This PR adds the functionality of tracking the creation of objects using a class constructor.
The intended code to be tracked is shown below:
In this case, the
__init__
method returns None; therefore, when the method is instrumented with theProvenance
decorator, the actual constructed object is not identified.With the changes in this PR, the object stored in
obj
will be tracked as the output of the functionConstructor.__init__
, to disambiguate from other class methods where the object is the input. For that, theConstructor.__init__
method needs to be instrumented with the decorator, as any other object method.Unit tests are implemented to check the correct behavior and integration with other provenance tracking functionality already implemented.
