TWiki Release 4.1 (Edinburgh), 17 Jan 2007

Introduction

TWiki Release 4.1 is a minor release. TWiki releases are either major (major new features and changes in architecture), minor (enhancements and bug fixes), or patch releases (bug fixes only) which can be installed as upgrades on production installations.

TWiki Release 4.1 introduces some good enhancements and quite many bug fixes since 4.0.5. It requires some manual work to upgrade from TWiki 4.0.5 to 4.1.0. Depending on the tailoring you have made it may take between 10 minutes to two hours to do an upgrade. If you have not made any changes to the skins the upgrade is for sure an effort that takes less than 30 minutes.

The development team has done everything to maintain full compatibility with topics generated in TWiki-4.0 and there are no changes to the topic format.

New Features Highlights

  • Easier Installation and Upgrade
    • Plugins can now be installed from the configure script.
    • The loading of plugin preferences settings has been moved earlier in the preferences evaluation order so that plugin settings can be redefined in Main.TWikiPreferences, WebPreferences and in topics. To make TWiki upgrades easier, it is recommended to set the plugin settings in Main.TWikiPreferences, and not to customize the settings in the plugin topic. For example, to change the TEMPLATES setting of the CommentPlugin, create a new COMMENTPLUGIN_TEMPLATES setting in Main.TWikiPreferences.
    • Plugin settings can now be defined in configure instead of in the plugin topic (requires that the individual plugin has implemented this). TWiki performs slightly better by not looking for preferences settings in plugin topics.
    • Configure no longer shows many unnecessary errors when run first time.
    • The webmaster email address is now defined in configure instead of TWikiPreferences.
    • Default file access rights in the distribution package have been changed to be more universally defined and in line with the default access rights for new topics.

  • Usability Enhancements
    • Redesigned result page when typing incomplete topic name into the Jump box, so that it is possible to quickly navigate to a topic, also in a very large TWiki installation. For example, "I know there is a topic about Ajax somewhere in the Eng web. OK, let my type Eng.ajax into the Jump box... Here we go, the third link is the AjaxCookbook I was looking for."
    • Many user documentation improvements.
    • URL parameters maintained in Table of Contents links so you can stay in a temporary skin (e.g. print) and keep URLPARAM values when you click the TOC links
    • Attachment tables now sorted alphabetically.
    • Better printing of tables and verbatim text in PatternSkin.

  • Application Platform Enhancements
    • Auto-incremented topic name on save with AUTOINC<n> in topic name; used by TWiki applications to create topic based database records.
    • The edit and save scripts support a redirectto parameter to redirect to a topic or a URL; for security, redirect to URL needs to be enabled with a {AllowRedirectUrl} configure flag.
    • CommentPlugin supports the redirectto parameter to redirect to a URL or link to TWiki topic after submitting comment.
    • The topic URL parameter also respects the {AllowRedirectUrl} configure flag so redirects to URLs can be disabled which could be abused for phishing attacks.
    • The view script supports a section URL parameter to view just a named section within a topic. Useful for simple AJAX type applications.
    • New plugin handler for content move.
    • Enhancements for Ajax based applications with TWiki:Plugins/YahooUserInterfaceContrib and TWiki:Plugins.TWikiAjaxContrib (available at twiki.org).

  • Search Enhancements
    • METASEARCH handles a format parameter like SEARCH.
    • Topic not found / WebTopicViewTemplate search now case insensitive.
    • FormattedSearch header supporting $nop, $quot, $percnt, $dollar.
    • Add search by createdate option to SEARCH.
    • New newline option for SEARCH to protect e.g. formfields from being altered during rendering in SEARCH.

  • Skins and Templates Enhancements
    • Support for templates to have text rendering affecting aspect outside of textarea.
    • Pattern skin dependence on TwistyPlugin instead of TwistyContrib (performance improvement.)
    • Don't strip newlines from the front of TMPL:DEFs.

