Ruby 2.5.7 support

[timolehto]

Updating our ruby version, but now with actions our CI is unable to use the latest 2.5.x Ruby to run tests etc.

https://www.ruby-lang.org/en/news/2019/10/01/ruby-2-5-7-released/

Same here. Are there timelines from the time of release to the availability of ruby versions?

[shrmnk]

So Github just announced that Actions will be GA on 13 November, anyone able to chime in on whether this will be available by then?
Can't imagine people moving their CI workflows into Actions then finding out month-old releases are not even available (edit: 3-month old releases aren't available either)

I need ruby 2.6.5, and unless we can get support for that then unfortunately it's a no-go from the offset. I think this is going to be a pretty ubiquitous requirement for any serious app. 🙏

Hej! I built https://github.com/clupprich/ruby-build-action over the weekend, which makes use of ruby-build to install exactly the version of Ruby you need.

While that sounds (and actually is) slow, you can use the actions/cache action to cache the Ruby installation in your workflows (which brings the time it takes to setup Ruby down to ~30 seconds).

Let me know if that works for you. Feeback/issue reports/contributions welcome!

@clupprich That absolutely solved this for me, and I imagine it will do so for many others! Great job.

Thanks @clupprich...that worked perfectly! Not sure how useful setup-ruby is when you can't specify the exact ruby version you need.

Not that everyone is testing on Windows, but I created MSP-Greg/actions-ruby, which installs current Ruby versions (along with ruby-head/master) and allows updating the gcc build tools/packages on Windows.

Ruby 2.3.3 is also available, but if used for extension gems, it compiles with the newer 'DevKit'...

+1 for Ruby 2.5.7 support.

I think this requires an update to the virtual environment, so I’ve requested it here: actions/runner-images#95

What are the currently supported Ruby versions? Our actions started failing today with a similar message, Version 2.5.5 not found.

The support page linked by @konradpabjan in actions/setup-python#15 (comment) still says that Ruby 2.5.5 is supported.

[konradpabjan]

Ruby 2.5.5 should work. Just tested it out:

https://github.com/konradpabjan/Testing3/commit/9561e0ac0a4e7dcd4ab209aa0aacd3e4df02203c/checks?check_suite_id=365213462#step:4:4

Looking at the tools cache where the Ruby gets downloaded from, I still see version 2.5.5. It gets added here and automatically documented: https://github.com/actions/virtual-environments/blob/9786a9946a6db1a8d0c89948550753f9e01007b3/images/linux/scripts/installers/1804/hosted-tool-cache.sh#L39

If there are issues with the documented versions then actions/virtual-environments is the best place to report it.

[u2606]

2.5.5 is working for us again today. Thanks for testing it.

[bryanmacfarlane]

Closing since 2.5.5 is working and there's already a tracking item in virtual-environments.

Note a related issue: #44

[frankieroberto]

2.5.7 is now available, and 2.5.5 has been removed.

See #49 - flushing out ideas

I have a prototype working locally where we download JIT from rvm if it's not already in the VM cache. I will have an experimental ref soon. The plan is to fall back ruby-build after that (which also has the benefits of self-hosted runners). @clupprich - I may pull inspiration from yours and/or you can have a look at my experimental branch. The ADR proposes using factored out caching logic (lib) so the consumer doesn't have to do the caching (probably just a bool option). Note that if self-hosted, it would only be slow the first build.
