mini_racer: BUG?: Bump mini_racer from 0.4.0 to 0.5.0 getting compile errors

I see them in the GitHub Actions as well. Not sure exactly what caused it, but didn’t see an existing issue so reporting

e.g. https://github.com/rubyjs/mini_racer/runs/4174922268?check_suite_focus=true

building against Ruby 2.7.2, heroku buildpack running on the heroku/heroku:18-build image and node 10.15.3

(
  export HEROKU_STACK="18"
  export ruby_version="2.7.2"
  echo "https://heroku-buildpack-ruby.s3.amazonaws.com/heroku-${HEROKU_STACK}/ruby-${ruby_version}.tgz"
  export node_version="10.15.3"
  echo "https://s3pository.heroku.com/node/v${node_version}/node-v${node_version}-linux-x64.tar.gz"

)

stacktrace from circleci

seems to be specific to libv8-node-15.14.0.0 -> libv8-node-16.10.0.0 requires I install node 16.13.0? (nope, that didn’t work)

Is there a fix for this? This is still happening with v0.6.0 as well.

Sorry, I should have read more of the context: https://github.com/rubyjs/libv8-node/issues/5, https://github.com/rubygems/rubygems/issues/3174. The bug lies in rubygems. A fix was merged (https://github.com/rubygems/rubygems/pull/4082), with a second rubygems PR outstanding (https://github.com/rubygems/rubygems/pull/4488).

Despite that second PR not being merged/released yet, simply updating rubygems allows me to successfully install the gem now: 🎉

➜ gem update --system  
[...]

➜ gem --version        
3.3.4     

➜ gem install libv8-node              
Successfully installed libv8-node-16.10.0.0-x86_64-linux
1 gem installed

➜ gem install mini_racer              
Building native extensions. This could take a while...
Successfully installed mini_racer-0.6.1
1 gem installed

Edit: Bundler still uses the wrong version - hence the second PR

This isn’t a bug in mini racer or in Heroku. This is a bug in bundler.

Make sure you run:

bundle lock --add-platform x86_64-linux

Then add the results to git before you try to deploy again. Previously bundler would raise an error if you tried deploying to a linux target without the linux platform locked. It looks like there’s been a regression and that error is no longer raised. If that error still existed it would prevent this problem from happening as it wouldn’t even let you try to bundle install without the correct platform being listed.

I’m going to try creating a fat gem which includes both linux and linux-musl libs (which I don’t quite like since it doubles the gem size, but even when I get to fix the root rubygems/bundler issue old versions of these would still be affected)

@lloeki thanks so much for all the work you’ve done here. Like I asked on the other repo, is there anything I can do to help fix this? It’s not fair to put all this on you but I’m not sure on what needs to be done or how I can help.

@tsugimoto I saw #218 but since it’s a different error, I wasn’t confident it was the same issue, even if the result is the same. Thanks for cross-linking though

A lot of related issues were solved by updating Rubygems and bundler and making sure the the right platforms are added to Gemfile.lock (via bundle lock --add-platform)

Correct, but also, make sure to remove any platform-mismatched gem that may have been erroneously installed previously, otherwise bundler may be lazy and pick those up instead of hitting rubygems.org again. In some cases bundler was being stubborn and I’ve had to install the gem first with gem install, then proceed with bundle install.

From my understanding the outstanding rubygems issue/PR is about supporting multiple libc variants at the same time

It would indeed, but it should also helps in some corner cases e.g:

a) one created the lockfile on another platform than linux and did not run bundle lock --add-platform b) one is on either linux (gnu) or linux-musl and the lockfile does not exist yet c) a linux-musl gem on linux (gnu) cannot work, but could be picked up if it is previously installed for whatever reason

Also got this. But maybe I have something to add: it only happens on Ruby 2.7 and 2.6, not on 3.0.

You’re Fetching and Installing libv8-node 16.10.0.0 (x86_64-linux-musl), so I suppose it’s likely a duplicate of #218
