Fix for bug #46947 "Embedded SELECT without FOR UPDATE is
causing a lock", with after-review fixes.

SELECT statements with subqueries referencing InnoDB tables
were acquiring shared locks on rows in these tables when they
were executed in REPEATABLE-READ mode and with statement or
mixed mode binary logging turned on.

This was a regression which were introduced when fixing
bug 39843.

The problem was that for tables belonging to subqueries
parser set TL_READ_DEFAULT as a lock type. In cases when
statement/mixed binary logging at open_tables() time this
type of lock was converted to TL_READ_NO_INSERT lock at
open_tables() time and caused InnoDB engine to acquire
shared locks on reads from these tables. Although in some
cases such behavior was correct (e.g. for subqueries in
DELETE) in case of SELECT it has caused unnecessary locking.

This patch tries to solve this problem by rethinking our
approach to how we handle locking for SELECT and subqueries.
Now we always set TL_READ_DEFAULT lock type for all cases
when we read data. When at open_tables() time this lock
is interpreted as TL_READ_NO_INSERT or TL_READ depending
on whether this statement as a whole or call to function
which uses particular table should be written to the
binary log or not (if yes then statement should be properly
serialized with concurrent statements and stronger lock
should be acquired).

Test coverage is added for both InnoDB and MyISAM.

This patch introduces an "incompatible" change in locking
scheme for subqueries used in SELECT ... FOR UPDATE and
SELECT .. IN SHARE MODE.
In 4.1 the server would use a snapshot InnoDB read for 
subqueries in SELECT FOR UPDATE and SELECT .. IN SHARE MODE
statements, regardless of whether the binary log is on or off.
If the user required a different type of read (i.e. locking read),
he/she could request so explicitly by providing FOR UPDATE/IN SHARE MODE
clause for each individual subquery.
On of the patches for 5.0 broke this behaviour (which was not documented
or tested), and started to use locking reads fora all subqueries in SELECT ... 
FOR UPDATE/IN SHARE MODE. This patch restored 4.1 behaviour.

sql/log_event.cc:
  Since LEX::lock_option member was removed we no longer can
  rely on its value in Load_log_event::print_query() to
  determine that log event correponds to LOAD DATA CONCURRENT
  statement (this was not correct in all situations anyway).
  A new Load_log_event's member was introduced as a replacement.
  It is initialized at event object construction time and
  explicitly indicates whether LOAD DATA was concurrent.
sql/log_event.h:

