Tag: CORESVR
core_server.py
Log Message:
Definitely not yet ready for prime time, but need to check this in so I have
something to fall back on.
--- NEW FILE: core_server.py ---
#!/usr/bin/env python
"""The primary server for SpamBayes.
Currently serves the web interface only. Plugging in listeners for various
protocols is TBD. This is a first cut at creating a standalone server which
uses a plugin architecture to support different protocols. The primary
motivation is that web apps like MoinMoin, Trac and Roundup can use spam
detection, but they don't necessarily provide the mechanisms necessary to
save ham and spam databases for retraining. By providing protocol plugins
you should be able to fairly easily provide (for example) an XML-RPC
interface web apps can use. The core server takes care of all the training
bells and whistles.
Usage:
core_server.py [options]
options:
-h : Displays this help message.
-d FILE : use the named DBM database file
-p FILE : the the named Pickle database file
-u port : User interface listens on this port number
(default 8880; Browse http://localhost:8880/)
-b : Launch a web browser showing the user interface.
-o section:option:value :
set [section, option] in the options database
to value
All command line arguments and switches take their default
values from the [html_ui] section of bayescustomize.ini.

Protocol plugin interface:
o POP3
o NNTP
o Classifier for web apps (e.g. Trac, Roundup, Moin)
Web training interface:
User interface improvements:
o Once the pieces are on separate pages, make the paste box bigger.
o Deployment: Windows executable? atlaxwin and ctypes? Or just
webbrowser?
o "Reload database" button.
New features:
o Online manual.
o Links to project homepage, mailing list, etc.
o List of words with stats (it would have to be paged!) a la SpamSieve.
Info:
o Slightly-wordy index page; intro paragraph for each page.
o In both stats and training results, report nham and nspam.
o "Links" section (on homepage?) to project homepage, mailing list,
etc.
Gimmicks:
o Graphs. Of something. Who cares what?
