d251e9be43 Bug#21269 (DEFINER-clause is allowed for UDF-functions)
The problem was that the grammar allows to create a function with an optional
definer clause, and define it as a UDF with the SONAME keyword.
Such combination should be reported as an error.

The solution is to not change the grammar itself, and to introduce a
specific check in the yacc actions in 'create_function_tail' for UDF,
that now reports ER_WRONG_USAGE when using both DEFINER and SONAME.

c8673b09b8 Bug #21080: ALTER VIEW makes user restate SQL SECURITY mode, and ALGORITHM
When executing ALTER TABLE all the attributes of the view were overwritten.
  This is contrary to the user's expectations.
  So some of the view attributes are preserved now : namely security and 
  algorithm. This means that if they are not specified in ALTER VIEW
  their values are preserved from CREATE VIEW instead of being defaulted.

0abc107cd2 Bug#16581: deadlock: server and client both read from connection in
'conc_sys' test

Concurrent execution of SELECT involing at least two INFORMATION_SCHEMA
tables, DROP DATABASE statement and DROP TABLE statement could have
resulted in stalled connection for this SELECT statement.

The problem was that for the first query of a join there was a race
between select from I_S.TABLES and DROP DATABASE, and the error (no
such database) was prepared to be send to the client, but the join
processing was continued.  On second query to I_S.COLUMNS there was a
race with DROP TABLE, but this error (no such table) was downgraded to
warning, and thd->net.report_error was reset.  And so neither result
nor error was sent to the client.

The solution is to stop join processing once it is clear we are going
to report a error, and also to downgrade to warnings file system errors
like 'no such database' (unless we are in the 'SHOW' command), because
I_S is designed not to use locks and the query to I_S should not abort
if something is dropped in the middle.

No test case is provided since this bug is a result of a race, and is
timing dependant.  But we test that plain SHOW TABLES and SHOW COLUMNS
give a error if there is no such database or a table respectively.


mysql-test/r/show_check.result:
  Add result for the test that SHOW TABLES and SHOW COLUMNS give a error
  if there is no such database or a table respectively.

sql/mysql_priv.h:

sql/sql_show.cc:
  Rename mysql_find_files() to find_files() and make it static.
  Return FIND_FILES_OK for success, FIND_FILES_OOM for out of memory,
  and FIND_FILES_DIR for directory reading error.
  Downgrade error to warning in get_all_tables() if it is a
  FIND_FILES_DIR error, and we are not in the 'SHOW' command.
  Once 'result' is set to 1 in get_schema_tables_result(), there's no
  need in continuing iterations, as we are about to return a error.

d36f578130 Fix for BUG#20438: CREATE statements for views, stored routines and triggers
can be not replicable.

Now CREATE statements for writing in the binlog are created as follows:
  - the beginning of the statement is re-created;
  - the rest of the statement is copied from the original query.

The problem appears when there is a version-specific comment (produced by
mysqldump), started in the re-created part of the statement and closed in the
copied part -- there is closing comment-parenthesis, but there is no opening
one.

The proper fix could be to re-create original statement, but we can not
implement it in 5.0. So, for 5.0 the fix is just to cut closing
comment-parenthesis. This technique is also used for SHOW CREATE PROCEDURE
statement (so we are able to reuse existing code).

3c10858474 Fix for BUG#16211: Stored function return type for strings is ignored.
Fix for BUG#16676: Database CHARSET not used for stored procedures

The problem in BUG#16211 is that CHARSET-clause of the return type for
stored functions is just ignored.

The problem in BUG#16676 is that if character set is not explicitly
specified for sp-variable, the server character set is used instead
of the database one.

The fix has two parts:

  - always store CHARSET-clause of the return type along with the
    type definition in mysql.proc.returns column. "Always" means that
    CHARSET-clause is appended even if it has not been explicitly
    specified in CREATE FUNCTION statement (this affects BUG#16211 only).

    Storing CHARSET-clause if it is not specified is essential to avoid
    changing character set if the database character set is altered in
    the future.

    NOTE: this change is not backward compatible with the previous releases.

  - use database default character set if CHARSET-clause is not explicitly
    specified (this affects both BUG#16211 and BUG#16676).

    NOTE: this also breaks backward compatibility.

6b75e24b73 * Bug #20792: Incorrect results from aggregate subquery
When processing aggregate functions all tables values are reset
to NULLs at the end of each group. 
When doing that if there are no rows found for a group
the const tables must not be reset as they are not recalculated 
by do_select()/sub_select() for each group.

  * Bug #20792: Incorrect results from aggregate subquery
   - test suite for the bug. This is dependent on InnoDB despite
     the fact that the bug and the fix are not InnoDB specific.
     This is because of the table flag HA_NOT_EXACT_COUNT.
     When this flag is off (as in MyISAM) both t2 and t3 become of
     join type 'system' as they are estimated to have 1 record and
     and this statistics can be trusted (according to the absence of
     HA_NOT_EXACT_COUNT).

