I think this can be an assertion.

Maybe call this containsPluginViewsWithPluginProcessToken to match the other two member functions.

Done (removed the call to invalidate and the early return and replaced it with an assertion).

Done.

For those watching at home. Anders r+’d the second version of the patch with these same considerations.

I know Anders already reviewed it, but I did too. r=me

I think these names are too wordy. How about PlugInInformation instead of InformationForPlugIn and omitting WithProcessID. Do we need other GetPlugInInformation functions that don’t take a process ID?

The naming here seems sort of “Cocoa method style”. I would probably have called these findPlugInProcessByID and findPlugInProcessByToken.

Should be callback.release() rather than callback.get().

Why protected instead of private?

I modeled this a bit off of WKContextGetInfoForInstalledPlugIns in WKContextPrivateMac.h, which does not take a process ID.

However, I am fine with PlugInInformation given that the type of the argument is clearly pid_t.

Will do.

Will fix.

I will make it private.

I already committed the patch. rs=you on these changes?

Thanks!
