Bug 154559 – Some timer alignment cleanup.

• Component: WebKit Misc.
• Status: RESOLVED FIXED

[Gavin Barraclough]

Document shouldn't override Page's timer alignment policy with a lower alignment, and m_domTimerAlignmentInterval isn't really a Settings, it's just the current state for the page.

You should change this to use std::chrono::milliseconds!

> Source/WebCore/page/Page.h:620
> -    bool m_timerThrottlingEnabled;
> +    bool m_timerThrottlingEnabledTime;
> +    double m_timerAlignmentInterval;

Can this use Optional instead?

Heh, probably! - sure I'll look into this. (But as a separate change - these intervals are all currently doubles & I should probably switch double -> chrono::milliseconds in a bunch of other places at the same time).

Interesting. I don't think this should be an Optional - when timer throttling is disabled the timer alignment property does still hold a value (DOMTimer::defaultAlignmentInterval() - which theoretically could be non-zero).

Also I plan on replacing m_timerThrottlingEnabled with the timestamp at which time throttling is enabled, so we know how long it has been - come to think of it, that probably should be an Optional.

I prefer the previous name since this is a boolean.

Oops, yes!
