jruby-head

@eregon

I just did a PR for a repo that uses the equivalent of 'jruby' and 'jruby-head', which were done with rvm.

Do you hope to generate a 'jruby-head' build in the future? Just wondering, no hurry....

Thanks, Greg

Yes, it's in the plans.
There is already https://github.com/ruby/jruby-dev-builder but no builds there yet.

Which repo is that, and how did you deal with jruby-head there?

Psych. For the time being, I left the workflow using rvm for jruby and jruby-head. See: https://github.com/ruby/psych/blob/master/.github/workflows/ubuntu-jruby.yml

The PR I did was ruby/psych#432, and of course, someone didn't like it.

Thanks for the jruby-head plans. and thanks for all your work with the builds. I don't think the Travis builds were/are tested, at least not fully. So now that yours are, I'm encouraging people to use them.

As you may have seen, I've got actions-ruby allowing ruby-loco mingw and mswin builds to be used. I don't think the ruby-head mingw build you're using runs test-all, and with MRI Ruby, that's a must.

I've always been about master building & testing...

@MSP-Greg I'm looking at having jruby-head on Windows.
However I'm hitting some very strange behavior where tar tf lists bin/jruby.exe, but after tar xf the file is not there! On Linux I can extract and I see it's there. And bin/jrubyw.exe extracts fine.
https://github.com/ruby/jruby-dev-builder/runs/448013601
Any idea what's going on?

I guess I could try to use the .zip instead, but such a major bug in tar on Windows seems surprising. Also using a .tar.gz for all platforms avoids code duplication.
Finally, on .tar.gz release archives of JRuby, I could extract jruby.exe just fine.

When trying with unzip I see:

  inflating: jruby-9.2.10.0-SNAPSHOT/bin/jrubyw.exe  
  inflating: jruby-9.2.10.0-SNAPSHOT/bin/jruby.bash  
  inflating: jruby-9.2.10.0-SNAPSHOT/bin/jirb.bat  
  inflating: jruby-9.2.10.0-SNAPSHOT/bin/ri.bat  
  inflating: jruby-9.2.10.0-SNAPSHOT/bin/jgem  
  inflating: jruby-9.2.10.0-SNAPSHOT/bin/jruby.dll  
  inflating: jruby-9.2.10.0-SNAPSHOT/bin/jirb_swing  
  inflating: jruby-9.2.10.0-SNAPSHOT/bin/jruby.bat  
  inflating: jruby-9.2.10.0-SNAPSHOT/bin/jrubyd.bat  
  inflating: jruby-9.2.10.0-SNAPSHOT/bin/testrb  
  inflating: jruby-9.2.10.0-SNAPSHOT/bin/jruby.exe  
  inflating: jruby-9.2.10.0-SNAPSHOT/bin/jirb  
  inflating: jruby-9.2.10.0-SNAPSHOT/bin/irb.bat  
  inflating: jruby-9.2.10.0-SNAPSHOT/bin/jirb_swing.bat  
replace jruby-9.2.10.0-SNAPSHOT/bin/jruby? [y]es, [n]o, [A]ll, [N]one, [r]ename:  NULL
(EOF or read error, treating as "[N]one" ...)
  inflating: jruby-9.2.10.0-SNAPSHOT/bin/jrubyc.bat  
  inflating: jruby-9.2.10.0-SNAPSHOT/bin/rdoc

Not sure what that means.

Give me a second...

I downloaded it, extracted with 7z GUI, and running jruby --version outputs Cannot find Java 1.5 or higher. which I assume is an error message in the exe file?

Now, why tar is misbehaving, that might take me a few minutes to figure put...

Looks like both tar and unzip have the issue, and they consider two files named jruby and jruby.exe to be the same apparently on Windows? Is that a Windows or filesystem restriction maybe?

I managed to work around by explicitly not extracting bin/jruby (so only bin/jruby.exe).

There's a few tar.exe files on the Actions Windows image. I don't know what node uses, and we're using node for the extraction, right?

Let me check the MSYS tar and see what it does...

Using the MSYS2 tar or the git tar, the below worked. Does that help?

tar.exe -xzf jruby-head.tar.gz

I'm using just tar in the bash shell on Windows.
The command succeeds, but does not extract bin/jruby.exe.

For https://repo1.maven.org/maven2/org/jruby/jruby-dist/9.2.9.0/jruby-dist-9.2.9.0-bin.tar.gz it works fine, probably because jruby is before jruby.exe.

OTOH, for https://oss.sonatype.org/content/repositories/snapshots/org/jruby/jruby-dist/9.2.10.0-SNAPSHOT/jruby-dist-9.2.10.0-20200214.210645-79-bin.tar.gz jruby.exe is before jruby, and it seems tar/unzip consider it should "override/delete" jruby.exe for some reason.

Oddly enough, it was the 2nd file that I used. I never checked to see what Actions uses for Windows bash. Maybe I should do that...

This is messy. I'm working on it.

I think I'm losing my mind. I thought I posted this AM.

Anyway, Windows 10 and the image on Actions both have a Windows tar command. Also, the mv command was doing some odd things.

The following worked, although Windows specific:

- name: Download latest jruby nightly archive
  if: startsWith(matrix.os, 'windows')
  run: |
    $url=$(ruby find-jruby-head-url.rb)
    echo "$url"
    curl --fail -L -o archive.tar.gz "$url"
    C:\Windows\System32\tar.exe -xzf archive.tar.gz
    gci -Path ./jruby-* -Attributes Directory | Rename-Item -NewName jruby-head
    ls jruby-head/bin

Thanks! I'll try that.

So it looks like tar inside the Bash shell misbehaves and does not extract jruby.exe.
Running tar in the default Windows shell works and extracts both jruby and jruby.exe.

FWIW, jruby-head seems currently broken on Windows: jruby/jruby#6073
Maybe I should just make it available on non-Windows first.

Maybe I need to install Java. How would one detect that the Ruby installation is JRuby on Windows?

We found out the root issue, see jruby/jruby-launcher#29 (comment)

Yes. I guess I broke it (ruby/rubygems#2119). Sorry...

EDIT: Reading further, I guess I fixed it in ruby/rubygems#2876.

Running jruby-head, I just did

gem update --system -N

Which seems to have install RG 3.1.2 and Bundler 2.1.2, but it creates binstubs named jgem & jbundle.

The old gem binstub works...

Copied jbundle and jbundle.bat and renamed without j, and all is good.

No worry, my jruby-head builds work now.
Here is the release for setup-ruby: https://github.com/ruby/setup-ruby/releases/tag/v1.17.0
Could you close this issue?

For the record, just mv jruby-10.0.1.0 /c/Users/runneradmin/.rubies/jruby-10.0.1.0 in the Bash shell also makes jruby.exe disappear:
