Question

I’ve built a code which vote for me on a website…

The Ruby script works quite well but after few minuts this script stop with this errors : link of the screen-shot

So I’ve inspected the windows task manager and the memory alocate to the ruby.exe grow after each loop !

here is the incriminate peace of code :

class VoteWebsite
        def self.main
        agent = Mechanize.new
        agent.user_agent_alias = 'Windows Mozilla'
    while $stop!=true
        page = agent.get 'http://website.com/vote.php'
        reports_divs = page.search(".//div[@class='Pad1Color2']")
        tds = reports_divs.search("td")
        i = 3;j = 0;ouiboucle=0;voteboucle=0
        while i < tds.length
            result = tds[i].to_s.scan(/<font class="ColorRed"><b>(.*?) :<\/b><\/font>/)
            type = result[0].to_s[2..-3]
            k=i
            case type
            when "Type of vote"
                j= i+1;i += 4
                result2 = tds[j].to_s.scan(/<div id="btn(.*?)">/)           
                id = result2[0].to_s[2..-3]
                monvote=define_vote($vote_type, tds[k].to_s, $vote_auto)
                page2 = agent.get 'http://website.com/AJAX_Vote.php?id='+id+'&vote='+monvote
                voteboucle+=1
                .
                .
                .
            else
                .
                .
                .
            end
        end     
    end
    end
end
VoteWebsite.main

I think that declaring all the variables inside the method to Global variable should fix this probleme but the code is quite big and there is planty of variables inside this method.

So is there any way (any Ruby instruction) to drain all this variable at the end of each loop ?

Answer 1

The problem came, in fact, from the history of mechanize see this answer or the Mechanize::History.clear method or even just set the Mechanize::History.max_size attribute to a reasonable value.

#!/usr/bin/env ruby

require 'mechanize'

class GetContent
    def initialize url
        agent = Mechanize.new
    agent.user_agent_alias = 'Windows Mozilla'
    agent.history.max_size=0
    while true
            page = agent.get url
        end
    end
end

myPage = GetContent.new('http://www.nypost.com/')

hope it helps !
