US Patent 9021592 Source code analysis of inter-related code bases

A method and system for analyzing source code is disclosed. A computer identifies a call in a first source code to an application programming interface in a second source code. Responsive to identifying the call in the first source code to the application programming interface in the second source code, the computer determines whether a set of policies for calls to application programming interfaces includes a policy for calls to the application programming interface. Responsive to a determination that the set of policies for calls to application programming interfaces does not include the policy for calls to the application programming interface, the computer generates the policy for calls to the application programming interface and adds the generated policy to the set of policies for calls to application programming interfaces.
