[Spread-users] An unintentional bug in spread daemon 4 releasecandidate for windows

[Jacob Green]

Thanks Danish.  Bug has been fixed, and all win32 project files link with
wsock32.lib rather then Ws2_32.lib.

releasecandidate for windows

 

Hi all

I run spread  daemon with following configuration

Spread_Segment 234.5.6.7:5120 {

danish

jaywks

}

danish and jaywks are 2 computer names on our LAN.

i always got error:

DL_init_channel: problem in setsockopt to multicast address -368769529

Then i open spread code and debug it. What i saw the following call always
fail in Data_link.c file in DL_init_channel function.

if (setsockopt(chan, IPPROTO_IP, IP_ADD_MEMBERSHIP, (void *)&mreq, 

sizeof(mreq)) < 0) 

{

Alarm( EXIT, "DL_init_channel: problem in setsockopt to multicast address
%d\n", mcast_address );

}

Then i was trying to see code carefully and was making some alteration but i
did not find any solution that would worked. As socket option always got
failed so i guessed it is some problem with membership option. So i made
another program( a very simple one ) to check this API and what i saw it too
always failed. Then i searched it and found it is a problem in winsock
library inclusion from the link http://support.microsoft.com/kb/q257460/.

So i changed the import library file according to this article and it
worked.

Suggestion:

Review all other spread projects source code for socket options and their
conflicts on winsock libraries and correct them if required according to
given link.

Best Regards

Danish Ahmed
