| | | | | | | | | | * gh-98925: Lower marshal recursion depth for WASI (GH-98938) For wasmtime 2.0, the stack depth cost is 6% higher. This causes the default max `marshal` recursion depth to blow the stack. As the default marshal depth is 2000 and Windows is set to 1000, split the difference and choose 1500 for WASI to be safe.

* gh-96387: take_gil() resets drop request before exit (#96869) (#96941)Victor Stinner2022-09-201-0/+11
| | | | | | | | | | | | | | | At Python exit, sometimes a thread holding the GIL can wait forever for a thread (usually a daemon thread) which requested to drop the GIL, whereas the thread already exited. To fix the race condition, the thread which requested the GIL drop now resets its request before exiting. take_gil() now calls RESET_GIL_DROP_REQUEST() before PyThread_exit_thread() if it called SET_GIL_DROP_REQUEST to fix a race condition with drop_gil(). Issue discovered and analyzed by Mingliang ZHAO. (cherry picked from commit 04f4977f508583954ad7b9cb09076ee1e57461f8)

* [3.11] gh-95853: Add script to automate WASM build (GH-95828, GH-95985, ↵Christian Heimes2022-09-131-3/+7
| | | | | | | | | | | | GH-96045, GH-96389, GH-96744) (GH-96749) Automate WASM build with a new Python script. The script provides several build profiles with configure flags for Emscripten flavors and WASI. The script can detect and use Emscripten SDK and WASI SDK from default locations or env vars. ``configure`` now detects Node arguments and creates HOSTRUNNER arguments for Node 16. It also sets correct arguments for ``wasm64-emscripten``.

| | | | | | | | | | | | | | | (GH-94999) (GH-95353) When keyword argument name is an instance of a str subclass with overloaded methods __eq__ and __hash__, the former code could not find the name of an extraneous keyword argument to report an error, and _PyArg_UnpackKeywords() returned success without setting the corresponding cell in the linearized arguments array. But since the number of expected initialized cells is determined as the total number of passed arguments, this lead to reading NULL as a keyword parameter value, that caused SystemError or crash or other undesired behavior.
