UPGRADING
================= Upgrading Horde ================= :Contact: horde@lists.horde.org .. contents:: Contents .. section-numbering:: General instructions ==================== These are instructions to upgrade from earlier Horde versions. Please backup your existing data before running any of the steps described below. You can't use the updated data with your old Horde version anymore. Upgrading Horde (and all installed Horde libraries and applications) is as easy as running:: pear upgrade -a -B -c horde If you want to upgrade Horde with all binary dependencies, you need to remove the ``-B`` flag. Please note that this might also try to install PHP extensions through PECL that might need further configuration or activation in your PHP configuration:: pear upgrade -a -c horde If you want to upgrade to an alpha or beta version of Horde, you need to tell the PEAR installer to prefer non-stable package versions. Please note that this might also install pre-release 3rd-party PEAR packages:: pear -d preferred_state=alpha upgrade -a -c horde If you want to upgrade from a Horde version prior to 4.0, please follow the instructions in INSTALL_ to install the most recent Horde version using the PEAR installer. After updating to a newer Horde version, or a newer version of **any** Horde application, 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 Configuration and update anything that's highlighted as outdated. Upgrading Horde from 5.1.x to 5.2 ================================= 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:: $conf['activesync']['logging']['level'] $conf['activesync']['auth']['type'] $conf['activesync']['auth']['params'] $conf['activesync']['storage'] $conf['activesync']['params']['driverconfig'] $conf['cachecssparams']['filemtime'] $conf['history']['driver'] $conf['history']['params']['driverconfig'] $conf['mailer']['params']['password_auth'] $conf['mailer']['params']['username_auth'] The available options for the following options were changed:: $conf['activesync']['logging']['type'] $conf['mailer']['params']['password'] (for SMTP) $conf['mailer']['params']['username'] (for SMTP) The default value for the following options were changed:: $conf['prefs']['maxsize'] The following options were removed:: $conf['mailformat']['brokenrfc2231'] Hooks (hooks.php) ----------------- New ActiveSync related hooks have been added:: activesync_create_device activesync_device_check activesync_device_modify Read the comments at the top of the hooks.php file for descriptions of each hook. Registry Options (registry.php) ------------------------------- The 'staticfs' and 'staticuri' configuration options were added to the 'horde' configuration. Upgrading Horde from 5.0.x to 5.1 ================================= Configuration Options (conf.php) -------------------------------- 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. The following options were added:: $conf['auth']['resetpassword_from'] The following options were removed:: $conf['cache']['compress'] $conf['cachecssparams']['compress'] Hooks (hooks.php) ----------------- The 'ajaxaction' hook has been deprecated and replaced with the 'ajaxaction_handle' hook (new hook needed in order to allow, e.g., adding tasks to the outgoing response). The following hooks were added:: ajaxaction_data Upgrading Horde from 5.0 to 5.0.1 ================================= 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. Upgrading Horde from 4.x to 5.x =============================== Configuration Options (conf.php) -------------------------------- The $conf['session']['max_time'] option was added. The default is no maximum session time, the same behavior as in Horde 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 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 4. Hooks (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. Preferences (prefs.php) ----------------------- The 'sending_charset' preference now defaults to 'UTF-8'. Any previous saved value will be deleted when upgrading to 5.0 - if you want to send in a charset other than UTF-8 (NOT RECOMMENDED), you will need to explicitly set this value again (in either ``config/prefs.local.php`` or you preferences storage backend). The 'menu_view' and 'show_sidebar' preferences have been removed. ActiveSync (EAS) Integration ---------------------------- Email support has been added, along with support for the EAS 12.0 and 12.1 protocol versions. New configuration options have been added to support this. You MUST update Horde'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. Upgrading Horde from 4.0.x to 4.0.12 ==================================== Weather portal block -------------------- The weather.com website has dropped their API to retrieve weather forecasts with a very short notice. The weather.com 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's configuration:: pear install horde/horde_service_weather-alpha Upgrading Horde from 4.0.x to 4.0.10 ==================================== Configuration changes --------------------- The 'nobase64_img' option was added. Upgrading Horde from 4.0 to 4.0.1 ================================= Configuration Values -------------------- Cyrsql driver: The 'unixhier' parameter has been replaced by the 'userhierarchy' parameter. Hooks ----- The appinitialized hook was added. See ``config/hooks.php.dist`` for more details on this hook. Upgrading Horde from 3.3.x to 4.x ================================= New installation method ----------------------- Since Horde 4 the supported installation method