This commit brings many changes, in particular two important ones: 1) Support of partitioning by connect. A table can be partitioned by files, this is an enhanced MULTIPLE table. It can be also partitioned by sub-tables like TBL and this enables table sharding. 2) Handling a CONNECT bug that causes in some cases extraneous rows to remain in the table after an UPDATE or DELETE when the command uses indexing (for not fixed file tables). Until a real fix is done, CONNECT tries to ignore indexing and if it cannot do it abort the command with an error message. - Add tests on partitioning added: storage/connect/mysql-test/connect/r/part_file.result storage/connect/mysql-test/connect/r/part_table.result storage/connect/mysql-test/connect/t/part_file.test storage/connect/mysql-test/connect/t/part_table.test - Temporary fix modified: sql/sql_partition.cc - Add partition support modified: storage/connect/ha_connect.cc storage/connect/ha_connect.h storage/connect/reldef.cpp storage/connect/reldef.h storage/connect/tabdos.cpp - Add functions ha_connect::IsUnique and ha_connect::CheckColumnList modified: storage/connect/ha_connect.cc storage/connect/ha_connect.h - Prevent updating a partition table column that is part of the partition function (outward tables only) modified: storage/connect/ha_connect.cc - Support INSERT/UPDATE/DELETE for PROXY tables modified: storage/connect/tabutil.cpp - Handle the bug on updating rows via indexing.
