8664de2230 WL#5665: Removal of the autotools-based build system
The autotools-based build system has been superseded and
is being removed in order to ease the maintenance burden on
developers tweaking and maintaining the build system.

In order to support tools that need to extract the server
version, a new file that (only) contains the server version,
called VERSION, is introduced. The file contents are human
and machine-readable. The format is:

MYSQL_VERSION_MAJOR=5
MYSQL_VERSION_MINOR=5
MYSQL_VERSION_PATCH=8
MYSQL_VERSION_EXTRA=-rc

The CMake based version extraction in cmake/mysql_version.cmake
is changed to extract the version from this file. The configure
to CMake wrapper is retained for backwards compatibility and to
support the BUILD/ scripts. Also, a new a makefile target
show-dist-name that prints the server version is introduced.

VERSION:
  Add top-level version file.
cmake/mysql_version.cmake:
  Get version information from the top-level VERSION file.
  Do not cache the version components (MAJOR_VERSION, etc).
  Add MYSQL_RPM_VERSION as a replacement for MYSQL_U_SCORE_VERSION.

0de9a4abab MWL#74: Shared libmysqld.so library.
Switch makefiles to use libtool to build libmysqld.so, as well as all its
dependencies.

The previous MYSQL_PLUGIN_DEPENDS_ON_MYSQL_INTERNALS() declaration is removed,
as it does not work well with a libtool build. Instead, plugins that need it
can specify an alternate object in MYSQL_PLUGIN_STATIC() that will be used for
embedded library. The plugin must then take care itself of compiling the
special object for embedded, rebuilding the source files previously listed in
MYSQL_PLUGIN_DEPENDS_ON_MYSQL_INTERNALS() with @plugin_embedded_defs@ in
CFLAGS/CXXFLAGS. The extra target @XXX_embedded_static_target@ is available
for the special object, this will be empty when --without-embedded-server.

All in-tree plugins are changed to build their static targets with libtool.
Additional plugins that want to work with libmysqld.so will need to be
similarly modified to build with libtool (or otherwise provide an -fPIC
object). Dynamically loaded plugins are not affected.

The old libraries like libmysys.a, libmyisam.a and similar libraries, which
were installed by `make install` though this is of little use, are still built
and installed to not break package scripts etc. that expect them. These
libraries are kept static to avoid introducing new .so dependencies.

The patch also fixes a handfull of duplicate symbol linker errors, where we
included some object twice during linking; these for one reason or another did
not produce errors before but caused problems on some platforms with this
patch (eg. Mac OS X linker is more strict for shared objects).

This patch only does what is necessary to build libmysqld.so. There are some
more cleanups that are possible now that we are using libtool more fully,
which could done in subsequent patches (though we may not bother as we are
switching from autotools to CMake anyway):

 - In libmysql_r/, we should be able to just link libmysys.la etc, instead of
   symlinking and re-compiling sources into the directory.

 - In libmysql/, we can similarly avoid symlinking and recompiling sources if
   we instead build a libmysys_nothread.la library with appropriate CFLAGS and
   link that.

 - In sql/, we can build a separate target libmysql_int.la with appropriate
   CFLAGS for embedded and use that in libmysqld/ instead of symlinking
   sources.

 - libmysys.a, libmyisam.a and similar libraries could be installed as .so
   also to save on code size; or alternatively could be not installed at all.

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:
  Fixed compiler warning
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).

a5efb91dea Bug#49938: Failing assertion: inode or deadlock in fsp/fsp0fsp.c
Bug#54678: InnoDB, TRUNCATE, ALTER, I_S SELECT, crash or deadlock

- Incompatible change: truncate no longer resorts to a row by
row delete if the storage engine does not support the truncate
method. Consequently, the count of affected rows does not, in
any case, reflect the actual number of rows.

- Incompatible change: it is no longer possible to truncate a
table that participates as a parent in a foreign key constraint,
unless it is a self-referencing constraint (both parent and child
are in the same table). To work around this incompatible change
and still be able to truncate such tables, disable foreign checks
with SET foreign_key_checks=0 before truncate. Alternatively, if
foreign key checks are necessary, please use a DELETE statement
without a WHERE condition.

Problem description:

The problem was that for storage engines that do not support
truncate table via a external drop and recreate, such as InnoDB
which implements truncate via a internal drop and recreate, the
delete_all_rows method could be invoked with a shared metadata
lock, causing problems if the engine needed exclusive access
to some internal metadata. This problem originated with the
fact that there is no truncate specific handler method, which
ended up leading to a abuse of the delete_all_rows method that
is primarily used for delete operations without a condition.

