Roadmap

If you've poked around my Github repo, you'll also notice I have a Go version of this called Helmet. It's still far behind in functionality and full of bugs but is dramatically faster. I haven't decided which one I will put most of my (very limited) time into.

Needs

• Speed, speed, speed. Trilby is more or less on par with MAT but has the potential to be faster, and also doesn't cache scan results to disk like MAT does. Notably I'd like
  • Multi-threaded heap scan
  • Multi-threaded query processing
  • Dominator analysis in O(n) time and space (currently uses Lengauer-Tarjan, with a minor change to pre-filter leaf trees)
  • Code hotpoints rewritten in Java
• Reduced memory usage. There are several opportunities for optimizing sizes, graph offsets, and other places where we store per-object or per-reference information.
• A UI. The command line was great for getting the tool off the ground, but that won't take it very far.
• A query tutorial.
• Better error messages out of the query PEG (maybe rewrite using Parboiled?)
• Better use of Scala features (without killing the GC) and better Scala coding style in general. :-)
