The policy is not set for 10.2
If it is set, CMake would complain about bundled zlib for which the policy
is not set.
Fix:
- Set policy for 10.2 for the top level project.
For 10.3+ it was already set
- Cleanup zlib to remove unneeded stuff. It is an internal static library,
it needs none of PROJECT, library versioning, RC file on Windows.
The name of the library on Unix does not make any difference, since it is
static and compiled in.

-Wl,-z,relro,-z,now are linker flags and should
be checked as such.
TODO: perform module, exe shared checks separately
rather than a pure linker check.

This is a way do disable DBUG_ENTER()/DBUG_EXIT() stuff which is
needed to dbug trace. Those who doesn't need it may avoid tests
slowdown with -DWITH_DBUG_TRACE=OFF
dbug/tests.c: add define which is neede always in this test
innodb.log_file_name_debug.test: do not depend on DBUG trace stuff
in test
Benchmark results: each test eats less CPU and you can have more
parallel jobs in MTR.

MemorySanitizer is a compile-time instrumentation layer in clang and GCC.
Together with AddressSanitizer mostly makes the run-time instrumentation
of Valgrind redundant. It is a little more tricky to set up, because
running with uninstrumented libraries will lead into false positives.
You will need an instrumented libc++, and you should use
-stdlib=libc++ instead of the default libstdc++. To build the
instrumented library, you can refer to
https://github.com/google/sanitizers/wiki/MemorySanitizerLibcxxHowTo
or you can adapt these steps that worked for me, for clang-8 version 8.0.1:
cd /mariadb
sudo apt source libc++-8-dev
cd llvm-toolchain-8-8.0.1
mkdir libc++msan; cd libc++msan
cmake ../libcxx -DCMAKE_BUILD_TYPE=Release -DLLVM_USE_SANITIZER=Memory \
-DCMAKE_C_COMPILER=clang-8 -DCMAKE_CXX_COMPILER=clang++-8
Then, in your MariaDB build directory, you have to compile with
libc++ and bundled libraries, such as WITH_SSL=bundled, WITH_ZLIB=bundled.
For uninstrumented system libraries, you will get false positives for
uninitialized values. Like this:
cmake -DWITH_MSAN=ON -DWITH_SSL=bundled -DWITH_ZLIB=bundled \
-DCMAKE_CXX_FLAGS='-stdlib=libc++' ..
Note: you should also add -O2 to the compiler options, or you may
get crashes due to stack overflow.
Finally, to run tests, you must replace libc++ with the instrumented one:
LD_LIBRARY_PATH=/mariadb/llvm-toolchain-8-8.0.1/libc++msan/lib \
MSAN_OPTIONS=abort_on_error=1 \
./mtr --big-test --parallel=auto --force --retry=0
Failure to do so will report numerous false positives related to
operations on std::string and the like.
This is work in progress. Some issues will still have to be fixed
for WITH_MSAN to be usable. See MDEV-20377 for details.

Those two may work incorrectly together. Namely, ASAN may produce
false positives or false negatives. For details see
https://github.com/google/sanitizers/wiki/AddressSanitizer#faq
Make SECURITY_HARDENED disabled by default if WITH_ASAN=ON

GitHub uses a library called Licensee to identify a project's license
type. It shows this information in the status bar and via the API if it
can unambiguously identify the license.
This commit modifies a few of MariaDB's docs so that Licensee is able
to recognize the repository's license type. It renames the README's
"License" section to "Licensing" and renames COPYING.thirdparty to
THIRDPARTY.
These changes allow Licensee to bypass both files when it
scans the repo for license files, which thus allows Licensee to
successfully identify the license type of MariaDB as GPL 2.0.

automatic BuildRequires for source RPM: for every FILEPATH and
"Have library XXX" cached variable, detect what rpm package it comes from
and add it to the list of dependencies.
That is, the source RPM will BuildRequire all those packages that
were found by cmake when the source RPM was built. Presumably, our
CMakeLists.txt won't check for libraries that aren't needed for a build.
It supports libraries/executables/files found with
FIND_LIBRARY
FIND_FILE

Disable LOAD DATA LOCAL INFILE suport by default and
auto-enable it for the duration of one query, if the query
string starts with the word "load". In all other cases the application
should enable LOAD DATA LOCAL INFILE support explicitly.

Backport to 5.5
Current MySQL builds, even on Pushbuild, are not reproducible; they return
different results depending on which directory they are built from (and
Pushbuild uses several different directories). This is because absolute paths
leak into debug information, and even worse, __FILE__. The latter moves code
around enough that we've actually seen sysbench changes on the order of 4% in
some tests.
CMake seemingly insists on using absolute paths, but we can insert our own
layer between CMake and GCC to relativize all paths. Also give the right flags
to get debug information reproducible and turn off build stamping. This makes
the mysqld build 100% bit-for-bit reproducible between runs on my machine,
even when run from different directories.

Don't install server files if WITHOUT_SERVER is specified.
"Server files" are defined as files going into the MariaDB-Server RPM,
that is files in the components Server, ManPagesServer, Server_Scripts,
IniFiles, SuportFiles, and Readme.

This reverts commit d39629f01ebdd5b89186e6c8a4a8d3dd528bd26a.
Because running mtr for many hours with no output whatsoever
is not really what we should do.
And in 5.5 `make test` just works anyway, nothing to fix here.

Assign all tests added via MY_ADD_TEST to a bogus default_ignore target,
so that they are not ran by default when doing bare make test. Add default
test named MTR that calls mysql-test-run suite, which is now the single
test run by make test.
In consequence, modified unit/suite.pm to exclude the MTR test and run the
real ctests flagged for default_ignore target, thus no circular
loop.
