e0887df8e1 Bug#11766249 bug#59316: PARTITIONING AND INDEX_MERGE MEMORY LEAK
When executing row-ordered-retrieval index merge,
the handler was cloned, but it used the wrong
memory root, so instead of allocating memory
on the thread/query's mem_root, it used the table's
mem_root, resulting in non released memory in the
table object, and was not freed until the table was
closed.

Solution was to ensure that memory used during cloning
of a handler was allocated from the correct memory root.

This was implemented by fixing handler::clone() to also
take a name argument, so it can be used with partitioning.
And in ha_partition only allocate the ha_partition's ref, and
call the original ha_partition partitions clone() and set at cloned
partitions.

20acfbf30d Fix for: LP #634955: Assert in _ma_update_at_original_place()
Added locking of lock mutex when updating status in external_unlock() for Aria and MyISAM tables.
Fixed that 'source' command doesn't cause mysql command line tool to exit on error.
DEBUG_EXECUTE() and DEBUG_EVALUATE_IF() should not execute things based on wildcards. (Allows one to run --debug with mysql-test-run scripts that uses @debug)
Fixed several core dump, deadlock and crashed table bugs in handling of LOCK TABLE with MERGE tables:
- Added priority of locks to avoid crashes with MERGE tables.
- Added thr_lock_merge() to allow one to merge two results of thr_lock().
Fixed 'not found row' bug in REPLACE with Aria tables.
Mark MyISAM tables that are part of MERGE with HA_OPEN_MERGE_TABLE and set the locks to have priority THR_LOCK_MERGE_PRIV.
- By sorting MERGE tables last in thr_multi_unlock() it's safer to release and relock them many times (can happen when TRIGGERS are created)
Avoid printing (null) in debug file (to easier find out wrong NULL pointer usage with %s).



