Pass THD to find_all_keys() and Item_equal::Item_equal().
In MRR use table->in_use instead of current_thd.
This reduces number of pthread_getspecific() calls from 354 to 320.
(Backport to 5.3)
(variant #2, with fixed coding style)
- Make Mrr_ordered_index_reader::resume_read() restore index position
only if it was saved before with Mrr_ordered_index_reader::interrupt_read().
- Key_value_records_iterator::get_next() should pass pointer to the key
to handler->ha_index_next_same(). Because of a typo bug, pointer-to-pointer
was passed instead in certain cases.
This is port of fix for MySQL BUG#17647863.

message:
Bug#17647863: MYSQL DOES NOT COMPILE ON OSX 10.9 GM
Rename test() macro to MY_TEST() to avoid conflict with libc++.
- The crash was caused because the optimizer called handler->multi_range_read_info()
on a derived temporary table. That table has been created, but not opened yet.
Because of that, handler::table was NULL, which caused crash.
Fixed by changing DS-MRR methods to use handler::table_share instead.
handler::table_share is set in handler ctor, so this should be safe.
includes:
* remove some remnants of "Bug#14521864: MYSQL 5.1 TO 5.5 BUGS PARTITIONING"
* introduce LOCK_share, now LOCK_ha_data is strictly for engines
* rea_create_table() always creates .par file (even in "frm-only" mode)
* fix a 5.6 bug, temp file leak on dummy ALTER TABLE
-Added test and extra code to ensure we don't leave keyread on for a handler table.
-Create on disk temporary files always with long data pointers if SQL_SMALL_RESULT is not used. This ensures that we can handle temporary files bigger than 4G.
mysql-test/include/default_mysqld.cnf:
Run test suite with smaller aria keybuffer size
mysql-test/suite/maria/maria3.result:
Run test suite with smaller aria keybuffer size
mysql-test/suite/sys_vars/r/aria_pagecache_buffer_size_basic.result:
Run test suite with smaller aria keybuffer size
sql/handler.cc:
Disable key read (extra safety if something went wrong)
sql/multi_range_read.cc:
Ensure we have don't leave keyread on for secondary_file
sql/opt_range.cc:
Simplify code with mark_columns_used_by_index_no_reset()
Ensure that read_keys_and_merge() disableds keyread if it enables it
sql/opt_subselect.cc:
Remove not anymore used argument for create_internal_tmp_table()
sql/sql_derived.cc:
Remove not anymore used argument for create_internal_tmp_table()
sql/sql_select.cc:
Use 'enable_keyread()' instead of calling HA_EXTRA_RESET. (Makes debugging easier)

Remove not anymore used argument for create_internal_tmp_table()
More DBUG
sql/sql_select.h:
Remove not anymore used argument for create_internal_tmp_table()
Solaris fixes:
- Fixed that wait_timeout_func and wait_timeout tests works on solaris
- We have to compile without NO_ALARM on Solaris as Solaris doesn't support timeouts on sockets with setsockopt(.. SO_RCVTIMEO).
- Fixed that compile-solaris-amd64-debug works (before that we got a wrong ELF class: ELFCLASS64 on linkage)
- Added missing sync_with_master
Other bug fixes:
- Free memory for rpl_global_gtid_binlog_state before exit() to avoid 'accessing uninitalized mutex' error.
BUILD/FINISH.sh:
Fixed issues on Solaris with ksh
BUILD/compile-solaris-amd64-debug:
Added missing -m64 flag
configure.cmake:
We have to compile without NO_ALARM on Solaris as Solaris doesn't support timeouts on sockets with setsockopt(.. SO_RCVTIMEO)
mysql-test/suite/rpl/t/rpl_gtid_mdev4473.test:
- Added missing sync_with_master (fix by knielsen)
sql-common/client.c:
Added () to get rid of compiler warning
sql/item_strfunc.cc:
Fixed compiler warning
sql/log.cc:
Free memory for static variable rpl_global_gtid_binlog_state before exit()
- If we are compiling with safemalloc, we would try to call sf_free() for some members after sf_terminate() was called, which would result of trying to access the uninitalized mutex 'sf_mutex'
sql/multi_range_read.cc:
Fixed compiler warnings of converting double to ulong.
sql/opt_range.cc:
Fixed compiler warnings of converting double to ulong or uint
- Better to have all variables that can be number of rows as 'ha_rows'
sql/rpl_gtid.cc:
Added rpl_binlog_state::free() to be able to free memory for static objects before exit()
sql/rpl_gtid.h:
Added rpl_binlog_state::free() to be able to free memory for static objects before exit()
sql/set_var.cc:
Fixed compiler warning
sql/sql_join_cache.cc:
Fixed compiler warnings of converting double to uint
sql/sql_show.cc:
Added cast to get rid of compiler warning
sql/sql_statistics.cc:
Remove code that didn't do anything.
(store_record() with record[0] is a no-op)
storage/xtradb/os/os0file.c:
Added __attribute__ ((unused))
support-files/compiler_warnings.supp:
Ignore warnings from atomic_add_64_nv
(was not able to fix this with a cast as the macro is a bit different between systems)
vio/viosocket.c:
Added more DBUG_PRINT
that introduced engine independent persistent statistics.
In particular:
- added an enumeration type for possible values of the system
variable use_stat_tables
- renamed KEY::real_rec_per_key to KEY::actual_rec_per_key
- optimized the collection of statistical data for any primary
key defined only on one column.
sql/sql_insert.cc:
CREATE ... IF NOT EXISTS may do nothing, but
it is still not a failure. don't forget to my_ok it.
******
CREATE ... IF NOT EXISTS may do nothing, but

