<pre style="margin: 0; padding: 0; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">QML has very strange visibility rules. Here is an example:
import QtQuick.Controls 1.1
Label {
id: label
text: "Hello"
Button {
id: button
onClick: { label.hello = "World"; }
}
}
"button" is an object that is declared inside label, and thus has an inner context that is a child of the context of "label". However, "button" cannot see the "text" property of "label", even if this property is declared in a parent context. "button" can see "label", though, as "label" is declared in the top-level context (using Declaration::setContext, this was already the case without this patch).
The inner context of a QML object therefore must be able to see the top-level context, its imported parent contexts (class inheritance), but not its parent context. This patch handles that by introducing QmlDUContext, a subclass of DUContext. QmlDUContext provides a method that allows DeclarationBuilder to specify that a context should be blind to its parent (but not the top-level context, hence the addImportedParentContext(topContext()) call).</pre>

<pre style="margin: 0; padding: 0; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">Two new unit tests have been added. The first one ensures that the code-completion doesn't list symbols that should not be visible, and the second one checks that UseBuilder does not see uses where there shouldn't be any.
All the other unit tests still pass, but I'm not very confident of the implementation of QmlDUContext. There were many things to take into consideration, many constructors to implement, a macro that mustn't be forgotten, special setClassId calls, etc. I hope that I haven't missed anything, but I'm not sure (valgrind doesn't complain about anything, though, but I'm afraid of subtle cache-related bugs). No other language support plugin that I know (kdev-clang, kdev-oldcpp, kdev-python, kdev-ruby) subclasses DUContextData (they subclass DUContext, though), so I had no example.
