[EFL] New signals in ewk_view to enable global history delegate functionality

• Component: WebKit EFL
• Status: RESOLVED FIXED

[Mikhail Pozdnyakov]

New signals are needed to be attached into ewk_view to enable global history delegate functionality for EFL port( and unskip http/tests/globalhistory testcases). 
Global history delegate is an interface for WebKit clients to manage their own global history store.

The new signals should do following:
1) report that view did navigation and give the navigation details.
2) report that view performed a client redirect and give source and destination uris.
3) report that view performed a server redirect and give source and destination uris.
4) report that client should fill the visited links set.

Move '*' pointer to variable side.

ditto.

We are using efl coding style for public header files. So, clientRedirectSource need to be changed. For example, has_substitute_data.

> Source/WebKit/efl/ewk/ewk_view.h:311
> +    const char* clientRedirectSource;  /**< client redirect source url*/

ditto.

I don't understand why we need to send this signal. Could you explain this ?

From ./Source/WebCore/ChangeLog-2008-08-10: 
Added populateVisitedLinks function, used to fill the
visited links set from the global history at application startup time.

So this signal is send to the client when when webcore needs information about visited links from a persistent history storage (managed by the client).

If so, I wonder how to set visited link information from client. Does ewk already have _set() APIs?

As far as I know such api is not available on EFL port and this signal can be used in DRT tests only at the moment.

I could add this api, but I would create a separate bug for it.

From functionality point of view, I think we have to add a pair of function. In this case, it seems you need to implement functions that client sets according to "populate,visited,links" signal. Or, I think you're able to file a bug for "populate,visited,links"  signal.

I've removed "populate,visited,links" signal from the patch, the bug86370 will be responsible for both the signal and new API setting visited link information from the client.

Looks make sense except for my trivial comment.

I heard that webkit changelog sublates to use '-', '1), 2)' and so on. I'm not sure whether we can use 1) in ChangeLog.

I would define a Ewk struct for this. This is less bug-prone for the client.

Ditto.

Remove space before the *. Also minor typo: "URIs"

> Source/WebKit/efl/ewk/ewk_view.h:76
> + *  - "perform,server,redirect", const char **: reports that view performed a server redirect and gives source and destination URI's.

Ditto.

Couldn't we make this a pointer to avoid copying the struct?

> Source/WebKit/efl/ewk/ewk_view.h:312
> +    Ewk_Frame_Resource_Response response;  /**< Navigation response. */

Ditto.

According to WebKit coding style, we should avoid abbreviations. -> destinationURL.

According to WebKit coding style, boolean variable names should start with words like "is", "did", "should", "has"...
