I would like to suggest you also an svn based storage if that is conceivable or at least
to leave the space for hooks so that a post-commit xwiki "reload-from-directory"
and a "post-xwiki-save-commit" are hookable to synchronize with whatever you
wish.
Well git would be better (better binary compression) but in either case it
would be either bringing
in a large library or depending on an external (non java) application. I'm not too
interested in any
more .war bloat and I'm pretty sure depending on native code is out of the question.
I wonder if you don't want, right away, a virtual-file-system so that such as an
ftp-mount (for some spaces?) is doable.
There is no reason why anything which could be mounted could not be used. So nfs, nbd,
samba would
definitely work. I'm not familiar with an ftp mount but if it provides a regular
filesystem, it
should make no difference.

I would like to propose a different method for
attachment storage. I have spent some time working on
referencing using a UUID and have run into problems with how to garbage collect files if
the
corresponding database entry should go missing as well as problems with getting UUID
standardization
approved.
I would like to try a different direction.
There will be a directory for the wiki, one for the space and one for the document.
Inside of the
document directory will be the attachments.
An attachment called myImage.png attached to the document xwiki:Main.WebHome will be
placed in the
following location:
<filesystem store directory>/xwiki/Main/WebHome/attachments/myImage.png
If there is an XWikiAttachment entry in the database, the metadata from that entry will
be matched
with the attachment.
If there is no metadata entry but there is a file, empty metadata will be created.
Users will have the option of adding attachments to documents by copying the files into
the relevant
directory.
An escaping scheme will have to be adopted to prevent attachments named
../../../../../etc/passwd or
the like.
I have not started on this, I would like to see some +1 before I start writing code.
WDYT?
Caleb
