In MariaDB, we have a confusing problem where: * The transaction_isolation option can be set in a configuration file, but it cannot be set dynamically. * The tx_isolation system variable can be set dynamically, but it cannot be set in a configuration file. Therefore, we have two different names for the same thing in different contexts. This is needlessly confusing, and it complicates the documentation. The same thing applys for transaction_read_only. MySQL 5.7 solved this problem by making them into system variables. https://dev.mysql.com/doc/relnotes/mysql/5.7/en/news-5-7-20.html This commit takes a similar approach by adding new system variables and marking the original ones as deprecated. This commit also resolves some legacy problems related to SET STATEMENT and transaction_isolation.
