Use atomic memory access for purge_sys

    XMLWordPrintable

Details

    Description

      This refactoring is motivated by MDEV-13987 and MDEV-11802.

      The variables purge_sys.state and purge_sys.running are sometimes being read without proper protection, and sometimes read while unnecessarily holding purge_sys.latch exclusively. It is cleaner to use a combination of purge_sys.latch and atomic memory access for writes, so that reads can use either protection.
