marko	e1c3be5e03	branches/zip: Rename mem_heap_calloc() and mem_calloc() to mem_heap_zalloc() and mem_zalloc(), because calloc() in the C runtime library takes two size parameters, not one. mem_heap_zalloc(): Add debug assertions. Document that the return value is never NULL.	19 years ago
marko	5288876e23	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	f29addba49	branches/zip: Enable calls to inlined InnoDB functions in ha_innodb.cc, now that all of InnoDB code is built from a single Makefile and it should not be possible to build the modules with mutually incompatible options. #define INSIDE_HA_INNOBASE_CC: Remove. srv_sizeof_trx_t_in_ha_innodb_cc: Remove. dict_table_get_low_noninlined(): Remove. This function was unused. Remove all _noninline functions. Remove the _noninline suffix from all function calls in ha_innodb.cc.	19 years ago
marko	71e8cceeab	branches/zip: Define mem_heap_calloc() and mem_calloc(). Use them when allocating zero-filled memory.	19 years ago
marko	d75e64f98a	branches/zip: Merge 1493:1533 from trunk. Make use of UT_BITS_IN_BYTES().	19 years ago
marko	ac6fb591bb	branches/zip: Rename dtuple_datas_are_ordering_equal() to dtuple_coll_cmp(), and change the return type from ibool to int (-1, 0, 1). This comparison function will be needed in fast index creation.	19 years ago
marko	e7284367dc	branches/zip: Merge revisions 1402:1493 from trunk. Remove mysql.patch, because the configuration parameter interface has changed.	19 years ago
marko	a47b9e64e6	branches/zip: Merge branches/fast-index-creation -r1413. Fix some bugs. The tests innodb and innodb-index fail, but that might be due to an old MySQL source tree being used.	19 years ago
marko	e4d8b192fe	branches/zip: Make dtuple_big_rec_free() an inline function.	19 years ago
marko	c712838401	branches/zip: Merge revisions 1165:1206 from trunk.	19 years ago
marko	98a829723c	branches/zip: Add const qualifiers to function parameters, mostly dtuple_t.	19 years ago
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	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	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	2884c83de6	branches/zip: dtuple_convert_big_rec(): Reduce the locally stored part of externally stored columns to REC_1BYTE_OFFS_LIMIT (128) bytes. TODO: only store BTR_EXTERN_FIELD_REF_SIZE (20) bytes with the record, and store the entire column externally. (Bug #22496) dict_col_t::min_prefix: Remove.	19 years ago
marko	9a16aac783	branches/zip: Merge revisions 804:838 from trunk.	19 years ago
marko	6429e2e682	branches/zip: dtuple_convert_big_rec(): Shorten the locally stored part of externally stored columns to 108 bytes when possible. This will unmask a bug in the handling of BLOBs on compressed tablespaces, especially of small page sizes. Apparently, the locally stored part must be less than 235 bytes in size for the bug to occur. dict_col_struct: Add field min_prefix. dict_index_build_internal_non_clust(): Adjust min_prefix.	20 years ago
marko	64f3cee67f	branches/zip: Merge revisions 720:765 from trunk and reindent the code as per revisions r763:765.	20 years ago
marko	7291e6579e	branches/zip: dtuple_convert_big_rec(): Do not attempt to shorten records of secondary indexes. (This is just an optimization; the logic in the search loop would never store such records externally.)	20 years ago
marko	49c9bbd81e	branches/zip: Bug fixes. data0data.c: Add #include "page0zip.h" that was forgotten from r739. page_cur_insert_rec_low(): Remove a memory leak when preventing extra_size to grow.	20 years ago
marko	ae8901c8c9	branches/zip: Account for the compressed page size when checking if a record will fit or need external storage. btr_page_get_sure_split_rec(): Estimate the free space of an empty compressed page. page_zip_rec_needs_ext(): New function, to replace existing tests whether external storage is needed.	20 years ago
marko	645e56909f	branches/zip: Merge revisions 583:634 from trunk.	20 years ago
marko	450bbd7c3b	branches/zip: Merge revisions 265:459 from trunk.	20 years ago
marko	ed3d577301	branches/zip: Minor cleanup. Replace btr_page_get_level() with page_is_leaf() where possible. row_purge_upd_exist_or_extern(): Remove obsolete TODO comment. dtuple_convert_big_rec(): Replace a flag variable with goto.	20 years ago
marko	82d38b63e3	branches/zip: Merge revisions 236:247 from trunk.	20 years ago
marko	f40121415d	branches/zip: Merge revisions 200:236 from trunk.	20 years ago
marko	6ce8427cb8	branches/zip: Merge revisions 79:200 from trunk.	20 years ago
marko	d8e3b8114c	branches/zip: Remove in-place updates of the "external storage" flag of records. The flags may only be updated in heap-allocated copies of records. btr_root_raise_and_insert(), btr_page_split_and_insert(), btr_cur_insert_if_possible(), btr_cur_optimistic_insert(), btr_cur_pessimistic_insert(), page_cur_tuple_insert(), page_cur_insert_rec_low(): Add parameters "ext" and "n_ext". dtuple_convert_big_rec(): Make parameter "ext" const.	20 years ago
osku	c307820962	Import 5.0 code.	20 years ago
