by adding sleep-and-retries (max 4 times) if MASTER_POS_WAIT() returns NULL
in sync_with_master and sync_slave_with_master.
The problem showed up only today, in MySQL 5.0 in rpl_server_id2.test,
but may affect 4.x as well, so fixing it here. Note that I am also fixing
5.0 too, with the same exact patch, because I don't want to leave 5.0 broken
until the next 4.0->4.1->5.0 merge.
client/mysqltest.c:
in sync_with_master (and sync_slave_with_master), if MASTER_POS_WAIT() returns NULL,
it may be that the slave SQL thread did not have time to start yes, so we sleep
1 sec and retry, 4 times at most.
mysql-test/r/rpl_server_id2.result:
result update
mysql-test/t/rpl_server_id2.test:
master_slave.inc already drops the table
and a comment update
mysql-test/r/rpl_server_id2.result:
result update
mysql-test/t/rpl_server_id2.test:
We stop the slave before cleaning up otherwise we'll get
'drop table t1' executed twice, so an error in the slave.err
(not critical).
sql/slave.cc:
update comment about 4.1 now that 4.1 is fixed (in a few minutes, exactly)
mysql-test/r/rpl_server_id1.result:
be port-independent
mysql-test/r/rpl_server_id2.result:
be port-independent
mysql-test/t/rpl_error_ignored_table.test:
we want to sleep 2 secs, not more; if we allow ourselves to sleep >=10 seconds, then
the get_lock() will be aborted and we will arrive to late for the KILL to have
the desired effect of generating an error code in the binlog.
mysql-test/t/rpl_server_id1.test:
be port-independent
mysql-test/t/rpl_server_id2.test:
be port-independent
(WL#794). This can be of interest in some recovery-from-backup scenarios, and also when you have
two databases in one mysqld, having a certain similarity and you want one db to be updated when the other is
(some sort of trigger).
Plus small fix for BUG#3568 "MySQL server crashes when built --with-debug and CHANGE MASTER +MASTER_POS_WAIT"
sql/mysqld.cc:
new option --replicate-same-server-id
sql/slave.cc:
new option replicate_same_server_id, to force a slave to execute its own queries.
Small fix for BUG#3568 "MySQL server crashes when built --with-debug and CHANGE MASTER +MASTER_POS_WAIT"
sql/slave.h:
new option --replicate-same-server-id
