* gh-98636: Fix detecting gdbm_compat for _dbm module (#98643)Michał Górny2023-01-112-0/+3
| | | | | | Fix the gdbm_compat library detection logic to actually check for -lgdbm_compat independently of the ndbm detection. This fixes the build failure with `--with-dbmliborder=gdbm`, and implicit fallback to ndbm with the default value.

* gh-91851: Micro optimizations for arithmetic between Fractions (#25518)Sergey B Kirpichev2023-01-081-0/+1
| | | | | | | | Adapted from https://github.com/python/cpython/pull/24779/commits/046c84e8f9 This makes arithmetic between Fractions with small components just as fast as before python/cpython#24779, at some expense of mixed arithmetic (e.g. Fraction + int).

* gh-100690: Raise an AttributeError when the assert_ prefix is forgotten when ↵Christian Klein2023-01-061-0/+7
| | | | | | | | using Mock (#100691) Mock objects which are not unsafe will now raise an AttributeError when accessing an attribute that matches the name of an assertion but without the prefix `assert_`, e.g. accessing `called_once` instead of `assert_called_once`. This is in addition to this already happening for accessing attributes with prefixes assert, assret, asert, aseert, and assrt.
* gh-91851: Trivial optimizations in Fraction (#100791)Sergey B Kirpichev2023-01-061-0/+3

* gh-86082: bpo-41916: allow cross-compiled python to have -pthread set for ↵Dustin Spicuzza2023-01-051-0/+2
| | | | | | | CXX (#22525) When cross-compiling, the compile/run test for -pthread always fails so -pthread will never be automatically set without an override from the cache. ac_cv_pthread can already be overridden, so do the same thing for ac_cv_cxx_thread.
* gh-100562: improve performance of `pathlib.Path.absolute()` (GH-100563)Barney Gale2023-01-051-0/+3
| | | | | | | | | | | | | | | | Increase performance of the `absolute()` method by calling `os.getcwd()` directly, rather than using the `Path.cwd()` class method. This avoids constructing an extra `Path` object (and the parsing/normalization that comes with it). Decrease performance of the `cwd()` class method by calling the `Path.absolute()` method, rather than using `os.getcwd()` directly. This involves constructing an extra `Path` object. We do this to maintain a longstanding pattern where `os` functions are called from only one place, which allows them to be more readily replaced by users. As `cwd()` is generally called at most once within user programs, it's a good bargain. ```shell # before $ ./python -m timeit -s 'from pathlib import Path; p = Path("foo", "bar")' 'p.absolute()' 50000 loops, best of 5: 9.04 usec per loop # after $ ./python -m timeit -s 'from pathlib import Path; p = Path("foo", "bar")' 'p.absolute()' 50000 loops, best of 5: 5.02 usec per loop ``` Automerge-Triggered-By: GH:AlexWaygood

* gh-100146: Steal references from stack when building a list (#100147)L. A. F. Pereira2023-01-031-0/+4
| | | | | | | | | | When executing the BUILD_LIST opcode, steal the references from the stack, in a manner similar to the BUILD_TUPLE opcode. Implement this by offloading the logic to a new private API, _PyList_FromArraySteal(), that works similarly to _PyTuple_FromArraySteal(). This way, instead of performing multiple stack pointer adjustments while the list is being initialized, the stack is adjusted only once and a fast memory copy operation is performed in one fell swoop.

* gh-100228: Warn from os.fork() if other threads exist. (#100229)Gregory P. Smith2022-12-291-0/+5
| | | | | Not comprehensive, best effort warning. There are cases when threads exist on some platforms that this code cannot detect. macOS when API permissions allow and Linux with a readable /proc procfs present are the currently supported cases where a warning should show up reliably. Starting with a DeprecationWarning for now, it is less disruptive than something like RuntimeWarning and most likely to only be seen in people's CI tests - a good place to start with this messaging.