5ca1ee5eea Bug #21019: First result of SELECT COUNT(*) different than consecutive runs
When optimizing conditions like 'a = <some_val> OR a IS NULL' so that they're
 united into a single condition on the key and checked together the server must 
 check which value is the NULL value in a correct way : not only using ->is_null 
 but also check if the expression doesn't depend on any tables referenced in the 
 current statement. 
 This additional check must be performed because that optimization takes place 
 before the actual execution of the statement, so if the field was initialized 
 to NULL from a previous statement the optimization would be applied incorrectly.

585b5bbc92 Fix for BUG#20954: avg(keyval) retuns 0.38 but max(keyval) returns an empty set
The problem was in that opt_sum_query() replaced MIN/MAX functions
with the corresponding constant found in a key, but due to imprecise
representation of float numbers, when evaluating the where clause,
this comparison failed.

When MIN/MAX optimization detects that all tables can be removed,
also remove all conjuncts in a where clause that refer to these

twice, and in the case of float number comparisons we do not discard

bug 12882.


mysql-test/r/func_group.result:
  BUG#20954 - test result adjustment.
  Adjusted the test result of bug 12882 which was not preperly fixed.
  The current patch corrects the problem that was fully corrected by the
  patch for 12882.
  
  The problem was that opt_sum_query() indicated that the optimizer may
  remove all tables because all MIN/MAX/COUNT functions are constants,
  but this lead to an empty result instead of NULL because the WHERE
  clause was still evaluated.
  
  The current fix removes all conjuncts in the where clause that
  reference the removed tables, and thus corrects the problem.
mysql-test/r/select.result:
  BUG#20954 - added test
mysql-test/r/subselect.result:
  BUG#20954 - test result adjustment.
  
  The fix removes those conditions in a where clause that refer to
  tables optimized away by MIN/MAX optimization (opt_sum_query()).

  BUG#20954 - added test
sql/sql_select.cc:
  Fix for BUG#20954: avg(keyval) retuns 0.38 but max(keyval) returns an empty set
  
  When MIN/MAX optimization detects that all tables can be removed,
  also remove all conjuncts in a where clause that refer to these
  tables. As a result of this fix, these conditions are not evaluated
  twice, and in the case of float number comparisons we do not discard
  result rows due to imprecise float representation.
  
  As a side-effect this fix also corrects an unnoticed problem in

9a63adc8fd Fixed bug#19862: Sort with filesort by function evaluates function twice
When there is no index defined filesort is used to sort the result of a
query. If there is a function in the select list and the result set should be
ordered by it's value then this function will be evaluated twice. First time to
get the value of the sort key and second time to send its value to a user.
This happens because filesort when sorts a table remembers only values of its
fields but not values of functions.
All functions are affected. But taking into account that SP and UDF functions
can be both expensive and non-deterministic a temporary table should be used 
to store their results and then sort it to avoid twice SP evaluation and to 
get a correct result.

If an expression referenced in an ORDER clause contains a SP or UDF 
function, force the use of a temporary table.

A new Item_processor function called func_type_checker_processor is added
to check whether the expression contains a function of a particular type.

1b3cdb6085 Bug #21086: server crashes when VIEW defined with a SELECT with COLLATE clause is called
When executing INSERT over a view with calculated columns it was assuming all
  elements of the fields collection are actually Item_field instances.
  This may not be true when inserting into a view and that view has columns that are 
  such expressions that allow updating (like setting a collation for example).
  Corrected to access field information through the filed_for_view_update() function and 
  retrieve correctly the field info even for "update-friendly" non-Item_field items.

4e7121c07b Bug#16712: group_concat returns odd srting insead of intended result
when calculating GROUP_CONCAT all blob fields are transformed
  to varchar when making the temp table.
  However a varchar has at max 2 bytes for length. 
  This fix makes the conversion only for blobs whose max length 
  is below that limit. 
  Otherwise blob field is created by make_string_field() call.

d64f605e48 Fixed bug #21231: wrong results for a simple query with a
a non-correlated single-row subquery over information schema.

The function get_all_tables filling all information schema
tables reset lex->sql_command to SQLCOM_SHOW_FIELDS. After
this the function could evaluate partial conditions related to
some columns. If these conditions contained a subquery over
information schema it led to a wrong evaluation and a wrong 
result set.
This bug was already fixed in 5.1.
This patch follows the way how it was done in 5.1 where
the value of lex->sql_command is set to SQLCOM_SHOW_FIELDS
in get_all_tables only for the calls of the function 
open_normal_and_derived_tables and is restored after these
calls.

43df9fd34c Fixed bug #18925: wrong results for queries with
subqueries on information schema that use MIN/MAX aggregation.

Execution of some correlated subqueries may set the value
of null_row to 1 for tables used in the subquery.
If the the subquery is on information schema it causes
rejection of any row for the following executions of
the subquery in the case when an optimization filtering
by some condition is applied.

The fix restores the value of the null_row flag for 
each execution of a subquery on information schema.
