* GH-115060: Speed up `pathlib.Path.glob()` by not scanning literal parts ↵Barney Gale2024-04-124-11/+42
| | | | | | | | | (#117732) Don't bother calling `os.scandir()` to scan for literal pattern segments, like `foo` in `foo/*.py`. Instead, append the segment(s) as-is and call through to the next selector with `exists=False`, which signals that the path might not exist. Subsequent selectors will call `os.scandir()` or `os.lstat()` to filter out missing paths as needed.

* gh-117376: Partial implementation of deferred reference counting (#117696)Sam Gross2024-04-129-21/+82
| | | | | This marks objects as using deferred refrence counting using the `ob_gc_bits` field in the free-threaded build and collects those objects during GC.
* gh-117764: Add more tests for signatures of builtins (GH-117816)Serhiy Storchaka2024-04-121-34/+265
| | | | | | | | | | | | Test signatures of all public builtins and methods of builtin classes in modules builtins, types, sys, and several other modules (either included in the list of standard builtin modules sys.builtin_module_names, or providing a public interface for such modules). Most builtins should have supported signatures, with few known exceptions. When more builtins will be converted to Argument Clinic or support of new signatures be implemented, they will be removed from the exception lists.

| | | | | | | | | | | | | | (#117502) This change gives a significant speedup, as the METH_FASTCALL calling convention is now used. The following bytes and bytearray methods are adapted: - count() - find() - index() - rfind() - rindex() Co-authored-by: Inada Naoki <songofacandy@gmail.com>
* gh-117752: Autoconf: fix -fno-semantic-interposition check (#117789)Erlend E. Aasland2024-04-122-8/+8

* gh-76785: Handle Legacy Interpreters Properly (gh-117490)Eric Snow2024-04-119-200/+454
| | | This is similar to the situation with threading._DummyThread. The methods (incl. __del__()) of interpreters.Interpreter objects must be careful with interpreters not created by interpreters.create(). The simplest thing to start with is to disable any method that modifies or runs in the interpreter. As part of this, the runtime keeps track of where an interpreter was created. We also handle interpreter "refcounts" properly.

| | | | A collection of small changes aimed at making the `_abc` module safe to use in a free-threaded build.
* gh-117649: Fix file descriptor leak in (expected) failing test case (#117780)Sam Gross2024-04-111-0/+3
| | | | | The test case is currently expected to fail in the free-threaded build. However, it fails before it gets a chance to close the write end of the pipe.
* gh-117649: Raise ImportError for unsupported modules in free-threaded build ↵Sam Gross2024-04-119-32/+103
| | | | | | | | | | (#117651) The free-threaded build does not currently support the combination of single-phase init modules and non-isolated subinterpreters. Ensure that `check_multi_interp_extensions` is always `True` for subinterpreters in the free-threaded build so that importing these modules raises an `ImportError`.
* gh-111506: Error if the limited API is used in free-threaded build (#117762)Sam Gross2024-04-111-0/+5
| | | | Issue a build time error if both `Py_LIMITED_API` and `Py_GIL_DISABLED` are defined.

* gh-117233: Detect support for several hashes at hashlib build time (GH-117234)Will Childs-Klein2024-04-112-10/+62
| | | | | | | | | | | | | | | | | | | | | | | Detect libcrypto BLAKE2, Shake, SHA3, and Truncated-SHA512 support at hashlib build time ## BLAKE2 While OpenSSL supports both "b" and "s" variants of the BLAKE2 hash function, other cryptographic libraries may lack support for one or both of the variants. 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`. ## 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. Co-authored-by: Gregory P.

* gh-117722: Fix Stream.readuntil with non-bytes buffer objects (#117723)Bruce Merry2024-04-115-14/+27
| | | | | | | | | | | | | gh-16429 introduced support for an iterable of separators in Stream.readuntil. Since bytes-like types are themselves iterable, this can introduce ambiguities in deciding whether the argument is an iterator of separators or a singleton separator. In gh-16429, only 'bytes' was considered a singleton, but this will break code that passes other buffer object types. Fix it by only supporting tuples rather than arbitrary iterables. Closes gh-117722.

Add a 'codegen' (Codegen) attribute to Clinic. * Remove libclinic.crenderdata module: move code to libclinic.codegen. * BlockPrinter.print_block(): remove unused 'limited_capi' argument.

* gh-76785: Add More Tests to test_interpreters.test_api (gh-117662)Eric Snow2024-04-1118-418/+2012
| | | In addition to the increase test coverage, this is a precursor to sorting out how we handle interpreters created directly via the C-API.
* GH-117586: Speed up `pathlib.Path.walk()` by working with strings (#117726)Barney Gale2024-04-114-71/+52
| | | | | | | | | | | Move `pathlib.Path.walk()` implementation into `glob._Globber`. The new `glob._Globber.walk()` classmethod works with strings internally, which is a little faster than generating `Path` objects and keeping them normalized. The `pathlib.Path.walk()` method converts the strings back to path objects. In the private pathlib ABCs, our existing subclass of `_Globber` ensures that `PathBase` instances are used throughout. Follow-up to #117589.
* GH-117586: Speed up `pathlib.Path.glob()` by working with strings (#117589)Barney Gale2024-04-104-195/+269
| | | | | | | | | | | | Move pathlib globbing implementation into a new private class: `glob._Globber`. This class implements fast string-based globbing. It's called by `pathlib.Path.glob()`, which then converts strings back to path objects. In the private pathlib ABCs, add a `pathlib._abc.Globber` subclass that works with `PathBase` objects rather than strings, and calls user-defined path methods like `PathBase.stat()` rather than `os.stat()`. This sets the stage for two more improvements: - GH-115060: Query non-wildcard segments with `lstat()` - GH-116380: Unify `pathlib` and `glob` implementations of globbing. No change to the implementations of `glob.glob()` and `glob.iglob()`.
