Bug 164199 – [WTF] Import std::optional reference implementation as WTF::Optional

• Component: Web Template Framework
• Status: RESOLVED FIXED

[Yusuke Suzuki]

WTF::Optional<> uses placement new. It makes this thing non-literal-type, and prevent us from using Optional in constexpr.
This means that we cannot use `static const XXX value` global variable where XXX includes Optional<> thingy since we WebKit do not allow global constructors.

[Yusuke Suzuki]

Actually, DOMJIT::Effect includes Optional<> thing.
If this Optional<> becomes literal type, we can use DOMJIT::Effect in static const variables.
And it allows us to generate DOMJIT signatures from IDL easily.

[Yusuke Suzuki]

Note that C++17 std::optional requires that std::optional<literal type> is literal type.

[Yusuke Suzuki]

I have a patch for that, changing the current WTF::Optional to support these features.
But given the large change, I wonder if we just include LLVM libc++'s std::experimental::optional. It has complete interface aligned to the C++17 draft.
I remember that we import the implementation for std::variant from somewhere.

I mean that importing the libc++ optional header, rewriting some part of it to adopt it in WTF, and renaming it as WTF::Optional. This is the same way to the WTF::Variant.

[Yusuke Suzuki]

Note that the implementation technique is described in the original std::optional proposal paper.
In the case of std::is_trivially_destructible<T>::value = true, we use the union of dummy type and T for the storage.

struct Dummy { };
union {
    Dummy dummy;
    T value;
};

You mean importing this:
https://github.com/llvm-mirror/libcxx/blob/master/include/experimental/optional
?

Assuming importing MIT-licensed code is OK, that sounds like a fine approach since it'll be in C++17. Makes it easy to transition in the future.

Right, with some modification to adopt it in WTF.
I remember we already import some of the University of Illinois Open Source Licenses things.

[Yusuke Suzuki]

Interesting. This change figures out that there are some classes deleting move assignment operator but having move constructors. And they use WTF::Optional. It seems that this becomes compile error with C++17 std::optional.

I'm not sure I understand why the code would do this. Is it just misguided?

Which classes?

Oops, no. I misunderstood. Some classes define move constructor, but they do not define move assignment operator. And these classes are noncopyable. They deletes copy assignment operator.
At that time,

Optional<XXX> value;

value = XXX(...);

causes compile error.
The example is DFG::FPRTemporary, DFG::JSValueOperand, DFG::SpeculateCellOperand.
And it seems that DOMPromise is also the thing.

Ah, it is incorrect for DOMPromise. In DOMPromise, it has move constructor. But it does not have move assignment operator.

[Yusuke Suzuki]

OK, I've found the thing.

DOMPromise also has the same issue.
DOMPromise has move constructor. But it does not have move assignment operator.
It seems that it has copy assignment operator (operator=(DOMPromise const&) = default). But actually it does not.
It is ill-formed since the member Ref does not have copy assignment operator.

Previously WTF::Optional<>::operator=(WTF::Optional<T>&&) does not use move assignment operator. It always destroy the current content if |this| is engaged. So, the only move constructor is used.
But new optional uses move assignment operator in that case.

I wanted to overload Optional<bool> to use a 3-state enum instead of two bools to make it so there is only one read operation when using it.  Will optimizations like that be possible once we switch to this or c++17?  I haven't actually read the generated optimized assembly or measured anything yet

What you're proposing may be faster (check the assembly, but I assume so). libc++ is unlikely to change its implementation in this manner past C++17 because it would affect ABI. We don't have to care about ABI IIUC, so we can change it as we want.

On the other hand, we'd likely want to remove our version once we move to C++17. If the version you have in mind is faster I can help review and commit the change in libc++ (I still have commit access).

Can we specialize the C++17 std::optional?
I mean, is it allowed in the spec?
I remember that these attempts are typically undefined, maybe, small part of C++ things are allowed. (like, std::hash, std::swap). Is it correct?

And another potentially useful specialization is, Optional<T&>. Having T* internally and use nullptr for Nullopt case.

You can but AFAIK it's UB. It means that we'd *need* to #include <wtf/optional.h> and *never* #include <optional>, lest we mess up our internal ABI. Seem fraught with peril when we could fix the implementation before C++17 is finalized.

Yeah that could work as well.

OK, ready for review.

Oops. I'll use lowercase `optional` here later.

This patch seems reasonable to me, however, this implementation feels 10x harder to understand than our implementation (hopefully it's doing important things with that complexity) . It'll be nice when we can remove the implementation entirely.

I think it's good to get other folks' opinion on this change, too. Maybe Anders/Darin/Sam have opinions?

If this is the same as (the coming) std::optional, maybe we should keep that name. I'm assuming once we can use std::optional we can just drop this one.

OK, let's make this WTF::Optional to std::optional for a while.
When C++17 comes to WebKit, we can just drop this header!

[Sam Weinig]

rs=me with that change.
