ownCloud @ Chemnitzer Linuxtage 2014

March 19, 2014 6 comments

Last weekend Daniel, Arthur, Morris and me were in Chemnitz where the Chemnitzer Linuxtage 2014 took place. We drove a booth during the two days, the CLT host around 60 boothes of companies and FOSS projects. I like to go to the CLT because it is perfectly organized with great enthusiasm of everybody involved from the organisation team. Food, schedules, the venue, everything is perfect.

Even on saturday morning, short after opening of the event, somebody from the orga team was showing up on the booth with chocolate for the volunteers, saying hello and asking if everything is in place for a successful weekend. A small detail, which shows how much effort is put into organization of the event.

As a result, visitors come to visit the event. It’s mostly a community centric event: Exhibitors are mostly representing FOSS projects such as openstreetmap.org, distributions like Fedora or openSUSE or companies from the free software market.

The majority of visitors are mostly interested in private use of the software. But, no rule without exception, we also had a remarkable number of people from companies, either executives or people working in the IT departments, who were interested in ownCloud.

Speaking about ownCloud, I want to say that it’s amazing to represent our project. People know it, people like it, people use it. In private, but also in professional space people work with ownCloud already or are planing to start with ownCloud. ownCloud already is the accepted solution for the problems that became so practical with the NSA scandal last year.

My talk with title A private Cloud with ownCloud on Saturday morning was very well received and went smooth. The room was too small, lots of people had to stand or sit on the stairs. It was a very positive atmosphere.

Something that changed compared to last year and the year before: Most discussions were around how ownCloud can be installed, integrated and used and not any more about which features are still missing or maybe also bugs.

So it were two very exhausting days, but big fun! Thanks to Daniel, Arthur and Morris for the work and fun we had on the booth, and thanks to the CLT team for CLT.

openSUSE to Develop

December 6, 2013 Leave a comment

Have you ever wondered why openSUSE is the platform for development? Because it offers all that is needed for professional development, also if development goes beyond the basics.

A nice proof that openSUSE has more than others was posted here by our friend Thomas, a convinced Debian user. He writes about setting up openSUSE in vagrant to be easily able to build (master build) the ownCloud Client for Win32 in it. Very easy and cool stuff. But that can be even easier without vagrant through this link ;-).

Btw, there is an appliance in SUSE Studio to ease experiments with vagrant with openSUSE as base. I haven’t tested yet, experiences?

openSUSE on RaspberryPi with ownCloud

November 19, 2013 9 comments

This morning during a cup of coffee I wanted to do something adventurous. I put the raspberry which I bought recently (without having very much played with it because of my light apt-* allergy) on the table and thought I will try to install the openSUSE distribution.

I remembered awesome Bernhard was blogging about that topic recently. On that page one can find this link where raspberrypi images can be found. Oh, surprise, there is even a file from november 10th, so I downloaded that. People always recommend the latest stuff.

Following this Howto I quickly had the RaspberryPi running in my home network, surprisingly enough identifying itself as powered by openSUSE 13.1 :-)

Well, that was easy and far away from adventure which I was looking for. So I remembered that the cool kids on the block have an ownCloud server running on the RaspberryPi. Would that be as easy? There are no official packages for the Pi yet, so what could I do?

Well, ownCloud is noarch, because it is plain PHP. So I downloaded the two ownCloud server packages owncloud and owncloud-3rdparty from our ownCloud nightly build repository on OBS and installed them with

zypper in owncloud owncloud-3rdparty

I was (adventure!) ignoring all the warnings and stuff, what you should never do! Just for a test, before the coffee is cold.

After having started apache, what should I say? It simply worked. No need for antihistamine, all nice green around, and ownCloud running after having finished it’s setup page.

That really pushed me for the day! It was such a smart experience having that running within a couple of minutes, with absolutely no fiddling around. This is cool stuff! Thanks to Bernhard and all the other openSUSE guys for doing that!

My congrats for the 13.1 release! I really hope that people will understand (again) how awesome the openSUSE distribution and the project is, especially for the more nerdy folks! Really, you wanna run the Geeko these days.

Enough praise, now, maybe there is somebody who will help me in OBS to provide proper ownCloud packages for ARM? I am sure there is not much missing.

