- Update to 26.4.17:
- "Zero-level" certification keys are implemented. Currently there are 3 levels
of resource keys: schema, table, row, yet one common resource used by every
writeset, a node. The key is added by default to every writeset with the default
type WSREP_KEY_SHARED. Now, node-wide operations can be performed with the same
semantics as regular transactions.
- Non-SYNCED nodes are not counted when calculating commit cut - maximum seqno
that is no longer needed in certification index; situations may arise when group
commit cut is applied before all preceding events are committed on a non-SYNCED
node, now drain all monitors to ensure that preceding events are committed.
- Stability of node joining process for gmcast improved when new nodes are
connecting concurrently as nodes previously may arrive at a different conclusion
on which nodes will be blocked, however now, connections are explicitly allowed
from all nodes which may be accepted as members in the next view.
- Stability of node joining process for EVS improved by dropping EVS join
messages without own identified in joining state, to avoid starting membership
protocol before at least one of the existing nodes has seen at least one join
message from a joiner.
- Improve "Failed to report last committed" warning to make it more accurate and
user-friendly.
- Update to 26.4.16:
- Removed out-of-order certification for BF aborted transactions.
- Better error handling when the socket is closed, also cleaned up excessive
debug logging.
- Update to 26.4.15:
- an assertion is relaxed when Galera is configured with commit order disabled
- in certificate index preload, an assertion in handle_ist_trx_preload() fails
if the first handled IST preload write set has failed certification, and
incrementing the index position caused the certificate index to end up with the
wrong position; now fixed by appending dummy writeset sequence numbers into
