Now we don't take any mutexes when creating or dropping internal HEAP tables during SELECT. Change buffer sizes to size_t to make keycache 64 bit safe on platforms where sizeof(ulong) != sizeof(size_t) BitKeeper/etc/ignore: added support-files/mysqld_multi.server include/heap.h: Added 'internal_table' to HP_CREATE_INFO include/keycache.h: Change buffer sizes to size_t to make keycache 64 bit safe include/my_base.h: Added HA_OPEN_INTERNAL_TABLE to mark temporary tables that should be deleted on close mysys/mf_keycache.c: Change buffer sizes to size_t to make keycache 64 bit safe sql/sql_select.cc: Added HA_OPEN_INTERNAL_TABLE to mark temporary tables that should be deleted on close Removed not anymore needed call to delete_table() storage/heap/ha_heap.cc: Added support for internal temporary tables that should be deleted on close. Internal tables now use dedicated open and close calls to avoid taking mutexes. If heap_open() failes, now delete the newly created table. (This fixes a possible memory leak) Remove never executed info() in create() storage/heap/ha_heap.h: Added slots needed to handle internal temporary tables storage/heap/heapdef.h: Protect against C++ inclusion storage/heap/hp_close.c: Don't call list_delete() for internal temporary tables (They are not in the list) storage/heap/hp_create.c: Added HP_SHARE ** element to heap_create() to store the SHARE of the newly created table. For internal temporary tables: Don't take any mutex and don't put them into the open table list. storage/heap/hp_open.c: Split heap_open() into sub functions to be able to create internal temporary tables without putting them in the heap_share_list. Add faster open() functions for when we already know the 'share'. storage/heap/hp_test1.c: Update call to heap_create() Initialize all keyinfo members. storage/heap/hp_test2.c: Update call to heap_create() |
