[Spread-users] small bug and questions

[Lobiv Igor]

Bug:

 

Sp.c

int SP_connect_timeout(

...

      host_address = ( (i1 << 24 ) | (i2 << 16 ) | (i3 << 8) | i4 ); // bug here

 

under win32 on AMD Athlon XP 2800+ it is not work...

If string for connect is 3333 at 128.220.221.1

TCP connection goes to port 3333, IP 1.221.220.128, but it is expected "128.220.221.1"

 

I suggest use instead:

host_address = htonl(( (i1 << 24 ) | (i2 << 16 ) | (i3 << 8) | i4 ));

 

 

Questions:

 

1)       How works message synchronization - i.e. if someone sends message(MSG) to group with two members M1 and M2 is message arrived in the same time to both members or asynchronously?

2)       As I understand a message stays in some queue on spread demon(s) until all spread users in group received it. Is it true? How I can manipulate this queue - measure max load, change size, add "expired time"?

3)       How I can change the "strategy of delivery"? For example I want to implement load sharing in the group with two members M1 and M2. Odd messages process M1, even messages process M2.
