* [3.11] gh-95778: CVE-2020-10735: Prevent DoS by very large int() (#96500)Gregory P. Smith2022-09-023-3/+161
| | | | | | | | | | | | | | | | | | 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.

* [3.11] gh-94938: Fix errror detection of unexpected keyword arguments ↵Serhiy Storchaka2022-07-281-85/+57
| | | | | | | | | | | | | | | (GH-94999) (GH-95353) When keyword argument name is an instance of a str subclass with overloaded methods __eq__ and __hash__, the former code could not find the name of an extraneous keyword argument to report an error, and _PyArg_UnpackKeywords() returned success without setting the corresponding cell in the linearized arguments array. But since the number of expected initialized cells is determined as the total number of passed arguments, this lead to reading NULL as a keyword parameter value, that caused SystemError or crash or other undesired behavior.

* [3.11] gh-93883: elide traceback indicators when possible (GH-93994) (GH-94740)John Belmonte2022-07-111-4/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Elide traceback column indicators when the entire line of the frame is implicated. This reduces traceback length and draws more attention to the remaining (very relevant) indicators.

* [3.11] gh-92228: disable the compiler's 'small exit block inlining' ↵Christian Heimes2022-07-071-0/+14
| | | | | | | | | | optimization for blocks that have a line number (GH-94592) (GH-94643) Inlining of code that corresponds to source code lines, can make it hard to distinguish later between code which is only reachable from except handlers, and that which is reachable in normal control flow. This caused problems with the debugger's jump feature. This PR turns off the inlining optimisation for code which has line numbers. We still inline things like the implicit "return None"..