has been changed to install Horde and all dependencies through the PEAR installer. See INSTALL_ for instructions how to install Horde through PEAR. Existing **data** from the latest Horde can be migrated from the configuration screen in the administration section. It is recommended to re-create the **configuration** from scratch though. New configuration scheme ------------------------ With Horde 4 it is no longer necessary to create any configuration files besides ``conf.php`` files. The default configuration files in the ``config/`` directory should work for most systems. If some changes in those files are necessary, **DON'T EDIT THE FILES DIRECTLY or your CHANGES WILL BE LOST with the next upgrade**. Create ``*.local.php`` files instead and only add configuration settings that you want to change from the default values there. See the header of the configuration files for details and examples. ``conf.php`` files are still created and updated as usual through the configuration interface. New database migrations ----------------------- With Horde 4 database updates are no longer done by running SQL scripts through your database server's console or web frontend. A migration framework has been created instead that can be used through the web interface and a command line script. After updating, log in to Horde as an administrator, make sure that all configurations are up-to-date, then click on the ``Update all DB schemas`` button. You can also update the database schemas individually if necessary. Alternatively there is a command line script ``horde-db-migrate`` that can be used for upgrading the database schemas. Call it without any parameters to upgrade schemas for all installed applications and components, or specify the application, component, or ``migration/`` directory that you want to upgrade individually. PostgreSQL ---------- If using PostgreSQL, you must upgrade the value column of the preference table from TEXT to BYTEA **before** running any other upgrade tasks. The necessary SQL statement is found at:: scripts/upgrades/2009-04-13_horde_pgsql_upgrade.sql Configuration changes --------------------- Many configuration names and values have changed. It is suggested that you start with a fresh configuration instead of trying to import some existing configuration from Horde 3. Preferences ----------- The following preferences are no longer used and can be removed from the horde_prefs table if you want to save database storage: * confirm_maintenance * do_maintenance * editor_plugins * last_maintenance Hooks ----- The hooks format has been changed completely. ``hooks.php`` no longer contains separate functions for each hook, but a single class with separate methods for each hook. Please take a look at the new examples in ``hooks.php.dist`` before porting any hooks to Horde 4. Some hook signatures have changed, some hooks have been renamed, removed or added. Noteably the following hooks have changed: * "preauthenticate" (Parameters and return value have changed) * "postauthenticate" (Parameters and return value have changed) * "username_tobackend", "username_frombackend" (Have been combined and renamed to "authusername") * There are only two methods prefs_init() and prefs_change() for all preferences. Alarms ------ The alarm system is using UTC dates now. This can cause problems for a short time after updating to Horde and before the alarms have been refreshed. To avoid any problems you should empty the horde_alarms table after upgrading manually. This SQL query should work:: DELETE FROM horde_alarms The script to generate alarm notifications through a cron job (``scripts/alarms.php``) has been renamed and is installed to a different location when using the PEAR installation method. The new name is ``bin/horde-alarms`` and it will be installed to ``/usr/bin/horde-alarms`` by default. Update your cron jobs accordingly. Groups ------ The groups system has been rewritten. Group hierarchies, i.e. parent and child groups are no longer supported. Support for nested groups will be added at a later point. PEAR packages ------------- The Crypt_Blowfish package is required now. If you installed Horde using the PEAR installer, it will be installed automatically though. Removed features ---------------- * Database abstraction has been moved to a new Horde_Db component. Any database support beside MySQL (native and PDO), PostgreSQL, and SQLite have been removed. If you need support for any other RDBMS, consider sponsoring the development of new drivers for that system. * DataTree support has been removed. Several systems used DataTree as a possible backend for historical reasons. If you still used DataTree backends in Horde 3 and didn't migrate to SQL drivers yet, now you have to. See further below for instructions how to migrate away from DataTree backends. * The krb5 authentication driver has been removed. * The LDAP session handler has been removed. * The enscript and webcpp MIME Viewers have been replaced by the 'Syntaxhighlighter' driver. Upgrading Horde from 3.3.x to 3.3.5 =================================== The signup_email column of the horde_signups table is no longer needed. You can execute the provide SQL script to remove that column, e.g.:: mysql --user=root --password=<MySQL-root-password> <db name> < scripts/upgrades/3.3_to_3.3.5.sql Upgrading Horde from 3.2.x to 3.3.x =================================== The sequence name for the SQL share driver has been changed from 'sequence' to 'id' You must execute the provided PHP script to update your database:: php