binlog_xa_trx_split_across_binlog.test
############################################################################### # This test script is to check the behaviour of applying XA transaction from # a binlog dump if the XA transaction split across binary logs. # # Steps to reproduce: # 1) Reset the master and set max_binlog_size to a smaller value 4KB. # 2) Start a XA transaction which is more than max_binlog_size (4KB). # 3) Prepare the XA trx. # (trx content will be written to master-bin.000001 and the binlog # will be rotated because of the size limit). # 4) Commit the XA trx (commit will be written to binlog2). # 5) Save the binlog dump for the reapply purpose. # 6) Cleanup the server and make it ready to apply the binlog dump. # 7) Apply the binlog dump. # 8) Verify that the old data is restorted properly without any issues. # 9) Cleanup. ############################################################################### --source include/have_binlog_format_row.inc --let $MYSQLD_DATADIR= `select @@datadir` --echo # --echo # 1) Reset the master and set max_binlog_size to a smaller value 4KB. --echo # SET @save_max_binlog_size=@@global.max_binlog_size; SET GLOBAL max_binlog_size=4096; RESET MASTER; --echo # --echo # 2) Start a XA transaction which is more than max_binlog_size (4KB). --echo # CREATE TABLE t1(i varchar(4096)); XA START 'xa1'; INSERT INTO t1 VALUES (REPEAT('a', 4096)); XA END 'xa1'; --echo # --echo # 3) Prepare the XA trx. --echo # (trx content will be written to master-bin.000001 and the binlog --echo # will be rotated because of the size limit).
