myisam_max_extra_sort_file_size is depricated Ensure that myisam_data_pointer_size is honoured when creating new MyISAM files Changed default value of myisam_data_pointer_size from 4 to 6 to get rid of 'table-is-full' errors include/myisam.h: Change type of myisam_block_size and myisam_concurrent_insert to make them changeable in mysqld.cc Removed not used varaible myisam_max_extra_temp_length include/thr_lock.h: Added extra parameter to get_status myisam/mi_create.c: Ensure that myisam_data_pointer_size is honoured myisam/mi_dynrec.c: If 'append_insert_at_end' is set, only write at end of myisam record file myisam/mi_locking.c: Add extra argument to 'mi_get_status' to allow thr_lock to signal that we want to do a concurrent insert If this is used, we will append new insert rows at end of data file. Change mi_check_status() to allow concurrent_inserts even if there are holes in the file when myisam_concurent_insert=2 myisam/mi_static.c: Change behavior of myisam_concurrent_insert so that setting this to 2 allows inserts even if there is a hole in the data file. Default value is 2 for MyISAM direct usage but will be set to 1 (old default) by mysqld.cc myisam/mi_statrec.c: If 'append_insert_at_end' is set, only write at end of myisam record file myisam/mi_write.c: If 'append_insert_at_end' is set, only write at end of myisam record file myisam/myisamdef.h: Support for insert-at-end even if there is holes in data file mysql-test/r/gis-rtree.result: Test result changed because default value for myisam_data_pointer_size is changed from 4 -> 6 mysql-test/r/group_min_max.result: Test result changed because default value for myisam_data_pointer_size is changed from 4 -> 6 mysql-test/r/index_merge.result: Test result changed because default value for myisam_data_pointer_size is changed from 4 -> 6 mysql-test/r/index_merge_ror.result: Test result changed because default value for myisam_data_pointer_size is changed from 4 -> 6 mysql-test/r/merge.result: Test result changed because default value for myisam_data_pointer_size is changed from 4 -> 6 mysql-test/r/myisam.result: Test of concurrent_insert=2 mysql-test/r/null.result: Test result changed because default value for myisam_data_pointer_size is changed from 4 -> 6 mysql-test/r/preload.result: Test result changed because default value for myisam_data_pointer_size is changed from 4 -> 6 mysql-test/r/ps_1general.result: Test result changed because default value for myisam_data_pointer_size is changed from 4 -> 6 mysql-test/r/range.result: Test result changed because default value for myisam_data_pointer_size is changed from 4 -> 6 mysql-test/r/variables.result: concurrent_insert is now a integer, not a boolean myisam_extra_sort_file_size is deleted mysql-test/r/view.result: Test result changed because default value for myisam_data_pointer_size is changed from 4 -> 6 mysql-test/t/index_merge.test: Test result changed because default value for myisam_data_pointer_size is changed from 4 -> 6 mysql-test/t/myisam.test: Test of concurrent_insert=2 mysql-test/t/ps_1general.test: Drop test table mysql-test/t/variables.test: concurrent_insert is now a integer, not a boolean myisam_extra_sort_file_size is deleted mysql-test/t/view.test: Drop tables that may be left from previous tests mysys/thr_lock.c: Extra paramter to get_status to signal if concurrent_insert was used sql/mysqld.cc: concurrent-insert can now be set to 2 for concurrent inserts when there is holes in the data file myisam_max_extra_sort_file_size is depricated sql/set_var.cc: concurrent-insert is now an integer, not a bool myisam_max_extra_sort_file_size is deleted

sql/opt_range.cc: Fix for bug #9798: Rollup crash with InnoDB in setup_sum_funcs(). Disable mix/max group by optimization for queries with rollup for now. Note: the actual bug was hidden; if this optimization works with rollup queries we will have to change some code: the problem is that we call the join->make_sum_func_list() function against changed thd->mem_root (see SQL_SELECT::test_quick_select()) which creates some items for rollup, then we free that mem_root, then we try to reuse (free) those items.

The problem was in that the code that analyses the applicability of the QUICK_GROUP_MIN_MAX access method for DISTINC queries assumed that there are no duplicate column references in the DISTINCT clause, and it added non-exiting key parts for the duplicate column references. The solution adds a test to check whether the select list already contained a field with the same name. If such field was already present, then it was already decided to use its key part for index access. In this such case we must skip the duplicate field instead of counting it as a new field. mysql-test/r/group_min_max.result: Added test results for BUG#8532. mysql-test/t/group_min_max.test: Added tests for BUG#8532. sql/opt_range.cc: The problem was in that the code that analyses the applicability of the QUICK_GROUP_MIN_MAX access method for DISTINC queries assumed that there are no duplicate column references in the DISTINCT clause, and it added non-exiting key parts for the duplicate column references.

Split TABLE to TABLE and TABLE_SHARE (TABLE_SHARE is still allocated as part of table, will be fixed soon) Created Field::make_field() and made Field_num::make_field() to call this Added 'TABLE_SHARE->db' that points to database name; Changed all usage of table_cache_key as database name to use this instead Changed field->table_name to point to pointer to alias. This allows us to change alias for a table by just updating one pointer.

"Min/Max Optimization for Queries with Group By Clause" mysql-test/r/group_min_max.result: Added new test mysql-test/t/group_min_max.test: Added new test & comments sql/item.h: Remove processor methods that are no longer used. sql/item_sum.cc: Remove processor methods that are no longer used. sql/item_sum.h: Remove processor methods that are no longer used. sql/opt_range.cc: - the test procedure no longer needs to build lists and to traverse the expression trees - all usable indexes are tested and the bes one is chosen - added/edited function comments sql/sql_select.cc: Modified make_sum_func_list() so it can be reused in the test for MIN/MAX optimization. sql/sql_select.h: Modified make_sum_func_list() so it can be reused in the test for MIN/MAX optimization.

- after-review changes - merged with the source tree from 204-08-27 mysql-test/r/distinct.result: Different plans due to group-by optimization. sql/ha_myisam.cc: More general interface to key_copy. sql/handler.cc: More general interface to key_copy. sql/item.cc: New method to collect all Item_field objects. Used by Item::walk. sql/item.h: Several methods to collect different kinds of items from expression trees. Used by Item::walk. sql/item_sum.cc: Added helper to collect Item_sum objects. sql/item_sum.h: Methods to collect and test Item_sum objects. sql/key.cc: More general interface to key_copy and key_restore. sql/mysql_priv.h: More general interface to key_copy and key_restore. sql/opt_range.cc: Complete implementaion of WL#1724 "Min/Max Optimization for Queries with Group By Clause". sql/opt_range.h: Complete implementaion of WL#1724 "Min/Max Optimization for Queries with Group By Clause". sql/opt_sum.cc: simple_pred is re-used in opt_range.cc sql/sql_acl.cc: More general interface to key_copy and key_restore. sql/sql_handler.cc: More general interface to key_copy. sql/sql_insert.cc: More general interface to key_copy. sql/sql_select.cc: Changes to hook the new QUICK_GROUP_MIN_MAX_SELECT due to two differences from all other quick selects: 1) This quick select may be created (and used) even if there is no WHERE clause. Several places assumed that a QUICK_SELECT is constructed only if there is a WHERE clause, which had to be changed so that QUICK_GROUP_MIN_MAX can be used. 2) Unlike all other quick selects, this QUICK_GROUP_MIN_MAX_SELECT operates for GROUP BY queries. Since for the caller the quick select already produces one result tuple per group, there is no need to call end_send_group, instead we have to call end_send as for a regular quick select. sql/sql_select.h: simple_pred is re-used in opt_range.cc
