The fix for "MDEV-17698 MEMORY engine performance regression"
previously fixed this problem.
- Adding the test for MDEV-17724
- Re-recording wrong results for tests:
* engines/iuds/r/insert_number
* engines/iuds/r/update_delete_number
which started to fail since MDEV-17698

The test innodb.log_file_name_debug failed to ensure that
the bogus redo log record that its debug injection emitted
would be consumed by a redo log checkpoint before running a
subsequent test, which could perform crash recovery.
Add an extra shutdown to ensure that a redo log checkpoint is
generated. In this way, the following will succeed:
./mtr --no-reorder innodb.log_file_name_debug innodb.read_only_recovery

There was a failure in rpl_delayed_slave after recent MDEV-14528 commit.
The parallel applier should not set its
Relay_log::last_master_timestamp from Format-descriptor log event.
The latter may reflect a deep past so Seconds-behind-master will be
computed through it and displayed all time while the first possibly
"slow" group of events is executed.
The main MDEV-14528 is refined, rpl_delayed_slave now passes also
in the parallel mode.

Background: Used encryption key_id is stored to encryption metadata
i.e. crypt_data that is stored on page 0 of the tablespace of the
table. crypt_data is created only if implicit encryption/not encryption
is requested i.e. ENCRYPTED=[YES|NO] table option is used
fil_create_new_single_table_tablespace on fil0fil.cc.
Later if encryption is enabled all tables that use default encryption
mode (i.e. no encryption table option is set) are encrypted with
default encryption key_id that is 1. See fil_crypt_start_encrypting_space on
fil0crypt.cc.
ha_innobase::check_table_options()
If default encryption is used and encryption is disabled, you may
not use nondefault encryption_key_id as it is not stored anywhere.

When replicated events are from Master unaware of MariaDB GTID their handling by
the Parallel slave misses Seconds_Behind_Master updating.
In the bug condition the Show-Slave-Status' field remains unchanged.
Because in such case event execution is sequential the bug
is fixed with deploying the same logics as in the explicit single-threaded mode
with is to set
Relay_log_event::last_master_timestamp
member early at the end of event reading from the relay log.

MySQL bug number 90264
Contribution by Yura Sorokin.
Problem:
File mysys/mf_iocache2.c contains non instrumented file io operations.
This causes inaccurate statistics in PERFORMANCE_SCHEMA.
Solution:
Use the instrumentation apis (mysql_file_tell instead of my_tell, etc).

fix for 2-level ft indexes and boolean search in Aria
|

it's not a (char*) pointer to the buffer as in MyISAM.

Two bugs in Aria, related to 2-level fulltext indexes:
* REPAIR calculated the key number incorrectly
* CHECK copied the key into last_key too early and
checking the second-level btree was overwriting it
|
| | | | |
| | | | |
| | | | |
| | | | | |
Also, add a test for a bug that does not seem to affect MariaDB.

InnoDB internal tables related to FULLTEXT INDEX.
row_rename_table_for_mysql(): Do not attempt to rename the internal

innodb_ft_result_cache_limit max limit
- Backported the MYSQL_SYSVAR_SIZE_T to 10.0
- The parameter innodb_ft_result_cache_limit was only 32 bits wide
also on 64-bit systems. Make it size_t, so that it will be 64 bits
on 64-bit systems.
- Added a test case that show how innodb_ft_result_cache_limit variables
behaves in 32bit and 64 bit system.

The test and also rpl_gtid_delete_domain failed on PPC64 platform
due to an incorrectly specified actual key for searching
in a gtid domain system hash. While the correct size is 32 bits
the supplied value was 8 bytes of long int size on the platform.
The problem became evident thanks to the big endiness which
cut off the *least* significant part of the value field.
Fixed with correcting a dynamic array initialization to hold
now uint32 values as well as the values extraction for
searching in the gtid domain system hash.
A new added test ensures no overflowed values are accepted
for deletion which prevents inadvertent action. Notice though
MariaDB [test]> set @@session.gtid_domain_id=(1 << 32) + 1;
MariaDB [test]> show warnings;

