JRuby Head Broken?

addis_a · February 24, 2015, 8:33pm

Hi, all…I’m helping with the ‘dnsruby’ gem (
https://github.com/alexdalitz/dnsruby), and have been making sure it
runs
on JRuby.

We recently got a Travis CI error running the tests on JRuby head.
Should
we not be including JRuby head in the versions to test with Travis CI?

The page showing the error is at:

https://travis-ci.org/alexdalitz/dnsruby/jobs/51427488

I installed jruby-head using rvm, and whenever I run irb and input
anything, it says:

➜ ~ irb
:001 >
:002 > puts ‘hello’
hello

`script’Maybe IRB bug!

I suspect I should be ignoring jruby-head, expecting it to sometimes be
unstable. Is that the answer?

Thanks,
Keith

This is something I am working on atm. In mixed mode we have a race
which
does not seem to affect any tests we run but I can see it in some more
complicated scenarios. I am trying to get this back this afternoon to
being solid.

Tom -

This isn’t a big deal for dnsruby, but I mention it in case it would be
helpful to you in your troubleshooting…

I just rvm reinstalled jruby-head, and still get an error when running
the
tests, but it’s a different error. No error occurs when using
jruby-1.7.18. You could reproduce it yourself by git cloning
[email protected]:alexdalitz/dnsruby.git, running ‘bundle’, and then ‘rake
test’. Here’s the output:

/Users/kbennett/.rvm/rubies/jruby-head/bin/jruby -I"lib"
-I"/Users/kbennett/.rvm/gems/jruby-head/gems/rake-10.3.2/lib"
