This fuzzer works by having aprecompiled guest program which serves as the component to run. Thisprecompiled component has a custom `fuzz.wit` which is used to interfacewith the fuzzer itself. The fuzzer is then a fuzz-generated sequence ofcommands to send to the component which verifies that everythingexecutes correctly, has no panics, etc.This fuzzer intends to stress async communication and taskinfrastructure with component-model-async. Notably this does not stresslifting/lowering or arbitrary type signatures. This does, however,permute all of the following:* Guest/host interactions (also guest/guest, host/host, etc).* Async functions, both ready and pending.* Future operations: reads, writes, cancellation, transfers, etc.* Stream operations: reads, writes, cancellation, transfers, etc.This is all throwing into a large "soup" and then asserted to workcorrectly. There's a few gotchas here and there for how this fuzzer isdesigned, such as some events requiring "yield N times to await thisevent happening". This is required because Wasmtime is allowed tonon-deterministically select between a number of "ready events" and whatto dispatch.This is not intended to be a one-size-fits-all fuzzer forcomponent-model-async. The recent enhancements to the `component_api`fuzzer are intended to complement this fuzzer in terms of what'sstressed where internally.* Review comments List of files: /wasmtime-44.0.1/crates/fuzzing/src/generators/component_async.rs Tue, 09 Dec 2025 19:32:20 +0000 Alex Crichton <alex@alexcrichton.com>
