Hello again folks,
I managed to "fix" the bug I told you guys about. Aparently it is endeed
an ICS related problem or AMD's fault, can't be concise on that. Here's an
overview of the problem with the solution in sample codes:
Problem: The server did not received the packet from the client, only
the first one. The packets in question were being sent from inside a for
loop (small one, about 50 iterations). Here is a sample code of the "faulty"
version of the code (Delphi 6):
for I := 0 to Count-1 do
begin
// This line being the assembly of the buffer,
// it is a very clean code and is a very fast function and very few
data.
// Buffer size estimations are about 20- bytes.
BuildMessage(aString, aBuffer);
// sends rapid-fire buffers to the server
Socket.Send(@aBuffer[0], Length(arBuffer));
end;
Solution: Using the cumulative send function provided with ICS the
problem is strangely resolved and the server receves ok the buffers (in this
case, the single buffer made of the small buffers). Here is the sample code:
for I := 0 to Count-1 do
begin
// Same buffer assemblage
BuildMessage(aString, aBuffer);
// Only sends the packet when the processing is finished (last
iteration)
if I = (Count - 1) then
Socket.Send(@aBuffer[0], Length(aBuffer))
else
Socket.PutDataInSendBuffer(@aBuffer[0], Length(aBuffer));
end;
I hope I could be of any help and I'm pretty sure this can be reproduced
(using the sample codes above) in any client/server model being the client
an AMD 64-Bit processor (can't say much about Intel 64-Bit processors
because we could not test it out). Anyways, thank you very much for all your
responses!
Best regards,
Marcelo Grossi
