Bug 92345 – [EFL][WK2] Add back forward list API

• Status: RESOLVED
• Resolution: FIXED
• Component: WebKit EFL

[Mikhail Pozdnyakov]

Back forward list API is missing in EFL WK2 and should be added.

patch

Does not contain yet wrappers around 
WK_EXPORT WKArrayRef WKBackForwardListCopyBackListWithLimit(WKBackForwardListRef list, unsigned limit);
WK_EXPORT WKArrayRef WKBackForwardListCopyForwardListWithLimit(WKBackForwardListRef list, unsigned limit);

would upload a separate patch for it.

Needs to be removed.

These 2 headers need to be added to EWebKit2.h as well.

Minor, but I prefer *Map than *Cache.

> Source/WebKit2/UIProcess/API/efl/ewk_back_forward_list.cpp:50
> +    { }

Missing destructor. You need to unref all the values in the map.

EINA SAFETY for wkItem?

> Source/WebKit2/UIProcess/API/efl/ewk_back_forward_list.cpp:72
> +        ewk_back_forward_list_item_ref(item); // increase ref count for stored items.

ref count is already 1 after the new, which is enough for storing. If the client wants to keep a reference, it should ref it by itself.

> Source/WebKit2/UIProcess/API/efl/ewk_back_forward_list.cpp:82
> +    return getOrCreateItem(list, WKBackForwardListGetCurrentItem(wkList));

We try to use blank line before return statements (same below).

> Source/WebKit2/UIProcess/API/efl/ewk_back_forward_list.cpp:91
> +Ewk_Back_Forward_List_Item* webkit_back_forward_list_forward_item_get(Ewk_Back_Forward_List* list)

How about ewk_back_forward_list_next_item_get() and ewk_back_forward_list_previous_item_get() ? While correct, the current naming looks weird ewk_back_forward_list_forward_item_get.

> Source/WebKit2/UIProcess/API/efl/ewk_back_forward_list.cpp:94
> +    return getOrCreateItem(list, WKBackForwardListGetForwardItem(wkList));

What if WKBackForwardListGetForwardItem(wkList) returns 0? This needs to be handled.

> Source/WebKit2/UIProcess/API/efl/ewk_back_forward_list.cpp:100
> +    return getOrCreateItem(list, WKBackForwardListGetItemAtIndex(wkList, index));

Need to handle when WKBackForwardListGetItemAtIndex returns NULL.

> Source/WebKit2/UIProcess/API/efl/ewk_back_forward_list.cpp:144
> +    delete list;

I would add an EINA SAFETY on list even if it won't crash.

> Source/WebKit2/UIProcess/API/efl/ewk_back_forward_list.h:50
> +EAPI Ewk_Back_Forward_List_Item *webkit_back_forward_list_current_item_get(Ewk_Back_Forward_List *list);

wrong naming: ewk_*
list argument should be const since it is a getter.

> Source/WebKit2/UIProcess/API/efl/ewk_back_forward_list.h:59
> +EAPI Ewk_Back_Forward_List_Item *webkit_back_forward_list_back_item_get(Ewk_Back_Forward_List *list);

Ditto.

> +EAPI Ewk_Back_Forward_List_Item *webkit_back_forward_list_item_at_index_get(Ewk_Back_Forward_List *list, int index);

Ditto.

> Source/WebKit2/UIProcess/API/efl/ewk_back_forward_list.h:87
> +EAPI unsigned webkit_back_forward_list_length_get(Ewk_Back_Forward_List *list);

wrong naming: ewk_*
Based on Eina_List API, I would call this ewk_back_forward_list_count().
Argument should be const.

> Source/WebKit2/UIProcess/API/efl/ewk_back_forward_list_item.cpp:39
> +inline const char* getItemProperty(WKBackForwardListItemRef ref, const WKRefType& val)

Ref types are not usually passed by const reference in WebKit2 I believe.

> Source/WebKit2/UIProcess/API/efl/ewk_back_forward_list_item.cpp:84
> +    if (!--item->__ref)

We usually prefer the opposite in WebKit (return early).

if (--item->__ref)
  return;

delete item;

> Source/WebKit2/UIProcess/API/efl/ewk_back_forward_list_item.cpp:91
> +    return item->uri;

Blank line before return statements are preferred.

> Source/WebKit2/UIProcess/API/efl/ewk_back_forward_list_item.cpp:109
> +    return ewk_back_forward_list_item_new(backForwardListItemData);

Infinite loop?

> + * Retuns URI of the item.

"Returns"

Why? Maybe we can improve the doc here by explaining.

> Source/WebKit2/UIProcess/API/efl/ewk_back_forward_list_item.h:63
> + * @sa ewk_back_forward_list_item_original_uri_get().

I think we use @see in the other files.

> + * @return the URI of the @a item or @c NULL in case of error.

It should be indicated that the returned value is guaranteed to be stringshared. See other files for examples.

This is done to 1) say explicitly that the function has return value which is not going to be used; 2) avoid possible compiler warnings

this comment is not quite clear for me. Could you please clarify how it should look? I can see the similar formatted return value descriptiop in many other ewk_ headers.

why the () around list?

I find the naming confusing. Or the way of doing this. It has like the wrong level of abstraction. I understand that you are wrapping the items and then caching them as this in itself is a kind of wasteful operation.

I guess I would just call this addItemToWrapperCache() or so. That makes it pretty obvious what it is doing. Add methods normally return the item inserted.

> Source/WebKit2/UIProcess/API/efl/ewk_back_forward_list.cpp:132

I dont think the void cast is needed

Wouldn't it be smarter to make a EinaStringShare<const char*> "smart pointer" like class:

class EinaStringShare< .... {
   EinaStringShare(T string) { value = eina_stringshare_add(string) };
   ~EinaStringShare() { eina_stringshare_del(value) };
   T data() { return value; }
private:
   T value;
}

You could make something like this work with char*, const char*, WKString etc

Theoretically 'list' here can be some expression, so missing () could lead to erroneous usage of operator '!'.
As far as I remember macro args are always treated like this..

Yeah, that's great idea :) such class could be re-used in many places..

It is probably nicer making this take a WKURLRef or a WKStringRef directly. You can retain the ref inside the constructor.

Yes, please do so in a separate patch (and mind that depending where you put it you should follow WebKit's or EFL's naming style -- for example, if this was really declared here it should be called Eina_String_Share).

I wouldn't necessarily make this bug depend on the other implementing this class, though, as all places can be changed at once later.

It is not really an EFL API offering, just like the WKRetainPtr's are not Apple WK2 C api offerings, but they are there to be more useful when coding C++ in WebKit. Thus it makes sense to make this follow WebKit style

This issue will be addressed at bug93229, however can I yet proceed with a local helper class here for back-forward list implementation and substitute it later with a generic wrapper class that appears in bug93229 ?

This class does not know whether the WKSmthRef it is given was copied before (and hence shall be adopted) or not, so I would keep it like this..

Maybe IMPL instead of WK ? or 

#define EWK_BACK_FORWARD_LIST_IMPL_GET_OR_RETURN(list, impl, ...)

That is at least easy to understand

You could give it the AdoptWK argument :-)

IMO, this file is to expand ewk_view.cpp features. So, it seems ewk_view.h can be moved to below config.h.
