[reSIProcate] bug of ServerSubscription

[Scott Godin]

Are you using the latest code from SVN? - I think a recent fix to
DialogSet.cxx line 363 will fix this problem.

resiprocate-devel, 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 :(
