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	8478f3824c	branches/zip: btr_store_big_rec_extern_fields(): Remove the incomplete statement that was accidentally checked in in r1022.	19 years ago
marko	ebeee34510	btr_store_big_rec_extern_fields(): Write the (space_id, page_no) of the record on every compressed BLOB page header, so that compressed BLOBs can be relocated or the chain of BLOB pages can be validated.	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	fc86d41650	branches/zip: buf_block_align(): Remove from non-debug builds. btr_search_guess_on_hash(), btr_search_validate(): Instead of buf_block_align(), call buf_page_hash_get(), and allow it to return NULL.	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	694f267391	branches/zip: Always call buf_block_align() while holding buf_pool->mutex. This was forgotten from r977.	19 years ago
marko	69fc883be2	branches/zip: Remove support for AWE (Intel PAE on Win32). Removal of the variable innobase_buffer_pool_awe_mem_mb requires coordination with MySQL AB.	19 years ago
marko	497a2ef429	branches/zip: Minor cleanup. btr_pcur_restore_position(): Add const qualifiers. buf_LRU_block_remove_hashed_page(): Reduce the amount of buf_page_hash_get() calls and add a UNIV_UNLIKELY hint to an assertion-like test.	19 years ago
marko	a052088f48	branches/zip: btr_lift_page_up(): Omit father_block from blocks[], because the level of that page needs to be adjusted separately.	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	dfb8add7b3	branches/zip: btr_store_big_rec_extern_fields(): Replace page_get_page_no(page_align(field_ref)) calls with a local variable rec_page_no = buf_block_get_page_no(rec_block).	19 years ago

marko	c1286aa47e	branches/zip: Merge revisions 887:934 from trunk.	19 years ago
marko	9ac3df7687	branches/zip: Remove a few buf_block_align() calls from debug builds. btr_check_node_ptr(): Replace page_t* parameter with buf_block_t*. btr_free_externally_stored_field(): Add const qualifier to rec. Remove an explicit buf_block_align() call, but replace an mtr_memo_contains() with mtr_memo_contains_page(). row_upd_rec_sys_fields(): Reorder an assertion containing buf_block_align() so that the costly call can be avoided in some cases.	19 years ago
marko	42dcad50b8	branches/zip: Remove all references to buf_block_align() except those from the adaptive hash index [btr_search_guess_on_hash() and btr_search_validate()]. Some references to buf_block_align() remain in debug builds. btr_store_big_rec_extern_fields(): Add the parameter rec_block. page_rec_get_next_low(): Do not assume that the page has been allocated from the buffer pool when printing the diagnostic information. page_cur_insert_rec_low(): Replace the parameter page_zip_des_t* page_zip with the parameter buf_block_t* block.	19 years ago
marko	9b0a89867e	branches/zip: Remove all buf_block_align() calls from lock0lock.c. Replace all page_t* parameters with buf_block_t, and replace many rec_t parameters with heap_no. This eliminates also many rec_get_heap_no() calls, which became more expensive with the introduction of ROW_FORMAT=COMPACT in MySQL/InnoDB 5.0.3. page_rec_get_heap_no(), lock_get_min_heap_no(): New functions.	19 years ago
marko	7e8c129370	branches/zip: buf_page_get_release_on_io(), buf_page_get_gen(): Replace buf_frame_t* guess with buf_block_t* guess in order to avoid a buf_block_align() call. trx_undo_t: Replace page_t* guess_page with buf_block_t* guess_block. btr_search_t: Replace page_t* root_guess with buf_block_t* root_guess.	19 years ago
marko	009533b471	branches/zip: Minor cleanup. page_set_max_trx_id(): Replace page_t* parameter with buf_block_t*, to avoid a buf_block_align() call. Replace some occurrences of page_get_page_no() with buf_block_get_page_no(). page_cur_delete_rec(): Replace buf_block_align() with page_cur_get_block().	19 years ago
marko	f97f00ee60	branches/zip: Fix some bugs. btr_cur_pessimistic_insert(): Remove local variable "block". Replace an extraneous call to btr_cur_position() [with wrong "block", in r948] with a debug assertion that the cursor is positioned on the preceding record after the page split. btr_pcur_restore_position(): Do not use btr_pcur_get_page(), because the debug assertion there could fail. This bug was introduced in r928.	19 years ago
marko	8e33825034	branches/zip: btr_search_drop_page_hash_index(): Do not call buf_block_get_frame(), because it will lead to debug assertion failure when buf_fix_count == 0. This bug was introduced in r908.	19 years ago
marko	8562e752bc	branches/zip: Remove some more buf_block_align() calls. btr_cur_t: Move page_block to page_cur_t::block. page_cur_get_block(), page_cur_get_page_zip(): New functions. page_cur_position(): Add parameter block. Remove many page_zip parameters, now that there is page_cur_get_page_zip(). Replace some page, page_zip parameters with block. Add some const qualifiers to function parameters and remove casts. PAGE_HEAP_NO_INFIMUM, PAGE_HEAP_NO_SUPREMUM, PAGE_HEAP_NO_USER_LOW: New constants. Replace some cursor code in low-level diagnostic functions with direct management of rec, because buf_block_t::buf_fix_count may be 0 when the functions are called, and debug assertions would fail.	19 years ago
marko	3e1c60b96f	branches/zip: btr_search_guess_on_hash(): Do not call buf_block_get_frame(), because it will lead to debug assertion failure when buf_fix_count == 0. This bug was introduced in r912.	19 years ago
marko	5a5e163f50	branches/zip: btr_cur_open_at_index_side(): Correct a debug assertion added in r928. Do not call btr_cur_get_block() in the debug assertion, because the debug assertion there would fail.	19 years ago

