On creation of a VIEW that depends on a stored routine an instance of
the class Item_func_sp is allocated on a memory root of SP statement.
It happens since mysql_make_view() calls the method
  THD::activate_stmt_arena_if_needed()
before parsing definition of the view.
On the other hand, when sp_head's rcontext is created an instance of
the class Field referenced by the data member
  Item_func_sp::result_field
is allocated on the Item_func_sp's Query_arena (call arena) that set up
inside the method
  Item_sp::execute_impl
just before calling the method
  sp_head::execute_function()

On return from the method sp_head::execute_function() all items allocated
on the Item_func_sp's Query_arena are released and its memory root is freed
(see implementation of the method Item_sp::execute_impl). As a consequence,
the pointer
  Item_func_sp::result_field
references to the deallocated memory. Later, when the method
  sp_head::execute
cleans up items allocated for just executed SP instruction the method
  Item_func_sp::cleanup is invoked and tries to delete an object referenced
by data member Item_func_sp::result_field that points to already deallocated
memory, that results in a server abnormal termination.

To fix the issue the current active arena shouldn't be switched to
a statement arena inside the function mysql_make_view() that invoked indirectly
by the method sp_head::rcontext_create. It is implemented by introducing
the new Query_arena's state STMT_SP_QUERY_ARGUMENTS that is set when explicit
Query_arena is created for placing SP arguments and other caller's side items
used during SP execution. Then the method THD::activate_stmt_arena_if_needed()
checks Query_arena's state and returns immediately without switching to
statement's arena.

mariadb-install-db --auth-root-authentication-method=normal created 4
root accounts by default, but only two of these had PROXY privilege
granted.

mariadb-install-db (default option
--auth-root-authentication-method=socket) as non-root user also didn't
grant PROXY priv to the created nonroot@localhost user.

To fix this, in mysql_system_tables_data.sql, we re-use tmp_user_nopasswd
as this contains the list of all root users.

REPLACE INTO tmp_proxies_priv SELECT @current_hostname, IFNULL(@auth_root_socket, 'root')
creates the $user@$current_host but will not error if @auth_root_socket
is null. Note @current_hostname lines are filtered out with
--cross-bootstrap in mariadb-install-db so it was needed to include this
expression for consistency.

Like the existing mysql_system_tables.sql is used to create teh
$user@localhost proxies_priv.

Test cases roles.acl_statistics, perfschema,privilege_table_io depends on the number of proxy users.

Removed some redundant hint related string literals from
spd_db_conn.cc

Clean up SPIDER_PARAM_*_[CHAR]LEN[S]

Adding tests covering monitoring_kind=2. What it does is that it reads
from mysql.spider_link_mon_servers with matching db_name, table_name,
link_id, and does not do anything about that...

How monitoring_* can be useful: in the deprecated spider high
availability feature, when one remote fails, spider will try another
remote, which apparently makes use of these table parameters.

A test covering the query_cache_sync table param. Some further tests
on some spider table params.

Wrapper should be case insensitive.

Code documentation on spider priority binary tree.

Add an assertion that static_key_cardinality is always -1. All tests
pass still

This helps eliminate "server exists" failures

Also, spider/bugfix.mdev_29676, when enabled after MDEV-29525 is
pushed will fail because we have not --recorded the result. But the
failure will only emerge when working on MDEV-31138 where we manually
re-enable this test, so let's worry about that then.

Also:
- clean up spider_check_and_get_casual_read_conn() and
  spider_check_and_set_autocommit()
- remove a couple of commented out code blocks

- Remove extra connections in the form of `server_number_1` for the same server

- Remove disconnecting and reconnecting to the same connections,

- Update comments about the above.

This function trivially returns false

The SQL thread and a user connection executing SHOW SLAVE STATUS
have a race condition on Last_SQL_Errno, such that a slave which
previously errored and stopped, on its next start, SHOW SLAVE STATUS
can show that the SQL Thread is running while the previous error is
also showing.

The fix is to move when the last error is cleared when the SQL
thread starts to occur before setting the status of
Slave_SQL_Running.

Thanks to Kristian Nielson for his work diagnosing the problem!

There is a list of plugins in the WiX configuration file for HeidiSQL,

Test case is starting too many servers that are not really
needed for original problem testing. This fix reduces
number of servers to make test case smaller and more
robust.
Signed-off-by: Julius Goryavsky <julius.goryavsky@mariadb.com>

Problem was that if wsrep_notify_cmd was set it was called
with a new status "joined" it tries to connect to the server
to update some table, but the server isn't initialized yet,
it's not listening for connections. So the server waits for the
script to finish, script waits for mariadb client to connect,
and the client cannot connect, because the server isn't listening.

Fix is to call script only when Galera has already formed a
view or when it is synched or donor.

This fix also enables following test cases:
* galera.MW-284
* galera.galera_binlog_checksum
* galera_var_notify_ssl_ipv6

innodb_monitor_validate(): Let item_val_str() allocate the memory
in THD, so that it will be available to innodb_monitor_update().
In this way, there is no need to allocate another buffer, and
no problem if the call to innodb_monitor_update() is skipped due
to an invalid value that is passed to another configuration parameter.

There are some other callers to st_mysql_sys_var::val_str()
that validate configuration parameters that are related to FULLTEXT INDEX,
but they will allocate memory by invoking thd_strmake().

Currently include/have_innodb_4k.inc etc. files only check that the
server is running with the corresponding page size. I think it would
be more convenient if they actually enforced the setting.

The test innodb_zip.index_large_prefix_4k would not run unless it is
invoked as
./mtr --mysqld=--innodb-page-size=4k innodb_zip.index_large_prefix_4k

This test was originally developed to cover an option that was removed
in commit 0c92794d. Starting with
MariaDB Server 10.2, which introduced innodb_default_row_format=dynamic,
the option innodb_large_prefix had become useless.

Let us remove some of the stale tests and adjust the outcome to the
expected behaviour.

Let us avoid inserting the rows fid=714 and fid=715, because we would
evaluate g=NULL for them, and NULL values are not allowed in InnoDB
SPATIAL INDEX.

Also, let the test run on any page size, and on non-debug builds.

ibuf_set_bitmap_for_bulk_load(): Port a bug fix that was made as part of
commit 165564d3 (MDEV-30009)
in MariaDB Server 10.5.19.

Port the test case from MySQL to MariaDB:

MySQL fix Bug#33813951, Change-Id: I2448e3f2f36925fe70d882ae5681a6234f0d5a98.

Function test_simple_temporal() from MySQL ported from C++ to pure C.

This includes one change:
-  DIE_UNLESS(field->type == MYSQL_TYPE_DATETIME);
+  DIE_UNLESS(field->type == MYSQL_TYPE_TIMESTAMP);

The bound param of SELECT ? is TIMESTAMP in this code.
MySQL returns it back as DATETIME. MariaDB preserves TIMESTAMP.

Code packaged for commit by Daniel Black.

The problem was that parallel replication of temporary tables using
statement-based binlogging could overlap the COMMIT in one thread with a DML
or DROP TEMPORARY TABLE in another thread using the same temporary table.
Temporary tables are not safe for concurrent access, so this caused
reference to freed memory and possibly other nastiness.

The fix is to disable the optimisation with overlapping commits of one
transaction with the start of a later transaction, when temporary tables are
in use. Then the following event groups will be blocked from starting until
the one using temporary tables is completed.

This also fixes occasional test failures of rpl.rpl_parallel_temptable seen
in Buildbot.