  statement (this was not correct in all situations anyway).
  A new Load_log_event's member was introduced as a replacement.
  It is initialized at event object construction time and
  explicitly indicates whether LOAD DATA was concurrent.
sql/sp_head.cc:
  sp_head::reset_lex():
    Before parsing substatement reset part of parser state
    which needs this (e.g. set Yacc_state::m_lock_type to
    default value).
sql/sql_acl.cc:
  Since LEX::reset_n_backup_query_tables_list() now also
  resets LEX::sql_command member (as it became part of
  Query_tables_list class) we have to restore it in cases
  when while working with proxy Query_table_list we assume
  that LEX::sql_command still corresponds to original SQL
  command being executed (for example, when we are logging
  statement to the binary log while having Query_tables_list
  reset and backed up).
sql/sql_base.cc:
  Changed read_lock_type_for_table() to return a weak TL_READ
  type of lock in cases when we are executing statement which
  won't update tables directly and table doesn't belong to
  statement's prelocking list and thus can't be used by a
  stored function. It is OK to do so since in this case table
  won't be used by statement or function call which will be
  written to the binary log, so serializability requirements
  for it can be relaxed.
  One of results from this change is that SELECTs on InnoDB
  tables no longer takes shared row locks for tables which
  are used in subqueries (i.e. bug #46947 is fixed).
  Another result is that for similar SELECTs on MyISAM tables
  concurrent inserts are allowed.
  In order to implement this change signature of
  read_lock_type_for_table() function was changed to take
  pointers to Query_tables_list and TABLE_LIST objects.
sql/sql_base.h:
  - Function read_lock_type_for_table() now takes pointers
    to Query_tables_list and TABLE_LIST elements as its
    arguments since to correctly determine lock type it needs
    to know what statement is being performed and whether table
    element for which lock type to be determined belongs to
    prelocking list.
sql/sql_lex.cc:
  - Removed LEX::lock_option and st_select_lex::lock_option
    members. Places in parser that were using them now use
    Yacc_state::m_lock_type instead.
  - To emphasize that LEX::sql_command member is used during
    process of opening and locking of tables it was moved to
    Query_tables_list class. It is now reset by
    Query_tables_list::reset_query_tables_list() method.
sql/sql_lex.h:
  - Removed st_select_lex::lock_option member as there is no
    real need for per-SELECT lock type (HIGH_PRIORITY option
    should apply to the whole statement. FOR UPDATE/LOCK IN
    SHARE MODE clauses can be handled without this member).
    The main effect which was achieved by introduction of this
    member, i.e. using TL_READ_DEFAULT lock type for
    subqueries, is now achieved by setting LEX::lock_option
    (or rather its replacement - Yacc_state::m_lock_type) to
    TL_READ_DEFAULT in almost all cases.
  - To emphasize that LEX::sql_command member is used during
    process of opening and locking of tables it was moved to
    Query_tables_list class.
  - Replaced LEX::lock_option with Yacc_state::m_lock_type
    in order to emphasize that this value is relevant only
    during parsing. Unlike for LEX::lock_option the default
    value for Yacc_state::m_lock_type is TL_READ_DEFAULT.
    Note that for cases when it is OK to take a "weak" read
    lock (e.g. simple SELECT) this lock type will be converted
    to TL_READ at open_tables() time. So this change won't
    cause negative change in behavior for such statements.
    OTOH this change ensures that, for example, for SELECTs
    which are used in stored functions TL_READ_NO_INSERT lock
    is taken when necessary and as result calls to such stored
    functions can be written to the binary log with correct
    serialization.
sql/sql_load.cc:
  Load_log_event constructor now requires a parameter that
  indicates whether LOAD DATA is concurrent.
sql/sql_parse.cc:
  LEX::lock_option was replaced with Yacc_state::m_lock_type.
  And instead of resetting the latter implicitly in
  mysql_init_multi_delete() we do it explicitly in the
  places in parser which call this function.
sql/sql_priv.h:
  - To be able more easily distinguish high-priority SELECTs
    in st_select_lex::print() method added flag for
    HIGH_PRIORITY option.
sql/sql_select.cc:
  Changed code not to rely on LEX::lock_option to determine
  that it is high-priority SELECT. It was replaced with
  Yacc_state::m_lock_type which is accessible only at
  parse time. So instead of LEX::lock_option we now rely
  on a newly introduced flag for st_select_lex::options -
  SELECT_HIGH_PRIORITY.
sql/sql_show.cc:
  Since LEX::reset_n_backup_query_tables_list() now also
  resets LEX::sql_command member (as it became part of
  Query_tables_list class) we have to restore it in cases
  when while working with proxy Query_table_list we assume
  that LEX::sql_command still corresponds to original SQL
  command being executed.
sql/sql_table.cc:
  Since LEX::reset_query_tables_list() now also resets
  LEX::sql_command member (as it became part of
  Query_tables_list class) we have to restore value of this
  member when this method is called by mysql_admin_table(),
  to make this code safe for re-execution.
sql/sql_trigger.cc:
  Since LEX::reset_n_backup_query_tables_list() now also
  resets LEX::sql_command member (as it became part of
  Query_tables_list class) we have to restore it in cases
  when while working with proxy Query_table_list we assume
  that LEX::sql_command still corresponds to original SQL
  command being executed (for example, when we are logging
  statement to the binary log while having Query_tables_list
  reset and backed up).
sql/sql_update.cc:
  Function read_lock_type_for_table() now takes pointers
  to Query_tables_list and TABLE_LIST elements as its
  arguments since to correctly determine lock type it needs
  to know what statement is being performed and whether table
  element for which lock type to be determined belongs to
  prelocking list.
sql/sql_yacc.yy:
  - Removed st_select_lex::lock_option member as there is no
    real need for per-SELECT lock type (HIGH_PRIORITY option
    should apply to the whole statement. FOR UPDATE/LOCK IN
    SHARE MODE clauses can be handled without this member).
    The main effect which was achieved by introduction of this
    member, i.e. using TL_READ_DEFAULT lock type for
    subqueries, is now achieved by setting LEX::lock_option
    (or rather its replacement - Yacc_state::m_lock_type) to
    TL_READ_DEFAULT in almost all cases.
  - Replaced LEX::lock_option with Yacc_state::m_lock_type
    in order to emphasize that this value is relevant only
    during parsing. Unlike for LEX::lock_option the default
    value for Yacc_state::m_lock_type is TL_READ_DEFAULT.
    Note that for cases when it is OK to take a "weak" read
    lock (e.g. simple SELECT) this lock type will be converted
    to TL_READ at open_tables() time. So this change won't
    cause negative change in behavior for such statements.
    OTOH this change ensures that, for example, for SELECTs
    which are used in stored functions TL_READ_NO_INSERT lock
    is taken when necessary and as result calls to such stored
    functions can be written to the binary log with correct
    serialization.
  - To be able more easily distinguish high-priority SELECTs
    in st_select_lex::print() method we now use new flag
    in st_select_lex::options bit-field.

