380f1a8440 Bug#39040 valgrind errors/crash when creating views with binlog logging enabled
A string buffers which were included in the 'view' data structure
were allocated on the stack, causing an invalid pointer when used
after the function returned.
The fix: use copy of values for view->md5 & view->queries

0b8342ba4e Fixed bug #35193.
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.

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.

012aab7d8b Fix for bug #33049: Assert while running test-as3ap test(mysql-bench
suite)

Under some circumstances a combination of aggregate functions and
GROUP BY in a SELECT query over a VIEW could lead to incorrect
calculation of the result type of the aggregate function. This in
turn could result in incorrect results, or assertion failures on debug
builds.

Fixed by changing the logic in Item_sum_hybrid::fix_fields() so that
the argument's item is dereferenced before calling its type() method.

fa08b28085 Fix for Bug#34337: Server crash when Altering a view using
a table name.
  
The problem was that fill_defined_view_parts() did not return
an error if a table is going to be altered. That happened if
the table was already in the table cache. In that case,
open_table() returned non-NULL value (valid TABLE-instance from
the cache).
  
The fix is to ensure that an error is thrown even if the table
is in the cache.

7114fbb943 Bug#34587 Creating a view inside a stored procedure leads to a server crash
The problem is that when a stored procedure is being parsed for
the first execution, the body is copied to a temporary buffer
which is disregarded sometime after the statement is parsed.
And during this parsing phase, the rule for CREATE VIEW was
holding a reference to the string being parsed for use during
the execution of the CREATE VIEW statement, leading to invalid
memory access later.

The solution is to allocate and copy the SELECT of a CREATE
VIEW statement using the thread memory root, which is set to
the permanent arena of the stored procedure.

c1d0dd94bb Fix for Bug#32538: View definition picks up character set,
but not collation.

The problem here was that text literals in a view were always
dumped with character set introducer. That lead to loosing
collation information.

The fix is to dump character set introducer only if it was
in the original query. That is now possible because there 
is no problem any more of loss of character set of string
literals in views -- after WL#4052 the view is dumped 
in the original character set.

d5092fa9ca Fix for bug #33389: Selecting from a view into a table from within SP
or trigger crashes server

Under some circumstances a combination of VIEWs, subselects with outer
references and PS/SP/triggers could lead to use of uninitialized memory
and server crash as a result.

Fixed by changing the code in Item_field::fix_fields() so that in cases
when the field is a VIEW reference, we first check whether the field
is also an outer reference, and mark it appropriately before returning.

72ebb0aada Bug#29477: Not all fields of the target table were checked to have a default
value when inserting into a view.

The mysql_prepare_insert function checks all fields of the target table that
directly or indirectly (through a view) are specified in the INSERT
statement to have a default value. This check can be skipped if the INSERT
statement doesn't mention any insert fields. In case of a view this allows
fields that aren't mentioned in the view to bypass the check.

Now fields of the target table are always checked to have a default value
when insert goes into a view.

9395421a14 A test case for BUG#26676: VIEW using old table schema in a session.
The following clarification should be made in The Manual:

Standard SQL is quite clear that, if new columns are added
to a table after a view on that table is created with
"select *", the new columns will not become part of the view.
In all cases, the view definition (view structure) is frozen
at CREATE time, so changes to the underlying tables do not
affect the view structure.

aa4a3c9ad0 Bug#30020: Insufficient check led to a wrong info provided by the
information schema table.

The get_schema_views_record() function fills records in the view table of
the informations schema with data about given views. Among other info
the is_updatable flag is set. But the check whether the view is updatable or
not wasn't covering all cases thus sometimes providing wrong info.
This might led to a user confusion.

Now the get_schema_views_record function additionally calls to the 
view->can_be_merge() function to find out whether the view can be updated or
not.

5d88b654ed Fixed bug #29392.
This bug may manifest itself for select queries over a multi-table view
that includes an ORDER BY clause in its definition. If the select list of 
the query contains references to the same view column with different
aliases the names of the columns in the result output will be nevertheless
the same, coinciding with one of the alias.

The bug happened because the method Item_ref::get_tmp_table_item that
was inherited by the class Item_direct_view_ref ignored the fact that
the name of the view column reference must be inherited by the fields
of the temporary table that was created in order to get the result rows
sorted.

