ownCloud log (data/owncloud.log)

Nothing is logged

I did a few tests and could detect some strange things.
I test to mount davfs from demo.ownloud.org and it works. But demo uses version 10.0.3.3 (a version on wich it was working for me before the upgrade).
Cadaver is working on my 10.0.4.4 owncloud but not davfs.
I did some tests using curl and can see that a simple curl to remote/webdav without autentication retunr a code 200 instead of a code 401

It appears that davfs make a first OPTIONS call without authentication, waits for a 401 and then proceed to authentication.
Here are my davfs logs:

Shouldn't something which worked before and stopped to work after an update be reported to a bugtracker rather then user forums?

[matan]

Same issue with my docker setup. I've upgraded to 10.0.4 from 10.0.3 and now WebDav isn't working. Has this issue been reported on github yet?

[hodyroff]

Issue: Owncloud 10.0.4.4 DavFS issue

Workaround does already exist and works. Patch is worked on and will then be in 10.0.5.

[thommie]

Hi,
does someone know if this severe issue was fixed in 10.0.5? I can not find it in the changelog.

[guruz]

FYI, if you don’t want to do a WebDAV mount, you can also use the ownCloud desktop client’s VFS mode which downloads files on double click (other files are just “placeholders”).
