Merge Kakao: Add global status variables which tell you the progress of inplace alter table and row log buffer usage

Details

    Description

      • (x 100%, it's 4-digit. 10000 means 100.00%)
      • Innodb_onlineddl_rowlog_rows
        Shows how many rows are stored in row log buffer.
      • Innodb_onlineddl_rowlog_pct_used
        Shows row log buffer usage in percent ( *100%, it's 4-digit. 10000 means 100.00% ).
      • Innodb_onlineddl_pct_progress
        Shows the progress of inplace alter table. It might be not so accurate becuase inplace alter is highly depend on disk and buffer pool status.
        But still it is useful and better than nothing.
      • Add some log for inplace alter table
      • XtraDB/InnoDB will print some message before and after doing some task.

            In final merge I will not use sql_print_warning(); because that will produce several unnecessary test failures : Found warnings/errors in server log file! in mtr testing. Instead of sql_print_warning() we use sql_print_information()
