We considered the resync process is finished if a full resync request is ended receiving the "resync-finish" message. But in the case of "shards" each node declared with a "shard" has only a partial view of the table. And the resync process is ended whereas the original peer tables content contains only a "shard" of the full content. This patch allow to retrieve the entire tables requesting a resync from all different "shards". To do so we don't commit the end of a resync process receiving a "resync-finish" if the node is part of "shard", we only flag this peer and all peers using the same shard as "notup2date" as if we received a "resync-partial" message, and we re-schedule a request of a resync as it is done receiving a "resync-partial" message. Doing this the peers flagged "notup2date" won't be addressed for the next resync request round and the next resync request will be send to a shard not yet requested. Receving a "resync-finish" message we also check if all peers using "shards" are flagged "notup2date". It meens that all peers have been addressed and we can considered the resync process is now finished. Note also that the "resync request" scheduler already handle a timeout and if we are not able to retrieve a full resync after a delay. The resync process is ended. This patch should be backported in all versions handling "shard" on peer lines.
