I fixed several syntax errors in the test suite, added second procedure but it does not crash

CREATE PROCEDURE SP2()

BEGIN

END;

$$

CREATE PROCEDURE SP1()

BEGIN

  DECLARE p INT;

  SET P = 2;

  WHILE ( p > 0 ) DO

    CALL SP2;

    SET P = P - 1;

  END WHILE;

END;

I need better test suite or I can try to fix bugs claimed to be duplicate (which can be only guess because there are triggers)

I don't use triggers anywhere in this database.

The crash always occure on the second call to the inner SP.

This error has been present at least since MariaDB 10.4.8, when I started to test version 10.4. It's currently preventing me from upgrading my Genealogy database from MariaDB 10.3, where this code works without any problems.
If there are changes to the SQL Syntax causing this, at least the whole database process (i.e. the Windows Service) shouldn't crash as it does now.

One more thing. When I first discovered this bug (probably when testing v 10.4.8 in the beginning of november 2019), I searched Jira and found a similar bug being filed and later marked as fixed.

I just noticed there actually is a third level of Stored Procedures being called from the Inner SP above (sp_bm_add_Note).
If required I could add this code to the ticket as well

In ideal world I need some instructions or SQL sequence to repeat the crash to fix it. So far I could not.

If required I could always upload my database. However, since it's about genealogy it contains information about now living people.
I will probably need a couple of days to make the testdata compliant with GDPR before I could upload it.

Usually to repeat the crash whole dataset is not needed.

We need schema of used tables (you can even rename fields if it is important, but in this case it shoud be checked) and tables filled with random junk. Of course there are cases when data distributin is important but statistically it is rare case and we can go step by step.

So if you have time send please SHOW CREATE TABLE output (or any other way to get the info) for used by Stored procedure tables (if some of them has foreign keys then connected tables also). If you have more time you can check that stored procedures at least pass syntaxically with the empty table created.

Even more helpful will be if you fill the tables with some test data and get crash.

But I will be happy if I get even minimum info above mentioned.

Oleksandr Byelkin added a comment - 2020-07-22 05:33 Usually to repeat the crash whole dataset is not needed. We need schema of used tables (you can even rename fields if it is important, but in this case it shoud be checked) and tables filled with random junk. Of course there are cases when data distributin is important but statistically it is rare case and we can go step by step.

I have now prepared a test database with GDPR compliant data.

Is there a way I can upload the database to you without making it available to the public at the same time?
The database is originally from a commercial genealogy product, with my own improvements added.

[EDIT]
I just found the information about uploading files to FTP. I will prepare an upload for you.

I have now uploaded the test database (with testdata) to FTP (private), file ~~MDEV-23094~~.zip .
You will also find some information and instructions in the Zip.

Kind regards

Is there anything more I can do to help?

Sorry but I had not time yet (I first have to finish the bugs I have started and then will be able to switch to this one). I hope our support will check it (ccalender ping).

I got the file, restored database.

Now I am trying to guess parameters of sp_bm_copy_EventToMany call to get the crash. If you know fow to get it fast, please say.

Please check the text file ('Information & Test instructions.txt") I included in the zip. It contains all information you need to know to do a full test.

Otherwise I will also add the same instructions below as in the text file:

CALL sp_bm_copy_EventToMany (2722, 'tree1', 'i9,i34', 1, '2020-07-24', 'USER');

The same call to the Stored Procedure can be executed several times.

bjomol if you need workaround, you can move condition with EXISTS/OR/NOT EXISTS (whall condition) out of IF.

i.e. make something like:

...

declare cond int;

set cond= ((EXISTS(SELECT...) AND EXISTS(SELECT...)) OR NOT EXISTS (SELECT ...));

IF (cond)

...

The problem is that SELECT_LEX of the subquery is not connected to main UNION, and so is not cleaned up properly...

~~MDEV-23094~~: Multiple calls to a Stored Procedure from another Stored Procedure crashes server

Added system-SELECT to IF/WHILE/REPET/FOR for correct subqueries connecting.

Added control of system/usual selects for correct error detection.

This script also crashes the server:

create or replace table t1 (id1 int primary key, data1 int);

create or replace table t2 (id2 int primary key, data2 int);

delimiter //

set sql_mode=ORACLE;

create or replace procedure p1(id int, dt int) as

begin

  while (1)

  loop

    exit when (exists(select * from t1 where id1 = id and data1 = dt) or

               not exists (select * from t2 where id2 = id and data2 = dt));

  end loop;

end;

//

delimiter ;

call p1(1,2);

call p1(1,2);

Review done. The patch is generally OK. A few comments made on slack.

Hello.

In the case of MariaDB 10.4.13 in Win64 (windows server 2019) environment on our test development server, MariaDB forcibly encountered a shutdown issue when executing multiple calling procedures.

You said there was no problem in version 10.3.
We also downgraded to version 10.3.24, but the same problem occurred.

Will there be a stable version 10.3?

Han Are you sure that you have this problem? You probably have to make bugreport of your problem.
