Re: [Zope-dev] urgent: string exceptions

11 Apr 2003

      ...
You can catch most string exceptions.  "Bad Request" cannot be caught
because (afaik) the string isn't interned because it has a space in it.
You're skating on thin ice there, mate!  This is an accident of the
implementation.
...
As a workaround, I'd use except: then do
try:
   something
except:
   e = sys.exc_info()
   if e[0] == 'Bad Request':
      do something
   raise
Why is there code writing

  raise 'Bad Request'

That code should be fixed!  It ought to use a class exception; if
that's not possible, it ought to at least give the string a global
name, like so:

BadRequest = 'Bad Request'

  .
  .
  .
  raise BadRequest
