Description
I'm running MariaDB in Docker on Windows. Running the following script crashes the server:
drop table if exists t;
|
create table t (i int, j int);
|
insert into t values (1, 1), (2, 1), (3, 2), (4, 2);
|
|
|
select
|
i,
|
max(i) over (partition by (select 1))
|
from t
|
order by i asc;

Interesting, I couldn't reproduce it again when I re-created the schema. But then it happened again with this query:
select
|
i,
|
max(i) over (partition by 1),
|
max(i) over (partition by (select 1))
|
from t
|
order by i asc;
|
Attached my.cnf
and the result of "docker logs MARIADB & > log.txt" log.txt
... I'll be very happy to provide any additional info that you may need
Notice, I'm connecting to MariaDB using DBeaver, a JDBC based SQL client, in case this is relevant.
With the second query I am getting the crash, but stacktrace is different and it is the same as MDEV-15837 (fixed in 10.4.5)

ERROR 2013 (HY000): Lost connection to MySQL server during query

In the error log we see:

This could be because you hit a bug. It is also possible that this binary
|
or one of the libraries it was linked against is corrupt, improperly built,
|
or misconfigured. This error can also be caused by malfunctioning hardware.

We will try our best to scrape up some info that will hopefully help

diagnose the problem, but since we have already crashed,

something is definitely wrong and this may fail.

I can easily reproduce it for InnoDB table on Columnstore 1.2.5 using MariaDB 10.3.16. However, it doesn't break on vanilla MariaDB 10.3.16. Bummer.
This breaks:
select avg(comm_total) over (partition by customer) as wk_comm_avg, max(week(trade_date)) over (partition by year(trade_date)) as max_week from book_entry_cs;
|
this does not break:
(remove the partition from first or function from partition of second)
select avg(comm_total) over () as wk_comm_avg, max(week(trade_date)) over (partition by year(trade_date)) as max_week from book_entry_cs;
|
--or--
|
select avg(comm_total) over (partition by customer) as wk_comm_avg, max(week(trade_date)) over (partition by trade_date) as max_week from book_entry_cs;
|
In debug mode, it asserts the following in compare_order_elements():
DBUG_ASSERT(item1->type() == Item::FIELD_ITEM &&
item2->type() == Item::FIELD_ITEM);
In actuality, item2->type() == item::FUNC_ITEM
Not sure how this gets this way.
In sql_select.cc optimize_stage2(), Columnstore has added:
// @InfiniDB We don't need tmp table for vtable create phase. Plus
|
// to build tmp table may corrupt some field table_name & db_name (for some reason)
|
if (thd->infinidb_vtable.vtable_state == THD::INFINIDB_CREATE_VTABLE)
|
need_tmp = false;
|
Removing this allows the query to run against InnoDB correcty. Investigating other things.
As far as I can tell, this is a Columnstore build only problem. MCOL-3434 has been opened to track it.
