            How do I enable Feature/Permissions Policy in an iframe in Google Add-ons?
            Asked 2021-Jun-09 at 18:03

            I am trying use a feature policy, serial, in my google add-on. I am having difficulty trying to enable this particular feature policy inside an iframe, mainly I believe is because the parent iframes don't have it enabled. Below is what the iframe DOM tree looks like. I don't have access to "sandboxFrame" and "userHtmlFrame" directly, so I cannot change its allowed features. Even if I set 'serial' in the most child iframe, I cannot find the 'serial' feature enabled in its featurePolicy.

            ...

            1. Yes, you can pass any permission into nested iframe only if parent context has that permission granted.
              Keep in mind that when passing permissions the origin will be changed accordingly, i.e:

            </code><br> <code> // the permission for fullscreen is 'self' (== http://example.com)</code><br> <code> // but main thing is this is that iframe HAS that permission, therefore</code><br> <code> // it can grant it to any nested context with ANY origin:</code><br> <code> <iframe src='https://www.youtube.com' allow="fullscreen https://www.youtube.com"></code><br> <code> // will get permission of fullscreen mode for https://www.youtube.com origin</code><br> <code>

            1. In the parent iframe the serial Feature Policy directive is not specified in the allow='...' attribute. That means this feature is allowed with the default value - 'src'. Therefore parent iframe has implicitly permission for serial, so it can pass it into any nested iframe.

            2. I hear nothing about the serial Feature Policy directive, is it supported?

            IDirectMusicPerformance8 - MIDI only, or WAV?
            Asked 2021-Jun-07 at 19:14

            I'm trying to work with an old version of DirectX (8.1) and I'm finding the documentation more than a little confusing. It feels like the IDirectMusicPerformance8 interface is for MIDI playback, as it has various MIDI-related methods on it, but various parts of the documentation suggest that it can be used to play back WAV data as well. For instance, the tutorial says that you call InitAudio on the performance, and it states "Wave files require only a single performance channel, and MIDI files require up to 16".

            So is it for MIDI or can it be used for WAV?

            If it can be used for WAV, I'm even more stumped, because I'm initializing it, running performance->PlaySegment(segment, 0, 0, NULL), getting a success response, but the audio is silent.

            Answered 2021-Jun-07 at 19:14

            OK, I figured it out. Apparently I had been using IDirectMusicPerformance instead of IDirectMusicPerformance8, which I guess is some kind of old compatibility thing that is missing various new DirectX 8.1 methods. Once I switched to that (along with the associated '8' versions of the loader and segment interfaces), used their new InitAudio and LoadObjectFromFile methods, called segment->Download(performance) before playing, then played with the new PlaySegmentEx method, it worked and played the WAV.

            Geolocation denied for HTML embedded site - anchor tag feature policy
            Asked 2021-Jun-04 at 11:02

            The iframe with allow="geolocation" works great. But what if I want to load a link which calls getCurrentPosition() from a html anchor tag?

            Example : In iframe, I'll use

            I have a use case where a html embed link like

            Click here to get geolocation

            is embedded in a parent site. The parent site loads the child link inside it's own iframe

            It is to be noted that The parent site's iframe has the allow="geolocation" attribute .

            In this case the request is silently denied with error

            errorCode :1

            errorMessage: "Geolocation has been disabled in this document by permissions policy."

            The feature policy document point to iframe but what about anchor tag embeds?

            I understand that I can use a iframe instead of anchor tag embed but the parent site only allows anchor tag's.

            PS - This is my first question here. Please assist.

            Note :

            1. I also tried a random shot by including allow="geolocation" for anchor tag, but it doesn't work.
            2. This seems to work on Safari (which I'm assuming is because Safari hasn't yet implemented feature policy for cross origin site requests)

            Edit 1 :

            I tried my use case in jsfiddle and notice that all scripts i give (iframe or anchor tag) are loaded inside jsfiddle's iframe

            If i load my iframe inside this, it works perfectly !(perfectly balanced, as all things should be...)

            But if I load my anchor tag inside this, i get the error. As per granty's answer

            the jsfiddle's iframe with allow='geolocation' should set jsfiddle site's feature policy that all scripts loaded inside that iframe can access geolocation right ? Why does my iframe inside jsfiddle's iframe work but anchor tag doesnt ?

            Note - I have no control over the top level site. I only code the scripts for https://siteWhichCallsGetGeolocation.com

            SOLUTION (if you have control over top document's feature policy or control over any intermediate </code> which have geolocation permission)</strong> (derived from granty's answer)</p> <p>I tried the suggested solution by changing the jsfiddle's iframe attribute via inspect element to</p> <p><code><iframe name="result" allow="midi; geolocation https://siteWhichCallsGetGeolocation.com ; microphone; camera; display-capture; encrypted-media;" sandbox="allow-modals allow-forms allow-scripts allow-same-origin allow-popups allow-top-navigation-by-user-activation allow-downloads" allowfullscreen="" allowpaymentrequest="" frameborder="0">

            To highlight, I added my site next to geolocation in allowlist like

            allow="midi; geolocation https://siteWhichCallsGetGeolocation.com ;

            and then loaded my anchor tag. When the getCurrentPosition() was triggered from script loaded from https://siteWhichCallsGetGeolocation.com, I got the browser prompt to Allow/Deny location sharing. I allowed and got the coordinates!

            Wow! If only it could be as simple as editing the top level document's feature/permissions policy via inspect element.

            But alas,I have no control over the top level document's feature policy. At least I understood what's going on under the hood.

            Answered 2021-May-30 at 09:48

            A segmentation fault happens when the code try to access a memory region that is not available.

            Accessing an array out of bounds doesn't means that the memory before or after the area occupied by the array is not available: The compiler or the runtime usually put all varibales or data in general in a given block of memory. If your array is the last item of such a memory block, the accessing it with a to big index will produce a Segmentaion Fault but is the array is in the middle of the memory block, you will just access memory used for other data, giving unexpected result and undefined behavior.

            If the array (In may example, but valid for anything) is written, accessing available memory will not produce a segmentation fault but will overwrite something else. It may produce unexpected results or crash or segmentation fault later! This kind of bug is frequently very difficult to find because the unexpected result/behavior looks completely independent of the root cause.

            Sketch.cpp is compiled as as C++, including test.h. In order to support function overloading, class membership etc, C++ uses name mangling to encode these C++ features in the symbol name. As such the symbol name for some_test in Sketch.cpp is not the same as that in test.c which is compiled as C and no name mabgling is applied..

            The solution is to prevent name mangling for this symbol when the header is C++ compiled by specifying that the symbol has C linkage:
