SystemStackError: stack level too deep

my code is ;

$ssf
def find_class(class_name, stack = [])
  FileClass.find(:all, :conditions => ["class_name = ?",
class_name]).each do |file_class|
      FileInclude.find(:all, :conditions => ["file_name = ?",
file_class.file_name]).each do |file_include|
        FileClass.find(:all, :conditions => ["file_name = ?",
file_include.file_name]).each do |xxxx|
          next if stack.include?(xxxx.class_name)
            begin
           find_class(file_class.class_name, stack)

              p  file_class
              p "============================"
              p file_include
              p "^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^------"
              p xxxx
            rescue SystemStackError => ssf
              p $ssf = ssf
            end

        end
      end
    end
  end

Well you seem to be recursing in a pretty uncontrolled way.

Re: SystemStackError: stack level too deep

You have not mentioned how should recursion stop properly. Anyway, code also
doesnt look very clean and I think not very efficient too. My suggestion is
first fetch all FileClass using conditions in an array, include all the
FileInclude as well (using :include) Then select, reject the record you want
to.

Sorry, if I haven''t understood your problem correctly.

sorry, my code is not good one, but the code is here,

  def find_class(class_name, stack = [])
   puts(("\t" * stack.size) + class_name)
#   puts(("\t" * stack.size) + "#{class_name}")
   stack.push class_name
    FileClass.find(:all, :conditions => ["class_name = ?", 
class_name]).each do |file_class|
      FileInclude.find(:all, :conditions => ["file_name = ?", 
file_class.file_name]).each do |file_include|
        FileClass.find(:all, :conditions => ["file_name = ?", 
file_include.file_name]).each do |file_class|
          next if stack.include?(file_class.class_name)
         find_class(file_class.class_name, stack)
        end
      end
    end
   stack.pop
  end

I am testing which part is getting error..

could you provide a simple example for this(using :include), please!

thanks,
 I improved my code, but still not enough
its giving me double result

    stack.push class_name
    FileClass.find(:all, :conditions => ["class_name = ?", 
class_name]).each do |file_class|
      p file_class.file_name + "aaa"
      FileInclude.find(:all, :conditions => ["file_name = ?", 
file_class.file_name]).each do |file_include|

          p file_include.include_file_name + "bbb"
          FileClass.find(:all, :conditions => ["file_name = ?", 
file_include.file_name]).each do |file_class|

          p file_class.class_name + "ccc"
          next if stack.include?(file_class.class_name)

          find_class(file_include.include_file_name, stack)

Re: SystemStackError: stack level too deep

I am trying to recursive call. An the resut should be like this

resullts
------------
 CTAgentHome
          FWCTBase.h
                    FWMOBase.h
                           MOSAgentBasicInfo.h
                                          MOSAgentMessageInfo.h

I am tring to find CTAgentHome''s include classes.
I think it is clear now.

Re: SystemStackError: stack level too deep

I think the problem is you are using the wrong algorithm to solve your 
problem.

DFS (depth-first-search) algorithms will easily repeat sequences across 
subtrees.

Starting at CTAgentHome:
CTAgentHome.h and CTAgentHomeRep.h both share the same [FWMOBase.h, 
MOSAgentBasicInfo.h, MOSAgentCriteriaInfo.h, 
MOSAgentInfo.hMOSAgentMessageInfo.h] subtrees.

By the time you''re back processing CTAgentHomeRep.h at level aaa, none 
of those class_name''s previously seen exist on the stack anymore, so
the
new recursive path doesn''t know that they''ve already been
logged.

Or I really don''t grok your code, and I haven''t had nearly
enough coffee
today.