marko	91f8a3dde5	branches/zip: Remove many fil_space_get_zip_size() calls. ibuf_page(), ibuf_page_low(), ibuf_free_excess_pages(), ibuf_insert(), buf_read_page(), buf_read_ahead_linear(), buf_read_recv_pages(): Add parameter zip_size.	19 years ago
marko	a3860f7126	branches/zip: Remove some more buf_block_align() calls. btr_search_build_page_hash_index(), fsp_parse_init_file_page(), ibuf_parse_bitmap_init(): Replace page_t* with buf_block_t. buf_read_ibuf_merge_pages(): Add const qualifiers.

marko	e8a779e73e	branches/zip: Remove the casts introduced in r920 and r925. Replace the accessors returning pointers with macros that preserve const qualifiers. In UNIV_DEBUG builds, retain the accessors and cast away constness there. dfield_get_type(), dfield_get_data(), dtuple_get_nth_field(), dict_table_get_nth_col(), dict_table_get_sys_col(): Implement as macro unless #ifdef UNIV_DEBUG. rec_get_nth_field(): Replace with rec_get_nth_field_offs() that does not do pointer arithmetics. Implement rec_get_nth_field() as a macro.	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
marko	ab0456cb5e	branches/zip: btr_cur_t: replace left_page with left_block, to avoid calling buf_block_align() in btr_pcur_move_backward_from_page(). Also, enclose some assertions about page_is_comp() in #ifdef UNIV_BTR_DEBUG.	19 years ago
marko	c659b59a5d	branches/zip: Eliminate many buf_block_align() calls. Replace page_t* or page_zip_des_t* parameters in some functions with buf_block_t. buf_frame_get_page_zip(): Disable unless #ifdef UNIV_DEBUG \|\| UNIV_ZIP_DEBUG. btr_cur_t: Add buf_block_t page_block. btr_pcur_get_block(), btr_cur_get_block(), btr_cur_get_page_zip(): New functions. btr_cur_position(): Add the parameter block.	19 years ago
marko	6bf52fdaca	branches/zip: Introduce const qualifiers to many read-only parameters and modify some functions to return const pointers. Add const qualifiers to local variable declarations or casts to remove the const qualifier in those places where write access is needed.	19 years ago
marko	70e765aeb3	branches/zip: Remove some more buf_block_align() calls. Replace buf_frame_modify_clock_inc() with buf_block_modify_clock_inc(). Replace buf_frame_get_lock_hash_val() with buf_block_get_lock_hash_val(). Replace buf_frame_get_lock_mutex() with buf_block_get_lock_mutex(). page_create_zip(), page_create(), page_create_low(), btr_page_free(), btr_page_free_low(): Replace page_t with buf_block_t.	19 years ago
marko	0fa8df757f	branches/zip: Eliminate some more buf_block_align() calls. ibuf_update_free_bits_low(), ibuf_update_free_bits_for_two_pages_low(), ibuf_set_free_bits_low(): Replace page_t with buf_block_t.	19 years ago
marko	138ee61049	branches/zip: Remove more references to buf_block_align(). ibuf_reset_free_bits(): Remove, as there already is a similar function ibuf_reset_free_bits_with_type(). ibuf_reset_free_bits_with_type(), ibuf_set_free_bits(), ibuf_update_free_bits_if_full(), btr_leaf_page_release(), buf_page_make_young(): Replace page_t with buf_block_t. btr_compress(): Replace btr_page_get() with btr_block_get().	19 years ago

