2e11a26f41 Fixed bug on candidate selection. I misinterpreted count and n_connections variables. Thus, renamed count as current_connection_count to make it more understandable. 2013-08-13 12:12:19 +03:00

c1c8bf9fc5 Removed unnecessary loop of servers. Now we loop over all the servers, if running server is found and candidate is not set we set that server as candidate. If candidate is set and we find any that have fewer connections than our candidate server. If a server has less connections than the current candidate we mark this as the new candidate to connect to. If a server has the same number of connections currently as the candidate and has had less connections over time than the candidate it will also become the new candidate. This has the effect of spreading the connections over different servers during periods of very low load. 2013-08-13 11:55:34 +03:00

6c106bb9be Removed #if defined(SS_DEBUG) macros around trace log print commands. Trace log is disabled by default but it is meant to be possible to enable it with other than debug build only. 2013-08-09 15:27:02 +03:00
