This is an automated notification of a change to freeciv cvs,
on Wed Jan 23 00:58:30 PST 2002 = Wed Jan 23 08:58:30 2002 (GMT)
by Raimar Falke <rf13@xxxxxxxxxxxxxxxxxxxxxx>

---- Files affected:

freeciv/server srv_main.c

---- Log message:

Send PACKET_START_TURN for every reconnect. This ensures that there is
a PACKET_START_TURN for every PACKET_GAME_STATE packet which contains
CLIENT_GAME_RUNNING_STATE as its value.

One PACKET_START_TURN is also sent for every new turn
(PACKET_BEFORE_NEW_YEAR or PACKET_NEW_YEAR are indicators for this).

However this change was made 23 Jan. Odd.

During certain time spans (at the new turn or between
PACKET_PROCESSING_STARTED and PACKET_PROCESSING_FINISHED) the client
gets inconsistent data. During these time spans new data doesn't cause
callbacks but is queued. The agents are froozen during these time
spans.
