- make spider the last plugin to init (doing it the silly way now,
will need refactoring later)
- remove procedures in init queries which requires `initialized` to be
true which happens later in mysqld_main() during acl_init()
- simplification using `if not exists`
- move the udf creations to a background thread
Result: mdev_27233, mdev_29904, mdev_30370 and their variants
pass. mdev-22979 install_db command fails. ALL "NORMAL" tests seem to
be hanging...

thread to spider_db_init()
This is the original fix by nayuta for MDEV-27233, but it fails

For development only - will squash this into another commit later - do
not push.
mdev_27233_v2: a variant of mdev-27233 where the spider plugin is
loaded in during server startup.
mdev_30370: we update this test to use mysqld_cmd instead of the
noisy mysqld_bootstrap_cmd. We have to kill the server first to avoid
"Can't lock aria control file"
With the change in commit c160a115b8b that was pushed to fix
mdev-27233 but later reverted because of mdev-29904, mdev_27233 and
the updated mdev_30370 would pass, but not mdev_27233_v2 ("[ERROR]
SPIDER plugin initialization failed at 'drop procedure if exists
mysql.spider_fix_one_table' by 'Unknown storage engine 'Aria''") or
mdev_30370 if it uses mysqld_bootstrap_cmd (post-test check will fail
when running this case with some other case, e.g. mtr mdev_30370
mdev_29562).

There are several plugins in ha_spider: spider, spider_alloc_mem,
spider_wrapper_protocols, spider_rewrite etc.
INSTALL PLUGIN foo SONAME ha_spider causes all the other ones to be
installed by the init queries where foo is any of the plugins.
This introduces unnecessary complexiy. For example it reads
mysql.plugins to find all other plugins, causing the hack of moving
spider plugin init to a separate thread.
To install all spider related plugins, install soname ha_spider should
be used instead.

Extracted out common subroutines, gave more meaningful names etc,
added comments etc.
Also:
- Documented active servers load balancing reads, and other fields in
SPIDER_SHARE etc.
- Removed commented out code
- Documented and refactored self-reference check
- Removed some unnecessary functions
- Renamed unhelpful root_count
- Refactored spider_get_{sts,crd}, where we turn get_type into an enum
- Cleaned up spider_mbase_handler::show_table_status() and
spider_mbase_handler::show_index()

mtr uses group suffix, but some existing inc and test files use
server_id for expect files. This patch aims to fix that.
For spider:
With this change we will not have to maintain a separate version of
restart_mysqld.inc for spider, that duplicates code, just because
spider tests use different names for expect files, and shutdown_mysqld
requires magical names for them.
With this change spider tests will also be able to use other features
provided by restart_mysqld.inc without code duplication, like the
parameter $restart_parameters (see e.g. the testcase mdev_29904.test
in commit ef1161e5d4f).
Tests run after this change: default, spider, rocksdb, galera, using
the following command
mtr --parallel=auto --force --max-test-fail=0 --skip-core-file
mtr --suite spider,spider/*,spider/*/* \
--skip-test="spider/oracle.*|.*/t\..*" --parallel=auto --big-test \
--force --max-test-fail=0 --skip-core-file
mtr --suite galera --parallel=auto
mtr --suite rocksdb --parallel=auto

This reverts commit 158a58245813b1959d6ee912d77734620c7cf3ba.
In 10.11 the generation of mysql-log-rotate was removed in commit
fd0dcad676e7b8665f5363d97849a20cbb712933
There's no need to ignore files that aren't generated.

Include cppcheck and FlawFinder for SAST scanning.
Ignorelists are present for both, so only new problems will trigger a CI

Often there are small "nitpicky" changes that need to be done to a PR in order to
get it merged. To speed up the merge process, we will ask contributors
if they are ok with the reviewer making those changes.
Other fixups:
Improve PR template rendering in browser's textarea field. Line wrapping at 80
characters provides a bad user experience within the browser, which
handles word wrapping separately. Thus, prefer long lines in this
markdown file.
Remove the "backwards compatibility section". While the contributor
should ideally care about the impact of their patch on the server's
backwards compatibility, this is an advanced topic that is better
presented in a separate document.

Add variable max_used_connections_time to show the time at which
max_used_connections reached its current value. This is useful for
troubleshooting high connection counts. MySQL 8 has this already.

handle_slave_io(), handle_slave_sql(), os_thread_exit():
Remove a redundant pthread_exit(nullptr) call, because it
would cause SIGSEGV.
mysql_print_status(): Add MEM_MAKE_DEFINED() to work around
some missing instrumentation around mallinfo2().
que_graph_free_stat_list(): Invoke que_node_get_next(node) before
que_graph_free_recursive(node). That is the logical and
MSAN_OPTIONS=poison_in_dtor=1 compatible way of freeing memory.
ins_node_t::~ins_node_t(): Invoke mem_heap_free(entry_sys_heap).
que_graph_free_recursive(): Rely on ins_node_t::~ins_node_t().
fts_t::~fts_t(): Invoke mem_heap_free(fts_heap).
fts_free(): Replace with direct calls to fts_t::~fts_t().
The failures in free_root() due to MSAN_OPTIONS=poison_in_dtor=1
will be covered in MDEV-30942.

