Bug fix inspired by: Moritz Mertinkat
Add some extra error output and code cleanup in an attempt to fix/debug
a rare random testsuite problem in check_warnings, where the exit code
from mysqltest is somehow corrupted inside mysql-test-run.pl.
include/my_global.h:
Fix compiler warnings on some platforms.
mysql-test/lib/My/SafeProcess.pm:
Move dereference of $? subprocess exit code closer to where it is generated,
to make the code more robust and on the chance that this will fix the
occasional problems in check_warnings we see in Buildbot.
mysql-test/mysql-test-run.pl:
When check_warnings failed, also log the mysqld server for which it failed.
sql/sql_lex.cc:
Fix compiler warning about possibly uninitialised value, by rewriting a for()
loop that is always executed at least once into a do .. while() loop with an
assert.
sql/table.cc:

storage/federatedx/ha_federatedx.cc:

storage/myisam/ft_stopwords.c:

storage/myisam/mi_write.c:

loop that is always executed at least once into a do .. while() loop with an
assert.

- Adjust timing in test case, to avoid test failures caused by high load
on machines and consequent race conditions in the test case.
- Add another variant of Valgrind suppressions for memory leak in system
libraries when unloading dynamic object files.
mysql-test/r/information_schema.result:
Adjust timing to avoid test failures due to races.
mysql-test/t/information_schema.test:
Adjust timing to avoid test failures due to races.
mysql-test/valgrind.supp:
Add another variant of valgrind suppression for leak in system libs.
query:
- When subquery is located in ORDER BY, EXPLAIN will run as follows:
select_describe() will run JOIN::prepare()/optimize() for the subquery;
then at some point subselect_single_select_engine::prepare() will be called,
which will create another join and run join->prepare().
In mainline mysql this is not a problem because subquery's join will be
destroyed after the first call.
In MariaDB, it won't (table elimination needs to keep JOIN objects around
for longer in order to know which tables were eliminated when constructing
EXPLAIN EXTENDED warning).
Fix the problem of memory leak by calling select_lex->cleanup() in
subselect_single_select_engine::prepare().
tmp_table_size can now be set to 0 (to disable in memory internal temp tables)
Improved speed for internal Maria temp tables:
- Don't use packed keys, except with long text fields.
- Don't copy key all accessed pages during key search.
Some new benchmark tests to sql-bench (for group by)
BUILD/compile-pentium64-gcov:
Update script to use same pentium_config flags as other tests
BUILD/compile-pentium64-gprof:
Update script to use same pentium_config flags as other tests
include/my_sys.h:
Added count of my_sync calls
mysql-test/r/variables.result:
tmp_table_size can now be set to 0
sql-bench/test-select.sh:
Added some new test for GROUP BY on a not key field and group by with different order by
sql/mysqld.cc:
Added count of my_sync calls
tmp_table_size can now be set to 0 (to disable in memory internal temp tables)
sql/sql_select.cc:
If tmp_table_size is 0, don't use in memory temp tables (good for benchmarking MyISAM/Maria temp tables)
Don't pack keys for Maria tables; The 8K page size makes packed keys too slow for temp tables.
storage/maria/ma_key_recover.h:
Moved definition to maria_def.h
storage/maria/ma_page.c:
Moved code used to simplify comparing of identical Maria tables to own function (page_cleanup())
Fixed that one can read a page with a read lock.
storage/maria/ma_rkey.c:
For not exact key reads, cache the page where we found key (to speed up future read-next/read-prev calls)
storage/maria/ma_search.c:
Moved code to cache last key page to separate function.
Instead of copying pages, only get a link to the page. This notable speeds up key searches on bigger tables.
storage/maria/ma_write.c:
Added comment
storage/maria/maria_def.h:
Moved page_cleanup() to separate function.
Bug#46949: memory leak with failed alter table to create partitions based on extract()
Bug#51830: Incorrect partition pruning on range partition (regression)
Fixed valgrind failure in select_describe(), read of uninitialized
Item_subselect::eliminated.
PBXT test file updates to reflect changes done in MySQL.
mysql-test/suite/pbxt/r/partition_error.result:
Result file update following MySQL 5.1.44 changes.
mysql-test/suite/pbxt/r/partition_pruning.result:
Result file update following MySQL 5.1.44 changes.
mysql-test/suite/pbxt/t/partition_error.test:
Test file update following MySQL 5.1.44 changes.
sql/item_subselect.cc:
Fixed valgrind failure in select_describe(), read of uninitialized
Item_subselect::eliminated:
- it turns out we can call select_describe() without having fixed
subquery items for child subselects. These are not the kind of subqueries
that we could eliminate, so the fix is to ensure that
item_subselect->eliminated==FALSE even before fix_fields is called.
Also added code to reset item_subselect->eliminated back to FALSE in
Item::reset() call.
sql/item_subselect.h:
Fixed valgrind failure in select_describe(), read of uninitialized
Item_subselect::eliminated:
- it turns out we can call select_describe() without having fixed
subquery items for child subselects. These are not the kind of subqueries
that we could eliminate, so the fix is to ensure that
item_subselect->eliminated==FALSE even before fix_fields is called.
Also added code to reset item_subselect->eliminated back to FALSE in
Item::reset() call.
sql/sql_partition.cc:
Fix Bug#51830: Revert part of the patch for Bug#49742, which caused the regression.
sql/table.cc:
Fix Bug#46949: memory leak in failed ALTER TABLE with partitioning.
Save no-records constant tables in JOIN::const_table_map before we invoke
eliminate_tables(). Failure to do so caused crash when the same table was
marked as constant two times
mysql-test/r/table_elim.result:
LPBUG#524025 Running RQG outer_join test leads to crash

sql/sql_select.cc:
LPBUG#524025 Running RQG outer_join test leads to crash
Save no-records constant tables in JOIN::const_table_map before we invoke eliminate_tables(). Failure to do so caused crash when the same table was marked as constant two times.
- Avoid full inline of mark_trx_read_write() for many functions
- Avoid somewhat expensive tests for every write/update/delete row
sql/handler.h:
Adde ha_start_of_new_statement() to reset internal variables as part of the code in "open_table" that resets TABLE object for the new statement
Faster mark_trx_read_write_part()
sql/sql_base.cc:
Don't manipulate table->file internal structs directly
sql/sql_class.cc:
reset userstat_running after the data were colleced to prevent double accounting.
don't assert for COM_QUERY, many more are possible.
don't update_stats() here, it's too late, lex->sql_command may be already reset
sql/sql_parse.cc:
update_stats() here, when the current arena is still valid
- When analying multiple equalities, take into account that they
may not have a single table field that belongs to one of the tables
that we're trying to eliminate (and they are not useful for table
elimination in that case)

LPBUG#523593: Running RQG optimizer_no_subquery crashes MariaDB
