Description Netoholic 2004-12-19 08:53:31 UTC
I have a small test wiki running the latest beta, which has about 6 articles in it (and a few 
images, redirects, etc.).

When I run maintenance/RefreshLinks.php, the links tables fill up with entries, and the wiki shows 
some incorrect results.  [[Special:Wanted pages]] shows several MediaWiki: system messages at the 
top.  Almost every article's [[Special:Whatlinkshere]] shows unrelated articles/images/etc. -and 
even redirects- pointing to it.

It almost looks as though links are being searched recursively to populate the links tables. For 
example, [[A]] redirects to [[B]] which links to [[C]], so [[Special:Whatlinkshere/C]] shows a 
direct link from [[A]]>[[C]] which doesn't exist in reality.

The refreshLinks seems to be totally BROKEN: 
- it is slow because of ugly evilly written inneficient SQL request, 
which breaks both sql server and php host with those EVIL arrays ! 
crazy ! Im trying to rewrite all that stuff from scratch, but it take 
some time. 
- I suspect we also do html rendering , not only parse. 
- the code is very badly written , nearly impossible to understand, 
working on global variables in functions that hide completely the job, 
and the flow of operations. This coding style is good only for 
php-accelerators, not for human. (sorry i m hungry, because of hours 
spends in the code)

Be sure to insult our mothers, too. ;)

The new global $wgLinkHolders was not being cleared between runs; in prior versions this 
intermediate link data holding structure did not exist.
