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).

May be with java ? > When I try to execute the query from basexclient, I'have a immediate answer but a very very very slow display : lines are displayed in blocks of one or two screen terminals... There is a problem with the data exchange between the daemon and the client I think...

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

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() allow for recursion into a directory structure like this with the /?select syntax options or should I use a combination of functions from the File Module to move through these directories? Note: I'm not pulling these files into a database, rather I'm just using BaseX as a query processor. Thanks for your time. Best, Bridger

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?

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/.basex: writing new configuration file. [main] INFO org.eclipse.jetty.server.Server - jetty-8.1.17.v20150415 [main] INFO org.eclipse.jetty.webapp.StandardDescriptorProcessor - NO JSP Support for /, did not find org.apache.jasper.servlet.JspServlet BaseX 8.3 [Server] Server was started (port: 1984). [main] INFO org.eclipse.jetty.server.AbstractConnector - Started SelectChannelConnector@0.0.0.0:8984 HTTP Server was started (port: 8984). I verified that with the same .basex file running 8.3 under OS X the options are recognized and set as expected. What would cause this difference in behavior? Here is the .basex file in the /home/basex directory when the server starts: USER = admin PASSWORD = admin DEBUG = false DBPATH = /home/basex/basex/data REPOPATH = /home/basex/basex/repo LANG = English LANGKEYS = false GLOBALLOCK = false # Client/Server Architecture HOST = localhost PORT = 1984 SERVERPORT = 1984 SERVERHOST = PROXYHOST = PROXYPORT = 0 NONPROXYHOSTS = IGNORECERT = false TIMEOUT = 30 KEEPALIVE = 600 PARALLEL = 8 LOG = true LOGMSGMAXLEN = 1000 # HTTP Services WEBPATH = /home/basex/basex/webapp RESTPATH = RESTXQPATH = CACHERESTXQ = false HTTPLOCAL = false STOPPORT = 8985 AUTHMETHOD = Basic # Local options CATFILE = /opt/dita-ot/DITA-OT/catalog-dita.xml DTD = true SKIPCORRUPT = true CHOP = false -- (this is the end of the file) -- After the server starts the offending options are omitted from the rewritten .basex file. The only difference I can think of is the Java version. The container uses the OpenJDK while I have Oracle Java running in OS X: basex@611404b26b04:~$ java -version openjdk version "1.8.0_66-internal" OpenJDK Runtime Environment (build 1.8.0_66-internal-b17) OpenJDK 64-Bit Server VM (build 25.66-b17, mixed mode) basex@611404b26b04:~$ But otherwise it's exactly the same code running in both environments and the same config file.

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 session = new BaseXClient(host, port, username, password); session.execute("open " + database); session.store(path, inputStream); session.execute("close"); My code to retrieve: BaseXClient session = new BaseXClient(host, port, username, password); session.execute("open " + database); session.execute("retrieve " + path, outputStream); session.execute("close"); Thanks in advance!

Re: [basex-talk] Unrecognized Options Running Basex in Docker Container
by Eliot Kimber 29 Jan '16

29 Jan '16

Another bit of info. If I interact with the server from within the container, e.g., connect to the basex server using the basexclient, I can set and get options but they are not reflected in the DBA app: > open test-02 Database 'test-02' was not found. [I then create test-02 using the DBA Web app to prove I'm talking to the same server] > open test-02 Database 'test-02' was opened in 0.68 ms. > set chop false CHOP: false > get chop CHOP: false But if I refresh the page for test-02 in the DBA app, it still shows a check for chop. So something seems to be up with local options. I verified that I can add data to the database itself.

bitmaps/binaries of variables
by Rob Stapper 27 Jan '16

27 Jan '16

Hi, Is it somehow possible to get the bitmap/binary of a $variable or a bitmap/binary-overlay of a $variable in BaseX? Since there is no bitmap-datatype I guess it is probably not possible or straight forward but BaseX continues to surprise me (in a positive manner). So maybe? TIA for any reply, Rob Stapper

get and extract .gz files from web
by Marc van Grootel 27 Jan '16

27 Jan '16

Hi, I hoped that I could use archive module to also extract gzipped files. I need to fetch/sync large XML from a web service that has the option of getting files with gzip encoding (to be nice to the web server). First attempt was to explicitly get the gz file via the URL and then treat it like an archive binary (extracting it with the recipe from the archive module page). The entries XML I get is empty so I suppose that I cannot read .gz Second attempt was to specify Accept-Encoding = gzip which indeed delivers the XML as a binary. But I probably run into the same issue when trying to extract. Is there a way to do the extraction of .gz encoded files without having to shell out to some kind of unzipper? Cheers, --Marc
