rli->save_temporary_tables and slave_open_temp_tables
(in old 4.0 you could make "SHOW STATUS LIKE 'slave_open_temp_tables'" grow
indefinitely by doing RESET SLAVE and replicating always the same CREATE
TEMPORARY TABLE).
It's critical to reset save_temporary_tables to 0 (otherwise you may later
read memory which has been freed) so this changeset should go into 4.1.
mysql-test/r/rpl_reset_slave.result:
result update
mysql-test/t/rpl_reset_slave.test:
test for RESET SLAVE and creating twice the same temp table in the slave.
sql/slave.cc:
when we delete the slave's temp tables (when slave server shuts down and when
RESET SLAVE), we reset 2 variables: rli->save_temporary_tables & slave_open_temp_tables.
- Bug #985: "Between RESET SLAVE and START SLAVE, SHOW SLAVE STATUS is wrong."
Now RESET SLAVE puts correct info in mi->host etc. A new test rpl_reset_slave
for that.
- Bug #986: "CHANGE MASTER & START SLAVE do not reset error columns in SHOW
SLAVE STATUS". Now these reset the errors.
mysql-test/r/rpl_loaddata.result:
result update.
mysql-test/t/rpl_loaddata.test:
Test that RESET SLAVE, START SLAVE and CHANGE MASTER all reset
Last_slave_error and Last_slave_errno (columns of SHOW SLAVE STATUS).
We do it in this test because that's one of tests which have
an intentional query error on the slave.
sql/slave.cc:
As we need TWICE the code to copy command-line options (--master-host etc)
to mi (we already had it in init_master_info, but we also need it in RESET
SLAVE to fix bug#985), I make a function of this code.
And a function to reset Last_slave_error and Last_slave_errno (we need
it in CHANGE MASTER, RESET SLAVE, and at the start of the SQL thread).
sql/slave.h:
declarations for new functions.
sql/sql_repl.cc:
copy --master-host etc to mi in RESET SLAVE, so that SHOW SLAVE STATUS
shows correct information.
