MAP 'REPAIR TABLE' TO RECREATE +ANALYZE FOR ENGINES NOT
SUPPORTING NATIVE REPAIR
Executing 'mysqlcheck --check-upgrade --auto-repair ...' will first issue
'CHECK TABLE FOR UPGRADE' for all tables in the database in order to check if the
tables are compatible with the current version of MySQL. Any tables that are
found incompatible are then upgraded using 'REPAIR TABLE'.
The problem was that some engines (e.g. InnoDB) do not support 'REPAIR TABLE'.
This caused any such tables to be left incompatible. As a result such tables were
not properly fixed by the mysql_upgrade tool.
This patch fixes the problem by first changing 'CHECK TABLE FOR UPGRADE' to return
a different error message if the engine does not support REPAIR. Instead of
"Table upgrade required. Please do "REPAIR TABLE ..." it will report
"Table rebuild required. Please do "ALTER TABLE ... FORCE ..."
Second, the patch changes mysqlcheck to do 'ALTER TABLE ... FORCE' instead of
'REPAIR TABLE' in these cases.
This patch also fixes 'ALTER TABLE ... FORCE' to actually rebuild the table.
This change should be reflected in the documentation. Before this patch,
'ALTER TABLE ... FORCE' was unused (See Bug#11746162)
Test case added to mysqlcheck.test
client/mysqlcheck.c:
Changed mysqlcheck to do 'ALTER TABLE ... FORCE' if
'CHECK TABLE FOR UPGRADE' reports ER_TABLE_NEEDS_REBUILD

Null bytes are restored to "record" buffer, which may
or may not be equal to record buffer for field. Check
null bits in "record" buffer, instead of Field::null_ptr.
storage/archive/ha_archive.cc:
Fixed bug that caused archive.test to fail with: Warning: Found locks from different threads for lock 't2' in 'write' at 'start of release lock'...
The reason was that the TL_WRITE_DELAYED lock was changed to TL_WRITE_ALLOW_WRITE which conflicted with how the lock was used in sql_insert.cc (in particular with thr_upgrade_write_delay_lock())
Reason: inconsistent compilation, federatedx is compiled without SAFEMALLOC
flag, while anything else is compiled with SAFEMALLOC.
As a consequence, my_hash_init used inside federatedx initialization does not
provide correct caller info parameters (file, line) , so they are initialized with
whatever is on stack. When info about allocated memory is output in
COM_DEBUG command, the server crashes trying to output string starting at
0xcccccccccccccccc.
The fix is to remove SAFEMALLOC preprocessor flags
from every CMakeLists.txt, except the top-level one.
Also, SAFEMALLOC is not defined by default now, instead
there is WITH_DEBUG_FULL CMake option which adds
-DSAFEMALLOC to C and C++ flags in debug compilation.
This option is off by default, because
1) Debug C runtime already has heap debugging builtin with
overwrite and leak detection
2)safemalloc considerably slows down the tests.
Note also that
- SAFEMALLOC is gone in MySQL5.5
- On Windows, heap related overflows can also be found using free pageheap utility
(that is also part of application verifier). This is even more efficient if there are no other layers
on top of Windows heap allocator, e.g it is most efficient with release version.

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.
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.

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.

- Removed -%::SCCS/s.% from Makefile.am:s to remove automake warnings
The problem was that the optimize method of the ARCHIVE storage
engine was not preserving the FRM embedded in the ARZ file when
rewriting the ARZ file for optimization. The ARCHIVE engine stores
the FRM in the ARZ file so it can be transferred from machine to
machine without also copying the FRM -- the engine restores the
embedded FRM during discovery.
The solution is to copy over the FRM when rewriting the ARZ file.
In addition, some initial error checking is performed to ensure
garbage is not copied over.
mysql-test/t/archive.test:
Add test case for Bug#45377.
storage/archive/azio.c:
Add error checking to ensure that the I/O operations are
successful.
storage/archive/ha_archive.cc:
Copy over the embedded FRM.
Introduce a MySQL maintainer/developer mode that enables
a set of warning options for the C/C++ compiler. This mode
is intended to help improve the overall quality of the code.
The warning options are:
C_WARNINGS="-Wall -Wextra -Wunused -Wwrite-strings -Werror"
CXX_WARNINGS="$C_WARNINGS -Wno-unused-parameter"
Since -Wall is essentially a moving target, autoconf checks
are not run with warning options enabled, in particualr -Werror.
This decision might be revisited in the future. The patch also
fixes a mistake in the makefiles, where automake CXXFLAGS would
be set to CFLAGS.
config/ac-macros/maintainer.m4:
Add a set of default compiler flags used when in maintainer mode.
configure.in:
Hook into the maintainer mode. Disabled by default.
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.
strict aliasing violations.
Essentially, the problem is that large parts of the server were
developed in simpler times (last decades, pre C99 standard) when
strict aliasing and compilers supporting such optimizations were
rare to non-existent. Thus, when compiling the server with a modern
compiler that uses strict aliasing rules to perform optimizations,
there are several places in the code that might trigger undefined
behavior.
As evinced by some recent bugs, GCC does a somewhat good of job
misoptimizing such code, but on the other hand also gives warnings
about suspicious code. One problem is that the warnings aren't
always accurate, yet we can't afford to just shut them off as we
might miss real cases. False-positive cases are aggravated mostly
by casts that are likely to trigger undefined behavior.
The solution is to start a cleanup process focused on fixing and
reducing the amount of strict-aliasing related warnings produced
by GCC and others compilers. A good deal of noise reduction can
be achieved by just removing useless casts that are product of
historical cruft and are likely to trigger undefined behavior if
dereferenced.

This patch:
- Moves all definitions from the mysql_priv.h file into
header files for the component where the variable is
defined
- Creates header files if the component lacks one
- Eliminates all include directives from mysql_priv.h
- Eliminates all circular include cycles
- Rename time.cc to sql_time.cc
- Rename mysql_priv.h to sql_priv.h
There was no way to repair corrupt ARCHIVE data file,
when unrecoverable data loss is inevitable.
With this fix REPAIR ... EXTENDED attempts to restore
as much rows as possible, ignoring unrecoverable data.
Normal REPAIR is still able to repair meta-data file
only.
