4. FETCHING Metadata
5. Tale of Two Indices
6. Bundler 1.1 Dependency ! API
7. The Great RubyGems ! DDOS
8. New! Bundler API ! Host
9. Shortcomings •Less Secure •Impossible to cache •Not Server Friendly •No checksum, Ruby and RubyGems platform support
10. Work on New Index Format
11. The New Index •More Secure •Easier to Cache •Less Server side work •Checksum, Ruby and RubyGems platform support
12. What about now? •Use Bundler 1.6 RC2 •Use source mirrors •Use bundle pack
13. RESOLVING Dependencies
14. The hardworking resolver
15. Resolving dependency is an NP complete problem
16. The existing dependency algorithm is recursive
18. The new dependency resolver
19. The new resolver •Iterative •Utilises CSP algorithms •Prunes the search space much better •Resolves dependencies better
20. What ! about the! performance?!
21. What about now? •Use Bundler 1.6 RC2, again! •Use version constraints •Use parallel gem installation
22. Exciting ! things ! coming up ! in Bundler!
23. Thanks
