move notebook to flask/wsgi-based notebook

[jason]

This ticket tracks the progress to move the notebook to a flask/wsgi-based notebook.

spkg:

• ​http://sage.math.washington.edu/home/jason/twisted-11.0.0.spkg (from #11874)
• ​http://sage.math.washington.edu/home/jason/sagenb-0.9.0.spkg (this includes all dependencies not already in Sage)

apply:

• Apply the patch from #11078 to the normal sage repository
• DO NOT apply trac-11080-sagenb_dependencies-spkg.patch to the $SAGE_ROOT repository (this updates the spkg dependencies lists to include the new spkg). (that patch is only if we end up using a sagenb_dependencies spkg)

Relevant code repository: ​http://code.google.com/r/jasongrout-flask-sagenb/

Explicit instructions: Replace $SAGE_ROOT with the root sage directory

cd $SAGE_ROOT
./sage -f http://sage.math.washington.edu/home/jason/twisted-11.0.0.spkg
./sage -f http://sage.math.washington.edu/home/jason/sagenb-0.9.0.spkg
cd devel/sage
../../sage -hg qimport http://trac.sagemath.org/sage_trac/raw-attachment/ticket/11078/trac_11078.patch
../../sage -hg qpush
cd ../../
./sage -br

removed #11078 from list as the fix is included in the 11503 command line patch.

(for future reference, after this is merged, jmol is a high priority. These two tickets deal with these changes:

• #11496 (update jmol script in local/bin to reflect move of jmol directory to local)
• #11503 (updated spkg and paths for move of jmol directory)
• #9238 (for reference -original Jmol enhancement ticket but heavily laden with pre-flask notebook stuff)

Again, this is only FYI and for further reference.

I get the following error when I try to apply the spkg dependencies patch. Everything else seems to work. I'm still checking functionality...

With 4.8.alpha4, what is described here does not work. I redid everything. The .spkgs seem to install without error. The patch for this ticket does not work and the notebook fails to launch with the error:

It's possible that the SAGE_ROOT patch needs to be rebased to 4.8.alpha4. Let me check. Thanks for the test

[jason]

Jonathan,

I think the problem is that you didn't apply the patch here to the SAGE_ROOT repository. I've updated the instructions above with explicit commands.

[jason]

I'm checking now into the error you posted in your second. It appears that there is indeed a problem with the sagenb spkg not overwriting the old notebook.

[jason]

For future reference, here are the instructions if we had a sagenb_dependencies spkg. DON'T USE THESE--use the instructions in the description of the ticket.
