"User has already been assigned." and 500s errors with Docker
by Andreas Jung 11 Dec '14

11 Dec '14

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi there, I am experimenting with Docker and BaseX 8 (snapshot of yesterday). I wrote my own Dockerfile https://github.com/zopyx/docker-basex and create my own Docker image https://registry.hub.docker.com/u/zopyx/basex80/ My WebDAV test suite now throws continuously HTTP 500 errors and I see "User has already been assigned." messages on the basexhttp console. The BaseX log but talks about HTTP 200 responses. Thoughts?

BaseX 8.0: Updates, User Management
by Christian Grün 10 Dec '14

10 Dec '14

Hi all, Since a while now, BaseX 8.0 is on the agenda, and we are busy finishing all the features requested by you and ourselves. As promised, there will be no changes in the database layout: You can easily move on to 8.0 without needing to migrate your existing data. However, we have decided to discard the old user management in favor of a more up-to-date architecture [1]. Here are some of the most prominent changes: • An XQuery User Module allows you to manage users via XQuery • Permissions can now be manually edited (all credentials will be stored as XML) • Instead of md5, we now use salted sha256 hashes • Additionally, digest hashes are used for the new HTTP Digest Authentication, and for the existing client bindings (cram-md5 was dropped) As a result, credentials of existing databases cannot be migrated to 8.0. Moreover, the existing language bindings will need to be updated. The changes are marginal, so it shouldn't be a big deal [2]. If you want to help us, we welcome you to update your favorite bindings to the latest standard! And as you can guess… The latest snapshot is online [3]. Thanks for your attention, Christian PS: Our BaseX Users Meetup has been confirmed. It will be attached to the XMLPrague conference, and it will take place February 13 in the afternoon [4]. More to come! [1] http://docs.basex.org/wiki/User_Management [2] http://docs.basex.org/wiki/Clients [3] http://files.basex.org/releases/latest [4] http://lanyrd.com/2015/basex/

WebDAV issue in BaseX 8, how to track down
by Andreas Jung 10 Dec '14

10 Dec '14

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi there, I have a bunch Python code that runs with unittests perfectly against exist-db. However I have some issues with the WebDAV implementation of Base-X (tested against the latest 8.0 beta snapshot). In my case I am trying to read a file that exists over WebDAV (Pdb) print z_filename foo/index.html (Pdb) handle.listdir() [u'foo'] (Pdb) handle.listdir('foo') [u'index.html', u'index.xml'] But trying to open and read the file gives me a 400 error (Pdb) handle.open(z_filename) *** OperationFailedError: Server Error: 400 The BaseX log tells me about a 200 response: 20:37:05.917 0:0:0:0:0:0:0:1:56453 admin REQUEST [GET] http://localhost:8984/webdav/testing/foo/index.html 20:37:05.921 0:0:0:0:0:0:0:1:56453 admin 200 3.84 ms However I see this on the console: Stopped at ., 1/112: [XQST0109] Character map 'webdav' is not defined.

more thoughts
by Rob Stapper 09 Dec '14

09 Dec '14

Hi Christian, Now I'm still on it, I've another thought; c.q. request. With closures as datastructures we're half way an OOP'ish-implementation. The other half concerns class-methods. Modules work pretty good here, ( now it comes) however it would be nice if some sort of inheritance could be implemented. For example: I store my map:update-function ( see my previous mail) with some other map-sugar functions in "XQR.map"-module, which is just an extension in the BaseX map-module. If I don't want to be put up with both modules in my program, which for obvious reasons is a good attitude, I have to redirect all standard map-function calls in my self defined XQR.map-module to Basex's map-module. But now I find myself programming these redirections, which, for the same obvious reasons, is not an optimal situation. I was wondering if there is or maybe can be created, an easy way to redirect unresolved function calls within a module to a specified module. With or without entering W3C-territory. What's your opinion on this? Rob Stapper --- Dit e-mailbericht is gecontroleerd op virussen met Avast antivirussoftware. http://www.avast.com

Hello! I'm just a little lost, I can't find a way to insert a node into an xml using Java. The query works, but the database does not updated. Can you point me to the right direction (or to an easy example of insert node with update). Thank you for your help! David ᐧ

Bug in computed attribute constructor
by Hans-Juergen Rennau 08 Dec '14

08 Dec '14

Dear BaseX team, I think there is a bug in the computed attribute constructor. If the name expression evaluates to a value of type xs:string or xs:untypedAtomic and the value contains no prefix, the attribute name should be in no namespace. However, the following code: <node xmlns="http://www.infospace.org/pcollection">{ attribute a1 {'foo1'}, attribute {'a2'} {'foo2'} }</node> yields this result:<node xmlns:ns0="http://www.infospace.org/pcollection" xmlns="http://www.infospace.org/pcollection" a1="foo1" ns0:a2="foo2"/> While @a1 has the expected name, @a2 hasn't. I used the latest snapshot: BaseX 8.0 beta 95b7e5f [Standalone] Kind regards,Hans-Juergen http://www.w3.org/TR/xquery-30/#id-computedAttributes