client/mysql.cc:
  Fixed that 'source' command doesn't cause mysql command line tool to exit on error.
client/mysqltest.cc:
  Don't send NULL to fn_format(). (Can cause crash on Solaris when using --debug)
dbug/dbug.c:
  DEBUG_EXECUTE() and DEBUG_EVALUATE_IF() should not execute things based on wildcards.
include/my_base.h:
  Added flag to signal if one opens a MERGE table.
  Added extra() command to signal that one is not part of a MERGE table anymore.
include/thr_lock.h:
  Added priority for locks (needed to fix bug in thr_lock when using MERGE tables)
  Added option to thr_unlock() if get_status() should be called.
  Added prototype for thr_merge_locks().
mysql-test/mysql-test-run.pl:
  Ignore crashed table warnings for tables named 'crashed'.
mysql-test/r/merge.result:
  Renamed triggers to make debugging easier.
  Added some CHECK TABLES to catch errors earlier.
  Additional tests.
mysql-test/r/merge_debug.result:
  Test of error handling when reopening MERGE tables.
mysql-test/r/udf_query_cache.result:
  Added missing flush status
mysql-test/suite/parts/r/partition_repair_myisam.result:
  Update results
mysql-test/t/merge.test:
  Renamed triggers to make debugging easier.
  Added some CHECK TABLES to catch errors earlier.
  Additional tests.
mysql-test/t/merge_debug.test:
  Test of error handling when reopening MERGE tables.
mysql-test/t/udf_query_cache.test:
  Added missing flush status
mysys/my_getopt.c:
  Removed not used variable
mysys/my_symlink2.c:
  Changed (null) to (NULL) to make it easier to find NULL arguments to DBUG_PRINT() functions.
  (On linux, NULL to sprintf is printed 'null')
mysys/thr_lock.c:
  Added priority of locks to avoid crashes with MERGE tables.
  Added thr_lock_merge() to allow one to merge two results of thr_lock().
  - This is needed for MyISAM as all locked table must share the same status. If not, you will not see newly inserted rows in other instances of the table.
  If calling thr_unlock() with THR_UNLOCK_UPDATE_STATUS, call update_status() and restore_status() for the locks. This is needed in some rare cases where we call thr_unlock() followed by thr_lock() without calling external_unlock/external_lock in between.
  Simplify loop in thr_multi_lock().
  Added 'start_trans', which is called at end of thr_multi_lock() when all locks are taken.
  - This was needed by Aria to ensure that transaction is started when we got all locks, not at get_status(). Without this, some rows could not be visible when we lock two tables at the same time, causing REPLACE using two tables to fail unexpectedly.
sql/handler.cc:
  Add an assert() in handler::print_error() for "impossible errors" (like table is crashed) when --debug-assert-if-crashed-table is used.
sql/lock.cc:
  Simplify mysql_lock_tables() code if get_lock_data() returns 0 locks.
  Added new parameter to thr_multi_unlock()
  In mysql_unlock_read_tables(), call first externa_unlock(), then thr_multi_unlock();  This is same order as we do in mysql_unlock_tables().
  Don't abort locks in mysql_lock_abort() for merged tables when a MERGE table is deleted; Would cause a spin lock.
  Added call to thr_merge_locks() in mysql_lock_merge() to ensure consistency in thr_locks().
  - New locks of same type and table is stored after the old lock to ensure that we get the status from the original lock.
sql/mysql_priv.h:
  Added debug_assert_if_crashed_table
sql/mysqld.cc:
  Added --debug-assert-if-crashed-table
sql/parse_file.cc:
  Don't print '(null)' in DBUG_PRINT of no dir given
sql/set_var.cc:
  Increase default size of buffer for @debug variable.
sql/sql_base.cc:
  In case of error from reopen_table() in reopen_tables(), call unlock_open_table() and restart loop.
  - This fixed bug when we twice deleted same table from open_cache.
  Don't take name lock for already name locked table in open_unireg_entry().
  - Fixed bug when doing repair in reopen_table().
  - In detach_merge_children(), always detach if 'clear_refs' is given. We can't trust parent->children_attached as this function can be called twice, first time with clear_refs set to 0.
sql/sql_class.cc:
  Changed printing of (null) to "" in set_thd_proc_info()
sql/sql_parse.cc:
  Added DBUG
sql/sql_trigger.cc:
  Don't call unlink_open_table() if reopen_table() fails as the table may already be freed.
storage/maria/ma_bitmap.c:
  Fixed DBUG_ASSERT() in allocate_tail()
storage/maria/ma_blockrec.c:
  Fixed wrong calculation of row length for very small rows in undo_row_update().
  - Fixes ASSERT() when doing undo.
storage/maria/ma_blockrec.h:
  Added _ma_block_start_trans() and _ma_block_start_trans_no_versioning()
storage/maria/ma_locking.c:
  Call _ma_update_status_with_lock() when releasing write locks.
  - Fixes potential problem with updating status without the proper lock.
storage/maria/ma_open.c:
  Changed to use start_trans() instead of get_status() to ensure that we see all rows in all locked tables when we got the locks.
  - Fixed 'not found row' bug in REPLACE with Aria tables.
storage/maria/ma_state.c:
  Added _ma_update_status_with_lock() and _ma_block_start_trans().
  This is to ensure that we see all rows in all locked tables when we got the locks.
storage/maria/ma_state.h:
  Added _ma_update_status_with_lock()
storage/maria/ma_write.c:
  More DBUG_PRINT
storage/myisam/mi_check.c:
  Fixed error message
storage/myisam/mi_extra.c:
  Added HA_EXTRA_DETACH_CHILD:
  - Detach MyISAM table to not be part of MERGE table (remove flag & lock priority).
storage/myisam/mi_locking.c:
  Call mi_update_status_with_lock() when releasing write locks.
  - Fixes potential problem with updating status without the proper lock.
  Change to use new HA_OPEN_MERGE_TABLE flag to test if MERGE table.
  Added mi_fix_status(), called by thr_merge().
storage/myisam/mi_open.c:
  Added marker if part of MERGE table.
  Call mi_fix_status() in thr_lock() for transactional tables.
storage/myisam/myisamdef.h:
  Change my_once_flag to uint, as it stored different values than just 0/1
  Added 'open_flag' to store state given to mi_open()
storage/myisammrg/ha_myisammrg.cc:
  Add THR_LOCK_MERGE_PRIV to THR_LOCK_DATA to get MERGE locks sorted after other types of locks.
storage/myisammrg/myrg_locking.c:
  Remove windows specific code.
storage/myisammrg/myrg_open.c:
  Use HA_OPEN_MERGE_TABLE to mi_open().
  Set HA_OPEN_MERGE_TABLE for linked MyISAM tables.
storage/xtradb/buf/buf0buf.c:

