* gh-103109: Document ignore_warnings() test support helper (GH-103110)Miss Islington (bot)2023-04-021-1/+1

* [3.11] gh-90867: test.support.wait_process() uses LONG_TIMEOUT (#99071) (#99098)Victor Stinner2022-11-041-3/+3
| | | | | | | | | The test.support.wait_process() function now uses a timeout of LONG_TIMEOUT seconds by default, instead of SHORT_TIMEOUT. It doesn't matter if a Python buildbot is slower, it only matters that the process completes. The timeout should just be shorter than "forever".

* [3.11] gh-95778: CVE-2020-10735: Prevent DoS by very large int() (#96500)Gregory P. Smith2022-09-021-0/+11
| | | | | | | | | | | | | | | | | | 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.

* bpo-40280: Skip socket, fork, subprocess tests on Emscripten (GH-31986)Christian Heimes2022-03-221-0/+16
| | | | | | | | | | | - Add requires_fork and requires_subprocess to more tests - Skip extension import tests if dlopen is not available - Don't assume that _testcapi is a shared extension - Skip a lot of socket tests that don't work on Emscripten - Skip mmap tests, mmap emulation is incomplete - venv does not work yet - Cannot get libc from executable The "entire" test suite is now passing on Emscripten with EMSDK from git head (91 suites are skipped).

* bpo-40280: Skip more tests/features that don't apply to Emscripten (GH-31791)Christian Heimes2022-03-101-1/+1
| | | | | | | - fd inheritance can't be modified because Emscripten doesn't support subprocesses anyway. - setpriority always fails - geteuid no longer causes problems with latest emsdk - umask is a stub - geteuid / getuid always return 0, but process cannot chown to random uid.
* bpo-40280: Block more non-working syscalls in Emscripten (GH-31757)Christian Heimes2022-03-081-2/+2
| | | | | | | | | - getgroups always fails. - geteuid and getegid always return 0 (root), which confuse tarfile and tests. - hardlinks (link, linkat) always fails. - non-encodable file names are not supported by NODERAWFS layer. - mark more tests with dependency on subprocess and multiprocessing. Mocking does not work if the module fails to import.
* bpo-46678: Fix Invalid cross device link in ↵Jason Wilkes2022-02-081-1/+2
| | | | | | | Lib/test/support/import_helper.py (GH-31204) In [Lib/test/support/import_helper.py](https://github.com/python/cpython/blob/master/Lib/test/support/import_helper.py), the function `make_legacy_pyc` makes a call to `os.rename` which can fail when the source and target live on different devices. This happens (for example) when `PYTHONPYCACHEPREFIX` is set to a directory anywhere on disk, while a ramdisk is mounted on `/tmp` (the latter of which is the default on various Linux distros). Replacing `os.rename` with `shutil.move` fixes this. Automerge-Triggered-By: GH:brettcannon

* bpo-45629: Improve test.support.skip_if_buildbot (GH-31094)Gregory P. Smith2022-02-031-4/+6
| | | | | | | It was added as part of #29222 to avoid running freeze tool tests on the buildbots but the logic was wrong so it did not skip tests on typical posix setup buildbots where the worker is launched from cron via an @reboot task and thus have no USER environment variable. This uses the canonical `getpass.getuser()` API rather than rolling its own attempt.

* bpo-45629: Add a test for the "freeze" tool. (gh-29222)Eric Snow2021-10-281-0/+11
| | | | | | | The "freeze" tool has been part of the repo for a long time. However, it hasn't had any tests in the test suite to guard against regressions. We add such a test here. This is especially important as there has been a lot of change recently related to frozen modules, with more to come. Note that as part of the test we build Python out-of-tree and install it in a temp dir. https://bugs.python.org/issue45629
* bpo-45410: regrtest -W leaves stdout/err FD unchanged (GH-28915)Victor Stinner2021-10-131-3/+5
| | | | | | | | | | | | support.print_warning() now stores the original value of sys.__stderr__ and uses it to log warnings. libregrtest uses the same stream to log unraisable exceptions and uncaught threading exceptions. Partially revert commit dbe213de7ef28712bbfdb9d94a33abb9c33ef0c2: libregrtest no longer replaces sys.__stdout__, sys.__stderr__, and stdout and stderr file descriptors. Remove also a few unused imports in libregrtest.
* bpo-45410: Enhance libregrtest -W/--verbose3 option (GH-28908)Victor Stinner2021-10-121-1/+3
| | | | | | | | | | | libregrtest -W/--verbose3 now also replace sys.__stdout__, sys.__stderr__, and stdout and stderr file descriptors (fd 1 and fd 2). support.print_warning() messages are now logged in the expected order. The "./python -m test test_eintr -W" command no longer logs into stdout if the test pass.
