r13339 r13995 1 1 2 DIM version 19.3 1Release Notes2 DIM version 19.35 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 1931. 19 NOTE 3: The Version Number service provided by servers is now set to 1935. 20 21 24/05/2012 22 Changes for version 19.35: 23 - Fixed the DimInfo() default constructor, now if the default constructor is called, it doesn't cause the 24 destructor to crash anymore. 25 - Made available to DimInfo, DimStampedInfo, DimUpdatedInfo and DimCurrentInfo the method: 26 - void subscribe(char *name, void *nolink, int nolinksize, int time, DimInfoHandler *handler) 27 Like this the default constructor can be called and then this method called later to subscribe 28 whenever needed. 29 - The behaviour of a giving a null pointer and size 0 as "no link" parameters was not completely 30 defined. The user could get back either a null pointer or an "invalid" pointer in the callbacks. 31 This is now well-defined: 32 - If null pointer and size 0 is used at subscribe, the user will get null pointer and size 0 in the callback. 33 - If a negative size is passed at subscribe the callback is not called at all. 34 35 36 03/05/2012 37 Changes for version 19.34: 38 - Changed back to dna_write_nowait() the message that the server sends to the client when removing 39 a service. This was causing clients not to reconnect ever again when the server removed services. 40 (because the client would get the info much before the DNS, so it would keep trying to reconnect 41 and failing even though the service or even the server didn't exist anymore, without asking the DNS) 42 - Changed the client in order to avoid the behaviour above, i.e. if sending the service request fails it 43 asks the DNS again. 44 45 46 23/04/2012 47 Changes for version 19.33: 48 - A bug was introduced in v19r30. When trying to retry immediately, a dtq_start_timer(0) 49 was used (like for dna_write). This is not possible because the callback is not protected 50 by a DIM lock. Fixed. (in v19r32) 51 - Small tidy up in dic.c and protecting the move_to_xxx functions. 52 - When a server received an unsubscribe from the last subscribed service of a client it was closing the 53 connection to the client, this is not good because there could be commands being sent. In any case 54 it should be up to the client to close the connection - Fixed. 55 - dim_send_command now accepts a "-i" argument to send integer data (default is string) 56 20 57 21 58 30/03/2012 … … 25 62 as dna_write_nowait as it will mingle the packets. 26 63 - Removed more compiler warnings. 64 27 65 28 66 14/03/2012 -