storage/xtradb/buf/buf0lru.c:
  Initialize variable that could be used not initialized.

3e9c52250a Bug#45288: pb2 returns a lot of compilation warnings
Fix assorted warnings that are generated in optimized builds.
Most of it is silencing variables that are set but unused.

This patch also introduces the MY_ASSERT_UNREACHABLE macro
which helps the compiler to deduce that a certain piece of
code is unreachable.

include/my_compiler.h:
  Use GCC's __builtin_unreachable if available. It allows
  GCC to deduce the unreachability of certain code paths,
  thus avoiding warnings that, for example, accused that a
  variable could be used without being initialized (due to
  unreachable code paths).

0eb26fdfa8 Bug#53445: Build with -Wall and fix warnings that it generates
Apart strict-aliasing warnings, fix the remaining warnings
generated by GCC 4.4.4 -Wall and -Wextra flags.

One major source of warnings was the in-house function my_bcmp
which (unconventionally) took pointers to unsigned characters
as the byte sequences to be compared. Since my_bcmp and bcmp
are deprecated functions whose only difference with memcmp is
the return value, every use of the function is replaced with
memcmp as the special return value wasn't actually being used
by any caller.

There were also various other warnings, mostly due to type
mismatches, missing return values, missing prototypes, dead
code (unreachable) and ignored return values.

BUILD/SETUP.sh:
  Remove flags that are implied by -Wall and -Wextra.
  Do not warn about unused parameters in C++.
BUILD/check-cpu:
  Print only the compiler version instead of verbose banner.
  Although the option is gcc specific, the check was only
  being used for GCC specific checks anyway.

  position if fgets succeed -- if it fails, the function will
  bail out and return a error.
extra/yassl/taocrypt/include/blowfish.hpp:
  Use a single array instead of accessing positions of the sbox_

0f9ddfa9d8 Bug#42733: Type-punning warnings when compiling MySQL --
strict aliasing violations.

One somewhat major source of strict-aliasing violations and
related warnings is the SQL_LIST structure. For example,
consider its member function `link_in_list` which takes
a pointer to pointer of type T (any type) as a pointer to
pointer to unsigned char. Dereferencing this pointer, which
is done to reset the next field, violates strict-aliasing
rules and might cause problems for surrounding code that
uses the next field of the object being added to the list.

The solution is to use templates to parametrize the SQL_LIST
structure in order to deference the pointers with compatible
types. As a side bonus, it becomes possible to remove quite
a few casts related to acessing data members of SQL_LIST.

