QLime install notes

[ken...@gmail.com]

Cool, Shalabh! Toying around with QLime a bit...interesting.

Some notes from install on a fairly vanilla Debian box. Mainly prereqs.

1) Need medusa for install of demo

2) Medusa run script example in handbook uses server/qlime_server.py
script in tar, not installed one in lib/python, or whereever (ie,
python ../server/qlime_medusa.py demo.conf). So if you change port #,
for example...you're using wrong one.

3) Demo fails w/o pyPgSQL installed

4) noteapp fails b/c /home/shalabh...blah is hardcoded/included
somewhere (ah...in demo.conf. Requires updates to paths, and they have
to be absolute. That's fine...just mention it a little more explicitly,
maybe, in install. When I'm playing around with something like this, I
try to get up and running QUICK, so I'm not searching for things to
edit...)

Looks quite interesting, though! I love Quixote, and your OR mapping
stuff is pretty jazzy. Congrats on all the good work!

Yes. I'll fix the doc.

The files should be indentical - i.e. the tar one and one in
site-packages/qlime/server/qlime_medusa.py so you can run either. Of
course you'll have to change the port in the one you are using, but I'll
just point people to one file to avoid confusion.

Btw, another item missing from the docs is that you can pass a second
argument to qlime_medusa.py, which can be a Quixote conf file. So,

$ python qlime_medusa.py qlime.conf quixote.conf

Hmm.. you're right. This is a bug (it's a bogus requirement), now fixed.

Good point. I'll try to get rid of the absolute path requirement.

Thanks for your feedback! This is just the kind of stuff I am looking for.

I was unable to import qlime 0.51 as follows:

This is because QLime 0.51 works with Quixote 2.0a4. Looks like you have
2.0a5 (which removed SessionPublisher, merged it into Publisher).

QLime 0.52 (unreleased) works with 2.0a5, so you could either wait till
it is released, or simply change all occurences of SessionPublisher to
Publisher in session.py to make it work.

Hope this helps. Let me know if you have other problems.

Also, session_mgr needs to be changed to session_manager in session.py.
