline _PyImportHooks_Init() into _PySys_InitCore(). * The _warnings initialization function no longer call _PyWarnings_InitState() to prevent resetting filters_version to 0. * _PyWarnings_InitState() now returns an int and no longer clear the state in case of error (it's done anyway at Python exit). * Rework init_importlib(), fix refleaks on errors.
* bpo-42260: Compute the path config in the main init (GH-23211)Victor Stinner2020-11-101-8/+14
| | | | | | | | | | | | | | | | | | | | | The path configuration is now computed in the "main" initialization. The core initialization no longer computes it. * Add _PyConfig_Read() function to read the configuration without computing the path configuration. * pyinit_core() no longer computes the path configuration: it is now computed by init_interp_main(). * The path configuration output members of PyConfig are now optional: * executable * base_executable * prefix * base_prefix * exec_prefix * base_exec_prefix * _PySys_UpdateConfig() now skips NULL strings in PyConfig. * _testembed: Rename test_set_config() to test_init_set_config() for consistency with other tests.
* bpo-42260: Add _PyConfig_FromDict() (GH-23167)Victor Stinner2020-11-051-1/+3
| | | | | | | * Rename config_as_dict() to _PyConfig_AsDict(). * Add 'module_search_paths_set' to _PyConfig_AsDict(). * Add _PyConfig_FromDict(). * Add get_config() and set_config() to _testinternalcapi. * Add config_check_consistency().
* bpo-42260: Main init modify sys.flags in-place (GH-23150)Victor Stinner2020-11-041-46/+67
| | | | | | | | | | | When Py_Initialize() is called twice, the second call now updates more sys attributes for the configuration, rather than only sys.argv. * Rename _PySys_InitMain() to _PySys_UpdateConfig(). * _PySys_UpdateConfig() now modifies sys.flags in-place, instead of creating a new flags object. * Remove old commented sys.flags flags (unbuffered and skip_first). * Add private _PySys_GetObject() function. * When Py_Initialize(), Py_InitializeFromConfig() and
* bpo-41435: Add sys._current_exceptions() function (GH-21689)Julien Danjou2020-11-021-0/+16
| | | | | | This adds a new function named sys._current_exceptions() which is equivalent ot sys._current_frames() except that it returns the exceptions currently handled by other threads. It is equivalent to calling sys.exc_info() for each running thread.
* bpo-42006: Stop using PyDict_GetItem, PyDict_GetItemString and ↵Serhiy Storchaka2020-10-261-24/+38
| | | | | | | | | | | _PyDict_GetItemId. (GH-22648) These functions are considered not safe because they suppress all internal errors and can return wrong result. PyDict_GetItemString and _PyDict_GetItemId can also silence current exception in rare cases. Remove no longer used _PyDict_GetItemId. Add _PyDict_ContainsId and rename _PyDict_Contains into _PyDict_Contains_KnownHash.
* bpo-42002: Clean up initialization of the sys module. (GH-22642)Serhiy Storchaka2020-10-111-107/+45
| | | Makes the code clearer and make errors handling more correct.
* bpo-23427: Add sys.orig_argv attribute (GH-20729)Victor Stinner2020-06-291-0/+1
| | | | | | | Add sys.orig_argv attribute: the list of the original command line arguments passed to the Python executable. Rename also PyConfig._orig_argv to PyConfig.orig_argv and document it.

* bpo-40826: Add _Py_EnsureTstateNotNULL() macro (GH-20571)Victor Stinner2020-06-011-1/+1
| | | | Add _Py_EnsureTstateNotNULL(tstate) macro: call Py_FatalError() if tstate is NULL, the error message contains the current function name.
* bpo-40421: Add PyFrame_GetBack() function (GH-19765)Victor Stinner2020-04-291-4/+6
| | | | | | New PyFrame_GetBack() function: get the frame next outer frame. Replace frame->f_back with PyFrame_GetBack(frame) in most code but frameobject.c, ceval.c and genobject.c.
* bpo-40334: Rename PyConfig.use_peg to _use_peg_parser (GH-19670)Victor Stinner2020-04-231-3/+1
| | | | | | | | | | | * Rename PyConfig.use_peg to _use_peg_parser * Document PyConfig._use_peg_parser and mark it a deprecated * Mark -X oldparser option and PYTHONOLDPARSER env var as deprecated in the documentation. * Add use_old_parser() and skip_if_new_parser() to test.support * Remove sys.flags.use_peg: use_old_parser() uses _testinternalcapi.get_configs() instead. * Enhance test_embed tests * subprocess._args_from_interpreter_flags() copies -X oldparser

* bpo-40268: Remove unused osdefs.h includes (GH-19532)Victor Stinner2020-04-151-2/+2
| | | When the include is needed, add required symbol in a comment.
* bpo-40268: Remove unused pycore_pymem.h includes (GH-19531)Victor Stinner2020-04-151-3/+3
|
* bpo-40268: Remove explicit pythread.h includes (#19529)Victor Stinner2020-04-151-1/+0
| | | | Remove explicit pythread.h includes: it is always included by Python.h.
* bpo-40170: Convert PyObject_IS_GC() macro to a function (GH-19464)Hai Shi2020-04-141-1/+2