sql/handler.h:
  Use the appropriate template type argument.
sql/item.cc:
  Remove now-unnecessary cast.
sql/item_subselect.cc:
  Remove now-unnecessary casts.
sql/item_sum.cc:
  Use the appropriate template type argument.
  Remove now-unnecessary cast.
sql/mysql_priv.h:
  Move SQL_LIST structure to sql_list.h
  Use the appropriate template type argument.
sql/sp.cc:
  Remove now-unnecessary casts.
sql/sql_delete.cc:
  Use the appropriate template type argument.
  Remove now-unnecessary casts.
sql/sql_derived.cc:
  Remove now-unnecessary casts.
sql/sql_lex.cc:
  Remove now-unnecessary casts.
sql/sql_lex.h:
  SQL_LIST now takes a template type argument which must
  match the type of the elements of the list. Use forward
  declaration when the type is not available, it is used
  in pointers anyway.
sql/sql_list.h:
  Rename SQL_LIST to SQL_I_List. The template parameter is
  the type of object that is stored in the list.
sql/sql_olap.cc:
  Remove now-unnecessary casts.
sql/sql_parse.cc:
  Remove now-unnecessary casts.
sql/sql_prepare.cc:
  Remove now-unnecessary casts.

  Remove now-unnecessary casts.

1d2aeb3da2 BUG#48265 - MRG_MYISAM problem (works in 5.0.85, does't
work in 5.1.40)

MERGE engine fails to open child table from a different
database if child table/database name contains characters
that are subject for table name to filename encoding
(WL1324).

Another problem is that MERGE engine didn't properly open
child table from the same database if child table name
contains characters like '/', '#'.

The problem was that table name to file name encoding was
applied inconsistently:
* On CREATE: encode table name + database name if child
  table is in different database; do not encode table
  name if child table is in the same database;
* No decoding on open.

With this fix child table/database names are always
encoded on CREATE and decoded on open. Compatibility
with older tables preserved.

Along with this patch comes fix for SHOW CREATE TABLE,
which used to show child table/database path instead
of child table/database names.

  A test case for BUG#48265.

storage/myisammrg/ha_myisammrg.cc:
  On CREATE always write child table/database name encoded
  by table name to filename encoding to dot-MRG file.
  
  On open decode child table/database name.
  Compatibilty with previous versions preserved.
  
  Fixed ::append_create_info() to return child
  table/database name instead of path.
storage/myisammrg/myrg_open.c:
  Move if (has_path) branch from myrg_parent_open() to
  myisammrg_parent_open_callback. The callback function
  needs to know if child table was written along with
  database name to dot-MRG file. Needed for compatibility
  reasons.

0d61bd9dce Bug#45800 crash when replacing into a merge table and there is a duplicate
A REPLACE in the MERGE engine is actually a REPLACE
into one (FIRST or LAST) of the underlying MyISAM
tables. So in effect the server works on the meta
data of the MERGE table, while the real insert happens
in the MyISAM table.

The MERGE table has no index, while MyISAM has a
unique index. When a REPLACE into a MERGE table (
and the REPLACE conflicts with a duplicate in a
child table) is done, we try to access the duplicate
key information for the MERGE table. This information
actually does not exist, hence this results in a crash.

The problem can be resolved by modifying the MERGE
engine to provide us the duplicate key information
directly, instead of just returning the MyISAM index
number as the error key. Then the SQL layer (or "the
server") does not try to access the key_info of the
MERGE table, which does not exist.

The current patch modifies the MERGE engine to provide
the position for a record where a unique key violation
occurs.

include/myisammrg.h:
  Bug#45800 crash when replacing into a merge table and there is a duplicate
  
  Add a member to the st_mymerge_info structure that will
  store the duplicate key offset in the MERGE table. This
  offset will be the sum of the record offset of the MyISAM
  table within the MERGE table and the offset of the record
  within the MyISAM table.

  We modify the myrg_status function to return the position of the

  of the start position of the records.

2b26729ece Bug #45796: invalid memory reads and writes when altering merge
and base tables 

myrg_attach_children() could reuse a buffer that was allocated 
previously based on a definition of a child table. The problem 
was that the child's definition might have been changed, so 
reusing the buffer could lead to crashes or valgrind errors 
under some circumstances. 
 
