Bug 1352697 is implementing a "page actions" menu (e.g. attachment 8853671 [details]). One item in the menu is the ability to share the current page. We'd like to make use of OS-supplied functionality to do this.

Bug 1360054 has the UX spec for this (https://mozilla.invisionapp.com/share/ENBBK0F9U#/screens/232626421_Explainer_-_Share).

On Windows, this is basically just bringing up the modal Windows 10 UI as shown. (For other Windows versions, the Share menu will just be hidden.)

I'm not exactly sure what API this actually is. One of these?

Jim, can you help find an owner to implement this?

So got the gecko side of this done, was wondering if there was anyone that could point me in the right direction for the windows side of it

I would like to add shareUrl() to https://github.com/mozilla/gecko-dev/blob/master/widget/windows/WindowsUIUtils.cpp, 

NS_IMETHODIMP
WindowsUIUtils::ShareUrl() 
{
// Ignore if mingw32
  ABI::Windows::ApplicationModel::DataTransfer::DataTransferManager::ShowShareUI();
  return NS_OK;
}

Now when I do that, I get :

You're not a UWP app so this is a bit more tricky than just calling that method. For one, all the UWP stuff is mirrored into win32 land a bit differently. But even then, apparently you normally need a CoreWindow instance for this particular method, which we don't have because (again) we're not a UWP app.

Fortunately, it seems some MSFT person has written a tutorial for this exact problem and this exact API. See https://blogs.msdn.microsoft.com/oldnewthing/20170315-00/?p=95735 . Hopefully that helps?

Note that we'll need to check both on the Gecko side and on the frontend side that we're actually on Win10+ (not win8 or win7 or something). For frontend, you can use AppConstant.isPlatformAndVersionAtLeast("win", "6.4"). For the C++ side, you can use IsWin10OrLater() .
Also (ugh, sorry for the triple post) - note that folks filed a few deps on the macOS bug that seem to imply we may want to pass more than just a URL. I wouldn't be surprised if you would need to ensure you provide that (e.g. window title info) here, too. It's kind of sad that the route we took in the mac bug means we have to have separate interfaces, however... it seems on Windows you would need to pass a window reference to get an hwnd from... so looks like the API needs more/different data on Windows anyway. :-(

Note that to provide actual sharing data on Windows, you can look at this blogpost: https://blogs.msdn.microsoft.com/oldnewthing/20170316-00/?p=95745 .

Full gist @ https://gist.github.com/daleharvey/c1e76edaa7abe548fd766391cfbad2f1 (I realise you didnt recommend getting the hwnd that way, was going to fix after). Also probably worth mentioning

$ grep -r "IDataTransferManagerInterop" "/c/Program Files (x86)/Windows Kits/10/include/10.0.16299.0/winrt"

is giving me nothing
Hi Jim, Gijs mentioned I should talk to you about windows related issues, I have all the firefox frontent side done and basically am just trying to call a single windows api function, ShowShareUI(). Gis pointed me to an article explaining how to do that in a win32 environment (https://blogs.msdn.microsoft.com/oldnewthing/20170315-00/?p=95735) however using that code pretty much as is @ https://gist.github.com/daleharvey/c1e76edaa7abe548fd766391cfbad2f1 gives me a compile error @ https://bugzilla.mozilla.org/show_bug.cgi?id=1363169#c9

Any chance you could point me in the right direction here, not super familiar with any of the win32 intricacies

I'm bumping this bug's priority from P4 to P3 because we've shipped 57 and the current Bugzilla prioritization regime recommends using P3 or P5 instead of P4.

The type of definition as used in https://github.com/mozilla/gecko-dev/blob/master/widget/windows/WindowsUIUtils.cpp#L62 shouldn't be necessary anymore (in fact, maybe I should file a good first bug to remove it) because we now require the windows 10 sdk to build, whereas when that code was written we "only" required the win8 sdk.

