Hi, i tried to return http-status 404, but my service returns status 400: This is the code in my XQuery: fn:error(xs:QName('error'), 'Invoice ' || $id || ' does not exist', 404) This is what curl prints: * Trying 127.0.0.1... * Connected to localhost (127.0.0.1) port 8984 (#0) > GET /softwareberatung/revenues/2015/15-123 HTTP/1.1 > Host: localhost:8984 > User-Agent: curl/7.47.0 > Accept: */* > < HTTP/1.1 400 Bad Request < Set-Cookie: JSESSIONID=cfedc7x61od51p8o40uxm8dfe;Path=/ < Expires: Thu, 01 Jan 1970 00:00:00 GMT < Content-Type: text/plain;charset=UTF-8 < Content-Length: 97 < Server: Jetty(8.1.18.v20150929) < Stopped at /home/christoph/basex/restxq/Revenue.xqm, 64/19: * Connection #0 to host localhost left intact [error] Invoice 15-123 does not exist Regards Christoph Gaukel

Hi, In a file with a structure like <l> <d> <f>a</f> <f>b</f> <f>c</f> </d> <d> <f>a</f> <f>b</f> <f>c</f> </d> </l> If I type doc($b)//f[1]/following::f the processor gets out of main memory, even though the file is about 2.2MB and the structure is simply the one showed above (many sibling d elements) Any idea why? Thanks Joseph

[DBA] jobs-users/server-sessions
by Fabrice ETANCHAUD 03 Mar '17

03 Mar '17

Dear all @BaseX, Could you please explain the exact meaning of the server sessions table in the dba jobs-users window ? I expected to find a list of (servlet) sessions, but instead one can see all the session variables (and among them the session ids). Is it expected behavior ? In that case what does it mean to 'kill' a session variable ? Thank you for showing session ids in the log ! Best regards, Fabrice Etanchaud Groupe FBO

Re: [basex-talk] basexhttpstop hangs in 8.6.1

Hi Tim, The problem has been fixed with the latest snapshot (thanks to Marco for providing me with more details). Have fun everyone, Christian Am 28.02.2017 1:04 nachm. schrieb "Tim Thompson" <timathom(a)gmail.com>: I've also noticed similar behavior in version 8.6 on Ubuntu 14.04. If I start the server in one terminal window and then run the stop script in a separate window, the server does stop, but the basexhttpstop script keeps hanging. -- Tim A.

[REST-XQ] cookies and path cookie
by Fabrice ETANCHAUD 02 Mar '17

02 Mar '17

Dear all (again ;)) As BaseX as a Web Application can serve several 'sub' applications, I ran into the following issue : 1- Logged in into the DBA interface 2- Session:close() in another rest-xq end point (in the same browser) 3- I got disconnected from the DBA interface It seems normal behavior because cookie is shared among all basex applications in the same Web Application (path cookie is the same for all sub applications). I cannot figure out how we could easily have private cookies for each 'sub-application' ? Best regards, Fabrice Etanchaud

basexhttpstop hangs in 8.6.1
by Marco Lettere 02 Mar '17

02 Mar '17

Hello all, I just downloaded Basex861.zip for Linux (Ubuntu 16.04 the host). Unizipped and started basexhttp. Everything ok. In another shell I launch basexhttpstop which correctly shuts down the server started before. But basexhttpstop itself does not terminate. This is causing some headache in our scripts that launch and stop several instances. Any clue? Thanks a lot, Marco.

We have about 40 databases in out project, but when trying to save files to one of them, users sometimes get this error. We're saving through webdav, on a network connection. We're on version 8.2.3 and cannot upgrade right now. Any clue would be useful. -- France Baril Architecte documentaire / Documentation architect france.baril(a)architextus.com

Integrating IntelliJ IDEA and BaseX
by Bridger Dyson-Smith 01 Mar '17

01 Mar '17

Hi all, I'm hoping to get some feedback (and potential collaborators) on a wiki page I created[1] that attempts to help a user get started with IDEA, XQuery, and BaseX. However!, I'm feeling a bit uncertain about my limited experience with workflows, tooling, and IDEA set up, and so I'm hoping that those of you on this list who use BaseX and IDEA might be willing to pass along feedback about the linked documentation. Particularly, how are you interacting with BaseX both as a processor and as client/server? How are you starting and stopping your server? What pieces of IDEA are you leveraging to make working with XQuery and BaseX a(n even) better experience? Thank you in advance for your time and trouble. Best, Bridger [1] http://docs.basex.org/wiki/Integrating_IntelliJ_IDEA

querying xml with namespaces.
by Witold E Wolski 01 Mar '17

01 Mar '17

Apologies if I am hard to understand but I am new to the XML querying. I would like to query an XML with namespaces. As I did learn, you can do it in BaseX by including an *: in your path, e.g., db:open("myrimatchSubset","20160312_17_B3_myrimatch_2_2_140.xml")/*:MzIdentML/*:SequenceCollection/*:Peptide But I would like to be more specific than *. I did search the schema for the XML and all I found related to the search term namespace is not brief name, but: targetNamespace="http://psidev.info/psi/pi/mzIdentML/1.1" I did also found the following entry on stack overflow: http://stackoverflow.com/questions/5239685/xml-namespace-breaking-my-xpath And If I interpret the answer there correctly somehow one can register his own acronym for a namespace? Is this correct? So I am wondering if I could do the same somehow in BaseX? Alternatively, I am wondering if I could tell BaseX to disable namespace checking? Thank you a lot -- Witold Eryk Wolski

A suggestion (csv:doc, ...)
by Hans-Juergen Rennau 28 Feb '17

28 Feb '17

Dear BaseX team, if you are interested in further boosting the power of BaseX as a resource monitoring tool, you might consider the tiny, yet useful extension described below. Currently we have various functions for parsing non-XML formats into node trees: json:parse($text ...) csv:parse($text ...) html:parse($text ,,, These functions expect as input the text to be parsed, not the URI from which to retrieve the text. Of course, it is trivial to combine retrieval and parsing, using fn:unparsed-text(), like so: unparsed-text('foo.json') ! json:parse(.) However, the resulting document does not have a document URI, and it would be cumbersome to associate it with one. So how about adding three functions json:doc($uri ...) csv:doc($uri ...) html:doc($uri ...) Two advantages: first the document URI is available, second - sheer elegance. As an example of this elegance, consider the task to create a list of all .csv files found in a directory tree which have inconsistent record lengths. Using csv:doc, the solution is a simple expression, rather than a program: file:list($dir, true(), "*.csv") ! concat($dir, '/', .) ! csv:doc(.) [1 eq count(//record/count(*) => distinct-values())] / document-uri(.) Cheers,Hans-Jürgen
