    • Status: Closed (View Workflow)
    • Major
    • Resolution: Fixed
    • 10.0(EOL), 10.1(EOL)
    • 10.0.20, 10.1.5
    • Replication
    • None

    Description

      Note: Unfortunately I can't check if the problem is reproducible on 10.0, because the binlog uses syntax introduced in 10.1 with table encryption.

      Stack trace is from 10.1 commit 8c54182e + patch http://lists.askmonty.org/pipermail/commits/2015-May/007819.html ; the binlog was produced on 10.1 commit 2f25c653 + the same patch + patch for MDEV-8045.

      To reproduce:

      • start master with all default options + --log-bin=mysql-bin --server-id=1, with the attached mysql-bin.* files in the datadir;
      • start slave with all default options + --server-id=2 --plugin-load-add=file_key_management.so --file_key_management_filename=<your basedir>/mysql-test/std_data/keys.txt --slave_parallel_threads=8;
      • set up replication (either old-fashioned or GTID, doesn't matter);
      • wait.
