which did not return a correct "end_of_num" pointer in case
of character sets with mbminlen>1 (ucs2, utf16, utf16le, utf32).
The bug caused sporadic test failures on BuildBot,
as well "uninitialized memory read" errors in valgrind builds.

is linked statically and dynamic plugin is not available.

Added tid (thread ID) for system where it is present.

 ps -eL -o tid,pid,command

shows the thread on Linux

MDEV-8468 CAST and INSERT work differently for DECIMAL/INT vs DOUBLE for a string with trailing spaces

Contributed by Bill Parker.

Added check for strndup() return value.

Allow enforce-storage-engine="" option and use that on mysql_install_db
when doing bootstrap.

Updated address parsing logic to include IPv6 format.

    was fixed in HA_CONNECT::CondFilter moving res= pval->val_str(&tmp)
    but this was wrong. Now res is only used for strings.

Fix the test case : switch to save_master_gtid.inc &
sync_with_master_gtid.inc to sync slave with master.

MDEV-8799: Server crashes in btr_defragment_add_index, encryption.innodb-bad-key-change5 and alike fail in buildbot

Problem was unsafe access to NULL pointer. Added additional checks to avoid
access to NULL pointer.

MDEV-8772: Assertion failure in file ha_innodb.cc line 20027 when importing page compressed and encrypted tablespace using incorrect keys

Add error handling to decryp function when decrypt fails during
import.

MDEV-8769: Server crash at file btr0btr.ic line 122 when defragmenting encrypted table using incorrect keys

Add error handling when getting block from encrypted table and decryption
fails.

MDEV-8768: Server crash at file btr0btr.ic line 122 when checking encrypted table using incorrect keys

Add error handling to btr_validate_index when index root block
can't be read because block decryption fails.

Add a new error message when table is encrypted but decryption
fails. Use this new error message on InnoDB/XtraDB.

type_spatial_indexes test is now be re-enabled, and the new result file
can be used for creating engine-specific rdiffs

ALTER TABLE should either bypass enforce-storage-engine, or mysql_upgrade
should refuse to run

Allow user to alter contents of existing table without enforcing
storage engine. However, enforce storage engine on ALTER TABLE
x ENGINE=y;

Adjust the test case to try and avoid some sporadic failures on loaded test
hosts.

The wait for SQL thread to stop may complete before worker threads
have completed.

The problem was fixed earlier by one of the MDEV-8728 subtasks.
Adding a test case only.

Disable IDENTITY_SUBST propagation for ZEROFILL columns,
as discussed with Sergei.

The code was using the wrong variable when comparing the binlog name
for the UNTIL position. This could cause the comparison to fail after
binlog rotation, in turn causing the UNTIL clause to not trigger slave
stop.

MDEV-8755 Equal field propagation is not performed any longer for the IN list when multiple comparison types

MDEV-8712 Wrong result for SELECT..WHERE latin1_bin_column=_latin1'a' AND latin1_bin_column='A'

MDEV-8754 Wrong result for SELECT..WHERE year_field=2020 AND NULLIF(year_field,2010)='2020'
Problems:
1. Item_func_nullif stored a copy of args[0] in a private member m_args0_copy,
   which was invisible for the inherited Item_func menthods, like
   update_used_tables(). As a result, after equal field propagation
   things like Item_func_nullif::const_item() could return wrong result
   and a non-constant NULLIF() was erroneously treated as a constant
   at optimize_cond() time.
   Solution: removing m_args0_copy and storing the return value item
   in args[2] instead.
2. Equal field propagation did not work well for Item_fun_nullif.
   Solution: using ANY_SUBST for args[0] and args[1], as they are in
   comparison, and IDENTITY_SUBST for args[2], as it's not in comparison.

MDEV-8785 Wrong results for EXPLAIN EXTENDED...WHERE NULLIF(latin1_col, _utf8'a' COLLATE utf8_bin) IS NOT NULL
