Details

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

In file dom/base/nsScreen.cpp

Uses DocShellTree to get same-type root of DocShell associated with incoming window.

  • Calls “SetOrientationLock” on the root docshell.

Called from Screen::mozLockOrientation web API

Root can be out-of-process.

Low-frequency event that is coarse grained and not that performance sensitive.

Convert to BrowsingContext to traverse ancestors.

  • If tree goes out of process, use IPC to forward SetOrientationLock to correct process.

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