-Change default mode of SELECT from "lock in share mode" to "consistent
read".
-Remove support from SELECT for specifying "consistent read".
-Add support in SELECT for specifying "lock in share mode".
-Change all uses of SQL parser to specify "lock in share mode".
ut_print_name(), ut_print_namel(): Add parameter table_id for distinguishing
names of tables from other identifiers (names of indexes, columns and
constraints).
innobase_convert_from_table_id(), innobase_convert_from_id(),
innobase_convert_from_filename(), innobase_get_charset(): New functions.
dict_accept(), dict_scan_id(), dict_scan_col(), dict_scan_table_name(),
dict_skip_word(), dict_create_foreign_constraints_low():
Add parameter "cs", so that isspace() can be replaced with my_isspace(),
whose operation depends on the connection character set.
dict_scan_id(): Convert the identifier to UTF-8.
dict_str_starts_with_keyword(): New extern function, to replace dict_accept()
in row_search_for_mysql().
mysql_get_identifier_quote_char(): Replaced with innobase_print_identifier().
ha_innobase::create(): Remove the thd->convert_string() call.
Pass the statement to InnoDB in the connection character set
and let InnoDB convert the identifiers to UTF-8.
the code is compiled with GCC 3 or later on other platforms than
Windows or Netware. Also disable the variable ut_dbg_stop_threads
and the function ut_dbg_stop_thread() in this case, unless
UNIV_SYNC_DEBUG is defined. This should allow the compiler to
generate more compact code for assertions.
FIL_PAGE_NEXT and FIL_PAGE_PREV when accessing sibling pages
of B-tree indexes.
btr_validate_level(): Check the validity of the doubly linked list
formed by FIL_PAGE_NEXT and FIL_PAGE_PREV.
#ifdef UNIV_IBUF_DEBUG. Previously, when compiled without UNIV_IBUF_DEBUG,
invoking ibuf_count_get() would crash InnoDB. The function is only being
called #ifdef UNIV_IBUF_DEBUG.
Remove unused dict_table_LRU_trim().
Remove unused 'trx' parameter from the functions dict_table_get_on_id_low,
dict_table_get and dict_table_get_and_increment_handle_count.
DB_ROW_ID", by refusing tables that use reserved column names.
Add dict_mem_table_free(), use it instead of duplicating the code everywhere.
Use already existing dict_mem_index_free().
Fix memory leaks in row_create_table_for_mysql() in rare corner cases.
the implementation would be challenging with ROW_FORMAT=COMPACT.
Remove the table types DICT_TABLE_CLUSTER_MEMBER and DICT_TABLE_CLUSTER and
all related tests and functions.
dict_table_t: Remove mix_id, mix_len, mix_id_len, mix_id_buf, and
cluster_name.
plan_t: Remove mixed_index.
dict_create_sys_tables_tuple(): Set MIX_ID=0, MIX_LEN=0 and CLUSTER_NAME=NULL
when inserting into SYS_TABLES.
dict_tree_check_search_tuple(): Enclose in #ifdef UNIV_DEBUG.
returns in the query graph execution stage, we can't free pars_info_t in
pars_sql(). Instead, make pars_sql() transfer ownership of pars_info_t to
the created query graph, and make que_graph_free() free it if needed.
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.
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
