Okay, so I have a python script to serve up my webpage which provides a list of programs. Its in Python because it makes it obscenely easy to add new entries to it - just type up the description and the formatting is done automatically.
Now, for some very peculiar reason, if I access that page (/programs/index.py), sometimes it works. Other times though it serves up pages in /programs/phpbb2rss/index.py and in the url box still says that its /programs/index.py, or sometimes it will serve up /programs/azure/index.py and say that its /programs/index.py. Really wierd behavior.
I use no page forwarding anywhere on /progams/index.py, so i'm just completely confused.

To test it out, just go along to http://cerulean.pyresoft.com and click on the Programs link a few times. You'll see what I mean.

Here is /progams/index.py with lots of the html just taken away.

Code:

#!/usr/bin/python
from mod_python import apache

includes = apache.import_module("includes", log=1)
# iefix, navigation

def index(req):
   currentpage = "Programs"
   
   programs = []
   # Title then body.
   
   programs.append("pyrcbot: A simple, easy-to-understand IRC bot written in Python." + """
   As the  ... extendable.""")
   
   programs.append("phpbb2rss: Convert a phpBB forum page into an RSS feed." + """
   Converts ...... making of this program.""")
   
   programs.append("Azure: A web bot that crawls the net." + """
   ........
   other than crawl the web, following anchor tags though...""")
   
   ####
   
   req.content_type = "text/html"
   req.write("""

   # Fix ie problems if the browser is ie.
   req.write(includes.iefix(req))

   req.write("""

   req.write(includes.navigation(currentpage))

   req.write("""</ul>

   <h3 class="posttitle" style="background: transparent">Programs</h3><br />

   for program in programs:
      output = ""
      header = ""
      headerend = program.find("\n")
      linkend = program.find(":")
      if headerend == -1 or linkend == -1:
         output = "Bad entry"
         break
      header = program[linkend:headerend]
      body = program[headerend + 1:]
      output = "<p class=\"posttext\"><a href=\"" + program[0:linkend].lower() + "/\"><strong>" + program[0:linkend] + "</strong></a>" + header + "<br />" + body + "<br /><br /></p>\n\n"
      req.write(output)
   
   
   req.write("""
         </div>

         <div id="footer">

   </div>
</body>

</html>""")

mod_python generates pyc's for modules in a directory that apache can access. The problem is all your modules are named the same thing which causes the call to index to become ambiguous.

Oh wow, it was a simple answer. I was worried and started hacking away at the file.
Thanks alot Algorithms. Is there a simple solution, which will allow me to use index.py? If not, no harm done. I'd much rather have the pyc and rename each file.

I see i'll have to use different sub-interpereters, which seems a bit of an overkill for such a little thing. I'll just rename.
Cheers again.

I just write a simple load script called index.py where index.py?fetch=whatever.py would then call the fetch method which returns the file requested.

Thats sort of what I did. Instead of making different files just make what was a file into a different module, so file.py/file. Works well.
