Some GSS-API functions like gss_import_name(), gss_release_buffer()
used in plugin/auth_gssapi and libmariadb/plugins/auth are marked
as deprecated in MacOS starting from version 10.14+. It results in
extra warnings output on server building.
To eliminate extra warnings the flag '-Wno-deprecated-declarations'
has been added to compiler invocation string for those source
files that invoke deprecated GSS-API functions.

plugin/auth_pam/mapper/pam_user_map.c on MacOS
Compiler warnings like one listed below are generated during server build on MacOS:
[88%] Building C object plugin/auth_pam/CMakeFiles/pam_user_map.dir/mapper/pam_user_map.c.o
mariadb/server-10.2/plugin/auth_pam/mapper/pam_user_map.c:87:41: error: passing
'gid_t *' (aka 'unsigned int *') to parameter of type 'int *' converts between pointers to integer types
with different sign [-Werror,-Wpointer-sign]
if (getgrouplist(user, user_group_id, loc_groups, &ng) < 0)
^~~~~~~~~~
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.15.sdk/usr/include/unistd.h:650:43: note:
passing argument to parameter here
int getgrouplist(const char *, int, int *, int *);
^
In case MariaDB server is build with -DCMAKE_BUILD_TYPE=Debug it results in
build error.
The reason of compiler warnings is that declaration of the Posix C API function
getgrouplist() on MacOS differs from declaration of getgrouplist() proposed
by Posix.
To suppress this compiler warning cmake configure was adapted to detect what
kind of getgrouplist() function is declared on the build platform and
set the macros HAVE_POSIX_GETGROUPLIST in case the building platform supports
Posix compatible interface for the getgrouplist() function. Depending on
whether this macros is set the compatible type of arguments is used to pass
parameter values to the function.

tablespace upon prepare of mariabackup incremental backup
The problem:
When incremental backup is taken, delta files are created for innodb tables
which are marked as new tables during innodb ddl tracking. When such
tablespace is tried to be opened during prepare in
xb_delta_open_matching_space(), it is "created", i.e.
xb_space_create_file() is invoked, instead of opening, even if
a tablespace with the same name exists in the base backup directory.
xb_space_create_file() writes page 0 header the tablespace.
This header does not contain crypt data, as mariabackup does not have
any information about crypt data in delta file metadata for
tablespaces.
After delta file is applied, recovery process is started. As the
sequence of recovery for different pages is not defined, there can be
the situation when crypt data redo log event is executed after some
other page is read for recovery. When some page is read for recovery, it's
decrypted using crypt data stored in tablespace header in page 0, if
there is no crypt data, the page is not decryped and does not pass corruption
test.
This causes error for incremental backup --prepare for encrypted
tablespaces.
The error is not stable because crypt data redo log event updates crypt
data on page 0, and recovery for different pages can be executed in
undefined order.
The fix:
When delta file is created, the corresponding write filter copies only
the pages which LSN is greater then some incremental LSN. When new file
is created during incremental backup, the LSN of all it's pages must be
greater then incremental LSN, so there is no need to create delta for
such table, we can just copy it completely.
The fix is to copy the whole file which was tracked during incremental backup
with innodb ddl tracker, and copy it to base directory during --prepare
instead of delta applying.
There is also DBUG_EXECUTE_IF() in innodb code to avoid writing redo log
record for crypt data updating on page 0 to make the test case stable.
Note:
The issue is not reproducible in 10.5 as optimized DDL's are deprecated
in 10.5. But the fix is still useful because it allows to decrease
data copy size during backup, as delta file contains some extra info.
The test case should be removed for 10.5 as it will always pass.

When first argument to the JSON_MERGE_PATCH was NULL and second - the
invalid JSON line, the error code was garbage. So it should be set to 0
initially.

Reimplement MDEV-14275 Improving memory utilization for information schema
Postpone temp table instantiation until after setup_fields().
Replace all unused (not marked in read_set) columns in an I_S table
with CHAR(0). This can drastically reduce the footprint of a MEMORY
table (a TABLE_CATALOG alone is 1538 bytes per row).
This does not change the engine. If the table was decided to be Aria
(because of, say, blobs) then after optimization it'll stay Aria
even if all blobs were removed.
Note 1: when transforming table structure, share->blob_fields is
preserved, otherwise Aria might switch from DYNAMIC to STATIC row format
and expect a special field for a deleted mark, which create_tmp_tabe
didn't provide.
Note 2: optimizer was doing handler::info() (to know the number of rows)
before the temp table is populated. That didn't make much sense. Now
it's done before the table is even instantiated. Preserve the old
behavior and report 0 rows.

