I am trying to do some deep code analysis on a python2 codebase that is large and messy enough that most analysis tools I've tried have not worked. I have however been able to use pycscope to generate a cscope database. I can even use it to do basic things like find function usages or all functions called directly from a given function.
To me, it seems like the fact that there is a database and that it can be used for simple things means that it should be possible to use it for more complex things too. For example if I wanted to find all functions that are called from within a given function recursively, or all codepaths that depend on that function.
However cscope documentation is very light and I'm not much of a c-expert. Is there an actual query language for it? An extension that knows how to use the database in this manner?
