DB4O and HostKind.LOCAL do not work #30

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
Reported by Dave LeBlanc:
Hi all, this is a weird error - when setting up guice to use DB4O in
LOCAL mode (to have warp-persist create it's own db4o server and have
the @Transactionals connect as clients to it) as follows, I get a long
and confusing error message.

Set up in code as:

       bindConstant().annotatedWith(Names.named(Db4Objects.PORT)).to
("1234");
       bindConstant().annotatedWith(Names.named(Db4Objects.HOST)).to
("localhost");
       bindConstant().annotatedWith(Names.named(Db4Objects.USER)).to
("db4ouser");
       bindConstant().annotatedWith(Names.named
(Db4Objects.PASSWORD)).to("secret");
       bindConstant().annotatedWith(Db4Objects.class).to
("bigGame.db");

This is with version warp-persist-2.0-20090214 (my prior bug message
was using this same version too).

This gives this error message when I attempt to do a query:

r306 has a unit test for this issue, but I'm not able to reproduce it.
Not using the 20090214 distribution, and not with the current trunk. Could you 
check
the unit test and maybe submit one that does fail with your setup?

One thing I noticed was that you're not binding a Configuration object, which is
required in local mode. This should give you a different error though.

Another thing you can look at is quartz, it seems like you're using quartz 
somehow,
which could mean you're running background tasks. Mixing background threads 
with Warp
Persist is risky, becuase it uses ThreadLocal storage.

Shouldn't cause any issues if using WorkManager (which was specifically 
designed for
this purpose).

I'll code up a unit test and see if I can recreate this issue.

I'll ask separately about transactions and quartz on the mailing list.

Quick note: 

Using warp persist 1.0.1 and DB4O 6.4, it doesn't display this error.  This 
shows up
with warp-persist-2.0-20090214 and DB4O 7.8 and Mid-Feb SVN version. I'll take 
a look
at isolating out those newer versions to see if I can narrow down when it 
appeared
(which is a little more difficult since newer DB4O's require a newer 
warp-persist).

We use DB4O 6.4.14.8131 for testing.

David, is there anything you found out and can share with us? This is one of the
issues holding back the 2.0 release so I would like to resolve it as soon as we 
can.

GoogleCodeExporter commented 9 years ago 
Still seeing it with SVN rev 307 and db40 7.8.80.12541, using 6.4.14.8131 has 
fixed the issue. I've also found 
that recent 7.x's contain serious memory leaks in the native query side, so I 
don't think I'd use that anyway.

This problem isn't as bad as it was because I can now wire in a Configuration 
where I couldn't before.

Thanks,

 -Dave
