ASSERTION FAILED: ASSERT(!containsImage \|\| MIMETypeRegistry::isSupportedImageResourceMIMEType([resource MIMEType])) in -[NSPasteboard(WebExtras) _web_writePromisedRTFDFromArchive:containsImage:] https://bugs.webkit.org/show_bug.cgi?id=184161 <rdar://problem/39051645> Reviewed by Dan Bernstein. .: * ManualTests/DragInlinePDFImageDocument.html: Added. * ManualTests/resources/simple.pdf: Added. Source/WebKitLegacy/mac: Fixes an assertion failure when quitting an app that uses a Legacy WebKit web view after dragging-and- dropping a PDF embedded using an HTML image element into the same web view. When performing a drag-and-drop of a PDF document image (WebCore::PDFDocumentImage) we create a WebArchive from the main frame's WebHTMLView and promise AppKit that we will provide a Rich Text Format (RTF) document from this archive if needed. For some reason, on app termination AppKit requests that the WebHTMLView fulfill its RTF document promise for the WebArchive created at the start of the drag operation. To do this, we need to extract the image resource from the Web Archive. Currently we query MIMETypeRegistry::isSupportedImageResourceMIMEType() to see if the contained image is one that we can handle. However MIMETypeRegistry::isSupportedImageResourceMIMEType() only returns true if WebKit supports creating an image document for the specified MIME type. Disregarding the iOS motivated setting Settings::useImageDocumentForSubframePDF, PDFs and PostScripts do not create an image document when navigated to directly. Since we can support dragging PDF document images we need to query if MIMETypeRegistry::isPDFOrPostScriptMIMEType() in addition to querying MIMETypeRegistry::isSupportedImageResourceMIMEType(). We need to do both such queries before falling back to using the main resource of the Web Archive as the image. Otherwise, we will cause an assertion failure if the main resource of the Web Archive is not an image document. * Misc/WebNSPasteboardExtras.mm: (-[NSPasteboard _web_writePromisedRTFDFromArchive:containsImage:]): Canonical link: https://commits.webkit.org/200530@main git-svn-id: https://svn.webkit.org/repository/webkit/trunk@231061 268f45cc-cd09-0410-ab3c-d52691b4dbfc 2018-04-26 18:46:42 +00:00			`<!DOCTYPE html>`
