marko	a658b00597	branches/zip: When shrinking the buffer pool, disable and purge the adaptive hash index, because it might occupy the chunk we would like to free. TODO: In btr_search_check_free_space_in_heap(), release the block if btr_search_latch is not immediately available. buf_pool_shrink(): Split from buf_pool_resize(). btr_search_disabled: New variable, similar to srv_use_adaptive_hash_indexes that was removed earlier. btr_search_disable(): New function: disable and purge the adaptive hash index. btr_search_enable(): New function: enable the adaptive hash index. ha_clear(): New function: Empty a hash table and free the memory heaps.	19 years ago
marko	aa2ca9f588	branches/zip: Remove some instrumentation and reduce the output of SHOW MUTEX STATUS in non-debug builds. (Bug #24386)	19 years ago
marko	e3893c65df	branches/zip: Correct a bug introduced in r1014: Always assign node->block when assigning node->data. ha_delete(), ha_search_and_delete_if_found(), ha_remove_all_nodes_to_page(): Remove the parameter buf_block_t* block, now that it is stored within the hash data structure in debug builds.	19 years ago
marko	d25fa2c4d9	branches/zip: Remove the buf_block_align() calls from ha0ha.c that caused an assertion failure in debug builds when a context switch occurred in buf_LRU_search_and_free_block() before the call to btr_search_drop_page_hash_index() managed to acquire the mutexes again. ha_node_t: Add the field buf_block_t* block. ha_search_and_update_if_found(): Rename to ha_search_and_update_if_found_func() with added buf_block_t* parameter in debug builds. Define the wrapper macro ha_search_and_update_if_found() that always takes the buf_block_t* parameter. ha_insert_for_fold(): Rename to ha_insert_for_fold_func() with added buf_block_t* parameter in debug builds. Define the wrapper macro ha_insert_for_fold() that always takes the buf_block_t* parameter.	19 years ago
marko	ce15bd43f0	branches/zip: ha_delete_hash_node(): Do not call buf_block_align(). Instead, get buf_block_t* as a parameter. Without this patch, buf_page_hash_get() would return NULL in buf_block_align(). The function buf_LRU_search_and_free_block() invokes buf_LRU_block_remove_hashed_page(), which removes the hash mapping needed by buf_page_hash_get().	19 years ago
marko	a3d72680f6	branches/zip: Add const qualifiers to read-only pointers. rec_get_nth_field_offs_old(): Split from rec_get_nth_field_old(). rec_get_nth_field_old(): Reimplement as a constness-preserving macro. dict_drop_index_tree(), dict_truncate_index_tree(): Note that rec is an in/out parameter, as the B-tree root page number will be updated.	19 years ago
marko	f52a757e24	branches/zip: ha_create(): Remove parameter in_btr_search, which was passed as TRUE. Enclose hash_table_t::adaptive and buf_block_t::n_pointers in #ifdef UNIV_DEBUG. btr_search_drop_page_hash_index(): Enclose the corruption check (which depends on buf_block_t::n_pointers) in #ifdef UNIV_DEBUG.	19 years ago