Fixed by changing myrg_attach_children() so that the 
rec_per_key_part buffer is reused only when the child table
have not changed, and reallocated otherwise (the old buffer is 
deallocated if necessary).


include/myisammrg.h:
  Added a pointer to need_compat_check as an argument to
  myrg_attach_children().
mysql-test/r/merge.result:
  Added a test case for bug #45796.

b125770aaa We are now using Valgrind rather than purify, and have for quite some time.
Consequently, rename HAVE_purify to HAVE_valgrind, and related changes.
Leave some comments about purify when not clear that they apply also to Valgrind.
Fix redundant IF_VALGRIND declaration.

Misc. small fixes:
 - Fixes for pool-of-threads patch.
 - Fixes for push of PBXT storage engine.
 - mysql-test-run.pl fix.
 - Fix build problem in compile-pentium64-max.


BUILD/SETUP.sh:
  Rename purify -> valgrind.
BUILD/build_mccge.sh:
  Rename purify -> valgrind.
BUILD/compile-dist:
  Fix that PBXT was missing in source tarball after `BUILD/compile-dist && make dist`
BUILD/compile-pentium64-max:
  Fix a build problem with BUILD/compile-pentium64-max on CentOS/Fedora Core 10 amd64.
        
  On these systems, there is libz.so but no libz.a. Finding libz.so, ./configure decides
  to use system zlib. But since BUILD/compile-pentium64-max builds a fully static binary
  with -all-static, the link of mysqld fails due to missing libz.a.
        
  Fix by using bundled zlib in the build script.
BUILD/compile-solaris-sparc-purify:
  Rename purify -> valgrind.
include/m_string.h:
  Rename purify -> valgrind.
include/my_global.h:
  Rename purify -> valgrind.
mysql-test/Makefile.am:
  Fix that PBXT test suite was missing from `make dist` source tarball.
mysql-test/lib/mtr_unique.pm:
  Better fix to avoid races when chmod'ing the semaphore file.
  (Though using chmod 666 shared files in /tmp/ is still not a very good solution).
mysql-test/t/pool_of_threads.cnf:
  Fix that test case pool_of_threads fails if run on mysqld with no --with-libevent support.

92aee5a6c6 Bug#37631 Incorrect key file for table after upgrading from 5.0 to 5.1
The conformance checker was not taking into
account, and, making concessions for acceptable

The current patch relaxes the conformance
checker to ignore differences in key_alg

earlier than 4.1.

aa13f72b90 Bug#41305 server crashes when inserting duplicate row into a merge table
This problem comes while inserting a duplicate row in merge table 
without key but the child table has a primary key. 
While forming the error message handler tries to locate the key field
which is creating this problem but as there is no key on the merge
table there is a segmentation fault.

mysql-test/r/merge.result:
  Updated results with new test for this bug.
mysql-test/t/merge.test:
  Added new test to test error generated from a key on child table 
  where merge table doesn't have any key.
storage/myisammrg/ha_myisammrg.cc:
  Added a new check to see if the value of error key is higher than 
  the number of key in merge table and if it is the error key set 
  to MAX_KEY. The error message generation routine treats MAX_KEY as 
  unknown key and doesn't tries to access this in key_info.

e80537b791 Bug#40675 MySQL 5.1 crash with index merge algorithm and Merge tables
A Query in the MyISAM merge table was crashing 
if the index merge algorithm was being used

Index Merge optimization requires the reading of 
multiple indexes at the same time. Reading multiple 
indexes at once with current SE API means that we 
need to have handler instance for each to-be-read 
index. This is done by creating clones of the handlers 
instances. The clone internally does a open of the handler.

The open for a MERGE engine is handled in the following 
phases

1) open parent table
2) generate list of underlying
   table
3) attach underlying tables

But the current implementation does only the first 
phase (i.e.) open parent table.

