Bug 182363 – WebAppManifest scope should default to the containing directory of start_url if 'scope' is not specified

• Component: WebCore Misc.
• Status: RESOLVED FIXED

[David Quesada]

See https://github.com/w3c/manifest/issues/550#issuecomment-361129547

The spec is likely going to be updated to match Chrome's behavior, which some web apps rely on.

Just do: URL(url, "./"). What's what service worker code does.
Also, we should this help function scopeURL or computeScopeURL or something.
"containing URL" is not really a nominal terminology.

That's a lot cleaner. I'll use that instead.

Hm... I would have preferred to have a helper function like you did earlier.

I'm open to adding back a helper function. How does `void defaultScopeURL(const URL& startURL)` sound?

Sure that sounds good. Alternatively, you could just compute it once at the top of the function
as defaultScopeURL local variable since this isn't a perf sensitive code.
