This patch removes unnecessary lock from the supremum record, takes
X-locks on duplicates also on LOAD DATA...REPLACE clause and
fixes a bug #6086 adding --disable_warnings and --enable_warnings around
the create table clauses in ctype_utf8 tests for InnoDB.
innobase/dict/dict0dict.c:
Remove static.
innobase/include/dict0dict.h:
Add prototype for a function dict_scan_to
innobase/row/row0ins.c:
Add support for a LOAD DATA INFILE 'xxx' REPLACE INTO TABLE x. We should
take X-locks on both REPLACE and LOAD DATA...REPLACE queries to duplicate
records.
innobase/row/row0sel.c:
If innodb_locks_unsafe_for_binlog options is used we do not lock
gaps. Supremum record is really a dummy record i.e. gap, therefore
we do set locks there.
mysql-test/t/ctype_utf8.test:
Fix bug #6086: Add --disable_warnings and --enable_warnings around the
create table where engine=innodb.
