Make zeromq and pyzmq optional packages

[vbraun]

The single cell server already requires zeromq+pyzmq, and the ordinary notebook server probably will soon. Since they are also useful to work with any kind of distributed memory machines, we should just make them default spkgs. They are also pretty small, about 2MB altogether.

These spkgs are based on version that William created in January 2011, but updated to the newest upstream version and include a SPKG.txt:

• http://www.stp.dias.ie/~vbraun/Sage/spkg/zeromq-2.2.0.p0.spkg
• http://www.stp.dias.ie/~vbraun/Sage/spkg/pyzmq-2.1.11.p0.spkg

I started to review the two spkg's. zeromq-2.2.0.p0.spkg installs successfully. I unpacked and re-packaged using sage-pkg without problems. I did see some tmp files lying around:

• SPKG.txt~
• spkg-install~

and pyzmq-2.1.11.p0.spkg has:

• SPKG.txt~

After install import zmq works and I experimented with some simple examples from the ZMQ guide.

If anyone wants to do some simple testing, you can grab the client and server scripts in: http://sage.math.washington.edu/home/bjones/sage-devel/zmq/, open two terminals and run:

1st terminal:

sage -python hwserver.py

2nd terminal:

sage -python hwclient.py

I updated the spkg files to remove the backup files and committed changes.

Sorry, looks like we missed in zeromq:

• .hgignore~

The pyzmq spkg looks good.

What's the procedure, after a positive review? A sage-devel vote on inclusion of the packages as standard?

First it should optional for some time, usually. So a vote to make it optional would usually be next.

I updated the zeromq spkg to remove the .hgignore~

I'll change this ticket to say "make optional package" and we can take it to sage-devel from there. We don't need to vote on that, only to make it standard.

As long as nothing else in Sage depends on zeromq, obviously zeromq should not be a standard package.

Looks good. Positive review.
