allow injecting extra files into the bintar

Problem:
========
A slave’s relay log format description event is used when
calculating Seconds_Behind_Master (SBM). This forces the SBM
value to spike when processing these events, as their creation
date is set to the timestamp that the IO thread begins.

Solution:
========
When the slave generates a format description event, mark the
event as a relay log event so it does not update the
rli->last_master_timestamp variable.

table: rows are counted twice

Analysis: When the table we are trying to insert into and the SELECT table
are same for INSERT ... SELECT, rows from the SELECT table are copied into
internal temporary table and then to the INSERT table. We only want to
count the rows when we start inserting into the table.
Fix: Reset the counter to 1 before starting to copy from internal temporary
table to select table and then increment the counter.

The problem was earlier fixed by MDEV-21580 and MDEV-22715.

The problem happened because Item_default_value did not overload
properly the val_xxx_result() family methods.

This change backports the patch for:

Analysis: Before PREPARE is executed, binlog_format is STATEMENT.
This PREPARE had SET STATEMENT which sets binlog_format to ROW. Now after
PREPARE is done we reset the binlog_format (back to STATEMENT). But we have
temporary table, it doesn't let changing binlog_format=ROW to
binlog_format=STATEMENT and gives error which goes unreported. This
unreported error eventually causes assertion failure.
Fix: Change return type for LEX::restore_set_statement_var() to bool and
make it return error state.

MDEV-27364 Build from 10.2-10.4 srpm fails on RHEL8 family due to discrepancy in jemalloc requirements

pass jemalloc requirement down to srpm build

If when extracting a range condition for an index from the WHERE condition
Range Optimizer sees that the range condition covers the whole index then
such condition should be discarded because it cannot be used in any range
scan. In some cases Range Optimizer really does it, but there remained some
conditions for which it was not done. As a result the optimizer could
produce index merge plans with the full index scan for one of the indexes
participating in the index merge.
This could be observed in one of the test cases from index_merge1.inc
where a plan with index_merge_sort_union was produced and in the test case
reported for this bug where a plan with index_merge_sort_intersect was
produced. In both cases one of two index scans participating in index merge
ran over the whole index.
The patch slightly changes the original above mentioned test case from
index_merge1.inc to be able to produce an intended plan employing
index_merge_sort_union. The original query was left to show that index
merge is not used for it anymore.
It should be noted that for the plan with index_merge_sort_intersect could
be chosen for execution only due to a defect in the InnoDB code that
returns wrong estimates for the cardinality of big ranges.

This bug led to serious problems in 10.4+ where the optimization using
Rowid filters is employed (see mdev-26446).

This is the first part of the fixes for MDEV-24097. This commit
contains the fixes for instability when testing Galera and when
restarting nodes quickly:

1) Protection against a "stuck" old SST process during the execution
   of the new SST (after restarting the node) is now implemented for
   mariabackup / xtrabackup, which should help to avoid almost all
   conflicts due to the use of the same ports - both during testing
   with mtr, so and when restarting nodes quickly in a production
   environment.
2) Added more protection to scripts against unexpected return of
   the rc != 0 (in the commands for deleting temporary files, etc).
3) Added protection against unexpected crashes during binlog transfer
   (in SST scripts for rsync).
4) Spaces and some special characters in binlog filenames shouldn't
   be a problem now (at the script level).
5) Daemon process termination tracking has been made more robust
   against crashes due to unexpected termination of the previous SST
   process while new scripts are running.
6) Reading ssl encryption parameters has been moved from specific
   SST scripts to a common wsrep_sst_common.sh script, which allows
   unified error handling, unified diagnostics and simplifies script
   revisions in the future.
7) Improved diagnostics of errors related to the use of openssl.
8) Corrections have been made for xtrabackup-v2 (both in tests and in
   the script code) that restore the work of xtrabackup with updated
   versions of innodb.
9) Fixed some tests for galera_3nodes, although the complete solution
   for the problem of starting three nodes at the same time on fast
   machines will be done in a separate commit.

No additional tests are required as this commit fixes problems with
existing tests.

Consider the following use case:
MariaDB [test]> CREATE TABLE t1 (field1 BIGINT DEFAULT -1);
MariaDB [test]> CREATE VIEW v1 AS SELECT DISTINCT field1 FROM t1;

Repeated execution of the following query as a Prepared Statement

MariaDB [test]> PREPARE stmt FROM 'SELECT * FROM v1 WHERE field1 <=> NULL';
MariaDB [test]> EXECUTE stmt;

results in a crash for a server built with DEBUG.

