Kill check moved from send_data() methids in its wrapper:
send_data_with_check().

Now both offset and limit are stored and do not chenged during execution
(offset is decreased during processing in versions before 10.5).

In commit 0f7732d1d1d898f1a9051858932c18bcc9d6f2b4
we introduced a innodb_checksum_algorithm=full_crc32 combination
to a number of encryption tests, and also fixed the code accordingly.
The default in MariaDB 10.5 is innodb_checksum_algorithm=full_crc32.
In a test merge to 10.5, the test encryption.innodb-redo-badkey failed
once due to a message that had been added in that commit.
Let us introduce a full_crc32 option to that test.
And let us use strict_crc32 and strict_full_crc32 instead of the
non-strict variants, for the previously augmented tests, to be in
line with the earlier tests encryption.corrupted_during_recovery and
encryption.innodb_encrypt_temporary_tables.

btr_page_get_split_rec_to_left(): Assert that in the leftmost leaf page,

In MDEV-11369 (instant ADD COLUMN) in MariaDB Server 10.3,
we introduced the hidden metadata record that must be the
first record in the clustered index if and only if
index->is_instant() holds.
To catch MDEV-19783, in
commit ed0793e096a17955c5a03844b248bcf8303dd335 and
commit 99dc40d6ac2234fa4c990665cc1914c1925cd641
we added some assertions to find cases where
the metadata record is missing while it should not be, or a
record exists when it should not. Those assertions were invalid
when traversing the PAGE_FREE list. That list can contain anything;
we must only be able to determine the successor and the size of
each garbage record in it.
page_validate(), page_simple_validate_old(), page_simple_validate_new():
Do not invoke page_rec_get_next_const() for traversing the PAGE_FREE
list, but instead use a lower-level accessor that does not attempt to
validate the REC_INFO_MIN_REC_FLAG.
page_copy_rec_list_end_no_locks(),
page_copy_rec_list_start(), page_delete_rec_list_start():
Add assertions.
btr_page_get_split_rec_to_left(): Remove a redundant return value,
and make the output parameter the return value.
btr_page_get_split_rec_to_right(), btr_page_split_and_insert(): Clean up.

TABLE::mark_columns_needed_for_update(): use_all_columns() assigns
pointer of all_set into read_set and write_set, but this is not good
since all_set is changed later by
TABLE::mark_columns_used_by_index_no_reset().
Do column_bitmaps_signal() whenever we change read_set/write_set.

cause constraint violation
Constraint check is done on secondary index update.
F.ex. DELETE does row_upd_sec_index_entry() and checks constraints in
row_upd_check_references_constraints(). UPDATE is optimized for the
case when order is not changed (node->cmpl_info & UPD_NODE_NO_ORD_CHANGE)
and doesn't do row_upd_sec_index_entry(), so it doesn't check constraints.
Since for versioned DELETE we do UPDATE actually, but expect behaviour
of DELETE in terms of constraints, we should deny this optimization to
get constraints checked.
Fix wrong referenced table check when versioned DELETE inserts history in parent
table. Set check_ref to false in this case.
Removed unused dup_chk_only argument for row_ins_sec_index_entry() and
added check_ref argument.
MDEV-18057 fix was superseded by this fix and reverted.

When MDEV-12026 introduced innodb_checksum_algorithm=full_crc32 in
MariaDB 10.4, it accidentally added a dependency on buf_page_t::encrypted.
Now that the flag has been removed, we must adjust the page-read routine.
buf_page_io_complete(): When the full_crc32 page checksum matches but the
tablespace ID in the page does not match after decrypting, we should
declare it a decryption failure and suppress the page dump output and
any attempts to re-read the page.

read_statistics_for_tables_if_needed
Regression after 279a907, read_statistics_for_tables_if_needed() was
called after open_normal_and_derived_tables() failure.
Fixed by moving read_statistics_for_tables() call to a branch of
get_schema_stat_record() where result of open_normal_and_derived_tables()
is checked.
Removed THD::force_read_stats, added read_statistics_for_tables() instead.

