This essentially reverts commit 4e89ec6692
and only disables InnoDB persistent statistics for tests where it is
desirable. By design, InnoDB persistent statistics will not be updated
except by ANALYZE TABLE or by STATS_AUTO_RECALC.
The internal transactions that update persistent InnoDB statistics
in background tasks (with innodb_stats_auto_recalc=ON) may cause
nondeterministic query plans or interfere with some tests that deal
with other InnoDB internals, such as the purge of transaction history.
row_drop_table_for_mysql(): If a #sql2 table is open in another
thread (purge) while we attempting to drop it, rename it to #sql-ib
name to hide it from the SQL layer.
Adjust tests accordingly to hide #sql-ib tables, which can
continue to exist until the background DROP TABLE completes.
Currently InnoDB uses internal parser for adding foreign keys. Remove
internal parser and use data parsed by SQL parser (sql_yacc) for
adding foreign keys.
- create_table_info_t::create_foreign_keys() replacement for
dict_create_foreign_constraints_low();
- Pass constraint name via Foreign_key object.
Temporary until MDEV-20865:
- Pass alter_info as part of create_info.
fkerr_t: Errors for the foreign key checks. Replaces ulint,
which used #define that looked like dberr_t literals.
wsrep_dict_foreign_find_index(): Remove. Use
dict_foreign_find_index() instead, with default parameters.
dict_foreign_push_index_error(): Do not add redundant quotes
around quoted table names.
Some test are still disabled as they provide different results,
fail on different error or crash.
Fixes also MDEV-14060 InnoDB: Foreign key constraint to
geometry type does not work where test intentionally tried
incorrect cases.
