Bug#12407753: Time to compare a row is missing in cost calculation of semi-join
Stage 3: Fix the bug(s)
What has been done:
- Adjusted costs for handling temporary tables based on benchmarks.
- Added cost of evaluating a row for all semi-join strategies.
- Semi-join FirstMatch: Intermediate cost calculation assumed join
buffering was always possible, final cost calculation assumed that
join buffering could never be used. The truth: Join buffering can be
used if semi-join nest contains only one table.
- Semi-join LooseScan: Intermediate cost calculation assumed join
buffering was possible for outer tables (correct), final cost
calculation assumed that join buffering could never be used.
Join buffering for outer tables has been enabled.
- Semi-join MaterializeLookup: Join buffering was calculated into
the cost for materialization, but later turned off.
Join buffering for this strategy has been enabled.
- Semi-join MaterializeScan: Join buffering was calculated into
the cost for materialization, but later turned off.
Join buffering for this strategy has been enabled.
Made sure that join buffering for semi-join materialization
is not linked with an immediately following join buffer.
- Semi-join DuplicateWeedout: Prefix cost was erroneously picked from
positions[first_tab] instead of positions[first_tab-1].
See also bug#11757320.
- Prefix cost was sometimes picked erroneously, when the previous
table combination was also a semi-join.
mysql-test/r/derived.result
Recorded new result file.
mysql-test/r/group_by.result
Semi-join strategy changed from FirstMatch to Materialize.
Occurs because materialization strategy has fewer compares than FM.

Handler calls are reduced with new plan.

mysql-test/t/derived.test
Plan changed, needed to force use of DuplicateWeedout
sql/sql_const.h
Adjusted cost factors for creation of temporary tables based on
actual benchmarks.
Adjusted costs for temporary table row operations based on benchmark.
Actually, lookup and write operations are equally costly.
sql/sql_select.cc
optimize_semijoin_nests(): Added cost for creation of temporary table.
Adjusted size of materialized table because of duplicate elimination.
get_best_combination(): Set JOIN_TAB reference in best_positions
to NULL when creating final JOIN_TAB array. Forgotten refactoring.
setup_join_buffering(): Sets up join buffering based on corrected
decisions for all semi-join strategies. Prevent linking with previous
join cache when previous operation is Materialization.
semijoin_fm_ls_access_paths() will now calculate new access paths
and cost for FirstMatch and LooseScan semi-join strategies,
based on corrected join buffering choices. ROW_EVALUATE_COST
is added to the cost calculation.
semijoin_mat_scan_access_paths(): ROW_EVALUATE_COST is added to
the cost calculation.
semijoin_dupsweedout_access_paths(): ROW_EVALUATE_COST is added to
the cost calculation.
Prefix cost is adjusted, see bug#11757320.
advance_sj_state(): Best semi-join cost is written back to
prefix_cost and prefix_record_count. These are actually the same
values as the output arguments current_cost and current_rowcount,
only with a different representation.
They must be adjusted because they are needed when looking for
prefix cost inside the semijoin_*_access_paths() functions.

Bug#13261277: Unchecked key length caused missing records.
When a key for derived table is created it wasn't checked that key length is
below tmp table engine's maximum supported key length. Too long key caused
wrong key generated when switching from heap to myisam. This led to
missing rows and errors when storing rows in tmp table.
Now TABLE::add_tmp_key checks if the key length is below allowed limit and
ignores the key otherwise.
@ mysql-test/r/derived.result
Added a test case for the bug#13261277.
@ mysql-test/t/derived.test
