[Bug 330374] [NEW] decompyle does not work for python 1.5-2.1 pyc's

[issaqua]

Public bug reported:

Binary package hint: decompyle

Description:	Ubuntu 8.10
Release:	8.10

apt-cache policy decompyle
decompyle:
  Installed: 2.3.2-4.1
  Candidate: 2.3.2-4.1
  Version table:
 *** 2.3.2-4.1 0
        500 http://mirror.internode.on.net intrepid/universe Packages
        100 /var/lib/dpkg/status

When I try to run the decompyle on older code it errors out (tried it on
version 1.5 and 2.1 pyc's)

I think /usr/share/pyshared/decompyle/Scanner.py should have the
following code

        try: FOR_ITER      = self.dis.opmap['FOR_ITER']
        except: FOR_ITER   = None
        try: GET_ITER      = self.dis.opmap['GET_ITER']
        except: GET_ITER   = None
        try: FOR_LOOP      = self.dis.opmap['FOR_LOOP']     # Added for older python versions.
        except: FOR_LOOP   = None

and

            if ord(code[i]) in (FOR_ITER, GET_ITER, FOR_LOOP):   # Added
FOR_LOOP for older versions.


As the older versions of python seem to use FOR_LOOP instead of FOR_ITER or GET_ITER.

When I made these changes it could decompile the older version code -
not sure if I broke anything else - I'm not a python guru by any means.
