[Exist-development] Compiling XQueries?

[Andrzej J. T. <an...@ch...>]

I know that internally, we compile XQueries and then cache them, prior to execution.

How difficult/involved would it be to expose the compile process, so that I could compile XQueries
ahead of time (say using an appropriate Ant task), and store/execute the pre-compiled XQueries
in/from the DB?

Thanks!

Re: [Exist-development] [Exist-open] [ exist-Bugs-3175050 ] Cannot map root URI (/) to an arbitrary folder

[José M. F. G. <jm...@us...>]

Well, I think it depends on Sourceforge linkage of internal and OpenId accounts. I usually login using an OpenId from myid.net, and my internal sourceforge user name is shown on my bug reports instead of the OpenId.

Or perhaps it is something inside SourceForge related to OpenId 1.0 vs OpenId 2.0, who knows.

Not sure if others here subscribe to the eXist bug tracker on SF, but
I've noticed that it does a pretty bad job of handling bugs submitted
by OpenID users -- see the "Submitted By" line below.  Surely OpenID
servers provide a valid username that SF isn't making use of.  I
wonder if SF itself has a bug tracker for these kinds of things?

The javadoc basically provides al information you need; Please try to read and understand this formal documentation.

to help you a bit: the Collection interface has a method with the name "createResource" ; this method provides all functionality you need for the document. The CollectionManagementService provides the functionality for managing...... collections.

Again, please study the javadoc first, these are the basics. Further more, please study the sample code in samples/src/org/exist/examples/xmldb/.

To finish: the exist-development list is meant for developers who work on the exist-db core; for your questions, please post them on the exist-open mailinglist.

Sounds like you're working in java, and I can't help you with that,
but the following XQuery code does the trick:

xquery version "1.0";
xmldb:login('/db/', 'admin', 'password'),
xmldb:create-collection('/db/', 'a/b/c')

=> creates the collection tree /db/a/b/c.  You don't have to create a
before b (and b before c etc.).

For more on the xmldb:create-collection() function, see
http://demo.exist-db.org/exist/functions/xmldb/create-collection.

My only other thought is that perhaps you weren't authenticated as a
DBA?  If you're still having trouble, please be more specific about
the error you were getting.

Please can you be more explicit? What is "child" for you, a document or a collection?

The example is based  on the xml:db api, this project has javadoc online: http://xmldb-org.sourceforge.net/xapi/api/ please check the usage of the "Collection" object

[Exist-development] Developer's teleconference

[Wolfgang M. <wol...@ex...>]

There will be another eXist developer's teleconference on Friday, 4pm
UTC time. We think those small online meetings are a good chance to
discuss ongoing developments and coordinate projects. The
teleconference is basically open to everyone who wants to contribute
to eXist, developer or not. The agenda will change depending on
attendants and interests, but the main topic for this week should be
the 1.4.1 release: What issues are still open and need to be taken
care of? Are there any show stoppers? Which trunk features are still
to be ported back to 1.4.1? Another topic is the XQuery debugger.

For the time being, we'll use skype. To participate, send your contact
details to either me (skype id: wolfgangmm) and/or Dannes (dizzzz_nl).
As an experiment, meeting minutes will be written live into the IRC
channel (#ex...@fr...).

The reserved characters shall however never be arbitrarly encoded and

As I've said, eXist's behaviour is inconsistent in this area. When I 
started to work on XmldbURI, some users were reluctant to change their 
file names... hence the % encoding.

I should have been more strict then IMHO :-)

p.b.

Re: [Exist-development] XmldbURI

[Evgeny G. <gaz...@gm...>]

Specs:
http://www.w3.org/Addressing/URL/url-spec.html#z57

Both URI are valid.

Problem: when eXist try to open a doc, it split URI to two path: collection
URI and relative doc URI
so URI like "/aaa/foo:bar.xml" will be converted to "/db/aaa/foo:bar.xml"
and then splited for parts:
"/db/aaa" - collection URI and "foo:bar.xml" - relative URI (lastSegment) of
doc in collection "/db/aaa".
Both parts eXist interpret as XmldbURI. In result we have exception, becouse
foo:bar.xml have
right xmldb scheme.

P.S. Question in subject is not "valid or invalid" URI, but eXist's
behavior.

I don't follow you..... Please study the URI / and URL specification
carefully. The specification is clear enough.

- xmldb:exist:///foo is a valid url, in /// teh hostname is missing,
referring to something local
- /db/xmldb:exist:///foo/bar is invalid, due to the :

you clearly found an issue, but I think you want to fix it in the wrong way.

Another question what is principal difference between
"/db/xmldb:exist:///foo/bar"
and "/db/aaa:bbb:///foo/bar"?

and code: doc(""/db/xmldb:exist:///foo/bar"") is working as well without any
exception
becouse relative document's URI ("xmldb:exist:///foo/bar"") has valid scheme
for XmldbURI!

P.S. The doc(""/db/xmldb:exist:///foo/bar"") returns empty. I haven't so doc

Neither Saxon or Java.net pretend to mimic a file system. Document 
"path" is an unknown concept in their definition of collection.

Obviously as other non askii chars. As I see we can use both names encoded
and not encoded,
becouse name will be decoded before this code (for doc() or other xquery
function).

Just like I said, it shouldn't.

IMHO, it's just a bad solution. How would you handle document names in 
the XQuery ? Sometimes, they would be (internally) encoded, sometimes 
not. I think, this results in something which isn't strong enough...

I think it shouldn't.
