I think you can just pass "The value of icons is not a valid list."_s

> Source/WebCore/Modules/applicationmanifest/ApplicationManifestParser.cpp:341
> +String ApplicationManifestParser::parseGenericStringInIcon(RefPtr<WTF::JSONImpl::Object> &manifest, const String& propertyName)

In C++, space should be after the ampersand

No space before the ampersand.

error: missing field 'icons' initializer [-Werror,-Wmissing-field-initializers]

[Brent Fulgham]

It looks like your patch won't compile, because the WebKit layer needs you to initialize the new 'icons' member. Can you add just that bit to _WKApplicationManifest.mm to avoid breaking the build?

The "Purpose" isn't really a property of the manifest itself, so I don't think "ApplicationManifest::Purpose" is the clearest name. What about "ApplicationManifest::IconPurpose" or "ApplicationManifest::Icon::Purpose" ?

Since this is embedded *within* ApplicationManifest, I think just calling it "ApplicationManifest::Icon" might be a better name. The full name of "ApplicationManifest::ApplicationManifestIcon" is somewhat redundant.

Is there a reason to not also update ApplicationManifest::encode() and ApplicationManifest::decode() in this patch? Those methods will need to learn about `icons` in order to send the icon information from the web process to the UI process.

I think calling it an "array" rather than "list" might be more accurate with respect to JSON terminology. (I did just check the spec and notice it uses "list" in this part of the algorithm, but maybe "array" is more familiar term to developers who might see this message.)

> Source/WebCore/Modules/applicationmanifest/ApplicationManifestParser.cpp:198

Nit: I think `const auto&` might be preferred here since you're not mutating the icons.

Should this be "src" rather than "scope"?

Can `manifest` be made const?

Why does this method take a `WTF::JSONImpl::Object` while other methods use `JSON::Object` ?

Thanks for these comments. They should all be fixed in the new patch.

Just changed "Purpose" to "IconPurpose".

I just added the `icons` to ApplicationManifest::encode() and 
ApplicationManifest::Decode.
I also added ApplicationManifest::Icon:encode() and 
ApplicationManifest::Icon::decode() because they were necessary for the 
existing functions.

Also swapped the phrasing out for "array". I did take "list" from the spec originally,
but since array is used more with JSON terminology this change makes sense.

By casting the result of `iconValue->asObject()` in `parseIcons` to 
`const JSON::Object *` I was able to get rid of the `parseGenericStringInIcon` 
function and just call `parseGenericString`.

> Source/WebCore/ChangeLog:9
> +        Tests are added to OpenSource/Tools/TestWebKitAPI/Tests/WebCore/ApplicationManifestParse.cpp

Nit: OpenSource/Tools/TestWebKitAPI/Tests/WebCore/ApplicationManifestParse **r** .cpp

> Source/WebCore/Modules/applicationmanifest/ApplicationManifestParser.cpp:207
> +            currentIcon.src = { };

Is it valid to have an icon without a src? I would guess no since the `Processing an image resource from JSON` algorithm returns failure if the input src isn't a string or fails to parse as a URL. Should this method filter out those src-less images by replacing these `.src = {}` lines with `continue;`?

> Source/WebCore/Modules/applicationmanifest/ApplicationManifestParser.cpp:223
> +                    logDeveloperWarning(makeString("The icon's src url origin of \""_s, srcURLOrigin->toString(), "\" is different from the document's origin of \""_s, documentOrigin->toString(), "\"."_s));

Is this same-origin check part of the spec? This check is specified for comparing the startURL and scope, but I don't think it needs to apply to icons.

> Source/WebKit/UIProcess/API/Cocoa/_WKApplicationManifest.h:29
> +#import <wtf/cocoa/VectorCocoa.h>

Are these necessary? Unless directly related to WTF-level code, I don't think WebKit headers meant for other clients should be importing WTF headers since it is really meant to be an implementation detail of the WebKit stack. (These, of course, would be ok in _WKApplicationManifestInternal.h if you need to define methods that work with Vector for use in other WebKit-internal code.)

> Source/WebKit/UIProcess/API/Cocoa/_WKApplicationManifest.h:61
> +@property (nonatomic, readonly) NSArray *icons WK_API_AVAILABLE(macos(WK_MAC_TBA), ios(WK_IOS_TBA));

This should be `NSArray<_WKApplicationManifestIcon *> *`. (With a `@class _WKApplicationManifestIcon;` forward declaration above)

> Source/WebKit/UIProcess/API/Cocoa/_WKApplicationManifest.h:73
> +@interface _WKApplicationManifestIcon : NSObject <NSSecureCoding>

Nit: WK_CLASS_AVAILABLE(macos(WK_MAC_TBA), ios(WK_IOS_TBA))

> Source/WebKit/UIProcess/API/Cocoa/_WKApplicationManifest.h:80
> +- (void) src:(NSURL *) srcUrl;

If these setters need to be exposed, it would be better to not include these methods explicitly, but just *not* make the properties readonly. That being said, is it actually necessary to expose these setters?