Solution:

The solution is to introduce a truncate handler method that is
invoked when the engine does not support truncation via a table
drop and recreate. This method is invoked under a exclusive
metadata lock, so that there is only a single instance of the
table when the method is invoked.

Also, the method is not invoked and a error is thrown if
the table is a parent in a non-self-referencing foreign key
relationship. This was necessary to avoid inconsistency as
some integrity checks are bypassed. This is inline with the
fact that truncate is primarily a DDL operation that was
designed to quickly remove all data from a table.

mysql-test/suite/innodb/t/innodb-truncate.test:
  Add test cases for truncate and foreign key checks.
  Also test that InnoDB resets auto-increment on truncate.
mysql-test/suite/innodb/t/innodb.test:
  FK is not necessary, test is related to auto-increment.
  
  Update error number, truncate is no longer invoked if
  table is parent in a FK relationship.
mysql-test/suite/innodb/t/innodb_mysql.test:
  Update error number, truncate is no longer invoked if
  table is parent in a FK relationship.
  
  Use delete instead of truncate, test is used to check
  the interaction of FKs, triggers and delete.
mysql-test/suite/parts/inc/partition_check.inc:
  Fix typo.
mysql-test/suite/sys_vars/t/foreign_key_checks_func.test:
  Update error number, truncate is no longer invoked if
  table is parent in a FK relationship.
mysql-test/t/mdl_sync.test:
  Modify test case to reflect and ensure that truncate takes
  a exclusive metadata lock.
mysql-test/t/trigger-trans.test:
  Update error number, truncate is no longer invoked if
  table is parent in a FK relationship.
sql/ha_partition.cc:
  Reorganize the various truncate methods. delete_all_rows is now
  passed directly to the underlying engines, so as truncate. The
  code responsible for truncating individual partitions is moved
  to ha_partition::truncate_partition, which is invoked when a
  ALTER TABLE t1 TRUNCATE PARTITION p statement is executed.
  
  Since the partition truncate no longer can be invoked via
  delete, the bitmap operations are not necessary anymore. The
  explicit reset of the auto-increment value is also removed
  as the underlying engines are now responsible for reseting
  the value.
sql/handler.cc:
  Wire up the handler truncate method.
sql/handler.h:
  Introduce and document the truncate handler method. It assumes
  certain use cases of delete_all_rows.
  
  Add method to retrieve the list of foreign keys referencing a
  table. Method is used to avoid truncating tables that are
  parent in a foreign key relationship.
sql/share/errmsg-utf8.txt:
  Add error message for truncate and FK.
sql/sql_lex.h:
  Introduce a flag so that the partition engine can detect when
  a partition is being truncated. Used to give a special error.
sql/sql_parse.cc:
  Function mysql_truncate_table no longer exists.
sql/sql_partition_admin.cc:
  Implement the TRUNCATE PARTITION statement.
sql/sql_truncate.cc:
  Change the truncate table implementation to use the new truncate
  handler method and to not rely on row-by-row delete anymore.
  
  The truncate handler method is always invoked with a exclusive
  metadata lock. Also, it is no longer possible to truncate a
  table that is parent in some non-self-referencing foreign key.
storage/archive/ha_archive.cc:
  Rename method as the description indicates that in the future
  this could be a truncate operation.
storage/blackhole/ha_blackhole.cc:
  Implement truncate as no operation for the blackhole engine in
  order to remain compatible with older releases.
storage/federated/ha_federated.cc:
  Introduce truncate method that invokes delete_all_rows.
  This is required to support partition truncate as this
  form of truncate does not implement the drop and recreate
  protocol.
storage/heap/ha_heap.cc:
  Introduce truncate method that invokes delete_all_rows.
  This is required to support partition truncate as this
  form of truncate does not implement the drop and recreate
  protocol.
storage/ibmdb2i/ha_ibmdb2i.cc:
  Introduce truncate method that invokes delete_all_rows.
  This is required to support partition truncate as this
  form of truncate does not implement the drop and recreate
  protocol.
storage/innobase/handler/ha_innodb.cc:
  Rename delete_all_rows to truncate. InnoDB now does truncate
  under a exclusive metadata lock.
  