MariaDB [test]> EXECUTE stmt;
ERROR 2013 (HY000): Lost connection to MySQL server during query

Assertion failed: (!result), function convert_const_to_int, file item_cmpfunc.cc, line 476.
Abort trap: 6 (core dumped)

The crash inside the function convert_const_to_int() happens by the reason
that the value -1 is stored in an instance of the class Field_longlong
on restoring its original value in the statement
  result= field->store(orig_field_val, TRUE);
that leads to assigning the value 1 to the variable 'result' with subsequent
crash in the DBUG_ASSERT statement following it
  DBUG_ASSERT(!result);

The main matter here is why this assertion failure happens on the second
execution of the prepared statement and doens't on the first one.
On first handling of the statement
  'EXECUTE stmt;'
a temporary table is created for serving the query involving the view 'v1'.
The table is created by the function create_tmp_table() in the following
calls trace: (trace #1)
  JOIN::prepare (at sql_select.cc:725)
    st_select_lex::handle_derived
      LEX::handle_list_of_derived
        TABLE_LIST::handle_derived
          mysql_handle_single_derived
            mysql_derived_prepare
              select_union::create_result_table
                create_tmp_table

Note, that the data member TABLE::status of a TABLE instance returned by the
function create_tmp_table() has the value 0.

Later the function setup_table_map() is called on the TABLE instance just
created for the sake of the temporary table (calls trace #2 is below):
  JOIN::prepare (at sql_select.cc:737)
    setup_tables_and_check_access
      setup_tables
        setup_table_map
where the data member TABLE::status is set to the value STATUS_NO_RECORD.

After that when execution of the method JOIN::prepare reaches calling of
the function setup_without_group() the following calls trace is invoked
  JOIN::prepare
    setup_without_group
      setup_conds
        Item_func::fix_fields
          Item_func_equal::fix_length_and_dec
            Item_bool_rowready_func2::fix_length_and_dec
              Item_func::setup_args_and_comparator
                Item_func::convert_const_compared_to_int_field
                  convert_const_to_int

There is the following code snippet in the function convert_const_to_int()
at the line item_cmpfunc.cc:448
    bool save_field_value= (field_item->const_item() ||
                            !(field->table->status & STATUS_NO_RECORD));
Since field->table->status has bits STATUS_NO_RECORD set the variable
save_field_value is false and therefore neither the method
Field_longlong::val_int() nor the method Field_longlong::store is called
on the Field instance that has the numeric value -1.
That is the reason why first execution of the Prepared Statement for the query
  'SELECT * FROM v1 WHERE field1 <=> NULL'
is successful.

On second running of the statement 'EXECUTE stmt' a new temporary tables
is also created by running the calls trace #1 but the trace #2 is not executed
by the reason that data member SELECT_LEX::first_cond_optimization has been set
to false on first execution of the prepared statemet (in the method
JOIN::optimize_inner()). As a consequence, the data member TABLE::status for
a temporary table just created doesn't have the flags STATUS_NO_RECORD set and
therefore on re-execution of the prepared statement the methods
Field_longlong::val_int() and Field_longlong::store() are called for the field
having the value -1 and the DBUG_ASSERT(!result) is fired.

To fix the issue the data member TABLE::status has to be assigned the value
STATUS_NO_RECORD in every place where the macros empty_record() is called
to emptify a record for just instantiated TABLE object created on behalf
the new temporary table.

Followup to fix for MDEV-25858: When test_if_skip_sort_order() decides
to use an index to satisfy ORDER BY ... LIMIT clause, it should
disable "Range Checked for Each Record" optimization.

1. Galera SST scripts should use ssl_capath (not ssl_ca) for CA
   directory. The current implementation tries to automatically
   detect the path using the trailing slash in the ssl_ca variable
   value, but this approach is not compatible with the server
   configuration. Now, by analogy with the server, SST scripts
   also use a separate ssl_capath variable. In addition, a similar
   tcapath variable has been added for the old-style configuration
   (in the "sst" section).
2. Openssl utility detection made more reliable.
3. Removed extra spaces in automatically generated command lines -
   to simplify debugging of the SST scripts.
4. In general, the code for detecting the presence or absence of
   auxiliary utilities has been improved - it is made more reliable
   in some configurations (and for shells other than bash).