Problem: ALTER TABLE ADD INDEX may lead to table copying if there's
numeric field(s) with non-default display width modificator specified.

20f5c421e7 BUG#51894 Replication failure with SBR on DROP TEMPORARY TABLE inside a
transaction
BUG#52616 Temp table prevents switch binlog format from STATEMENT to ROW

Before the WL#2687 and BUG#46364, every non-transactional change that happened
after a transactional change was written to trx-cache and flushed upon
committing the transaction. WL#2687 and BUG#46364 changed this behavior and
non-transactional changes are now written to the binary log upon committing
the statement.

A binary log event is identified as transactional or non-transactional through
a flag in the Log_event which is set taking into account the underlie storage
engine on what it is stems from. In the current bug, this flag was not being
set properly when the DROP TEMPORARY TABLE was executed.

However, while fixing this bug we figured out that changes to temporary tables
should be always written to the trx-cache if there is an on-going transaction.
Otherwise, binlog events in the reversed order would be produced.

Regarding concurrency, keeping changes to temporary tables in the trx-cache is
also safe as temporary tables are only visible to the owner connection.

In this patch, we classify the following statements as unsafe:
   1 - INSERT INTO t_myisam SELECT * FROM t_myisam_temp

   2 - INSERT INTO t_myisam_temp SELECT * FROM t_myisam

   3 - CREATE TEMPORARY TABLE t_myisam_temp SELECT * FROM t_myisam

On the other hand, the following statements are classified as safe:

   1 - INSERT INTO t_innodb SELECT * FROM t_myisam_temp

   2 - INSERT INTO t_myisam_temp SELECT * FROM t_innodb

The patch also guarantees that transactions that have a DROP TEMPORARY are
always written to the binary log regardless of the mode and the outcome:
commit or rollback. In particular, the DROP TEMPORARY is extended with the
IF EXISTS clause when the current statement logging format is set to row.

Finally, the patch allows to switch from STATEMENT to MIXED/ROW when there
are temporary tables but the contrary is not possible.

  It allows to switch from STATEMENT to MIXED/ROW when there are temporary
  tables but the contrary is not possible.
sql/sql_table.cc:
  Fixed the case that a DROP/DROP TEMPORARY that affects a temporary table in MIXED
  mode is written as a DROP TEMPORARY TABLE IF EXISTS because the table may not exist in the slave and due to the IF EXISTS token an error will never happen
  while processing the statement in the slave.
  
  Removed a function that was not being used.

cf8df9ca44 Bug #47459 Assertion in Diagnostics_area::set_eof_status on OPTIMIZE TABLE
This assertion could be triggered during execution of OPTIMIZE TABLE for
InnoDB tables. As part of optimize for InnoDB tables, the table is recreated
and then opened again. If the reopen failed for any reason, the assertion
would be triggered. This could for example be caused by a concurrent DROP
TABLE executed by a different connection. The reason for the assertion was
that any failures during reopening were ignored.

This patch fixes the problem by making sure that the result of reopening the
table is checked and that any error messages are sent to the client.

Test case added to innodb_mysql_sync.test.

47906997c7 Bug#51851: Server with SBR locks mutex twice on LOAD DATA
into partitioned MyISAM table

Problem was that the ha_data structure was introduced in 5.1
and only used for partitioning first, but with the intention
of be of use for others engines as well, and when used by other
engines it would clash if it also was partitioned.

Solution is to move the partitioning specific data to a separate
structure, with its own mutex (which is used for auto_increment).

