This makes the keys smaller (no row pointer) and gives us proper errors if we
use the table wrongly.
sql/sql_select.cc:
Use NO_RECORD for tables that doesn't need row data.
storage/maria/Makefile.am:
Added ma_norec.c
storage/maria/ma_check.c:
Added support for NO_RECORD record format (don't store any row data)
storage/maria/ma_norec.c:
Added support for NO_RECORD record format
storage/maria/ma_open.c:
Added support for NO_RECORD record format
storage/maria/ma_search.c:
Added support for 0 size row pointers (used with NO_RECORD)
storage/maria/ma_test1.c:
Added testing of NO_RECORD record format.
storage/maria/maria_chk.c:
Added support for NO_RECORD
storage/maria/maria_def.h:
Added support for NO_RECORD
storage/maria/unittest/ma_test_all-t:
Added testing of NO_RECORD record format
temptables, not "uniques", that are hash-based keys.
sql/sql_expression_cache.cc:
Don't set uniques (we don't want or need an unique
constraint on this table)
This was needed as the old code caused us to have LOTS of duplicate
hash values when used by optimizer.
include/m_ctype.h:
Made my_hash_sort_bin() exernal
storage/maria/ma_unique.c:
Better hash for packed numeric data for unique handling.
This was needed as the old code caused us to have LOTS
of duplicate hash values when used by optimizer.
mysql-test/suite/handler/heap.result:
New test case
mysql-test/suite/handler/heap.test:
New test case
sql/sql_handler.cc:
If we get a fatal error in handler read, end table/index scan as it's likely it was wrongly used (for example not supported feature for index)
Made sure that the optimal fields are used by TABLE_REF objects
when building index access keys to joined tables.
Fixed a bug in the template function that sorts the elements of
a list using the bubble sort algorithm. The bug caused poor
performance of the function. Also added an optimization that
skips comparison with the most heavy elements that has been
already properly placed in the list.
Made the comparison of the fields belonging to the same Item_equal
more granular: fields belonging to the same table are also ordered
according to some rules.
An assertion failure was triggered for a 6-way join query that used two
join buffers.
The failure happened because every call of JOIN_CACHE::join_matching_records
saved and restored status of all tables that were accessed before the table
join_tab. It must do it only for those of them that follow the last table
using a join buffer.

Bug#52068: Optimizer generates invalid semijoin materialization plan
When MaterializeScan semijoin strategy was used and there were one
or more outer dependent tables before the semijoin tables, the scan
over the materialized table was not properly reset for each row of
the prefix outer tables.
Example: suppose we have a join order:
ot1 SJ-Mat-Scan(it2 it3) ot4
Notice that this is called a MaterializeScan, even though there is an
outer table ahead of the materialized tables. Usually a MaterializeScan
has the outer tables after the materialized table, but this is
a special (but legal) case with outer dependent tables both before and
after the materialized table.
For each qualifying row from ot1, a new scan over the materialized
table must be set up. The code failed to do that, so all scans after
the first one returned zero rows from the materialized table.
Changed handler.inc to make test row order independent
mysql-test/r/table_elim.result:
Updated test results for 5.3
mysql-test/suite/handler/aria.result:
Updated result
mysql-test/suite/handler/handler.inc:

Added test case
sql/handler.h:
Move setting/resetting of active_index to ha_index_init()/ha_index_end() to simplify handler functions index_init()/index_end()
Fixed that get_index() returns MAX_KEY if index is not inited (this fixed LP#697610)
storage/federated/ha_federated.cc:
Settting of active_index is not needed anymore
storage/maria/ma_pagecache.c:
Added error message if we have too little memory for Maria page cache
- Cause: handler::in_range_check_pushed_down was not reset when a
command would call handler->idx_cond_push() without later calling
handler->index_end().
- Fix: reset the variable in handler->reset(), too (like we do with other
Index Condition Pushdown members).
storage/maria/ma_pagecache.c:
- Ensure that we write also the last buffer in flush if buffer overflows.
- Don't set PCBLOCK_IN_FLUSH if we don't flush the page
- Added some new safety asserts.
Don't allow too low value of pagecache_buffer_size for mysqld
storage/maria/ha_maria.cc:
Don't allow too low value of pagecache_buffer_size (as it will stop mysqld from starting)
storage/maria/maria_read_log.c:
Allow one to decrease page-buffer-size down to 1M (from 128M)
Added key and file version numbers to MEMORY tables so that we can detect if someone has changed them between HANDLER calls.

Abort table scan if table has been recreated.
storage/heap/ha_heap.h:
Added support for HANDLER
storage/heap/hp_clear.c:
Increase version number so that we can notice changes if using HANDLER
storage/heap/hp_delete.c:
Increase key data version number on key changes.

Remember version of key data
Give error if using read-first on hash key.
storage/heap/hp_rkey.c:
Remember version of key data
storage/heap/hp_rlast.c:
Remember version of key data
Give error if using read-last on hash key.

storage/maria/ma_search.c:
Fixed test to avoid compiler warnings.
Safety fix to ensure that my_error is properly set in case of errors.
- Fix for MySQL BUG#52357 added NESTED_JOIN::is_fully_covered() which would
not take into account that MariaDB's table elimination could eliminate tables
from join plan (and so, from join nest).
Fixed the check in the function to compare post-table-elimination numbers.
- Set lastinx= ~0 when last_key.keyinfo is set.
storage/maria/ma_check.c:
Set lastinx= ~0 when last_key.keyinfo is set
storage/maria/ma_ft_boolean_search.c:
Set lastinx= ~0 when last_key.keyinfo is set