scripts/upgrades/2008-08-29_fix_mdb2_sequences.php Note that this upgrade will require you to have the PEAR MDB2_Schema package installed on your system:: pear install MDB2_Schema Upgrading Horde from 3.1.x to 3.2.x =================================== SQL Backends ------------ A few new tables have been added to Horde. Execute one of the provided SQL scripts to update your data to the new Horde version, e.g.:: mysql --user=root --password=<MySQL-root-password> <db name> < scripts/upgrades/3.1_to_3.2.mysql.sql Beta SQL Drivers ---------------- There are now beta-level SQL drivers for Groups, Shares, and Permissions. There is a script ``horde-convert-datatree-perms-to-sql`` that will migrate all of your DataTree-based permissions to the SQL backend, and ``horde-convert-datatree-groups-to-sql`` that will migrate groups. For shares, you will need to upgrade each application individually. Applications that use shares have entries in ``docs/UPGRADING`` and upgrade scripts ``app-convert-datatree-shares-to-sql`` for creating the SQL share tables and migrating data. The SQL drivers should perform much better than the DataTree versions, but they have not received the same level of testing, thus the beta designation. Memcache Configuration ---------------------- All memcache configuration has been moved to the $conf['memcache'] parameter. Application Hooks ----------------- All hooks that are specific to a single application have been moved to that application's ``config/hooks.php`` file. Split up your existing Hooks from ``horde/config/hooks.php`` and move them to the correct application. Group Hooks ----------- The format for group hook functions has changed from _group_hook_groupName($username) to _group_hook($groupName, $userName). So you will need to modify any existing group hook functions in config/hooks.php for the new interface. Alternatively, an example _group_hook() function is provided in config/hooks.php that will call the old style hook functions for you. Custom Themes ------------- Themes only have a single ``info.php`` file with the theme name in Horde's ``themes`` directory now. If you have any custom themes that provide their own images, you must add a ``themed_graphics`` file to the theme's directory (for all applications the theme provides images for) in order for Horde to know to use the custom images. The file can be empty or contain whatever you wish; it simply needs to exist. Static Log out Links -------------------- If you have hardcoded a log out link in any custom templates or menu items, you must update it to use Horde::getServiceLink(). This is because logging out is now protected by a token to avoid CSRF exploits. Upgrading Horde from 3.1.1 to 3.1.2 =================================== Session Configuration --------------------- A new configuration setting has been added to disable GET-based sessions. If this setting is enabled, session IDs will only be stored in session cookies, requiring the users to enable cookies in their browser and the cookie settings in Horde's configuration to be correct. Using session cookies is much safer since no session information can be stored in any web server or proxy log files, referrer headers, browser caches, or browser bookmarks. .. Warning:: This setting in enabled by default. Additional Indexes for the Preference Table ------------------------------------------- Optionally execute the provided SQL script 2006-06-29_horde_prefs_indexes.sql to create two additional indexes in the preference table, e.g.:: mysql --user=root --password=<MySQL-root-password> <db name> < scripts/upgrades/2006-06-29_horde_prefs_indexes.sql This increases database performance for some database systems, e.g. PostgreSQL if you have large preference tables. Upgrading Horde from 3.1 to 3.1.1 ================================= MySQL Session Handler --------------------- The mysql session handler has been improved to correctly lock concurrent accesses to the same session. You need to set in the Horde configuration if you want to use row-level locking and transactions or table-level locking. Row-level locking and transactions are only supported by some table engines like InnoDB, and is recommended for session tables. The default table type for MySQL is MyISAM though, that only supports table-level locking. If you used the SQL scripts from Horde 3.1 or earlier to create the session table, this is probably the current engine of you session table. If you want to change the table type to InnoDB, execute the following SQL statement:: ALTER TABLE horde_sessionhandler ENGINE = InnoDB Upgrading Horde from 3.0.x to 3.1.x =================================== SQL Backends ------------ A few new tables have been added to Horde. Execute one of the provided SQL scripts to update your data to the new Horde version, e.g.:: mysql --user=root --password=<MySQL-root-password> <db name> < scripts/upgrades/3.0_to_3.1.mysql.sql Groups ------ The Horde_Group API uses group IDs instead of group names to avoid ambiguity. Be sure to update any custom code that uses Horde_Group. History ------- The Horde_History storage has been moved out to a separate database table to drastically improve performance. .. Warning:: Migration of the Horde_History data may take a very long time, possibly days, depending on the number of entries. Be sure to execute this script from a location where it will not be timed out by firewall or terminal timeouts. Execute the provided PHP script to migrate your histories to the new table:: horde-move-history-out-of-datatree .. _INSTALL: INSTALL
