Transcript

1. Spree upgrade catch up
2. So far
3. Spree fork
4. Fixes from newer Sprees and OFN folks
5. Approach
6. gem 'spree', github: 'openfoodfoundation/spree', branch: 'step-6a', ref: '86bf...'
7. Moving ahead of master in batches of 100 commits
8. ⾠ Upgrading to unknown states
9. At the very best, the tests were passing...
10. Proposal
11. 2-0-stable branch
13. ! the fork
14. Let's go for gem 'spree', ~> 2.0 !
15. that is 1656 commits and > 40 migrations ahead of us
16. Smallest upgrade as possible
17. truth: the app fails fails until 2.0.8...
18. ! we can backport the patch
19. Maintain the fork
20. own it and consider it part of the product
21. Just to give Spree the extensibility it didn't have in 2.0
22. Use best practices: CI, PRs, Code review
23. Stay away from it otherwise* *we might need to bring in critical fixes, though
24. Enrico: Why not putting the hooks/abstraction in a separate gem?
25. Spree needs to be aware of them
26. Simpler to learn Spree than hacking it
27. APIs and tests vs Metaprogramming
28. Trade complexity for indirection
29. Check coopdevs/spree #6 and off/ofn #2256
30. Discuss
