[Live-devel] is it a bug?

[Zhixue Zhang]

Dear Ross Finlayson,
In my rtspclient, my destruction function is as follow:
if( m_pMediaSession != NULL  )
	{
	
	MediaSubsessionIterator iter(*m_pMediaSession);
	MediaSubsession* subsession;
	while ((subsession = iter.next()) != NULL) 
	{
		m_pRTSPClient->teardownMediaSubsession(*subsession);
	}
	
	m_pRTSPClient->teardownMediaSession(*m_pMediaSession);
	}
	
	Medium::close(m_pSink);
	Medium::close(m_pMediaSession);
	Medium::close(m_pRTSPClient);
	m_pEnv->reclaim();
	
	delete m_pScheduler;
If rttsp server has died,  in
RTSPClient::teardownMediaSubsession(MediaSubsession& subsession)
getResponse("TEARDOWN", bytesRead, responseCode, firstLine,
nextLineStart)) can not return. It will wait indefinitely, because in
RTSPClient::getResponse1there is not timeout in readSocket(envir(),
fInputSocketNum, &firstByte, 1, fromAddress).
Even if RTSPClient::getresponse() return, "delete[]
(char*)subsession.sessionId" and   " subsession.sessionId = NULL" cannt
be executed for "break".

Maybe I am wrong somewhere, thanks for you advice.

I'm not sure.  If the server dies during the session, then client's 
"sendRequest()" call for the RTSP "TEARDOWN" command will probably 
fail, and then "teardownMediaSubsession()" will just return 
False.  Most clients, however, will probably just ignore that result, 
and continue cleaning up as usual.
