Do not silence uncertain cases, or fix any bugs.
The only functional change should be that ha_federated::extra()
is not calling DBUG_PRINT to report an unhandled case for
HA_EXTRA_PREPARE_FOR_DROP.
Role names with trailing whitespaces are truncated in length as of
956e92d908 to fix MDEV-8609. The problem
is that the code that creates role mappings expects the string to be null
terminated.
Add the null terminator to account for that as well. In the future
the rest of the code can be cleaned up to never assume c style strings
but only LEX_STRINGS.
IS USED IN CREATE TABLE
The problem was that using a very long subpartition name could
lead to the server exiting abnormally.
This patch fixes the problem by reporting ER_TOO_LONG_IDENT
if a name with more than 64 characters are used as partition
and subpartition name.
GET_SERVER_FROM_TABLE_TO_CACHE
Description:- Server received SIG11 in the function,
"get_server_from_table_to_cache()".
Analysis:- Defining a server with a blank name is not
handled properly.
Fix:- Modified "get_server_from_table_to_cache()" to
take care of blank server name.
Analysis :
==========
During JOIN::prepare of sub-query which creates the
derived tables we call setup_procedure. Here we call
fix_fields for parameters of procedure clause. Calling
setup_procedure at this point may cause issue. If
sub-query is one of parameter being fixed it might
lead to complicated dependencies on derived tables
being prepared.
SOLUTION :
==========
In 5.6 with WL#6242, we have made procedure clause
parameters can only be NUM, so sub-queries are not
allowed as parameters. So in 5.5 we can block
sub-queries in procedure clause parameters.
This eliminates above conflicting dependencies.
remove the code that checks for correct options for
for CHECK/REPAIR VIEW. Rewrite the grammar for the parser
to check that. This changes error messages as
-ERROR 42000: You have an error ... near '' at line 1
+ERROR 42000: You have an error ... near 'quick' at line 1

Why? REPAIR NO_WRITE_TO_BINLOG VIEW makes perfect sense to me, why did
you want to disallow it?

Merged upstream fix to Bug#16221433 MYSQL REJECTS QUERY DUE TO BAD
RESOLUTION OF NAMES IN HAVING; VIEW UNREADABLE
authored by Guilhem Bichot <guilhem.bichot@oracle.com>.
ISSUE:
------
We pre-allocate the ref_pointer_array before we resolve outer
references. This means that in some cases the
ref_pointer_array may not be large enough to hold all
references created. One such case is aggregate functions in
having clause of a subquery which may add items to select list
of outer query. So it is necessary to consider
select_n_having_items for subqueries while allocating
ref_pointer_array else we will get buffer overflow.
SOLUTION:
---------
Allocate a larger ref_pointer_array by aggregating
select_n_having_items for subqueries.
The fix in sql_yacc.yy is a backport from bug fix 18782905.
When parsing a field declaration, grab type information from LEX before it's overwritten
by further rules. Pass type information through the parser stack to the rule that needs it.
