weakens the locks for this session similarly like the option
innodb_locks_unsafe_for_binlog. This patch removes almost all
gap locking (used in next-key locking) and makes MySQL to release
the row locks on the rows which does not belong to result set.
Additionally, nonlocking selects on INSERT INTO SELECT,
UPDATE ... (SELECT ...), and CREATE ... SELECT ... use a
nonlocking consistent read. If a binlog is used, then binlog
format should be set to row based binloging to make the execution
of the complex SQL statements.
duplicate http://bugs.mysql.com/bug.php?id=17134 : MySQL's partitioned
table code does not set prebuilt->sql_stat_start right if it does an
insert in the same statement after doing a search first in the same
partition table. We now write trx id always to the buffer, not just when
flag sql_stat_start is on. This will waste CPU time very slightly.
a duplicate record to a clustered index comprising
more than about 90 columns. (Bug #18384)
row_ins_duplicate_error_in_clust(): Call mem_heap_free(heap) at func_exit
if needed.
r340: Fix http://bugs.mysql.com/bug.php?id=18283 in ha_innodb.cc and
http://bugs.mysql.com/bug.php?id=18238 in InnoDB
r339: Remove disk space leak on update of BLOB columns (Bug #18252).
btr_cur_pessimistic_update(): Invoke rec_get_offsets() after
rec_set_field_extern_bits().
btr_store_big_rec_extern_fields(): Note that offsets will no longer be
valid after calling this function.
r338: Fix bug 18238 : check in pessimistic insert and update if the buffer
pool is exhausted by locks
Remove UNIV_RELEASE_NOT_YET_STABLE and related checks.
page_rec_is_comp(): Remove the bounds check.
row_sel_field_store_in_mysql_format(): Turn the assertions on mbminlen,
mbmaxlen and templ->type into debug assertions.
row_upd_index_replace_new_col_vals_index_pos(): Add a parameter, "ibool
order_only", for limiting the replacement to the ordering fields of the
index. Adjust callers.
In this port, the comment for the parameter was adjusted to make it clear
that it only supports clustered indexes.
probably caching. Fixed test results.
This patch implements a high-granularity read view to be used with
cursors. In this high-granularity consistent read view modifications
done by the creating transaction after the cursor is created or
future transactions are not visible. But those modifications that
transaction did before the cursor was created are visible.
which can contain the new flag DICT_TF_COMPACT. Change dict_mem_table_create
to take a flags argument. Add dict_table_is_comp(). Adapt all users.
Change some places to explicitly assume that system tables do not use the
compact page format.
Corrected some comments.
os_file_create_tmpfile(): Remove the implementation from InnoDB Hot Backup.
In InnoDB Hot Backup builds, do not define dict_casedn_str(),
which is invoked in fil_load_single_table_tablespace() on
Windows. This function depends on innobase_casedn_str() and
my_casedn_str().
Define btr_check_node_ptr() and data_error only #ifdef UNIV_DEBUG.
They are only being used in ut_ad() assertions.
Replace the occurrences of the type uint with ulint, because InnoDB
Hot Backup does not define any uint data type.
Disable lock_validate() in InnoDB Hot Backup builds.
Disable some unused static variables of srv0srv.c in InnoDB Hot Backup builds.
Disable some srv_table_...() functions in InnoDB Hot Backup builds.
Disable some unused static variables in srv0start.c in
InnoDB Hot Backup builds.
Disable io_handler_thread() in InnoDB Hot Backup builds.
Disable srv_calc_low32() and srv_calc_high32() in InnoDB Hot Backup builds
to avoid warnings about unused functions.
In fil_node_open_file(), avoid bogus assertions in InnoDB Hot Backup builds.
In fil_load_single_table_tablespace(), remove the call to dict_casedn_str(),
as it depends on MySQL code.
Copy the code of recv_reset_log_files_for_backup() from InnoDB Hot Backup.
Disable innobase_mysql_cmp(), cmp_whole_field(), cmp_data_data_slow(),
cmp_dtuple_rec_with_match() and cmp_rec_rec_with_match()
in InnoDB Hot Backup builds, as they depend on MySQL code.
Adapt dtype_set_mblen() and dtype_get_fixed_size() for InnoDB Hot Backup
builds, assuming that they will only be called on system tables, which
do not contain multi-byte characters.
Disable the static functions row_ins_set_exclusive_rec_lock() and
row_ins_dupl_error_with_rec() in InnoDB Hot Backup builds
to avoid warnings about unused functions.
In row_sel_field_store_in_mysql_format(), disable some UTF-8 related
assertions #ifndef UNIV_RELEASE_NOT_YET_STABLE.
new tablespaces created from now on.
btr_store_big_rec_extern_fields(): Set FIL_PAGE_TYPE to FIL_PAGE_TYPE_BLOB.
buf_page_print(): Decode FIL_PAGE_TYPE. Replace if-else with switch().
buf_page_create(): Set FIL_PAGE_PREV, FIL_PAGE_NEXT and FIL_PAGE_TYPE.
trx_sysf_create(): Set FIL_PAGE_TYPE to FIL_PAGE_TYPE_TRX_SYS.
Initialize TRX_SYS_RSEG_SPACE.
FIL_PAGE_TYPE: Document that the field cannot be relied on in older
versions of MySQL/InnoDB. Add new type codes.
ibuf_bitmap_page_init(): Document that the rest of the page is uninitialized.
ibuf_add_free_page(): Log the setting of FIL_PAGE_TYPE.
fsp_header_init(): Set FIL_PAGE_TYPE to FIL_PAGE_TYPE_FSP_HDR.
Initialize FSP_NOT_USED.
fsp_fill_free_list(): Set FIL_PAGE_TYPE to FIL_PAGE_TYPE_XDES.
fsp_alloc_seg_inode_page(): Set FIL_PAGE_TYPE to FIL_PAGE_INODE.
fseg_create_general(): Set FIL_PAGE_TYPE to FIL_PAGE_TYPE_SYS.
