A reference to a CTE may occur not in the master of the CTE
specification. In this case if the reference to the CTE is
the first one the specification should be detached from its
master and attached to the referencing select.
Also fixed the TYPE column in the lines of the EXPLAIN output
created for CTE tables.
galera_events test shows a regression with the original fix for MW-416
Reason was that Events::drop_event() can be called also from inside event
execution, and there we have a speacial treatment for event, which executes
"DROP EVENT" statement, and runs TOI replication inside the event processing body.
This resulted in executing WSREP_TO_ISOLATION two times for such DROP EVENT statement.
Fix is to call WSREP_TO_ISOLATION_BEGIN only in Events::drop_event()
Changed return code for replicatio error to TRUE.
This is aligned with native mysql convention to return TRUE (defined to 1) or FALSE (defined to 0) from a bool function.
This is wrong, but follows the mysql conventiosn, at least...
Moved TOI replication to happen after ACL checking for commands:
SQLCOM_CREATE_EVENT
SQLCOM_ALTER_EVENT
SQLCOM_DROP_EVENT
SQLCOM_CREATE_VIEW
SQLCOM_CREATE_TRIGGER
SQLCOM_DROP_TRIGGER
SQLCOM_INSTALL_PLUGIN
SQLCOM_UNINSTALL_PLUGIN
Some innobase/xtrabackup changes around from 10.1 are null merged
, in partucular using os_set_file_size to extend tablespaces in server
or mariabackup.
They require non-trivial amount of additional work in 10.2, due to
innobase differences between 10.1 and 10.2
Fixing the asymmetry in the array field_types_merge_rules[][]
which caused data loss when mixing FLOAT + BIGINT in UNIONs
or hybrid functions:
1. FLOAT + INT = DOUBLE
2. FLOAT + BIGINT = FLOAT
3. INT + FLOAT = DOUBLE
4. BIGINT + FLOAT = DOUBLE
Now FLOAT + BIGINT (as in #2) also produces DOUBLE, like the cases #1,#3,#4 do.
'version' variables.
The warnings occur on Windows build, yet they are also are valid
on 32bit Unix.
Fix is to consistently use 64bit integer on all platforms.
- Fix win64 pointer truncation warnings
(usually coming from misusing 0x%lx and long cast in DBUG)
- Also fix printf-format warnings
Make the above mentioned warnings fatal.
- fix pthread_join on Windows to set return value.
Problem:- This crash happens because of thd = NULL , and while checking
for wsrep_on , we no longer check for thd != NULL (MDEV-7955). So this
problem is regression of MDEV-7955. However this patch not only solves
this regression , It solves all regression caused by MDEV-7955 patch.
To get all possible cases when thd can be null , assert(thd)/
assert(trx->mysql_thd) is place just before all wsrep_on and innodb test
suite is run. And the assert which caused failure are removed with a physical
check for thd != NULL. Rest assert are removed. Hopefully this method will
remove all current/potential regression of MDEV-7955.
The issue was that r_loops, r_rows and r_filtered in ANALYZE FORMAT= JSON were not
calculated for the table on which we were performing the MRR scan in the BKA join
Fixed this by adding respective counter in the JOIN_TAB_SCAN_MRR::open and JOIN_TAB_SCAN_MRR::next
Implement Field_timestamp::save_in_field(timestamp_field)
that stores timestamp values without converting them to MYSQL_TIME
and back, because this conversion is lossy around DST change time.
This fixes main.old-mode test.
This is 10.2 version of f8a800bec8
Implement a special Copy_func function for timestamps, that copies
timestamps without converting them to MYSQL_TIME (the conversion is
lossy around DST change time).
This fixes ALTER TABLE part of main.old-mode test.
This is 10.2 version of f4f48e0621
make insert NULL into a timestamp mark the field as having an
explicit value. So that the field won't be assigned the value
again in TABLE::update_default_field()
make Item_func_now_local::save_in_field(timestamp_field) not to go
through MYSQL_TIME - this conversion is lossy around DST change times.
This fixes inserting a default value into a timestamp field.
Implement a special Copy_field method for timestamps, that copies
timestamps without converting them to MYSQL_TIME (the conversion
is lossy around DST change dates).
Binlog_background_thread does not make a call to set_time(), And when
we call binlog_checkpoint_log_event->write() , we write the wrong timestamp.
In this patch we correct this by calling thd->set_time().
followup for 97c2a7354b - don't use thd->is_error(),
the error could've been set before TABLE_LIST::cleanup_items.
Use the error handler to count errors.
This fixes rpl.rpl_row_binlog_max_cache_size - it was failing when
ER_STMT_CACHE_FULL happened duing multi-table update. Because
multi_update::abort_result_set() calls do_updates() to update
as much as possible, so one cannot rely on thd->is_error() after that.
MDEV-13851 Always check table options in ALTER TABLE…ALGORITHM=INPLACE
In the merge of MySQL 5.7.9 to MariaDB 10.2.2, some code was included
that prevents ADD SPATIAL INDEX from being executed with ALGORITHM=INPLACE.
Also, the constant ADD_SPATIAL_INDEX was introduced as an alias
to ADD_INDEX. We will remove that alias now, and properly implement
the same ADD SPATIAL INDEX restrictions as MySQL 5.7 does:
1. table-rebuilding operations are not allowed if SPATIAL INDEX survive it
2. ALTER TABLE…ADD SPATIAL INDEX…LOCK=NONE is not allowed
ha_innobase::prepare_inplace_alter_table(): If the ALTER TABLE
requires actions within InnoDB, enforce the table options (MDEV-13851).
In this way, we will keep denying ADD SPATIAL INDEX for tables
that use encryption (MDEV-11974), even if ALGORITHM=INPLACE is used.
