Hello,

After porting some old PHP scripts to Ruby, I'm now having strange 
problems with the Ruby 'require' and 'include' mechanisms under 
Apache/1.3.28, mod_ruby/1.2.4 and ruby/1.8:

We run several virtual hosts on one machine, each has a structure like this:

file: /rb/tools.rb

   module name_of_host  # to avoid namespace collisions
       def a ()
           # ...
       end
   end

file: /subdir/rb/tools.rb

   module name_of_host_subdir
       require '../rb/tools.rb'
       include name_of_host
       def b ()
           # ...
       end
   end

file: /subdir/language/index.rhtml

   <%
   require '../rb/tools.rb'
   include name_of_host_subdir
   a()
   b()
   %>

I get errors like this on Apache restart:

/.../subdir/language/index.rhtml:3: warning: main#include in the wrapped 
load is effective only for toplevel

And then HTTP requests produce errors like this:

/.../subdir/language/index.rhtml:3: uninitialized constant 
#<Module:0x40560f5c>::name_of_host_subdir (NameError)
   from (eval):117
   from /.../eruby-run.rb:116:in `eval_string_wrap'
   from /.../eruby-run.rb:116:in `run'
   from /.../eruby-run.rb:72:in `handler'

/.../subdir/language/index.rhtml:4: undefined method `a' for main:Object 
(NoMethodError)
   from (eval):117
   from /.../eruby-run.rb:116:in `eval_string_wrap'
   from /.../eruby-run.rb:116:in `run'
   from /.../eruby-run.rb:72:in `handler'


I know that my problem is closely related to this 
<http://lists.modruby.net/ml/archive/modruby/200404.month/1161.html>, 
and I've tried the suggested patch to Ruby eval.c from Shugo 
<http://lists.modruby.net/ml/archive/modruby/200404.month/1162.html>, 
but it didn't solve the problem.

Here are the relevant entries in httpd.conf:

LoadModule ruby_module        libexec/mod_ruby.so
AddModule mod_ruby.c

<IfModule mod_ruby.c>

  RubyRequire apache/ruby-run
  RubyRequire apache/eruby-run

  RubySafeLevel 2
  RubyTimeOut 60

  <Files *.rbx>
    SetHandler ruby-object
    RubyHandler Apache::RubyRun.instance
  </Files>

  <Files *.rhtml>
    SetHandler ruby-object
    RubyHandler Apache::ERubyRun.instance
  </Files>

</IfModule>


Thanks in advance for any helpful information.

Simon
