View source for Mediawiki references and how tos

- 2017-07-26 Wednesday -


Ted having trouble restoring a Mediawiki 1.19.2 database dump to a back-up server, where Mediawiki 1.28.0 version is installed.  Not sure whether updating the database schema on the newer versioned back-up server will work.  Here is a Mediawiki reference to an update script which is part of this open source wiki project:


   *  https://www.mediawiki.org/wiki/Manual:Update.php


Detailed version information of Mediawiki installations and supporting software elements, on original and back-up servers:

{| class="wikitable"
|-
| Product || alta-ubuntu version || alta-spare-2u version
|-
| [https://www.mediawiki.org/ MediaWiki] || 1.19.2 || 1.28.0
|-
| PHP || 5.3.5-1ubuntu7.11 (apache2handler) || 7.0.18-0ubuntu0.16.04.1 (apache2handler)
|-
| MySQL || 5.1.54-1ubuntu4 || 5.7.13-0ubuntu0.16.04.2
|}


So there are differences between Mediawiki 1.19.2 and 1.28.0 in the names of wiki database table fields, which led to the restored wiki on host alta-spare-2u not being able to present any wiki pages.  The brief error message indicated, however, that setting two Mediawiki variables in the Mediawiki configuration file LocalSettings.php would produce on next visit to wiki page a more detailed debugging report.  This more detailed debugging report mentions the possible need and help of running <code>updatedb.php</code>.
