stat structure (from <sys/stat.h>) is conditionally defined
to have different layout and size depending on the defined macros.
The correct macro is defined in my_config.h, which means it MUST be
included first (or, at least before <features.h> - so, practically,
before including any system headers).
after revision 4363 (fixes for MDEV-6661 and MDEV-6666).
Fixing a wrong assumption in ha_connect.cc that strings
returned from val_str() are always 0-terminated.
The reason for the failure was a bug in an include file on debian that causes 'struct stat'
to have different sized depending on the environment.
This patch fixes so that we always include my_global.h or my_config.h before we include any other files.
Other things:
- Removed #include <my_global.h> in some include files; Better to always do this at the top level to have as few
"always-include-this-file-first' files as possible.
- Removed usage of some include files that where already included by my_global.h or by other files.

FROM A FUNCTION
Scenario:
In a stored procedure, CREATE TABLE statement is not allowed. But an
exception is provided for CREATE TEMPORARY TABLE. We can create a temporary
table in a stored procedure.
Let there be two stored functions f1 and f2 and two stored procedures p1 and
p2. Their properties are as follows:
. stored function f1() calls stored procedure p1().
. stored function f2() calls stored procedure p2().
. stored procedure p1() creates temporary table t1.
. stored procedure p2() does DML on t1.
Consider the following situation:
1. Autocommit mode is on.
2. select f1()
3. select f2()
Step 2: In this step, t1 would be created via p1(). A table level transaction
lock would have been taken. The ::external_lock() would not have been called
on this table. At the end of step 2, because of autocommit mode on, this table
level lock will be released.
Step 3: When we execute DML on table t1 via p2() we have two problems:
Problem 1:
The function ha_innobase::external_lock() would have been called but since
it is a select query no table level locks would have been taken. Hence the
following assert will fail:
ut_ad(lock_table_has(thr_get_trx(thr), index->table, LOCK_IX));
Solution:
The solution would be to identify this situation and take a table level lock
and use the proper lock type prebuilt->select_lock_type = LOCK_X for DML
operations.
Problem 2:
Another problem is that in step 3, ha_innobase::open() is never called on
the table t1.
Solution:
The solution would be to identify this situation and call re-init the handler
of table t1.

Problem:
Creation of a table fails when innodb_strict_mode is enabled, but the same
table is created without any warning when innodb_strict_mode is enabled.
Solution:
If creation of a table fails with an error when innodb_strict_mode is
enabled, it must issue a warning when innodb_strict_mode is disabled.

- after a change in 5.6.20, tests with big blobs require bigger
innodb_log_file_size value;
- innobase relay was running with the default InnoDB (XtraDB)
The problem was that my_hash_sort didn't properly delete end-space characters properly, so strings that should compare
identically was seen as different strings. (Space was handled correctly, but not NBSP)
This caused duplicate key errors when a heap table was converted to Aria as part of overflow in group by.
Fixed by removing all characters that compares as end space when creating a hash.
Other things:
- Fixed that --sorted_results also works for errors in mysqltest.
- Speed up hash by not comparing strings that has different hash.
- Speed up many my_hash_sort functions by using registers to calculate hash instead of pointers.
This was previously done for some functions, but not for all.
- Made a macro of the hash function, to simplify code and to be able to experiment with new hash functions.

