Bug 154926 – Add Page::TimerThrottlingState

• Status: RESOLVED
• Resolution: FIXED
• Component: WebKit Misc.

[Gavin Barraclough]

Hidden page timer throttling is currently a boolean state, indicated by whether the Optional m_timerThrottlingEnabledTime is in a set/unset state. When enabled, the increasing mechanism may or may not be enable, this is controlled directly by the setting.

Refactor to add a enum tracking timer throttling being in one of three states - disabled, enabled, or enabled-throttling. This cleans things up, and will enabled up to introduce a dynamic policy for when enabled-throttling is enabled. (Behavior is unchanged in this patch.)

Typo: "a enum"

"enabled-increasing" ?

We could also assert that m_timerThrottlingEnabledTime is not 0.