Per bug report, cycles was woefully insufficient to

MariaDB server crashes on ARM (weak memory model architecture) while
concurrently executing l_find to load node->key and add_to_purgatory
to store node->key = NULL. l_find then uses key (which is NULL), to
pass it to a comparison function.

The specific problem is the out-of-order execution that happens on a
weak memory model architecture. Two essential reorderings are possible,
which need to be prevented.

a) As l_find has no barriers in place between the optimistic read of
the key field lf_hash.cc#L117 and the verification of link lf_hash.cc#L124,
the processor can reorder the load to happen after the while-loop.

In that case, a concurrent thread executing add_to_purgatory on the same
node can be scheduled to store NULL at the key field lf_alloc-pin.c#L253
before key is loaded in l_find.

b) A node is marked as deleted by a CAS in l_delete lf_hash.cc#L247 and
taken off the list with an upfollowing CAS lf_hash.cc#L252. Only if both
CAS succeed, the key field is written to by add_to_purgatory. However,
due to a missing barrier, the relaxed store of key lf_alloc-pin.c#L253
can be moved ahead of the two CAS operations, which makes the value of
the local purgatory list stored by add_to_purgatory visible to all threads
operating on the list. As the node is not marked as deleted yet, the
same error occurs in l_find.

This change three accesses to be atomic.

* optimistic read of key in l_find lf_hash.cc#L117
* read of link for verification lf_hash.cc#L124
* write of key in add_to_purgatory lf_alloc-pin.c#L253

This bug was introduced by commit be00e279
The commit was applied for the task MDEV-6480 that allowed to remove top
level disjuncts from WHERE conditions if the range optimizer evaluated them
as always equal to FALSE/NULL.
If such disjuncts are removed the WHERE condition may become an AND formula
and if this formula contains multiple equalities the field JOIN::item_equal
must be updated to refer to these equalities. The above mentioned commit
forgot to do this and it could cause crashes for some queries.

restore the old behavior where without a debugger mtr does not
wait for mysqld to start. It was broken in feacc0aa

close_connections() in mysqld.cc sends a signal to all threads.
But InnoDB is too busy purging, doesn't react immediately.
close_connections() waits 20 seconds, which isn't enough in this
particular case, and then unlinks all threads from
the list and forcibly closes their vio connection.

InnoDB background  threads have no vio connection to close, but
they're unlinked all the same. So when later they finally notice
the shutdown request and try to unlink themselves, they fail to
assert that they're still linked.

Fix: don't assert_linked, as another thread can unlink this THD anytime

MDEV-20330 Combination of "," (comma), cross join and left join fails to parse

Fix a potential deadlock bug between locks ctrl_mutex and entry->mutex

MySQL documentation isn't going to help our
users and we shouldn't refer to it.

The bug occurs where the float token containing a dot with an 'e'
notation was dropped from the request completely.

This causes a manner of invalid SQL statements like:

select id 1.e, char 10.e(id 2.e), concat 3.e('a'12356.e,'b'1.e,'c'1.1234e)1.e, 12 1.e*2 1.e, 12 1.e/2 1.e, 12 1.e|2 1.e, 12 1.e^2 1.e, 12 1.e%2 1.e, 12 1.e&2 from test;

To be parsed correctly as if it was:

select id, char(id), concat('a','b','c'), 12*2, 12/2, 12|2, 12^2, 12%2, 12&2 from test.test;

This correct parsing occurs when e is followed by any of:

( ) . , | & % * ^ /

this patch moves cpack summury and description for optional packages

Currently, SST scripts assume that the filename specified in
the --log-bin-index argument either does not contain an extension
or uses the standard ".index" extension. Similar assumptions are
used for the log_bin_index parameter read from the configuration
file. This commit adds support for arbitrary extensions for the
index file paths.

If the server is started with the --innodb-force-recovery argument
on the command line, then during SST this argument can be passed to
mariabackup only at the --prepare stage, and accordingly it must be
removed from the --mysqld-args list (and it is not should be passed
to mariabackup otherwise).

This commit fixes a flaw in the SST scripts and add a test that
checks the ability to run the joiner node in a configuration that
uses --innodb-force-recovery=1.
