- The tab switcher is responsible for asynchronously switching
- tabs in e10s. It waits until the new tab is ready (i.e., the
- layer tree is available) before switching to it. Then it
- unloads the layer tree for the old tab.
-
- The tab switcher is a state machine. For each tab, it
- maintains state about whether the layer tree for the tab is
- available, being loaded, being unloaded, or unavailable. It
- also keeps track of the tab currently being displayed, the tab
- it's trying to load, and the tab the user has asked to switch
- to. The switcher object is created upon tab switch. It is
- released when there are no pending tabs to load or unload.
-
- The following general principles have guided the design:
-
- 1. We only request one layer tree at a time. If the user
- switches to a different tab while waiting, we don't request
- the new layer tree until the old tab has loaded or timed out.
-
- 2. If loading the layers for a tab times out, we show the
- spinner and possibly request the layer tree for another tab if
- the user has requested one.
-
- 3. We discard layer trees on a delay. This way, if the user is
- switching among the same tabs frequently, we don't continually
- load the same tabs.
-
- It's important that we always show either the spinner or a tab
- whose layers are available. Otherwise the compositor will draw
- an entirely black frame, which is very jarring. To ensure this
- never happens when switching away from a tab, we assume the
- old tab might still be drawn until a MozAfterPaint event
- occurs. Because layout and compositing happen asynchronously,
- we don't have any other way of knowing when the switch
- actually takes place. Therefore, we don't unload the old tab
- until the next MozAfterPaint event.
