The problems were:

Bug 26379 - Combination of FLUSH TABLE and REPAIR TABLE
                corrupts a MERGE table

  1. A thread trying to lock a MERGE table performs busy waiting while
     REPAIR TABLE or a similar table administration task is ongoing on
     one or more of its MyISAM tables.
  
  2. A thread trying to lock a MERGE table performs busy waiting until all
     threads that did REPAIR TABLE or similar table administration tasks
     on one or more of its MyISAM tables in LOCK TABLES segments do UNLOCK
     TABLES. The difference against problem #1 is that the busy waiting
     takes place *after* the administration task. It is terminated by
     UNLOCK TABLES only.
  
  3. Two FLUSH TABLES within a LOCK TABLES segment can invalidate the
     lock. This does *not* require a MERGE table. The first FLUSH TABLES
     can be replaced by any statement that requires other threads to
     reopen the table. In 5.0 and 5.1 a single FLUSH TABLES can provoke
     the problem.

Bug 26867 - LOCK TABLES + REPAIR + merge table result in
            memory/cpu hogging

  Trying DML on a MERGE table, which has a child locked and
  repaired by another thread, made an infinite loop in the server.

Bug 26377 - Deadlock with MERGE and FLUSH TABLE

  Locking a MERGE table and its children in parent-child order
  and flushing the child deadlocked the server.

Bug 25038 - Waiting TRUNCATE

  Truncating a MERGE child, while the MERGE table was in use,
  let the truncate fail instead of waiting for the table to
  become free.

Bug 25700 - merge base tables get corrupted by
            optimize/analyze/repair table

  Repairing a child of an open MERGE table corrupted the child.
  It was necessary to FLUSH the child first.

Bug 30275 - Merge tables: flush tables or unlock tables
            causes server to crash

  Flushing and optimizing locked MERGE children crashed the server.

Bug 19627 - temporary merge table locking

  Use of a temporary MERGE table with non-temporary children
  could corrupt the children.

  Temporary tables are never locked. So we do now prohibit
  non-temporary chidlren of a temporary MERGE table.

Bug 27660 - Falcon: merge table possible

  It was possible to create a MERGE table with non-MyISAM children.

Bug 30273 - merge tables: Can't lock file (errno: 155)

  This was a Windows-only bug. Table administration statements
  sometimes failed with "Can't lock file (errno: 155)".

These bugs are fixed by a new implementation of MERGE table open.

When opening a MERGE table in open_tables() we do now add the
child tables to the list of tables to be opened by open_tables()
(the "query_list"). The children are not opened in the handler at
this stage.

After opening the parent, open_tables() opens each child from the
now extended query_list. When the last child is opened, we remove
the children from the query_list again and attach the children to
the parent. This behaves similar to the old open. However it does
not open the MyISAM tables directly, but grabs them from the already
open children.

When closing a MERGE table in close_thread_table() we detach the
children only. Closing of the children is done implicitly because
they are in thd->open_tables.

For more detail see the comment at the top of ha_myisammrg.cc.

Changed from open_ltable() to open_and_lock_tables() in all places
that can be relevant for MERGE tables. The latter can handle tables
added to the list on the fly. When open_ltable() was used in a loop
over a list of tables, the list must be temporarily terminated
after every table for open_and_lock_tables().
table_list->required_type is set to FRMTYPE_TABLE to avoid open of
special tables. Handling of derived tables is suppressed.
These details are handled by the new function
open_n_lock_single_table(), which has nearly the same signature as
open_ltable() and can replace it in most cases.

In reopen_tables() some of the tables open by a thread can be
closed and reopened. When a MERGE child is affected, the parent
must be closed and reopened too. Closing of the parent is forced
before the first child is closed. Reopen happens in the order of
thd->open_tables. MERGE parents do not attach their children
automatically at open. This is done after all tables are reopened.
So all children are open when attaching them.

