When checking for applicability of join cache
we must disable its usage only if there is no
temp table in use.
When a temp table is used we can use join
cache (and it will not make the result-set
unordered) to fill the temp table. The filesort()
operation is then applied to the data in the temp
table and hence is not affected by join cache
usage.
Fixed by narrowing the condition for disabling
join cache to exclude the case where temp table
is used.

Non-correlated scalar subqueries may get executed
in EXPLAIN at the optimization phase if they are
part of a right hand sargable expression.
If the scalar subquery uses a temp table to
materialize its results it will replace the
subquery structure from the parser with a simple
select from the materialization table.
As a result the EXPLAIN will crash as the
temporary materialization table is not to be shown
in EXPLAIN at all.
Fixed by preserving the original query structure
right after calling optimize() for scalar subqueries
with temp tables executed during EXPLAIN.

some rollup rows (rows with NULLs for grouping attributes) if GROUP BY
list contained constant expressions.
This happened because the results of constant expressions were not put
in the temporary table used for duplicate elimination. In fact a constant
item from the GROUP BY list of a ROLLUP query can be replaced for an
Item_null_result object when a rollup row is produced .
Now the JOIN::rollup_init function wraps any constant item referenced in
the GROYP BY list of a ROLLUP query into an Item_func object of a special
class that is never detected as constant item. This ensures creation of
fields for such constant items in temporary tables and guarantees right
results when the result of the rollup operation first has to be written
into a temporary table, e.g. in the cases when duplicate elimination is
required.

Itroduced class Item_func_rollup_const derived from Item_func. The object of
this class are never detected as constant items.
We use them for wrapping constant items from the GROUP BY list of any ROLLUP
query. This wrapping allows us to ensure writing constant items into temporary
tables whenever the result of the ROLLUP operation has to be written into a
temporary table, e.g. when ROLLUP is used together with DISTINCT in the SELECT
list.

DATE and DATETIME can be compared either as strings or as int. Both
methods have their disadvantages. Strings can contain valid DATETIME value
but have insignificant zeros omitted thus became non-comparable with
other DATETIME strings. The comparison as int usually will require conversion
from the string representation and the automatic conversion in most cases is
carried out in a wrong way thus producing wrong comparison result. Another
problem occurs when one tries to compare DATE field with a DATETIME constant.
The constant is converted to DATE losing its precision i.e. losing time part.
This fix addresses the problems described above by adding a special
DATE/DATETIME comparator. The comparator correctly converts DATE/DATETIME
string values to int when it's necessary, adds zero time part (00:00:00)
to DATE values to compare them correctly to DATETIME values. Due to correct
conversion malformed DATETIME string values are correctly compared to other
DATE/DATETIME values.
As of this patch a DATE value equals to DATETIME value with zero time part.
For example '2001-01-01' equals to '2001-01-01 00:00:00'.
The compare_datetime() function is added to the Arg_comparator class.
It implements the correct comparator for DATE/DATETIME values.
Two supplementary functions called get_date_from_str() and get_datetime_value()
are added. The first one extracts DATE/DATETIME value from a string and the
second one retrieves the correct DATE/DATETIME value from an item.
The new Arg_comparator::can_compare_as_dates() function is added and used
to check whether two given items can be compared by the compare_datetime()
comparator.
Two caching variables were added to the Arg_comparator class to speedup the
DATE/DATETIME comparison.
One more store() method was added to the Item_cache_int class to cache int
values.
The new is_datetime() function was added to the Item class. It indicates
whether the item returns a DATE/DATETIME value.

