Re: [basex-talk] Connecting database in C#
by Christian Grün 11 Feb '16

Hi Raj (cc to the list), > Yes, I did. I have created a Session class (provided online) but unable to connect it to the existing database. > // create session > Session session = new Session("localhost", 1984, "admin", "admin"); > > It doesn't find the localhost on my machine. I guess, I am missing something. Do I need to install SQL server first? BaseX is the database, so there’s no need for SQL server. Did you start a BaseX server instance?

BaseX, Zorba, e-mail module
by Tim Thompson 05 Feb '16

05 Feb '16

Hello, I would like to be able to send e-mail from a Web app I am developing in BaseX and was wondering whether anyone else had implemented this functionality (or whether a BaseX e-mail module might be in the works?). I see that Zorba has an e-mail module with support for SMTP and IMAP (not to mention many other useful modules), which leads me to wonder whether anyone has worked on a BaseX connector for Zorba. In the meantime, I decided to try using the BaseX process module to call Zorba, … [View More]

file:write and include-content-type
by James Ball 31 Jan '16

31 Jan '16

Hello, I’m getting an unexpected behaviour with the serialization option include-content-type and file:write with HTML. If I write a document without a <head> element then one doesn’t get added and nothing happens. file:write("test.htm",<html><body/></html>,map {"method":"html", "html-version":"4.0","include-content-type":"yes”}) returns: <html> <body></body> </html> Is this correct? If there is a head then the <meta> gets added … [View More]

basexhttp jetty 413 (Request Entity Too Large: head) / consecutive queries

Hi everyone, searching the basex rest-interface with a VERY long query ends in the following error-message: In Terminal basexhttp: [qtp1513712028-21] WARN org.eclipse.jetty.http.HttpParser - HttpParser Full for SCEP@5be8c98d{l(/0:0:0:0:0:0:0:1:49641)<->r(/0:0:0:0:0:0:0:1:8984),s=1,open=true,ishut=false,oshut=false,rb=false,wb=false,w=true,i=0r}-{AsyncHttpConnection@5d928144,g=HttpGenerator{s=0,h=-1,b=-1,c=-1},p=HttpParser{s=-10,l=0,c=-3},r=0} In the Browser: 413 (Request Entity Too … [View More]

Re: [basex-talk] Rép: Re: Slow XQueries on a quite small database but great number of docs
by Christian Grün 31 Jan '16

31 Jan '16

Hi Jean Marc (cc to the list), What happens if you run the query in the GUI (how long does it take)? How much time is spent if you write the client output to a file (basexclient -o output.xml)? Which client do you use? On Sun, Jan 31, 2016 at 5:41 PM, <ansel.jm(a)free.fr> wrote: > Many many thanks for your quickness ! > Yes I optimized the database (OPTIMIZE ALL).

BaseX fn:collection() questions
by Bridger Dyson-Smith 31 Jan '16

Hi all, I'm using BaseX 8.3.1 and am trying to access a directory structure like so: declare namespace t = "http://www.tei-c.org/ns/1.0"; for $ready in fn:collection("/usr/home/bridger/Documents/foo/bar/?select=*.xml;recurse=yes")/t:TEI let $title := fn:data($ready/t:teiHeader/t:fileDesc/t:titleStmt/t:title) return $title The structure under bar/ looks something like bar/ 001/ 001.xml 002/ 002.xml 003/ 003.xml ... ... 009/ 009.xml Does BaseX's fn:collection() … [View More]

tumbling window and db:add in same expression
by Hondros, Constantine (ELS-AMS) 30 Jan '16

30 Jan '16

Hello all, BaseX doesn't seem to like the query below. Any particular reason - it makes sense to me. I'm trying to add items to a DB incrementally to (attempt to) avoid running into out of memory exceptions when cutting a slice of a large DB into a smaller one. for tumbling window $w in db:open(myDB')//ani:ref-authors/ani:author start at $s when $s mod 50000 = 1 return db:add( 'sliceDB', <index>{$w}</index>, 'somepath.xml' ) Improper use? Potential bug? Your feedback … [View More]

Unrecognized Options Running Basex in Docker Container
by Eliot Kimber 29 Jan '16

29 Jan '16

I'm seeing a difference in how the .basex file is processed between running a server under OS X directly and running it in a Docker container. In particular, my local settings are being rejected as unrecognized. Here's the startup messages from within the basex container: basex@611404b26b04:~$ basexhttp /home/basex/.basex: Unknown option 'CATFILE'. /home/basex/.basex: Unknown option 'DTD'. /home/basex/.basex: Unknown option 'SKIPCORRUPT'. /home/basex/.basex: Unknown option 'CHOP'. /home/basex/… [View More]

Java client and binary files
by E. Wray Johnson 29 Jan '16

29 Jan '16

When using the sample Java client to store/retrieve binary/raw files I have to execute separate open/close commands. It is my understanding that this locks the database. In a multi-user scenario, such locking is undesirable as binary/raw files can be quite large. And since there is no alteration of the indexes etc during such operations, is there a better way? Also, why isn't there a corresponding retrieve method on the Java client, similar to the store method? My code to store: BaseXClient … [View More]
