Optimize DBUG_PRINT and introduce DBUG_LOG

    XMLWordPrintable

Details

    Description

      MariaDB Server is unnecessarily evaluating the arguments of DBUG_PRINT() macros when the label is not defined.

      The macro DBUG_LOG() for C++ operator<< output which was added for InnoDB diagnostics in MySQL 5.7 is missing from MariaDB. Unlike the MySQL 5.7 implementation, MariaDB will avoid allocating and initializing the output string when the label is not defined.
