Having learned my lessons from previous Vista-XP incompatibility, this time I built and tested on both platforms.
For me, ant test passes on both Vista and XP. Also ant run-junit-interpreted passing.

In fact, I tried on 3 different XPs, and it works fine on all of them. Revision 6011, WinXP (with latest updates), Java 1.6.

Very strange.

Finally, I was able to reproduce this problem, but only if I explicitly disable native extensions:

C:\work\jruby-dev\jruby>jruby -J-Djruby.native.enabled=false test/test_io.rb -n test_copy_dev_null
Loaded suite test/test_io
Started
E
Finished in 0.68 seconds.

  1) Error:
test_copy_dev_null(TestIO):
Errno::ENOENT: No such file or directory - No such file or directory - C:/work/jruby-dev/jruby/NUL:

So, the question is why native wasn't enabled by default in some cases???
Bill, Robert, do you have anything special about your XP? Is it Home or Professional? Is Service Pack 2 installed?

Anyways, we should fix JRuby behavior when Posix extensions are not available.

Simlest example that shows the problem:

jruby -J-Djruby.native.enabled=false -e "p File.stat('NUL:')" =>

-e:1: No such file or directory - No such file or directory - C:/work/jruby-dev/jruby/NUL: (Errno::ENOENT)

I get this on both my home and work Windows machines. My environment:

Windows XP Professional, version 2002, SP 2 (both)
Java 1.6.0_03-b05 (Home)
Java 1.6.0_02-b05 (Work)

Where do we look for native extensions? Could it be an issue with Path or some other environment variable?

My understanding is that JRuby uses native libraries via JNA, and it shouldn't be dependent on PATH. I'll check with Tom as the JNA/POSIX guru

Meanwhile, can you add -J-Djruby.native.verbose=true command line when you start JRuby? Do you see any output? For me, I see: Successfully loaded native POSIX impl.

Maybe you'll see some additional info on why native POSIX isn't loaded for you by default?

I do get the "Successfully loaded native POSIX impl." message. Very strange.

I have Windows XP Pro, 32-bit, SP2 installed, fully patched; Java 1.5.0.11.

Here's what I see:

C:\home\temp\foo\jruby>jruby -J-Djruby.native.verbose=true -e "p File.stat('NUL:')"
Successfully loaded native POSIX impl.
-e:1: No such file or directory - No such file or directory - C:/home/temp/foo/jruby/NUL: (Errno::ENOENT)
C:\home\temp\foo\jruby>java -version
java version "1.5.0_11"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_11-b03)
Java HotSpot(TM) Client VM (build 1.5.0_11-b03, mixed mode, sharing)

C:\home\temp\foo\jruby>

I have c:\home\temp\foo\jruby\bin in my PATH, and I get identical behavior with JRUBY_HOME undefined and set.

I had the suspicion it had something to do with the fact that POSIX paths starting with a '/' are absolute. Thus, /dev/null always points to the right thing. With NUL: being a rather foreign notion to POSIX, it tries to apply it to the working directory and falls over dead.

FYI, this still fails with a fresh checkout from trunk at r6485 (with JRUBY_HOME set and prepended to Path; otherwise, failure occurs in test_argf->test_argf_sanity).

All tests, including this one, should currently be passing on Windows.
