Move more definitions from row0mysql.h to row0mysql.c. Remove the
unused definition of merge_thread.
merge_index_def_t: Replace merge_index_field_t** with merge_index_field_t*.
Use mem_heap_strdup() when copying strings.
ha_innobase::add_index(): Avoid excessive use of current_thd.
assignments. A memory leak remains at "goto error_handling": the memory
allocated with row_merge_block_create() in the beginning of this function
will not be freed.
Define the merge_rec_ structures in row0merge.c instead of
row0merge.h. They are not used in the interface defined in row0merge.h.
row_merge_create_file_structure(): Rename to row_merge_file_create().
Input a pointer to a pre-allocated block of memory.
row_merge_read_clustered_index(): Replace merge_file_t** with merge_file_t*.
row_merge_sort_and_insert_thread(): Remove the declaration.
This function was never defined or called.
row_merge_is_index_usable(): Correct the formatting.
row_build_index_for_mysql(): Allocate an array of merge_file_t instead
of an array of pointers to merge_file_t.
innodb.test: The error code 1540 has been renumbered to 1542.
innodb.result: Adjust the expected value of Innodb_buffer_pool_pages_total.
Something may have changed in the BLOB handling in branches/zip.
ha_innodb.cc: Add ha_innobase:: prefix to some DBUG_ENTER macros.
row_merge_create_temporary_table(): Free the heap only after invoking
row_create_table_for_mysql(). The table->col_names points to the heap
until the system columns are added by row_create_table_for_mysql().
TODO: use the filename-safe encoding in temporary table names. Test
extensively under Valgrind and fix all errors found. Eliminate
merge_rec_t and rewrite row0merge.c to write the records directly to
the merge blocks.
dict_truncate_index_tree(): Add the parameter space for specifying the
new tablespace identifier of a single-table tablespace that has been
recreated. When SYS_INDEXES.PAGE_NO == FIL_NULL, do not abort but
create the index tree.
fil_discard_tablespace(): Pass the return code from fil_delete_tablespace().
row_truncate_table_for_mysql(): Attempt to discard and recreate
single-table tablespaces. Reassign the tablespace identifier both in
the data dictionary (SYS_TABLES and SYS_INDEXES) and in the data
dictionary cache.
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.
buf_page_get_gen(). This saves one mutex operation per block request.
buf_page_get_gen(), various macros and functions: Add parameter zip_size.
btr_node_ptr_get_child(): Add parameter index.
fil_space_get_latch(): Add optional output parameter zip_size.
fil_space_get_zip_size(): Return 0 for space id==0, because the
system tablespace is never compressed.
fsp_header_init(): Remove the parameter zip_size.
ibuf_free_excess_pages(): Remove the parameter zip_size.
trx_rseg_t, trx_undo_t: Add field zip_size.
xdes_lst_get_next(): Remove, unused.
introduced ib_longlong and %ll length specifier are not C89.)
row_ext_t: Change char* buf to byte* buf to avoid signedness warnings.
Change the type of all bit fields to unsigned.
rec_get_next_ptr(): Add (byte*) casts to avoid arithmetics on void*.
page_zip_decompress_clust(): Do not mix declarations and code.
Do not break the latching order in TRUNCATE TABLE.
dict_truncate_index_tree(): Replace parameter rec_t* rec with
btr_pcur_t* pcur. Reposition pcur before calling btr_create().
sync_thread_add_level(): Remove the relaxation of the assertion added in r968.
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.
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.
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.
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.
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.
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.
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.
Do not augment clustered index records. When computing the prefix,
use dfield (where the prefix was copied), not dfield2 (the record in
the clustered index).
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.
This will be needed for fixing Bug #22496.
REC_MAX_INDEX_COL_LEN: New constant, copied from DICT_MAX_INDEX_COL_LEN.
row_ext_create(), row_ext_lookup(), row_ext_lookup_low(): New functions.
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.
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.
