* [3.7] gh-95778: CVE-2020-10735: Prevent DoS by very large int() (GH-96504)Gregory P. Smith2022-09-061-0/+10
| | | | | | | | | | | | | | | | Converting between `int` and `str` in bases other than 2 (binary), 4, 8 (octal), 16 (hexadecimal), or 32 such as base 10 (decimal) now raises a `ValueError` if the number of digits in string form is above a limit to avoid potential denial of service attacks due to the algorithmic complexity. This is a mitigation for CVE-2020-10735 (https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2020-10735). This new limit can be configured or disabled by environment variable, command line flag, or :mod:`sys` APIs. See the `Integer String Conversion Length Limitation` documentation. The default limit is 4300 digits in string form. Patch by Gregory P. Smith [Google] and Christian Heimes [Red Hat] with feedback from Victor Stinner, Thomas Wouters, Steve Dower, Ned Deily, and Mark Dickinson.

(cherry picked from commit ecb035cd14c11521276343397151929a94018a22) * bpo-37957: Allow regrtest to receive a file with test (and subtests) to ignore (GH-16989) When building Python in some uncommon platforms there are some known tests that will fail. Right now, the test suite has the ability to ignore entire tests using the -x option and to receive a filter file using the --matchfile filter. The problem with the --matchfile option is that it receives a file with patterns to accept and when you want to ignore a couple of tests and subtests, is too cumbersome to lists ALL tests that are not the ones that you want to accept and he problem with -x is that is not easy to ignore just a subtests that fail and the whole test needs to be ignored. For these reasons, add a new option to allow to ignore a list of test and subtests for these situations.

* bpo-34945: Buffer output in test suite only when creating junit file (GH-10204)Miss Islington (bot)2018-10-292-14/+16
| | | | | | | | | | | | | | After commit d0f49d2f5085ca68e3dc8725f1fb1c9674bfb5ed, the output of the test suite is always buffered as the test output needs to be included in the JUnit file in same cases (as when a test fails). This has the consequence that printing or using debuggers (like pdb) in the test suite does not result in a good user experience anymore. This commit modifies the test suite runner so it only captures the test output when the JUnit file is requested to fix the regression so prints and debuggers are usable again.

| | | | | | | | | | | | | | Historically, -m added the empty string as sys.path zero, meaning it resolved imports against the current working directory, the same way -c and the interactive prompt do. This changes the sys.path initialisation to add the *starting* working directory as sys.path[0] instead, such that changes to the working directory while the program is running will have no effect on imports when using the -m switch.
