- Simplified Chinese translation added
- Character encoding is gdk
-- gdk covers more characters
-- gdk includes both Simplified and Traditional
-- best option I think, may need to work along with other locale
settings
- Other cleanup
-- Within each error, messages are sorted according to language code
-- More consistent formatting (8 spaces proceeding each translation)
-- jps removed as duplicate of jpn translation
This should be a good starting point. More refinement is appreciated,
and needed down the road.
English "containt" (sic) spelling fixes on ER_FK_NO_INDEX_{CHILD,PARENT}
resulting in mtr test case adjustments.

* preserve DESC index property in the parser
* store it in the frm (only for HA_KEY_ALG_BTREE)
* read it from the frm
* show it in SHOW CREATE
* skip DESC indexes in opt_range.cc and opt_sum.cc
* ORDER BY test
This includes a fix of MDEV-27432.
This is loosely based on the InnoDB changes in
mysql/mysql-server@97fd8b1b69
that I had developed in 2015 or 2016.
For each B-tree key field, we will allow a flag ASC/DESC to be associated.
When PRIMARY KEY fields are internally appended to secondary indexes,
the ASC/DESC attribute will be inherited, so that covering index scans
will work as expected.
Note: Until the subsequent commit, the DESC attribute will be ignored
(no HA_REVERSE_SORT flag will be written to .frm files).
dict_field_t::descending: A new flag to denote descending order.
cmp_data(), cmp_dfield_dfield(): Add a new parameter descending.
cmp_dtuple_rec(), cmp_dtuple_rec_with_match(): Add a parameter "index".
dtuple_coll_eq(): Replaces dtuple_coll_cmp().
cmp_dfield_dfield_eq_prefix(): Replaces cmp_dfield_dfield_like_prefix().
dict_index_t::is_btree(): Check whether the index is a regular
B-tree index (not SPATIAL, FULLTEXT, or the ibuf.index,
or a corrupted index.
btr_cur_search_to_nth_level_func(): Only attempt to use
the adaptive hash index if index->is_btree().
This function may also be invoked on ibuf.index, and
cmp_dtuple_rec_with_match_bytes() will no longer work on ibuf.index
because it assumes that the index and record fields exactly match.
The ibuf.index is a special variadic index tree.
Thanks to Thirunarayanan Balathandayuthapani for fixing some bugs:
MDEV-27439, MDEV-27374/MDEV-27445.
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.
innobase_pk_order_preserved(): Treat an added AUTO_INCREMENT
column in the same way as an added existing column.
In either case, the column values are not guaranteed to
be constant, and thus the ordering may change if such a column
is added before any existing PRIMARY KEY columns.
prepare_inplace_alter_table_dict(): Initialize
dict_table_t::persistent_autoinc before invoking
innobase_pk_order_preserved().
This was introduced in 1a7a018939
MDEV-16557 Remove INNOBASE_SHARE::idx_trans_tbl
ha_innobase::innobase_get_index: remove incorrect assertion.
Index nullability is checked in subsequent ifs.
Closes#1079
ha_innobase::prepare_inplace_alter_table(): check max column length for every
index in a table, not just added in this particular ALTER TABLE with ADD INDEX ones.
Problem:
=======
During validation of missing tablespace, missing tablespace id is
being compared with hash table of redo logs (recv_sys->addr_hash). But if the
hash table ran out of memory then there is a possibility that it will not contain
the redo logs of all tablespace. In that case, Server will load the InnoDB
even though there is a missing tablespace.
Solution:
========
If the recv_sys->addr_hash hash table ran out of memory then InnoDB needs
to scan the remaining redo log again to validate the missing tablespace.
Import the changes to innodb.innodb-index innodb.innodb-index-debug
Note: As noted in MDEV-13613, due to the behaviour change in MDEV-11114,
DROP COLUMN will not imply DROP/ADD PRIMARY/UNIQUE KEY, like it does
in MySQL. The tests have been adjusted accordingly.
innodb_file_format=Barracuda is the default in MariaDB 10.2.
Do not set it, because the option will be removed in MariaDB 10.3.
Also, do not set innodb_file_per_table=1 because it is the default.
Note that MDEV-11828 should fix the test innodb.innodb-64k
already in 10.1.
be consistent and don't include the table name into the error message,
no other CREATE TABLE error does it.
