WL#2985 "Partition Pruning": post-review fixes: - Added more comments. - Added a RANGE_OPT_PARAM::remove_jump_scans flag that disables construction of index_merge SEL_TREEs that represent unusable conditions like "key1part1<c1 OR key2part2<c2" - make prune_partitions() function handle the case where range analysis produces a list of index_merge trees (it turned out that this is possible, appropriate test case added). - Other small fixes. mysql-test/r/partition_pruning.result: WL#2985 "Partition Pruning": post-review fixes: more test cases mysql-test/t/partition_pruning.test: WL#2985 "Partition Pruning": post-review fixes: more test cases sql/opt_range.cc: WL#2985 "Partition Pruning": post-review fixes: - Added more comments. - Fix the debug printouts - Added a RANGE_OPT_PARAM::remove_jump_scans flag that disables construction of index_merge SEL_TREEs that represent unusable conditions like "key1part1<c1 OR key2part2<c2" - make prune_partitions() function handle the case where range analysis produces a list of index_merge trees (it turned out that this is possible, appropriate test case added). sql/sql_partition.cc: WL#2985 "Partition Pruning": post-review fixes: make requested edits in comments. sql/table.h: WL#2985 "Partition Pruning": post-review fixes: added bool TABLE::no_partitions_used (this change was missed when making the original cset)
