Marc-André Lemburg e9eeab5c05 Initial version of systimes - a module to provide platform dependent
performance measurements.

The module is currently just a proof-of-concept implementation, but
will integrated into pybench once it is stable enough.

Michael W. Hudson 96495ee6dd Quality control, meet exceptions.c, round two.
Make some functions that should have been static static.

Fix a bunch of refleaks by fixing the definition of
MiddlingExtendsException.

Remove all the __new__ implementations apart from
BaseException_new.  Rewrite most code that needs it to cope with
NULL fields (such code could get excercised anyway, the
__new__-removal just makes it more likely).  This involved
editing the code for WindowsError, which I can't test.

This fixes all the refleaks in at least the start of a regrtest
-R :: run.

Michael W. Hudson 22a80e7cb0 Quality control, meet exceptions.c.
Fix a number of problems with the need for speed code:

One is doing this sort of thing:

    Py_DECREF(self->field);
    self->field = newval;
    Py_INCREF(self->field);

without being very sure that self->field doesn't start with a
value that has a __del__, because that almost certainly can lead
to segfaults.

As self->args is constrained to be an exact tuple we may as well
exploit this fact consistently.  This leads to quite a lot of
simplification (and, hey, probably better performance).

Add some error checking in places lacking it.

Fix some rather strange indentation in the Unicode code.

Delete some trailing whitespace.

More to come, I haven't fixed all the reference leaks yet...

Fredrik Lundh 80f8e80c15 needforspeed: added Py_MEMCPY macro (currently tuned for Visual C only),
and use it for string copy operations.  this gives a 20% speedup on some
string benchmarks.

Tim Peters 5e9d6cfbda PyErr_Display(), PyErr_WriteUnraisable(): Coverity found a cut-and-paste
bug in both:  `className` was referenced before being checked for NULL.

Jack Diederich 2d40077b4f needforspeed: use PyObject_MALLOC instead of system malloc for small

Fredrik Lundh 7a83089c06 needforspeed: backed out the Py_LOCAL-isation of ceval; the massive in-
lining killed performance on certain Intel boxes, and the "aggressive"
macro itself gives most of the benefits on others.

Neal Norwitz 2f3136b8f0 Fix compiler warning (and whitespace) on Mac OS 10.4. (A lot of this code looked duplicated, I wonder if a utility function could help reduce the duplication here.) 2006-05-27 05:18:57 +00:00
Steve Holden 8040359724 Reinstate new-style object tests. 2006-05-27 00:51:52 +00:00
Tim Peters 7df5e7f4b2 Patch 1145039.
set_exc_info(), reset_exc_info():  By exploiting the
likely (who knows?) invariant that when an exception's
`type` is NULL, its `value` and `traceback` are also NULL,
save some cycles in heavily-executed code.

This is a "a kronar saved is a kronar earned" patch:  the
speedup isn't reliably measurable, but it obviously does
reduce the operation count in the normal (no exception
raised) path through PyEval_EvalFrameEx().

The tim-exc_sanity branch tries to push this harder, but
is still blowing up (at least in part due to pre-existing
subtle bugs that appear to have no other visible
consequences!).

Not a bugfix candidate.
