DFDL module and XSLT module
by Kristian Kankainen 13 Feb '17

13 Feb '17

Hello all. I am making a simple wrapper java module for Daffodil so that I can run DFDL parsing and unparsing from XQuery. I got communication working between BaseX and my module allready, but I can only send and return Strings. Because the module is so similar to the XSLT module of BaseX, I wonder if the java source code is available. I can't find it in the GitHub repository. Thanks Kristian K

Update facility
by meumapple 09 Feb '17

09 Feb '17

I have written a function consisting in a copy/modify expression: declare function local:mine($s) { copy $e:= $s modify (...) return $e }; It seems it is not possible to somehow make it recursive ( ... return local:mine($e) ): can anyone confirm this? What is the best way to have a recursive function while using the update facility? Best, Giuseppe

Hi all A quick update. The issue was indeed caused by our firewall. Hereby the problem is solved. Thank you for the quick response Christian!

Whatever happened to EVENTPORT? [urgent]
by Bram Vanroy 08 Feb '17

08 Feb '17

Good evening all I'm sorry to be so pushy with the urgent addendum but we have an event and some demos coming up and we only now realise that BaseX isn't working anymore. (Our own fault.) We upgraded from BaseX 7.9 to 8.3 (after going from Cent OS 6 to Cent OS 7). Thinking we could use the same settings from our .basex configuration file, I ran the command basexserver as I used to. This works, but I remember seeing a message in the command line that some attributes were not recognised and that a new configuration file was created by basex itself, and that a server was launched subsequently. The issue is, though, that we use BaseX as a back-end database system that processes requests from an apache webservice. On Machine A the webservice is running, and basex is running on machine B. The webservice fires a session request (with PHP) like so: $session = new Session("machineB", 1958, "admin", "admin"); However, the connection fails. First a warning, followed by a Fatal error. PHP Warning: socket_connect(): unable to connect [113]: No route to host in basex-client.php on line 17 Line 17 would be the first one of this clause: if(!socket_connect($this->socket, $h, $p)) { throw new Exception("Can't communicate with server."); } My instinct was that the webservice could not connect to basex because some settings in the newly created .basex file were incorrect. However, I checked them and they are definitely correct. Shown below: # General Options DEBUG = false DBPATH = /home/obelix/sonarbasex/WRPPH REPOPATH = /home/nobackup/Gretel/BaseXRepo LANG = English LANGKEYS = false GLOBALLOCK = false # Client/Server Architecture HOST = localhost PORT = 1958 SERVERPORT = 1958 USER = PASSWORD = SERVERHOST = PROXYHOST = PROXYPORT = 9591 NONPROXYHOSTS = IGNORECERT = false TIMEOUT = 30 KEEPALIVE = 600 PARALLEL = 8 LOG = true LOGMSGMAXLEN = 1000 # HTTP Services WEBPATH = /home/pricie/sonar/BaseXWeb RESTPATH = RESTXQPATH = CACHERESTXQ = false HTTPLOCAL = false STOPPORT = 8591 AUTHMETHOD = Basic I did find, however, that unlike the .basex file of our previous version, this one does not have an EVENTPORT attribute. Is this normal? I can't find it in the documentation anymore either. So if it has nothing to do with ports an access, why would I then get a 'no route to host' error? Is there ANY way that, given my basex file above, this is caused by BaseX? Or is it more likely to be a network/permission error? Thank you in advance, I'm running out of ideas! Kind regards Bram

by Braunschweig, Björn 08 Feb '17

Hey everybody, I have a basex/basexhttp:8.5.1 production container running. To access the dba web interface I created a basex/dba container and connected it to the same docker network. On the <http://host:18984/dba/login> http://host:18984/dba/login was an input box to connect to a remote BaseX server instance but with the latest basex/dba: image (8.6.1 beta) this is gone How am I now supposed to access the dba web ui ? Thanks in advance Björn

Suitability

Hi All, Because it got rejected sending this email again. [Sriram] We have an application where we need to process huge XML(300-500 XML document per day -of 15-20GB) documents need to be inserted and updated by more than 200 people. Can we use Basex for this purpose. Here is the application requirement. 1. We get 300-500 xml documents everyday 2. It should be saved in Basex server 3. Every day around 200 users would edit those document using front end application created using ASP.Net. At a time maximum 75 people edit those xml documents. I could able to insert the 3Gb of XML data in to Basex server without any issue. Which is good. I am looking for logging feature when these XML documents were edited by different users. Is this feature available in Basex Server. Is Basex is suitable for content management application? Appreciate your help this regard.

Upload XML File to Remote Basex Server with database module
by Detlef 06 Feb '17

06 Feb '17

Good Afternoon, I'm developing an interface, written in Delphi 10.1 Berlin, to a remote Basex Server, using HTTP-Server For uploading, I use the db:add query. The problem is, that I cannot upload a file, which is stored on a local path of my computer. If this file is stored on a network resource, uploading is not a problem. If I transfer the file content into a string and send this string via the above query, I got error 413 (Request entity too large) How can I solve this problem. Best regards Detlef Schmitz

Static context
by Marco Lettere 04 Feb '17

04 Feb '17

Hi BaseX community, I'm wondering whether there is the possibility to keep some kind of in-memory state among successive RestXQ invocations. I know I could use the session object but this comes at the risk of loosing the state at session expiration. I could of course use a DB but with this solution I'm not sure that paying the overhead of accessing a database is worth for the small checks I need to perform. I was thinking of using Java and create some sort of singleton but this would introduce an unnecessary dependency from a custom jar. Maybe with the Jobs module? Any other clue? Thanks, Marco.
