Hi,

I am trying to run the clone example from CDO 4.2-M2 using the bundles org.eclipse.emf.cdo.examples.master and org.eclipse.emf.cdo.examples.clone.

I changed the configuration of the master server as follows:
 <property name="overrideUUID" value=""/>
 <property name="supportingAudits" value="true"/>
 <property name="supportingBranches" value="true"/>
 <property name="supportingEcore" value="false"/>
 <property name="ensureReferentialIntegrity" value="false"/>
 <property name="allowInterruptRunningQueries" value="true"/>
 <property name="idGenerationLocation" value="CLIENT"/> 


Then I start the master server with an empty database and when starting the clone server with an empty database the clone throws an exception:
[WARN] Replication attempt failed. Retrying in 2 seconds...
org.eclipse.emf.cdo.common.util.TransportException: java.io.UTFDataFormatException: malformed input around byte 3

What am I doing wrong?

Another thing: I understood that the clone needs branching support, but does the master also need branching support and if yes, I would like to know why.

Thanks

//Jan

Normally this (or similar protocol problems) are caused by server and clients not using the exact same version/build.
I've recently implemented:

259086: Protocol versions should be checked
https://bugs.eclipse.org/bugs/show_bug.cgi?id=259086

But one of your peers may still be running an older version.

There's a minor potential for a string encoding defect. What charsets are you using?

Theoretically it wouldn't need branching if you actually don't use branches other than the main branch. But I doubt that
I added support for disabling branching explicitely. The consequence is that, for now, you get an extra integer column
in each attribute table.

Hi,

I checked the versions of both, they are started from within the same Eclipse instance and the versions look ok to me.

Do you mean the platform encoding? I guess it is CP1252, as I am running on Windows 7.

Do you mean by "support for disabling branches explicitly", setting "supportingBranches" to false in the master configuration is not supported for offline clones?

Cheers
/Jan

Let me play with an offline setup to see if we have a regression that's not covered by the tests...

Yes, that's what I mean. You can try, but I really think that it's not supported. It could be, though. As kind of an
optimization.

Hello,

I have an issue with the clone example as well.

If I start an empty .master server, and I start the .clone server, I get:

State changed from OFFLINE to SYNCING
[WARN] Replication attempt failed. Retrying in 2 seconds...
org.eclipse.net4j.db.DBException: org.h2.jdbc.JdbcSQLException: Table EOBJECT not found; SQL statement:

I have tried to install version 4.1, but with that, the master server doesn't start, throwing:

UPDATE:
I realize that I forgot to set idGenerationLocation to CLIENT. After setting it, I have the same issue as Jan.

I've already fixed the way the cdo-server.xml gets copied. Now
supportingEcore is set to false and the idGenerationLocation to

Thanks for the excellent news!

I'm looking forward to the running the new example. The screenshot looks very... tempting/teasing Smile

Best regards,
Cristian.

I am moving back here the discussion/ 2 posts related to this discussion:

Infinite loop on client: Open Session, Open Session, etc:
http://www.eclipse.org/forums/index.php/mv/msg/433382/978704/#msg_978704

Eike cannot reproduce the issue:
http://www.eclipse.org/forums/index.php/mv/msg/433382/979929/#msg_979929

After doing a little bit of debug, I realize that's the same issue as Jan's. But in my case I see that the trace is disabled so the exception is hidden:

Dear Eike,

What I discovered until now:

I see that the exception always happens after processing the DataInput that looks like this. I mean, this is processed ok, but the next invocation of ExtendedIOUtil.readString(DataInput) would throw the exception. The DataInput seems to be empty.

[h, t, t, p, :, /, /, w, w, w, ., e, c, l, i, p, s, e, ., o, r, g, /, e, m, f, /, C, D, O, /, E, r, e, s, o, u, r, c, e, /, 4, ., 0, ., 0,

Another thing, or question: I see that each time the client tries to reconnect:

...
Opened Session77 [repo1]
Opened Session78 [repo1]
...

it creates new threads:

...
Daemon Thread [Net4jReceiveSerializer-Channel[77, CLIENT, cdo]] (Suspended)
Daemon Thread [Net4jReceiveSerializer-Channel[78, CLIENT, cdo]] (Suspended)
...

but after the exception happens, the threads don't disappear, and they seem to enter in sleep, both client and server.

...
Daemon Thread [Net4jReceiveSerializer-Channel[77, SERVER, cdo]] (Running)
Daemon Thread [Net4jReceiveSerializer-Channel[78, SERVER, cdo]] (Running)
...

I think that the connection with the server is somehow not ended properly. If I'm not mistaking, this scenario, with a client failing in this way, could kill a production server, suffocating it with a lot of threads.

As this not happens on your setup, can you give me some hints regarding where I could put breakpoints and what should I look for?

Best regards,
Cristian.

Thanks for the infos. Can you please submit a bugzilla? I'm currently analyzing another strange effect with fail-over
replication. Thanks to the new example suite it's very easy now to play with the stuff and see issues we've not covered
in the tests. Of course this may take a while...

Cheers
