Rails - May 2008 - custom serialization problem (marshal_dump, marshal_load)

Hi,

I have a problem with the marshal_dump and marshal_load...
I built two classes XXX, YYY and implemented both methods like this:

class YYY
   @data = "string"
   @version = 1

   def marshal_dump()
       return [@version,@data]
   end

   def marshal_load(var)
       @version = var[0]
       case @version
            when 1
                @data = var[1]
            else
                #do something else
            end
   end
end

class XXX
   @data = Array of YYY
   @version = 1

   def marshal_dump()
       return [@version,@data]
   end

   def marshal_load(var)
       @version = var[0]
       case @version
            when 1
                @data = var[1]
            else
                #do something else
            end
   end
end

The serialization works correctly when the number of objects YYY is
small, but when it got more than 5000, the serialization doesn''t work.
(the serializaed file has more and less 1 meg)


When I try to not to use marshal_dump and marshal_load. the
serialization works again????

Can someone tell me, where is the difference between customized
serialization and no-customized one???

Thanks you very much

Sayoyo

Asking smart questions, lesson 1. Never say "it doesn''t
work". Do say
exactly what happens and how that differs from what you expected.
