Upgrading Horde Groupware


1   Introduction

These are instructions to upgrade from earlier Horde Groupware versions. Please backup your existing data before running any of the steps described below, you need the backups in case anything goes wrong with the upgrade process, which cannot be reverted automatically. You can't use the updated data with your old Horde Groupware version anymore.

Please see below for changes between certain Horde Groupware versions that are not covered by the update script.

2   Upgrading any Horde Groupware 4 or later

Upgrading Horde Groupware is as easy as running:

pear upgrade -a -B horde/groupware

If you want to upgrade from a Horde Groupware version prior to 4.0, please follow the instructions in INSTALL to install the most recent Horde Groupware version using the PEAR installer.

After updating to a newer Horde Groupware version, you always need to update configurations and database schemes. Log in as an administrator, go to Administration => Configuration and update anything that's highlighted as outdated.

3   Upgrading Horde Groupware from 5.1.x to 5.2

3.1   Base Module

3.1.1   Configuration Options (conf.php)

New logging options for ActiveSync logging have been added. It is now possible to log all devices to a single log file or to device specific files. Additionally, it is also possible to select between including the raw wbxml stream in the output, or prune tag content greater than 50 bytes. The ActiveSync configuration section should be revisited.

It is now possible to use X509 certificates either in addition to, or in place of traditional HTTP Basic authentication for ActiveSync. Refer to the ActiveSync configuration section for more details.

An additional option is now available for the SMTP Mailer driver: 'lmtp'.

A new NoSQL driver is now available for storing ActiveSync device state. Refer to the ActiveSync configuration section for more details.

The History driver can now be explicitly defined in the configuration (and a new NoSQL driver has been added).

Additional options are now available for the Predis HashTable driver: 'password', 'persistent', and 'protocol'. Additionally, the 'hostspec' and 'port' options now accept multiple values (separated by commas).

The following options were added:

It is now possible to configure Horde-wide settings for a NoSQL database backend. Addtionally, several Horde packages now allow a NoSQL backend driver to be used.

The Memcache configuration options have been deprecated and have been replaced by the generic Horde_HashTable package (which supports both Memcache and Redis servers). Although the previous memcache configuration will continue to work in Horde 5.x, it is recommended to upgrade to the new 'hashtable' configuration setup.

5   Upgrading Horde Groupware from 5.0 to 5.0.1

5.1   Base Module

5.1.1   Weather portal block

Google no longer provides a weather API. Support for this has therefore been removed from Horde. If you were using Google as a source for weather, you will need to pick a new provider and update the Horde configuration.

6   Upgrading Horde Groupware from 4.x to 5.x

6.1   Base Module

6.1.1   Configuration Options (config/conf.php)

The $conf['session']['max_time'] option was added. The default is no maximum session time, the same behavior as in Horde Groupware 4.

The $conf['cachecssparams']['url_version_param'] option was added. This option is only used if no CSScaching is selected (a configuration that is NOT recommended for production servers). The new default is to add version information to CSS server URLs, which is altered behavior from Horde Groupware 4.

The $conf['cachejsparams']['url_version_param'] option was added. This option is only used if no javascript caching is selected (a configuration that is NOT recommended for production servers). The new default is to add version information to javascript server URLs, which is altered behavior from Horde Groupware 4.

6.1.2   Hooks (config/hooks.php)

The 'appauthenticated' hook has been added.

The behavior of the 'pushapp' hook has changed - it is now called a maximum of one time per page access for an application.

The 'appinitialized' hook was removed (replaced by the 'appauthenticated' hook).

The 'pushapp_post' hook was removed.

See config/hooks.php.dist for further details.

The 'menu_view' and 'show_sidebar' preferences have been removed.

6.1.4   ActiveSync (EAS) Integration

Support for the EAS 12.0 and 12.1 protocol versions has been added. New configuration options have been added to support this. You MUST update Horde Groupware's ActiveSync configuration.

The Custom logging option has been changed to ALWAYS be a path to a directory, and not a specific filename.

The security policy settings have been moved out of the global configuration and into the permissions system for greater per user control over policies.

New database migrations have been added, you MUST run these migrations for ActiveSync to work.

6.2   Address Book Module

6.2.1   Attributes

  • The "gender" attribute sets values of (literally) "male" or "female" now, and no longer 0 or 1.

6.2.2   Preferences (turba/config/prefs.php)

  • The "addressbooks" preference has been removed.

6.2.3   API Changes

  • search

    The $sources, $fields, $matchBegin, $forceSource and $returnFields parameters have been removed and replaced by the $opts parameter.

    Added a 'rfc822Return' option to return a Horde_Mail_Rfc822_List object instead of the search results array (which remains the default).

7   Upgrading Horde Groupware from 4.0.x to 4.0.4

7.1   Base Module

7.1.1   Weather portal block

The website has dropped their API to retrieve weather forecasts with a very short notice. The portal block has been removed and will be automatically removed from the users' portal configurations too.

A new portal block for weather forecasts is available, powered by the new Horde_Service_Weather library that supports a number of free weather services. To provide this block to the end users, install the Horde_Service_Weather library from Horde's PEAR server, and configure a weather service in Horde Groupware's configuration:

pear install horde/horde_service_weather-alpha

7.1.2   Configuration changes

The 'nobase64_img' option was added.

8   Upgrading a Horde Groupware 1.x

For upgrading from a Horde Groupware version 1.x to 4.0 or later, see the section Upgrading any Horde Groupware 4 or later.

The update script will automatically migrate database backends and update configuration files. It will add new and changed configurations at the end of existing configuration files, any changes done to old configuration files won't get lost, but might get overridden by new settings. You might want to check the updated configuration files after the update script has finished to make sure that any customizations that you did to the old version still work as expected.

The .dist versions of the configuration files alway contain the most recent reference settings and the settings documentation. If you experience any problems with the configuration files after an update, or if you want cleaner configuration files without all the updating code, you can create fresh versions from the .dist files.

These instructions are supposed to be used with a complete tarball of the new Horde Groupware version. They don't work if you use a patch file to upgrade your installation, because the patch already contains all configuration file changes that the update script is going to add.

  1. Extract the tarball of the new version in parallel to the old version. See the INSTALL file details how to unpack a tarball.

    If you want to replace the old version with the new version eventually, you should move the old version to a different place now and put the new version in the place of the old one. You can still do this later, if you want to, but you have to edit the configuration file then.

  2. Start the setup script:

  3. Choose the update option in the setup menu and answer the questions from the setup script.

  4. Pray.

  5. If everything went fine and without any error messages, point your browser to the URL of the new version and log in as an administrator. Go to the Administration -> Setup screen and update all configurations that are marked as being outdated.

  6. If you want to replace the old version with the new one, and if you didn't do this already in step 1, you can do it now. But you have to edit the configuration file config/conf.php manually and change the setting $conf['cookie']['path'] to match the new URL path. Otherwise you won't be able to login after you moved Horde Groupware to a different directory.
