Problem: Statements that write to tables with auto_increment columns based on the selection from another table, may lead to master and slave going out of sync, as the order in which the rows are retrieved from the table may differ on master and slave. Solution: We mark writing to a table with auto_increment table based on the rows selected from another table as unsafe. This will cause the execution of such statements to throw a warning and forces the statement to be logged in ROW if the logging format is mixed. Changes: 1. All the statements that writes to a table with auto_increment column(s) based on the rows fetched from another table, will now be unsafe. 2. CREATE TABLE with SELECT will now be unsafe. sql/share/errmsg-utf8.txt: Added new warning messages. sql/sql_base.cc: -Created function to check statements that write to tables with auto_increment column and has select. -Marked all the statements that write to a table with auto_increment column based on rows fetched from other table(s) as unsafe. sql/sql_table.cc: mark CREATE TABLE[with auto_increment column] as unsafe.
