471563 - disconnected uri nodes should be marked as such

Status: NEW

(Toolkit :: Places, defect, P3)

Description

[Dietrich Ayala (:dietrich)]

scenario:

1. query for bookmarks
2. get a reference to a bookmark uri node
3. do something that causes the query result to refresh (ie: it deletes all children and refills)

you're left with a bookmark uri node that will not live-update because it's been disconnected from it's parent.

first, should this be able to happen at all? should the nodes remain in memory as long as there's a reference to them?

otherwise, in the absence of a parent, uri nodes should update themselves.

* They shouldn't update themselves for sure since they're not part of the result anymore.  However,  we should mark them as useless somehow.  One option is to return NS_ERROR_NOT_AVAILABLE for all property (except parent,  maybe).

* The selection-persistence code in  placetreeview check the parent property in order to identify obsolete nodes.
