c24a23b1f198 Added implementation notes for [re]set_exc_info(). Guido van Rossum <guido@python.org> parents: 28086 diff changeset	3043 Long ago, when none of this existed, there were just a few globals:
c24a23b1f198 Added implementation notes for [re]set_exc_info(). Guido van Rossum <guido@python.org> parents: 28086 diff changeset	3044 one set corresponding to the "hot" exception, and one set
c24a23b1f198 Added implementation notes for [re]set_exc_info(). Guido van Rossum <guido@python.org> parents: 28086 diff changeset	3045 corresponding to sys.exc_ZZZ. (Actually, the latter weren't C
c24a23b1f198 Added implementation notes for [re]set_exc_info(). Guido van Rossum <guido@python.org> parents: 28086 diff changeset	3046 globals; they were simply stored as sys.exc_ZZZ. For backwards
c24a23b1f198 Added implementation notes for [re]set_exc_info(). Guido van Rossum <guido@python.org> parents: 28086 diff changeset	3047 compatibility, they still are!) The problem was that in code like
c24a23b1f198 Added implementation notes for [re]set_exc_info(). Guido van Rossum <guido@python.org> parents: 28086 diff changeset	3048 this:
c24a23b1f198 Added implementation notes for [re]set_exc_info(). Guido van Rossum <guido@python.org> parents: 28086 diff changeset	3049

c24a23b1f198 Added implementation notes for [re]set_exc_info(). Guido van Rossum <guido@python.org> parents: 28086 diff changeset	3058 cause of subtle bugs. I fixed this by changing the semantics as
c24a23b1f198 Added implementation notes for [re]set_exc_info(). Guido van Rossum <guido@python.org> parents: 28086 diff changeset	3059 follows:
c24a23b1f198 Added implementation notes for [re]set_exc_info(). Guido van Rossum <guido@python.org> parents: 28086 diff changeset	3060
c24a23b1f198 Added implementation notes for [re]set_exc_info(). Guido van Rossum <guido@python.org> parents: 28086 diff changeset	3061 - Within one frame, sys.exc_ZZZ will hold the last exception caught
c24a23b1f198 Added implementation notes for [re]set_exc_info(). Guido van Rossum <guido@python.org> parents: 28086 diff changeset	3062 in that frame.
c24a23b1f198 Added implementation notes for [re]set_exc_info(). Guido van Rossum <guido@python.org> parents: 28086 diff changeset	3063
c24a23b1f198 Added implementation notes for [re]set_exc_info(). Guido van Rossum <guido@python.org> parents: 28086 diff changeset	3064 - But initially, and as long as no exception is caught in a given
c24a23b1f198 Added implementation notes for [re]set_exc_info(). Guido van Rossum <guido@python.org> parents: 28086 diff changeset	3065 frame, sys.exc_ZZZ will hold the last exception caught in the
c24a23b1f198 Added implementation notes for [re]set_exc_info(). Guido van Rossum <guido@python.org> parents: 28086 diff changeset	3066 previous frame (or the frame before that, etc.).

c24a23b1f198 Added implementation notes for [re]set_exc_info(). Guido van Rossum <guido@python.org> parents: 28086 diff changeset	3068 The first bullet fixed the bug in the above example. The second
c24a23b1f198 Added implementation notes for [re]set_exc_info(). Guido van Rossum <guido@python.org> parents: 28086 diff changeset	3069 bullet was for backwards compatibility: it was (and is) common to
c24a23b1f198 Added implementation notes for [re]set_exc_info(). Guido van Rossum <guido@python.org> parents: 28086 diff changeset	3070 have a function that is called when an exception is caught, and to
c24a23b1f198 Added implementation notes for [re]set_exc_info(). Guido van Rossum <guido@python.org> parents: 28086 diff changeset	3071 have that function access the caught exception via sys.exc_ZZZ.
c24a23b1f198 Added implementation notes for [re]set_exc_info(). Guido van Rossum <guido@python.org> parents: 28086 diff changeset	3072 (Example: traceback.print_exc()).
c24a23b1f198 Added implementation notes for [re]set_exc_info(). Guido van Rossum <guido@python.org> parents: 28086 diff changeset	3073
c24a23b1f198 Added implementation notes for [re]set_exc_info(). Guido van Rossum <guido@python.org> parents: 28086 diff changeset	3074 At the same time I fixed the problem that sys.exc_ZZZ weren't
c24a23b1f198 Added implementation notes for [re]set_exc_info(). Guido van Rossum <guido@python.org> parents: 28086 diff changeset	3075 thread-safe, by introducing sys.exc_info() which gets it from tstate;
c24a23b1f198 Added implementation notes for [re]set_exc_info(). Guido van Rossum <guido@python.org> parents: 28086 diff changeset	3076 but that's really a separate improvement.

c24a23b1f198 Added implementation notes for [re]set_exc_info(). Guido van Rossum <guido@python.org> parents: 28086 diff changeset	3081 reset_exc_info() can restore them. The invariant is that
