Bug 170449

Bug #49141 is fixed and it works as designed in the latest released Safari Version 10.1 (12603.1.30.0.34) Now the issue at hand is that it has been done in a new way that matches no other browser, so you have to wait until the developers of every library updates their code to handle the new Safari, and then those new versions are deployed through every website in order to be able to use Safari.

Is there any sample page on how that is done which would works on the steps 1 I mentioned here? A stripped down working code or documentation would be nice also so I could use it on my apps also. I hope you could support the old way most sites support which would make web users more happy.

@Ryosuke: Are you still opposed to using data URLs instead of Blob URLs? Even though Blob URLs have benefits here, it is unfortunate that we do it differently than other browsers.

Actually, tineye.com does not work in WebKit, even if I switch to using Data URLs. The reason is that the page's JavaScript relies on DataTransfer.items being implemented and it is not in WebKit. JS: _onPaste: function(b) { var c = b.originalEvent && b.originalEvent.clipboardData && b.originalEvent.clipboardData.items, d = { files: [] }; c && c.length && (a.each(c, function(a, b) { var c = b.getAsFile && b.getAsFile(); c && d.files.push(c) }), this._trigger("paste", a.Event("paste", { delegatedEvent: b }), d) !== !1 && this._onAdd(b, d)) }, b.originalEvent.clipboardData.items is undefined in WebKit. So the tineye.com issue has nothing to do with the approach we chose in Bug 49141.

If you have example of sites that fail in Safari but work in Chrome because we are using Blob URLs instead of Data URLs, please let me know. It seems tineye.com is not representative of such case.

data: urls are legacy behavior that was originally implemented in Firefox. Chrome never used them and they have always used DataTransfer.items Currently Firefox also uses DataTransfer.items, although a good script that reads pasted files should try to handle both schemes because data: urls can be generated also by LibreOffice and Edge for example (I mean: tineye is not a good example, or maybe they're using UA sniffing and don't expect Webkit to paste base64) Safari should have implemented .items instead of that weird way to read a Blob

Hey guys, just one more comment and I leave this to you :) I've also issue with Gmail mail compose and Gmail integrated chat, this is its steps to reproduce: 0. Open gmail.com with a gmail account and open new email (Compose) 1. Try to paste a copied image. This works on browsers other than Safari so I have to switch to another browser just for this. Perhaps that also can be considered for the fix. Thanks

Hard to sniff GWT compiled JS of gmail but it seems a similar code with tineye available on their code: (but multiple places I see with similar code on Gmail) var b = ka("clipboardData.items", a.fe); b && (a = rc(b, function(a) { return !!a && qb(a.type, "text/html") }), b = rc(b, function(a) { return !!a && qb(a.type, "image") }), 1 == b.length && this.JI(b[0].getAsFile()), 1 == b.length && 1 == a.length && this.CJ(a[0]))

<rdar://problem/31432525>

Also GitHub, try to paste an image when you want file a bug or comment on a bug, function H(e) { if (e.clipboardData && e.clipboardData.items) { var t = Array.from(e.clipboardData.items).map(function(e) { return [e, _(e.type)] ... These are really my everyday use websites that are forcing me to use another browser just for copy pasting an image.

May I request to know the current working screenshot pasting way other than perhaps using something like hidden contenteditable? I was implementing this on my personal project http://pad.js.org and even on nightly WebKit I couldn't find a way to make this happen because as the current lack of .Items on DataTransfer, other possible solution like DataTransfer.files and DataTransfer.getData("Image/png") also didn't provide the image Blob but as Bug #49141 there should be someway for this I guess? It seems this a question for web community also https://github.com/layerssss/paste.js/issues/21

Hi, it's not at all clear for me how the new Safari handles pasting images. I can't seem to be able to extract the image from event.clipboardData (on a "paste" event). Could you point me in the right direction?

Created attachment 321620 [details] WIP patch With this patch, I can copy & paste image from Finder into Github & tineye.com. Generic copy & paste of images don't work because I'm not doing TIFF to PNG conversion yet.

Well, we need access an element in sandboxExtensions by sandboxExtensions[i] so we can't do that.

Yeah, this code isn't great. Extracted createFileFromBuffer and rewrote it like: #if PLATFORM(MAC) if (tiffWasTreatedAsPNGForWebCompatibility) { ... createFileFromBuffer(reader, imageType, reinterpret_cast<const char*>(pngData.bytes), pngData.length); return; } #endif createFileFromBuffer(reader, imageType, buffer->data(), buffer->size()); > > Source/WebCore/platform/ios/PasteboardIOS.mm:424 > > +Vector<String> Pasteboard::dataTypes() > > Perhaps this could be dataTypesForBindings, to be consistent with > readStringForBindings? So *ForBindings functions are supposed to only exist on objects that have wrappers so that we can't differentiate ones exposed to the Web versus ones only used internally. In this case, DataTransfer is the one that's exposed to the Web and Pasteboard is our internal object so we don't really want to have *ForBindings functions. Having said that, let's just rename it to dataTypesForBindings for now since this member function is not used anywhere other than DataTransfer. > > Source/WebKit/UIProcess/Cocoa/WebPasteboardProxyCocoa.mm:52 > > + auto pasteboard = PlatformPasteboard(pasteboardName); > > I don't think the local variable here adds much.

Fixed and the rest of webView declarations. However, in Objective-C, it's particularly tricky to figure out whether a given object is autorelease'd or RetainPtr'ed in Webkit although in this case we just called adoptNS so that makes it clear. > > Tools/TestWebKitAPI/Tests/WebKitCocoa/PasteImage.mm:109 > > + EXPECT_STREQ("false", [webView stringByEvaluatingJavaScript:@"dataTransfer.types.includes('image/gif').toString()"].UTF8String); > > You can EXPECT_WK_STREQ here and avoid the .UTF8String.

Obviously the last sentence assumes there is a Blob::create() overload that can handle a String rvalue-reference.

Nice catch. Fixed.

Well, this function is supposed to "consume" the shared buffer so it semantically takes the ownership of the shared buffer. That is, the semantics of these read() functions on Pasteboard*Reader classes is that it's the last thing Pasteboard code calls to hand over the contents of the shared buffer, and the buffer itself. So I'm not gonna change this code.
