Added innodb_locks_unsafe_for_binlog option. This option turns off Innodb
next-key locking. Using this option the locks InnoDB sets on index
records do not affect the ``gap'' before that index record. Thus, this option
allows phantom problem.
innobase/include/srv0srv.h:
Added srv_locks_unsafe_for_binlog for innodb_locks_unsafe_for_binlog option.
innobase/row/row0sel.c:
If innodb_locks_unsafe_for_binlog option is used, we lock only the record, i.e.
next-key locking is not used. Therefore, setting lock to the index record
do not affect the ``gap'' before that index record. Thus, this option
allows phantom problem, because concurrent insert operations are allowed inside
the select range.
innobase/srv/srv0srv.c:
Added srv_locks_unsafe_for_binlog for innodb_locks_unsafe_for_binlog option.
sql/ha_innodb.cc:
Added innobase_locks_unsafe_for_binlog and srv_locks_unsafe_for_binlog for
innodb_locks_unsafe_for_binlog option.
sql/ha_innodb.h:
Added innobase_locks_unsafe_for_binlog for innodb_locks_unsafe_for_binlog option.
sql/mysqld.cc:
Added OPT_INNODB_LOCKS_UNSAFE_FOR_BINLOG, innobase_locks_unsafe_for_binlog for
innodb_locks_unsafe_for_binlog option.
sql/set_var.cc:
Added innodb_locks_unsafe_for_binlog and innobase_locks_unsafe_for_binlog for
innodb_locks_unsafe_for_binlog option.
