This shouldn't be needed.

This shouldn't be needed.

On Mac we use .../WebKit/Databases/___IndexedDB.  We should probably do something similar here.

This should probably be false by default, then set to true for DumpRenderTree and MiniBrowser.

Thanks for reviewing :)

I get a compile error without this:

error C2248: 'WebCore::IDBServer::MemoryBackingStoreTransaction::MemoryBackingStoreTransaction': cannot access private member declared in class 'WebCore::IDBServer::MemoryBackingStoreTransaction

Maybe we should fix this in another way?

I get an error without this:

error C2668: 'WebCore::IDBServer::UniqueIDBDatabase::storeCallback': ambiguous call to overloaded function

I will update the path :)

I am afraid I didn't find a better way to fix these compile errors.
The main problem seems to be that MSVC does not accept that std::make_unique is declared as a friend of a class.

Just make the constructor public.

Looks good.  I think this needs another iteration, though.

Style bot wants a space here.

Is this really necessary?  What error does this prevent?  Can we not forward declare things?  Including more headers in a header like this makes the build slower.

> Source/WebCore/bindings/js/JSDOMWrapper.h:25
> +#include "DOMWrapperWorld.h"

Ditto.

> Source/WebKit/win/storage/WebDatabaseProvider.cpp:41
> +        return String("");

This isn't used in WebKit.  I think this is what emptyString() is for.

> Source/WebKit/win/storage/WebDatabaseProvider.cpp:50
> +        return String("");

ditto.

I get the error:

wtf/PassRefPtr.h(42): error C2027: use of undefined type 'WebCore::DOMWindow'

PassRefPtr<DOMWindow> is used in JSDOMWindowBase.h, but this fails to compile since the class DOMWindow is only forward declared here.
