[computer-go] KGS tournament problem

[Edward de Grijs]

Hello,

In relation to the last played KGS tournament:
First of all sorry for those programs that played against a non available 
"firstgo".
Because others can learn from what happened I post my observation here.
I could not attend round 2 to 6, and I saw this logging after round 6:

8-okt-2006 11:32:37 org.igoweb.kgs.client.gtp.GtpClient d
FINEST: Got successful response to command "genmove b": = RESIGN
8-okt-2006 11:32:37 org.igoweb.kgs.client.gtp.GtpClient d
SEVERE: Error from GTP Communications layer, closing down.
org.igoweb.igoweb.client.gtp.ai: Cannot recognize vertex "RESIGN" that came 
from engine.

Because of this, which happened after round two, the communication stopped, 
until
I restarted the communication at the start of round 7.

It seems to me that the server is not case sensitive in relation to the 
"RESIGN" vertex.
The specification of GTP states that the "vertex" answer is non case 
sentitive.
So I even use a "PASS" answer instead of "pass", but this works fine.

So the following questions came to my mind:
1) Should I use "resign" instead of "RESIGN", or is this a bug in the server 
software
   which should be corrected?
2) Why is the communication closing down? If a command is not recognised, 
the following
   round could be continued with a clear_board and such, hereby improving 
the fault
   tolerance of the communication protocol?

Edward
