MDEV-23372: rpl.rpl_skip_replication still fails in buildbot with an extrabb-10.2-sujatha
warning
Problem:
========
[Warning] Aborted connection 18 to db: 'unconnected' user: 'root' host:
'localhost' (Got an error reading communication packets)
[Note] Start binlog_dump to slave_server(2), pos(, 4), using_gtid(0),
gtid('')
[Warning] Aborted connection 17 to db: 'unconnected' user: 'root' host:
'localhost' (A slave with the same server_uuid/server_id as this slave has
co)
[Warning] Master is configured to log replication events with checksum, but
will not send such events to slaves that cannot process theml
Analysis:
=========
Issue is similar MDEV-14203. MDEV-14203 fix addressed network write error
issue now the same needs to be implemented for network read error.
Fix:
===
Upon network read error donot attempt reconnect, proceed to master-slave
handshake. This ensures that master is aware of slave's capability to use
checksums.
