# Test that old binlog formats can be read. # Some previous versions of MySQL use their own binlog format, # especially in row-based replication. This test uses saved binlogs # from those old versions to test that we can replicate from old # versions to the present version. # Replicating from old versions to new versions is necessary in an # online upgrade scenario, where the . # The previous versions we currently test are: # - version 5.1.17 and earlier trees # - mysql-5.1-wl2325-xxx trees (AKA alcatel trees) # - mysql-5.1-telco-6.1 trees (AKA ndb trees) # For completeness, we also test mysql-5.1-new_rpl, which is supposed # to be the "correct" version. # All binlogs were generated with the same commands (listed at the end # of this test for reference). The binlogs contain the following # events: Table_map, Write_rows, Update_rows, Delete_rows Query, Xid, # User_var, Int_var, Rand, Begin_load, Append_file, Execute_load. # Related bugs: BUG#27779, BUG#31581, BUG#31582, BUG#31583, BUG#32407 source include/not_embedded.inc; --echo ==== Read binlog with v2 row events ==== # Read binlog. --exec $MYSQL_BINLOG --local-load=$MYSQLTEST_VARDIR/tmp/ suite/binlog/std_data/ver_trunk_row_v2.001 | $MYSQL --local-infile=1 # Show result.
