* gh-127629: Add ctypes to the Emscripten build (#127683)Hood Chatham2024-12-101-0/+1
| | | Adds tooling to build libffi and add ctypes to the stdlib for Emscripten.
* gh-127637: add tests for `dis` command-line interface (#127759)Bénédikt Tran2024-12-091-0/+1

* gh-126925: Modify how iOS test results are gathered (#127592)Russell Keith-Magee2024-12-092-0/+4
| | | | | | | Adds a `use_system_log` config item to enable stdout/stderr redirection for Apple platforms. This log streaming is then used by a new iOS test runner script, allowing the display of test suite output at runtime. The iOS test runner script can be used by any Python project, not just the CPython test suite.

* GH-127090: Fix `urllib.response.addinfourl.url` value for opened `file:` ↵Barney Gale2024-12-071-0/+3
| | | | | URIs (#127091) The canonical `file:` URL (as generated by `pathname2url()`) is now used as the `url` attribute of the returned `addinfourl` object. The `addinfourl.url` attribute reflects the resolved URL for both `file:` or `http[s]:` URLs now.

* gh-120010: Fix invalid (nan+nanj) results in _Py_c_prod() (GH-120287)Sergey B Kirpichev2024-12-061-0/+2
| | | | | | | | | | | | | | | | | | | | In some cases, previously computed as (nan+nanj), we could recover meaningful component values in the result, see e.g. the C11, Annex G.5.1, routine _Cmultd(): >>> z = 1e300+1j >>> z*(nan+infj) # was (nan+nanj) (-inf+infj) That also fix some complex powers for small integer exponents, computed with optimized algorithm (by squaring): >>> z**5 # was (nan+nanj) Traceback (most recent call last): File "<python-input-1>", line 1, in <module> z**5 ~^^~ OverflowError: complex exponentiation

* GH-125413: Revert addition of `pathlib.Path.scandir()` method (#127377)Barney Gale2024-12-052-1/+4
| | | | | | | | | | Remove documentation for `pathlib.Path.scandir()`, and rename the method to `_scandir()`. In the private pathlib ABCs, make `iterdir()` abstract and call it from `_scandir()`. It's not worthwhile to add this method at the moment - see discussion: https://discuss.python.org/t/ergonomics-of-new-pathlib-path-scandir/71721 Co-authored-by: Steve Dower <steve.dower@microsoft.com>
* gh-127582: Make object resurrection thread-safe for free threading. (GH-127612)Sam Gross2024-12-051-0/+2
| | | | | | | | | | | | Objects may be temporarily "resurrected" in destructors when calling finalizers or watcher callbacks. We previously undid the resurrection by decrementing the reference count using `Py_SET_REFCNT`. This was not thread-safe because other threads might be accessing the object (modifying its reference count) if it was exposed by the finalizer, watcher callback, or temporarily accessed by a racy dictionary or list access. This adds internal-only thread-safe functions for temporary object resurrection during destructors.

| | | | | | | | | | | | | | | | | (GH-127331) - Add `git describe` output to headers generated by `make_ssl_data.py` This info is more important than the date when the file was generated. It does mean that the tool now requires a Git checkout of OpenSSL, not for example a release tarball. - Regenerate the older file to add the info. To the other older file, add a note about manual edits. - Add notes on how to add a new OpenSSL version - Add 3.4 error messages and multissl tests

* gh-69639: Add mixed-mode rules for complex arithmetic (C-like) (GH-124829)Sergey B Kirpichev2024-11-261-0/+2
| | | | | | | | | | | | | | | "Generally, mixed-mode arithmetic combining real and complex variables should be performed directly, not by first coercing the real to complex, lest the sign of zero be rendered uninformative; the same goes for combinations of pure imaginary quantities with complex variables." (c) Kahan, W: Branch cuts for complex elementary functions. This patch implements mixed-mode arithmetic rules, combining real and complex variables as specified by C standards since C99 (in particular, there is no special version for the true division with real lhs operand). Most C compilers implementing C99+ Annex G have only these special rules (without support for imaginary type, which is going to be deprecated in C2y).

* GH-127236: `pathname2url()`: generate RFC 1738 URL for absolute POSIX path ↵Barney Gale2024-11-251-0/+5
| | | | | | | | | | | | | | | (#127194) When handed an absolute Windows path such as `C:\foo` or `//server/share`, the `urllib.request.pathname2url()` function returns a URL with an authority section, such as `///C:/foo` or `//server/share` (or before GH-126205, `////server/share`). Only the `file:` prefix is omitted. But when handed an absolute POSIX path such as `/etc/hosts`, or a Windows path of the same form (rooted but lacking a drive), the function returns a URL without an authority section, such as `/etc/hosts`. This patch corrects the discrepancy by adding a `//` prefix before drive-less, rooted paths when generating URLs.