Special lock handling like mysql_lock_abort() or mysql_lock_remove()
needs to be suppressed for MERGE children or forwarded to the parent.
This depends on the situation. In loops over all open tables one
suppresses child lock handling. When a single table is touched,
forwarding is done.

Behavioral changes:
===================

This patch changes the behavior of temporary MERGE tables.
Temporary MERGE must have temporary children.
The old behavior was wrong. A temporary table is not locked. Hence
even non-temporary children were not locked. See
Bug 19627 - temporary merge table locking.

You cannot change the union list of a non-temporary MERGE table
when LOCK TABLES is in effect. The following does *not* work:
CREATE TABLE m1 ... ENGINE=MRG_MYISAM ...;
LOCK TABLES t1 WRITE, t2 WRITE, m1 WRITE;
ALTER TABLE m1 ... UNION=(t1,t2) ...;
However, you can do this with a temporary MERGE table.

You cannot create a MERGE table with CREATE ... SELECT, neither
as a temporary MERGE table, nor as a non-temporary MERGE table.
CREATE TABLE m1 ... ENGINE=MRG_MYISAM ... SELECT ...;
Gives error message: table is not BASE TABLE.

6e668b4f5b Bug#21136 CREATE TABLE SELECT within CREATE TABLE SELECT causes server crash 
When CREATE TEMPORARY TABLE .. SELECT is invoked from a stored function
which in turn is called from CREATE TABLE SELECT causes a memory leak
because the inner create temporary table overrides the outter extra_lock
reference when locking the table.

The solution is to simply not overrride the extra_lock by only using the
extra_lock for a non-temporary table lock.

c4d53e31b0 Bug#15130: CREATE .. SELECT was denied to use advantages of the SQL_BIG_RESULT. 
When the SQL_BIG_RESULT flag is specified SELECT should store items from the
select list in the filesort data and use them when sending to a client.
The get_addon_fields function is responsible for creating necessary structures
for that. But this function was allowed to do so only for SELECT and
INSERT .. SELECT queries. This makes the SQL_BIG_RESULT useless for
the CREATE .. SELECT queries.

Now the get_addon_fields allows storing select list items in the filesort
data for the CREATE .. SELECT queries.

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;

0c31d0bbd7 Bug #26642: create index corrupts table definition in .frm 
Thanks to Martin Friebe for finding and submitting a fix for this bug!
  
  A table with maximum number of key segments and maximum length key name
  would have a corrupted .frm file, due to an incorrect calculation of the
  complete key length.  Now the key length is computed correctly (I hope) :-)
  
  MyISAM would reject a table with the maximum number of keys and the maximum
  number of key segments in all keys.  It would allow one less than this total
  maximum.  Now MyISAM accepts a table defined with the maximum.  (This is a
  very minor issue.)

0f6047e455 Bug #28842 Different 'duplicate key' error code between 5.0 and 5.1 
The patch for WL 1563 added a new duplicate key error message so that the
  key name could be provided instead of the key number. But the error code
  for the new message was used even though that did not need to change.

  This could cause unnecessary problems for applications that used the old
  ER_DUP_ENTRY error code to detect duplicate key errors.

206a6bb176 5.1 version of fix for: 
Bug #23667 "CREATE TABLE LIKE is not isolated from alteration
              by other connections"
  Bug #18950 "CREATE TABLE LIKE does not obtain LOCK_open"
As well as:
  Bug #25578 "CREATE TABLE LIKE does not require any privileges
              on source table".

The first and the second bugs resulted in various errors and wrong
binary log order when one tried to execute concurrently CREATE TABLE LIKE
statement and DDL statements on source table or DML/DDL statements on its
target table.

The problem was caused by incomplete protection/table-locking against
concurrent statements implemented in mysql_create_like_table() routine.
We solve it by simply implementing such protection in proper way.
Most of actual work for 5.1 was already done by fix for bug 20662 and
preliminary patch changing locking in ALTER TABLE.

The third bug allowed user who didn't have any privileges on table create
its copy and therefore circumvent privilege check for SHOW CREATE TABLE.

