Re: [basex-talk] username after login with jetty's HashLoginModule AND parallel update queries
Hi, that's the way I have realized the login before, but now I combine this with the http basic authentication, because otherwise you can download all files in the webapp directory without being logged in. I have realized it in that way, but now I can't get the username of the user who is logged in. Is there any way to read the "org.eclipse.jetty.security.UserIdentity" attribute in the session? I always get an error: HTTP ERROR 400 Problem accessing /restxq/getSession/org.eclipse.jetty.security.UserIdentity. Reason: Stopped at D:/Projects/******/basex77/basex/webapp/restxq/utilities.xqm, 35/18: [BXSE0002] Stored attribute cannot be retrieved: SessionAuthentication.

Hi Florian, one way to solve your original problem might be (we used this before) is to make the file folder not accessible by the web, but just by the RestXQ stack and instead of directly accessing the file providing a RestXQ function which will retrieve the file, based on your user authentication. I am not sure about accessing jetty session variables from within the RestXQ stack. I'll have to check on this, if and how it can be achieved. You can not parallelize update queries, you will never be able to do that in an ACID-compliant database. It would always be possible to corrupt data with concurrent updating queries. However, locking is based on database-level, so you can write to different databases at the same time. Cheers, Dirk On 08/29/2013 12:23 PM, Florian Eckey wrote:

Hi Dirk, see comments (red). Cheers and thanks for your quick answer, Florian -----Ursprüngliche Nachricht----- Von: basex-talk-bounces@mailman.uni-konstanz.de [mailto:basex-talk-bounces@mailman.uni-konstanz.de] Im Auftrag von Dirk Kirsten Gesendet: Donnerstag, 29.

Thanks. J I am not sure about accessing jetty session variables from within the RestXQ stack. I'll have to check on this, if and how it can be achieved. It would be nice, if you have an answer how I can do this. So if you have a solution, please contact me. You can not parallelize update queries, you will never be able to do that in an ACID-compliant database. It would always be possible to corrupt data with concurrent updating queries. However, locking is based on database-level, so you can write to different databases at the same time. When I split the database in smaller databases, can I write in this little databases with one update function in parallel way? If yes, does this basex automatically or is there a special configuration or implementation necessary? Or other formulation: The sections in the database I would like to write parallel can be divided into more smaller databases. Is there any way to write parallel in different databases inside exactly one update function? Or must I use restxq calls for every parallel action? As you probably know, I want to optimize my apps performance. Maybe you or anyone else has some ideas to optimize performance in basex? Cheers, Dirk On 08/29/2013 12:23 PM, Florian Eckey wrote:
