Zombies HTTP connections raise TCP exception

[kremio]

Hello,
I've noticed that after a certain number of queries, the following exception occurs:
Failed to open TCP connection to api.figo.me:443 (getaddrinfo: Temporary failure in name resolution)

I've wrote and ran a test to get more insight in the problem. Here is the pseudo code for the test:

loop do
connection = Figo::Connection.new(...)
connection.credential_login(...) #Doesn't matter if the credentials are valid, this is just to send a query
end

On my machine, the loop breaks because of the TCP connection error after exactly 241 iterations.

After looking a the source code for Figo::Connection, I noticed that the HTTP connection was never shutdown. So I extended Figo::Connection like so:

class FigoConnection < Figo::Connection
  def done
    @https.shutdown
  end
end

and modified the test to call done after each query:

loop do
connection = FigoConnection.new(...)
connection.credential_login(...) 
connection.done
end

and now the loop keeps on going after 241 iterations.
The same issue exists in Figo::Session (I haven't tested it but the HTTP connection is managed the same way)

For now, I'm going to extend Figo::Connection and Figo::Session to handle the termination of HTTP connections in my application code.

It would be extremely nice if the ruby-figo gem would manage the connection itself, so this would be transparent to the application code.

Best regards.

I'm running into the same problem at the momment.

Is a fix for this planned?

In the meantime: @kremio did you fo anything besides creating the mentioned done method to Connection and Session or did you do further changes to the project?
