* [3.11] gh-108851: Fix tomllib recursion tests (#108853) (#109013)Victor Stinner2023-09-061-26/+31
| | | | | | | | | | | | | | | | | | | | | | | gh-108851: Fix tomllib recursion tests (#108853) * Add get_recursion_available() and get_recursion_depth() functions to the test.support module. * Change infinite_recursion() default max_depth from 75 to 100. * Fix test_tomllib recursion tests for WASI buildbots: reduce the recursion limit and compute the maximum nested array/dict depending on the current available recursion limit. * test.pythoninfo logs sys.getrecursionlimit(). * Enhance test_sys tests on sys.getrecursionlimit() and sys.setrecursionlimit(). Backport notes: * Set support.infinite_recursion() minimum to 4 frames. * test_support.test_get_recursion_depth() uses limit-2, apparently f-string counts for 2 frames in Python 3.11. * test_sys.test_setrecursionlimit_to_depth() tests depth+2 instead of depth+1. (cherry picked from commit 8ff11425783806f8cb78e99f667546b1f7f3428e)

| | | | | | | | | | | | element ob_digit array for 0 and False (GH-100663) (#100717) gh-100637: Fix int and bool __sizeof__ calculation to include the 1 element ob_digit array for 0 and False (GH-100663) Fixes behaviour where int (and subtypes like bool) __sizeof__ under-reports true size as it did not take into account the size 1 `ob_digit` array for the zero int.

* [3.11] gh-95778: CVE-2020-10735: Prevent DoS by very large int() (#96500)Gregory P. Smith2022-09-021-2/+8
| | | | | | | | | | | | | | | | | | Integer to and from text conversions via CPython's bignum `int` type is not safe against denial of service attacks due to malicious input. Very large input strings with hundred thousands of digits can consume several CPU seconds. This PR comes fresh from a pile of work done in our private PSRT security response team repo.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a new Py_TPFLAGS_DISALLOW_INSTANTIATION type flag to disallow creating type instances: set tp_new to NULL and don't create the "__new__" key in the type dictionary. The flag is set automatically on static types if tp_base is NULL or &PyBaseObject_Type and tp_new is NULL. Use the flag on the following types: * _curses.ncurses_version type * _curses_panel.panel * _tkinter.Tcl_Obj * _tkinter.tkapp * _tkinter.tktimertoken * _xxsubinterpretersmodule.ChannelID * sys.flags type * sys.getwindowsversion() type * sys.version_info type Update MyStr example in the C API documentation to use Py_TPFLAGS_DISALLOW_INSTANTIATION. Add _PyStructSequence_InitType() function to create a structseq type with the Py_TPFLAGS_DISALLOW_INSTANTIATION flag set. type_new() calls _PyType_CheckConsistency() at exit.
