[EFL][WK2] {Vibration,Battery,NetworkInfo}Provider should contain WKContextRef instead of proxy.

[Byungwoo Lee]

There is an unclear relation between WebContext and {VibrationProvider, BatteryProvider, NetworkInfoProvider}

VibrationProvider has WKRetainPtr<WKVibrationRef> m_wkVibrationRef which has reference for object WebVibrationProxy.

But the WebVibrationProxy instance is a member of WebContext which also has RefPtr<WebVibrationProxy>

Two classes are sharing the reference for WebVibrationProxy but there is no relation between the two.

This can make a problem that,
When WebContext if deleted befor the VibrationProvider, WebVibrationProxy will be alive without WebContext,
because VibrationProvider also has the reference for WebVibrationProxy.

This is a problem because WebVibrationProxy should be a member of WebContext.

To prevent this,
there should be a relation between VibrationProvider and WebContext.

(And same about BatteryProvider, NetworkInfoProvider)

It looks like we are missing the networkInfoProvider, right? We should probably fix this in a separate patch.

Addressing the missing networkInfoProvider initialization issue in Bug 97865. This patch will need rebasing afterwards.

Yes. How about this?
[EFL][WK2] {Vibration,Battery,NetworkInfo}Provider should contain WKContextRef instead of proxy.

Yes I couldn't find a code about networkInfoProvider. it should be fixed in other patch :)

Yes, I think it is better.