The current patch fixes this at the MERGE engine level, 
by handling the clone operation within the MERGE engine 
rather than in the storage engine API. It opens and 
attaches the MyISAM tables on the MyISAM storage engine 
interface directly within the MERGE engine. The new MyISAM 
table instances, as well as the MERGE clone itself, are not 
visible in the table cache. This is not a problem because
all locking is handled by the original MERGE table from which
this is cloned of.

mysql-test/r/merge.result:
  updated the result file to reflect the new tests
  added to test the fix
mysql-test/t/merge.test:
  Added new tests to verify that the index merge
  algorithm does not crash in the merge engine.
storage/myisammrg/ha_myisammrg.cc:
  Implement the clone method, that handles
  
  1) Cloning the handler
  2) Opening underlying MYISAM child tables
  3) Copies the state of the original handler and the children
     into the cloned instances
  4) Sets the appropriate flags
storage/myisammrg/ha_myisammrg.h:
  Added a flag that is set to indicate that the current 
  instance is cloned. Also added the prototype or the clone 
  method.
storage/myisammrg/myrg_open.c:
  Since we do now again use myrg_open() in the server
  removed the comments marking this as deadcode.

for ENGINE=MRG_MYISAM (should be optimized out).

Before WL#3281 MERGE engine had the HA_NOT_EXACT_COUNT flag
unset, and it worked with COUNT optimization as desired.
After the removal of the HA_NOT_EXACT_COUNT flag neither
HA_STATS_RECORDS_IS_EXACT (opposite to former HA_NOT_EXACT_COUNT
flag) nor modern HA_HAS_RECORDS flag were not added to MERGE
table flag mask.

1. The HA_HAS_RECORDS table flag has been set.
2. The ha_myisammrg::records method has been overridden to
   calculate total number of records in underlying tables.

e223c32077 Bug#30273 - merge tables: Can't lock file (errno: 155)
The patch for Bug 26379 (Combination of FLUSH TABLE and
REPAIR TABLE corrupts a MERGE table) fixed this bug too.
However it revealed a new bug that crashed the server.

Flushing a merge table at the moment when it is between open
and attach of children crashed the server.

The flushing thread wants to abort locks on the flushed table.
It calls ha_myisammrg::lock_count() and ha_myisammrg::store_lock()
on the TABLE object of the other thread.

Changed ha_myisammrg::lock_count() and ha_myisammrg::store_lock()
to accept non-attached children. ha_myisammrg::lock_count() returns
the number of MyISAM tables in the MERGE table so that the memory
allocation done by get_lock_data() is done correctly, even if the
children become attached before ha_myisammrg::store_lock() is
called. ha_myisammrg::store_lock() will not return any lock if the
children are not attached.

This is however a change in the handler interface. lock_count()
can now return a higher number than store_lock() stores locks.
This is more safe than the reverse implementation would be.
get_lock_data() in the SQL layer is adjusted accordingly. It sets
MYSQL_LOCK::lock_count based on the number of locks returned by
the handler::store_lock() calls, not based on the numbers returned
by the handler::lock_count() calls. The latter are only used for
allocation of memory now.

No test case. The test suite cannot reliably run FLUSH between
lock_count() and store_lock() of another thread. The bug report
contains a program that can repeat the problem with some
probability.


include/myisammrg.h:
  Bug#30273 - merge tables: Can't lock file (errno: 155)
  Added mutex to struct st_myrg_info (MYRG_INFO).
sql/handler.h:
  Bug#30273 - merge tables: Can't lock file (errno: 155)
  Extended comments for handler::lock_count() and
  handler::store_lock().
sql/lock.cc:
  Bug#30273 - merge tables: Can't lock file (errno: 155)
  Changed get_lock_data() so that the final lock_count is taken
  from the number of locks returned from handler::store_lock()
  instead of from handler::lock_count().

  Fixed a purecov comment. (unrelated to the rest of the changeset)

Bug 19627 - temporary merge table locking
Bug 27660 - Falcon: merge table possible
Bug 30273 - merge tables: Can't lock file (errno: 155)

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.
