I find that cgitb fails to show error context if I've changed my
default directory, so I tried to subclass cgitb and get it to save the
directory we were in when the program started. Didn't work. I'd
appreciate your eyes.
Problem--this apparently fails to find my sourcefile when #os.chdir is
uncommented from this cgi program
..........................
#! /usr/local/bin/python
import cgitb
cgitb.enable()
import os
#os.chdir('../')
1/0
..........................
What I thought would work:
..........................
from cgitb import Hook
import os
import sys
class myHook(Hook):
def __init__(self, display=1, logdir=None, context=5,
file=None,wkdir='xx'):
self.wkdir=wkdir
Hook.__init__(self, display=1, logdir=None, context=5, file=None)
def handle(self, info=None):
os.cwd(self.wkdir)
Hook.handle(self,info)
handler = myHook().handle
def enable(display=1, logdir=None, context=5):
wkdir=os.getcwd()
sys.excepthook = myHook(display, logdir, context,wkdir=wkdir)
..........................
But in fact, my exception handler doesn't even seem to get installed.
(I get python's usual tracebacks)
I'm probably over my head here, but...
What's wrong with the program where I attempt to subclass myHook?
Is this a reasonable way to get cgitb to survive directory changes?
