SIGHUP during rsync SST causes SST to fail

    XMLWordPrintable

Details

    Description

      This is similar to MDEV-14282, but it seems slightly different.

      If a SIGHUP is received during an rsync SST, then the SST will fail:

      Jenkins and/or Ansible seems to send SIGHUP signals for some reason, so that's when this issue occurs.
