Re: Logging patterns

I wanted to see if anyone can provide some advice on logging practices -- just general practices that seem to be working well for you all. In my scenario, I've setup a small pipeline processing mechanism where documents are passed through any number of XSLT stylesheets using transform:transform(). I typically store the results into a new collection in the database. I was wondering:
  • If using transform:transform(), where are my <xsl:message> calls going?
My guess, to console. 
  • Do I have access to eXist modules/functions in my stylesheet when using transform:transform() if I declare the namespaces?
  • Is it better to use util:log() / util:log-app()?
  • Is a custom solution using XUpdate and logging directly to the database acceptable?
No, you can't ... only eXist's xslt you will be able to give you access you 'all' eXist's features.

Apart from causing stack overflows, sequence constructors did consume
too much memory. I fixed this in trunk yesterday. There should be no
limit to the length of the sequence now.

Ok, we found the code, but no fix..... yet

Re: Antw: Versioning with Update Extensions

Fair enough, it makes sense why it is disabled in the first place.
But it would help a lot to manually trigger a versioning event.
Unfortunately, I dont know how to implement this function.
So thanks in advance for your support and your help!

Yes. The versioning trigger is not enabled for node level updates.
Creating a new revision for every small update would be overkill.

Markus is probably right that we should provide a way to manually
create a new version from an XQuery. It should be possible to
implement a simple function which does that, but I'll need to check
against the source code.

Example of data replication between two eXist servers

I would really appreciate if somebody can provide a code snippet for data 
replication between two eXist servers without using the REST interface 
(which is disabled for security reasons).

going crazy for an incredible behavior

Hi all,

 

I’m discovering a really strange behavior, and I spent all the day looking for a possible error, with no luck.

 

I got a (quite complex) piece of code, which give me an unexpected result.

 

Please, look at the following fragment, where the third line is commented:

 

                               return

                                               for $rel at $count in $relationships return (

                                                               (:if ($count ne 6) then () else :)

                                                                               let $uuid := $rel/mm:hasObject/ <at> rdf:resource

                                                                               let $el := $ont/*/rdf:Description[ <at> rdf:about eq $uuid]                                                                            

let $object :=

                                                                                              if (count($el/mm:isInstanceOf) gt 0) then

                                                                                                              element rdf:Description {

                                                                                                                             $el/ <at> *

                                                                                                                             ,$ont/*/rdf:Description[ <at> rdf:about eq $el/mm:isInstanceOf/ <at> rdf:resource]/*

                                                                                                              }

                                                                                              else

                                                                                                              $el

                                                                                              return

                                                                                                              support:getName($rel, $object,$context,false())

                                               )

 

If I run this piece of code the result is:

 

Scelta ente

Scelta ontologia

Tipi di dati di base (W3C-XML)

xs:byte

Accesso al sistema

mm:menu

gestione sistema

 

while,  uncommenting the third line, the result is:

 

menu favoriti

 

In the first run, I got seven lines (the sixth is incorrect), while in the second run I got just one line (which is correct) corresponding to the the sixth line of the commented version : WHY are the different?

 

Every suggestion is appreciated. I run dozen of tests, rebuid the indexes, reload the DB, with no luck.

 

Please help with some ideas.

 

Running 1.4.0-rev10440-20091111 on windows 7 x32 on vmware workstation

 

TIA

 

Paolo

I am pretty sure that we did actually fix this issue, quite some time ago. Sorry have to ask: please could you

I can't imagine tomcat has influence here............

Reduce eXist-db size in a production system -reg

Hi eXist users !!!

we are going to deploy a XRX style application using eXist-db as a back end XML DB. Now, we want to reduce the actual size of the eXist-db because by default it's have more options which is actually not needed for our application. So, what s the procedure to trim the eXist-db size.

PS: We are in the final stage to deploy , pls consider to give some better solution to give compact size to the user.

Sorry do you mean the application itself rather than the db?
Perhaps you could tell us what you need? Also you can run eXist-db
with ./server.sh which should produce a minimal db without access to
the file system.
