- Changed replica_parallel_workers in configuration for 8.0 and 8.4 to o, because wiat_for_replicas is buggy for multi-threaded slaves (cherry picked from commit d9b0219d9e)
- Minor tests diagnostic and cleanup
- Implemented functions get_replica_name and get_source_name in lib/MasterSlave.pm I did not implement similar functions in other places, because they set other variables as well, not only replica_name or source_name.
- Added test for replica lag check for pt-archiver
- Re-added deprecated slave- options
- Added tests for deprecation warnings and for legacy options for pt-archiver
- Removed practically not supported options --replica-user and --replica-password from pt-archiver, pt-kill, pt-query-digest
- Added legacy source/replica options (master/slave) variants and tests for pt-heartbeat, pt-online-schema-change, pt-replica-find, pt-replica-restart, pt-table-checksum, pt-table-sync
- Updated modules after lib/MasterSlave.pm change