file trx0trx.ic line 60
Problem was that trx might have not been started when we enter release
savepoint, this can happen when trx with savepoint is already aborted
or when we try to release non-existing savepoint.
CHECK.
Analysis:
----------
Issue here is, while creating or altering the InnoDB table,
if the foreign key defined on the table references a parent
table on which the user has no access privileges then the
table is created without reporting any error.
Currently the privilege level REFERENCES_ACL is unused
and is not used for access evaluation while creating the
table with a foreign key constraint or adding the foreign
key constraint to a table. But when no privileges are granted
to user then also access evaluation on parent table is ignored.
Fix:
---------
For DMLs, irrelevant of the fact, support does not want any
changes to avoid permission checks on every operation.
So, as a fix, added a function "check_fk_parent_table_access"
to check whether any of the SELECT_ACL, INSERT_ACL, UDPATE_ACL,
DELETE_ACL or REFERENCE_ACL privileges are granted for user
at table level. If none of them is granted then error is reported.
This function is called during the table creation and alter
operation.
* handler::get_auto_increment() was not expecting any errors from the storage engine.
That was wrong, errors could happen.
* ha_partition::get_auto_increment() was doing index lookups in partition under a mutex.
This was redundant (engine transaction isolation was covering that anyway)
and harmful (causing deadlocks).

MDEV-6483 - Deadlock around rw_lock_debug_mutex on PPC64
This problem affects only debug builds on PPC64.
There are at least two race conditions around
rw_lock_debug_mutex_enter and rw_lock_debug_mutex_exit:
- rw_lock_debug_waiters was loaded/stored without setting
appropriate locks/memory barriers.
- there is a gap between calls to os_event_reset() and
os_event_wait() and in such case we're supposed to pass
return value of the former to the latter.
Fixed by replacing self-cooked spinlocks with system mutexes.
These days system mutexes offer much better performance. OTOH
performance is not that critical for debug builds.
MDEV-6450 - MariaDB crash on Power8 when built with advance tool
chain
InnoDB mutex_exit() function calls __sync_test_and_set() to release
the lock. According to manual this function is supposed to create
"acquire" memory barrier whereas in fact we need "release" memory
barrier at mutex_exit().
The problem isn't repeatable with gcc because it creates
"acquire-release" memory barrier for __sync_test_and_set().
ATC creates just "acquire" barrier.
Fixed by creating proper barrier at mutex_exit() by using
__sync_lock_release() instead of __sync_test_and_set().

Problem:
We maintain two rb trees in each dict_table_t. The foreign_rbt must be in
sync with foreign_list. The referenced_rbt must be in sync with
referenced_list. There is one function which checks this consistency and it
failed, resulting in an assert failure.
The root cause of the problem was identified that the search order was
lost in the referenced_rbt. This is because while renaming the table,
we didn't not refresh this referenced_rbt.
Solution:
When a foreign key is renamed, we must delete and re-insert into both
foreign_rbt and referenced_rbt.

Part of this work is based on Stewart Smitch's memory barrier and lower priori
patches for power8.
- Added memory syncronization for innodb & xtradb for power8.
- Added HAVE_WINDOWS_MM_FENCE to CMakeList.txt
- Added os_isync to fix a syncronization problem on power
- Added log_get_lsn_nowait which is now used srv_error_monitor_thread to ensur
if log mutex is locked.
All changes done both for InnoDB and Xtradb
them sorted by file position. Firstly a new value is stored in indexes
to know if they are sorted, preventing to do the sorting when it is not
needed. Secondly, almost all in now done in connect instead of being
done by the different file access method classes. This pepares the future
use of temporary files for all table types and also fix the bug that was
occuring when partially using a multi-column index because of false MRR
like call of position followed by unsorted rnd_pos no more using indexing.

- Handle indexed UPDATE/DELETE. Previously this was just tested and
an error message send when it could not be done. Now CONNECT can
do it in all the cases. It is done by a MRR like tchnique by making
a list of all update or delete to do, sort them, then execute them.

This bug only happens in case of paritioned tables used in LOCK TABLES and implicit_commit() was called
(as part of trying to execute a CREATE TABLE withing lock tables)
The problem was that Aria could not move the tables from one transaction to the new one, as thd->open_tables contained
a partitioned tables and not an Aria table.
Fix:
- Store a list of all open tables that are part of a share in share->open_tables
- In maria::implict_commit() use transaction->used_tables & share->open_tables to find out which tables
was part of the current transaction instead of using thd->open_tables, which may contain partitioned tables.

