* Check result of utc_to_seconds and skip fold probe in pure Python (GH-91582)Miss Islington (bot)2022-05-141-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The `utc_to_seconds` call can fail, here's a minimal reproducer on Linux: TZ=UTC python -c "from datetime import *; datetime.fromtimestamp(253402300799 + 1)" The old behavior still raised an error in a similar way, but only because subsequent calculations happened to fail as well. Better to fail fast. This also refactors the tests to split out the `fromtimestamp` and `utcfromtimestamp` tests, and to get us closer to the actual desired limits of the functions. As part of this, we also changed the way we detect platforms where the same limits don't necessarily apply (e.g. Windows). As part of refactoring the tests to hit this condition explicitly (even though the user-facing behvior doesn't change in any way we plan to guarantee), I noticed that there was a difference in the places that `datetime.utcfromtimestamp` fails in the C and pure Python versions, which was fixed by skipping the "probe for fold" logic for UTC specifically — since UTC doesn't have any folds or gaps, we were never going to find a fold value anyway. This should prevent some failures in the pure python `utcfromtimestamp` method on timestamps close to 0001-01-01. There are two separate news entries for this because one is a potentially user-facing change, the other is an internal code correctness change that, if anything, changes some error messages. The two happen to be coupled because of the test refactoring, but they are probably best thought of as independent changes.

| | | | | | | | | | ``pymain_run_python()`` now imports ``readline`` and ``rlcompleter`` before sys.path is extended to include the current working directory of an interactive interpreter. Non-interactive interpreters are not affected. Also move imports of ``re`` and ``keyword`` module to top level so they are materialized early, too. The ``keyword`` module is trivial and the ``re`` is already imported via ``inspect`` -> ``linecache``.
