I noticed something similar for application/xquery.
I have to admit that the WebDAV now behaves so smoothly now that I am
really using it! Thanks for that.
But, whenever I put some xq or xql it ends up being
application/octet-stream in the database. What I found interesting was
that it appeared to be logged as the correct mime-type. I tracked it
that far that in org.exist.webdav.ExistCollection the contentType that
is passed never gets replaced with the value of mime.getName() if that
is available. But mime.getName() is used for logging. I tried below 1
loc patch, which works for me, but I would be happy if someone could
confirm if this is right or not:

I experienced intermittent timeouts for certain webdav operations. Please share my laughter: the problem turned out to be jetty 7.1.5 jars that were still in the eXist-home/tools/jetty/lib/ directory. once I removed those, everything started acting smooth! Even sharing a davfs2 mounted eXist from samba to windows works fast and reliable. Possibly the old davfs2 1.2 needs the option "use_expect100 0". Thank you very much. -- peter |

Or is it still the DB managers responsibility to make these kinds of trade-offs between fast queries and fast deletion. There's ongoing work to decouple collections and resources in all indexes. In SVN trunk, this has been done for the main structural index, so there should be an improvement in update times. The range index will be next. Once we're done with this, the problem should be solved. Wolfgang |

All, A few minutes ago I committed a fix on the renewed webdav application. Two items to mention: Fixed: Spaces in names of collections and resources were %-encoded after storing in database. Attention: MiltonCollection implements LockNullResource now, with this LOCKing should work better. However I am not sure of this works yet, there was no code change required, so I am a bit suscpicious...

Ok... by browsing the mailarchives I understand that querying will be very fast on large collections but a delete operation is costly due to maintaining the indexes. Now I was just wondering if that plan from Wolfgang to automatically create some kind of equal-in-size subcollections to optimize performance has been implemented. Or is it still the DB managers responsibility to make these kinds of trade-offs between fast queries and fast deletion.

Can I point readers towards Microsoft's security model for NTFS and Active
Directory (which is in turn based on VAX/VMS)? It's simple in concept and
extremely flexible. The extended permissions models in modern UNIXes are
similar. There are:
- Objects that require securing;
- Rights that a principal may have over an object (these my be different for
each type of object);
- One access control list (ACL) for each object, containing a list of tuples
of <principal, right, allow/deny>.
I think what we're discussing here is what the rights should be, and whether
there are any that cannot / should not be taken out of the ACL. From my
experience, after writing such a permissions system for a virtual learning
system, I'd say that all combinations of things in the ACL should be
allowed.
Incidentally, the NTFS version of auditing is also extremely flexible and
worth a look. Finally, the designers have gone to considerable lengths to
ensure that an administrator cannot completely hide that they've taken some
underhand action, although they can hide what that action was.

nice bit of collab debugging on this issue,
I am very happy to see integration of milton here and I think it will
pay off nice dividends later on.

On request some more details on my configuration, could have included
that in my initial post, I know:
on ubuntu Karmic I mounted with
mount -t davfs http://localhost:8080/exist/webdav/db/ test/
which results in this mount:
http://localhost:8080/exist/webdav/db/ on /home/stefan/test.pr type
davfs (rw,nosuid,nodev,_netdev)
davfs2 version is 1.4.5-1
as davfs2 caches and delayes some writes I umounted between some tests
to see if there are some failures. In other cases I just waited some
time until I was positive that the bufferes must (should) have been flushed.
I tried to put a big xml-only repository there, which apparently works
alright. Therefore, in the mounted directory I did a:
svn export ~/prog/xmltexts/trunk/xmltexts xmltexts
a bigger rename operation worked as well:
for f in *.xml ; do mv -v $f "anon"$f; done
something more stressful, just to see what happens if we leave XML.
Apparently this works as well:
find -name "*.xml" -type f -exec shred \{} \;
cating and editing, updating the xmls (the real, not the shredded),
works as well.
Concerning my failed Nautilus tests (which I wouldn't follow any
further. I would suggest that whoever really wants to see webdav in
nautilus working should try to have it fixed it in nautilus, as that
would, I assume, be more efficient than adjusting every server
implementation towards nautilus' needs.)
Nautilus version: GNOME nautilus 2.30.1
with gvfs (all related packages, backends etc) version: 1.6.1-0ubuntu1
cheers and thanks,

