Re: [Ripple-implementation] Ripplesite under Cygwin

[Ryan F. <rf...@gm...>]

Hi Kasper.  That's awesome that you can help out!  I'm cc'ing the
ripple-implementation list which is for technical discussions of
ripplesite.  You should subscribe to that list at
http://sourceforge.net/mail/?group_id=120019.

(There's also a ripple p2p implementation that I'm working on that
will eventually merge with ripplesite's front end and replace its
local payment and routing with distributed versions.  I'm developing
that much more actively at the moment.  Let me know if you'd prefer to
help with that.  I'm using twisted for networking and sqlalchemy as an
ORM.)

The latest ripplesite codebase has been ported to Django 0.95 and is
available by svn from:

http://svn.ripplepay.com/ripplesite/

login as guest/guest.  I'll set up commit privileges for you as
necessary.  I haven't packaged this code as a sourceforge release yet
because it hasn't been completely tested.

I see that Django has released version 0.96, which looks very
compatible with 0.95 code, so we should probably be using that.

I also have a trac instance that I used awhile back that I can and
will revamp for ripplesite development.

Django has an excellent tutorial and documentation at:

Right now the code bypasses the django db module and uses the psycopg
Postgres python DB-API module directly (a holdover from django 0.91
which didn't support transactions directly).  Replacing psycopg with
pysqlite in those places (payment.py and routing.py) could very well
work.

William Waites has made a start incorporating django transactions into
the code (see the 'Ripplepay + Dialstation' thread of rippleusers for
code attachments), but reports that it isn't working yet.

Yes.  It has a built-in development server.  You'll need to tweak it a
bit to serve images and css though:

So far backend testing has been semiautomated using testutil.py, which
allows you to populate a database from the command line, run a
sequence of random payments against it, and then verify the results.
I've only tested the web interface manually so far.  Django 0.96
apparently has an integrated test module that may help us with more
automation.

A local installation will try to send emails when testing the web
interface (but not when just doing backend command line testing).
What I've done so far is use a gmail account:  if your gmail username
is 'kasper', you can send email to 'kasper+1', 'kasper+2', or
'kasper+xxxxx' and they'll all get to the same account.