* bpo-40268: Remove a few pycore_pystate.h includes (GH-19510)Victor Stinner2020-04-141-2/+1
|
* bpo-40268: Rename _PyInterpreterState_GET_UNSAFE() (GH-19509)Victor Stinner2020-04-141-2/+2
| | | | | | | Rename _PyInterpreterState_GET_UNSAFE() to _PyInterpreterState_GET() for consistency with _PyThreadState_GET() and to have a shorter name (help to fit into 80 columns). Add also "assert(tstate != NULL);" to the function.
* bpo-40268: Include explicitly pycore_interp.h (GH-19505)Victor Stinner2020-04-141-1/+3
| | | | pycore_pystate.h no longer includes pycore_interp.h: it's now included explicitly in files accessing PyInterpreterState.
* bpo-40268: Add _PyInterpreterState_GetConfig() (GH-19492)Victor Stinner2020-04-131-8/+7
| | | | | | | | Don't access PyInterpreterState.config member directly anymore, but use new functions: * _PyInterpreterState_GetConfig() * _PyInterpreterState_SetConfig() * _Py_GetConfig()
* bpo-38644: Add _PySys_Audit() which takes tstate (GH-19180)Victor Stinner2020-03-261-60/+110
| | | | | | | | | | | | | | | Add _PySys_Audit() function to the internal C API: similar to PySys_Audit(), but requires a mandatory tstate parameter. Cleanup sys_audit_tstate() code: remove code path for NULL tstate, since the function exits at entry if tstate is NULL. Remove also code path for NULL tstate->interp: should_audit() now ensures that it is not NULL (even if tstate->interp cannot be NULL in practice). PySys_AddAuditHook() now checks if tstate is not NULL to decide if tstate can be used or not, and tstate is set to NULL if the runtime is not initialized yet. Use _PySys_Audit() in sysmodule.c.
* bpo-38410: Properly handle PySys_Audit() failures (GH-16657)Zackery Spytz2020-03-261-6/+10

* bpo-35370: Add _PyEval_SetTrace() function (GH-18975)Victor Stinner2020-03-131-24/+48
| | | | | | | | | * sys.settrace(), sys.setprofile() and _lsprof.Profiler.enable() now properly report PySys_Audit() error if "sys.setprofile" or "sys.settrace" audit event is denied. * Add _PyEval_SetProfile() and _PyEval_SetTrace() function: similar to PyEval_SetProfile() and PyEval_SetTrace() but take a tstate parameter and return -1 on error. * Add _PyObject_FastCallTstate() function.
* bpo-1294959: Add sys.platlibdir attribute (GH-18381)Victor Stinner2020-03-101-2/+9
| | | | | | | | | | | | | Add --with-platlibdir option to the configure script: name of the platform-specific library directory, stored in the new sys.platlitdir attribute. It is used to build the path of platform-specific dynamic libraries and the path of the standard library. It is equal to "lib" on most platforms. On Fedora and SuSE, it is equal to "lib64" on 64-bit systems.

* bpo-39877: _PyRuntimeState.finalizing becomes atomic (GH-18816)Victor Stinner2020-03-061-2/+3
| | | | | | | | | | | | Convert _PyRuntimeState.finalizing field to an atomic variable: * Rename it to _finalizing * Change its type to _Py_atomic_address * Add _PyRuntimeState_GetFinalizing() and _PyRuntimeState_SetFinalizing() functions * Remove _Py_CURRENTLY_FINALIZING() function: replace it with testing directly _PyRuntimeState_GetFinalizing() value Convert _PyRuntimeState_GetThreadState() to static inline function.
* closes bpo-39870: Remove unused arg from sys_displayhook_unencodable. (GH-18796)Andy Lester2020-03-061-3/+3
| | | Also move int err to its innermost scope.
* closes bpo-39605: Fix some casts to not cast away const. (GH-18453)Andy Lester2020-02-121-1/+1
| | | | | | | | | | | | | | | gcc -Wcast-qual turns up a number of instances of casting away constness of pointers. Some of these can be safely modified, by either: Adding the const to the type cast, as in: - return _PyUnicode_FromUCS1((unsigned char*)s, size); + return _PyUnicode_FromUCS1((const unsigned char*)s, size); or, Removing the cast entirely, because it's not necessary (but probably was at one time), as in: - PyDTrace_FUNCTION_ENTRY((char *)filename, (char *)funcname, lineno); + PyDTrace_FUNCTION_ENTRY(filename, funcname, lineno); These changes will not change code, but they will make it much easier to check for errors in consts

| | | | Replace direct acccess to PyObject.ob_refcnt with usage of the Py_REFCNT() macro.
* 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-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.
