INSERT...SELECT reading from an InnoDB table is slow due to
creating explicit record locks. Use the sequence engine instead.
Also, remove the space before rtr_page_need_second_split
to actually make the debug injection work.
In main.index_merge_myisam we remove the test that was added in
commit a2d24def8c because
it duplicates the test case that was added in
commit 5af12e4635.
- multi_range_read_info_const now uses the new records_in_range interface
- Added handler::avg_io_cost()
- Don't calculate avg_io_cost() in get_sweep_read_cost if avg_io_cost is
not 1.0. In this case we trust the avg_io_cost() from the handler.
- Changed test_quick_select to use TIME_FOR_COMPARE instead of
TIME_FOR_COMPARE_IDX to align this with the rest of the code.
- Fixed bug when using test_if_cheaper_ordering where we didn't use
keyread if index was changed
- Fixed a bug where we didn't use index only read when using order-by-index
- Added keyread_time() to HEAP.
The default keyread_time() was optimized for blocks and not suitable for
HEAP. The effect was the HEAP prefered table scans over ranges for btree
indexes.
- Fixed get_sweep_read_cost() for HEAP tables
- Ensure that range and ref have same cost for simple ranges
Added a small cost (MULTI_RANGE_READ_SETUP_COST) to ranges to ensure
we favior ref for range for simple queries.
- Fixed that matching_candidates_in_table() uses same number of records
as the rest of the optimizer
- Added avg_io_cost() to JT_EQ_REF cost. This helps calculate the cost for
HEAP and temporary tables better. A few tests changed because of this.
- heap::read_time() and heap::keyread_time() adjusted to not add +1.
This was to ensure that handler::keyread_time() doesn't give
higher cost for heap tables than for normal tables. One effect of
this is that heap and derived tables stored in heap will prefer
key access as this is now regarded as cheap.
- Changed cost for index read in sql_select.cc to match
multi_range_read_info_const(). All index cost calculation is now
done trough one function.
- 'ref' will now use quick_cost for keys if it exists. This is done
so that for '=' ranges, 'ref' is prefered over 'range'.
- scan_time() now takes avg_io_costs() into account
- get_delayed_table_estimates() uses block_size and avg_io_cost()
- Removed default argument to test_if_order_by_key(); simplifies code
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.
This allows one to run the test suite even if any of the following
options are changed:
- character-set-server
- collation-server
- join-cache-level
- log-basename
- max-allowed-packet
- optimizer-switch
- query-cache-size and query-cache-type
- skip-name-resolve
- table-definition-cache
- table-open-cache
- Some innodb options
etc
Changes:
- Don't print out the value of system variables as one can't depend on
them to being constants.
- Don't set global variables to 'default' as the default may not
be the same as the test was started with if there was an additional
option file. Instead save original value and reset it at end of test.
- Test that depends on the latin1 character set should include
default_charset.inc or set the character set to latin1
- Test that depends on the original optimizer switch, should include
default_optimizer_switch.inc
- Test that depends on the value of a specific system variable should
set it in the test (like optimizer_use_condition_selectivity)
- Split subselect3.test into subselect3.test and subselect3.inc to
make it easier to set and reset system variables.
- Added .opt files for test that required specfic options that could
be changed by external configuration files.
- Fixed result files in rockdsb & tokudb that had not been updated for
a while.
The MDEV-20265 commit e746f451d5
introduces DBUG_ASSERT(right_op == r_tbl) in
st_select_lex::add_cross_joined_table(), and that assertion would
fail in several tests that exercise joins. That commit was skipped
in this merge, and a separate fix of MDEV-20265 will be necessary in 10.4.
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.
row_build_spatial_index_key(): Return early if the column is missing
in the table row tuple.
This is a regression that was introduced by
commit 0e5a4ac253.
The bug was introduced in MariaDB 10.4.0 by
commit 0e5a4ac253
but it is good to have a regression test for this scenario
in all applicable MariaDB versions.
Cover the purge of an undo log record that was written before
the completion of ADD SPATIAL INDEX.
The error message modified.
Then the TABLE_SHARE::error_table_name() implementation taken from 10.3,
to be used as a name of the table in this message.