As far as I can tell the confusion is as follows:

based on:

https://blogs.msdn.microsoft.com/oldnewthing/20170316-00/?p=95745

#include <shlobj.h> // IDataTransferManagerInterop

namespace dt = ABI::Windows::ApplicationModel::DataTransfer;

using Microsoft::WRL::Wrappers::HStringReference;

WRL::ComPtr<IDataTransferManagerInterop> g_dtmInterop;
WRL::ComPtr<DT::IDataTransferManager> g_dtm;

I can only assume that IDataTransferManagerInterop isn't actually in the 'dt' namespace. I also don't see it being in a namespace in either your fallback definition or in the definition in shobjidl.h

IDataTransferManagerStatics and IDataTransferManager look like they *are* in the `dt` namespace. Or something. Does that help make things work?

> because we now require the windows 10 sdk to build,

Knowing that that was what that code was for and that its no longer needed is a huge help 

> I can only assume that IDataTransferManagerInterop isn't actually in the 'dt' namespace.

Without the <dt::IDataTransferManagerInterop> I still get "'IDataTransferManagerInterop': no GUID has been associated with this object" which seems to suggest it still doesnt find it correctly, but knowing that the .h files can be accessed I will keep on digging and see if I can figure out whats up. Seems strange that those examples are different

Cheers
So yeh this is still confusing me, I have reduced the code down to a single definition

    Microsoft::WRL::ComPtr<IDataTransferManagerInterop> dtmInterop;

I don't know, unfortunately... are you sure you have the right headers for the ComPtr stuff? Does including the headers in https://blogs.msdn.microsoft.com/oldnewthing/20030723-00/?p=43073 help?

Flags: needinfo?(mhowell)
The problem is that the definition of IDataTransferManagerInterop in shobjidl.h is wrapped in a _WIN32_WINNT version check, and we set that version to Windows 7 since that's the platform we usually need to be supporting; because of that you're only seeing a forward declaration, and trying to create pointers to an incomplete type is causing these cryptic errors. For cases like this where we're adding support for a feature that isn't in Windows 7 we sometimes copy the interface definition into our source files, and that's what I would recommend doing here rather than overriding the version define.

That should say ShObjIdl_core.h; in the 10.0.15063 SDK the version check is on line 27157, and IDataTransferManagerInterop is defined starting from line 27255.
Thanks for that Matt, so that fixed it for me, I can now get the share dialog to show however I cant seem to provide data to it

Uploaded new patch @ https://gist.github.com/daleharvey/f859f8785a1d752f82f8bd3c414c726b#file-gistfile1-txt-L184, I have the same code pretty much copy and pasted into a plain win32 app @ https://gist.github.com/daleharvey/2d9a21bdf2ed7329981ab12d08a3e5c9#file-test-cpp-L130 and I can compile and run this and it shows the relevant text in the share dialog, when I run the same code inside firefox, the callback gets called and completes (I can see the printf("Asked for data")), however the share dialog shows a loading screen then dissapears

I realise this is quite API specific but wondering if you had any ideas as I really dont know whats up from this point, Cheers
Flags: needinfo?(mhowell)
Yeah, I don't have any experience with this particular API, so my advice won't be exactly revelatory, sorry. I don't immediately see anything suspicious about your code (and it looks identical to a Raymond Chen example, which is normally a good sign). My first thought would be to log the return values from some of these calls, see if anything is giving you error codes. Since the dialog is opening first and _then_ something is going wrong, I'd probably focus on the callback to start with.
Flags: needinfo?(mhowell)
Yup I found 2 examples, both worked in the native win32 test app and neither when inside Firefox. There isnt anything different in the return values and the callback completes to return S_OK; so I dont know what could be wrong here. 

