Increase buffer size for query in SHOW ENGINE INNODB STATUS output

    XMLWordPrintable

Details

    Description

      In SHOW ENGINE INNODB STATUS output or in the output of the lock monitor, the query text and other basic information about the session seems to get copied to a buffer that is only 1024 bytes large. See here:

      https://github.com/MariaDB/server/blob/mariadb-10.2.31/storage/innobase/handler/ha_innodb.cc#L2155

      This means that even moderately long queries can be truncated.

      Maybe we should increase the size of this buffer.
