MemorySanitizer (clang -fsanitize=memory) requires that all code
be compiled with instrumentation enabled. The only exception is the
C runtime library. Failure to use instrumented libraries will cause
bogus messages about memory being uninitialized.
In WITH_MSAN builds, we must avoid calling getservbyname(),
because even though it is a standard library function, it is
not instrumented, not even in clang 10.
Note: Before MariaDB Server 10.5, ./mtr will typically fail
due to the old PCRE library, which was updated in MDEV-14024.
The following cmake options were tested on 10.5
in commit 94d0bb4dbe:

-DCMAKE_C_FLAGS='-march=native -O2' \
-DCMAKE_CXX_FLAGS='-stdlib=libc++ -march=native -O2' \

MEM_MAKE_DEFINED(): An alias for VALGRIND_MAKE_MEM_DEFINED()
and __msan_unpoison().
MEM_GET_VBITS(), MEM_SET_VBITS(): Aliases for
VALGRIND_GET_VBITS(), VALGRIND_SET_VBITS(), __msan_copy_shadow().
InnoDB: Replace the UNIV_MEM_ macros with corresponding MEM_ macros.
ut_crc32_8_hw(), ut_crc32_64_low_hw(): Use the compiler built-in
functions instead of inline assembler when building WITH_MSAN.
This will require at least -msse4.2 when building for IA-32 or AMD64.
The inline assembler would not be instrumented, and would thus cause
bogus failures.
ut_strlcpy(): Replace with the standard function strncpy().
ut_strlcpy_rev(): Define in the same compilation unit where
the only caller resides. Avoid unnecessary definition
in non-debug builds.
mem_heap_dup(): Avoid mem_heap_alloc() and memcpy() of data=NULL, len=0.
trx_undo_report_insert_virtual(), trx_undo_page_report_insert(),
trx_undo_page_report_modify(): Avoid memcpy(ptr, NULL, 0).
dfield_data_is_binary_equal(): Correctly handle data=NULL, len=0.
rec_init_offsets_temp(): Do allow def_val=NULL in the interface.
This clean-up was motivated by WITH_UBSAN, and no bug related to this
was observed in the wild. It should be noted that undefined behaviour
such as memcpy(ptr, NULL, 0) could allow compilers to perform unsafe
optimizations, like it was the case in
commit fc168c3a5e (MDEV-15587).
mem_heap_dup(): Avoid mem_heap_alloc() and memcpy() of data=NULL, len=0.
trx_undo_report_insert_virtual(), trx_undo_page_report_insert(),
trx_undo_page_report_modify(): Avoid memcpy(ptr, NULL, 0).
dfield_data_is_binary_equal(): Correctly handle data=NULL, len=0.

such as memcpy(ptr, NULL, 0) could allow compilers to perform unsafe

Learn both valgrind and asan to catch this bug:
mem_heap_t* heap = mem_heap_create(1024);
byte* p = reinterpret_cast<byte*>(heap) + sizeof(mem_heap_t);
*p = 123;
Overflows of the last allocation in a block will be catched too.
mem_heap_create_block(): poison newly allocated memory
mem_heap_free_heap_top(): Remove UNIV_MEM_ASSERT_W() and unpoison
the memory region first, because part of it may have been poisoned
by an earlier mem_heap_free_top() call.
Poison the address range at the end.
mem_heap_block_free(): Poison the address range at the end.
UNIV_MEM_ASSERT_AND_ALLOC(): Replace with UNIV_MEM_ALLOC().
We want to keep the address ranges poisoned (unaccessible) as
long as possible.
UNIV_MEM_ASSERT_AND_FREE(): Replace with UNIV_MEM_FREE().
Also, remove empty .ic files that were not removed by my MySQL commit.
Problem:
InnoDB used to support a compilation mode that allowed to choose
whether the function definitions in .ic files are to be inlined or not.
This stopped making sense when InnoDB moved to C++ in MySQL 5.6
(and ha_innodb.cc started to #include .ic files), and more so in
MySQL 5.7 when inline methods and functions were introduced
in .h files.
Solution:
Remove all references to UNIV_NONINL and UNIV_MUST_NOT_INLINE from
all files, assuming that the symbols are never defined.
Remove the files fut0fut.cc and ut0byte.cc which only mattered when
UNIV_NONINL was defined.
Define my_thread_id as an unsigned type, to avoid mismatch with
ulonglong. Change some parameters to this type.
Use size_t in a few more places.
Declare many flag constants as unsigned to avoid sign mismatch
when shifting bits or applying the unary ~ operator.
When applying the unary ~ operator to enum constants, explictly
cast the result to an unsigned type, because enum constants can
be treated as signed.
In InnoDB, change the source code line number parameters from
ulint to unsigned type. Also, make some InnoDB functions return
a narrower type (unsigned or uint32_t instead of ulint;
bool instead of ibool).
The InnoDB source code contains quite a few references to a closed-source
hot backup tool which was originally called InnoDB Hot Backup (ibbackup)
and later incorporated in MySQL Enterprise Backup.
The open source backup tool XtraBackup uses the full database for recovery.
So, the references to UNIV_HOTBACKUP are only cluttering the source code.

