Benjamin Peterson 5c8da86f3a convert usage of fail* to assert* 2009-06-30 22:57:08 +00:00
Mark Dickinson f709ab8526 Add an extra test for long <-> float hash equivalence. 2009-01-31 16:44:04 +00:00
Nick Coghlan 180e400766 Issue #4701: implicitly call PyType_Ready from PyObject_Hash 2008-12-30 01:18:48 +00:00
Nick Coghlan 48361f5cbf Issue 2235: Py3k warnings are now emitted for classes that will no longer inherit a__hash__ implementation from a parent class in Python 3.x. The standard library and test suite have been updated to not emit these warnings. 2008-08-11 15:45:58 +00:00
Nick Coghlan 53663a695e Issue 2235: __hash__ is once again inherited by default, but inheritance can be blocked explicitly so that collections.Hashable remains meaningful 2008-07-15 14:27:37 +00:00
Facundo Batista d544df7ddd Issue #1772851. Alters long.__hash__ from being *almost* completely
predictable to being completely predictable.  The value of hash(n)
is unchanged for any n that's small enough to be representable as an
int, and also unchanged for the vast majority of long integers n of
reasonable size.

Walter Dörwald 70a6b49821 Replace backticks with repr() or "%r"
From SF patch #852334.

Barry Warsaw 04f357cffe Get rid of relative imports in all unittests. Now anything that
imports e.g. test_support must do so using an absolute package name
such as "import test.test_support" or "from test import test_support".

This also updates the README in Lib/test, and gets rid of the
duplicate data dirctory in Lib/test/data (replaced by
Lib/email/test/data).

Now Tim and Jack can have at it. :)

Fred Drake 2e2be3760c Change the PyUnit-based tests to use the test_main() approach. This
allows using the tests with unittest.py as a script.  The tests will
still run when run as a script themselves.

Fred Drake 004d5e6880 Make reindent.py happy (convert everything to 4-space indents!). 2000-10-23 17:22:08 +00:00
Fred Drake 13634cf7a4 This patch addresses two main issues: (1) There exist some non-fatal
errors in some of the hash algorithms. For exmaple, in float_hash and
complex_hash a certain part of the value is not included in the hash
calculation. See Tim's, Guido's, and my discussion of this on
python-dev in May under the title "fix float_hash and complex_hash for
64-bit *nix"

(2) The hash algorithms that use pointers (e.g. func_hash, code_hash)
are universally not correct on Win64 (they assume that sizeof(long) ==
sizeof(void*))

As well, this patch significantly cleans up the hash code. It adds the
two function _Py_HashDouble and _PyHash_VoidPtr that the various
hashing routine are changed to use.

These help maintain the hash function invariant: (a==b) =>
(hash(a)==hash(b))) I have added Lib/test/test_hash.py and
Lib/test/output/test_hash to test this for some cases.
