b22959903b MDEV-7943 - pthread_getspecific() takes 0.76% in OLTP RO
Added THD argument to select_result and all derivative classes.
This reduces number of pthread_getspecific calls from 796 to 776 per OLTP RO
transaction.

b83f692565 MDEV-6668: Server crashes in check_view_single_update on concurrent DDL/DML flow with views and triggers
Call mysql_derived_reinit() if we are reusing view.
This is needed as during a previous error condition the view may not have been reset

  Added prototype
sql/sql_insert.cc:

when restoring auto-inc value in INSERT ... ON DUPLICATE KEY UPDATE, take into account that
1. it may be changed in the UPDATE clause (old code did that)
2. it may be changed in the INSERT clause and then cause a dup key (old code missed that)

db21fddc37 MDEV-6676: Optimistic parallel replication
Implement a new mode for parallel replication. In this mode, all transactions
are optimistically attempted applied in parallel. In case of conflicts, the
offending transaction is rolled back and retried later non-parallel.

This is an early-release patch to facilitate testing, more changes to user
interface / options will be expected. The new mode is not enabled by default.

6a2c170141 MDEV-6849 ON UPDATE CURRENT_TIMESTAMP doesn't always work
reset default fields not for every modified row, but only once,
at the beginning, as the set of modified fields doesn't change.

exception: INSERT ... ON DUPLICATE KEY UPDATE - the set of fields
does change per row and in that case we reset default fields per row.

70823e1d91 MDEV-5120 Test suite test maria-no-logging fails
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.

df4dd593f2 MDEV-6247: Merge 10.0-galera to 10.1.
Merged lp:maria/maria-10.0-galera up to revision 3879.

Added a new functions to handler API to forcefully abort_transaction,
producing fake_trx_id, get_checkpoint and set_checkpoint for XA. These
were added for future possiblity to add more storage engines that
could use galera replication.

2870bd7423 Bug#17283409 4-WAY DEADLOCK: ZOMBIES, PURGING BINLOGS,
SHOW PROCESSLIST, SHOW BINLOGS

Problem:  A deadlock was occurring when 4 threads were
involved in acquiring locks in the following way
Thread 1: Dump thread ( Slave is reconnecting, so on
              Master, a new dump thread is trying kill
              zombie dump threads. It acquired thread's
              LOCK_thd_data and it is about to acquire
              mysys_var->current_mutex ( which LOCK_log)
Thread 2: Application thread is executing show binlogs and
               acquired LOCK_log and it is about to acquire
               LOCK_index.
Thread 3: Application thread is executing Purge binary logs
               and acquired LOCK_index and it is about to
               acquire LOCK_thread_count.
Thread 4: Application thread is executing show processlist
               and acquired LOCK_thread_count and it is
               about to acquire zombie dump thread's
               LOCK_thd_data.
Deadlock Cycle:
     Thread 1 -> Thread 2 -> Thread 3-> Thread 4 ->Thread 1

The same above deadlock was observed even when thread 4 is
executing 'SELECT * FROM information_schema.processlist' command and
acquired LOCK_thread_count and it is about to acquire zombie
dump thread's LOCK_thd_data.

Analysis:
There are four locks involved in the deadlock.  LOCK_log,
LOCK_thread_count, LOCK_index and LOCK_thd_data.
LOCK_log, LOCK_thread_count, LOCK_index are global mutexes
where as LOCK_thd_data is local to a thread.
We can divide these four locks in two groups.
Group 1 consists of LOCK_log and LOCK_index and the order
should be LOCK_log followed by LOCK_index.
Group 2 consists of other two mutexes
LOCK_thread_count, LOCK_thd_data and the order should
be LOCK_thread_count followed by LOCK_thd_data.
Unfortunately, there is no specific predefined lock order defined
to follow in the MySQL system when it comes to locks across these
two groups. In the above problematic example,
there is no problem in the way we are acquiring the locks
if you see each thread individually.
But If you combine all 4 threads, they end up in a deadlock.

Fix: 
Since everything seems to be fine in the way threads are taking locks,
In this patch We are changing the duration of the locks in Thread 4
to break the deadlock. i.e., before the patch, Thread 4
('show processlist' command) mysqld_list_processes()
function acquires LOCK_thread_count for the complete duration
of the function and it also acquires/releases
each thread's LOCK_thd_data.

