• 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 {{$foo = &new Foo();}} calls and replace with {{$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::.

• 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)

• Remove hack to fix app-specific Notification_Listeners that output

  instead of

• (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 or library.

• 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

• Don't let Horde_Crypt_pgp methods check for secure connection.

• Remove pref_api BC files

++ MIME issues

• Remove deprecated code in MIME_Headers::

• Remove BC mime_drivers code in MIME_Viewer::, IMP_Contents::, MIMP_Contents::.

• Make MIME::_rfc822encode() a public function.

• Make MIME_Viewers responsible for retrieving part contents (so they can determine whether or not contents should be retrieved at all and/or cached).

++ !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 [http://bugs.horde.org/ticket/?id=4221 4221].

• Bug [http://bugs.horde.org/ticket/?id=3271 3271] - more specifically, how to deal with addition of configspecial tags. Of course, this depends on what changes are made to Horde's configuration design.

++ To discuss

• Use Horde_Template for all templates.

• 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/
