Neil Schemenauer 3a313e3655 Check the type of values returned by __int__, __float__, __long__,
__oct__, and __hex__.  Raise TypeError if an invalid type is
returned.  Note that PyNumber_Int and PyNumber_Long can still
return ints or longs.  Fixes SF bug #966618.

Marc-André Lemburg d2d4598ec2 Allow string and unicode return types from .encode()/.decode()
methods on string and unicode objects. Added unicode.decode()
which was missing for no apparent reason.

Fred Drake 0a4dd390bf Make weak references subclassable:
- weakref.ref and weakref.ReferenceType will become aliases for each
  other

- weakref.ref will be a modern, new-style class with proper __new__
  and __init__ methods

- weakref.WeakValueDictionary will have a lighter memory footprint,
  using a new weakref.ref subclass to associate the key with the
  value, allowing us to have only a single object of overhead for each
  dictionary entry (currently, there are 3 objects of overhead per
  entry: a weakref to the value, a weakref to the dictionary, and a
  function object used as a weakref callback; the weakref to the
  dictionary could be avoided without this change)

- a new macro, PyWeakref_CheckRefExact(), will be added

- PyWeakref_CheckRef() will check for subclasses of weakref.ref

This closes SF patch #983019.

Raymond Hettinger 214b1c3aae SF Bug #215126: Over restricted type checking on eval() function
The builtin eval() function now accepts any mapping for the locals argument.
Time sensitive steps guarded by PyDict_CheckExact() to keep from slowing
down the normal case.  My timings so no measurable impact.

Tim Peters e7c053233f sizeof(char) is 1, by definition, so get rid of that expression in

Raymond Hettinger c978633ec6 Futher improvements to frozenset hashing (based on Yitz Gale's battery of
tests which nicely highly highlight weaknesses).

* Initial value is now a large prime.
* Pre-multiply by the set length to add one more basis of differentiation.
* Work a bit harder inside the loop to scatter bits from sources that
  may have closely spaced hash values.

All of this is necessary to make up for keep the hash function commutative.
Fortunately, the hash value is cached so the call to frozenset_hash() will
only occur once per set.
2004-06-10 22:41:48 +00:00
Raymond Hettinger 27e403ebe9 Fixups to the hash function for frozensets.
* Non-zero initial value so that hash(frozenset()) != hash(0).
* Final permutation to differentiate nested sets.
* Add logic to make sure that -1 is not a possible hash value.
2004-06-10 21:38:41 +00:00
Raymond Hettinger 57c2d930f6 Add a final permutation step to the tuple hash function.
Prevents a collision pattern that occurs with nested tuples.
(Yitz Gale provided code that repeatably demonstrated the weakness.)

many more prime multipliers and that performs well on collision tests.

Goodger, Reviewed by Martin v. Loewis)

Andrew MacIntyre 4e10ed3b86 If a file is opened with an explicit buffer size >= 1, repeated
close() calls would attempt to free() the buffer already free()ed on
the first close().     [bug introduced with patch #788249]

Making sure that the buffer is free()ed in file object deallocation is
a belt-n-braces bit of insurance against a memory leak.
