DIM version 16.07 Release Notes

Notes 1 and 2 for Unix Users only
NOTE 1: In order to "make" DIM two environment variables should be set:
	OS = one of {HP-UX, AIX, OSF1, Solaris, SunOS, LynxOS, Linux}
	DIMDIR = the path name of DIM's top level directory
	The user should then go to DIM's top level directory and do:
	> source .setup
	> gmake all
	Or, if there is no support for C++ on the machine:
	> gmake CPP=no all

NOTE 2: The Name Server (Dns), DID, servers and clients (if running in 
	background) should be started whith the output redirected to a 
	logfile ex:
		Dns </dev/null >& dns.log &

NOTE 3: The Version Number service provided by servers is now set to 1607.

Changes for version 16.7:
    - Prepared for increasing the number of open connections per process
      (On Linux still requires changing some parameters and recompiling the Dns)
    - Fixed one error and several warnings for gcc 4.


11/05/2006
Changes for version 16.6:
    - Sometimes a server or client would crash while exiting if the DNS was not running.
      Fixed.
    - Fixed the reporting of some ERROR messages on Windows (used to report error "0")
    - Allowed dim_send_command to receive instead of -dns <node_name>
	-dns <node_name>[:<port_number>]


01/05/2006
Changes for version 16.5:
    - Big Spring Cleanup. Removed most warnings. Can now be compiled on
      Windows with Warning Level 3 and on Linux with -Wall
      (still not working for -ansi -pedantic...)
    - When trying to access a server in a different network (i.e. not reacheable)
      a client (for example DID) would take very very long to timeout - fixed.
    - Added two new sets of functions that allow setting the DIM_DNS_NODE separately
      for a server and a client in the same process:
	- int dis_set_dns_node(char *node)
	- int dis_get_dns_node(char *node)
	- int dis_set_dns_port(int port)
	- int dis_get_dns_port()

	- int dic_set_dns_node(char *node)
	- int dic_get_dns_node(char *node)
	- int dic_set_dns_port(int port)
	- int dic_get_dns_port()
      These routines should be used instead of the equivalent ones starting with "dim_"
      since these set the same DIM_DNS_NODE/port for both Server and client parts of a 
      process.
    - Adapted the C++ equivalents (DimClient::setDnsNode, etc. and DimServer::setDnsNode, 
      etc.) to use the new routines, so they are now independent.
      Adapted also the Java equivalents.
    - Fixed DimBridge to use the new routines.
    - Fixed a bug in DID that made it crash sometimes at startup (and also when the DNS 
      restarted)!
    - Found some very interesting features of DIM:
        - In a node with two ethernet interfaces (so connected to two networks):
	    - The DNS will answer to servers and client on both networks, only its server
              part - DIS_DNS (the one that answers to DID and DimBrowser requests) would
              in principle answer only to one of the networks (in principle the default
              interface* but can be changed by setting the environment variable "DIM_HOST_NODE").    
	    - But, in fact, if the DNS or any server is started with the environment variable 
              DIM_HOST_NODE set to the interface that is not the default* one. Than both the 
              DNS (including the server part) and the DIM servers will be accessible from both 
              networks. For example DID will work fine on both networks.
            * The command "hostname" will return the name of the default network interface.   

    Note: As a result of inserting new functions the DIM shared library entry points have
          changed, so all DIM Servers/Clients should be relinked (in particular in Linux).


20/04/2006
Changes for version 16.4:
    - Optimized the DNS for providing the list or running servers dynamically
      by subscribing to the service "DIS_DNS/SERVER_LIST"


07/04/2006
Changes for version 16.3:
    - Upgraded to work on LynxOS Version 4. 
      - Updated makefile for INTEL platform
      - Updated some ifdefs based on the existence of __Lynx__


10/03/2006
Changes for version 16.2:
    - Increased the listen queue. To avoid "Connection Refused" messages from servers
      or from the DNS.


28/02/2006
Changes for version 16.1:
    - Fixed the NO_THREADS option for LINUX, it had stopped working.
    - DimInfo::getData() could return an invalid pointer if called before connecting
      to the server (or discovering the server did not exist). Fixed 
      (it now returns 0 in this case).


09/11/2005
Changes for version 16.0:
    - Consolidated the new timer handling mechanism, should be much more precise.
    - Fixed the RPC handling. Used to be based on timming assumptions.
      Now uses a safe protocol to make sure the server is connected before sending 
      an RPC request.
    - Included in the distribution some performance measurements and a benchmark 
      server and client. Sources in src/benchmark executables in /bin for windows
      and /linux for linux.
      Usage:
	benchServer <message_size_in_bytes> <number_of_services>
	benchClient
      benchClient will run for a while and print the measurement results.
