ParseException when message is received in multiple packets #111

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago 
What steps will reproduce the problem?
1. No known steps to reproduce it. It happens when one server message is 
received as multiple TCP packets and there are multiple PipelineMsgParser 
reading the same pipeline.

What is the expected output? What do you see instead?
Each message, even in multiple buffer, should only be processed by one 
PipelineMsgParser.
However, when there were multiple PipelineMsgParser,
One got the first part of the message and the other got the second part which 
caused the ParseException.
Other messages from server after would fail because the starting of the message 
could not be located correctly.

What version of the product are you using? On what operating system?
2.5.2 on Android 4.0.4

Please provide any additional information below.

Here are the log I got (organized for easier to read, not exactly in time 
order).
The first message buffer received starting as "INVITE..."
The second message buffer received starting with "ccept-types:*/*"

**** First part of the message received ****

I believe is due to multiple TCPMessageChannel objects each have its own 
PipelinedMsgParser but they are reading from the same socket.

You might not see this exception as the logging of the parser is disabled by 
default.  You will only notice REGISTER timeout because it will fail to locate 
the head of REGISTER response and eventually cause timeout.

Here is what I found one situation this can happen.

The TCPMessageChannel objects are stored in a table and each one has a key.
One part of the key is the hostname or IP.
When it has to send a SIP message, it generates a key from the SIP message. If 
the message has a route header, it uses the route value to generate the key. 
Otherwise, it uses the request uri.

In my case, TCPMessageChannel is first created with route header and the key 
contains IP of the server.

When there is an error occurred, ImsServiceSession.terminateSession() is 
called. It sends a SIP BYE. However, the SIP BYE uses request-uri to generate 
they key which is a hostname. As a result, even though the hostname and IP are 
of the same server, it doesn't find a match from the MessageChannel table. A 
new TCPMessageChannel is created.

The existing TCPMessageChannel and new TCPMessageChannel are then reading from 
the same socket which will eventually cause the issue each channel read a part 
of a long SIP message.

Try to take a look at the following issue from JSIP project:
