Environment

Provide at least:

  • JRuby version (jruby -v) and command line (flags, JRUBY_OPTS, etc)
version: jruby 9.1.16.0
JRUBY_OPTS="--server -J-Xms512m -J-Xmx1024m"
  • Operating system and platform (e.g. uname -a)
Distributor ID:	Ubuntu
Description:	Ubuntu 14.04.5 LTS
Release:	14.04
Codename:	trusty

Other relevant info you may wish to add:

  • Installed or activated gems: mongo
  • Application/framework version (e.g. Rails, Sinatra): Nothing.
  • Environment variables

Expected Behavior

  • Describe your expectation of how JRuby should behave, perhaps by showing how CRuby/MRI behaves.
  • Provide an executable Ruby script or a link to an example repository.

Errno::ENOMEDIUM::Errno object exists.

Actual Behavior

raise SystemCallError.new('Test error', Errno::ENOMEDIUM::Errno)

I got NameError: uninitialized constant Errno::ENOMEDIUM
https://api.travis-ci.org/v3/job/406430973/log.txt

I did grep on HEAD of master branch. Then I could not find the implementation.

$ grep -r 'Errno::ENOMEDIUM' *

I compared the result of Errno.constants between Ruby 2.5.1 and JRuby 9.1.16.0 on my local environment (Fedora 28).

Ruby 2.5.1: https://gist.github.com/junaruga/9f455234c81cff7580b0ffd65085fb8d
JRuby 9.1.16.0: https://gist.github.com/junaruga/cbd781907d7c7b282f90d36b5cdd0ce7

Some of the Errno codes are not included in the JRuby.

The constants for Errno come from the https://github.com/jnr/jnr-constants project, and JRuby just generates from there. These additional constants should be added there with reasonable defaults and the files regenerated on supported platforms. Maybe you can help us there?

@headius Thanks for the information! As I usually do not use Java now, I would like to delegate someone for the help.

@headius I fixed this and some other missing parts https://github.com/jnr/jnr-constants/pulls

should I regenerate them too? If so, let me know.

I believe this was fixed by jnr/jnr-constants#46 which seems to be the last time we regenerated the Linux constants. That would have been included in JRuby 9.1.14.0 at least.
