First the page worked like a charm. But then I figured I'd like to see how
mod_python handles a situation where the page has an infinite loop in it.
I coded a page with a code like "while True:" etc. in it and ran it. (The code
had a call to session too, so session was initialized.) I noticed that the
script was newer killed (this is bad, PHP handles this with its time limit). I
had to restart httpd then (which killed the script).
Now after that loop test the session variable does not work anymore. I get
that "unsubscriptable object" error message.
I figured that maybe the session data is corrupted and deleted the dbm file
from /tmp. That did not help. I've also restarted httpd multiple times.
The weirdest thing about this is that the httpd is preforked, so the session
should exists only in memory. If the session exists only in memory, restarting
httpd should be enough.
Where can that corrupted session data be stored now? Does httpd save its state
into some files? Even rebooting the whole machine did not help.
I consider this bug a very serious thing because this is a blocker. Sessions
don't work anymore.
Also, some kind of handling for infinite loops should be implemented. Yes I
know, that should be described in another bug report, but let's fix this
session thing first.
I have high hopes for mod_python as it integrates an excellent language to an
excellent web server and because it enables a powerfull and easy alternative to
PHP.
