Problems with upgrade from 6.0.6 to 6.1.0

[ma bu, modifié il y a 12 années.]

Hi everybody,
at the moment I have some troubles with upgrade my portal from version 6.0.6 to 6.1.0.
The main problem is that I don't have a clue where the error comes from. But step by step:
I'm using a MySQL database with Liferay 6.0.6 running. Also I have a document library and
an image gallery.
I downloaded the new portal version, copied my portal-ext.properties and the document library /
image gallery folders to the new version and started everthing.
The upgrade process starts, but I get several errors while trying to upgrade the image gallery.

Just a NullPointerException... Any ideas?
Thanks in advance

I'd say the NPE is a bug; Liferay should not be throwing NPEs...

The core of the problem is that you have a missing image (an image is referenced in the database/doc lib somewhere that does not exist in your image library).

[Sergio González, modifié il y a 12 années.]

We changed the Hook in Liferay 6.1, so now Image Gallery uses DLHook for storing images. In order to have an automatic migration you may need to enable the following property (you need to set the Hook you were using in your previous Liferay version, before doing the upgrade, so Liferay will automatically migrate all those images to DLHook)

#
# In versions prior to 6.1, the Image Gallery portlet supported persisting
# images via com.liferay.portal.image.DatabaseHook,
# com.liferay.portal.image.DLHook, or
# com.liferay.portal.image.FileSystemHook. Since 6.1, only DLHook is
# supported.
#
# Set this property to the hook implementation to trigger automatic data
# migration during an upgrade.
#
#image.hook.impl=com.liferay.portal.image.DatabaseHook
#image.hook.impl=com.liferay.portal.image.DLHook
#image.hook.impl=com.liferay.portal.image.FileSystemHook

Thanks for your hints,
I tried to upgrade several times with the new image gallery property, (#image.hook.impl=com.liferay.portal.image.DLHook) but the error persists
Probably I should convert the image gallery in advance on 6.0.6, and after that do the upgrade?

Besides: what is the difference between the DLHook and the FileSystemHook? What will be converted during that data migration process?

Cheers

Thanks to all for the hints. Finally I found the problem in my database.
The problem was that in my database were some entries of images in the image gallery, but they were not on my filesystem.
So the upgrade process tried to migrate data which wasn't there. That's why the process finished with a NullPointerException.
