#449 spock does not work with ipython 4.x (jupyter)

[Carlos Pascual]

As expected, spock needs to be adapted to work with ipython 4.x (which was a large change, aka "The big Split", moving many components to the jupyter framework)

Here is what I get on my debian testing:

:~$ spock

See possibly relevant info:
http://jupyter.readthedocs.org/en/latest/migrating.html

http://ipython.readthedocs.org/en/stable/whatsnew/version4.html

[Carlos Pascual]

Note, the support can be restored by simply protecting the offending line with a try-except(pass):

  File "/home/cpascual/src/sardana/src/sardana/spock/ipython_01_00/genutils.py", line 1143, in run
    IPythonQtConsoleApp.version.default_value = release.version

... but we should also try to avoid the 4.x deprecation warnings

Just for info

test@diffabs6:~/.propellor$ rmadison ipython
debian:
ipython | 0.10-2 | squeeze | source, all
ipython | 0.13.1-2+deb7u1 | wheezy | source, all
ipython | 1.2.1-2~bpo70+1 | wheezy-backports | source, all
ipython | 2.3.0-2 | jessie-kfreebsd | source, all
ipython | 2.3.0-2 | jessie | source, all
ipython | 2.4.1-1 | stretch | source, all
ipython | 2.4.1-1 | sid | source, all

so the problem is for now with ipython 2.4.1

We are trying to see with the ipython Debian/Ubuntu maintainer which version will be available in the next Debian stable release.

Cheeers

I sent a patch for this to the devel list.
Note that PyTango and taurus also need fixing (https://github.com/tango-cs/PyTango/pull/14 , https://sourceforge.net/p/tauruslib/tickets/274/)

Carlos, thanks for your contribution it is already part of the develop branch.

I've added an aditional commit, correcting some wrong configuration that was raising other warning messages.

It may be that working with an old version of PyTango one still sees the following deprecation working. But its origin is the PyTango code. This would look like this:
