This is a temporary number since it's probably won't make it into these releases.

Ditto.

Needs API review and an ObjC equivalent.

We should probably not include this function because there is no language concept for a HasOwnProperty operation that takes a key. Instead, the language has an 'in' operator and a hasOwnProperty built-in function, and both take string arguments.

Clients who want JSObjectHasPropertyWithKey can use JSObjectGetPropertyWithKey, or build a helper function on top of it.

I believe that these APIs duplicate the APIs listed under @interface JSValue (SubscriptSupport), but in a less powerful way.

Perhaps we should consider adding just a deletePropertyForKeyedSubscript: method.

That's not true for example: 

Symbol.iterator in []
evaluates to true.

Object.hasOwnProperty(Symbol.iterator, [])
evaluates to false (Symbol.iterator is on Array.prototype).

{ toString() { return "length"; } } in []
evaluates to true.

Object.hasOwnProperty({ toString() { return "length"; } }, [])
evaluates to true.

I'm not sure I really understand the implications of this. Could you explain what you mean further?

What does adding a deletePropertyForKeyedSubscript mean. How would you invoke it? How does it work?

[Geoffrey Garen]

I didn't notice at first that this patch was exclusively about ToPropertyKey.

Let me step back a minute and look at where we are in trunk.

JavaScript provides these operations for get/set/has/remove:

    {Get|Set|Has|Remove}ById
        Example: o.id
    {Get|Set|Has|Remove}ByValue
        Example: o[value]
    {Get|Set|Has|Remove}ByPropertyKey [ new in ES6 ]
        Example: Reflect.get([], Symbol.iterator)

The C API currently has:

    {Get|Set|Has|Remove}ById
        JSObjectGetProperty (et al)
    {Get|Set|Has|Remove}ByValue
        *** MISSING ***
    {Get|Set|Has|Remove}ByPropertyKey [ new in ES6 ]
        *** MISSING ***

The Objective-C API currently has:

    {Get|Set|Has|Remove}ById
        -valueForProperty: (et al)
    {Get|Set|Has|Remove}ByValue
        -objectForKeyedSubscript: (et al)
    {Get|Set|Has|Remove}ByPropertyKey [ new in ES6 ]
        *** MISSING ***

The ByPropertyKey variants are strictly more powerful than the ById variants. If we were designing this API from scratch we might not provide the ById variants.

Similarly, the ByValue variants are strictly more powerful than the ByPropertyKey variants. Since we *are* designing this part of the API from scratch, we can still decide not to provide the ByPropertyKey variants.

Now, some questions about your patch:

(1) Should we add ByValue to the C API? Why or why not?

(2) Should we expose an explicit ToPropertyKey operation? Why or why not?

(3) Should we provide ByPropertyKey in addition to ByValue? Why or why not?

My intuition is that we should just provide ByValue because it's the most powerful operation and ToPropertyKey is an internal implementation detail of it and other runtime APIs.

[Keith Miller]

I'm confused, there is no byPropertyKey operation, as far as I know. The toPropertyKey function is an implementation detail of how we convert a value into something we can use to lookup properties with. Reflect.get(value, property) is basically the same as value[property] it just doesn't toObject value, unless that's what you were going for. I'm assuming that's not what you mean though since the byId versions of the functions we provide assume a JSObjectRef. The methods I provided are the same a looking up by value. Perhaps we should use that suffix rather than the WithKey suffix.

I'm not sure if this is the right way to get around building internally on older OSs. We need this because if you are building JSC on Sierra/El Cap SDKs we will present the old signatures. 

The alternative to this is to keep the old implementations of these functions in JSValue.mm and not run the new tests on SDKs. I went with this version since it allows us to test our code even on non-High Sierra SDKs.

Let's try just suppressing the warning in the implementation file.

I also think it would be OK to #ifdef out id-specfic tests when building for older SDKs.

Next steps are fixing review comments, updating patch to trunk, API review, and notifying documentation about new API.

Its "inContext". (Capitalization is part of the method signature so it's API.)

Can we move these to an out-of-the-way place?

To match your other comment, I would say "These declarations provide compatibility when targeting SDKs for legacy OSs. In macOS 10.13 and iOS11 and below, 'property' was an NSString *.

> Source/JavaScriptCore/API/JSValue.h:334
> +@discussion Before macOS 10.13 and iOS 11 <code>property</code> was an NSString *, this was relaxed to id so JavaScript Symbol properties could be accessed.

