Hi devs,
I'm wondering why we haven't moved to using XQL instead of HQL.
Any reason?
If not, I'd like to suggest we start using it everywhere we currently use HQL since
XWQL since is much nicer. Also since we don't use it our users don't use it.
Additionally I'd like to propose that we move to a ScriptService to access the query
manager.
From Velocity you'd write the following to get a Query:
$services.query.xwql("....")
Note that the ScriptService implementation would replace the SecureQueryManager
implementation.
We would also deprecate XWiki.getQueryManager.
WDYT?
Thanks

Is it secure?
The searchDocuments function has the benefit of having had a lot of security review.

I don't feel that's a good enough reason not to use it since it would mean that we
would never use any new API. If we want to use it, we can review it from a security POV.
That said, it looks secure, see
http://svn.xwiki.org/svnroot/xwiki/platform/core/trunk/xwiki-query/manager/…
The searchDocuments function has the benefit of having
had a lot of security review.
Well the Query Manager has had the benefit of being written after searchDocument, thus
inheriting from best practices.
Thanks

I think the major issue is that nobody knows it very well and without
Artem to push on it and help we just forgot about it.
Also I think Artem was waiting JCR2 that was not release when he
started working on it to finish XQL implementation that was too
limited by JCR1.
But yes we should really use XQL if possible.
Thanks

Why do you think it's not finished? from what I've seen it looks finished and it
worked well when I used it.
I only saw a potential grammar issue that you are forces to use "as" for a query
to be valid. For example:
"from doc.object(XWiki.XWikiUsers) as user"
(using "from doc.object(XWiki.XWikiUsers)" will not work)

Yes that's another question: IMO we should move the query plugin outside of the core
into the sandbox since I don't see a usage for it right now and xpath support should
be added to the query module.
Is anyone using it?

We need to get this more used. It's highly important for future
portability, and the queries are much nicer.

I've used it a little recently when writting applications, and indeed it's way
nicer than our HQL way or querying.
Starting to use it inside XE will help us spot potential bugs and limitations.
+1 for the script service as well.

Done for the script service + documented at
http://platform.xwiki.org/xwiki/bin/view/DevGuide/QueryGuide
Feedback welcome before the XE 2.4 final release if you want to change something.
