Multi file Callgraph analysis

[OmkarPh]

For every class/function definition we're maintaining a fully qualified namespace including filename, eg.

codebase/path/to/file.py//ClassName//MemberFunctionName

This should facilitate combining the graphs of multiple files declaratively.

Some challenges we need to solve in order to achieve this -

• Resolve file path from module name Javascript imports Python imports

• Correctly associating assignment graphs
  While building callgraph for file abc.py, we may not already have information about one of its imported files - pqr.py . Hence, entire relationship needs to be built after all files are parsed. It is a bit tricky to associate the relationships as a post-processing step with minimal information

• Decide when to accumulate results
  We can either combine results of all files or accumulate all graphs as we process (this can pose concurrency issues)
