I also arrives to XWiki from MediaWiki years ago. So, with the current
MediaWiki release, is it possible to do section edition and get a
warning only if two users edit the same section?
Thanks!
To be sure, I did some tests here:
http://www.mediawiki.org/wiki/Sandbox
no warnings, you can even edit the same section but then you'll need to get through
the merge phase. In that
case you see such a message:
Someone else has changed this page since you started editing it. The upper text area
contains the page text
as it currently exists. Your changes are shown in the lower text area. You will have to
merge your changes
into the existing text.
Well, I don't see this blocking behaviour working with MediaWiki
sandbox... I don't know why! In any case, MediaWiki is not the case here!
Just summing up:
Thanks for that summary, let me comment on your thoughts:
1. Simultaneous edition is possible, but not
advisable with the current
XWiki release.
Yes, especially that there is no merge phase after concurrent editing ( or maybe there is
a 'merge plugin' -
I'd be grateful for any info on that ). In that case you end up with the article
content overridden by
someone else and your only hope is to dig in the document's history and try to fix
edits manually.
2. Locking is done at document level.
Is that going to change in the future ? In my opinion that basically blocks user
groups/communities from
working on the documents in a collaborative way. Is it much work to make that lock
'section sensitive',
architecture-wise ? If someone could describe what should be done / changed in order to
achieve that, maybe
we could figure out a solution for that issue.
3. A true real-time edition editor for XWiki is
on its way and will
solve all these issues!
Well, it could be, but it's based on the js/ajax - it could be tricky to achieve a
good level of
compatibility between browsers ( of course it could be done, Google docs is a good
example here ). Of course
I'd take that right away in the stable form. But I think merging/lock on the section
level could be more
than enough for the ordinary wiki users ( Wikipedia is basing on that model on a huge
scale and it's doing
fine ;) )
It will be great if some developer or more
skilled user could review
this statements to confirm/deny/complete them! Thanks!
I concur. Currently I'm struggling to figure out how to get over that problem. I can
tell my users just to
ignore the lock message, but that is not super safe and could cause a content
loss/corruption.
Looking forward to your feedback guys !
I do agree with you, Piotr. In fact, when I present XWiki to a new group
of users, this is the question I would like to avoid: how XWiki manage
concurrent edition?
I talk about locking behaviour and a future real-time editor, but this
is not a good answer at all. To use instant messaging to agree on a
timetable to edit a document is what we currently do here. But it is a
solution out of XWiki (even though it is not costly at all as we use
instant messaging extensively in our research groups) and I don't like
to propose this kind of workarounds as I'm trying to show how to use
XWiki to collaborative writing among other uses.
I'm a bit surprised of being discussing this issue here as we are
already in a 2.7.z release of XWiki. Perhaps I'm missing something, but
I am not able to find an answer either.
Thanks for your thoughts!
Regards,
Piotr