Also did rename PARTITION_INFO to PARTITION_STATS since there
already exist a class named partition_info, also cleaned up
some related variables.

ae49d9710b Bug #49838: DROP INDEX and ADD UNIQUE INDEX for same index may corrupt
definition at engine

If a single ALTER TABLE contains both DROP INDEX and ADD INDEX using 
the same index name (a.k.a. index modification) we need to disable 
in-place alter table because we can't ask the storage engine to have 
two copies of the index with the same name even temporarily (if we 
first do the ADD INDEX and then DROP INDEX) and we can't modify 
indexes that are needed by e.g. foreign keys if we first do 
DROP INDEX and then ADD INDEX.
Fixed the problem by disabling in-place ALTER TABLE for these cases.

09b7a0d115 A post-review fix for type-aware metadata locks.
DDL no longer aborts mysql_lock_tables(), and hence
we no longer need to support need_reopen flag of this
call. 
Remove the flag, and all the code in the server
that was responsible for handling the case when
it was set. This allowed to simplify: 
open_and_lock_tables_derived(), the delayed thread,
multi-update.

Rename MYSQL_LOCK_IGNORE_FLUSH to MYSQL_OPEN_IGNORE_FLUSH,
since we now only support this flag in open_table().

Rename MYSQL_LOCK_PERF_SCHEMA to MYSQL_LOCK_LOG_TABLE,
to avoid confusion.

Move the wait for the global read lock for cases
when we do updates in SELECT f1() or DO (UPDATE) to 
open_table() from mysql_lock_tables(). When waiting
for the read lock, we could raise need_reopen flag,
which is no longer present in mysql_lock_tables().
Since the block responsible for waiting for GRL
was moved, MYSQL_LOCK_IGNORE_GLOBAL_READ_LOCK
was renamed to MYSQL_OPEN_IGNORE_GLOBAL_READ_LOCK.


mysql-test/r/mdl_sync.result:
  Update test results (see comments for mdl_sync.test).
mysql-test/t/mdl_sync.test:
  Update tests: an abort mysql_lock_tables() called for an

sql/lock.cc:

  Update comments.
sql/log_event_old.cc:

  out parameter of mysql_lock_tables().
sql/mysql_priv.h:
  Update open and lock tables flag names.
sql/share/errmsg-utf8.txt:
  Add a new error message to report when
  thr_multi_lock() is aborted.
sql/sql_base.cc:
  Update comments. Rename MYSQL_LOCK_IGNORE_FLUSH
  to MYSQL_OPEN_IGNORE_FLUSH.
sql/sql_class.h:
  Remove unused code.
sql/sql_db.cc:
  Remove an unused bit of code.
sql/sql_handler.cc:
  For backward compatibility, we still want to back off and
  retry when a call to mysql_lock_tables() is aborted
  from within an SQL HANDLER. Write an internal error
  handler to support the case.
sql/sql_insert.cc:
  Call mysql_lock_tables() no longer has need_reopen
  out parameter. Simplify the code by removing 
  the crud that took care of it.
  MYSQL_LOCK_IGNORE_FLUSH is now only supported by
  open_tables().
sql/sql_show.cc:
  Rename MYSQL_LOCK_IGNORE_FLUSH to MYSQL_OPEN_IGNORE_FLUSH
sql/sql_table.cc:
  Remove an unused parameter.
sql/sql_update.cc:
  Remove the need_reopen loop from multi-update.
  We no also longer need to cleanup the parse tree in case
  when mysql_lock_tables() is aborted and thus an infinite
  source of multi-update bugs is gone.
sql/tztime.cc:
  Rename MYSQL_LOCK_IGNORE_FLUSH to MYSQL_OPEN_IGNORE_FLUSH,
  since from now on this flag is only supported by open_table().

e60ef89317 Followup to Bug#45225 Locking: hang if drop table with no timeout
This patch prevents system threads and system table accesses from
using user-specified values for "lock_wait_timeout". Instead all
such accesses are done using the default value (1 year).

This prevents background tasks (such as replication, events, 
accessing stored function definitions, logging, reading time-zone
information, etc.) from failing in cases where the global value
of "lock_wait_timeout" is set very low.

The patch also simplifies the open tables API. Rather than adding
another convenience function for opening and locking system tables,
this patch removes most of the existing convenience functions for
open_and_lock_tables_derived(). Before, open_and_lock_tables() was
a convenience function that enforced derived tables handling, while
open_and_lock_tables_derived() was the main function where derived
tables handling was optional. Now, this convencience function is
gone and the main function is renamed to open_and_lock_tables(). 

