Hood Chatham	bbe589f93c	gh-133600: Move config.site-wasm32-emscripten into the emscripten folder (#136934) ... Reorganises the large Emscripten-specific file into the Emscripten folder.	2025-07-22 07:58:31 +08:00
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

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