This patch solves this problem by adding privilege check, which was missing.

Finally it also removes some duplicated code from mysql_create_like_table()
and thus fixes bug #26869 "TABLE_LIST::table_name_length inconsistent with
TABLE_LIST::table_name".


mysql-test/r/create-big.result:
  Added test coverage for concurrency-related issues with CREATE TABLE LIKE.
mysql-test/r/create.result:
  Adjusted error-code in the test case after refactoring code that
  implements CREATE TABLE ... LIKE.
mysql-test/r/grant2.result:
  Added test for bug#25578 "CREATE TABLE LIKE does not require any privileges
  on source table".
mysql-test/t/create-big.test:
  Added test coverage for concurrency-related issues with CREATE TABLE LIKE.
mysql-test/t/create.test:
  Adjusted error-code in the test case after refactoring code that
  implements CREATE TABLE ... LIKE.
mysql-test/t/disabled.def:
  Recent code changes ensured that CREATE TABLE LIKE statement is properly
  isolated against other statements, so synchronization.test should no
  longer fail (see fix for bug 20662 and preliminary patch for bug 23667
  changing ALTER TABLE locking).
mysql-test/t/grant2.test:
  Added test for bug#25578 "CREATE TABLE LIKE does not require any privileges
  on source table".
sql/handler.h:
  Introduced new flag for HA_CREATE_INFO::options in order to be able to
  distinguish CREATE TABLE ... LIKE from other types of CREATE TABLE.
sql/mysql_priv.h:
  mysql_create_like_table() now takes source table name not as a
  Table_ident object but as regular table list element.
sql/sql_lex.h:
  Removed LEX::like_name member. Now we use special flag in
  LEX::create_info::options for distinguishing CREATE TABLE ... LIKE
  from other types of CREATE TABLE and store name of source table as
  regular element in statement's table list.
sql/sql_parse.cc:
  CREATE TABLE ... LIKE implementation now uses statement's table list
  for storing information about the source table. We also use flag
  in LEX::create_info.options for distinguishing it from other types
  of CREATE TABLE.
  Finally CREATE TABLE ... LIKE now requires the same privileges on
  the source tables as SHOW CREATE TABLE. Moved this privilege check
  to check_show_create_table_access() function.
sql/sql_partition.cc:
  Now we use special flag in LEX::create_info::options for distinguishing
  CREATE TABLE ... LIKE from other types of CREATE TABLE and store name
  of source table as regular element in statement's table list.
sql/sql_table.cc:
  mysql_create_like_table():  
   - Commented and cleaned-up a bit code which is responsible for achieving
     isolation from concurrent statements. Most of actual work was done by
     fix for bug 20662 and preliminary patch changing locking locking in
     ALTER TABLE, so here we do minor things like relaxing locking on
     source table (we don't need lock on it, to have it open is enough) and
     adjusting code to make it more friendly against code implementing I_S.
   - Get rid of duplicated code related to source database/table name
     handling. All these operations are already done in
     st_select_lex::add_table_to_list(), so we achieve the same effect
     by including source table into the statement's table list.
sql/sql_yacc.yy:
  Now we use special flag in LEX::create_info::options for distinguishing
  CREATE TABLE ... LIKE from other types of CREATE TABLE and store name
  of source table as regular element in statement's table list.

d46c8ce634 Fix for: 
Bug #20662 "Infinite loop in CREATE TABLE IF NOT EXISTS ... SELECT
              with locked tables"
  Bug #20903 "Crash when using CREATE TABLE .. SELECT and triggers"
  Bug #24738 "CREATE TABLE ... SELECT is not isolated properly"
  Bug #24508 "Inconsistent results of CREATE TABLE ... SELECT when
              temporary table exists"

Deadlock occured when one tried to execute CREATE TABLE IF NOT
EXISTS ... SELECT statement under LOCK TABLES which held
read lock on target table.
Attempt to execute the same statement for already existing
target table with triggers caused server crashes.
Also concurrent execution of CREATE TABLE ... SELECT statement
and other statements involving target table suffered from
various races (some of which might've led to deadlocks).
Finally, attempt to execute CREATE TABLE ... SELECT in case
when a temporary table with same name was already present
led to the insertion of data into this temporary table and
creation of empty non-temporary table.
 
