bookmark_borderLatest, Greatest – B1 Systems and Horde LLC on LinuxTag – passwd unofficial H4 package

Posted on by Ralf

This weekend, I visited the LinuxTag exhibition in Berlin, both to support my company’s booth and to talk to the horde guys whose booth was just on the opposite side, allowing easy coordination. As a result, I adopted the passwd tool which hasn’t yet been released for H4. It’s been packaged for the SUSE server:php:applications repository and will be part of the next pre-release of the upcoming Horde 4 Demo VM. First effort was adding a new backend driver ‘horde’ which is just a proxy to horde’s configured authentication backend.

bookmark_borderEverybody talks about Enterprise Clouds as the Next Big Thing!

Posted on by Ralf

Nowadays, everybody talks about Enterprise Cloud Solutions as the next big thing in IT. Actually, it’s a thing from the 1960s. See yourself.

But, seriously, if you were looking for cool cloud solutions featuring OpenStack, better turn to B1 Systems GmbH from Germany.

bookmark_borderHorde 4 Alpha 1 released (pear)

Posted on by Ralf

Yesterday the horde project released alpha versions of Horde Framework 4 and the Groupware apps (Notes, Calendar, Email, Filter,Address Book, Tasks)

I did a test drive and they basically work. IMP has been improved a lot and now integrates the mobile and ajax interface versions which came as separate apps in Horde 3. DIMP (Ajax version) now plays more nicely together with classic non-Ajax horde applications.

I will begin distribution packaging for SUSE Linux around the official release on April 05, 2011.

bookmark_borderDeveloping Hort password safe: Horde 4 Shares

Posted on by Ralf

I recently decided I wanted to drop the Horde 3 password safe eleusis and build something new which uses Horde 4 API and features right from the start.

Thus I got the horde skeleton from git and created a new horde app called “hort”. Hort is an old German word for treasure as well as the place where the treasure is kept. Hort should keep safes which hold user/password pairs or other secret credentials. Those safes should be shareable among users. This is where horde_shares comes into play.

Horde Shares provides an API for sharing access rights like SHOW, READ, EDIT, CREATE or DELETE on objects or containers of objects with other users. Shares is used in the Calendaring App for sharing calendars with other users and in many other places.

basic setup in Application.php _init()

We want to add an injector for the shares API whenever the app is initialized and we want to auto-create an initial “home” share for users which do not yet own one.

 

protected function _init()
{
// Create a share instance.
$GLOBALS['hort_shares'] = $GLOBALS['injector']->getInstance('Horde_Core_Factory_Share')->create();

/* If the user doesn't own a safe, create one. */
if (!empty($GLOBALS['conf']['share']['auto_create']) &&
$GLOBALS['registry']->getAuth() &&
!$GLOBALS['hort_shares']->countShares($GLOBALS['registry']->getAuth())) {
$identity = $GLOBALS['injector']->getInstance('Horde_Core_Factory_Identity')->create();
$share = $GLOBALS['hort_shares']->newShare(
$GLOBALS['registry']->getAuth(),
strval(new Horde_Support_Randomid()),
sprintf(_("Default safe of %s"), $identity->getName())
);
$GLOBALS['hort_shares']->addShare($share);
}

}

And now let’s create the database schema. In Horde 4, this is done by creating a php script in the app’s /migrations/ sub-directory


class HortBaseTables extends Horde_Db_Migration_Base
{
/**

public function up()

$tableList = $this->tables();

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

Posted on by Ralf

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_borderHorde 4 Preview – Calendar Kronolith now supports resources

Posted on by Ralf

Horde 4 is due for April 05 2011 – and sports a new release of the major groupware applications. Among them, the time-tracking app hermes sees its 2.0 release. DIMP (ajax webmailer) and MIMP (mobile devices webmailer) have been integrated into IMP, the webmailer. The task tracker nag has been integrated into the new (optional) ajax frontend of the kronolith calendar app. By the way, Kronolith now allows assigning resources like rooms or beamers to events and provides resource scheduling just as if they were persons. The classic non-ajax interface is still available as a user preference though. Horde 4 won’t be compatible with the generic inventory app sesha anymore. The horde team has decided to abandon some other applications, too Currently, the Horde 4 git repository houses more than 20 applications, ranging from enhanced versions of long-running mainstream apps like the file manager gollem or the VCS chora to Horde Folks, the bleeding edge Facebook-like personal dashboard. Horde 4 will sport the ActiveSync protocol, opening synchronisation options for iPhone 4, Windows Phones and Android smartphones like the Motorola Milestone (Euro Brand) / Droid (US Brand) .

I will be dropping maintainence of Andre Pawlowski’s password safe eleusis in favor of a complete Horde4 rewrite, Hort.

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

Posted on by Ralf

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

Posted on by Ralf

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
