MDEV-28550: improper handling of replication event group that contains Gtid_log_list_event
If a slave received a fake GLLE event after a GTID event
it would terminate the group. This adds a test for the
previous commit which fixed this issue (939672a).
MDEV-28550 improper handling of replication event group that contains
GTID_LIST_EVENT or INCIDENT_EVENT.
It's legal to have either of the two inside a group. E.g
Gtid_event, Gtid_log_list_event, Query_1, ... Xid_log_event
is permitted.
However, the slave IO thread treated both
as the terminal even when the group represents a DDL query.
That causes a premature Gtid state update so the slave IO would think
the whole group has been collected while in fact Query_1 etc are yet to process.
Fixed with correcting a condition to compute the terminal event
of the group.
Tested with rpl_mysqlbinlog_slave_consistency (of 10.9) and
rpl_gtid_errorlog.test.
MDEV-28310 Missing binlog data for INSERT .. ON DUPLICATE KEY UPDATE
MDEV-21810 MBR: Unexpected "Unsafe statement" warning for unsafe IODKU
MDEV-17614 fixes to replication unsafety for INSERT ON DUP KEY UPDATE
on two or more unique key table left a flaw. The fixes checked the
safety condition per each inserted record with the idea to catch a user-created
value to an autoincrement column and when that succeeds the autoincrement column
would become the source of unsafety too.
It was not expected that after a duplicate error the next record's
write_set may become different and the unsafe decision for that
specific record will be computed to screw the Query's binlogging
state and when @@binlog_format is MIXED nothing gets bin-logged.
This case has been already fixed in 10.5.2 by 91ab42a823 that
relocated/optimized THD::decide_logging_format_low() out of the record insert
loop. The safety decision is computed once and at the right time.
Pertinent parts of the commit are cherry-picked.
Also a spurious warning about unsafety is removed when MIXED
@@binlog_format; original MDEV-17614 test result corrected.
The original test of MDEV-17614 is extended and made more readable.
MDEV-28478: INSERT into SPATIAL INDEX in TEMPORARY table writes log
row_ins_sec_index_entry_low(): If a separate mini-transaction is
needed to adjust the minimum bounding rectangle (MBR) in the parent
page, we must disable redo logging if the table is a temporary table.
For temporary tables, no log is supposed to be written, because
the temporary tablespace will be reinitialized on server restart.
