Bug#15920445 INNODB REPORTS ER_DUP_KEY BEFORE CREATE UNIQUE INDEX COMPLETED
There is a phase during online secondary index creation where the index has
been internally completed inside InnoDB, but does not 'officially' exist yet.
We used to report ER_DUP_KEY in these situations, like this:
ERROR 23000: Can't write; duplicate key in table 't1'
What we should do is to let the 'offending' operation complete, but report an
error to the
ALTER TABLE t1 ADD UNIQUE KEY (c2):
ERROR HY000: Index c2 is corrupted
(This misleading error message should be fixed separately:
Bug#15920713 CREATE UNIQUE INDEX REPORTS ER_INDEX_CORRUPT INSTEAD OF DUPLICATE)
row_ins_sec_index_entry_low(): flag the index corrupted instead of
reporting a duplicate, in case the index has not been published yet.
rb:1614 approved by Jimmy Yang
Problem is that after we have found duplicate key on primary key
we continue to get necessary gap locks in secondary indexes to
block concurrent transactions from inserting the searched records.
However, search from unique index used in foreign key constraint
could return DB_NO_REFERENCED_ROW if INSERT .. ON DUPLICATE KEY UPDATE
does not contain value for foreign key column. In this case
we should return the original DB_DUPLICATE_KEY error instead
of DB_NO_REFERENCED_ROW.
Consider as a example following:
create table child(a int not null primary key,
b int not null,
c int,
unique key (b),
foreign key (b) references
parent (id)) engine=innodb;
insert into child values (1,1,2);
insert into child(a) values (1) on duplicate key update c = 3;
Now primary key value 1 naturally causes duplicate key error that will be
stored on node->duplicate. If there was no duplicate key error, we should
return the actual no referenced row error. As value for column b used in
both unique key and foreign key is not provided, server uses 0 as a
search value. This is naturally, not found leading to DB_NO_REFERENCED_ROW.
But, we should update the row with primay key value 1 anyway as
requested by on duplicate key update clause.
With combination of --log-bin and Galera the server may crash
reporting two characteristic stacks:
/usr/sbin/mysqld(_ZN13MYSQL_BIN_LOG13mark_xid_doneEmb+0xc7)[0x7f182a8e2cb7]
/usr/sbin/mysqld(binlog_background_thread+0x2b5)[0x7f182a8e3275]
or
/usr/sbin/mysqld(_ZN13MYSQL_BIN_LOG21do_checkpoint_requestEm+0x9d)[0x7ff395b2dafd]
/usr/sbin/mysqld(_ZN13MYSQL_BIN_LOG20checkpoint_and_purgeEm+0x11)[0x7ff395b2db91]
/usr/sbin/mysqld(_ZN13MYSQL_BIN_LOG16rotate_and_purgeEb+0xc2)[0x7ff395b300b2]
The reason of the failure appears to be non-matching decrements for
`xid_count_per_binlog::xid_count`
which can occur when a transaction is executed having its connection issued
`SET @@sql_log_bin=0`. In such case the xid count is not incremented but
its decrements still runs to turn `binlog_xid_count_list` into improper state
which the following FLUSH BINARY LOGS exposes through the crash.
*Note_1*: the regression test reuses an existing galera.sql_log_bin
which does not run stably (even in its base form) by mtr with --log-bin.
*Note_2*: 10.0-galera branch is free of this issue having missed MDEV-7205
fixes.
As reported in MDEV-11969 "there's no way to ditch knowledge" about some
domain that is no longer updated on a server. Besides being of annoyance to
clutter output in DBA console stale domains can prevent the slave
to connect the master as MDEV-12012 witnesses.
What domain is obsolete must be evaluated by the user (DBA) according
to whether the domain info is still relevant and will the domain ever
receive any update.
