Removing redundant space character after the data type comment
in SHOW CREATE TABLE, so the output changes from e.g.:
a TIME /* mariadb-5.3 */ DEFAULT NULL
to
a TIME /* mariadb-5.3 */ DEFAULT NULL
This is a prerequisite for MDEV-19906.
- Making classes Field_time, Field_datetime, Field_timestamp abstract
- Adding instantiable Field_time0, Field_datetime0, Field_timestamp0 classes
- Removing redundant cast in field_conv.cc, item_timefunc.cc, sp.cc in calls for set_time() and get_timestamp()
- Replacing store_TIME() to store_timestamp() in log.cc and removing redundant cast
Assertion failed in wsrep-lib after transaction replay which
failed due to conflict in certification.
- Implemented reproducible test case MDEV-20793 to reproduce the crash.
- Fixed wsrep-lib to deal with certification error during replay.
Cause:
* when autocommit=0 (or transaction is issued by user),
`ha_commit_trans` is called twice on ALTER TABLE, causing a duplicated
insert into `transaction_registry` (ER_DUP_ENTRY).
Solution:
* ALTER TABLE makes an implicit commit by a second call. We actually
need to make an insert only when it is a real commit. So is_real
variable is additionally checked.
Set read_set bitmap for view from the JOIN::all_fields list instead of JOIN::fields_list
as split_sum_func would have added items to the all_fields list.
The issue here is for degenerate joins we should execute the window
function but it is not getting executed in all the cases.
To get the window function values window function needs to be executed
always. This currently does not happen in few cases
where the join would return 0 or 1 row like
1) IMPOSSIBLE WHERE
2) MIN/MAX optimization
3) EMPTY CONST TABLE
The fix is to make sure that window functions get executed
and the temporary table is setup for the execution of window functions
Description:
============
To change 'CONSERVATIVE' @@global.slave_parallel_mode default to 'OPTIMISTIC'
in 10.5.
@sql/sys_vars.cc
Changed default parallel_mode to 'OPTIMISTIC'
@sql/rpl_filter.cc
Changed default parallel_mode to 'OPTIMISTIC'
@sql/mysqld.cc
Removed the initialization of 'SLAVE_PARALLEL_CONSERVATIVE' to
'opt_slave_parallel_mode' variable.
@mysql-test/suite/rpl/t/rpl_parallel_mdev6589.test
@mysql-test/suite/rpl/t/rpl_mdev6386.test
Added 'mtr' suppression to ignore 'ER_PRIOR_COMMIT_FAILED'. In case of
'OPTIMISTIC' mode if a transaction gets killed during "wait_for_prior_commit"
it results in above error "1964". Hence suppression needs to be added for this
error.
@mysql-test/suite/rpl/t/rpl_parallel_conflicts.test
Test has a 'slave.opt' which explicitly sets slave_parallel_mode to
'conservative'. When the test ends this mode conflicts with new default mode.
Hence check test case reports an error. The 'slave.opt' is removed and options
are set and reset within test.
@mysql-test/suite/multi_source/info_logs.result
@mysql-test/suite/multi_source/reset_slave.result
@mysql-test/suite/multi_source/simple.result
Result content mismatch in "show slave status" output. This is expected as new
slave_parallel_mode='OPTIMISTIC'.
@mysql-test/include/check-testcase.test
Updated default 'slave_parallel_mode' to 'optimistic'.
Refactored rpl_parallel.test into following test cases.
Test case 1: @mysql-test/suite/rpl/t/rpl_parallel_domain.test
Test case 2: @mysql-test/suite/rpl/t/rpl_parallel_domain_slave_single_grp.test

item_cmpfunc.h includes pcre2.h, so with the bundled pcre2
it has to be built before anything that includes pcre2.h .
And item_cmpfunc.h is indirectly included everywhere,
also in many plugins.
Somehow Ninja and Makefiles generators can still deduce the
correct build dependencies, but Visual Studio generator cannot.
Two changes:
* move pcre2.h from item_cmpfunc.h to item_cmpfunc.cc
* create an explicit dependency on pcre2 for the server
Item_ref::val_(datetime|time)_packed() erroneously called
(*ref)->val_(datetime|time)_packed().
- Fixing to call (*ref)->val_(datetime|time)_packed_result().
- Backporting Item::val_(datetime|time)_packed_result() from 10.3.
- Fixing Item_field::get_date_result() to handle null_value in the same
way how Item_field::get_date() does.
Remove Query_tables_list::lock_tables_state - it is not used and it causes
errors like this:
sql_lex.h:1675:7: runtime error: load of value 2779096485, which is not a
valid value for type 'enum_lock_tables_state'
Fixed the condition for waking up/creating another thread.
If there is some work to do (if the request queue is not empty),
a thread should be woken or created.
The condition was incorrect since 18c9b34

The query requires 2 temporary tables for execution, the window function
is always attached to the last temporary table, but in this case the
result field of the window function points to the first temporary table
rather than the last one.
Fixed this by not changing window function items with temporary table
items of the first temporary table.
PR#1127: Fix is_check_constraints.result to be compatibile with 10.3
The patch is done according to the original patch for MDEV-14474
1edd09c325 and not one which is merged on server
d526679efd.
This patch includes:
- Rename from `is_check_constraint` to `is_check_constraints` to tests
and results
- Per review, change the order of fields in IS check_constraints table by adding
the column `table_name` before `constraint_name`. According to the standard
2006 there is no `table_name` column.
- Original patch and one in `10.3` supports embedded server this patch doesn't
support. After the merge `10.3` will not support also.
- Don't use patch c8b8b01b61 to change the length of `CHECK_CLAUSE` field
PR#1150: MDEV-18440: Information_schema.check_constraints possible data leak
This patch is extension of PR 1127 and includes:
- Check for table grants
- Additional test according to the MDEV specification
