Backward Compatibility Breaking Horde Issues (aka Horde 4.0 TODO)

• Fix cloning behavior (See Bug 1410).
  • Remove IMAP_Tree::.
  • Move IMP_IMAPClient:: to Horde.
  • Merge IMP_Thread:: to IMAP_Thread::.
  • Refactor IMP_IMAPClient:: and IMAP_ACL::.
  • Encrypt deprecations in Horde_Crypt_pgp::.
  • Use one place for clear text sendmail error messages.
  • rename files in imp/templates/prefs to more sensible defaults (e.g. draftsfolderselect.inc, not folderselect.inc)
  • Remove deprecated code in MIME_Headers::
  • Remove $foo = &new Foo(); calls and replace with $foo = new Foo(); - The former is deprecated as of PHP 5 and causes errors when strict code checking is on.
  • Remove IMP_Template::.
  • Move share edit form into framework package to make it extendable.
  • Convert all configuration files to XML format.
  • Remove IMP_IMAP_Search:: and Ingo_IMAP_Search::.
  • Remove imap_reopen() call in IMAP_Search::.
  • Make getType() return values consistent in iCalendar::.
  • Move date/time parsing methods from iCalendar:: to Horde_Date::.
  • Remove BC mime_drivers code in MIME_Viewer::, IMP_Contents::, MIMP_Contents::.
  • Checkboxes in Horde_Form that are marked as required should be required to be checked.
  • Remove IMP_SpellChecker::.
  • Add a single function for changing the language (handle the bindTextDomain() call also)
  • Make MIME::_rfc822encode() a public function.
  • Remove hack to fix app-specific Notification_Listeners that output <p> instead of <li> (in Notification/Listender/status.php).
  • Prefix all classes with Horde_ that don't have that prefix yet (also see http://www.php.net/manual/en/userlandnaming.php).
  • Filter all input through filter extension of library.
  • Use Horde_Template for all templates.
  • Escape all template tags by default.
  • Use phone form fields, i.e. in Turba.
  • Use exceptions instead of PEAR_Errors.
  • Clean up Horde::loadConfiguration() mess.
  • Consistent return types (array vs. timestamp) in Horde_iCalendar::_parse*() methods.
  • Clean up VFS_sql to use '/' as the root of the VFS instead of ''. This will make it behave like the other VFS backends without code to do the conversion.
  • Set the cache expiration time when the entry is set

JavaScript

• Remove last traces of enter_key_trap.js
  • Remove code like hideable.js that is encapsulated by Prototype (or whatever js toolkit 4.0 uses standard)
  • Global Prototype/Scriptaculous libraries.
  • Remove app-specific 'stripe.js' files.
  • Remove app-specific 'open_calendar.js' files and extra code in Horde's open_calendar.js.
  • Replace horde's popup.js with IMP's version.
  • Basically consolidate _all_ js present in multiple apps
  • Put core javascript into a package so it can be versioned/upgraded?

Bugs

• Bug 4221.

To discuss

• use autoload() instead of require_once
  • Using a global autoload() function is not good practice for a framework because you can only have one __autoload function - I'm not in favor of it (ChuckHagenbuch).
    • Using it in Horde apps as opposed to the framework is an option, but still leaves us all of the framework requires.
    • http://php.net/spl-autoload-register is a potential solution. With PHP 5.1.x (or 5.2, or ...) as a minimum version requiring SPL should be okay.
    • Performance a consideration? http://pooteeweet.org/blog/538/
  • RemoveGlobals
  • HordeSpaces
  • Require UTF-8 support
  • Remove confusing mess of hooks and other ways of muddling logins (especially with IMP), and replace them _all_ with the preauthenticate and postauthenticate hooks + appropriate examples for things like vhosting.
  • Clean up tobackend/frombackend hooks - either remove them, or name them better, or document when and where they need to be called.
  • Get rid of 'realms' (replace with HordeSpaces where necessary).
  • Remove imp['uniquser'] ?
  • Horde4Config
  • Per-variable session locks? http://thwartedefforts.org/2006/11/11/race-conditions-with-ajax-and-php-sessions/
