Re: xql, Javascript and XForms

Hi,

My XForms and XQuery are in an xql page - would I just define the 
JavaScript to be the return of another XQuery and then do something like:

<script type="text/javascript language="JavaScript" src="javascript.xql"/>

?

    Cheers,

    Matthew

Using XInclude in xql

Hi,

I have some static xhtml that I want to repeat in various different 
forms (using XForms and XQuery) and I thought that XInclude is the way 
to do this neatly (instead of cutting and pasting the same xhtml 
everywhere). So in my xql, I have:

<html xmlns="http://www.w3.org/1999/xhtml" 
xmlns:xi="http://www.w3.org/2001/XInclude">
  <head>
  ...
  <body>
    <xi:include href="menubar.xml"/>
   ...

where menubar.xml is just a <div> element containing some <ul> and <li>. 
Now when I try to load this in the browser, I get:

XML Parsing Error: mismatched tag. Expected: </link>.
Location: http://localhost:8080/geneapolis/index3.xql
Line Number 1, Column 105:<html><head><title>XQueryServlet

Why isn't the use of range indexes reflected in profile log

I made a database with range indexes. Sometimes queries were slower to 
execute than I expected, making me suspect the indexes weren't used. I 
therefore included a
declare option exist:profiling "enabled=yes verbosity=5";
line in my queries, and grep'ed the profile.log* files for evidence of 
range index use, i.e, the occurrence of lines like
OPTIMIZATION Using value index to find key '...';
I almost never saw such lines in the log, and concluded my indexes 
weren't used.

It turns out the indexes were used after all. I was simply to slow to 
catch the evidence. The log files have a small default size so the lines 
reporting index used had been flushed at the time I looked for them.

Doh.

Re: Using XInclude in xql

Your code is not valid XHTML -

<link rel="stylesheet" type="text/css"
href="error.css">

has no end element as the error message suggests, so change it to either -

<link rel="stylesheet" type="text/css"
href="error.css"/>

or

<link rel="stylesheet" type="text/css"
href="error.css"></link>

Thanks Adam.

Re: Using XInclude in xql

The result of the xinclude seems to be an error message, which is not
well-formed html and contains this link element.

I have to test this out myself. We might have a general problem with
xincludes within an XQuery...

REST interface status

I'm just starting to try to test eXist. I tried loading a document using
the REST interface, as implemented in the test client httpclient.pl

It appeared to work (the document is in the database) but produced
strange output:

 ./httpclient.pl -u dhoworth -p exist -c /db/sifts -s 1agm.xml
Storing document as 1agm.xml ...
<html>
<head>
<title>Error 200 Document 1agm.xml stored.</title>
</head>
<body>
<h2>HTTP ERROR: 200</h2><pre>Document 1agm.xml stored.</pre>
<p>RequestURI=/exist/rest/db/sifts/1agm.xml</p>
<p><i><small><a href="http://jetty.mortbay.org">Powered by
Jetty://</a></small></i></p>

<blank lines snipped>

</body>
</html>

Why does eXist think that 200 is an error?

Thanks, Dave

Re: REST interface status

I think Alex mentioned this previously and there was a discussion about changing it, so perhaps Alex could shed some light on this...

well, it is a status code, not an error code (= status code with
negative side effect). maybe we should change that. from the specs in
http://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html :

10.2.1 200 OK = The request has succeeded.

10.2.2 201 Created = The request has been fulfilled and resulted in a
new resource being created.

Basically we should have a 201 here, not a 200. Adam ?

Dannes

Yeah, that's annoying.  Just something that was probably quickly
implemented and never made to have a nicer response.  It does
return a 200 status code and so it is actually a success message.

I'd like to re-factor the rest interface into components that can
be re-combined via a web.xml.  I was waiting the the 1.1 branch to be
merged before I took that on.  When I did that, I was going to
deal with issues like the above.

In the meantime, we could "fix" this.  I wonder if people have
applications that rely upon XML coming back?

Possible solutions:

1. 201 Create w/ an XML status document of

    <resource href="/exist/rest/db/sifts/lagm.xml"/>

2. 204 No content

Thoughts?

Re: REST interface status

I dont have a problem with breaking backwards compatibility until we reach version 1.0 and 1.1 final.

But then I have never really minded breaking backwards compatibility, technology should move forwards...

Thanks Adam.
