Description OverlordQ 2008-03-19 09:15:51 UTC
I got this error message once when browsing the wiki normally, a refresh of the page didn't show the error message again so I thought it was just some caching error since I just updated from svn.  However somebody in #mediawiki was asking about schema changes and I came across r32085 so I tried running the maintnence script, and sure enough, there was that error message again:

===
Warning: pg_query(): Query failed: ERROR:  current transaction is aborted, commands ignored until end of transaction block in /home/wiki/includes/DatabasePostgres.php on line 553
A database error has occurred
Query: SELECT  COUNT(*) AS pages,COUNT(IF(page_namespace=14,1,NULL)) AS subcats,COUNT(IF(page_namespace=6,1,NULL)) AS files  FROM categorylinks,page  WHERE cl_to = 'Rainbow_Tables' AND (page_id = cl_from)
Function: Category::refreshCounts
Error: 1 ERROR:  current transaction is aborted, commands ignored until end of transaction block

Backtrace:

If I try running that through something like phppgadmin you get a more helpful error message:

====
ERROR:  function if(boolean, integer, unknown) does not exist
LINE 1: SELECT  COUNT(*) AS pages,COUNT(IF(page_namespace=14,1,NULL)...
                                        ^
HINT:  No function matches the given name and argument types. You might need to add explicit type casts.

In statement:

SELECT  COUNT(*) AS pages,COUNT(IF(page_namespace=14,1,NULL)) AS subcats,COUNT(IF(page_namespace=6,1,NULL)) AS files  FROM mediawiki.categorylinks,mediawiki.page  WHERE cl_to = 'Rainbow_Tables' AND (page_id = cl_from)
====

for PG that should be something like:

====
SELECT  COUNT(*) AS pages,COUNT(CASE WHEN page_namespace=14 THEN 1 ELSE NULL END) AS subcats,COUNT(CASE WHEN page_namespace=6 THEN 1 ELSE NULL END) AS files  FROM categorylinks,page  WHERE cl_to = 'Rainbow_Tables' AND (page_id = cl_from)
====

Problem is on line 278 of trunk/phase3/includes/Category.php
Comment 1 Greg Sabino Mullane 2008-03-19 13:15:53 UTC
Should be fixed now, as of r32173. You will need to run maintenance/update.php to add the new category table first.
