I've just taken a break from trying to debug the problem where
notebook fails
to respond to clicks on 'evaluate' to try out some bits of Sage that
I'd not
yet used: symbolic algebra.
I had typed in a simple bit of code
{{{
var('a'); var('b'); var('c')
|
}}}
{{{
c = pi - a - b
|
}}}
The first cell was OK but the second one hung up on me in a different
way:
There was the green line to indicate processing and the cursor moved
to the
start of the cell, but it just stayed like that. Clicked on the cell
and
pressed Shift-Enter again with same result.
This was on my windows box (XP/Internet Explorer).
I switched to my Linux laptop. I had logged out of the notebook on
there
prior to logging in to the windows box, but my browser had the 'thanks
for using sage'
message. For some reason I clicked the 'Back' button, rather than the
'login'
link and got:
Internal Server Error
An error occurred rendering the requested page. More information is
available in the server log.
Looking at the window from which I had started notebook I found:
2008/01/22 22:07 +0100 [HTTPChannel,5831,127.0.0.1] /sage/current/
local/lib/python2.5/site-packages/twisted/internet/defer.py:259:
exceptions.DeprecationWarning: Don't pass strings (like 'Bad token')
to failure.Failure (replacing with a DefaultException).
2008/01/22 22:07 +0100 [HTTPChannel,5831,127.0.0.1] Exception
rendering:
2008/01/22 22:07 +0100 [HTTPChannel,5831,127.0.0.1] Unhandled Error
Traceback (most recent call last):
Failure: twisted.python.failure.DefaultException: Bad token
By the time this had sunk in I looked back at the windows box and it
had
succesfully evaluated the cell that had been hanging. Tried again and
it
came back immediately.
I'm not sure what was going on.....
