- The language field can be a language code for a single language, or "*" to be displayed for all languages
- Community extension for language maintenance com_localise
New installation types
- Must include an XML manifest where type="library"
- Can only be installed into a sub-folder of /libraries/
- Can extend parts of an existing library, eg /libraries/joomla/database/database/oracle.php
- Must include an XML manifest where type="package"
- A package is a zip of zip's
New install script can be provided with 5 methods:
- Runs before anything is run and while the extracted files are in the uploaded temp folder
Could allow for:
- secondary extraction of custom zip's
- version checks to be performed
- halting the installer on an error
install / update
- Runs after the database scripts are executed
- If the extension is new, the install method is run
- If the extension exists then update method is run if method="upgrade", otherwise assumes that the extension is not meant to be upgradable
- Runs after the extension is registered in the database
- Is not run for the uninstall process (nothing left to do obviously)
- Does not do any file copying, only works with what it finds
- Performs preflight, install and postflight
- Developer of installer has two language files??
- Can publish an XML manifest on your site that can include individual extensions and extension sets.
XML Manifest Changes
- <install> is deprecated - use <extension>
- New <update> tag. Takes a <schemas> tag which can define <schemapath>
- <params> and <param> tags are deprecated, use <fields>, <fieldsets> and <field> instead
- Installation manifest must be the same name as the extension, eg com_foobar/foobar.xml This helps with discovery (otherwise the function has to go through all the files in the extension folder
- Plugins are now in folders like modules and components
- See SVN/tests/_data/installer_packages/ for complete examples of all extensions and manifests.
- The method="upgrade" will compare individual files in the original and incoming manifests and will remove files as appropriate. However, it will not remove differences in the <folder> tags.
- Future support for rollback
- All content events (except for search and search areas) now pass a 'context' as the first argument to alert the plugin as to what type of content is being passed. The plugin event may or may not heed this context.
- Component can provide custom options for its own categories via optional category.xml
- Supported via JTableNested
- A thing that can be controlled by permissions is registered in the assets table
- JTable handles this transparently via asset_id field
- For view permissions, support is as simple as adding
- $user = JFactory::getUser();
- $groups = implode(',', $user->authorisedLevels());
- $query->where('a.access IN (' . $groups . ')');
For action permissions, same format as in 1.5: $user->authorise($actionName, $assetName)
- OpenID library moved to plugin folder
- Geshi library moved to plugin folder
- JRegistry notes defaults to JSON (new format), dynamically converting existing data in INI format
- New JStream
- New JApplicationHelper::getComponentName
- Core icons moved to /media/
- Backward incompatible change to JEditor::display
- Added chaining support to JMail
- JFilterInput can no longer be called statically
- JHtml::image now supports relative paths
- All system images are overridable in the default template
- New JHtmlString
- Added wincache session handler for IIS
- New JFilterOutput::stripImages
- JPath::check takes second arg for separator (to pass to JPath::clean)
- Expanded configuration support through config.xml (multiple tabs)
- Miscellaneous changes
- More tools for assisting with translation
- Need to use document.id instead of $
API changes relevant to 3rd party developers
Component view cache
Component view cache now takes an array of url parameters and their types to create Cacheid. This is a replacement for a previous unsafe way which took the whole URL for this and so opened the doors for DOS attacks via random url parameters added to request URL's.
$safeurlparams = array(
Old cacheid created from URL was retained for backwards compatibility and takes effect if there are no $safeurlparams.
This has been completly reconceptualized. Module cache now has 5 different modes of operation, 3 of them are to be set from module XML file, while 2 are meant to be used from within the module itself. Default is backwards compatible oldstatic mode that requires no changes to a module.
Modes to be set in XML:
- static - one cache file for all pages with the same module parameters
- oldstatic - 1.5. definition of module caching, one cache file for all pages with the same module id and user aid. Default for backwards compatibility
- itemid - changes on itemid change
In addition to cache field that was required in 1.5 there is now another hidden field called cachemode that sets any of the above modes.
<field name="cachemode" type="hidden" label="" default="static">
Modes to be called from inside the module:
- safeuri - id is created from $cacheparams->modeparams array, the same as in component view cache
- id - module sets own cache id's
To use this modes one must rename cache field in xml to owncache field and call JModuleHelper::ModuleCache from within the module's main php file. This is actually a shortcut to cache callback to avoid code duplication in every module.
An example that uses safeuri mode and replaces uncached $list = modRelatedItemsHelper::getList($params) :
$cacheparams = new stdClass;
$cacheparams->cachemode = 'safeuri';
$cacheparams->class = 'modRelatedItemsHelper';
$cacheparams->method = 'getList';
$cacheparams->methodparams = $params;
$cacheparams->modeparams = array('id'=>'int','Itemid'=>'int');
$list = JModuleHelper::ModuleCache ($module, $params, $cacheparams);
Cache administration (Clean cache, Purge cache) now works with all drivers, not only with file cache. New standalone garbage collect script that is to be called from crontab has been added. It can be found in libraries/joomla/utilities/garbagecron.php . For safety reasons it is recommended that it is renamed to something unique.
CMS and framework level functional changes
Caching is implemented in all components and modules that can potentially gain from cache. Caching has also been added to some most expensive and frequent framework calls JComponentHelper::_load(), JModuleHelper::_load(),JMenuSite::load();
Cache library changes
Cache library has been completely refactored.
- Cache handlers have been renamed to controllers to better reflect their role and avoid confusion with cache storage handlers (referred to as drivers in following text).
- New JCacheController parent class has been added and inheritance has been changed to prevent bugs occurring from controller's and storage handler's get method clashes.
- getAll() method was added to JCache, JCacheStorage and all drivers, and it returns all cached items (this was previously possible only with file driver and hardcoded in administration)
- New lock and unlock methods were added to JCache, JCacheStorage and drivers. They enable cache item locking and unlocking to prevent errors on parallel accesses and double saves. This functionally was also implemented in controllers.
- Workarounds are now consolidated in new JCache getWorkarounds and setWorkarounds methods, are now used by all controllers and their use has been made optional.
- New makeId() method in JCache that creates cache id from registered url parameters set by components and system plugins
New parent class to Controllers that also functions as an intermediate to JCache. There is no JObject inheritance as otherwise magic __call doesn't work. Change was needed to prevent bugs occurring from controller's and storage handler's get method clashes. They could be renamed but this would break backwards compatibility.
- _getCacheId method was moved from drivers to their parent JCacheStorage and all drives now use the same method by default
- CacheItem was moved from cache admin to framework JCacheStorageHelper, it is used by getAll
- There are new cachelite and wincache drivers. All other drivers have been fixed with missing functions (gc, clean) added, their code cleaned and tested they should be now working properly.
- Replaced separate _expire files in filecache driver with timestamps (this should amount to cca. 40% speed gain). The same in all drivers that had this.
- Numerous bugfixes on all levels, most important is proper use of options defaulting to configuration parameters settings and correctly passing from level to level.
Other framework level changes
- Safe url parameters registration added to JControler view method.
- New ModuleCache method in JModuleHelper that performs the above described module cache (in 5 modes) for both, modules and module renderer.
- JFactory::getFeedParser has been changed to use Joomla caching instead of simplepie's.
Eliminate the usage of JTable for general browsing on the frontend
- Session drops the usage of JTable
- Item views use a dedicated question, not JTable->load
