:ref:`davlink`
--------------

Fixed several problems in :ref:`davlink`:

- Added a :srcref:`davlink.jnlp </lino/media/applets/davlink.jnlp>` 
  file and a :srcref:`manifest.txt </java/davlink/manifest.txt>` file
  as explained in the `Deployment Trail 
  <http://docs.oracle.com/javase/tutorial/deployment/TOC.html>`_.
  
- Added a file :srcref:`davlink_jnlp_test.html
  </lino/media/applets/davlink_jnlp_test.html>` which 
  is like :srcref:`davlink_test.html 
  </lino/media/applets/davlink_test.html>`
  but using JNLP.

- To facilitate further experimenting, 
  :mod:`lino.extjs.ext_renderer` can now generate either with or 
  without JNLP depending on whether ``USE_DAVLINK_JNLP`` is True or 
  False.
  
- AFAICS both methods work the same, so I prefer the simple 
  applet method until proof of the opposite.
  
- It seems that the main problem was the fact that :meth:`DavLink.init` 
  tried to set the SecurityManager. 
  It seems that this was some obsolete technique,
  that it is simply not allowed and not necessary to change the 
  security manager.

- :meth:`DavLink.open` did not write a traceback to the console
  when some Exception occured.
  
- :meth:`DavLink.open` 
  returns a string with the error message when it fails, 
  but
  `davlink_test.html` did not report this error message::
  
    document.applets.DavLink.open(webdavURL);
    
  Replaced this by::
  
    var msg = document.applets.DavLink.open(webdavURL);
    if (msg) alert(msg);
  
- Could not find any reason for a NullPointerException on Windows7 
  reported by Gerd. 
  Added a message "DavLink.generate_default_prefs() done" in order to 
  continue testing on Monday.
  
- In `davlink_test.html` and `davlink_jnlp_test.html` added a JavaScript 
  function and a link to 
  invoke :meth:`DavLink.generate_default_prefs` with one click instead 
  of using the brute force method of deleting the :file:`prefs.xml` file.

All the above has been tested only using IcedTea and OpenJDK.

Note: for efficient testing on a live webdav-enabled :ref:`welfare` 
database:

- go once to the detail of some Event/Note which is being 
  printed as webdav (i.e. a CV)
- click the permalink button
- Copy the URL line of your browser and then launch it directly to this 
  url from the command line::

    $ chromium-browser http://127.0.0.1:8000/api/notes/MyNotes/28?an=detail
    


test_sdist
----------

I finally got ``fab test_sdist`` to run. 
And found the reason for 
the problem with the last release reported by Joe:
The `install_requires` of Lino specified 
'north' instead of 'North'.
Also 'PyYAML' was missing in `install_requires`.

Now there's just one ImportError:: 

  Could not import settings 'lino.projects.belref.settings' (Is it on sys.path?): No module named lino_welfare.modlib.statbel
  
(which is normal. TODO: move 
lino.projects.belref to lino_welfare)
or statbel from lino_welfare to lino)