> Source/WebKit/UIProcess/API/Cocoa/_WKApplicationManifest.mm:47
> +        case _WKApplicationManifestIconPurposeMonochrome:

There are a few style checker errors here:
ERROR: Source/WebKit/UIProcess/API/Cocoa/_WKApplicationManifest.mm:47:  A case label should not be indented, but line up with its switch statement.  [whitespace/indent] [4]
ERROR: Source/WebKit/UIProcess/API/Cocoa/_WKApplicationManifest.mm:46:  Missing space before ( in switch(  [whitespace/parens] [5]

> Source/WebKit/UIProcess/API/Cocoa/_WKApplicationManifest.mm:59
> +    _WKApplicationManifestIcon *item = arrayElement;

It looks like other implementations of makeVectorElement() add an -isKindOfClass: check to filter out unexpected classes. I think this function should do the same, unless there's a reason not to here. (Generally we shouldn't assume that the array we get from the NSCoder is guaranteed to be well-formed)

> Source/WebKit/UIProcess/API/Cocoa/_WKApplicationManifest.mm:64
> +        WKPurposeToWebCorePurpose([item purpose]),

Nit: Dot syntax. item.src, item.sizes, item.type, item.purpose.

> Source/WebKit/UIProcess/API/Cocoa/_WKApplicationManifest.mm:86
> +    NSArray *icons = [aDecoder decodeObjectOfClass:[NSArray class] forKey:@"icons"];

Nit: NSArray<_WKApplicationManifestIcon *>

And I believe this should use -decodeObjectOfClasses:forKey: with NSArray *and* _WKApplicationManifestIcon, otherwise this line would only be allowed to decode an empty array. (Or an array of empty arrays, or arrays which contain empty arrays, …)

> Source/WebKit/UIProcess/API/Cocoa/_WKApplicationManifest.mm:188

Can you implement this method since you're adding it in this patch?

I'm trying to see if I can make a first patch with really just the WebCore changes

It seems like below this is the default value, so maybe this should be first in the list?

Can we make `Purpose` into a set of flags (e.g. `1 << 0`, `1 << 1`, etc.) so that we can use `OptionSet` instead?

Can we name this something more descriptive?  Maybe `manifestIcons`?  You could then have `manifestIconsArray` down below :)

NIT: `"icons"_s`
NIT: I'd also move this right above `if (!value)`

> Source/WebCore/Modules/applicationmanifest/ApplicationManifestParser.cpp:186

NIT: I'd move this one line below so it's right above `if (!arrayValue)

`iconObject`?

I think you should `const auto& iconJSON = *iconObject;` so that you don't have to keep dereferencing below

having the `continue` here means that the following line wont run, which I don't think you want/intend

in fact, you don't really `need` the `continue` at all since this is the end of the `if` chain and there's no other logic below this anyways

I think this may also need to manually delete the WebCore object too, assuming you're gonna add an ivar that holds one.

You can simplify this to just
```
    OptionSet<ApplicationManifest::Icon::Purpose> purposeAny { ApplicationManifest::Icon::Purpose::Any };
```
ditto for the others below too

Style: we prefer camelCase over snake_case in C++/ObjC :)

I'm just trying to get the changes in WebCore/Modules/applicationmanifest/* made here.
I had to add a little to the _WKApplicationManifest files to not break the build.

<Wtf/cocoa/VectorCocoa.h> is needed for the `makeVector` function
I removed <wtf/Vector.h> as it was not needed.

Are you planning on getting `_WKApplicationManifest` working next?  It would be preferable to create a bug for that work and include it in a FIXME comment where there is still work that needs to be done so that it's not forgotten.

There was already a radar for that, but I just created a bugzilla
(https://bugs.webkit.org/show_bug.cgi?id=232959) linked to the radar and will upload a
new patch here with // FIXME: https://bugs.webkit.org/show_bug.cgi?id=232959 in the
places where changes need to be made.

Just added `// FIXME: https://bugs.webkit.org/show_bug.cgi?id=232959`
where changes need to be made.

The changelog was not up to date, which I believe caused the commit bot to fail. Should be all good now.
