Maintenance

Re-Initializing the Database

If your FlowchartWiki Database is corrupted, you may re-generate the table that contains the links between the pages by running the fchw\_RefreshPages.php script from the commandline.

cd to directory htdocs/<yourWiki>

php ./extensions/flowchartwiki/maintenance/fchw_RefreshPages.php

Windows Note:

PHP could be started by

c:\Program Files\Apache2\modules\php\php.exe

Unix Note:

You may need to have the PHP-cli package installed on your system.

Temporary Files

FlowchartWiki and PDFBook create temporary files in these directories:

./images/flowchartwiki
./images/pdfbook

FlowchartWiki Note:

• The filenames are created from a hash of the database-prefix and the name of the wikipage and are overwritten for each update.
• There are four files per page:
  • .dot source which was converted to .png and .map by graphviz.
  • .png with the graph,
  • .map with an ImageMap for HTML Display
  • .dot.md5 which contains the hash value of the dot file and is used to validate, if an image needs to be re-created.
• Deleting these files is safe, they will be recreated at the next access, but you will have to delete all 4 files per page.
• Stale files will only exist for pages that have been deleted, so a frequent purging of this directory is not required.

PDFBook Note:

• There are 2 files per .pdf document
  • .html source (no Extension) which gets converted to .pdf by htmldoc
  • .pdf with the .pdf document
• The filenames are ‘pdf-book-‘ with a random number.
• These Files are created at each creation of a .pdf Document and are not re-used.
• In Pdfbook 1.1.0 the files are deleted after they have been delivered to the user, so the directory should be mostly empty.
• you may want to configure a cron-job to clean up this directory.

Moving to new empty server

• Export all pages from old server via page Special pages - Export pages
  • First see list of categories, and load pages for each one.
  • Don’t forget to add category page like (Category:Test) and MainPage
  • Don’t forget to add customizing pages (Customizing:Configure_Chart, Customizing:Configure_Chart_Documentation, Customizing:Configure_EPK)
• New server - choose Special pages / Import pages and select exported file
• Copy your logo to images/logo.png and this line to Localsettings.php

$wgLogo = "/wiki/images/logo.png";

• Copy Mediawiki:Sidebar page to new location
