Re: [basex-talk] Load 5GB xml using python
by Henning Phan 09 May '16

09 May '16

Hello,My case:1. A (non technical) user uploads a 5 GB xml which gets parsed by basex2. Does some queries to check and modify some values3. Downloads the modified 5 GB xml back. So I'm planning to allow the user to edit their xml through a web application and therefore the user must upload the xml to the web application. I'm using python and when I receive the xml I want to create a database by using the create function from the client API, but the create(name, content) forces me to load the 5GB in memory which it cannot handle. I read the java client API which takes a stream unlike the python API. Am I forced to use java? What options are there to solve this problem gracefully? Any options that involve Python? Thank you for reading this - Henning

Web application static files
by Murray, Gregory 06 May '16

06 May '16

Hello, I'm new to BaseX, and I'm setting up a simple web application (on Mac/Unix, using the ZIP distribution of BaseX). I'm unable to bring in static files like CSS. Following the documentation and the "dba" web application that comes with BaseX, I have included the following in the HTML: <link rel="stylesheet" type="text/css" href="static/app.css"/> to point to a file that resides here: ~/basex/webapp/bookplates/static/app.css I have a module sitting here: ~/basex/webapp/bookplates/controller.xqm with a function with these annotations: %rest:path("bookplates") %output:method("html") When I point my browser to http://localhost:8984/bookplates/ the server successfully returns the HTML, but when the browser tries to load the CSS it requests http://localhost:8984/bookplates/static/app.css and the server responds with a 404 saying "No function found that matches the request" as if the server is looking for a RESTXQ function. What am I doing wrong? Thanks, Greg

KILL session
by George Sofianos 06 May '16

06 May '16

I'm trying to create an environment where I can have mutliple BaseX Servers, and I can run 2-3 complex queries on them at a time. However, I want to have the ability to stop a running XQuery script for any reason. I assumed that's what would happen if I KILL the session using a BaseX client. However when I try to KILL a session I have the following issues: 1) BaseX client freezes and I have to CTRL-C to stop it 2) The session I try to kill is removed from the list, but the process continues to run. I have to force kill -9 the basex server for it to stop. Should I report this as a bug or is there another way to kill the running scripts? Thanks

User and Password in REST URL
by Mike Cobo 04 May '16

04 May '16

Hi all When invokling an XQuery via REST, eg. http://mydomain.com:8984/rest?run=scripts/myscript.xq I'm prompted to type in the user and password for authentication. This is ok when a script needs user authentication to connect to a database. But when the script only uses the XQuery processor to output a (generated) HTML page it would be easier if the user authentication could by included in the URL, eg http://mydomain.com:8984/rest?run=scripts/myscript.xq&user=tester&password=… Is there a way to bypass the authentication dialog this way? I tried with the parameters "user" and "password" as shown in the example above, but this dosn't work. ThnxMike

Re: [basex-talk] Runtime Exception

Dear Mansi, you could try to run the INSPECT command on the affected database, or all databases, in order to find out if your database has gone corrupt. Did you repeatedly come across this error?

Strange restxq path error "assigned to several functions"
by Maximilian Gärber 02 May '16

02 May '16

Hi, suddenly, I get a path error [1] for functions that worked just minutes ago. When renaming the functions again it sometimes resolves the issue. I have CACHERESTXQ = false But this "feels" just like a caching issue. Appeared while on 8.4.1, but same on 8.4.3 Any ideas? [1] Problem accessing /test/import-convert/19.2.xlsx. Reason: Stopped at /webapp/test/api/import.xqm, 55/10: [bxerr:BASX0003] Path "/test/import-convert/{$file}" assigned to several functions: /webapp/test/api/import.xqm, 55/10 /webapp/test/api/import.xqm, 55/10