And if you want to run ownCloud on your “normal” PC, this is the repository of the latest stable version which we actively maintain…

Kraft Release 0.53

October 12, 2013 Leave a comment

Only short time after Kraft’s release 0.51 I am announcing version 0.53 today. Kraft is the KDE software that helps you to handle your daily quotes and invoices in your small business.

The new release fixes a problem with the tarball of 0.51 which contained a wrong source revision. That did not cause any harm, but also did not bring the announced fixes. That was brought up by community friends, thanks for that.

Additionally another, actually the last known bug of Kraft’s catalog management was fixed. That was the problem that it did not work to drag sub chapters onto the top level of the catalog. That is working now.

Please update to the new version and help us with your feedback.

DAV Torture

September 27, 2013 9 comments

Currently we speak a lot about performance of the ownCloud WebDAV server. Speaking with a computer programmer about performance is like speaking with a doctor about pain. It needs to be qualified, the pain, and also the performance concerns.

To do a step into that direction, here is a little script collection for you to play with if you like: the DAV torture collection. We started it quite some time ago but never really introduced it. It is still very rough.

What it does

The first idea is that we need a reproducable set of files to test the server with. We don’t want to send around huge tarballs with files, so Danimo invented two perl scripts called torture_gen_layout.pl and torture_create_files.pl. With torture_gen_layout.pl one can create a file that contains the layout of the test file tree, a so called layout( or .lay)-file. The .lay-file describes the test file tree completely, with names, structure and size.

torture_gen_layout.pl takes the .lay-file and really creates the file tree on a machine. The cool thing about is that we can commit on a .lay-file as our standard test tree and just pass a file around with a couple of kbytes size that describes
the tree.

Now that there is a standard file tree to test with, I wrote a little script called dav_torture.pl. It copies the whole tree described by a .lay file and created on the local file system to an ownCloud WebDAV server using PUT requests. Along with that, it produces performance relevant output.

Try it

Download the tarball and unpack it, or clone it from github.

After having installed a couple of perl deps (probably only modules Data::Random::WordList, HTTP::DAV, HTTP::Request::Common are not in perl’s core) you should be able to run the scripts from within the directory.

First, you need to create a config file. For that, copy t1.cfg.in to t1.cfg (don’t ask about the name) and edit it. For this example, we only need user, passwd and url to access ownCloud. Be careful with the syntax, it gets sourced into a perl script.

Now, create the local reference tree with a .lay-file which I put into the tarball:

./torture_create_files.pl small.lay tree

This command will build the file tree described by small.lay into the directory called tree.

Now, you can already treat your server: Call

./dav_torture.pl small.lay tree

This will perform PUT commands to the WebDAV server and output some useful information.
It also appends to two files results.dat and puts.tsv. results.dat just logs the results of subseqent call. The tsv file is the data file for the html file index.html in the same directory. That opened in a browser gives a curve over the average transmission rate of all subsequent runs of dav_torture.pl (You have run dav_torture.pl a couple of times to make that visible). The dav_torture.pl script can now be hooked into our Jenkins CI and performed after every server checkin. The resulting curve must never raise :-)

To create your own .lay-file, open torture_gen_layout.pl and play with the variables on top of the script. Simply call the script and redirect into a file to create a .lay-file.

All this is pretty experimental, but I thought it will help us to get to a more objective discussion about performance. I wanted to open this up in a pretty early stage because I am hoping that this might be interesting for somebody of you: Treat your own server, create interesting .lay files or improve the script set (testing plain PUTs is rather boring) or the result html presentation.

What do you think?

ownCloud Client Release 1.4.1

September 26, 2013 6 comments

I am happy to announce that we today were able to release version 1.4.1 of the ownCloud Desktop Client on the three platforms Linux, MacOS and Windows.

You find suitable download links as usual at:

Version 1.4.1 is a bugfix release for the 1.4.0 version released a few of weeks ago which brought a lot of new features. This one solves a couple of problems that were coming up during the last few weeks. For example, the problem that the client lost its configuration (at least) on the Win32 platform when the machine was shut down is fixed. Also a lot of redundant uploads wont happen any more. And there are even more fixes, as the detailed Changelog rules out.

We thank you for your ongoing support and the good work on bugs that came up. As usual we are looking forward to your feedback. Please work with us in the Github bugtracker if you experience issues.
