* bpo-44441: _PyImport_Fini2() resets PyImport_Inittab (GH-26874) (GH-26878)Victor Stinner2021-06-231-0/+3
| | | | | | | Py_RunMain() now resets PyImport_Inittab to its initial value at exit. It must be possible to call PyImport_AppendInittab() or PyImport_ExtendInittab() at each Python initialization. (cherry picked from commit 489699ca05bed5cfd10e847d8580840812b476cd)

| | | | | | | | | | | | (GH-26522) When compiling an AST object with a direct / indirect reference cycles, on the conversion phase because of exceeding amount of calls, a segfault was raised. This patch adds recursion guards to places for preventing user inputs to not to crash AST but instead raise a RecursionError..

On Windows, _PyEval_SignalReceived() now always sets eval_breaker to 1 since it cannot test _Py_ThreadCanHandleSignals(), and eval_frame_handle_pending() always calls _Py_ThreadCanHandleSignals() to recompute eval_breaker.

* bpo-41894: Fix UnicodeDecodeError while loading native module (GH-22466)Miss Skeleton (bot)2020-10-153-8/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When running in a non-UTF-8 locale, if an error occurs while importing a native Python module (say because a dependent share library is missing), the error message string returned may contain non-ASCII code points causing a UnicodeDecodeError. PyUnicode_DecodeFSDefault is used for buffers which may contain filesystem paths. For consistency with os.strerror(), PyUnicode_DecodeLocale is used for buffers which contain system error messages. While the shortname parameter is always encoded in ASCII according to PEP 489, it is left decoded using PyUnicode_FromString to minimize the changes and since it should not affect the decoding (albeit _potentially_ slower). In dynload_hpux, since the error buffer contains a message generated from a static ASCII string and the module filesystem path, PyUnicode_DecodeFSDefault is used instead of PyUnicode_DecodeLocale as is used elsewhere. * bpo-41894: Fix bugs in dynload error msg handling For both dynload_aix and dynload_hpux, properly handle the possibility that decoding strings may return NULL and when such an error happens, properly decrement any previously decoded strings and return early. In addition, in dynload_aix, ensure that we pass the decoded string *object* pathname_ob to PyErr_SetImportError instead of the original pathname buffer.

| | | | | | | | | | | | | | | | | | | | Partially revert commit ac46eb4ad6662cf6d771b20d8963658b2186c48c: "bpo-38113: Update the Python-ast.c generator to PEP384 (gh-15957)". Using a module state per module instance is causing subtle practical problems. For example, the Mercurial project replaces the __import__() function to implement lazy import, whereas Python expected that "import _ast" always return a fully initialized _ast module. Add _PyAST_Fini() to clear the state at exit. The _ast module has no state (set _astmodule.m_size to 0). Remove astmodule_traverse(), astmodule_clear() and astmodule_free() functions..