(the crash happened, because thd->lex->query_tables was NULL)

MDEV-10547: Test multi_update_innodb fails with InnoDB 5.7
The failure happened because 5.7 has changed the signature of
the bool handler::primary_key_is_clustered() const
virtual function ("const" was added). InnoDB was using the old
signature which caused the function not to be used.
MDEV-10550: Parallel replication lock waits/deadlock handling does not work with InnoDB 5.7
Fixed mutexing problem on lock_trx_handle_wait. Note that
rpl_parallel and rpl_optimistic_parallel tests still
fail.
MDEV-10156 : Group commit tests fail on 10.2 InnoDB (branch bb-10.2-jan)
Reason: incorrect merge
MDEV-10550: Parallel replication can't sync with master in InnoDB 5.7 (branch bb-10.2-jan)
Reason: incorrect merge
MDEV-10134 Add full support for DEFAULT
- Added support for using tables with MySQL 5.7 virtual fields,
including MySQL 5.7 syntax
- Better error messages also for old cases
- CREATE ... SELECT now also updates timestamp columns
- Blob can now have default values
- Added new system variable "check_constraint_checks", to turn of
CHECK constraint checking if needed.
- Removed some engine independent tests in suite vcol to only test myisam
- Moved some tests from 'include' to 't'. Should some day be done for all tests.
- FRM version increased to 11 if one uses virtual fields or constraints
- Changed to use a bitmap to check if a field has got a value, instead of
setting HAS_EXPLICIT_VALUE bit in field flags
- Expressions can now be up to 65K in total
- Ensure we are not refering to uninitialized fields when handling virtual fields or defaults
- Changed check_vcol_func_processor() to return a bitmap of used types
- Had to change some functions that calculated cached value in fix_fields to do
this in val() or getdate() instead.
- store_now_in_TIME() now takes a THD argument
- fill_record() now updates default values
- Add a lookahead for NOT NULL, to be able to handle DEFAULT 1+1 NOT NULL
- Automatically generate a name for constraints that doesn't have a name
- Added support for ALTER TABLE DROP CONSTRAINT
- Ensure that partition functions register virtual fields used. This fixes
some bugs when using virtual fields in a partitioning function
In original code, sometimes one got an automatic DEFAULT value in some cases, in other cases not.
For example:
create table t1 (a int primary key) - No default
create table t2 (a int, primary key(a)) - DEFAULT 0
create table t1 SELECT .... - Default for all fields, even if they where defined as NOT NULL
ALTER TABLE ... MODIFY could sometimes add an unexpected DEFAULT value.
The patch is quite big because we had some many test cases that used
CREATE ... SELECT or CREATE ... (...PRIMARY KEY(xxx)) which doesn't have an automatic DEFAULT anymore.
Other things:
- Removed warnings from InnoDB when waiting from semaphore (got this when testing things with --big)
support ha_innodb.so as a dynamic plugin.
* remove obsolete *,innodb_plugin.rdiff files
* s/--plugin-load=/--plugin-load-add=/
* MYSQL_PLUGIN_IMPORT glob_hostname[]
* use my_error instead of push_warning_printf(ER_DEFAULT)
* don't use tdc_size and tc_size in a module
update test cases (XtraDB is 5.6.14, InnoDB is 5.6.10)
* copy new tests over
* disable some tests for (old) InnoDB
* delete XtraDB tests that no longer apply
small compatibility changes:
* s/HTON_EXTENDED_KEYS/HTON_SUPPORTS_EXTENDED_KEYS/
* revert unnecessary InnoDB changes to make it a bit closer to the upstream
fix XtraDB to compile on Windows (both as a static and a dynamic plugin)
disable XtraDB on Windows (deadlocks) and where no atomic ops are available (e.g. CentOS 5)
storage/innobase/handler/ha_innodb.cc:
revert few unnecessary changes to make it a bit closer to the original InnoDB
storage/innobase/include/univ.i:
correct the version to match what it was merged from
includes:
* remove some remnants of "Bug#14521864: MYSQL 5.1 TO 5.5 BUGS PARTITIONING"
* introduce LOCK_share, now LOCK_ha_data is strictly for engines
* rea_create_table() always creates .par file (even in "frm-only" mode)
* fix a 5.6 bug, temp file leak on dummy ALTER TABLE
Includes 5.6 changesets for:
*****
Fix for BUG#13489996 valgrind:conditional jump or move depends on uninitialised values-field_blob.
blob_ptr_size was not initialized properly: remove this variable.
