[Mikhail Pozdnyakov]

EFL's LayoutTestController needs overridePreference method implementation, which is necessary for unskipping following test cases:

Implementation of LayoutTestController::overridePreference + common ewk_view settings interface

Provided common getter and setter interface for ewk_view settings.
Added 3 new ewk_view settings: EWK_VIEW_SETTING_ENABLE_WEBGL, EWK_VIEW_SETTING_HYPERLINK_AUDITING, EWK_VIEW_SETTING_TAB_TO_LINKS.
Added EWK_VIEW_SETTING_TAB_TO_LINKS ewk_view setting support to ChromeClientEfl::keyboardUIMode().
Added implementation of LayoutTestController::overridePreference()

Implementation of LayoutTestController::overridePreference + common ewk_view settings interface

The ewk_view_setting_{get,set}() stuff isn't very EFL-like, and is yet another place to maintain when adding/removing settings. I don't like this. 

One could easily write LayoutTestController::overridePreference() by calling directly the already existing ewk_view_setting family of functions, without sacrificing readability at the call site.

Informal r-.

Not all the necessary settings are currently present in ewk_view_setting family. 
Keeping the old approach would require adding of 6 new functions to the ewk_view interface (for 3 new settings). Solving of https://bugs.webkit.org/show_bug.cgi?id=83687 will also require adding of 2 more functions and so on.. 
Isn't it better to have a common setter/getter interface for all the settings?
The whole old ewk_view_setting family could be removed and it would significantly  decrease the size of ewk_view header file and improve its readability.

Mikhail's approach has been up for discussion before this patch was submitted, pls compare: https://lists.webkit.org/pipermail/webkit-efl/2012-April/000158.html 
Feedback there had been rather positive.

As you say, it is or becomes a "family" of functions, but a large one, given that there would be about 8 more functions to be added at least.

Could you reconsider your r-? It may not be 100% EFL style, but IMHO it's an improvement over adding more individual functions.

So, in a next step, the existing family of functions would be migrated to this approach.

Is it adding more functions for settings that bad?

If we use one function to set all the properties we are not going to reduce the amount of code, just the size of the header, but I don't think we really need that. The chromium port, as an example, has one function per setting too, similar to us.

I also don't think we should move webkit-efl exposed API away from the EFL coding style. This would just make things less consistent with the rest of the libraries.

Ok, we can move the discussion back to the ML if necessary. I'm going to answer to that thread too.

I'm not sure whether we need to add new API for hyperlinkAuditing setting. Are you sure ?

ditto.

We already have compile option for WebGL. When do we need to turn on/off webgl dynamically ?

Another solution could be off course to put these settings to DumpRenderTreeSupportEfl(just for enabling LayoutTestController overridePreference), however 
these settings are exported in other ports: GTK, Qt, mac, win, so 
I decided to keep efl port consistent with other ones.

Could be inline.

You can simplify this snippet by using the equals() overloads defined in JSStringUtils.cpp:
  return equals(value, "true") || equals(value, "1");

> Tools/DumpRenderTree/efl/LayoutTestControllerEfl.cpp:658
> +static int toInt(JSStringRef value)

Why not atoi(3)?

Fixed.

Doesn't it bring 1 more conversion for "val" to UString?
Fixed.

I had impression (probably wrong) that Eina_Value is an "official" mean for converting one type to another in EFL.
Fixed.

LGTM.  Looks like this breaks EFL build though.  rs=me, if you fix the EFL bot.

This patch is depended on Bug 84340. However, Bug 84340 needs to be splited into 3 bugs. When you land patches of Bug 84340, I will set cq+ for this patch.

[Dominik Röttsches (drott)]

We had an issue in bug 82860, fixed in 84430, with missing resets in DRT. Can you check that your new settings are reset before each test?

Mikhail, I'm adding support for the "WebKitLoadSiteIconsKey" setting overriding at Bug 85171. Our patches are complementary so I thought you should be aware.
