Its important to fail early and only contine with the include after
the boost version check succeeds.
Needs to succeed on ealier verisons too so can't just fail if too new.
As such, do a version check.
This commit fixes the following issues:
- memory leak checking enabled for mysqltest. This cover all cases except
calls to 'die()' that only happens in case of internal failures in
mysqltest. die() is not called anymore in the result files differs.
- One can now run mtr --embedded without failures (this crashed or hang
before)
- cleanup_and_exit() has a new parameter that indicates that it is called
from die(), in which case we should not do memory leak checks. We now
always call cleanup_and_exit() instead of exit() to be able to free up
memory and discover memory leaks.
- Lots of new assert to catch error conditions
- More DBUG statements.
- Fixed that all results are freed in mysqltest (Fixed a memory leak in
mysqltest when using prepared statements).
- Fixed race condition in do_stmt_close() that caused embedded server
to not free memory. (Memory leak in mysqltest with embedded server).
- Fixed two memory leaks in embedded server when using prepared statements.
These memory leaks caused timeout hangs in mtr when server was compiled
with safemalloc. This issue was not noticed (except as timeouts) as
memory report checking was done but output of it was disabled.
it seems that the test can get IO thread running or not,
there's a comment about it. Thus stop_slave_io.inc is told
to ignore errors.
Make stop_slave_io.inc also disable warnings in this case,
in particular "1255 Slave already has been stopped"
on a busy system it might take time for buffer_page_written_index_leaf
to reach the correct value. Wait for it.
also, tag identical statements to be different in the result file.
Fix in this commit handles foreign key value appending into write set
so that db and table names are converted from the filepath format
to tablename format. This is compatible with key values appended from
elsewhere in the code base
There is a mtr test galera.galera_table_with_hyphen for regression testing

Item_func_dyncol_create::print_arguments() printed only CHARSET clause
without COLLATE.
Therefore,
HEX(column_create(1,'1212' AS CHAR CHARACTER SET utf8mb3 COLLATE utf8mb3_bin))
inside a VIEW changed to just:
HEX(column_create(1,'1212' AS CHAR CHARACTER SET utf8mb3))
which changed the collation ID seen in the HEX output.
Note, the collation ID inside column_create() is not really much important.
(It's only important what the character set is).
And for COLLATE, the more important thing is what's later written
in the AS clause of COLUMN_GET:
SELECT
COLUMN_GET(
column_create(1,'1212' AS CHAR CHARACTER SET utf8mb3 COLLATE utf8mb3_bin)
column_nr AS type -- this type is more important
);
Still, let's add the COLLATE clause into the COLUMN_CREATE() print output,
although it's not important for now for anything else than just the HEX output.
At least to make VIEW work in a more predictable way with HEX(COLUMN_CREATE()).
Also, in the future we can start using somehow the collation ID written inside
COLUMN_CREATE(), for example by making the `AS type` clause optional in
COLUMN_GET():
COLUMN_GET(dyncol_blob, column_nr [AS type]);
instead of:
COLUMN_GET(dyncol_blob, column_nr AS type);
SQL Server compatibility layer may need this for
the SQL_Variant data type support.
The discovered memory leak was introduced by the commit
762bf7a03b
(MDEV-22602 Disable UPDATE CASCADE for SQL constraints)
The reason why a memory leaked on running the test main.constraints
is that a statement arena was used for allocation a memory
for storing a constraint name. A constraint name is an entity having
temporary nature by its design so runtime arena should be used for its
allocation.
Found memory leaks were introduced by the commit
a896bebfa6
MDEV-18844 Implement EXCEPT ALL and INTERSECT ALL operations
and caused by using a statement arena instead a runtime arena for
allocation of objects having temporary life span by their nature.
Aforementioned memory leaks were produced by running queries
that typically use select with intersect, union or table values
constructors.
To fix these memory leaks use the runtime arena for allocation
of Item_field objects used by set operations.
Additionally, OOM handling added on allocation of aforementioned
Item_field objects.
$MYSQL_TZINFO_TO_SQL works by truncating tables. Truncation is an
operation that cannot be done in-place and therefore is fundamentally
incompatible with alter_algorithm='INPLACE'. As a result, we override
the default alter_algorithm setting in tztime.cc to
alter_algorithm='COPY' so that timezones can be loaded regardless
of the previously set alter_algorithm.

