Re: [sipxtapi-dev] Problems in using SipPimClient (SIPSIMPLE message)

Hello,

please check if calling:

pSipUserAgent->removeMessageObserver(pPimClient->getMessageQueue());

where pSipUserAgent is your SipUserAgent instance and pPimClient is SipPimClient

before you destroy SipPimClient instance helps.

Best Regards,

Andrzej

Hi,

Andrzej, thanks a ton for looking into the matter :).

I added the following checks to line number 1821 in SipUserAgent.cpp:

if ( request

&& (shouldDispatch || delayedDispatchMessage)

&& delayedResponseCode != 404

&& delayedResponseCode != 415

&& delayedResponseCode != 407

&& delayedResponseCode != -1)

{

...

}

Sure, it's a pathetic hack :(, but it seems to avoid the crash. And now I'm able to send/receive messages across freeworlddialup.com and other servers (I still have problems when I try this against Brekeke on a LAN). I guess till a proper solution is found I will have to persist with this only.

Thanks,

Hitesh

Hello,

I see is SipPimClient code, that sendPagerMessage() creates its own message queue which is used for receiving the response. It seems that after receiving some response which triggers completion of sendPagerMessage() and destruction of the message queue, SipUserAgent receives some message which it "thinks" is another response to your MESSAGE. I wonder if this is related somehow to the fact that both the sent and received MESSAGE have the same Call-Id?

Hi,

I'm able to recieve messages but when I try sending one then the application crashes at the following line:

if (!mbShuttingDown)

{

responseQ->send(eventMsg); //<---Crashes here, line 1851, SipUserAgent.cpp

}

Below is the call stack:

sipXtapid.dll!SipUserAgent::dispatch(SipMessage * message=0x01c5ead8, int messageType=0, SIPX_TRANSPORT_DATA * pTransport=0x00000000) Line 1851 + 0x14 C++

sipXtapid.dll!SipClient::run(void * runArg=0x00000000) Line 468 + 0x27 C++

sipXtapid.dll!OsTaskWnt::threadEntry(void * arg=0x01c5e3f8) Line 587 + 0x22 C++

The value of responseQ is shown to be:

- responseQ 0x0359f124 {mGuard={mMutexImp=??? } mEmpty={mSemImp=??? } mFull={mSemImp=??? } ...} OsMsgQShared *

+ OsMsgQBase {DEF_MAX_MSGS=100 DEF_MAX_MSG_LEN=32 MSGQ_PREFIX={TYPE=0x1037c16c "UtlString" ssNull=0x10375710 "" UTLSTRING_NOT_FOUND=4294967295 ...} ...} OsMsgQBase

mOptions CXX0030: Error: _expression_ cannot be evaluated int

mHighCnt CXX0030: Error: _expression_ cannot be evaluated int

I have attached the Ethereal trace and the log file. The code that I'm using is shown below.

Please help.

Thanks,

Hitesh
