2 DIM version 16.14 Release Notes
3
4Notes 1 and 2 for Unix Users only
5NOTE 1: In order to "make" DIM two environment variables should be set:
6 OS = one of {HP-UX, AIX, OSF1, Solaris, SunOS, LynxOS, Linux}
7 DIMDIR = the path name of DIM's top level directory
8 The user should then go to DIM's top level directory and do:
9 > source .setup
10 > gmake all
11 Or, if there is no support for C++ on the machine:
12 > gmake CPP=no all
13
14NOTE 2: The Name Server (Dns), DID, servers and clients (if running in
15 background) should be started whith the output redirected to a
16 logfile ex:
17 Dns </dev/null >& dns.log &
18
19NOTE 3: The Version Number service provided by servers is now set to 1614.

22Changes for version 16.14:
23 - Now by default All DIM processes are ready to accept up to 8192 connections, both
24 in Linux and Windows. Although in Linux for this to be effective the machine system
25 limits must allow more than 1024 descriptors/open files per process.
26 - Fixed a little memory leak in tokenstring.cxx
27 - And a little compilation bug for some platforms in tcpip.c

31Changes for version 16.13:
32 - If DIM_HOST_NODE is defined when starting up a server, a DIM client will now try
33 two network interfaces in order to talk to that server and only give up if they both
34 fail. First it will try the ip name or ip address specified by the server using
35 DIM_HOST_NODE, if that fails it will try the ip address of the default interface
36 retrieved by the server using gethostname (and gethostbyname).
37 The changes basically affect the case in which the DIM_HOST_NODE given to the servers
38 is specified as IP address instad of an IP name. Otherwise this mechanism was already
39 working.

423/05/2007
43Changes for version 16.12:
44 - The Java version did not exit properly when main() terminated - fixed.
45
46
4725/04/2007
48Changes for version 16.11:
49 - On Linux the timeout to detect a lost connections (unplugged ethernet cable
50 or machine reboot) was too long, around 15 minutes - Fixed.
51 On Linux the KEEPALIVE feature is now used instead of a regular socket write,
52 all other platforms should work as before.
53
54
5521/02/2007
56Changes for version 16.10:
57 - Found a bug in dis_stop_serving: one socket connection was not closed - fixed.
58 - Implemented a new environment variable for the DNS: DIM_DNS_ACCEPTED_NODES
59 Can receive a list on nodes or domains separated by commas.
60 If the DNS receives a connection from a node not in this list, it will
61 reject it and kill the server or client requesting it.
62 - Fixed some C++ warnings.
63
64
6519/01/2007
66Changes for version 16.9:
67 - The modifications done in version 16.8 have introduced a bug:
68 - DIM servers would not behave properly (exit) when receiving a kill command
69 from the DNS (for duplicated services, not allowed host names or manual "kill")
70 This is now fixed.
71
72
7330/10/2006
74Changes for version 16.8:
75 - Modified dis_stop_serving() and DimServer::stop() to completely stop DIM:
76 - Stop also the DIM threads.
77 - Release all allocated memory
78 - Allow a different port number when re-starting.
79
80
8111/07/2006
82Changes for version 16.7:
83 - Prepared for increasing the number of open connections per process
84 (On Linux still requires changing some parameters and recompiling the Dns)
85 - Fixed one error and several warnings for gcc 4.
86
87
8811/05/2006
89Changes for version 16.6:
90 - Sometimes a server or client would crash while exiting if the DNS was not running.
91 Fixed.
92 - Fixed the reporting of some ERROR messages on Windows (used to report error "0")
93 - Allowed dim_send_command to receive instead of -dns <node_name>
94 -dns <node_name>[:<port_number>]
95
96
9701/05/2006
98Changes for version 16.5:
99 - Big Spring Cleanup. Removed most warnings. Can now be compiled on
100 Windows with Warning Level 3 and on Linux with -Wall
101 (still not working for -ansi -pedantic...)
102 - When trying to access a server in a different network (i.e. not reacheable)
103 a client (for example DID) would take very very long to timeout - fixed.
104 - Added two new sets of functions that allow setting the DIM_DNS_NODE separately
105 for a server and a client in the same process:
106 - int dis_set_dns_node(char *node)
107 - int dis_get_dns_node(char *node)
108 - int dis_set_dns_port(int port)
109 - int dis_get_dns_port()
110
111 - int dic_set_dns_node(char *node)
112 - int dic_get_dns_node(char *node)
113 - int dic_set_dns_port(int port)
114 - int dic_get_dns_port()
115 These routines should be used instead of the equivalent ones starting with "dim_"
116 since these set the same DIM_DNS_NODE/port for both Server and client parts of a
117 process.
118 - Adapted the C++ equivalents (DimClient::setDnsNode, etc. and DimServer::setDnsNode,
119 etc.) to use the new routines, so they are now independent.
120 Adapted also the Java equivalents.
121 - Fixed DimBridge to use the new routines.
122 - Fixed a bug in DID that made it crash sometimes at startup (and also when the DNS
123 restarted)!
124 - Found some very interesting features of DIM:
125 - In a node with two ethernet interfaces (so connected to two networks):
126 - The DNS will answer to servers and client on both networks, only its server
127 part - DIS_DNS (the one that answers to DID and DimBrowser requests) would
128 in principle answer only to one of the networks (in principle the default
129 interface* but can be changed by setting the environment variable "DIM_HOST_NODE").
130 - But, in fact, if the DNS or any server is started with the environment variable
131 DIM_HOST_NODE set to the interface that is not the default* one. Than both the
132 DNS (including the server part) and the DIM servers will be accessible from both
133 networks. For example DID will work fine on both networks.
134 * The command "hostname" will return the name of the default network interface.
135
136 Note: As a result of inserting new functions the DIM shared library entry points have
137 changed, so all DIM Servers/Clients should be relinked (in particular in Linux).
138
139
14020/04/2006
141Changes for version 16.4:
142 - Optimized the DNS for providing the list or running servers dynamically
143 by subscribing to the service "DIS_DNS/SERVER_LIST"
144
145
14607/04/2006
147Changes for version 16.3:
148 - Upgraded to work on LynxOS Version 4.
149 - Updated makefile for INTEL platform
150 - Updated some ifdefs based on the existence of __Lynx__
151
152
15310/03/2006
154Changes for version 16.2:
155 - Increased the listen queue. To avoid "Connection Refused" messages from servers
156 or from the DNS.
157
158
15928/02/2006
160Changes for version 16.1:
161 - Fixed the NO_THREADS option for LINUX, it had stopped working.
162 - DimInfo::getData() could return an invalid pointer if called before connecting
163 to the server (or discovering the server did not exist). Fixed
164 (it now returns 0 in this case).
165
166
16709/11/2005
168Changes for version 16.0:
169 - Consolidated the new timer handling mechanism, should be much more precise.
170 - Fixed the RPC handling. Used to be based on timming assumptions.
171 Now uses a safe protocol to make sure the server is connected before sending
172 an RPC request.
173 - Included in the distribution some performance measurements and a benchmark
174 server and client. Sources in src/benchmark executables in /bin for windows
175 and /linux for linux.
176 Usage:
177 benchServer <message_size_in_bytes> <number_of_services>
178 benchClient
179 benchClient will run for a while and print the measurement results.
