Libmariadb introduced a cmake change that required 3.12 or newer.
Since none of the platforms we currently support have anything lower
than 3.12 available, we should make this a proper requirement for the
Server as well.
All the options that where in buildbot, should
be in the server making it accessible to all
without any special invocation.
If WITH_MSAN=ON, we want to make sure that the
compiler options are supported and it will result
in an error if not supported.
We make the -WITH_MSAN=ON append -stdlib=libc++
to the CXX_FLAGS if supported.
With SECURITY_HARDENING options the bootstrap
currently crashes, so for now, we disable SECRUITY_HARDENING
if there is MSAN enable.
Option WITH_DBUG_TRACE has no effect in MSAN builds.
The final touch to fixing memory leaks for PS/SP. This patch turns on
by default the option WITH_PROTECT_STATEMENT_MEMROOT in order to
build server with memory leaks detection mechanism switched on.
Starting with GCC 10, let us enable _GLIBCXX_DEBUG as well as
_GLIBCXX_ASSERTIONS which have an impact on the GNU libstdc++.
On GCC 8, we observed a compilation failure related to some
missing type conversion.
Even though clang on GNU/Linux would default to using libstdc++
and enabling the debugging seems to work with clang-18, we will
not enable this on clang, in case it would lead to compilation
errors.
For the clang libc++ before clang-15 there was _LIBCPP_DEBUG,
but according to
llvm/llvm-project@f3966eaf86 and
llvm/llvm-project@13ea134323 and
llvm/llvm-project@ff573a42cd it
looks like that for proper results, a specially built debug version
of libc++ would have to be used in order to enable equivalent checks.
This should help catch bugs like the one that
commit 455a15fd06 fixed.

This patch adds support for controlling of memory allocation
done by SP/PS that could happen on second and following executions.
As soon as SP or PS has been executed the first time its memory root
is marked as read only since no further memory allocation should
be performed on it. In case such allocation takes place it leads to
the assert hit for invariant that force no new memory allocations
takes place as soon as the SP/PS has been marked as read only.
The feature for control of memory allocation made on behalf SP/PS
is turned on when both debug build is on and the cmake option
-DWITH_PROTECT_STATEMENT_MEMROOT is set.
The reason for introduction of the new cmake option
-DWITH_PROTECT_STATEMENT_MEMROOT
to control memory allocation of second and following executions of
SP/PS is that for the current server implementation there are too many
places where such memory allocation takes place. As soon as all such
incorrect allocations be fixed the cmake option
-DWITH_PROTECT_STATEMENT_MEMROOT
can be removed and control of memory allocation made on second and
following executions can be turned on only for debug build. Before
every incorrect memory allocation be fixed it makes sense to guard
the checking of memory allocation on read only memory by extra cmake
option else we would get a lot of failing test on buildbot.
Moreover, fixing of all incorrect memory allocations could take pretty
long period of time, so for introducing the feature without necessary
to wait until all places throughout the source code be fixed it makes
sense to add the new cmake option.
