Futzing with data from git using pygit2

gitfutz

This repos is for me to test ideas out for analyzing git repositories. I am using the python libgit2 bindings as provided by pygit2.

Initial Questions

I want to see if I can answer the following questions:

• What is the developer heirarchy?

  The merge information may provide insight into the social structure of the project. I want to see if it does for some (manually) selected github projects.

• Volatile vs Non-Volatile lines.

  I want to be able to identitfy for a range of commits (or times) what lines are considered "volatile" lines and what lines are considered "stable."

• Volatile vs Non-Volatile code structures.

  Same things as lines except look at specific code structures. I will probably use an AST representation of the code for this but a flow graph might also work.

There are lots of other questions to ask but these seem to be good ones to start with. The volatile vs non-volatile [lines|stuctures] in particular leads questions about those types of [lines|structures]. For instance one would like to know if a non-volatile block is dead or not. This would require dead code analysis. Another simple question, given a non-volatile block do any tests in the test suite cover it? Do block stabilize (become non-volatile) before or after a test suite covers the block?