This patch introduces a method to discard obsolete gtid domains from
the server binlog state. The removal requires no event group from such
domain present in existing binlog files though. If there are any the
containing logs must be first PURGEd in order for
FLUSH BINARY LOGS DELETE_DOMAIN_ID=(list-of-domains)
succeed. Otherwise the command returns an error.
The list of obsolete domains can be computed through
intersecting two sets - the earliest (first) binlog's Gtid_list
and the current value of @@global.gtid_binlog_state - and extracting
the domain id components from the intersection list items.
The new DELETE_DOMAIN_ID featured FLUSH continues to rotate binlog
omitting the deleted domains from the active binlog file's Gtid_list.
Notice though when the command is ineffective - that none of requested to delete
domain exists in the binlog state - rotation does not occur.
Obsolete domain deletion is not harmful for connected slaves as long
as master side binlog files *purge* is synchronized with FLUSH-DELETE_DOMAIN_ID.
The slaves must have the last event from purged files processed as usual,
in order not to bump later into requesting a gtid from a file which
was already gone.
While the command is not replicated (as ordinary FLUSH BINLOG LOGS is)
slaves, even though having extra domains, won't suffer from reconnection errors
thanks to master-slave gtid connection protocol allowing the master
to be ignorant about a gtid domain.
Should at failover such slave to be promoted into master role it may run
the ex-master's
FLUSH BINARY LOGS DELETE_DOMAIN_ID=(list-of-domains)
to clean its own binlog state.

uses alias in HAVING when sql_mode = 'ONLY_FULL_GROUP_BY'
This patch corrects the patch for bug#18739: non-standard
HAVING extension was allowed in strict ANSI sql mode
added in 2006 by commit 4b7c4cd27f.
As a result of incompleteness of the fix in the above commit
if a query with GROUP BY contained an aggregate function with an
alias and this alias was used in the HAVING clause of the query
the server reported an error when sql_mode was set to
'ONLY_FULL_GROUP_BY'.
This patch effectively blocks the optimization that uses multiple
equalities for ORDER BY to remove tmp table in the case when
the first table happens to be the result of materialization of
a semi-join nest. Currently there is no code at the execution level
that would support the optimization in this case.
row_log_table_apply_op(): Remove references to dict_table_t::n_vcols.
Virtual column information is no longer being written to the log.
row_log_t: Remove the unused fields n_old_col, n_old_vcol.
When MySQL 5.7 introduced indexed virtual columns, it introduced
several bugs into the online table-rebuilding ALTER, that is,
the row_log_table_apply() family of functions.
The online_log format that was introduced for online table-rebuilding
ALTER in MySQL 5.6 should be sufficient. Ideally, any indexed virtual
column values would be evaluated based on the log records in the temporary
file. There is no need to log virtual column values.
(For ADD INDEX, that is row_log_apply(), we always must log the values of
the keys, no matter if the columns are virtual.)
Because omitting the virtual column values removes any chance of
row_log_table_apply() working with indexed virtual columns, we
will for now refuse LOCK=NONE in table-rebuilding ALTER operations
when indexes on virtual columns exist. This restriction would be
lifted in MDEV-14341.
innobase_indexed_virtual_exist(): New predicate, to determine if
indexed virtual columns exist in a table definition.
ha_innobase::check_if_supported_inplace_alter(): Refuse online rebuild
if indexed virtual columns exist.
rec_get_converted_size_temp_v(), rec_convert_dtuple_to_temp_v(): Remove.
row_log_table_delete(), row_log_table_update(, row_log_table_insert():
Remove parameters for virtual columns.
trx_undo_read_v_rows(): Remove the col_map parameter.
row_log_table_apply(): Do not deal with virtual columns.
Some tests are skipped by checks in suite.pm. It is redundant to
have an sql-level run-time check in the .inc file itself.
In some cases it's not only redundant, but dangerous.
After one bug in 10.2 innodb.create_isl_with_direct failed
to start InnoDB, but the server started fine (just without InnoDB)
and instead of failing, the test was skipped by run-time check in
have_innodb.inc.