All above problems stemmed from the old implementation of CREATE
TABLE ... SELECT in which we created, opened and locked target
table without any special protection in a separate step and not
with the rest of tables used by this statement.
This underminded deadlock-avoidance approach used in server
and created window for races. It also excluded target table
from prelocking causing problems with trigger execution.

The patch solves these problems by implementing new approach to
handling of CREATE TABLE ... SELECT for base tables.
We try to open and lock table to be created at the same time as
the rest of tables used by this statement. If such table does not
exist at this moment we create and place in the table cache special
placeholder for it which prevents its creation or any other usage
by other threads.
We still use old approach for creation of temporary tables.

Note that we have separate fix for 5.0 since there we use slightly
different less intrusive approach.


mysql-test/r/create.result:
  Extended test coverage for CREATE TABLE ... SELECT. In particular added
  tests for bug #24508 "Inconsistent results of CREATE TABLE ... SELECT
  when temporary table exists" and bug #20662 "Infinite loop in CREATE
  TABLE IF NOT EXISTS ... SELECT with locked tables".
mysql-test/r/trigger.result:
  Added test case for bug #20903 "Crash when using CREATE TABLE .. SELECT
  and triggers"
mysql-test/t/create.test:
  Extended test coverage for CREATE TABLE ... SELECT. In particular added
  tests for bug #24508 "Inconsistent results of CREATE TABLE ... SELECT
  when temporary table exists" and bug #20662 "Infinite loop in CREATE
  TABLE IF NOT EXISTS ... SELECT with locked tables".
mysql-test/t/trigger.test:
  Added test case for bug #20903 "Crash when using CREATE TABLE .. SELECT
  and triggers"
sql/lock.cc:
  Now for creation of name-lock placeholder lock_table_name() uses
  auxiliary function table_cache_insert_placeholder().
sql/mysql_priv.h:
  Removed declaration of non-existing build_table_path() routine.
  The former mysql_create_table_internal() was renamed to
  mysql_create_table_no_lock() and now exposed to other modules to
  give them opportunity of creation of tables in cases when name-lock
  is already obtained.
  reopen_name_locked_table() now has 3rd argument which controls linking
  in of table being opened into THD::open_tables (this is useful in
  cases when placeholder used for name-locking is already linked into
  this list).
  Added declaration of auxiliary function table_cache_insert_placeholder()
  which is used for creation of table placeholders for name-locking.
  Added declaration of lock_table_name_if_not_cached() which can be
  used to take an exclusive name-lock on table if there are no records
  for it in table cache.
  Changed signature of unlink_open_table() function to simplify its use
  and make it useful for table placeholders and tables that are only open.
  Added auxiliary drop_open_table() routine.
  Moved declaration of refresh_version to table.h header to make it
  accessible from inline methods of TABLE class.
  MYSQL_OPEN_IGNORE_LOCKED_TABLES flag is no longer used. Instead
  MYSQL_OPEN_TEMPORARY_ONLY option was added.
sql/sql_base.cc:
  Added support for the new approach to the handling of CREATE TABLE
  ... SELECT for base tables.
  
  Now we try to open and lock table to be created at the same time as
  the rest of tables used by this statement. If such table does not
  exist at this moment we create and place in the table cache special
  placeholder for it which prevents its creation or any other usage
  by other threads.
  
