6230c2e296 Fix test that did not work in out-of-source build .
There are 2 different share directories, one if builddir/share (with compiled errmsg.sys) 
and another one is $sourcedir/share and contains some /charsets/*.xml files.
second one should be refered to  as MYSQL_CHARSETSDIR and  MYSQL_SHAREDIR  $builddir/share

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.

74a853e40b Merge next-mr -> next-4284.
Post merge fixes. In sys_vars tests suite, whenever we use LOCK TABLE WRITE,
adjust to lock the subject table indirecty via a view, to ensure that
there the desired lock conflict in thr_lock.c is still taking place.
If locked directly in LOCK TABLES list, thr_lock.c does not get
involved.
Adjust the thread wait state names in information_schema.processlist.

  BUG#46364 MyISAM transbuffer problems (NTM problem)
        
  It is well-known that due to concurrency issues, a slave can become
  inconsistent when a transaction contains updates to both transaction and
  non-transactional tables.
                      
  In a nutshell, the current code-base tries to preserve causality among the
  statements by writing non-transactional statements to the txn-cache which
  is flushed upon commit. However, modifications done to non-transactional
  tables on behalf of a transaction become immediately visible to other
  connections but may not immediately get into the binary log and therefore
  consistency may be broken.
              
  In general, it is impossible to automatically detect causality/dependency
  among statements by just analyzing the statements sent to the server. This
  happen because dependency may be hidden in the application code and it is
  necessary to know a priori all the statements processed in the context of
  a transaction such as in a procedure. Moreover, even for the few cases that
  we could automatically address in the server, the computation effort
  required could make the approach infeasible.
              
  So, in this patch we introduce the option
        - "--binlog-direct-non-transactional-updates" that can be used to bypass
        the current behavior in order to write directly to binary log statements
        that change non-transactional tables.
  
  Besides, it is used to enable the WL#2687 which is disabled by default.

4009bf1a15 BUG#46364 MyISAM transbuffer problems (NTM problem)
It is well-known that due to concurrency issues, a slave can become
inconsistent when a transaction contains updates to both transaction and
non-transactional tables.
                    
In a nutshell, the current code-base tries to preserve causality among the
statements by writing non-transactional statements to the txn-cache which
is flushed upon commit. However, modifications done to non-transactional
tables on behalf of a transaction become immediately visible to other
connections but may not immediately get into the binary log and therefore
consistency may be broken.
            
In general, it is impossible to automatically detect causality/dependency
among statements by just analyzing the statements sent to the server. This
happen because dependency may be hidden in the application code and it is
necessary to know a priori all the statements processed in the context of
a transaction such as in a procedure. Moreover, even for the few cases that
we could automatically address in the server, the computation effort
required could make the approach infeasible.
            
So, in this patch we introduce the option
      - "--binlog-direct-non-transactional-updates" that can be used to bypass
      the current behavior in order to write directly to binary log statements
      that change non-transactional tables.

Besides, it is used to enable the WL#2687 which is disabled by default.

mysql-test/extra/rpl_tests/rpl_binlog_max_cache_size.test:
  Changes the result set as the STMT mode behaves as both the ROW and MIXED modes and as such uses the non-trx-cache and takes longer to fill the trx-cache up and trigger an error.
mysql-test/extra/rpl_tests/rpl_implicit_commit_binlog.test:
  Changes the result set as the STMT mode behaves as both the ROW and MIXED modes and as such uses the non-trx-cache. It also fixes comments.
mysql-test/extra/rpl_tests/rpl_mixing_engines.test:
  The STMT mode is unsafe when mixed-statements are executed thus making slaves to go out of sync. For that reason, it checks consistency if not in STMT mode.
mysql-test/include/default_mysqld.cnf:
  Makes binlog-direct-non-transactional-updates "TRUE" by default in the test
  cases.
mysql-test/r/mysqld--help-notwin.result:
  Updates the result file with the new option.
mysql-test/r/mysqld--help-win.result:
  Updates the result file with the new option.
mysql-test/suite/binlog/r/binlog_multi_engine.result:
  Updates the result file because non-trx-changes are written ahead of the
  transaction.
mysql-test/suite/binlog/r/binlog_switch_inside_trans.result:
  Verifies if the user cannot change the opion binlog_direct_non_transactional_updates
  within a transaction or a procedure/function/trigger.

sql/log.h:
  Changes the signature of some functions by adding the modifier "const" to the thd parameter. Specifically, the following functions are changed: 
          bool trans_has_updated_trans_table(const THD* thd);
          bool stmt_has_updated_trans_table(const THD *thd);
          bool use_trans_cache(const THD*, bool is_transactional);

message:
Bug#989: If DROP TABLE while there's an active transaction, wrong binlog order
WL#4284: Transactional DDL locking

Currently the MySQL server does not keep metadata locks on
schema objects for the duration of a transaction, thus failing
to guarantee the integrity of the schema objects being used
during the transaction and to protect then from concurrent
DDL operations. This also poses a problem for replication as
a DDL operation might be replicated even thought there are
active transactions using the object being modified.

The solution is to defer the release of metadata locks until
a active transaction is either committed or rolled back. This
prevents other statements from modifying the table for the
entire duration of the transaction. This provides commitment
ordering for guaranteeing serializability across multiple
transactions.

- Incompatible change:

If MySQL's metadata locking system encounters a lock conflict,
the usual schema is to use the try and back-off technique to
avoid deadlocks -- this schema consists in releasing all locks
and trying to acquire them all in one go.

But in a transactional context this algorithm can't be utilized
as its not possible to release locks acquired during the course
of the transaction without breaking the transaction commitments.
To avoid deadlocks in this case, the ER_LOCK_DEADLOCK will be
returned if a lock conflict is encountered during a transaction.

