The 10.5 version of the patch.
Removing DEFAULT from INFORMATION_SCHEMA columns.
DEFAULT in read-only tables is rather meaningless.
Upgrade should go smoothly.
Also fixes:
MDEV-20254 Problems with EMPTY_STRING_IS_NULL and I_S tables
This patch changes the main name of 3 byte character set from utf8 to
utf8mb3. New old_mode UTF8_IS_UTF8MB3 is added and set TRUE by default,
so that utf8 would mean utf8mb3. If not set, utf8 would mean utf8mb4.
This feature adds the functionality of ignorability for indexes.
Indexes are not ignored be default.
To control index ignorability explicitly for a new index,
use IGNORE or NOT IGNORE as part of the index definition for
CREATE TABLE, CREATE INDEX, or ALTER TABLE.
Primary keys (explicit or implicit) cannot be made ignorable.
The table INFORMATION_SCHEMA.STATISTICS get a new column named IGNORED that
would store whether an index needs to be ignored or not.
failed or late ER_PERIOD_FIELD_WRONG_ATTRIBUTES upon attempt to create
existing table
Analysis: Error state is not stored when field is checked in
Table_period_info::check_field()
Fix: Store error state by setting res to true.
- IF EXISTS ends with a list of all not existing object, instead of a
separate note for every not existing object
- Produce a "Note" for all wrongly dropped objects
(like trying to do DROP SEQUENCE for a normal table)
- Do not write existing tables that could not be dropped to binlog
Other things:
MDEV-22820 Bogus "Unknown table" warnings produced upon attempt to drop
parent table referenced by FK
This was caused by an older version of this commit patch and later fixed
MDEV-22199 Add VISIBLE attribute for indexes in CREATE TABLE
This was done to make it easier to read in dumps from MySQL 8.0 generated
with MySQL workbench
Remove usage of deprecated variable storage_engine. It was deprecated in 5.5 but
it never issued a deprecation warning. Make it issue a warning in 10.5.1.
Replaced with default_storage_engine.
- Moved tests depending on utf8 characters from create to create_utf8
- Fixed some tests in create and sp that wrongly tried to create table
from non existing table on existing table. In a later patch we may
first check if table exists, in which case the error message would
change.
- Updated results for partition_debug_tokudb
