[CDO] Howto remove a resource with Mars M7? [message #1695975] Wed, 20 May 2015 16:52 Go to next message

Hi,

With Luna, I could use the default "CDO Sessions" view to connect to a repository, open a session, open a transaction, select a resource, then do a right click and select "Remove" to delete the resource.

With Mars M7, I can still use the default "CDO Sessions" view to connect to a repository, open a session, open a transaction, select a resource, but then I just see a option "Delete" which is always disabled.

My repo configuration is very basic (no security manager).

Is there something special to do with Mars M7 to be able to delete a resource through the CDO default User Interface ?

Thanks,
Bernard.

Hi Bernard,

We now provide a CDO Repositories view and a Project Explorer integration for "checkouts" (which can also be online)
from the configured repos.

The CDO Sessions view is still supported and should work mostly like before. Due to the major UI refactorings it's
possible that there are some regressions, though. Please submit a bugzilla so that I can fix it. It would be great if
you could have a look for other functionality that got lost from the CDO Sessions view. Thanks!

Cheers
/Eike

Hi Eike,

See https://bugs.eclipse.org/bugs/show_bug.cgi?id=467754.

I also had the feeling that renaming a resource from the CDO view triggers a NPE, but I didn't check this deeply since we are using the CDO view only to delete resources (all the rest is done by code, and still works fine with Mars M7).

Best regards,
Bernard.

Hi Eike,

The problem is obviously still there with RC3 ...

BTW, I tried the new "Project Explorer integration".

On one side, it works and I can delete a resource in that way, on the other side it requires significantly more plugins, including net4j.db.h2 (?) etc ... which somehow annoys me because I need to embed only a minimal part of CDO-Ui in a RCP app.

Best regards,
Bernard.

Sorry, I didn't manage to fix this in time. But I plan to do a very early service release to address this and a few
other issues.

The inherent offline support of the new explorer requires a minimal CDO server and DB support. This could be factored
out of the explorer but that would take me a couple days and I doubt that someone would want to fund this work, given
that you'd only spare 4 or 5 smaller plugins. A cheaper work-around could be to mark the respective dependencies
optional/greedy and make the code more tolerant.

Ok, I will wait for the Service Release, it's such not a big deal.

Btw., I'm not sure that I fully understood the second part of your answer. I can clearly understand/admit that there are some dependencies to cdo core plugins, but why db.h2 ? CDO works also eg. with postgresql or other db-engines, and the chain explore.ui => explorer => db.h2 seems really a bit strange ...

It's already fixed now in both the master and the streams/4.4-maintenance Git branches. The maintenance builds will be
re-enabled after the 4.4 release is out next week.

The org.eclipse.emf.cdo.workspace plugin internally uses an H2 DBStore to provide SVN-like offline functionality
(CDOWorkspaces). That is used by the explorer plugin to provide offline checkouts.

That's also fixed now.