  Fixed bug #29392.
  This bug may manifest itself for select queries over a multi-table view
  that includes an ORDER BY clause in its definition. If the select list of 
  the query contains references to the same view column with different
  aliases the names of the columns in the result output will be nevertheless
  the same, coinciding with one of the alias.

  Fixed by providing a proper implementation of the get_tmp_table_item 
  method for the Item_direct_view_ref class.

405f82d390 Patch for the following bugs:
- BUG#11986: Stored routines and triggers can fail if the code
    has a non-ascii symbol
  - BUG#16291: mysqldump corrupts string-constants with non-ascii-chars
  - BUG#19443: INFORMATION_SCHEMA does not support charsets properly
  - BUG#21249: Character set of SP-var can be ignored
  - BUG#25212: Character set of string constant is ignored (stored routines)
  - BUG#25221: Character set of string constant is ignored (triggers)

There were a few general problems that caused these bugs:
1. Character set information of the original (definition) query for views,
   triggers, stored routines and events was lost.
2. mysqldump output query in client character set, which can be
   inappropriate to encode definition-query.
3. INFORMATION_SCHEMA used strings with mixed encodings to display object
   definition;

1. No query-definition-character set.

In order to compile query into execution code, some extra data (such as
environment variables or the database character set) is used. The problem
here was that this context was not preserved. So, on the next load it can
differ from the original one, thus the result will be different.

The context contains the following data:
  - client character set;
  - connection collation (character set and collation);
  - collation of the owner database;

The fix is to store this context and use it each time we parse (compile)
and execute the object (stored routine, trigger, ...).

2. Wrong mysqldump-output.

The original query can contain several encodings (by means of character set
introducers). The problem here was that we tried to convert original query
to the mysqldump-client character set.

Moreover, we stored queries in different character sets for different
objects (views, for one, used UTF8, triggers used original character set).

The solution is
  - to store definition queries in the original character set;
  - to change SHOW CREATE statement to output definition query in the
    binary character set (i.e. without any conversion);
  - introduce SHOW CREATE TRIGGER statement;
  - to dump special statements to switch the context to the original one
    before dumping and restore it afterwards.

Note, in order to preserve the database collation at the creation time,
additional ALTER DATABASE might be used (to temporary switch the database
collation back to the original value). In this case, ALTER DATABASE
privilege will be required. This is a backward-incompatible change.

3. INFORMATION_SCHEMA showed non-UTF8 strings

The fix is to generate UTF8-query during the parsing, store it in the object
and show it in the INFORMATION_SCHEMA.

Basically, the idea is to create a copy of the original query convert it to
UTF8. Character set introducers are removed and all text literals are
converted to UTF8.

This UTF8 query is intended to provide user-readable output. It must not be
used to recreate the object.  Specialized SHOW CREATE statements should be
used for this.

The reason for this limitation is the following: the original query can
contain symbols from several character sets (by means of character set
introducers).

Example:

  - original query:
    CREATE VIEW v1 AS SELECT _cp1251 'Hello' AS c1;

  - UTF8 query (for INFORMATION_SCHEMA):
    CREATE VIEW v1 AS SELECT 'Hello' AS c1;

39bf2b9662 Fixed bug #29104: assertion abort for grouping queries using views.
The abort happened when a query contained a conjunctive predicate
of the form 'view column = constant' in the WHERE condition and 
the grouping list also contained a reference to a view column yet
a different one.

Removed the failing assertion as invalid in a general case.

Also fixed a bug that prevented applying some optimization for grouping
queries using views. If the WHERE condition of such a query contains
a conjunctive condition of the form 'view column = constant' and
this view column is used in the grouping list then grouping by this
column can be eliminated. The bug blocked performing this elimination.

The result of the CHECK OPTION condition evaluation over an
updated record and records of merged tables was arbitrary and
dependant on the order of records in the merged tables during
the execution of SELECT statement.

The CHECK OPTION expression was evaluated over expired record
buffers (with arbitrary data in the fields).

Rowids of tables used in the CHECK OPTION expression were
added to temporary table rows. The multi_update::do_updates()
method was modified to restore necessary record buffers
before evaluation of the CHECK OPTION condition.
