Working towards Bundler 3

Bundler hit a big milestone this year with the release of Bundler 2 🎉, but not without its bumps and hurdles. We'll look into the problems that some of our users have been experiencing after the Bundler 2 release, what the core team has been doing to fix these issues and what we've since learned. Afterwards, We'll look at the upcoming Bundler 2.1 and Bundler 3 releases.

12. It's been a busy year
13. Bundler 1.17
14. Bundler 2
15. Bundler ships with Ruby!
16. Sadly it wasn't all that great
17. Bundler 2 release (The one that broke )
21. It sucked
22. Broke a lot of CI builds
23. Broke default ruby on MacOS
24. Pretty much killed "gem install bundler" on ruby < 2.6
25. Also Pretty much killed "gem install rails" on ruby < 2.6
26. Forced users to run `gem update --system`
28. What happened?
29. Problem 1 gem install bundler
30. $ gem install bundler
31. $ ruby --version ruby 2.2.0p0 (2014-12-25 revision 49005) [x86_64-darwin18] $ gem install bundler Fetching: bundler-2.0.1.gem (100%) ERROR: Error installing bundler: bundler requires Ruby version >= 2.3.0.
32. $ ruby --version ruby 2.4.6p354 (2019-04-01 revision 67394) [x86_64-darwin18] $ gem --version 2.7.9 $ gem install bundler Fetching: bundler-2.0.0.gem (100%) ERROR: Error installing bundler: There are no versions of bundler (= 2.0.0) compatible with your Ruby & RubyGems bundler requires RubyGems version >= 3.0.0. The current RubyGems version is 2.7.9. Try 'gem update --system' to update RubyGems itself.
33. $ gem install bundler -v '~> 2.0'
34. Problem 2 Version auto switcher
35. $ bundle _1.17.2_ install
36. $ bundle install
37. $ grep -A 1 "BUNDLED WITH" Gemfile.lock BUNDLED WITH 1.17.3 $ bundle version Bundler version 1.17.3
38. $ grep -A 1 "BUNDLED WITH" Gemfile.lock BUNDLED WITH 2.0.1 $ bundle version Bundler version 2.0.1
39. Managed by RubyGems
40. Bundler Version Finder
41. Filters possible versions of Bundler that can be activated by RubyGems
42. RubyGems 3 Matches on major version (Same as Bundler 1) BUNDLED WITH 2.0.1 Bundler Versions 2.0.1 2.0.2 2.1.0 3.0.pre.1 1.17.2
43. Different rules between RubyGems v2 - v3
44. RubyGems 2 Matches on exact version BUNDLED WITH 2.0.1 Bundler Versions 2.0.1 2.0.2 2.1.0 3.0.pre.1 1.17.2
45. Can't find gem bundler (>= 0.a) with executable bundle (Gem::GemNotFoundException) RubyGems 2 bug
46. This is why Bundler 2.0.0 depended on RubyGems 3
47. BundlerVersionFinder was first written during a very different time and ideas
49. $ gem update --system
50. Why didn't Bundler 2 just read the bundler 1 lockfile?
51. Breaking changes
52. Have bundler manage it's own version
54. Problem 3 Communication
56. Discussions were in open channels but were not easily available
57. Move all decisions to Github
58. Improving future releases
59. Ideas for a better major release • Actively engage for feedback from the community • Longer pre release cycles • More transparency around breaking changes
