This means that you’ve configured your xwiki.cfg file to use “void”:

#-# The attachment versioning storage. Use 'void' to disable attachment versioning. [Since 3.4M1] default is hibernate.
# xwiki.store.attachment.versioning.hint=hibernate

So this means you’ve disabled attachment versioning. However I don’t know why this is breaking something in your case.

Maybe @tmortagne has an idea?

Could you give us your config in xwiki.cfg for all xwiki.store.* properties?

Thx

Sure. Here are my uncommented store.* lines

xwiki.store.main.hint=hibernate
xwiki.store.attachment.hint=file
xwiki.store.versioning.hint=hibernate
xwiki.store.attachment.versioning.hint=void
xwiki.store.attachment.recyclebin.content.hint=file
xwiki.store.migration.manager.hint=file
xwiki.store.recyclebin.content.hint=hibernate
xwiki.store.attachment.versioning=0

I think you should raise a jira issue for this on jira.xwiki.org and explain clearly how to reproduce. Thanks

5

The error you pasted is not related to versioning. According to it you have “void” which is set for xwiki.store.attachment.hint.

6

Nope, xwiki.store.attachment.hint=file
Do I understand correctly than xwiki read this parameter from /etc/xwiki/xwiki.cfg (ubuntu) and it is not overwritten anywhere else?

7

Yes xwiki.cfg is the only place where this can be set, maybe you have it set several times ?

8

No, that option set only once.
BTW, I have an interest warning on xwiki startup

[XWiki initialization] WARN onfiguredQueryExecutorProvider - Could not find a QueryExecutor with hint [hibernate] which is the hint for the storage engine, defined in your XWiki configuration under the [xwiki.store.main.hint] property. The default QueryExecutor will be used instead. Reason: [ComponentLookupException: Can’t find descriptor for the component with type [interface org.xwiki.query.QueryExecutor] and hint [hibernate]].

When I comment xwiki.store.main.hint=hibernate in xwiki.cnf that warning dissapers.

Finally reproduced and debugged this, it’s actually a bug related to the handling of xwiki.store.attachment.versioning=0. See Loading....
