When an exception is thrown during the processing of streaming WebAssembly, `op_wasm_streaming_abort` is called. This op calls into V8, which synchronously rejects the promise and calls into the promise rejection handler, if applicable. But calling an op borrows the isolate's `JsRuntimeState` for the duration of the op, which means it is borrowed when V8 calls into `promise_reject_callback`, which tries to borrow it again, panicking. This change changes `op_wasm_streaming_abort` from an op to a binding (`Deno.core.abortWasmStreaming`). Although that binding must borrow the `JsRuntimeState` in order to access the `WasmStreamingResource` stored in the `OpTable`, it also takes ownership of that `WasmStreamingResource` instance, which means it can drop any borrows of the `JsRuntimeState` before calling into V8. |
