The REPAIR TABLE ... USE_FRM query silently corrupts data of tables
with old .FRM file version.
The mysql_upgrade client program or the REPAIR TABLE query (without
the USE_FRM clause) can't prevent this trouble, because in the
common case they don't upgrade .FRM file to compatible structure.
1. Evaluation of the REPAIR TABLE ... USE_FRM query has been
modified to reject such tables with the message:
"Failed repairing incompatible .FRM file".
2. REPAIR TABLE query (without USE_FRM clause) evaluation has been
modified to upgrade .FRM files to current version.
3. CHECK TABLE ... FOR UPGRADE query evaluation has been modified
to return error status when .FRM file has incompatible version.
4. mysql_upgrade and mysqlcheck client programs call CHECK TABLE
FOR UPGRADE and REPAIR TABLE queries, so their behaviors have
been changed too to upgrade .FRM files with incompatible
version numbers.

The bug is a regression introduced by the patch for bug32798.
The code in Item_func_group_concat::clear() relied on the 'distinct'
variable to check if 'unique_filter' was initialized. That, however,
is not always valid because Item_func_group_concat::setup() can do
shortcuts in some cases w/o initializing 'unique_filter'.
Fixed by checking the value of 'unique_filter' instead of 'distinct'
before dereferencing.

When a zero length is provided to the my_decimal_length_to_precision
function along with unsigned_flag set to false it returns a negative value.
For queries that employs temporary tables may cause failed assertion or
excessive memory consumption while temporary table creation.

functions take unsigned_flag into account only if the length/precision
argument is non-zero.

1. JOIN::prepare initializes JOIN::table counter (actually a size
of the JOIN::join_tab array) and sets it to a number of joined tables.
2. The make_join_statistics function (when called from JOIN::optimize)
allocates and fills the JOIN::join_tab array.
However, when optimizing subselect has impossible (definite false)
WHERE or HAVING clause, optimizer skips call to make_join_statistics
and leaves JOIN::join_tab == NULL.
3. subselect_single_select_engine::exec does traversal of the JOIN::join_tab
array and the server dies because array is not allocated but array
counter is greater than 0.
The JOIN::optimize method has been modified to reset the JOIN::table
counter to 0 in cause of impossible WHERE/HAVING clause.
Grouping or ordering of long values in not indexed BLOB/TEXT columns
with GBK or BIG5 charsets crashes the server.
MySQL server uses sorting (the filesort procedure) in the temporary
table to evaluate the GROUP BY clause in case of lack of suitable index.
That procedure takes into account only first @max_sort_length bytes
(system variable, usually 1024) of TEXT/BLOB sorting key string.
The my_strnxfrm_gbk and my_strnxfrm_big5 fill temporary keys
with data of whole blob length instead of @max_sort_length bytes
length. That buffer overrun has been fixed.

Make maximum blob size to be 2**32-1, regardless of word size.
Fix failure of timestamp with size of 2**31-1. The method of
rounding up to the nearest even number would overflow.

2**32-1 is not a special case for timestamp.
Test 2**32-1 and 2**64 as the reliable test points for both 32-

tests that vary between architectures.
I'd like to generalize the tests by pulling the max blob size from
the server, and then "eval"ing N-1, N, and N+1 instead of all these
literal numbers, but I have not found a way to get UINT_MAX.

number.

The problem was that LOAD DATA code (sql_load.cc) didn't take into
account that there may be items, representing references to other
columns. This is a usual case in views. The crash happened because
Item_direct_view_ref was casted to Item_user_var_as_out_param,
which is not a base class.
The fix is to
1) Handle references properly;
2) Ensure that an item is treated as a user variable only when
it is a user variable indeed;
3) Report an error if LOAD DATA is used to load data into
non-updatable column.

Mixing aggregate functions and non-grouping columns is not allowed in the
ONLY_FULL_GROUP_BY mode. However in some cases the error wasn't thrown because
of insufficient check.
In order to check more thoroughly the new algorithm employs a list of outer
fields used in a sum function and a SELECT_LEX::full_group_by_flag.
Each non-outer field checked to find out whether it's aggregated or not and
the current select is marked accordingly.
All outer fields that are used under an aggregate function are added to the
Item_sum::outer_fields list and later checked by the Item_sum::check_sum_func
function.

View definition as SELECT ... FROM DUAL WHERE ... has
valid syntax, but use of such view in SELECT or
SHOW CREATE VIEW syntax causes unexpected syntax error.
Server omits FROM DUAL clause when storing view body
string in a .frm file for further evaluation.
However, syntax of SELECT-witout-FROM query is more
restrictive than SELECT FROM DUAL syntax, and doesn't
allow the WHERE clause.
NOTE: this syntax difference is not documented.
View registration procedure has been modified to
preserve original structure of view's body.

Added test case for bug #35193.
mysql-test/t/view.test:
Added test case for bug #35193.
sql/sql_select.cc:
Fixed bug #35193.
The st_select_lex::print function always omits FROM DUAL clause,
even if original SELECT query has the WHERE clause.
The mysql_register_view function uses this function to reconstruct
a body of view's AS clause for further evaluation and stores that
reconstructed clause in a .frm file.
SELECT without FROM syntax is more restrictive than
SELECT FROM DUAL syntax: second one allows
the WHERE clause, but first one is not.
Use of this view in SELECT or SHOW CREATE VIEW queries
causes unexpected syntax errors.
The st_select_lex::print function has been modified to
reconstruct FROM DUAL clause in queries when needed.
TODO: Syntax difference is not documented and should be
eliminated, however improvement of
the SELECT-without-FROM syntax is not trivial and leads to
significant modification of grammar file because of additional
shift/reduce conflicts.
