TWiki Upgrade Notes

If you are coming from a version earlier than the 01 Dec 2000 production release, please see TWikiUpgradeTo01Dec2000 first.

The 01 Sep 2001 release has these changes that affect the upgrade of the 01 Dec 2000 version:

These are the steps you need to perform to upgrade the 01 Dec 2000 version to the 01 Sep 2001 release: [ We assume export TWIKIROOT=/some/dir/ ]

Backup all existing TWiki directories ( bin, pub, data, templates )

Unpack the zip file into some working directory:
mkdir -p ~/tmp/
cd ~/tmp
unzip ~/TWiki20001201.zip

Upgrade the TWiki document files ( twiki )
- Move the document files to your TWiki root, i.e.
  mv ~/tmp/TWiki*.html $TWIKIROOT
  mv ~/tmp/readme.txt $TWIKIROOT

Upgrade cgi-bin scripts ( twiki/bin )
- Rename your original twiki/bin directory, i.e.
  mv $TWIKIROOT/bin $TWIKIROOT/bin.old
- Move the new scripts to your original twiki/bin location, i.e.
  mv ~/tmp/bin $TWIKIROOT/bin
- Merge the changes in your current wikicfg.pm into the new wikicfg.pm. We suggest using diff -c to compare the two files if you have made heavy changes to the file, i.e.
  diff -c $TWIKIROOT/bin.old/wikicfg.pm $TWIKIROOT/bin/wikicfg.pm | less
- Restore any additional scripts you might have from the old directory, i.e.
  mv $TWIKIROOT/bin.old/somescript $TWIKIROOT/bin/
  (Note that the changes script is obsolete.)
- In case you have basic authentication:
  - The TWikiRegistration topic moved from the TWiki.Main web to the TWiki.TWiki web. Change .htaccess to reflect the new location, i.e.
    ErrorDocument 401 /cgi-bin/view/TWiki/TWikiRegistration
- Pay attention to the file and directory permissions (security issue)
- Test your TWiki installation if you can view topics. (Ignore the %HTTP_EQUIV_ON_VIEW% you see on top of the topic; this will disappear after upgrading the template files.

Upgrade template files ( twiki/templates )
- Rename your original twiki/templates directory, i.e.
  mv $TWIKIROOT/templates $TWIKIROOT/templates.old
- Move the new templates to your original twiki/templates location, i.e.
  mv ~/tmp/templates $TWIKIROOT/templates
- Merge the changes in your current template files into the new template files. To compare two files use
  diff -c $TWIKIROOT/templates.old/view.tmpl $TWIKIROOT/templates/view.tmpl | less
- Restore any additional template subdirectories of your TWiki webs you might have and merge the changes.
- Test your TWiki installation if you can view topics.

Upgrade public files ( twiki/pub )
- Move the new twiki/pub/TWiki directory to your installation, i.e.
  mv ~/tmp/pub/TWiki $TWIKIROOT/pub/
- Pay attention to the file permissions of the TWiki directory and its subdirectory and files. The files must be writable by the cgi-scripts (usually user "nobody")
- Move the new twiki/pub/twikilogo* image files to your installation, i.e.
  mv ~/tmp/pub/twikilogo* $TWIKIROOT/pub/

Upgrade data files ( twiki/data )
- Move the new twiki/data/TWiki directory to your installation, i.e.
  mv ~/tmp/data/TWiki $TWIKIROOT/data/
  Pay attention to the file permissions of the TWiki directory and its files. The files must be writable by the cgi-scripts (usually user "nobody")
- Optionally move the new twiki/data/Test directory to your installation, i.e.
  mv ~/tmp/data/Test $TWIKIROOT/data/
  (Pay attention to the file permissions)
- Move these new TWiki.Main web topics to your TWiki.Main web: TWikiGroups, TWikiAdminGroup, and if needed also OfficeLocations , i.e.
  mv ~/tmp/data/Main/TWikiGroups.* $TWIKIROOT/data/Main
  (Pay attention to the file permissions)
- The following topics in the TWiki.Main web are obsolete and can be deleted: BillClinton, GoodStyle, RegularExpression, TextFormattingFAQ, TextFormattingRules, TWikiAdministration, TWikiCategoryTable, TWikiEnhancementRequests, TWikiImplementationNotes, TWikiInstallationNotes, TWikiNotificationOfChanges, TWikiPlannedFeatures, TWikiUpgradeTo01May2000, TWikiUsernameVsLoginUsername, TWikiWeb, WelcomeGuest, WelcomeVisitor, WikiName, WikiNotation, WikiTopic, WikiWikiClones. Sample delete command:
  rm -f $TWIKIROOT/data/Main/BillClinton.*
- The following topics are new and most be copied to all of your TWiki webs: WebChanges, WebIndex.
  cp -p $TWIKIROOT/data/TWiki/WebChanges.txt* $TWIKIROOT/data/Main
  cp -p $TWIKIROOT/data/TWiki/WebIndex.txt* $TWIKIROOT/data/Main
  Repeat this for all your webs. Pay attention to the file permissions.
- TWikiRegistration moved from TWiki.Main to TWiki.TWiki. In case you customized TWikiRegistration , merge your changes back into TWiki.TWikiRegistration , then delete $TWIKIROOT/data/Main/TWikiRegistration*.
- TWikiPreferences moved from TWiki.Main to TWiki.TWiki. Merge your changes to TWikiPreferences into TWiki.TWikiPreferences.
- Modify the WebPreferences topics in all your webs to reflect the following:
  - WEBTOPICLIST should use WebChanges for "Changes", and WebIndex for "Index", i.e.
    | <a href="WebChanges">Changes</a>
    | <a href="WebIndex">Index</a>
  - In case you want to exclude a web from a web="all" search: Set this new preference
    Set NOSEARCHALL = on
- The WebSearch topic has considerable changes. Copy the one from TWiki.TWiki into all webs, or merge them if you made changes. To copy, do an edit-copy-edit-paste operation.
- Change the WebHome topics in all your webs to reflect these changes:
  1. The "Changes" link should point to WebChanges.
  2. The "Topic index" link should point to WebIndex.
  3. Change the include of the web table to %INCLUDE{"%TWIKIWEB%.TWikiWebsTable"}%
- Merge your TWikiWebsTable topic in TWiki.Main with the TWikiWebsTable topic in TWiki.TWiki. Note the new variable to query the color of a web. Delete the old TWikiWebsTable topic in TWiki.Main after merge is complete.
- The following topics in the TWiki.Main web are deprecated (because they moved to TWiki.TWiki), but still need to be present in TWiki.Main because of existing links to them: FileAttachment, TWikiDocumentation, TWikiHistory, TWikiPreferences, TWikiVariables.
  It is recommended that you edit these topics in TWiki.Main and replace the content with this line:
  This topic moved to %TWIKIWEB%.%TOPIC% in the %WIKITOOLNAME%.%TWIKIWEB% web.
- In all your webs, change references to topics that moved to the TWiki.TWiki web:
  - Change topics: TWikiUsers , WebNotify , WebHome
  - With links to: TWikiPreferences , TWikiVariables , TWikiUsers , TWikiWebsTable and WelcomeGuest

TWiki Access Control
- Read TWikiAccessControl, in case you want to use the new authorization feature based on groups.
