Restxq and java
by meumapple 22 Apr '16

22 Apr '16

Hi, I have developed a restxq service, which executes a command via the process module. The command is actually java (java -cp ...) which actionates a linguistic parser: unfortunately the time of loading/opening of the java process is quite long (14 sec., also at the command line) even if the actual parsing is very fast. I am looking for a way to keep such a java process "open", so that a user's request can be satisfied much much quickier (while now the java process is opened and then closed for each single request). I am not sure this is a question for Basex users (the problem is only due to java), but I am not a java developer at all and I am trying to understand what can be done in this respect. Thanks! Joseph

file:read-binary error
by Maud Ingarao 20 Apr '16

Dear friends We updated 2 days ago from 8.2 to 8.4 and are experiencing a few strange things.

command script / batch-processing of xqueries
by Günter Dunz-Wolff 19 Apr '16

19 Apr '16

Hi all, hi Christian, I'm running some xqueries to create and update basex dbs over and over again. They all depend on the basic db 'mydata'. Whenever mydata is updated, I have to update the other dbs. 1. xq-file: db:create('mydata', path/to/my/xml ..... 2. xq-file: db:create('searchindex', let $data0 := db:open('mydata') ..... 3. xq-file: db:create('indd-xml', let $data0 := db:open('mydata').... 4. and so on First question: Is there any way to put the whole process into one command-script? Or is there any kind of other batch-processing? Second question: So far I'm creating the db 'mydata' with the GUI. I want to integrate the creating into the batch-processing via XQuery. In generell I know the create-command, but where to put the options: use XInclude, chop-whitespace OFF and Fulltext Language German internal, Stemming OFF, Case Sensitive and Diacritics ON? Can't find it in the docs. Thanks for any help, Günter

Non-default admin user/pw for BaseX on Docker image
by Mike Cobo 18 Apr '16

18 Apr '16

Hi BaseX team, hi all I want to create a docker image based on the existing basexhttp image, but with other credentials for the admin user. For this reason I added an edited .basex file with changed password (here: mypassword) to the new docker image: .basex: ...# Client/Server ArchitectureHOST = localhostPORT = 1984SERVERPORT = 1984USER = adminPASSWORD = mypasswordSERVERHOST = ... Dockerfile: FROM basex/basexhttp:latestMAINTAINER Mike <myemail(a)mail.com>COPY .basex /srv/VOLUME ["/srv/BaseXData", "/srv/BaseXWeb"] After starting the docker container I checked if the edited file can be found under the path "/srv/.basex". The file is there but when I want to login to the database (or run an XQuery script via the browser) I cannot login with admin/mypassword. The erreor message is: Connection failed: Access denied. But I can still use the default user/pw (admin/admin) to connect. Why is the changed .basex file not loaded/parsed when starting the BaseX (http) server on the docker container? Should the file be copied to a different path? Best regards,Mike

Exception for async + client
by Strasser Pablo 15 Apr '16

15 Apr '16

Hi, Playing with the nice new async and client library together to generate asynchronous remote query I got randomly the following exception: java.lang.ClassCastException: org.basex.query.value.seq.tree.BigSeq cannot be cast to org.basex.query.value.item.Item at org.basex.query.value.ValueBuilder.concat(ValueBuilder.java:37) at org.basex.query.expr.List.value(List.java:147) at org.basex.query.QueryContext.value(QueryContext.java:420) at org.basex.query.expr.If.value(If.java:131) at org.basex.query.expr.gflwor.GFLWOR.value(GFLWOR.java:78) at org.basex.query.QueryContext.value(QueryContext.java:420) at org.basex.query.value.item.FuncItem.invValue(FuncItem.java:129) at org.basex.query.func.FuncCall.invoke(FuncCall.java:87) at org.basex.query.func.FuncCall.value(FuncCall.java:159) at org.basex.query.value.item.FItem.invokeValue(FItem.java:45) at org.basex.query.func.hof.HofUntil.value(HofUntil.java:27) at org.basex.query.func.hof.HofUntil.iter(HofUntil.java:18) at org.basex.query.QueryContext.iter(QueryContext.java:409) at org.basex.query.expr.List$1.next(List.java:134) at org.basex.query.MainModule$1.next(MainModule.java:123) at org.basex.core.cmd.AQuery.query(AQuery.java:92) at org.basex.core.cmd.XQuery.run(XQuery.java:22) at org.basex.core.Command.run(Command.java:398) at org.basex.core.Command.execute(Command.java:100) at org.basex.server.ClientListener.run(ClientListener.java:136) This happen with the attached code where 10.0.0.5 is another basexserver than the current one. The code is a preliminary test on launching system command on another basexserver asynchronously. Have a nice evening. Pablo

Problems with IPA diacritics display
by Bowers, Jack 14 Apr '16

14 Apr '16

Hi (again), (I have now signed up for the list) There seems to be a problem with displaying results in which the text has with IPA diacritics. The problem is only in the display of the data and not the source xml files or even those extracted from the search results in which these display problems are found. The problem is also not universal, in some cases they display fine, in others there are gaps in the text and characters overlapping. I've attached a screenshot of the results and a small file in which there are such characters diacritics which you can test on. For the record, I did activate the 'diacritics' option in the 'Full Text' portion of the menu, and I do have the IPA zip folder in that of the database source files It's essential for us to be able to display these characters and strings correctly for our research it would be greatly appreciated if you could give any insight or consider this issue in any future software updates! Thanks very much!

Re: [basex-talk] RESTXQ and Website-Building
by Marco Lettere 12 Apr '16

12 Apr '16

Hi Günter, sorry for the delay but here you go with a very small example that should show off what I told. You can copy the .xqm files into the webapp dir of a basex installation and and the .css files into the corresponding static folder. Then invoke the "entrypoint" RestXQ from within your browser with an url similar to http://localhost:8984/myapp/page1?user=Marco As you can see the HTML page built from the entrypoint is composed of three parts. One that selects the styles to apply according to the user being anonymous or not. Then a common header markup is generated and finally a dynamic part that depends on the page element of the path. It's really not anything special but nevertheless it should be useful in clarifying the approach. Hoffe es gefaellt dir. Herzliche Gruesse, Marco.

Thank you Christian, I checked the issue of the subject with the latest release and now it is working. But the BaseX843-20160407 release introduces a different issue (supposedly), that is a java.lang.StackOverflowError exception you can reproduce implementing a restxq with a recursive function, as in the following example: --- module namespace api = "urn:api"; declare function api:fact($val) { if ($val = 1) then 1 else $val * api:fact($val - 1) }; declare %rest:path('myapi/{$v}') %rest:GET function api:impl_GET($v) { <result>{api:fact($v)}</result> }; --- Regards, Vincenzo 2016-04-06 15:48 GMT+02:00 Christian Grün <christian.gruen(a)gmail.com>: > Il problema è risolto [1,2]; grazie di nuovo. > > [1] https://github.com/BaseXdb/basex/issues/1281 > [2] http://files.basex.org/releases/latest/ > > > > On Tue, Apr 5, 2016 at 12:53 PM, Christian Grün > <christian.gruen(a)gmail.com> wrote: > > Thanks Vincenzo, > > > > I could reproduce the problem [1], and we’ll fix it soon. > > > > Generally, I’d recommend you to avoid declaration of variables that > > will never be used.
