Let's say I have the following threading in my Rails web application:
class MyController
def my_action
count = 0
arr = []
10.times do |i|
arr[i] = Thread.new {
sleep(rand(0)/10.0)
Thread.current["mycount"] = count
count += 1
}
end
arr.each {|t| t.join; print t["mycount"], ", " }
puts "count = #{count}"
end
end
As you can see, the 'count' variable is shared across all threads.
**Now,** what I want to do is **share 'count'** across multiple httpd
requests and **allow my_action in MyController to have access to that
variable**. For instance, maybe whatever spawns the ruby process to
serve httpd process could hold the variable count in its scope, and then
the ruby processes spawned for httpd processes could then access that
variable.
Using memcached, a database, and session variables is out of the
question. Ultimately 'count' will actually be a resource object...an FTP
connection.
Is this possible? Perhaps using Apache/Passenger workers like at
http://stackoverflow.com/questions/4471680/a-way-to-access-common-ftp-connection-resource-pool-in-ruby-across-ajax-calls/4471758#4471758?
Example code would be appreciated.
