Schevo 3.2.0 wrap up
Etienne Robillard
Hi everyone,
I have been quite silent in the past months so here's a
few updates on integration of Schevo DBMS in the notmm WSGI toolkit! :)
Firstly, I've decided to include xdserver package within notmm toolkit,
in hope that it can be used for internal uses by a new Schevo ORM
backend. This new ORM backend and xdserver packages can be found in
notmm.dbapi.schevo_orm.
Also, the Durus extended server is really working well
and I think it can be used more efficiently by third-party applications
needing concurrent access to Durus databases, so thanks very much
for having made Schevo a solid alternative to SQL-only DBMS! ;)
Moreover, I've also created a new field type which I called
BlowfishHashField, for storing hash values using the python-bcrypt
library. The code for BlowfishHashField is
class BlowfishHashField(HashedValue):
"""Field stored as a one-way hash using the ``bcrypt`` module."""
def hash_encode(self, value, salt=None):
try:
import bcrypt
except ImportError:
raise ImportError("The bcrypt library is needed for using
Blowfish encryption.")
if salt is None:
salt = bcrypt.gensalt()
hashed_value = bcrypt.hashpw(value, salt)
return self.hash_header + hashed_value
Next is notmm.dbapi.schevo_orm.DatabaseProxy, a proxy class which uses
__getattr__ builtin method for accessing Entity classes in a proxy-like
behavior. i.e:
>>> from notmm.dbapi.schevo_orm import DatabaseProxy
>>> db = DatabaseProxy('accounts')
would create a ``db`` instance with no side-effects, as
xdserver backend is used for handling database connections in
non-blocking mode (which is super cool btw.. ;)
Finally, I added a roadmap for Schevo 3.2.0 development. It's accessible
here: http://gthc.org/Schevo/Roadmap
I hope you liked this short summary of my current Schevo development
work, and feel free to ask questions if I made a point unclear of if you
any questions surrounding Schevo or the notmm toolkit!
Best Regards,
Etienne

1. To implement Durus authentication will requires changes in xdserver
client package to support generic username/password authentication.
2. Durus extended server supports socket connections all the way, so to
have secure authentication TLS/SSL encryption should be used, to not
send the username and password strings in plain-text.
3. Schevo-editor (SchevoGtk2) can be modified to support rsync protocol.
This will allow easy remote and local syncronisation of durus databases
from the main app window. For instance:
1. connect to remote durus server....
2. do custom authentication handshake....
3. if authentication works, use rsync to syncronize both databases...
4. refresh window to reflect updated/current database
Any thoughts ?
Thanks,
Etienne

is SQLAlchemy better suited for building twitter bots, social network
phishing games, fake linked in job posts, and related iphones and
facebook applications ?
I'll let you respond to the answer as an exercise.
Thanks,
Etienne

and will most likely continue using Schevo in the future, even if you
continue ignoring my posts.

Mathieu,
i have run very few benchmarks yet.. last time I checked with ab (apache
bench) it was sufficient for my use case (a small-medium blog website..)
also i believe Schevo/Durus is really a fair alternative to mongodb and
others, but without benchmarks its hard to measure. Over-shadowed by
other open source "competitors" perhaps ?
Have a great day,
Etienne