Possibly a problem being called from the wrong process, or the interaction with GetForegroundWindow() is not what I am supposed to be using but it seems like it should be working and not sure where to look now.
On recommendation from Mike I tried adding the ShareUrl method to nsDomWindowsUtils.cpp and accessing the HWND via 

    nsComPtr<nsIWidget> widget = GetWidget();
    HWND hwnd = (HWND)widget->GetNativeData(NS_NATIVE_WINDOW);

The callback code clearly works in the test code so it seems like something must be up with the context, however accessing the hwnd this way doesnt make any difference, the share dialog shows in a loading state momentarily then dissapears. So pretty stumped here, I have attached a console and see no errors being logged, callback complete fine ¯\_(ツ)_/¯
And the most recent patch (mostly cleaned up previous versions) https://gist.github.com/daleharvey/ef84258cf33fc84605617084b4fdd618, If anyone wants the domwindowutils one I can post that too
This should be part of the release notes when the feature is ready.

Will do

So I replaced CoInitializeSecurity with |return S_OK;| and everything started working so confirmed that is the problem. However the security protections are there for a reason and the only fix seems to be to remove them. 

Some suggestions have been made that we could start a new process that has open permissions and host the sharing data only, killing that process when the share is complete. That sounds safe enough but fairly complex (in my opinion as a frontend dev) for a relatively minor feature (a new process is also going to have issues interfacing with the HWND) 

Jim was wondering if 1. you knew of any feasible workaround for the permissions issue, or 2. whether the spinning of a new process was a simple thing or a bunch of risky work. Cheers

I haven't had much interaction with UWP APIs, but I'd be curious whether we can adjust what we pass into CoInitializeSecurity to make this work. Any changes would have to be specific to the parent process, however.

One suggestion that I have is to try s/RPC_C_IMP_LEVEL_IDENTIFY/RPC_C_IMP_LEVEL_IMPERSONATE/ in that call and see if you get anywhere.

Actually, I was mistaken on that. The docs state that RPC_C_IMP_LEVEL_DEFAULT is not a valid option for CoInitializeSecurity. While that may allow you to finish working on your patch, I'd rather that we didn't land a change that uses a flag that we're explicitly not supposed to be using.

Further exploration might be in order here.
Ok Aaron, yeh the patch is working for now, although seemed to cause problems in debug mode but either way can finish it up as is then look at fixing the coinitialise

So my string problem wasnt actually a conversion problem, it looks like the strings are getting GC'd or something before the callback runs - https://gist.github.com/daleharvey/9a9f29969a58c191edc0ceda0df841ff
Even capturing values corrupts once inside the callback context - https://gist.github.com/daleharvey/36cc005ea5aa91e9d13c5cbf0992a78f, I figure there must be a way to define callback paramters, but having problems figuring it out
ok! got some help and figured out the above problem, was simply a change from a & to a = to have the callback reference by value. Now all that works just need to get the share to accept the Uri, getting a surprising compile error for 

  ABI::Windows::Foundation::Uri link = new ABI::Windows::Foundation::Uri(url);

Which is weird since I think I am including all the headers, but going on what this bug has been like so far probably something silly is wrong
So fairly sure I need a forward declaration again here, I tried copying https://gist.github.com/daleharvey/ee771dceae8256a32ef0af89f93fdb5d over from windows.applicationmodel.h but looks like it needs more (pasted the error in that gist)

Matt hopefully the last question about this, do you know what I need to be able to use Uri here? Thanks
Flags: needinfo?(mhowell)
There's definitely a definition for Windows.Foundation.Uri in windows.foundation.idl, but I can't find it in the windows.foundation.h header which was supposedly generated from that. I would definitely try including windows.foundation.h if you haven't already though.

I did find https://msdn.microsoft.com/en-us/library/hh973459.aspx which seems to indicate it might not be possible to construct a Uri object directly like that, you might have to go through this IUriRuntimeClassFactory thing.

I also found a page (https://docs.microsoft.com/en-us/windows/uwp/cpp-and-winrt-apis/interop-winrt-abi) which has some info about how this WinRT stuff works in C++, so some of that might help to understand what's going on if you haven't seen it yet.

Updated working patch
Attachment #8980217 - Attachment is obsolete: true
Thanks Matt that was a huge help.

