MySQL Bugs: #91362: Incorrect query results under certain conditions.

Bug #91362	Incorrect query results under certain conditions.
Submitted:	21 Jun 2018 15:18	Modified:	22 Jun 2018 4:45
Reporter:	Mark Schuart	Email Updates:
Status:	Verified	Impact on me:	None
Category:	MySQL Server: Optimizer	Severity:	S1 (Critical)
Version:	5.6.36 - 5.6.40 and 5.7.18 - 5.7.22, 5.6.40, 5.7.22	OS:	Any
Assigned to:		CPU Architecture:	Any

Description:
After a large number of DML statements, immediately followed by simple DQL statements, these DQLs sometimes return incorrect results.

If the DQL statements are repeated after a certain waiting time without further changes to the DB, the correct result is obtained.
This error can be reproduced in the following versions:
5.6.36 - 5.6.40 and
5.7.18 - 5.7.22

Earlier versions and the 5.5 branch do not seem to be affected.

Since I don't know the cause and it seems random depending on the system speed, I classify this bug as critical.

How to repeat:
Since the error only occurs after a sufficient number of statements, only the principle is described here.   

The genFiles.sh script creates a series of SQL test scripts.

If these are executed immediately one after the other against an existing database called "test", the following output or something similar can be obtained:

# mysql -D test < step1.sql; mysql -D test < step2a.sql; mysql -D test < step2b.sql; mysql -BND test < step3ff.sql;

However, the output is incorrect. The correct result is obtained after a short wait and executing the last SQL script again:

# mysql -BND test < step3ff.sql;

runSimple.sh and runSimple.bat are available for easy execution of these SQL scripts. They should work directly if no DB password is set for root.

What happens in detail (partly shortened):

step1.sql is used to prepare the database. It creates the necessary tables, inserts 9 lines in table "tf" and 2000 lines per line of table "tf" in table "tm". "tm.fid" refers to "tf.id" in later queries. "tm.ts" is always 1 and "tm.te" is always 999999990.

step2a.sql adds 2000 lines per line of table "tf" to table "tm" again.
Here, however, "tm.ts" and "tm.te" are set to 999999997 so that step3ff.sql can expect the same result at any time after execution of step1.sql.

In this simple example, only the number is determined.
All queries contained here should normally return 2000 as 2000 lines per line in "tf" are contained in table "tm".
So that the necessary conditions are fulfilled, attention was already paid to this in step1.sql.

Especially impressive is that even identical queries can lead to different results and that if the result is wrong it is always "1".
It is also noticeable that an odd-numbered query always returns the correct result and that even-numbered queries can produce wrong results.