MDEV-10547: Test multi_update_innodb fails with InnoDB 5.7
The failure happened because 5.7 has changed the signature of
the bool handler::primary_key_is_clustered() const
virtual function ("const" was added). InnoDB was using the old
signature which caused the function not to be used.
MDEV-10550: Parallel replication lock waits/deadlock handling does not work with InnoDB 5.7
Fixed mutexing problem on lock_trx_handle_wait. Note that
rpl_parallel and rpl_optimistic_parallel tests still

Reason: incorrect merge
MEM_HEAP_CREATE_BLOCK()
PROBLEM
-------
If we give start mysqld with the option --innodb_log_buffer_size=50GB
,then mem_area_alloc() function fails to allocate memory and returns
NULL.In debug version we assert at this point,but there is no check in
release version and we get a segmentation fault.
FIX
---
Added a log message saying that we are unable to allocate memory.
After this message we assert.

Changes in the InnoDB codebase required to compile and
integrate the MEB codebase with MySQL 5.5.
@ storage/innobase/btr/btr0btr.c
Excluded buffer pool usage from MEB build.
buf_pool_from_bpage calls are in buf0buf.ic, and
the buffer pool functions from that file are
disabled in MEB.
@ storage/innobase/buf/buf0buf.c
Disabling more buffer pool functions unused in MEB.
@ storage/innobase/dict/dict0dict.c
Disabling dict_ind_free that is unused in MEB.
@ storage/innobase/dict/dict0mem.c
The include
#include "ha_prototypes.h"
Was causing conflicts with definitions in my_global.h

dict_mem_foreign_table_name_lookup_set
function is not there in the current codebase, meaning we do not use it in MEB.
@ storage/innobase/fil/fil0fil.c
The srv_fast_shutdown variable is declared in
srv0srv.c that is not compiled in the
mysqlbackup codebase.
This throws an undeclared error.
From the Manual
---------------
innodb_fast_shutdown
--------------------
The InnoDB shutdown mode. The default value is 1
as of MySQL 3.23.50, which causes a “fast� shutdown
(the normal type of shutdown). If the value is 0,
InnoDB does a full purge and an insert buffer merge
before a shutdown. These operations can take minutes,
or even hours in extreme cases. If the value is 1,
InnoDB skips these operations at shutdown.
This ideally does not matter from mysqlbackup

InnoDB: Remove HAVE_purify, UNIV_INIT_MEM_TO_ZERO, UNIV_SET_MEM_TO_ZERO.
The compile-time setting HAVE_purify can mask potential bugs.

as such in Valgrind-instrumented binaries.
os_mem_alloc_large(), ut_malloc_low(): Remove the parameter set_to_zero.
ut_malloc(): Define as a macro that invokes ut_malloc_low().
buf_pool_init(): Never initialize the buffer pool frames. All pages

mem_heap_alloc(): Never initialize the allocated memory block.
os_mem_alloc_nocache(), ut_test_malloc(): Unused function, remove.

While adding code for the low level read of the AUTOINC value from the index,
the case for MEDIUM ints which are 3 bytes was missed triggering an
assertion.
Bug #30907: Regression: "--innodb_autoinc_lock_mode=0" (off) not same as older releases
We don't rely on *first_value to be 0 when checking whether
get_auto_increment() has been invoked for the first time in a multi-row

Merge a change from MySQL AB:
ChangeSet@1.2536.50.1 2007-08-02 12:45:56-07:00 igor@mysql.com
Fixed bug#28404.
This patch adds cost estimation for the queries with ORDER BY / GROUP BY
and LIMIT.
If there was a ref/range access to the table whose rows were required
to be ordered in the result set the optimizer always employed this access
though a scan by a different index that was compatible with the required
order could be cheaper to produce the first L rows of the result set.
Now for such queries the optimizer makes a choice between the cheapest
ref/range accesses not compatible with the given order and index scans
compatible with it.
innodb.result: Adjusted results for test cases affected fy the fix for
bug #28404.
Revision r1781:

AUTOINC locking mechanism.

ha_innodb.cc:
Fix compiler warning: ::get_auto_increment takes a ulonglong
for nb_desired_values, but InnoDB's trx struct stores it as
a ulint (unsigned long). Probably harmless, as a single
statement won't be asking for more than 2^32 rows.
Revision r1987:

deadlock error (transaction rollback) was not being propagated back to MySQL.

Revision r1873:
snprintf() should always return non-negative result. According to
Microsoft documentation about _vscprintf():
If format is a null pointer, the invalid parameter handler is invoked,
as described in Parameter Validation. If execution is allowed to
continue, the functions return -1 and set errno to EINVAL.
The UNIX variant of snprintf() segfaults if format is a NULL pointer
(similar to strlen(NULL) for example), so it is better to conform to
this behavior and crash our custom Windows version instead of
returning -1. Noone would expect -1 to be returned from snprintf().
Cosmetic: Add a space after typecast.