This bug was intruduced by the fix for bug#17212 (in 4.1). It is not
ok to call test_if_skip_sort_order since this function will
alter the execution plan. By contract it is not ok to call
test_if_skip_sort_order in this context.
This bug appears only in the case when the optimizer has chosen
an index for accessing a particular table but finds a covering
index that enables it to skip ORDER BY. This happens in
test_if_skip_sort_order.
mysql-test/r/key.result:
Bug#24778
test case.
The bug causes the result to be the empty set.
mysql-test/t/key.test:
Bug#24778
The minimal test case that reveals the bug. The reason for such a
complicated schema is that we have to convince the optimizer to
pick one index, then discard it in order to be able to skip
ORDER BY.
sql/sql_select.cc:
bug#24778
Removed the call to test_if_skip_sort_order that constituted the
bug.

Short overview:
Changed a lot of variable, functions, defines and struct elements to use more readable names
More comments (mostly function and structure slot comments)
Other things:
Changed 'USE_WHOLE_KEY' to a big number to not interfer with long keys
Ensure that tail block are at least of size 'MIN_TAIL_SIZE'
Allow longer keys and key parts than before (don't limit Maria interface by HA_MAX_KEY_LENGTH)
Use ma_chsize() to write initial bitmap page
Added checking if using file with wrong block_size
Added issing types to type_names[] (for maria_chk -d)
Added maria_max_key_length()
include/maria.h:
Changed maria_portable_size_char_ptr to portable_size_char_ptr and moved it to my_handler.h
Removed not used variable maria_delay_rec_write.
More comments
include/my_handler.h:
Added portable_sizeof_char_ptr
include/myisam.h:
Changed mi_portable_size_char_ptr to portable_size_char_ptr and moved it to my_handler.h
mysql-test/r/maria.result:
Fix results when we now have a longer key length
mysql-test/t/maria.test:
More tests
mysys/my_pread.c:
Code cleanup
sql/net_serv.cc:
Changed warning to note (as in main 5.1 tree) to avoid not critical failing tests
sql/sql_select.cc:
Use portable_sizeof_char_ptr
storage/maria/ha_maria.cc:
Added max_supported_key_length(), as this is not a trival function anymore
storage/maria/ha_maria.h:
Moved max_supported_key_length(), as this is not a trival function anymore
storage/maria/ma_bitmap.c:
Lots of new comments
Added maria_bitmap_marker[] to mark 2 last bytes of each bitmap (for corruption detection)
Trivial code changes (based on review comments)
storage/maria/ma_blockrec.c:
More code comments
Renamed _block_row() functions to _block_record()
Trivial code changes, based on review comments
Moved Code from maria_close() to _ma_end_block_record()
Some function renames to make things more understandable
DIR_ENTRY_OFFSET -> DIR_COUNT_OFFSET
keybuff_used -> keyread_buff_used
ma_recordpos_to_offset -> ma_recordpos_to_dir_entry
Changed some 'rec' named variables to 'column'.
Ensure that tail block are at least of size 'MIN_TAIL_SIZE'
storage/maria/ma_blockrec.h:
More comments
DIRCOUNT_SIZE -> DIR_COUNT_SIZE
Added define for maira_bitmap_marker[]
ma_recordpos_to_offset -> ma_recordpos_to_dir_entry
xxx_block_row() -> xxx_block_record()
Made _ma_read_bitmap_page() static
storage/maria/ma_check.c:
More comments
ma_recordpos_to_offset() -> ma_recordpos_to_dir_entry()
DIR_ENTRY_OFFSET -> DIR_COUNT_OFFSET
rec variables -> column variables
recdef -> columndef
storage/maria/ma_checksum.c:
rec -> column
Avoid an 'if' in _ma_checksum() for the common case
storage/maria/ma_close.c:
Moved resetting of info->dfile to ma_end_once_block_record()
storage/maria/ma_create.c:
Some variable changes to make things more readable:
recinfo -> columndef
rec -> column
rec_end -> end_column
record_type -> datafile_type
ma_recinfo_write() -> ma_columndef_write()
Fixed wrong setting of 'data_file_length'; Now max_rows should be calculated correctly
New check if too long key.
Use ma_chsize() to write bitmap page.
storage/maria/ma_delete.c:
keybuff_used -> keyread_buff_used