  Introduce and reorganize methods used to retrieve the list
  of foreign keys referenced by a or referencing a table.
storage/myisammrg/ha_myisammrg.cc:
  Introduce truncate method that invokes delete_all_rows.
  This is required in order to remain compatible with earlier
  releases where truncate would resort to a row-by-row delete.

e53e16a885 Bug #57002 Assert in upgrade_shared_lock_to_exclusive()
for ALTER TABLE + MERGE tables

The patch for Bug#56292 changed how metadata locks are taken for MERGE
tables. After the patch, locking the MERGE table will also lock the
children tables with the same metadata lock type. This means that 
LOCK TABLES on a MERGE table also will implicitly do LOCK TABLES on
the children tables.

A consequence of this change, is that it is possible to do LOCK TABLES
on a child table both explicitly and implicitly with the same statement
and that these two locks can be of different strength. For example,
LOCK TABLES child READ, merge WRITE.

In LOCK TABLES mode, we are not allowed to take new locks and each
statement must therefore try to find an existing TABLE instance with
a suitable lock. The code that searched for a suitable TABLE instance,
only considered table level locks. If a child table was locked twice,
it was therefore possible for this code to find a TABLE instance with
suitable table level locks but without suitable metadata lock.

This problem caused the assert in upgrade_shared_lock_to_exclusive()
to be triggered as it tried to upgrade a MDL_SHARED lock to
EXCLUSIVE. The problem was a regression caused by the patch for
Bug#56292.

This patch fixes the problem by partially reverting the changes
done by Bug#56292. Now, the children tables will only use the
same metadata lock as the MERGE table for MDL_SHARED_NO_WRITE
when not in locked tables mode. This means that LOCK TABLE
on a MERGE table will not implicitly lock the children tables.
This still fixes the original problem in Bug#56292 without
causing a regression.

Test case added to merge.test.

other connections if we reached a situation where:

1) A connection doing ALTER TABLE can't upgrade to MDL_EXCLUSIVE on the
parent table, but holds TL_READ_NO_INSERT on the child tables.
2) A connection doing DELETE on a child table can't get TL_WRITE on it
since ALTER TABLE holds TL_READ_NO_INSERT.
3) A connection doing SELECT on the parent table can't get TL_READ on 
the child tables since TL_WRITE is ahead in the lock queue, but holds
MDL_SHARED_READ on the parent table preventing ALTER TABLE from upgrading.

For regular tables, this deadlock is avoided by having ALTER TABLE
take a MDL_SHARED_NO_WRITE metadata lock on the table. This prevents
DELETE from acquiring MDL_SHARED_WRITE on the table before ALTER TABLE
tries to upgrade to MDL_EXCLUSIVE. In the example above, SELECT would
therefore not be blocked by the pending DELETE as DELETE would not be
able to enter TL_WRITE in the table lock queue.

This patch fixes the problem for merge tables by using the same metadata
lock type for child tables as for the parent table. The child tables will
in this case therefore be locked with MDL_SHARED_NO_WRITE, preventing
DELETE from acquiring a metadata lock and enter into the table lock queue.

Change in behavior: By taking the same metadata lock for child tables
as for the parent table, LOCK TABLE on the parent table will now also
implicitly lock the child tables. Since LOCK TABLE on the parent table
now takes more than one metadata lock, it is possible for LOCK TABLE
... WRITE on the parent table or child tables to give ER_LOCK_DEADLOCK
error.

Test case added to mdl_sync.test.
Merge.test/.result has been updated to reflect the change to LOCK TABLE.

ecbcddc03d Improved speed of thr_alarm from O(N) to O(1). thr_alarm is used to handle timeouts and kill of connections.
Fixed compiler warnings.
queues.h and queues.c are now based on the UNIREG code and thus made BSD.
Fix code to use new queue() interface. This mostly affects how you access elements in the queue.
If USE_NET_CLEAR is not set, don't clear connection from unexpected characters. This should give a speed up when doing a lot of fast queries.
Fixed some code in ma_ft_boolean_search.c that had not made it from myisam/ft_boolean_search.c