  Note significant distinctions of this placeholder from the placeholder
  used for normal name-lock: 1) It is treated like open table by other
  name-locks so it does not allow name-lock taking operations like DROP
  TABLE or RENAME TABLE to proceed. 2) it is linked into THD::open_tables
  list and automatically removed during close_thread_tables() call
    
  open_tables():
    Implemented logic described above. To do this added
    auxiliary check_if_table_exists() function.
    Removed support for MYSQL_OPEN_IGNORE_LOCKED_TABLES option
    which is no longer used.
    Added MYSQL_OPEN_TEMPORARY_ONLY which is used to restrict
    search for temporary tables only.
  close_cached_tables()/close_thread_table()/reopen_tables()/
  close_old_data_files()/table_is_used()/remove_table_from_cache():
    Added support for open placeholders (note that we also use them
    when we need to re-open tables during flush).
  unlink_open_table():
    Changed function signature to simplify its use and to make
    useful for open placeholders and tables which are only
    open and not locked.
  Added auxiliary drop_open_table() routine.
  reopen_name_locked_table():
    Now has 3rd argument which controls linking in of table being
    opened into THD::open_tables (this is useful in cases when
    placeholder used for name-locking is already linked into
    this list).
  Added auxiliary table_cache_insert_placeholder() routine which
  simplifies creation of placeholders used for name-locking.
  Added lock_table_name_if_not_cached() which can be used to take
  an exclusive name-lock on table if there are no records for it
  in table cache.
sql/sql_handler.cc:
  Adjusted mysql_ha_mark_tables_for_reopen() routine to properly
  handle placeholders which now can be linked into open tables
  list.
sql/sql_insert.cc:
  Introduced new approach to handling of base tables in CREATE TABLE
  ... SELECT statement.
  
  Now we try to open and lock table to be created at the same time as
  the rest of tables used by this statement. If such table does not
  exist at this moment we create and place in the table cache special
  placeholder for it which prevents its creation or any other usage
  by other threads. By doing this we avoid races which existed with
  previous approach in which we created, opened and locked target in
  separate step without any special protection.
  This also allows properly calculate prelocking set in cases when
  target table already exists and has some on insert triggers.
  
  Note that we don't employ the same approach for temporary tables
  (this is okay as such tables are unaffected by other threads).
  
  Changed create_table_from_items() and methods of select_create
  class to implement this approach.
sql/sql_parse.cc:
  The new approach to handling of CREATE TABLE ... SELECT for
  base tables assumes that all tables (including table to be
  created) are opened and (or) locked at the same time.
  So in cases when we create base table we have to pass to
  open_and_lock_tables() table list which includes target table.
sql/sql_prepare.cc:
  The new approach to handling of CREATE TABLE ... SELECT for
  base tables assumes that all tables (including table to be
  created) are opened and (or) locked at the same time.
  So in cases when we create base table we have to pass to
  open_and_lock_tables() table list which includes target table.
sql/sql_table.cc:
  Changed mysql_create_table(), mysql_create_like_table() and
  mysql_alter_table() (in rename case) to obtain exclusive name-lock
  on the non-temporary table which is going to be created (to which
  we going to rename). This ensures that not only destination table
  doesn't exist on disk but also that there are no placeholder in 
  table cache for it (i.e. there is no CREATE TABLE ... SELECT operation
  in progress for it). Note that to avoid deadlocks while taking these
  name-locks this code assumes that existence of any record for table in
  table cache (even name-lock) means that table exists. Altough such
  check can lead to false positives these should occur only in case of
  highly concurrent DDL operations on the table and should not break
  binary logging.
  
  Renamed mysql_create_table_internal() to mysql_create_table_no_lock()
  and made it accessible from other files to give them ability to create
  table in situation when name-lock is already obtained or not relevant.
  
  Adjusted calls to reopen_name_locked_table(), which now takes
  extra argument, which controls linking of open table into
  THD::open_tables list.
  
