*** [err]: PSYNC2: total sum of full synchronizations is exactly 4 intests/integration/psync2.tcl
Expected 5 == 4 (context: type eval line 8 cmd {assert {$sum == 4}} proc::test)
Sometime the test got an unexpected full sync since a replica switch to master,
before the new master change propagated the new replid to all replicas,
a replica attempted to sync with it using a wrong replid and triggered a full resync.
Consider this scenario:
1 slaveof 4 full resync
0 slaveof 4 full resync
2 slaveof 0 full resync
3 slaveof 1 full resync
1 slaveof no one, replid changed
3 reconnect 1, did a partial resyn and got the new replid
Before 2 inherits the new replid.
3 slaveof 2
3 try to do a partial resyn with 2.
But their replication ids are inconsistent, so a full resync happens.
:) A special thank you for oran and helping me in this test case.
