Automatic update from web-platform-tests Support dragging JS File objects to native drop targets When a web app places a JS File object (new File([bytes], 'photo.jpg')) into a dragstart handler, the blob bytes were previously discarded in DataObject::ToWebDragData(). This CL reads the blob bytes synchronously at drag-start time using SyncedFileReaderAccumulator::Load() and passes them as a BinaryDataItem through the IPC pipeline. Platform-specific delivery to native drop targets is handled by the existing PrepareDragForFileContents() path, which is already enabled for Linux, ChromeOS, and Windows via BUILDFLAG guards in web_contents_view_aura.cc. Currently, image file types are supported via the GetSafeFilenameForImageFileContents() gate. To enable this feature, launch Chrome with: --enable-blink-features=DragAndDropJSFileObjects Bug: 41120809 Change-Id: Ibe12d867f7d01a972b7aeb6ce55660adb7300b27 Reviewed-on: https://chromium-review.googlesource.com/c/chromium/src/+/7603160 Reviewed-by: Rohan Raja <[email protected]> Reviewed-by: Kent Tamura <[email protected]> Commit-Queue: Joone Hur <[email protected]> Cr-Commit-Position: refs/heads/main@{#1627402} -- wpt-commits: 6fd907a40e68c632146df346deba6ba60299e2d5 wpt-pr: 59744
