- InnoDB fails to find the space id from the page0 of
the tablespace. In that case, InnoDB can use
doublewrite buffer to recover the page0 and write
into the file.
- buf_dblwr_t::init_or_load_pages(): Loads only the pages
which are valid.(page lsn >= checkpoint). To do that,
InnoDB has to open the redo log before system
tablespace, read the latest checkpoint information.
recv_dblwr_t::find_first_page():
1) Iterate the doublewrite buffer pages and find the 0th page
2) Read the tablespace flags, space id from the 0th page.
3) Read the 1st, 2nd and 3rd page from tablespace file and
compare the space id with the space id which is stored
in doublewrite buffer.
4) If it matches then we can write into the file.
5) Return space which matches the pages from the file.
SysTablespace::read_lsn_and_check_flags(): Remove the
retry logic for validating the first page. After
restoring the first page from doublewrite buffer,
assign tablespace flags by reading the first page.
recv_recovery_read_max_checkpoint(): Reads the maximum
checkpoint information from log file
recv_recovery_from_checkpoint_start(): Avoid reading
the checkpoint header information from log file
Datafile::validate_first_page(): Throw error in case
of first page validation fails.
The problem is the test is skipped after sourcing include/master-slave.inc.
This leaves the slave threads running after the test is skipped, causing a
following test to fail during rpl setup.
Also rename have_normal_bzip.inc to the more appropriate _zlib.

All Spider tables are recorded in the system table
mysql.spider_tables. Deleting a spider table removes the corresponding
rows from the system table, among other things. This patch makes it so
that if spider could not find any record in the system table to delete
for a given table, it should correctly report that no such Spider
table exists.
A new column was introduced to the show index output in 10.6 in
f691d9865b
Thus we update the check of the number of columns to be at least 13,
rather than exactly 13.
Also backport an err number and format from 10.5 for better error
messages when the column number is wrong.
There are a large number of uses of `strerror` in the codebase,
the local declaration in `storage/connect/tabvct.cpp` is the only one.
Given that none is needed elsewhere, I conclude that this instance can
simply be removed.
initialize THD::rand in THD::init() not in THD::THD(),

Item_float::neg() did not preserve the "presentation" from "this".
So
CAST(-1e0 AS UNSIGNED) -- cast from double to unsigned
changes its meaning to:
CAST(-1 AS UNSIGNED) -- cast signed to undigned
Fixing Item_float::neg() to construct the new value for
Item_float::presentation as follows:
- if the old value starts with minus, then the minus is truncated:
'-2e0' -> '2e0'
- otherwise, minus sign followed by its old value:
'1e0' -> '-1e0'
The bitmap is temporarily flipped to ~0 for the sake of checking all
fields. It needs to be restored because it will be reused in second
and subsequent ps execution.

If a query contained a CTE whose name coincided with the name of one of
the base tables used in the specification of the CTE and the query had at
least two references to this CTE in the specifications of other CTEs then
processing of the query led to unlimited recursion that ultimately caused
a crash of the server.
Any secondary non-recursive reference to a CTE requires creation of a copy
of the CTE specification. All the references to CTEs in this copy must be
resolved. If the specification contains a reference to a base table whose
name coincides with the name of then CTE then it should be ensured that
this reference in no way can be resolved against the name of the CTE.
srv_start(): Move a read only mode startup tweak from
innodb_init_params() to the correct location. Also if
innodb_force_recovery=6 we will disable the doublewrite buffer,
because InnoDB must run in read-only mode to prevent further corruption.
This change only affects debug checks. Whenever srv_read_only_mode holds,
the buf_pool.flush_list will be empty, that is, there will be no writes
of persistent InnoDB data pages.

