This leads +# to scenarios on which the slave replicates the statement and it +# will try to load the file from local file system, which in most +# likely it will not exist. +# +# Solution: +# Marking this function as unsafe for statement format, makes the +# statement using it to be logged in row based format. As such, data +# replicated from the master, becomes the content of the loaded file. +# Consequently, the slave receives the necessary data to complete +# the load_file instruction correctly. +# +# IMPLEMENTATION +# +# The test is implemented as follows: +# +# On Master, +# i) write to file the desired content. +# ii) create table and stored procedure with load_file +# iii) stop slave +# iii) execute load_file +# iv) remove file +# +# On Slave, +# v) start slave +# vi) sync it with master so that it gets the updates from binlog (which +# should have bin logged in row format). +# +# If the the binlog format does not change to row, then the assertion +# done in the following step fails. This happens because tables differ +# since the file does not exist anymore, meaning that when slave +# attempts to execute LOAD_FILE statement it inserts NULL on table +# instead of the same contents that the master loaded when it executed +# the procedure (which was executed when file existed). +# +# vii) assert that the contents of master and slave +# table are the same + +--source include/rpl_reset.inc + +connection master; +let $file= $MYSQLTEST_VARDIR/tmp/bug_39701.data; + +--replace_result $MYSQLTEST_VARDIR MYSQLTEST_VARDIR +--eval SELECT repeat('x',20) INTO OUTFILE '$file' + +disable_warnings; +DROP TABLE IF EXISTS t1; +enable_warnings; + +CREATE TABLE t1 (t text); +DELIMITER |; +CREATE PROCEDURE p(file varchar(4096)) + BEGIN + INSERT INTO t1 VALUES (LOAD_FILE(file)); + END| +DELIMITER ;| + +# stop slave before issuing the load_file on master +connection slave; +source include/stop_slave.inc; + +connection master; + +# test: check that logging falls back to rbr. +--replace_result $MYSQLTEST_VARDIR MYSQLTEST_VARDIR +--eval CALL p('$file') + +# test: remove the file from the filesystem and assert that slave still +# gets the loaded file +remove_file $file; + +# now that the file is removed it is safe (regarding what we want to test) +# to start slave +connection slave; +source include/start_slave.inc; + +connection master; +sync_slave_with_master; + +# assertion: assert that the slave got the updates even +# if the file was removed before the slave started, +# meaning that contents were indeed transfered +# through binlog (in row format) +let $diff_tables= master:t1, slave:t1; +source include/diff_tables.inc; + +# CLEAN UP +--connection master +DROP TABLE t1; +DROP PROCEDURE p; + +--source include/rpl_end.inc |
