 Description   

I created an OQGraph table and pointed it to an existing MyISAM table that already contains data. Upon querying the OQGraph table I see

MariaDB [MidSchipDB_unstable]> SELECT * FROM version_history;
 
ERROR 1017 (HY000): Can't find file: './MidSchipDB_unstable/db_history@=Cܹ' (errno: 2 "No such file or directory")

My setup is:

The culprit is the combination of length of the schema name and the table name. So, to reproduce the bug with the provided create table statements, it is important that you have a schema with the same name MidSchipDB_unstable, or a different name of the same length.

Comment by Andrew McDonnell [ 2014-04-07 ]

I can actually repeat this. I am having a bit of trouble narrowing on the exact combinations that cause - possibly heisenbug related, but I expect to get the exact test case eventually

Comment by Elena Stepanova [ 2014-04-07 ]

The very same test case that was provided in the description worked for me, just add

create database MidSchipDB_unstable;
 
use MidSchipDB_unstable;

before selecting and querying the table.
I also replaced the names with something like d0123... t0123... , it happens all the same as long as the combination of lengths is preserved.

Comment by Andrew McDonnell [ 2014-04-07 ]

or not - combinations which fail sometimes pass if things done in a different order. I smell a memory overrun of some kind. In particular because sometimes the fails show junk at the end of the table name in the error message.

There is a fragment of code in ha_oqgraph::open() which I never really grokked why it was done the way it is, I suspect the cause is in there, and will investigate that further.

Comment by Andrew McDonnell [ 2014-04-07 ]

Yes, using the exact example was the first thing I repeated. Where the sands were shifting was when I added and removed characters and the order I created different combinations. At on point i got it to fail with a database called `1` and a table called `4444`...

I thought I used to be able to run mtr with valgrind, but not the tets exits, it seems o have a timeout waiting for mysqld or something

Comment by Elena Stepanova [ 2014-04-07 ]

You should still be able to run with valgrind, but it should be a fairly new valgrind. With the old one, it fails due to an unknown option (I don't remember the exact symptoms, it could look like a timeout on startup – but in any case, it should appear in the error logs)

Comment by Elena Stepanova [ 2014-04-07 ]

Here is what I'm getting with valgrind (just dumping the whole thing):

thanks, that pretty much nails it wround where I thought it would be

Once case it fails when the length of the backing store name > length of oqgraph table name
Although on reflection looking more like a zero terminated problem.

I don't think so. I use the same table names in a different database (with a slightly shorter database name) and there it works fine.

I have pushed the fix for this in my branch https://code.launchpad.net/~andymc73/maria/oqgraph-maintenance , commit 3974

Comment by Andrew McDonnell [ 2014-04-07 ]

Was lack of C explicit zero termination randomly causing a fail

This was merged in 10.0.11 and tests currently pass, so I hope I can take the liberty of resolving it...
