- JSONCOL::WriteColumn Add types SHORT and BIGINT as accepted
modified: storage/connect/tabjson.cpp
- TDBJSN: Make this type use a separate storage for Json parsing
and retrieve this memory between each rows. This is necessary
to be able to handle big tables. See MDEV-9228.

Avoid calling the wrong AddValue (Windows compiler error ???)
modified: storage/connect/json.h
Fix looping bug in JARRAY::AddValue for arrays having one value.
Fix potential crash in JVALUE::SetValue
modified: storage/connect/json.cpp
Many changes to fix bugs, enhance memory handling and modify Jpath.
In JSNX some functions have been re-written or added to handle new Jpath.
BMX was re-defined to avoid a different size between Windows an Linux.
Jbin memory was fixed to use the proper memory when adding values.
Default pretty value is now 0 instead of 2.
Filename is stored in BSON when IsJson == 2.
BSON size is added to memlen in CalcLen when applicable.
The order or parameter was switch in Json_Object_Grp.
File name argument must be a constant (temporary?)
Json_Set_Item now returns file name when applicable.

WHERE COALESCE(time_column)=TIME('00:00:00')

MDEV-8814 Wrong result for WHERE datetime_column > TIME('00:00:00')
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.
was fixed in HA_CONNECT::CondFilter moving res= pval->val_str(&tmp)
but this was wrong. Now res is only used for strings.

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

Allow user to alter contents of existing table without enforcing
storage engine. However, enforce storage engine on ALTER TABLE

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 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-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.
--encrypt-binlog and --encrypt-tmp-files used to mean
"encrypt XXX if encryption is available, otherwise don't encrypt",
now they mean "encrypt or fail with an error".