btr_cur_pessimistic_delete(): code changed in a way that allows
to put more REC_INFO_MIN_REC_FLAG assertions inside btr_set_min_rec_mark().
Without that change tests innodb.innodb-table-online,
innodb.temp_table_savepoint and innodb_zip.prefix_index_liftedlimit fail.
Removed basically duplicated page_zip_validate() calls
which fails because of temporary(!) invariant violation.
That fixed innodb_zip.wl5522_debug_zip and
innodb_zip.prefix_index_liftedlimit

The bug affects MariaDB Server 10.3 or later, but it makes sense
to improve CHECK TABLE in earlier versions already.
page_validate(): Check REC_INFO_MIN_REC_FLAG in the records.
This allows CHECK TABLE to catch more bugs.

Until now, InnoDB inefficiently compared the aligned fields
FIL_PAGE_PREV, FIL_PAGE_NEXT to the byte-order-agnostic value FIL_NULL.
This is a backport of 32170f8c6d55c497ae7a791997e17ff7c992b86f

encrypted binlogs, SHOW BINLOG EVENTS reports the correct one.
Analysis
Mysqlbinlog output for encrypted binary log
#Q> insert into tab1 values (3,'row 003')
#190912 17:36:35 server id 10221 end_log_pos 980 CRC32 0x53bcb3d3 Table_map: `test`.`tab1` mapped to number 19
# at 940
#190912 17:36:35 server id 10221 end_log_pos 1026 CRC32 0xf2ae5136 Write_rows: table id 19 flags: STMT_END_F
Here we can see Table_map_log_event ends at 980 but Next event starts at 940.
And the reason for that is we do not send START_ENCRYPTION_EVENT to the slave
Solution:-
Send Start_encryption_log_event as Ignorable_log_event to slave(mysqlbinlog),
So that mysqlbinlog can update its log_pos.
Since Slave can request multiple FORMAT_DESCRIPTION_EVENT while master does not
have so We only update slave master pos when master actually have the
FORMAT_DESCRIPTION_EVENT. Similar logic should be applied for START_ENCRYPTION_EVENT.
Also added the test case when new server reads the data from old server which
does not send START_ENCRYPTION_EVENT to slave.
Master Slave Upgrade Scenario.
When Slave is updated first, Slave will have extra logic of handling
START_ENCRYPTION_EVENT But master willnot be sending START_ENCRYPTION_EVENT.
So there will be no issue.
When Master is updated first, It will send START_ENCRYPTION_EVENT to
slave , But slave will ignore this event in queue_event.

--prepare --export step
When "--export" mariabackup option is used, mariabackup starts the server in
bootstrap mode to generate *.cfg files for the certain innodb tables.
The started instance of the server reads options from the file, pointed
out in "--defaults-file" mariabackup option.
If the server uses the same config file as mariabackup, and binlog is
switched on in that config file, then "mariabackup --prepare --export"
will create binary log files in the server's binary log directory, what
can cause issues.
The fix is to add "--skip-log-bin" in mysld options when the server is
started to generate *.cfg files.

Fix rpl_skip_error test.
We cant reset Slave_skipped_errors(even with FLUSH STATUS), So instead
of absolute slave_skipped_errors we look for delta of slave_skipped_errors
Fix rpl.rpl_binlog_errors and binlog_encryption.rpl_binlog_errors
We create the $load_file and $load_file2 but we never remove them.
Fix rpl_000011.test
Instead of real value use delta value , Since flush status wont flush
LONGLONG variable.
Fix rpl_row_find_row_debug
Instead of searching whole log_error_ file we will use search_pattern_in_file
which runs pattern search only on latest test run , instead of full file.
Fix rpl_ip_mix rpl_ip_mix2
We should call reset slave all because we also want to reset master_host
otherwise show slave status wont be empty and making repeat N a failure.
Fix rpl_rotate_logs
First we have to remove master.info file (cleanup) and second we have to
call reset slave all because if we do not call reset slave all then we wont
read master.info file beacuse we already have master config in memory.
And this makes start slave to pass , which shoud fail becuase its permision
is 000
Fix circular_serverid0 test
The reason is that ++dbug_rows_event_count == 2 in queue_event does
not take --repeat into account. So I have reseted the dbug_rows_event_count
in if body.