LOCK_thread_count is used to protect addition and
deletion of threads in global threads list. While show
process list is looping through all the existing threads,
it will be a problem if a thread is exited but there is no problem
if a new thread is added to the system. Hence a new mutex is
introduced "LOCK_thd_remove" which will protect deletion
of a thread from global threads list. All threads which are
getting exited should acquire LOCK_thd_remove
followed by LOCK_thread_count. (It should take LOCK_thread_count
also because other places of the code still thinks that exit thread
is protected with LOCK_thread_count. In this fix, we are changing
only 'show process list' query logic )
(Eg: unlink_thd logic will be protected with
LOCK_thd_remove).

Logic of mysqld_list_processes(or file_schema_processlist)
will now be protected with 'LOCK_thd_remove' instead of
'LOCK_thread_count'.

Now the new locking order after this patch is:
LOCK_thd_remove -> LOCK_thd_data -> LOCK_log ->
LOCK_index -> LOCK_thread_count

10ae6e35d0 Fixed that the we don't change CREATE to CREATE OR REPLACE, except if the slave removed an existing table as part of CREATE.
This will help the following replicaition scenario:
MariaDB 10.0 master (statement replication) -> MariaDB 10.0 slave (row based replication) -> MySQL or MariaDB 5.x slave

c4bb7cd6dc Fix for MDEV-5589: "Discrepancy in binlog on half-failed CREATE OR REPLACE"
Now if CREATE OR REPLACE fails but we have deleted a table already, we will generate a DROP TABLE in the binary log.
This fixes this issue.

In addition, for a failing CREATE OR REPLACE TABLE ... SELECT we don't generate a log of all the inserted rows, only the DROP TABLE.

I added code for not logging DROP TEMPORARY TABLE for tables where the CREATE TABLE was not logged. This code will be activated in 10.1
by removing the code protected by DONT_LOG_DROP_OF_TEMPORARY_TABLES.

048e9c40a6 MDEV-5492 - Reduce usage of LOCK_open: TABLE::in_use
Move TABLE::in_use out of LOCK_open.

This is done with assumtion that foreign threads accessing TABLE::in_use
will only need consistent value _after_ marking table for flush and purging
unused table instances. In this case TABLE::in_use will always point to a
valid thread object.

Previously FLUSH TABLES thread may wait for tables flushed subsequently by
concurrent threads which breaks the above assumption, e.g.:
open tables: t1 (version= 1)
thr1 (FLUSH TABLES): refresh_version++
thr1 (FLUSH TABLES): purge table cache
open tables: none
thr2 (SELECT * FROM t1): open tables: t1
open tables: t1 (version= 2)
thr2 (FLUSH TABLES): refresh_version++
thr2 (FLUSH TABLES): purge table cache
thr1 (FLUSH TABLES): wait for old tables (including t1 with version 2)

It is fixed so that FLUSH TABLES waits only for tables that were open
heretofore.

5426facdcb Replication changes for CREATE OR REPLACE TABLE
- CREATE TABLE is by default executed on the slave as CREATE OR REPLACE
- DROP TABLE is by default executed on the slave as DROP TABLE IF NOT EXISTS

This means that a slave will by default continue even if we try to create
a table that existed on the slave (the table will be deleted and re-created) or
if we try to drop a table that didn't exist on the slave.
This should be safe as instead of having the slave stop because of an inconsistency between
master and slave, it will fix the inconsistency.
Those that would prefer to get a stopped slave instead for the above cases can set slave_ddl_exec_mode to STRICT. 

- Ensure that a CREATE OR REPLACE TABLE which dropped a table is replicated
- DROP TABLE that generated an error on master is handled as an identical DROP TABLE on the slave (IF NOT EXISTS is not added in this case)
- Added slave_ddl_exec_mode variable to decide how DDL's are replicated

New logic for handling BEGIN GTID ... COMMIT from the binary log:

- When we find a BEGIN GTID, we start a transaction and set OPTION_GTID_BEGIN
- When we find COMMIT, we reset OPTION_GTID_BEGIN and execute the normal COMMIT code.
- While OPTION_GTID_BEGIN is set:
  - We don't generate implict commits before or after statements
  - All tables are regarded as transactional tables in the binary log (to ensure things are executed exactly as on the master)
- We reset OPTION_GTID_BEGIN also on rollback

This will help ensuring that we don't get any sporadic commits (and thus new GTID's) on the slave and will help keep the GTID's between master and slave in sync.

7ffc9da093 Implementation of MDEV-5491: CREATE OR REPLACE TABLE
Using CREATE OR REPLACE TABLE is be identical to

DROP TABLE IF EXISTS table_name;
CREATE TABLE ...;

Except that:

* CREATE OR REPLACE is be atomic (now one can create the same table between drop and create).
* Temporary tables will not shadow the table name for the DROP as the CREATE TABLE tells us already if we are using a temporary table or not.
* If the table was locked with LOCK TABLES, the new table will be locked with the same lock after it's created.

