Automatic update from web-platform-tests NativeIO: Plumbing and minimal functionality. This is a scaffolding CL for NativeIO, a.k.a. Low-Level Storage. Most details will probably change over time, but the overall architecture is intended to be stable. To facilitate review, this CL aims to introduce enough aspects of the API for readers to reason about IPC security and general architectural concerns in the browser and in Blink. The summary below is also intended to facilitate review. * NativeIO introduces new per-origin storage. The per-origin model matches other existing storage APIs, so no new permissions are added. * NativeIO storage is structured as files in a flat per-origin namespace. Files are stored in a per-origin directory under the user's profile. * The browser-side implementation enforces access control at the file level. Once a renderer is allowed to open a file, the browser passes the file descriptor to the renderer. This approach aims to minimize the latency of I/O operations. * The renderer exposes two API flavors to web pages -- an asynchronous version and a synchronous version. The latter is only available in dedicated workers. The goal is to allow developers to experiment with both flavors of the API, and report back on performance and stability. * In the asynchronous API, all file I/O is done on tasks posted to Blink's worker thread pool. This avoids jank on the main thread, at the cost of two thread hops per I/O operation. This CL adds two READMEs with some minimal information. * //third_party/blink/renderer/modules/native_io/README.md * //third_party/blink/web_tests/external/wpt/native-io/README.md An API explainer is available at https://github.com/fivedots/nativeio-explainer Binary-Size: New Web Platform feature.
