Remoting SDK
1

Hi, im using delhpi rio
client → server using synapsetcp → olympia using supertcpchannel

for callback client → server using indyhttp

im using bin message for synapse and indyhttp, one separte message bin for each one

both message bin using aes envelope

from time to time in only two clients (so far) im getting the error
Invalid binary header. Either incompatible or not a binary message.

until the server/olympia crash or just stop…

i cant really trace to any dataset/function/callback in my system, i will send 2 callstack samples here

this one the system was idle, doing nothing

to clarify, when i say two clientes, i mean two separete server application with multiple clients each one, and the error seems to propagate to every client in that server

Hi,

this error is raised if stream isn’t started with RO107 (this is default signature for bin message):

constructor TBinHeader.CreateFromStream(Source: TStream);
begin
  inherited Create();
  Source.ReadBuffer(fHeader, SizeOf(fHeader));
  if not SignatureValid then begin
..
    RaiseInvalidStreamError(err_InvalidHeader, [], Source);  //<<<<<<<<<<<<<<
  end;
end;

Can you create a simple testcase that reproduces this issue, pls?
You can drop it to support@ for keeping privacy

well. no i cant reproduce, thats the main reason im posting

im having from time to time this problem, i cant trace to any action im doing

Hi,

some ideas:

  • try to temporary disable aes envelope and retest.
  • try to grab stream in callback_channel.OnReceiveStream event on client-side. I have suspicion that something is going wrong at decryption of incoming stream. stream should start with RO107 or rorocks signature.

Ty, will try to disabled aes, not sure when i will give a feedback on this, like i said is random today we have 0 erros until now, is not everyday, or even every week
