Description Robert Rohde 2007-01-06 03:02:30 UTC
On the edit page a list of all transcluded templates was 
recently added.  This list is updated whenever the page is 
edited, but it fails to update when a page is purged.  This 
inability to update following a purge, means that pages 
like the Main Page of the English Wikipedia, which update 
based on a sequence of date dependent templates, will often 
have out-of-date transclusion lists.  The out of date lists 
make it more difficult to combat recent template vandalism.

The provided URL shows a test case of this bug based on a 
fictitous template tied to system time.

It's not supposed to; the data comes out of the link tables, which aren't
rebuilt upon purges. Either do a null edit or wait for the job queue to update
the template links table.

> or wait for the job queue to update the template links table

Ignore this bit, it's not applicable.
Comment 3 Robert Rohde 2007-01-06 03:09:57 UTC
So how quickly might one expect them to be rebuilt?  They have been at 
least several hours out of date that I have seen.

Comment 4 Rob Church 2007-01-06 03:22:02 UTC
As I've explained above, a null edit is required to cause a link table update.
Comment 5 Robert Rohde 2007-01-06 03:24:15 UTC
Okay, then is there some reason why a purge request shouldn't be made to 
also update the relevant portion of the link table?
Comment 6 Rob Church 2007-01-06 04:08:17 UTC
"Purge" means "purge caches" - link tables aren't a cache. I don't think it
would be a brilliant idea to cause link table updates on purges, to be honest,
given the current rate at which our users apply "purge it" as a fix-everything.
Comment 7 Robert Rohde 2007-01-06 04:39:07 UTC
You mean it doesn't fix everything?  ;-)

I had always assumed that purge was functionally equivalent to a null edit in 
terms of rebuidling the page without the bother of a log entry.  Learning that 
it is not strikes me as suprising behavior.  
Comment 8 Rob Church 2007-01-06 04:42:20 UTC
No, not at all. A purge merely touches the page record so that existing parser
caches of it will be cleared for all users.

Link tables and other "relationship" information is updated when a page is saved.