Implementation details:
- We don't anymore open the to-be-created table during CREATE TABLE, which the original code did.
  - There is no need to open a table we are planning to create. It's enough to check if the table exists or not.
- Removed some of duplicated code for CREATE IF NOT EXISTS.
- Give an error when using CREATE OR REPLACE with IF NOT EXISTS (conflicting options).
- As a side effect of the code changes, we don't anymore have to internally re-prepare prepared statements with CREATE TABLE if the table exists.
- Made one code path for all testing if log table are in use.
- Better error message if one tries to create/drop/alter a log table in use
- Added back disabled rpl_row_create_table test as it now seams to work and includes a lot of interesting tests.
- Added HA_LEX_CREATE_REPLACE to mark if we are using CREATE OR REPLACE
- Aligned CREATE OR REPLACE parsing code in sql_yacc.yy for TABLE and VIEW
- Changed interface for drop_temporary_table() to make it more reusable
- Changed Locked_tables_list::init_locked_tables() to work on the table object instead of the table list object. Before this it used a mix of both, which was not good.
- Locked_tables_list::unlock_locked_tables(THD *thd) now requires a valid thd argument. Old usage of calling this with 0 i changed to instead call Locked_tables_list::reset()
- Added functions Locked_tables_list:restore_lock() and Locked_tables_list::add_back_last_deleted_lock() to be able to easily add back a locked table to the lock list.
- Added restart_trans_for_tables() to be able to restart a transaction.
- DROP_ACL is required if one uses CREATE TABLE OR REPLACE.
- Added drop of normal and temporary tables in create_table_imp() if CREATE OR REPLACE was used.
- Added reacquiring of table locks in mysql_create_table() and mysql_create_like_table()

d15b3386db Fix for MDEV-5531: double call procedure in one session - hard shutdown the server
Main fix was to not cache derivied tables as they may be temporary tables that are deleted before the next query.

sql/records.cc:
  Also accept INTERNAL_TMP_TABLE for memmap
sql/sql_base.cc:
  More DBUG_PRINT
  Fixed that setup_natural_join_row_types() is not run twice.
  Original code modified context->first_name_resolution_table also for second executions.
  This was wrong as this could give wrong results if some joins had been optimized away between calls.
sql/sql_derived.cc:
  Mark derived tables as internal temporary tables (INTERNAL_TMP_TABLE), not as NON_TRANSACTIONAL_TMP_TABLE.
  This is more correct as the tables are not visible by the end user.
sql/sql_insert.cc:
  Reset pos_in_table_list before calling fix_fields.
  One of the consequences of the change of not caching all generated tables in Item_ident is that
  pos_in_table_list needs to be correct in calls to fix_fields.
sql/sql_lex.cc:
  More DBUG_PRINT
sql/sql_parse.cc:
  Don't cache derivied tables as they may be temporary tables that are deleted before the next query

  the code would call select_insert::prepare2(), which would call 
  handler->ha_start_bulk_insert().  The corresponding handler->end_bulk_insert() 
  call is made from select_insert::send_eof or select_insert::abort_result_set 
  which are never called for EXPLAIN INSERT SELECT.
- Fixed by re-using approach of mysql-5.6: don't call ha_start_bulk_insert() if 
  we are in EXPLAIN.

57a267a8c0 Merge from 10.0-base to 10.0 the feature MDEV-4506: Parallel replication.
The merge is still missing a few hunks related to temporary tables and
InnoDB log file size. The associated code did not seem to exist in
10.0, so the merge of that needs more work. Until this is fixed, there
are a number of test failures as a result.

4bed7aa858 MDEV-3798: [SHOW] EXPLAIN UPDATE/DELETE, Memory leak in binlog.binlog_base64_flag:
- It turns out, there are statements that will call lex_start(thd->lex) 
  after parsing has been finished. lex_start() will set lex->explain=NULL,
  which will lose the pointer to already allocated Explain_plan object.
- To get rid of this, switch to lazy creation of lex->explain.  Now, it is 
  created only when we get a part ot query plan.

105e3ae6c9 MDEV-3798: EXPLAIN UPDATE/DELETE
Update the SHOW EXPLAIN code to work with the 
new architecture (part#1):
Before, SHOW EXPLAIN operated on real query plan structures, 
which meant it had to check when SELECTs are created/deleted.
SELECTs would call apc_target->enable() when they got a query 
plan and disable() when their query plan was deleted.

Now, Explain data structure becomes available at once (and we
call apc_target->enable()) and then it stays until it is deleted
(when that happens, we call apc_target->disable()).
