If the spatial key is used within an equality comparison, the comparison
does not produce relevant results generally as identical geometry can be
stored differently. Still, we want to support the operation. In order
to allow a hash join plan, we must define a key_length for Field_geom.
The GEOMETRY field metadata is stored in the FRM file.
SRID for a spatial column now can be stored, it was added to the CREATE TABLE syntax,
so the AddGeometryData() stored procedure is now possible. Script adding the required Add/DropGeometryColumn sp-s added.
length/dec/charset are still in LEX, because they're also used
for CAST and dynamic columns.
also
1. fix "MDEV-7041 COLLATION(CAST('a' AS CHAR BINARY)) returns a wrong result"
2. allow BINARY modifier in stored function RETURN clause
3. allow "COLLATION without CHARSET" in SP/SF (parameters, RETURN, DECLARE)
4. print correct variable name in error messages for stored routine parameters
This is port of fix for MySQL BUG#17647863.

Bug#17647863: MYSQL DOES NOT COMPILE ON OSX 10.9 GM
Rename test() macro to MY_TEST() to avoid conflict with libc++.
(MYSQLBINLOG -V CRASHES WITH THAT BINLOG)
Problem: If slave receives a corrupted row event,
slave server is crashing.
Analysis: When slave is unpacking the row event, it is
not validating the data before applying the event. If the
data is corrupted for eg: the length of a field is wrong,
it could end up reading wrong data leading to a crash.
A similar problem happens when mysqlbinlog tool is used
against a corrupted binlog using '-v' option. Due to -v
option, the tool tries to print the values of all the
fields. Corrupted field length could lead to a crash.
Fix: Before unpacking the field, a verification
will be made on the length. If it falls into the event
range, only then it will be unpacked. Otherwise,
"ER_SLAVE_CORRUPT_EVENT" error will be thrown.
Incase mysqlbinlog -v case, the field value will not be
printed and the processing of the file will be stopped.
sql/field.h:
Removed a function which is not required anymore
sql/log_event.cc:
Adding a validation on the field length before
the tool tries to print the value.
sql/log_event.h:
Changing unpack_row call according to the new arguments
sql/log_event_old.h:
Changing unpack_row call according to the new arguments
sql/rpl_record.cc:
Adding a new argument 'row_end' which tells
the end position of the complete data in the
row event. It will be used to do validation
before doing 'unpack' field.
sql/rpl_record.h:
Adding a new argument 'row_end' which tells
the end position of the complete data in the
row event. It will be used to do validation
before doing 'unpack' field.
sql/rpl_utility.cc:
Now calc_field_size() is required for client too.
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
Includes 5.6 changesets for:
*****
Fix for BUG#13489996 valgrind:conditional jump or move depends on uninitialised values-field_blob.
blob_ptr_size was not initialized properly: remove this variable.
