Michal Linhard reopened ISPN-2574:
----------------------------------



Adrian please check out my test case: https://github.com/mlinhard/infinispan/commit/8681c35c95aeba128ae28a1c2aba9609b2b9e2b8

it doesn't work for current master.

the test scenario is a more simple one:
config: distribution, num owners 2

1. create cluster {A,B}, fill 1000 entries
2. join C
3. when B is about to send StateResponseCommand to C, fail B, never send the command
4. C should restart the state transfer and ask the same segments from A
5. cluster {A, C} will form with all segments properly backed up on both A and C

Beta4 didn't restart the state transfer which meant some entries weren't properly transfered to C
Beta6 did this alright
current master again fails to restart the state transfer from A

> Imagine this situation in distributed cache with 3 owners:
> 1) The segment X is owned by nodes A, B, C
> 2) Node B fails -> CH_UPDATE and then REBALANCE_START are broadcasted
> 3) Node D starts transfer of segment X from C
> 4) Node C fails -> another CH_UPDATE is broadcasted
> 5) D handes the CH_UPDATE and removes the transfer of segment X from C, but does not start another transfer from A
> The {{addedSegments}} does not contain the restarted transfer, because all transfers from write consistent hash are removed from it in the beginning - the segment is considered received here although the transfer is still in progress.
