server class trouble
by Jason Ricles 03 Apr '14

03 Apr '14

To whom it may concern, I am trying to see what stuff I can do with the server class and keep running into a org.basex.core.BaseXException: java.nio.channels.OverlappingFileLockException error. With the following code session.setOutputStream(System.out); session.execute("XQUERY doc('/home/jricles/Desktop/adsss.xml')"); session.query("doc('adsss')/*").execute(); System.out.println(); To figure out the problem and correct it through trial and error to learn how to use BaseX in java better, I am trying to use the following class from the import server.* statement I imported at the beginning of the code http://docs.basex.org/javadoc/org/basex/server/LockingTest.html. However it gives me an error that this class does not exist in the Server import. I am curious if this javadoc is out of date, or if it is incorrect in something that I might be doing in my code. Thanks, Jason Ricles

Multiple db:replace() = slower updates with 7.8
by France Baril 02 Apr '14

02 Apr '14

Hi, We run batch processes on our files in order to send them out to translation in xliff format (xml format for translations). I run a piece of code that: 1. applies transformations 2. file:writes the resulting files (for debug purposes) 3. and then db:replaces the resulting files. If I send 5 files into the process, it takes a few seconds before the files appear on the file system. Yet full process with the db:replace takes 2 minutes to complete. When I send 60 files... the process never ends. All files are available on the file system and are valid, which means I am fairly certain that the freeze doesn't occur because of an error in one of the files. There is no error message in the terminal window. Is possible that something was changed after 7.7 that would affect performance? On our production server, which is on 7.7 we can run 100+ files in just a few minutes. Maybe there are new server settings that we missed? For reference, here is the code. I understand that updates are all performed at the end of the process, which is why we get the debug files first, but the lag time between the time where we get all files on the file system and the db:replace seems huge. *declare* *updating* *function* *translation:transform-to-xliff*(*$menu-id* *as **xs:string*, *$lang* *as **xs:string**, *$package-number* *as **xs:string* ){ *let **$menu* := *menu:xml-get-menu*(*$menu-id*, 'en-us') (: Need to translate menu and its topics without getting duplicated topics twice:) (: Always send the reusable strings from writers and from dev... doesn't cost anything if no new string anyway :) *let* *$file-ids* := (*$menu-id*, *for **$id* *in **distinct-values*( *$menu*/descendant::*[*name*()='topicref']/*data*(*@id-ref*))[1] *return * *$id*, 'stringreferences', 'stringreferencestransform') *return *(*for **$file-id* *in **distinct-values*(*$file-ids*) *let* *$file* := *db:open*('en-us')/*[*@id*=*$file-id*] *let* *$skl-href* := 'skeletons/' || *$package-number* || '/'|| *substring-after*(*$file*/*base-uri*(), 'en-us/') *let* *$file-with-preserve* := *copy* *$copy* := *$file* *modify*(*if* (*exists*(*$copy*/*@xml:space*)) *then *() *else **insert* *node* *attribute* {'xml:space' }{'preserve'} *into* *$copy*) *return **$copy* *let* *$all-trans-files* := *xliff-transformer:create-translation-files*(*$file-with-preserve*, *$package-number*, *$menu-id*, *$lang*, *$skl-href*) *let* *$skeleton* := *$all-trans-files*[1] *let* *$xliffs* := *for **$xliff* *in **$all-trans-files*[ *position*() != 1] *return **$xliff* *let* *$debug* := *file:write*('Debug-xliff/skls/' || *tokenize*(*$skl-href*, '/')[*last*()], *$skeleton*) *return *(*db:replace*('Translation-management', *$skl-href*, *$skeleton*), *for **$xliff* *in **$xliffs* *let* *$target-lang* := *$xliff*/descendant::*[*name* ()='file']/*data*(*@target-language*) *let* *$lang-pack-name* := *concat*(*$target-lang*,'_', *$package-number*) *let* *$file-loc-end* := *$menu-id* || '/' || *$lang-pack-name* ||'/' || *substring-after*(*$file*/*base-uri*(), 'en-us/') (:let $debug := file:append('debug-ids.xml', '

