Subject: [Medusa-dev] Generating exe from Medusa
Message-ID: <s2c12396.001@mail.grintek.com>

Hi,

we have written an application using the Twisted Framework to generate
an Client Server.

Is it easier to use Medusa?

The reason i am asking is that we are having problems generating the
exe for the application using the installed Twisted application. 

I assume Medusa is also a package that one installs?

Have you got support to generate an exe using the Py2exe package?

Regards
Greg

probably not... maybe. Medusa is older, and more stable, but Twisted has
been refactored again and again, so is more refined, and probably better
documented.

It is a collection of pure python modules.

I suspect that the reason you are having problems with Twisted is it's
exensive support for different event-loops... probably some of which are
C extension modules (guessing here). 

If that is the case, then you might have more luck with medusa. However,
migrating Twisted code to medusa would not be that easy, as they are
fairly different. Twisted is much better supported these days, so you
might as well try and resolve the issues you are having with it through
the Twisted lists etc. I would also deal with the Py2exe people...

Message-ID: <20050704093504.56695.qmail@web41012.mail.yahoo.com>

Hi,

I got hold of a documentation that helped solved the
problem. I was able to run Medusa but i encountered
another problem. 
The problem is, that the web pages won't display the
stylesheet, javascript and graphics. It cannot find
the   referenced (href) files. I changed the links to
the files but to no avail. I don't know if I missed
something in Medusa configuration. Server code:

---------------------------------------
#!/usr/bin/env python

try:
    from medusa import http_server, xmlrpc_handler
except ImportError:
    print '\n' + '='*50
    print 'medusa/ package not found; install it.'
    print '='*50
    raise
        
import asyncore
from quixote.publish import Publisher
from quixote.server import medusa_http
from quixote import enable_ptl
enable_ptl()

# Server that exposes the links demo program on port
8080
PORT = 8080    # [1]

print 'Now serving the qxdemo.links demo on port %i' %
PORT
server = http_server.http_server('', PORT)
publisher = Publisher('quixote.hrmo')   
publisher.config.debug_log = "/tmp/debug"    
publisher.config.error_log = "/tmp/error"
publisher.setup_logs()
dh = medusa_http.QuixoteHandler(publisher,
'/quixote/hrmo/medusa-server.py', server)    
server.install_handler(dh)
asyncore.loop()

-------------------------------------------

Please give some hints. Thanks again.

Cheers!
Ed Biano

Hi,

I am new to Medusa and Quixote and was successful in
configuring Quixote demo using CGI
(http://localhost/cgi-bin/foo.cgi/). I would like to
use  Quixote demo in Medusa. The reason I would like
to use Medusa because of potential speed problem with
CGI. Can someone give me information or direct me to a
documentation on how to configure Medusa or Quixote to
make both work? Sorry, I googled and searched in the
Medusa mailing archive but found none.Thank you in
advance for your help.  

Cheers!
Ed

Subject: [Medusa-dev] Quixote Submit button and browser Back button
Message-ID: <20050715012644.14761.qmail@web41006.mail.yahoo.com>

Hi,

I am a Medusa and Quixote newbie, hacked the Quixote
demo and created a small app. The app authenticates
users,  displays a form which users can fill and
submit using a Submit button. It updates a database
and then displays the home page.

My problem is, when the home page is displayed and i
hit the browser Back button the same form is displayed
with all the information of the previous entry. And
when i hit the Submit button it again updates the
database.

I would like to have the form page expired or any
other solution you can suggest so that users cannot
submit the form again without being authenticated.  I
read about _q_access and session but i cannot figure
out how to do it. I think the browser Back button
issue is different from the normal program flow.

Please give some hints and thank you in advance.
 
Cheers!
Ed

Eduardo,

isn't this THE usual problem with Web-Apps? :)

You want to be sure that ONE PARTICULAR FORM only gets submitted once.

So, make this form unique:

add a HIDDEN input with a UNIQUE GUID (windows has a GUID in his API, there 
are MILLIONS of receipts out there, a MD5 of the current time.time() is 
quite fair)

when logging Info to database, store this guid. If a form with the same guid 
is submitted, reject that information

Add timeouts as appropriate (for example, each GUID is only valid for 0,5 
hours)

Harald

A good trick is to make the page that accepts the form return a 302
redirect to somewhere.  This makes the form submission disappear from
the 'back' history, and means that if someone hits the refresh button,
the form doesn't get submitted again.  These are the two big problems.

I'm not sure if that made sense, so here's an example:

You have a weblog comments page, /comments.  Someone enters a comment
in the form, then clicks "POST".  The browser POSTs the form to
/new-comment, which saves it in the database then returns a 302
redirect to /comments.  The browser picks this up and displays the
/comments page rather than /new-comment.

This is something that pretty much every well-written web app
does... it's really worthwhile.

Cheers,
Phil :)