perfschema aggregation, like SHOW STATUS, is only statistically correct.
It doesn't use atomics for performance reasons and might miss individual
increments, particularly when two connections are disconnecting at the
same time.
To have stable results tests should avoid doing it.
Item_func_group_concat::print() did not take into account
that Item_func_group_concat::separator can be of a different character set
than the "String *str" (when the printing is being done to).
Therefore, printing did not work correctly for:
- non-ASCII separators when GROUP_CONCAT is done on 8bit data
or multi-byte data with mbminlen==1.
- all separators (even including simple ones like comma)
when GROUP_CONCAT is done on ucs2/utf16/utf32 data (mbminlen>1).
Because of this problem, VIEW definitions did not print correctly to
their FRM files. This later led to a wrong SELECT and SHOW CREATE output.
Fix:
- Adding new String methods:
bool append_for_single_quote_using_mb_wc(const char *str, size_t length,
CHARSET_INFO *cs);
bool append_for_single_quote_opt_convert(const char *str,
size_t length,
CHARSET_INFO *cs)
which perform both escaping and character set conversion at the same time.
- Adding a new String method escaped_wc_for_single_quote(),
to reuse the code between the old and the new methods.
- Fixing Item_func_group_concat::print() to use the new
method append_for_single_quote_opt_convert().
Queries that select concatenated constant strings now have
colname and value that match. For example,
SELECT '123' 'x';
will return a result where the column name and value both
are '123x'.

CapabilityBounding sets require filesystem setcap attributes
for the executable to gain privileges during execution.
A side effect of this however is the getauxvec(AT_SECURE) gets
set, and the secure_getenv from OpenSSL internals on
OPENSSL_CONF environment variable will get ignored (openssl gh issue
21770).
According to capabilities(7), Ambient capabilities don't trigger
ld.so triggering the secure execution mode.

MONITOR_INC_VALUE_CUMULATIVE is a multiline macro, so the second statement
will be executed always, regardless of "if" condition.

Let us skip the recently added test main.mysql-interactive if
an instrumented ncurses library is not available.
In InnoDB, let us work around an uninstrumented libnuma, by
declaring that the objects returned by numa_get_mems_allowed()
are initialized.
Starting with clang-16, MemorySanitizer appears to check that
uninitialized values not be passed by value nor returned.
Previously, it was allowed to copy uninitialized data in such cases.
get_foreign_key_info(): Remove a local variable that was passed
uninitialized to a function.
DsMrr_impl: Initialize key_buffer, because DsMrr_impl::dsmrr_init()
is reading it.
test_bind_result_ext1(): MYSQL_TYPE_LONG is 32 bits, hence we must
use a 32-bit type, such as int. sizeof(long) differs between
LP64 and LLP64 targets.
This patch makes the server wait for the manager thread to actually start
before proceeding with server startup.
Without this, if thread scheduling is really slow and the server shutdowns
quickly, then it is possible that the manager thread is not yet started when
shutdown_performance_schema() is called. If the manager thread starts at just
the wrong moment and just before the main server reaches exit(), the thread
can try to access no longer available performance schema data. This was seen
as occasional assertion in the main.bootstrap test.
As an additional improvement, make sure to run all pending actions before
exiting the manager thread.

eliminate_item_equal() uses quick_fix_field() for Item objects it creates.
It computes some of their attributes on its own (see update_used_tables()
call) but it doesn't update not_null_tables_cache.
Recompute not_null_tables_cache also. Not computing it is currently
harmless, except for producing MSAN error when some other code
propagates the wrong value of not_null_tables_cache to other item.
- Suppress the "Difficult to find free blocks" warning
globally to avoid many different test case failing.
- Demote the error information in validate_first_page() to note.
So first page can recovered from doublewrite buffer and can throw
error in case the page wasn't found in doublewrite buffer.
