When using the C++ API to change scalars from child processes, we don't check if we're expected to record from the process [1].

This is happening for all the scalars operations, but it's not happening for the parent process, which looks ok as internal_GetRecordableScalar checks for that too [2].

Chris, any chance you could review this? No rush though :)

The background here is that the C++ API paths were not checking if we were allowed to record scalar data in the current process. The JS API was. Part of the problem was that the function checking for the "permissions" were different: I've refactored the code a bit to use the same code in both places.

I've also filed bug 1333026 to extend the C++ API test coverage to content scalars as well.
