[MediaWiki-l] More Lua stuff not working

Hey John

This is no problem originating from your setup. Scribunto on itself together with your lua installation seems to work as intended. Your wiki parses and interprets your Modules correctly up to the point, where it runs into a script error:
Your Module:Effective_protection_expiry calls a parser function named PROTECTIONEXPIRY which is a magic word introduced in MW 1.27. Since you are running 1.25.1 this is not present in your system, therefor lua issues a runtime error. Again: that is to be expected. You installed and configured Scribunto correctly, now you have to get your modules working. This, however, can be tedious. I speak from experience... :/

Regards,
Tobias Oetterer

Betreff: [MediaWiki-l] More Lua stuff not working

OK, So i'm trying again to get Lua to work on my server., Specs; ubuntu linux; Apache, mysql, mediawiki 1.25.1, lua 5.0 5.1 5.2 all installed from ubuntu; Scribunto versions of binaries are sketchy and have consistently failed to work properly. Lua is executable from the command line so I am certain there are no issues there. In the snip from local settings below, the 'lua' is a symbolic link to lua5.2 as set up by my distro manager.

I have extension Scribunto installed and configured thusly in LocalSettings

require_once( "$IP/extensions/Scribunto/Scribunto.php" ); $wgScribuntoEngineConf['lua']['luaPath'] = ( '/usr/bin/lua' ); $wgShowExceptionDetails = true; $wgScribuntoUseGeSHi = true; $wgScribuntoUseCodeEditor = true;

Now this is the error message I'm getting. I have googled it and there seem to be a crap load of sites with this issue.

Lua error: callParserFunction: function "PROTECTIONEXPIRY" was not found.

Backtrace:

   1. *(tail call)*: ?

I have virtually no idea how to fix this. I do have all the required modules installed also.
Thanks in advance for any tips.
John
