- Authentication is done using the Hashicorp Vault's token
authentication method;
- If additional client authentication is required, then the
path to the CA authentication bundle file may be passed
as a plugin parameter;
- The creation of the keys and their management is carried
out using the Hashicorp Vault KMS and their tools;
- Key values stored as hexadecimal strings;
- Key values caching is supported.
- Implemented a time-invalidated cache for key values and
for key version numbers received from the Hashicorp Valult
server;
- The plugin uses libcurl (https) as an interface to
the HashiCorp Vault server;
- JSON parsing is performed through the JSON service
(through the include/mysql/service_json.h);
- HashiCorp Vault 1.2.4 was used for development and testing.

commit 1766a18e06a056155031dabefb88ce7f201ad921

fts_optimize_remove_table
- During rollback of InnoDB DDL, it un-necessary removes the table
from fts_optimize_wq. Removal of fts table from fts_optimize_wq when
it has only one fulltext and it is being rollbacked.

log_t::write_checkpoint(): Avoid a race condition with resize_abort()
by loading log_sys.resize_lsn only while holding the locks.
Also, remove an unnecessary write of all outstanding log before
switching log files.
log_t::write_buf(): Mark the entire block in the resize buffer
as initialized, to allow the test innodb.log_file_size_online to pass
when not using the mmap() based interface.

Ever since commit 9608773f75e2ca21491ef6825c3616cdc96d1ca5
we no longer disable innodb_stats_persistent.
Ever since commit 45a05fda27dc7058ce8a89f14b1daa56352adf6b
updates of the InnoDB persistent statistics are covered by MDL.

The first step for deprecating innodb_autoinc_lock_mode(see MDEV-27844) is:
- to switch statement binlog format to ROW if binlog format is MIXED and
the statement changes autoincremented fields
- issue warnings if innodb_autoinc_lock_mode == 2 and binlog format is
STATEMENT

The warning out of OPTIMIZE
Statement is unsafe because it uses a system function
was indeed counterfactual and was resulted by checking an
insufficiently strict property of lex' sql_command_flags.
Fixed with deploying an additional checking of weather
the current sql command that modifes a share->non_determinstic_insert
table is capable of generating ROW format events.
The extra check rules out the unsafety to OPTIMIZE et al, while the
existing check continues to do so to CREATE TABLE (which is
perculiarly tagged as ROW-event generative sql command).
As a side effect sql_sequence.binlog test gets corrected and
binlog_stm_unsafe_warning.test is reinforced to add up
an unsafe CREATE..SELECT test.

zstd-1.1.3 is needed however stretch has only 1.1.2.
Move to distro version based checks as checks against the
apt-cache are unreliable if there is no cache.

Per https://gcc.gnu.org/onlinedocs/gcc/PowerPC-Hardware-Transactional-Memory-Built-in-Functions.html
The .. high level HTM interface .. is common between PowerPC and S/390
Reimplemented the transactional_lock_enabled() detection mechanism for
s390x and POWER based on SIGILL. This also gives non-Linux based unixes
the ability to use HTM. The implementation is based off openssl.
(ref:
https://github.com/openssl/openssl/blob/1c0eede9827b0962f1d752fa4ab5d436fa039da4/crypto/s390xcap.c#L104)
The other ppc64{,le} problems with getauxvec based detection:
* Checking PPC_FEATURE2_HTM_NOSC not needed as we do not do syscalls while
in a transactional state.
* As we don't use, and never should use PPC_FEATURE2_HTM_NO_SUSPEND,
or do syscalls while in transactional state, don't test it.
From: https://www.kernel.org/doc/html/v5.4/powerpc/syscall64-abi.html#transactional-memory
S390x high level __builtin_tbegin functions in the htmxlintrin.h are not
inline. This header file can be included once in the entire set of sources for
a linked target, otherwise duplicate symbols occur. While we could use inline
xabort/xend functions using the low level interface, we keep this the same as
ppc64 for simplicity.
SLES-15, gcc-7, appeared to want everything that included the htmlxlintrin to
be compiled with -mhtm otherwise the __builtin_t{func} where not defined
(in addition to a #ifdef __HTM__ #error). Debian sid gcc-11.2 wanted the same
on ppc64le/ppc64. In general we want to avoid a wide spread use of architecture
cflags as it makes justifications for selective optimizations easier.

buf_page_get_low(): Assert that the block not be read-fixed.
It may be write-fixed while we only hold a shared latch on the page.
Page writes are protected by U latches, which are compatible with S.
In all other places where we assert that the block not be IO-fixed,
we are holding U or X latch, which does prevent concurrent file I/O.

There is only a very small range of gcc compiler versions
that allow the built_{htm} functions to be defined without -mhtm
being specified as a global C{,XX}FLAGS.
Because the design is centered around enable HTM only in the
functional blocks that use it, this breaks on the inclusion
of the htmxlintrin.h header that includes this.
As a partial mitigation, extented to GNU/clang compilers,
transaction functions gain the attribute "hot".
In general the use of htm is around the optimistic
transaction ability of the function. The key part of using the
hot attribute is to place these functions together so that
a maximization of icache, tlb and OS paging can ensure that
these can be ready to execute by any thread/cpu with the
minimum amount of overhead.
POWER is particularly affected here because the xbegin/xend
functions are not inline.
srw_lock.cc requires the -mhtm cflag, both in the storage
engine and the unit tests.

The commits a73acf6c068a39d0bb9437e05b0b60a87e46bba8 and
4d74bac8bc8c14c2b217391b3b8860f3dc701202 updated the PCRE library to a new
version, which in turn requires CMake 3.0. That does not exist in CentOS 7
nor 8, so builds started failing.
Actually the build should not be downloading anything at all. The root
cause was that pcre2-devel was missing from the dependencies. This was
originally not detected, as the download fallback had masked the issue.

MDEV-27025 allows to insert records before the record on which DELETE is
locked, as a result the DELETE misses those records, what causes serious ACID
violation.
Revert MDEV-27025, MDEV-27550. The test which shows the scenario of ACID
violation is added.

btr_cur_optimistic_insert(): Disregard DEBUG_DBUG injection to
invoke btr_page_reorganize() if the page (and the table) is empty.
Otherwise, an assertion would fail in btr_page_reorganize_low()
because PAGE_MAX_TRX_ID is 0 in an empty secondary index leaf page.
