Drop support for MRI 2.1 #5990

Drenmi · 2018-06-12T06:42:33Z

MRI 2.1 has been EOL for over one year. Time to drop official support? 🙂

Before submitting the PR make sure the following are checked:

Wrote good commit messages.
Commit message starts with [Fix #issue-number] (if the related issue exists).
Feature branch is up-to-date with master (if not - rebase it).
Squashed related commits together.
Added tests.
Added an entry to the Changelog if the new code introduces user-observable changes. See changelog entry format.
The PR relates to only one subject with a clear title
and description in grammatically correct, complete sentences.
Run rake default or rake parallel. It executes all tests and RuboCop for itself, and generates the documentation.

guess you still need to check for MRI

Seems like it. 🙂

I totally agree that dropping support for Ruby 2.1 form runtime, but I'm not sure we should drop it from the target ruby versions.

We will be able to use new Ruby features by dropping support for old Rubies. I think it is a very big advantage. And RuboCop users can use RuboCop only with new Rubies. For example, users can disable RuboCop with Ruby 2.1 on Travis CI by the build matrix feature.

However, personally I think dropping it from target ruby versions hardly has advantages for us. We can use new Ruby features without dropping.
And probably RuboCop users will retire updatung RuboCop by this change. Especially many libraries support old Rubies unfortunately. So libraries owners will not be able to update RuboCop by this change. I think it is a big disadvantage.

I got the same comment from a library owner when we dropped Ruby 2.0.

I don't watch all issues of RuboCop recently because I'm busy. So sorry if you have discussed the comment already.

Drenmi · 2018-06-12T08:27:04Z

It is a bit of a pet peeve on mine, having the community invest effort into enabling people to stay on old, insecure rubies, especially when upgrading Ruby (post 1.9) is relatively trivial. It's a disservice, if anything.

However, I think it's ultimately a question about what RuboCop's official standpoint should be. Will defer to @bbatsov to make the decision. 🙂

bbatsov · 2018-06-12T08:47:50Z

Btw, technically speaking 2.2 has reached it's EOL as well. :-)

I generally share @Drenmi's view on this, but I also realize that just keeping the parsing support around is not that big of a deal, so I'm fine with this.

I'll leave this open for a few days to see what other users & contributors think and I'll make the decision then. (plus I want to cut a bugfix release in the mean time)

Drenmi · 2018-06-12T08:49:47Z

Technically speaking 2.2 has reached it's EOL as well.

Yeah. It's a bit unclear. I think the page might not be updated regularly, so it still says "scheduled for 2018-03-31". 😅

bbatsov · 2018-06-12T09:14:37Z

Yeah, that's a good point as well. OK, let's focus on 2.1 only then. :-)

mikegee · 2018-06-12T18:40:04Z

lib/rubocop/config.rb

+    # 2.2 is the oldest officially supported Ruby version.
+    DEFAULT_RUBY_VERSION = 2.2
+    KNOWN_RUBIES = [2.2, 2.3, 2.4, 2.5].freeze
+    OBSOLETE_RUBIES = { 1.9 => '0.50', 2.0 => '0.50', 2.1 => 0.58 }.freeze


Maybe quote 0.58 too, for consistency?

koic · 2018-06-14T07:59:59Z

The following is preparation for announcement about EOL of Ruby 2.2.
ruby/www.ruby-lang.org#1806.

Apart from that, I understand that this PR focuses on Ruby 2.1 :-)

It is a bit of a pet peeve on mine, having the community invest effort into enabling people to stay on old, insecure rubies, especially when upgrading Ruby (post 1.9) is relatively trivial. It's a disservice, if anything.

FWIW, I agree completely. Especially since rubocop encourages community standards / best practices. Even if this causes a little bit of friction, that's also what a lot of rubocop cops are designed to do in order to help push you in the right direction.

bbatsov · 2018-06-15T17:30:42Z

Well, I've made a decision - let's just go with @Drenmi's original plan. If we manage to nudge more people to upgrade I think that's a good thing (tm) in the end of the day.

This comment is a nitpick. I think that Changes section should be after Bug fixes section 😃

Feel free to reorder this. I don't have a strong preference on the subject, but ideally we should use a consistent ordering in the changelog.

My comment was wrong 💦
Since this item has not been released yet, it has moved to master (unreleased) section with the following commit.
5f70fae

Build is failing because of a missing space. Ideally let's not push to master. 😬

I'm sorry about that. I was not careful in pushing to master branch 😥

I confirmed that it was fixed by the following change.
a073d9a#diff-4ac32a78649ca5bdd8e0ba38b7006a1eR18

As I changed changelog document only, I forgot to run bundle exec rake. The push to master branch should be confirmed more properly locally than open a PR will checked with CI.

I thought that push to master branch was preferable, as far as minor changes (e.g. fix typo, cosmetic change) were concerned, rather than being notified to the watching users by opening a PR. Of course the contents to be reviewed opens a PR. (So, I will open a PR as a basis.)

If pushing to master branch, I pay close attention so that builds can be more securely passed.

Don't worry, @koic. Mistakes happen to everyone. I'm fine with people fixing small things directly on master, I just want everyone to be very careful when doing this.

Here's a late comment. Keyword arguments without defaults were introduced in Ruby 2.1, so I think this example is for Ruby >= 2.1, rather than Ruby < 2.2, i.e., it should be kept.

Sure. I opened a PR #6104.