  Removed redundant setting of table's 'version' field before calls
  to close_cached_table(). This function will set it to 0 itself
  anyway.
sql/sql_trigger.cc:
  reopen_name_locked_tables() now has one more argument which controls
  linking of opened table into the THD::open_tables list.
sql/sql_yacc.yy:
  The new approach to handling of CREATE TABLE ... SELECT statement
  for base tables assumes that all tables including table to be
  created are open and (or) locked at the same time. Therefore
  we need to set correct lock for target table.
sql/table.h:
  Moved declaration of refresh_version variable from mysql_priv.h
  to make it accessible from inline methods of TABLE class.
  Renamed TABLE::locked_by_flush member to open_placeholder since
  now it is also used for taking exclusive name-lock and not only
  by flush. 
  Introduced TABLE::is_name_opened() helper method which can be used
  to distinguish TABLE instances corresponding to open tables or
  placeholders for them from closed instances (e.g. due to their old
  version). Also introduced TABLE::needs_reopen_or_name_lock() helper
  which allows to check if TABLE instance corresponds to outdated
  version of table or to name-lock placeholder.
  Introduced TABLE_LIST::create member which marks elements of
  table list corresponds to the table to be created.
  Adjusted TABLE_LIST::placeholder() method to take into account 
  name-lock placeholders for tables to be created (this, for example,
  allows to properly handle such placeholders in lock_tables()).
  Finally, moved currently unused TABLE::open_next/open_prev
  members under ifdef NOT_YET.
mysql-test/r/create_select-big.result:

We still use old approach for creation of temporary tables.

Also note that we decided to postpone introduction of some tests
for concurrent behaviour of CREATE TABLE ... SELECT till 5.1.
The main reason for this is absence in 5.0 ability to set @@debug
variable at runtime, which can be circumvented only by using several
test files with individual .opt files. Since the latter is likely
to slowdown test-suite unnecessary we chose not to push this tests
into 5.0, but run them manually for this version and later push
their optimized version into 5.1


mysql-test/r/create.result:
  Extended test coverage for CREATE TABLE ... SELECT. In particular added

  Added declaration of auxiliary function table_cache_insert_placeholder()
  which is used for creation of table placeholders for name-locking.
  Added declaration of table_cache_has_open_placeholder() function which
  can be used for checking if table cache contains an open placeholder for
  the table and if this placeholder was created by another thread.
  (This function is needed only in 5.0 where we use it in various versions
   of CREATE TABLE in order to protect it from concurrent CREATE TABLE
   ... SELECT operations for the table. Starting from 5.1 we use different
   approach so it is going to be removed there).
  Made close_old_data_files() static within sql_base.cc file. 
  Added auxiliary drop_open_table() routine.
  Moved declaration of refresh_version to table.h header to make it
  accessible from inline methods of TABLE class.
  MYSQL_OPEN_IGNORE_LOCKED_TABLES flag is no longer used. Instead
  MYSQL_OPEN_TEMPORARY_ONLY option was added.

  Also made build_table_path() available from other files and

0b72b7f0a4 Bug #26642: create index corrupts table definition in .frm 
Thanks to Martin Friebe for finding and submitting a fix for this bug!

A table with maximum number of key segments and maximum length key name
would have a corrupted .frm file, due to an incorrect calculation of the
complete key length.  Now the key length is computed correctly (I hope) :-)

MyISAM would reject a table with the maximum number of keys and the maximum
number of key segments in all keys.  It would allow one less than this total
maximum.  Now MyISAM accepts a table defined with the maximum.  (This is a
very minor issue.)


myisam/mi_open.c:
  change >= to > in a comparison (i.e., error only if key_parts_in_table
  really is greater than MAX_KEY * MAX_KEY_SEG)
mysql-test/r/create.result:
  Add test results for bug #26642 (create index corrupts table definition in .frm)
mysql-test/t/create.test:
  Add test case for bug #26642 (create index corrupts table definition in .frm)

aa32336198 Bug #24791: Union with AVG-groups generates wrong results 
The problem in this bug is when we create temporary tables. When
temporary tables are created for unions, there is some 
inferrence being carried out regarding the type of the column.
Whenever this column type is inferred to be REAL (i.e. FLOAT or
DOUBLE), MySQL will always try to maintain exact precision, and
if that is not possible (there are hardware limits, since FLOAT
and DOUBLE are stored as approximate values) will switch to
using approximate values. The problem here is that at this point
the information about number of significant digits is not 
available. Furthermore, the number of significant digits should
be increased for the AVG function, however, this was not properly 
handled. There are 4 parts to the problem:

#1: DOUBLE and FLOAT fields don't display their proper display 
lengths in max_display_length(). This is hard-coded as 53 for 
DOUBLE and 24 for FLOAT. Now changed to instead return the 
field_length.