include/queues.h:
  Use UNIREG code base (BSD)
  Changed init_queue() to take all initialization arguments.
  New interface to access elements in queue
include/thr_alarm.h:
  Changed to use time_t instead of ulong (portability)
  Added index_in_queue, to be able to remove random element from queue in O(1)
mysys/queues.c:
  Use UNIREG code base (BSD)
  init_queue() and reinit_queue() now takes more initialization arguments. (No need for init_queue_ex() anymore)
  Now one can tell queue_insert() to store in the element a pointer to where element is in queue. This allows one to remove elements from queue in O(1) instead of O(N)
mysys/thr_alarm.c:
  Use new option in queue() to allow fast removal of elements.
  Do less inside LOCK_alarm mutex.
  This should give a major speed up of thr_alarm usage when there is many threads
sql/create_options.cc:
  Fixed wrong printf
sql/event_queue.cc:
  Use new queue interface()
sql/filesort.cc:
  Use new queue interface()
sql/ha_partition.cc:
  Use new queue interface()
sql/ha_partition.h:
  Fixed compiler warning
sql/item_cmpfunc.cc:
  Fixed compiler warning
sql/item_subselect.cc:
  Use new queue interface()
  Removed not used variable
sql/net_serv.cc:
  If USE_NET_CLEAR is not set, don't clear connection from unexpected characters.
  This should give a speed up when doing a lot of fast queries at the disadvantage that if there is a bug in the client protocol the connection will be dropped instead of being unnoticed.
sql/opt_range.cc:
  Use new queue interface()
  Fixed compiler warnings
sql/uniques.cc:
  Use new queue interface()
storage/maria/ma_ft_boolean_search.c:
  Copy code from myisam/ft_boolean_search.c
  Use new queue interface()

  Use new queue interface()
storage/maria/maria_pack.c:
  Use new queue interface()
  Use queue_fix() instead of own loop to fix queue.
storage/myisam/ft_boolean_search.c:
  Use new queue interface()
storage/myisam/ft_nlq_search.c:
  Use new queue interface()

f56dd32bf7 Bug#34043: Server loops excessively in _checkchunk() when safemalloc is enabled
Essentially, the problem is that safemalloc is excruciatingly
slow as it checks all allocated blocks for overrun at each
memory management primitive, yielding a almost exponential
slowdown for the memory management functions (malloc, realloc,
free). The overrun check basically consists of verifying some
bytes of a block for certain magic keys, which catches some
simple forms of overrun. Another minor problem is violation
of aliasing rules and that its own internal list of blocks
is prone to corruption.

Another issue with safemalloc is rather the maintenance cost
as the tool has a significant impact on the server code.
Given the magnitude of memory debuggers available nowadays,
especially those that are provided with the platform malloc
implementation, maintenance of a in-house and largely obsolete
memory debugger becomes a burden that is not worth the effort
due to its slowness and lack of support for detecting more
common forms of heap corruption.

Since there are third-party tools that can provide the same
functionality at a lower or comparable performance cost, the
solution is to simply remove safemalloc. Third-party tools
can provide the same functionality at a lower or comparable
performance cost. 

The removal of safemalloc also allows a simplification of the
malloc wrappers, removing quite a bit of kludge: redefinition
of my_malloc, my_free and the removal of the unused second
argument of my_free. Since free() always check whether the
supplied pointer is null, redudant checks are also removed.

Also, this patch adds unit testing for my_malloc and moves
my_realloc implementation into the same file as the other
memory allocation primitives.

client/mysqldump.c:
  Pass my_free directly as its signature is compatible with the
  callback type -- which wasn't the case for free_table_ent.

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++.

  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.

05617af025 A fix and a test case for Bug#36171 "CREATE TEMPORARY TABLE and
MERGE engine".
Backport the patch from 6.0 by Ingo Struewing:
revid:ingo.struewing@sun.com-20091028183659-6kmv1k3gdq6cpg4d
Bug#36171 - CREATE TEMPORARY TABLE and MERGE engine

In former MySQL versions, up to 5.1.23/6.0.4 it was possible to create
temporary MERGE tables with non-temporary MyISAM tables.
        
This has been changed in the mentioned version due to Bug 19627
(temporary merge table locking). MERGE children were locked through
the parent table. If the parent was temporary, it was not locked and
so the children were not locked either. Parallel use of the MyISAM
tables corrupted them.
       
Since 6.0.6 (WL 4144 - Lock MERGE engine children), the children are
locked independently from the parent. Now it is possible to allow
non-temporary children with a temporary parent. Even though the
temporary MERGE table itself is not locked, each non-temporary
MyISAM table is locked anyway.
        
NOTE: Behavior change: In 5.1.23/6.0.4 we prohibited non-temporary
children with a temporary MERGE table. Now we re-allow it.
An important side-effect is that temporary tables, which overlay
non-temporary MERGE children, overlay the children in the MERGE table.

