Hello,
I am suspcious about:
{* * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * *
*}
{ Triggered when socket is closed. Need to inform server socket to
date }
{ client list and trigger client disconnect
}
procedure TWSocketMTClient.TriggerSessionClosed(ErrCode : Word);
begin
if not FSessionClosedFlag then begin
FSessionClosedFlag := TRUE;
if Assigned(FServer) then begin
try
FServer.TriggerClientDisconnect(Self, ErrCode);
finally
{ Calling Destroy will automatically remove client from list
because }
{ we installed a notification
}
Release;
end;
end;
inherited TriggerSessionClosed(ErrCode);
end;
end;
This is called in the worker thread context and I removed the postmessage
for speed. But I am not sure of Release()--is it ok to be called before
inherited TriggerSessionClosed()?
Left problems:
- lock up
- memory leak
bad enough? ;((
