Details

(Whiteboard: [rm-docshell-tree-item:simple])

In file dom/base/nsCCUncollectableMarker.cpp

Retrieves DocShell from tree-item, performs marking code.

Iterates over children to recurse.

Cycle-collector by definition only cares about in-process memory.

Change to using BrowsingContext to iterate over in-process child docs.

  • Skip over out-of-process children.

Kannan says replacing nsIDocShellTreeItem calls should block enabling Fission in Nightly (M6).