This problem affects only debug builds on PPC64.
There are at least two race conditions around
rw_lock_debug_mutex_enter and rw_lock_debug_mutex_exit:
- rw_lock_debug_waiters was loaded/stored without setting
appropriate locks/memory barriers.
- there is a gap between calls to os_event_reset() and
os_event_wait() and in such case we're supposed to pass
return value of the former to the latter.
Fixed by replacing self-cooked spinlocks with system mutexes.
These days system mutexes offer much better performance. OTOH
performance is not that critical for debug builds.
This is to get same test results on Linux and Windows

This version adds the following to CONNECT:
- MRR support (similar to the MyISAM one)
- Block, Remote and dynamic indexing
- Partitioning support (using the PARTITION engine)

This commit of the main branch adds:
- A change needed to have the engine function check_if_supported_inplace_alter
called for partition tables (was done manually in the sub-branch) by adding
the preparser define: PARTITION_SUPPORTS_INPLACE_ALTER
modified:
sql/CMakeLists.txt
- A fix concerning the FileExists function. It was needed to force the function
table_flags to return the same flags for all partitions. This is tested by
the partition engine and raises an error if flags are not equal.
The way file name, table name and connection string are retrieved has been
modified to cope with it.

Reason for the problem was that the hash of changed files in the key cache was too small (was 128). Fixed by making the hash size larger and changeable.
- Introduced key-cache-file-hash-size (default 512) for MyISAM and aria_pagecache_file_hash_size (default 512) for Aria.
- Added new status variable "Feature_delay_key_write" which counts number of tables opened that are using delay_key_write

InnoDB mutex_exit() function calls __sync_test_and_set() to release
the lock. According to manual this function is supposed to create
"acquire" memory barrier whereas in fact we need "release" memory
barrier at mutex_exit().
The problem isn't repeatable with gcc because it creates
"acquire-release" memory barrier for __sync_test_and_set().
ATC creates just "acquire" barrier.
Fixed by creating proper barrier at mutex_exit() by using
__sync_lock_release() instead of __sync_test_and_set().

Merge the patches into MariaDB 10.0 main.
With this patch, parallel replication will now automatically retry a
transaction that fails due to deadlock or other temporary error, same as
single-threaded replication.
We catch deadlocks with InnoDB transactions due to enforced commit order. If
T1 must commit before T2 in parallel replication and T1 ends up waiting for T2
inside InnoDB, we kill T2 and retry it later to resolve the deadlock
automatically.
After-review changes.
For this patch in 10.0, we do not introduce a new public storage engine API,
we just fix the InnoDB/XtraDB issues. In 10.1, we will make a better public
API that can be used for all storage engines (MDEV-6429).
Eliminate the background thread that did deadlock kills asynchroneously.
Instead, we ensure that the InnoDB/XtraDB code can handle doing the kill from
inside the deadlock detection code (when thd_report_wait_for() needs to kill a
later thread to resolve a deadlock).
(We preserve the part of the original patch that introduces dedicated mutex
and condition for the slave init thread, to remove the abuse of
LOCK_thread_count for start/stop synchronisation of the slave init thread).
IN RECOVERY
During redo log processing, the data dictionary is not available. We should
check it in dict_find_table_by_space() to prevent SEGV error.

Problem:
When a unique secondary index is scanned for duplicate checking, gap locks
were not taken if the transaction had isolation level <= READ COMMITTED.
This change was done while fixing Bug #16133801 UNEXPLAINABLE INNODB UNIQUE
INDEX LOCKS ON DELETE + INSERT WITH SAME VALUES (rb#2035). Because of this
the duplicate check logic failed, and resulted in duplicate values in unique
secondary index.
Solution:
When a unique secondary index is scanned for duplicate checking, gap locks
must be taken irrespective of the transaction isolation level. This is
achieved by reverting rb#2035.

Analysis: For some reason table stats for a table pointed from a index
is not initialized. Added additional warning output on this situation
and table stats initialization. This is better than asserting.
