Re: enhancements/fixes for slide 2.1

Hi Max and Slide list...

I was wondering if your fixes to the DASL ordering and limiting have  
been added to Slide yet?
I'm working with a 6 months old Slide build or so and ordering seems  
to be broken although limiting works.

Ordering by getlastmodified e.g. in this DASL search does not order  
the results:

<D:searchrequest xmlns:D='DAV:' xmlns:S='http://jakarta.apache.org/ 
slide/'>
<D:basicsearch>
<D:select><D:prop><D:getcontentlength/><D:creationdate/ 
><D:displayname/><D:getlastmodified/></D:prop></D:select>
<D:from><D:scope><D:href>files</D:href><D:depth>infinity</D:depth></ 
D:scope></D:from>
<D:where>
<D:and>
<D:or>
<D:contains>***</D:contains>
<S:property-contains><D:prop><D:displayname/></D:prop><D:literal>***</ 
D:literal>
</S:property-contains><S:property-contains>
<D:prop><D:creator-displayname/></D:prop><D:literal>***</D:literal>
</S:property-contains>
<S:property-contains><D:prop><D:comment/></D:prop><D:literal>***</ 
D:literal></S:property-contains>
</D:or>
<D:not-is-collection/>
</D:and>
</D:where>
<D:orderby><D:order><D:prop><D:getlastmodified/></ 
D:prop><D:descending/></D:order></D:orderby>
</D:basicsearch></D:searchrequest>

Hi Hippo!

Hippo is just my employer ;) Just call me Max.

Fromm y point of view it would be great if you would become a slide
committer and could add patches to the sources directly. If you are
interested, I would start a voting thread on this mailing list.

That would be great! I would be very honored.

I think most of your patches are very helpful for the slide
community.

Thanks, I do my best.

One comment to your patches regarding the lucene-based search:
If you use lucene directly to limit the results this might
cause some
trouble if you are using acl's. The acl's get evaluated after slide
retrieves the search result from lucene. If you for example
specify a limit
of 10 results and the user executing the DASL-request has no
permissions to
read half of them, he would only get 5 files even if he
specified to get 10.
So it would be very helpful to have a configurable switch to
select if you
want to have a fast system (with the risk of wrong number of
results) or a
slower search with correct results.

Actually, you cannot tell Lucene to only return so many hits.
The nice thing about Lucene's Hits datastructure is that it
lazy-loads data from the index. That way, it can return the
full structure, without much of the overhead, and you can
decide how many you access yourself. What I do is to iterate
through the Hits until I generated as many authorized results
as needed. What makes it fast is that sorting is done in
Lucene as well, so even then, you don't have to load all
results in memory and sort them there as it's done right now.

Why have you used JMS to notify cocoon? Have you had a look at the
Notification abilities in the slide webdavlib?

I wasn't aware that the webdavlib had such a feature. Also,
when I joined the team here, JMS notification was already  
implemented.

Bye!
max