sql/sql_table.cc:
small cleanup

small cleanup
- Mrr_ordered_index_reader::interrupt_read() and resume_read() should
save/restore not just index lookup tuple, but entire index tuple.
Key parts that are not used for index lookup can be still used in
pushed index condition. Failure to save/restore will cause the index
condition to be evaluated over the wrong values.
Split status variable Rows_read to Rows_read and Rows_tmp_read so that one can see how much real data is read.
Same was done with with Handler_update and Handler_write.
Fixed bug in MEMORY tables where some variables was counted twice.
Added new internal handler call 'ha_close()' to have one place to gather statistics.
Fixed bug where thd->open_options was set to wrong value when doing admin_recreate_table()
mysql-test/r/status.result:
Updated test results and added new tests
mysql-test/r/status_user.result:
Udated test results
mysql-test/t/status.test:
Added new test for temporary table status variables
sql/ha_partition.cc:
Changed to call ha_close() instead of close()
sql/handler.cc:
Added internal_tmp_table variable for easy checking of temporary tables.
Added new internal handler call 'ha_close()' to have one place to gather statistics.
Gather statistics for internal temporary tables.
sql/handler.h:
Added handler variables internal_tmp_table, rows_tmp_read.
Split function update_index_statistics() to two.
Added ha_update_tmp_row() for faster tmp table handling with more statistics.
sql/item_sum.cc:
ha_write_row() -> ha_write_tmp_row()
sql/multi_range_read.cc:
close() -> ha_close()
sql/mysqld.cc:
New status variables: Rows_tmp_read, Handler_tmp_update and Handler_tmp_write
sql/opt_range.cc:
close() -> ha_close()
sql/sql_base.cc:
close() -> ha_close()
sql/sql_class.cc:
Added handling of rows_tmp_read
sql/sql_class.h:
Added new satistics variables.
rows_read++ -> update_rows_read() to be able to correctly count reads to internal temp tables.
Added handler::ha_update_tmp_row()
sql/sql_connect.cc:
Added comment
sql/sql_expression_cache.cc:
ha_write_row() -> ha_write_tmp_row()
sql/sql_select.cc:
close() -> ha_close()
ha_update_row() -> ha_update_tmp_row()
sql/sql_show.cc:
ha_write_row() -> ha_write_tmp_row()

ha_write_row() -> ha_write_tmp_row()

ha_write_row() -> ha_write_tmp_row()
sql/table.cc:
close() -> ha_close()
storage/heap/ha_heap.cc:
Removed double counting of statistic variables.
close -> ha_close() to get tmp table statistics.
storage/maria/ha_maria.cc:
close -> ha_close() to get tmp table statistics.
