This is an updated version of the post from July 2015: https://www.pokorra.de/2015/07/submitting-patches-to-kolab-via-phabricator/

For a description of phabricator, see the post from July 2015.

Here are the updated instructions for using arcanist with CentOS7:

yum install git vim php-cli python-pep8
# this does not work because of contradicting dependancies:
# wget https://obs.kolabsys.com/repositories/Tools/CentOS_7/Tools.repo -O /etc/yum.repos.d/kolab-tools.repo
# yum install arcanist
git clone https://github.com/phacility/libphutil.git
git clone https://github.com/phacility/arcanist.git
export PATH=$PATH:/root/arcanist/bin/
arc set-config default https://git.kolab.org
arc install-certificate 
# go to https://git.kolab.org/conduit/login/ and copy the token and paste it to arc

Now get the repository you want to work with, eg. pykolab:

export PATH=$PATH:/root/arcanist/bin/
git clone https://git.kolab.org/diffusion/P/pykolab.git
cd pykolab
# do your changes
# vi pykolab/auth/ldap/__init__.py
git commit -a
arc diff            # Creates a new revision out of ALL unpushed commits on
                    # this branch.

Now you have a new Differential revision, in my example at: https://git.kolab.org/D559

Today, one of our customers at TBits.net noticed that when composing an e-mail in Roundcube, there is a spell checker button at the top. But only for English, and when there was text in the e-mail, and he clicked on the spell check button, he got the message: “An error was encountered on the server. Please try again later.”

I found the cause in the Roundcube log file, in /var/log/roundcubemail/errors:

PHP Error: Spell check engine error: Pspell extension not available in /usr/share/roundcubemail/program/steps/utils/spell.inc on line 50

So I installed the required packages:

yum install php-pspell aspell-de
systemctl restart httpd

Now this works for English. It seems for German and other languages, there are no packages readily available in the repositories.
I checked https://apps.fedoraproject.org/packages/aspell-de, there are packages for Fedora, but not for EPEL.

So you go to https://ftp.gnu.org/gnu/aspell/dict/0index.html#0.60 and download the dictionary for your language, and install it like this on your Kolab server:

tar xjf aspell6-de-20030222-1.tar.bz2
cd aspell6-de-20030222-1
./configure
make
make install

Now do a reload in Roundcube, and now you can check your spelling even in German!

 

Update: It was suggested by Luca Berra from Italy, to use enchant and hunspell instead of pspell/aspell.

For a discussion of hunspell vs aspell, see http://penguindreams.org/blog/aspell-and-hunspell-a-tale-of-two-spell-checkers/

Luca gave me these instructions:

yum install php-enchant hunspell-it
 
vi /etc/roundcubemail/config.inc.php
    $config['spellcheck_engine'] = 'enchant';

I have not tested this. Thanks to Luca for this suggestion!

Please note: I am only using public information. I have no background knowledge about the releases.

Today, the roundcubemail package has been updated from version 1.3.0.41 to 1.3.3. This fixes a security issue, described in https://roundcube.net/news/2017/11/08/security-updates-1.3.3-1.2.7-and-1.1.10. Also see the release notes https://roundcube.net/news/2017/09/04/update-1.3.1-released and https://roundcube.net/news/2017/10/31/update-1.3.2-released for new changes.
Because of this, the packages iRony, kolab-freebusy and kolab-syncroton have been rebuilt as well.

In the past days, erlang-eimap has been updated with a patch for untagged commands. Because of that, guam has also been rebuilt. For details see https://obs.kolabsys.com/package/rdiff/Kolab:16/erlang-eimap?linkrev=base&rev=8

Ansible with su instead of sudo   October 13th, 2017

At TBits.net, we have decided to use Ansible for setting up our servers.

The most documented way of installing something on a machine via Ansible is using sudo: you create a normal user (eg. called deploy), that you can use with SSH to login to the machine, and if that user has sudo permissions (eg. part of the group wheel in CentOS), then you can install software with root privileges.

The call is quite easy:

ansible-playbook myplaybook.yaml --user=deploy --ask-become-pass

Now we wanted to limit access only to users who have the actual password for root.

Finally, this worked on the command line:

ansible-playbook myplaybook.yaml --user=deploy --become --become-method=su --ask-become-pass

Now, I wanted to specify these parameters in my ansible.cfg file. It took me a while to find out how to do this. I found https://github.com/ansible/ansible/blob/devel/lib/ansible/config/base.yml which was helpful.

[defaults]
remote_user=deploy
 
[privilege_escalation]
become = true
become_method = su
become_ask_pass = true

Two pitfalls that are solved by this:

  • You need to specify the become settings in section privilege_escalation, not just in defaults.
  • The command line parameter ask-become-pass becomes become_ask_pass in the config file.

This works with Ansible 2.3.2 on CentOS 7.4.