1afe6ff03a A test case for Bug#50788 "main.merge fails on HPUX",
and a backport of relevant changes from the 6.0
version of the fix done by Ingo Struewing.
The bug itself was fixed by the patch for Bug#54811.


MyISAMMRG engine would try to use MMAP on its children
even on platforms that don't support it and even if
myisam_use_mmap option was off.
This lead to an infinite hang in INSERT ... SELECT into 
a MyISAMMRG table when the destination MyISAM table
was also selected from.

A bug in duplicate detection fixed by 54811 was essential to 
the hang - when a duplicate is detected, the optimizer 
disables the use of memory mapped files, and it wasn't the case.

The patch below is also to not turn on MMAP on children tables
if myisam_use_mmap is off.
A test case is added to cover MyISAMMRG and myisam_use_mmap
option.


mysql-test/r/merge_mmap.result:
  Result file - Bug#50788.
mysql-test/t/merge_mmap-master.opt:
  An option file for the test for Bug#50788 -- use mmap.
mysql-test/t/merge_mmap.test:
  Try INSERT ... SELECT into a merge table when myisam_use_mmap is on (Bug#50788).

  Fixed misinterpretation of the return value of my_b_read().
storage/myisammrg/ha_myisammrg.cc:
  Skip HA_EXTRA_MMAP if MyISAM memory mapping is disabled.

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

a8c288054e Bug#53445: Build with -Wall and fix warnings that it generates
Fix various mismatches between function's language linkage. Any
particular function that is declared in C++ but should be callable
from C must have C linkage. Note that function types with different
linkages are also distinct. Thus, if a function type is declared in
C code, it will have C linkage (same if declared in a extern "C"
block).

client/mysql.cc:
  Mismatch between prototype and declaration.
client/mysqltest.cc:
  mysqltest used to be C code. Use C linkage where appropriate.
cmd-line-utils/readline/input.c:
  Isolate unreachable code.
include/my_alloc.h:
  Function type must have C linkage.
include/my_base.h:
  Function type must have C linkage.
include/my_global.h:
  Add helper macros to avoid spurious namespace indentation.
include/mysql.h.pp:
  Update ABI file.
mysys/my_gethwaddr.c:
  Remove stray carriage return and fix coding style.
plugin/semisync/semisync_master_plugin.cc:
  Callback function types have C linkage.
plugin/semisync/semisync_slave_plugin.cc:
  Callback function types have C linkage.
sql/derror.cc:
  Expected function type has C linkage.
sql/field.cc:
  Use helper macro and fix indentation.
sql/handler.cc:
  Expected function type has C linkage.
sql/item_sum.cc:
  Correct function linkages. Remove now unnecessary cast.
sql/item_sum.h:
  Add prototypes with the appropriate linkage as otherwise they
  are distinct.
sql/mysqld.cc:
  Wrap functions in C linkage mode.
sql/opt_range.cc:
  C language linkage is ignored for class member functions.
sql/partition_info.cc:
  Add wrapper functions with C linkage for class member functions.
sql/rpl_utility.h:
  Use helper macro and fix indentation.
sql/sql_class.cc:
  Change type of thd argument -- THD is a class.
  Use helper macro and fix indentation.
sql/sql_class.h:
  Change type of thd argument -- THD is a class.
sql/sql_select.cc:
  Expected function type has C linkage.
sql/sql_select.h:
  Move prototype to sql_test.h
sql/sql_show.cc:
  Expected function type has C linkage.
sql/sql_test.cc:
  Fix required function prototype and fix coding style.
sql/sql_test.h:
  Removed unnecessary export and add another.
storage/myisammrg/ha_myisammrg.cc:
  Expected function type has C linkage.
storage/perfschema/pfs.cc:
  PSI headers are declared with C language linkage, which also
  applies to function types.

  BUG#35274 - merge table doesn't need any base tables, gives
              error 124 when key accessed

  SELECT queries that use index against a merge table with empty
  underlying tables list may return with error "Got error 124 from
  storage engine".

  The problem was that wrong error being returned.

    Return "end of file" error instead of "wrong index" error when
    we got a merge table with empty underlying tables list.
  
    In 5.1 we cannot rely on info->open_tables value when checking
    if a merge table has no underlying tables defined.
    Use info->tables instead.

759d5bc535 Another incarnation of the patch for Bug#30708
(make relies GNU extentions). The patch was partially
backport from 6.0.

Original comment:
bug#30708: make relies GNU extensions.  Now that we no longer use
BitKeeper we can safely remove the SCCS handling with no loss of
functionality.
