Problem: mysqlbinlog_base64 failed sporadically.
Reason: Missing "flush logs" before running $MYSQL_BINLOG,
which could start dumping the log file before server
has finished writting into it.
Fix:
- implementing --force-if-open option to "mysqlbinlog"
- adding --disable-force-if-open to make $MYSQL_BINLOG
fail on non-closed log files, to garantee that nobody
will forget "flush logs" in the future.
- adding "flush logs" into all affected tests.
Rename mix_innodb_myisam_binlog-master.opt; when the test was moved to
separate stm/row test cases, the .opt were not moved along with it,
causing a 60-second test duration because of default lock timeout :-(