Hello Adam, I am getting back to working on the WebDAV client module. I do like the idea of writing most of this in XQuery. It just makes sense. I do know that I will have to create a Java based function module to communicate with a socket, since the http-client.xqm makes calls to the httpclient Java based function module. I need to make calls to other HTTP methods. I am thinking that the simplest implementation would be: system:socket-comm-xml($uri as xs:anyURI, $port as xs:integer, $body as node()) as node()* Open a socket port for a given URI and then transmit the body and return the results. system:socket-comm-text($uri as xs:anyURI, $port as xs:integer, $body as $xs:string) as node()* Open a socket port for a given URI and then transmit the body and return the results. The socket-comm-xml will allow the creation of XQuery function modules to send any XML that someone might need to a socket on a server and retrieve the XML results back. I can then write the webdav-client.xqm that communicates with the subversion server to send the body of the HTTP PROPPATCH and appropriately interpret the results. What does our community think? Does anyone see any potential problems? If so, then do you have a suggestion on how to mitigate the problem? Loren On Aug 16, 2010, at 02:59 PM, Adam Retter wrote: > Do you need a new module?

I'm admin, but I don't have time to do all staff after all. So, it's more of

Hello Dannes, please excuse, if my silly plea did offend you. I second Stefans assessment of the state of eXist webdav support and linux clients. Thank you again for your efforts. May I report from the compatibility hunt a small problem persisting? It can also be seen in the windows webfolder client; on davfs2 this makes in-place editing very slow, in windows its more academic, I cannot tell about apple mac: A refresh (F5) of the webfolder following a PUT will timeout. The eXist logs last line then reads "DEBUG (PropFindHandler.java...". From looking at the tcp-stream with wireshark, the server response gets sent in a way, that probably both windows and davfs2 clients and also wireshark itself cannot decipher or is in itself incomplete. This with current trunk clean build. linux summa summarum - davfs2 1.4 is OK, except see above. options used: use_locks 0, delay_upload 0 - nautilus/gvfs is broken due to its own limitations, mounting dav:// instead of http:// prevents the not-found error, yet it still seems to be unable to cope without content-length. - davfs2 1.2 is broken too, that caused a false impression with me. -- peter |

Hi Dannes, thanks for your efforts building a working webdav implementation for eXist. As there appears to be some confusion around webdav on linux I did some very limited testing. As for davfs2, I can see no issues there. Synced numerous directories with binary and xml ressources to the server without any problems. I renamed files and modified file contents. I would consider this working. As for Nautilus, this appears to be a rather different thing. When using /exist/db/test for the directory it should mount it claims that it is not a WebDAV enabled share. When using /exist/db/test/ (note the slash) it requires authentication. This shows that it is at least partially working. But as soon as I present the correct credentials it claims that the ressource is not found. I guess (I think as peter previously pointed out) that this is because it tries to look at the parent directory(-y+ies) and gets a 404. The message the gui conveys is "Error: HTTP Error: Not Found". To be honest, I would not put endless effort into getting this working. As Nautilus is having similar issues with other WebDAV servers I would consider this a nautilus problem. I tried the same with apache's WebDAV module with similar results. cheers, Stefan |

Dmitriy is that the case? If so you explanation has made this much
more understandable for me, thanks :-)
Of course this is what CEO's want, but in my experience the admin can
always access absolutely anything if he or she wants to ;-)

Adam, I think Dmitriy is proposing a model where there is a clear separation
between being a member of a group and managing the group itself. I quite
like the idea and it takes care of a common case from the practice.
Example: An admin who manages the group of CEO users does not need to have
access to the confidential reports in a collection, available to the members
of this group.
When we discuss eXist security matters I think it is high time to start
looking at it from a slightly bigger perspective. Imagine a company of 1000
employees where to have one admin user that does it all is nor neither
possible nor practical . There will be teams of admins dealing with variety
of jobs across the teams and departments.

I'll continue to try to get things working under Linux, but things regarding WebDAV just seem to be not that mature in Linux it. That is a pity. This is an interesting page to read: http://milton.ettrema.com/compat/index.html ; it shows some basic requirements that need to be fulfilled to have WebDAV working for all platforms.