…with: Test assertion failed
Problem:
=======
Assertion text: 'Value returned by SSS and PS table for Last_Error_Number
should be same.'
Assertion condition: '"1146" = "0"'
Assertion condition, interpolated: '"1146" = "0"'
Assertion result: '0'
Analysis:
========
In parallel replication when slave is started the worker pool gets
activated and it gets cleared when slave stops. Each time the worker pool
gets activated a backup worker pool also gets created to store worker
specific perforance schema information in case of errors. On error, all
relevant information is copied from rpl_parallel_thread to rli and it gets
cleared from thread. Then server waits for all workers to complete their
work, during this stage performance schema table specific worker info is
stored into the backup pool and finally the actual pool gets cleared. If
users query the performance schema table to know the status of workers the
information from backup pool will be used. The test simulates
ER_NO_SUCH_TABLE error and verifies the worker information in pfs table.
Test works fine if execution occurs in following order.
Step 1. Error occurred 'worker information is copied to backup pool'.
Step 2. handle_slave_sql invokes 'rpl_parallel_resize_pool_if_no_slaves' to
deactivate worker pool, it marks the pool->count=0
Step 3. PFS table is queried, since actual pool is deactivated backup pool
information is read.
If the Step 3 happens prior to Step2 the pool is yet to be deactivated and
the actual pool is read, which doesn't have any error details as they were
cleared. Hence test ocasionally fails.
Fix:
===
Upon error mark the back pool as being active so that if PFS table is
quried since the backup pool is flagged as valid its information will be
read, in case it is not flagged regular pool will be read.
This work is one of the last pieces created by the late Sujatha Sivakumar.

Problem:
========
- InnoDB replace statement returns can't find record as result during
bulk insert operation. InnoDB returns DB_END_OF_INDEX blindly when
bulk transaction is visible to current transaction even though
the search tuple is inserted as a part of current replace statement.
Solution:
=========
row_search_mvcc(): InnoDB should allow the transaction to read
all the rows when innodb intends to do any locking on the
record even though bulk insert transaction changes are
visible to the current transaction

buf_dblwr_t::init(), buf_dblwr_t::close(): Cover also write_cond,
which was added in commit a55b951e6082a4ce9a1f2ed5ee176ea7dbbaf1f2
without explicit initialization. On GNU/Linux, PTHREAD_COND_INITIALIZER
is a zero-initializer. That is why the default zero initialization
happened to work on that platform.

btr_cur_upd_rec_in_place(): Avoid calling page_zip_write_rec() if we
are not modifying any fields that are stored in compressed format.
btr_cur_update_in_place_zip_check(): New function to check if a
ROW_FORMAT=COMPRESSED record can actually be updated in place.
btr_cur_pessimistic_update(): If the BTR_KEEP_POS_FLAG is not set
(we are in a ROLLBACK and cannot write any BLOBs), ignore the potential
overflow and let page_zip_reorganize() or page_zip_compress() handle it.
This avoids a failure when an attempted UPDATE of an NULL column to 0 is
rolled back. During the ROLLBACK, we would try to move a non-updated
long column to off-page storage in order to avoid a compression failure
of the ROW_FORMAT=COMPRESSED page.
page_zip_write_trx_id_and_roll_ptr(): Remove an assertion that would fail
in row_upd_rec_in_place() because the uncompressed page would already
have been modified there.

Commit a923d6f49c1ad6fd3f4d6ec02e444c26e4d1dfa8 disabled numeric setting
of character_set_* variables with non-default values:
MariaDB [(none)]> set character_set_client=224;
ERROR 1115 (42000): Unknown character set: '224'
However the corresponding binlog functionality still write numeric
values for log event, and this will break binlog replay if the value is
not default. Now make the server use 'String' type for
'character_set_client' when generating binlog events
Before:
/*!\C utf8mb4 *//*!*/;
SET @@session.character_set_client=224,@@session.collation_connection=224,@@session.collation_server=33/*!*/;
After:
/*!\C utf8mb4 *//*!*/;
SET @@session.character_set_client=utf8mb4,@@session.collation_connection=33,@@session.collation_server=8/*!*/;
Note: prior to the previous commit, setting with '224' or '45' or
'utf8mb4' have the same effect, as they all set the parameter to
'utf8mb4'.

AWK in used in Debian SysV-init and postinst scripts to determine
is there enough space starting MariaDB database or create new
database to target destination.
These AWK scripts can be rewrited to use pure SH or help
using Coreutils which is mandatory for usage of MariaDB currently.
Reasoning behind this is to get rid of one very less used dependency

In commit d6aed21621e438e6135415c0c09fc6adfc0be368 a condition at
the start of buf_read_ahead_random() was refactored. Only the caller
buf_read_recv_pages() was adjusted for this. We must in fact adjust
every caller and make sure that spare blocks will be allocated
while crash recovery is in progress. This is the simplest fix;
ideally recovery would operate on the compressed page frame.
The observed recovery hang occurred because pages 0 and 3 of a
tablespace were being read due to buf_page_get_gen() calls by
trx_resurrect_table_locks() before the log records for these pages
had been applied. In buf_page_t::read_complete() we would skip
the call to recv_recover_page() because no uncompressed page frame
had been allocated for the block.
