* gh-114685: Fix incorrect use of PyBUF_READ in import.c (GH-114686)Nikita Sobolev2024-01-291-1/+1

* gh-109653: Improve import time of importlib.metadata / email.utils (#114664)Shantanu2024-01-293-2/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | My criterion for delayed imports is that they're only worth it if the majority of users of the module would benefit from it, otherwise you're just moving latency around unpredictably. mktime_tz is not used anywhere in the standard library and grep.app indicates it's not got much use in the ecosystem either. Distribution.files is not nearly as widely used as other importlib.metadata APIs, so we defer the csv import. Before: ``` λ hyperfine -w 8 './python -c "import importlib.metadata"' Benchmark 1: ./python -c "import importlib.metadata" Time (mean ± σ): 65.1 ms ± 0.5 ms [User: 55.3 ms, System: 9.8 ms] Range (min … max): 64.4 ms … 66.4 ms 44 runs ``` After: ``` λ hyperfine -w 8 './python -c "import importlib.metadata"' Benchmark 1: ./python -c "import importlib.metadata" Time (mean ± σ): 62.0 ms ± 0.3 ms [User: 52.5 ms, System: 9.6 ms] Range (min … max): 61.3 ms … 62.8 ms 46 runs ``` for about a 3ms saving with warm disk cache, maybe 7-11ms with cold disk cache.

* GH-113464: A JIT backend for tier 2 (GH-113465)Brandt Bucher2024-01-290-0/+0
| | | | | | | | Add an option (--enable-experimental-jit for configure-based builds or --experimental-jit for PCbuild-based ones) to build an *experimental* just-in-time compiler, based on copy-and-patch (https://fredrikbk.com/publications/copy-and-patch.pdf). See Tools/jit/README.md for more information, including how to install the required build-time tooling. Merry JIT-mas! ;)

* Use bool in fileinput.input() docstring and tests for the inplace argument ↵Ville Skyttä2024-01-272-3/+3
| | | | | (GH-111998) The `.rst` docs, most tests, and typeshed already use bool for it.
* GH-79634: Speed up pathlib globbing by removing `joinpath()` call. (#114623)Barney Gale2024-01-273-5/+6
| | | | | Remove `self.joinpath('')` call that should have been removed in 6313cdde. This makes `PathBase.glob('')` yield itself *without* adding a trailing slash. It's hard to say whether this is more or less correct, but at least everything else is faster, and there's no behaviour change in the public classes where empty glob patterns are disallowed.

* gh-113055: Use pointer for interp->obmalloc state (gh-113412)Neil Schemenauer2024-01-279-24/+157
| | | | | | | | | For interpreters that share state with the main interpreter, this points to the same static memory structure. For interpreters with their own obmalloc state, it is heap allocated. Add free_obmalloc_arenas() which will free the obmalloc arenas and radix tree structures for interpreters with their own obmalloc state. Co-authored-by: Eric Snow <ericsnowcurrently@gmail.com>
* Cover OS-specific behaviour in `PurePathBase` and `PathBase` tests. (#114633)Barney Gale2024-01-272-627/+625

| | | | | | | | Add `@needs_symlinks` decorator for tests that require symlink support in the path class. Also add `@needs_windows` and `@needs_posix` decorators for tests that require a specific a specific path flavour. These aren't much used yet, but will be later.

* GH-73435: Add `pathlib.PurePath.full_match()` (#114350)Barney Gale2024-01-266-72/+155
| | | | | | | | | | | | | | | | In 49f90ba we added support for the recursive wildcard `**` in `pathlib.PurePath.match()`. This should allow arbitrary prefix and suffix matching, like `p.match('foo/**')` or `p.match('**/foo')`, but there's a problem: for relative patterns only, `match()` implicitly inserts a `**` token on the left hand side, causing all patterns to match from the right. As a result, it's impossible to match relative patterns from the left: `PurePath('foo/bar').match('bar/**')` is true! This commit reverts the changes to `match()`, and instead adds a new `full_match()` method that: - Allows empty patterns - Supports the recursive wildcard `**` - Matches the *entire* path when given a relative pattern
