MVCC: RuntimeException: Unexpected code path in simple SELECT #150

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
(simple SQL scripts or simple standalone applications are preferred)

Happens sometimes with our production database. Only if MVCC=TRUE. Alas, I
yet don't know how to reproduce it with a small test database (still
investigating). We cannot give our production db to you, sorry. It is not
even possible to extract portions of it, because there are many entangled
tables involved.

What is the expected output? What do you see instead?

our *.trace.db file contains the following exception:

/**/PreparedStatement prep308 = conn2.prepareStatement("select

[more stack trace from JSF EL evaluation omitted]

What version of the product are you using? On what operating system, file
system, and virtual machine?

H2 1.1.118
Windows XP SP 3
NTFS
Sun JRE 1.6.0-16

Do you know a workaround?

No.

How important/urgent is the problem for you?

Very urgent.

In your view, is this a defect or a feature request?

Defect.

Please provide any additional information below.

H2 is running embedded (jdbc:h2:file:<path>/db;MVCC=TRUE). Using Hibernate
3.2.2 with C3P0 connection pool, keeping 3 connections open all the time.

Original issue reported on code.google.com by dmoeb...@gmx.net on 15 Dec 2009 at 4:07

GoogleCodeExporter commented 9 years ago 
Could you check in the .trace.db file if there remaining stack trace is there 
and add
it here? The [more stack trace from JSF EL evaluation omitted] is very 
unfortunate.

I think it's a bug, but without reproducible test case it will be 
very hard for me to reproduce and fix it I'm afraid. Could you send
me the result of:

SELECT * FROM INFORMATION_SCHEMA.SETTINGS 

If you can reproduce it, could you try if it's also reproducible
using version 1.2.125 (using the page store)? I know version 1.2
is still beta, but it would help narrow down the root cause.

Here's the result of "SELECT * FROM INFORMATION_SCHEMA.SETTINGS".

I managed to reproduce this exception with 1.2.125 once (with page store), and 
the
stack trace was exactly the same. However, I'm not able to reproduce this issue
permanently with either version.

Thanks... Everything looks normal. What database URL do you use?

Could you please append ;TRACE_LEVEL_FILE=3 to the database URL, 
run your application (until you get the problem) and then send 
me the .trace.db file?

It's possible that this is a follow-up error of issue 158. We tried to delete a
master record that had children attached to it without cascading delete. After 
that
the MVCC index was probably corrupt. A query on the child records (using the 
foreign
key index) didn't retrieve all results. Could it be that because of this 
situation we
ran into line org.h2.index.MultiVersionCursor.next(MultiVersionCursor.java:144) 
?

PS: the database URL is: jdbc:h2:file:C:/dev/temp/h2-matrix-db/matrix;MVCC=TRUE

As far as I understand, this is a duplicate of issue 158. Please tell me if I'm 
wrong.

I'm afraid I will not be able to fix it with version 1.1.x (page store 
disabled). I
think it doesn't make sense to keep the issue open because it works with the 
current
release (page store enabled).
