[OpenSIPStack] FW: Memory Leak in Proxy and Full Mode

[Gustavo C. <cur...@ho...>]

Hi Joegen:
 
The memory leak is hard to find. I send the 200 OK repeatedly but the memory leak doesn't appear if i'm debugging with Microsot Visual 2005, but the leak appears if i'm running the OpenSBC like a service.
 
If I comment:
 
 
void SIPStack::EnqueueTransportWriteEvent(
const SIPMessage & message,
SIPTransportEvent::Type eventType
)
{
      if( m_IsTerminating )
          return;
 
      /*SIPMessage * msg = new SIPMessage(message);

      msg->SetInternalHeader( "TRN-ID", msg->GetTransactionId().AsString());
      m_TransportManager->EnqueueEvent( new SIPTransportEvent( msg, eventType ) );*/
}
 
  there is not leak. But if I modify the code like this:
 
 
void SIPStack::EnqueueTransportWriteEvent(
const SIPMessage & message,
SIPTransportEvent::Type eventType
)
{
      if( m_IsTerminating )
          return;
 
      SIPMessage * msg = new SIPMessage(message);

      /*msg->SetInternalHeader( "TRN-ID", msg->GetTransactionId().AsString());
      m_TransportManager->EnqueueEvent( new SIPTransportEvent( msg, eventType ) );*/
      delete msg;
}
 
the leak shows up. I don't understand why this happens if I'm deleting the msg.
What i said in the last mail about CSeq is  not seem to be the reason. 
Any idea? Thanks for your help.
Gustavo

Hi Joegen: I found that the memory leak is when you create a SIPMessage from other SIPMessage or from a OString and then you delete de message. In the case of the 200 Ok the message is created in:  ProxySessionManager::OnOrphanedMessage()SIPUserAgent::TransportWrite()SIPStack::EnqueueTransportWriteEvent(){SIPMessage * msg = new SIPMessage(message);  The memory leak is because the CSeq header. If i comment :  SIPMessage::SIPMessage(const SIPMessage & msg)SIPMessage & SIPMessage::operator=(const SIPMessage & msg)void SIPMessage::AssignContents(SIPMessage & msg){  /*if( m_CSeq != NULL )    msg.m_CSeq = static_cast<CSeq*>(m_CSeq->Clone());*/} There is no more memory leak.  I try to replace: SIPMessage * msg = new SIPMessage(message); ----> SIPMessage * msg = new SIPMessage(message.AsString()); but the memory leak still exist unless i comment: void SIPMessage::Finalize(){   /*if( m_CSeq == NULL )  {       m_CSeq = new CSeq( h );   }*/} That's what i found so far.

When i send a 200 Ok for example in B2B mode there is no memory leak, but when i send a 200 ok in Proxy or Full mode, some memory is taken and never released. I attach the logs. The OpenSBC (192.168.0.202:5070) is running under Windows.> > > > Thanks for your help> > > > Gustavo> > _________________________________________________________________> > Ingresá ya a MSN Deportes y enterate de las últimas novedades del mundo deportivo.> > http://msn.foxsports.com/fslasc/> > ------------------------------------------------------------------------> >> > -------------------------------------------------------------------------> > This SF.net email is sponsored by: Microsoft> > Defy all challenges.
