Re: [basex-talk] Bug in 7.9: REMOVE over WebDAV not working

Hi Andreas,

thanks for the bug report. You may be surpised, but the problem boils down to an XQuery inlining issue, which can be reproduced via the query

()/x[function($x as item()){1}(.)]

I have opened a new GitHub issue [1]; we will keep you updated once this is fixed.

Hi Andreas,

could you please check if the problem persists with the latest snapshot [1]? Does the problem also happen with another WebDAV client?

Thanks in advance, Christian

removing a folder/collection over WebDAV does not work. The problem can be easily reproduced by creating a folder/collection using 'cadaver' and then trying to remove it. I was also able to reproduce the problem using Python and a Python webdav driver.