marko	a208526186	branches/zip: Replace buf_frame_alloc() and buf_frame_free() with buf_block_alloc() and buf_block_free(), in order to avoid buf_block_align() calls.	19 years ago
marko	c755e88727	branches/zip: Reduce the number of buf_block_align() calls. btr_block_get(): New function to return buf_block_t. btr_page_alloc(), buf_page_get_release_on_io(), buf_page_get_gen(), buf_page_create(), fseg_create(), fseg_create_general(): Return buf_block_t. buf_page_get_known_nowait(): Expect buf_block_t instead of buf_frame_t. buf_frame_get_newest_modification(): Replace with buf_block_get_newest_modification(). buf_page_dbg_add_level(): Replace with buf_block_dbg_add_level(). buf_block_get_zip_size(): New function. buf_block_get_page_zip(): Reintroduce. recv_recover_page(): Replace page, space, page_no with block. ibuf_bitmap_page_init(): Replace page, zip_size with block. ibuf_parse_bitmap_init(): Remove the parameter zip_size. btr_search_drop_page_hash_index(): Replace page with block.	19 years ago
marko	d61d296ccd	branches/zip: Replace buf_frame_get_page_no() and buf_frame_get_space_id() with page_get_page_no() and page_get_space_id(). We want to avoid buf_block_align() calls, and the page_no and space_id are now stamped on the pages early on.	19 years ago
marko	5a10ee2721	branches/zip: Add function mtr_memo_contains_page() #ifdef UNIV_DEBUG. Replace ut_ad(mtr_memo_contains(mtr, buf_block_align(ptr), ...)) with ut_ad(mtr_memo_contains_page(mtr, ptr, ...)) in order to reduce the number of buf_block_align() calls.	19 years ago

marko	11cd834bb1	branches/zip: buf_block_get_page_zip(): Replace with buf_frame_get_page_zip().	19 years ago
marko	a4c9d38ee8	branches/zip: Fix all bugs detected by mysql-test-run. The exactly same set of tests are failing with trunk -r869, with this revision using uncompressed storage, and with this revision hard-wired to use 1-kilobyte compressed pages and innodb_file_per_table. btr_push_update_extern_fields(): Do not call ut_ulint_sort() if n_pushed == 0. btr_copy_externally_stored_field_prefix_low(): Replace ut_max() with ut_min().	19 years ago
marko	77ebaf6f33	branches/zip: dtuple_convert_big_rec(): Do not store anything locally of externally stored columns, and fix bugs introduced in r873. (Bug #22496) btr_page_get_sure_split_rec(), btr_page_insert_fits(), rec_get_converted_size(), rec_convert_dtuple_to_rec(), rec_convert_dtuple_to_rec_old(), rec_convert_dtuple_to_rec_new(): Add parameters ext and n_ext. Flag external fields during the conversion. rec_set_field_extern_bits(), rec_set_field_extern_bits_new(), rec_offs_set_nth_extern(), rec_set_nth_field_extern_bit_old(): Remove. The bits are set by rec_convert_dtuple_to_rec(). page_cur_insert_rec_low(): Remove the parameters ext and n_ext. btr_cur_add_ext(): New utility function for updating and sorting ext[]. Low-level functions now expect the array to be in ascending order for performance reasons. Used in btr_cur_optimistic_insert(), btr_cur_pessimistic_insert(), and btr_cur_pessimistic_update(). btr_cur_optimistic_insert(): Remove some defensive code, because we cannot compute the added parameters of rec_get_converted_size(). btr_push_update_extern_fields(): Sort the array. Require the array to be twice the maximum usage, so that ut_ulint_sort() can be used. dtuple_convert_big_rec(): Allocate new space for the BLOB pointer, to avoid overwriting prefix indexes to the same column. Adapt dtuple_convert_back_big_rec(). row_build_index_entry(): Fetch the columns also for prefix indexes of the clustered index. page_zip_apply_log(), page_zip_decompress_clust(): Allow externally stored fields to lack a locally stored part.	19 years ago
marko	b02b07bc9a	btr_page_get_sure_split_rec(): Revert the change from r875: "On compressed pages, return NULL if incl_data > free_space." btr_page_split_and_insert(): Remove the limit check of n_iterations on compressed pages. After enough many invocations of btr_page_get_sure_split_rec(), the record will finally fit.	19 years ago
marko	ab0f3d6b81	branches/zip: btr_page_get_sure_split_rec(): Rewrite the for (;;) { ... if (condition) { ... return }} loop as do { ... } while (!condition); ... return. On compressed pages, return NULL if incl_data > free_space.	19 years ago
marko	9d2146e431	branches/zip: Replace FIL_PAGE_ZBLOB_SPACE_ID and FIL_PAGE_ZBLOB_DATA with FIL_PAGE_ARCH_LOG_NO_OR_SPACE_ID and FIL_PAGE_DATA. The doublewrite buffer needs to read the space_id in order to determine the type of the page. Because FIL_PAGE_TYPE could contain garbage in MySQL/InnoDB 5.0 and earlier versions, we cannot trust fil_page_get_type(). Instead, we have to always store the space_id at the same location. This modification wastes 12 bytes per compressed BLOB page (1.2% on 1-kilobyte pages).	19 years ago
marko	22c95e9a63	branches/zip: Add const qualifiers to the pointer parameters of mach_read_...() functions. Remove unnecessary casts.	19 years ago
marko	6e269ddf34	branches/zip: Implement the ability to fetch a prefix of an externally stored column. This is the first part of fixing Bug #22496. btr_copy_externally_stored_field_prefix(): New function. btr_copy_externally_stored_field(): Split to btr_copy_externally_stored_field_prefix_low(). row_sel_sec_rec_is_for_blob(): New function, used by row_sel_sec_rec_is_for_clust_rec() in selects via a secondary index.	19 years ago
