Moving to Java 7
by Christian Grün 04 Apr '14

04 Apr '14

And another note on the future of BaseX: BaseX 7.8.x and (possibly) BaseX 7.9 will be the last versions based on Java 6. With BaseX 8.0, we'll switch - and we have already switched - to Java 7. We have chosen to move on because the official support for Java 6 has ended quite a while ago. Next, Java 7, gives us much better OS support for local file operations and numerous other minor features that allow us to further improve the performance and quality of BaseX. I hope you all will be able to move on with us; have fun, Christian

Re: [basex-talk] Is there a C++ Implementation
by Maximilian Gärber 04 Apr '14

04 Apr '14

Hi, there is a .NET version called nxdb. I converted the jars using IKVM some time ago myself and it run just fine. Also, since it is BSD licensed, one could use Excelsior JET to generate native code. If you just want a processor (not a xmldb) you could try Zorba XQuery as well, that is C++ Regards, Max 2014-04-04 6:49 GMT+02:00 Alex Taylor <support(a)novixys.com>: > Hi > > This software BaseX is excellent.

Is there a C++ Implementation
by Alex Taylor 04 Apr '14

Hi This software BaseX is excellent. Really good at processing large files. I would like to know if there is a C++ implementation of the core engine, or there are plans for developing a C++ implementation? Thanks in advance. -- Alex Taylor Senior Developer Novixys Software http://www.novixys.com

Re: [basex-talk] server class trouble
by Dirk Kirsten 03 Apr '14

Hi Jason, I am glad you figured it out - Problems that solve themselve are my favorite ones :-) I just cc'ed the mail to the mailing list so everyone can benefit from the information. I still want to point out that the problem is not the opening of the database, but the way you do it. You did use the local way and the local database access and client/server way are not synchronized, so you run into this error. Instead the content of your openDB() function you could have initialized your session before and then executed: session.execute("Open adsss") This way, the transaction monitor would be taking care of the synchronization.

logging in basex-api (restxq)
by Maximilian Gärber 03 Apr '14

03 Apr '14

Hi, I'd like to use log4j with basex-api but cannot figure out how to make this work. Currently, everything goes to the console. The basex-api POM defines a dependency on slf4j-nop which as far as I undertand logs to dev/null Do I need to change the basex-api POM file to replace it with the slf4j log4j adapter? And: what setting do I need to change the target output of the trace() function? My web app POM contains these settings: .... <dependency> <groupId>log4j</groupId> <artifactId>log4j</artifactId> <version>1.2.17</version> </dependency> <dependency> <groupId>org.eclipse.jetty</groupId> <artifactId>jetty-server</artifactId> <version>${jettyVersion}</version> </dependency> <dependency> <groupId>org.basex</groupId> <artifactId>basex-api</artifactId> <version>${BaseXVersion}</version> ...

Hello all, I'm scanning millions of XML records imported from CSV looking for instances of 'bib_rec_id' which are non-numeric. Which of these two is if-statements likely to complete earlier? for $a in (/csv/record/bib_rec_id) return if ($a castable as xs:integer) then ... blah or if (matches($a, '^[0-9]+$')) then ... blah Yes - I'm trying it out now, but I suspect it will be quicker to ask than wait for either query to complete. TIA. ________________________________ Elsevier B.V. Registered Office: Radarweg 29, 1043 NX Amsterdam, The Netherlands, Registration No. 33156677, Registered in The Netherlands.

server class trouble
by Jason Ricles 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

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', '
