Subject: [Yarv-devel] yarv-0.2.1 errors with dbi
Message-ID: <c54bb53a18c820571ffcf361604c2d53@ghostgun.com>

I get two different errors depending on which directory I'm in

not in yarv source directory
$ ~/bin/ruby -rite ~/flowmeter-rb/flowmeter.rb
/home/jeffm/bin/ruby: No such file to load -- ite (LoadError)

in yarv source directory

$ ~/bin/ruby -rite ~/flowmeter-rb/flowmeter.rb
/home/jeffm/lib/ruby/site_ruby/1.9/dbi/row.rb:157: [BUG] Segmentation 
fault
ruby 1.9.0 (2005-03-04) [i686-linux]

Aborted

If I add a -I <path-to-yarv> get the [BUG] error likewise if I add -I 
~/lib/ruby/site_ruby/1.9/i686-linux/. yarvcore is located in 
/home/jeffm/lib/ruby/site_ruby/1.9/i686-linux/yarvcore.so and $: is

$ ~/bin/ruby    -e 'puts $:'
/home/jeffm/lib/ruby/site_ruby/1.9
/home/jeffm/lib/ruby/site_ruby/1.9/i686-linux
/home/jeffm/lib/ruby/site_ruby
/home/jeffm/lib/ruby/1.9
/home/jeffm/lib/ruby/1.9/i686-linux
.

I used the eval patch included in yarv-0.2.1 and I installed yarv. Is 
this path problem fixed in the subversion version or did I miss 
something?

The [BUG] error refers the the last line of row.rb which only contains

end # module DBI

without the -rite option this script functions as expected.

Any thoughts on either of these problems?

Jeff.

Hi,

I released YARV 0.2.2 (8-8 release).

Changes:  http://www.atdot.net/svn/yarv/trunk/Changes

At next release (9/9), I'll merge YARV with Ruby interpreter (not with
official CVS head, but with local copy of latest ruby).

Without the -rite option, normal ruby (without yarv) will run.
The "-rite" options means "require 'ite.rb'"

And [BUG] should be YARV's bug...

Ah, copying ite.rb to ~/lib/ruby/site-ruby/1.9 fixes the required 
problem. Obvious when you think about, but I wasn't sure if you'd 
expanded the command line options of ruby. Should have known better. 
Why make life difficult by creating unnecessary work for yourself. This 
just leaves one question: Is it possible to trigger a backtrace on such 
a bug? I gather 'not yet' from the discuss in another thread (only 
glanced through it).

On the good news front, yarv loads my c based module which uses the 
flow-tools library and runs correctly.

Jeff.

Hi,

I'm very glad to announce the release of YARV 0.3.0.

This version includes Ruby source code (2005-08-13) and merged with
YARV.  So you can experience Rite :)  For example, you can't find
"rb_eval()" in "eval.c".


Homepage: http://www.atdot.net/yarv/
tar ball: http://www.atdot.net/yarv/yarv-0.3.0.tar.gz


Limitations:
* only "miniruby" was built
* no "ext/" libraries
* no "lib/" libraries
* no thread support
* no many many schemes
* many legacy codes are remained

Hi,

YARV 0.2.3 was released some days ago. It was minor version up to
support current ruby head.

... But maybe no one need it.

Very nice! It's good to see a merged version of the source.

I had to apply the patch below to get it to compile on Mac OS 10.4,  
gcc 3.3:

diff -ru yarv-0.3.0/error.c yarv/error.c

int ruby_nerrs;
/* TODO */
-int ruby_in_eval;

}

make test then runs successfully


See http://arton.no-ip.info/diary/20050816.html for the original  
error - you'll understand the page better than I do!

Ha! Seems already to be fixed in rev 248. Should have checked first -  
sorry for the noise.

The results of some more ByteCodeRuby test mining - 6 new tests for  
massign, a couple of them pretty obscure. 3 pass, 3 fail - the  
failures have separate test methods.
