############################################################################### # mysqldump_restore.test # # Purpose: Tests if mysqldump output can be used to successfully restore # tables and data. # We CREATE a table, mysqldump it to a file, ALTER the original # table's name, recreate the table from the mysqldump file, then # utilize include/diff_tables to compare the original and recreated # tables. # # We use several examples from mysqldump.test here and include # the relevant bug numbers and headers from that test. # # NOTE: This test is not currently complete and offers only basic # cases of mysqldump output being restored. # Also, does NOT work with -X (xml) output! # # Author: pcrews # Created: 2009-05-21 # Last Change: # Change date: ############################################################################### # Embedded server doesn't support external clients --source include/not_embedded.inc --source include/have_log_bin.inc --echo # Set concurrent_insert = 0 to prevent random errors --echo # will reset to original value at the end of the test SET @old_concurrent_insert = @@global.concurrent_insert; SET @@global.concurrent_insert = 0; # Define mysqldumpfile here.
