* gh-84436: Implement Immortal Objects (gh-19474)Eddie Elizondo2023-04-221-1/+29
| | | | | | | | | This is the implementation of PEP683 Motivation: The PR introduces the ability to immortalize instances in CPython which bypasses reference counting. Tagging objects as immortal allows up to skip certain operations when we know that the object will be around for the entire execution of the runtime. Note that this by itself will bring a performance regression to the runtime due to the extra reference count checks. However, this brings the ability of having truly immutable objects that are useful in other contexts such as immutable data sharing between sub-interpreters.
* gh-86682: Adds sys._getframemodulename as an alternative to using _getframe ↵Steve Dower2023-01-131-1/+70
| | | | | (GH-99520) Also updates calls in collections, doctest, enum, and typing modules to use _getframemodulename first when available.

* gh-95778: CVE-2020-10735: Prevent DoS by very large int() (#96499)Gregory P. Smith2022-09-021-1/+77
| | | | | | | | | | | | | | | | 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. Signed-off-by: Christian Heimes [Red Hat] <christian@python.org> Tons-of-polishing-up-by: Gregory P. Smith [Google] <greg@krypto.org> Reviews via the private PSRT repo via many others (see the NEWS entry in the PR). <!-- gh-issue-number: gh-95778 --> * Issue: gh-95778 <!-- /gh-issue-number --> I wrote up [a one pager for the release managers](https://docs.google.com/document/d/1KjuF_aXlzPUxTK4BMgezGJ2Pn7uevfX7g0_mvgHlL7Y/edit#). Much of that text wound up in the Issue. Backports PRs already exist. See the issue for links.

| | | | | | | :warning: :warning: Note for reviewers, hackers and fellow systems/low-level/compiler engineers :warning: :warning: If you have a lot of experience with this kind of shenanigans and want to improve the **first** version, **please make a PR against my branch** or **reach out by email** or **suggest code changes directly on GitHub**. If you have any **refinements or optimizations** please, wait until the first version is merged before starting hacking or proposing those so we can keep this PR productive.

* gh-90928: Statically Initialize the Keywords Tuple in Clinic-Generated Code ↵Eric Snow2022-08-111-3/+75
| | | | | | | | | | | | | | | | (gh-95860) We only statically initialize for core code and builtin modules. Extension modules still create the tuple at runtime. We'll solve that part of interpreter isolation separately. This change includes generated code. The non-generated changes are in: * Tools/clinic/clinic.py * Python/getargs.c * Include/cpython/modsupport.h * Makefile.pre.in (re-generate global strings after running clinic) * very minor tweaks to Modules/_codecsmodule.c and Python/Python-tokenize.c All other changes are generated code (clinic, global strings).

* bpo-41435: Add sys._current_exceptions() function (GH-21689)Julien Danjou2020-11-021-1/+21
| | | | | | 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-37999: No longer use __int__ in implicit integer conversions. (GH-15636)Serhiy Storchaka2020-05-261-26/+1
| | | | Only __index__ should be used to make integer conversions lossless.
* bpo-39489: Remove COUNT_ALLOCS special build (GH-18259)Victor Stinner2020-02-031-26/+1
| | | | | | | | | | | 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-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-37414: Remove sys.callstats() (GH-14398)Victor Stinner2019-06-261-38/+1
| | | | | 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.

| | | | | | | 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-36933: Remove sys.set_coroutine_wrapper (marked for removal in 3.8) ↵Matthias Bussonnier2019-05-281-28/+1
| | | | | | | | | | (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

| | | | | * 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 Dower2019-05-231-1/+33
| | | Adds sys.audit, sys.addaudithook, io.open_code, and associated C APIs.
* bpo-36829: Add sys.unraisablehook() (GH-13187)Victor Stinner2019-05-221-1/+17
| | | | | | | | | | | | | | | | | | | 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-35582: Argument Clinic: Optimize the "all boring objects" case. (GH-11520)Serhiy Storchaka2019-01-111-7/+11
| | | | | Use _PyArg_CheckPositional() and inlined code instead of PyArg_UnpackTuple() and _PyArg_UnpackStack() if all parameters are positional and use the "object" converter.
