r12757 r13135 1 1 2 DIM version 19. 27Release Notes2 DIM version 19.30 Release Notes 3 3 4 4 Notes 1 and 2 for Unix Users only … … 17 17 Dns </dev/null >& dns.log & 18 18 19 NOTE 3: The Version Number service provided by servers is now set to 1927. 19 NOTE 3: The Version Number service provided by servers is now set to 1930. 20 21 14/03/2012 22 Changes for version 19.30: 23 - Sometimes when trying to open a connection to a server the client could backoff for too 24 long (10 seconds), now it will retry immediately and then at increasing intervals. 25 - dim_stop() would sometimes not properly stop all threads if a new connection was received 26 in the mean time. 27 - The DimServerDns destructor could crash, fixed. 28 - Removed some compiler warnings about variables set but not used. 29 - Two new functions available: 30 - dim_set_listen_backlog(int size) 31 - int dim_get_listen_backlog() 32 - The DNS will set the listen_backlog to 1024 at startup, but the OS will truncate it to 33 a maximum limit (available in /proc/sys/net/core/somaxconn, linux default=128), 34 while for servers the constant SOMAXCONN is used. 35 36 37 06/02/2012 38 Changes for version 19.28: 39 - Added more log messages when a "Write Timeout" occurs to know where it originated. 40 - A server could sometimes not release the connection in case of a "Write Timeout", and 41 then keep on timing out for each message on this connection - fixed. 42 20 43 21 44 19/01/2012 -
