2015-02-06T23:09:43.443935Z 5 [ERROR] Invalid (old?) table or database name '@'
2015-02-07 10:09:43 0x7fe8bc004700  InnoDB: Assertion failure in thread 140637563275008 in file btr0cur.cc line 1239
InnoDB: Failing assertion: (fil_page_get_type(page) == 17855 || fil_page_get_type(page) == 17854)

How to repeat:
This assertion can be triggered with the testcase from bug 74876;

DELETE FROM mysql.innodb_table_stats WHERE table_name = 'test_ps_fetch_nonexistent';
create TABLE t1 (a int not null);
SET @start_global_value = @@global.auto_increment_offset;
CREATE TABLE mytable_ref (id int,constraint FOREIGN KEY (id) REFERENCES FOO(id) ON DELETE CASCADE) ENGINE=innodb;
SET @@global.innodb_trx_rseg_n_slots_debug = @start_global_value;
INSERT INTO t1  VALUES (INET6_ATON('')), (INET6_ATON('')), (INET6_ATON('::')), (INET6_ATON('::ffff:')), (INET6_ATON('::')), (INET6_ATON('::1')), (INET6_ATON('1020:3040:5060:7080:90A0:B0C0:D0E0:F010'));
SET GLOBAL innodb_file_per_table=0;
INSERT INTO t1 VALUES ('00:00:01.000012'); ;

However, you would have to run the testcase many times to trigger the bug (I think, not verfied) - usually it seems to trigger bug 74876 instead.

Adding a semi-testcase. Reducer script seems best at reproducing this.

In Percona Server the assertion is:

Failing assertion: (fil_page_get_type(page) == 17855 || fil_page_get_type(page) 

Here is what the assertion looks like in MySQL:

InnoDB: Failing assertion: index->id == btr_page_get_index_id(page)

Thank you for the report.

reducer_hacked_for_bug75913.sh  cannot start MYSQL server, because it cannot find privilege tables. Did I miss some option?

Also is it possible to specify custom WORKDIR_LOCATION?
[26 Feb 2015 23:19] Roel Van de Paar
Sveta, interesting, what does the startup log show exactly? Did you use something like make_binary_distribution and then use this? Reducer should put all that is needed in place.
[26 Feb 2015 23:20] Roel Van de Paar
And thank you for checking :)
[27 Feb 2015 18:01] Sveta Smirnova

hm... I use self-compiled distribution. Just cmake [option]; make; make install. Will try with binary package now.

Hi Sveta,

Thanks for trying. I tried again and used /tmp also to match your setup as closely as possible. It seems to reproduce easily (though have to check subreducers dirs - error in my earlier comment)

... more ...

I am not sure what the difference between our machines is. Let me see if I can make a better testcase next week. Should be possible.

I can verify getting the assertion one way, but I cannot accept the provided testcase as is.

pseudo-random testcase for the assertion I see.

Attachment: bug75913.cpp (text/plain), 6.66 KiB.

Posted by developer:
Fixed as of the upcoming 5.7.8, 5.8.0 release, and here's the changelog entry:

After a failed "DROP TABLE" operation, the purge background thread
asserted while attempting to access an index page of the table. Purge
should not attempt to clean a table that is marked as corrupt. Purge now
checks for a corrupt primary index. 

Thank you for the bug report.

there's still a problem in 5.7 with this. Filing a new bug shortly and putting in BPS.
