Hood Chatham	c933a6bb32	gh-124621: Emscripten: Support pyrepl in browser (GH-136931) ... Basic support for pyrepl in Emscripten. Limitations: * requires JSPI * no signal handling implemented As followup work, it would be nice to implement a webworker variant for when JSPI is not available and proper signal handling. Because it requires JSPI, it doesn't work in Safari. Firefox requires setting an experimental flag. All the Chromiums have full support since May. Until we make it work without JSPI, let's keep the original web_example around. Co-authored-by: Łukasz Langa <lukasz@langa.pl> Co-authored-by: Éric <merwok@netwok.org>	2025-07-22 12:13:38 +02:00

Malcolm Smith	149bddcc21	gh-131531: Android test fixes (#136845) ... Modifies the test runner script to no longer export the the HOST environment variable, and to allow for tests that produce no Python output (output from the Android console is still expected and required). These changes stem from knowledge gained during developing a PR for Android support in cibuildwheel.	2025-07-22 14:51:16 +08:00
Jelle Zijlstra	46cbdf967a	gh-135228: When @dataclass(slots=True) replaces a dataclass, make the original class collectible (#136893) ... An interesting hack, but more localized in scope than #135230. This may be a breaking change if people intentionally keep the original class around when using `@dataclass(slots=True)`, and then use `__dict__` or `__weakref__` on the original class.

Nathan Goldbaum	89c220b93c	gh-133296: Publicly expose critical section API that accepts PyMutex (gh-135899) ... This makes the following APIs public: * `Py_BEGIN_CRITICAL_SECTION_MUTEX(mutex),` * `Py_BEGIN_CRITICAL_SECTION2_MUTEX(mutex1, mutex2)` * `void PyCriticalSection_BeginMutex(PyCriticalSection *c, PyMutex *mutex)` * `void PyCriticalSection2_BeginMutex(PyCriticalSection2 *c, PyMutex *mutex1, PyMutex *mutex2)` The macros are identical to the corresponding `Py_BEGIN_CRITICAL_SECTION` and `Py_BEGIN_CRITICAL_SECTION2` macros (e.g., they include braces), but they accept a `PyMutex` instead of an object. The new macros are still paired with the existing END macros (`Py_END_CRITICAL_SECTION`, `Py_END_CRITICAL_SECTION2`).	2025-07-21 17:25:43 -04:00
Kumar Aditya	f183996eb7	gh-136870: fix data race in PyThreadState_Clear on sys_tracing_threads (#136951) ... In free-threading, multiple threads can be cleared concurrently as such the modifications on `sys_tracing_threads` should be done while holding the profile lock, otherwise it can race with other threads setting up profiling.	2025-07-21 20:35:25 +00:00

Peter Bierma	a10960699a	gh-136421: Load _datetime static types during interpreter initialization (GH-136583) ... `_datetime` is a special module, because it's the only non-builtin C extension that contains static types. As such, it would initialize static types in the module's execution function, which can run concurrently. Since static type initialization is not thread-safe, this caused crashes. This fixes it by moving the initialization of `_datetime`'s static types to interpreter startup (where all other static types are initialized), which is already properly protected through other locks.	2025-07-21 13:47:26 -04:00
Barney Gale	80b2d60a51	GH-136874: url2pathname(): discard query and fragment components (#136875) ... In `urllib.request.url2pathname()`, ignore any query or fragment components in the given URL.	2025-07-21 17:33:20 +00:00

Alper	65893c6f9c	gh-116738: Make syslog module thread-safe (#136760) ... Make the setlogmask() function in the syslog module thread-safe. These changes are relevant for scenarios where the GIL is disabled or when using subinterpreters.	2025-07-21 09:24:42 -07:00

Mikhail Efimov	58d305cf38	gh-136438: Make sure test_generated_cases pass with all optimization levels (#136594) ... Fix the `test_generated_cases` to work with `-O` or `-OO` flags. Previously, `test_generated_cases` was catching an `AssertionError` while `Tools/cases_generator/optimizer_generator.py` used an `assert` statement. This approach semantically incorrect, no one should trying to catch an `AssertionError`! Now the `assert` statement has been replaced with an explicit `raise ValueError(...)` and the corresponding `self.assertRaisesRegex(AssertionError, ...)` has been updated to catch a `ValueError` instead.	2025-07-21 15:25:25 +03:00

UUIDv8 has been added in Python 3.14.0a2 and its construction time has been improved in Python 3.14.0a4, but since those changes will not be visible when comparing the latest Python 3.13 and 3.14 together, we do not document them on the What's New page to avoid confusion.	2025-07-21 08:23:16 +00:00

Bénédikt Tran	4a151cae33	gh-134531: prefer using _hashlib module state instead of module object (#136865) ... Some internal helper functions taking the module object to retrieve its state under some conditions now directly take the module's state instead as those conditions hold most of the time.	2025-07-20 13:10:36 +00:00

Hood Chatham	7ae4749d06	gh-124621: Emscripten: Add support for async input devices (GH-136822) ... This is useful for implementing proper `input()`. It requires the JavaScript engine to support the wasm JSPI spec which is now stage 4. It is supported on Chrome since version 137 and on Firefox and node behind a flag. We override the `__wasi_fd_read()` syscall with our own variant that checks for a readAsync operation. If it has it, we use our own async variant of `fd_read()`, otherwise we use the original `fd_read()`. We also add a variant of `FS.createDevice()` called `FS.createAsyncInputDevice()`. Finally, if JSPI is available, we wrap the `main()` symbol with `WebAssembly.promising()` so that we can stack switch from `fd_read()`. If JSPI is not available, attempting to read from an AsyncInputDevice will raise an `OSError`.	2025-07-19 17:14:29 +02:00