Let's consider an example:

A transaction has two statements that modify table t1, then table
t2, and then commits. The first statement of the transaction will
acquire a shared metadata lock on table t1, and it will be kept
utill COMMIT to ensure serializability.

At the moment when the second statement attempts to acquire a
shared metadata lock on t2, a concurrent ALTER or DROP statement
might have locked t2 exclusively. The prescription of the current
locking protocol is that the acquirer of the shared lock backs off
-- gives up all his current locks and retries. This implies that
the entire multi-statement transaction has to be rolled back.

- Incompatible change:

FLUSH commands such as FLUSH PRIVILEGES and FLUSH TABLES WITH READ
LOCK won't cause locked tables to be implicitly unlocked anymore.

  Add a test case for Bug#989/WL#4284.
mysql-test/t/not_embedded_server.test:
  Add a test case for Bug#989/WL#4284.
mysql-test/t/partition_innodb_semi_consistent.test:

  on metadata locks.
mysql-test/t/partition_sync.test:

  temporary savepoint, taken at the beginning of PREPARE,
  and released at the end. Thus PREPARE does not effect
  what locks a transaction owns.
mysql-test/t/read_only_innodb.test:
  Fix test case to reflect the fact that transactions now hold
  metadata locks for the duration of a transaction 
  (Bug#989/WL#4284).
  
  Wait for the read_only statement to actually flush tables before
  sending other concurrent statements that depend on its state.
mysql-test/t/xa.test:
  Fix test case to reflect the fact that transactions now hold
  metadata locks for the duration of a transaction 
  (Bug#989/WL#4284).
sql/ha_ndbcluster_binlog.cc:
  Backport bits of changes of ha_ndbcluster_binlog.cc
  from 6.0, to fix the failing binlog test suite with
  WL#4284. WL#4284 implementation does not work
  with 5.1 implementation of ndbcluster binlog index.
sql/log_event.cc:
  Release metadata locks after issuing a commit.
sql/mdl.cc:
  Style changes (WL#4284).
sql/mysql_priv.h:
  Rename parameter to match the name used in the definition (WL#4284).
sql/rpl_injector.cc:
  Release metadata locks on commit (WL#4284).
sql/rpl_rli.cc:
  Remove assert made meaningless, metadata locks are released
  at the end of the transaction.
sql/set_var.cc:
  Close tables and release locks if autocommit mode is set.
sql/slave.cc:
  Release metadata locks after a rollback.
sql/sql_acl.cc:
  Don't implicitly unlock locked tables. Issue a implicit commit
  at the end and unlock tables.
sql/sql_base.cc:
  Defer the release of metadata locks when closing tables
  if not required to.
  Issue a deadlock error if the locking protocol requires
  that a transaction re-acquire its locks.
  
  Release metadata locks when closing tables for reopen.
sql/sql_class.cc:
  Release metadata locks if the thread is killed.
sql/sql_parse.cc:
  Release metadata locks after implicitly committing a active
  transaction, or after explicit commits or rollbacks.
sql/sql_plugin.cc:
  
  Allocate MDL request on the stack as the use of the table
  is contained within the function. It will be removed from
  the context once close_thread_tables is called at the end
  of the function.
sql/sql_prepare.cc:
  The problem is that the prepare phase of the CREATE TABLE
  statement takes a exclusive metadata lock lock and this can
  cause a self-deadlock the thread already holds a shared lock
  on the table being that should be created.
  
  The solution is to make the prepare phase take a shared
  metadata lock when preparing a CREATE TABLE statement. The
  execution of the statement will still acquire a exclusive
  lock, but won't cause any problem as it issues a implicit
  commit.
  
  After some discussions with stakeholders it has been decided that
  metadata locks acquired during a PREPARE statement must be released
  once the statement is prepared even if it is prepared within a multi
  statement transaction.
sql/sql_servers.cc:
  Don't implicitly unlock locked tables. Issue a implicit commit
  at the end and unlock tables.
sql/sql_table.cc:
  Close table and release metadata locks after a admin operation.
sql/table.h:
  The problem is that the prepare phase of the CREATE TABLE
  statement takes a exclusive metadata lock lock and this can
  cause a self-deadlock the thread already holds a shared lock
  on the table being that should be created.
  
  The solution is to make the prepare phase take a shared
  metadata lock when preparing a CREATE TABLE statement. The
  execution of the statement will still acquire a exclusive
  lock, but won't cause any problem as it issues a implicit
  commit.
sql/transaction.cc:
  Release metadata locks after the implicitly committed due
  to a new transaction being started. Also, release metadata
  locks acquired after a savepoint if the transaction is rolled
  back to the save point.
  
  The problem is that in some cases transaction-long metadata locks
  could be released before the transaction was committed. This could
  happen when a active transaction was ended by a "START TRANSACTION"
  or "BEGIN" statement, in which case the metadata locks would be
  released before the actual commit of the active transaction.
  
  The solution is to defer the release of metadata locks to after the
  transaction has been implicitly committed. No test case is provided
  as the effort to provide one is too disproportional to the size of
  the fix.

message:
  Bug#36785: Wrong error message when group_concat() exceeds max length

  The problem is that when ER_CUT_VALUE_GROUP_CONCAT is elevated
  to a error, the message does not get updated with the number of
  cut lines when group_concat() exceeds max length.

  The solution is to modify the warning message to be more meaningful
  by giving the number of the line that was cut and to issue the warning
  for each line that is cut. This approach is inline with how other
  per-row truncated data warnings are issued avoids violating the warning
  internal interface.

mysql-test/suite/sys_vars/r/group_concat_max_len_func.result:
  Update result to reflect the new warning message
sql/share/errmsg.txt:
  Update warning message ER_CUT_VALUE_GROUP_CONCAT.
