[EFL][WK2] ewk_back_forward_list_item properties should be in sync with WebProcessProxy::m_backForwardListItemMap

• Component: WebKit EFL
• Status: RESOLVED FIXED

[Mikhail Pozdnyakov]

Currently ewk_back_forward_list_item properties are initialized from WKBackForwardListItemRef once in the constructor and then just stored.
This is erroneous approach as back forward items can be initialized within several iterations, meaning several ipc calls to UI process and several updates of WebProcessProxy::m_backForwardListItemMap where the items are stored. Hence the values of ewk_back_forward_list_item properties should be updated with the corresponding WKBackForwardListItem.. functions invokes every time they are called.

Personally, I would prefer this on 2 lines.

Ditto. + You should use wkItem directly instead of item->wkItem.get().

> +    return item->originalUri = WKEinaSharedString(AdoptWK, WKBackForwardListItemCopyOriginalURL(item->wkItem.get()));

Ditto.

Use '.' instead '..' at the end of WKBackForwardListItem.

hmm you need to assign to this from const methods? maybe mention in the changelog

It is a RetainPtr class... what is the diff between checking if wkItem is Null and wkItem.get() ?

Agree, it has bool operator overloaded. Thanks for the catch.

Controversial but I think it is a legit case of using mutable. Looks to me it is because the getter is lazy initialized, right?

Why are you using __VA_ARGS__ here?
