Embedded server shutdown hangs in InnoDB

    XMLWordPrintable

Details

    Description

      Ever since MDEV-5800 enabled indexed virtual columns for InnoDB, the InnoDB shutdown relied on close_connections() that would set thd->killed for the InnoDB purge threads. Alas, the embedded server shutdown is not invoking close_connections(), and thus InnoDB purge threads fail to initiate shutdown, causing the embedded server to hang.
      This is repeatable at a high probability by running

      ./mtr --repeat=100 --embedded gcol.innodb_virtual_debug_purge
