[reSIProcate] Route Set problem with Update in resip 1.1 RC1

Thu Mar 8 12:29:32 CST 2007

Ah - I think I figured out what is updating the CSeq in
creator->getLastRequest - we use a SharedPtr to pass the lastRequest
message from the creator to ClientInviteSession and it get's stored as
mLastSessionModification.  Every re-invite we sent out uses this
sharedptr to create the new request.  This consequently updates the
message retrieved by creator->getLastRequest(). 

I'll look into fixing this.

Thanks ,

Scott

Thanks for trying again Bill - but I must admit - I'm baffled.

1.       Creator->getLastRequest()->header(h_CSeq).sequence() should be
1 when initial invite is sent.

2.       Creator->getLastRequest()->header(h_CSeq).sequence() is changed
to 2 when INVITE with ProxyAuth is sent out

3.       Creator->getLastRequest()->header(h_CSeq).sequence() should not
be modified again (I can't find any where that would modify it).

4.       The 200 response to your re-invite carries a CSeq of 3.  And
since 3 doesn't equal
Creator->getLastRequest()->header(h_CSeq).sequence() -> 2 - then the
routeset should not be updated - when using the following code (in
Dialog::dispatch for responses):

      const SipMessage& response = msg;

      int code = response.header(h_StatusLine).statusCode();

      // If this is a 200 response to the initial request, then store
the routeset (if present)

      BaseCreator* creator = mDialogSet.getCreator();

      if (creator &&
(creator->getLastRequest()->header(h_CSeq).sequence() ==
response.header(h_CSeq).sequence()) && code >=200 && code < 300)

      {

         if (response.exists(h_RecordRoutes))

         {

            mRouteSet = response.header(h_RecordRoutes).reverse();

         }

      }

Any idea's why?  Do you any other local edits that may be causing
creator->getLastRequests sequence number to be incremented (perhaps
modifications to ClientAuthManager)?

Scott, 

I put your code back in and ran the scenario where I send INVITE, INVITE
w/Proxy-Auth and Re-Invite.

Each 200 OK updated mRouteSet