I would say "Corresponds to the JavaScript operation object[property]. Pass an NSString * to access a named property. Other valid properties include symbols, numbers, and stringifiable objects. In macOS 10.13 and iOS11 and below, 'property' was an NSString *. " (Same in other places.)

Let's call this USE_NSSTRING_FOR_PROPERTY_KEY to avoid a name conflict from overly broad naming. We usually use "USE(X)" to mean that X is a project-wide feature. We do use NSString, so we need a more specific name.

I'm not actually sure where that should be. They need to be in the middle of the file somewhere since they are part of the interface and there is non-interface stuff at the bottom of the file. I put them below the newer API.

Objective-C allows you to add categories, which extend the interface, after the formal interface declaration. That's how our keyed subscripting declarations work, for example.

This doesn't seem like a useful intro.

Why do we assert not reached? This is a public API, developers may call this with a nullptr. I can see it being useful to know in a debug build as a warning, but it is certainly possible to have happen.

I think I convinced you earlier that we should go with a: JSC_AVAILABLE(JSC_MAC_TBA, JSC_IOS_TBA) and post-process like WebKit's processing:
Source/WebKit/postprocess-framework-headers.sh

We want to do it, because every time we add new API this happens, and now is as good a time as any!

Should we mark these as DEPRECATED? See WK_API_DEPRECATED_WITH_REPLACEMENT in WebKit2.

It might make sense to keep object as the last. Its a more natural fallback in case something did go wrong earlier.

Typo: "Obc-C"

Could you also add:

  checkResult(@"Should toString with description", [[symbol toString] isEqualToString:@"Symbol(dope)"]);

> Source/JavaScriptCore/API/tests/testapi.mm:617

Typo: "Seting" => "Setting" in a bunch of places.

It follows on the time honored tradition of software development, blaming people in the past!

I can remove it I suppose.

I think we want to know if a test accidentally passes a null context.

Yeah, I am still making the change I just haven't uploaded it yet.

Fixed.

>> +@interface JSValue (LegacyTargetSDK)
>

These won't even be visible unless you are targeting an older SDK. The post processor will run unifdef on all the public header files.

I was just doing it with the reinterpret_cast to match the C++ style. We don't use the C style casts where there is another option I don't see why we would want to do it here?

>> Source/JavaScriptCore/API/JSValueRef.cpp:92

Yeah, that's fair I supposed. I'll fix.

>> +

I like the new line since it breaks all the arguments to the function from the head of the loop more cleanly.

Don’t we want to eat this and inform callers that an exception occurred?

[Yusuke Suzuki]

Can we land this patch into the trunk?
Once it is introduced, I'll add a glib JSC API similar to this one :)

[Geoffrey Garen]

If there's interest now, let's land this patch as SPI, and we can take the steps to make it API separately.

What happens now if developers pass non-JS-ifyable values to this?

    [o valueForProperty:@"test"]; // good
    [o valueForProperty:myJSValue]; // good
    [o valueForProperty:[NSNull null]]; // good?
    [o valueForProperty:[[MyObject alloc] init]]; // bad

I'd expect at test, at least for the last, to ensure we get expected output (undefined) and not an exception or something.

Typo: "Obc-C" => "ObjC"

> Source/JavaScriptCore/API/tests/testapi.mm:691

I might be cool to have a test that sets `object[iteratorSymbol]` to be a ObjC block and verifies the block gets invoked and results are expected when iterating `object`. But that may be overkill.

Nit: The style elsewhere in this file is a space before the `()`

Is this debugging or expected output?

I added the test for the last one. This code  just calls the same method that the setValue called for the value.

So those should all work fine. If you pass a non-JSExported NSObject you will just get an empty wrapper object, which will get toPropertyKeyed when used as a property. i.e. it will return `o["[object Object]"]` in JS.

fixed.

I realized this function isn't needed.

Ditto.

Pro-tip: For integers you can just write `@1` instead of `@(1)`. For non-literals or floats you'd need to use the @(...) syntax.

Thanks for adding these additional tests, they look good!

It looks like this patch modified the Xcode build variables HEADER_SEARCH_PATHS inside of the Xcode project.

This seems unnecessary since this is already in the ToolExecutable xcconfig:

    ToolExecutable.xcconfig
    52:HEADER_SEARCH_PATHS = "$(JAVASCRIPTCORE_FRAMEWORKS_DIR)/JavaScriptCore.framework/PrivateHeaders" $(inherited);

Are these changes still necessary?

I dunno where those came from. I'll remove them all.

Whoops. I changed it to "Use zero since it will be less than any possible version number".
