Link view/derived table fields to a real table to check turning the table record to null row.
Item_direct_view_ref wrapper now checks if table is turned to null row.
In fill_schema_table_by_open(): free item list before restoring active arena.
sql/sql_show.cc:
Replaced i_s_arena.free_items with DBUG_ASSERT(i_s_arena.free_list == NULL)
(there's nothing to free in that list)

A bug in the lock-free hash implementation!
when lsearch() has not found the key, the caller needs to unpin all the three pins,
because lsearch() was using all the three.
updates to system, statistics and admin tables logged to binary log.
- Removed special code used to temporarily change to statement based replication.
- Changed to a faster and smaller interface for temporarily switching to statement based replication.

Change to new interface to not use row based replication for system table changes.
sql/events.cc:
Change to new interface to not use row based replication for system table changes.
sql/sp.cc:
Removed temporarily switching to statement based replication (this is now done automaticly in mysql_execute_command())
sql/sql_acl.cc:
Change to new interface to not use row based replication for system table changes.
Removed temporarily switching to statement based replication (this is now done automaticly in mysql_execute_command())
sql/sql_class.h:
Added new interface for temporarily switching to statement based replication.
sql/sql_parse.cc:
Mark commands that needs original replication mode with CF_FORCE_ORIGINAL_BINLOG_FORMAT.
Switch automaticly to statement based replication for statements that can't generate row based events (and can't change replication mode)
sql/sql_udf.cc:
Removed temporarily switching to statement based replication (this is now done automaticly in mysql_execute_command())
If a table is already in the table cache but without data from persistent
statistical tables then the function open_and_process_table should not
only allocate memory for this statistical data in the corresponding
TABLE_SHARE object, but also should copy the references to the data into
certain fields of the TABLE data structure: for each key of the table
KEY::read_stats should be copied, and for each column of the table
Field::read_stats should be copied.
Autointersections of an object were treated as nodes, so the wrong result.

test result updated.

small fix to make compilers happy.

Skip intersection points when calculate distance.
THOUGH IT IS NOT.
The following error message is misleading because it claims
that the BLOB space is not counted.
"ERROR 1118 (42000): Row size too large. The maximum row size for
the used table type, not counting BLOBs, is 8126. You have to
change some columns to TEXT or BLOBs"
When the ROW_FORMAT=compact or ROW_FORMAT=REDUNDANT is used,
the BLOB prefix is stored inline along with the row. So
the above error message is changed as follows depending on
the row format used:
For ROW_FORMAT=COMPRESSED or ROW_FORMAT=DYNAMIC, the error
message is as follows:
"ERROR 42000: Row size too large (> 8126). Changing some
columns to TEXT or BLOB may help. In current row format,
BLOB prefix of 0 bytes is stored inline."
For ROW_FORMAT=COMPACT or ROW_FORMAT=REDUNDANT, the error
message is as follows:
"ERROR 42000: Row size too large (> 8126). Changing some
columns to TEXT or BLOB or using ROW_FORMAT=DYNAMIC or
ROW_FORMAT=COMPRESSED may help. In current row
format, BLOB prefix of 768 bytes is stored inline."

PAGE SPLIT
page_rec_get_nth_const(): Map nth==0 to the page infimum.
btr_compress(adjust=TRUE): Add a debug assertion for nth>0. The cursor
should never be positioned on the page infimum.
btr_index_page_validate(): Add test instrumentation for checking the
return values of page_rec_get_nth_const() during CHECK TABLE, and for
checking that the page directory slot 0 always contains only one
record, the predefined page infimum record.
page_cur_delete_rec(), page_delete_rec_list_end(): Add debug
assertions guarding against accessing the page slot 0.
page_copy_rec_list_start(): Clarify a comment about ret_pos==0.

ha_innodb::records_in_range(): Remove a debug assertion
that prohibits an open range (full table).
The patch by Jorgen Loland only removed the assertion from the
built-in InnoDB, not from the InnoDB Plugin.
When we append data to the binlog file, we use fdatasync() to ensure
the data gets to disk so that crash recovery can work.
Unfortunately there seems to be a bug in ext3/ext4 on linux, so that
fdatasync() does not correctly sync all data when the size of a file
is increased. This causes crash recovery to not work correctly (it
loses transactions from the binlog).
As a work-around, use fsync() for the binlog, not fdatasync(). Since
we are increasing the file size, (correct) fdatasync() will most
likely not be faster than fsync() on any file system, and fsync()
does work correctly on ext3/ext4. This avoids the need to try to
detect if we are running on buggy ext3/ext4.
1. Field_newdate::get_date should refuse to return a date with zeros when
TIME_NO_ZERO_IN_DATE is set, not when TIME_FUZZY_DATE is unset
2. Item_func_to_days and Item_date_add_interval can only work with valid dates,
no zeros allowed.
fix Item_func_add_time::get_date() to generate valid dates.
Move the validity check inside get_date_from_daynr()
instead of relying on callers
(5 that had it, and 2 that did not, but should've)
- Full table scan internally uses LIMIT n, and re-starts the scan from
the last seen rowkey value. rowkey ranges are inclusive, so we will
see the same rowkey again. We should ignore it.
The use of Thread_iterator did not work on windows (linking problems).
Solution: Change the interface between the thread_pool and the server
to only use simple free functions.
This patch is for 5.5 only (mimicks similar solution in 5.6)
