Description messiman 2005-10-24 22:23:23 UTC
1.) One PC with Windows XP embedded with IIS 5.1
2.) One PC with Linux (Knoppix 3.9, Kernel 2.6.11, XFree 4.3)
3.) I mount with the Linux PC to the Xp PC over dvfs 2.6 (mount -t davfs
http://192.1681.250/Documents /home/knoppix/Documents)

4.) The mount process works fine. I can create file change it, read and write it.
5.) Then I start OpenOffice (writer or calc) and create a new File with some
simple content.
6.) Then I save the file
7.) I check now the File on teh Windows Side. The file was created but it is empty.
8.) I can open it on the linux site and it is still empty.
9.) Now I save a new File with the ave or another content but now with a
different extension such as .doc or .pdf
10.) This works fine. The file is save on the windows directory.

It seems to me that all Open Documents Formats can't be saved over a mounted
wedav directory.

I have made also another test:
1.) Start OpenOffice and start writing a letter.
2.) Save it on teh Linux PC. This works fine.
3.) Copy the file to the mounted webdav directory.
4.) It can be open on the windows site without any problems.

For me it seems to be a problem in the saving mechanism in conjunction with davfs.

I will also report this problem to the guys of davfs.

I hope you can fix this problem.

Thank you.

Hi Juergen,

I will forward this issue to Kai, who is the expert on OOo's WebDAV Content

But before I do so, let me adjust the severity / priority (which you specified
as 'P1'). I do accept that this might be a severe issue for you, but the bug reporting guidelines
( should
provide some hints why this is probably not a 'P1' issue, but 'P2' at best.

Hi Kay,

can you please have a look at this issue?

We're not talking about OOo's WebDAV Provider here. From OOo's perspective the
DAV resource appears as 'normal' file system directory (this is what davfs is
for). Thus, the problem cannot be located in the WebDAV Provider, but in either
the File-UCP or the Package-UCP. Lets start with the File-UCP, which is with

Andreas, handing the issue over to yoy.

set to 2.0.3
Comment 4 andreas.bille 2006-05-02 08:59:45 UTC
abi->hro: Well, the problem is here, that we do not have the possibility to lock
the file for writing, which is, using the current design, mandatory for OO to
write files. We do have the same problem with linux systems having no lockdaemon
running. Some more general solution is needed .... like a new command -
"write-to-unlocked" or something like that.

KSO: Not enough time left to fix this for 2.0.3 Retargeting to 2.0.4
Comment 7 andreas.bille 2006-05-22 10:03:59 UTC
The problem is here the nonavailability of locking.
Comment 8 kai.sommerfeld 2006-08-14 14:29:25 UTC
KSO: No time to fix this in 2.0.4 timeframe. Setting target to 2.1.
Comment 9 andreas.bille 2006-10-16 16:26:55 UTC
Well - I was not able to reproduce the bug with my current linux system and an
OpenOffice 2.0.4.
But generally, OpenOffice tries to lock the file for writing and that might be
the problem - in the system wide configuration file of davfs there is the option
use_locks, which should be set to "1" to enable locks.

There are then also several questions with regard to zero length files on the
mailing list of davfs and I guess, you do have a problem with dav, otherwise.
OpenOffice handles the filesystem in a completly transparent way.
