-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.
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.
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.
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.
of breaking serializability. (Bug #3300)
ha_innobase::unlock_row(): reset the "did semi consistent read" flag
ha_innobase::was_semi_consistent_read(),
ha_innobase::try_semi_consistent_read(): new methods
row_prebuilt_t, row_create_prebuilt(): add field row_read_type for
keeping track of semi-consistent reads
row_vers_build_for_semi_consistent_read(),
row_sel_build_committed_vers_for_mysql(): new functions
row_search_for_mysql(): implement semi-consistent reads
Mostly fix bug #13778, when FOREIGN_KEY_CHECKS=0 we still need to check
that datatypes between foreign key references are compatible.
Add test cases (also for bug #9802).
