Bug 104220 – [V8] Implement v8IntegerWithoutIsolate(int i)

• Component: WebCore JavaScript
• Status: RESOLVED FIXED

[Kentaro Hara]

To make an Isolate mandatory in v8Integer(), we implement v8IntegerWithoutIsolate(int i) for call sites that don't have an Isolate. Eventually we want to kill v8IntegerWithoutIsolate(int i).

You might also consider the name deprecatedV8Integer to inform people writing future patches that they shouldn't add more callers of this function.

We should be able to store the isolate in a member variable of Dictionary.  Code isn't allowed to hold on to Dictionaries past the call frame in which they receive them.

Good idea. Will fix before landing.

Oops, Dictionary already holds m_isolate. I can use it here. Will fix it.
