by the frameobject dealloc when it is time for the locals to go. When
there's still a traceback object referencing this stack frame, we
don't want the local variables to disappear yet.
(Hmm... Shouldn't they be copied to the f_locals dictionary?)
- Use co->... instead of f->f_code->...; save an extra lookup of what
we already have in a local variable).
- Remove test for nlocals > 0 before setting fastlocals to
f->f_localsplus; 0 is a rare case and the assignment is safe even
then.
called with keyword arguments -- the keyword and value were leaked.
This affected for instance with a __call__() method.
Bug reported and fix supplied by Jim Fulton.
i.e., counting opcode frequencies, or (with DXPAIRS defined) opcode
pair frequencies. Define DYNAMIC_EXECUTION_PROFILE on the command
line (for this file and for sysmodule.c) to enable.
This is safe now that both intrcheck() and signalmodule.c schedule a
sigcheck() call via Py_AddPendingCall().
This gives another 7% speedup (never run such a test twice ;-).
The raise logic has one additional feature: if you raise <class>,
<value> where <value> is not an instance, it will construct an
instance using <value> as argument. If <value> is None, <class> is
instantiated without arguments. If <value> is a tuple, it is used as
the argument list.
This feature is intended to make it easier to upgrade code from using
string exceptions to using class exceptions; without this feature,
you'd have to change every raise statement from ``raise X'' to ``raise
X()'' and from ``raise X, y'' to ``raise X(y)''. The latter is still
the recommended form (because it has no ambiguities about the number
of arguments), but this change makes the transition less painful.
bltinmodule.c: fixed coerce() nightmare in ternary pow().
modsupport.c (initmodule2): pass METH_FREENAME flag to newmethodobject().
pythonrun.c: move flushline() into and around print_error().
global: Py_MakePendingCalls. Also guard against recursive calls
* Include/classobject.h, Objects/classobject.c,
Python/{ceval.c,bltinmodule.c}: entirely redone operator
overloading. The rules for class instances are now much more
relaxed than for other built-in types
(whose coerce must still return two objects of the same type)
