Bug 89087 – Web Inspector: Remove devtoolsInjectedScript hidden property

• Component: Web Inspector (Deprecated)
• Status: RESOLVED FIXED

[Andrey Adaikin]

We use this hidden property to reference a InjectedScript object for a given ScriptState, but we also have the same reference in the InjectedScriptManager's hash maps. Just use the hash maps and remove the hidden property from the global object.

General approach looks good, but I'm a bit concerned with consistency between two maps (m_idToInjectedScript and  m_scriptStateToId) being not obvious.
Also a nit -- Google copyright line should only include last year.

When are we supposed to hit this check?

Ok, looks like it's normal for us to hit this. LGTM then.

InjectedScriptManager should not be aware of "WebGL".

Then it also should not be aware of the InjectedScript class.

Now that this is removed how can we make sure that the injected script is not garbage collected?

Nevermind. I missed that it is kept as a strong ref in ScriptObject.
