Use a ServiceWorker process per registrable domain

• Component: WebKit2
• Status: RESOLVED FIXED

[Chris Dumez]

Use a ServiceWorker process per registrable domain instead of one per security origin. This is more in line with PSON and avoids launching too many processes.

Maybe uniform initialization here?

Not an issue for this patch, but I wonder how this singleton interacts with multiple NetworkProcess instances.
Ideally, we would not rely on this singleton and instead rely on NetworkProcess::m_serverToContextConnections.

Can we remove this include?

> +    , m_registrableDomain(scriptURL)

Can we use m_data.scriptURL here instead of scriptURL?
We might want to make scriptURL a URL&& and move it as part of m_data construction.

I think you are right but this should probably be dealt with separately.

I filed https://bugs.webkit.org/show_bug.cgi?id=195697 for the singleton issue to not forget about it.