WEBDAV bug when changing admin password in 7.8.1
by Maud Ingarao 02 Apr '14

02 Apr '14

Hi :) We are experiencing a strange bug in 7.8.1 After installing and before changing the admin password is everything ok (client connexion, rest and restxq connexions, webdav connexion...) But as soon as we change the admin password (best practice ? :p), the webdav connexion becomes impossible, and so the restxq connexion with a 404, while the rest connexion remains ok, like the client one. WEBDAV example : With the admin/admin password : mingarao@l100318:~$ cadaver http://localhost:8984/webdav Authentication required for BaseX on server `localhost': Username: admin Password: dav:/webdav/> ls Listing collection `/webdav/': succeeded. Coll: input 0 avril 1 16:49 Coll: my 0 avril 1 16:50 Coll: test 0 avril 1 16:49 dav:/webdav/> After changing the admin password mingarao@l100318:~$ cadaver http://localhost:8984/webdav Could not open collection:*-> doesn't even ask for a login/password* Impossible de s'authentifier auprès du serveur: missing realm in Basic challenge dav:/webdav/? ls The `ls' command can only be used when connected to the server. Try running `open' first (see `help open' for more details). dav:/webdav/? open http://localhost:8984/webdav Could not open collection: Impossible de s'authentifier auprès du serveur: missing realm in Basic challenge dav:/webdav/?

bug or requirement
by Rob Stapper 30 Mar '14

30 Mar '14

Hi there, In order to maintain consistency in my solution-patterns I seem to end up with the need for cyclicly chained/imported modules: module "A" imports module "B" which imports module "A". Too bad that the "import module" command of Basex can't handle this type of structure. Now I can't access the functionality of "A" within module "B". What are the chances in solving this issue?

Then I export the project to create a runnable jar th rough Eclipse. Jar file is created smoothly, but when I run the jar, GUI is not starting. NO ERROR messages.. !!! Can you put some light on this issue ? -- Have a nice day JBest

Is there any mechanism of version control of objects, kept in BaseX database?
by Moshe Zuisman 29 Mar '14

29 Mar '14

Hi. I am right now using BaseX to analyse My XML files that keep installations pseudo-code(XMLs of IzPack open source installer). Procedure is quite entangled. I keep my XML source in files.. I periodically recreate BaseX database from folder that contain all my XML files and use it to perform queries, that analyse my data. When I find something I need - I have to go back to file, and perform search there to find once more therexml element . already retrieved at BaseX query. I weight to move from files to BaseX database and keep all info there. But... Here is a catch: Files I can keep in version control system (IBM Rational Cynnergy system) Is there some way to keep versions track of data - kept in BaseX database? Some interface with standard Version control systems, or any other way?

Accessing DOCTYPE information after DB creation?
by Hondros, Constantine (ELS-AMS) 28 Mar '14

28 Mar '14

Hi all, I would really like to be able to query a large corpus of documents to get names and counts of the DTDs which are declared in the (somewhat old-fashioned now) DOCTYPE declaration: <?xml version="1.0" encoding="utf-8"?> <!DOCTYPE converted-article PUBLIC "-//ES//DTD journal article DTD version 4.5.2//EN//XML" "art452.dtd" [ ]> <converted-article>  Is there any way to get BaseX to preserve this information? Can I rewrite the doctype declaration into some sort of element node as the DB is being created so that this info can be queried? Thanks for any tips, Constantine. ________________________________ Elsevier B.V.

NullPointerException when executing geo:distance query
by Jesse Clark 27 Mar '14

27 Mar '14

Hi All, I am writing a feature that will rely on geo:distance to give me the distance between two points of latitude and longitude. I am a total n00b to GIS and GML so I may have messed this up, but based on a bit of research to figure out how to define the coordinate system and based on the example query from the BaseX docs I came up with the following query as a test: import module namespace geo = "http://expath.org/ns/geo"; declare namespace gml='http://www.opengis.net/gml'; let $vancouver := <gml:Point srsDimension="2" srsName="http://www.opengis.net/def/crs/EPSG/0/4326"> <gml:pos>49.40 -123.26</gml:pos> </gml:Point> let $seattle := <gml:Point srsDimension="2" srsName="http://www.opengis.net/def/crs/EPSG/0/4326"> <gml:pos>47.68 -122.37</gml:pos> </gml:Point> return geo:distance($vancouver, $seattle) I have this in a file and am trying to execute it from the CLI with: 'RUN [/path/to/file]' It pukes with this error: Stopped at [/path/to/file], 12/21: [GEO:GEO0002] java.lang.NullPointerException I am running off of the zip distribution of BaseX so I believe the geo module should be included. Any guidance would be greatly appreciated. Best, -Jesse

Re: [basex-talk] Class loading error
by Erol Akarsu 27 Mar '14

Sorry, throw this question, that is my fault. I have another question. Until now, I was able to read huge xml file (several Gbytes) through partition it and parse it with basex part by part. Do we have any new utility that can read 3-5G xml file and parse through basex?
