marko	c09dd214be	branches/zip: Add const qualifiers to the upd_t* parameters of some functions.	19 years ago
marko	f2744d505b	branches/zip: row_upd_sec_index_entry(): Pass foreign=TRUE to row_ins_index_entry(). The added parameter (whether to check foreign key constraints) was incorrectly passed as FALSE in r1591.	19 years ago
marko	632ec54002	branches/zip: Make merge sort handle externally stored columns. Some things still fail in innodb-index.test, and there seems to be a race condition (data dictionary lock wait) when running with --valgrind. dfield_t: Add an "external storage" flag, dfield->ext. dfield_is_null(), dfield_is_ext(), dfield_set_ext(), dfield_set_null(): New functions. dfield_copy(), dfield_copy_data(): Add const qualifiers, fix in/out comments. data_write_sql_null(): Use memset(). big_rec_field_t: Replace byte* data with const void* data. ut_ulint_sort(): Remove. upd_field_t: Remove extern_storage. upd_node_t: Replace ext_vec, n_ext_vec with n_ext. row_merge_copy_blobs(): New function. row_ins_index_entry(): Add the parameter "ibool foreign" for suppressing foreign key checks during fast index creation or when inserting into secondary indexes. btr_page_insert_fits(): Add const qualifiers. btr_cur_add_ext(), upd_ext_vec_contains(): Remove. dfield_print_also_hex(), dfield_print(): Replace if...else if with switch. Observe dfield_is_ext().	19 years ago
marko	7e687905be	branches/zip: Add some const qualifiers, mainly to upd_t*. upd_get_n_fields(), upd_get_nth_field(): Add const qualifiers.	19 years ago
marko	a369b00981	branches/zip: btr_cur_pessimistic_update(): Add parameter heap. Previously, when big_rec was returned, the fields would point to freed memory. The memory heap was allocated locally, and the data tuple was allocated from the heap, and the big_rec would point to some fields in the data tuple. row_ins_clust_index_entry_by_modify(): Add parameter heap, for the same reason.	19 years ago
marko	7fbc4f2bc0	branches/zip: Merge revisions 1009:1165 from trunk.	19 years ago
marko	c1ffbbd90f	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	438cb8a6c1	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	d6c684798e	branches/zip: Add const qualifiers to function parameters, mostly dtuple_t.	19 years ago
marko	fbe4fe6022	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	d583b1803c	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	8f07794024	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	d374183221	branches/zip: buf_block_get_page_zip(): Replace with buf_frame_get_page_zip().	19 years ago
marko	174bd7b7ca	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	1f510066f4	branches/zip: Allow the locally stored part of externally stored columns in the clustered index to be smaller than the indexed prefix in secondary indexes. row_ext_lookup(): Return NULL if the column is not stored externally. trx_undo_rec_get_partial_row(): row_build(): Add parameter row_ext_t** ext. row_build_index_entry(): Add the parameter row_ext_t* ext. Invoke row_ext_lookup() to fetch prefixes of externally stored columns. upd_node_t, undo_node_t, purge_node_t: Add the field row_ext_t* ext.	19 years ago
marko	8e59e994ac	branches/zip: Minor cleanup in update related code. btr_push_update_extern_fields(): Instead of iterating all upd_get_n_fields(), stop at the first match. row_search_index_entry(): Simplify the return statements. row_upd_sec_step(): Eliminate the local variable "err". row_upd_clust_step(): Add a UNIV_UNLIKELY hint.	19 years ago
marko	9c6947fd4d	branches/zip: Merge revisions 838:861 from trunk.	19 years ago
marko	68a65c142c	branches/zip: Merge revisions 804:838 from trunk.	19 years ago
marko	38e09b2fea	branches/zip: Merge revisions 720:765 from trunk and reindent the code as per revisions r763:765.	19 years ago
marko	00ddce117d	branches/zip: Minor cleanup. row_upd_sec_index_entry(): Remove redundant goto. Replace duplicated cleanup code with goto func_exit. mtr_memo_slot_release(): Eliminate the #else branch of #ifdef UNIV_DEBUG by reorganizing the code.	20 years ago
marko	7f8cb7aab9	branches/zip: Merge revisions 583:634 from trunk.	20 years ago
marko	d30e44bc32	branches/zip: Merge revisions 465:532 from trunk.	20 years ago
marko	0c4dfda3be	branches/zip: Merge revisions 265:459 from trunk.	20 years ago
