[reSIProcate] bug of ServerSubscription

["Noiile" <noiile@xxxxxxxxxxx>]

<%--AID_SENDTO_BEGIN--%>resiprocate-devel<%--AID_SENDTO_END--%>, Hello

 

When client send two unsubscribes(expires=0) with different Cseq, it will make my program crash.

Because it will make DUM delete ServerSubscription's Dialog object twice. 

 

When ServerSubscription receives a unsubscribe ,it will delete itself, and post a message(DestroyUsage) to delete its Dialog object.

But Dum receives the second unsubscirbe, which call-id is the same as previous, and Cseq is larger than it.

Dum will create a new ServerSubscription with previous ServerSubscription's dialog , because of the same dialog ID. (Two ServerSubscription share one Dialog object!!!)

And then the 2nd ServerSubscription process this unsubscribe message, it will delete itself, and post a message(DestroyUsage) to delete it's Dialog object.

Now, there are 2 DestroyUsage messages in DUM's fifo, so DUM will delete this Dialog object twice!!!

 

I have no ideas to fix it :(
