The tool is named mariadb-migrate-config-file. The main purpose of the tool is to change MySQL option files to work both for MySQL and MariaDB. There are options to do the changes in the options file inline, or at-end-of-file. One can also remove or comment unknown options. The list of supported options is generated compile time from mariadbd --help. All server options, including compiled plugins, are supported. The bulk of the code comes from Väinö. Monty has updated it with a lot of extra options. Wlad helped with cmake integration Other things: - Fixed a memory leak in sql_plugin.cc - plugin-load will now in case of errors try to load all given plugins before aborted - If silent-startup is used, plugin-load will not give errors for plugins it cannot load or warnings about plugin marturity level. - my_rm_tree() will now delete symlinks, not the actual file, if MY_NOSYMLINK flag is used. - my_stat() will now give data for symlink if MY_NOSYMLINKS is used. - Added 'number of lines' option to mysqltest --cat_file @Authors: Väinö Mäkelä <vaino.makela@iki.fi>,monty@mariadb.com
