Subject: API: (bug 17027) Allow all configuration variables in $wgAPIReadableConfigVars to... 
X-Git-Tag: 1.31.0-rc.0~43392
X-Git-Url: http://git.cyclocoop.org/data/Fool?a=commitdiff_plain;h=d16183122324d9a765d694574083a7bee40d2fea;p=lhc%2Fweb%2Fwiklou.git

API: (bug 17027) Allow all configuration variables in $wgAPIReadableConfigVars to be read through meta=siteinfo&siprop=configvars. I tried my best to only make useful stuff readable and skip stuff that's sensitive (like $wgDBpassword), available already (like $wgExtraNamespaces) or useless (like $wgUpdateRowsPerJob).