marko	cd7583af1f	branches/zip: Minor fixes trx-undo_prev_version_build(): Pass offsets==NULL to rec_set_field_extern_bits(). rec_set_field_extern_bits(), rec_set_field_extern_bits_new(): Accept offsets==NULL. row_upd_rec_in_place(): Remove the bogus comment that the function would only be invoked on a clustered index. Remove the related debug assertion.	20 years ago
marko	65dfefe2c2	branches/zip: Implement in-place updates of BLOB pointers. There are still some bugs in the code. btr_store_big_rec_extern_fields(): Remove assertion on dict_table_is_zip() to ease testing. btr_free_externally_stored_field(): Test page_zip instead of dict_table_is_zip(). page_zip_write_rec(): Add parameter "create". Try to handle externally stored columns. rec_offs_any_extern(): Correct the function comment. Add rec_offs_n_extern() and page_zip_get_n_prev_extern(). page_zip_dir_decode(): Replace assertion with if (...) return(FALSE). page_zip_decompress(): Do not clear page_zip->n_blobs after counting the BLOBs. page_zip_write_blob_ptr(): Use page_zip_get_n_prev_extern(). Correct an off-by-one error in memcpy().	20 years ago
marko	23d19f8f4b	branches/zip: Minor improvements. btr_cur_pessimistic_update(): Remove extraneous page_zip_write_rec() call. btr_cur_set_ownership_of_extern_field(): Simplify the logic. row_upd_rec_in_place(): Make use of parameter "index" in debug assertions. page_zip_write_rec(): Remove TODO comment about redo log record. The write will already be covered by higher-level log entries.	20 years ago
marko	e8e9fb28b4	branches/zip: Note that TRX_ID and ROLL_PTR only exist on B-tree leaf pages of clustered indexes. Previously, parts of the code assumed that these columns would exist on all leaf pages. Simplify the update-in-place of these columns. Add inline function dict_index_is_clust() to replace all tests index->type & DICT_CLUSTERED. Remove the redo log entry types MLOG_ZIP_WRITE_TRX_ID and MLOG_ZIP_WRITE_ROLL_PTR, because the modifications to these columns are covered by logical logging. Fuse page_zip_write_trx_id() and page_zip_write_roll_ptr() into page_zip_write_trx_id_and_roll_ptr(). page_zip_dir_add_slot(), page_zip_available(): Add flag "is_clustered", so that no space will be reserved for TRX_ID and ROLL_PTR on leaf pages of secondary indexes. page_zip_apply_log(): Flag an error when val==0 is encoded with two bytes. page_zip_write_rec(): Add debug assertions that there is enough space available for the entry before copying the data bytes of the record.	20 years ago
marko	1aca6cada1	branches/zip: Fix some bugs in the insertion of records. row_upd_rec_in_place(), page_zip_write_rec(): Add parameter "index". page_dir_set_n_heap(): Add a debug assertion that on compressed pages, n_heap will always be incremented by one. Improve code formatting. page_zip_dir_add_slot(): New function, called from page_cur_insert_rec_low() after page_mem_alloc_heap(). rec_set_n_owned_new(): Do not call page_zip_rec_set_owned() on the supremum record. rec_offs_make_valid(): Add debug assertions. page_zip_dir_user_size(): Correct an off-by-one error in the debug assertion. page_zip_apply_log(): Add parameter trx_id_col. Skip trx_id and roll_ptr. page_zip_decompress(): Simplify the handling of "storage" in the loop that copies the uncompressed fields. page_zip_write_rec(): Store trx_id and roll_ptr separately. page_zip_write_trx_id(), page_zip_write_roll_ptr(): Fix off-by-one errors. page_cur_insert_rec_low(): Call page_zip_dir_add_slot() after page_mem_alloc_heap(). Remove some redundant assertions. Pass page_zip to page_dir_split_slot().	20 years ago

marko	12050c5c1c	branches/zip: Prepare for in-place updates of B-tree node pointers, BLOB pointers, trx_id, and roll_ptr. btr_empty(), btr_create(), page_create(): Add parameter "index", as some index information will be encoded on the compressed page. Define REC_NODE_PTR_SIZE as 4. Allow btr_page_reorganize() and btr_page_reorganize_low() to fail. Define the error code DB_ZIP_OVERFLOW. Make row_ins_index_entry_low() static. page0zip: Encode the index, log reorganized records, and store uncompressed fields separately from the compressed data stream.	20 years ago
marko	10fffd0dc5	branches/zip: Remember to update page_zip when updating "extern" flags. Add function parameters and TODO comments regarding that.	20 years ago