This is a working patch, however as Aaron pointed out RPC_C_IMP_LEVEL_DEFAULT isnt a valid param for that and I need to disable the result assertions or it crashes in debug mode. None of the other values allow us to access the params when doing a share so we need a solution for that, either to relax the permissions / not call CoInitializeSecurity on the parent process, or to spin off a new process with relaxed permissions. 

Either options would be touching sensitive platform code I dont have much background on so would definitely need guidance to carry on at this point.

Aaron what do you think are the options here?
Flags: needinfo?(aklotz)
Attached patch SetNegotiableSecurityOnProxy (obsolete) — Splinter Review
Removing CoInitializeSecurity is not an option, unfortunately.

My first suggestion is based on the fact that CoInitializeSecurity establishes the baseline COM security configuration for the entire process. However, the security configuration can also be set on a per-proxy basis.

I am attaching a patch that adds a function called SetNegotiableSecurityOnProxy to mozilla/mscom/Utils.h. Try calling this for each of your dtm and dtmInterop interfaces, and see if it helps. If it does, I'll file a dependent bug and land it in MSCOM.

If that doesn't work, I suggest we follow up on the Microsoft developers' comments about needing CoInitializeSecurity to be "AppContainer-aware" to find out what they actually mean by that. Maybe there's a canonical security configuration there that we should be using.

To clarify: You should call SetNegotiableSecurityOnProxy as soon as you have the interface, before you do anything else with it.
I made a mistake in the first cut of the patch. Here is a corrected revision.

Doh thanks, should have realised as I have had to .Get() to fix things a bunch of times here. The patch however didnt work, updated with my current version, will ask if there is anything about that App-Container aware comment on the mailing list.
Got a hint from the mailing list, it seems like explorer.exe has the same problems and they use https://gist.github.com/daleharvey/4e3d04ff7705301abdae6b6d98788c8c to fix it, that code doesnt compile for us (we dont have access to wil/resources.h?), trying to convert it to something that works for us but again not familiar with this code at all so if anyone was able to help out that would be great
The wil::unique_any thing looks like it's just a smart pointer? If so then we should be able to substitute a mozilla::UniquePtr, passing it a deleter that calls LocalFree. I don't see anything else in that gist that looks nonstandard.
I'm not a fan of SDDL strings in our code, as they're too cryptic for my liking.

But it is easy enough to translate that string into code that works with our existing security descriptor setup.

However with my last update after our builds switched to clang and I had to update my SDK this no longer runs for me, code compiles fine however the share UI doesnt display at all, no errors on both debug and obj builds, I tried checking if the IDataTransferManagerInterop definition changed in the 134 SDK but its the same guid so I have no idea whats up here

It looks to me like you're leaking these HSTRINGs. To fix this, I would suggest using UniquePtr with a custom deleter that calls WindowsDeleteString, that way the compiler will be able to clean these up when you return early from failed return codes.

Use CertStoreUniquePtr [1] and CertStoreDeleter [2] as an example of how to do this:

The closure is trying to capture |title| by copying it. Based on what I see in your code, you want to std::move it into the closure. For example, https://searchfox.org/mozilla-central/rev/ce57be88b8aa2ad03ace1b9684cd6c361be5109f/widget/windows/JumpListBuilder.cpp#259

Add result checking in here too, please. Probably the best pattern to use here, since you're returning an HRESULT, is:

Yup, I copied the just return NS_OK from the function above, there is no UX for the failure path and doesnt look to be any reason it should fail. Seems like something if we get reports about we could improve if needed.

argh sorry, neither SetWebLink nor SetApplicationLink are members of IDataPackage

*error: no member names 'SetApplicationLink in 'ABI::Windows::ApplicationModel::DataTransfer::IDataPackage'*

Looks like they are in IDataPackage2, but thats not what |spDataRequest->get_Data(| returns and I cant see how to get it, Aaron do you have a pointer here?
Flags: needinfo?(dharvey) → needinfo?(aklotz)
Call QueryInterface on your IDataPackage to resolve the IDataPackage2.
