Neal Norwitz 8b2bfbc198 Add -3 option to the interpreter to warn about features that are
deprecated and will be changed/removed in Python 3.0.

This patch is mostly from Anthony.  I tweaked some format and added
a little doc.

Raymond Hettinger 0bbbfc4c0b Extend work on rev 52962 and 53829 eliminating redundant PyObject_Hash() calls and fixing set/dict interoperability. 2007-03-20 21:27:24 +00:00
Neal Norwitz ee3a1b5244 Variation of patch # 1624059 to speed up checking if an object is a subclass
of some of the common builtin types.

Use a bit in tp_flags for each common builtin type.  Check the bit
to determine if any instance is a subclass of these common types.
The check avoids a function call and O(n) search of the base classes.
The check is done in the various Py*_Check macros rather than calling
PyType_IsSubtype().

All the bits are set in tp_flags when the type is declared
in the Objects/*object.c files because PyType_Ready() is not called
for all the types.  Should PyType_Ready() be called for all types?
If so and the change is made, the changes to the Objects/*object.c files
can be reverted (remove setting the tp_flags).  Objects/typeobject.c
would also have to be modified to add conditions
for Py*_CheckExact() in addition to each the PyType_IsSubtype check.

the tuple isn't used as the "exception arguments tuple".

Neal Norwitz a5ccda95f2 Fix warnings with HP's C compiler. It doesn't recognize that infinite
loops are, um, infinite.  These conditions should not be able to happen.

Will backport.

Tim Peters d770ebd286 Armin committed his patch while I was reviewing it (I'm sure
he didn't know this), so merged in some changes I made during
review.  Nothing material apart from changing a new `mask` local
from int to Py_ssize_t.  Mostly this is repairing comments that
were made incorrect, and adding new comments.  Also a few
minor code rewrites for clarity or helpful succinctness.

Tim Peters 9b10f7e0cb Convert relevant dict internals to Py_ssize_t.
I don't have a box with nearly enough RAM, or an OS,
that could get close to tickling this, though (requires
a dict w/ at least 2**31 entries).
2006-05-30 04:16:25 +00:00
Thomas Wouters c6e55068ca Use Py_VISIT in all tp_traverse methods, instead of traversing manually or
using a custom, nearly-identical macro. This probably changes how some of
these functions are compiled, which may result in fractionally slower (or
faster) execution. Considering the nature of traversal, visiting much of the
address space in unpredictable patterns, I'd argue the code readability and
maintainability is well worth it ;P

Guido van Rossum 4b92a82504 Oops. Fix syntax for C89 compilers. 2006-02-25 23:32:30 +00:00
Guido van Rossum 1968ad32cd - Patch 1433928:
- The copy module now "copies" function objects (as atomic objects).
  - dict.__getitem__ now looks for a __missing__ hook before raising
    KeyError.
  - Added a new type, defaultdict, to the collections module.
    This uses the new __missing__ hook behavior added to dict (see above).

Guido van Rossum 09240f65f8 GCC was complaining that 'value' in dictiter_iternextvalue() wasn't
necessarily always set before used.  Between Tim, Armin & me we
couldn't prove GCC wrong, so we decided to fix the algorithm.  This
version is Armin's.
