No visible effect on non-debug builds. However a more complicated and dirtier test case having the same elements (triggers, views, SPs) causes a failure on a non-debug build too (while the same assertion failure on a debug build):

serg, please review fix for this bug. I cherry-picked one from MySQL.

Unfortunately I don't feel very comfortable with this code and thus my analysis should be considered weak.

The sql_view.cc change doesn't seem to be required, looks like it is just an optimisation to avoid table_list extension in first place. At the same time it fixes CREATE VIEW problem.

The sp_head.cc change fixes both problems.

Comment by Sergey Vojtovich [ 2018-10-17 ]

The patch is committed as [Commits] 2be83a2: BUG#19988193: ASSERTION `(*TABLES)->REGINFO.LOCK_TYPE >= TL_READ

Comment by Sergei Golubchik [ 2018-10-19 ]

I think it'd prefer this one-liner instead:

diff --git a/sql/sp_head.cc b/sql/sp_head.cc
 
--- a/sql/sp_head.cc
 
+++ b/sql/sp_head.cc
 
@@ -4105,7 +4105,7 @@ sp_head::merge_table_list(THD *thd, TABLE_LIST *table, LEX *lex_for_tmp_check)
 
   }
 
 
   for (; table ; table= table->next_global)
 
-    if (!table->derived && !table->schema_table)
 
+    if (!table->derived && !table->schema_table && table->lock_type != TL_IGNORE)
 
     {
 
       /*
 
         Structure of key for the multi-set is "db\0table\0alias\0".

This prevents TL_IGNORE tables from being added to the SP's m_sptabs hash. MySQL's patch adds them and then skips when copying it to the prelocking TABLE_LIST. As far as I can see, the purpose of m_sptabs is to list tables that needs to be prelocked, so it's seems strange to add tables there that will be ignored during prelocking.

Comment by Sergey Vojtovich [ 2018-10-19 ]

serg, I updated patch as you suggested and it seem to work. However I couldn't come up with a good comment. Specifically I wonder why do we go that far and try locking TL_IGNORE? Why is_not_allowed_in_function() didn't filter such statements out?

I can look into that myself, but it means this fix has to be postponed for the next maintenance sprint.

Comment by Sergei Golubchik [ 2020-02-14 ]

Because is_not_allowed_in_function() happens later. First all tables are opened, then is_not_allowed_in_function() throws an error — this is exactly what happens if the fix as above is applied.

Comment by Roel Van de Paar [ 2021-01-18 ] 

CREATE TABLE t (a INT);
 
CREATE PROCEDURE p() RENAME TABLE t TO t2;
 
CREATE TRIGGER tt AFTER INSERT ON t FOR EACH ROW CALL p();
 
INSERT INTO t VALUES (0);
