Hi!
Cleaning some spaces on a XWiki installation I've found a query that eats 100% CPU
and never (at least not for some 20 minutes) through results. I deleted it but, please,
could you check it to see if it contains an obvious error and, even in this case, see if
some thing could be done to avoid submitting dangerous queries?
#set($query = ", BaseObject as obj, StringProperty as prop where doc.fullName =
obj.name and obj.className='XWiki.XWikiGroups' and doc.fullName<>
'XWiki.XWikiGroupTemplate' order by doc.fullName asc")
You're adding StringProperty as prop to the query, but you put no
condition on it, so this just means that it correctly joins documents
with their associated XWikiGroups objects, but then it multiplies that
with all the possible properties that there are in the database, not
just the properties belonging to those objects.
#set($results=$xwiki.searchDocuments($query))
Running XWiki Enterprise 2.4.30451 on MySQL 5.0.26.