No test case added as it would have required the use of --sleep to
check that system threads and system tables have a different timeout
value from the user-specified "lock_wait_timeout" system variable.

203793514d Bug#50574 5.5.x allows spatial indexes on non-spatial columns,
causing crashes!

Adding a SPATIAL INDEX on a non-geometrical column caused a
segmentation fault when the table was subsequently 
inserted into.
      
A test was added in mysql_prepare_create_table to explicitly
check whether non-geometrical columns are used in a
spatial index, and throw an error if so.


mysql-test/t/gis.test:
  Added test cases to verify that only geometrical
  columns can get a spatial index.
          
  In addition, verify that only a single geom.
  column can participate in a spatial index.

93cd02bc82 Bug#50542 5.5.x doesn't check length of key prefixes:
corruption and crash results
      
An index creation statement where the index key
is larger/wider than the column it references 
should throw an error.
      
A statement like:
  CREATE TABLE t1 (a CHAR(1), PRIMARY KEY (A(255)))
did not error, but a segmentation fault followed when
an insertion was attempted on the table
      
The partial key validiation clause has been 
restructured to (hopefully) better document which
uses of partial keys are valid.

3d6a89e792 Bug #45225 Locking: hang if drop table with no timeout
This patch introduces timeouts for metadata locks. 

The timeout is specified in seconds using the new dynamic system 
variable  "lock_wait_timeout" which has both GLOBAL and SESSION
scopes. Allowed values range from 1 to 31536000 seconds (= 1 year). 
The default value is 1 year.

The new server parameter "lock-wait-timeout" can be used to set
the default value parameter upon server startup.

"lock_wait_timeout" applies to all statements that use metadata locks.
These include DML and DDL operations on tables, views, stored procedures
and stored functions. They also include LOCK TABLES, FLUSH TABLES WITH
READ LOCK and HANDLER statements.

The patch also changes thr_lock.c code (table data locks used by MyISAM
and other simplistic engines) to use the same system variable.
InnoDB row locks are unaffected.

One exception to the handling of the "lock_wait_timeout" variable
is delayed inserts. All delayed inserts are executed with a timeout
of 1 year regardless of the setting for the global variable. As the
connection issuing the delayed insert gets no notification of 
delayed insert timeouts, we want to avoid unnecessary timeouts.

It's important to note that the timeout value is used for each lock
acquired and that one statement can take more than one lock.
A statement can therefore block for longer than the lock_wait_timeout 
value before reporting a timeout error. When lock timeout occurs, 
ER_LOCK_WAIT_TIMEOUT is reported.

Test case added to lock_multi.test.

  Added macros for comparing two timespec structs.

d77e3cde5f When one does a drop table, the indexes are not flushed to disk before drop anymore (with MyISAM/Maria)
myisam-recover options changed from OFF to 'DEFAULT' to get less change of data loss when using MyISAM.
(The disadvantage is that changed MyISAM tables will be checked at access time; Use --myisam-recover=OFF for old behavior)
Don't call extra(HA_EXTRA_FORCE_REOPEN) in ALTER TABLE if table is locked as this will mark table as crashed!
Added assert to detect if we accidently would use MyISAM versioning in MySQL

dca6700620 Bug#50201: Server crashes in explain_filename on an InnoDB partitioned table
Problem was that in mysql-trunk the ER() macro is now dependent on current_thd
and the innodb monitor thread has no binding to that thd object. This cause 
the crash because of bad derefencing.

Solution was to add a new macro which take the thd as an argument (which the innodb
thread uses for the call).

(Updated according to reviewers comments, i.e. added ER_THD_OR_DEFAULT and
moved test to suite parts.)

  Note that the innodb monitor thread only runs every 15 seconds, so this
  test will take at least 15 seconds, so I have moved it to the parts suite.

Cherry-pick a fix Bug#37148 from next-mr, to preserve
file ids of the added files, and ensure that all the necessary
changes have been pulled.

Since initially Bug#37148 was null-merged into 6.0,
the changeset that is now being cherry-picked was likewise
null merged into next-4284.

Now that Bug#37148 has been reapplied to 6.0, try to make
it work with next-4284. This is also necessary to be able
to pull other changes from 5.1-rep into next-4284.

To resolve the merge issues use this changeset applied