- Original patch was contributed by Jani Tolonen <jani.k.tolonen@gmail.com>
https://github.com/an3l/server/commits/bb-10.3-anel-MDEV-21786-dump-sequence
which distinguishes data structure (linked list) of sequences from
tables.
- Added standard sql output to prevent future changes
of sequences and disabled locks for sequences.
- Added test case for `MDEV-20070: mysqldump won't work correct on
sequences` where table column depends on sequence value.
- Restore sequence last value in the following way:
- Find `next_not_cached_value` and use it to `setval()`
- We just need for logical restore, so don't execute `setval()`
- `setval()` should be showed also in case of `--no-data` option.

For debug build of MariaDB server running of the following test case
will hit the assert `thd->lex->sql_command == SQLCOM_UPDATE' in the function
check_fields() on attempt to execute the UPDATE statement.
CREATE TABLE t1 (a INT);
UPDATE t1 FOR PORTION OF APPTIME FROM (SELECT 1 FROM t1) TO 2 SET a = 1;
Stack trace to the fired assert statement
DBUG_ASSERT(thd->lex->sql_command == SQLCOM_UPDATE)
listed below:
mysql_execute_command() ->
mysql_multi_update_prepare() -->
Multiupdate_prelocking_strategy::handle_end() -->
check_fiels()
It's worth to note that this stack trace looks like a multi update
statement is being executed. The fired assert is checked inside the
function check_fields() in case table->has_period() returns the value
true that in turns happens when temporal period specified in the UPDATE
statement. Condition specified in the DEBUG_ASSERT statement returns
the false value since the data member thd->lex->sql_command have the
value SQLCOM_UPDATE_MULTI. So, the main question is why a program control
flow go to the path prescribed for handling MULTI update statement
despite of the fact that the ordinary UPDATE statement being executed.
The answer is a way that SQL grammar rules written.
When the statement
UPDATE t1 FOR PORTION OF APPTIME FROM (SELECT 1 FROM t1) TO 2 SET a = 1;
being parsed an action for the rule 'table_primary_ident' (part of this action
is listed below to simplify description) is invoked to handle the table
name 't1' specified in the clause 'SELECT 1 FROM t1'.
table_primary_ident:
table_ident opt_use_partition opt_for_system_time_clause
opt_table_alias_clause opt_key_definition
{
SELECT_LEX *sel= Select;
sel->table_join_options= 0;
if (!($$= Select->add_table_to_list(thd, $1, $4,
This action calls the method st_select_lex::add_table_to_list()
to add the table name 't1' to the list of tables being used by the statement.
Later, an action for the following grammar rule
update_table_list:
table_ident opt_use_partition for_portion_of_time_clause
opt_table_alias_clause opt_key_definition
{
SELECT_LEX *sel= Select;
sel->table_join_options= 0;
if (!($$= Select->add_table_to_list(thd, $1, $4,
is invoked to handle the clause 't1 FOR PORTION OF APPTIME FROM ... TO 2'.
This action also calls the method st_select_lex::add_table_to_list()
to add the table name 't1' to the list of tables being used by the statement.
In result the table name 't1' contained twice in this list.
Presence of duplicate names for the table 't1' in a list of table used by
a statement leads to the fact that the function unique_table() called
from the function mysql_update() returns the value true that forces
implementation of the function mysql_update() to return the value 2 as
a signal to fall through the case boundary of the switch statement placed
in the function mysql_execute_statement() and start handling of the case
for sql_command SQLCOM_UPDATE_MULTI. The compound statement block for the
case SQLCOM_UPDATE_MULTI invokes the function mysql_multi_update_prepare()
that executes the statement
set thd->lex->sql_command= SQLCOM_UPDATE_MULTI;
and after that calls the method
Multiupdate_prelocking_strategy::handle_end(). Finally, this method
invokes the check_field() function and assert is fired.
The above analysis shows that update for a table that simultaneously specified
both as a destination table of UPDATE statement and as a table taking part in
subquery is actually treated by MariaDB server as multi-update statement.
Taking into account that multi-update statement for temporal period
table is not supported yet by MariaDB, correct way to fix the bug is to return
the error ER_NOT_SUPPORTED_YET for this case.

It was only from CMake-3.14.0 that CMAKE_REQUIRED_LINK_OPTIONS
was used in CHECK_CXX_SOURCE_COMPILES. Without this, it could be
the case (as was on OSX) that a flag was never checked in
CHECK_CXX_SOURCE_COMPILES, the CHECK successfully passed, but
failed at link time.
As such we use CMAKE_REQUIRED_LIBRARIES to include the flags to check
as its compatible enough with the cmake versions for non-Windows
compilers/linkers.
Tested on x86_64 with:
* 3.11.4
* 3.17.4

In the future:
* cmake >=3.14.0 can use CMAKE_REQUIRED_LINK_OPTIONS
* cmake >=3.18.0 can use CHECK_LINKER_FLAG (with policy CMP0057 NEW)

Marking of deletion of row in fts index happens twice in
self-referential foreign key relation. So while performing
referential checks of foreign key, InnoDB can avoid updating
of fts index if the foreign key has self-referential relationship.