#2: Type holders for temporary tables do not preserve the 
max_length of the Item's from which they are created, and is 
instead reverted to the 53 and 24 from above. This causes 
*all* fields to get non-fixed significant digits.

#3: AVG function does not update max_length (display length)
when updating number of decimals.

#4: The function that switches to non-fixed number of 
significant digits should use DBL_DIG + 2 or FLT_DIG + 2 as 
cut-off values (Since fixed precision does not use the 'e' 
notation)

Of these points, #1 is the controversial one, but this 
change is preferred and has been cleared with Monty. The 
function causes quite a few unit tests to blow up and they had
to b changed, but each one is annotated and motivated. We 
frequently see the magical 53 and 24 give way to more relevant
numbers.


mysql-test/r/create.result:
  bug#24791
  
  changed test result
  
  With the changes made for FLOAT and DOUBLE, the original display
  lengths are now preserved.
mysql-test/r/temp_table.result:
  bug#24791
  
  changed test resullt
  
  Test case added
mysql-test/r/type_float.result:
  bug#24791
  
  changed test result
  
  delta 1: field was originally declared as DOUBLE with no display
  length, so the hardware maximum is chosen rather than 53.
  
  delta 2: fields exceed the maximum precision and thus switch to
  non-fixed significant digits
  
  delta 3: Same as above, number of decmals and significant digits
  was not specified when t3 was created.
mysql-test/t/temp_table.test:
  bug#24791
  
  Test case
sql/field.h:
  bug#24791
  
  The method max_display_length is reimplemented as
  
  uint32 max_display_length() { return field_length; }
  
  in Field_double and Field_float. Since all subclasses of 
  Field_real now have the same implementation of this method, the
  implementation has been moved up the hierarchy to Field_real.
sql/item.cc:
  bug#24791
  
  We switch to a non-fixed number of significant digits
  (by setting decimals=NOT_FIXED_DECIMAL) if the calculated 
  display length is greater than the display length of a value 
  with the maximum precision. These values differ for double and 
  float, obviously.
sql/item_sum.cc:
  bug#24791
  
  We must increase the display length accordinly whenever we 
  change number of decimal places.

  failing in recognizing these commands is not fatal error
  anymore.

d8d57c77b1 Bug#22436 Four tests require "innodb" to be configured, fail in "classic" build 
- Disable warnings when creating the "innodb" tables if it works anyway.
 - Move test that are really innodb dependent to innodb_mysql 


mysql-test/r/create.result:
  Move the innodb dependent test to innodb_mysql.test
mysql-test/r/innodb_mysql.result:
  Move the innodb dependent test to innodb_mysql.test
mysql-test/t/create.test:
  Move the innodb dependent test to innodb_mysql.test
mysql-test/t/innodb_mysql.test:
  Move the innodb dependent test to innodb_mysql.test
mysql-test/t/lock_multi.test:
  Disable warnings while creating the innodb table. If innodb is not available, the table will be created with default engine and thus create a warning. Regardless of this, test output should be the same.
mysql-test/t/sp.test:
  Disable warnings while creating the innodb table. If innodb is not available, the table will be created with default engine and thus create a warning. Regardless of this, test output should be the same.
mysql-test/t/view.test:
  Disable warnings while creating the innodb table. If innodb is not available, the table will be created with default engine and thus create a warning. Regardless of this, test output should be the same.
