* [3.12] gh-119577: Adjust DeprecationWarning when testing element truth ↵Gregory P. Smith2024-08-061-1/+1
| | | | | | | | | | | | | values in Element tree (GH-119762) (#120190) gh-119577: Adjust DeprecationWarning when testing element truth values in ElementTree (GH-119762) Adjust DeprecationWarning when testing element truth values in ElementTree, we're planning to go with the more natural True return rather than a disruptive harder to code around exception raise, and are deferring the behavior change for a few more releases.

| | | | | | | `_datetime` (gh-120431) The _strptime module object was cached in a static local variable (in the datetime.strptime() implementation). That's a problem when it crosses isolation boundaries, such as reinitializing the runtme or between interpreters. This change fixes the problem by dropping the static variable, instead always relying on the normal sys.modules cache (via PyImport_Import()).

* [3.12] gh-119213: Be More Careful About _PyArg_Parser.kwtuple Across ↵Eric Snow2024-05-222-1/+80
| | | | | | | | | | | Interpreters (gh-119331) (gh-119425) _PyArg_Parser holds static global data generated for modules by Argument Clinic. The _PyArg_Parser.kwtuple field is a tuple object, even though it's stored within a static global. In some cases the tuple is statically allocated and thus it's okay that it gets shared by multiple interpreters. However, in other cases the tuple is set lazily, allocated from the heap using the active interprepreter at the point the tuple is needed. This is a problem once that interpreter is destroyed since _PyArg_Parser.kwtuple becomes at dangling pointer, leading to crashes. It isn't a problem if the tuple is allocated under the main interpreter, since its lifetime is bound to the lifetime of the runtime. The solution here is to temporarily switch to the main interpreter. The alternative would be to always statically allocate the tuple. This change also fixes a bug where only the most recent parser was added to the global linked list. (cherry picked from commit 81865002aee8eaaeb3c7e402f86183afa6de77bf)

This commit modifies `hashlib`'s C code to detect whether or not the linked libcrypto supports each BLAKE2 variant, and elides references to each variant's NID accordingly. In cases where the underlying libcrypto doesn't fully support BLAKE2, CPython's `./configure` script can be given the following flag to use CPython's interned BLAKE2 implementation: `--with-builtin-hashlib-hashes=blake2`. GH-GH- SHA3, Shake, & truncated SHA512. Detect BLAKE2, SHA3, Shake, & truncated SHA512 support in the OpenSSL-ish libcrypto library at build time. This helps allow hashlib's `_hashopenssl` to be used with libraries that do not to support every algorithm that upstream OpenSSL does. Such as AWS-LC & BoringSSL.

| | | | | | | | | | | | | | (#117689) gh-117534: Add checking for input parameter in iso_to_ymd (GH-117543) Moves the validation for invalid years in the C implementation of the `datetime` module into a common location between `fromisoformat` and `fromisocalendar`, which improves the error message and fixes a failed assertion when parsing invalid ISO 8601 years using one of the "ISO weeks" formats. --------- (cherry picked from commit d5f1139c79525b4e7e4e8ad8c3e5fb831bbc3f28) Co-authored-by: Vlad4896 <166005126+Vlad4896@users.noreply.github.com> Co-authored-by: blurb-it[bot] <43283697+blurb-it[bot]@users.noreply.github.com>
