Dear All, I found I needed support for taint mode in python and have done some work to realise this. It's by no means complete at this time, but I'm floating this idea on this group to see how much interest there is.
The implementation is pretty simple: - an extra field in PyObject to maintain the taint status - a couple of extra functions __gettaint__() that returns the taint status and __settaint__(value) that sets the taint value, returning the previous status - an additional command-line flag -a and environment variable PYTHONIGNORETAINT that suppress taint checking - a few macros defined in Objects/object.h to support taint management - a new built-in exception, PyExc_TaintError, for reporting operations on tainted objects You can pick up the diff at http://www.cats-muvva.net/software/Python-taint-diff-3.0rc3.tar.bz2 This diff is ONLY for 3.0RC3. Given that I have only a limited understanding of the internals of Python (but it's very clearly written), I'm sure there are some behaviours I've overlooked. I have done very little testing at this point, but, at least, everything compiles!