Test we can ALTER log tables directly when not being written
to.
This removes the contraint in the rpl_mysql_upgrade.test such
that we can run mysql_upgrade --write-binlog all the way
through to a replica. We test this in the replication scenario
where the mysql.{slow,general}_log tables aren't being
written to.

EVEN IF I LOG TO FILE.
Analysis:
----------
MYSQL_UPGRADE of the master breaks the replication when
the query logging is enabled with FILE/NONE 'log-output'
option on the slave.
mysql_upgrade modifies the 'general_log' and 'slow_log'
tables after the logging is disabled as below:
SET @old_log_state = @@global.general_log;
SET GLOBAL general_log = 'OFF';
ALTER TABLE general_log
MODIFY event_time TIMESTAMP NOT NULL,
( .... );
SET GLOBAL general_log = @old_log_state;
and
SET @old_log_state = @@global.slow_query_log;
SET GLOBAL slow_query_log = 'OFF';
ALTER TABLE slow_log
MODIFY start_time TIMESTAMP NOT NULL,
( .... );
SET GLOBAL slow_query_log = @old_log_state;
In the binary log, only the ALTER statements are logged
but not the SET statements which turns ON/OFF the logging.
So when the slave replays the binary log,the ALTER of LOG
tables throws an error since the logging is enabled. Also
the 'log-output' option is not checked to determine
whether to allow/disallow the ALTER operation.
Fix:
----
The 'log-output' option is included in the check while
determining whether the query logging happens using the
log tables.

The crash was caused by improper raising of an error or replication checksum
verification at time of the server initialization. As there is no THD object
associated with the main initializing thread yet the error text should be
assigned with calling a respective macro that is aware of that possibility.
Fixed accordingly.
[At merging to 10.4 the new test result file needs
+# restart: --master_verify_checksum=ON --debug_dbug=+d,corrupt_read_log_event_char
that mtr run will hint on.]

mysys_ssl/openssl.c on MacOS
Compiler warnings like one listed below are generated during server build on MacOS:
In file included from server-10.2-MDEV-23564/mysys_ssl/openssl.c:33:
In file included from /usr/local/include/openssl/evp.h:16:
In file included from /usr/local/include/openssl/bio.h:20:
/usr/local/include/openssl/crypto.h:206:10: warning: 'CRYPTO_cleanup_all_ex_data' macro redefined [-Wmacro-redefined]
^
/mariadb/server-10.2-MDEV-23564/include/ssl_compat.h:46:9: note: previous definition is here
^
In case MariaDB serer is build with -DCMAKE_BUILD_TYPE=Debug it results in
build error.
The reason of compiler warnings is that header file <ssl_compat.h>
included before the openssl system header files. File ssl_compat.h
contains some macros with the same names as SSL API functions declared
in the openssl system header files. It resulted in duplicate
symbols that produces compiler warnings.
To fix the issue the header file ssl_compat.h should be included
after a line where openssl system header is included.

In row_undo_ins_remove_clust_rec() and similar places,
an assertion !node->trx->dict_operation_lock_mode could fail,
because an online ALTER is not allowed to run at the same time
while DDL operations on the table are being rolled back.
This race condition would be fixed by always acquiring an InnoDB
table lock in ha_innobase::prepare_inplace_alter_table() or
prepare_inplace_alter_table_dict(), or by ensuring that recovered
transactions are protected by MDL that would block concurrent DDL
until the rollback has been completed.
This reverts commit 1509363970e9cb574005e3af560299c055dda983
and commit 22c4a7512f8dc3f2d2586a856b362ad97ab2bf7d.

The function innodb_show_mutex_status() is the only ultimate caller of
LatchCounter::iterate() via MutexMonitor::iterate(). Because the call
is not protected by LatchCounter::m_mutex, any mutex_create() or
mutex_free() that is invoked concurrently during the execution, bad
things such as a crash could happen.
The most likely way for this to happen is buffer pool resizing,
which could cause buf_block_t::mutex (which existed before MDEV-15053)
to be created or freed. We could also register InnoDB mutexes in
TrxFactory::init() if trx_pools needs to grow.
The view INFORMATION_SCHEMA.INNODB_MUTEXES is not affected, because it
only displays information about rw-locks, not mutexes.
This commit intentionally touches also MutexMonitor::iterate()
and the only code that interfaces with LatchCounter::iterate()
to make it clearer for future readers that the scattered code
that is obfuscated by templates belongs together.

To fix this, it is necessary to add an option to exclude the
database with the name "lost+found" from processing (the database
name will be checked by the check_if_skip_database_by_path() or
by the check_if_skip_database() function, and as a result
"lost+found" will be skipped).
In addition, it is necessary to slightly modify the verification
logic in the check_if_skip_database() function.
Also added a new test galera_sst_mariabackup_lost_found.test
