Upgrading Seagull from a 0.4.x install to 0.6.x

0.6.0RC2

• all tasks consolidated in lib/SGL/Tasks directory

0.6.0RC1

• filter chain formalised in Front Controller
• filters now take $output as well as $input as arguments

0.5.6

• moved all blocks within their respective modules
• moved all default templates within modules
• renamed PageMgr? to SectionMgr?
• SGL_UrlParser_SefStrategy::resolveArrayElems renamed to SGL_Url::querystringArrayToHash
• in templates, any time a check was done for {if:isAdmin), i've changed it to correctly reflect the method in Output, ie, {if:isAdmin()}
• blocks can now be passed params, see trunk/modules/block/classes/blocks/Navigation.ini for an example
• SGL_AppController renamed to SGL_FrontController
• SGL_HTTP_Session renamed to SGL_Session
• SGL_HTTP::redirect(array()); cleaned up to SGL_HTTP::redirect();

0.5.5

• instantiating a cache object has changed from $cache = & SGL::cacheSingleton(); to $cache = & SGL_Cache::singleton();
• likewise, SGL::clearCache() has changed to SGL_Cache::clear()
• added SGL_Error class in Misc.php
• renamed lib/SGL/Other.php to Misc.php
• added SGL_VAR_DIR, SGL_ETC_DIR and SGL_APP_ROOT to allow for a more flexible pear installation

0.5.4

• the following url parsing strategies are now enabled by default, classic querystring, standard Seagull SEF, and now UrlAlias. That means the all these URLs are valid for the same page
  • http://localhost/seagull/trunk/www/index.php/publisher/articleview/frmArticleID/1/staticId/6
  • http://localhost/seagull/trunk/www/index.php?moduleName=publisher&managerName=articleview&frmArticleID=1&staticId=6
  • http://localhost/seagull/trunk/www/index.php/content-reshuffle-alias/
• at the time of writing aliases are hard-coded in seagull/lib/data/ary.uriAliases.php but shortly they will be coming from the DB, user configurable, and cacheable

0.5.3

• rewritten installer, all routines are task-based
• global config file renamed to <host_name>.conf.php
• only minimum required modules registered: default, user, navigation
• blocks now displayed according to role of current user
• all SQL-related files that used to live in seagull/etc have been moved to 'default' module as that's what they were, default
• item* tables and data moved to publisher
• category table and data moved to publisher
• $this->module = 'foo' no longer need in each Manager's constructor
• installed flag renamed from INSTALL_COMPLETE to INSTALL_COMPLETE.php and now contains a password required access installer
• New wizard can only be accessed if admin knows password stored in seagull/var/INSTALL_COMPLETE.php. Installer is invoked automatically on first seagull install, and can be called manually by calling setup.php
• removed constants.php and init.php so last few 'procedural' LOC are gone, now you only need AppController?.php
• all web tests moved to their own modules
• Moved all core classes that doubled up with other classes to reduce file loading to seagull/lib/SGL/Other.php. Currently this contains SGL_Array, SGL_Date and SGL_Inflector. Should make libs easier to find: if you don't see a file named the same as the lib you want, it will most likely be in Other.php
• added source:trunk/lib/SGL/ServiceLocator.php, this should always be used for getting a database resource, and if you need to use multiple db resouces they should all be registered here, see SGL_Manager constructor to see how it's initialised

0.5.2

• the $conf variable is always available as a class variable in all Managers as $this->conf
• all Managers must fire their parents' constructor: parent::SGL_Manager()
• the $dbh database resource variable is always available as a class variable in all Managers as $this->dbh
• it is no longer possible to assign config values with the old syntax, ie, $conf['foo']['bar'] = 'baz'; you must now use: $c->set('foo', array('bar' => 'baz']; with a singleton config instance, ie $c = &SGL_Config::singleton();
• Request object now stored in SGL_Registry ($input), along with currentUrl, config objects
• SGL_HTTP_REQUEST renamed to SGL_Request
• $GLOBALS_SGL?REQUEST? discontinued in favour of true singleton
• moved resolution of $_SERVERPHP_SELF? to SGL_URL::resolveServerVars($conf) in constants.php
• SGL_Url now uses a parser strategy and can handle seagull urls as well as traditional
• getSignificantSegments changed to toPartialArray
• SGL::getTime moved to SGL_Date::getTime
• all class/method name transformations now done with SGL_Inflector, this is physically located in the seagull/lib/SGL/~Request.php file to reduce file ~I/O. Familiar methods include
  • caseFix
  • getManagerNameFromSimplifiedName
  • getSimplifiedNameFromManagerName
  • getTitleFromCamelCase
  • isMgrNameOmitted
  • isUrlSimplified
  • urlContainsDuplicates

0.5.1

• optional block type that's stored in the DB

What's New

• rewritten installer
• a new SGL_Config class for easy loading of config files, file type discovery and data format handled silently; ini, php array and xml types currently implemented
• an improved SGL_Request object that internally resolves HTTP and CLI request types
• a new SGL_URL object derived from PEAR's Net_Url that abstracts and organises various url formats, classic querystring and Seagull's Search Engine Friendly format are currently supported
• a new flexible SGL_View object that integrates with the template engine of your choice and supports customised workflow for HTML and XML output (read: easy support for PDA output). Flexy is still the default but hooks now exist for Smarty or any other OO engine.
• customisable pre and post process pipelines discussed earlier here.
• use of global vars almost completely eliminated
