Java functions, packages, and ADMIN privileges
by Charles Duffy 22 Mar '12

22 Mar '12

Howdy -- The ability to call arbitrary Java code from XQuery being accessible only to users with ADMIN privileges is generally sensible for obvious reasons. However, it would be useful for users with ADMIN privileges to be able to install packages in such a way as to make classes contained therein accessible to less-privileged users. Does such a mechanism already exist? If not, thoughts on feasibility?

webdav issue using oxygen
by Maximilian Gärber 22 Mar '12

22 Mar '12

Hi, following the steps on http://docs.basex.org/wiki/Integrating_oXygen for accessing resources via webdav, I guess it should be possible to change and save xml files. Doing so, actually empties the db and adds a "RAW" xml resource to it. This happens with the latest Snapshot (7.2). Any other Oxygen users out there? Regards, Max

Ask about BaseX event for more than one context
by truc.cam＠emotive.de 22 Mar '12

22 Mar '12

Dear BaseX team, Please see the attachment. When I use events for 2 contexts, just the first one can notify.If the notification of the 2rd context happens, the result should be "1 2 3 4". If I replace "xquery2.execute(context2)" by "xquery2.execute(context1)", I will receive right result. But this is not what I want to do. Thanks in advance. Best regards

REST API now returning exceptions as HTML?
by Charles Duffy 21 Mar '12

21 Mar '12

Howdy -- Historically, the BaseX REST API has handled exceptions by returning only the exception content itself. I just ran a build against current SVN, and received the following: <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1"/> <title>Error 400 Stopped at line 1, column 75: [XPST0017] Unknown Java function 'net.dyfis.svnkit_wrapper.SvnWrapper.cat(...)'.</title> </head> <body><h2>HTTP ERROR 400</h2> Problem accessing /rest. Reason: <pre> Stopped at line 1, column 75: [XPST0017] Unknown Java function 'net.dyfis.svnkit_wrapper.SvnWrapper.cat(...)'.</pre><hr />Powered by Jetty:// </body> </html> Is this now desired/documented/ongoing behavior?

Debugging jar loading (Java interface)
by Charles Duffy 21 Mar '12

21 Mar '12

Howdy -- I'm trying to include (and use) a jar in a package, and not having any luck of it just yet. Could I get any guidance on what I might be missing here? === BEGIN expath-pkg.xml <package xmlns="http://expath.org/ns/pkg" spec="1.0" name="http://dyfis.net/svnkit-wrapper" abbrev="svnkit" version="0.1"> <title>Subversion Wrapper</title> <xquery> <namespace>http://dyfis.net/svnkit-wrapper</namespace> <file>svn.xq</file> </xquery> </package> === END expath-pkg.xml === BEGIN basex.xml <package xmlns="http://expath.org/ns/pkg"> <jar>svnkit-wrapper.jar</jar> <class>net.dyfis.svnkit_wrapper.SvnWrapper</class> </package> === END basex.xml === BEGIN svnkit/svn.xq module namespace svnkit = "http://dyfis.net/svnkit-wrapper"; declare namespace j="java:net.dyfis.svnkit_wrapper.SvnWrapper"; declare function svnkit:cat($path as xs:string) as xs:string { j:cat($path) }; declare function svnkit:cat($path as xs:string, $rev as xs:integer) as xs:string { j:cat($path, $rev) }; === END svnkit/svn.xq ...where "svnkit-wrapper.jar" contains a thin wrapper around TMate's SVNKit library, allowing direct access to Subversion resources through a simpler API (providing static functions only, abstracting away session management and the like). However, when I try to call svnkit:cat($subversion_url), the following is returned: [XPST0017] Unknown Java function 'net.dyfis.svnkit_wrapper.SvnWrapper.cat(...)'. I can call net.dyfis.svnkit.wrapper.SvnWrapper("") through Jython and other JVM-based interpreters, so I'm confident that the jar correctly exposes it. Any pointers on what I might be doing wrong in the packaging?

Well, then it seems after all, that the token alternative provides the highest degree of flexibility and security :) I guess, if there are no other suggestions, it should be discussed how to implement it.

Use of unsalted password hashes
by Charles Duffy 18 Mar '12

18 Mar '12

Howdy -- I'm a bit concerned about storing password hashes unsalted -- compared to a salted hash, this makes a stolen database easier to retrieve user passwords from, dangerous if users use their passwords for other purposes as well. Would salting (and perhaps stretching) the hashes be considered a reasonable feature to support in the future?