  • Miscellaneous Feature Enhancements
    • Change in WikiWord definition: Numbers are treated as lower case letters, e.g. Y2K is now a WikiWord.
    • Configurable template load path. Advanced feature for those that work with customized templates.
    • Added %VBAR% to TWikiPreferences for vertical bar symbol.
    • On topic creation, force initial letter of topic name to be upper case.
    • Allow date format in form fields.
    • Enhance REVINFO{} variable with same date qualifiers as GMTIME{}.
    • WebTopicCreator - adding ability to select a template from any topic name ending in ...Template
    • Functionality of DateFieldPlugin merged into core

  • Enhancements of Pre-installed Plugins
    • CommentPlugin: Supports removal of comment prompt after a comment is made.
    • EditTablePlugin: Default date format based on JSCalendarContrib instead of plugin topic.
    • InterwikiPlugin: Supports custom link formats.
    • SlideShowPlugin: Preserves URL parameters in slideshow
    • SpreadSheetPlugin: New functions $LISTRAND(), $LISTSHUFFLE(), $LISTTRUNCATE().
    • TablePlugin: New attribute cellborder.
    • TablePlugin: Highlight the sorted column with custom colors; includes also a general cosmetic update of default colors.
    • TablePlugin: Support for initsort on more than one table. A table with the initsort option is initsorted UNLESS it is sorted by clicking on a column header. If you click on a header of another table all other tables goes back to the default sort defined by initsort or not sorted if no initsort, and the new table is sorted based on the user clicking on a table header.

Deprecation Notice

  • Usage of TWikiForms for setting preferences has been deprecated in favor of TWiki:Plugins.PreferencesPlugin. PreferencesPlugin has been included since TWiki 4.0.0 to allow more convenient editing of preferences. This plugin provides input controls, such as menus, radio buttons, and checkboxes to select preference settings.

Bug Fix Highlights

  • User Topics
    • Unused settings on users home topic removed. (no need to update existing user topics - they are still compatible with all features.)
    • An attribute column has been added to the UserForm used on users home topic. If you tailored this form just continue using your existing form.

  • Security
    • The topic="" parameter to the view script now respects the {AllowRedirectUrl} configure flag so you can disable redirecting to URLs which could be abused for phishing attacks.
    • More robust authentication denial when redirected after failed authentication (follow up from TWiki:Codev.SecurityAlert-CVE-2006-6071.)
    • More robust TablePlugin, guarding against a sort with very high non-existing column numbers, which may result in a high server load.

  • User Interface
    • Left Bar should not show logout when using ApacheLogin because you cannot in reality log out.
    • Can't de-select all options in a checkbox.
    • Duplicate values in checkbox and select when creating a new topic.
    • Form initialization with defaults not working.
    • Multiselect for forms does not work.
    • Size of attachment should only be shown for the most recent version.
    • JSCalendarContrib only works with IE in PatternSkin.

  • API, Skins and Templates
    • The print view handled is updated to allow custom templates that can be printed. Note that the viewprint template is subject to additional changes in next releases.
    • The Kupu WYSIWYG editor has been split out of WysiwygPlugin into KupuContrib to allow other editors to be integrated with TWiki.

  • Printing
    • Verbatim Text not completly printing with IE6.0.
    • Printable loses URL parameters.
    • Printing in Firefox truncates tables.

  • Miscellaneous Bug Fixes
    • Don't include anything when trying to include a non existing section.
    • Turn off {AutoAttachPubFiles} in default distribution.
    • The edit url parameters are not properly passed through change form screen and checkpoint save.
    • Formfield not correctly rendered when type is textarea.
    • IF cannot check for existence of INCLUDE parameter.
    • Firefox downloads attachments as the topic name and not the real file name.
    • Edit and FormattedSearch expands $nop, $quot, $percnt, $dollar in $formfield()
    • Scripts hang in TWiki::UI:run at drain STDIN logic (this is now configurable - whether you need it depends on OS and webserver.)
    • Non-graceful error handling on mail issue during registration.
    • Include of external doc set wrong url in relative links.
    • In INCLUDE, warn parameter does not work when including a URL.
    • WEBMANAGE permission no longer required (removed.)
    • Context not authenticated despite Apache Require valid-user Login.
    • INCLUDE of URL on subdomain returns wrong pages.
