This thread from TV Tropes is proof positive no one there has a clue what the hell they are talking about concerning their own site software.
Apparently, they really need a script to migrate pages from one namespace to another, which basically means moving a bunch of pages from corner of the wiki to another, and according to Fighteer (who supposedly knows computer programming), this cannot be done at this point, and some other certified idiot says batch scripts can crap out the server.
As for Fighteer, thanks for proving you are incompetent I took you for, as Brent Laabs wrote a Perl script to do the dump of TV Tropes you had the gall to call a DDoS attack, and has written several more (in conjunction with the MediaWiki::Bot Perl script) to do things like namespace migration, and was doing most of this by hand even before he found that MediaWiki::Bot script for All The Tropes, so WOW, thanks for proving you know nothing about coding despite your supposed job.
Also, PmWiki is written in PHP, and you can write all sorts of scripts in PmWiki, including batch scripts with server limits to avoid timeouts or server crashes, so as for the other idiot in that thread, please stop, you're embarassing yourself with your coding fail. Yes, a fool can write a badly done or limitless script, but a halfway competent programmer can insert failsafes against that.
MediaWiki already has lots of scripts for similar purposes, and writing one in PHP for PmWiki should be trivial for Fast Eddie, or I would think, given what he has coded up to this point.
I'll be the first to admit I'm not a very good coder myself and would need a crib sheet to write my own code, but I do know the basics of how to write good code, so the sheer ignorance in the above link had me laughing uncontrollably, which I suppose is one possibly entertaining thing I've derived from TV Tropes of late.