If a query has a HAVING clause that contains a predicate with a constant
IN subquery whose lef part in its turn is a subquery and the predicate is
subject to pushdown from HAVING to WHERE then execution of the query could
cause a crash of the server.
The cause of the problem was the missing implementation of the walk()
method for the class Item_in_optimizer. As a result in some cases the left
operand of the Item_in_optimizer condition could be traversed twice by
the walk procedure. For many call-back functions used as an argument of
this procedure it does not matter. Yet it matters for the call-back
function cleanup_excluding_immutables_processor() used in pushdown of
predicates from HAVING to WHERE. If the processed item is marked with
the IMMUTABLE_FL flag then the processor just removes this flag, otherwise
it performs cleanup of the item making it unfixed. If an item is marked
with an the IMMUTABLE_FL and it traversed with this processor twice then
it becomes unfixed after the second traversal though the flag indicates
that the item should not be cleaned up.

Problem:
sp_cache erroneously looked up fully qualified SP names (e.g. `DB`.`SP`),
in case insensitive style. It was wrong, because only the "name"
part is always case insensitive, while the "db" part should be compared
according to lower_case_table_names (case sensitively for 0,
case insensitively for 1 and 2).
Fix:
Adding a "casedn_name" parameter make_qname() to tell
if the name part should be lower cased:
`DB1`.`SP` -> "DB1.SP" (when casedn_name=false)
`DB1`.`SP` -> "DB1.sp" (when casedn_name=true)
and using make_qname() with casedn_name=true when creating
sp_cache hash lookup keys.
Details:
As a result, it now works as follows:
- sp_head::m_db is converted to lower case if lower_case_table_names>0
during the sp_name initialization phase. So when make_qname() is called,
sp_head::m_db is already normalized. There are no changes in here.
- The initialization phase of sp_head when creating sp_head::m_qname
now calls make_qname() with casedn_name=true,
so sp_head::m_name gets written to sp_head::m_qname in lower case.
- sp_cache_lookup() now also calls make_qname() with casedn_name=true,
so sp_head::m_name gets written to the temporary lookup key in lower case.
- sp_cache::m_hashtable now uses case sensitive comparison
Part#1 A non-functional change
Changing the signature of Identifier_chain2::make_qname() from
bool make_qname(MEM_ROOT *mem_root, LEX_CSTRING *dst) const;
to
LEX_CSTRING make_qname(MEM_ROOT *mem_root) const;
Now the result is returned as LEX_CSTRING from the function rather than
is passed as a parameter.
The return value {NULL,0} means "EOM".
This is a requirement step to fix and merge easier
MDEV-33019 The database part is not case sensitive in SP names
The original MDEV-31991 commit commend:
- Moving some of Database_qualified_name methods into a new class
Identifier_chain2.
- Changing the data type of the following variables from
Database_qualified_name to Identifier_chain2:
* q_pkg_proc in LEX::call_statement_start()
* q_pkg_func in LEX::make_item_func_call_generic()
Rationale:
The data type of Database_qualified_name::m_db will be changed
to Lex_ident_db soon. So Database_qualified_name won't be able
to store the `pkg.routine` part of `db.pkg.routine` any more,
because `pkg` must not depend on lower-case-table-names.

Attempting to set a SAVEPOINT when one of the involved storage engines
does not support savepoints, raises an error, and results in statement
rollback. If Galera is enabled with binlog emulation, the above
scenario was not handled correctly, and resulted in cluster wide
inconsistency.
The problem was in wsrep_register_binlog_handler(), which is called
towards the beginning of SAVEPOINT execution. This function is
supposed to mark the beginning of statement position in trx cache
through `set_prev_position()`. However, it did so only on condition
that `get_prev_position()` returns `MY_OFF_T_UNDEF`.
This before statement position is typically reset to undefined at the
end of statement in `binlog_commit()` / `binlog_rollback()`.
However that's not the case with Galera and binlog emulation, for
which binlog commit / rollback hooks are not called due to the
optimization that avoids internal 2PC (MDEV-16509).

Donor node now writes new info file: donor_galera_info, which is streamed
along the mariabackup donation to the joiner node. The donor_galera_info
file contains both GTID and gtid domain_id, and joiner will use these to
