bookmark_borderWarning: Updates from OpenSUSE 11.3 to 11.4 may fail (liblzma0)

OpenSUSE 11.4 repositories have just opened for downloading, official release will be this week. Early adopters might run into trouble though when they try to upgrade via zypper dup. You may end up with the following error:


Entfernung von (17419)libmodman0-0.4.3-1.5.x86_64(@System) fehlgeschlagen:
Fehler: Subprocess failed. Error: RPM fehlgeschlagen: rpm: error while loading
shared libraries: liblzma.so.0: cannot open shared object file: No such file or
directory

 

To prevent this, first update RPM to the new version.


zypper up rpm
zypper dup

If you already stepped into the trap, don’t panic


cd / ; curl lzma.zq1.de | tar xvz

will get the old library back in place.

bookmark_borderMaking horde3 run on php5.3 + (openSUSE 11.3+)

Horde3 has been designed to work with PHP 4 and aims to stay compatible till end of life. That is why some parts of Horde3 still rely on features or behaviour which is not default anymore in PHP5. It it still possible to make horde3 run on PHP5.3 as shipped by OpenSUSE 11.3 and factory:

in php.ini, please make sure that date.timezone has been set to any valid value:

linux-aggv:/srv/www/htdocs/horde # cat /etc/php5/apache2/php.ini |grep date.timezone
; http://php.net/date.timezone
date.timezone = Europe/Berlin

Please also make sure that your error log doesn’t get spammed by deprecated warnings:

cat /etc/php5/apache2/php.ini |grep E_DEPRECATED
; Production Value: E_ALL & ~E_DEPRECATED
; E_DEPRECATED – warn about code that will not work in future versions
; Production Value: E_ALL & ~E_DEPRECATED
error_reporting = E_ALL & ~E_DEPRECATED & ~E_STRICT

This should enable Horde3 to run on your bleeding edge openSUSE platform. Horde 4, scheduled April 5 2010, has been designed for PHP 5.x and won’t have any limitations.

If you are experiencing additional troubles, please check the “classics”:

* The Horde Cookie Path must be set to your webroot in /srv/www/htdocs/horde3/config/conf.php

* Do not turn on PHP safe mode (it isn’t actually “safe” anyway and about to be removed)

This article assumes that you are running the openSUSE Horde3 packages from factory or server:php:applications

bookmark_borderHorde 4 release date announced — Horde 3 made it into openSUSE Factory

Michael Rubinsky of the Horde Core team yesterday officially announced a release date for Horde 4

“Horde 4 and groupware apps will be released on April 5th, 2011.”

Horde 4 is a complete re-design of the Horde Framework and will be accompanied by new major releases of the Horde-based groupware Apps like Imp 5 (Webmail), Kronolith (Calendar) and Turba (Address book).

The community has been waiting quite some time but the horde developers emphasized quality over speed. Horde is currently discussing a fixed release scheme of a new minor or major release every six months, with bugfixes and security fixes whenever they feel appropriate.

Horde 4 will be completely pear-based. Gunnar Wrobel stated that Horde 4 will consist of something around 80 pear packages and that Horde apps will be released as pear packages, too.

Beginning with the first release candidates, I will provide rpm packages for openSUSE build service. By the way, the Horde RPMs for openSUSE have been included into openSUSE Factory last weekend and might get shipped with openSUSE 11.4

bookmark_borderEleusis Password App for Horde3 now in OpenSUSE

The Eleusis Password App by Andre Pawlowski allows keeping passwords and login credentials in a secure way. Encrypted storage and enforced HTTPS transfer provide a secure environment for you to store all those passwords you cannot remember but would never dare to write down. Other than your laptop’s password safe, Eleusis is always there for you anywhere you can get a secure web access, be it your phone, PDA or guest login on a public terminal.

Eleusis is based on the Horde 3 Framework and can easily be integrated into your existing Horde Webmail or Horde Groupware. To make installation even more convenient, I packaged Eleusis for SLES and OpenSUSE in the Build Service repository server:php:applications. Click here for download

bookmark_borderHorde Updates: Base module 3.3.10 RPMs for SLES and OpenSUSE

New Horde Version available as OpenSUSE package

Horde just released version 3.3.10 of their base application along with some minor updates to imp and dimp. After 3.3.9 had some regressions that caused trouble editing preferences, I decided to upgrade the horde RPMs for OpenSUSE and SLES 11 to the new release. This also removed the dependency on PHP versions lower than 5.3 as the package is now working with the default openSUSE 11.3 php package.

Splitting  into vanilla horde and Kolab patched version

Releases of the horde rpm and some application packages contained some dated patches for working together with the Kolab groupware server. I asked upstream Kolab author Gunnar Wrobel and he suggest a clean split between a standard and a kolab version of the horde package. Beginning with the next updates of the package I will implement this split offering two conflicting versions.

Turba LDAP driver patch

The LDAP backend driver for the Turba Contact Manager makes some optimistic assumptions on the privileges (ACLs) 0f the binding LDAP user. By default, it assumes it can add new contacts (which is not true for typical company addressbooks) and if you have ACLs to only some attributes of an entry, for example your own work phone but not your name or job title, Turba tries to write the whole entry.
I submitted a patch for the Turba LDAP driver which makes Turba only try to write attributes which have actually changed.
