Hi devs,
We have a unintended regression in the standard import: if what you
import is identical to what is already in the database (including the
author) it won't add a new version (if you use the default option "Add
a new version to the existing page").
What happen in practice is that if you keep calling XWikiDocument#set*
methods with the same data it won't update the metadata or content
dirty flags. This flags are what hibernate store look at to know if it
should add a new version or not.
You can reproduce the same behavior with a simple script which load a
document, always set the same content and save. You will notice that
the history of that document does not change.
So the question is do we force metadata dirty to true all the time in
the instance output filter or do we keep this feature (in which case
we should optimize it a bit to not do the useless XWiki#saveDocument
but that's another subject).
WDYT ?
It could be seen as a nice feature but in practice my first reaction
was WTF and you often want to be sure the import actually did
something so I'm +1 to force metadata dirty. But I'm +0 to keep the
current behavior if there is a majority for it.
It’s hard to decide...
Same as you, I also thought it was a nice feature when I learnt that this was what was
happening :)
Actually something I’ve always wanted was to avoid generating new revisions when users
edit a page and click save without changing any content instead of clicking cancel (a lot
of users do this, generating unnecessary revisions and when you’re the owner of a wiki,
it’s a pain to check the diffs to find out that there was no changes). But this could be a
feature implemented at the level of the editor save button I guess. It’s a bit different
since the author would be different but we wouldn’t want a save in this case.
So I’m +0 for both behaviours with a slight preference toward forcing a rev to be
created.
Thanks
