<br> Reporter: Rhett Sutphin
<br> Priority: Minor
<br><br><br>Hash#each_pair behaves differently when you add new keys to the hash during iteration on JRuby 1.4.0 and MRI 1.8.7p174. This gist contains a short script which illustrates the different behaviors:
<br><br><a href="http://gist.github.com/243048" target="_top" rel="nofollow">http://gist.github.com/243048</a><br><br>JRuby 1.4.0's behavior is the same as Ruby 1.9.0, not 1.8.7.
<br><br>I don't know how important this difference is -- the 1.8 line's behavior is inconsistent (it seems to be dependent on the iteration order of the pairs), so it would be tricky to be deliberately depending on it. On the other hand, we did run into it in production code: a colleague of mine noticed the problem when executing a method which recursively converted all the keys in a hash to symbols (in place). On MRI 1.8.x, this method would complete, but not on JRuby 1.4.0. (It was trivial to convert this method to a form that would work in both places.)
<br><br>I attempted to write a RubySpec for this, but since the 1.8 behavior doesn't seem deliberately designed, I wasn't sure how to go about it. I will update this ticket if I make any progress.

<br><a href="http://netbeans.org" target="_top" rel="nofollow">http://netbeans.org</a>. We still use warbler to package our web app into a

<br><br>I just gave a presentation on JRuby on Rails at JRubyConf last Sunday,
<br>and I'd like to assure you that keeping Rails running well on JRuby is
<br>indeed a high priority. The Rails and JRuby teams will be working

<br>were recorded too.
<br><br>Cheers,

</div></div>The actual annotations don't need a reference to a class, but perhaps<br>
we need to open up a way to refer to a class in an annotation even<br>
though the actual class is not defined yet. Ideas on how we could do<br>
that? Maybe a way to pre-tag a Ruby class with its fully-qualified<br>
java class name and pass a Ruby class in? We could then use that name<br>
when reifying the class, so that we don't have to dump everything in<br>
the "ruby.*" package.<br>

<br><br>I had run into the same problem while upgrading to ruby 1.8.7 with the same rails platform. There are 2 things you can do:
<br><br>1) Include the mb_chars class as a plugin into Rails 1.2.6
<br>2) Remove the ruby chars implementation
<br> In your environment.rb add:
<br>Unless '1.9'.respond_to?(:force_encoding)
<br> String.class_eval.do
<br> begin
<br> remove_method :chars
<br> rescue NameError
<br> #No prob!
<br> end
<br>end
<br><br>The first will require more work but is a better bet from a future migration perspective and that's what I've done. You will also need to change all chars calls to mb_chars.
<br><br>Regards
<br>Varun

<br><br>I can see that the full table name is being passed down to the JdbcConnection in the JdbcAdapter. I recently upgraded from rails 2.0.2 where this code worked without a problem. Any ideas? Will the change to RubyJdbcConnection.java fix it? And if so, is it planned as part of a new version?

<br><br>I haven't found a definition for new_date(). If my code hits that line, I

<br>I think, the code as in the oracle_enhanced adapter is safer (as I also had

<br> value.respond_to?(:hour) &&

<br><br>Sure, I will do including a patch against the files from 0.9.2.

<br>This was fixed in 19176f8188bef2786b1e3ec49dcff04f408cdee8, but the patch was incomplete and made instances of the reified class turn into null when passed to java code.

<br> Issue Type: Bug
<br> Affects Versions: JRuby 1.4

<br> Reporter: Jeremy Stephens
<br> Assignee: Thomas E Enebo
<br> Priority: Minor
<br> Fix For: JRuby 1.5
<br> Attachments: test.rb
<br><br>The 'next' command in ruby-debug in JRuby behaves like the 'step' command. That is, it steps into the next statement rather than skipping over it.
<br><br>Attached is a test file used with rdebug (jruby -S rdebug test.rb).
<br><br>The problem goes away when the --debug flag is passed to JRuby. Should rdebug automatically include the --debug option?
