[ANN] JRuby 1.6.0.RC2 released

The JRuby community is pleased to announce the release of JRuby
1.6.0.RC2.

JRuby 1.6.0.RC2 is the second release candidate of JRuby 1.6.0.

JRuby 1.6.0 is the largest release of JRuby to date. This release
fixes hundreds of user issues and brings compatibility with Ruby 1.9.2
to a very high level. We have made Windows a primary supported
platform by adding it as a continuous integration platform, and JRuby
1.6 will provide Windows-based Ruby users with the best experience
yet. This release integrates experimental support for C extensions
based on Ruby’s C API. And as with all major releases, we have
improved stability and performance across the board in response to
real-world user input.

We encourage Ruby and JRuby users alike to test out 1.6.0.RC2 to help
us shake out remaining issues. It would be especially helpful if users
would test out 1.9 mode (by passing --1.9 flag) to help us round out
our 1.9.2 compatibility before the final 1.6.0 release.

Notable changes since 1.6.0.RC1:

  • Large number of 1.9 compatibility issues addressed
    • Encoding issues (especially involving Regexp)
    • Fiddle implementation
    • non-ASCII identifiers
  • irb (1.8.7, 1.9.2) and command prompt added to Windows installer
  • Compiler handles all 1.9 syntax now
  • Fixes for new backtrace accuracy, reliability
  • Removed all GPL or LGPL-only dependencies
  • Updated to RubyGems 1.5.0
  • C extension support prebuilt for OS X, Linux (32/64), Windows (32)
  • 83 issues resolved since RC1

Major Features:

  • Ruby 1.9.2 language and API compatibility

    • Not implemented Encoding::Converter, ripper
  • Improved Ruby call performance

  • Built-in profiler (–profile, --profile.graph)

  • RubyGems 1.4.2

  • RSpec no longer bundled

  • C Extension support (experimental)

  • RubyGems Maven support (preview)

  • Improved compatibility and user experience on Windows

  • jruby-complete.jar now includes 1.9 standard library

Thanks very much. My favourite Ruby for some time now.

platform by adding it as a continuous integration platform, and JRuby

Congratulations on this release and your hard work.

1.6.0-RC2 works fine here on my systems (several codes using
xml/jdbc/ramaze in 1.9 mode mostly)

It seems coverage is not included in the C extensions ? Trying to use
back simplecov gave me this output:

org/jruby/RubyKernel.java:1047:in `require19’: no such file to load –
coverage (LoadError)

Is there a tutorial somewhere on how to compile and include manually
such extensions ? Basically this would be equivalent I guess to
compile coverage.c into coverage.so and include it in a specific
location for windows, no ?


Christian

back simplecov gave me this output:

org/jruby/RubyKernel.java:1047:in `require19’: no such file to load –

Did you install the gem?
Also if it uses an event hook, I’m not sure if jruby does those yet :slight_smile:

  • JRUBY-4907 popen4 reports wrong PID on Windows

Thank you much for fixing this bug, and also 2706, the two that I most
remembered! :slight_smile:

Also I was wondering if this one could be addressed:

http://jira.codehaus.org/browse/JRUBY-5135 (make jruby.launch.inproc
false by default)

before 1.6 shipped. That would be swell.

Thanks. Liking jruby more and more these days, and it’s my go-to for
GUIs and windows multi-threaded apps now :slight_smile:

yes I did install simplecov gem. To me coverage.so is an extension in
MRI, so I expect it to be also a java extension or C extension for
jruby.

Unfortunately, it did not make it yet in the jruby-1.6. This is why I
asked yesterday how to include it manually…

Also if it uses an event hook, I’m not sure if jruby does those yet :slight_smile:

I do not know why event hooks are involved here. I’ll try to google
for more docs on extensions in jruby.


Christian

I’m not sure if jruby has an equivalent to coverage.so or not. If it
doesn’t then you could file a JIRA for it :slight_smile:

It does have some other profiling options that apparently are more
full-fledged in 1.6.0, dunno about coverage.

-r

Notable changes since 1.6.0.RC1:

  • irb (1.8.7, 1.9.2) and command prompt added to Windows installer

As a note, the command prompt doesn’t seem to work properly for me
(doesn’t add jruby to the path…and its default directory is
C:\WINDOWS\system32 for some reason, and the icon doesn’t seem right,
either)

Yes, Ruby 1.9 added several native libraries that we have not ported.
I just added “fiddle” immediately before RC2, and by my count the
following libraries remain unimplemented in JRuby:

continuation
coverage
curses
dbm
dl (though we have a partial port atop FFI)
fcntl (some there, but parts missing, I think)
fiber (note this is the additional continuation-like fiber stuff)
gdbm
objspace
pathname (we still use .rb version, I believe)
pty (we have a partial impl in FFI, I think)
racc
ripper
sdbm
syslog (partial impl in FFI)
tk

Of these, objspace and ripper are very MRI-specific, continuation and
fiber are not possible on the JVM currently, and several others
require specific native libraries like Tk.

The “coverage” library might not be difficult to implement, since rcov
works fine with JRuby. A similar mechanism could be ported to core
JRuby and used to provide the “coverage” extension’s features. That
said…it’s not a high priority, since rcov works fine.

We welcome any and all takers who’d like to implement the above
extensions (and you can implement them in Ruby, if you like).

Do you not let the installer setup the path for you? Maybe we need to
add some more logic for that. An option is passed to cmd which is
supposed to set the default directory to what install4j thinks is your
home directory (which works for me in Win 7).

More info:

  1. Windows OS
  2. Home directory location (perhaps this is a space issue – windows 7
    does not have spaces to home)

seemed to fail for me in both XP and 7, same way.

with XP just now, installed it to (unchecked “set path for me”)
D:\installs\jruby-1.6.0.RC2\bin
and the icon is wrong, dir is wrong, jruby\bin not in path.
Thanks!

  • Charlie

according to the original author of coverage.so in MRI, it cannot be
done in pure ruby (I already asked him). I can have a look at coverage
in jruby.

Are there any pointers/tutorials on how to integrate new extensions ?
And could you please give me the commit sha1 for your “fiddle” latest
extension so I could figure out the details ?

Thanks


Christian

Also I was wondering if this one could be addressed:

http://jira.codehaus.org/browse/JRUBY-5135 (make jruby.launch.inproc

Any chance of getting some looks at this one?

Also could we remove jruby.bat finally, now that jruby.exe is solidly in
place :slight_smile:

-r

You did not answer this question…I can try it on my machine if I
can figure out how to set my windows home to not be c:/Users/enebo.
Not sure I can and I am not sure I should tempt Windows either :slight_smile:

If I remember correctly, on win 7 it does not have a space, on XP it
does (they both fail).

Just for clarification…when you originally installed this did you
have set path for me unchecked as well? I am on win 7 and this works
fine for my when the path is setup for me.

always unchecked.

I did notice that in win7, the cwd is %homepath%, in xp, it is
c:\windows\system

Thanks!

I will figure out how to explicitly set the path when path is not set
(well I will probably just unconditionally set it).

and the icon is wrong, dir is wrong, jruby\bin not in path.
