addrindex patch bitcoin core. it does not show unconfirmed tx
I am not a dev, so I can't tell for sure, but it appears addresses are indexed as they enter the blockchain. 


  I'm sure that unconfirmed txes are showed normally before.


How do you know? I mean, maybe you used this on a server where the state was different, and compared against a server which hadn't received the block by that time?
