"""
|
|
The test starts two single-node clusters (with different group0_ids). Node B (the
|
|
node from the second cluster) is restarted with seeds containing node A (the node
|
|
from the first cluster), and thus it tries to gossip node A. The test checks that
|
|
node A rejects gossip_digest_syn.
|
|
|
|
Note: this test relies on the fact that the only node in a single-node cluster
|
|
always gossips with its seeds. This can be considered a bug, although a mild one.
|
|
If we ever fix it, this test can be rewritten by starting a two-node cluster and
|
|
recreating group0 on one of the nodes via the recovery procedure.