This would happen especially in optimistic parallel replication, where there
is a good chance that a transaction will be rolled back (due to conflicts)
after it has executed record_gtid(). If the transaction did any deletions of
old rows as part of record_gtid(), those deletions will be undone as well.
And the code did not properly ensure that the deletions would be re-tried.
This patch makes record_gtid() remember the list of deletions done as part
of a transaction. Then in rpl_slave_state::update() when the changes have
been committed, we discard the list. However, in case of error and rollback,
in cleanup_context() we will instead put the list back into
rpl_global_gtid_slave_state so that the deletions will be re-tried later.
Probably fixes part of the cause of MDEV-12147 as well.

bitmap_is_set(table->read_set, field_index))' failed on concurrent SELECT and DELETE after RENAME from table with index on virtual column
Race condition. field->flags were copied from s->field->flags during
field->clone(), early in open_table_from_share(). But s->field->flags
were getting their PART_INDIRECT_KEY_FLAG bit much later in
TABLE::mark_columns_used_by_virtual_fields() and only once per share.
If two threads were executing the code between field->clone()

one would get PART_INDIRECT_KEY_FLAG bits in field[].

Bug #27968952 INNODB CRASH/CORRUPTION WITH TEXT PREFIX INDEXES
Problem:
There are two problems:
1. If there is one secondary index on extenally
stored column and another seconday index on virtual column (whose
base column is not externally stored). then while updating seconday
index on vitrual column, virtual column data is replaced by
externally stoared column.
2. In row update operation, node->row contains
shallow copy of virtual data fields. While building an update vector
containing all the fields to be modified, compute virtual column.
which may causes change in virtual data fields in node->row.
In both the above cases, while updating seconday index on virtual
column, couldn't find the row and hit an explicite assert inside
ROW_NOT_FOUND.
Fix:
1. Added check if column is virtual then its ext flag should be ZERO
and virtual column data will not be replaced by offset column data.
2. Deep copy of virtual data fields for node->row.

The setting innodb_safe_truncate=ON reduces compatibility with older
versions of MariaDB and backup tools in two ways.
First, we will be writing TRX_UNDO_RENAME_TABLE records, which older
versions do not know about. These records could be misinterpreted if
a DDL transaction was recovered and would be rolled back.
Such rollback is only possible if the server was killed while
an incomplete DDL transaction was persisted. On transaction completion,
the insert_undo log pages would only be repurposed for new undo log
allocations, and their contents would not matter. So, older versions
will not have a problem with innodb_safe_truncate=ON if the server was
shut down cleanly.
Second, to prevent such recovery failure, innodb_safe_truncate=ON will
cause a modification of the redo log format identifier, which will
prevent older versions from starting up after a crash. MariaDB Server
versions older than 10.2.13 will refuse to start up altogether, even
after clean shutdown.
A server restart with innodb_safe_truncate=OFF will restore compatibility
with older server and backup versions.

--prepare
A prepared backup from Mariabackup does not really need to contain any
redo log file, because all log will have been applied to the data files.
When the user copies a prepared backup to a data directory (overwriting
existing files), it could happen that the data directory already contained
redo log files from the past. mariabackup --copy-back) would delete the
old redo log files, but a user’s own copying script might not do that.
To prevent corruption caused by mixing an old redo log file with data
files from a backup, starting with MDEV-13311, Mariabackup would create
a zero-length ib_logfile0 that would prevent startup.
Actually, there is no need to prevent InnoDB from starting up when a
single zero-length file ib_logfile0 is present. Only if there exist
multiple data files of different lengths, then we should refuse to
start up due to inconsistency. A single zero-length ib_logfile0 should
be treated as if the log files were missing: create new log files
according to the configuration.
open_log_file(): Remove. There is no need to open the log files
at this point, because os_file_get_status() already determined
the size of the file.
innobase_start_or_create_for_mysql(): Move the creation of new
log files a little later, not when finding out that the first log
file does not exist, but after finding out that it does not exist
or it exists as a zero-length file.
