Serhiy Storchaka	3a89dfe32b	Revert "gh-112068: C API: Add support of nullable arguments in PyArg_Parse (GH-121303)" (#136991)	2025-07-22 16:39:50 +03:00
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

Sam Gross	f2379535fe	gh-133164: Add PyUnstable_Object_IsUniqueReferencedTemporary C API (gh-133170) ... After gh-130704, the interpreter replaces some uses of `LOAD_FAST` with `LOAD_FAST_BORROW` which avoid incref/decrefs by "borrowing" references on the interpreter stack when the bytecode compiler can determine that it's safe. This change broke some checks in C API extensions that relied on `Py_REFCNT()` of `1` to determine if it's safe to modify an object in-place. Objects may have a reference count of one, but still be referenced further up the interpreter stack due to borrowing of references. This provides a replacement function for those checks. `PyUnstable_Object_IsUniqueReferencedTemporary` is more conservative: it checks that the object has a reference count of one and that it exists as a unique strong reference in the interpreter's stack of temporary variables in the top most frame.
